How this balance works

Rhea-AI gives every point it takes from this document a weight. Minor counts 1, Moderate 3 and Major 9, so one Major point outweighs several Minor ones. The bar adds up the weights on each side, and when neither side holds more than 65% of the total the balance reads Mixed.

It reads the document as published, with the same rules for every company, and it does not look at what the market expected or at how the stock traded, so a point can be objectively good on a day the stock falls.

Rhea-AI Sentiment measures something else, the tone of the wording.

expected credit losses financial

"provisions for expected credit losses"

Expected credit losses are an accounting estimate of how much a lender or company expects to lose when borrowers or customers don’t fully pay what they owe, combining how likely nonpayment is with how big the loss would be. Investors care because these estimates determine how much a firm must set aside from earnings as a reserve, directly affecting reported profits, balance-sheet strength and perceptions of credit risk—like setting aside a rainy-day fund for unpaid bills.

fair value through other comprehensive income financial

"Fair value through other comprehensive income - FVOCI"

An accounting classification for certain financial assets where changes in market value are recorded at current market prices, but unrealized gains and losses are sent to a separate equity “holding” area called other comprehensive income instead of appearing in reported profit or loss. Think of it like marking a painting to its gallery price and placing the paper gains in a locked box until the painting is sold; this reduces headline profit volatility but still affects the company’s net worth, so investors watch it to judge true economic exposure and future earnings when assets are sold.

Value-at-Risk financial

"The value-at-risk for the Trading Book positions"

Value-at-risk (VaR) estimates the largest loss an investment or portfolio is likely to suffer over a specific time frame at a given probability level — for example, the amount you would expect to lose or exceed only 5% of the time. Think of it like a weather forecast for losses: it gives a commonly agreed threshold for how bad things might get. Investors use VaR to set risk limits, compare portfolios, and decide how much capital to hold against potential losses.

Loan to Value (LTV) financial

"ratio between the value of a loan and the value of the financed asset"

Probability of Default (PD) financial

To enhance the presentation, level of detail and clarity of the financial statements, certain reclassifications were made in the financial statements.

Consequently, there was no material impact on the financial statements, which remain comparable across the periods presented. Additional explanations for each reclassification are provided in the explanatory notes.


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

The functional currency of the Group companies is shown in explanatory note 4, 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 statements, 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 key 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 4): 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 (SPPI 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 applicable to the management of financial assets and verification of the characteristics of the contractual cash flows of financial instruments (SPPI test);

•Business combination (see note 4): 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;


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

•Provision for expected credit losses (see notes 12c and 21): measuring provisions for expected credit losses on financial assets measured at amortized cost, credit commitments, outstanding credits, 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.

5.Operating segments

The operating segments are disclosed based on internal information used by the CEO and Board of Directors of Inter&Co for resource allocation, performance evaluation, and strategic decision-making.

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. No single client is responsible for more than 10% of the Group's 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 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.

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), as well as the administration of investment funds. Revenues are mainly derived from commissions and management fees charged to investors for these services.

c.Insurance Brokerage

This segment offers insurance products underwritten by insurance companies with which Inter has an agreement (“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.

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.

Below is the maximum exposure to credit risk for financial assets and liabilities:


		09/30/2026		12/31/2025
Financial assets	Note	Gross value	Expected loss	Gross value	Expected loss
Cash and cash equivalents	8	4,186,380	—	3,801,513	—
Amounts due from financial institutions	9	4,251,280	(998)	4,313,571	(1,211)
Deposits at Central Bank of Brazil		8,825,330	—	7,867,658	—
Securities	10	30,381,994	(42,023)	29,057,040	(46,717)
Loans and advances to customers	12	54,554,242	(3,877,824)	48,251,180	(3,000,076)
Other financial assets	15	588,916	(1,426)	651,808	(858)
Total		102,788,142	(3,922,271)	93,942,770	(3,048,862)

Financial liabilities
Loan commitments	21	17,316,086	(198,625)	26,750,795	(204,867)
Financial guarantees	21	650,561	(4,694)	645,589	(5,125)
Total		17,966,647	(203,319)	27,396,384	(209,992)

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 As of September 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

With the goal of maintaining exposures within the risk levels established by Management, Inter&Co adopts structured measures to mitigate credit risk. This mitigation is achieved through the structuring of guarantees, adapting the risk level to the characteristics of the guarantees provided at the time of granting. Risk indicators are continuously monitored, and alternative mitigation proposals 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.

To fall due in more than 12 months	29,699,538	25,946,070
Total	54,554,242	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 statements and qualitative analyses from experts;

▪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


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

▪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.


	09/30/2026	12/31/2025
Less than or equal to 30%	3,079,389	2,565,053
Greater than 30% and less than or equal to 50%	5,292,720	4,432,991
Greater than 50% and less than or equal to 70%	7,285,225	6,646,170
Greater than 70% and less than or equal to 90%	4,067,069	2,415,905
Greater than 90%	173,644	134,603
Total	19,898,047	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 (led by the Chief Risk Officer - CRO). Specifically, the Risk Management Office is responsible for the continuous monitoring and tracking of liquidity risk exposure.

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.

•Analysis of the mismatch between assets and liabilities, net inflows, and maturity forecasts;

•Monitoring of liquidity limits and ratios;


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

•Investor concentration 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 September 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.

d.Analyses of financial instruments by remaining contractual term

(a) Other financial assets consist substantially of advance payments on foreign exchange contracts, commissions and bonuses receivable, and premiums or discounts on financial asset transfer transactions;

(b) In general, fixed-term deposits (CDBs) are issued with an early liquidity clause, and the client (counterparty) can redeem them at any time. For disclosure purposes, CDBs are allocated according to the number of days remaining until maturity. However, for risk management purposes, considering both market risk and liquidity risk, a methodology (statistical behavior model) is used that focuses on allocating positions (CDBs) to a more likely maturity date;

(d) The observed mismatches stem from the different characteristics and contractual terms of the financial assets and liabilities, and do not necessarily represent limitations in the institution's effective liquidity position.

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 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.

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


Risk factor	09/30/2026		12/31/2025
Foreign currencies	19,465		18,740
Fixed rate	8,988		401
Stock prices	1,666		70
IPCA coupon (a)	1,141		5,370
USD coupon	753		5,734
Subtotal	32,013		30,315

Diversification effects (correlation)	14,417		12,270
Value-at-Risk	17,596		18,045
VaR over assets	0.02	%	0.02	%

(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	09/30/2026		12/31/2025
IPCA coupon (a)	345,749		869,347
TR coupon (b)	48,747		34,499
Fixed rate	15,099		74,245
Others	98,585		294,141
Subtotal	508,180		1,272,232

Diversification effects (correlation)	120,677		325,523
Value-at-Risk	387,503		946,709
VaR over assets	0.36	%	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).

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 into the following categories:

•Internal frauds;

•External frauds;

•Labor demands and poor workplace safety;

•Inappropriate practices relating to end users, customers, products and services;


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

•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.


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

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.

Total	—	84,489,405	—	84,489,405	84,413,427

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.


			Notes to the interim condensed consolidated financial statement As of September 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.

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 September 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.

8.Cash and cash equivalents


	09/30/2026	12/31/2025
Cash and equivalents in foreign currency	1,803,098	2,891,189
Cash and equivalents in national currency	337,078	247,183
Reverse repurchase agreements (a)	2,046,204	663,141
Total	4,186,380	3,801,513

(a) This refers to transactions whose maturities, at the time of application, were 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.

9.Amounts due from financial institutions, net of provisions for expected credit losses


	09/30/2026	12/31/2025
Loans to financial institutions (a)	4,251,280	4,313,571
Interbank deposit investments	376,066	267,305

Expected credit loss (a)	(998)	(1,211)
Total	4,954,638	4,600,218

(a) It refers essentially to the anticipation of receivables and amounts to be received from card issuers, net of expected losses.

As of September 30, 2026, the expected loss on securities totaled R$42,023, broken down as follows: R$35,274 (83.9%) in stage 1, R$192 (0.5%) in stage 2, and R$6,557 (15.6%) in stage 3. As of December 31, 2025, the expected loss totaled R$46,717, broken down as follows: R$28,259 (60.5%) in stage 1, R$4,981 (10.7%) in stage 2, and R$13,477 (28.8%) in stage 3.

Inter&Co classifies R$26,815,849 (88.4%) of the portfolio as low credit risk, mainly due to the predominance of Federal Government Bonds (Brazil and Abroad). For this reason, no provisions for expected credit loss are made on this portion (As of December 31, 2025, it totaled R$26,253,904 (90.5%)).

The remaining R$3,524,122 (11.6%) of the portfolio corresponds to assets that have inherent credit risk, and therefore are subject to evaluation for the establishment of provisions (As of December 31, 2025, it totaled R$2,756,419 (9.5%)).

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: They 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 objective 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.

Swap contracts: These are contracts that involve the exchange of cash flows or returns between two parties over a specified period, based on various benchmark rates (such as interest rates, exchange rates, or commodity prices).


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

The swaps were carried out to mitigate the market risk associated with the mismatch between the benchmark rates of the mortgage loan portfolio and 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 be: (i) Cash Flow Hedge, (ii) Fair Value Hedge, and (iii) Net Foreign Investment Hedge.

In this context, part of the result of the structure may be recognized directly in the income statement or in Other Comprehensive Income in Equity, net of tax effects, being transferred to the income statement in case of ineffectiveness or liquidation of the hedging structure.


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

In hedge accounting, risk factor groups include:

• Interest Rate: Risk of loss in transactions subject to interest rate fluctuations.

• Exchange Rate: Risk of loss in transactions and/or investments subject to exchange rate fluctuations.

The structures designated for risk factor groups are implemented considering the risks in their entirety, when compatible hedging instruments exist. By decision of Management, in some cases, the risks are protected by the term and risk factor limit of the hedging instrument.

Derivatives are used to protect the cash flows and fair value of the instruments designated as the hedged item.

Hedging relationships are established with the objective of reducing volatility arising from exposures to financial risks identified by the Institution. The evaluation, monitoring, and measurement of the effectiveness of these relationships are conducted by the Risk area, which continuously monitors the evolution of the hedged exposures. Risk management is carried out through the continuous evaluation of the economic relationship between hedging instruments and their respective hedged assets, with the expectation that the value variations resulting from the hedged risks, in the instruments and the assets, will exhibit opposite and proportionally equivalent behaviors. In this way, the aim is for the effects of the hedged exposures to be offset by the variations in the hedging instruments, mitigating the Institution's exposure to the identified risk factors.

Inter&Co maintains individual and portfolio hedging strategies, encompassing sets of managed positions based on common risks. Whenever necessary, hedging relationships are evaluated to ensure that the designated instruments continue to adequately reflect the risk management strategy and underlying economic exposures.


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

i.Cash Flow Hedge

Inter&Co Inc. carried out 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.

Cash flow hedging operations are designed to mitigate Inter&Co's exposure to exchange rate fluctuations associated with future cash flows from government bonds issued abroad. These instruments form part of Inter&Co's market risk management strategy, aiming to reduce the volatility of results and preserve the predictability of cash flows arising from these assets.

The hedged items correspond to securities issued abroad whose cash flows are exposed to exchange rate fluctuations. The hedged risk refers specifically to the exchange rate variation affecting the expected future cash flows of these financial instruments.

As hedging instruments, Inter&Co uses Non-Deliverable Forward (NDF) contracts, through which it seeks to neutralize, totally or partially, the impacts of exchange rate fluctuations on the cash flows of the hedged items. Hedging relationships are formally documented on the date of their designation, and their effectiveness is periodically evaluated in accordance with applicable accounting requirements and internal risk management practices.

The main potential sources of ineffectiveness in cash flow hedging relationships stem from differences in maturity or volume between the cash flows of the hedged items and those of the hedging instruments, changes in the expected settlement dates of the hedged flows, and changes in the credit risk of counterparties or Inter itself, which may affect the pricing of derivatives. Additionally, any mismatches between the terms of NDF contracts and the characteristics of the cash flows of the hedged securities, including differences in maturity, benchmark rates, or notional amounts, may generate accounting ineffectiveness. Inter&Co continuously monitors these exposures through periodic effectiveness assessments, seeking to ensure that the economic relationship between the hedging instruments and the hedged items remains consistent with the established risk management objectives.

The table below presents the effects of the hedge accounting on the financial position and financial performance of Inter&Co:


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


	Hedging Instruments (a)							Hedged Item
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 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 demonstrated 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 OCI since the inception of the hedge accounting framework.

ii.Fair Value Hedge

Fair value hedges are designed to mitigate exposure to changes in fair value attributable to the interest rate risk component of the credit portfolios (SIAPE, Home Equity, FGTS, SFH, Mortgage loan and INSS) and of Real Estate Receivables Certificates (CRI). The items designated as hedged correspond to these financial assets, while the hedged risk refers to changes in their fair value resulting from movements in market interest rates. As hedging instruments, Inter&Co uses index futures contracts traded on the B3. Inter&Co periodically evaluates the effectiveness of hedging relationships to ensure that changes in the fair value of the hedging instruments compensate, within the established parameters, for variations observed in the hedged items.

Potential sources of ineffectiveness include differences between the terms of index futures contracts and the characteristics of the hedged assets, especially regarding maturity dates and indexation bases. They also include interest rate behavior and the deterioration of the loan portfolio. Additionally, specific pricing factors for assets linked to credit rates and real estate receivables certificates (CRIs), factors not directly related to the interest rate derivatives used in the hedging relationship, can generate fair value fluctuations not compensated by the hedging instruments. Although the instruments are structured to maintain an economic relationship with the hedged items, such differences may result in the recognition of ineffectiveness in the outcome. Inter&Co continuously monitors the effectiveness of these relationships to ensure their alignment with the established risk management objectives.

The table below presents the effects of the hedge accounting on the financial position and financial performance of Inter&Co:


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


	Hedging Instruments				Hedged Item (c)
Strategy	Nominal amount	Carrying amount	Changes in fair value used for calculating hedge ineffectiveness	Hedge ineffectiveness recognized in statements of income	Carrying amount	Adjustment to gross fair value recorded in the statement of income	Accumulated amount of fair value hedge adjustments on the hedged item

(a) The hedging instrument used is the DI Future Rate. The hedge covers loan portfolios, including early withdrawal of FGTS (Brazilian employee severance fund) and payroll loans;

(b) The hedging instrument used is the DAP (IPCA Coupon). The hedged item covers a firm commitment to purchase and stock of Real Estate Receivables Certificates; and

(c) The item is presented under the heading "loans and advances to customers, net of provisions for expected losses," and the instrument is presented under the heading "derivative financial instruments" in the balance sheet. The effect of the result is shown in the net interest income section of the consolidated income statement.

iii.Foreign Investment Hedge

Foreign net investment hedging operations are designed to mitigate Inter&Co's exposure to exchange rate fluctuations arising from investments made in subsidiaries located abroad. This strategy aims to reduce the impact on consolidated equity of exchange rate fluctuations affecting investments held in foreign currencies.

The hedged items correspond to the net investments held in these subsidiaries, with the hedged risk substantially represented by the exchange rate variation resulting from the conversion of these investments into Inter&Co's functional currency. For hedging purposes, currency futures contracts traded on the B3 are used, which are formally designated as hedging instruments.

Hedging relationships are documented at the time of their designation, and their effectiveness is evaluated periodically in accordance with applicable accounting and regulatory requirements, as well as Inter&Co's internal risk management policies.

Potential sources of ineffectiveness include differences between the value of net investments held in foreign subsidiaries and the notional value of currency futures contracts designated as hedging instruments. These differences may arise from capital contributions, reductions, retained earnings, or other movements that impact the value of the hedged investments. Additionally, exchange rate fluctuations associated with components not included in the hedging relationship and potential maturity mismatches may result in the recognition of ineffectiveness. Although hedging instruments are structured to maintain an economic relationship with the net investments hedging, residual differences may affect the degree of compensation between the hedging instruments and the hedged items. Inter&Co continuously monitors these hedging relationships to ensure their alignment with the risk management strategy and applicable accounting requirements.

Starting with the release of the first quarter of 2026, transfers between stages are calculated based on an end-to-end view, comparing the position of contracts on 01/01/2026 and at the end of the reference period of the release to identify the amounts migrated between stages on the respective dates. Transactions agreed upon after the initial date are allocated to the "Net Variation" column and reflect the stage they are in at the end of the reference period.

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

Total	269,767	265,455

(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 and administrative proceedings

The Group's legal entities, 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 obtain the best possible estimate.

i.Labor lawsuits

These are lawsuits aimed at obtaining compensation for labor-related claims. The provisioned amounts mostly refer 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 cases finalized and the amount actually disbursed in the last 36 months.


			Notes to the interim condensed consolidated financial statement As of September 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 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 September 30, 2026, the amount at risk from the lawsuit totals R$31,075 (December 31, 2025: R$32,147), while the total amount of the lawsuit corresponds to R$70,114 (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 September 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 September 30, 2026, the value at risk of the action totals R$78,030 (December 31, 2025: R$73,000), while the total value of the action corresponds to R$177,156 (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 options to purchase Banco Inter S.A. shares were granted to Inter's directors and executives.

On January 4, 2023, an Extraordinary General Meeting of Inter&Co, Inc. was held, in which the migration of the share-based payment plans was approved, with Inter&Co assuming 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 changed proportionally. Thus, for every 6 options to purchase common or preferred shares of Banco Inter S.A., the beneficiary will have one option to purchase a Class A Share of Inter&Co. In addition, the repricing of the exercise price of the options granted in 2022, which had not yet been exercised, was approved. Upon repricing, a new calculation of the fair value of the granted and unexercised options was performed, resulting in an additional incremental expense of R$ 15,990, to be appropriated until the final vesting period.

The main characteristics of the plans are described below:

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 compensation to the acquired entity's key executives would be made through the migration of Inter&Co Payments, Inc.'s stock-based compensation plan, with an addendum providing that the stock purchase option could be exercised on Inter&Co's Class A shares and/or Inter&Co's restricted Class A shares, as applicable, instead of Inter&Co Payments, Inc.'s shares. Considering the characteristics of the contract signed between the parties, the expenses associated with the granted options were treated as compensation expense accounted for over the term of the exercisable options and based on the continued employment of such key executives.

All put options that had been granted were exercised, with the last tranche being exercised on January 7, 2025.

All stock purchase options granted under the Inter&Co Payments, Inc. share-based payment plan, migrated to Inter&Co, have been exercised and the shares have been fully transferred to the eligible key executives as of October 31, 2025, totaling 489,386 shares.

Due to the completion of the aforementioned transactions, the share-based payment plan of Inter&Co Payments, Inc., has been terminated and discontinued.

36.Other information

Consumer Tax Reform

Complementary Laws No. 214/2025 and No. 227/2026, enacted within the scope of the Consumption Tax Reform, established the Tax on Goods and Services (IBS), the Contribution on Goods and Services (CBS), and created the IBS Management Committee, as well as establishing the general rules for administration, oversight, collection, and distribution of revenue from the new taxes. The IBS and CBS will gradually replace the following taxes: PIS/Pasep, COFINS, ISS, IOF-Insurance, ICMS, and IPI, which will be discontinued throughout the implementation period of the Tax Reform.

The regulation also defined the IBS and CBS rates applicable to financial services for the transition period between 2027 and 2033, with a progressive increase in the tax burden from 10.85% to 12.50%. Conversely, for operations currently subject to ISS, a gradual reduction in the rate from 2% to 1.2% is foreseen over the same period of migration to the new tax regime.

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.
