Consolidated Financial Statements - 1st Quarter 2026

BB Seguridade Participações S.A.

We present the Financial Statement of BB Seguridade Participações S.A ("BB Seguridade") for the first quarter of 2026, in accordance with the International Financial Reporting Standards (IFRS) and the rules of the Accounting Pronouncements Committee (CPC), including the IFRS 17.

In 1Q26, BB Seguridade reported net income of R$2,139.4 million, representing an 8.9% increase compared to the same period of 2025. The main drivers behind the R$175.2 million increase in net income were:

• Brasilprev (+R$102.2 million): attributed to the improvement in the insurance margin, primarily concentrated in the variation of the loss component of traditional plans compared to 1Q25. This performance was impacted by: i) higher financial surplus expenses in 1Q25, considering asset returns exceeding the remuneration rate of interest-bearing liabilities. It is worth noting, however, that this effect was reversed in 2Q25 following a revision of the cash flow projection model; and ii) change, as of 1Q26, in the accounting treatment of IGP-M deviation compared to the transition "locked-in" rate, which ceased to affect the loss component line and started to be recognized under financial expenses;

• Brasilcap (+R$33.8 million): with the rise in net investment income, supported by the expansion of the average balance of financial assets and improved financial margin;

• BB Corretora (+R$26.4 million): sustained by the increase in net margin, due to higher net investment income and brokerage revenues growth;

• Holdings (+R$11.3 million): improvement primarily driven by a stronger financial result from BB Seguros;

Brasilseg's contribution to net income fell R$7.7 million YoY. This performance was mainly driven by a decline in net investment income, influenced by: (i) higher monetary adjustment on claims, reflecting the increase in the average Selic rate and the expansion of the average balance of provisions for judicial pending claims ("PSLJ"), combined with a contraction in the average balance of interest-earning assets, which negatively impacted the growth of interest revenues; and (ii) the reversal of R$19.7 million in provisions for judicial pending claims recognized in 1Q25, as a result of changes in monetary adjustment and interest rates (Law No. 14,905/2024). However, part of this effect was offset by the growth in insurance and reinsurance margins, supported by an improvement in the loss ratio compared to 1Q25.

In 1Q26, the holding's other income and expenses recorded a negative balance R$1.8 million higher than the reported in the same period of 2025 (+34.3%), largely explained by the growth in tax expenses levied on financial income.

Net investment income was up R$18.3 million, reflecting the expansion in the average balance of financial investments and the higher Selic rate.

      The individual financial statements have been prepared in accordance with the accounting guidelines derived from Brazilian corporation law and are presented in compliance with accounting practices adopted in Brazil (BRGAAP), ncluding in accordance with CPC 21 (R1) - Interim Financial Statements, which include the guidelines issued by the Corporations Law and the pronouncements of the Comitê de Pronunciamentos Contábeis - CPC (Accounting Pronouncements Committee), approved by Comissão de Valores Mobiliários - CVM (Securities Commission).

      All the relevant information specific to the financial statements are evidenced and correspond to those used by the Company's Management.

      These financial statements were approved and authorized by BB Seguridade's Board of Directors on April 30, 2026.

   2. Continuity

      Management evaluated the capacity of BB Seguridade to continue normally operating and it is convinced that it has the resources to continue its business in the future. In addition, Management is not aware of any material uncertainties that could generate significant doubts about its ability to continue operating, Accordingly, these consolidated and individual financial statements were prepared based on the assumption of operating continuity.

   3. Measurement Basis of Assets and Liabilities

      These individual and consolidated financial statements were prepared using historical cost as a measurement basis, except when otherwise indicated.

   4. Functional and Presentation Currency

      BB Seguridade's financial statements are presented in Reais, which is the functional currency. Unless otherwise indicated, quantitative financial information is presented in thousands of Reais (R$ thousand).

   5. Consolidation Basis

      The consolidated financial statements of the BB Seguridade and subsidiaries are included the consolidation of assets and liabilities from BB Seguridade and its controlled entities, as follows:

      Company	Activity	Country of constitution	% Share Mar 31, 2026	Dec 31, 2025
      BB Seguros Participações S.A.	Holding	Brazil	100%	100%
      BB Corretora de Seguros e Administradora de Bens S.A.	Brokerage	Brazil	100%	100%

      The intra-group balances and transactions, such as any unrealized income or expenses on transactions between companies of the consolidated, are eliminated in preparing the consolidated financial statements.

   6. Seasonality of Operations

      BB Seguridade and its owned subsidiaries consider the nature of their transactions as non-seasonal and non-cyclical, taking into account the activities carried out by the Group. Consequently, no specific disclosures are provided in these notes.

   7. Main Judgments and Accouting Estimates

      The preparation of financial statements in accordance with accounting practices adopted in Brazil and IFRS requires Management to make judgments and estimates that affect the recognized values of assets, liabilities, revenues and expenses. The estimates and assumptions adopted are analyzed on an ongoing basis, with any revisions made recognized in the year in which the estimate is reevaluated, with prospective effects. It should be noted that the results achieved may be significantly different from current estimates.

      Considering that, in many situations, there are alternatives to accounting treatment, the results disclosed could be different if a different treatment was chosen. Management considers that the choices are appropriate and that the financial statements adequately present the financial position of BB Seguridade, the results of its operations and its cash flows, individual and consolidated, in all materially relevant aspects.

      Significant assets and liabilities subject to these estimates and assumptions include items such as fair value of financial instruments, impairment of financial and non-financial assets, recognition and measurement of deferred taxes and provisions, and contingent liabilities.

3. ‌- MATERIAL ACCOUNTING POLICIES

   Accounting practices are the principles, bases, conventions and specific rules applied by BB Seguridade in the preparation and presentation of financial. BB Seguridade applied accounting policies consistently to all periods presented in these interim financial statements.

   1. Revenue and Expense Recognition

      Revenues and expenses are recognized on an accrual basis and are reported in the financial statements for the periods to which they refer. Revenues are increases in assets, or decreases in liabilities, resulting in increases in the shareholders' equity, except for those referring to contributions from holders of rights on the equity.

      This concept is applied to the main revenues arising from the activities of BB Seguridade and its investees, namely:

      1. Revenue from investments in shareholdings - Revenue from the application of the equity method for assessment of the investments in shareholdings are recognized in proportion to the BB Seguridade's equity on the investees' income, according to the CPC 18 (R2) [IAS 28] - Investments in Associates and Joint Ventures.

      2. Revenue from commissions - Revenue from commissions are recognized pro rata when its value, its related costs and the conclusion stage of the transaction can be measured reliably and when its related economic benefits are likely to be effective, according to the CPC 47 [IFRS 15] - Revenue from Contracts with Customers.

         To recognize its revenue, BB Corretora uses a five-stage model concept to determine when to recognize the revenue: i) identification of the contract; ii) identification of the performance obligations; iii) determination of the price for the transaction;

         iv) allocation of the price for the transaction and v) recognition of revenue.

         Revenues from commissions are recognized when the Company meets (or as the Company meets) its performance obligation when transferring the goods and services (in other words, assets) in agreement with a client. Revenues from commissions arise from the segments of people insurance, casualty insurance, pension plans, capitalization and health insurance. These revenues are recognized over time (products with established validity), where the performance obligation is diluted linearly over the lifetime of the product/insurance, or at a specific time (monthly products), where the performance obligation is due monthly, according to the characteristics of the products.

         In cases of return of the Premium to the insured parties, the broker reimburses, to the insurer, the commission received in proportion to the value refunded in relation to the remaining period of the policy.

         For insurance whose expiry date is not objectively established (monthly insurance), monthly payment of premiums is decisive for the continuity of the policies, and, in general, there are no refunds of the commissions.

         For pension plans, amounts arising from cancellations are recognized and returned monthly. Additionally, a provision is set up for the return of brokerage fees, estimated for future cancellations in the 12 months following the date of sale, recognized in Current Liabilities (Other Liabilities).

      3. Financial revenues and expenses - Revenues and expenses from financial instruments arising from assets and liabilities that generate and pay for monetary correction and/or interest, as well as the values related to the correction of the fair value, are recognized in the income for the fiscal year on an accrual basis, using the effective interest rate method, according to the CPC 48 [IFRS 9] - Financial Instruments.

         In the case of instruments measured at fair value through income (in accordance with item c.3 below), the fair value is determined as described in item c.4.

   2. Cash and cash equivalents

      Cash and cash equivalents are represented by the cash available in national currency and investments in committed operations, with high liquidity and insignificant risk of change in value, with maturity equal to or less than 90 days.

   3. Financial instruments

      The financial instruments are classified in relation to the business model and the contractual characteristics of the cash flows of the instruments according to the CPC 48 [IFRS 9] - Financial Instruments.

      Financial instruments are initially measured at fair value plus the transaction cost, except when financial assets and liabilities are recorded at fair value through the income.

      Financial assets and liabilities can be classified into one of the categories: i) financial instrument measured at fair value through the income, ii) financial instrument measured at amortized cost and iii) financial instrument measured at fair value through other comprehensive income.

      The main financial instruments of BB Seguridade and its subsidiaries are securities held in custody at Banco do Brasil (government securities and repurchase agreements backed by federal government securities). During this period, there was no use of derivative instruments by the Group.

      For health plan operators, ANS adopted CPC 48 (IFRS 9) - Financial Instruments for periods starting in 2023. For insurance companies, SUSEP adopted the standard for periods starting in 2024.

      1. Amortized Cost - This category includes financial assets held (i) for the purpose of receiving its contractual cash flow rather than for sale with realization of profits or losses and (ii) whose contractual terms generate cash flows at specified dates exclusively for principal payments and interest payments on the outstanding principal value.

         Commissions receivable and LFTs - Financial Treasury Bills are recognized as financial assets measured at amortized cost.

      2. Fair value through other comprehensive income - VJORA - This category includes financial assets held (i) both for the receipt of its contractual cash flow and for sale with realization of profits or losses and (ii) whose contractual terms generate cash flows at specified dates exclusively for principal payments and interest payments on the outstanding principal value.

         For the period, the Group did not have financial assets classified in this category.

      3. Fair value through profit or loss (VJR) - Financial assets that are not measured at amortized cost or at fair value through other comprehensive income are classified in this category.

         Repurchase agreements are recognized as financial assets measured at fair value through profit or loss.

      4. Determination of fair value - Fair value is the price that would be received for the sale of an asset or would be paid by the transfer of a liability in a non-forced transaction between market participants at the measurement date.

         The fair value of financial instruments traded in active markets on the base date of the balance sheet is based on the quoted market price or on the quotation of the over-the-counter price (selling price for purchased positions or purchasing price for sold positions), without any deduction of transaction cost.

         In situations where there is no market price for a particular financial instrument, its fair value is estimated based on valuation methods commonly used in the financial markets, which are appropriate to the specific characteristics of the instrument and capture the various risks to which it is exposed. The valuation methods include: the discounted cash flow method, comparison to similar financial instruments for which there is a market with observable prices, option pricing models, credit models and other well-known valuation models.

         The internal pricing models may involve some level of estimation and judgment by the Administration, whose intensity will depend, among other factors, on the complexity of the financial instrument.

      5. Financial liabilities - An instrument is classified as a financial liability when there is a contractual obligation, of which its settlement is made through the delivery of money or other financial asset, regardless of its legal form. Financial liabilities include short-term and long-term debt that are initially measured at fair value, which is the net value received of costs levied upon the transaction and, subsequently, upon the amortized cost.

   4. Write-off of Financial Assets and Financial Liabilities

      1. Financial assets - A financial asset is written off when: (i) the contractual rights related to the respective cash flows expire; (ii) most of the risks and benefits associated with the asset is transferred to third parties; or (iii) when control over the asset is transferred, even if part of the risks and benefits associated with its holding is retained.

      2. Financial liabilities - A financial liability is written off when its obligation is eliminated, canceled or expired. If an existing financial liability is replaced by another from the same creditor in substantially different terms, or the terms of the existing liability are substantially modified, such modification is treated as a write-off of the original liability and as the recognition of a new liability, and the difference between the book values is recognized in the income.

   5. Reduction in the Recoverable Value of Financial Assets - Impairment

      For the recoverable value of financial assets (impairment), the CPC 48 [IFRS 9] - Financial Instruments considers the expected credit losses, which are a weighted estimate of the probability of credit losses (that is, the present value of all cash deficits) over the expected life of the financial instrument.

      Cash deficit is the difference between the cash flows due to the entity according to the contract and the cash flows that the entity expects to receive. As the expected credit losses consider the value and timing of the payments, the credit loss occurs even if the entity expects to be paid in full, but after the due date stipulated by the contract.

      For the impairment of commissions receivable, the simplified approach allowed by the CPC 48 [IFRS 9] for commercial receivables was used, in which the recognition of expected credit losses follows the model for the entire life of the instrument.

      These trade receivables arising from commissions receivable are assessed as having a low credit risk under IFRS 9, given the nature of the underlying transactions. This assessment reflects the fact that substantially all brokerage revenues originate from operations conducted with entities within the Group, for which the financial settlement process is predominantly executed through Banco do Brasil's systems.

      Annually or whenever there is an indication that the financial asset may be devalued, an assessment to check if there is any objective evidence of impairment of its financial assets is carried out at BB Seguridade, in accordance with the CPC 48 [IFRS 9] - Financial Instruments.

      During the period, there were no losses due to devaluation of BB Seguridade Group's financial assets.

   6. Share Premium and Other Intangible Assets

      The share premium generated on the acquisition of investments on shareholdings is accounted for considering the fair value assessment of the identifiable assets and the assumed liabilities of the acquired company on the acquisition date and, in accordance with the applicable standards, is not amortized. However, it is tested, at least annually, for impairment purposes. After the initial recognition, the share premium is measured at cost minus any accrued impairment losses.

      Intangible assets are separately recognized from the share premium when they are separable or arise from contractual rights or other legal rights, their fair value can be measured reliably, and it is probable that the expected future economic benefits will be transferred to BB Seguridade. The cost of intangible assets acquired in a business combination is its fair value at the acquisition date. The other acquired intangible assets, not linked to the business combination, are initially measured at cost.

      The useful lives of intangible assets is definite or indefinite. Intangible assets with defined useful lives are amortized over the course of their economic life. They are initially registered at cost, minus the accrued amortization and impairment losses. Intangible assets with indefinite useful lives are recorded at cost minus any impairment losses.

      The period and method for the amortization of intangible assets with definite useful lives are reviewed, at a minimum, annually. Changes in the expected useful life or proportion of expected use of the future benefits incorporated to the asset are recognized through changes in the period or method for the amortization, when appropriate, and treated as changes in accounting estimates.

      The costs incurred related to the acquisition, production and development of software are capitalized and registered as intangible assets. Expenditures from the research phase are registered as expenses.

      The expense with the amortization of intangible assets with definite useful life and impairment losses are recognized in the income for the year in the line "Other" of the Income Statement.

   7. Reduction in the Recoverable Value of Non-Financial Assets - Impairment

      Annually or whenever there is an indication that the asset may be devalued, an assessment, based on internal and external sources of information, to check if there is any indication that a non-financial asset may be with recoverability problems is carried out. If there is such an indication, the asset's recoverable value is estimated. The recoverable value of the asset is the highest between its fair value minus the costs to sell it or its value in use.

      Whether there was any indication of reduction in the recoverable value, the impairment test of an intangible asset with indefinite useful life is annually carried out, including the share premium acquired in a business combination, or an intangible asset not yet available for use. This test can be carried out at any time during an annual period, provided it is performed at the same time each year.

      If the recoverable value of the asset is lower than its book value, the book value of the asset is reduced to its recoverable value through recording an impairment loss, for which the consideration is recognized in the income statement for the period in which it occurs, in other Operating Expenses/Revenues.

      Annually, it is further assessed if there is any indication that a loss by impairment recognized in previous fiscal years for an asset other than the share premium for expected future profitability, might no longer exist or may have been reduced. If there is such indication, the recoverable value of this asset is estimated. The reversal of a loss by impairment of an asset will be immediately recognized in the income for the fiscal year, as a rectifier of the balance of other Operating Expenses/Revenues.

      During the period, there were no losses due to the devaluation of non-financial assets of the BB Seguridade Group.

   8. Investments in Associates

      Under the equity method, the investment is initially measured at cost and subsequently adjusted by the investor's recognition of changes in the net assets of the investee. In addition, the portion of the investor's income in the profits and losses generated by the investee must be included in the income for the fiscal year of the investor, according to the CPC 18 (R2) [IAS 28] -Investments in Associates and Joint Ventures.

      Investments in equity interests in the companies BB Seguros Participações S.A. and BB Corretora de Seguros e Administradora de Bens S.A. are classified as investments in subsidiaries and valued using the equity method and are consolidated.

      Investments in equity interests in the companies BB MAPFRE Participações S.A., Brasilprev Seguros e Previdência S.A., Brasilcap Capitalização S.A., Brasildental Operadora de Planos Odontológicos S.A. and Ciclic Corretora de Seguros S.A. are valued using the equity method, whether classified as investments in associates or joint ventures.

      In accordance with CPC 18 [IAS 28], the equity value of investees, for purposes of applying the equity method, will be recognized based on the balance sheet or verification balance prepared, on the same date, or within two months of lag. Due to operational issues the accounting recognition of the investment in Brasildental, through the equity method, is being carried out with a delay of one month. For the other companies, the dates coincide with the accounting closing date of the BB Seguridade Group.

      In situations where the investees use different accounting practices in events and transactions of the same nature in similar circumstances, the necessary adjustments are carried out to make the financial statements of the investees suitable to the accounting practices adopted by the investor.

   9. Provisions and Contingent Liabilities

      The recognition, measurement and disclosure of contingent liabilities and legal obligations are carried out in accordance with the criteria defined in the CPC 25 [IAS 37] - Provisions Contingent Liabilities and Contingent Assets.

      Provisions related to legal and administrative proceedings are recognized in the financial statements when, based on the analysis of legal advisors and the Management, the risk of loss of a legal or administrative action is deemed probable, with a probable outflow of funds for the settlement of obligations and when the amounts involved are measurable with sufficient certainty.

      Contingent liabilities classified as possible losses are not recognized in accounting and are only disclosed in the explanatory notes, and those classified as remote do not require provision and disclosure.

   10. Taxes

       Taxes are calculated based on the rates shown in the table below:

       Taxes	March 31, 2026	Dec 31, 2025
       Individual Income Tax (IRPJ) (¹)	25%	25%
       Social Contribution on Net Income (CSLL)	9%	9%
       Contribution to PIS (Social Integration Program) / Pasep (Investment Program for Civil Servants)	1.65%	1.65%
       Contribution to the Financing of Social Security (COFINS)	7.60%	7.60%
       Contribution to PIS / Pasep on income from financial investments	0.65%	0.65%
       Contribution to the Financing of the Social Security (COFINS) on income from financial investments	4%	4%
       Service Tax - ISS (2)	Up to 5%	Up to 5%

       1. Includes basic (15%) and additional (10%) rates

       2. Incident on the services provided by BB Corretora.

       The deferred tax assets and deferred tax liabilities are constituted by the application of the current tax rates on their respective bases. For constitution, maintenance and write-off of deferred tax assets, the criteria established by the CPC 32 [IAS 12] -Income Taxes are observed, and they are supported by a realization capacity study.

       Tax reform

       In December 2023, Constitutional Amendment 132/2023, also known as Consumption Tax Reform, was approved, which substantially changes the current form of taxation of goods and services, replacing current indirect taxes with the Tax on Added Value (VAT) in dual mode, comprising the Contribution on Goods and Services (CBS) and the Tax on Goods and

       Services (IBS), in addition to the creation of a selective tax (IS). Through the Amendment, the general guidelines of the national tax system were defined.

       On 01/16/2025, Complementary Law 214/2025 (Complementary Bill 68/2024) was sanctioned, the first act that regulates the consumption tax reform provided for in Constitutional Amendment 132/2023, thus creating the Tax on Goods and Services (IBS), the Social Contribution on Goods and Services (CBS) and the Selective Tax (IS).

       On January 13, 2026, Complementary Law 227/2026 (originating from Complementary Bill 108/2024) was enacted, establishing the Managing Committee of the Goods and Services Tax (CGIBS) and setting forth the administrative tax procedures related to IBS, among other provisions. Following its enactment, the regulatory framework and the implementation of the test phase for the new tax are expected to advance throughout 2026.

       The Complementary Law 227/2026, through an amendment to Complementary Law 214/2025, established that the combined rates of IBS and CBS applicable to companies classified under the Specific Regime for Financial Services will total 10.85% in 2027 and 2028, with a gradual increase from 2029 through 2033, reaching 12.50%. No rate has yet been defined for the General Regime.

       BB Seguridade and BB Seguros are classified under the General Regime. BB Corretora and the investee companies Brasilseg, Aliança do Brasil Seguros, Brasilprev and Brasilcap are classified under the Specific Regime for Financial Services.

       As the current stage of the tax reform still depends on further rulemaking and regulatory guidance, it is not possible to estimate its impact at this time. The Company continues to monitor developments and to implement systemic and operational measures aimed at adapting to the new regulations.

   11. Segment Disclosure

       The CPC 22 [IFRS 8] - Operating Segments requires the disclosure of financial information of the entity's operating segments based on the internal disclosures that are used by the Management to allocate resources and to assess its financial and economic performance.

   12. Interest in Net Equity and Dividends

       Brazilian companies may assign a nominal interest expense, deductible for tax purposes, on their net equity. The value of the interest on the net equity is considered as a dividend and, when applicable, presented in these consolidated financial statements as a direct reduction in the stockholders' equity.

       Under the current dividends policy, BB Seguridade distributes to shareholders, as mandatory dividends, a portion corresponding to at least 25% of the adjusted net profit with the deductions and increases provided for in Art. 202 of Law 6.404/76, which are recognized as a liability and deducted from the shareholders' equity when allocating the income for the year.

       During the period, there was no recognition and payment of interest on shareholders' equity by BB Seguridade.

   13. Earning per share

       The disclosure of the earnings per share is made in accordance with the criteria defined in the CPC 41 [IAS 33] - Earnings per Share - approved by the CVM Resolution 636/2010. The basic and diluted earnings per share of BB Seguridade were calculated by dividing the net profit attributable to the shareholders by the weighted average number of total common shares, excluding treasury shares. BB Seguridade has no optional instruments, subscription bonus or their equivalents that provide its holder the right to acquire shares. Thus, basic and diluted earnings per share are equivalent.

   14. Leases

       The recognition, measurement and disclosure of leases are carried out in accordance with the criteria defined in the CPC 06 (R2) [IFRS 16] - Leases.

       Leasing operations are present in insurance companies and health operators, in which BB Seguridade holds shares, through its subsidiary BB Seguros.

   15. Insurance Contracts

       Recognition, measurement and disclosure of insurance contracts are carried out in accordance with the criteria defined in CPC 50 [IFRS 17] - Insurance Contracts. The insurance contract is defined by CPC 50 [IFRS 17] as an agreement between the insurer and the insured, in which the insurer accepts the risk of a possible financial loss or other adverse event that may affect the insured. In return, the policyholder pays a premium to the insurer.

       The operational investees that commercialize insurance contracts apply the insurance contract grouping levels, by harvest, portfolio, groups and harvest.

       The portfolios were determined by first identifying contracts subject to similar risks and managed together, in pension plans: Traditional, PGBL/VGBL, Conjugated VGBL, Risk Coverage and Reinsurance; and in insurance: annual risk and multi-year risk.

       The portfolio groups are divided into onerous and non-onerous contracts, the latter having no significant possibility of becoming onerous after initial recognition and other contracts remaining in the portfolio.

       Furthermore, the contracts of each group are segregated into harvests, with periods of up to one year between the start dates (annual cuts). Reinsurance contracts are established so that each group contains a single contract.

       According to the characteristics of insurance contracts, the application of accounting models is divided into:

       • BBA - Building Block Approach (General Measurement Model): standard model for all insurance contracts based on future cash flow estimates segregated into three main components: i) Contractual Service Margin (CSM), which represents the profit that the insurer expects to generate with insurance contracts over time, to be realized over the term of the contract; ii) Present value of future cash flows, which represents the estimate of cash flows that the insurer expects to receive and pay in the future, adjusted for the time value of money and ; iii) Non-financial risk adjustments which are estimates of risks associated with insurance contracts that cannot be measured using the time value of money, including risks related to events such as mortality, morbidity, claims and expenses. This measurement model includes the portfolios of lending insurance and housing insurance; and the Traditional pension products, VGBL Conjugated and Risk Coverage, as well as their Reinsurance operations.

       • PAA - Premium Allocation Approach: optional simplified model, indicated for short-term insurance contracts (coverage up to one year) or when the remaining coverage is not materially different from the value calculated in the BBA model. This model includes all insurance contracts with a duration equal to or less than one year, both life and non-life, and those contracts with a duration of up to 5 years whose valuation results would not differ significantly in relation to the general BBA model.

       • VFA - Variable Fee Approach: model for treating insurance contracts with underlying return components. It follows the same general measurement model (BBA), with the difference being a variable remuneration component in its compliance flows. The VFA modifies the treatment of the CSM in subsequent measurement to include contracts where the insured participates in a substantial part of the returns of underlying items, such as an asset portfolio. This model includes PGBL and VGBL pension products.

       When recognizing the BBA model, it is necessary to consider future cash flow estimates, as well as adjustments to present value and upon initial recognition by the non-financial risks, to assess whether insurance contracts are in surplus or in deficit. If the future cash flow is positive, the contractual service margin is recognized in liabilities and is converted into revenue over the term of the insurance contracts. However, if the cash flow is negative, insurance contracts are considered onerous, as they have a deficit contractual service margin, and the amounts must be accounted for immediately in income.

       In the PAA model, based on the remaining coverage liability, like the current methodology of unearned premiums, liability amounts are recognized in income according to the period of effectiveness of the insurance contracts.

       Estimates are part of the accounting recognition and measurement process, since uncertainty is an inherent characteristic of insurance contracts. According to CPC 23 [IAS 8] - Accounting Policies, Changes in Accounting Estimates and Errors, accounting estimates may require revision as the facts and/or circumstances in which they were made change, increase the level of experience and additional information becomes available. The effect of changing estimates must be recognized prospectively.

       The estimates are periodically reviewed by the operational investees with the objective of verifying their adherence to the operations based on the greater experience verified with the behavior of the insurance contracts.

       The individual companies BB Seguridade, BB Seguros and BB Corretora do not have operations that are within the scope of the insurance contract rule. However, the operating investees that sell insurance contracts - Brasilseg and Aliança do Brasil Seguros, controlled by the holding company BB MAPFRE, Brasilprev and Brasildental - are affected by the accounting rules.

       Brasilcap's products are not within the scope of CPC 50 [IFRS 17] and the impacts related to CPC 48 [IFRS 9] have already been recognized at BB Seguridade since 2018, through the harmonization of accounting practices.

       The respective impacts on investee companies are presented in Note 07 - Investment.

   16. Harmonization of accounting practices of CPC 50 [IFRS 17]

       Although CPC 50 [IFRS 17] has not yet been approved by SUSEP and ANS, the respective operational investees of BB Seguridade that sell insurance contracts within the scope of the standard must prepare their financial statements in the new standard, to comply with the accounting standards applicable to BB Seguridade.

       In this sense, at the initial moment of adoption, the impacts on shareholders' equity and investments in equity interests were reflected in the financial statements of BB Seguridade and, later, the subsequent impacts through equity equivalence.

       Despite the initial adoption of accounting standard by the operational investees that sell insurance contracts, in which the accounting effects occur through the harmonization of accounting practices, insurance companies and health plan operators are not yet adopting these standards and, therefore, there will be no impacts for the effects of regulatory requirements, determined by SUSEP and ANS.

       Likewise, considering that the regulatory and corporate rules for insurance companies and health plan operators will not be affected by the accounting standard, no impacts are expected on the distribution of dividends or on the capital management of such companies arising from the harmonization of their accounting practices to those of BB Seguridade and BB Seguros.

   17. Standards recently issued, applicable or to be applied in future periods

       CPC 51 - Presentation and Disclosure in Financial Statements [IFRS 18] - The new accounting standard was issued by the Brazilian Accounting Pronouncements Committee (CPC) on October 10, 2025, and approved by the Federal Accounting Council (CFC) through NBC TG 51 on November 13, 2025, as well as by the Brazilian Securities and Exchange Commission (CVM) through CVM Resolution No. 237 dated December 23, 2025. The standard is aligned with IFRS 18 - Presentation and Disclosure in Financial Statements and will replace CPC 26 (R1) - Presentation of Financial Statements. Adoption of the new standard is scheduled for January 1, 2027.

       The objective of the new standard is to enhance the communication of information in financial statements, with a particular emphasis on corporate performance-namely, the statement of profit or loss and the related notes.

       The main change concerns the presentation structure of the Statement of Profit or Loss, which will now segregate results into Operating, Investing, and Financing categories, in accordance with each entity's business model. In this regard, the standard aims to increase comparability, provide greater transparency to management-defined performance measures, and promote more meaningful grouping of financial information.

       The impacts of adopting the new requirements are currently being evaluated by the Company.

       IFRS S1 - General requirements for disclosure of sustainability-related financial information and IFRS S2 - Climate-related disclosures - In June 2023, the International Sustainability Standards Board (ISSB) issued the first two sustainability reporting standards, with the aim of developing and issue a comprehensive global framework of sustainability reporting standards. IFRS S1 and IFRS S2 require the entity to disclose information about risks and opportunities related to sustainability and climate. IFRS S1 covers general requirements for reporting sustainability information, while IFRS S2 focuses on specific climate disclosures.

       In Brazil, the Comitê Brasileiro de Pronunciamentos de Sustentabilidade (CBPS) promotes the adoption of these standards, standardizing reports and facilitating the analysis of organizations' financial performance and future strategy in relation to sustainability. In October 2023, the Comissão de Valores Mobiliários (CVM) published CVM Resolution No. 193, which provides for the preparation and disclosure of financial information reports related to sustainability, based on the international standard issued by the ISSB.

       On October 29, 2024, the CBPS released Pronouncement CBPS 01 - General Requirements for Disclosure of Financial Information Related to Sustainability and Pronouncement CBPS 02 - Climate-Related Disclosures, both approved by the Federal Accounting Council (CFC) through NBC TDS 01 and NBC TDS 02, respectively. The standards were also approved by CVM, on the same date, through CVM Resolutions 217 and 218.

       Publicly held companies may adopt disclosure, on a voluntary basis, for the report relating to the 2024 financial year. From the 2026 fiscal year onwards, the report becomes mandatory for publicly held companies, together with the annual financial statements. Sustainability financial statements must be presented in a consolidated form and separated from the financial statements.

       The impacts of adopting the new regulations are being assessed by the BB Seguridade Group.

4. ‌- ACQUISITIONS, DISPOSALS AND CORPORATE RESTRUCTURINGS ‌Broto S.A.

   Broto S.A. ("Broto" or "Company"), a company established on January 4, 2023, to conduct the business of the Broto Digital Platform, has as shareholders Brasilseg Companhia de Seguros ("Brasilseg") and Banco do Brasil S.A. ("Banco do Brasil").

   As provided for in the corporate agreements, Brasilseg maintains access to the Broto Digital Platform to sell its insurance products, which is exclusively brokered by BB Corretora de Seguros e Administradora de Bens S.A., a company controlled by BB Seguridade.

   The corporate documents establish a purchase option granted to Banco do Brasil - not yet exercised - by Brasilseg, on all of its shares in Broto, exercisable upon payment of the full amount contributed by it to Broto, adjusted by the CDI accumulated in the period, within a period of up to 12 months, counted from the date of execution of the Shareholders' Agreement, extendable for the same period. Upon formalization of the Third Extension Term signed between the parties on December 30, 2025, the term for exercising the purchase option was extended until January 4, 2028.

   On March 6, 2026, at the General Meeting of Broto, an increase in the Company's share capital was approved, totaling R$ 18,000,000.00, through the issuance of 18,000,000 registered shares without par value, at an issue price of R$ 1.00 per share, consisting of 9,000,000 common shares and 9,000,000 preferred shares without voting rights, with the advantages and characteristics described in the Company's Bylaws, which were fully subscribed and paid up by the shareholders Banco do Brasil and Brasilseg, in proportion to their original shareholdings in the share capital. Thus, Banco do Brasil paid R$ 9,000,000.00 and Brasilseg paid the other R$ 9,000,000.00, without any involvement of funds from BB Seguridade or BB Seguros.

   After full payment, Broto's share capital was R$ 137,400,000.00, represented by 137,400,000 registered shares with no par value, of which 68,700,000 are common shares and 68,700,000 are preferred shares without voting rights, distributed among the shareholders in the following proportion:

5. - RISK MANAGEMENT

   ‌The risk management at BB Seguridade follows the guidelines established in its Capital and Risk Management Policy,

   approved by the Board of Directors, and disclosed to the market through the investors' relations website.

   The Company understands that its risk exposure originates from its interests, and therefore the Capital, Risk, Internal Controls and Compliance Management Policy contemplate two risk management dimensions: risk management (risks arising from the operations of BB Seguridade and its subsidiaries) and risk governance (risks arising from associates/joint ventures).

   By means of its Risk Appetite Statement, approved by the Board of Directors, the Company defines the maximum levels of risks that it accepts to incur in the fulfillment of its objectives.

   The risk management process at BB Seguridade is based on the international framework of ISO 31000:2018 and comprises the steps of setting the context, identifying, analysis, evaluating and treating risks. Transversal to each step of risk management, there are consultations with interested parties, monitoring, and critical analysis, which help in continuous improvement. This process is internally documented in the Group's Risk Management, Internal Controls and Compliance Model.

   BB Seguridade's risk management is integrated into the corporate strategy, from the preparation of planning, as well as during the execution of the strategy, scenario analysis and decision-making support at all levels of the Company.

   The Company has the Superintendence of Risk Management and Capital and the Superintendence of Internal Controls Management and Integrity. The first is responsible for providing fundamentals and support for the execution of the risk management process; the second is responsible for internal controls, compliance, and the Integrity Program. Both also act in the governance of risks and controls, respectively, in the companies in which BB Seguridade holds interests. For this to work properly, the areas are segregated from the business and Internal Audit areas.

   1. Risk management at BB Seguridade and its subsidiaries

      The risk management framework adopted by BB Seguridade, as defined in its Risk Management, Internal Control and Compliance Policy, is structured based on a three-line model: in the first line, the process managers (risk owners) are responsible for implementing preventive and corrective actions that mitigate the weaknesses identified in the processes and control deficiencies; in the second line, the Superintendence of Risk Management and Capital and the Superintendence of Internal Controls Management and Integrity assist and monitor the risk owner in managing risks and internal controls in order to adjust them to the Group's risk appetite; and in the third line, the Internal Audit works independently, by providing to governance bodies assessments on the risk management and internal control effectiveness.

      The risk management mechanisms and tools also include, among others: segregation of duties; joint decisions; Information Security and Cybernetics Policy, Preventing and Combating Money Laundering and Terrorist Financing Policy, in line with Circular Susep 612/2020 and subsequent amendments; Preventing and Combating Corruption Policy, Code of Ethics and Conduct and an Integrity Program in line with Law 12,846/2013 (Anti-Corruption Law) and the Decree 11,129/2022 (documents disclosed internally and also to the market, available at the investors relations website); internal risk management, internal controls and compliance regulations, in addition to internal communication program on risk management, internal controls and compliance, continuously promoting the adaptation of the entire Group to these subjects.

      The Executive Board is supported by the Continuity and Crisis Management Committee, which advises on the assessment and mitigation of risks of discontinuity, incidents, or crises.

      BB Seguridade's governance structure also comprises the Risk and Capital Committee, a statutory agency to advise the Board of Directors, which is responsible, among other things, for assessing and monitoring the Group's risk exposures.

      The Audit Committee, a statutory agency, is responsible, among other things, for sharing, with the Board of Directors, the risks, weaknesses, or concerns that may have a significant impact on the Company's financial conditions and business.

      Information related to risk management and internal controls is periodically reported to the Collegiate Board of Directors, the Administrative Council, and the Fiscal Council.

      1. Risks associated with investments in financial assets

         The Group has a Financial Investment Policy, approved by the Board of Directors and applicable to all companies of the Group, that sets out the criteria relating to the nature, term, and acceptable risks of the financial investments. The current policy allows the investment only in federal government bonds, repurchase agreement guaranteed by federal government bonds and extra-market investment funds.

         The investments in financial assets of BB Seguridade and its subsidiaries, classified as cash equivalents, are concentrated on repurchase agreements backed by Federal Government Bonds (Note 15). Other investments in financial assets classified as financial instruments are invested in fixed-income long-term mutual fund and federal government bonds (Note 16).

      2. Market Risk

         Market risk is defined as the possibility of negative impacts resulting from fluctuation in the market values of positions in financial instruments held by the Group. At BB Seguridade and its subsidiaries, the exposure to this risk arises from the investment portfolio in financial assets. According to the latest Relevant Risks Inventory and considering the Financial Investment Policy and current portfolio, the risk is not considered relevant.

         The market risk is managed based in the Financial Investment Policy, that defines which assets may comprise the portfolio and the VaR (Value at Risk) limit, calculated for 21 business days, with the portfolio volatility estimated using the exponentially weighted moving average (EWMA) and 95% confidence level. The indicator is monitored by the Finance and Investment Committee and by the Board of Directors.

         Sensitivity analysis on market risk factors

         On March 31, 2026, there were no derivative instruments in the Group's portfolio, which was entirely composed of post-fixed financial instruments linked to Selic rate. Based on the studies carried out, there is no relevant exposure to market risk factors.

      3. Credit Risk

         The credit risk is defined by the Group as the possibility of negative impacts associated to the non-fulfillment, by a borrower or a counterparty, of its corresponding financial obligations according to negotiated terms, and/or to the devaluation of receivables due to a drop in the borrower's or counterparty's risk rating. At BB Seguridade and its subsidiaries BB Seguros and BB Corretora, the exposure to this risk arises from the investment portfolio in financial assets, which is composed of Bonds issued by private counterparties. However, currently, the portfolio does not include securities issued by private counterparties. Therefore, exposure to this risk is not relevant.

         The credit risk arising from the payment of brokerage for products sold by BB Corretora is considered duly mitigated due to the nature of the Group's operation, since most of the business takes place through the Banco do Brasil channel, whose brokerage is transferred automatically.

      4. Liquidity Risk and capital management

         Liquidity risk is defined by the Group as the possibility of negative impacts due to the lack of resources to honor its obligations due to the mismatch between assets and liabilities.

         BB Seguridade and its subsidiaries maintain assets with a high degree of conversion in cash to cover liabilities and other expected allocations to short term. The parameters used are defined by the Financial Investment Policy and the Capital Plan.

         The Capital Plan, prepared for a minimum three-year horizon, presents the projected financial flows from the operational activity, such as compensation from commissions, equity interests, expenses inherent to the Group's activities and those resulting from strategic movements, such as allocation of funds to equity interests, strategic investments, divestitures and disposals and considers the maintenance of a liquidity margin in order to keep the financial balance in case of unpredictable events.

         The BB Seguridade and its subsidiaries main liabilities refer to administrative costs, payment of taxes and dividends, as presented below.

         (1) Unearned commissions refer to brokerage revenues to be recognized over the course of the insurance contracts, and such revenues will be realized over the term of these operations, and whose corresponding amounts are received, in large part, before that date. Therefore, in general, commissions to be appropriated do not represent amounts to be disbursed and, consequently, do not generate relevant impacts on the company's liquidity.

   2. Risk Governance applied to Affiliated Companies

      BB Seguridade's affiliated companies maintain their own risk management structures compatible with the nature and complexity of their businesses, being regulated by the Superintendence of Private Insurance (Susep), in accordance with the requirements established in CNSP Resolutions 416/2021 and 432/2021 and subsequent amendments and Susep Circular 648/2021 and subsequent amendments. For companies regulated by the National Supplementary Health Agency (ANS), Normative Resolution 518/2022 provides for the adoption of minimum corporate governance practices, with an emphasis on internal controls and risk management, for the purposes of solvency of health care plan operators.

      CNSP Resolution No. 416/2021 and subsequent amendments informs about the integration of the Internal Controls System to the Risk Management Structure of investments, with the obligation to have a statutory Director responsible for internal controls and compliance, in addition to the need for specific policies on managed risks, and a statutory risk committee with the presence of independent members.

      Circular Susep 666/2022 provides for sustainability requirements, to be observed by insurance companies, open private pension entities (EAPCs), capitalization companies and local reinsurers.

      Based on the results of the work carried out by the investees, BB Seguridade continuously monitors and assesses the levels of risk exposure, acting, via governance, to ensure the adoption of the best risk management practices in its investees.

      1. Liquidity, solvency, and capital management

   In the capital management of affiliated companies supervised by Susep, the main indicator used is the Minimum Required Capital (CMR), which represents the total capital that a company must maintain, at any time, to operate, and aims to guarantee the risks inherent to its operations, as regulated by CNSP Resolution 432/2021 and subsequent amendments.

   CMR is composed of portions relating to underwriting, credit, operational and market risks, and the solvency capital requirement adequacy is measured using the Adjusted Net Equity (PLA) of the entity, which must be equal to or above the calculated CMR.

   CNSP Resolution 432/2021 and subsequent amendments establishes technical provisions calculation models and requires additional liquid assets to maintain the company's liquidity. In addition, it contains criteria for the preparation of solvency and liquidity regularization plans in cases of regulatory non-compliance. It is important to highlight that the investees, according to guidelines defined by the Group, do not have an appetite for the risk of non-compliance with regulatory solvency.

   For companies regulated by the National Agency of Supplementary Health (ANS), there are rules for recognition of technical reserves, PLA criteria and Solvency Margin criteria according to Regulatory Resolution 569/2022.

   For investments, where minimum capital is required, there is a search for maintaining additional capital to the regulatory one, to minimize the chances of non-compliance with the required amounts and in line with the risk appetite defined by their Board of Directors.

   On March 31, 2026, considering the data provided by each investee, all companies in which BB Seguridade holds interests and that are subject to regulatory capital requirements, had sufficient capital, solvency, and coverage of technical provisions, in accordance with current legislation applicable.
