Report on review of consolidated condensed

To the Board of Directors and Stockholders

Banco Santander (Brasil) S.A. and its subsidiaries

Introduction

We have reviewed the consolidated condensed balance sheet of Banco Santander (Brasil) S.A. ("Bank") and its subsidiaries as at September 30, 2024 and the related consolidated condensed statements of income and comprehensive income for the three and nine-months period then ended, and changes in stockholders' equity and cash flows for the nine-months period then ended, and explanatory notes.

Management is responsible for the preparation and presentation of these consolidated condensed interim financial statements in accordance with the International Accounting Standard (IAS) 34 - "Interim Financial Reporting" issued by the International Accounting Standards Board (IASB). Our responsibility is to express a conclusion on these consolidated 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 interim financial statements referred to above are not prepared, in all material respects, in accordance with the International Accounting Standard IAS 34 - "Interim Financial Reporting" issued by the International Accounting Standards Board (IASB).

Banco Santander (Brasil) S.A.

Other matters

Condensed statement of value added

The consolidated condensed interim financial statements referred to above include the consolidated condensed statement of value added for the nine-months period ended September 30, 2024, prepared under the responsibility of the Bank's management and presented as supplementary information in appendix I to the condensed consolidated interim financial statements for IAS 34 purposes. This statement has been subjected to review procedures performed together with the review of the consolidated condensed interim financial statements, for the purpose of concluding whether it is reconciled with the consolidated condensed interim 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 statement of value added has not been properly prepared, in all material respects, in accordance with the criteria established in this accounting standard, and consistent with the consolidated condensed interim financial statements taken as a whole.

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 authorized the issuance of the condensed consolidated interim Financial Statements for the period ended September 30, 2024, at the meeting held on 28 October, 2024.

The aforementioned Financial Statements were subject to a recommendation for approval issued by Banco Santander's Audit Committee and an unqualified report from the Independent Auditors.

b)Presentation of condensed consolidated 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 IFRS® Interpretations Committee (current name of the International Financial Reporting Interpretations Committee – IFRIC®). All relevant information specifically related to Banco Santander's Financial Statements, and only in relation to these, is being disclosed, and corresponds to the information used by Banco Santander in its administration. There is no change in applicable practices and policies between the Condensed Consolidated Interim Financial Statements and the Complete Statements.

c)Other Information

c.1)Adoption of new standards and interpretations

· Amendments to IAS 1 – Presentation of Financial Statements: The amendments aim to specify the requirements for classifying liabilities as current or non-current. The amendments clarify what is meant by the right to postpone settlement; whereas the right to postpone must exist at the end of the financial reporting period; that the rating is not affected by the likelihood that the entity will exercise its right to postpone; and that only a derivative embedded in a convertible liability is itself an equity instrument, the terms of a liability will not affect its classification. The amendments to IAS 1 were effective from January 1, 2024 and did not have any significant impacts.

· Amendment to IAS 1 and IFRS Practice Statement 2 – Disclosure of accounting policies: Change of the term “significant accounting policies” to “material accounting policies”. The change also defines what is “material accounting policy information”, explains how to identify it and clarifies that immaterial accounting policy information does not need to be disclosed, but if are, which should not obscure relevant accounting information. The "IFRS Practice Statement 2 Making Materiality Judgments", also amended, provides guidance on how to apply the concept of materiality to accounting policy disclosures.

· Amendment to IAS 7 – Statement of Cash Flows and IFRS 7 – Financial Instruments: Disclosure: Requires entities to provide additional disclosures about their supplier financing agreements. The IASB issued these new requirements to provide users of financial statements with information that allows them to evaluate how supplier financing arrangements affect an entity's obligations and cash flows, and understand the effect of supplier financing arrangements on an entity's exposure. entity to liquidity risk and how the entity could be affected if the arrangements were no longer available to it. The changes to IAS 7 and IFRS 7 were effective from January 1, 2024 and did not have any relevant impacts.

· Amendment to IFRS 16 – Leases: Clarifies the requirements that a seller-lessee uses in measuring the lease liability arising from a sale and leaseback transaction in order to ensure that the seller-lessee does not recognize any amount of gain or loss that relates to the right to use that he keeps. The amendments to IFRS 16 were effective from January 1, 2024 and did not have any relevant impacts.

c.2)New standards and interpretations in force in future years

· 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, investment and financing) in the income statement structure. It also required companies to disclose explanations on performance measures defined by management related to the income statement.

* Values expresses in thousands, unless otherwise indicated.

These changes are effective for years beginning January 1, 2027. Santander is evaluating the impact of this change.

· Amendment to IAS 21 – Effects of Changes in Exchange Rates and Conversion 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 that limit the volume of foreign currency transactions. 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 exchange, as well as requiring the disclosure of information that allows users of the Financial Statements to understand the impacts of a currency without convertibility. These changes are effective from January 1, 2025. Santander is evaluating the impacts of this change.

· IFRS 19 – Non-Publicly Responsible Subsidiaries:Disclosures: which 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 1 January 2027, with earlier application permitted. Santander is assessing the impacts of this change.

· Amendments to IFRS 9 and IFRS 7 - Amendments to the Classification and Measurement of Financial Instruments: To address issues identified during the post-implementation review of the classification and measurement requirements of IFRS 9 - Financial Instruments. The amendments are effective for reporting periods beginning on or after January 1, 2026. Santander is evaluating the impacts of this change.

· Annual Improvements to IFRS Accounting Standards - Volume 11: Includes 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 1 January 2026, with earlier application permitted. Santander is assessing the impacts of this amendment.

c.3)Estimates used

Consolidated results and the calculation of consolidated equity are impacted by accounting policies, assumptions, estimates and measurement methods used by the Bank's administrators in preparing the financial statements. The Bank makes estimates and assumptions that affect the reported values of assets and liabilities for future periods. All required estimates and assumptions, 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 explanatory note disclosures.

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 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.a&c of the Consolidated Interim Financial Statements as of September 30, 2024, 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.

* Values expresses in thousands, unless otherwise indicated.

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. Provisions, 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 Income Tax (IR) and Social Contribution (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 values of assets and liabilities and their respective calculation bases, and credits from tax losses and the negative basis of accumulated CSLL (Social Contribution on Net Profit). These values 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 utilized.

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 be used.

The recognized deferred tax assets and liabilities are reviewed at each balance sheet date, making appropriate adjustments based on the findings of the analyzes carried out. The expected realization of the Bank's deferred tax assets is based on projections of future results and based on a technical study.

* Values expresses in thousands, unless otherwise indicated.

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 quarter ended September 30, 2024, 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 September 30, 2024, 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

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 periods ended September 30, 2024 and 2023 were the following:

Balance at end of the period	41,866,465	39,471,672

* Values expresses in thousands, unless otherwise indicated.

d)Provisions for Losses of Financial Guarantee Contracts Provided

Below is the movement of these provisions for the periods ended September 30, 2024 and 2023.

c)Commitment to purchase tangible assets

As of September 30, 2024 and December 31, 2023, the Bank has no contractual commitments for the acquisition of tangible assets.

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).

Based on the assumptions described above, no loss of recoverable value of goodwill was identified on September 30, 2024. Throughout the first quarter of 2024, no indications of loss of recoverable value of goodwill were identified.

Key assumptions:
Basis for determining the recoverable amount
Period of the projections of cash flows (1)		5 years
Perpetual growth rate		5.4	%

Discount rate		13.0	%

(1) Cash flow projections are based on Management's internal budget and growth plans, considering historical data, expectations and market conditions such as industry growth, interest rates and inflation indices.

A quantitative goodwill recoverability test is performed annually. At the end of each year, an analysis is carried out regarding the existence of signs of impairment. In the period ended September 30, 2024 and fiscal year 2023 there was no evidence of impairment. In the goodwill recoverability test, discount and growth rates in 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:

* Values expresses in thousands, unless otherwise indicated.

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 - R$1,149 million (12/31/2023 - R$1,099 million) Consolidated: in May 2003, the Brazilian Federal Revenue Service issued a tax assessment notice on Santander Distribuidora de Títulos e Valores Mobiliários Ltda. (Santander DTVM) and another case at Banco Santander (Brasil) S.A. The object of the case was the collection of CPMF on operations carried out by Santander DTVM in the management of its customers' 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, Banco and Santander Brasil Tecnologia S.A. (current name of Produban Serviços de Informática S.A. and Santander DTVM) filed a lawsuit seeking to cancel both tax debts. Said action had an unfounded sentence and ruling, which led to the filing of a Special Appeal to the STJ and an Extraordinary Appeal to the STF, which are awaiting judgment. Based on the assessment of legal advisors, a provision was set up to cover the loss considered probable in the legal suit.

National Social Security Institute (INSS) - R$141 million in the Consolidated (12/31/2023 - R$138 million in the Consolidated): Banco Santander and the controlled companies discuss administratively and judicially the collection of the social security contribution and the education salary on various amounts that, according to the assessment of the legal advisors, do not have a salary nature.

Service Tax (ISS) - Financial Institutions - R$360 million in the Consolidated (12/31/2023 - R$379 million in the Consolidated): Banco Santander and its controlled companies discuss administratively and judicially the requirement, by several municipalities, for the payment of ISS on various revenues arising from operations that are not usually classify as provision of services. Furthermore, other actions involving ISS, classified as possible risk of loss, 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.

Former Banespa Employees.

Class action filed by AFABESP (an association of retired and former employees of Banespa) seeking payment of a semiannual bonus provided for in the former bylaws of BANESPA. The final decision in the action was unfavorable to Banco Santander. Therefore, each beneficiary of the decision may file an individual action to receive the amount due.

As the judgments adopted different positions for each case, a procedure called Incident of Resolution of Repetitive Demands (IRDR) was instituted before the Regional Labor Court (TRT) with the objective of establishing objective criteria regarding the theses defended by the Bank, mainly the prescriptive term and payment limitations until December 2006 (regarding the establishment of Plan V). On March 11, 2024, the IRDR incident was admitted for future judgment and the suspension of all lawsuits that are in the second instance (TRT) and filed in São Paulo (Capital) and other cities that are part of the jurisdiction of the TRT of São Paulo was determined.

Finally, due to the divergence in interpretation of the labor statute of limitations provided for in the Federal Constitution, an Action for Allegation of Non-Compliance with a Fundamental Precept (ADPF) was also filed, so that the Federal Supreme Court (STF) can resolve the issue and indicate the correct term to be used in the individual cases filed.

On June 27, 2024, a transaction was signed between Banco Santander, BANESPREV, AFABESP and legal advisors establishing criteria and conditions for the settlement of individual lawsuits. By August 23, 2024 (end of the adhesion period), approximately 90% of eligible beneficiaries had formalized their adhesion to the aforementioned transaction, which was subsequently approved by court order, and the respective individual lawsuits will be terminated. Banco Santander recorded an obligation related to the amounts actually due for payment of the transaction. (Item a,Note 10).

The other individual processes, whose beneficiaries did not adhere to the aforementioned transaction, are pending a final decision regarding the controversial legal issues, which will be resolved when the IRDR and ADPF are judged.

* Values expresses in thousands, unless otherwise indicated.

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).

However, the STF's jurisprudence has not yet been consolidated on the constitutionality of the rules that modified Brazil's monetary standard. 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.

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 and Social Security, Labor and Civil Liabilities Classified as Possible Loss Risk

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.

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.

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.

Pricing Model

The pricing model is based on the Local Volatility model or Dupire model, which allows simultaneous calibration of all quoted European options. In addition to this model, there is an extension to deal with uncertainty in dividends, where part of the dividend value is considered confirmed, and the rest is linked to the performance of the underlying. This extended model is integrated into a PDE engine, which numerically solves the corresponding stochastic differential equation to calculate the expected value of the product.

Data and assumptions used in the pricing model, including the weighted average share price, exercise price, expected volatility, option life, expected dividends and the risk-free interest rate:

•     The weighted average share price (and exercise price) is €3,104 based on the 15-day weighted average between 01/07/2022 and 01/27/2022

•     The expected volatility used was 33.80

•     Options expire on 02/01/2030

•     Expected dividends range from approximately 6.6 cents in the short term (2022) to approximately 5.75 cents per share per year in the long term (2030)

•     The discount curve used gives a discount of 0.96 for 2030

* Values expresses in thousands, unless otherwise indicated.

The exercise price, in all cycles and if the objectives established in the regulations are achieved, will be the market price on the exercise date.

Local ILP Plans (Long-Term Incentive)

Long-term incentive plans may be granted according to the strategy of new companies in the group or specific businesses.

Each plan will have a specific contract and its calculation and payment must be approved by the established governance, observing local and global regulatory resolutions.

The reference value of each participant will be converted into SANB11 shares, normally at the price of the last 15 trading sessions of the month immediately preceding the payment of the plan.

At the end of the vesting period, payment of either the resulting shares in the case of local plans or the value equivalent to the shares/options of global plans are made with a 1-year restriction, and this payment is still subject to the application of the Malus/Clawback clauses. , which may reduce or cancel the shares to be delivered in cases of non-compliance with internal regulations and exposure to excessive risks and in cases of material failure to comply with financial reporting requirements, in accordance with Section 10D, of the Exchange Act (SEC) , applicable to companies with shares listed on the NYSE.

Impact on the Result

The impacts on the result are recorded under the Personnel Expenses heading, as shown below:

		Consolidated
		01/01 to 09/30/2024	01/01 to 09/30/2023
Program	Type of Liquidation
Local	Santander Shares (Brazil)	4,384	13,149
Global	Global Stocks and Options	4,152	4,638

b)Variable Remuneration Referenced to Shares

The long-term incentive plan (deferral) determines the requirements for payment of future deferred installments of variable remuneration, considering sustainable long-term financial bases, including the possibility of applying reductions or cancellations depending on the risks assumed and fluctuations of the cost of capital.

The variable remuneration plan with payment referenced in Banco Santander shares is divided into 2 programs: (i) Identified Collective and (ii) Other Employees. The impacts on the result are recorded under the Personnel Expenses heading, as shown below:

Program	Participant	Liquidity Type	01/01 to 09/30/2024	01/01 to 09/30/2023
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)	96,230	114,449
Unidentified Collective	Other employees with variable remuneration above a minimum expected value	50% in cash indexed to 100% of the CDI and 50% instruments	117,212	151,167

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.Fair 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 September 30, 2024 and December 31, 2023, 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.2.1.i.

Management revisited the criteria assigned to classify the fair value level of assets and liabilities measured at amortized cost, presented exclusively for disclosure purposes, and concluded that they best fit into level 3 in light of observable market data.

* Values expresses in thousands, unless otherwise indicated.

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 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 determines that financial institutions must maintain a Reference Equity (PR), PR Level I and Main 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 portions, market risk and operational risk.

As established in CMN Resolution No. 4,958/2021, the PR requirement is 11.50%, including 8.00% Minimum Reference Equity, plus 2.50% Capital Conservation Additional and 1.00% Additional Systemic. The PR Level I is 9.50% and the Minimum Principal Capital is 8.00%. Continuing with the adoption of the rules established by CMN Resolution No. 4,955/2021, the calculation of capital indices is calculated in a consolidated manner based on information from the Prudential Conglomerate, the definition of which is established by CMN Resolution No. 4,950/2021, as demonstrated in follow:

	09/30/2024	12/31/2023
Level I Reference Assets	90,633.1	81,259.1
Main Capital	75,809.0	75,042.8
Additional Capital	14,824.0	6,216.3
Level II Reference Equity	14,938.1	13,644.2
Reference Heritage (Level I and II)	105,571.2	94,903.3
Credit Risk (1)	585,689.8	560,780.9
Market Risk (2)	44,007.0	33,002.7
Operational Risk	60,643.3	60,491.1
Total RWA (3)	690,340.1	654,274.7
Basel Index Level I	13.13	12.43
Basel Core Capital Index	10.98	11.48
Basel Reference Equity Index	15.29	14.51

(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. 2/20, considering market information and scenarios that would negatively affect the Bank's positions.

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:

	09/30/2024	12/31/2023
Funds under management	240,444	11,871,919
Managed funds	241,797,898	291,736,828

(Banco Santander or Bank) for the period ended September 30, 2024, prepared in accordance with the 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®). They will be published on October 30, 2024 at the email address www.santander.com.br/ri.

1. Economic Situation

Economic performance was highlighted by the following themes:

In the international environment

vChange in the scenario of the presidential elections in the USA due to the withdrawal of the current president, Joe Biden, and replacement by his vice-president, Kamala Harris.

vIntensification of tensions in the Middle East with the involvement of several nations in the region in conflicts between Israel and the Palestine region.

vRising interest rates in Japan signal the continuation of the future upward trajectory, significantly impacting asset prices around the globe.

vReduction in interest rates in the US above the expectations of most markets, raising doubts about the magnitude of the new cuts ahead.

vAnnouncement of monetary stimuli by the Chinese authorities with the aim of increasing the country's economic growth rate.

In the domestic environment

Worsening expectations regarding the evolution of Brazilian public debt resulting from frustration with the bimonthly budget review.

Given the involvement of the majority of parliamentarians in the municipal elections, no substantial progress was observed in relevant projects such as the conclusion of the Tax Reform or the proposal to renegotiate state debts.

The slowdown in the evolution of such agendas and the absence of relevant measures in this regard contribute to increased market skepticism regarding the dynamics of public accounts.

Despite tax collection continuing to record robust performance in the third quarter of 2024, public spending also demonstrated a strong pace of growth - and in a more structural way than the evolution of revenues.

This combination reinforces the negative perception of the markets regarding the trajectory of Brazilian public debt for the coming years, a situation worsened by the bimonthly budget review that took place in September, which reduced the amount of contingent expenditure in July, making it difficult to improve the prices of domestic assets.

After fluctuations between R$5.00/US$ and R$5.60/US$ in the second quarter of 2024, the variation range changed level, with the exchange rate of the Brazilian currency against the US dollar fluctuating between R$5.37 /US$ and R$5.86 /US$ in the third quarter. However, the exchange rate ended the period at R$5.59/US$, the same level seen at the end of 1Q24. In Banco Santander's view, the worsening perception regarding Brazilian fiscal dynamics was the main reason for the devaluation of the real, since most of the international highlights that occurred in the period indicated a favorable influence on the real.

Banco Santander assesses that the prospect of additional increases in the Selic rate in the coming months, the maintenance of a very solid performance in foreign trade and the signs that the interest rate cut cycle in the USA is expected to extend throughout 2025 could help the real ahead. For these reasons, we project that the exchange rate will end 2024 at around the level of R$5.40/US$.

PGDP performance in the 2nd quarter of 2024 above expectations, despite the damage caused by the floods in Rio Grande do Sul.

Signaled by the median of market projections, GDP performance in 2Q24 surprised positively and once again recorded strong growth in the period. In Banco Santander's opinion, the performance continued to be largely the result of the resilience of the labor market together with the extension of fiscal stimuli. This result ended up reinforcing the wave of upward revisions in the projection for GDP growth in 2024. At the end of 2Q24, the median of economic agents' projections regarding the performance of the Brazilian economy indicated Brazilian GDP growth of 2.1% in 2024. At the end of 3Q24, the median projections rose to 3.0%. Banco Santander also revised its projection from 2.0% to 3.0% in the same comparison, with the state of Rio Grande do Sul showing recovery from the impacts of the floods more quickly than imagined.

Continued deterioration in inflation expectations and climate factors affecting prices in the short term led to the resumption of the interest rate hike cycle.

Although the interannual variation of the IPCA remained at a level below the ceiling of the tolerance margin stipulated by the inflation targeting system, the underlying inflation measures continued to indicate difficulty in converging to the 3.0% target over the relevant time horizon for the monetary policy. Together with the worsening perception of the dynamics of public spending in the months ahead and climatic factors that negatively influenced energy and food prices in the short term, these factors ended up causing inflationary expectations for the coming years to worsen further. At the end of 2Q24, inflation expectations for the years 2024 and 2025 were, respectively, 4.00% and 3.87%. At the end of 3Q24, expectations for the same periods reached 4.36% and 3.97%, respectively. As a result, the Central Bank opted to resume the interest rate hike cycle in September 2024 and, in addition, signaled that it will be necessary to raise the Selic rate level to a level well above the 10.50% it has maintained until then in order for there to be the convergence of the interannual variation of the IPCA towards the target of 3.0%. Although Banco Santander assesses that inflationary dynamics should improve over the next few months, the institution understands that it will be difficult to achieve a substantial improvement in inflationary expectations in light of so many uncertainties present in the domestic and international spheres – a key factor in resuming the reduction process interest rates in Brazil. For this reason, Banco Santander projects that the Selic rate will reach 11.75% p.a. until the end of 2024 and will continue to rise in the first two Copom meetings in 2025, reaching a peak of 12.50% in March of next year.

2. Consolidated Performance

We maintained our continuous evolution towards resuming higher levels of profitability. The financial margin showed an evolution guided by the strategy of qualified and selective growth, directing efforts towards assets with better return on capital. Commissions maintained a positive trajectory, reflecting a greater diversification of our revenue sources. We maintained the good quality of our credit portfolio, which reinforces a positive trajectory for 2024, with controlled default rates. Regarding efficiency, we remain focused on further consolidating our culture of productivity. We continue to advance in building a solid, less volatile balance sheet with the capacity to generate sustainable results.

4. Corporate Governance

The Governance structure of Banco Santander Brasil is integrated by the Executive Board and its Executive Committee made up of the Chief Executive Officers, Senior Executive Vice-Presidents and Executive Vice-Presidents, and by the Board of Directors and its Advisory Committees, they are: Audit, Risks and Compliance, Sustainability, Remuneration and Appointment and Governance.

For more information on the corporate governance practices adopted by Banco Santander Brasil and the deliberations of the Board of Directors, see the website www.santander.com.br/ri.

5. Internal Audit

Internal Audit reports directly to the Board of Directors, with the Audit Committee responsible for its supervision.

Internal Audit is a permanent function independent of any other function or unit, whose mission is to provide the Board of Directors and senior management with independent assurance on the quality and effectiveness of internal control and risk management processes and systems (current or emerging) and government, thus contributing to protecting the value of the organization, its solvency and reputation. Internal Audit has a quality certificate issued by the Institute of Internal Auditors (IIA).

To fulfill its functions and coverage risks inherent to Banco Santander's activity, Internal Audit has a set of tools developed internally and which are updated when necessary. Among them, the risk matrix stands out, used as a planning tool, prioritizing the risk level of the auditable universe considering, among others, its inherent risks, the last audit rating, the degree of compliance with recommendations and their dimension. The work programs, which describe the audit tests to be carried out, are reviewed periodically.

The Audit Committee and the Board of Directors favorably analyzed and approved the Internal Audit work plan for the year 2024.

6. People

Banco Santander continues to strengthen its organizational culture and its obsession with evolving the client and employee experience. Protagonism and autonomy increase in favor of an environment of innovation that accelerates digital transformation and improves the offer for the most diverse segments of society.

There are 55,035 employees, considering the entire group, committed to the ambition of making Santander the main bank for each of its clients.

To this end, Santander values a diverse environment, in which each professional feels valued and builds their career with a long-term vision. Based on 5 pillars of diversity - Female Leadership; Racial Equity; Disabled people; Generational Diversity and LGBTQIA+ and the transformative force of continuous learning, each employee is the protagonist of their development journey, enriched by essential collaboration between peers and leaders, ensuring that growth opportunities are available to everyone. Santander was once again elected as one of the Best Companies to Work for in Brazil by GPTW, occupying 8th position in the national ranking of companies with more than 10,000 employees and 2nd place in the Sector Ranking of Large Banks.

7. Sustainability

Our history in sustainability began more than 20 years ago. Throughout this period, we have experienced an intense journey of evolution, in which we have improved our programs, businesses and governance focused on the topic.

In this trajectory, we highlight the assessment and mitigation of social, environmental and climate risks for granting credit to projects and companies; generating businesses that support customers’ transition to a low-carbon economy; and the construction of a more inclusive society, through education and employability, financial inclusion and entrepreneurship and social inclusion actions. Many of these initiatives are accompanied by global targets in the areas where we have the greatest potential impact, such as net zero, financial inclusion and diversity.

To ensure good governance of this process, we have robust policies and controls, supported by senior leadership.

At the end of 3Q24, we highlight the following results:

Environmental:

vWe made R$22.6 billion viable in sustainable businesses and achieved a portfolio of R$35.3 billion in green bond issues, clean energy financing and dedicated product options. vAmong them is Prospera Santander Microfinanças, which since 2002 has been providing financial solutions to entrepreneurs. In the last quarter, we reached approximately R$3.2 billion in portfolio, an increase of 8.22% and we have 1.1 million customers from more than 1,700 communities in the country. vWe published our Emissions Inventory in the Public Emissions Registry, a Brazilian platform for publishing inventories of greenhouse gas (GHG) emissions from organizations participating in the Brazilian GHG Protocol Program.

Promoting sustainable businesses with a commitment to being Net Zero by 2050

Social:

v Through Santander Universities, we registered 108.5 thousand people who benefited from courses and scholarships, which amounted to an investment of R$16.8 million (+19.8%). v We are in the new Idiversa B3 portfolio, launched in August. This is the first index focused on diversity in Latin America, of which we have been part since 2022. v We have a new Volunteer Program, which mobilizes around 600 employees, who work on financial education, professional development and actions with children, teenagers and the elderly. One example is the training of outsourced service providers in some administrative buildings to work in the marketing of financial products.

Contribution to building a more inclusive society, with access to education and financial products.

Governance:	v Our Board of Directors currently has 45% female members and 55% independent members.
Promotion of ESG in our culture, through the connection of all Banco Santander businesses.

8. Independent Audit

The operating policy of Banco Santander, including its controlled companies, in contracting services not related to the audit of the Financial Statements by its independent auditors, is based on Brazilian and international auditing standards, which preserve the independence of the auditor. This rationale provides for the following: (i) the auditor should not audit his own work, (ii) the auditor should not perform managerial functions for his client, (iii) the auditor should not promote the interests of his client, and (iv ) need for approval of any services by the Bank's Audit Committee.

In compliance with Securities and Exchange Commission Instruction 162/2022, Banco Santander informs that in the period ended September 30, 2024, no services unrelated to the independent audit of the Financial Statements of Banco Santander and controlled companies were provided by PricewaterhouseCoopers. Furthermore, the Bank confirms that PricewaterhouseCoopers has procedures, policies and controls to ensure its independence, which include the evaluation of the work provided, covering any service that is not independent auditing of the Financial Statements of Banco Santander and controlled companies greater than 5% of the total fees relating to independent audit services. This assessment is based on applicable regulations and accepted principles that preserve the auditor's independence. The acceptance and provision of professional services not related to the audit of the Financial Statements by its independent auditors during the period ended March 31, 2024, did not affect the independence and objectivity in the conduct of external audit examinations carried out at Banco Santander and other entities of the Group, since the principles indicated above were observed.

9. Acknowledgement

We would like to thank our customers, shareholders and employees for the trust and support that got us here, and that enabled the continuity of our story of evolution and transformation, on the path to building the Best Consumer Company in Brazil.
