Shareholder’s equity

Shareholder’s equity totaled R$10.4 billion, a growth of 0.2% compared to December 31, 2025.

Inter adopts a capital remuneration policy by distributing interest on equity in the same proportion as their share of the capital, calculated in accordance with current legislation. This interest, net of withholding income tax, is included in the calculation of mandatory dividends for the fiscal year as stipulated in the Articles of Association and Article 202 of Law No. 6,404/1976.

Relationship with the independent auditors

The Company informs that it has a policy with requirements for contractual risk analysis, which defines that the Board of Directors must evaluate the transparency, objectivity, governance aspects, and commitment to the independence of the contracting process, thus ensuring compliance between the parties involved. 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 March 31, 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.

Acknowledgment

We would like to thank our shareholders, customers, and partners for their trust, as well as each of our employees who build our history each day.

Notes to the interim condensed consolidated financial statement<br><br>As of March 31,2026

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 de facto control over an investee;

•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 impairment testing purposes, each investee entity was considered a cash-generating unit (“CGU”);

•Deferred tax asset (see note 32): the expectation of realization of 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): Measuring provisions for expected credit losses on financial assets measured at amortized cost requires the use of complex quantitative models and assumptions about future macroeconomic conditions and credit behavior. Several significant judgments are also required 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 the provision for legal proceedings. The main assumptions considered relate to the probability and magnitude of resource outflows.

3.New accounting standards recently issued

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, the 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 material 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: aim to define control and provide transition guidance after the application of the new concept, as well as clarifications on the sale or contribution of assets between related entities, 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 9 – Financial Instruments: includes clarifications on the derecognition of lease liabilities and their implications, effective from January 1, 2026. Management has not identified any significant impacts from these changes on its consolidated condensed interim financial information.

Other new rules and interpretations have been issued, but have not yet come into effect

•IFRS 18 - Presentation and Disclosure in Financial Statements: issued in April 2024, it replaces IAS 1 and introduces additional requirements for financial statements with the aim of improving information for shareholders. It defines three categories for income and expenses: operating, investing, and financing, in addition to including new subtotals. The standard also provides guidance on the disclosure of performance indicators defined by management and includes 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, this standard defines that a subsidiary without public responsibility 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.

5.Operating segments

The operating segments are disclosed based on internal information used by the principal responsible for operational decisions to allocate resources and evaluate performance. The principal responsible for operational decisions, including allocating resources, evaluating the performance of operating segments, and making strategic decisions for Inter&co, is the CEO in conjunction with the Board of Directors.

Profit by operating segment

Each operating segment is composed of one or more legal entities. The measurement of profit by operating segment takes into account all revenues and expenses recognized by the companies that make up each segment.

Transactions between segments are carried out with terms and rates consistent with those practiced with third parties, when applicable. The Group does not have any client responsible for more than 10% of its total net revenue.

a.Banking & Spending

This segment includes banking products and services such as checking accounts, debit and credit cards, deposits, loans, customer advances, debt collection activities, and other services provided to customers, primarily through the Inter app. Also included in this segment are foreign exchange services, intercountry remittances, including the Global Account digital solution, smart card payment solutions (including Inter Pag), along with the investment funds consolidated by the Group.

b.Investments

This segment is responsible for operations related to the purchase, sale, and custody of securities, structuring and distribution of securities in the capital market, and operations related to the management of fund portfolios and other assets (purchase, sale, risk management). Revenues are mainly derived from commissions and management fees charged to investors for these services.

c.Insurance Brokerage

This segment, insurance products are offered that are underwritten by insurance companies with which Inter has agreements (“partner companies”), including guarantees, life, property and auto insurance, and pension products, as well as consortium products provided by a third party with whom Inter has a commercial agreement. Insurance sales commission revenues, net of cancellations, are recognized in the income statement when the services are effectively rendered, i.e., upon completion of the sale to the client, when the performance obligation is fulfilled.

d.Inter Shop

This segment includes sales of goods and/or services to Inter's clients through its partners, via our digital platform; as well as the initiative to offer BNPL (Buy Now Pay Later) operations to clients. Segment revenues substantially comprise commissions received from sales and/or the provision of these services.

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 associated with the borrower's or counterparty's failure to meet their respective financial obligations under the agreed terms, or the devaluation of a credit contract resulting from an increased risk of default by the borrower, among other factors.

Financial instruments subject to credit risk undergo rigorous credit assessment prior to contracting, as well as throughout the term of the respective transactions. Credit analyses are based on the economic and financial capacity of the borrower or counterparty, their behavior, including payment history, credit reputation, and the terms and conditions of the respective credit transaction, including terms, rates, and guarantees.

The table belows presents the maximum credit risk exposure of financial assets and liabilities:

		03/31/2026		12/31/2025
Financial Assets	Note	Gross value	Expected loss	Gross value	Expected loss
Cash and cash equivalents	8	4,296,629	—	3,801,513	—
Amounts due from financial institutions	9	4,045,025	(10,276)	4,313,571	(1,211)

Securities	10	27,366,631	(25,775)	29,057,040	(46,717)
Loans and advances to customers	12	49,822,075	(3,336,710)	48,251,180	(3,000,076)
Other assets (a)	15	107,807	(808)	114,483	(858)
Total		93,525,929	(3,373,569)	93,405,445	(3,048,862)
Financial liabilities
Loan commitments	21	19,684,534	(161,198)	26,750,795	(204,867)
Financial guarantees	21	692,060	(5,741)	645,589	(5,125)
Total		20,376,594	(166,939)	27,396,384	(209,992)

(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;

Notes to the interim condensed consolidated financial statement<br><br>As of March 31,2026

•Real estate loans: loan and financing operations secured by real estate, with attached collateral;

•Personal loans: loan and payroll deduction card transactions, personal loans 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, requirements, selection, evaluation, formalization, control, and reinforcement of guarantees, aiming to ensure the adequacy and sufficiency of mitigating instruments throughout the loan cycle.

In 2026, there were no material changes in the nature of credit risk exposures, how they arise, or the Group's objectives, policies, and processes for managing them, although Inter&Co continues to improve its internal risk management processes.

To fall due in more than 12 months	27,502,132	25,946,070
Total	49,822,075	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 proposed 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;

Notes to the interim condensed consolidated financial statement<br><br>As of March 31,2026

▪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.

	03/31/2026	12/31/2025
Less than or equal to 30%	2,691,868	2,565,053
Greater than 30% and less than or equal to 50%	4,648,193	4,432,991
Greater than 50% and less than or equal to 70%	7,126,664	6,646,170

Greater than 90%	122,646	134,603
Total	17,330,928	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<br><br>As of March 31,2026

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 March 31, 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.

Notes to the interim condensed consolidated financial statement<br><br>As of March 31,2026

The value-at-risk for the Trading Book positions are as follows:

Risk factor	03/31/2026		12/31/2025
IPCA Coupon (a)	6,422		5,370
Fixed rate	1,381		401
USD Coupon	13,141		5,734
Foreign currencies	41,298		18,740
Share price	352		70
Subtotal	62,594		30,315
Diversification effects (correlation)	19,610		12,270
Value-at-Risk	42,984		18,045
VaR over assets	0.04	%	0.03	%

(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).

The VaR of the banking portfolio are as follows:

Risk factor	03/31/2026		12/31/2025
IPCA Coupon (a)	1,425,079		869,347
Fixed rate	120,459		74,245
TR Coupon (b)	65,764		34,499
Others	102,243		294,141
Subtotal	1,713,545		1,272,232
Diversification effects (correlation)	217,252		325,523
Value-at-Risk	1,496,293		946,709
VarR over assets	1.50	%	0.96	%

(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).

a.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.

b.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.

Notes to the interim condensed consolidated financial statement<br><br>As of March 31,2026

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, Loans and advances to 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.

Notes to the interim condensed consolidated financial statement<br><br>As of March 31,2026

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 with customers, deposits with financial institutions, and issued securities: These are calculated by discounting the estimated cash flows using market interest rates.

During the period ended March 31, 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.

8.Cash and cash equivalents

Reverse repurchase agreements (a)	2,433,495	663,141
Total	4,296,629	3,801,513

(a) Refers to transactions whose maturity, on the date of application, was equal to or less than 90 days and present an insignificant risk of change in fair value. Due to the short term and low volatility of these financial instruments, no provision for losses was established, since the credit risk is considered minimal and there is no expectation of significant variations in market value until maturity.

11.Derivative financial instruments

The accounting policy on Derivatives is presented in Note 4, item e.

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.

Notes to the interim condensed consolidated financial statement<br><br>As of March 31,2026

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.

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

The accounting policy regarding Hedge Accounting is presented in explanatory note 4 e.

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.

Notes to the interim condensed consolidated financial statement<br><br>As of March 31,2026

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.

i.Cash Flow Hedge

	Hedging Instruments (a)							Hedged Items
Strategy	Nominal amount	Carrying amount (b)	Changes in the value of the hedging instrument recognized in OCI	Hedge ineffectiveness recognized in statements of income	Hedge costs recognized in OCI	Amount reclassified from the hedge reserve to statements of income	Amount reclassified from the hedge costs reserve to statements of income	Changes in fair value used for calculating hedge ineffectiveness	Hedge costs reserve (c)	Cash flow hedge reserve (c)	Balances remaining in the cash flow reserve from hedging relationships for which hedge accounting is no longer applied

(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 ORA (Operational Revenue Account); In March 2025, the hedged object also included obligations to suppliers, which were protected with dollar futures (a hedging instrument);

(b) The object is being presented under the heading "Securities and Financial Instruments," net of provisions for expected losses; the instrument is being presented under the heading "Derivative Financial Instruments" in the balance sheet. The effect of the result is demonstrated in the heading "Net Interest Income and Revenue from Securities, Derivatives and Foreign Exchange" in the consolidated income statement; and

(c) Hedge Cost Reserve and Cash Flow hedge represent the accumulated amount related to changes in the instrument reclassified to ORA since the inception of the hedging 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$1.061, which was allocated to Other Comprehensive Income, was redirected to Profit or Loss.

Transfers between stages are calculated based on an end-to-end view, comparing the status of contracts on 01/01/2026 and 03/31/2026 to identify the amounts migrated between stages on the respective dates. Changes in the type of credit operations do not constitute a new "Origination" and are therefore considered in the "Transfer between stages" columns.

(a) In the transitions between stage 1 and stage 3, a significant portion of the operations passed through stage 2 during the period.

(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<br><br>As of March 31,2026

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 liabilities 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 March 31, 2026, the amount at risk from the lawsuit totals R$ 32,617 (December 31, 2025: R$ 32,147), while the total amount of the lawsuit corresponds to R$ 68,130 (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<br><br>As of March 31,2026

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 March 31, 2026, the value at risk of the action totals R$ 76,905 (December 31, 2025: R$ 73,000), while the total value of the action corresponds to R$ 171,953 (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

Changes in the options of each plan for the period ended March 31, 2026 and supplementary information are shown below:

Grant Date	12/31/2025		Granted		Expired/Cancelled	Exercised	03/31/2026

---

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 March 31, 2026, R$ 2,313 in employee benefit expenses were recognized (March 31, 2025: R$ 3,429).

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.
