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 June 30, 2026 and for the three and six-month periods ended June 30, 2026 and 2025 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, 2025. 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

Credit losses Effective January 1, 2026, the Company adopted new Financial Accounting Standards Board (“FASB”) guidance that provides a practical expedient for estimating credit losses on current accounts receivable and contract assets arising from revenue transactions accounted for under the guidance for revenue from contracts with customers. The guidance permits entities to assume current conditions remain unchanged over the asset’s remaining life when estimating expected credit losses, simplifying the estimation process. The adoption did not have a material impact on the Company’s financial statements or disclosures.

Pending accounting standards

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,

lease expense, credit losses 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.

Internal-use software In September 2025, the FASB issued guidance which modernizes 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. In addition, website development costs are now included under the same guidance.

The new guidance is effective for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods. Early adoption is permitted as of the beginning of an annual reporting period. The standard may be adopted prospectively, retrospectively, or using a modified transition approach. The Company is currently evaluating the impact of this standard on its financial statements and disclosures.

Codification Improvements In December 2025, the FASB issued guidance introducing targeted amendments and clarifications across multiple areas. Key changes include updates to diluted earnings per share calculations when losses occur from continuing operations and there are potentially dilutive instruments, clarified guidance for treasury stock retirement methods, refinements to accounting for beneficial interests and related interest income and expanded eligibility for the proportional amortization method to all income tax credit investments. The guidance also clarifies the treatment of receivable transfers and excludes certain lease receivables from enhanced credit loss disclosures.

The new guidance is effective for annual reporting periods beginning after December 15, 2026, including interim periods within those annual periods. Early adoption is permitted, and transition methods vary by topic. The Company is currently evaluating the impact of this standard on its financial statements and disclosures.
