Basis of presentation

The accompanying condensed consolidated financial statements include the accounts of The Allstate Corporation (the “Corporation”) and its wholly owned subsidiaries, primarily Allstate Insurance Company (“AIC”), a property and casualty insurance company (collectively referred to as the “Company” or “Allstate”) and variable interest entities (“VIEs”) in which the Company is considered a primary beneficiary. These condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”).

The condensed consolidated financial statements and notes as of September 30, 2025 and for the three and nine month periods ended September 30, 2025 and 2024 are unaudited. The condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring accruals) which are, in the opinion of management, necessary for the fair presentation of the financial position, results of operations and cash flows for the interim periods.

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 annual report on Form 10-K for the year ended December 31, 2024. The results of operations for the interim periods should not be considered indicative of results to be expected for the full year. All significant intercompany accounts and transactions have been eliminated. Certain amounts have been reclassified to conform to current year presentation.

Adopted accounting standard

Accounting for joint ventures Effective January 1, 2025, the Company adopted the new Financial Accounting Standards Board (“FASB”) guidance requiring a joint venture to initially measure assets contributed and liabilities assumed at fair value as of the formation date. The adoption had no impact on the Company’s Condensed Consolidated Statements of Operations and Condensed Consolidated Statements of Financial Position.

Pending accounting standards

Income tax disclosures In December 2023, the FASB issued guidance enhancing various aspects of income tax disclosures. The guidance requires a tabular reconciliation between statutory and effective income tax expense (benefit) with both amounts and percentages for a list of required categories. For certain required categories where an individual category is at least five percent of the statutory tax amount, the required category must be further broken out by nature and, for foreign tax effects, jurisdiction. Additionally, entities must disclose income taxes paid,

net of refunds received, broken out between federal, state and foreign, and amounts paid, net of refunds received, to an individual jurisdiction when it is five percent or more of the total income taxes paid, net of refunds received.

All requirements in the guidance are annual in nature, and the guidance is effective for annual reporting periods beginning after December 15, 2024, with early adoption permitted. The guidance affects disclosures only.

Disaggregated income statement disclosures In November 2024, the FASB issued guidance requiring disaggregated information about specific expense categories included in certain income statement expense line items. The guidance outlines the specific costs that are required to be disclosed, which include costs such as: employee compensation, depreciation, intangible asset amortization and selling costs. It also requires qualitative descriptions of the amounts remaining in the relevant income statement captions that are not separately disaggregated quantitatively in the notes to the financial statements and the Company's definition of selling expenses.

The new guidance is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, with early adoption permitted. The standard is effective on a prospective basis, with the option for retrospective application. The guidance affects disclosures only.

Credit losses In July 2025, the FASB issued guidance providing a practical expedient for estimating credit losses on current accounts receivable and contract assets arising from revenue transactions under ASC 606. The update now allows entities to assume current conditions remain unchanged for the asset's remaining life when estimating expected credit losses, simplifying the estimation process.

The new guidance is effective for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods, with early adoption permitted. The Company does not expect the impact of this standard to be material to its financial statements and disclosures.

Internal-use software In September 2025, the FASB issued guidance which updates the accounting for internal-use software by replacing the stage-based model with a principles-based approach. The new guidance requires capitalization once management commits to funding and it is probable the software will be completed and used as intended (probable-to-complete recognition threshold). The standard also clarifies that costs cannot be capitalized when significant development uncertainty exists, such as unresolved technological innovations or unclear performance requirements.
