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 consolidated condensed balance sheet of Banco Santander (Brasil) S.A. ("Bank") and its subsidiaries as at September 30, 2023 and the related consolidated condensed statements of income and comprehensive income for three and nine-months then ended, and changes in stockholders' equity and cash flows for nine-months 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 ofreview

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).

Other matters

Condensed statement ofValue Added

The consolidated condensed interim financial statements referred to above include the consolidated condensed statement of value added for nine-months ended September 30, 2023, prepared under the responsibility of the Bank's management and presented as supplementary information 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.

1. Operating context, presentation of condensed consolidated interim

financial statements and other information

a) Operational Context

Banco Santander (Brasil) S.A. (Banco Santander or Banco), directly and indirectly controlled by Banco Santander, S.A., headquartered in Spain (Banco Santander Spain), is the leading institution of the Financial and Prudential Conglomerates (Santander Conglomerate) before the Central Bank of Brazil (Bacen), constituted as a joint-stock company, headquartered at Avenida Presidente Juscelino Kubitschek, 2041, Cj.281, Bloco A, Cond. JK Tower – Vila Nova Conceição – São Paulo - SP. Banco Santander operates as a bank multiple and develops its operations through the commercial, investment, credit, financing and investment, real estate credit, leasing and foreign exchange. Through controlled companies, it also operates in the markets of payment institution, syndicate management, securities brokerage, insurance brokerage, loan financing consumption, digital platforms, benefit management, management and recovery of non-performing loans, capitalization and pension plans and supply and administration of food, meal and other vouchers. Operations are conducted in the context of a set of institutions that operate in an integrated manner in the financial market. The benefits and costs corresponding to the services provided are absorbed between them and are carried out in the normal course of business and under commutative conditions. The Board of Directors authorized the issuance of condensed consolidated interim financial statements for the period ended September 30, 2023 at the meeting held on October 24, 2023.

The referred Financial Statements and the documents that compose them, were subject to a report without reservation by the Auditors Independent, of recommendation for approval issued by the Audit Committee of Banco Santander.

b) Presentation of condensed consolidatedinterim financial statements (prepared in accordance with IAS 34)

The Condensed Consolidated Interim Financial Statements have been prepared in accordance with International Financial Reporting Standards (IFRS) issued by the International Accounting Standards Board (IASB), and the interpretations issued by the IFRS Interpretations Committee (current name of the International Financial Reporting Interpretations Committee – IFRIC). All relevant information specifically relating to Banco Santander's financial statements, and only with respect to these are being evidenced, and correspond to the information used by Banco Santander in its administration.

For better comparison purposes, some comparative balances were reclassified in the statement of cash flows relating to the result of financial guarantees provided, effects of changes in exchange rates on assets and liabilities and reduction (increase) in other financial assets and liabilities.

c) Other information

c.1)Adoption of new standards and interpretations

The following amendments to standards were adopted for the first time for the financial year beginning January 1, 2023:

• IFRS 17 - In May 2017, the IASB issued the IFRS for insurance contracts which aims to replace IFRS 4. From January 1, 2023. This standard aims to provide greater transparency and ensure that an entity presents relevant information and that faithfully represents the essence of insurance operations in the financial statements, one of the main changes being the recognition of profits as a measure of the delivery of insurance services. Banco Santander assessed and concluded that the impact of adopting IFRS 17 is immaterial.

**· Amendment to IAS 1 "Presentation of Financial Statements”:**the purpose is to clarify that liabilities are classified as current or non-current, depending on the rights that exist at the end of the period. The ranking is not affected by the entity's expectations or events after the reporting date. The amendments to IAS 1 are effective as of January 1, 2023 and there is no impact for Santander.

· Amendment to IAS 8 - Accounting Policies, Estimate Changes and Error Rectification: clarifies how entities should distinguish changes in accounting policies from changes in accounting estimates, since changes in estimates accounting principles are applied prospectively to future transactions and other future events, but changes in accounting policies are generally applied retrospectively to past transactions and other past events, as well as to the current period. Without impact for Santander

· Amendment to IAS 12- Income Tax: requires entities to recognize deferred tax on transactions that, on initial recognition, give rise to equal amounts of taxable and deductible temporary differences. This usually applies to lease transactions (right-of-use assets and lease liabilities) and decommissioning obligations and restoration, as an example, and will require the recognition of additional deferred tax assets and liabilities. Santander already adopts this procedure.

· Amendment to IAS 21- Effects of Changes in Exchange Rates and Conversion ofFinancial 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.

There are no other IFRS standards or IFRIC interpretations that have not yet come into force that could have a significant impact on the Bank's financial statements.

c.2) Estimates used

Consolidated results and calculation of consolidated equity are impacted by accounting policies, assumptions, estimates and measurement methods used by the Bank's managers in preparing the financial statements. the bank does estimates and assumptions that affect the reported amounts of assets and liabilities for future periods. All estimates and assumptions required, in accordance with IFRSs, are Management's best estimate in accordance with the applicable standard.

In the condensed consolidated interim financial statements, estimates are made by the Bank's Management and of consolidated entities in order to quantify certain assets, liabilities, income and expenses and disclosures in the notes.

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 in the disclosures of explanatory notes, are described below:

i. Valuationof 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 prevailing 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 between Levels I, II or III.

Note 18.b of the Consolidated Interim Financial Statements as of September 30, 2023, presents the accounting practice and sensitivity analysis for the Financial Instruments, respectively.

ii. Provisionsfor losses on credits due to impairment

The carrying amount of impaired financial assets is adjusted by recording a provision for impairment of “Losses on financial assets (net) – Financial Assets measured at amortized cost” in the consolidated statement of income result. The reversal of previously recorded losses is recognized in the consolidated statement of income in the period in which the impairment decreases and can be objectively related to a recovery event.

To individually measure the impairment loss on loans assessed for impairment recoverable, the Bank considers the conditions of the counterparty, such as its economic and financial situation, level of indebtedness, income generation capacity, cash flow, management, corporate governance and quality of internal controls, track record payment terms, industry experience, contingencies and credit limits, as well as asset characteristics such as their nature and purpose, type, sufficiency and guarantees of liquidity level and total amount of credit, and also based on historical experience of impairment and other circumstances known at the time of valuation.

To measure the impairment loss on loans that are collectively assessed for impairment, the Bank separates financial assets into groups taking into account the characteristics and similarities of credit risk, or that is, according to the segment, type of assets, guarantees and other factors associated with the historical experience of write-down recoverable and other circumstances known at the time of valuation.

Note 6 to the Consolidated Interim Financial Statements of September 30, 2023, presents the accounting practice and credit risk measurement measures, respectively.

iii. Provisionsfor pension funds

Defined benefit plans are registered based on an actuarial study, carried out annually by a specialized company, end of each year, effective for the subsequent period and are recognized in the consolidated income statement in the Interest and similar expenses and Provisions (net) lines.

The present value of a defined benefit obligation is the present value without deducting any plan assets, payments expected from future periods necessary to settle the obligation resulting from the employee's service in the current and past periods.

iv. Provisions,assets and contingent 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 registered goodwill is subject to an impairment test, at least once a year or in a shorter period, in case of any indication of impairment of the asset.

The basis used for the impairment test is the value in use and, for this purpose, the cash flow is estimated for a period minimum of 5 years. The cash flow was prepared considering several factors, such as: (i) macroeconomic interest rate projections, inflation, exchange rate and others; (ii) behavior and growth estimates of the national financial system; (iii) increase in costs, returns, synergies and investment plan; (iv) customer behavior; and (v) growth rate and adjustments applied to perpetuity flows. The adoption of these estimates involves the probability of occurrence of future events and the change of any of these factors could have a different outcome. The cash flow estimate is based on a valuation prepared by the company independent expert, annually or whenever there are signs of a reduction in its recovery value, which is reviewed and approved by the Administration.

Additional details are in note 7.

vi. Expectationof realization of 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 tax loss credits and the negative basis of the accumulated CSLL. 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 assets deferred taxes 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 use.

Recognized deferred tax assets and liabilities are reviewed at each balance sheet date, making adjustments appropriate 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 technical study.

b)Valuation adjustments arising from impairment of financial assets

b.1) Financial assets measured at fair value through OtherComprehensive Income

As indicated in explanatory note 2 to the Bank's consolidated Interim Financial Statements for the quarter ended September 30, 2023, changes in the carrying amount of financial assets and liabilities are recognized in the statement consolidated statement of income and except in the case of financial assets measured at fair value through other comprehensive income, in which changes in fair value are temporarily recognized in consolidated equity, under “Other income comprehensive”.

Debits or credits in "Other Comprehensive Income" arising from changes in fair value, remain in equity consolidated net income of the Bank until the respective assets are derecognized, when they are recognized in the statement consolidated result. As part of the fair value measurement process, when there is evidence of impairment losses of these instruments, the amounts are no longer recognized in shareholders' equity under the caption "Financial Assets Measured at Fair Value through Other Comprehensive Income” and are reclassified to the Consolidated Statement of Income at cumulative value on that date.

On September 30, 2023, 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 arising from impairment losses (impairment). Consequently, all changes in the fair value of these assets are presented in "Other Income Comprehensive”. Changes in the balance of other comprehensive income in the interim period are recognized in the statement Consolidated Other Comprehensive Income.

In the second quarter of 2022, in accordance with the best corporate governance practices, Management approved the change in the business model of bonds and securities held for the purpose of collecting contractual cash flows and sell to held with the objective of collecting contractual cash flows, in the amount of R$ 11 billion with no impact on result, with the balance in Equity reversed in full.

This decision is based on a response to changes brought About by the approval of Law 14.031/20 and, with the aim of adapting the new interest rate risk management conditions, the pre-fixed government securities LTNs that were used to cover the interest differential were reclassified on April 1, 2022. Such change in legislation entails changing the Model of Management used by Management to manage these securities, and it is estimated that the LTNs maturing in 2024 do not fit more in “Kept to Collect and Sell” models, and with the extinction of the fiscal asymmetry of investments abroad, such securities will be used exclusively for purposes of collecting cash flows.

Thus, with the reclassification carried out on April 1, 2022, the Federal Public Securities - LTNs maturing in 2024 are no longer recorded at Fair Value in Other Comprehensive Income, and become effective for Principal Payment Only and Interest. This event results in the full reversal of the mark-to-market amount recorded in Other Comprehensive Income on the reclassification date in the gross total of R$ 1,025 million, reducing, on the other hand, the value of the registered asset.

b.2) Financial assets measured at amortized cost - loans, otheramounts with credit institutions and advances to customers

c) Tangibleasset purchase commitments

As of September 30, 2023, the Bank has no contractual commitments for the acquisition of tangible assets (12/31/2022 – R$ 50,047)

7. Intangible

assets - Goodwill

The goodwill constitutes the surplus between the acquisition cost and the Bank's participation 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 income. In accordance with IFRS 3 Business Combinations, goodwill is accounted for at cost and is not amortized, but tested annually for impairment purposes or whenever there are indications of impairment of the cash-generating unit to which he was allocated. Goodwill is accounted for at cost less accumulated impairment losses. Impairment losses recognized on goodwill are not reversed. Gains and losses on disposal of an entity include the carrying amount of goodwill relating to the entity sold.

The goodwill recorded is subject to the impairment test (note 1.c.2.1.v) and was allocated according to the operating segment (note 15).

Based on the assumptions described above, no impairment of goodwill was identified on S eptember 30, 2023. Throughout the third quarter of 2023, no indication of impairment of goodwill was identified.

Key assumptions:
Basis for determining the recoverable amount
Period of the projections of cash flows (1)		5 years
Perpetual growth rate		5.1%
Discount rate (2)		12.9%

(1) The projections of cash flow are prepared using Management´s growth plans and internal budget, based on historical data, market expectations and conditions such as industry growth, interest rate and inflation.

(2) The discount rate is calculated based on the capital asset pricing model (CAPM). The discount rate before tax on December 31, 2022 was 19.09%.

A quantitative goodwill recoverability test is performed annually. At the end of each financial year, an analysis is carried out regarding the existence of accusations of impairment. In the period ended September 30, 2023 and fiscal year 2022 there was no evidence of impairment. In the goodwill recoverability test, discount and growth rates in perpetuity are the most sensitive bets for calculating the present value (value in use) of discounted future cash flows. With a variation of +0.25% or -0.25% in these rates, the value of future cash flows discounted to present value continues to indicate the non-existence of impairment.

b) Tax, Social Security, Labor and CivilProvisions

Banco Santander and its subsidiaries are an integral part of legal and administrative proceedings of a tax, social security, labor and civil nature, arising in the normal course of their activities.

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

Management understands that the provisions set up are sufficient to cover possible losses arising from legal and administrative proceedings as follows:

b.1)Lawsuits and Administrative Proceedings – related to Tax and Social Security

Mainjudicial and administrative proceedings with probable risk of loss

Banco Santander and its subsidiaries are parties to judicial and administrative proceedings related to tax and social security disputes, which are classified, based on the opinion of legal advisors, as a probable risk of loss.

ProvisionalContribution on Financial Transactions (CPMF) in Customer Operations: R$1,079,014 (12/31/2022 - R$1,016,253) in the Bank and Consolidated: in may 2003, the Federal Revenue Service of Brazil issued a notice of infraction on Santander Distribuidora de Títulos e Valores Mobiliários Ltda. (Santander DTVM) and another notice 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' funds and clearing services provided by the Bank to Santander DTVM, which occurred during the years 2000, 2001 and 2002. The administrative process ended unfavorable 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 annul both tax debts. Said action had an unfounded sentence and judgment, which gave rise to the filing of a Special Appeal with the STJ and an Extraordinary Appeal with the STF, which is awaiting judgment. Based on the assessment of the legal advisors, a provision was set up to cover the loss considered probable in the lawsuit.

National Social Security Institute (INSS) - R$137,082 in the Consolidated (12/31/2022 - R$133,593 in the Consolidated): Banco Santander and the subsidiaries are discussing administratively and judicially the collection of the social security contribution and the education allowance on various sums that, according to the assessment of the legal advisors, are not have salary nature

Tax on Services (ISS) - Financial Institutions R$380,106 in the Consolidated (12/31/2022 - R$319,020 in the Consolidated): Banco Santander and its subsidiaries are administratively and judicially discussing the requirement, by several municipalities, of the payment of ISS on various revenues arising from operations that are usually not classified as provision of services. In addition, other lawsuits involving ISS, classified as a possible risk of loss, are described in note 10.b.4.

b.2)Judicial and Administrative Proceedings of a Labor Nature

These are lawsuits filed by Trade Unions, Associations, the Public Ministry of Labor and former employees claiming labor rights

they understand 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 lawsuits closed. Shares that do not fit the previous criteria are provisioned according to the individual assessment carried out, provisions being constituted based on the probable risk of loss, in law and case law in accordance with the assessment of loss carried out by legal advisors.

FormerEmployees of Banespa. Action distributed in 1998 by the Association of Retirees of Banespa (AFABESP) requesting the payment of half-yearly bonus provided for in Banco Banespa's regulations for approximately 8,400 former employees (retirees), according to which the payment will be made in the event that the Bank makes a profit and the distribution of this profit is approved by the board of directors. The bonus was not paid in 1994 and 1995 because the Banespa bank did not make a profit during these years. Partial payments were made between 1996 and 2000 as approved by the board of directors. The mentioned clause was excluded from the regulation in 2001. The Regional Labor Court and the Superior Labor Court condemned Santander Brazil, as the successor of Banespa, to pay the half-yearly bonus for the periods relating to the second half of 1996 and semesters of 1997. On March 20, 2019, a decision by the Federal Supreme Court (Supremo Tribunal Federal, or “STF”) rejected the extraordinary appeal filed by Banco Santander, which did not resolve the merits of the case. We filed a rescission action to annul the sentence due to AFABESP's lack of legitimacy (according to precedent No. 573,232 of the STF) or to recognize the nullity of the TRT judgment that did not summon Banco Santander About the modifying effects of the decision, as well as to suspend execution in the main process. The rescission action was dismissed, and this decision was opposed by Embargoes de Clarification, due to the absence of an explicit manifestation About the arguments brought by the Bank. About the Embargoes de Clarification the omission points were not answered as required by law, which is why it was filed Extraordinary Appeal that was denied by the TST. The Bank filed an appeal against this decision, which is pending admissibility, bearing in mind that the decisions handed down by the Superior Labor Court are contrary to an already peaceful position in the STF (precedent No. 573.232), according to which the Association needs a specific power of attorney to sue in court, and also the decision affronts constitutional precepts regarding access to justice (item XXXV of article 5 of CF) by determining payment excessive costs. Regarding the main action, in August 2021, a decision was handed down that determined that the execution be carried out individually in the corresponding forum of each defendant and AFABESP filed an appeal that was dismissed, reason why the decision became final.

Our legal advisors classified the risk of loss as probable. The current decisions of the court, and neither of the main proceedings, do not define a specific amount to be paid by those replaced, and the amounts must be determined on a regular basis sentence liquidation, which is why approximately 7.2 thousand individual compliance actions have already been distributed collectively.

On September 30, 2023, the provision is constituted based on the estimated probable loss of the individual lawsuits against the Bank

b.3)Judicial and Administrative Proceedings of a Civil Nature

These provisions are in general arising from: (1) lawsuits requesting revision of contractual terms and conditions or requests for monetary adjustments, including alleged effects of the implementation of various government economic plans, (2) lawsuits arising from financing agreements, (3) enforcement actions; and (4) claims for damages. For civil claims considered common and similar in nature, provisions are recorded based on the historical average of closed cases. Claims that do not meet the above criteria are provisioned according to an individual assessment carried out, and provisions are set up based on the probable risk of loss, in law and case law, in accordance with the assessment of loss made by the legal advisors.

The main proceedings classified as a probable risk of loss are described below:

Actionsof an Indemnity Nature - Refers to compensation for material and/or moral damages, related to the consumer relationship, dealing mainly with issues relating to credit cards, direct consumer credit, current accounts, collection and loans and other matters. In lawsuits related to causes considered similar and usual for the business, in the normal course of the Bank's activities, the provision is set up based on the historical average of closed lawsuits. Claims that do not meet the above criteria are provisioned according to an individual assessment carried out, and provisions are set up based on the probable risk of loss, in law and case law, in accordance with the assessment of loss made by the legal advisors.

EconomicPlans - They refer to judicial discussions, which claim alleged inflationary purges arising from Economic Plans (Bresser, Verão, Collor I and II), as they understand that such plans violate acquired rights related to the application of inflationary indices supposedly due to Savings Accounts, Judicial Deposits and Time Deposits (CDBs). The lawsuits are accrued based on the individual assessment of loss made by the 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 the Public Defender's Office. The constitution of a provision is made only for cases with probable risk, based on the requests for individual executions. The matter is still under analysis by the STF. There is jurisprudence in the STF favorable to the 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 (tablita).

However, the jurisprudence of the STF has not yet been consolidated on the constitutionality of the norms that modified the monetary standard in Brazil. On April 14, 2010, the Supreme Court of Justice (STJ) decided that the deadline for filing public civil actions that discuss the purges is 5 years from the date of the plans, but this decision has not yet become final. Thus, with this decision, a large part of the actions, as they were proposed after the 5-year period, will probably be dismissed, reducing the amounts involved. The STJ also decided that the deadline for individual savers to qualify in Public Civil Actions is also 5 years, counted from the final and unappealable decision 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 Attorney General's Office (AGU), Bacen, the Consumer Protection Institute (Idec), the Brazilian Savings Front (Febrapo) and the Brazilian Federation of Banks (Febraban) signed an agreement that seeks to end the legal disputes over the Economic Plans.

Discussions focused on defining the amount that would be paid to each author, according to the balance in the booklet on the date of the plan. The total amount 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 term of agreement negotiated between the parties was ratified by the STF.

In a decision handed down by the STF, there was a national suspension of all processes that deal with the issue for the duration of the agreement, with the exception of cases in final compliance with the sentence.

On march 11, 2020, the agreement was extended by means of an amendment, with the inclusion of actions that only involve the discussion of Plano Collor I. Such extension has a period of 5 years and the ratification of the terms of the amendment took place on the 3rd of june 2020.

b.4) Contingent Tax and Social Security, Labor and CivilLiabilities Classified as Risk of Possible Loss

These are judicial and administrative proceedings of a tax and social security, labor and civil nature classified, based on the opinion of the legal advisors, as a possible risk of loss, therefore not being provisioned.

Tax lawsuits classified as a possible loss totaled R$33,631 million in Consolidated (12/31/2022 - R$31,522 million), the main processes being the following:

PISand 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. On September 30, 2023, the amount involved is R$2,080 million. For other legal actions, the respective PIS and COFINS obligations are established.

INSS on Profit Sharing (PLR)- the Bank and its subsidiaries have legal and administrative proceedings resulting from questioning by the tax authorities, regarding the collection of social security contributions on payments made as profit sharing. As of September 30, 2023, amounts related to these proceedings totaled approximately R$8,797 millions.

Tax onServices (ISS) - Financial Institutions- Banco Santander and its subsidiaries are challenging administratively and judicially the requirement, by several municipalities, to pay ISS on various revenues arising from operations that are not usually classified as services rendered. As of September 30, 2023, the amount was approximately R$5,120 million.

UnapprovedCompensation – the Bank and its affiliates are discussing administratively and judicially with the Federal Revenue Service the non-approval of tax offsets with credits resulting from overpayment or undue payment. As of September30, 2023, the amount was approximately R$4,634 million.

Amortizationof Banco Real Goodwill – the Federal Revenue of Brazil issued a notice of infraction against the Bank to demand the payments of IRPJ and CSLL, including arrears charges, referring to the base period of 2009. The Tax Authorities considered that the goodwill related to the acquisition of Banco Real, amortized in the accounting before its incorporation, could not be deducted by Banco Santander for tax purposes. The notice of infraction was duly contested and we are currently awaiting judgment before the CARF. On September 30, 2023, the amount was approximately R$1,617 million.

Losseson Credit Operations - the Bank and its subsidiaries contested the tax assessments issued by the Federal Revenue Service of Brazil alleging the undue deduction of losses on credit operations from the IRPJ and CSLL calculation bases for allegedly not meeting the requirements of applicable laws. As of September 30, 2023, the amount related to this dispute is approximately R$1,864 million.

Use ofCSLL Tax Losses and Negative Base – Infraction notices drawn up by the Federal Revenue Service of Brazil in 2009 for alleged undue compensation of tax losses and CSLL negative base, as a result of tax assessments drawn up in previous periods. Judgment at the administrative level is awaited. On September 30, 2023, the amount was R$1,211 million.

Amortizationof Banco Sudameris Goodwill – the tax authorities issued tax assessment notices to demand payment of IRPJ and CSLL, including arrears charges, referring to the tax deduction of the amortization of the goodwill paid in the acquisition of Banco Sudameris, referring to the base period from 2007 to 2012. Banco Santander presented the respective administrative defenses, which were judged unfavorably. Currently, the lawsuits are awaiting judgment at the CARF. On September 30, 2023, the amount was approximately R$734 million.

IRPJ and CSLL - CapitalGain -the Federal Revenue Service of Brazil issued a notice of infraction against Santander Seguros (legal successor of ABN AMRO Brasil Dois Participações S.A. (AAB Dois Par) charging income tax and social contribution related to the 2005 fiscal year. Brasil alleges that the capital gain on the sale of the shares of 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%. based on the understanding that the tax treatment adopted in the transaction was in compliance with current tax legislation and the capital gain was duly taxed. The administrative process ended unfavorably for the Company. In July 2020, the Company filed a lawsuit seeking to cancel the debt. The lawsuit awaits judgment. Banco Santander is liable for any adverse outcome in this lawsuit as the former controlling shareholder of Zurich Santander Brasil Seguros e Previdência S.A. As of September 30, 2023, the amount was approximately R$543 million.

IRRF- Foreign Remittance – The Company filed a court order seeking to avoid taxation of the Withholding Income Tax - IRRF on income derived from the provision of services performed by a company abroad, as they do not involve transfer of technology, due to the existence of International Treaties signed between Brazil- Chile; Brazil-Mexico and Brazil-Spain, avoiding double taxation – DTTs. In July 2013, in junective relief was granted to suspend the enforceability of the amounts, and therefore, the judgment prevailed. Currently, the lawsuit awaits judgment at the Federal Regional Court of the 3rd Region. As of September 30, 2023, the amount was approximately R$885 million.

Labor claims classified as a possible loss totaled R$209 million in the Consolidated, including the process below:

The sentence granted the correction, but only in periods in which no other form of adjustment was applied. The Bank and Banesprev appealed this decision and the appeals were dismissed, which is why a Special and Extraordinary Appeal were filed, both pending judgment. In Provisional Execution, calculations were presented by the Bank and Banesprev due to the exclusion of participants who, among other reasons, are listed as plaintiffs in other actions or have already had some type of adjustment. The amount involved is not provisioned considering that there is no list of represented parties duly approved in the records, and the execution remains suspended.

Liabilities related to civil lawsuits with a possible risk of loss totaled R$2,830 million in Consolidated, with the following main lawsuits:

IndemnificationAction Regarding Custody Services -provided by Banco Santander in the expert phase and still without a sentence issued

GlobalILP Plans

We currently have 4 global plans launched in 2019, 2020, 2021 and 2022. Eligible executives have target incentives in shares and options from Grupo Santander (SAN), with payment after a deferral period of three years and settlement of the sale value donates assets in reais.

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 weighted average share price, exercise price, expected volatility, option life, expected dividends and risk-free interest rate:

• Weighted average share price (and strike price) is €3,104 based on the 15-day weighted average between 7/1/2022 and 1/27/2022

• 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

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.

Long-TermIncentive Plans (ILP)

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 normative 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 plan's payment.

At the end of the vesting period, payment either for the resulting shares in the case of local plans, or for the amount equivalent to the shares/options of the global plans are made with a 1-year restriction, 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 rules and exposure to excessive risks.

Impacton Result

The impacts on income are accounted for under Personnel Expenses, as follows:

		Consolidated
		01/01 to 09/30/2023	01/01 to 09/30/2022
Program	Liquidity Type
Local	Santander Shares (Brazil)	13,149	19,719
Global	Santander Spain Shares and Options	4,638	2,708

b) Share-ReferencedVariable Compensation

The long-term incentive plan (deferral) sets forth the requirements for payment of future deferred installments of variable remuneration, considering the long-term sustainable financial bases, including the possibility of applying reductions or cancellations due to the risks assumed and fluctuations in 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 accounted for under Personnel Expenses, as follows:

Program	Participant	Liquidity Type	01/01 to 09/30/2023	01/01 to 09/30/2022
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)	114,449	26,290
Unidentified Collective	Other employees with variable remuneration above a minimum expected value	50% in cash indexed to 100% of CDI and 50% in shares (Units SANB11)	151,167	63,406

Operating segments

Under IFRS 8, an operating segment is a component of an entity:

(a) That engages in activities from which it may earn revenues and incur expenses (including revenues and expenses relating to transactions with other components of the same entity);

(b) whose operating results are regularly reviewed by the entity primarily responsible for operating decisions relating to the allocation of resources to the segment and the assessment of its performance; and

Based on these guidelines, the Bank identified the following reportable operating segments:

• Commercial Bank

• Global Wholesale Bank

The Bank has two segments, the commercial segment, which includes individuals and companies (except for global corporate clients, which are dealt with in the Global Wholesale Banking segment) and the Global Wholesale Banking segment, which includes Investment Banking and Markets, including treasury departments and equity businesses.

The Bank operates in Brazil and abroad, through the Cayman and Luxembourg branches, with Brazilian customers and, therefore, does not present geographic segmentation.

17. Fair value

of financial assets and liabilities

Under IFRS 13, the fair value measurement uses a fair value hierarchy that reflects the model used in the measurement process which should be in accordance with the following hierarchical levels:

Level1: Determined on the basis of public (unadjusted) quoted prices in highly active markets for identical assets and liabilities, these include public debt securities, stocks, derivatives listed.

Level2: They are those derived from inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (as prices) or indirectly (derived from prices).

Level3: They are those derived from valuation techniques that include inputs for the asset or liability that are not based on observable market data (unobservable inputs).

Financialassets and liabilities at fair value on through income statement or othercomprehensive income

Level1: The securities with high liquidity and quoted prices in the active market are classified as level 1. At this level there were classified most of the Brazilian Government Securities (mainly LTN, LFT, NTN-B, NTN-C and NTN-F), shares in stock exchange and other securities traded in the active market.

Level2: 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 derived 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, particularly interest rates. These bonds and securities are classified at level 2 of the fair value hierarchy and are composed mainly of Government Securities (Repo, Cancelable LCI and NTN) in a less liquid market than those classified in the level.

Level3: When there is information that is not based on observable market data, Banco Santander uses internally developed models, from curves generated according to the internal model. Level 3 comprises mainly unlisted shares.

Derivatives

Level1: Derivatives traded on stock exchanges are classified in Level 1 of the hierarchy.

Level2: For derivatives traded over the counter, the valuation (primarily swaps and options) usually uses observable market data, such as: exchange rates, interest rates, volatility, correlation between indexes and market liquidity.

When pricing the financial instruments aforementioned, it is used the Black-Scholes Model (exchange rate options, interest rate options; caps and floors) and the present value method (discount of future values by market curves).

Level3: Derivatives not traded in the stock exchange and that do not have observable data in an active market were classified as Level 3, and these are composed by exotic derivatives.

The following table shows a summary of the fair values of financial assets and liabilities for the period ended September 31, 2023, and december 31, 2022, classified based on several measurement methods adopted by the Bank to determine their fair value:

Fairvalue 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 credit risks for a specific financial asset.

When said 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 base interest rate or other rates observed on market. 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 benchmark that the market may require for the financial asset.

Financialassets and liabilities not measured at fair value

The Bank's financial assets are measured at fair value in the consolidated balance sheet, except for financial assets measured at amortized cost.

In the same sense, the Bank's financial liabilities, except for financial liabilities held for trading and those measured at fair value

- are stated at amortized cost in the consolidated balance sheet.

The methods and assumptions used to estimate fair value are defined below:

Loansand amounts due from credit institutions and from clients– Fair value is estimated by groups of similar credits. 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 loan portfolio is estimated based on contractual rates, and then spreads based on new loans are factored into the risk-free yield curve in order to calculate the fair value of the credit portfolio. In terms of behavioral hypotheses, it is important to underline that the prepayment rate is applied to the credit portfolio.

Depositsfrom Bacen and credit institutions and Client deposits– The fair value of deposits was calculated by discounting the difference between the cash flows under the contractual conditions and the rates currently practiced in the market for instruments whose maturities are similar. The fair value of time deposits with variable rate was considered as close to its book value.

Debtand Subordinated Securities – The fair values of these items were estimated by calculating the cash flow discounted using the interest rates offered in the market for obligations with similar terms and maturities.

DebtInstruments Eligible to 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 fair value.

Otherfinancial liabilities - according to the explanatory note, substantially include amounts to be transferred arising from the operations of credit cards, transactions pending settlement and dividends and interest on shareholders' equity payable, the carrying amount of which is similar at its fair value.

The valuation 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 cost amortized, presented exclusively for disclosure purposes and concluded that they best fit as level 3 in view of the data market observables.

18. Other

disclosures

a) **** Trading and hedging derivatives

The main risk factors of the derivative instruments assumed are related to exchange rates, interest rates and variable income. In managing this and other risk factors for market, practices are used that include measuring and monitoring the use of limits previously defined in internal committees, the value at risk of the portfolios, the sensitivities fluctuations in interest rates, exchange rate exposure, liquidity gaps, among other practices that allow for the control and monitoring of risks, which may affect the Bank's positions Santander 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 ratio even in highly volatile situations.

The fair value of derivative financial instruments is determined through quoted market prices. The fair value of swaps is determined using flow modeling techniques discounted cash, reflecting appropriate risk factors. The fair value of forward and futures contracts is also determined based on quoted market prices for derivatives traded on exchanges 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 are not directly priced disclosed by exchanges, the fair price is obtained through pricing models that use market information, inferred from published prices of more liquid assets. Of these prices are extracted from interest curves and market volatilities that 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 result. To eliminate these asymmetries or reduce volatility, the Bank uses derivative financial instrument contracts (Swap and Futures) that are assigned to Accounting Hedge structures of fair value or cash flow.

IV.I)Fair Value Hedge

The Bank's fair value hedge strategy aims to protect the fair value of assets and liabilities arising from fluctuations in the reference interest rate (CDI, SELIC, SOFR); in currency fluctuations (Exchange rate risk) and/or price index fluctuations (IPCA, etc). The Bank monitors each hedge structure, assessing 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 variation in the value of the hedging instrument is temporarily recognized in equity under the caption "Other comprehensive income - cash flow hedges" (Note 25) until the forecast transactions occur, when then this portion is recognized in the consolidated statements of income, except, if the anticipated transactions result in the recognition of non-financial assets or liabilities, this portion will be included in the cost of the financial asset or liability.

Performance Commentary

Dear Stockholders:

We present the Performance Commentary to the Condensed Individual and Consolidated Financial Statements of Banco Santander (Brasil) S.A. (Banco Santander or Banco) for the period ended September 30, 2023, prepared in accordance with the International Financial Reporting Standards (IFRS) standards issued by the Accountant Standards Board (IASB), and the interpretations issued by the IFRS Interpretations Committee (name of the International Financial Reporting Interpretations Committee – IFRIC).

1. Macroeconomic Environment

At the end of the third quarter of 2023, Banco Santander observed the median of economic agents' projections regarding the performance of the Brazilian economy indicating Brazilian GDP growth of 2.9% in 2023 - the same pace of expansion observed in the previous year. The projection for 2023 is higher than that observed at the end of the second quarter of 2023 (2.2%) and, in the Bank's assessment, the upward revision was caused by a new positive surprise recorded in 2Q23 resulting from the remaining effects of the sector's strong performance agriculture in 1Q23 and the expansion of aggregate demand in the wake of high resilience seen in the labor market. However, despite the positive surprise in the first half of the year, the dynamics of activities more linked to the economic cycle reinforced the perception that the economy is in a slowdown pace in the wake of the contractionary effects arising from the cycle of rising interest rates that began. in 2021 and ending in August 2022. In addition to the contribution of the agricultural sector and the maintenance of favorable conditions in the labor market, it seems to us that the prospect of GDP variation remaining in positive territory results from the maintenance of the fiscal stimuli that were implemented during throughout 2022 and which were partially extended at the beginning of 2023. The recently released economic activity data came in line with our estimate of GDP slowdown in the following quarters, but the more promising start of the year led us to revise our projection of expansion of Brazilian GDP from 1.9% to 2.5% in 2023.

In the third quarter of 2023, the Bank witnessed the interannual variation of the IPCA rise to 5.1% compared to the level of 3.2% observed at the end of June 2023. The recent increase in the interannual variation of the IPCA is compatible with the reversal (albeit partial) of temporary tax cuts introduced in the second half of 2022, which helped to reduce inflation year-on-year during the first half of 2023. However, despite this reversal of trajectory, we have seen marginal improvement in price dynamics, mainly with regard to services. Therefore, we revised our projection for the IPCA variation in 2023 from 5.2% to 4.7% between the end of the second quarter and the end of the third quarter. Although the result is higher than both the target and the ceiling of the tolerance interval stipulated in the monetary regime, we assess that the change in price dynamics ended up being the main factor for the Central Bank of Brazil to initiate a process of monetary easing and reduced the basic interest rate by 1.0 percentage point at the Copom meetings in the third quarter, bringing the Selic to 12.75% p.a. However, the Bank understands that the inflationary environment and the balance of risks still inspire caution on the part of the Brazilian monetary authority and that this approach increases the chance that inflation will converge to the targets established within the relevant time horizon for monetary policy. Mainly after the approval of the new fiscal framework, with the government signaling that it will increase the amount of public spending from this year onwards, which could make the disinflation process slower. In this sense, the Bank projects that the Selic rate will reach 11.75% p.a. at the end of 2023 and 9.50% p.a. at the end of 2024.

Regarding the behavior of the exchange rate, Banco Santander saw the exchange rate of the Brazilian currency against the US dollar fluctuate between R$4.70/US$ and R$5,05% in the third quarter and end the period quoted at R$5,01/US$. In other words, a level higher than the price of R$4.79/US$ verified at the end of 2Q23. In the Bank's view, the devaluation of the real resulted from the difficulty in approving measures complementary to the new fiscal framework, something that revived uncertainty regarding the trajectory of public debt in the medium term. In addition to domestic factors, we also had the consolidation of the perception that global monetary conditions will remain in a restrictive field for longer than previously imagined. The central banks of advanced economies (for example, the Federal Reserve in the USA and the Bank of England) have signaled that they will maintain their interest rates at a high level for a sufficiently long period to guarantee the convergence of inflation to lower levels. This background also affected the behavior of the real in the period. The volatility demonstrated by the real's trajectory is in line with our prediction that the exchange rate will have limited space to register significant appreciation in the coming years. In fact, we project that the exchange rate will reach R$5.10/US$ by the end of 2023 and R$5.25/US$ by the end of 2025.

The performances mentioned above took place in the midst of an international environment that the Bank considered unfavorable and which highlighted the following themes: 1) maintenance of inflationary pressures around the globe; 2) signaling of more extensive adjustment in monetary policy in advanced economies and; 3) frustration regarding the pace of recovery of the Chinese economy. In the domestic environment, Santander understands that the main themes were the following: 1) difficulty in advancing complementary proposals to support the new fiscal framework recently approved; 2) positive surprise with economic growth in 2Q23 derived from resilience in the job market and; 3) marginal improvement in inflationary dynamics, mainly in services, reinforcing the continuity of the cycle of interest cuts throughout 4Q23.

2.3) Stockholders’ Equity

As of September 30, 2023, Banco Santander's consolidated shareholders' equity increased by 2.8% compared to December 31, 2022.

The variation in Shareholders' Equity between September 30, 2023 and December 31, 2022 was mainly due to the negative equity valuation adjustment in employee benefit plans in the amount of R$432 million and net of tax effects on net income for the period in the amount of R$7,404 million and the positive equity valuation of financial assets measured at fair value through Cash Flow and Investment Gains and Losses in the amount of R$485 million and financial assets measured at fair value through other comprehensive income of R$24 million.

For additional information, see explanatory note to financial statements No. 11.

2.4) Basel Index

Bacen determines that financial institutions maintain a Reference Equity (PR), PR Tier I and Core 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.

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%. In continuity 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:

Basel Index%	Set/23	Dec/22
Reference Equity Level I	79,340.7	75,943.7
Principal Capital	72,775.7	69,229.0
Supplementary Capital	6,565.0	6,714.7
Reference Equity Level II	13,679.9	13,109.8
Regulatory Capital (Tier I and II)	93,020.6	89,053.5
Credit Risk	559,687.3	559,230.6
Market Risk	30,152.9	19,332.1
Operational Risk	60,492.1	60,073.2
Total RWA	650,332.3	638,635.9
Basel Level I Ratio	12.20	11.89
Basel Principal Capital	11.19	10.84
Basel Regulatory Capital	14.30	13.94

(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) Includes portions for market risk exposures subject to variations in interest rates (RWAjur1), foreign currency coupons (RWAjur2), price indices (RWAjur3), and interest rate coupons (RWAjur4), price of commodity goods (RWAcom), the price of shares classified in the trading portfolio (RWAacs), installments for exposure of gold, foreign currency and operations subject to exchange rate variation (RWAcam), and adjustment for derivatives arising from changes in the credit quality of the counterparty (RWAcva).

(3) Risk Weighted Assets or risk-weighted asset

2.5) Main Subsidiaries

The table below shows the balances of total assets, shareholders' equity, net income and loan portfolio prepared in accordance with accounting practices adopted in Brazil applicable to entities authorized to operate by Bacen, for the period ended September 30, 2023, of Banco Santander's main subsidiaries:

Esfera Fidelidade S.A.	3,020.0	132.4	594.4	-	100.00%

The financial statements of the Subsidiaries above were prepared in accordance with the accounting practices adopted in Brazil, established by the Brazilian Corporate Law, in conjunction with the CMN, Bacen rules and model of the document provided for in the Accounting Plan of Cosif Institutions, of CVM, in which they do not conflict with the rules issued by Bacen, without the elimination of transactions with related companies.

3. Corporate Restructuring

During the quarter ended September 30, 2023 and the year ended December 31, 2022, several corporate movements were implemented in order to reorganize the operations and activities of entities in accordance with Banco Santander's business plan.

For additional information, see explanatory note to financial statements No. 2.

4. Strategy and Rating Agencies

For information regarding the Bank's strategy and rating at rating agencies, see the Results Report available at www.santander.com.br/ri.

5. Corporate Governance

Banco Santander Brasil's governance structure is made up of the Executive Board and its Executive Committee, made up of the Chief Executive Officers, Senior Executive Vice-Presidents and Executive Vice-Presidents, and the Board of Directors and its Advisory Committees, namely: Audit, Risks and Compliance, Sustainability, Compensation and Nomination and Governance.

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

6. Risk Management

On february 23, 2017, Bacen published CMN Resolution No. 4,557, which provides for the risk and capital management structure (GIRC) coming into force in the same year. The resolution highlights the need to implement an integrated risk and capital management structure, definition of an integrated stress test program and Risk Appetite Statement (RAS - Risk Appetite Statement), creation of a Risk Committee, definition of a disclosure policy of published information, appointment of director for risk management, director of capital and director responsible for the information disclosure policy.

Banco Santander takes the necessary actions on a continuous and progressive basis, with a view to complying with the resolution. No relevant impacts arising from this standard were identified.

For more information, see explanatory note nº 18 of this publication.

CapitalManagement

Banco Santander's capital management structure relies on robust governance, which supports the processes related to this topic and establishes the attributions of each of the teams involved. In addition, there is a clear definition of the guidelines that must be adopted for effective capital management. Further details can be found in the Capital and Risk Management Structure, available on the Investor Relations website.

InternalAudit

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

Internal Audit is a permanent function, independent from 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, risk management processes and systems (currently or emerging) and government, thus helping to protect the organization's value, solvency and reputation. Internal Audit has a quality certificate issued by the Institute of Internal Auditors (IIA).

In order to fulfill its functions and cover risks inherent to Banco Santander's activity, the 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 the 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 2023.

7. People

In our company we continue to take care of our people. After all, they are the ones who think, design, develop, interact and build what we want to be. This is the reason we invest in each of the 55,885 employees here in Brazil.

For the development of our people, the Corporate University – Academia Santander, works towards a strong, transversal culture, allowing everyone, online and in person, to improve what they already know and explore new possibilities. From mandatory certifications for certain functions to Digital Leadership courses, the most important thing is to leave your comfort zone and invest in yourself by expanding your knowledge and repertoire.

Our company supports leaders and managers so that they are close and available. This action is based on three pillars: Feedback, Open Chat and Personalized Recognition, ensuring alignment between everyone through recurring and frank conversations, career guidance and special moments to reward team growth.

Santander values a diverse environment, where each skill and difference is valued. An example is the Affinity Group, created to promote diversity and inclusion based on the 5 pillars: Female Leadership; Racial Equity; Disabled people; Diversity of Backgrounds, Experiences and Generations and the LGBTQIA+ pillar.

The professional and personal growth of our employees is also one of the pillars of our culture, which is why, in July we launched the new Santander Career Hub where employees can learn about our career possibilities and the necessary skills.

In the Customer sphere, we remain focused on offering the best products and services, in a Simple, Personal and Fair way.

In September we had Santander Week, which took place in all Santander units around the world. This year, our activities were focused on our TEAMS corporate behaviors (Think Customer – I think about the Customer, Embrace Change – I Drive Change, Act Now – I act quickly, Move Together – Teamwork and Speak Up – I speak openly). There were several activities and information with our employees and customers in mind. We were also able to emphasize Amigo de Valor, which supports public policies aimed at guaranteeing the rights of children and adolescents and allows the allocation of part of the income tax due directly to the Children and Adolescents' Rights Funds, in addition to volunteering actions of our employees throughout Brazil.

8. Sustainability

Our purpose is to contribute to the progress of people and businesses. At the same time, we want to support the construction of a fairer and more sustainable Brazil. We have a clear strategy for our environmental aspirations (to be a reference in sustainable business), social aspirations (working so that everyone has opportunities) and governance aspirations (having the best ESG management practices).

Environmental

We remain committed to supporting our customers in solutions for a low-carbon economy. In the year to date, we have enabled R$16,4 billion in sustainable businesses, including green bonds, Project Finance and products aimed at agribusiness and microcredit, for example.

Some highlights:

· 108 transactions approved, totaling R$6 billion in assets and R$7,1 billion in capital market operations.

· 32 training sessions carried out with commercial teams, with more than 1,000 people impacted.

· More than 1 million active customers on Prospera, with growth of 28% (YoY). Already in the portfolio, we reached R$3 billion, growth of 22% (YoY).

· Structuring the Sovereign Sustainable Finance Framework and mandated the first issuance of Green Treasury Bonds and participation in the issuance of R$7 billion green debentures by Eletrobras.

· Membership of the Alliance for Sustainable Mobility to provide financial solutions that enhance the infrastructure necessary for electromobility and reduce barriers to purchasing an electric vehicle. Our first operation involved 300 BYD electric vehicles financed by Dahruj, a car rental company, to be used by company 99 taxi drivers.

· Launch of the Sustainable Mobility & Innovation Award, together with Financeira, which aims to recognize our store owners and partner dealerships who work with ESG initiatives.

· We acquired FIT Economia de Energia, a Hy Brazil Energia platform that connects clean energy generators to low voltage consumers (individuals, small and medium-sized companies). The operation will allow the Bank to offer renewable energy to individuals and small and medium-sized companies with a reduction in electricity bills.

Social

Between July and September 2023, we promoted important actions aimed at the communities where we operate.

In August 2023 we promoted the 5th edition of Preparadão, and the first edition in the format of an employability fair aimed at young people aged up to 24 with a family income of up to four minimum wages, looking for their first job. The event, held by Universia, a Santander Group company, which supports young people through education and access to the job market, took place at Santander Geração Digital, Santander Brasil's technology hub, in São Paulo, and was attended by more than 10 thousand registered. There were two days of debates and reflections on the future of work, training for the first job, diversity and technology. In parallel, the meeting also promoted interactions with more than 20 participating companies, including a real-time employability shark tank, with the main objective of promoting diversity, equity and inclusion.

In September 2023 we launched the 21st edition of Amigo de Valor, a program that works to guarantee the rights of children and adolescents who are in vulnerable situations. Santander customers can make donations or allocate part of the income tax due (individuals up to 6% and companies up to 1%). The campaign, which ends on November 24, has already raised more than R$19 million, which will impact around 10 thousand children and adolescents in municipalities with low or medium HDI (Human Development Index). To learn more and participate, visit https://www.santander.com.br/amigodevalor/adesao/.

We also promote Santander Week, which celebrates the corporate culture of Santander Brasil and its affiliates. Among the actions carried out, the mobilization of the Amigo de Valor program stands out, as well as activities and lectures focused on volunteering, mentoring for productive inclusion and financial education with social organizations and public school students.

Governance

With the entry of a new woman on the Board of Directors, the participation of women and independent members on the Board of Directors increased, now representing 36% and 54%, respectively.

In July 2023, we published our first Social, Environmental and Climate Risks and Opportunities Report (GRSAC), which describes Santander Brasil's social, environmental and climate risks and opportunities management structure for the year 2022, in compliance with BCB Resolution no. 139 of 9/15/2021.

In August 2023 we became part of IDIVERSA B3, the first Latin American index on the Brazilian stock exchange, focusing on race and gender, and which recognizes listed companies with outstanding diversity. The initial portfolio is made up of 79 assets from 75 companies. https://www.b3.com.br/pt_br/noticias/b3-lanca-primeiro-indice-de-diversidade-com-foco-em-genero-e-raca.htm

In August 2023, Grupo Santander won the Euromoney Award in the SMEs category, with emphasis on financial inclusion and emerging markets. Santander Brasil has direct participation due to financial inclusion and banking initiatives carried out in the country. https://www.euromoney.com/santander.

9. Independent Audit

Banco Santander's operating policy, including its subsidiaries, 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 auditor's independence. This rationale provides for the following: (i) the auditor must not audit his own work, (ii) the auditor must not exercise managerial functions at his client, (iii) the auditor must not promote the interests of his client, and (iv) the 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 quarter ended September 30, 2023, no services were provided by PricewaterhouseCoopers unrelated to independent audits of the Financial Statements of Banco Santander and controlled companies greater than 5% of total fees for independent audit services.

Furthermore, the Bank confirms that PricewaterhouseCoopers has procedures, policies and controls in place to ensure its independence, which include an assessment of the work performed, covering any service other than an independent audit of the Financial Statements of Banco Santander and its subsidiaries. Said assessment is based on the 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 quarter ended September 30, 2023, did not affect the independence and objectivity in conducting the external audit examinations carried out at Banco Santander and other entities of the Group, since the principles indicated above were observed.
