Additionally, it has an Audit Committee which, among its responsibilities and competencies, in addition to providing opinions and recommendations on the audit service provider, also evaluates the effectiveness of independent and internal audits, including verifying compliance with legal and regulatory provisions applicable to Inter, as well as internal policies and codes.
Furthermore, Inter&Co, Inc. confirms that KPMG Auditores Independentes Ltda. has procedures, policies, and controls in place to ensure its independence, which include an assessment of the work performed, encompassing any service that is not an independent audit of the consolidated financial statements. This assessment is based on applicable regulations and accepted principles that preserve auditor independence. The acceptance and performance of professional services unrelated to the audit of the financial statements by the independent auditors during the period ended June 30, 2026, did not affect the independence and objectivity in the conduct of the audit examinations performed at Inter&Co, Inc. Information regarding the independent auditors' fees is made available annually in the reference form.

b.Functional and presentation currency
The consolidated condensed interim financial information is presented in Brazilian reais (R$). The functional currency of the Group companies is shown in explanatory note 4a, reflecting the currency in which the prices of goods and services are determined and generally settled. All amounts have been rounded to the nearest thousand, unless otherwise indicated.
c.Use of estimates and judgments
In preparing the consolidated condensed interim financial information, Management used judgment, estimates and assumptions that affect the application of the Group's accounting policies and the reported amounts of assets, liabilities, revenues and expenses. Actual results may differ from these estimates. Estimates and assumptions are reviewed continuously and the impacts of changes in estimates are recognized prospectively. The main significant judgments made by management in applying the Group's accounting policies and the sources of uncertainty in the estimates are described below:
Judgments
Information about judgments made in applying accounting policies that have the most significant effects on the amounts recognized in the financial statements is included in the following notes:
•Basis for consolidation (see note 4a): whether Inter&Co has actual control over an investment;
•Classification of financial assets (see notes 6 and 7): whether such assets meet the criteria for payment of principal and interest only (SPPJ test) and their respective classification (amortized cost, fair value through comprehensive income, or fair value through profit or loss); and
•Equity method: if Inter&Co has significant influence over an investee.
Estimates
Estimates carry a significant risk and could materially affect the values of assets and liabilities in future periods, and actual results may differ from those based on such estimates. The main items susceptible to impacts from estimates are disclosed below and are related to the following explanatory notes:
•Classification of financial assets (see notes 6 and 7): assessment of the business model in which the assets are held and assessment of whether the contractual terms of the financial asset refer only to principal and interest payments (SPPJ test);
•Business combination (see note 4b): determination of the fair values of assets acquired and liabilities assumed in business combinations;
•Impairment test of intangible assets and goodwill (see note 14): for the purposes of recoverability testing, each investee entity was considered a cash-generating unit (“CGU”);
•Deferred tax asset (see note 32): the expectation of realizing the deferred tax asset is based on projections of future taxable profits and other technical studies;
•Provision for expected credit losses (see notes 12d and 21): the measurement of provisions for expected credit losses on financial assets measured at amortized cost, credit commitments, receivables and financial guarantees provided, requires the use of complex quantitative models and assumptions about future macroeconomic conditions and credit behavior. Several significant judgments are also necessary to apply the accounting requirements for measuring expected credit loss, such as: determining the criteria for assessing a significant increase in credit risk; selecting appropriate quantitative models and assumptions to measure expected credit loss; and establishing different prospective scenarios and their weighting, among others; and.
•Provisions (see note 21): recognition and measurement of provisions, including provisions for legal proceedings. The main assumptions considered relate to the probability and magnitude of resource outflows.

New or revised accounting pronouncements adopted in 2026
The following standards, new or revised, have been issued by the IASB and adopted by the Group for the periods covered by this consolidated condensed interim financial information.
•Changes to IFRS 9 – Financial Instruments and IFRS 7 – Financial Instruments Disclosures: issued in May 2024, the changes and clarifications relate to the write-off of financial liabilities through electronic systems, assessment of the contractual characteristics of cash flow in the classification (SPPI Test), such as: financial assets linked to ESG (Environmental, Social and Governance) among other financial instruments. In addition, further disclosures were included regarding equity instruments designated at fair value through other comprehensive income and financial instruments linked to contingent events. Management did not identify any relevant impacts on its consolidated condensed interim financial information, considering the instruments currently recognized by the Group.
•Changes to IFRS 7 – Derecognition Gains and Losses: the changes aim to: disclose deferred differences between fair value and transaction price, and change the classification and measurement of financial instruments, effective from January 1, 2026. Management has not identified any significant impacts on its consolidated condensed interim financial information, considering the instruments currently recognized by the Group.
•Changes to IAS 7 – Statement of Cash Flows: the main change refers to the clarification of paragraph 37, establishing that, when accounting for an investment in an associate, a joint venture, or a subsidiary using the equity method or the cost method, the investor restricts its presentation in the statement of cash flows to cash flows between itself and the investee, for example, dividends and advances. Effective from January 1, 2026. Management has not identified any significant impacts of these changes on its consolidated condensed interim financial information.
•Changes to IFRS 10 – Consolidated Financial Statements: this aims to define control and provide guidance for the transition after the application of the new concept, as well as clarifications regarding the sale or contribution of assets between related entities, effective from January 1, 2026.

The standard also provides guidance on the disclosure of performance indicators defined by Management and sets specific requirements for companies in the banking and insurance sectors. IFRS 18 will come into effect on January 1, 2027, and Management is evaluating the effects of adopting this standard on the Group's consolidated condensed interim financial information.
•IFRS 19 – Subsidiaries without Public Responsibility - Disclosures: issued in May 2024, the standard defines that a subsidiary without public liability may provide reduced disclosures when applying IFRS accounting standards to its financial statements. The standard is optional for eligible subsidiaries and establishes the disclosure requirements for subsidiaries that choose to apply it. IFRS 19 will come into effect on January 1, 2027, and Management is evaluating the effects of adopting this standard.

6.Financial risk management
The Group's risk management encompasses credit, market, liquidity, and operational risks. Risk management activities are carried out by independent and specialized structures, according to pre-defined policies and strategies, with the objective of identifying, measuring, monitoring, mitigating, and controlling exposure to financial and non-financial risks to which Inter is subject.
The model adopted by the Group is organized through governance bodies and committees supported by appropriate methodologies, models, and tools, seeking to ensure, among other things:
•Segregation of duties and independence between business and control areas;
•A dedicated risk management unit responsible for monitoring and reporting to the relevant authorities;
•Formalized management process, with defined responsibilities and information flows;
•Clear rules, a structure of competencies and levels of authority that are compatible with the complexity of the operations;
•Defined limits and margins, aligned with risk appetite and strategic guidelines; and
•Adopting best market practices, seeking continuous improvement in management effectiveness.
a.Credit risk
Credit risk is defined as the possibility of losses arising from the borrower's or counterparty's failure to meet the financial obligations assumed under the agreed terms, as well as the devaluation of credit contracts resulting from an increased risk of borrower default, among other factors.
Financial instruments exposed to credit risk are subject to a rigorous pre-contractual evaluation process, maintained continuously throughout the term of the respective operations. Credit analyses consider the economic and financial capacity of the borrower or counterparty, credit behavior, including payment history, credit reputation in the market, as well as the terms and conditions of each operation, encompassing terms, rates, and guarantees.
The table belows presents the maximum credit risk exposure of financial assets and liabilities:

|  |  |  | 06/30/2026 |  | 12/31/2025
Financial Assets |  | Note |  | Gross value |  | Expected loss |  | Gross value |  | Expected loss

(a) Refers to an advance payment on a foreign exchange contract.
Inter Group's main risk exposure is related to loan and customer advance portfolio, as presented in explanatory note no.12, and is mainly represented by operations of:
•Credit card: credit transactions related to credit card limits, mostly without attached guarantees;
•Business loans: working capital operations, receivables, discounts and loans in general, with or without collateral;

|  |  |  | 18

| Notes to the interim condensed consolidated financial statement As of June 30,2026

•Real estate loans: loan and financing operations secured by real estate, with collateral linked to the underlying assets;
•Personal loans: loan and payroll deduction card transactions with and without collateral; and
•Agribusiness loans: financing operations for the costs of rural production, investment, marketing and/or industrialization granted to rural producers, with or without collateral.
Mitigation of Exposure
To maintain exposures within the risk levels established by senior management, Inter&Co adopts measures to mitigate credit risk. Credit risk exposure is mitigated through the structuring of guarantees, adapting the level of risk to be incurred to the characteristics of the guarantees provided at the time of granting. Risk indicators are continuously monitored, and proposals for alternative mitigation methods are evaluated whenever the credit risk exposure behavior of any unit, region, product, or segment so requires. Additionally, credit risk mitigation occurs through product repositioning and adjustments to operational processes or transaction approval levels.
Credit standards guide operational units and encompass, among other aspects, the classification, requirement, selection, evaluation, formalization, control, and reinforcement of guarantees, ensuring the adequacy and sufficiency of mitigating instruments throughout the credit cycle.
In 2026, there will be no material changes in the nature of credit risk exposures, how they originate, or the Group's objectives, policies, and processes for managing them, although Inter&Co will continue to continuously improve its internal risk management processes.

Total |  | 51,926,990 |  |  | 48,251,180 |

Measurement
Measurement of credit risk at the Group is carried out considering the following:
•At the time of granting credit, an assessment of the client's financial situation is carried out through the application of qualitative and quantitative methods, in order to support the adequacy of the risk exposure;
•The assessment is performed at the counterparty level and considers information on collateral, where applicable. Credit risk exposure is measured under extreme scenarios through stress tests and analysis of macroeconomic conditions—such as interest rates, unemployment rates, inflation indices, and economic activity; and
•The models used to determine the internal rating of customers and loans are periodically reviewed to ensure they reflect the expected losses, as detailed in explanatory note 12. The estimate of expected losses on financial assets is divided into three categories (stages):
•Stage 1: financial assets that have not shown a significant increase in credit risk;
•Stage 2: financial assets that have shown a significant increase in credit risk; and
•Stage 3: financial assets that have shown indications that they will not be fully honored under the originally agreed terms, or that are involved in bankruptcy proceedings, judicial reorganization, debt restructuring, or that require the enforcement of guarantees. Therefore, they are characterized as problematic assets.
•Payment delays in portfolios are monitored to identify trends or changes in credit behavior and allow for the adoption of mitigating measures when necessary;
•Expected credit loss reflects the risk level of loans and allows for monitoring and controlling the portfolio's exposure level and the adoption of risk mitigation measures;
•Expected credit loss is a forecast of the risk levels of the loan portfolio. Its calculation is based on the historical payment behavior and the portfolio's distribution by product and risk level. This is a fundamental contribution to the process of setting prices for loans and advances to customers.
•In addition to monitoring and measuring indicators under normal conditions, simulations of changes in the business environment and economic scenario are also carried out. This is done with the aim of predicting the impact of these changes on risk exposure levels, provisions and portfolio balance, as well as to support the process of reviewing exposure limits and credit risk policy; and
•Expected losses are calculated by multiplying the credit risk parameters, as follows:
▪Probability of Default (PD): this refers to the probability of the client defaulting on their agreed obligations, according to internal evaluation models based on statistical methodologies. These models consider client behavior, internal ratings, business segments, product characteristics and warranties, as well as financial information and qualitative analyses from experts;

|  |  |  | 20

| Notes to the interim condensed consolidated financial statement As of June 30,2026

▪Loss Given Default (LGD): this refers to the percentage of loss relative to exposure in cases of default events, considering recovery efforts. Internal evaluation models are based on statistical methodologies that take into account the characteristics of the operation, such as product and warranty; and
▪Exposure at Default (EAD): this refers to the book value of the exposure at the time the expected loss is estimated. In the case of credit commitments or receivables to be released, the EAD will include the expected value of converting these amounts into exposure on the part of the customers.
b.Description of guarantees
Potential losses related to financial instruments are mitigated by the use of various types of real guarantees, formalized through legal instruments. The evaluation/re-evaluation of the effectiveness of the guarantees is carried out at least once every twelve months, considering the characteristics of the asset given as collateral, its market value, and the legal security of the contracts.
The main forms of collateral are: term deposits; financial investments; securities; residential and commercial real estate; vehicles; promissory notes and credit card invoices. Among the guarantees and sureties, bank guarantees stand out.
Payroll loans, substantially represented by payroll-deducted credit cards and personal loans, are deducted directly from borrowers' pensions, income, or salaries and settled directly by the entity responsible for making these payments (a private company or government agency). Credit cards generally do not have collateral.
Guarantees of real estate loans and financing
The guarantees for a Real Estate Loan Portfolio are substantially constituted by the financed property. The following table demonstrates the value of loans secured by real estate, segregated by Loan to Value (LTV). LTV is the ratio between the value of a loan and the value of the financed asset. When it is higher, it may signal a greater risk for the lender, since it indicates a lower participation of the borrower's own capital in the transaction.

| 06/30/2026 |  | 12/31/2025
Less than or equal to 30% | 2,752,728 |  |  | 2,565,053 |
Greater than 30% and less than or equal to 50% | 4,872,550 |  |  | 4,432,991 |
Greater than 50% and less than or equal to 70% | 6,622,315 |  |  | 6,646,170 |
Greater than 70% and less than or equal to 90% | 3,874,372 |  |  | 2,415,905 |
Greater than 90% | 127,903 |  |  | 134,603 |
Total | 18,249,868 |  |  | 16,194,722 |

c.Liquidity risk
Liquidity risk represents the possibility that the Group may not be able to efficiently meet its financial obligations, whether expected or unexpected, including obligations arising from guarantees granted and extraordinary redemptions by clients. This risk also covers scenarios in which Inter&Co may face difficulties in liquidating assets at market prices, either due to the significant volume of the operation in relation to usual activity, or due to market disruptions or dysfunctions.
Liquidity risk is managed institutionally through a governance structure with responsibilities clearly distributed among the Board of Directors, the Assets and Liabilities Committee (ALCO), the Risk Committee, and the Risk Management Office (CRO). Specifically, the Risk Management Office is responsible for the continuous monitoring and tracking of liquidity risk exposure.

| Notes to the interim condensed consolidated financial statement As of June 30,2026

The risk management structure operates independently and proactively, aiming to continuously monitor liquidity indicators and prevent any exceeding of established limits. Management comprehensively covers Inter&Co's cash inflows and outflows, allowing for the timely implementation of mitigation actions when necessary.
Liquidity risk monitoring is performed daily, and its follow-up is conducted periodically by the Assets and Liabilities Committee (ALCO), which systematically evaluates the available information, including:
•Analysis of the mismatch between assets and liabilities, net inflows, and maturity forecasts;
•Monitoring of liquidity limits and ratios;
•Concentration of investors and exposure to liquidity risk of the Group;
•Stress tests and liquidity contingency plans; and
•Periodic reports on the positions of Inter and its subsidiaries.
The structure considers internal and external factors that impact the Group's liquidity, carrying out detailed daily monitoring of incoming and outgoing loan and customer advance transactions, Certificates of Deposit (CDB), Savings Deposits, Agribusiness Credit Notes (LCA), Real Estate Credit Notes (LCI), Guaranteed Real Estate Notes (LIG), Financial Notes (LF) and Demand Deposits.
The information presented in note 6.d constitutes a relevant component of liquidity risk monitoring and is observed and used by the Group in this context.
Up to the base date of June 30, 2026, there have been no material changes in the nature of liquidity risk exposures, monitoring methodologies, internal policies, and the Group's processes for managing them. The Group, however, continues to improve its internal risk management processes.

f.Market risk
Market risk is defined as the possibility of losses resulting from fluctuations in the market values of positions held by the Institution and its subsidiaries, including the risks of operations subject to exchange rate variations, interest rates, stock prices, and commodity prices.
Market risk management aims primarily to support business areas by establishing processes and implementing the necessary tools for assessing and controlling related risks. This structure enables the measurement and monitoring of risk levels according to guidelines established by senior management. Monitoring is carried out daily, with periodic follow-up conducted by the Assets and Liabilities Committee (ALCO). Market risk controls allow for the analytical evaluation of information and are in a constant process of improvement.
Measurement
Within the risk management process, Inter&Co classifies its operations, including derivative financial instruments, as follows:
•Trading book: This includes all transactions intended for trading before their contractual expiration or intended to hedge the trading portfolio and that are not subject to limitations on their negotiability.
•Banking book: This includes transactions not classified in the trading portfolio.
Aligned with best market practices, the Group manages its risks dynamically, seeking to identify, measure, evaluate, monitor, report, control, and mitigate market risk exposures from its own positions. One of the main evaluation tools is the value at risk (VaR) model, calculated using a parametric methodology, with a 99% confidence level and a 21-business-day time horizon.

(a) Price index coupon is composed of the risk factors IPCA (consumer price index calculated by IBGE - Brazilian Institute of Geography and Statistics) and IGPM (General Price Index - Market), calculated by Fundação Getulio Vargas (FGV); and
(b) The interest rate coupon is equivalent to the Reference Rate (TR) and is one of the components that define the profitability of savings and the FGTS (Service Time Guarantee Fund).
i.Sensitivity analysis
To determine the sensitivity of the Group's economic value to market movements, the mark-to-market (MTM) delta of assets and liabilities was calculated in different scenarios, considering relevant risk factors, during the analyzed period. The results that would negatively affect the Group's positions are presented below:
•Scenario 1: applying shocks of 1 basis point to interest rates and a 1% variation to prices (foreign currencies and stocks), based on available market information;
•Scenario 2: shocks of 25% variation in market curves and prices; and
•Scenario 3: shocks of 50% variation in market curves and prices.
It should be noted that the impacts reflect a static view of the portfolio. Market dynamism and portfolio composition fluctuations mean that these positions change continuously, not necessarily reflecting the Group's future position. The Group has an ongoing process for monitoring market risk and, in the event of a deterioration in its position or portfolio, implements mitigating actions to minimize potential negative effects.

g.Operational risk
Policy
Inter considers the management of operational risks strategic for the success, transparency, and longevity of its business. The adoption of best practices is essential for sustainability and growth.
Operational risk management aims to identify, assess, and monitor risks, and is defined as the risk of losses resulting from inadequate or faulty internal processes, people, and systems, or external events. This definition includes legal risk, but excludes strategic and reputational risk.
Operational risk events can be classified:
•Internal frauds;
•External frauds;
•Labor demands and poor workplace safety;
•Inappropriate practices relating to end users, customers, products and services;
•Damage to physical assets owned or used by the institution;
•Situations that lead to the interruption of the institution's activities or the discontinuation of services provided, including payments;
•Failures in information technology (IT) systems, processes or infrastructure; and
•Failures in the execution, meeting deadlines, or management of the institution's activities, including those related to payment arrangements.
For payment activities, the clauses include:
I - failures in the protection and security of sensitive data related to both end-user credentials and other information exchanged for the purpose of carrying out payment transactions;
II - failures in the identification and authentication of the end user in a payment transaction;
III - failures in the authorization of payment transactions; and
IV - failures in initiating payment transactions.
Inter adopts the management model of the three lines of defense in light of its size, business model and risk appetite.

Operational Risk Management
The operational risk management structure, including technological and cyber risks, promotes an organizational culture focused on prevention and effective risk management. This approach encompasses both a forward-looking view to anticipate future risks and a historical perspective to analyze trends and patterns of losses.
These procedures are supported by market tools, best practices based on international frameworks, a Risk Appetite Statement (RAS) approved by the Board of Directors, as well as a system of internal controls, independently assessed for their effectiveness and execution, in order to ensure compliance with the risk appetite limits defined by the Company.
7.Fair value of financial assets and liabilities
Financial instruments are classified into the following measurement categories:
•Fair value through profit or loss (FVTPL);
•Fair value through other comprehensive income (FVOCI); and
•Amortized cost.
The measurement of the fair value of a financial asset or liability is classified into one of three approaches based on the type of information used for valuation, known as fair value hierarchy levels:
•Level 1 – Includes financial instruments whose fair values are based on quoted (unadjusted) prices in active markets for identical assets or liabilities.
An active market is one in which transactions for the measured asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis.
•Level 2 – It includes assets and liabilities that do not have prices directly available in active markets, and are priced using conventional or internal models.
The methodology used for measuring financial assets and liabilities classified as "Level 2" employs observable information for the asset or liability at market: (i) quoted prices of similar items in an active market; (ii) identical items in an inactive market; or (iii) other information extracted from related markets.
•Level 3 – It utilizes unobservable information for the asset or liability, allowing the application of internal models and techniques.
The following table presents the composition of financial instruments according to their accounting classification: fair value through profit or loss (FVPL), fair value through other comprehensive income (FVOCI), and amortized cost. It also shows the carrying amounts and fair values of the financial instruments, including their levels in the fair value hierarchy. Inter does not include fair value information for financial assets and liabilities when the carrying amount is a reasonable approximation of fair value.

Loans and advances to customers, Amounts due from financial institutions, net of provision: Fair value is estimated for groups of loans with similar financial and risk characteristics, net of provision. It is calculated by discounting the projected cash flows of principal and interest to maturity, using a rate proportional to the risk associated with the estimated cash flows. The assumptions related to cash flows and discount rates are determined using market-available information and credit risk assessments associated with the customers.
Required reserves at the Central Bank of Brazil and cash and cash equivalents: The carrying amount of these instruments approximates their fair value.
Brazilian government bonds: Market-quoted prices are the best indicators of the fair values of these financial instruments.

|  |  |  | 30

| Notes to the interim condensed consolidated financial statement As of June 30,2026

Securities and Bonds Issued Abroad: Market-quoted prices are the best indicators of the fair values of these financial instruments, and can be priced using conventional or internal models, with inputs obtained directly or constructed from observations of active markets, or even generated by statistical and mathematical models.
Other Financial Assets and Liabilities: The carrying amounts of these instruments closely approximate their fair values.
Deposits from customers, deposits from banks and issued securities: These are calculated by discounting the estimated cash flows using market interest rates.
During the period ended June 30, 2026, there was no change in the measurement method for financial instruments that resulted in the reclassification of financial assets and liabilities between different levels of the fair value hierarchy.

11.Derivative financial instruments
Inter&Co engages in derivatives trading to meet its own needs and those of its clients, aiming to reduce exposure to market risks, exchange rate fluctuations, and interest rate variations.
These operations encompass various types of derivatives, such as forward contracts, futures, swaps, options, and credit derivatives.
Forward contracts: These are traded over-the-counter, where the buying or selling of financial or non-financial instruments takes place on a specific future date, at a pre-agreed price.
The main purpose of using forward contracts is to mitigate market risks arising from Inter's exposure and to meet client demands. Forward contracts involve the purchase or sale of a specific asset based on a pre-agreed price, with settlement on a future date.
Futures contracts: These are standardized contracts, traded on the stock exchange, that establish the purchase or sale of financial or non-financial instruments on a future date, at a fixed price.
The Group's objective in using futures contracts is to mitigate: (i) risks arising from exchange rate-linked exposures, including investments abroad; and (ii) risks arising from the mismatch between interest rates on active positions and funding rates.

| Notes to the interim condensed consolidated financial statement As of June 30,2026

Swap contracts: These are contracts that involve the exchange of cash flows or returns between two parties over a specified period, based on various indexers (such as interest rates, exchange rates, or commodity prices).
The swaps was carried out to mitigate the market risk associated with the mismatch between the indexers of the mortgage loan portfolio and the indexers of the funding portfolio.
Options contracts: These are contracts that grant the acquirer, through the payment of a premium, the right to buy or sell financial or non-financial assets/liabilities at a predetermined value during a specified period.

d.Hedge accounting - exposure
Inter&Co employs a risk management strategy through hedging operations, aiming to mitigate exposure to interest rates, exchange rate fluctuations, and cash flows. To more accurately reflect the economic results of these strategies in the financial statements, the results are presented using a hedge accounting approach, conducted in accordance with the strategy and purpose of the framework, which may include: (i) Cash Flow Hedge, (ii) Fair Value Hedge, and (iii) Net Investment Hedge in a foreign subsidiary.

|  |  |  | 36

| Notes to the interim condensed consolidated financial statement As of June 30,2026

The hedge accounting structure is periodically evaluated throughout its term using two complementary approaches: (i) Portfolio Coverage Percentage: Inter&Co seeks to maintain coverage aligned with the economic strategies adopted by the institution, observing the balance between the effectiveness of the protection and the economic optimization of the structure, with the hedge ratio defined based on the identified exposure and the designated hedging instrument; (ii) Prospective and Retrospective Effectiveness: evaluated with the objective of demonstrating and monitoring the existence of a valid economic relationship between the hedged item and the designated hedging instrument, which can be determined qualitatively and/or quantitatively, through scenario testing of the main market variables.
In this context, part of the result of the structure may be recognized directly in the income statement or in Other Comprehensive Income (OCI) in Equity, net of tax effects, being transferred to the income statement in case of ineffectiveness or liquidation of the hedging structure.

(a) The hedging instrument used is NDFs (Non-Deliverable Forwards). The hedged item consists of government bonds issued abroad, considered low-risk, with varying maturities and without periodic interest payments. This group designates only the variations in the fair value of the spot component of foreign exchange forward contracts with a hedging instrument in cash flow hedging relationships. The variations in the fair value of the forward component of such contracts are accounted for separately as hedging costs and recognized in Other Comprehensive Income;
(b) The instrument is being presented in the line item "derivative financial assets" of the balance sheet. The effect of the result is shown in the line item "income from securities, derivatives and foreign exchange" of the consolidated income statements; and
(c) Cash flow hedge reserves represent the accumulated amount related to changes in the instrument reclassified to ORA since the inception of the hedge accounting framework.
Banco Inter executed a cash flow hedge operation to protect securities issued abroad, which began on September 25, 2025, and ended on March 19, 2026. The hedge reserve of R$ 1,067, which was allocated to Other Comprehensive Income, was reclassified to the period's profit or loss.

(a) For its financial assets, the Institution establishes expected losses that cover both the used and unused amounts of loan commitments. The expected loss relating to the unused amount is provisioned in liabilities.
a.Provisions for legal an administrative proceedings
The legal entities of the Group, in the normal course of their activities, are parties to legal proceedings of a fiscal (tax and social security), labor, and civil nature. The respective provisions were established taking into account current laws, applicable regulations, the opinion of legal advisors, the nature and complexity of the cases, case law, past experience, and other relevant criteria, in order to allow for the most accurate estimate possible.
i.Labor lawsuits
These are lawsuits aimed at obtaining compensation for labor-related claims. The provisioned amounts mostly relate to cases discussing potential labor rights, such as claims for overtime and salary equalization. At Inter&Co, the methodology used for provisioning these contingencies is based on calculating the average value of completed labor lawsuits, considering the total value of finalized cases divided by the amount actually disbursed in the last 36 months.

| Notes to the interim condensed consolidated financial statement As of June 30,2026

ii.Civil lawsuits
These claims primarily seek compensation for material and moral damages related to the Group's products and services, including declaratory and compensatory actions, issues concerning compliance with limits for payroll deductions for borrowers, requests for document submission, and contract review actions. Inter&Co's provisioning methodology for these contingencies is based on calculating the average value of completed civil lawsuits, obtained by dividing the total value of settled cases by the amount actually paid in the last 24 months.

b.Contingent tax liabi lities classified as possible losses
The main proceedings with this classification are:
i.Income tax and social contribution on net income – IRPJ and CSLL
On August 30, 2013, an infraction notice was issued (referring to expenses considered non-deductible) demanding the collection of income tax and social security contributions related to the calendar years 2008 and 2009. As of June 30, 2026, the amount at risk from the lawsuit totals R$30,635 (December 31, 2025: R$32,147), while the total amount of the lawsuit corresponds to R$69,113 (December 31, 2025: R$67,145).
ii.COFINS
Inter is challenging COFINS assessments for the period from 1999 to 2014.
Before the publication of Law No. 12,973/14, which modified the understanding regarding the inclusion of financial revenues in the calculation basis of COFINS (Social Security Financing Contribution), there was discussion about expanding the calculation basis of said contribution, as promoted by §1 of Article 3 of Law No. 9,718/98.
In 2005, Inter obtained a final and favorable ruling from the Supreme Federal Court that ensured the financial institution's right to collect COFINS (Social Security Financing Contribution) based only on revenue from services rendered, instead of total revenue that would include financial revenue.
Between 1999 and 2006, Inter made judicial deposits and/or paid the obligation. In 2006, following a favorable decision by the Supreme Federal Court and the express consent of the Federal Revenue Service, Inter's judicial deposit was released. Additionally, the authorization to use the credits, for amounts previously overpaid against current obligations, was approved without contestation by the Federal Revenue Service on May 11, 2006. Subsequently, the Federal Revenue Service questioned the procedures adopted by Inter, applying the understanding that financial revenues should be included in the COFINS tax base.
After the publication of Law 12.973/14, Inter modified its procedures to include financial revenues in the calculation base of COFINS, so that the taxable events involved in Inter's discussions are all prior to the law.

| Notes to the interim condensed consolidated financial statement As of June 30,2026

Currently, the application of res judicata in a separate legal action that secured Inter's right not to pay COFINS on its financial revenues is being discussed, so the Supreme Federal Court's ruling on Topic 372 does not directly affect Inter's discussions. As of June 30, 2026, the value at risk of the action totals R$78,061 (December 31, 2025: R$73,000), while the total value of the action corresponds to R$174,533 (December 31, 2025: R$163,268).

33.Share-based payment
a.Share-based compensation agreements
a.1) Stock option plan - Banco Inter S.A.
Between February 2018 and January 2022, Banco Inter S.A. established stock option programs through which stock options were granted to Inter's management and executives for the acquisition of Banco Inter S.A. shares.
On January 4, 2023, an Extraordinary General Meeting of Inter&Co, Inc. was held, at which the migration of share-based payment plans was approved, with the consequent assumption by Inter&Co of Banco Inter S.A.'s obligations arising from the active plans and respective programs. As a result of the corporate reorganization, the number of options held by each beneficiary was proportionally adjusted. Thus, for every 6 stock options of ordinary or preferred shares of Banco Inter S.A., the beneficiary will have 1 stock option of Inter&Co Class A Share. Additionally, the re-pricing of the exercise price of options granted in 2022, which had not yet been exercised, was approved. Upon re-pricing, a new calculation of the fair value of the granted and unexercised options was performed, resulting in an additional amount of R$ 15,990 of incremental expense, to be recognized over the remaining vesting period.
The main characteristics of the plans are described below:

Grant Date |  | Final strike date |  | Options (shares INTR) |  | Vesting |  | Average strike price |  | Participants
02/15/2018 |  | 02/15/2025 |  | 5,452,464 |  | Up to 5 years |  | R$1.80 |  | Officers, managers and key employees
07/09/2020 |  | 07/09/2027 |  | 3,182,250 |  | Up to 5 years |  | R$21.50 |  | Officers, managers and key employees
01/31/2022 |  | 12/31/2028 |  | 3,250,000 |  | Up to 5 years |  | R$15.50 |  | Officers, managers and key employees

| Notes to the interim condensed consolidated financial statement As of June 30,2026

The fair value of the 2020 plan were estimated based on the Black & Scholes option pricing model considering the terms and conditions under which the options were granted, and the respective compensation expense is recognized during the vesting period.

|  |  |  | 2020
Strike price |  |  |  | 21.50 |
Risk-free rate |  |  |  | 9.98 | %
Duration of the strike (years) |  |  |  | 7
Expected annualized volatility |  |  |  | 64.28 | %
Fair value of the option at the grant/share date: |  |  |  | 0.05 |

For the 2022 program, the fair value was estimated based on the Binomial model:

|  | 2022
Strike price |  | 15.50 |
Risk-free rate |  | 11.45 | %
Duration of the strike (years) |  | 7 |
Expected annualized volatility |  | 38.81 | %
Weighted fair value of the option at the grant/share date: |  | 4.08 |

For the period ended June 30, 2026, R$ 4,797 in employee benefit expenses were recognized (June 30, 2025: R$ 10,073).
a.2) Share-based payment related to Inter & Co Payments Inc., acquisition
In the context of Inter's acquisition of Inter & Co Payments, Inc., it was established that part of the payments to the acquired Company's senior executives would be effected through the conversion of Inter & Co Payments, Inc.'s share-based payment plan, with an amendment providing that the stock options could be exercised for Inter&Co Class A shares and/or Inter&Co restricted Class A shares, as applicable, in lieu of Inter & Co Payments, Inc. shares. Given the terms and conditions of the agreement executed between the parties, the expenses related to the granted options were treated as share-based payment expense recognized over the vesting period of the options and contingent upon the continued employment of such key management personnel.
All put options that had been granted were exercised, with the last tranche exercised on January 7, 2025.
All call options granted under the Inter & Co Payments, Inc. share-based payment plan, migrated to Inter & Co, were exercised and the shares were fully transferred to the beneficiary key executives by October 31, 2025, the total number of these shares is 489,386.
Due to the completion of the aforementioned transactions, the share-based payment plan of Inter&Co Payments, Inc., has been terminated and discontinued.
a.3) Restricted shares agreement (RSU) - Inter.
The Extraordinary General Meeting of Inter&Co, Inc. held on January 4, 2023 approved the creation of the Omnibus Incentive Plan, which aims to promote the interests of the Company and its shareholders, strengthening the Company's ability to attract, retain and motivate employees who are expected to make contributions to the Company and provide to these individuals with incentives to align their interests with those of the Company's shareholders.

36. Other information
Consumer Tax Reform
On January 16, 2025, Complementary Law No. 214/2025 was published, resulting from the conversion of PLP No. 68/2024, integrating the regulation of Constitutional Amendment No. 132/2023, which establishes the Tax Reform on Consumption. This law provides, among other aspects, for the creation of three new taxes: the Tax on Goods and Services (IBS), the Contribution on Goods and Services (CBS), and the Selective Tax (IS), representing a significant milestone in the modernization of the national tax system.
On January 13, 2026, Complementary Law No. 227, derived from PLP No. 108/2024, was enacted, creating the IBS Management Committee (CGIBS) and establishing the general rules for its administration, oversight, collection, and revenue distribution. The law also defined the IBS/CBS rates applicable to financial services for the period from 2027 to 2033, with a progressive increase from 10.85% to 12.50%. Conversely, for fees currently subject to ISS (Service Tax), a reduction in the rate from 2% to 1.2% is foreseen for the same period.
Inter&Co is monitoring the evolution of regulations and the publication of supplementary rules necessary for the implementation of the new tax model. The potential financial and operational impacts resulting from these changes are still under evaluation and await supplementary regulations for a final analysis of the aforementioned impacts.
