Notes To Condensed Consolidated Financial Statements

(Dollar amounts in millions, except for per share data, unless otherwise stated)

(Unaudited)

1. Basis of Presentation and Significant Accounting Policies

Basis of Presentation

The Hartford Insurance Group, Inc. is a holding company for insurance and financial services subsidiaries that provide property and casualty insurance, employee group benefits insurance and services, and mutual funds and exchange-traded funds ("ETF") to individual and business customers in the United States as well as in the United Kingdom and other international locations (collectively, “The Hartford”, the “Company”, “we” or “our”).

The Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information, which differ materially from the accounting practices prescribed by various insurance regulatory authorities. These Condensed Consolidated Financial Statements and Notes should be read in conjunction with the Consolidated Financial Statements and Notes thereto included in the Company's 2024 Form 10-K Annual Report. The results of operations for interim periods are not necessarily indicative of the results that may be expected for the full year.

The accompanying Condensed Consolidated Financial Statements and Notes are unaudited. These financial statements reflect all adjustments (generally consisting only of normal accruals) which are, in the opinion of management, necessary for the fair statement of the financial position, results of operations and cash flows for the interim periods.

Consolidation

The Condensed Consolidated Financial Statements include the accounts of The Hartford Insurance Group, Inc., and entities in which the Company directly or indirectly has a controlling financial interest. Entities in which the Company has significant influence over the operating and financing decisions but does not control are reported using the equity method. Intercompany transactions and balances between The Hartford and its subsidiaries and affiliates have been eliminated.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

The most significant estimates include those used in determining property and casualty and group long-term disability ("LTD") insurance product reserves, net of reinsurance; evaluation of goodwill for impairment; valuation of investments and derivative instruments; and contingencies relating to corporate litigation and regulatory matters.

Reclassifications

Certain reclassifications have been made to prior year financial information to conform to the current year presentation.

Future Adoption of New Accounting Standards

Internally Developed Software Costs

The Financial Accounting Standards Board (“FASB”) issued new guidance on theaccounting for internally developed software costs. Under the new guidance, costs associated with software developed for internal use will now be capitalized when management authorizes a project and when it is probable the project will be completed and used to perform the function intended, rather than when a project reaches the application development stage under existing guidance. The guidance is effective beginning January 1, 2028, with early adoption permitted, and can beapplied prospectively, retrospectively, or on a modified retrospective basis. The Company has not yet determined the transition method, timing for adoption, or estimated the effect on the Company’s financial statements.

4. Fair Value Measurements

The Company carries certain financial assets and liabilities at estimated fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants. Our fair value framework includes a hierarchy that gives the highest priority to the use of quoted prices in active markets, followed by the use of market observable inputs, followed by the use of unobservable inputs.

The fair value hierarchy levels are as follows:

Level 1 Fair values based on unadjusted quoted prices for identical assets or liabilities, in active markets that the Company has the ability to access at the measurement date.

Level 2 Fair values primarily based on observable inputs, other than quoted prices included in Level 1, or based on prices for similar assets and liabilities.

Level 3 Fair values derived when one or more of the significant inputs are unobservable (including assumptions about risk). With little or no observable market, the determination of fair values uses considerable judgment and represents the Company’s best estimate of an amount that could be realized in a market exchange for the asset or liability. Also included are securities that are traded within illiquid markets and/or priced by independent brokers.

The Company will classify the financial asset or liability by level based upon the lowest level input that is significant to the determination of the fair value. In most cases, both observable inputs (e.g., changes in interest rates) and unobservable inputs (e.g., changes in risk assumptions) are used to determine fair values that the Company has classified within Level 3.

[1]Level 3 includes investments that have contractual sales restrictions that require consent to sell and are in place for the duration that the securities are held by the Company.

[2]Includes derivative instruments in a net positive fair value position after consideration of the accrued interest and impact of collateral posting requirements which may be imposed by agreements and applicable law. See footnote 3 to this table for derivative liabilities.

[3]Includes derivative instruments in a net negative fair value position (derivative liability) after consideration of the accrued interest and impact of collateral posting requirements which may be imposed by agreements and applicable law.

The Company has overseas deposits included in other investments of $80 and $61 as of September 30, 2025 and December 31, 2024, respectively, which are measured at fair value using the net asset value as a practical expedient.

Fixed Maturities, Equity Securities, Short-term Investments, and Derivatives

Valuation Techniques

The Company generally determines fair values using valuation techniques that use prices, rates, and other relevant information evident from market transactions involving identical or similar

instruments. Valuation techniques also include, where appropriate, estimates of future cash flows that are converted into a single discounted amount using current market expectations. The Company uses a "waterfall" approach comprised of the following pricing sources and techniques, which are listed in priority order:

•Quoted prices, unadjusted, for identical assets or liabilities in active markets, which are classified as Level 1.

•Prices from third-party pricing services, which primarily utilize a combination of techniques. These services utilize recently reported trades of identical, similar, or benchmark securities making adjustments for market observable inputs available through the reporting date. If there are no recently reported trades, they may use a discounted cash flow

technique to develop a price using expected cash flows based upon the anticipated future performance of the underlying collateral discounted at an estimated market rate. Both techniques develop prices that consider the time value of future cash flows and provide a margin for risk, including liquidity and credit risk. Most prices provided by third-party pricing services are classified as Level 2 because the inputs used in pricing the securities are observable. However, some securities that are less liquid or trade less actively are classified as Level 3. Additionally, certain long-dated securities include benchmark interest rate or credit spread assumptions that are not observable in the marketplace and are thus classified as Level 3.

•Internal matrix pricing is a valuation process internally developed for private placement securities for which the Company is unable to obtain a price from a third-party pricing service. Internal pricing matrices determine credit spreads that, when combined with risk-free rates, are applied to contractual cash flows to develop a price. The Company develops credit spreads using market based data for public securities adjusted for credit spread differentials between public and private securities, which are obtained from a survey of multiple private placement brokers. The market-based reference credit spread considers the issuer’s sector, financial strength, and term to maturity, using an independent public security index, while the credit spread differential considers the non-public nature of the security. Securities priced using internal matrix pricing are classified as Level 2 because the significant inputs are observable or can be corroborated with observable data.

•Independent broker quotes, which are typically non-binding, use inputs that can be difficult to corroborate with observable market-based data. Brokers may use present value techniques using assumptions specific to the security types, or they may use recent transactions of similar securities. Due to the lack of transparency in the process that brokers use to develop prices, valuations that are based on independent broker quotes are classified as Level 3.

The fair value of derivative instruments is determined primarily using a discounted cash flow model or option model technique and incorporates counterparty credit risk. In some cases, quoted market prices for exchange-traded and over-the-counter ("OTC") cleared derivatives may be used and in other cases

independent broker quotes may be used. The pricing valuation models primarily use inputs that are observable in the market or can be corroborated by observable market data. The valuation of certain derivatives may include significant inputs that are unobservable, such as volatility levels, and reflect the Company’s view of what other market participants would use when pricing such instruments.

Valuation Controls

The process for determining the fair value of investments is monitored by the Valuation Committee, which is a cross-functional group of senior management within the Company. The purpose of the Valuation Committee is to provide oversight of the pricing policy, procedures, and controls, including approval of valuation methodologies and pricing sources. The Valuation Committee reviews market data trends, pricing statistics and trading statistics to ensure that prices are reasonable and consistent with our fair value framework. Controls and procedures used to assess third-party pricing services are reviewed by the Valuation Committee, including the results of annual due-diligence reviews. Controls include, but are not limited to, reviewing daily and monthly price changes, stale prices, and missing prices and comparing new trade prices to third-party pricing services, weekly price changes to published bond index prices, and daily OTC derivative market valuations to counterparty valuations. The Company has a dedicated pricing group that works with trading and investment professionals to challenge prices received by a third-party pricing source if the Company believes that the valuation received does not accurately reflect the fair value. New valuation models and changes to current models require approval by the Valuation Committee. In addition, the Company’s enterprise-wide Operational Risk Management function provides an independent review of the suitability and reliability of model inputs, as well as an analysis of significant changes to current models.

Valuation Inputs

Quoted prices for identical assets in active markets are considered Level 1 and consist of on-the-run U.S. Treasuries, money market funds, exchange-traded equity securities, open-ended mutual funds, certain short-term investments, and exchange traded derivative instruments.

[1]The weighted average is determined based on the fair value of the securities.

[2]Conversely, the impact of a decrease in input would have the opposite impact to the fair value as that presented in the table.

[3]Excludes securities for which the Company bases fair value on broker quotations.

[4]Excludes securities for which the Company bases fair value on broker quotations; however, included are broker priced lower-rated private placement securities for which the Company receives spread and yield information to corroborate the fair value.

[5]Decrease for above market rate coupons and increase for below market rate coupons.

[6]Generally, a change in the assumption used for the constant default rate would have been accompanied by a directionally similar change in the assumption used for the loss severity and a directionally opposite change in the assumption used for constant prepayment rate and would have resulted in wider spreads.

As of September 30, 2025 and December 31, 2024, the fair values of the Company's level 3 derivatives were less than $1 for both periods.

The table above excludes certain securities for which fair values are predominately based on independent broker quotes. While the Company does not have access to the significant unobservable inputs that independent brokers may use in their pricing process, the Company believes brokers likely use inputs similar to those used by the Company and third-party pricing services to price similar instruments. As such, in their pricing models, brokers likely use estimated loss severity rates, prepayment rates, constant default rates and credit spreads. Therefore, similar to non-broker priced securities, increases in these inputs would generally cause fair values to decrease. As of September 30, 2025, no significant adjustments were made by the Company to broker prices received.

Level 3 Assets and Liabilities Measured at Fair Value on a Recurring Basis Using Significant Unobservable Inputs

The Company uses derivative instruments to manage the risk associated with certain assets and liabilities. However, the derivative instrument may not be classified within the same fair value hierarchy level as the associated asset or liability.

[1]Amounts in these columns are generally reported innet realized gains (losses). All amounts are before income taxes.

[2]All amounts are before income taxes.

[3]Transfers into and/or (out of) Level 3 are primarily attributable to the availability of market observable information and the re-evaluation of the observability of pricing inputs.

[4]Derivative instruments are reported in this table on a net basis for asset (liability) positions and reported in the Condensed Consolidated Balance Sheets in other investments and other liabilities.

[1]All amounts in these rows are reported innet realized gains (losses). All amounts are before income taxes.

[2]Amounts presented are for Level 3 only and therefore may not agree to other disclosures included herein.

[3]Changes in unrealized gains (losses) on fixed maturities, AFS are reported in changes in net unrealized gain (loss) on fixed maturities in the Condensed Consolidated Statements of Comprehensive Income (Loss).

Fair Value Option

The Company has elected the fair value option for certain investments in residual interests of securitizations and other securities that contain embedded credit derivatives with underlying credit risk related to residential real estate in order to reflect changes in fair value in earnings. These instruments are included within FVO securities on the Condensed Consolidated Balance Sheets and changes in the fair value of these investments are reported in net realized gains and losses.

As of September 30, 2025 and December 31, 2024, the fair value of assets using the fair value option was $191 and $308, respectively, of which $191 and $197, respectively, were residual interests of securitizations.

For the three and nine months ended September 30, 2025, net realized gains (losses) related to the change in fair value of assets using the fair value option were $7 and $(10), respectively. For the three and nine months ended September 30, 2024, net realized losses related to the change in fair value of assets using the fair value option were $5 and $2, respectively.

Financial Instruments Not Carried at Fair Value

[1]As of September 30, 2025 and December 31, 2024, the carrying amount of mortgage loans is net of ACL of $49 and $44, respectively.

[2]Included in long-term debt in the Condensed Consolidated Balance Sheets, except for any current maturities, which are included in short-term debt when applicable.

5. Investments

[1]The change in net unrealized gains on equity securities still held as of September 30, 2025, and included in net realized gains were $28 and $45 for the three and nine months ended September 30, 2025, respectively. The change in net unrealized gains (losses) on equity securities still held as of September 30, 2024, and included in net realized gains (losses) were $27 and $71 for the three and nine months ended September 30, 2024, respectively.

[2]For the three and nine months ended September 30, 2025, includes gains (losses) from transactional foreign currency revaluation of $7 and $(11), respectively, and losses on non-qualifying derivatives of $(5) and $(16), respectively. For the three and nine months ended September 30, 2024, includes losses from transactional foreign currency revaluation of $(11) and $(5), respectively, and gains on non-qualifying derivatives of $23 and $15, respectively.

Proceeds from the sales of fixed maturities, AFS totaled $1.6 billion and $4.3 billion for the three and nine months ended September 30, 2025, respectively, and $1.5 billion and $4.2 billion for the three and nine months ended September 30, 2024. Non-cash investing activities for both the three and nine months ended September 30, 2025, included $17 related to the exchange of equity securities for limited partnerships and other alternative investments. Non-cash investing activities for both the three and nine months ended September 30, 2024, included $18 related to the exchange of short-term investments for equity securities.

Accrued Investment Income on Fixed Maturities, AFS and Mortgage Loans

As of September 30, 2025 and December 31, 2024, the Company reported accrued investment income related to fixed maturities, AFS of $438 and $412, respectively, and accrued investment income related to mortgage loans of $24 and $22, respectively. These amounts are not included in the carrying value of the fixed maturities or mortgage loans. Investment income on fixed maturities and mortgage loans is accrued unless it is past due over 90 days or management deems the interest uncollectible. The Company does not include the current accrued investment income balance when estimating the ACL. The Company has a policy to write-off accrued investment income balances that are more than 90 days past due. Write-offs of accrued investment income are recorded as a credit loss component of net realized gains and losses.

Recognition and Presentation of Intent-to-Sell Impairments and ACL on Fixed Maturities, AFS

The Company will record an "intent-to-sell impairment" as a reduction to the amortized cost of fixed maturities, AFS in an unrealized loss position if the Company intends to sell or it is more likely than not that the Company will be required to sell the fixed maturity before a recovery in value. A corresponding charge is recorded in net realized losses equal to the difference between the fair value on the impairment date and the amortized cost basis of the fixed maturity before recognizing the impairment.

For fixed maturities where a credit loss has been identified and no intent-to-sell impairment has been recorded, the Company will record an ACL for the portion of the unrealized loss related to the credit loss. Any remaining unrealized loss on a fixed maturity after recording an ACL is the non-credit amount and is recorded in OCI. The ACL is the excess of the amortized cost over the greater of the Company's best estimate of the present value of expected future cash flows or the security's fair value. Cash flows are discounted at the effective yield that is used to record interest income. The ACL cannot exceed the unrealized loss and, therefore, it may fluctuate with changes in the fair value of the fixed maturity if the fair value is greater than the Company's best estimate of the present value of expected future cash flows. The initial ACL and any subsequent changes are recorded in net realized gains and losses. The ACL is written off against the amortized cost in the period in which all or a portion of the related fixed maturity is determined to be uncollectible.

Developing the Company’s best estimate of expected future cash flows is a quantitative and qualitative process that incorporates information received from third-party sources along with certain internal assumptions regarding the future performance. The Company's considerations include, but are not limited to, (a) changes in the financial condition of the issuer and/or the underlying collateral, (b) whether the issuer is current on contractually obligated interest and principal payments, (c) credit ratings, (d) payment structure of the security and (e) the extent to which the fair value has been less than the amortized cost of the security.

For non-structured securities, assumptions include, but are not limited to, economic and industry-specific trends and fundamentals, instrument-specific developments including changes in credit ratings, industry earnings multiples and the issuer’s ability to restructure, access capital markets, and execute asset sales.

For structured securities, assumptions include, but are not limited to, various performance indicators such as historical and projected default and recovery rates, credit ratings, current and projected delinquency rates, loan-to-value ("LTV") ratios, average cumulative collateral loss rates that vary by vintage year, prepayment speeds, and property value declines. These assumptions require the use of significant management judgment and include the probability of issuer default and estimates regarding timing and amount of expected recoveries, which may include estimating the underlying collateral value.

Fixed Maturities, AFS

Estimated maturities may differ from contractual maturities due to call or prepayment provisions. Due to the potential for variability in payment speeds (i.e., prepayments or extensions), mortgage-backed and asset-backed securities are not categorized by contractual maturity.

Concentration of Credit Risk

The Company aims to maintain a diversified investment portfolio including issuer, sector and geographic stratification, where applicable, and has established certain exposure limits, diversification standards and review procedures to mitigate credit risk. The Company hadno investment exposure to any credit concentration risk of a single issuer greater than 10% of the Company's stockholders' equity as of September 30, 2025 or December 31, 2024 other than U.S. government securities and certain U.S. government agencies.

Unrealized Losses on Fixed Maturities, AFS

As of September 30, 2025, fixed maturities, AFS in an unrealized loss position consisted of 2,780 instruments and were primarily depressed due to higher interest rates and/or wider credit spreads since the purchase date. As of September 30, 2025,95% of these fixed maturities were depressed less than 20% of cost or amortized cost. The decrease in unrealized losses during the nine months ended September 30, 2025, was primarily attributable to lower interest rates and tighter credit spreads.

Most of the fixed maturities depressed for twelve months or more relate to the corporate sector, municipal bonds, and RMBS, which were primarily depressed because current rates are higher and/or market spreads are wider than at the respective purchase dates. The Company neither has an intention to sell nor does it expect to be required to sell the fixed maturities outlined in the preceding discussion. The decision to record credit losses on fixed maturities, AFS in the form of an ACL requires us to make qualitative and quantitative estimates of expected future cash flows.

Mortgage Loans

ACL on Mortgage Loans

The Company reviews mortgage loans on a quarterly basis to estimate the ACL with changes in the ACL recorded in net realized gains and losses. Apart from an ACL recorded on individual mortgage loans where the borrower is experiencing financial difficulties, the Company records an ACL on the pool of mortgage loans based on lifetime expected credit losses. The Company utilizes a third-party forecasting model to estimate lifetime expected credit losses at a loan level under multiple economic scenarios. The scenarios use macroeconomic data provided by an internationally recognized economics firm that generates forecasts of varying economic factors such as GDP growth, unemployment and interest rates. The economic scenarios are projected over 10 years. The first two to four years of the 10-year period assume a specific modeled economic scenario (including moderate upside, moderate recession and severe recession scenarios) and then revert to historical long-term assumptions over the remaining period. Using these economic scenarios, the forecasting model projects

property-specific operating income and capitalization rates used to estimate the value of a future operating income stream. The operating income and the property valuations derived from capitalization rates are compared to loan payment and principal amounts to create debt service coverage ratios ("DSCRs") and LTVs over the forecast period. The Company's process also considers qualitative factors. The model overlays historical data about mortgage loan performance based on DSCRs and LTVs and projects the probability of default, amount of loss given a default and resulting expected loss through maturity for each loan under each economic scenario. Economic scenarios are probability-weighted based on a statistical analysis of the forecasted economic factors and qualitative analysis. The Company records the change in the ACL on mortgage loans based on the weighted-average expected credit losses across the selected economic scenarios.

When a borrower is experiencing financial difficulty, including when foreclosure is probable, the Company measures an ACL on individual mortgage loans. The ACL is established for any shortfall between the amortized cost of the loan and the fair value of the collateral less costs to sell. Estimates of collectibility from an individual borrower require the use of significant management judgment and include the probability and timing of borrower default and loss severity estimates. In addition, cash flow projections may change based upon new information about the borrower's ability to pay and/or the value of underlying collateral such as changes in projected property value estimates. During the period in which all or a portion of the mortgage loan is determined to be uncollectible, the ACL is written off against the amortized cost.

There wereno mortgage loans held-for-sale as of September 30, 2025 or December 31, 2024. For the three and nine months ended September 30, 2025, the Company hadno mortgage loans that have had extensions or restructurings other than what is allowable under the original terms of the contract or with borrowers experiencing financial difficulties. For the three

and nine months ended September 30, 2024, one office property mortgage loan with an amortized cost of $9 was granted a term extension of three years at the original rate which is a below-market rate with a borrower experiencing financial difficulties. The modified loan represented less than 1% of the portfolio and is current and performing in conjunction with the modified terms.

The weighted-average LTV ratio of the Company’s mortgage loan portfolio was 56% as of September 30, 2025, while the weighted-average LTV ratio at origination of these loans was 58%. LTV ratios compare the loan amount to the value of the underlying property collateralizing the loan with property values based on appraisals updated no less than annually. Factors considered in estimating property values include, among other things, actual and expected property cash flows, geographic market data and the ratio of the property's net operating income to its value. DSCR compares a property’s net operating income to the borrower’s principal and interest payments and are updated no less than annually through reviews of underlying properties.

[1]Primarily comprised of grocery-anchored retail centers, withno exposure to regional shopping malls.

Past-Due Mortgage Loans

Mortgage loans are considered past due if a payment of principal or interest is not received according to the contractual terms of the loan agreement, which typically includes a grace period. As of September 30, 2025 and December 31, 2024, the Company heldno mortgage loans considered past due.

Mortgage Servicing

The Company originates, sells and services commercial mortgage loans on behalf of third parties and recognizes servicing fee income over the period that services are performed. As of September 30, 2025, under this program, the Company serviced mortgage loans with a total outstanding principal of $10.3 billion, of which $4.8 billion was serviced on behalf of third parties and $5.5 billion was retained and reported in total investments on the Company's Condensed Consolidated Balance Sheets. As of December 31, 2024, the Company serviced mortgage loans with a total outstanding principal balance of $10.0 billion, of which $4.8 billion was serviced on behalf of third parties and $5.2 billion was retained and reported in total investments on the Company's Condensed Consolidated Balance Sheets. Servicing rights are carried at the lower of cost or fair value and were $0 as of September 30, 2025 and December 31, 2024, because servicing fees were market-level fees at origination and remain adequate to compensate the Company for servicing the loans.

Variable Interest Entities

The Company is engaged with various special purpose entities and other entities that are deemed to be variable interest entities ("VIEs") primarily as an investor through normal investment activities or, at times, as an investment manager.

A VIE is an entity that either has investors that lack certain essential characteristics of a controlling financial interest, such as simple majority kick-out rights, or lacks sufficient funds to finance its own activities without financial support provided by other entities. The Company performs ongoing qualitative assessments of its VIEs to determine whether the Company has a controlling financial interest in the VIE and therefore is the primary beneficiary. The Company is deemed to have a controlling financial interest when it has both the ability to direct the activities that most significantly impact the economic performance of the VIE and the obligation to absorb losses or right to receive benefits from the VIE that could potentially be significant to the VIE. Based on the Company’s assessment, if it determines it is the primary beneficiary, the Company

consolidates the VIE in the Company’s Condensed Consolidated Financial Statements.

Consolidated VIEs

As of September 30, 2025 and December 31, 2024, the Company didnot hold any securities for which it is the primary beneficiary.

Non-Consolidated VIEs

The Company, through normal investment activities, makes passive investments in limited partnerships and other alternative investments. For these non-consolidated VIEs, the Company has determined it is not the primary beneficiary as it has no ability to direct activities that could significantly affect the economic performance of the investments. The Company’s maximum exposure to loss as of September 30, 2025 and December 31, 2024 was limited to the total carrying value of $3.8 billion and $3.2 billion, respectively, which are a portion of the investments in limited partnerships and other alternative investments in the Company's Condensed Consolidated Balance Sheets that are primarily recorded using the equity method of accounting. As of September 30, 2025 and December 31, 2024, the Company has outstanding commitments totaling $2.0 billion for both periods, whereby the Company is committed to fund these investments and may be called by the partnership during the commitment period to fund the purchase of new investments and partnership expenses. These investments are generally of a passive nature in that the Company does not take an active role in management. For further discussion of these investments, see Equity Method Investments within Note 5 - Investments of Notes to Consolidated Financial Statements included in the Company’s 2024 Form 10-K Annual Report.

Furthermore, the Company makes investments in entities that sponsor affordable housing projects. Similarly, for these non-consolidated VIEs, the Company has determined it is not the primary beneficiary as it has no ability to direct activities that could significantly affect the economic performance of the investments. The Company applies the proportional amortization method to subsequently measure its investments in such qualified affordable housing projects, where costs are amortized over the period in which the investor expects to receive tax credits and the resulting amortization is recognized as a component of income tax expense on the Company's Condensed Consolidated Statements of Operations. For the three and nine months ended September 30, 2025, the Company recognized amortization of $4 and $12, respectively, and related tax benefits of $6 and $19, respectively. For the three and nine months ended September 30, 2024, the Company recognized amortization of $1 and $3, respectively, and related tax benefits of $3 and $8, respectively. The income tax credits and other income tax benefits are recognized in operating activities in the Condensed Consolidated Statement of Cash Flows. The carrying value of these investments, which are reported in other assets on the Company’s Condensed Consolidated Balance Sheets was $97 and $51 as of September 30, 2025, and December 31, 2024, respectively. As of September 30, 2025 and December 31, 2024, the Company has outstanding commitments related to affordable housing projects of $209 and $267, respectively, that are contingent on various conditions precedent to funding.

In addition, the Company makes passive investments in structured securities issued by VIEs for which the Company is not the manager. These investments are included in ABS, CLOs, CMBS, and RMBS and are reported in fixed maturities, AFS, and FVO securities on the Company's Condensed Consolidated Balance Sheets. The Company has not provided financial or other support with respect to these investments other than its original investment. For these investments, the Company determined it is not the primary beneficiary due to the relative size of the Company’s investment in comparison to the principal amount of the structured securities issued by the VIEs, the Company’s inability to direct the activities that most significantly impact the economic performance of the VIEs, and, where applicable, the level of credit subordination which reduces the Company’s obligation to absorb losses or right to receive benefits. The Company’s maximum exposure to loss on these investments is limited to the amount of the Company’s investment.

Reverse Repurchase Agreements, Collateral Transactions and Restricted Investments

Reverse Repurchase Agreements

From time to time, the Company enters into reverse repurchase agreements where the Company purchases securities and simultaneously agrees to resell the same or substantially the same securities. The maturity of these transactions is generally within one year. The agreements require additional collateral to be transferred to the Company under specified conditions and the Company has the right to sell or re-pledge the securities received. The Company accounts for reverse repurchase agreements as collateralized financing. As of September 30, 2025 and December 31, 2024, the Company reported $51 and $0, respectively, within short-term investments on the Condensed Consolidated Balance Sheets representing a receivable for the amount of cash transferred to purchase securities.

Collateral Transactions

As of both September 30, 2025 and December 31, 2024, the Company pledged collateral of $1, of U.S. government securities or cash primarily related to certain bank loan participations committed through a limited partnership agreement.

For disclosure of collateral in support of derivative transactions, refer to the Derivative Collateral Arrangements section in Note 6 - Derivatives of Notes to Condensed Consolidated Financial Statements.

Other Restricted Investments

The Company is required by law to deposit securities with government agencies in certain states in which it conducts business. In addition, the Company is required to hold fixed maturities and short-term investments in trust for the benefit of syndicate policyholders, hold fixed maturities in a Lloyd's of London ("Lloyd's") trust account to provide a portion of the required capital, and maintain other investments primarily consisting of overseas deposits in various countries with Lloyd's to support underwriting activities in those countries. Lloyd's is an insurance market-place operating worldwide. Lloyd's does not underwrite risks. The Company accepts risks as the sole member of Lloyd's Syndicate 1221 ("Lloyd's Syndicate").

The following table presents the components of the Company’s exposure to other restricted investments.

6. Derivatives

The Company utilizes a variety of OTC, OTC-cleared and exchange traded derivative instruments as a part of its overall risk management strategy as well as to enter into replication transactions or income generation covered call transactions. Derivative instruments are used to manage risk associated with interest rate, equity market, credit spread, issuer default, price, and currency exchange rate or volatility. Replication transactions may be used as an economical means to synthetically replicate the characteristics and performance of assets that are permissible investments under the Company’s investment policies.

Strategies that Qualify for Hedge Accounting

Some of the Company's derivatives satisfy hedge accounting requirements as outlined in Note 1 - Basis of Presentation and Significant Accounting Policies of Notes to Consolidated Financial Statements, included in The Hartford’s 2024 Form 10-K Annual Report. Typically, these hedging instruments include interest rate swaps and, to a lesser extent, foreign currency swaps where the terms or expected cash flows of the hedged item closely match the terms of the swap.

Cash Flow Hedges

Interest rate swaps are predominantly used to manage portfolio duration and better match cash receipts from assets with cash disbursements required to fund liabilities. These derivatives primarily convert interest receipts on variable-rate fixed maturity securities to fixed rates. The Company has also entered into interest rate swaps to convert the variable interest payments on the $500 junior subordinated debentures due 2067 to fixed interest payments. For further information, see the Junior Subordinated Debentures section within Note 13 - Debt of Notes to Consolidated Financial Statements, included in The Hartford's 2024 Form 10-K Annual Report.

Foreign currency swaps are used to convert foreign currency denominated cash flows related to certain investment receipts to U.S. dollars in order to reduce cash flow fluctuations due to changes in currency rates.

Non-qualifying Strategies

Derivative relationships that do not qualify for hedge accounting (“non-qualifying strategies”) primarily include hedges of interest rate, foreign currency, and equity risk of certain fixed maturities and equities. In addition, hedging and replication strategies that utilize credit default swaps do not qualify for hedge accounting. The non-qualifying strategies include:

Credit Contracts

Credit default swaps are used to purchase credit protection on an individual entity or referenced index to economically hedge against default risk and credit-related changes in the value of fixed maturity securities. Credit default swaps are also used to assume credit risk related to an individual entity or referenced index as a part of replication transactions. These contracts require the Company to pay or receive a periodic fee in exchange for compensation from the counterparty or the Company should the referenced security issuers experience a credit event, as defined in the contract. The Company also enters into credit default swaps to terminate existing credit default swaps, thereby offsetting the changes in value of the original swap going forward.

Interest Rate Swaps and Futures

The Company uses interest rate swaps and, to a lesser extent, futures to manage interest rate duration between assets and liabilities. In addition, the Company enters into interest rate swaps to terminate existing swaps, thereby offsetting the changes in value of the original swap going forward. As of September 30, 2025 and December 31, 2024, the notional amount of interest rate swaps in offsetting relationships was $333 and $344, respectively.

Foreign Currency Swaps

The Company enters into foreign currency swaps to convert the foreign currency exposures of certain foreign currency-denominated fixed maturity investments to U.S. dollars.

Equity Index Options

The Company enters into equity index options to hedge the impact of a decline in the equity markets on the investment portfolio.

Derivative Balance Sheet Classification

For reporting purposes, the Company has elected to offset within assets or liabilities based upon the net of the fair value amounts, income accruals, and related cash collateral receivables and payables of OTC derivative instruments executed in a legal entity and with the same counterparty under a master netting agreement, which provides the Company with the legal right of offset. The following fair value amounts do not include income accruals or related cash collateral receivables and payables, which are netted with derivative fair value amounts to determine balance sheet presentation. The Company’s derivative instruments are held for risk management purposes, unless otherwise noted in the following table. The notional amount of derivative contracts represents the basis upon which payments or receipts are calculated and is presented in the table to quantify the volume of the Company’s derivative activity. Notional amounts are not necessarily reflective of credit risk.

Offsetting of Derivative Assets/Liabilities

The following tables present the gross fair value amounts, the offsetting amounts, and net position of derivative instruments eligible for offset in the Company's Condensed Consolidated Balance Sheets. Offsetting amounts include fair value amounts, income accruals and related cash collateral receivables and payables associated with derivative instruments that are traded under a common master netting agreement, as described in the preceding discussion. Also included in the tables are financial collateral receivables and payables, which are contractually permitted to be offset upon an event of default, although are disallowed for offsetting under U.S. GAAP.

[1]Included in other investments in the Company's Condensed Consolidated Balance Sheets.

[2]Included in other liabilities in the Company's Condensed Consolidated Balance Sheets and is limited to the net derivative payable associated with each counterparty.

[3]Included in other investments in the Company's Condensed Consolidated Balance Sheets and is limited to the net derivative receivable associated with each counterparty.

[4] Excludes collateral associated with exchange-traded derivative instruments.

Cash Flow Hedges

For derivative instruments that are designated and qualify as cash flow hedges, the gain or loss on the derivative is reported as a component of OCI and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. All components of each derivative’s gain or loss were included in the assessment of hedge effectiveness.

As of September 30, 2025, the before tax deferred net losses on derivative instruments recorded in AOCI that are expected to be reclassified to earnings during the next twelve months are $26. This expectation is based on the anticipated interest payments on hedged investments in fixed maturity securities and long-term debt that will occur over the next twelve months. At that time, the Company will recognize the deferred net gains (losses) as an adjustment to net investment income or interest expense, as applicable, over the term of the hedged instrument cash flows.

During the three and nine months ended September 30, 2025 and 2024, the Company hadno net reclassifications from AOCI to earnings resulting from the discontinuance of cash-flow hedges due to forecasted transactions that were no longer probable of occurring.

Non-qualifying Strategies

For non-qualifying strategies, including embedded derivatives that are required to be bifurcated from their host contracts and accounted for as derivatives, the gain or loss on the derivative is recognized currently in earnings within net realized gains (losses).

[1]Excludes investments that contain an embedded credit derivative for which the Company has elected the fair value option. For further discussion, see the Fair Value Option section in Note 4 - Fair Value Measurements of Notes to Condensed Consolidated Financial Statements.

Credit Risk Assumed through Credit Derivatives

The Company enters into credit default swaps that assume credit risk of a single entity or referenced index in order to synthetically replicate investment transactions that are permissible under the Company's investment policies. The Company will receive periodic payments based on an agreed upon rate and notional amount and will only make a payment if there is a credit event. A credit event payment will typically be equal to the notional value of the swap contract less the value of the referenced security issuer’s debt obligation after the occurrence of the credit event. A credit event is generally defined as a default on contractually obligated interest or principal payments or bankruptcy of the referenced entity. The credit default swaps in which the Company assumes credit risk may primarily reference investment grade single corporate issuers and baskets, which include standard diversified portfolios of corporate and CMBS issuers.

[1]The average credit ratings are based on availability and are generally the midpoint of the available ratings among Moody’s, S&P and Fitch. If no rating is available from a rating agency, then an internally developed rating is used.

[2]Notional amount is equal to the maximum potential future loss amount. These derivatives are governed by agreements and applicable law, which include collateral posting requirements. There is no additional specific collateral related to these contracts or recourse provisions included in the contracts to offset losses.

[3]The Company has entered into offsetting credit default swaps to terminate certain existing credit default swaps, thereby offsetting the future changes in value of, or losses paid related to, the original swap.

[4] Comprised of swaps of standard market indices of diversified portfolios of corporate and CMBS issuers referenced through credit default swaps. These swaps are subsequently valued based upon the observable standard market index.

[5] Excludes investments that contain an embedded credit derivative for which the Company has elected the fair value option. For further discussion, see the Fair Value Option section in Note 4 - Fair Value Measurements of Notes to Condensed Consolidated Financial Statements.

Derivative Collateral Arrangements

The Company enters into various collateral arrangements in connection with its derivative instruments, which require both the pledging and accepting of collateral. As of September 30, 2025 and December 31, 2024, the Company has pledged cash collateral associated with derivative instruments of$29 and $31, respectively. In general, collateral receivable is recorded in other assets or other liabilities on the Company's Condensed Consolidated Balance Sheets as determined by the Company's election to offset on the balance sheet. As of September 30, 2025 and December 31, 2024, the Company pledged securities collateral associated with derivative instruments with a fair value of $21 and $1, respectively, which have been included in fixed maturities on the Company's Condensed Consolidated Balance Sheets. The counterparties generally have the right to sell or re-pledge these securities.

In addition, as of September 30, 2025 and December 31, 2024, the Company has pledged initial margin of cash related to OTC-cleared and exchange traded derivatives with a fair value of $7 and $10, respectively, which is recorded in other investments or other assets on the Company's Condensed Consolidated Balance Sheets. As of September 30, 2025 and December 31, 2024, the Company has pledged initial margin of securities related to OTC-cleared and exchange traded derivatives with a fair value of $89 and $103, respectively, which are included within fixed maturities on the Company's Condensed Consolidated Balance Sheets.

As of September 30, 2025 and December 31, 2024, the Company accepted cash collateral associated with derivative instruments of $49 and $78, respectively, which was invested and recorded in the Company's Condensed Consolidated Balance Sheets in fixed maturities and short-term investments with corresponding amounts recorded in other investments or other liabilities as determined by the Company's election to offset on the balance sheet. Also, as of September 30, 2025 and December 31, 2024, the Company didnot hold securities collateral.

7. Premiums Receivable and Agents' Balances

ACL on Premiums Receivable and Agents' Balances

Premiums receivable and agents' balances, excluding receivables for loss sensitive business, are primarily comprised of premiums due from policyholders, which are typically collectible within one year or less. For these balances, the ACL is estimated based on an aging of receivables and recent historical credit loss and collection experience, adjusted for current economic conditions and reasonable and supportable forecasts, when appropriate. Balances are considered past due when amounts that have been billed are not collected within contractually stipulated time periods.

A portion of the Company's Business Insurance business is written with large deductibles or under retrospectively-rated plans (referred to as "loss sensitive business"). Under some commercial insurance contracts with a large deductible, the Company is obligated to pay the claimant the full amount of the claim and the Company is subsequently reimbursed by the policyholder for the deductible amount. As such, the Company is subject to credit risk until reimbursement is made. Retrospectively-rated policies are utilized primarily for workers' compensation coverage, whereby the ultimate premium is adjusted based on actual losses incurred. Although the premium adjustment feature of a retrospectively-rated policy substantially reduces insurance risk for the Company, it presents credit risk to the Company. The Company’s results of operations could be adversely affected if a significant portion of such policyholders failed to reimburse the Company for the deductible amount or the amount of additional premium owed under retrospectively-rated policies. The Company manages these credit risks through credit analysis, collateral requirements, and oversight.

The ACL for receivables for loss sensitive business is estimated as the amount of the receivable exposed to loss multiplied by estimated factors for probability of default and the amount of loss given a default. The probability of default is assigned based on each policyholder's credit rating, or a rating is estimated if no external rating is available. Credit ratings are reviewed and updated at least annually. The exposure amount is estimated net of collateral and other credit enhancement, considering the nature of the collateral, potential future changes in collateral values, and historical loss information for the type of collateral obtained. The probability of default factors are historical corporate defaults for receivables with similar durations estimated through multiple economic cycles. Credit ratings are forward-looking and consider a variety of economic outcomes. The loss given default factors are based on a study of historical recovery rates for general creditors through multiple economic cycles. The Company's evaluation of the required ACL for receivables for loss sensitive business considers the current economic environment as well as the probability-weighted macroeconomic scenarios similar to the approach used for estimating the ACL for mortgage loans. See Note 5 - Investments

8. Reinsurance

The Company cedes insurance risk to reinsurers to enable the Company to manage capital and risk exposure. Such arrangements do not relieve the Company of its primary liability to policyholders. Failure of reinsurers to honor their obligations could result in losses to the Company. The Company's procedures include carefully selecting its reinsurers, structuring agreements to provide collateral funds where necessary, and regularly monitoring the financial condition and ratings of its reinsurers.

Reinsurance Recoverables

Reinsurance recoverables include balances due from reinsurance companies and are presented net of an allowance for uncollectible reinsurance. Reinsurance recoverables include

an estimate of the amount of gross losses and LAE reserves that may be ceded under the terms of the reinsurance agreements, including incurred but not reported ("IBNR") unpaid losses. The Company’s estimate of losses and LAE reserves ceded to reinsurers is based on assumptions that are consistent with those used in establishing the gross reserves for amounts the Company owes to its claimants. The Company estimates its ceded reinsurance recoverables based on the terms of any applicable facultative and treaty reinsurance, including an estimate of how IBNR unpaid losses will ultimately be ceded under reinsurance agreements. Accordingly, the Company’s estimate of reinsurance recoverables is subject to similar risks and uncertainties as the estimate of the gross reserve for unpaid losses and loss adjustment expenses.

Balances are considered past due when amounts that have been billed are not collected within contractually stipulated time periods, generally 30, 60 or 90 days. To manage reinsurer credit risk, a reinsurance security review committee evaluates the credit standing, financial performance, management and operational quality of each potential reinsurer. In placing

reinsurance, the Company considers the nature of the risk reinsured, including the expected liability payout duration, and establishes limits tiered by reinsurer credit rating.

Where its contracts permit, the Company secures future claim obligations with various forms of collateral or other credit enhancement, including irrevocable letters of credit, secured trusts, funds held accounts and group wide offsets. As part of its reinsurance recoverable review, the Company analyzes recent developments in commutation activity between reinsurers and cedants, recent trends in arbitration and litigation outcomes in disputes between cedants and reinsurers and the overall credit quality of the Company’s reinsurers.

Due to the inherent uncertainties as to collection and the length of time before reinsurance recoverables become due, it is possible that future adjustments to the Company’s reinsurance recoverables, net of the allowance, could be required, which could have a material adverse effect on the Company’s consolidated results of operations or cash flows in a particular quarter or annual period.

The allowance for uncollectible reinsurance comprises an ACL and an allowance for disputed balances. The ACL is estimated as the amount of reinsurance recoverables exposed to loss multiplied by estimated factors for the probability of default and the amount of loss given a default. The probability of default is assigned based on each reinsurer's credit rating, or a rating is estimated if no external rating is available. Credit ratings are reviewed on a quarterly basis and any significant changes are reflected in an updated estimate. The probability of default factors are historical insurer and reinsurer defaults for liabilities with similar durations to the reinsured liabilities as estimated through multiple economic cycles. Credit ratings are forward-

looking and consider a variety of economic outcomes. The loss given default factors are based on a study of historical recovery rates for general creditors of corporations through multiple economic cycles or, in the case of purchased annuities funding structured settlements accounted for as reinsurance, historical recovery rates for annuity contract holders.

As shown in the table above, a portion of the total gross reinsurance recoverable balance relates to the Company’s participation in various mandatory (assigned) and voluntary risk pools. Reinsurance recoverables due from pools are backed by the financial position of all insurance companies participating in the pools and the credit backing the reinsurance recoverable is not limited to the financial strength of each pool. The mandatory pools generally are funded through policy assessments or surcharges and if any participant in the pool defaults, remaining liabilities are apportioned among the other members.

The Company's evaluation of the required ACL for reinsurance recoverables considers the current economic environment as well as macroeconomic scenarios similar to the approach used to estimate the ACL for mortgage loans. See Note 5 - Investments. Insurance companies, including reinsurers, are regulated and hold risk-based capital ("RBC") to mitigate the risk of loss due to economic factors and other risks. Non-U.S. reinsurers are either subject to a capital regime substantively equivalent to domestic insurers or we hold collateral to support collection of reinsurance recoverables. As a result, there is limited history of losses from insurer defaults.

9. Reserve for Unpaid Losses and Loss Adjustment Expenses

Property & Casualty Insurance Product Reserves, Net of Reinsurance

Rollforward of Liabilities for Unpaid Losses and Loss Adjustment Expenses

[1] Prior accident year development for the nine months ended September 30, 2025 and 2024 included a $64 and $87 benefit for amortization of a deferred gain under retroactive reinsurance accounting, respectively, related to the Navigators Adverse Development Cover (the "Navigator's ADC"). For additional information regarding the ADC reinsurance agreement, refer to "Change in Deferred Gain on Retroactive Reinsurance" discussion below.

Unfavorable (Favorable) Prior Accident Year Development

[1]The $64 and $87 change in deferred gain on retroactive reinsurance for the nine months ended September 30, 2025 and 2024, respectively, is related to amortization of the Navigators ADC deferred gain. For additional information regarding the ADC reinsurance agreement, refer to "Change in Deferred Gain on Retroactive Reinsurance" discussion below.

Re-estimates of prior accident year reserves for the nine months ended September 30, 2025

Workers’ compensation reserves were decreased within the 2016 to 2021 accident years primarily in small business, driven by lower than previously estimated claim severity.

Commercial property reserves were decreased primarily within accident years 2023 and 2024 as a result of lower than expected severity.

Professional liability reserves were decreased due to favorable development on directors and officers ("D&O") claims driven by the 2020 to 2023 accident years, partially offset by deterioration in employment practices liability and errors and omissions ("E&O") claims across multiple accident years.

Bond reserves decreased due primarily to favorable development on commercial and contract surety bonds driven by accident years 2019 to 2021.

Personal automobile liability reserves were decreased primarily within accident years 2020 to 2023 as a result of lower than expected severity.

Homeowners reserves were decreased primarily due to favorable severity impacting accident year 2024.

Catastrophes reserves were decreased across Business Insurance and Personal Insurance primarily driven by a reduction in reserves in accident years 2021 to 2024, including favorable emergence related to various hail events.

Other reserve re-estimates, net, were decreased due to lower than expected severity on Personal Insurance automobile physical damage for accident year 2024, partially offset by unfavorable development from participation in involuntary market pools.

Re-estimates of prior accident year reserves for the nine months ended September 30, 2024

Workers’ compensation reserves were decreased within the 2016 to 2020 accident years primarily in small business, driven by lower than previously estimated claim severity. In addition, the 2020 accident year includes a $48 reduction of COVID-19 related reserves driven by favorable claim count emergence.

General liability reserves were increased primarily in response to higher frequency of large losses in the 2016 to 2019 accident years as well as increases in more recent accident years, with the increase in reserves for the three months ended September 30, 2024, focused more toward the recent accident years. In addition, reserves for sexual molestation and sexual abuse claims were increased for older accident years. Lastly, reserves for extra contractual liability claims and other miscellaneous run-off lines were reduced in response to recent favorable loss activity.

Professional liability reserves decreased modestly due to favorable development on D&O claims driven by the 2020 to 2022 accident years, partially offset by deterioration in older accident years.

Bond reserves decreased due to favorable development on commercial and contract surety driven by accident years 2019 and prior.

Assumed reinsurance reserves were increased due to higher reserve estimates in the Latin America surety and Latin America P&C businesses related to the 2020 to 2023 accident years.

Automobile liability reserves - Business Insurance increased primarily due to adverse loss development within accident years 2022 and 2023 driven by higher severity than estimated.

Automobile liability reserves - Personal Insurance were decreased primarily in response to better than anticipated accident year 2023 claim severity for property damage liability.

Homeowners reserves were decreased primarily due to favorable severity impacting accident year 2023.

Catastrophes reserves were decreased primarily within Business Insurance driven by a reduction in reserves in accident years 2021 to 2022 related to favorable emergence related to

various hail events, as well as favorable development in accident year 2022 related to Hurricane Ian.

Other reserve re-estimates, net, included a decrease in reserves due to lower severity than expected on Personal Insurance automobile physical damage for accident year 2023, offset by an increase in reserves related to unfavorable development from participation in involuntary market pools.

Settlement Agreement with Boy Scouts of America

On February 14, 2022, the Company executed a final settlement agreement (the “Settlement”) with the Boy Scouts of America ("BSA"), the Local Councils, and the attorneys representing a majority of the alleged victims, pursuant to which The Hartford agreed to pay $787 for sexual molestation and sexual abuse claims associated with liability policies issued by various Hartford writing companies in the 1970s and early 1980s. In exchange for its payment, the Company receives a complete release of its policies issued to BSA and the Local Councils, as well as an injunction against further abuse claims involving BSA. All conditions precedent to the Settlement have been satisfied, including approval by the bankruptcy court and the district court, and on April 20, 2023, The Hartford paid the Settlement amount of $787. Certain objecting parties appealed the district court’s ruling. As to issues material to The Hartford’s settlement, the Third Circuit has dismissed those appeals as moot. On October 14, 2025, certain objecting parties petitioned the U.S. Supreme

Court for review. If the U.S. Supreme Court agrees to hear the case, the court approvals for the BSA’s plan of reorganization could be open to challenge, and it is possible that adverse outcomes, if any, could have a material adverse effect on the Company’s operating results.

Change in Deferred Gain on Retroactive Reinsurance

The Company has in place an ADC reinsurance agreement that covered substantially all reserve development of Navigators Insurance Company and certain of its affiliates for 2018 and prior accident years (the “Navigators ADC”) up to an aggregate limit of $300, for which the Company had previously ceded the available limit. The Company has collected recoveries from National Indemnity Company ("NICO"), a subsidiary of Berkshire Hathaway Inc., and as a result amortized $8 and $64 of the deferred gain within benefits, losses and loss adjustment expenses during the three and nine months ended September 30, 2025, respectively, and amortized $26 and $87 during the three and nine months ended September 30, 2024, respectively. As of September 30, 2025, the deferred gain on the Navigators ADC has been fully amortized. As of December 31, 2024, the deferred gain on the Navigators ADC was $64, and is included in other liabilities on the Condensed Consolidated Balance Sheets.

Group Life, Disability and Accident Products

Rollforward of Liabilities for Unpaid Losses and Loss Adjustment Expenses

[1]Prior incurral year development represents the change in estimated ultimate incurred losses and loss adjustment expenses for prior incurral years on a discounted basis.

[2]Includes unallocated loss adjustment expenses ("ULAE") of $129 and $130 for the nine months ended September 30, 2025 and 2024, respectively, that are recorded in insurance operating costs and other expenses in the Condensed Consolidated Statements of Operations.

Re-estimates of prior incurral years reserves for the nine months ended September 30, 2025

Group disability - Prior period reserve estimates decreased by approximately $403 driven by favorable long-term disability claim recoveries, paid family and medical leave incidence lower than prior assumptions, as well as a higher New York paid family leave risk adjustment benefit than expected.

Group life and accident (including group life premium waiver) - Prior period reserve estimates decreased by approximately $81 driven by favorable mortality emergence in both group term life and group accidental death and dismemberment, and continued low incidence in group life premium waiver.

Re-estimates of prior incurral years reserves for the nine months ended September 30, 2024

Group disability- Prior period reserve estimates decreased by approximately $394 largely driven by long-term disability claim incidence lower than prior assumptions and favorable recoveries on prior incurral year claims, as well as a favorable change in the recovery rate assumption.

Group life and accident (including group life premium waiver)-Prior period reserve estimates decreased by approximately $68 largely driven by favorable mortality emergence and continued low incidence in group life premium waiver.

10. Reserve for Future Policy Benefits

[1]Payout Annuities and Paid-up Life haveno expected future gross premiums.

The Company completed a review of cash flow assumptions in the third quarter 2025 and 2024, resulting in immaterial changes to the reserve for future policy benefits. For paid-up life, the net effect of updating cash flow assumptions was offset by a corresponding impact to the deferred profit liability.

Gross premiums and interest accretion recognized on long-duration insurance policies for the nine months ended September 30, 2025 and 2024 were immaterial.

11. Other Policyholder Funds and Benefits Payable

Other policyholder funds and benefits payable of $614 and $613 as of September 30, 2025 and 2024 respectively, included universal life long-duration contracts of $197 and $209 as well as policyholder balances related to short-duration contracts of

$417 and $404. The universal life long-duration contracts presented in the table below were economically ceded to Prudential as part of the sale of the Company's former individual life business, which closed in 2013.

[1]Net amount at risk is defined as the current death benefit in excess of the current account value as of the balance sheet date.

As of September 30, 2025 and 2024, universal life contracts of $196 and $208, respectively, had crediting rates at their guaranteed minimums ranging from 4%-5%.

12. Income Taxes

Income Tax Expense

Uncertain Tax Positions

The entire amount of unrecognized tax benefits, if recognized, would affect the effective tax rate in the period of the release.

Other Tax Matters

H.R.1, known as the “One Big Beautiful Bill Act” was signed into law on July 4, 2025. This comprehensive budget reconciliation package consolidates a wide array of public policy priorities, reshaping federal policy across numerous sectors of the American economy, including taxation, healthcare, social safety nets, immigration, and education. The changes in H.R.1 do not currently have a material impact on the Company's results of operations nor are they expected to in future periods.

The federal statute of limitations for the Company is closed through the 2021 tax year with the exception of the Navigators pre-acquisition 2019 tax period. Management believes that adequate provision has been made in the Company's Condensed Consolidated Financial Statements for any potential adjustments that may result from tax examinations and other tax-related matters for all open tax years.

13. Debt

Revolving Credit Facility

The Hartford has a $750 senior unsecured revolving credit facility, including $100 available to support letters of credit (the "Credit Facility"). On September 24, 2025, The Hartford amended and restated the Credit Facility, which, among other changes, extends the term of the facility through September 24, 2030. Under the Credit Facility:

•Revolving loans may be in multiple currencies.

•U.S. dollar loans will bear interest at a floating rate equivalent to an indexed rate plus a basis point spread based on The Hartford's credit rating and will mature no later than September 24, 2030.

•Letters of credit bear a fee based on The Hartford's credit rating and expire no later than September 24, 2031.

The Credit Facility requires the Company to maintain a minimum consolidated net worth financial covenant to $12.7 billion, excluding AOCI, limits the ratio of senior debt to capitalization, excluding AOCI, at 35% and includes other customary covenants. The Credit Facility is for general corporate purposes.

As of September 30, 2025 and December 31, 2024, no borrowings were outstanding, no letters of credit were issued under the Credit Facility and The Hartford wasin compliance with all financial covenants.

For further information regarding the Credit Facility, see Note 13 - Debt of Notes to Consolidated Financial Statements included in the Company's 2024 Form 10-K Annual Report.

Collateralized Advances with Federal Home Loan Bank of Boston

The Company’s subsidiaries, Hartford Fire Insurance Company (“Hartford Fire”) and Hartford Life and Accident Insurance Company ("HLA"), are members of the Federal Home Loan Bank of Boston ("FHLBB"). Membership allows these subsidiaries access to collateralized advances, which may be short- or long-term with fixed or variable rates. FHLBB membership required the purchase of member stock and requires additional member stock ownership of 3% or 4% of any amount borrowed. The amount of advances that can be taken is limited to a percentage of the fair value of the assets considered eligible collateral. In its consolidated balance sheets, The Hartford presents the liability for advances taken based on use of the funds with advances for general corporate purposes presented in short- or long-term debt and advances to earn incremental investment income presented in other liabilities, consistent with other collateralized financing transactions such as securities lending and repurchase agreements.

Prior to October 1, 2025, the Connecticut Department of Insurance permitted Hartford Fire and HLA to pledge up to $1.4 billion and $0.6 billion in qualifying assets, respectively, without prior approval, to secure FHLBB advances. The pledge limit was determined quarterly based on statutory admitted assets and capital and surplus of Hartford Fire and HLA, respectively. As of September 30, 2025 and December 31, 2024, there wereno advances outstanding under the FHLBB facility.

Effective October 1, 2025, the Company is no longer subject to the Connecticut Department of Insurance hypothecation limit or approval related to FHLBB advances. The Company’s pledge capacity is now subject to FHLB’s collateral eligibility requirements, which may be amended at their discretion. Based on these requirements, the Company estimates that Hartford Fire and HLA can each pledge up to $2 billion to secure FHLBB advances.

14. Commitments and Contingencies

Management evaluates each contingent matter separately. A loss is recorded if probable and reasonably estimable. Management establishes liabilities for these contingencies at its “best estimate,” or, if no one number within the range of possible losses is more probable than any other, the Company records an estimated liability at the low end of the range of losses.

Litigation

The Hartford is involved in claims litigation arising in the ordinary course of business, both as a liability insurer defending or providing indemnity for third-party claims brought against insureds and as an insurer defending coverage claims brought against it. The Hartford accounts for such activity through the establishment of unpaid loss and loss adjustment expense reserves. Subject to the uncertainties related to sexual molestation and sexual abuse claims, including those discussed in Note 9 - Reserve for Unpaid Losses and Loss Adjustment Expenses of this Form 10-Q and in Note 10 - Reserve for Unpaid Losses and Loss Adjustment Expenses, of the Company's Annual Report on Form 10-K for the year ended December 31, 2024, and in the following discussion under the caption “Run-off Asbestos and Environmental Claims,” management expects that the ultimate liability, if any, with respect to such ordinary-course claims litigation, after consideration of provisions made for potential losses and costs of defense, will not be material to the consolidated financial condition, results of operations or cash flows of The Hartford.

The Hartford is also involved in other kinds of legal actions, some of which assert claims for substantial amounts. In addition to the matter described below, these actions include putative class actions seeking certification of a state or national class. Such putative class actions have alleged, for example, underpayment of claims or improper sales or underwriting practices in connection with various kinds of insurance policies, such as personal and commercial automobile and property. The Hartford also is involved in individual actions in which punitive damages are sought, such as claims alleging bad faith in the

handling of insurance claims or other allegedly unfair or improper business practices. Management expects that the ultimate liability, if any, with respect to such lawsuits, after consideration of provisions made for estimated losses, will not be material to the consolidated financial condition of The Hartford. Nonetheless, given the large or indeterminate amounts sought in certain of these actions, and the inherent unpredictability of litigation, the outcome in certain matters could, from time to time, have a material adverse effect on the Company’s results of operations or cash flows in particular quarterly or annual periods.

Run-off Asbestos and Environmental Claims

The Company continues to receive A&E claims. Asbestos claims relate primarily to bodily injuries asserted by people who came in contact with asbestos or products containing asbestos. Environmental claims relate primarily to pollution and related clean-up costs.

The vast majority of the Company's exposure to A&E relates to accident years prior to 1986 that are reported in Property & Casualty Other Operations ("Run-off A&E"). In addition, since 1986, the Company has written A&E exposures under general liability policies and pollution liability under homeowners policies, which are reported in the Business Insurance and Personal Insurance segments, respectively.

Prior to 1986, the Company wrote several different categories of insurance contracts that may cover A&E claims. First, the Company wrote primary policies providing the first layer of coverage in an insured’s liability program. Second, the Company wrote excess and umbrella policies providing higher layers of coverage for losses that exhaust the limits of underlying coverage. Third, the Company acted as a reinsurer assuming a portion of those risks assumed by other insurers writing primary, excess, umbrella and reinsurance coverages.

Significant uncertainty limits the ability of insurers and reinsurers to estimate the ultimate reserves necessary for unpaid gross losses and expenses related to environmental and asbestos claims. The degree of variability of gross reserve estimates for these exposures is significantly greater than for other more traditional exposures.

In the case of the reserves for asbestos exposures, factors contributing to the high degree of uncertainty include inadequate loss development patterns, plaintiffs’ expanding theories of liability, the risks inherent in major litigation, and inconsistent and emerging legal doctrines with respect to the underlying claims and with respect to the Company's coverage obligations. Furthermore, over time, insurers, including the Company, have experienced significant changes in the rate at which asbestos claims are brought, the claims experience of particular insureds, and the value of claims, making predictions of future exposure from past experience uncertain. Plaintiffs and insureds also have sought to use bankruptcy proceedings, including “pre-packaged” bankruptcies, to accelerate and increase loss payments by insurers. In addition, some policyholders have asserted new classes of claims for coverages to which an aggregate limit of liability may not apply. Further uncertainties include insolvencies of other carriers, insolvencies of insureds and unanticipated developments pertaining to the Company’s ability to recover reinsurance for A&E claims. Management believes these issues are not likely to be resolved in the near future.

In the case of the reserves for environmental exposures, factors contributing to the high degree of uncertainty include expanding theories of liability and damages against insureds, emerging risks from products and substances alleged to cause damage, such as per-and polyfluoroalkyl substances ("PFAS"), the risks inherent in major litigation, inconsistent and emerging legal doctrines concerning the existence and scope of coverage for environmental claims, and the scope and level of complexity of the remediation required by regulators.

The reporting pattern for assumed reinsurance claims, including those related to A&E claims, is much longer than for direct claims. In many instances, it takes months or years to determine that the policyholder’s own obligations have been met and how the reinsurance in question may apply to such claims. The delay in reporting reinsurance claims and exposures adds to the uncertainty of estimating the related reserves.

It is also not possible to predict changes in the legal and legislative environment and their effect on the future development of A&E claims.

Given the factors described above, the Company believes the actuarial tools and other techniques it employs to estimate the ultimate cost of claims for more traditional kinds of insurance exposure are less precise in estimating reserves for A&E exposures. For this reason, the Company principally relies on exposure-based analysis to estimate the ultimate costs of these claims, both gross and net of reinsurance, and regularly evaluates new account information in assessing its potential A&E exposures. The Company supplements this exposure-based analysis with evaluations of the Company’s historical direct net loss and expense paid and reported experience, and net loss and expense paid and reported experience by calendar and/or report year, to assess any emerging trends, fluctuations or characteristics suggested by the aggregate paid and reported activity.

For its Run-off A&E claims, as of September 30, 2025, the Company reported $99 of net A&E reserves, including the benefit of losses ceded to the A&E ADC with NICO. In addition, the Company has recorded a $850 deferred gain within other liabilities for losses economically ceded to NICO but for which the benefit is not recognized in earnings until later periods. While the Company believes that its current Run-off A&E reserves are appropriate, significant uncertainties limit our ability to estimate the ultimate reserves necessary for unpaid losses and related expenses. The ultimate liabilities, thus, could exceed the currently recorded reserves, and any such additional liability, while not reasonably estimable now, could be material to The Hartford's consolidated operating results or liquidity.

The Company’s A&E ADC reinsurance agreement reinsures substantially all A&E reserve development for 2016 and prior accident years, including Run-off A&E and A&E reserves included in Business Insurance and Personal Insurance. The A&E ADC has a coverage limit of $1.5 billion above the Company’s existing net A&E reserves as of December 31, 2016 of approximately $1.7 billion. As of September 30, 2025, the Company has incurred $1.5 billion in cumulative adverse development on A&E reserves that have been ceded under the A&E ADC treaty, leavingno remaining coverage available for future adverse net reserve development, if any. Cumulative adverse development of A&E claims for accident years 2016 and prior in excess of the treaty limit are absorbed as a charge to earnings by the Company. The effect of future charges could be material to the Company’s consolidated operating results or liquidity. For more information on the A&E ADC, refer to Note 10 - Reserve for Unpaid Losses and Loss Adjustment Expenses of Notes to Consolidated Financial Statements included in the Company's 2024 Form 10-K Annual Report.

Derivative Commitments

Certain of the Company’s derivative agreements contain provisions that are tied to the financial strength ratings, as set by nationally recognized statistical agencies, of the individual legal entity that entered into the derivative agreement. If the legal entity’s financial strength were to fall below certain ratings, the counterparties to the derivative agreements could, in certain instances, terminate the agreements and demand immediate settlement of all outstanding derivative positions traded under each impacted bilateral agreement.

The settlement amount is determined by netting the derivative positions transacted under each agreement. If the termination rights were to be exercised by the counterparties, it could impact the legal entity’s ability to conduct hedging activities by increasing the associated costs and decreasing the willingness of counterparties to transact with the legal entity. The aggregate fair value of all derivative instruments with credit-risk-related contingent features that are in a net liability position as of September 30, 2025 was $55 for which the legal entities have posted collateral of $49 in the normal course of business. Based on derivative contractual terms as of September 30, 2025, a downgrade of the current financial strength ratings by either Moody's or S&P wouldnot require additional assets to be posted as collateral. This requirement could change as a result of changes in our hedging activities or to the extent changes in contractual terms are negotiated. The nature of the additional collateral that we would post, if required, would be primarily in the form of U.S. Treasury bills, U.S. Treasury notes and government agency securities.

15. Equity

Equity Repurchase Program

During the nine months ended September 30, 2025 and 2024, the Company repurchased $1.2 billion (9.9 million shares) and $1.1 billion (11.0 million shares), respectively, of common stock under Board authorized share repurchase programs covering the applicable periods. As of September 30, 2025, the Company has $1.95 billion remaining for equity repurchases under the current $3.3 billion share repurchase program, which is effective until December 31, 2026. During the period October 1, 2025 through October 24, 2025, the Company repurchased $131 (1.0 million common shares) under this repurchase program.

The timing of any repurchases of shares is dependent on several factors, including the market price of the Company's securities, the Company's capital position, consideration of the effect of any repurchases on the Company's financial strength or credit ratings, the Company's blackout periods, and other considerations.

17. Employee Benefit Plans

The Company’s employee benefit plans are described in Note 18 - Employee Benefit Plans of Notes to Consolidated Financial Statements included in The Hartford’s 2024 Form 10-K Annual Report. Net periodic cost (benefit) is recognized in insurance operating costs and other expenses in the Condensed Consolidated Statement of Operations.

Based on the funded status of the U.S. qualified defined benefit pension plan, the Company does not anticipate contributing to the plan in 2025.
