Kinsale Capital Group, Inc.

1. Summary of Significant Accounting Policies

Basis of presentation

The unaudited condensed consolidated financial statements and notes have been prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") for interim financial information and do not contain all of the information and footnotes required by U.S. GAAP for complete financial statements. As such, these unaudited condensed consolidated interim financial statements should be read in conjunction with the audited consolidated financial statements of Kinsale Capital Group, Inc. and its subsidiaries ("the Company") included in the Annual Report on Form 10-K for the year ended December 31, 2024. In the opinion of management, all adjustments necessary for a fair presentation of the condensed consolidated financial statements have been included. Such adjustments consist only of normal recurring items. All significant intercompany balances and transactions have been eliminated in consolidation. Interim results are not necessarily indicative of results of operations for the full year.

Use of estimates

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, if any, 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 those estimates.

Recently adopted accounting pronouncements

Accounting Standards Update ("ASU") 2023-07, Segment Reporting - Improvements to Reportable Segment Disclosures

In November 2023, the Financial Accounting Standards Board ("FASB") issued ASU 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures," which expands reportable segment disclosure requirements by requiring disclosures of significant reportable segment expenses that are regularly provided to the Chief Operating Decision Maker ("CODM") and included within each reported measure of a segment's profit or loss. The ASU also requires disclosure of the title and position of the individual identified as the CODM and an explanation of how the CODM uses the reported measures of a segment's profit or loss in assessing segment performance and deciding how to allocate resources. Additionally, ASU 2023-07 requires all segment profit or loss and assets disclosures to be provided on an annual and interim basis. ASU 2023-07 became effective for the Company for the year ended December 31, 2024 and is effective for interim periods within 2025. Refer to Note 15 for the Company's segment reporting disclosures.

Prospective accounting pronouncements

ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures

In November 2024, the FASB issued ASU 2024-03, "Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses," requiring public entities to disclose additional information about specific expense categories in the notes to the financial statements on an interim and annual basis. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and for interim periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the effect the guidance will have on its disclosures.

2. Investments

Available-for-sale investments

The following tables summarize the available-for-sale investments at March 31, 2025 and December 31, 2024:

Available-for-sale securities in a loss position

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. 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 decline 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 its 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.

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 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 available-for-sale investments 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.

At March 31, 2025, the Company's credit loss review resulted in an allowance for credit losses onfour securities. The following table presents changes in the allowance for expected credit losses on available-for-sale securities for the three months ended March 31, 2025 and 2024:

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:

At March 31, 2025, the Company held 848 fixed-maturity securities in an unrealized loss position with a total estimated fair value of $1.6 billion and gross unrealized losses of $113.8 million. Of these securities,593 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 March 31, 2025, except for securities previously discussed, unrealized losses were caused by interest rate changes or other market factors and were not credit-specific issues. At March 31, 2025,79.7% of the Company’s fixed-maturity securities were rated "A-" or better and all of the Company’s fixed-maturity securities made expected coupon payments under the contractual terms of the securities.

Contractual maturities of available-for-sale fixed-maturity securities

The amortized cost and estimated fair value of available-for-sale fixed-maturity securities at March 31, 2025 are summarized, by contractual maturity, as follows:

Expected maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties, and the lenders may have the right to put the securities back to the borrower.

Real estate investments

Real estate investments represents directly owned property held for investment purposes and consisted of land with a carrying value of $15.0 million at March 31, 2025 and December 31, 2024, respectively. There wasno accumulated depreciation on real estate investments at March 31, 2025 and December 31, 2024.

Net investment income

The following table presents the components of net investment income for the three months ended March 31, 2025 and 2024:

There wasno depreciation expense related to real estate investments for the three months ended March 31, 2025 or three months ended March 31, 2024 as the Company sold the related assets during 2023.

Realized investment gains and losses

The following table presents realized investment gains and losses for the three months ended March 31, 2025 and 2024:

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. The change in unrealized gains (losses) in the consolidated statement of income consists of two components: (1) the reversal of the gain or loss recognized in previous periods on equity securities sold and (2) the change in unrealized gain or loss resulting from mark-to-market adjustments on equity securities still held.

Change in net unrealized gains (losses) on fixed-maturity securities

For the three months ended March 31, 2025 and 2024, the change in net unrealized gains (losses) for fixed-maturity securities was $33.4 million and $(12.6) million, respectively.

Insurance – statutory deposits

The Company had invested assets with a fair value of $3.9 million and $3.7 million on deposit with state regulatory authorities at March 31, 2025 and December 31, 2024, respectively.

Payable for investments purchased

The Company recorded a payable for investments purchased, not yet settled, of $37.7 million at March 31, 2025. The Company didnot have a payable for investments purchased at December 31, 2024, respectively. The payable balance was included in the "other liabilities" line item of the consolidated balance sheet.

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.

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 condensed consolidated financial statements, 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 March 31, 2025 and December 31, 2024, by level within the fair value hierarchy:

There were no assets or liabilities measured at fair value on a nonrecurring basis as of March 31, 2025 or December 31, 2024.

The carrying amount of the Company's fixed-rate senior notes was $175.0 million, less debt issuance costs, and the corresponding estimated fair value was $170.4 million and $168.6 million at March 31, 2025 and December 31, 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 March 31, 2025 and December 31, 2024. See Note 13 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 $56.1 million and $16.1 million at March 31, 2025 and December 31, 2024, respectively.

4. Allowance for Credit Losses

Premiums receivable

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 change in the allowance for credit losses for premiums receivable for the three months ended March 31, 2025 and 2024:

5. Deferred Policy Acquisition Costs

The following table presents the amounts of policy acquisition costs deferred and amortized for the three months ended March 31, 2025 and 2024:

Amortization of net policy acquisition costs is included in the line item "underwriting, acquisition and insurance expenses" in the accompanying consolidated statements of income and comprehensive income.

6. Property and Equipment, Net

Property and equipment are included in "other assets" in the accompanying consolidated balance sheets and consist of the following:

Construction in progress includes capitalized expenses related to the development of the new corporate headquarters' building. Construction is expected to be completed in the fourth quarter of 2025.

7. Underwriting, Acquisition and Insurance Expenses

Underwriting, acquisition and insurance expenses for the three months ended March 31, 2025 and 2024 consist of the following:

Other underwriting expenses within underwriting, acquisition and insurance expenses include salaries, bonus and employee benefits expenses of $29.2 million and $24.7 million for the three months ended March 31, 2025 and 2024, respectively.

8. Stock-based Compensation

On July 27, 2016, the Kinsale Capital Group, Inc. 2016 Omnibus Incentive Plan (the "2016 Incentive Plan") became effective. The 2016 Incentive Plan, which is administered by the Compensation, Nominating and Corporate Governance Committee of the Company’s Board of Directors, provides for grants of stock options, restricted stock, restricted stock units and other stock-based awards to officers, employees, directors, independent contractors and consultants. The number of shares of common stock available for issuance under the 2016 Incentive Plan may not exceed 2,073,832.

The total compensation cost that has been charged against income for share-based compensation arrangements was $3.8 million and $3.5 million for the three months ended March 31, 2025 and 2024, respectively.

Restricted Stock Awards

During the three months ended March 31, 2025, 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 shares on the grant date or, if no shares were traded on the grant date, the last preceding date for which there was a sale of shares. 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 dividends. Unvested shares of 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 2016 Incentive Plan for the three months ended March 31, 2025 is as follows:

Employees surrender shares to pay for withholding tax obligations resulting from any vesting of restricted stock awards. During the three months ended March 31, 2025, shares withheld for taxes in connection with the vesting of restricted stock awards totaled 14,467.

The weighted average grant-date fair value per share of the Company's restricted stock awards granted during the three months ended March 31, 2025 and 2024 was $433.62 and $502.54, respectively. The fair value of restricted stock awards that vested during the three months ended March 31, 2025 and 2024 was $18.7 million and $16.9 million, respectively. As of March 31, 2025, the Company had $50.0 million of total unrecognized stock-based compensation expense expected to be charged to earnings over a weighted-average period of 3.0 years.

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 and a weighted-average grant-date fair value of $2.71 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 value of the options granted was estimated at the date of grant using the Black-Scholes pricing model.

A summary of option activity as of March 31, 2025, and changes during the period then ended are presented below:

The total intrinsic value of options exercised was $6.3 million and $28.1 million during the three months ended March 31, 2025 and 2024, respectively.

9. Earnings Per Share

The following represents a reconciliation of the numerator and denominator of the basic and diluted earnings per share computations contained in the condensed consolidated financial statements:

There were 89,000 and 44,000 anti-dilutive stock awards for the three months ended March 31, 2025 and 2024, respectively.

10. Income Taxes

The Company uses the estimated annual effective tax rate method for calculating its tax provision in interim periods, which represents the Company's best estimate of the effective tax rate expected for the full year. The estimated annual effective tax rate typically differs from the U.S. statutory tax rate, primarily as a result of tax-exempt investment income and any discrete items recognized during the period. The Company's effective tax rates were 20.6% and 14.6% for the three months ended March 31, 2025 and 2024, respectively, and were lower than the federal statutory rate of 21% due primarily to the tax benefits from stock-based compensation, including stock options exercised, and from income generated by certain tax-exempt investments. The effective tax rate was higher for the three months ended March 31, 2025 due primarily to a lower volume of stock options exercised compared to the same period in 2024.

11. Reserves For Unpaid Losses and Loss Adjustment Expenses

The following table presents a reconciliation of consolidated beginning and ending reserves for unpaid losses and loss adjustment expenses:

During the three months ended March 31, 2025, the reserves for unpaid losses and loss adjustment expenses held at December 31, 2024 developed favorably by $14.6 million, of which $16.7 million was attributable to the 2021 through 2024 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 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 three months ended March 31, 2025 included $22.6 million of net catastrophe losses primarily related to the Palisades Fire.

During the three months ended March 31, 2024, the reserves for unpaid losses and loss adjustment expenses held at December 31, 2023 developed favorably by $8.4 million, of which $16.3 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 2018 and 2019 accident years due to construction defect claims and from the 2020 accident year due to a large property claim.

12. Reinsurance

The following table summarizes the effect of reinsurance on premiums written and earned for the three months ended March 31, 2025 and 2024:

The following table summarizes ceded losses and loss adjustment expenses for the three months ended March 31, 2025 and 2024:

The following table presents reinsurance recoverables on paid and unpaid losses as of March 31, 2025 and December 31, 2024:

13. 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.

Pursuant to the Note Purchase Agreement, on July 22, 2022, the Company issued $125.0 million aggregate principal amount of 5.15% Series A Senior Notes Due July 22, 2034 (collectively, the "Series A Notes"), and on September

18, 2023, the Company issued a $50.0 million aggregate principal amount 6.21% Series B Senior Note ("Series B Note") due July 22, 2034.

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.

Credit Agreement

On July 22, 2022, the Company entered into an Amended and Restated 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 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).

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 three months ended March 31, 2025, the annual weighted-average interest rate of borrowings under the Credit Facility was 6.1%.

The following table presents the Company's outstanding debt as of March 31, 2025 and December 31, 2024:

Both the Note Purchase Agreement and the Amended and Restated Credit Agreement contain representations and affirmative and negative covenants, including financial covenants customary for agreements of this type, as well as customary events of default provisions. As of March 31, 2025, the Company was in compliance with all of its financial covenants under both the Note Purchase Agreement and the Credit Facility.

In October 2024, the covenants limiting restricted payments under the Note Purchase Agreement and Amended and Restated Credit Agreement were amended. The amendments allow the Company to make restricted payments so long as the aggregate amount of all such restricted payments does not exceed the greater of $300.0 million and 6.5% of the total assets of the Company and its subsidiaries at the end of the most recently completed fiscal quarter.

14. Other Comprehensive Income (Loss)

The following table summarizes the components of other comprehensive income (loss) for the three months ended March 31, 2025 and 2024:

The sale or credit loss of an available-for-sale fixed-maturity security results in amounts being reclassified from accumulated other comprehensive income (loss) to realized gains or losses in current period earnings. 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 information

The Company hasone 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.

(1) Other income primarily includes income generated from the Company's real estate operations.

(2) Excludes depreciation expense allocated to loss adjustment expenses and investment expenses

(3) Other segment items primarily includes other general and administrative expenses such as technology costs, facility expenses and audit and inspection costs.

16. 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 $140.0 million.

Venetian Hills was a policyholder of a $1.0 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 has begun the appeal process and 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.
