Management Report
Dear Shareholders:
We present the Performance Commentary on the Condensed Consolidated Financial Statements of Banco Santander (Brasil) S.A. (Banco Santander or the Bank) for the period ended March 31, 2026, prepared in accordance with International Financial Reporting Standards (IFRS) issued by the International Accounting Standards Board (IASB) and the interpretations of the IFRS Interpretation Committee (current name of the International Financial Reporting Interpretations Committee (IFRIC).
The Consolidated Financial Statements prepared in accordance with the international accounting standard issued by the International Accounting Standards Board (IASB) for the quarter ended March 31, 2026, will be published on April 29, 2026, at www.santander.com.br/ri.
Economic Situation
The economic performance was highlighted by the following themes:
In the international environment
v The global economy remains resilient, but is experiencing a supply shock and increased uncertainty.
The global economy began 2026 with greater resilience than expected, with activity still positive in major economies and relatively tight labor markets, although at a less robust pace than in 2025. This initial performance supported the reading of a gradual slowdown, with the United States, China, and the euro area maintaining positive growth, albeit heterogeneously. Throughout Q1 2026, however, the global environment changed. The escalation of the conflict in the Middle East generated a new energy shock, putting pressure on commodities, logistics costs, and current inflation, in addition to increasing financial volatility and trade uncertainty. As a result, the balance of risks for global growth deteriorated, while the disinflation trajectory began to appear less linear, especially in advanced economies. The shock reignited the dilemma for central banks between lower growth and higher inflation, leading the IMF to signal downward revisions to global growth in 2026.
v Oil at the heart of global macro dynamics
The main driver of the first quarter of 2026 was the intensification of the conflict in the Middle East, especially the direct involvement of Iran, which resulted in a significant shock to the global energy market. The disruption in the Strait of Hormuz—a strategic route for about 20% of the world's oil—significantly increased the perceived risk to global supply, placing oil back at the center of international macroeconomic dynamics. In this context, Brent crude accumulated a gain of over 35% during the year, prompting warnings from multilateral organizations about the risk of more prolonged supply constraints and persistent inflationary effects. The rise in oil prices began to put pressure on current inflation, contaminate expectations, reduce real income, and weaken activity, especially in energy-importing economies. The shock reintroduced an adverse supply component at a time when some advanced economies were approaching the end of disinflation, reigniting the growth-inflation dilemma faced by central banks.
v Central banks adopt a more cautious stance in the face of the energy shock.
In the field of monetary policy, the quarter was marked by greater caution from major central banks. The Federal Reserve kept its benchmark interest rate unchanged at its January and March meetings, maintaining a data-dependent stance in an environment of inflation still above target. Throughout the quarter, the Fed began to signal a less benign inflationary scenario, with higher inflation projections and less conviction regarding the eventual resumption of the rate-cutting cycle, especially after the energy shock, which added new upside risks to the scenario. The European Central Bank also kept interest rates stable and explicitly acknowledged that the escalation of the conflict in the Middle East should put pressure on inflation in the short term via energy. Overall, the global environment remained in a holding pattern: the trajectory of interest rates began to incorporate greater uncertainty in the face of an adverse supply shock.
In the home environment
The Brazilian economy is set to accelerate again in early 2026 with pockets of resilience and renewed momentum.
The Brazilian economy began 2026 in a cyclical recovery process after losing momentum in the second half of 2025. GDP in Q4 2025 advanced only 0.1% quarter-on-quarter, the second consecutive quarter of near-stagnation. However, high-frequency indicators for Q1 2026 painted a net positive picture. While the labor market remained relatively tight, consistent with significant real wage gains, it is worth highlighting the beginning of the effects of the income tax exemption for individuals, which permanently increases the disposable income of eligible families.
v The improvement in inflation was interrupted.
The turn of the year brought more favorable signs for inflation, with the IPCA (Brazilian consumer price index) over 12 months falling from 4.3% in 2025 to 3.8% by February, still above the 3% target, benefiting from currency appreciation and moderation in food prices.. However, this scenario reversed in March, when the IPCA registered a higher-than-expected increase, raising 12-month inflation to 4.1%. This movement mainly reflected strong pressure from fuel and food prices, in line with the domestic transmission of the external energy shock resulting from the war in the Middle East. Despite this, the core inflation reading remained more subdued than the headline index, indicating that underlying disinflation has not yet been fully reversed. The quarter thus highlighted an environment of more pressured current inflation and greater uncertainty regarding the speed of convergence to the target.
v Copom begins easing restrictions, but with greater caution and more limited room for cuts.
The main monetary policy event of the quarter was the start of the Selic rate reduction cycle, in a more adverse context than previously anticipated. In January, the Copom (Monetary Policy Committee) maintained the rate at 15.00% per year and signaled easing for the following meeting. In March, it implemented the first cut since May 2024, reducing the Selic rate to 14.75%, in a 25 bps adjustment—below the prevailing pricing before the escalation of the conflict in the Middle East. The Central Bank characterized the move as a calibration cycle, reflecting the worsening of the risk balance associated with the external energy shock. In the baseline scenario, the inflation projection for 2026 was raised to 3.9%, reinforcing the message that the cycle has begun, but with greater caution, less conviction regarding its extent, and enhanced vigilance over expectations and secondary pass-throughs.
Consolidated Performance
In 1Q26, we maintained our focus on executing our strategy, with the ambition of becoming the leading financial platform in our customers’ lives. We continue to make consistent progress in building an increasingly diversified, resilient and profitable operation, well positioned for sustainable long-term growth.
We closed the quarter with a net profit of BRL 3.8 billion, representing a decline of 7.3% QoQ and 1.9% YoY. Return on equity reached 16.0%, down 1.6 p.p. QoQ and 1.5 p.p. compared to the same period of 2025.
Total revenues increased 0.8% QoQ and 0.9% YoY. Net interest income rose 3.1% QoQ and declined 0.7% YoY. On a quarterly basis, performance was mainly driven by an improvement in market NII, reflecting lower negative sensitivity to interest rates, lower number of business days, and improved treasury results. On an annual basis, the decline reflects the negative interest rate sensitivity and lower treasury results, weighing on market NII results. Client NII declined 1.4% QoQ and increased 4.8% YoY. QoQ performance reflects fewer calendar and business days, while yearly growth was mainly driven by volume, mix and pricing discipline, contributing to spread expansion.
Fees delivered solid annual performance, increasing 5.8% YoY, supported by revenue diversification, with a more balanced contribution between credit and services, and remaining a key growth pillar. Highlights include cards (+9.8%) and insurance (+12.2%). On a quarterly basis, fees declined 5.5%, reflecting typical seasonality, particularly in cards.
The expanded loan portfolio declined 0.4% QoQ and increased 3.4% YoY, totaling BRL 705,582 million. The quarterly decline was mainly driven by seasonality in cards and FX effects. Over twelve months, growth was led by consumer finance (+14.2%), while in Individuals, mortgages (+10.6%) and cards (+9.1%) stood out, and SMEs grew 9.9% YoY. We maintain a disciplined approach to capital allocation, focused on strategic businesses, portfolio risk management and profitability.
Total funding reached BRL 743,309 million, increasing 0.6% QoQ and 2.8% YoY, maintaining our focus on a more balanced mix between Individuals and Corporate, with Individuals now representing 51% of total funding (+6 p.p. YoY).
The result from loan losses totaled BRL 6,344 million, increasing 3.9% QoQ and declining 0.7% YoY. On a quarterly basis, provisions remained pressured by the macroeconomic environment and elevated household indebtedness, while the annual decline reflects active risk management and portfolio mix effects.
Expenses remained under strict control, stable QoQ and increasing 0.9% YoY, well below inflation. We remain committed to efficient cost management and the use of technology to optimize processes and maximize productivity.
We are focused on delivering sustainable long-term results through a solid and diversified balance sheet, driven by an unwavering emphasis on excellence in customer experience

Sustainability
Our journey in sustainability began more than 20 years ago. Throughout this semester, we have experienced an intense evolution, in which we have improved our programs, business, and governance related to this topic.
Throughout this journey, key aspects include the assessment and mitigation of social, environmental, and climate risks for granting credit to projects and companies; the generation of businesses that support clients' transition to a low-carbon economy; and the building of a more inclusive society through education and employability initiatives, financial inclusion and entrepreneurship, and social inclusion. Many of these initiatives are accompanied by global goals in areas where we have the greatest potential impact, such as net zero, financial inclusion, and inclusive culture.
To ensure good governance of this process, we rely on robust policies and controls, supported by senior leadership.
In Q1 2026, we highlight the following results:
Sustainable business
v We have enabled R$ 10.8 billion in sustainable business deals, according to our sustainable finance and investment rating system (SFICS), reaching a total of R$ 52.4 billion in the sustainable credit portfolio, with growth of 30% YoY.
v We maintained our market leadership in CBIOS (carbon credits) with 38% market share.
The Prospera Santander Microfinanças program, which provides financial solutions to entrepreneurs, achieved a microcredit output of R$ 1.27 billion (3% YoY). The total portfolio grew by 9% YoY, reaching R$ 3.53 billion, with a total customer base of 1.2 million.
v Also noteworthy is the issuance of R$200 million in debentures to OLEOPLAN S.A. - ÓLEOS VEGETAIS PLANALTO, using resources from EcoInvest, a Brazilian government program for mobilizing foreign private capital and providing exchange rate protection, created to facilitate the attraction of foreign private investment for the country's ecological transformation. The funds will be used for the modernization and expansion of two biodiesel production plants.

The Santander Integrated Social Project provided educational and cultural activities in 30 municipalities, in addition to training programs for local micro-entrepreneurs, in partnership with Prospera.
Education, employability and entrepreneurship
We highlight two initiatives focused on education and digital inclusion: the Santander Open Academy, a global platform offering courses, scholarships, and international career development opportunities, and the Digital Campus, a solution that supports the digitalization of universities through an application that creates a secure digital identity and integrates students, professors, and academic services. Together, these initiatives have benefited approximately 145,000 people, with an investment of 2.9 million in the community.

Independent Audit
The policy of Banco Santander, including its subsidiaries, regarding the contracting of services unrelated to the audit of Financial Statements by its independent auditors PricewaterhouseCoopers, is based on Brazilian and international auditing standards, which preserve the auditor's independence.

1.Operating context, presentation of consolidated condensed financial statements and other information
a)Operational Context
Banco Santander (Brasil) S.A. (Banco Santander or Bank), controlled directly and indirectly by Banco Santander, S.A., with headquarters in Spain (Banco Santander Spain), is the leading institution of the Financial and Prudential Conglomerates before the Central Bank of Brazil (Bacen), constituted as a joint-stock company, with headquarters at Avenida Presidente Juscelino Kubitschek, 2041 e 2235 - Bloco A - Vila Olímpia - São Paulo - SP. Banco Santander operates as a multiple bank and carries out its operations through commercial, investment, credit, financing and investment, real estate credit, leasing and foreign exchange portfolios. Through controlled companies, it also operates in the payment institution, consortium management, securities brokerage, insurance brokerage, consumer financing, digital platforms, benefits management, management and recovery of non-performing credit, capitalization and private pension markets, and provision and administration of food, meal and other vouchers. Operations are conducted in the context of a group of institutions that operate integrated in the financial market. The benefits and costs corresponding to the services provided are absorbed between them and are realized in the normal course of business and under commutative conditions.
The Board of Directors has authorized the issuance of the consolidated condensed interim financial statements for the period ended March 31, 2026, at the meeting held on April 29, 2026.
The aforementioned Financial Statements were subject to a recommendation for approval issued by Banco Santander's Audit Committee.
b)Presentation of Consolidated Condensed Interim Financial Statements (prepared in accordance with IAS 34)
The Consolidated Financial Statements were prepared in accordance with the International Financial Reporting Standards (IFRS®) issued by the International Accounting Standards Board (IASB®) (currently referred to by the IFRS® Foundation as “IFRS® accounting standards”) and the interpretations issued by the IFRS® Interpretations Committee (current name of the International Financial Reporting Interpretations Committee – IFRIC®). All relevant information specifically related to the Financial Statements of Banco Santander, and only in relation to these, is being disclosed and corresponds to the information used by Banco Santander in its management. There is no change in applicable practices and policies between the consolidated Condensed Financial Statements and the complete financial statements which are published on the RI website, with the database as of 12/31/2025.
c)Other Information
c.1)Adoption of new standards and interpretations
· Amendment to IAS 21 – Effects of Changes in Exchange Rates and Translation of Financial Statements: If a currency is not convertible, it may be difficult to determine an appropriate exchange rate. Although uncommon, a lack of convertibility may arise when a government imposes exchange controls that prohibit the exchange of a currency or limit the volume of transactions in a foreign currency. The amendment to IAS 21 clarifies how entities should assess whether a currency is easily convertible and how they should determine a spot exchange rate for a currency that is difficult to convert, as well as requiring disclosure of information that allows users of financial statements to understand the impacts of a currency that is not convertible. These amendments are effective from January 1, 2025. Santander did not identify any material impacts.
c.2)New standards and interpretations in force in future years
· Amendments to IFRS 9 and IFRS 7 - Amendments to the Classification and Measurement of Financial Instruments: The requirements for applying IFRS 9 are amended to include contracts to purchase and receive electricity, in addition to allowing the use of these contracts in hedge accounting. It also includes disclosure requirements on these contracts in IFRS 7. In addition, it clarifies that a financial liability is derecognized on the "settlement date" and introduces an accounting policy election to derecognize financial liabilities settled using an electronic payment system before the settlement date. Other clarifications include the classification of financial assets with ESG-linked characteristics through additional guidance on the assessment of contingent characteristics. Additional disclosures are introduced for financial instruments with contingent characteristics and equity instruments classified at fair value through other comprehensive income. The amendments are effective for reporting periods beginning on or after January 1, 2026. These amendments did not impact our disclosures.
· Annual Improvements to IFRS Accounting Standards - Volume 11: They include clarifications, simplifications, corrections and amendments designed to improve the consistency of several IFRS Accounting Standards. The amended standards are: IFRS 1 - First-time adoption of International Financial Reporting Standards; IFRS 7 - Financial Instruments: Disclosures and accompanying guidance on the implementation of IFRS 7; IFRS 9 - Financial Instruments; IFRS 10 - Consolidated Financial Statements; and IAS 7 - Statement of Cash Flows. The amendments are effective for annual periods beginning on or after January 1, 2026, with earlier application permitted.
· IFRS 18 – Presentation and Disclosure in Financial Statements: Replaces IAS 1 – Presentation of Financial Statements. IFRS 18 introduces new subtotals and three categories for income and expenses (operating, investing and financing) in the income statement structure. It also requires companies to disclose explanations of management-defined performance measures related to the income statement.
These changes are effective for fiscal years beginning January 1, 2027. Santander is evaluating the impacts of this change.
· IFRS 19 – Non-publicly-accountable subsidiaries: Disclosures:that allows a subsidiary to provide reduced disclosures when applying IFRS Accounting Standards in its financial statements. IFRS 19 is optional for eligible subsidiaries and establishes the disclosure requirements for subsidiaries that choose to apply it. The new standard is effective for reporting periods beginning on or after January 1, 2027, with earlier application permitted. Santander is evaluating the impacts of this change
c.3)Estimates used
The consolidated results and the calculation of consolidated equity are impacted by accounting policies, assumptions, estimates and measurement methods used by the Bank's management in preparing the financial statements. The Bank makes estimates and assumptions that affect the reported amounts of assets and liabilities for future periods. All estimates and assumptions required, in accordance with IFRSs, are management's best estimate in accordance with the applicable standard.
In the consolidated financial statements, estimates are made by the Management of the Bank and the consolidated entities in order to quantify certain assets, liabilities, income and expenses and disclosures in the explanatory notes.
c.3.1)Critical estimates
The critical estimates and assumptions that have the most significant impact on the accounting balances of certain assets, liabilities, revenues and expenses and on the disclosures in the explanatory notes are described below:
i. Assessment of the fair value of certain financial instruments
Financial instruments are initially recognized at fair value and those that are not measured at fair value in profit or loss are adjusted for transaction costs.
Financial assets and liabilities are subsequently measured, at the end of each period, using valuation techniques. This calculation is based on assumptions, which take into account Management's judgment based on information and market conditions existing at the balance sheet date.
Banco Santander classifies fair value measurements using the fair value hierarchy that reflects the model used in the measurement process, segregating financial instruments into Levels I, II or III.
Note 18.c of the Consolidated Condensed Financial Statements as of March 31, 2026, presents the accounting practice and sensitivity analysis for the Financial Instruments, respectively.
ii. Provisions for losses on credits due to impairment
The carrying value of non-recoverable financial assets is adjusted by recording a provision for loss under “Losses on financial assets (net) – Financial Assets measured at amortized cost” in the consolidated income statement. The reversal of previously recorded losses is recognized in the consolidated income statement in the period in which the impairment decreases and can be objectively related to a recovery event.
To individually measure the loss due to impairment of loans assessed for impairment, the Bank considers the conditions of the counterparty, such as its economic and financial situation, level of indebtedness, income generating capacity, cash flow, administration, corporate governance and quality of internal controls, payment history, experience in the sector, contingencies and credit limits, as well as characteristics of assets, such as their nature and purpose, type, sufficiency and guarantees of liquidity level and total credit value , and also based on historical experience of impairment and other circumstances known at the time of the assessment.
To measure the loss due to impairment of loans assessed collectively for impairment, the Bank separates financial assets into groups taking into account the characteristics and similarities of credit risk, that is, according to the segment, type of assets, guarantees and other factors associated with historical experience of impairment and other circumstances known at the time of the assessment.
iii. Provisions for pension funds
Defined benefit plans are recorded based on an actuarial study, carried out annually by a specialized company, at the end of each year, effective for the subsequent period and are recognized in the consolidated income statement in the lines Interest and similar expenses and Provisions (liquids).
The present value of a defined benefit obligation is the present value, without deducting any plan assets, of the expected future payments necessary to settle the obligation resulting from the employee's service in the current and past periods.
iv. Obligations, contingent assets and liabilities
Provisions for judicial and administrative proceedings are set up when the risk of loss of the judicial or administrative action is assessed as probable and the amounts involved can be measured with sufficient certainty, based on the nature, complexity and history of the actions and the opinion of legal advisors. internal and external.
v. Goodwill
The recorded goodwill is subject to the recoverability test, at least once a year or in a shorter period, in the case of any indication of a reduction in the recoverable value of the asset.
The basis used for the recoverability test is the value in use and, for this purpose, the cash flow is estimated for a minimum period of 5 years. The cash flow was prepared considering several factors, such as: (i) macroeconomic projections of interest rates, inflation, exchange rates and others; (ii) behavior and growth estimates of the national financial system; (iii) increase in costs, returns, synergies and investment plan; (iv) client behavior; and (v) growth rate and adjustments applied to flows in perpetuity. The adoption of these estimates involves the probability of future events occurring and changing any of these factors could have a different result. The cash flow estimate is based on an assessment prepared by an independent specialized company, annually or whenever there is evidence of a reduction in its recovery value, which is reviewed and approved by Management.
vi. Expectation of realization of IR and CS tax credits
Deferred tax assets and liabilities include temporary differences, identified as the amounts expected to be recovered or paid on differences between the carrying amounts of assets and liabilities and their respective calculation bases, and accumulated tax loss credits and the negative basis of CSLL. These amounts are measured at the rates expected to apply in the period in which the asset is realized or the liability is settled. Deferred tax assets are only recognized for temporary differences to the extent that it is considered probable that the consolidated entities will have sufficient future taxable profits against which the deferred tax assets can be used.
Other deferred tax assets (accumulated tax loss credits) are only recognized if it is considered probable that the consolidated entities will have sufficient future taxable profits to allow them to be used. The recognized deferred tax assets and liabilities are reviewed at each balance sheet date, with the appropriate adjustments being made based on the findings of the analyses performed. The expectation of realization of the Bank's deferred tax assets is based on projections of future results and a technical study.
c.4) Change of business Strategy
In the first quarter of 2025, Banco Santander changed the way it manages part of its portfolio of pre-and post-fixed government securities, financial instruments that are part of its portfolio called ALCO (assets and liability management). The new strategy is based on a long-term investment profile, aiming to ensure greater financial stability, avoiding volatility in the Bank's equity (including for prudential purposes). In accordance with this strategy, Banco Santander has the intention and capacity to hold these securities until their respective maturities.
Management adopted the Amortized Cost (AC) accounting classification for part of the ALCO portfolio, which better reflects the objective of the business model strategy, see note 3.a.

(1) On March 31, 2026, the balance recorded in “Loans and advances to customers” referring to operations of the assigned credit portfolio is R$16,000 (12/31/2025 – R$16,768).
(2) In the 2nd quarter of 2025, a portion of securities in the ALCO portfolio, in the amount equivalent to R$ 23,190 million, was classified in the category of Financial Assets measured at amortized cost (note 1.c.4), generating a reversal of mark-to-market adjustments on the reclassified securities, positively impacting shareholders' equity by R$ 514 million, net of tax effects (R$ 934 million gross) at the time.
b)Valuation adjustments arising from loss of recoverable value of financial assets
b.1)Financial assets measured at fair value through Other Comprehensive Income
As indicated in explanatory note 2 to the Bank's consolidated Interim Financial Statements for the period ended March 31, 2026, variations in the carrying value of financial assets and liabilities are recognized in the consolidated income statement and except in the case of financial assets measured at fair value through other comprehensive income, where changes in fair value are temporarily recognized in consolidated Net Equity, in “Other comprehensive income”.
Debits or credits in "Other Comprehensive Income" arising from changes in fair value remain in the Bank's consolidated Net Equity until the respective assets are written off, when they are then recognized in the consolidated income statement. As part of the fair value measurement process, when there is evidence of losses in the recoverable value of these instruments, the amounts are no longer recognized in Net Equity under the heading "Financial Assets Measured at Fair Value through Other Comprehensive Income” and are reclassified to the Consolidated Income Statement at the cumulative value on that date.
On March 31, 2026, the Bank analyzed the variations in the fair value of the various assets that make up this portfolio and concluded that, on that date, there were no significant differences whose origin could be considered as resulting from impairment losses. Consequently, all changes in the fair value of these assets are presented in “Other Comprehensive Income”. Changes in the balance of other comprehensive income in the interim period are recognized in the consolidated statement of Other Comprehensive Income.
b.2)Financial Assets Measured at Amortized Cost - Loans, other amounts with credit institutions, advances to customers and debt instrument

| Balance at end of the period | 51,847,129 | 42,847,771 | |||||||||||||||
d)Provisions for Losses of Financial Guarantee Contracts Provided

Below is the movement of these provisions for the periods ended March 31, 2026 and 2025.
| 01/01 to | 01/01 to | |||||||

7.Intangible assets - Goodwill
The goodwill constitutes the excess between the acquisition cost and the Bank's share in the net fair value of the acquiree's assets, liabilities and contingent liabilities. When the excess is negative (discount), it is recognized immediately in profit or loss. In accordance with IFRS 3 Business Combinations, goodwill is carried at cost and is not amortized, but tested annually for impairment purposes or whenever there is evidence of impairment of the cash-generating unit to which it was allocated. Goodwill is recorded at its cost value less accumulated impairment losses. Impairment losses recognized on goodwill are not reversed. Gains and losses on the disposal of an entity include the carrying value of the goodwill related to the entity sold.
The recorded goodwill is subject to the recoverability test (note 1.c.3.1.v) and was allocated according to the operating segment (note 15).
During the period, no indications of impairment of goodwill were identified.

A quantitative goodwill recoverability test is performed annually.
For the goodwill recognized on the acquisition of Banco Real and Olé, as detailed in the tables above, an analysis is carried out at the end of each year as to whether there is any evidence of impairment. In the period ended March 31, 2026 and fiscal year 2025 there was no evidence of impairment. In the goodwill impairment test, discount rates and growth over perpetuity are the most sensitive assumptions for calculating the present value (value in use) of discounted future cash flows.

b) Tax, Social Security, Labor and Civil Provisions
Banco Santander and its subsidiaries are an integral part of legal and administrative proceedings of a tax, social security, labor and civil nature, arising in the normal course of their activities.
The provisions were constituted based on the nature, complexity and history of the actions and the loss assessment of the companies' actions based on the opinions of internal and external legal advisors. Banco Santander's policy is to fully provision the value at risk of shares whose assessment is probable loss.
Management understands that the provisions set up are sufficient to cover possible losses arising from legal and administrative proceedings as follows:
b.1)Judicial and Administrative Proceedings of a Tax and Social Security Nature
Main judicial and administrative proceedings with probable risk of loss
Banco Santander and its controlled companies are parties to legal and administrative proceedings related to tax and social security discussions, which are classified based on the opinion of legal advisors, as risk of probable loss.
Provisional Contribution on Financial Transactions (CPMF) in Customer Operations - In May 2003, the Brazilian Federal Revenue Service issued an infraction notice to Santander Distribuidora de Títulos e Valores Mobiliários Ltda. (Santander DTVM) and another notice to Banco Santander (Brasil) S.A. The subject of the notices was the collection of CPMF on operations carried out by Santander DTVM in the management of its clients' resources and clearing services provided by the Bank to Santander DTVM, which occurred during the years 2000, 2001, and 2002. The administrative process ended unfavorably for both companies. On July 3, 2015, the Bank and Santander Brasil Tecnologia S.A. (current name of Produban Serviços de Informática S.A. and Santander DTVM) filed a lawsuit seeking to annul both tax debts. The aforementioned action resulted in a judgment and ruling of dismissal, which led to the filing of a Special Appeal to the Superior Court of Justice (STJ) and an Extraordinary Appeal to the Supreme Federal Court (STF). The cases related to the CPMF (Provisional Contribution on Financial Transactions) in Client Operations were subject to adherence to the Comprehensive Transaction Program (PTI), established by the Ministry of Finance. In December 2025, the amounts paid, totaling R$ 1,067 million established in the transaction, were fully provisioned.
National Social Security Institute (INSS) - R$ $167 million (31/12/2025 - R$ 167 million in Consolidated): Banco Santander and its controlled companies are administratively and judicially disputing the collection of social security contributions and education salary on various payments that, according to legal advisors, are not considered salary.
Service Tax (ISS) - Financial Institutions - R$ 352 million(31/12/2025 - R$ 335 million in Consolidated): The Bank and its controlled companies are administratively and judicially disputing the requirement, by several municipalities, to pay ISS on various revenues arising from operations that are not usually classified as the provision of services. In addition, other actions involving ISS, classified as a possible loss risk, are described in Note 10.b.4.
b.2)Judicial and Administrative Proceedings of a Labor Nature
These are actions filed by Unions, Associations, the Public Ministry of Labor and former employees claiming labor rights that they believe are due, in particular the payment of “overtime” and other labor rights, including processes related to retirement benefits.
For lawsuits considered common and similar in nature, provisions are recorded based on the historical average of closed lawsuits. Actions that do not meet the previous criteria are provisioned in accordance with an individual assessment carried out, with provisions being constituted based on the probable risk of loss, the law and jurisprudence in accordance with the loss assessment carried out by legal advisors.
b.3)Judicial and Administrative Proceedings of a Civil Nature
These provisions generally arise from: (1) actions requesting a review of contractual terms and conditions or requests for monetary adjustments, including alleged effects of the implementation of various government economic plans, (2) actions arising from financing contracts, (3) enforcement actions; and (4) actions for compensation for losses and damages. For civil actions considered common and similar in nature, provisions are recorded based on the historical average of closed cases. Claims that do not meet the previous criteria are provisioned in accordance with an individual assessment carried out, with provisions being constituted based on the probable risk of loss, the law and jurisprudence in accordance with the loss assessment carried out by legal advisors.
The main processes classified as probable loss risk are described below:
Compensation Suits - Refer to compensation for material and/or moral damage, relating to the consumer relationship, mainly dealing with issues relating to credit cards, direct consumer credit, current accounts, billing and loans and other matters. In actions relating to causes considered similar and usual for the business, in the normal course of the Bank's activities, the provision is constituted based on the historical average of closed processes. Actions that do not meet the previous criteria are provisioned in accordance with an individual assessment carried out, with provisions being constituted based on the probable risk of loss, the law and jurisprudence in accordance with the loss assessment carried out by legal advisors.
Economic Plans - They refer to judicial discussions, which plead alleged inflationary purges resulting from Economic Plans (Bresser, Verão, Collor I and II), as they understand that such plans violated acquired rights related to the application of inflationary indices supposedly due to Savings Accounts, Judicial Deposits and Term Deposits (CDBs). The actions are provisioned based on the individual assessment of loss carried out by legal advisors.
Banco Santander is also a party to public civil actions on the same matter, filed by consumer protection entities, the Public Prosecutor's Office or Public Defenders' Offices. The constitution of a provision is only made for cases with probable risk, based on requests for individual executions. The issue is still under analysis by the STF. There is jurisprudence in the STF favorable to Banks in relation to an economic phenomenon similar to that of savings, as in the case of correction of time deposits (CDBs) and corrections applied to contracts (table).
On April 14, 2010, the Superior Court of Justice (STJ) decided that the deadline for filing public civil actions discussing the purges is 5 years from the date of the plans, but this decision has not yet become final. Therefore, with this decision, most of the actions, as proposed after the 5-year period, will probably be judged unfounded, reducing the amounts involved. The STJ also decided that the deadline for individual savers to qualify for Public Civil Actions is also 5 years, counting from the final judgment of the respective sentence. Banco Santander believes in the success of the theses defended before these courts due to their content and foundation.
At the end of 2017, the Federal Attorney General's Office (AGU), Bacen, the Consumer Protection Institute (Idec), the Brazilian Savers Front (Febrapo) and the Brazilian Federation of Banks (Febraban) signed an agreement that seeks to end the legal disputes over Economic Plans.
The discussions focused on defining the amount that would be paid to each author, according to the balance in the book on the date of the plan. The total value of payments will depend on the number of subscriptions, and also on the number of savers who have proven in court the existence of the account and the balance on the anniversary date of the index change. The agreement negotiated between the parties was approved by the STF.
In a decision handed down by the STF, there was a national suspension of all processes dealing with the issue for the period of validity of the agreement, with the exception of cases in definitive compliance with a sentence.
On March 11, 2020, the agreement was extended by means of an addendum, with the inclusion of actions that only involve the discussion of the Collor I Plan. This extension has a term of 5 years and the approval of the terms of the addendum occurred on the 3rd June 2020.
In May 2025, there was a trial of the Claim of Non-Compliance with Fundamental Precept (ADPF) number 165 recognizing the constitutionality of the Bresser, Verão, Collor I and II plans and guaranteeing savers the receipt of the amounts established in the collective agreement and setting a period of 24 months for new savers to join.
Management considers that the provisions constituted are sufficient to cover the risks involved with the economic plans, considering the approved agreement.
b.4)Contingent Tax, Social Security, Labor, and Civil Liabilities Classified as Possible Risk of Loss
These are judicial and administrative proceedings of a tax and social security, labor and civil nature classified, based on the opinion of legal advisors, as a possible risk of loss, and are therefore not provisioned.
Tax actions classified as possible loss totaled R$ 36,916 million in Consolidated (12/31/2025 - R$ 37,518 million in Consolidated), with the main processes being as follows:
PIS and COFINS - Legal actions brought by Banco Santander (Brasil) S.A. and other entities of the Group to rule out the application of Law No. 9.718/98, which changes the calculation basis of the Social Integration Program (PIS) and the Contribution for Social Security Financing (COFINS), extending it to all entities' revenues, and not just revenues arising from the provision of services. In relation to the Banco Santander (Brasil) S.A. case, in 2015 the Federal Supreme Court (STF) admitted the extraordinary appeal filed by the Federal Union in relation to PIS, and dismissed the extraordinary appeal filed by the Federal Public Ministry in relation to the contribution to COFINS, confirming the decision of the Federal Regional Court in favor of Banco Santander (Brasil) S.A. in August 2007. The STF decided, through General Repercussion, Topic 372 and partially accepted the Federal Union's appeal, establishing the thesis that it applies PIS/COFINS on operating revenues arising from typical activities of financial institutions. With the publication of the ruling, the Bank presented a new appeal in relation to PIS, and is awaiting analysis. Based on the assessment of the legal advisors, the risk prognosis was classified as possible loss, with an outflow of appeal not being likely. As of March 31, 2026, the amount involved is R$ 2,382 million. For other legal actions, the respective PIS and COFINS obligations were established.
INSS on Profit Sharing or Results (PLR) - The Bank and its controlled companies have legal and administrative proceedings arising from questions from the tax authorities, regarding the collection of social security contributions on payments made as a share in profits and results. On March 31, 2026, the value was approximately R$ 11,902 million.
Service Tax (ISS) - Financial Institutions - Banco Santander and its controlled companies are administratively and judicially discussing the requirement, by several municipalities, to pay ISS on various revenues arising from operations that are not usually classified as provision of services. On March 31, 2026, the value was approximately R$ 3,806 million.
Unapproved Compensation - The Bank and its affiliates discuss administratively and judicially with the Federal Revenue Service the non-approval of tax offsets with credits resulting from overpayment or undue payment. On March 31, 2026, the value was approximately R$ 6,193 million.
Losses in Credit Operations - the Bank and its controlled companies contested the tax assessments issued by the Brazilian Federal Revenue alleging the undue deduction of losses in credit operations from the IRPJ and CSLL calculation bases as they allegedly did not meet the requirements of applicable laws. On March 31, 2026, the value was approximately R$ 1,171 million.
Use of CSLL Tax Loss and Negative Base – Assessment notices drawn up by the Brazilian Federal Revenue Service in 2009 and 2019 for alleged undue compensation of tax losses and negative CSLL basis, as a consequence of tax assessments issued in previous periods. Judgment at the administrative level is awaited. On March 31, 2026, the value was approximately R$ 2,782 million.
Amortization of Goodwill from Banco Sudameris Acquisition - The tax authorities issued tax assessment notices to demand payment of IRPJ and CSLL, including late payment charges, related to the tax deduction of the amortization of the goodwill paid in the acquisition of Banco Sudameris, for the base period from 2007 to 2012. Banco Santander filed its respective administrative defenses. The first period assessed is awaiting analysis of an appeal at CARF. Regarding the period from 2009 to 2012, a lawsuit was filed to discuss the IRPJ portion, due to the unfavorable conclusion in the administrative proceeding. For the CSLL portion of this same period, we request the withdrawal of the Special Appeal filed, aiming to take advantage of the benefits established by Law No. 14,689/2023 (quality vote). Legal action was also taken for the remaining portion. On March 31, 2026, the amount was approximately R$ 848 million.
IRPJ and CSLL - Capital Gain - the Brazilian Federal Revenue Service issued a tax assessment notice against Santander Seguros (legal successor to ABN AMRO Brasil Dois Participações S.A. (AAB Dois Par) charging income tax and social contribution related to the 2005 fiscal year. The Brazilian Federal Revenue Service claims that the capital gain on the sale of shares in Real Seguros S.A. and Real Vida e Previdência S.A by AAB Dois Par should be taxed at a rate of 34.0% instead of 15.0%. The assessment was administratively challenged with. based on the understanding that the tax treatment adopted in the transaction was in accordance with current tax legislation and the capital gain was duly taxed. The Administrative process ended unfavorably to the Company. In July 2020, the Company filed a lawsuit seeking to cancel the debt. An unfavorable decision was made in the first instance, an appeal will be filed with the Court. Banco Santander is responsible for any adverse result in this process as former controller of Zurich Santander Brasil Seguros e Previdência S.A. On March 31, 2026, the amount was approximately R$ 731 million.
IRRF – Foreign Remittance – The Company filed a lawsuit seeking to eliminate the Withholding Income Tax – IRRF, on payments derived from the provision of technology services by companies based abroad, due to the existence of International Treaties signed between Brazil and Chile; Brazil-Mexico and Brazil-Spain, thus avoiding double taxation. A favorable sentence was given and there was an appeal by the National Treasury, to the Federal Regional Court of the 3rd Region, where it awaits judgment. On March 31, 2026, the value was approximately R$ 483 million.
Labor claims classified as possible loss totaled R$ 1,426 million and R$ 2,177 million respectively, in the consolidated figures.
11.Stockholders’ equity
a)Capital Stock
In accordance with the Bylaws, Banco Santander's Capital Stock may be increased up to the limit of the authorized capital, regardless of statutory reform, upon deliberation by the Board of Directors and through the issuance of up to 9,090,909,090 (nine billion, ninety million, nine hundred and nine thousand and ninety) shares, observing the legal limits established regarding the number of preferred shares. Any capital increase exceeding this limit will require shareholder approval.
At the Ordinary General Meeting held on April 26, 2024, the increase in share capital in the amount of R$10,000,000,000.00 (ten billion reais) was approved, without the issuance of new shares, through the capitalization of part of the balance of the statutory profit reserve.

Global ILP (Long-Term Incentive) Plans
Currently, we have active global plans launched between 2019 and 2025, targeting global stocks and options, whose design includes:
•Clear definition of performance metrics (financial and non-financial);
•Multi-year deferral, ensuring focus on sustainable results;
•Settlement in assets or financial equivalents, in accordance with malus and clawback rules.
This structure aligns with international best practices in compensation governance, reinforcing transparency and capital discipline.
Pricing Model
The measurement of the plans is based on the Local Volatility (Dupire) model, adjusted to incorporate uncertainties in dividends, offering greater accuracy in the fair value estimate. The main parameters considered include:
•Weighted average share price;
•Exercise price;
•Implied and expected volatility;
•Risk-free interest rate;
•Dividend projection.
The options have expiration dates up to 2033, and the exercise price corresponds to the market value on the exercise date, conditional upon achieving the established targets.
Local ILP Plans (Long-Term Incentive)
Local long-term incentive plans may be granted in accordance with the strategy of new companies in the group or specific businesses, generally with a vesting period of 3 (three) years.
Each plan has a specific contract, and its calculation and payment must be approved by the established governance body, observing local and global regulatory resolutions.
Each participant's reference value will be converted into SANB11 shares, typically based on the price of the last 30 trading sessions of the month immediately preceding the plan payment.
At the end of the vesting period, payment, whether of the resulting shares in the case of local plans or of the value equivalent to the shares/options in the case of global plans, is made with a restriction of 1 (one) year, and this payment is still subject to the application of Malus/Clawback clauses, which may reduce or cancel the shares to be delivered in cases of non-compliance with internal rules and exposure to excessive risks, or in cases of material failure to comply with the requirements for financial reporting, in accordance with Section 10D of the Exchange Act (SEC), applicable to companies with shares listed on the NYSE.
a.1)Impact on the Result
The impacts on the result are recognized linearly during the vesting period under Personnel Expenses, as follows:
| Consolidated | ||||||||||||||||||||||||||
| 01/01 to | 01/01 to | |||||||||||||||||||||||||
| 03/31/2026 | 03/31/2025 | |||||||||||||||||||||||||

| Local | Santander Shares (Brazil) | 5,294 | 1,709 | |||||||||||||||||||||||
| Global | Global Stocks and Options | 938 | 1,677 | |||||||||||||||||||||||
a.2) Variable Remuneration Referenced to Shares
The long-term incentive plan (Deferral) determines the requirements for payment of future deferred installments of variable remuneration, considering the sustainable long-term financial bases, including the possibility of applying reductions or cancellations based on the risks assumed and fluctuations in the cost of capital.
Banco Santander's share-linked variable compensation plan is divided into 2 (two) programs: (i) Identified Group, which includes members of the Executive Committee, Statutory Directors, and other executives who assume significant and responsible risks in the control areas; and (ii) Other Employees, with variable compensation above the minimum amount established by policy. The deferral for both groups is 50% in cash indexed to 100% of the CDI rate and 50% in instruments. The impacts on the result are accounted for under Personnel Expenses, as follows:
| Program | Participant | Liquidity Type | 01/01 to | 01/01 to | |||||||||||||||||||||||||
| 03/31/2026 | 03/31/2025 | ||||||||||||||||||||||||||||
| Collective Identified | Members of the Executive Committee, Statutory Officers and other executives who assume significant and responsible risks of control areas | 50% in cash indexed to 100% of CDI and 50% in shares (Units SANB11) | 83,943 | 102,891 | |||||||||||||||||||||||||
| Unidentified Collective | Other employees with variable remuneration above a minimum expected value | 50% in cash indexed to 100% of the CDI and 50% instruments | 66,095 | 73,394 | |||||||||||||||||||||||||
15.Operating segments
According to IFRS 8, an operating segment is a component of an entity:
(a)That operates in activities from which it may obtain income and incur expenses (including income and expenses related to operations with other components of the same entity);
(b)Whose operating results are regularly reviewed by the entity's main person responsible for operational decisions related to the allocation of resources to the segment and the evaluation of its performance; It is
(c)For which distinct financial information is available.
Based on these guidelines, the Bank has identified the following reportable operating segments:
• Commercial Bank
• Global Wholesale Bank
The Bank has two segments, the commercial segment that includes individuals and legal entities (except for global corporate clients, which are treated in the Global Wholesale Banking segment) and the Global Wholesale Banking segment, which includes Investment Banking and Markets, including treasury and equity trading departments.
The Bank operates in Brazil and abroad, through the Cayman and Luxembourg branches, with Brazilian clients and, therefore, does not have geographic segmentation.

17.Value of financial assets and liabilities
According to IFRS 13, the measurement of fair value using a fair value hierarchy that reflects the model used in the measurement process must be in accordance with the following hierarchical levels:
Level 1: determined based on public price quotations (unadjusted) in active markets for identical assets and liabilities, including public debt securities, shares, listed derivatives.
Level 2: derived from data other than quoted prices included in Level 1 that are observable for the asset or liability, directly (as prices) or indirectly (derived from prices).
Level 3: are derived from valuation techniques that include data for assets or liabilities that are not based on observable market variables (unobservable data).
Financial Assets and Liabilities measured at fair value in profit or loss or through Other Comprehensive Income
Level 1: highly liquid bonds and securities with observable prices in an active market are classified at level 1. Most Brazilian Government Securities were classified at this level (mainly LTN, LFT, NTN-B and NTN-F), shares on the stock exchange and other securities traded on the active market.
Level 2: when price quotations cannot be observed, Management, using its own internal models, makes its best estimate of the price that would be set by the market. These models use data based on observable market parameters as an important reference. The best evidence of the fair value of a financial instrument at initial recognition is the transaction price, unless the fair value of the instrument can be obtained from other market transactions carried out with the same or similar instruments or can be measured using a valuation technique in which the variables used include only observable market data, mainly interest rates. These bonds and securities are classified at level 2 of the fair value hierarchy and are mainly composed of Public Securities (repo, LCI Cancellable and NTN) in a less liquid market than those classified at that level.
Level 3: when there is information that is not based on observable market data, Banco Santander uses models developed internally, aiming to adequately measure the fair value of these instruments. At level 3, instruments with low liquidity are classified mainly.
Derivatives
Level 1: derivatives traded on stock exchanges are classified at level 1 of the hierarchy.
Level 2: for Derivatives traded over the counter, for the evaluation of financial instruments (basically swaps and options), observable market data is normally used, such as exchange rates, interest rates, volatility, correlation between indices and market liquidity.
When pricing the financial instruments mentioned, the Black-Scholes model methodology is used (exchange rate options, interest rate index options, caps and floors) and the present value method (discounting future values using curves market).
Level 3: derivatives that are not traded on an exchange and that do not have observable information in an active market were classified as level 3, and are composed of exotic Derivatives.
The following table shows a summary of the fair values of financial assets and liabilities in the period ended March 31, 2026 and December 31, 2025, classified based on the various measurement methods adopted by the Bank to determine their fair value.

Fair value movements linked to credit risk
Changes in fair value attributable to changes in credit risk are determined based on changes in the prices of credit default swaps compared to similar obligations of the same obligor when such prices are observable, as these credit default swaps better reflect the market's assessment of the credit risks for a specific financial asset. When such prices are not observable, changes in fair value attributable to changes in credit risk are determined as the total amount of changes in fair value not attributable to changes in the basic interest rate or other observed market rates. In the absence of specific observable data, this approach provides a reasonable approximation of the changes attributable to credit risk, as it estimates the margin change above the reference value that the market may require for the financial asset.
Financial assets and liabilities not measured at fair value
The Bank's financial assets are measured at fair value in the consolidated balance sheet, except financial assets measured at amortized cost.
In the same sense, the Bank's financial liabilities - except financial liabilities for trading and those measured at fair value - are valued at
amortized cost in the consolidated balance sheet.

The fair value of the loans was determined by discounting the cash flows using the interest rates of the new contracts. That is, the future cash flow of the current credit portfolio is estimated based on contractual rates, and then spreads based on new loans are incorporated into the risk-free yield curve in order to calculate the value fairness of the credit portfolio. In terms of behavioral hypotheses, it is important to highlight that the prepayment rate is applied to the credit portfolio.
Deposits from the Central Bank of Brazil and deposits from credit institutions and customers – The fair value of deposits was calculated by discounting the difference between cash flows under contractual conditions and the rates currently practiced in the market for instruments with similar maturities. The fair value of variable rate term deposits was considered to be close to their book value.
Obligations for bonds and securities – The fair values of these items were estimated by calculating discounted cash flow using interest rates offered in the market for obligations with similar terms and maturities.
Debt Instruments Eligible for Capital – refer to the transaction fully agreed with a related party, in the context of the Capital Optimization Plan, whose book value is similar to the fair value.
Other financial liabilities – according to the explanatory note, substantially include amounts to be transferred arising from credit card operations, transactions pending settlement and dividends and interest on equity payable, whose book value is similar to its fair value.
The evaluation techniques used to estimate each level are defined in Note 1.c.3.1.i.

a)Derivative Financial Instruments
The main risk factors of the Derivative instruments assumed are related to exchange rates, interest rates and variable income. In managing this and other market risk factors, practices are used that include measuring and monitoring the use of limits previously defined in internal committees, the value at risk of portfolios, sensitivities to fluctuations in interest rates, exposure exchange rate, liquidity gaps, among other practices that allow the control and monitoring of risks, which can affect Banco Santander's positions in the various markets where it operates. Based on this management model, the Bank has managed, with the use of operations involving Derivative instruments, to optimize the risk-benefit relationship even in situations of great volatility.
The fair value of Derivatives financial instruments is determined through market price quotations. The fair value of swaps is determined using discounted cash flow modeling techniques, reflecting appropriate risk factors. The fair value of forward and futures contracts is also determined based on market price quotations for exchange-traded Derivatives or using methodologies similar to those described for swaps. The fair value of options is determined based on mathematical models, such as Black & Scholes, implied volatilities and the fair value of the corresponding asset. Current market prices are used to price volatilities. For Derivatives that do not have prices directly published by exchanges, the fair price is obtained through pricing models that use market information, inferred from published prices of more liquid assets. From these prices, interest curves and market volatilities are extracted, which serve as input data for the models.

IV) Accounting Hedge
The Bank, in the normal course of its operations, is exposed to market risks that generate accounting asymmetries or volatility in its accounting results. To eliminate these asymmetries or reduce volatility, the Bank uses Derivative financial instrument contracts (Swap and Futures) that are designated as fair value or cash flow Hedge Accounting structures.
IV.I) Fair Value Hedge
The Bank's fair value hedge strategy aims to protect the fair value of assets and liabilities, resulting from fluctuations in the reference interest rate (CDI, SELIC, SOFR); in currency fluctuations (Exchange Risk) and/or in price index fluctuations (IPCA, etc.). The Bank monitors each hedge structure, evaluating its effectiveness as determined by IAS 39.

IV.II) Cash Flow Hedge
The Bank's cash flow hedging strategies consist of hedging exposure to changes in cash flows, interest payments and exchange rate exposure, which are attributable to changes in interest rates relating to recognized assets and liabilities and changes of exchange rates of unrecognized assets and liabilities.
In cash flow hedges, the effective portion of the change in the value of the hedging instrument is temporarily recognized in equity under the caption “Other Comprehensive Income – cash flow hedges” until the expected transactions occur, when that portion is then recognized in the consolidated statements of income, except that, if the expected transactions result in the recognition of non-financial assets or liabilities, that portion will be included in the cost of the financial asset or liability.

V) Credit Derivatives Information
Banco Santander uses credit derivatives with the aim of managing counterparty risk and meeting the demands of its customers, carrying out purchase and sale protection operations through credit default swaps and total return swaps, primarily related to securities with Brazilian sovereign risk.
Total Return Swaps – TRS
These are credit derivatives where the return of the reference obligation is exchanged for a cash flow and in which, upon the occurrence of a credit event, the protection buyer usually has the right to receive from the protection seller the equivalent of the difference between the updated value and fair value (market value) of the reference obligation on the contract settlement date.
Credit Default Swaps – CDS
These are credit derivatives where, upon the occurrence of a credit event, the protection buyer has the right to receive from the protection seller the equivalent of the difference between the face value of the CDS contract and the fair value (market value) of the reference obligation on the contract settlement date. In return, the seller receives remuneration for selling the protection.

b)Operational Limits
Bacen requires financial institutions to maintain a Reference Equity (PR), Level I PR and Principal Capital compatible with the risks of their activities, higher than the minimum requirement of the Required Reference Equity, represented by the sum of the credit risk, market risk and operational risk installments.
As established in CMN Resolution No. 4,958/2021, the PR requirement is 11.50%, including 8.00% of Minimum Reference Equity, plus 2.50% of Capital Conservation Additive and 1.00% of Systemic Additive. The PR Tier I is 9.50% and the Minimum Principal Capital is 8.00%. In continuity with the adoption of the rules established by CMN Resolution No. 4,955/2021, the calculation of capital ratios is calculated on a consolidated basis based on information from the Prudential Conglomerate, whose definition is established by CMN Resolution No. 4,950/2021. The absolute value of the negative adjustment recorded in equity, resulting from the application, on January 1, 2025, of the criteria for establishing a provision for expected losses provided for in CMN Resolution No. 4,966, should impact capital in a phased manner, following the instructions and calendar of CMN Resolution No. 5,199.

(1) Credit risk exposures subject to calculation of the capital requirement using a standardized approach (RWACPAD) are based on the procedures established by BCB Resolution 229, of May 12, 2022.
(2) Exposures to market risk subject to calculation of the capital requirement using a standardized approach and an approach using internal models. The standardized approach includes portions for market risk exposures subject to changes in interest rates (RWAjur1), foreign currency coupons (RWAjur2), price indices (RWAjur3), and interest rate coupons (RWAjur4), the price of commodity goods (RWAcom), the price of shares classified in the trading portfolio (RWAacs), portions for exposure of gold, foreign currency and operations subject to exchange rate variation (RWAcam), and adjustment for derivatives arising from changes in the counterparty’s credit quality (RWAcva).
(3) Risk Weighted Assets or Risk-Weighted Assets.
Banco Santander publishes the Risk Management Report with information relating to risk management, a brief description of the Recovery Plan, capital management, PR and RWA. The report with greater detail on the premises, structure and methodologies can be found at the website www.santander.com.br/ri.
Financial institutions are obliged to maintain the investment of resources in Permanent Assets in accordance with the adjusted Reference Equity level. The resources invested in Permanent Assets, calculated on a consolidated basis, are limited to 50% of the value of the Reference Equity adjusted in accordance with CMN Resolution No. 4,957/2021. Banco Santander meets the established requirements.
c)Financial instruments - Sensitivity analysis
Risk management is focused on portfolios and risk factors, in accordance with Bacen regulations and good international practices.
Financial instruments are segregated into trading portfolios (Trading Book) and banking portfolio (Banking Book), as carried out in the management of market risk exposure, in accordance with the best market practices and the classification criteria for transactions and capital management established by the Central Bank of Brazil. The trading portfolio consists of all transactions with financial instruments and commodities, including Derivatives, held with the intention of trading. The banking portfolio consists of structural operations arising from Banco Santander's various business lines and their possible hedges. Therefore, according to the nature of Banco Santander's activities, the sensitivity analysis was divided between the trading and banking portfolios.
Banco Santander carries out sensitivity analysis of financial instruments in accordance with CVM Instruction No. 2/2020, considering market information and scenarios that would negatively affect the Bank's positions.
The summary tables presented below summarize sensitivity values generated by Banco Santander's corporate systems, referring to the trading portfolio and banking portfolio, for each of the portfolio scenarios on March 31, 2026.

d) Funds managed and administered not recorded on the balance sheet
The Santander Conglomerate has funds under management, in which it does not have a significant stake, does not act as "main" and does not hold shares in these Funds. Based on the contractual relationship that governs the management of such funds, the third parties who hold the shareholding are those who are exposed, or have rights, to variable returns and have the ability to affect these returns through decision-making power. Furthermore, the Bank, as manager of the funds, acts in the analysis of remuneration regimes, which are proportional to the service provided and, therefore, acts as "main".
The funds managed by the Santander Conglomerate not recorded on the balance sheet are as follows:
| 03/31/2026 | 12/31/2025 | |||||||||||||
| Managed funds | 235,237,871 | 227,012,763 | ||||||||||||

e) Securities held by third parties in custody
As of March 31, 2026, and December 31, 2025, the Bank held in custody debt securities and securities of third parties totaling R$133.685.104 and R$146.156.911, respectively.
19.Subsequent Events
a)Distribution of Interest on Equity
The Board of Directors of Banco Santander, at a meeting held on April 10, 2026, approved the proposal of the Company's Executive Board, subject to ratification by the Ordinary General Meeting, for the distribution of Interest on Equity in the amount of R$ 2,000,000,000.00 (two billion reais), based on the balance of the Company's Dividend Equalization Reserve. Shareholders registered in the Bank's records at the end of the day on April 20, 2026 (inclusive) were entitled to the Interest on Equity. Therefore, from April 22, 2026 (inclusive), the Bank's shares were traded "Ex-Interest on Equity". The Interest on Equity will be paid starting May 7, 2026. The Interest on Equity was fully allocated to the minimum mandatory dividends distributed by the Bank for the fiscal year 2026, without any remuneration for monetary adjustment.
