The Allstate Corporation 4Q24 Supplement 15

Definitions of Non-GAAP Measures We believe that investors’ understanding of Allstate’s performance is enhanced by our disclosure of the following non-GAAP measures. Our methods for calculating these measures may differ from those used by other companies and therefore comparability may be limited. Adjusted net income (loss) is net income (loss) applicable to common shareholders, excluding: • Net gains and losses on investments and derivatives • Pension and other postretirement remeasurement gains and losses • Amortization or impairment of purchased intangibles • Gain or loss on disposition • Adjustments for other significant non-recurring, infrequent or unusual items, when (a) the nature of the charge or gain is such that it is reasonably unlikely to recur within two years, or (b) there has been no similar charge or gain within the prior two years • Related income tax expense or benefit of these items Net income (loss) applicable to common shareholders is the GAAP measure that is most directly comparable to adjusted net income. We use adjusted net income as an important measure to evaluate our results of operations. We believe that the measure provides investors with a valuable measure of the Company’s ongoing performance because it reveals trends in our insurance and financial services business that may be obscured by the net effect of net gains and losses on investments and derivatives, pension and other postretirement remeasurement gains and losses, amortization or impairment of purchased intangibles, gain or loss on disposition and adjustments for other significant non-recurring, infrequent or unusual items and the related tax expense or benefit of these items. Net gains and losses on investments and derivatives, and pension and other postretirement remeasurement gains and losses may vary significantly between periods and are generally driven by business decisions and external economic developments such as capital market conditions, the timing of which is unrelated to the insurance underwriting process. Gain or loss on disposition is excluded because it is non-recurring in nature and the amortization or impairment of purchased intangibles is excluded because it relates to the acquisition purchase price and is not indicative of our underlying business results or trends. Non-recurring items are excluded because, by their nature, they are not indicative of our business or economic trends. Accordingly, adjusted net income excludes the effect of items that tend to be highly variable from period to period and highlights the results from ongoing operations and the underlying profitability of our business. A byproduct of excluding these items to determine adjusted net income is the transparency and understanding of their significance to net income variability and profitability while recognizing these or similar items may recur in subsequent periods. Adjusted net income is used by management along with the other components of net income (loss) applicable to common shareholders to assess our performance. We use adjusted measures of adjusted net income in incentive compensation. Therefore, we believe it is useful for investors to evaluate net income (loss) applicable to common shareholders, adjusted net income and their components separately and in the aggregate when reviewing and evaluating our performance. We note that investors, financial analysts, financial and business media organizations and rating agencies utilize adjusted net income results in their evaluation of our and our industry’s financial performance and in their investment decisions, recommendations and communications as it represents a reliable, representative and consistent measurement of the industry and the Company and management’s performance. We note that the price to earnings multiple commonly used by insurance investors as a forward-looking valuation technique uses adjusted net income as the denominator. Adjusted net income should not be considered a substitute for net income (loss) applicable to common shareholders and does not reflect the overall profitability of our business. A reconciliation of adjusted net income to net income (loss) applicable to common shareholders is provided in the schedule, "Contribution to Income". Underlying loss ratio is a non-GAAP ratio, which is computed as the difference between three GAAP operating ratios: the loss ratio, the effect of catastrophes on the combined ratio, and the effect of prior year non-catastrophe reserve reestimates on the combined ratio. We believe that this ratio is useful to investors, and it is used by management to reveal the trends that may be obscured by catastrophe losses and prior year reserve reestimates. Catastrophe losses cause our loss trends to vary significantly between periods as a result of their incidence of occurrence and magnitude, and can have a significant impact on the combined ratio. Prior year reserve reestimates are caused by unexpected loss development on historical reserves. We believe it is useful for investors to evaluate these components separately and in the aggregate when reviewing our underwriting performance. The most directly comparable GAAP measure is the loss ratio. The underlying loss ratio should not be considered a substitute for the loss ratio and does not reflect the overall loss ratio of our business. A reconciliation of underlying loss ratio is provided in the schedules "Property-Liability Results", "Allstate Protection Profitability Measures", "Auto Profitability Measures" and "Homeowners Profitability Measures". Underlying expense ratio is a non-GAAP ratio, which is computed as the difference between the expense ratio and the effect of amortization or impairment of purchased intangibles on the expense ratio. We believe that the measure provides investors with a valuable measure of ongoing performance because it reveals trends that may be obscured by the amortization or impairment of purchased intangible assets. Amortization or Impairment of purchased intangible assets is excluded because it relates to the acquisition purchase price and is not indicative of our business results or trends. We believe it is useful for investors to evaluate these components separately and in the aggregate when reviewing our underwriting performance. The most directly comparable GAAP measure is the expense ratio. The underlying expense ratio should not be considered a substitute for the expense ratio and does not reflect the overall expense ratio of our business. A reconciliation of underlying expense ratio is provided in the schedules "Property-Liability Results", "Allstate Protection Profitability Measures", "Auto Profitability Measures" and "Homeowners Profitability Measures". Average underlying loss (incurred pure premium) and average underlying loss (incurred pure premium) and expense per policy are calculated as the underlying loss ratio and the underlying combined ratio (non-GAAP ratios), respectively, multiplied by the annualized GAAP earned premium ("annualized average earned premium”). We believe that these measures are useful to investors and are used by management for the same reasons noted above for the underlying loss and underlying combined ratios. The components of the calculation are available on the "Auto Profitability Measures and Statistics" page. The Allstate Corporation 4Q24 Supplement 16

Definitions of Non-GAAP Measures (continued) Adjusted underwriting expense ratio is a non-GAAP ratio, which is computed as the difference between the expense ratio and the effect of advertising expense, restructuring and related charges and amortization or impairment of purchased intangibles on the expense ratio. We believe that the measure provides investors with a valuable measure of ongoing performance because it reveals trends that may be obscured by the advertising expense, restructuring and related charges and amortization or impairment of purchased intangibles. Advertising expense is excluded as it may vary significantly from period to period based on business decisions and competitive position. Restructuring and related charges are excluded because these items are not indicative of our business results or trends. Amortization or impairment of purchased intangible assets is excluded because it relates to the acquisition purchase price. These are not indicative of our business results or trends. A reduction in expenses enables investment flexibility that can drive growth. We believe it is useful for investors to evaluate these components separately and in the aggregate when reviewing our underwriting performance. The most directly comparable GAAP measure is the expense ratio. The adjusted underwriting expense ratio should not be considered a substitute for the expense ratio and does not reflect the overall expense ratio of our business. Adjusted expense ratio is a non-GAAP ratio, which is computed as the combination of the adjusted underwriting expense ratio and claims expense ratio excluding catastrophe expense. We believe it is useful for investors to evaluate this ratio which is linked to a long-term expense ratio improvement commitment through 2024. The most directly comparable GAAP measure is the expense ratio. The adjusted expense ratio should not be considered a substitute for the expense ratio and does not reflect the overall expense ratio of our business. Underlying combined ratio is a non-GAAP ratio, which is the sum of the underlying loss and underlying expense ratios. We believe that this ratio is useful to investors, and it is used by management to reveal the trends in our Property-Liability business that may be obscured by catastrophe losses, prior year reserve reestimates and amortization or impairment of purchased intangibles. We believe it is useful for investors to evaluate these components separately and in the aggregate when reviewing our underwriting performance. The most directly comparable GAAP measure is the combined ratio. The underlying combined ratio should not be considered a substitute for the combined ratio and does not reflect the overall underwriting profitability of our business. A reconciliation of the underlying combined ratio to combined ratio is provided in the schedule "Property-Liability Results", "Auto Profitability Measures" and "Homeowners Profitability Measures". Protection Services adjusted earnings before taxes, depreciation and restructuring, is a non-GAAP measure, which is computed as adjusted net income (loss), excluding taxes, depreciation and restructuring. Adjusted net income (loss) is the GAAP measure that is most directly comparable to adjusted earnings before taxes, depreciation and restructuring. We use adjusted earnings before taxes, depreciation and restructuring, as an important measure to evaluate Protection Services' results of operations. We believe that the measure provides investors with a valuable measure of Protection Services' ongoing performance because it reveals trends that may be obscured by the taxes, depreciation and restructuring expenses. Taxes, depreciation and restructuring are excluded because these are not directly attributable to the underlying operating performance of Protection Services' segment. Adjusted earnings before taxes, depreciation and restructuring highlights the results from ongoing operations and the underlying profitability of our business and is used by management along with the other components of adjusted net income (loss) to assess our performance. We believe it is useful for investors to evaluate adjusted net income (loss), adjusted earnings before taxes, depreciation and restructuring, and their components separately and in the aggregate when reviewing and evaluating Protection Services segment’s performance. Adjusted earnings before taxes, depreciation and restructuring should not be considered a substitute for adjusted net income (loss) and does not reflect the overall profitability of our business. A reconciliation of adjusted net income (loss) to adjusted earnings before taxes, depreciation and restructuring, is provided in the schedule, "Protection Services Segment Results". Adjusted net income (loss) return on Allstate common shareholders’ equity is a ratio that uses a non-GAAP measure. It is calculated by dividing the rolling 12-month adjusted net income by the average of Allstate common shareholders’ equity at the beginning and at the end of the 12-months, after excluding the effect of unrealized net capital gains and losses. Return on Allstate common shareholders’ equity is the most directly comparable GAAP measure. We use adjusted net income as the numerator for the same reasons we use adjusted net income, as discussed previously. We use average Allstate common shareholders’ equity excluding the effect of unrealized net capital gains and losses for the denominator as a representation of common shareholders’ equity primarily applicable to Allstate's earned and realized business operations because it eliminates the effect of items that are unrealized and vary significantly between periods due to external economic developments such as capital market conditions like changes in equity prices and interest rates, the amount and timing of which are unrelated to the insurance underwriting process. We use it to supplement our evaluation of net income (loss) applicable to common shareholders and return on Allstate common shareholders’ equity because it excludes the effect of items that tend to be highly variable from period to period. We believe that this measure is useful to investors and that it provides a valuable tool for investors when considered along with return on Allstate common shareholders’ equity because it eliminates the after-tax effects of realized and unrealized net capital gains and losses that can fluctuate significantly from period to period and that are driven by economic developments, the magnitude and timing of which are generally not influenced by management. In addition, it eliminates non-recurring items that are not indicative of our ongoing business or economic trends. A byproduct of excluding the items noted above to determine adjusted net income return on Allstate common shareholders’ equity from return on Allstate common shareholders’ equity is the transparency and understanding of their significance to return on common shareholders’ equity variability and profitability while recognizing these or similar items may recur in subsequent periods. We use adjusted measures of adjusted net income return on Allstate common shareholders’ equity in incentive compensation. Therefore, we believe it is useful for investors to have adjusted net income return on Allstate common shareholders’ equity and return on Allstate common shareholders’ equity when evaluating our performance. We note that investors, financial analysts, financial and business media organizations and rating agencies utilize adjusted net income return on common shareholders’ equity results in their evaluation of our and our industry’s financial performance and in their investment decisions, recommendations and communications as it represents a reliable, representative and consistent measurement of the industry and the company and management’s utilization of capital. Adjusted net income return on Allstate common shareholders’ equity should not be considered a substitute for return on Allstate common shareholders’ equity and does not reflect the overall profitability of our business. A reconciliation of return on Allstate common shareholders' equity and adjusted net income return on Allstate common shareholders' equity can be found in the schedule, "Return on Allstate Common Shareholders' Equity". Book value per common share, excluding the impact of unrealized net capital gains and losses on fixed income securities, is a ratio that uses a non-GAAP measure. It is calculated by dividing Allstate common shareholders’ equity after excluding the impact of unrealized net capital gains and losses on fixed income securities by total common shares outstanding plus dilutive potential common shares outstanding. We use the trend in book value per common share, excluding the impact of unrealized net capital gains and losses on fixed income securities, in conjunction with book value per common share to identify and analyze the change in net worth applicable to management efforts between periods. We believe the non-GAAP ratio is useful to investors because it eliminates the effect of items that can fluctuate significantly from period to period and are generally driven by economic developments, primarily capital market conditions, the magnitude and timing of which are generally not influenced by management, and we believe it enhances understanding and comparability of performance by highlighting underlying business activity and profitability drivers. We note that book value per common share, excluding the impact of unrealized net capital gains and losses on fixed income securities, is a measure commonly used by insurance investors as a valuation technique. Book value per common share is the most directly comparable GAAP measure. Book value per common share, excluding the impact of unrealized net capital gains and losses on fixed income securities, should not be considered a substitute for book value per common share, and does not reflect the recorded net worth of our business. A reconciliation of book value per common share, excluding the impact of unrealized net capital gains on fixed income securities, and book value per common share can be found in the schedule, "Book Value per Common Share and Debt to Capital".

Glossary Consolidated Operations Accident and health insurance premiums and contract charges are reported in the Allstate Health and Benefits segment and include employer voluntary benefits, group health and individual health products. Adjusted net income is the GAAP segment measure used for the Protection Services, Allstate Health and Benefits, and Corporate and Other segments. Average Allstate common shareholders' equity and average adjusted Allstate common shareholders' equity are determined using a two-point average, with the beginning and ending Allstate common shareholders' equity and Allstate adjusted common shareholders' equity, respectively, for the twelve-month period as data points. Other revenue primarily represents fees collected from policyholders relating to premium installment payments, commissions on sales of non-proprietary products, sales of identity protection services, fee-based services and other revenue transactions. Property and casualty insurance premiums are reported in the Allstate Protection and Protection Services segments and include auto, homeowners, other personal lines, commercial lines and other business lines insurance products, as well as consumer product protection plans, roadside assistance and automotive protection and insurance products. Property-Liability Annualized average earned premium is calculated by annualizing net earned premium reported in the quarter and year-to-date divided by policies in force at quarter end. Average premium - gross written: Gross premiums written divided by issued item count. Gross premiums written include the impacts from discounts, surcharges and ceded reinsurance premiums and exclude the impacts from mid- term premium adjustments and premium refund accruals. Average premiums represent the appropriate policy term for each line, which is generally 6 months for auto and 12 months for homeowners. Claims expense ratio excluding catastrophe expense: Incurred loss adjustment expenses, net of reinsurance, excluding expenses related to catastrophes. These expenses are embedded within the loss ratio. Expense ratio: Other revenue is deducted from other costs and expenses in the expense ratio calculation. New issued applications: Item counts of automobile and homeowner insurance applications for insurance policies that were issued during the period, regardless of whether the customer was previously insured by another Allstate Protection brand. Other business lines primarily represent commissions earned and other costs and expenses for Ivantage, non-proprietary life and annuity products, and lender-placed products. Protection Services Other costs and expenses may include amortization of deferred policy acquisition costs, operating costs and expenses, and restructuring and related charges. Revenue may include net premiums earned, intersegment insurance premiums and service fees, other revenue, revenue earned from external customers and net investment income. Allstate Health and Benefits Benefit ratio is accident, health and other policy benefits less interest credited to contractholder funds, divided by premiums and contract charges. Employer voluntary benefits includes supplemental life and health products offered through workplace enrollment. Group health includes health products and administrative services sold to employers. Individual health includes short-term medical and other health products sold directly to individuals. Investments Duration measures the price sensitivity of assets and liabilities to changes in interest rates. Equity securities include investments in exchange traded and mutual funds whose underlying investments are fixed income securities. Interest-bearing investments comprise fixed income securities, mortgage loans, short-term investments, and other investments including bank loans and derivatives. Internal rate of return is one of the measures we use to evaluate the performance of these investments. The IRR represents the rate of return on the investments considering the cash flows paid and received and, until the investment is fully liquidated, the estimated value of investment holdings at the end of the measurement period. The calculated IRR for any measurement period is highly influenced by the values of the portfolio at the beginning and end of the period, which reflect the estimated fair values of the investments as of such dates. As a result, the IRR can vary significantly for different measurement periods based on macroeconomic or other events that impact the estimated beginning or ending portfolio value, such as the global financial crisis. Our IRR calculation method may differ from those used by other investors. The timing of the recognition of income in the financial statements may differ significantly from the cash distributions and changes in the value of these investments. Limited partnership interests: Income from equity method of accounting LP is generally recognized on a three-month delay due to the availability of the investee financial statements. LP and other investments comprise limited partnership interests and other alternative investments, including real estate investments classified as other investments. Market-based investments include publicly traded equity securities classified as limited partnerships. Market-based strategy seeks to deliver predictable earnings aligned to business needs and take advantage of short-term opportunities primarily through public and private fixed income investments and public equity securities. Performance-based strategy seeks to deliver attractive risk-adjusted returns and supplement market risk with idiosyncratic risk primarily through investments in private equity, including infrastructure investments, and real estate, most of which were limited partnerships. Pre-tax yields: Quarterly pre-tax yield is calculated as annualized quarterly investment income, before investment expense divided by the average of the ending investment balances of the current and prior quarter. Year-to-date pre- tax yield is calculated as annualized year-to-date investment income, before investment expense divided by the average of investment balances at the beginning of the year and the end of each quarter during the year. For the purposes of the pre-tax yield calculation, income for directly held real estate and other investments is net of investee level expenses (asset level operating expenses reported in investment expense). Fixed income securities investment balances exclude unrealized capital gains and losses. Equity securities investment balances use cost in the calculation. Total return on investment portfolio is calculated from GAAP results, including the total of net investment income, net gains and losses on investments and derivative instruments, the change in unrealized net capital gains and losses, and the change in the difference between fair value and carrying value of mortgage and bank loans divided by the average fair value balances.
