HARTFORD INSURANCE GROUP, INC.

The Company considers the measures and ratios in the following discussion to be key performance indicators for its businesses. Management believes that these ratios and measures are useful in understanding the underlying trends in The Hartford’s businesses. However, these key performance indicators should only be used in conjunction with, and not in lieu of, the results presented in the reportable segment and corporate operating summaries that follow in this MD&A. These ratios and measures may not be comparable to other performance measures used by the Company’s competitors.

Definitions of Non-GAAP and Other Measures and Ratios

Assets Under Management ("AUM")- Include mutual fund and exchange-traded fund ("ETF") assets. AUM is a measure used by the Company's Hartford Funds segment because a significant portion of the segment’s revenues and expenses are based upon asset values. These revenues and expenses increase or decrease with a rise or fall in AUM whether caused by changes in the market or through net flows.

Book Value per Diluted Share excluding accumulated other comprehensive income ("AOCI")-This is a non-GAAP per share measure that is calculated by dividing (a) common stockholders' equity, excluding AOCI, after tax, by (b) common shares outstanding and dilutive potential common shares. The Company provides this measure to enable investors to analyze the amount of the Company's net worth that is primarily attributable to the Company's business operations. The Company believes that excluding AOCI from the numerator is useful to investors because it eliminates the effect of items that can fluctuate significantly from period to period, primarily based on changes in interest rates. Book value per diluted share is the most directly comparable U.S. GAAP measure.

Combined Ratio-The sum of the loss and loss adjustment expense ("LAE") ratio, the expense ratio and the policyholder dividend ratio. This ratio is a relative measurement that describes the related cost of losses and expenses for every $100 of earned premiums. A combined ratio below 100 demonstrates underwriting profit; a combined ratio above 100 demonstrates underwriting losses.

Core Earnings- The Hartford uses the non-GAAP measure core earnings as an important measure of the Company’s operating performance. The Hartford believes that core earnings provides investors with a valuable measure of the performance of the Company’s ongoing businesses because it reveals trends in our insurance and financial services businesses that may be obscured by including the net effect of certain items. Therefore, the following items are excluded from core earnings:

•Certain realized gains and losses - Generally realized gains and losses are primarily driven by investment decisions and external economic developments, the nature and timing of which are unrelated to the insurance and underwriting aspects of our business. Accordingly, core earnings excludes the effect of all realized gains and losses that tend to be highly variable from period to period based on capital market conditions. The Hartford believes, however, that some realized gains and losses are integrally related to our insurance operations, so core earnings includes net realized gains and losses such as net periodic settlements on credit derivatives. These net realized gains and losses are directly related to an offsetting item included in the income statement such as net investment income.

•Restructuring and other costs - Costs incurred as part of a restructuring plan are not a recurring operating expense of the business.

•Loss on extinguishment of debt - Largely consisting of make-whole payments or tender premiums upon paying debt off before maturity, these losses are not a recurring operating expense of the business.

•Gains and losses on reinsurance transactions - Gains or losses on reinsurance, such as those entered into upon sale of a business or to reinsure loss reserves, are not a recurring operating expense of the business.

•Integration and other non-recurring M&A costs - These costs, including transaction costs incurred in connection with an acquired business, are incurred over a short period of time and do not represent an ongoing operating expense of the business.

•Change in loss reserves upon acquisition of a business - These changes in loss reserves are excluded from core earnings because such changes could obscure the ability to compare results in periods after the acquisition to results of periods prior to the acquisition.

•Deferred gain resulting from retroactive reinsurance and subsequent changes in the deferred gain - Retroactive reinsurance agreements economically transfer risk to the reinsurers and excluding the deferred gain on retroactive reinsurance and related amortization of the deferred gain from core earnings provides greater insight into the economics of the business.

•Change in valuation allowance on deferred taxes related to non-core components of before tax income - These changes in valuation allowances are excluded from core earnings because they relate to non-core components of before tax income, such as tax attributes like capital loss carryforwards.

•Results of discontinued operations - These results are excluded from core earnings for businesses sold or held for sale because such results could obscure the ability to compare period over period results for our ongoing businesses.

In addition to the above components of net income available to common stockholders that are excluded from core earnings, preferred stock dividends declared, which are excluded from net income, are included in the determination of core earnings. Preferred stock dividends are a cost of financing more akin to interest expense on debt and are expected to be a recurring expense as long as the preferred stock is outstanding.

Net income (loss) and net income (loss) available to common stockholders are the most directly comparable U.S. GAAP measures to core earnings. Core earnings should not be considered as a substitute for net income (loss) or net income (loss) available to common stockholders and does not reflect the overall profitability of the Company’s business. Therefore, The Hartford believes that it is useful for investors to evaluate net income (loss), net income (loss) available to common stockholders, and core earnings when reviewing the Company’s performance.

[1]The Company recorded amortization of the deferred gain related to the Navigators adverse development cover ("Navigators ADC") of $8 and $64 for the three and nine months ended September 30, 2025 and $26 and $87 for the three and nine months ended September 30, 2024, respectively. The deferred gain has been fully amortized as of September 30, 2025. For additional information regarding the ADC reinsurance agreement, refer to Note 9 - Reserve for Unpaid Losses and Loss Adjustment Expenses of Notes to Condensed Consolidated Financial Statements.

[2]Primarily represents the federal income tax expense (benefit) related to before tax items not included in core earnings.

Core Earnings Margin- The Hartford uses the non-GAAP measure core earnings margin to evaluate, and believes it is an important measure of, the Employee Benefits segment's operating performance. Core earnings margin is calculated by dividing core earnings by revenues, excluding buyouts and realized gains (losses). Net income margin, calculated by dividing net income by revenues, is the most directly comparable U.S. GAAP measure. The Company believes that core earnings margin provides investors with a valuable measure of the performance of Employee Benefits because it reveals trends in the business that may be obscured by the effect of buyouts and realized gains (losses) as well as other items excluded in the calculation of core earnings. Core earnings margin should not be considered as a substitute for net income margin and does not reflect the overall profitability of Employee Benefits. Therefore, the Company believes it is important for investors to evaluate both core earnings margin and net income margin when reviewing performance. A reconciliation of net income margin to core earnings margin is set forth in the Results of Operations section within MD&A - Employee Benefits.

Current Accident Year Catastrophe Ratio-A component of the loss and loss adjustment expense ratio, represents the ratio of catastrophe losses incurred in the current accident year ("CAY") (net of reinsurance) to earned premiums. For U.S. events, a catastrophe is an event that causes $25 or more in industry insured property losses and affects a significant number of property and casualty policyholders and insurers, as defined by the Property Claim Services office of Verisk. For international events, the Company's approach is similar, informed, in part, by how Lloyd's of London defines major losses. Lloyd's of London is an insurance market-place operating worldwide ("Lloyd's"). Lloyd's does not underwrite risks. The Company accepts risks as the sole member of Lloyd's Syndicate 1221 ("Lloyd's Syndicate"). The current accident year catastrophe ratio includes the effect of catastrophe losses, but does not include the effect of reinstatement premiums.

Expense Ratio-For Business Insurance and Personal Insurance is the ratio of underwriting expenses less fee income, to earned premiums. Underwriting expenses include the amortization of deferred policy acquisition costs ("DAC"), amortization of other intangible assets and insurance operating costs and other expenses, including certain centralized services costs and bad debt expense. DAC includes commissions, taxes, licenses and fees and other incremental direct underwriting expenses and are amortized over the policy term.

The expense ratio for Employee Benefits is expressed as the ratio of insurance operating costs and other expenses including amortization of intangibles and amortization of DAC, to premiums and other considerations, excluding buyout premiums.

The expense ratio for Business Insurance, Personal Insurance and Employee Benefits does not include integration and other transaction costs associated with an acquired business.

Fee Income-Is largely driven from amounts earned as a result of contractually defined percentages of AUM in our Hartford Funds business. These fees are generally earned on a daily basis. Therefore, this fee income increases or decreases with the rise or fall in AUM whether caused by changes in the market or through net flows.

Gross New Business Premium-Represents the amount of premiums charged, before ceded reinsurance, for policies issued to customers who were not insured with the Company in the previous policy term. Gross new business premium plus gross renewal written premium less ceded reinsurance equals total written premium.

Loss and Loss Adjustment Expense Ratio-A measure of the cost of claims incurred in the calendar year divided by earned premium and includes losses and loss adjustment expenses incurred for both the current and prior accident years. Among other factors, the loss and loss adjustment expense ratio needed for the Company to achieve its targeted return on equity ("ROE") fluctuates from year to year based on changes in the expected investment yield over the claim settlement period, the timing of expected claim settlements and the targeted returns set by management based on the competitive environment.

The loss and loss adjustment expense ratio is affected by claim frequency and claim severity, particularly for shorter-tail property lines of business, where the emergence of claim frequency and severity is credible and likely indicative of ultimate losses. Claim frequency represents the percentage change in the average number of reported claims per unit of exposure in the current accident year compared to that of the previous accident year. Claim severity represents the percentage change in the estimated average cost per claim in the current accident year compared to that of the previous accident year. As one of the factors used to determine pricing, the Company’s practice is to first make an overall assumption about claim frequency and severity for a given line of business and then, as part of the rate-making process, adjust the assumption as appropriate for the particular state, product or coverage.

Underlying Loss and Loss Adjustment Expense Ratio-This non-GAAP financial measure is the cost of non-catastrophe loss and loss adjustment expenses incurred in the current accident year divided by earned premiums. The loss and loss adjustment expense ratio is the most directly comparable U.S GAAP measure. Management believes that the underlying loss and loss adjustment expense ratio is a performance measure that is useful to investors as it removes the impact of volatile and unpredictable catastrophe losses and prior accident year development ("PYD"). A reconciliation of the loss and loss adjustment expense ratio to the underlying loss and loss adjustment expense ratio is set forth in the Reportable Segment and Corporate Operating Summaries section within MD&A.

Loss Ratio, excluding Buyouts-Utilized for the Employee Benefits segment and is expressed as a ratio of benefits, losses and loss adjustment expenses, excluding those related to buyout premiums, to premiums and other considerations, excluding buyout premiums. Since Employee Benefits occasionally buys a block of claims for a stated premium amount, the Company excludes this buyout from the loss ratio used for evaluating the profitability of the business as buyouts may distort the loss ratio. Buyout premiums represent takeover of open claim liabilities and other non-recurring premium amounts.

Net investment income excluding limited partnerships and other alternative investments- This non-GAAP measure is the amount of net investment income on a consolidated level earned from invested assets, excluding the net investment income related to limited partnerships and other alternative investments. The Company believes that net investment income excluding limited partnerships and other alternative investments, provides investors with an important measure of the trend in investment

earnings because it excludes the impact of the volatility in returns related to limited partnerships and other alternative investments. Net investment income is the most directly comparable U.S. GAAP measure. A reconciliation of net investment income to net investment income excluding limited partnerships and other alternative investments - is set forth in the Investment Results section within MD&A.

Mutual Fund and Exchange-Traded Fund Assets-Are owned by the shareowners of those products and not by the Company and, therefore, are not reflected in the Company’s Condensed Consolidated Financial Statements, except in instances where the Company seeds new investment products.

Mutual fund and ETF assets are a measure used by the Company primarily because a significant portion of the Company’s Hartford Funds segment revenues and expenses are based upon asset values. These revenues and expenses increase or decrease with a rise or fall in AUM whether caused by changes in the market or through net flows.

Net New Business Premium-Represents the amount of premiums charged, after ceded reinsurance, for policies issued to customers who were not insured with the Company in the previous policy term. Net new business premium plus renewal written premium equals total written premium.

Policy Count Retention-For small business, represents the number of renewal policies issued during the current year period divided by the new and renewal policies issued in the prior period. Policy count retention is affected by a number of factors, including the percentage of renewal policy quotes accepted and decisions by the Company to non-renew policies because of specific policy underwriting concerns or because of a decision to reduce premium writings in certain classes of business or states. Policy count retention is also affected by advertising and rate actions taken by us and competitors.

Effective Policy Count Retention-For Personal Insurance, represents the number of policies expected to renew in the current year period, based on contract effective dates, divided by the new and renewal policies effective in the prior period. Effective policy count retention is affected by a number of factors, including the percentage of renewal policy quotes accepted and decisions by the Company to non-renew policies because of specific policy underwriting concerns or because of a decision to reduce premium writings in certain classes of business or states. Effective policy count retention is also affected by advertising and rate actions taken by us and competitors, as well as the effect of subsequent cancellations and non-renewals by customers. Effective policy count retention statistics are subject to change from period to period based on the effect of differences between actual and expected policy cancellations throughout the policy period.

Policies in-force- Represents the number of policies with coverage in effect as of the end of the period. The number of policies in-force is a growth measure used for Personal Insurance, small business, and middle market lines within middle & large business and is affected by both new business growth and retention.

Policyholder Dividend Ratio- The ratio of policyholder dividends to earned premium.

Premium Retention- For middle & large business, represents the ratio of prior period premiums that were successfully renewed divided by premiums associated with policies available for renewal in the current period. Premium retention excludes premium amounts from annual audits, renewal written price increases and changes in exposure, including amount of insurance. Premium retention statistics are subject to change from period to period based on a number of factors, including the effect of subsequent cancellations and non-renewals.

Prior Accident Year Loss and Loss Adjustment Expense Ratio- Represents the increase (decrease) in the estimated cost of settling catastrophe and non-catastrophe claims incurred in prior accident years as recorded in the current calendar year divided by earned premiums.

Reinstatement Premiums- Represents additional ceded premium paid for the reinstatement of the amount of reinsurance coverage that was reduced as a result of the Company ceding losses to reinsurers.

Renewal Earned Price Increase (Decrease)-Written premiums are earned over the policy term, which is six months for certain personal automobile business and twelve months for substantially all of the remainder of the Company’s Property and Casualty ("P&C") business. Since the Company earns premiums over the six to twelve month term of the policies, renewal earned price increases (decreases) lag renewal written price increases (decreases) by six to twelve months.

Renewal Written Price Increase (Decrease)-For Business Insurance, represents the combined effect of rate changes, and individual risk pricing decisions per unit of exposure on policies that renewed and includes amount of insurance. For Personal Insurance, renewal written price increases represent the total change in premium per policy since the prior year on those policies that renewed and includes the combined effect of rate changes, amount of insurance and other changes in exposure. For Personal Insurance, other changes in exposure include, but are not limited to, the effect of changes in number of drivers, vehicles and incidents, as well as changes in customer policy elections, such as deductibles and limits. The rate component represents the change in rate impacting renewal policies as previously filed with and approved by state regulators during the period. Amount of insurance represents the change in the value of the rating base, such as model year/vehicle symbol for automobiles, building replacement costs for property and wage inflation for workers’ compensation. A number of factors affect renewal written price increases (decreases) including expected loss costs as projected by the Company’s pricing actuaries, rate filings approved by state regulators, risk selection decisions made by the Company’s underwriters and marketplace competition. Renewal written price changes reflect the property and casualty insurance market cycle. Prices tend to increase for a particular line of business when insurance carriers have incurred significant losses in that line of business in the recent past or the industry as a whole commits less of its capital to writing exposures in that line of business. Prices tend to decrease when recent loss experience has been favorable or when competition among insurance carriers increases. Renewal written price

statistics are subject to change from period to period, based on a number of factors, including changes in actuarial estimates and the effect of subsequent cancellations and non-renewals, and modifications made to better reflect ultimate pricing achieved.

Return on Assets (“ROA”), Core Earnings-The Company uses this non-GAAP financial measure to evaluate, and believes is an important measure of, the Hartford Funds segment’s operating performance. ROA, core earnings is calculated by dividing annualized core earnings by a daily average AUM. ROA is the most directly comparable U.S. GAAP measure. The Company believes that ROA, core earnings, provides investors with a valuable measure of the performance of the Hartford Funds segment because it reveals trends in our business that may be obscured by the effect of items excluded in the calculation of core earnings. ROA, core earnings, should not be considered as a substitute for ROA and does not reflect the overall profitability of our Hartford Funds business. Therefore, the Company believes it is important for investors to evaluate both ROA, and ROA, core earnings when reviewing the Hartford Funds segment performance. A reconciliation of ROA to ROA, core earnings is set forth in the Results of Operations section within MD&A - Hartford Funds.

Underlying Combined Ratio-This non-GAAP financial measure of underwriting results represents the combined ratio before catastrophes, prior accident year development and current accident year change in loss reserves upon acquisition of a business. Combined ratio is the most directly comparable U.S. GAAP measure. The Company believes this ratio is an important measure of the trend in profitability since it removes the impact of volatile and unpredictable catastrophe losses and prior accident year loss and loss adjustment expense reserve development. The changes to loss reserves upon acquisition of a business are excluded from underlying combined ratio because such changes could obscure the ability to compare results in periods after the acquisition to results of periods prior to the acquisition as such trends are valuable to our investors' ability to assess the Company's financial performance.

A reconciliation of combined ratio to underlying combined ratio is set forth in the Results of Operations section within MD&A - Business Insurance and Personal Insurance.

Underwriting Gain (Loss)-This non-GAAP financial measure is a before tax measure that represents earned premiums less incurred losses, loss adjustment expenses and underwriting expenses. Net income (loss) is the most directly comparable U.S. GAAP measure. The Hartford's management evaluates profitability of the Business and Personal Insurance segments primarily on the basis of underwriting gain or loss. Underwriting gain (loss) is influenced significantly by earned premium growth and the adequacy of The Hartford's pricing. Underwriting profitability over time is also greatly influenced by The Hartford's underwriting discipline, as management strives to manage exposure to loss through favorable risk selection and diversification, effective management of claims, use of reinsurance and its ability to manage its expenses. The Hartford believes that underwriting gain (loss) provides investors with a valuable measure of profitability, before tax, derived from underwriting activities, which are managed separately from the Company's investing activities.

Written and Earned Premiums-Written premium represents the amount of premiums charged for policies issued, net of reinsurance, during a fiscal period. Premiums are considered earned and are included in the financial results on a pro rata basis over the policy period. Management believes that written premium is a performance measure that is useful to investors as it reflects current trends in the Company’s sale of property and casualty insurance products. Written and earned premium are recorded net of ceded reinsurance premium.

Traditional life and disability insurance type products, such as those sold by Employee Benefits, collect premiums from policyholders in exchange for financial protection for the policyholder from a specified insurable loss, such as death or disability. These premiums together with net investment income earned are used to pay the contractual obligations under these insurance contracts. Two major factors, sales and persistency, impact premium growth. Sales can increase or decrease in a given year based on a number of factors, including but not limited to, customer demand for the Company’s product offerings, pricing competition, distribution channels and the Company’s reputation and ratings. Persistency refers to the percentage of premium remaining in-force from year-to-year.
