Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Management does not expect that its internal control over financial reporting will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Internal control over financial reporting is a process that involves human diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human failures. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. The design of any system of internal control over financial reporting also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Management evaluated the effectiveness of our internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Management reviewed the results of its assessment with the Audit Committee of our Board of Directors. Based on our evaluation, we have concluded that we maintained effective internal control over financial reporting as of December 31, 2025. KPMG LLP, our independent registered public accounting firm, has issued an opinion on the effectiveness of the Company's internal control over financial reporting, as stated in their report which is included herein. Report of Independent Registered Public Accounting Firm To the Stockholders and Board of Directors Kinsale Capital Group, Inc.: Opinion on Internal Control Over Financial Reporting We have audited Kinsale Capital Group, Inc. and subsidiaries' (the Company) internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2025 and 2024, the related consolidated statements of income and comprehensive income, changes in stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2025, and the related notes and financial statement schedules I, II, and V (collectively, the consolidated financial statements), and our report dated February 20, 2026 expressed an unqualified opinion on those consolidated financial statements. Basis for Opinion The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the 68 Table of Contents U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. Definition and Limitations of Internal Control Over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/ KPMG LLP Richmond, Virginia February 20, 2026 69 Table of Contents Report of Independent Registered Public Accounting Firm To the Stockholders and Board of Directors Kinsale Capital Group, Inc.: Opinion on the Consolidated Financial Statements We have audited the accompanying consolidated balance sheets of Kinsale Capital Group, Inc. and subsidiaries (the Company) as of December 31, 2025 and 2024, the related consolidated statements of income and comprehensive income, changes in stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2025, and the related notes and financial statement schedules I, II, and V (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2025, in conformity with U.S. generally accepted accounting principles. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 20, 2026 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting. Basis for Opinion These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion. Critical Audit Matter The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates. Reserves for unpaid losses and loss adjustment expenses As described in Notes 1 and 7 to the consolidated financial statements, the Company records reserves for unpaid losses and loss adjustment expenses (reserves), which represent the Company’s best estimate of ultimate unpaid cost of all reported and unreported losses and loss adjustment expenses incurred prior to the financial statement date. This estimate is based on several actuarial methods. These methods use a variety of inputs based on historical Company and industry data, including initial expected loss ratios, loss development patterns, paid losses, reported losses, claim counts and price indices. All estimates are regularly reviewed and, as experience develops and new information becomes known, the reserves are adjusted as necessary. As of December 31, 2025, the Company recorded $2,891 million of reserves for unpaid losses and loss adjustment expenses. We identified the evaluation of the estimation of reserves as a critical audit matter. The evaluation of the Company’s best estimate of reserves required complex auditor judgment due to the inherent uncertainty in the ultimate amount and timing of claim payments and required specialized actuarial skills and knowledge. In addition, the evaluation of 70 Table of Contents assumptions used in the estimate of reserves required subjective auditor judgment due to the Company’s limited historical claims data and, therefore, also involved consideration of industry data. The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls related to the Company’s reserving process. These included internal controls over the actuarial methods and certain assumptions used to derive the Company’s best estimate of reserves and the comparison of the Company’s best estimate to the annual independent actuarial reserve estimate performed by an external consulting actuary. We also involved actuarial professionals with specialized skills and knowledge, who assisted in: • assessing the Company’s reserving methodology by comparing to methods consistent with generally accepted actuarial standards and practices • performing independent estimates of reserves for certain lines of business, using a combination of the Company’s underlying historical claims and industry data with respect to future claim reporting amounts and payment patterns, as well as prior year independent selected loss rates • developing an independent range of reserves using both the Company’s underlying historical claims and industry data with respect to future claim reporting amounts and payment patterns, as well as prior year independent selected loss rates • assessing the position of the Company’s recorded reserves within this independent range in the current year and comparing to its relative position in the prior year. /s/ KPMG LLP We have served as the Company’s auditor since 2009.

Kinsale Capital Group, Inc. writes excess and surplus lines insurance on a non-admitted basis principally through its insurance subsidiary, Kinsale Insurance Company ("Kinsale Insurance"), which is authorized to write business in 50 states, the District of Columbia, the Commonwealth of Puerto Rico and the U.S. Virgin Islands. Kinsale Capital Group, Inc. also markets certain products through its subsidiary, Aspera Insurance Services, Inc. ("Aspera"), an insurance broker. 1. Summary of significant accounting policies Principles of consolidation The accompanying consolidated financial statements include the accounts of Kinsale Capital Group, Inc. and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. Certain prior year amounts have been reclassified to conform to the current year's presentation. Use of estimates The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles ("U.S. GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities, if any, at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Management periodically reviews its estimates and assumptions. These reviews include evaluating the adequacy of reserves for unpaid losses and loss adjustment expenses, allowance for credit losses and uncollectible reinsurance, fair value of investments, as well as evaluating the investment portfolio for credit impairments. Cash and cash equivalents The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents. Short-term investments Short-term investments are carried at amortized cost, which approximates fair value. Short-term investments have maturities greater than three months but less than one year at the date of purchase. Fixed-maturity and equity securities Fixed-maturity securities are classified as available-for-sale and reported at fair value. Unrealized gains and losses on these securities are excluded from earnings but are recorded as a separate component of other comprehensive income and stockholders' equity, net of deferred income taxes. Equity securities are reported at fair value. Changes in unrealized gains and losses in fair value of these investments are recognized in net income. The Company regularly reviews all its available-for-sale investments with unrealized losses to assess whether the decline in the fair value is deemed to be a credit loss. See Note 2 for further discussion regarding the determination of credit losses. Interest on fixed-maturity securities is credited to earnings as it accrues. Premiums and discounts are amortized or accreted using the effective interest method over the lives of the related fixed maturities, or to the earliest call date for 76 Table of Contents securities purchased at a premium. This method includes an adjustment for estimated principal prepayments, if any, on asset- and mortgage-backed securities. To the extent that the estimated lives of such securities change as a result of changes in estimated prepayment rates, the adjustments are included in net investment income using the retrospective method. Dividends on equity securities are included in earnings on the ex-dividend date. Realized gains and losses on disposition of investments are based on specific identification of the investments sold on the trade date. Real estate investments Real estate investments include real estate and the related assets purchased for investment purposes. Real estate and the related depreciable assets are carried at cost, net of accumulated depreciation. Depreciation is calculated on a straight-line basis over the estimated useful life of the assets and is included in net investment income. Rental income is recognized on a straight-line basis over the term of the respective lease and is included in net investment income. Land is not depreciated. Real estate is evaluated for impairment when events or circumstances indicate the carrying value of the real estate may not be recoverable. Reinsurance Reinsurance premiums, commissions, and ceded unearned premiums on reinsured business are accounted for on a basis consistent with that used in accounting for the original policies issued and the terms of the reinsurance contracts. The Company receives ceding commissions in accordance with certain reinsurance treaties. The ceding commissions are capitalized and amortized as a reduction of underwriting, acquisition and insurance expenses. Reinsurance recoverables represent paid losses and loss adjustment expenses and reserves for unpaid losses and loss adjustment expenses ceded to reinsurers that are subject to reimbursement under reinsurance treaties. The method for determining reinsurance recoverables for unpaid losses and loss adjustment expenses involves reviewing actuarial estimates of gross unpaid losses and loss adjustment expenses to determine the Company's ability to cede unpaid losses and loss adjustment expenses under the Company's existing reinsurance contracts. This method is continually reviewed and updated and any resulting adjustments are reflected in earnings in the period identified. See Note 8 for a further discussion of the Company's reinsurance program. Premiums receivable, net Premiums receivable balances are carried at face value, net of any allowance for credit losses. The allowance for credit losses represents an estimate of amounts considered uncollectible based on the Company’s assessment of the collectability of receivables that are past due. The estimate considers historical loss data, current and future economic conditions and specific identification of collectability concerns where applicable. The following table presents the rollforward of the allowance for credit losses for premiums receivable for the years ended December 31, 2025 and 2024: Year Ended December 31, 2025 2024 (in thousands) Beginning balance $ 26,926 $ 13,383 Current period change for estimated uncollectible premiums 10,503 17,397 Write-offs of uncollectible premiums receivable ( 10,101 ) ( 3,854 ) Ending balance $ 27,328 $ 26,926 77 Table of Contents Deferred policy acquisition costs, net of ceding commissions The Company defers commissions, net of ceding commissions, and certain other costs that are directly related to the successful acquisition of insurance contracts. All eligible costs are capitalized and charged to expense in proportion to premium earned over the estimated policy life. To the extent that unearned premiums on existing policies are not adequate to cover the related costs and expenses, referred to as a premium deficiency, deferred policy acquisition costs are charged to earnings. The Company considers anticipated investment income in determining whether a premium deficiency exists. Property and equipment, net Property and equipment are stated at cost less accumulated depreciation. Depreciation of property and equipment is calculated using the straight-line method over the estimated useful lives of the assets. The estimated useful lives range from 39 years for the building and parking deck, 15 to 20 years for land improvements, 7 to 10 years for furniture and equipment, and 3 to 7 years for electronic data processing hardware and software. Property and equipment are included in other assets in the accompanying consolidated balance sheets and consists of the following: December 31, 2025 2024 (in thousands) Building $ 66,763 $ 37,190 Parking deck — 5,072 Land — 3,068 Equipment 5,375 4,401 Software 27,136 20,203 Furniture and fixtures 6,157 3,200 Leasehold improvements — 153 Land improvements 129 474 Construction in progress - building 376 26,530 105,936 100,291 Accumulated depreciation ( 16,505 ) ( 17,367 ) Total property and equipment, net $ 89,431 $ 82,924 In 2024, construction in progress included capitalized expenses related to the development of the Company's new corporate headquarters building. Construction of the new headquarters building was substantially completed in the fourth quarter of 2025 and was placed into service. Upon moving operations to the new headquarters, the Company reclassified its former headquarters and related assets from property and equipment to real estate investments due to a change in the intended use of the former property. Indefinite-lived intangible assets Indefinite-lived intangible assets are recorded at fair value at the date of acquisition. The Company's indefinite-lived intangible assets are comprised solely of regulatory approvals granted by the various state insurance departments to write insurance business in the respective states on a non-admitted basis. In accordance with U.S. GAAP, amortization of indefinite-lived intangible assets is not permitted. Indefinite-lived intangible assets are tested for impairment during the fourth quarter on an annual basis, or earlier if there is reason to suspect that their values may have been diminished or impaired. There were no impairments recognized in December 31, 2025, 2024, or 2023. In addition, as of December 31, 2025, no triggering events occurred that suggested an updated review was necessary. Reserves for unpaid losses and loss adjustment expenses Reserves for unpaid losses and loss adjustment expenses represent management's best estimate of ultimate unpaid cost of all reported and unreported losses and loss adjustment expenses incurred prior to the financial statement date. The estimates are based on several actuarial methods that use a variety of inputs including initial expected loss ratios, loss 78 Table of Contents development patterns, paid losses, reported losses, claim counts and price indices. All estimates are regularly reviewed and, as experience develops and new information becomes known, the reserves for unpaid losses and loss adjustment expenses are adjusted as necessary. Such adjustments are reflected in the results of operations in the period in which they are determined. Although management believes that the reserves for losses and loss adjustment expenses are reasonable, due to the inherent uncertainty in estimating reserves for unpaid losses and loss adjustment expenses, it is possible that the Company’s actual incurred losses and loss adjustment expenses will not develop in a manner consistent with the assumptions inherent in the determination of these reserves. If actual liabilities exceed recorded amounts, there will be an increase to the Company’s reserves resulting in a reduction in net income and stockholders’ equity in the period in which the deficiency is identified. Furthermore, management may determine that recorded reserves are more than adequate to cover expected losses which will result in a reduction to the reserves. The Company believes that the reserves for unpaid losses and loss adjustment expenses at December 31, 2025 and 2024 are adequate and represent a reasonable estimate of the Company's future obligations. See Note 7 for a further discussion of reserves for unpaid losses and loss adjustment expenses. Revenue recognition Premiums are recognized as revenue ratably over the term of the insurance contracts, net of ceded reinsurance. Unearned premiums are calculated on a daily pro rata basis. Fee income is recognized as revenue when the related premium is written. Income taxes Deferred income tax assets and liabilities are determined based on the differences between the recorded amounts and the tax bases of assets and liabilities, using enacted tax rates expected to be in effect during the year in which the basis differences reverse. The effect on deferred taxes of a change in tax rates is recognized in income in the period in which such change was enacted. Valuation allowances on deferred tax assets are estimated based on the Company's assessment of the realizability of such amounts. Valuation allowances are recorded when it is more likely than not that some portion, or all, of the deferred tax assets will not be realizable. The Company provides for uncertain tax positions, and the related interest and penalties, based upon management’s assessment of whether a tax benefit is more likely than not to be sustained upon examination by tax authorities. To the extent that the anticipated tax outcome of these uncertain tax positions changes, such changes in estimate will impact the income tax provision in the period in which such determination is made. The Company recognizes accrued interest and penalties related to uncertain tax positions as a component of income tax expense. The Company uses the portfolio approach to release stranded tax effects in accumulated other comprehensive income ("AOCI") related to its available-for-sale fixed-maturity securities. Under this approach, stranded tax effects remaining in AOCI are released only when the entire portfolio of the available-for-sale fixed-maturity securities are liquidated, sold or extinguished. Contingencies Liabilities for loss contingencies, arising from noninsurance policy claims, assessments, litigation, fines, and penalties and other sources, are recorded when it is probable that a liability has been incurred and the amount of the assessment and/or remediation can be reasonably estimated. Legal costs incurred in connection with loss contingencies are expensed as incurred. Fair value of financial instruments Fair value is estimated for each class of financial instrument based on the framework established in the fair value accounting guidance. This guidance requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Fair value hierarchy disclosures are based on the quality of inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). See Note 3 for further details regarding fair value disclosures. 79 Table of Contents Stock-based compensation Stock-based compensation is expensed based upon the estimated fair value of employee stock awards. Compensation cost for awards of equity instruments to employees is measured based on the grant-date fair value of those awards and compensation expense is recognized over the service period that the awards vest. Forfeitures of stock-based compensation awards are recognized as they occur. See Note 9 for further discussion and related disclosures regarding stock-based compensation. Recently adopted accounting pronouncements Accounting Standards Update ("ASU") 2023-09 – Income Taxes (Topic 740): Improvements to Income Tax Disclosures In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures". The amended guidance enhances income tax disclosures primarily related to the effective tax rate reconciliation and income taxes paid information. This guidance requires disclosure of specific categories in the effective tax rate reconciliation and additional information on reconciling items meeting a quantitative threshold. In addition, the amended guidance requires disaggregating income taxes paid (net of refunds received) by federal, state, and foreign taxes. It also requires disaggregating individual jurisdictions in which income taxes paid (net of refunds received) are equal to or greater than 5 percent of total income taxes paid (net of refunds received). The amended guidance became effective for the year ended December 31, 2025. Refer to Note 6 for the Company's income tax disclosures.

The Company considers a number of factors in completing its review of credit losses, including the extent to which a security's fair value has been below cost and the financial condition of an issuer. In addition to specific issuer information, the Company also evaluates the current market and interest rate environment. Generally, a change in a security’s value caused by a change in the market or interest rate environment does not constitute a credit loss. For fixed-maturity securities, the Company also considers whether it intends to sell the security or if it is more likely than not that it will be required to sell the security before recovery and the ability to recover all amounts outstanding when contractually due. When assessing whether it intends to sell a fixed-maturity security or if it is likely to be required to sell a fixed-maturity security before recovery of its amortized cost, the Company evaluates facts and circumstances including, but not limited to, decisions to reposition the investment portfolio, potential sales of investments to meet cash flow needs and potential sales of investments to capitalize on favorable pricing. 81 Table of Contents For fixed-maturity securities where a decline in fair value is below the amortized cost basis and the Company intends to sell the security, or it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost, an impairment is recognized in net income based on the fair value of the security at the time of assessment. For fixed-maturity securities that the Company does not intend to sell or for which it is more likely than not that the Company would not be required to sell before recovery of its amortized cost, the Company compares the estimated present value of the cash flows expected to be collected to the amortized cost of the security. Inputs into the present value cash flow analysis include default rates and recoverability rates based on credit rating. The extent to which the estimated present value of the cash flows expected to be collected is less than the amortized cost of the security represents the credit-related portion of the impairment, which is recognized in net income through an allowance for credit losses. Any remaining decline in fair value represents the noncredit portion of the impairment, which is recognized in other comprehensive income. The Company reports investment income due and accrued separately from fixed-maturity securities, available for sale, and has elected not to measure an allowance for credit losses for investment income due and accrued. Investment income due and accrued is written off through earnings at the time the issuer of the bond defaults or is expected to default on payments. As of December 31, 2025, the Company's credit loss review resulted in an allowance for credit losses on three securities. The following table presents changes in the allowance for expected credit losses on available-for-sale securities: Years Ended December 31, 2025 2024 (in thousands) Beginning balance $ 27 $ 553 Increase to allowance from securities for which credit losses were not previously recorded — 3 Reduction from securities sold during the period ( 14 ) ( 479 ) Net increase (decrease) from securities that had an allowance at the beginning of the period 16 ( 50 ) Ending balance $ 29 $ 27 82 Table of Contents The following tables summarize gross unrealized losses and estimated fair value for available-for-sale investments by length of time that the securities have continuously been in an unrealized loss position: December 31, 2025 Less than 12 Months 12 Months or Longer Total Estimated Fair Value Gross Unrealized Losses Estimated Fair Value Gross Unrealized Losses Estimated Fair Value Gross Unrealized Losses (in thousands) Fixed maturities: U.S. Treasury securities and obligations of U.S. government agencies $ 296 $ ( 1 ) $ — $ — $ 296 $ ( 1 ) Obligations of states, municipalities and political subdivisions 1,043 ( 2 ) 118,027 ( 18,408 ) 119,070 ( 18,410 ) Corporate and other securities 101,385 ( 597 ) 239,152 ( 25,635 ) 340,537 ( 26,232 ) Asset-backed securities 92,682 ( 384 ) 7,759 ( 254 ) 100,441 ( 638 ) Residential mortgage-backed securities 387,397 ( 779 ) 228,531 ( 37,971 ) 615,928 ( 38,750 ) Commercial mortgage-backed securities 103,868 ( 296 ) 44,139 ( 2,169 ) 148,007 ( 2,465 ) Total fixed-maturity investments $ 686,671 $ ( 2,059 ) $ 637,608 $ ( 84,437 ) $ 1,324,279 $ ( 86,496 ) At December 31, 2025, in addition to the securities included in the allowance for credit losses, the Company held 592 fixed-maturity securities with a total estimated fair value of $ 1.3 billion and gross unrealized losses of $ 86.5 million. Of those securities, 483 were in a continuous unrealized loss position for greater than one year. As discussed above, the Company regularly reviews all fixed-maturity securities within its investment portfolio to determine whether a credit loss has occurred. Based on the Company's review as of December 31, 2025, except for securities previously discussed, the securities in unrealized loss positions were caused by interest rate changes or other market factors and were not credit-specific issues, nor did the Company intend to sell these securities. At December 31, 2025, 81.9 % of the Company’s fixed-maturity securities were rated "A-" or better and all of Company's fixed-maturity securities made expected coupon payments under the contractual terms of the securities.

Real estate investments Real estate investments represents directly owned property held for investment purposes. In December 2025, the Company reclassified its former headquarters and related assets to real estate investments. Accumulated depreciation on real estate investments was $ 5.7 million at December 31, 2025. There was no accumulated depreciation at December 31, 2024 as real estate investments consisted of land. Net investment income The following table presents the components of net investment income: Year Ended December 31, 2025 2024 2023 (in thousands) Interest: Taxable bonds $ 180,911 $ 143,242 $ 92,227 Municipal bonds (tax exempt) 1,390 1,592 2,217 Cash equivalents and short-term investments 6,185 3,012 3,004 Dividends on equity securities 8,602 6,442 5,097 Real estate investment income — 153 3,716 Gross investment income 197,088 154,441 106,261 Investment expenses ( 4,896 ) ( 4,154 ) ( 3,926 ) Net investment income $ 192,192 $ 150,287 $ 102,335 There was no depreciation expense related to real estate investments for the years ended December 31, 2025 and 2024 as the depreciable assets were in use by the Company prior to December 31, 2025. Investment expenses included depreciation expense related to real estate investments of $ 0.5 million for the year ended December 31, 2023. 84 Table of Contents Realized investment gains and losses The following table presents realized investment gains and losses: Year Ended December 31, 2025 2024 2023 (in thousands) Fixed-maturity securities: Realized gains $ 8,506 $ 1,151 $ 1,852 Realized losses ( 4,673 ) ( 1,131 ) ( 2,374 ) Net realized gains (losses) from fixed-maturity securities 3,833 20 ( 522 ) Equity securities: Realized gains 2,465 7,271 7,678 Realized losses ( 1,910 ) ( 455 ) ( 5,329 ) Net realized gains from equity securities 555 6,816 2,349 Realized gains (losses) from the sales of short-term investments 2 — ( 37 ) Realized (losses) gains on sale of real estate investments — ( 5 ) 4,250 Net realized investment gains $ 4,390 $ 6,831 $ 6,040 The net realized gains or losses on sales of equity securities represent the total gains or losses from the purchase dates of the equity securities.

Change in net unrealized gains (losses) on fixed-maturity securities The change in net unrealized gains (losses) for fixed-maturity securities was $ 84.2 million, $( 3.3 ) million, and $ 51.0 million for the years ended December 31, 2025, 2024, and 2023, respectively. Insurance – statutory deposits The Company had invested assets with a carrying value of $ 3.9 million and $ 3.7 million on deposit with state regulatory authorities at December 31, 2025 and 2024, respectively. Payable for investments purchased The Company did not have a payable for investments purchased at December 31, 2025 or 2024. 3. Fair value measurements Fair value is estimated for each class of financial instrument based on the framework established in the fair value accounting guidance. Fair value is defined as the price in the principal market that would be received for an asset or paid to transfer a liability to facilitate an orderly transaction between market participants on the measurement date. Market participants are assumed to be independent, knowledgeable, able and willing to transact an exchange and not acting under duress. Fair value hierarchy disclosures are based on the quality of inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Adjustments to transaction prices or quoted market prices may be required in illiquid or disorderly markets in order to estimate fair value. The three levels of the fair value hierarchy are defined as follows: Level 1 - Inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities traded in active markets. 85 Table of Contents Level 2 - Inputs to the valuation methodology include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability and market-corroborated inputs. Level 3 - Inputs to the valuation methodology are unobservable for the asset or liability and are significant to the fair value measurement. Fair values of the Company's investment portfolio are estimated using unadjusted prices obtained by its investment accounting vendor from nationally recognized third-party pricing services, where available. Values for U.S. Treasuries, exchange traded funds and common stocks are generally based on Level 1 inputs which use quoted prices in active markets for identical assets. For other fixed-maturity securities and non-redeemable preferred stock, the pricing vendors use a pricing methodology involving the market approach, including pricing models which use prices and relevant market information regarding a particular security or securities with similar characteristics to establish a valuation. The estimates of fair value of these investments are included in the amounts disclosed as Level 2. For those investments where significant inputs are unobservable, the Company's investment accounting vendor obtains valuations from pricing vendors or brokers using the market approach and income approach valuation techniques and are disclosed as Level 3. Management performs several procedures to ascertain the reasonableness of investment values included in the consolidated financial statements at December 31, 2025 and 2024, including 1) obtaining and reviewing internal control reports from the Company's investment accounting vendor that assess fair values from third party pricing services, 2) discussing with the Company's investment accounting vendor its process for reviewing and validating pricing obtained from third party pricing services and 3) reviewing the security pricing received from the Company's investment accounting vendor and monitoring changes in unrealized gains and losses at the individual security level. The Company has evaluated the various types of securities in its investment portfolio to determine an appropriate fair value hierarchy level based upon trading activity and the observability of market inputs. The following tables present the balances of assets measured at fair value on a recurring basis as of December 31, 2025 and 2024, by level within the fair value hierarchy: December 31, 2025 Level 1 Level 2 Level 3 Total (in thousands) Assets Fixed maturities: U.S. Treasury securities and obligations of U.S. government agencies $ 874 $ — $ — $ 874 Obligations of states, municipalities and political subdivisions — 127,860 — 127,860 Corporate and other securities — 1,713,888 — 1,713,888 Asset-backed securities — 588,519 — 588,519 Residential mortgage-backed securities — 1,459,270 — 1,459,270 Commercial mortgage-backed securities — 451,039 — 451,039 Total fixed maturities 874 4,340,576 — 4,341,450 Equity securities: Exchange traded funds 185,523 — — 185,523 Non-redeemable preferred stock — 24,100 — 24,100 Common stocks 416,776 — — 416,776 Total equity securities 602,299 24,100 — 626,399 Short-term investments 3,864 — — 3,864 Total $ 607,037 $ 4,364,676 $ — $ 4,971,713 86 Table of Contents December 31, 2024 Level 1 Level 2 Level 3 Total (in thousands) Assets Fixed maturities: U.S. Treasury securities and obligations of U.S. government agencies $ 15,048 $ — $ — $ 15,048 Obligations of states, municipalities and political subdivisions — 146,304 — 146,304 Corporate and other securities — 1,989,490 — 1,989,490 Asset-backed securities — 732,742 — 732,742 Residential mortgage-backed securities — 448,874 — 448,874 Commercial mortgage-backed securities — 205,105 — 205,105 Total fixed maturities 15,048 3,522,515 — 3,537,563 Equity securities: Exchange traded funds 129,731 — — 129,731 Non-redeemable preferred stock — 26,433 — 26,433 Common stocks 242,195 — — 242,195 Total equity securities 371,926 26,433 — 398,359 Short-term investments 3,714 — — 3,714 Total $ 390,688 $ 3,548,948 $ — $ 3,939,636 There were no assets or liabilities measured at fair value on a nonrecurring basis as of December 31, 2025 or 2024. The carrying amount of the Company's fixed-rate senior notes was $ 175.0 million, less debt issuance cost, and the corresponding estimated fair value was $ 173.8 million and $ 168.6 million at December 31, 2025 and 2024, respectively. The fair value measurement was determined using a discounted cash flow analysis that factors in current market yields for comparable borrowing arrangements under the Company's credit profile. Since this methodology is based upon market yields for comparable arrangements, the measurement is categorized as Level 2. The estimated fair value of outstanding borrowings under the Company's revolving Credit Facility approximated its carrying value at December 31, 2025 and 2024. See Note 11 for further information regarding the Company's debt arrangements. The Company holds cash equivalents that are managed as part of its investment portfolio and, due to the short-term maturities of these assets, the carrying value of these investments approximates fair value. The Company held cash equivalents of $ 45.3 million and $ 16.1 million at December 31, 2025 and 2024, respectively. 87 Table of Contents 4.

Underwriting, acquisition and insurance expenses Underwriting, acquisition and insurance expenses consist of the following: Year Ended December 31, 2025 2024 2023 (in thousands) Underwriting, acquisition and insurance expenses incurred: Direct commissions $ 286,268 $ 254,523 $ 198,715 Ceding commissions ( 119,466 ) ( 120,339 ) ( 84,998 ) Other underwriting expenses 169,894 151,624 115,253 Total $ 336,696 $ 285,808 $ 228,970 Other underwriting expenses within underwriting, acquisition and insurance expenses included salaries, employee benefits and bonus expense of $ 128.9 million, $ 109.3 million and $ 85.7 million, for the years ended December 31, 2025, 2024 and 2023, respectively. 6. Income taxes The Company’s subsidiaries file a consolidated U.S. federal income tax return. Under a tax sharing agreement, Kinsale collects from or refunds to its subsidiaries the amount of taxes determined as if Kinsale and the subsidiaries filed separate returns. The Company is no longer subject to income tax examination by tax authorities for the years ended before January 1, 2022. The Company’s insurance subsidiary, Kinsale Insurance, is not subject to state income taxes in the states in which it operates and is instead subject to premium taxes. The Company’s non-insurance subsidiaries are subject to state income taxes; however, they have generated state net operating loss carryforwards, for which a full valuation allowance is established. On July 4, 2025, the One Big Beautiful Bill Act ("OBBBA") was enacted into law. The OBBBA extends or makes permanent various tax provisions that were originally enacted in the 2017 Tax Cuts and Jobs Act and were set to expire at the end of 2025. The tax provisions in the OBBBA did not have a material impact on the Company's consolidated financial statements. 88 Table of Contents Components of Income Tax Expense The Company operates exclusively within the United States and, as such, has no foreign operations or foreign income. For the years ending December 31, 2025, 2024 and 2023, income before income tax expense includes the following components: Year Ended December 31, 2025 2024 2023 (in thousands) Income from continuing operations before income tax expense U.S. $ 634,302 $ 514,716 $ 384,017 Total $ 634,302 $ 514,716 $ 384,017 For the years ending December 31, 2025, 2024 and 2023, income tax expense (benefit) from continuing operations consisted of: Year Ended December 31, 2025 2024 2023 (in thousands) Income tax expense (benefit) from continuing operations Current tax expense U.S. federal $ 130,345 $ 103,701 $ 85,353 U.S. state and local — — — Total current tax expense 130,345 103,701 85,353 Deferred tax expense (benefit) U.S. federal 343 ( 3,828 ) ( 9,429 ) U.S. state and local — — — Total deferred tax expense (benefit) 343 ( 3,828 ) ( 9,429 ) Total income tax expense $ 130,688 $ 99,873 $ 75,924 Income taxes paid The Company paid total income taxes (net of refunds received) of $ 129.6 million, $ 104.1 million, and $ 84.6 million for the years ending December 31, 2025, 2024 and 2023, respectively, all of which related to federal income taxes. Current income taxes payable were $ 3.6 million and $ 2.8 million at December 31, 2025 and 2024, respectively, and are included in other liabilities in the accompanying consolidated balance sheets. 89 Table of Contents Rate reconciliation The prevailing federal income tax rate was 21 % for the years ending December 31, 2025, 2024 and 2023. The reconciliation of the statutory U.S. federal income tax rate to the Company’s effective tax rate for the years ending December 31, 2025, 2024 and 2023 is as follows: Year Ended December 31, 2025 2024 2023 (in thousands) Amount Percent Amount Percent Amount Percent U.S. federal statutory income tax rate $ 133,203 21.0 % $ 108,090 21.0 % $ 80,644 21.0 % U.S. federal Tax credits ( 500 ) ( 0.1 ) % — — % — — % Nontaxable and nondeductible items 2,885 0.5 % 1,902 0.4 % 212 0.1 % Excess tax benefits on share-based payments ( 4,900 ) ( 0.8 ) % ( 10,119 ) ( 2.0 ) % ( 4,932 ) ( 1.3 ) % Total $ 130,688 20.6 % $ 99,873 19.4 % $ 75,924 19.8 % The Company's effective tax rate for the years ended December 31, 2025, 2024 and 2023, were 20.6 %, 19.4 % and 19.8 % compared to the statutory federal rate of 21 %. The difference primarily resulted from tax benefits from stock-based compensation, including stock options exercised, and from income generated by certain tax-exempt investments. The significant components of the net deferred tax asset are summarized as follows: December 31, 2025 2024 (in thousands) Deferred tax assets: Unrealized losses on fixed-maturity securities $ 8,662 $ 26,343 Unpaid losses and loss adjustment expenses 49,288 36,491 Unearned premiums 34,267 32,580 State operating loss carryforwards 10,216 8,859 Stock compensation 3,158 3,276 Allowance for credit losses 5,742 5,210 Other 2,145 1,939 Deferred tax assets before allowance 113,478 114,698 Less: valuation allowance ( 10,119 ) ( 9,066 ) Total deferred tax assets 103,359 105,632 Deferred tax liabilities: Unrealized gains on equity securities 30,129 17,774 Deferred policy acquisition costs, net of ceding commissions 24,935 22,945 Property and equipment 4,894 3,263 Other 1,210 1,435 Total deferred tax liabilities 61,168 45,417 Net deferred tax asset $ 42,191 $ 60,215 At December 31, 2025 and 2024, the Company had state net operating losses ("NOLs") of $ 215.5 million and $ 186.9 million, respectively. The state NOLs are available to offset future taxable income or reduce taxes payable and begin expiring in 2029. 90 Table of Contents Management evaluates the need for a valuation allowance related to its deferred tax assets. At December 31, 2025 and 2024, the Company recorded a tax valuation allowance equal to the state NOLs and the deferred tax assets, net of existing deferred tax liabilities that were expected to reverse in future periods, related to certain state jurisdictions. No other valuation allowances were established against the Company’s deferred tax assets at December 31, 2025 and 2024, as the Company believes that it is more likely than not that the remaining deferred tax assets will be realized given the carry back availability, reversal of existing temporary differences and future taxable income. With respect to deferred tax assets associated with unrealized losses on fixed-maturity securities, management has the ability and intent to execute a tax planning strategy to hold those securities to recovery or maturity to the extent not matched with realized capital gains or available carry back to ensure recognition of the deferred tax asset. After consideration of all available evidence, we concluded that it is more likely than not that these deferred tax assets will be realized. The Company did not have any material uncertain tax positions in 2025 or 2024. Management is not aware of any events that would give rise to any material uncertain tax positions. 91 Table of Contents 7. Reserves for unpaid losses and loss adjustment expenses The reserves for unpaid losses and loss adjustment expenses represent the Company's estimated ultimate cost of all unreported and reported but unpaid insured claims and the cost to adjust these claims. Reserves are estimated using individual case-basis valuations of reported claims and statistical analyses. Case reserves are established for individual claims that have been reported to the Company, typically by the Company's insureds or their brokers. Based on the information provided, case reserves are established by estimating the ultimate losses from the claim, including defense costs associated with the ultimate settlement of the claim. Incurred-but-not-reported ("IBNR") reserves are determined using actuarial methods to estimate losses that have occurred but have not yet been reported to the Company. Various actuarial methods are used to arrive at the Company's loss reserve estimates for each line of business. These methods utilize numerous inputs including initial expected loss ratios, loss development patterns, paid losses, reported losses, claim counts and price indices. The Company also uses industry and peer-group data, in addition to its own data, to assist in analyzing loss development patterns by line of business. As part of the reserving process, the Company reviews historical data and considers the effect of various factors on claims development patterns including polices written on a "claims made" versus "occurrence" basis. Policies written on a claims made basis provide coverage to the insured only for losses incurred during the coverage period, and only if the claim was reported during a specified reporting period. Policies written on an occurrence basis provide coverage to the insured for liabilities arising from events occurring during the term of the policy, regardless of when a claim is actually made. Accordingly, claims related to policies written on an occurrence basis may arise many years after a policy has lapsed. Property losses, while written on an occurrence basis, are generally reported within a short time from the date of loss, and in most instances, property claims are settled and paid within a relatively short period of time. The following table presents a reconciliation of consolidated beginning and ending reserves for unpaid losses and loss adjustment expenses: December 31, 2025 2024 2023 (in thousands) Gross reserves for unpaid losses and loss adjustment expenses, beginning of year $ 2,285,668 $ 1,692,875 $ 1,238,402 Less: reinsurance recoverable on unpaid losses 323,060 241,357 177,039 Net reserves for unpaid losses and loss adjustment expenses, beginning of year 1,962,608 1,451,518 1,061,363 Incurred losses and loss adjustment expenses: Current year 953,510 810,554 635,993 Prior years ( 62,817 ) ( 37,655 ) ( 35,774 ) Total net losses and loss adjustment expenses incurred 890,693 772,899 600,219 Payments: Current year 64,288 49,747 38,565 Prior years 279,499 212,062 171,499 Total payments 343,787 261,809 210,064 Net reserves for unpaid losses and loss adjustment expenses, end of year 2,509,514 1,962,608 1,451,518 Reinsurance recoverable on unpaid losses, net of allowance 381,356 323,060 241,357 Gross reserves for unpaid losses and loss adjustment expenses, end of year $ 2,890,870 $ 2,285,668 $ 1,692,875 During the year ended December 31, 2025, prior accident years developed favorably by $ 62.8 million, of which $ 70.9 million was attributable to the 2020 through 2024 accident years due to lower emergence of reported losses than expected across most lines of business, particularly in the property lines of business. This favorable development was offset in part by adverse development primarily in the construction liability business in the 2016 through 2019 accident years and adjustments to actuarial assumptions in the 2020 through 2024 accident years to reflect inflation uncertainty around construction defect exposures. 92 Table of Contents Current accident year incurred losses and loss adjustment expenses for the year ended December 31, 2025 included $ 30.4 million of net catastrophe losses primarily related to the Palisades Fire. During the year ended December 31, 2024, prior accident years developed favorably by $ 37.7 million, of which $ 57.6 million was attributable to the 2021 through 2023 accident years due to lower emergence of reported losses than expected across most lines of business. This favorable development was offset in part by adverse development primarily from the 2017 through 2019 accident years due to construction defect claims that are more exposed to inflation, from the 2020 accident year due to a large property claim and more conservative actuarial assumptions in the 2021 through 2023 accident years for lines of business exposed to construction liability. Current accident year incurred losses and loss adjustment expenses for the year ended December 31, 2024 included $ 25.5 million of net catastrophe losses primarily related to Hurricanes Milton, Helene and Francine and tornadoes in the Midwest. During the year ended December 31, 2023, prior accident years developed favorably by $ 35.8 million, of which $ 49.0 million was attributable to the 2021 and 2022 accident years due to lower emergence of reported losses than expected across most lines of business. This favorable development was offset in part by adverse development largely from the 2017 and 2019 accident years due to construction defect claims that are more exposed to inflation. Incurred and Paid Claims Development The following is information about incurred and paid claims development as of December 31, 2025, net of reinsurance, as well as cumulative claim frequency and the total of IBNR liabilities plus expected development on reported claims included within the net incurred claims amounts. The development and claims duration tables below exclude commuted multi-line quota-share reinsurance treaty ("MLQS") contracts, which would distort development patterns related to those transactions. Cumulative number of reported claims is reported on a per claim basis. The information about incurred and paid claims development for the years ended December 31, 2016 to December 31, 2024 is presented as unaudited supplementary information.

Reinsurance The Company purchases reinsurance from other insurance companies ("reinsurers") in order to limit its exposure to large losses and enable it to underwrite policies with sufficient limits to meet policyholder needs. In a reinsurance transaction, an insurance company transfers, or cedes, part or all of its exposure to the reinsurer that receives a portion of the premium. The ceding of insurance does not legally discharge the Company from its primary liability for the full amount of the policy coverage, and therefore the Company will be required to pay the loss and bear collection risk if the reinsurer fails to meet its obligations under the reinsurance agreement. The following table summarizes the effect of reinsurance on premiums written and earned: Year Ended December 31, 2025 2024 2023 (in thousands) Written: Direct $ 1,977,171 $ 1,870,341 $ 1,568,815 Ceded ( 361,154 ) ( 392,993 ) ( 304,185 ) Net written $ 1,616,017 $ 1,477,348 $ 1,264,630 Earned: Direct $ 1,945,225 $ 1,743,243 $ 1,367,141 Ceded ( 369,383 ) ( 392,773 ) ( 294,604 ) Net earned $ 1,575,842 $ 1,350,470 $ 1,072,537 Incurred losses and loss adjustment expenses were net of reinsurance recoverables (ceded incurred losses and loss adjustment expenses) of $ 121.9 million, $ 125.4 million and $ 115.9 million for the years ended December 31, 2025, 2024 and 2023, respectively. Reinsurance balances The following table presents reinsurance recoverables on paid and unpaid losses as of December 31, 2025 and 2024: December 31, 2025 December 31, 2024 (in thousands) Reinsurance recoverables on paid losses $ 12,973 $ 14,831 Reinsurance recoverables on unpaid losses 381,356 323,060 Reinsurance recoverables $ 394,329 $ 337,891 Credit risk exists with reinsurance ceded to the extent that any reinsurer is unable to meet the obligations assumed under the reinsurance agreements. Allowances are established for amounts deemed uncollectible. The Company evaluates the financial condition of its reinsurers and monitors concentration of credit risk arising from its exposure to individual reinsurers. All reinsurance recoverables are from companies with A.M. Best ratings of "A-" (Excellent) or better. To further reduce credit exposure to reinsurance recoverable balances, the Company has received letters of credit from certain reinsurers that are not authorized as reinsurers under U.S. state insurance regulations. The Company recorded an allowance for credit losses of $ 1.1 million and $ 0.9 million related to its reinsurance balances at December 31, 2025 and 2024, respectively; however, the deterioration in the credit quality of existing reinsurers or disputes over reinsurance agreements could result in future charges. At December 31, 2025, reinsurance recoverables on paid and unpaid losses from the Company’s five largest reinsurers were $ 95.8 million, $ 46.3 million, $ 37.9 million, $ 30.8 million and $ 24.6 million, representing 59.7 % of the total balance. At December 31, 2025, unearned premiums ceded to five reinsurers were $ 9.8 million, $ 5.3 million, $ 4.7 million, $ 4.5 million and $ 4.0 million representing 63.7 % of the total balance. 97 Table of Contents 9. Stockholders’ equity Capital Stock The Company’s authorized capital stock consists of 400,000,000 shares of common stock, par value $ 0.01 per share, and 100,000,000 shares of preferred stock, par value $ 0.01 per share. There were no shares of preferred stock issued or outstanding at December 31, 2025 or 2024. Treasury Stock In October 2024, the Company's Board of Directors authorized a share repurchase program authorizing the repurchase of up to $ 100.0 million of the Company's common stock. This share repurchase program was exhausted in October 2025. In December 2025, the Company's Board of Directors authorized a new share repurchase program authorizing the repurchase of up to $ 250.0 million of the Company's common stock. The shares may be repurchased from time to time in open market purchases, privately-negotiated transactions, block purchases, accelerated share repurchase agreements or a combination of methods and pursuant to safe harbors provided by Rule 10b-18 and Rule 10b5-1 under the Securities Exchange Act of 1934. The timing, manner, price and amount of any repurchases under the share repurchase program will be determined by the Company in its discretion. The stock repurchase program does not require the Company to repurchase any specific number of shares, and may be modified, suspended or terminated at any time. The cost of treasury stock acquired pursuant to common share repurchases includes the 1% excise tax imposed on common share repurchase activity, net of common share issuances, as part of the Inflation Reduction Act of 2022. The Company recorded excise taxes payable of $ 0.6 million for the year ended December 31, 2025. There were no excise taxes imposed for the year ended December 31, 2024. Equity-based Compensation The Kinsale Capital Group, Inc. 2016 Omnibus Incentive Plan (the "2016 Incentive Plan") was effective from 2016 to 2025. On May 22, 2025, the Company's stockholders approved the Kinsale Capital Group, Inc. 2025 Omnibus Incentive Plan (the "2025 Incentive Plan"), which replaced the 2016 Incentive Plan prior to its scheduled expiration in 2026. The 2025 Incentive Plan is administered by the Compensation, Nominating and Corporate Governance Committee of the Company's Board of Directors and authorizes the grant of stock options, restricted stock, restricted stock units, and other stock-based awards to officers, employees, directors, independent contractors, and consultants. No additional awards will be issued under the 2016 Incentive Plan, and shares remaining available under that plan will not roll forward to the 2025 Incentive Plan. The maximum number of shares of the Company's common stock reserved and available for issuance under the 2025 Incentive Plan is 860,500 plus any shares subject to awards outstanding under the 2016 Incentive Plan as of May 22, 2025 that are subsequently forfeited or settled in cash. There were no shares granted under the 2025 Incentive Plan during the year ended December 31, 2025. The Company recognized total equity-based compensation expense of $ 17.9 million, $ 14.1 million and $ 9.4 million for the years ended December 31, 2025, 2024 and 2023, respectively. Stock Options On July 27, 2016, the Board of Directors approved, and the Company granted, 1,036,916 stock options with an exercise price equal to the initial public offering price of $ 16.00 per share. The options have a maximum contractual term of 10 years and vested in 4 equal annual installments following the date of the grant. The weighted average grant date fair value of options granted during 2016 was $ 2.71 per share. The value of the options granted was estimated at the date of grant using the Black-Scholes pricing model. 98 Table of Contents A summary of option activity as of December 31, 2025 and changes during the year then ended is presented below: Number of Shares Weighted-average exercise price Weighted-average remaining years of contractual life Aggregate intrinsic value (in thousands) Outstanding at December 31, 2024 118,468 $ 16.00 Granted — — Forfeited — — Exercised ( 42,554 ) 16.00 Outstanding at December 31, 2025 75,914 $ 16.00 0.6 $ 28,477 Exercisable at December 31, 2025 75,914 $ 16.00 0.6 $ 28,477 The total intrinsic value of options exercised was $ 18.7 million during the year ended December 31, 2025 and $ 38.2 million during the year ended December 31, 2024. Restricted Stock Awards During 2025, the Board of Directors approved, and the Company granted, restricted stock awards under the 2016 Incentive Plan. The restricted stock awards were valued on the date of grant and will vest over a period of 1 to 4 years corresponding to the anniversary date of the grants. The fair value of restricted stock awards was determined based on the closing trading price of the Company’s common stock on the grant date or, if no common stock was traded on the grant date, the last preceding date for which there was a sale of common stock. Except for restrictions placed on the transferability of restricted stock, holders of unvested restricted stock have full stockholder’s rights, including voting rights and the right to receive cash dividends. Unvested restricted stock awards and accrued dividends, if any, are forfeited upon the termination of service to or employment with the Company. A summary of restricted stock activity under the equity compensation plans for the year ended is as follows: December 31, 2025 Number of Shares Weighted Average Grant Date Fair Value per Share Nonvested outstanding at the beginning of the period 110,123 $ 366.73 Granted 59,963 $ 433.62 Vested ( 43,685 ) $ 322.04 Forfeited ( 2,351 ) $ 390.17 Nonvested outstanding at the end of the period 124,050 $ 414.36 Employees surrender restricted stock awards to pay for withholding tax obligations resulting from any vesting of those awards. During the year ended December 31, 2025, restricted stock awards withheld for taxes in connection with the vesting of those awards totaled 14,536 . The per share weighted average grant-date fair value of the Company's restricted stock awards granted during the years ended December 31, 2025, 2024 and 2023 was $ 433.62 , $ 502.43 and $ 313.35 , respectively.

Basic earnings per share was computed by dividing the earnings attributable to the common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share was computed by dividing earnings attributable to common stockholders by the weighted average number of shares of common stock outstanding during the period, including potentially dilutive shares of common stock for the period determined using the treasury stock method. 11. Debt Note Purchase and Private Shelf Agreement On July 22, 2022, the Company entered into a Note Purchase and Private Shelf Agreement (as subsequently amended, the "Note Purchase Agreement") with PGIM, Inc. ("Prudential") and the purchasers of the Series A and Series B Senior Notes (as defined below). The Note Purchase Agreement provides for issuance of senior promissory notes with an aggregate principal amount of up to $ 200.0 million through September 18, 2026.

The Series A and B Notes are senior unsecured obligations of the Company and rank pari passu with the Company’s Amended and Restated Credit Agreement. Principal payments on the Series A Notes are required annually beginning on July 22, 2030 in equal installments of $ 25.0 million through July 22, 2034 . Principal payments on the Series B Note are required annually beginning on July 22, 2030 in equal installments of $ 10.0 million through July 22, 2034 . 100 Table of Contents Credit Agreement On July 22, 2022, the Company entered into an Amended and Restated Credit Agreement (as amended, the "Credit Agreement"), with JPMorgan Chase Bank, N.A., as administrative agent and as issuing bank, Truist Bank, as syndication agent, and the lenders party thereto (collectively, the "Lenders"). The Amended and Restated Credit Agreement provides the Company with a $ 100.0 million senior unsecured revolving credit facility (the "Credit Facility"), with the option to increase the aggregate commitment by $ 30.0 million. The Company is required to pay a Commitment Fee Rate (as defined therein) of 0.25 % on the average daily amount of the Available Revolving Commitment (as defined therein). Borrowings under the Credit Agreement may be used for general corporate purposes (which may include, without limitation, to fund future growth, to finance working capital needs, to fund capital expenditures, and to refinance, redeem or repay indebtedness). During the year ended December 31, 2025, the Company drew down $ 40.0 million from the Credit Facility. The loans under the Amended and Restated Credit Agreement bear interest, at the Company's option, at a rate equal to the Adjusted Term SOFR Rate (as defined therein) plus 1.625% or the Alternate Base Rate (as defined therein) plus 0.625%. For the year ended December 31, 2025, the annual weighted-average interest rate of borrowings under the Credit Facility was 5.83 %. The following table presents the Company's outstanding debt as of December 31, 2025 and 2024: Issuance Maturities December 31, 2025 December 31, 2024 (in thousands) Credit Facility Various 7/22/2027 $ 51,000 $ 11,000 5.15 % Series A Notes 7/22/2022 7/22/2034 125,000 125,000 6.21 % Series B Note 9/18/2023 7/22/2034 50,000 50,000 Less: Unamortized debt issuance costs ( 1,603 ) ( 1,878 ) Total debt $ 224,397 $ 184,122 Interest paid under both agreements totaled $ 10.4 million, $ 10.3 million and $ 10.5 million for the years ended December 31, 2025, 2024 and 2023, respectively.

In December 2025, the covenants limiting restricted payments under the Note Purchase Agreement and Amended and Restated Credit Agreement were amended to allow the Company to make restricted payments so long as at the time of the declaration of such restricted payment, no event of default under the Note Purchase Agreement has occurred and is continuing or would arise after giving effect, on a pro forma basis, to such restricted payment if such restricted payment were to be made at such time of declaration. As of December 31, 2025, the Company was in compliance with all of its financial covenants under both the Note Purchase Agreement and the Credit Facility. 101 Table of Contents 12. Contingencies Contingencies arise in the normal conduct of the Company’s operations and are not expected to have a material effect on the Company’s financial condition or results of operations. However, adverse outcomes are possible and could negatively affect the Company’s financial condition and results of operations. In June 2019, Marie Hughes, as authorized administrator for the estate of George Hughes, filed a wrongful death claim against Venetian Hills Apartments, LLC ("Venetian Hills") in DeKalb County in Georgia state court. On December 20, 2023, the jury awarded a verdict to the plaintiff of $140 million. On October 31, 2025, the Georgia Court of Appeals vacated the $140 million judgment and ordered a full retrial after it found that the trial court incorrectly charged the jury on the applicable law. On December 29, 2025, the plaintiff filed a petition requesting that the Georgia Supreme Court review the Georgia Court of Appeal’s decision. The Georgia Supreme Court has the discretion to either accept or deny the Plaintiff’s request to hear the case. Venetian Hills was a policyholder of a $1 million general liability policy issued by Kinsale Insurance. The Company believes exclusions in the policy apply to the claim and intends to defend any action related to this proceeding vigorously. The Company does not expect a resolution as to the Company’s liability, if any, with respect to this matter in the foreseeable future, and potentially for multiple years. The Company does not believe this legal proceeding will have a material adverse effect on its results of operations or business. The Company believes adequate provision has been made in its consolidated financial statements and its existing reserves account for liabilities to the Company relating to claims such as this legal proceeding. 13. Employee benefit plan The Company has established a defined contribution employee retirement plan ("Plan") in accordance with Section 401(k) of the Internal Revenue Code. Expenses related to the Plan were $ 5.8 million, $ 5.0 million and $ 3.8 million in 2025, 2024 and 2023, respectively. 102 Table of Contents 14.

The related tax effect of the reclassification adjustment is recorded in income tax expense in current period earnings. See Note 2 for additional information. 15. Segment and underwriting information The Company has one reportable segment, the Excess and Surplus Lines Insurance segment, which primarily offers commercial excess and surplus lines liability and property insurance products through its underwriting divisions in the United States. The Company reports operating and financial results in a single segment based on the Company's exclusive focus on property and casualty insurance in the excess and surplus lines market and the consolidated information used by the chief operating decision maker ("CODM") in evaluating the financial performance of its business and allocating resources. The Company's CODM is the Chief Executive Officer. The CODM uses consolidated net income to allocate resources primarily during the annual budgeting process and uses that measure to assess performance by considering budget-to-actual variances and evaluating financial results. The measure of segment assets is reported on the consolidated balance sheets as total assets. The accounting policies used to prepare the segment reporting data are the same as those described in Note 1. 103 Table of Contents Year Ended December 31, 2025 2024 2023 (in thousands) Revenues: Net earned premiums $ 1,575,842 $ 1,350,470 $ 1,072,537 Fee income 40,714 34,118 27,026 Net investment income 192,192 150,287 102,335 Change in fair value of equity securities 58,836 43,367 15,277 Net realized investment gains 4,390 6,831 6,040 Change in allowance for credit losses on investments ( 2 ) 526 ( 187 ) Other income (1) 2,015 1,926 1,421 Total revenues 1,873,987 1,587,525 1,224,449 Expenses: Losses and loss adjustment expenses - current year 923,160 785,036 631,407 Losses and loss adjustment expenses - catastrophes 30,350 25,518 4,586 Losses and loss adjustment expenses - prior year development ( 62,817 ) ( 37,655 ) ( 35,774 ) Net commissions incurred 166,802 134,184 113,717 Salaries, employee benefits and bonus expense 128,917 109,319 85,689 Credit loss expense - premiums receivable 10,503 17,397 9,790 Depreciation (2) 4,777 4,686 2,655 Interest expense 10,646 10,134 10,301 Other segment items (3) 27,347 24,190 18,061 Income tax expense 130,688 99,873 75,924 Segment net income 503,614 414,843 308,093 Reconciliation of profit or loss: Adjustments and reconciling items — — — Consolidated net income $ 503,614 $ 414,843 $ 308,093 (1) Other income primarily includes income generated from the Company's real estate operations.

In converting from statutory accounting principles to U.S. GAAP, typical adjustments include deferral of policy acquisition costs, the inclusion of statutory non-admitted assets and the inclusion of net unrealized gains or losses relating to fixed maturities in stockholders’ equity. The Company does not use any permitted practices that are different from prescribed statutory accounting practices. Statutory net income and statutory capital and surplus for Kinsale Insurance as of December 31, 2025, 2024, and 2023 and for the years then ended are summarized as follows: Year ended December 31, 2025 2024 2023 (in thousands) Statutory net income $ 447,965 $ 357,896 $ 259,042 Statutory capital and surplus $ 1,933,169 $ 1,525,851 $ 1,167,382 Kinsale Insurance is subject to risk-based capital ("RBC") requirements. RBC is a method developed by the National Association of Insurance Commissioners ("NAIC") to determine the minimum amount of statutory capital appropriate for an insurance company to support its overall business operations in consideration of its size and risk profile. The formula for determining the amount of RBC is calculated using various factors, weighted based on the perceived degree of risk, which are applied to certain financial balances and financial activity. The adequacy of a company’s actual capital is evaluated by a comparison to the RBC results, as determined by the formula. Companies that do not maintain statutory capital and surplus at a level in excess of the company action level RBC are required to take specified actions. At December 31, 2025 and 2024, actual statutory capital and surplus for Kinsale Insurance substantially exceeded the regulatory requirements. Dividend payments to Kinsale from Kinsale Insurance are restricted by state insurance laws as to the amount that may be paid without prior approval of the regulatory authorities of Arkansas. The maximum dividend distribution is limited by Arkansas law to the greater of 10 % of policyholder surplus as of December 31 of the previous year or statutory net income, not including realized capital gains, for the previous calendar year. Dividend payments are further limited to that part of available policyholder surplus which is derived from net profits on its business. The maximum dividend distribution that can be paid by Kinsale Insurance during 2026 without prior approval is $ 444.3 million. 107 Table of Contents Schedule I KINSALE CAPITAL GROUP, INC.

(the "Company"), a Delaware domiciled insurance holding company, was formed on June 3, 2009 for the purpose of acquiring and managing insurance entities. Basis of presentation The accompanying condensed financial statements have been prepared using the equity method.

These condensed financial statements should be read in conjunction with the Company’s consolidated financial statements. Estimates and assumptions Preparation of the condensed financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed financial statements and accompanying disclosures. Those estimates are inherently subject to change, and actual results may ultimately differ from those estimates.

("Prudential") and the purchasers of the Series A and Series B Senior Notes (as defined below). The Note Purchase Agreement provides for issuance of senior promissory notes with an aggregate principal amount of up to $ 200.0 million through September 18, 2026.

Principal payments on the Series B Note are required annually beginning on July 22, 2030 in equal installments of $ 10.0 million through July 22, 2034 .

The Amended and Restated Credit Agreement provides the Company with a $ 100.0 million senior unsecured revolving credit facility (the "Credit Facility"), with the option to increase the aggregate commitment by $ 30.0 million. The Company is required to pay a Commitment Fee Rate (as defined therein) of 0.25 % on the average daily amount of the Available Revolving Commitment (as defined therein). Borrowings under the Amended and Restated Credit Agreement may be used for general corporate purposes (which may include, without limitation, to fund future growth, to finance working capital needs, to fund capital expenditures, and to refinance, redeem or repay indebtedness). During the year ended December 31, 2025, the Company drew down $ 40.0 million from the Credit Facility. The loans under the Amended and Restated Credit Agreement bear interest, at the Company's option, at a rate equal to the Adjusted Term SOFR Rate (as defined therein) plus 1.625% or the Alternate Base Rate (as defined therein) plus 0.625%. For the year ended December 31, 2025, the annual weighted-average interest rate of borrowings under the Credit Facility was 5.83 %.
