Accounting Policies [Abstract]

Principles of Consolidation

The condensed consolidated financial statements include the accounts of Kingstone and its wholly-owned subsidiaries: (1) KICO and its wholly-owned subsidiaries, CMIC Properties, Inc. (“Properties”) and 15 Joys Lane, LLC (“15 Joys Lane”), which together, until March 2025, owned the land and building from which KICO operated (see Note 14 - Sale of Real Estate), (2) KAIC, an insurance carrier licensed by the state of Connecticut on May 1, 2026, which plans to begin writing business in the second half of 2026, and (3) Cosi. All significant inter-company account balances and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates and assumptions, including estimates related to reserves for losses and loss adjustment expense (“LAE”), which are subject to estimation errors due to the inherent uncertainty in projecting ultimate claim amounts that will be reported and settled over a period of many years. In addition, estimates and assumptions associated with loss and LAE recoverable under reinsurance contracts and other receivables or payables under reinsurance contracts related to contingent ceding commission revenue require judgments by management. On an ongoing basis, management reevaluates its assumptions and the methods for calculating these estimates. Actual results may differ significantly from the estimates used in preparing the condensed consolidated financial statements.

Accounting Changes

In December 2023, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") No. 2023-09, Improvements to Income Tax Disclosures (“ASU 2023-09”), which requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as information on income taxes paid. The standard is intended to benefit investors by providing

more detailed income tax disclosures that would be useful in making capital allocation decisions. ASU-2023-09 is effective for public companies with annual periods beginning after December 15, 2024. The Company prospectively adopted ASU-2023-09 effective December 31, 2025, and has added the required disclosures that meet the materiality thresholds for the six months ended June 30, 2026. See Note 9 – Income Taxes. The adoption of the guidance updated disclosures but did not have an impact on the Company's results of operations.

Recent Accounting Pronouncements

In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses ("ASU 2024-03"). ASU 2024-03 requires disaggregated disclosure of income statement expenses. ASU 2024-03 does not change the expense captions currently presented on the income statement; rather it requires disaggregation of certain expense captions into specified categories in disclosures within the footnotes to the financial statements. ASU 2024-03 is effective for annual reporting periods, as amended by ASU 2025-01, beginning after December 15, 2026, and interim reporting periods within fiscal years beginning after December 15, 2027. ASU 2024-03 can be applied on a prospective basis; however, retrospective application is permitted. Early adoption is permitted. The Company is currently evaluating the effect the updated guidance will have on its financial statement disclosures.

In September 2025, the FASB issued ASU 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40) ("ASU 2025-06"). ASU 2025-06 updates the accounting guidance for internal-use software by eliminating references to software development project stages, thereby requiring companies to start capitalizing software costs when (i) management has authorized and committed to funding the project and (ii) it is probable the project will be completed and the software will be used as intended. ASU 2025-06 is effective for annual periods beginning after December 15, 2027, with early adoption permitted. Amendments can be applied either (i) prospectively, (ii) through a modified transition approach based on the existing projects status and whether software costs were capitalized before the date of adoption, or (iii) retrospectively. The Company is currently evaluating the impact of ASU 2025-06 on its financial condition and results of operations.

In December 2025, the FASB issued ASU 2025‑11, Interim Reporting (Topic 270): Narrow‑Scope Improvements (“ASU 2025‑11”). ASU 2025‑11 clarifies the scope, form, content, and disclosure requirements applicable to interim financial reporting under U.S. GAAP. ASU 2025-11 improves the navigability of Topic 270 and provides clearer guidance on when the interim reporting requirements apply. Specifically, the amendments (i) clarify that Topic 270 applies to entities that provide interim financial statements and accompanying notes in accordance with GAAP, (ii) add a comprehensive list of required interim disclosures drawn from other FASB topics, and (iii) introduce a disclosure principle requiring entities to disclose events occurring after the end of the most recent annual reporting period that have a material impact on the entity. ASU 2025-11 is not intended to change the fundamental nature of interim reporting, or expand or reduce existing disclosure requirements. ASU 2025‑11 is effective for interim reporting periods within annual periods beginning after December 15, 2027. Early adoption is permitted. The guidance may be applied prospectively or retrospectively. Because ASU 2025‑11 primarily provides clarifying guidance and requires disclosures in certain circumstances, it will not have a material impact on the Company's financial condition or results of operations.

The Company has determined that all other recently issued accounting pronouncements will not have a material impact on its consolidated financial position, results of operations and cash flows, or do not apply to its operations.
