Risk and Capital Management - Pillar 3 __________________________________________________________________________________________ __________________________________________________________________________________________ Itaú Unibanco 1 Objective This document presents Itaú Unibanco Holding S.A. (Itaú Unibanco) information required by the Central Bank of Brazil (BACEN) through Resolution BCB nº 54 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 members. 1 The referred Resolution 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 September 30, 2026, are summarized below. 1 Compensation of management members data is reported annually.

Risk and Capital Management - Pillar 3 __________________________________________________________________________________________ __________________________________________________________________________________________ Itaú Unibanco 4 The Basel Index reached 15.2% on December 31, 2025, a decrease of 1.2 p.p. compared to September 30, 2025, due to the payment of dividends and interest on equity, share buybacks, and the growth of risk‑weighted assets, partially offset by the positive impact of the period’s result Besides, Itaú Unibanco has a R$ 121,150 million capital excess in relation to its minimum required Total Capital. It corresponds to 7,4 p.p. above the minimum requirement (8%) and higher than the Capital Buffer requirement of 3.6% (R$ 57,895 million). Considering the Capital Buffers, the capital excess would be 3,9 p.p. The fixed assets ratio shows the commitment percentage of adjusted Total Capital with the adjusted permanent assets. Itaú Unibanco falls within the maximum limit of 50% of adjusted Total Capital, established by BACEN. On September 30, 2026, fixed assets ratio reached 18.1%, showing a surplus of R$ 80,123 million. OVA – Bank risk management approach Scope and Key Features of Risk Management Taking and managing risks is one of Itaú Unibanco’s activities, and to do so effectively, the institution must have well-established objectives for risk management. In this context, the Risk Appetite articulates the set of guidelines from the Board of Directors (BoD) regarding strategy and risk-taking, defining the nature and level of acceptable risks for the organization, while the risk culture guides the necessary attitudes for managing them. Itaú Unibanco invests in robust risk and capital management processes that permeate the entire institution and form the foundation for strategic decisions to ensure business sustainability and maximize shareholder value. Among the processes for proper risk and capital management, the following stand out: the implementation of a continuous and integrated risk management framework; the Risk Appetite Framework, which consists of the Risk Appetite Statement (RAS) from the BoD, the Risk Appetite Policy, and a set of metrics for monitoring key risks according to defined limits; the stress testing program; the establishment of a Risk Committee; and the appointment, before the Central Bank of Brazil (BACEN), of a Chief Risk Officer (CRO) with clearly defined roles, responsibilities, and independence requirements. These processes are aligned with the guidelines of the BoD and Executives, who, through collegiate bodies, define global objectives expressed in goals and limits for the risk-managing business units. The capital control and management units, in turn, support Itaú Unibanco’s management through risk and capital monitoring and analysis processes. The principles that underpin risk management, Risk Appetite, and the guidelines for how Itaú Unibanco employees should act in their daily decision-making are: • Sustainability and customer satisfaction: Itaú Unibanco's vision is to be the leading bank in sustainable performance and customer satisfaction. Therefore, it is committed to generating shared value for employees, customers, shareholders, and society, ensuring business continuity. Itaú Unibanco is focused on conducting business that benefits both the customer and the institution. • Risk culture: The institution's risk culture goes beyond policies, procedures, and processes, aiming to strengthen the individual and collective responsibility of all employees to do the right thing, at the right time, and in the right way, respecting ethical business practices. It is based on four principles (conscious risk-taking, discussion and action on institutional risks, and everyone's responsibility for risk management), which encourage open understanding and discussion of risks, keeping them within the levels determined by the Risk Appetite, and ensuring that each employee, regardless of position, area, or function, also assumes responsibility for managing the risks of their business. The Risk Culture is detailed in the "Risk Culture" section.
Risk and Capital Management - Pillar 3 __________________________________________________________________________________________ __________________________________________________________________________________________ Itaú Unibanco 5 • Risk Pricing: Itaú Unibanco operates and assumes risks in businesses that are well-known and understood, avoiding risks in which it lacks knowledge or competitive advantage, carefully evaluating the risk- return relationship. • Diversification: The institution has a low appetite for volatility in results and therefore operates on a diversified base of customers, products, and businesses, seeking risk differentiation and prioritizing less risky ventures. • Operational excellence: Itaú Unibanco aims to be an agile bank with robust and stable infrastructure to offer high-quality services. • Ethics and respect for regulations: For Itaú Unibanco, ethics are non-negotiable. The institution promotes an environment of integrity, guiding all employees to cultivate ethics in relationships and business and respect regulations, safeguarding the institution's reputation. Risk and Capital Governance The Board of Directors is the highest authority responsible for establishing guidelines, policies, and limits for risk and capital management. The Risk and Capital Management Committee (CGRC) supports the Board in fulfilling its duties related to risk and capital oversight. At the executive level, collegiate bodies chaired by Itaú Unibanco's Chief Executive Officer (CEO) are responsible for risk and capital management, exercising delegated responsibilities in these areas, and their decisions are monitored within the scope of the CGRC. To support this structure, the Risk Area has specialized departments aimed at ensuring, independently and centrally, that the institution’s risks and capital are managed in accordance with established policies and procedures. Itaú Unibanco’s risk management organizational structure complies with current regulations in Brazil and abroad. Domestically, the Bank follows the rules established by the Central Bank of Brazil (BACEN), particularly Resolution No. 4,557/17, which addresses the risk and capital management framework for financial institutions, as well as regulations from the Brazilian Securities and Exchange Commission (CVM) and the Private Insurance Superintendence (SUSEP), among other regulators and applicable standards. Internationally, Itaú Unibanco adheres to standards set by the Basel Committee on Banking Supervision, the United States Securities and Exchange Commission (SEC), and local regulations in the countries where it operates. Additionally, Itaú Unibanco complies with guidelines such as the Foreign Account Tax Compliance Act (FATCA), the Principles for Responsible Banking (PRB) of the United Nations Environment Programme – Finance Initiative, and the Guidelines for Multinational Enterprises of the Organization for Economic Cooperation and Development (OECD), among other representative examples. The Bank also adopts practices aligned with International Financial Reporting Standards (IFRS) and globally recognized corporate governance best practices. Furthermore, Itaú Unibanco has a governance framework for identifying and monitoring emerging risks—those newly identified risks with potentially material medium- to long-term impacts on the business, but for which there is still insufficient information for full assessment due to the number of unknown factors and impacts, as they are unprecedented and have not been addressed in the past. Risk management responsibilities at Itaú Unibanco are structured according to the three lines of governance model: • 1st line of governance: Business and corporate support areas are directly responsible for identifying, measuring, assessing, monitoring, reporting, controlling, and mitigating the risks they originate;
Risk and Capital Management - Pillar 3 __________________________________________________________________________________________ __________________________________________________________________________________________ Itaú Unibanco 6 • 2nd line of governance: The Risk Area aims to ensure, independently and centrally, that the institution’s risks are managed according to established policies and procedures, defining parameters for the risk management process and its supervision. This control provides the BoD and executives with a comprehensive view of Itaú Unibanco’s exposures, optimizing and accelerating corporate decision-making; • 3rd line of governance: Internal Audit, which reports to the Board of Directors, conducts independent evaluations of the activities carried out within the institution, enabling senior management to assess the adequacy of controls, the effectiveness of risk management, and compliance with internal policies and regulatory requirements. Itaú Unibanco uses robust, automated systems to fully comply with capital regulations and to measure risks, in accordance with current regulatory models and requirements. It also coordinates actions to ensure compliance with both qualitative and quantitative requirements set by regulators for minimum capital observation and risk monitoring. Ituber Culture Risk management is an intrinsic and transversal element in Ituber culture, which emphasizes the individual responsibility of each employee, regardless of hierarchical level, guiding decisions and attitudes based on ethics and the reduction of risks that may affect the business, customers and society. As an essential part of organizational culture, risk management influences performance evaluation, which considers each employee's alignment with the company's values, with emphasis on the following aspects: • For us, ethics are non-negotiable: integrity permeates all decisions and actions, strengthening risk management • We are driven by results: sustainable growth is prioritized, with attention to the risks and impacts of solutions, ensuring security and long-term vision • We don't have all the answers: decision making is data-driven, enabling risk identification and mitigation • We have each other’s back: teamwork and flagging critical issues at the right time are essential to avoid or mitigate risks • We treasure diversity and inclusion: knowledge of socio-environmental opportunities and risks is essential for the development of responsible business. Ituber culture reinforces that risk management is not just a practice, but a value that permeates all dimensions of the business.

Risk Appetite The Risk Appetite articulates the set of guidelines from the Board of Directors (BoD) regarding strategy and risk- taking, defining the nature and level of acceptable risks for the organization while considering the capacity for effective and prudent management, strategic objectives, competitive conditions, and the regulatory environment. The Risk Appetite framework consists of the Risk Appetite Statement (RAS) from the BoD, the Risk Appetite Policy, and a set of metrics for monitoring key risks according to defined limits. Considering Itaú Unibanco’s strategic guidelines, the Risk Appetite and its dimensions are based on the following statement:
Risk and Capital Management - Pillar 3 __________________________________________________________________________________________ __________________________________________________________________________________________ Itaú Unibanco 7 “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.” To make the RAS tangible, the Risk Appetite is organized in six dimensions, each composed of a set of metrics associated with the key risks involved, combining complementary measurement methods to obtain a comprehensive view of our exposures to acceptable types and levels of risk: • Capitalization: Reflects the Bank’s level of protection against significant losses that could lead to regulatory non-compliance or insolvency. It establishes that Itaú Unibanco must have sufficient capital to withstand a severe recession or stress event without needing to adjust its capital structure under adverse circumstances. It is monitored through the tracking of Itaú Unibanco’s capital ratios under normal and stressed conditions, as well as the institution’s debt issuance ratings. • Liquidity: Reflects the Bank’s level of protection against a prolonged funding stress period that could lead to a liquidity shortfall and eventual bankruptcy. It establishes that Itaú Unibanco’s liquidity must endure extended periods of stress. It is monitored through the tracking of liquidity indicators. • Breakdown of results: Aims to ensure stability and sustainability of results, restricting excessive volatility and avoiding portfolio concentrations and significant deviations in pricing and provisions. It defines that business will primarily 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. It monitors Credit risk indicators, including social, environmental, and climate dimensions, Market and IRRBB risks, Underwriting risks, and Business & Profitability risks. The monitored metrics aim to ensure, through exposure concentration limits (e.g., industry sectors, counterparty quality, countries and geographic regions, and risk factors), an appropriate portfolio composition, targeting low earnings volatility and business sustainability. • Operational risk: Addresses operational risks that could compromise the Bank’s business and operations, focusing on controlling events that could negatively impact business strategy and operations. • Reputation: Addresses risks that could impact the value of our brand and the institution’s reputation among customers, employees, regulators, investors, and the general public. Risk monitoring in this dimension is carried out through ethical behavior and conservative adherence to regulatory standards. • Clients: Addresses risks that could impact customer satisfaction and experience, monitored through customer satisfaction tracking, events with direct customer impact, and suitability indicators. The metrics translate the RAS and dimensions into measurable indicators that capture the main risks incurred by the institution. They are periodically monitored and reported to the executive level, the Risk and Capital Management Committee (CGRC), and the BoD, which guide preventive actions to ensure exposures remain within established limits and aligned with our strategy. The Board of Directors is responsible for establishing and approving the Risk Appetite guidelines and limits, performing its duties with the support of the CGRC and the Chief Risk Officer (CRO). The Risk Appetite governance is documented in an internal policy, which is also established, reviewed, and approved by the BoD. 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
Risk and Capital Management - Pillar 3 __________________________________________________________________________________________ __________________________________________________________________________________________ Itaú Unibanco 8 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. 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 and Resolution Plan In response to recent international financial crises, the Central Bank of Brazil issued Resolution No. 5,187 and BCB Resolution No. 440/24, requiring financial institutions classified within Segment 1 whose total exposure exceeds 10% of Brazil’s GDP to develop a Recovery and Orderly Exit Plan (PRSO). The Recovery Plan aims to restore adequate levels of capital and liquidity, above regulatory operating limits, in the event of severe systemic or idiosyncratic stress scenarios.The Orderly Exit Plan, in turn, consists of a set of measures adopted or determined by the Central Bank of Brazil when an institution is deemed non-viable or is expected to become non- viable, with the objective of mitigating adverse effects on the stability of the National Financial System (SFN), the Brazilian Payment System (SPB), and the real economy arising from the discontinuation of the institution’s activities. Itaú Unibanco has a report that contemplates the entire Conglomerate and contains the description of the following items: I. Critical functions: activities performed by the entities within the scope of recovery and resolution planning for third parties, whose discontinuity could compromise the stability of the National Financial System (SFN), the Brazilian Payment System (SPB), or the real economy, due to their market share, interconnections, complexity, or other factors that prevent them from being immediately replaced by the market. II. Institution's essential services: services provided to one or more entities within the scope of recovery and resolution planning, whose disruption would impair the functioning of a core business line;
Risk and Capital Management - Pillar 3 __________________________________________________________________________________________ __________________________________________________________________________________________ Itaú Unibanco 9 III. Bridge institution: an entity established or reorganized to which assets, rights, and obligations of the institution under resolution are transferred, in whole or in part, aiming at the general or partial continuity of its business or activity. IV. Core business lines: activities essential to the viability of the prudential conglomerate or economic group under normal conditions, as they are material sources of revenue, capital gains, or market value. V. 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 and Resolution Plan; VI. 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; VII. Recovery and Resolution 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; VIII. Communication plan with stakeholders, seeking its timely execution with the market, regulators and other stakeholders; IX. Governance mechanisms necessary for the coordination and execution of the Recovery and Resolution Plan, such as the definition of the director responsible for the exercise at Itaú Unibanco. This plan is reviewed biennially, whenever there are material changes or as determined by Bacen, and is subjected to the approval of the Board of Directors. With this practice, Itaú Unibanco has been able to continuously demonstrate, 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 and resolution plans; • Preparation of management and regulatory reports. 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 Normative Instruction 322.
Risk and Capital Management - Pillar 3 __________________________________________________________________________________________ __________________________________________________________________________________________ Itaú Unibanco 10 The result of the last ICAAP, which includes stress tests – dated as of December 2024 – 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.

Risk and Capital Management - Pillar 3 __________________________________________________________________________________________ __________________________________________________________________________________________ Itaú Unibanco 12 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. The process and methodology are evaluated periodically and independently by internal controls and internal audit. In the line Other Differences of the table LI2, are reported the transactions subject to credit risk and counterparty credit risk, which are not accounted for in the balance sheet or in the off-balance sheet amounts.

Risk and Capital Management - Pillar 3 __________________________________________________________________________________________ __________________________________________________________________________________________ Itaú Unibanco 25 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.

In addition, the Required Stable Funding (RSF) amounted to billion in the 3 quarter, which is mostly composed of loans and financing granted to wholesale, retail, central economies and central bank operations. The table shows that the NSFR at the end of the quarter is 123,7% , above the limit of 100%, and therefore the institution has Available Stable Funding to support the Required Stable Funding comfortably in the long- term, according to the metric.
Risk and Capital Management - Pillar 3 __________________________________________________________________________________________ __________________________________________________________________________________________ Itaú Unibanco 28 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, with the periodic monitoring of troubled assets, which are defined as: • Overdue Transactions for more than 90 days; • Restructured Operations; • Counterparties that present inability to pay, whether by legal measures, judicial reorganization, bankruptcy, loss, among others; • Significant deterioration in credit quality, which can be identified by deterioration in internal rating metrics, guarantees honored, among others. Additionally, if it is identified that a CNPJ may contaminate the counterparties, they may be marked as Troubled Assets. The monitoring contains information on significant exposures, including recovery history and prospects, as well as restructuring information. These analyzes are generated monthly for executives and quarterly for the Board of Directors through the Risk and Capital Management Committee (CGRC). 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.
Risk and Capital Management - Pillar 3 __________________________________________________________________________________________ __________________________________________________________________________________________ Itaú Unibanco 29 With respect to individuals, small and medium companies, retail public, the 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 wholesale public e agro, the 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 also has a specific structure and processes aimed at ensuring that other aspects of credit risk, such as country risk, are managed and controlled, described in the item “Other Risks”. In compliance with CMN Resolution 4,557, the document “Public Access Report: Credit Risk Management and Control Policy", which describes the guidelines established in the institutional ruling on credit risk control, can be viewed on the website www.itau.com.br/investor-relations, section “Itaú Unibanco”, under “Corporate Governance”, “Policies”, “Reports”.

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 financial, credit derivatives, fiduciary, real, legal structures with mitigation power and offsetting agreements. For these guarantees to be considered as credit risk mitigating instruments, it is necessary that they comply with the requirements and determinations of the that regulate them, whether internal or external, and that they are legally enforceable (effective), enforceable and regularly evaluated. The information regarding the possible concentration associated with the mitigation of credit risk considers these 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 the general requirements. • Fiduciary Guarantees and credit derivatives: a third party assumes the responsibility for fulfilling the obligation contracted by the debtor, which falls on the general equity of that third party. Avals, sureties and CDS are examples of these guarantees. Fiduciary guarantees are segregated into the following providers: Legal Entities; Multilateral Development Entities (EMD); Financial Institutions, Sovereigns, National Treasury or Central Bank. 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. They are also segregated into: Legal Entities; Multilateral Development Entities (EMD); Financial Institutions and Sovereigns. • Real and Financial Guarantees: the borrower itself or a third party detaches one or more financial assets and/or one or more goods and/or one or more receivables, in such a way as to guarantee repayment to the creditor in the event of default. These guarantees are segregated by type: financial collateral, bilateral contracts, and assets.
Risk and Capital Management - Pillar 3 __________________________________________________________________________________________ __________________________________________________________________________________________ Itaú Unibanco 33 • Clearing and Settlement of Obligations Agreement and legal structures with mitigating power: the clearing agreement aims to reduce the risk of credit exposure of one party to the other, resulting from transactions entered into between them, so that, in case of maturity, after offsetting, the net amount owed by the debtor to the creditor is identified. It is commonly used in derivative transactions, but it can also cover other types of financial transactions. In legal structures with mitigation power and compensation agreements, mitigation is based on methodologies established and approved by the business units responsible for credit risk management and by the centralized credit risk control area. Such methodologies consider factors related to the legal enforceability of the guarantees, the costs necessary for such and the expected value in the execution, taking into account the volatility and liquidity of the market. To control the mitigating instruments, there is periodic monitoring that monitors the level of compliance with the use of each instrument when compared to internal measurement policies, even including corrective action plans when there is noncompliance, analyzing concentration, types, providers, formalization. The parameters used are: HE (Haircut of execution) which evaluates the probability of success in executing the guarantee, HV (Volatility Haircut) represents the liquidity of the collateral being offered, and LMM (Maximum Mitigation Limit) which is the mitigation ceiling for real guarantees.

CRE: Qualitative disclosure related to IRB models To calculate regulatory credit risk capital, two approaches can be used, the standardized and the IRB (Internal Ratings Based). standardized and IRB (Internal Ratings Based). Itaú Unibanco was approved to use the IRB approach by the Central Bank for its rural credit business unit (Agribusiness). The IRB approach allows the use of internal models to calculate regulatory capital for credit risk, To this end, internal estimates of Probability of Default (PD), Loss Given Default (LGD) and Exposure at Default (EAD) are used. A client's PD is directly associated with its internal credit risk rating. This rating is based on internal models used in the loan granting process. This classification is based on financial and qualitative aspects of individual customers. Since PD is the probability of a creditor defaulting, it is estimated based on the portfolio information. The calculation seeks to predict the possibility of default occurring in the next twelve months for each credit rating, using the average profile of the portfolio over the last five years, in accordance with BCB Resolution No. 303. In addition, we respect the 0.05% floor for PD values, as established in Chapter II of the regulation. The EAD is the expected value for the creditor's balance at the time of default. This value is derived from the balance at the time of valuation combined with possible movements that may the debtor balance up to the moment of default, considering the possibility of credit available to the client. In order to estimate the FCC (Credit Conversion Factor), credit conversion data was used considering the balances and credit conversion considering creditors' available balances and limits 12 months before the moment of default for revolving products. The financial institution stores data for a period of seven years, fulfilling the minimum requirement set out in Article 102 of Resolution No. 303. The LGD is the estimation of the percentage of EAD that the institution will fail to recover in the event of default.
Risk and Capital Management - Pillar 3 __________________________________________________________________________________________ __________________________________________________________________________________________ Itaú Unibanco 40 This estimation is based on the events of default that have occurred and the subsequent behavior of net recoveries at present values1. Using the minimum period required by Article 102 of Resolution No. 303 as a starting point, recovery data is stored for a workout period sufficient to capture at least 90% of the observed recovery flow and clients after the moment of default. In the process of assigning the LGD parameter to each customer within the institution, possible factors that mitigate potential future losses are taken into account in order to obtain a fair value of this parameter, these mitigations are in compliance with the Resolution No. 303. In addition to the parameter models, the agribusiness portfolio has a set of models that are used to rank and classify the risk of the different counterparties (Risk Rating and Behavior Score models), based on the size of the counterparty, the niche in which it operates and the commercial strategy of the segment. The models used in the concession process are developed by the modeling area in partnership with the credit analysis area, based on information from clients' financial statements, their history of behavior with the institution and in the market, in the evaluation of its management and governance process through internal data, bureaus and market information. These models assign a credit rating/score to each of the creditors allowing them to segregate very low-risk clients from higher-risk clients within an internal classification. Based on this internal classification assigned the risk parameters that will be used in the process of measuring and managing risk and, consequently, estimating capital in accordance with the methodology defined by the Central Bank in BCB Resolution 303. Each of the models listed above goes through an approval governance that involves the area area and the independent validation area. The area is in a segregated structure from the validation area in order to guarantee independence of action. The decision on whether or not to approve or not of the model is made in the Comitê Técnico de Avaliação de Modelos (Technical Committee for Model Evaluation) where information about the model is presented, such as scope, definition of use, replicability, stability, adherence, discrimination and, finally, the opinion of the validation area. After this process, the model is still subject to periodic annual evaluations in order to determine whether or not there is a need for adjustments to the model. This monitoring is carried out by the independent validation area and its results can be found in table CR9 of this report. Additionally, the operational risk and internal audit teams evaluate the adherence of the models in relation to the normative aspects of BCB Resolution 303 itself.

It encompasses derivative financial instruments, settlement pending transactions, securities lending and repurchase transactions. Itaú Unibanco has well-defined rules for calculating its managerial and regulatory exposure to this risk, and the models developed are used both for the governance of consumption of limits and management of counterparties sub-limits, as well as for the allocation of capital, respectively. The managerial volatility of the potential credit risk (PCR) of derivatives (interpreted as the amount of potential financial exposure that an operation can reach until its maturity) and the volatility of repurchase agreements and foreign exchange transactions are monitored periodically to maintain the exposure at levels considered acceptable by the institution's management. 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.

Securitisation Exposures SECA: Qualitative disclosure requirements related to securitisation exposures Currently, Itaú Unibanco coordinates and distributes issues of securitized securities in the capital market with or without a firm placement guarantee. In case of exercising the firm guarantee, the bank will assume the risk as an investor in the operation. Itaú Unibanco is also in the position of investor, where the institution acquires the operations with priority classes, senior, mezzanine or subordinated, of the issuing vehicles. The investment decision process involves various factors, including risk analysis of the underlying assets, risk profile of the assets, return attributed to the issues, subordination mechanisms, among others. Itaú Unibanco does not act as a sponsoring counterpart of any specific purpose company with the objective of operating in the securitisation 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 securitisations are accounted for as well as other assets owned by the Bank, according to the brazilian accounting standards; and (ii) securitisation credits originating from Itaú Unibanco's own portfolio remain accounted for in cases of credit assignment with co-obligation.

Risk and Capital Management - Pillar 3 __________________________________________________________________________________________ __________________________________________________________________________________________ Itaú Unibanco 47 Market Risk MRA: Qualitative disclosure requirements related to market risk Market risk is the possibility of losses resulting from fluctuations in the market values of positions held by a financial institution, including the risk of operations subject to variations in foreign exchange rates, interest rates, equity and commodity prices, as set forth by CMN. 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 Resolution 111. 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); • 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
Risk and Capital Management - Pillar 3 __________________________________________________________________________________________ __________________________________________________________________________________________ Itaú Unibanco 48 • 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.

Risk and Capital Management - Pillar 3 __________________________________________________________________________________________ __________________________________________________________________________________________ Itaú Unibanco 51 Itaú Unibanco, for regulatory purposes, uses the historical simulation methodology to calculate the VaR and Stressed VaR. 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 September 30, 2026, VaR represented 46% of the capital requirement, while the stressed VaR represented 54%. The same methodology 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 non-linear 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.

Risk and Capital Management - Pillar 3 __________________________________________________________________________________________ __________________________________________________________________________________________ Itaú Unibanco 52 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:

For the purposes of this Circular, are defined: • ∆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; • ∆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.
Risk and Capital Management - Pillar 3 __________________________________________________________________________________________ __________________________________________________________________________________________ Itaú Unibanco 55 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 ∆EVE and ∆NII. ∆EVE results do not represent immediate impact in the stockholders’ equity. Meanwhile, ∆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 ∆EVE and ∆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 ∆EVE and ∆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- linear payoffs. The linear payoffs are treated similarly to any other instruments without options, and for non-linear payoffs an additional value is computed and added on the ∆EVE and ∆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
Risk and Capital Management - Pillar 3 __________________________________________________________________________________________ __________________________________________________________________________________________ Itaú Unibanco 56 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: • ∆EVE and ∆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; ORA – Qualitative Information on Operational Risk Management Operational Risk Management Policies and Strategies Operational risk management at Itaú Unibanco follows a structured and continuous process, aligned with the Operational Risk Management Policy, encompassing the following stages: identification, assessment, response, monitoring, and reporting of operational risks. The strategies adopted aim to ensure that the residual risk remains within the risk appetite levels approved by Senior Management, considering changes in the internal and external environments, as well as the criticality of processes, products, and services Organizational Structure, Roles, and Responsibilities Itaú Unibanco adopts the three lines of defense model, in accordance with the best practices of the Institute of Internal Auditors (IIA): First Line: business and support areas, directly responsible for identifying, assessing, responding to, monitoring, and reporting operational risks inherent to their processes. Second Line: represented by the Risk Area, under the coordination of the Compliance & OpRisk Directorate (DCOR), whose mission is to enable the management of operational and regulatory risks, independently supporting the first line and contributing to decision-making that maximizes sustainable value for the bank, ensuring compliance and customer centricity through a risk-based approach. It is responsible for independently
Risk and Capital Management - Pillar 3 __________________________________________________________________________________________ __________________________________________________________________________________________ Itaú Unibanco 57 overseeing the effectiveness of operational risk management, issuing independent opinions on the control environment, and defining methodologies, parameters, and tools. Third Line: carried out by Internal Audit, independently evaluating the adequacy and effectiveness of risk management processes and internal controls on a periodic basis. The Chief Risk Officer (CRO) is responsible for ensuring an adequate operational risk management structure and for communication with higher governance bodies. Systems, Routines, and Procedures: The institution maintains systems and structured routines for capturing, consolidating, and analyzing operational loss events, as well as for the continuous monitoring of the control environment, using data analysis techniques and risk indicators. This information supports the timely assessment of failures and the addressing of their root causes. Management Reporting and Governance Operational risk reporting is conducted periodically and in a structured manner through governance forums, considering criteria such as relevance, materiality, and severity of operational losses and incidents. At the Board of Directors level, discussions take place within the Risk and Capital Management Committee, established in compliance with CMN Resolution No. 4,557 of February 23, 2017, whose purpose is to support the Board in fulfilling its responsibilities related to risk management, including operational and regulatory risks. Additionally, the Audit Committee, which operates in accordance with CMN Resolution No. 4,910 of May 27, 2021, among its duties, evaluates the quality and effectiveness of internal control systems and existing risk management frameworks and receives updates on these topics in periodic meetings held for this specific purpose. For the Executive Committee, reporting is carried out in specific forums, such as the Senior Compliance & OpRisk Commission (CSCOR), which includes the participation of the CEO of Itaú, members of the Executive Committee (including the Holding CRO), and the Executive Director of Internal Audit. This quarterly forum is responsible for understanding risks in business processes and support areas, assessing the results of the Internal Control System, and defining guidelines for operational and regulatory risk management. Additionally, there are specific forums for each business unit and support area, namely the Compliance & OpRisk Committees (CCOR), involving the Executive Committee Member (ECM), held at least three times a year, with participation from the responsible ECM and the Compliance & OpRisk Director. Their responsibilities include understanding area risks, responding to identified risks, monitoring action plans for improving the control environment, and addressing relevant methodological changes. Relevant events or significant exceptions may trigger extraordinary reporting to governance bodies, including the Executive Board, Risk Committees, Audit Committee, and Board of Directors, through the aforementioned forums. Operational Risk Mitigation Strategies Operational risk mitigation strategies include: - Adoption of structured risk responses (acceptance, mitigation, transfer, or avoidance), aligned with the risk appetite; - Strengthening of the internal control environment, through monitoring, testing, and action plans; - Dissemination of risk, compliance, and ethics culture through continuous training and awareness programs;

Risk and Capital Management - Pillar 3 __________________________________________________________________________________________ __________________________________________________________________________________________ Itaú Unibanco 59 OR3: Capital Requirement for Operational Risk 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. 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, Environmental and Climatic Risks Environmental, Social and Climate Risks refer to the possibility of losses arising from exposure to events of social, environmental and/or climate origin related to the activities carried out by ITAÚ UNIBANCO HOLDING CONSOLIDADO. Such events may affect the sustainability of our business, the resilience of our assets and value creation over the short, medium and long terms. The Social, Environmental and Climate Risk Policy (ESC Risk Policy) establishes the guidelines and fundamental principles for the management of social, environmental and climate risks. It addresses the risks most relevant to the institution’s operations through specific procedures, in alignment with applicable corporate policies. 09/30/2026 Weighted Business Indicator (BIC) 21.833 Internal Loss Multiplier (ILM) 96,920% Capital requirement for operational risk 21.160 RWAopad 264.498
Risk and Capital Management - Pillar 3 __________________________________________________________________________________________ __________________________________________________________________________________________ Itaú Unibanco 60 To mitigate Social, Environmental and Climate Risks, ITAÚ UNIBANCO HOLDING CONSOLIDADO carries out process, risk and control mapping activities, monitors new regulations related to the topic and records identified occurrences in internal systems. In addition to risk identification, the stages of prioritization, risk response, mitigation, monitoring and reporting complement the management of the risks assessed. Risk management follows the three lines of defense model. First-line areas, represented by the business units, are responsible for managing risks in their day-to-day activities, in accordance with the guidelines of the ESC Risk Policy and specific procedures, supported by specialized technical assessments carried out by dedicated teams, such as those in the Credit area. Business support areas, including Sustainability and Institutional Legal, also rely on specialized teams that work in an integrated manner to manage all dimensions of Social, Environmental and Climate Risks associated with the conglomerate’s activities. Second-line areas, such as Social, Environmental and Climate Risk and Internal Controls, provide oversight, methodological support and ensure the appropriate governance of business and credit activities. In the third line, Internal Audit operates independently, performing assessments of risk management, controls and governance. The institution has specific procedures in place for the management of Social, Environmental and Climate risks in its own operations — including assets, branch infrastructure, technology and suppliers — as well as within traditional risk categories such as credit, investments and key subsidiaries. These procedures are designed in accordance with the principles of relevance and proportionality and range from the verification of information in applicable public databases for clients and suppliers to in-depth individual analyses for selected clients, depending on the segment or type of product. The governance structure also includes the Social, Environmental and Climate Risk Committee, whose primary responsibility is to assess and deliberate on institutional and strategic matters, as well as on products, operations and services that involve Social, Environmental and Climate Risks. Given the relevance of climate risk, ITAÚ UNIBANCO HOLDING CONSOLIDADO supports the Task Force on Climate-related Financial Disclosures (TCFD) and is committed to maintaining a process of continuous improvement aligned with its recommendations. In addition, the institution measures the sensitivity of its loan portfolio to climate risks through the application of the Climate Risk Sensitivity Scale, which categorizes clients and sectors by considering both physical risks — arising from changes in climate patterns, such as increased rainfall, rising temperatures and extreme weather events — and transition risks, resulting from economic changes driven by climate-related actions, including carbon pricing, climate regulation, market risks and reputational risks. Operational and Compliance Risk Compliance and operational risks are defined as the possibility of losses resulting from external events or failures in internal processes, people, or systems, or from non-compliance with legal and regulatory requirements. The methodology supporting the management of these risks adheres to market best practices, trends, and applicable regulations, with emphasis on the principles of Basel, COSO (Committee of Sponsoring Organizations of the Treadway Commission), COBIT (Control Objectives for Information and Related Technologies), and IIA (The Institute of Internal Auditors), as well as the intensive use of artificial intelligence to challenge the status quo.
Risk and Capital Management - Pillar 3 __________________________________________________________________________________________ __________________________________________________________________________________________ Itaú Unibanco 61 Model Risk Model risk is the fianancial risk, regulatory and reputational impact arising from errors in the production of models, their use, or associated with the data required for their application. The use of models has become increasingly prevalent within the institution, supporting strategic decisions in various contexts such as credit approval, transaction pricing, volatility curve estimation, capital calculation, among others. Due to the growing use of models—driven by the application of new technologies and the expanded use of data— Itaú Unibanco continues to enhance its governance related to the development, implementation, use, and monitoring of these models by defining guidelines, policies, and procedures aimed at ensuring quality and mitigating risks associated with each new methodology. The work performed by the areas responsible for models is assessed by the Operational Risk and Internal Audit teams to ensure adherence to these policies. Opportunities for improvement identified throughout these assessments are properly addressed through action plans, which are monitored by the three lines and senior management until their completion. Independent Validation of Risk Models Itaú Unibanco performs independent validation of its risk processes and risk models. This activity is carried out by a department that is segregated from both the business areas and the risk control areas, ensuring independence in the assessments. The validation methodology, defined in a specific internal policy, complies with regulatory requirements, such as those established in BACEN Circulars 303, 3,646, 3,674, 3,876 and Resolutions 4,966, 4,277, and 4,557. The validation stages include, among others: 1. Verification of the technical soundness and assumptions used in the models; 2. Qualitative and quantitative analysis of the models, including variable declaration, development of an independent calculator, and assessment of the adequacy of the technical references used; 3. When applicable, comparison with alternative models and external benchmarks; 4. Historical backtesting of the model; 5. Assessment of the adequacy of the model implementation in the systems used. Additionally, the validation area evaluates the stress testing program. The work performed by the independent validation area, as well as the validations of processes and models, is assessed by Internal Audit and submitted to specific committees composed of senior management members. Opportunities for improvement identified throughout the independent validation process are addressed through action plans, which are monitored by the three lines and senior management until their completion.
Risk and Capital Management - Pillar 3 __________________________________________________________________________________________ __________________________________________________________________________________________ Itaú Unibanco 62 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, 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;
Risk and Capital Management - Pillar 3 __________________________________________________________________________________________ __________________________________________________________________________________________ Itaú Unibanco 63 • 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", "Policies", "Corporate Policy for the Prevention of Unlawful Acts". Additionally, Itaú Unibanco has been developing several data analytics models to enhance its customer risk classification methodology, transaction monitoring, and KYC processes, with a focus on increasing analytical accuracy, reducing false positives, and strengthening an integrated risk view. Itaú Unibanco has also been innovating its modeling solutions through the use of advanced machine learning and Artificial Intelligence techniques, including Generative AI, enabling greater correlation across multiple information sources, improved timeliness in analyses and investigations, more efficient alert prioritization, and qualified support for decision- making, resulting in AML processes that are more robust, efficient, and aligned with regulatory best practices. Cyber Risk Cyber risks refer to events that may cause financial losses, operational disruptions, data extraction, or damage to information stored in our systems. These risks may arise from intrusions by malicious individuals, infiltration of malware (such as computer viruses), intentional or accidental contamination of our networks and systems by third parties with whom we exchange information, exploitation of vulnerabilities, unauthorized access to confidential customer data and/or proprietary information by individuals inside or outside the Organization, as well as cyberattacks that compromise the availability of our services and the integrity of our information. Itaú Unibanco is committed to protecting corporate information and ensuring the privacy of customers and the general public in all operations. To achieve this, we adopt strict control processes focused on detecting, preventing, continuously monitoring, and responding immediately to threats and intrusion attempts into our infrastructure. These actions ensure effective risk management, support digital transformation, and are aligned with key regulators, external audits, market best practices, and certifications. As part of this strategy, we have adopted the concept of expanded perimeter protection, which considers that information must be protected wherever it resides: within the bank’s infrastructure, in a cloud service provided by a third party, or in an international unit. This approach covers the entire information lifecycle — from collection, through processing, transmission, storage, analysis, and ultimately, destruction. The area responsible for this strategy is the Cyber Security Department, created to address the challenge of protecting the bank in an increasingly digital, complex, and constantly evolving environment. The Corporate Information Security and Cyber Security Policy is available at www.itau.com.br/relacoes-com- investidores, under the sections “Itaú Unibanco” > “Corporate Governance” > “Policies” > “Corporate Information Security and Cyber Security Policy”.
Risk and Capital Management - Pillar 3 __________________________________________________________________________________________ __________________________________________________________________________________________ Itaú Unibanco 64 Crisis Management and Operational Resilience Itaú Unibanco's Operational Resilience 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.To this end, it has policies that establish procedures, roles and responsibilities to be followed by the areas of Itaú Unibanco. The Program establishes the Business Continuity Plan (BCP), which consists of modular procedures that are available for use in the event of incidents.In order for the recovery to take place quickly and safely, PCN has defined corporate and customized actions for its business lines. In order for the BCP to reflect the priorities for resuming the business environment that supports the delivery of products and services, BIA (Business Impact Analysis) is applied. BIA identifies and assesses the impact on the business of process interruptions caused by failures due to human, natural, climatic, environmental, social and/or technological risks. Considering the dependence that some processes have on third-party services, the Operational Resilience Program conducts an assessment of the risk of unavailability of services provided with a view to resilience to threats of interruption. To assess the efficiency and identify points for improvement in contingency actions, contingency plan exercises are carried out throughout the year. The frequency of the exercises is established by the plan manager and can be: annual, biannual or shorter (bimonthly, quarterly, monthly, etc.), taking into account the criticality of the process or the complexity of the contingency. The Program establishes a frequent flow of acculturation with the company's senior management, as well as a constant analysis of high-impact scenarios and events to establish response plans in line with current threats. To assess efficiency and identify points for improvement in crisis response plans, tests are carried out at least once a year. 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. Business and Strategy Risk Business and Strategic Risk is the risk arising from a negative impact on earnings and capital resulting from flawed strategic planning, adverse strategic decisions, Itaú Unibanco’s inability to implement appropriate strategic plans, and/or changes in its business environment. Itaú Unibanco has implemented several mechanisms to ensure that both business and strategic decision-making processes follow appropriate governance standards, involve the active participation of senior executives and the
Risk and Capital Management - Pillar 3 __________________________________________________________________________________________ __________________________________________________________________________________________ Itaú Unibanco 65 Board of Directors, are based on market, macroeconomic, and risk information, and aim to optimize the risk-return relationship. Strategic and business decisions and guidelines are established with the full involvement of the Board of Directors, particularly through the Strategy Committee, and senior executive management through the Executive Committee. To adequately address this risk, Itaú Unibanco maintains governance structures and processes that involve the Risk function in business and strategic decisions, seeking to ensure that risks are properly managed and that decisions remain sustainable over the long term. These include: (i) qualification and incentive structures for board members and executives; (ii) the budgeting process; (iii) product assessment and approval processes; (iv) evaluation and assessment of proprietary mergers and acquisitions opportunities; and (v) the risk appetite framework, which restricts, for example, credit concentrations and exposure to relevant and specific risks. Step-in Risk Step-in 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 step-in risk, (ii) the assessment of risks in relationships, (iii) the monitoring, control and mitigation of step-in risk, (iv) the assessment of impact on capital and liquidity and (v) reports. It is part of the scope of Step-in Risk governance: Related Party audiences, mainly composed of controllers (individuals and legal entities), entities related to them and controlled and related entities (as defined in Res. 4,693/18), foundations, investments in non-consolidated entities, suppliers of critical products and services, assigness, buyers and sellers of relevant assets, third parties with products distributed by Itaú Unibanco and third parties to whom Itaú Unibanco distributes products, besides all the analysis of the international Units. Emerging Risks These are newly identified risks that have a potentially material impact on business in the medium and long term, but for which there is still insufficient information for a complete assessment, due to the number of factors and impacts not yet fully understood, as they have no precedent and, therefore, have never been addressed in the past. Their causes may originate from external events, leading to the rise of new risks or the intensification of risks already monitored by ITAÚ UNIBANCO HOLDING. Once identified, such risks begin to be monitored and reassessed annually or on demand, until they no longer represent a risk or until they can be adequately measured. In the latter case, they then follow the subsequent stages of risk management. This process is ensured by the governance of ITAÚ UNIBANCO HOLDING, allowing these risks to also be incorporated into risk management procedures. Examples include Geopolitical, Climate, and CyberSecurity risks, which have or have had aspects considered as emerging risks.
