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 June 30, 2026, the Condensed Consolidated Financial Statements have been prepared in accordance with IAS 34 Interim Financial Reporting.

The Condensed Consolidated Financial Statements prepared in accordance with the international accounting standard issued by the International Accounting Standards Board (IASB) relating to the semester that ended in June 30, 2026, will be published on July 29, 2026, at www.santander.com.br/ri.


Economic Situation

The economic performance was highlighted by the following themes:


v Surprising Resilience of the U.S. Economy
The U.S. economy once again delivered a positive surprise, demonstrating resilience even amid higher oil prices and rising energy costs. The labor market remains the main highlight, with average job creation exceeding 100,000 positions in recent months, above the 75,000 recorded in Q1 2026 and well above the average of 25,000 observed in 2025. The combination of solid economic activity and persistent inflationary pressures has led the Federal Reserve to adopt a more cautious stance. Committee projections remain divided between further interest rate hikes and some degree of monetary easing, reflecting the high level of uncertainty surrounding the outlook, now further reinforced by Kevin Warsh’s appointment as Chair of the institution..

v Oil Remains at the Center of Global Macroeconomic Dynamics

The main driver of the second quarter of 2026 continued to be the strong volatility in oil prices. After reaching approximately USD 120 per barrel between late April and early May, Brent crude declined significantly, ending June at around USD 73 per barrel, essentially returning to the levels observed before the escalation of the conflict in the Middle East. This movement was driven primarily by developments in geopolitical tensions and the flow of oil through the Strait of Hormuz. As prices normalized, concerns about additional short-term inflationary impacts stemming from energy costs eased. Nevertheless, the outlook remains surrounded by uncertainty. Although the conflict has lost momentum compared to previous months and there has been some progress in negotiations toward a peace agreement, substantial differences between the parties remain. As a result, the risk of further disruptions to oil supply continues to be present, keeping price volatility elevated and maintaining uncertainty regarding its potential effects on inflation and global economic growth..

v Central Banks Respond Cautiously.
In terms of monetary policy, the quarter was marked by increased caution among major central banks. The Federal Reserve kept its policy rate unchanged at its January and March meetings, maintaining a data-dependent stance in an environment where inflation remained above target. Throughout the quarter, the Fed began signaling a less favorable inflation outlook, with higher inflation projections and less conviction regarding a potential resumption of the rate-cutting cycle, particularly following the energy shock, which added further upside risks to the scenario. The European Central Bank also left interest rates unchanged and explicitly acknowledged that the escalation of the conflict in the Middle East is expected to put upward pressure on inflation in the short term through energy prices. Overall, the global environment remained in a wait-and-see mode, as the interest rate outlook became subject to greater uncertainty in the face of an adverse supply shock.


v Activity Remains Resilient, but Signs of Moderation Are Becoming More Visible.

The Brazilian economy continued to perform better than expected throughout Q2 2026, supported by household consumption, a still-dynamic labor market, and the lingering impact of income-support measures implemented at the beginning of the year. At the same time, more consistent evidence of a slowdown began to emerge in segments that are more sensitive to monetary policy, particularly in credit markets and in some leading economic activity indicators. The quarter’s overall performance reinforced the assessment that the economy is moving toward a gradual deceleration. In this context, our GDP growth forecast remains at 1.8% for 2026, and we now expect growth of 1.3% in 2027, still consistent with a healthy moderation of domestic demand over the relevant forecast horizon.

v Inflation Shows Improvement Again, but Expectations Remain Unanchored.

Q2 2026 began under the lingering effects of the oil price shock, which continued to put pressure on production costs. This impact, however, was partially offset by the appreciation of the Brazilian real, which helped limit the pass-through to domestic prices. Throughout the quarter, the gradual normalization of international oil prices reduced pressures on fuel, freight, and industrial goods, allowing for an improvement in current inflation dynamics. Despite this relief, inflation remained above target and expectations continued to be unanchored, reflecting the resilience of economic activity and uncertainties surrounding the fiscal environment. In this context, we maintain our assessment that convergence toward the target will remain gradual and will depend on restrictive monetary conditions being maintained for an extended period. Our IPCA inflation forecast stands at 5.0% for 2026 and 4.0% for 2027

v Copom Reinforces a Cautious Stance.

Throughout the quarter, the Central Bank maintained the monetary easing process but reinforced the message that room for additional rate cuts has become more limited. The combination of persistently elevated inflation expectations, still-expansionary fiscal policy, and tighter global financial conditions led Copom to adopt a more conservative communication regarding the Selic rate path. The prevailing assessment became that the cost of bringing inflation back to target has increased, requiring interest rates to remain elevated for longer. In our baseline scenario, we project the Selic rate to end 2026 at 13.75% and 2027 at 12.75%, within a more gradual easing cycle conditioned on the evolution of inflation and expectations, as well as the fiscal stance and the degree of spare capacity in the economy going forward.








The first half of 2026 was marked by the continued execution of our strategy, maintaining customer centricity as a fundamental element of value creation. We continued to strengthen our relationships with customers, expand revenue diversification, and make progress in building an increasingly solid, efficient and resilient operation. In terms of results, we closed the first half with recurring managerial net profit of R$ 6.8 billion in the period, down 9.6% compared to the same period of 2025, reflecting a macroeconomic environment characterized by higher household indebtedness and the persistence of elevated interest rates.
Total revenues reached R$ 41.9 billion in the period, up 0.6% compared to the first half of 2025. Results performance was mainly supported by the performance of customer-related businesses and the growth in service revenues, reinforcing the consistency of our business model and the quality of our business.
Client NII increased 2.2% in the first half, totaling R$ 32.6 billion, reflecting the 5.8% growth in our loan portfolio, especially consumer finance operations, which grew 15.3%, as well as operations with SMEs, which increased 11.4%. Market NII, in turn, recorded a negative result, mainly due to the negative sensitivity to rising interest rates and lower treasury results.
Fees increased 4.1% in the first half, reaching R$ 10.8 billion, with highlights including cards, up 8.1% YoY, insurance, up 9.3% YoY, and capital markets, up 17.4% YoY. The result demonstrates the growing contribution of service businesses to recurring revenue generation and reinforces our diversification strategy.
In terms of asset quality, the result from loan losses totaled R$ 14.0 billion in the first half of 2026, up 5.6% compared to the same period of the previous year. This performance reflects the persistence of a challenging macroeconomic environment, marked by elevated interest rates, requiring higher levels of provisioning in the period.
In expenses, we continued to make progress in productivity and operational efficiency, totaling R$ 13.2 billion in the first half, an increase of 1.7% compared to the same period in 2025. This growth remained below inflation in the period, demonstrating disciplined cost management and a continued focus on the efficient allocation of resources.
We remain committed to delivering sustainable long-term results, supported by a more diversified operation, disciplined capital and risk management, and a continuous focus on offering the best solutions and experiences to our customers.

Internal Audit

Internal Audit reports directly to the Board of Directors and is overseen by the Audit Committee, acting permanently, independently, and objectively in relation to the other functions and units of the Organization. Its mission is to provide the Board of Directors and Senior Management with independent assurance on the quality and effectiveness of governance, risk management, and internal control processes, contributing to the protection of the Organization's value, solvency, sustainability, and reputation.
The Internal Audit function has a quality certification issued by the Institute of Internal Auditors (IIA), in recognition of its adherence to international standards and best practices of the profession.
To fulfill its duties and ensure adequate coverage of the risks inherent in Banco Santander's activities, Internal Audit uses methodologies and tools developed internally. Of particular note is the risk matrix, used in the planning process to prioritize the auditable universe based on criteria such as inherent risk, results of previous assessments, level of implementation of audit recommendations, and relevance of processes to the Organization. Work programs are reviewed periodically to reflect the evolving risk environment, regulatory changes, and transformations in the business environment.
In line with its oversight role, the Audit Committee recommended approval of the 2026 Annual Audit Plan and Annual Internal Audit Report, which were subsequently approved by the Board of Directors.

People

Banco Santander continues to strengthen its organizational culture, which seeks to contribute to the prosperity of people and businesses. Autonomy, proactivity, and innovation gain space, accelerate digital transformation, and enhance the personalized offering for the most diverse segments of society.

There are 47,327 employees, considering the entire Group, committed to the ambition of generating unique and personalized customer experiences, so that we are the main bank for each of our clients.



To this end, the bank continuously invests in creating an environment where leadership is a benchmark in the organization's values, an inclusive culture ensures that each professional feels recognized and engaged in building their career, health and well-being are central, and continuous learning serves the constant improvement of the customer journey and the evolution of each employee. Growth opportunities are democratized and within everyone's reach.

Sustainability

Sustainability has been integrated into Santander's business strategy for over 20 years and guides our actions in risk management, the development of financial solutions, and the generation of positive impact for clients, communities, and society.

During the semester, we maintained our focus on the areas where we have the greatest capacity to contribute: assessment and mitigation of social, environmental, and climate risks in credit granting; support for clients in the transition to a low-carbon economy; and promotion of initiatives in education, employability, entrepreneurship, and financial inclusion.

Our actions are concentrated on the most relevant issues for the business, considering impacts, risks, and opportunities, and are accompanied by global goals in priority areas such as decarbonization, financial inclusion, and inclusive culture. This agenda is supported by robust policies, controls, and governance structures, with the support of senior leadership.

At the end of 2Q26, we highlight the following results:


Sustainable business

v We facilitated R$ 24.7 billion in sustainable business, including green bond issuances, clean energy financing, and dedicated products such as CDC Solar and CDC Electric and Hybrid Vehicles, reaching R$ 57.8 billion in the sustainable credit portfolio¹, with 43% growth (YoY).

We also carried out Acelera Tech AWS – Training for SMEs and Startups, a program developed in partnership with Amazon Web Services (AWS), which provided free training in technology, cloud computing, and digital transformation, supporting companies at different stages of maturity in adopting innovative business solutions. In this edition, 329 scholarships were awarded to SMEs and 135 scholarships to startups, totaling 464 training scholarships.







Independent Audit

Banco Santander’s policy, including its controlled companies, regarding the engagement of services unrelated to the audit of the Financial Statements by its independent auditors, PricewaterhouseCoopers, is based on Brazilian and international auditing standards that preserve auditor independence. This framework establishes that: (i) the auditor must not audit its own work; (ii) the auditor must not perform management functions for its client; (iii) the auditor must not advocate for its client’s interests; and (iv) any services must be approved by the Bank’s Audit Committee.

In compliance with Brazilian Securities and Exchange Commission (CVM) Instruction No. 162/2022, Banco Santander informs that, during the six-month period ended June 30, 2026, PricewaterhouseCoopers did not provide any services unrelated to the independent audit of the Financial Statements of Banco Santander and its relevant controlled companies that could create a conflict of interest, impair independence, or affect the objectivity of its independent auditors. PricewaterhouseCoopers maintains procedures, policies, and controls designed to ensure its independence, including an assessment of all services provided, encompassing any engagement other than the independent audit of Banco Santander’s Financial Statements and those of its controlled companies. Such assessment is based on applicable regulations and accepted principles that safeguard auditor independence.

Acknowledgments

We thank our customers, shareholders, and employees for the trust and support that have driven us to this point, and which have enabled the continuation of our history of evolution and transformation, on the path to building the Best Consumer Company in Brazil.

Report on review of consolidated condensed
interim financial statements


To the Board of Directors and Stockholders
Banco Santander (Brasil) S.A.




Introduction

We have reviewed the accompanying consolidated condensed balance sheet of the Banco Santander (Brasil) S.A. (the "Bank") and its subsidiaries, at June 30, 2026 and the related consolidated condensed statements of income and comprehensive income for the quarter and six-month period then ended, and the consolidated condensed statements of changes in equity and cash flows for the six-month period then ended, and explanatory notes.

Management is responsible for the preparation and presentation of the consolidated condensed interim financial statements in accordance with the International Accounting Standard (IAS) 34 - Interim Financial Reporting, of the International Accounting Standards Board (IASB). Our responsibility is to express a conclusion on these condensed interim financial statements based on our review.

Scope of review

We conducted our review in accordance with Brazilian and International Standards on Reviews of Interim Financial Information (NBC TR 2410 - Review of Interim Financial Information Performed by the Independent Auditor of the Entity, and ISRE 2410 - Review of Interim Financial Information Performed by the Independent Auditor of the Entity, respectively). A review of interim information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with Brazilian and International Standards on Auditing and consequently did not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion

Based on our review, nothing has come to our attention that causes us to believe that the accompanying consolidated condensed financial statements referred to above are not prepared, in all material respects, in accordance with the International Accounting Standard (IAS) 34 - Interim Financial Reporting, of the International Accounting Standards Board (IASB).



Other matters - Consolidated Condensed statement of value added

The condensed financial statements referred to above include the consolidated condensed statement of value added for the six-month period ended June 30, 2026. This statement is the responsibility of the Bank's management and presented as supplementary information. This statement was subjected to review procedures performed together with the review of the condensed financial statements for the purpose of concluding whether it is reconciled with the condensed financial statements and accounting records, as applicable, and if its form and content are in accordance with the criteria defined in the accounting standard
CPC 09 - "Statement of Value Added". Based on our review, nothing has come to our attention that causes us to believe that this consolidated condensed statements of value added has not been prepared, in all material respects, in accordance with the criteria established in this accounting standard, and that it is consistent with the consolidated condensed financial statements taken as a whole.

1.Operating context, presentation of consolidated condensed financial statements and other information

a)Operational Context

The 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 June 30, 2026, at the meeting held on July 28, 2026.

The aforementioned Condensed Consolidated Financial Statements were recommended for approval by Santander Bank’s Audit Committee.

b)Presentation of Consolidated Condensed Interim Financial Statements (prepared in accordance with IAS 34)
The Condensed Consolidated Financial Statements have been prepared in accordance with IAS 34 Interim Financial Reporting. All relevant information specifically relating to, and only to, Banco Santander's Financial Statements is disclosed and corresponds to the information used by Banco Santander in its management. There is no change in applicable practices and policies between the condensed consolidated financial statements and the statements published on the Investor Relations website, with a base date of December 31, 2025.
c.1)Adoption of new standards and interpretations
•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 assessing the impacts of this change.

•IFRS 19 – Subsidiaries without Public Liability: Disclosures: which allows a subsidiary to provide reduced disclosures when applying IFRS Accounting Standards to its financial statements. IFRS 19 is optional for eligible subsidiaries and sets out 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 prior application permitted. Santander is evaluating the impacts of this change.

•IFRS 20 – Regulatory Assets and Regulatory Liabilities: establishes requirements for the recognition, measurement, presentation, and disclosure of regulatory assets and liabilities arising from certain types of tariff regulation. The standard aims to provide more relevant and comparable information on the effects of tariff regulation on the financial statements of entities subject to this regulatory environment. Management does not expect material impacts from the adoption of this standard.

•Amendments to IAS 28 – Investments in Associates and Joint Ventures: clarifies the application of the fair value measurement option for certain investments in associates and joint ventures by eligible entities. The amendments aim to promote greater consistency in the application of the standard and reduce discrepancies observed in practice. Management does not expect material impacts from the adoption of this standard.
c.2)Estimates used
The consolidated results and the determination 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 values of assets and liabilities for future periods. All estimates and assumptions required under IFRS are management's best estimate under applicable standards.

In the consolidated financial statements, estimates are made by the Bank's management and the consolidated entities in order to quantify certain assets, liabilities, revenues, and expenses, and for explanatory note disclosures.
c.2.1) 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 notes to the financial statements, are described below:

i. Fair Value Assessment of Certain Financial Instruments

Financial instruments are initially recognized at fair value, and those 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 that 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 a 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 June 30, 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.3) 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 (note 3.a.).

(1) On June 30, 2026, the balance recorded in “Loans and advances to customers” referring to operations of the assigned credit portfolio is R$15,260 (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 semester ended June 30, 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 June 30, 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”, with movements occurring during the interim period recognized in the respective 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

Changes in provisions for recoverable value losses of assets included in “Financial Assets Measured at Amortized Cost - Loans, Other Amounts with Credit Institutions, Advances to Customers and Debt Instrument” (1) in the semesters ended June 30, 2026 and 2025 were the following:

01/01 to 01/01 to
06/30/2026 06/30/2025
Balance at beginning of the period  
40,694,182 35,668,907
Constitution (Reversal) for losses on financial assets 12,347,131 16,660,974
Write-off of impaired balances against recorded impairment allowance (11,135,145) (13,956,309)
Exchange Variation (18,475) (25,389)
Balance at end of the period (Note 3.a)
41,887,693 38,348,183
Provision for contingent liabilities 841,534 454,770
Total balance of allowance for impairment losses, including provisions for contingent liabilities 42,729,227 38,802,953
Loans written-off recovery 376,207 669,077
Discount granted (2,487,983) (1,396,261)

(1) Includes Provision for Losses on Financial Guarantee Contracts Provided.

Considering the amounts recognized in “Constitution (Reversal) for losses on financial assets”, “Recoveries of loans written off as losses” and “Discount Granted” total R$ 14,458,907 and R$ 17,388,158 in the semesters ended June 30, 2026 and 2025 , respectively.

Considering the plan to update the impairment provision calculation models, to be implemented during the second half of 2025, the recognized balance of supplementary provision (post model adjustment) is 1,389 million as of June 30, 2026, to meet the update of macroeconomic parameters and other relevant parameters of the Bank's impairment provision calculation models, in accordance with IFRS 9, which resulted in higher provisions, reflecting a more complex economic environment expected.

c)Non-recoverable assets

A financial asset is considered unrecoverable when there is objective evidence of the occurrence of events that: (i) cause an adverse impact on the estimated future cash flows at the date of the transaction, in the case of debt instruments (loans and debt securities); (ii) mean that its carrying amount cannot be fully recovered, in the case of equity instruments; (iii) arise from the breach of clauses or terms of loans, and (iv) at the time of bankruptcy proceedings.

Details of changes in the balance of financial assets classified as “Loans, advances to customers and Debt Instruments” considered as non-recoverable due to credit risk in the semesters ended June 30, 2026 and 2025 are as follows:






01/01 to 01/01 to
06/30/2026 06/30/2025
Balance at beginning of the period  
48,899,708  42,242,354 
Net additions  17,505,609  12,521,015 
Write-off of impaired balances against recorded impairment allowance (11,699,626) (11,023,481)
Balance at end of the period  54,705,691  43,739,888 


d)Provisions for Losses of Financial Guarantee Contracts Provided

IFRS 9 requires that the provision for expected credit losses be recorded for financial guarantee contracts provided, that have not yet been honored. It should be measured and accounted for at the provision expense that reflects the credit risk in the event of honored guarantees and the endorsed customer does not comply with its contractual obligations. Below is the movement of these provisions for the semesters ended June 30, 2026 and 2025.

01/01 to 01/01 to
06/30/2026 06/30/2025
Balances at the beginning of the period  
787,837  440,113 
Constitution (Reversal) of provision for losses on financial guarantee contracts provided 53,697  14,657 
Balances at the end of period

4.Non-current assets held for sale

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 June 30, 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 integral parties to judicial and administrative proceedings of a fiscal, social security, labor, and civil nature, arising from the normal course of their activities.

The provisions were established based on the nature, complexity, and history of the lawsuits and on the assessment of the loss of the companies' shares based on the opinions of internal and external legal advisors. Banco Santander's policy is to fully provision the value at risk of lawsuits whose assessment is of probable loss.

Management believes that the provisions established are sufficient to cover any potential losses arising from judicial 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.

National Social Security Institute (INSS) - R$ 172 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$ 377 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.

PIS and COFINS - Income on Mandatory Reserve Deposits - R$ 1,322 million (12/31/2025 - R$ 995) at the Bank and R$ 1,322 million (12/31/2025 - R$ 995 million) on a Consolidated basis, and is fully covered by a mass claim. The Company filed a lawsuit seeking to exempt the remuneration earned on compulsory deposits held with the Central Bank of Brazil (BACEN) from PIS and COFINS taxation. In 2024, a favorable court ruling was issued; however, the Brazilian National Treasury (Fazenda Nacional) subsequently appealed the decision.

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.

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$ 37,815 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 June 30, 2026, the amount involved is R$ 2,437 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 June 30, 2026, the value was approximately R$ 12,260 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 June 30, 2026, the value was approximately R$ 3,767 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 June 30, 2026, the value was approximately R$ 6,502 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 June 30, 2026, the value was approximately R$ 1,190 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 June 30, 2026, the value was approximately R$ 2,835 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 June 30, 2026, the amount was approximately R$ 860 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 June 30, 2026, the amount was approximately R$ 740 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 June 30, 2026, the value was approximately R$ 495 million.




Actions of a labor and civil nature classified as possible losses totaled R$ 1,518 million and R$ 2,108 million, respectively, on a Consolidated basis.

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
06/30/2026 06/30/2025
Program Type of Liquidation 
Local Santander Shares (Brazil) 12,665  3,477 
Global Global Stocks and Options 1,875  3,169 
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
06/30/2026 06/30/2025
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) 129,455  134,521 
Unidentified Collective Other employees with variable remuneration above a minimum expected value 50% in cash indexed to 100% of the CDI and 50% instruments 97,445  102,797

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 quoted market prices are not observable, Management uses its own internal models to make its best estimate of the price that would be established 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 involving the same or similar instruments, or can be measured using a valuation technique whose inputs consist solely of observable market data, particularly interest rates. At Level 2, they are classified primarily by Central Bank of Brazil reserves (repurchase agreements).

Level 3: When information is not based on observable market data, Banco Santander uses internally developed models to appropriately measure the fair value of these instruments. At Level 3, they are classified primarily by government bonds (NTN-C).

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: The derivatives that are not traded on an exchange and for which observable information is not available in an active market are classified as Level 3 and some structured derivatives are composed of them.

The following table shows a summary of the fair values of financial assets and liabilities in the period ended June 30, 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 methods and assumptions used to estimate fair value are defined below:
Loans and other amounts with credit institutions and customers – The fair value is estimated by groups of similar credit operations. 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.






18.Other disclosures

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 hedging strategy aims to protect the fair value of assets and liabilities against fluctuations in benchmark interest rates (CDI, SELIC, SOFR) and fixed rates, currency fluctuations (foreign exchange risk), and/or price index fluctuations (IPCA). The Bank monitors each hedging structure by assessing its effectiveness in accordance with IFRS 9.

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.

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.

(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 June 30, 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:
06/30/2026 12/31/2025
Managed funds 267,598,148  227,012,763 
Total 267,598,148  227,012,763 


e) Securities held by third parties in custody

As of June 30, 2026, and December 31, 2025, the Bank held in custody debt securities and securities of third parties totaling R$ 136.452.702 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 July 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 July 21, 2026 (inclusive) were entitled to the Interest on Equity. Therefore, from July 22, 2026 (inclusive), the Bank's shares were traded "Ex-Interest on Equity". The Interest on Equity will be paid starting August 6, 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.

b) Merger of Santander Leasing by Banco Santander (Brasil) S.A.

On July 1, 2026, Banco Santander (Brasil) S.A. ("Santander Brasil") received approval from the Central Bank of Brazil regarding the merger of Santander Leasing S.A. – Arrendamento Mercantil ("Santander Leasing"), as approved by the General Meetings of both companies held on November 28, 2025.
With the approval by the Central Bank of Brazil, all the necessary conditions for the completion of the transaction were met, and it became effective from that date.
The merger did not result in an increase in the share capital of Santander Brasil, since all the shares issued by Santander Leasing were held by it. Therefore, the investment was already fully recognized in the financial statements of Santander Brasil using the equity method, and there was no equity impact resulting from the merger.

Audit Committee Report

The Audit Committee of Banco Santander (Brasil) S.A. (“Santander”), the leading institution of Santander’s Economic and Financial Conglomerate (the “Conglomerate”), operates as a single committee for all institutions and companies comprising the Conglomerate, including those entities supervised by the Brazilian Superintendence of Private Insurance (Susep).

Pursuant to its Internal Regulations, available on Santander’s Investor Relations website (www.ri.santander.com.br), the Audit Committee, among its responsibilities, assists the Board of Directors in assessing the adequacy of the financial statements, verifying compliance with legal and regulatory requirements, evaluating the effectiveness and independence of the work performed by internal and external auditors, and monitoring the effectiveness of internal control systems and operational risk management. Additionally, whenever deemed necessary and applicable, the Audit Committee recommends improvements and corrective actions to policies, practices, and procedures identified within the scope of its responsibilities.

The Audit Committee is composed of four independent members, re-elected pursuant to the resolution adopted at the Board of Directors’ meeting held on May 7, 2026. The Committee carries out its activities through meetings with executives, auditors (internal and external), and specialists (local and from the Conglomerate, when necessary), and conducts analyses based on documents and information submitted to it, taking any additional actions necessary to fulfill its duty of care. The Audit Committee’s assessments are based primarily on information received from Executive Management, the results of internal and external audits, and the areas responsible for monitoring internal controls, Compliance, and operational risks.

Reports on the Audit Committee’s activities and the content of its meetings are regularly presented to the Board of Directors through reports made by the Committee Chair during Board meetings.

Within the scope of its responsibilities, during the period from January 1 to July 31, 2026, the Audit Committee carried out the following activities:

Financial Statements

he Audit Committee analyzed the Individual and Consolidated Financial Statements of Banco Santander (Brasil) S.A. and its Subsidiaries that comprise the Economic and Financial Conglomerate for the first half of 2026, confirming their adequacy and recommending their approval by the Board of Directors.

In carrying out this analysis and recommendation, the Audit Committee met with the independent auditors, the Financial Vice Presidency, and the professionals responsible for Accounting and the preparation of the financial statements prior to recommending their approval to the Board of Directors and their disclosure to the market.

Internals Controls and Operational Risks Management

The Audit Committee regularly participated in Risk and Compliance Committee meetings, received information from, and held meetings with, the Executive Vice Presidency of Risk, the Compliance Department, Internal Controls, and the main bodies responsible for managing, implementing, and promoting the Conglomerate’s culture and infrastructure of internal controls, risk management, and Conduct controls. It also reviewed matters being monitored through the Open Channel (the whistleblowing channel), as well as cases handled by the Information Security and Fraud Prevention areas. These reviews were carried out in accordance with applicable regulations.

Internal Audit

The Audit Committee formally met with the officer responsible for Internal Audit and its representatives on several occasions during the first half of 2026. In addition to monitoring reports regarding the progress of the 2026 Internal Audit Plan and the work performed, the Committee reviewed issued reports, their conclusions, and recommendations, highlighting (i) the fulfillment of recommendations for improvements in areas which controls were considered "To be improved"; (ii) the results of the improvements applied to monitor and comply with the recommendations and their action plans for continuous progress; and (iii) meeting the demands of regulatory bodies. In several other occasions, Internal Audit professionals attended the meetings of the Audit Committee, providing expert information.

Independent Audit

Regarding the Independent Audit work performed by PricewaterhouseCoopers Auditores Independentes (“PwC”), the Audit Committee formally met with the firm on several occasions during the first quarter and second quarter of 2026. Key topics discussed included the financial statements for the first half of 2026, accounting practices, key audit matters (KAMs), and any deficiencies and recommendations for improvement contained in the internal controls report. In addition, the Committee met with the Independent Auditor in executive sessions to discuss matters of interest, such as digital assets and cryptocurrencies.




The Audit Committee evaluated proposals submitted by PwC for the provision of other services from the perspective of the absence of conflicts of interest or risks to auditor independence and approved them in accordance with the Audit Services Approval Policy.
The Committee also met with the independent auditors of Banco RCI Brasil S.A., a member of the Conglomerate, namely KPMG Auditores Independentes (“KPMG”), responsible for auditing the 2025 Financial Statements, and Forvis Mazars, responsible for auditing the Financial Statements for the audit cycle that began in 2026.

Ombudsman

In accordance with applicable regulations, the Audit Committee monitored the work performed by the Ombudsman function, which was presented to, discussed, and evaluated by the Committee. In addition to receiving reports on activities carried out in 2026, the Committee reviewed the Ombudsman’s semiannual report for the semester ended June 30, 2026, covering Banco Santander (Brasil) and its affiliated companies, as well as Conglomerate companies that maintain their own Ombudsman structures.

Regulatory Bodies

The Audit Committee monitors official communications received from regulatory authorities, follows ongoing inspections, and reviews the findings and observations of regulatory and self-regulatory bodies, related action plans, and the measures adopted by management to address such findings. The Committee also monitors new regulations and meets with regulators whenever requested. With respect to the Central Bank of Brazil, it maintains regular meetings with supervisors of the Department of Banking Supervision (Desup).

Related Parties

During the period covered by this report, the Audit Committee monitored and evaluated related-party transactions, deepening its understanding through internal meetings with counterparties and by obtaining independent opinions whenever necessary. In cases involving related-party transactions with global counterparties, the Committee also interacted with their respective global representatives.

Others Activities

In addition to the activities described above, and as part of its responsibilities, the Audit Committee met with executive officers and several areas of the Conglomerate to further deepen its analyses. Particular attention was given to monitoring the following topics: (i) regulatory capital; (ii) monitoring of cybersecurity; (iii) Sustainability themes, amongst with Sustainability Committee; (iv) conduct, PLD/CFT, KYC, policies and action plans for continuous improvements; (v) activities of the customer relations department, its action plans and results; (vi) tax, labor and civil litigation; (vii) review and approval of the Tax Credit Realization Technical Study; and (viii) provisions and topics related to PCLD.

During the period, members of the Audit Committee also participated in training sessions, lectures and programs on topics related to its activities, and on regulations of interest and impact to the Conglomerate.

Conclusion

Based on the work and assessments carried out, and considering the context and scope in which it carries out its activities, the Audit Committee concluded that the work carried out is appropriate and provides transparency and quality to the Financial Statements of Banco Santander (Brasil) S.A. and Controlled Companies consolidated in Economic and Financial Conglomerate for the semester ended in June 30, 2025, recommending their approvals by the Board of Directors of Santander.
