NOTES TO UNAUDITED INTERIM CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. Basis of Presentation
The words "Company," "we," "us," or "our" refer to Selective Insurance Group, Inc. (the "Parent") and its subsidiaries, except as expressly indicated or the context requires otherwise. We have prepared our interim unaudited consolidated financial statements ("Financial Statements") in conformity with (i) United States ("U.S.") generally accepted accounting principles ("GAAP"), and (ii) the rules and regulations of the U.S. Securities and Exchange Commission ("SEC") regarding interim financial reporting. These require management to make estimates and assumptions that affect the reported financial statement balances and the disclosure of contingent assets and liabilities. Actual results could differ from those estimates. All significant intercompany accounts and transactions are eliminated in consolidation.

Our Financial Statements reflect all adjustments that, in our opinion, are normal, recurring, and necessary for a fair presentation of our results of operations and financial condition. Our Financial Statements cover the third quarters ended September 30, 2025 ("Third Quarter 2025") and September 30, 2024 ("Third Quarter 2024"), and the nine-month periods ended September 30, 2025 ("Nine Months 2025") and September 30, 2024 ("Nine Months 2024"). Our Financial Statements do not include all information and disclosures required by GAAP and the SEC for audited annual financial statements. Because interim period results of operations are not necessarily indicative of full-year results, our Financial Statements should be read in conjunction with the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2024 ("2024 Annual Report") filed with the SEC.

NOTE 2. Adoption of Accounting Pronouncements
We adopted no accounting pronouncements in Nine Months 2025.

Pronouncements to be effective in the future
In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures ("ASU 2023-09"). ASU 2023-09 amends disclosure requirements to provide greater transparency on income taxes. The following additional disclosures are required annually: (i) specific required categories in the rate reconciliation, (ii) additional information for reconciling items that meet a quantitative threshold, (iii) the amount of income taxes paid disaggregated by jurisdiction, and (iv) income tax expense (or benefit) from continuing operations disaggregated by federal, state, and foreign. ASU 2023-09 is effective for annual periods beginning after December 15, 2024. Amendments can be applied prospectively. Retrospective application and early adoption are permitted. As it only requires additional disclosure, ASU 2023-09 will not have a material impact on our financial condition or results of operations.

In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses ("ASU 2024-03"). ASU 2024-03 requires disaggregated disclosure of income statement expenses. This ASU does not change the expense captions on the income statement; rather, it requires disaggregation of certain expense captions into specified categories in disclosures within the footnotes to the financial statements. ASU 2024-03 is effective for annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. This ASU can be applied prospectively. Retrospective application and early adoption are permitted. As ASU 2024-03 only requires additional disclosure, it will not have a material impact on our financial condition and results of operations.

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

During Nine Months 2025 and Nine Months 2024, we had no write-offs or recoveries of our AFS fixed income securities.

For information on our methodology and significant inputs used to measure expected credit losses, our accounting policy for recognizing write-offs of uncollectible amounts, and our treatment of accrued interest, refer to Note 2. "Summary of Significant Accounting Policies" in Item 8. "Financial Statements and Supplementary Data." of our 2024 Annual Report. Accrued interest on AFS securities was $ 84.0 million as of September 30, 2025, and $ 74.3 million as of December 31, 2024. We did not record any material write-offs of accrued interest in Nine Months 2025 and Nine Months 2024.

We currently do not intend to sell any of the securities summarized in the tables above, nor do we believe we will be required to sell any of them. The decrease in gross unrealized losses at September 30, 2025, compared to December 31, 2024, was primarily driven by a decrease in benchmark U.S. Treasury rates. Considering these factors and our review of these securities under our credit loss policy as described in Note 2. "Summary of Significant Accounting Policies" in Item 8. "Financial Statements and Supplementary Data." of our 2024 Annual Report, we have concluded that no additional allowance for credit loss is required on these balances beyond the allowance for credit loss recorded as of September 30, 2025. This conclusion reflects our current judgment about the financial position and future prospects of the entities that issued the investment security and underlying collateral.

The quantitative details of these unobservable inputs are neither provided to us, nor reasonably available to us, and therefore are not included in the tables above.

For the securities in the tables above valued using a discounted cash flow analysis, we apply an illiquidity spread in determining fair value. An increase in this assumption would result in a lower fair value measurement.

NOTE 9. Segment Information
We evaluate the results of our four reportable segments as follows:

Our Standard Commercial Lines, Standard Personal Lines, and E&S Lines are evaluated on (i) before and after-tax underwriting results (net premiums earned, incurred loss and loss expense, policyholder dividends, policy acquisition costs, and other underwriting expenses), (ii) their return on equity ("ROE") contribution, and (iii) their combined ratios.

Our Investments segment is primarily evaluated on after-tax net investment income and its ROE contribution. After-tax net realized and unrealized gains and losses are also included in our Investments segment results.

In computing each segment's results, we do not make adjustments for interest expense or corporate expenses. No segment has a separate investment portfolio or allocated assets.

NOTE 10. Retirement Plans
The primary pension plan for our employees is the Retirement Income Plan for Selective Insurance Company of America (the "Pension Plan"). The Pension Plan is closed to new entrants, and its benefits ceased accruing after March 31, 2016. For more information about Selective Insurance Company of America's ("SICA") retirement plans, see Note 15. "Retirement Plans" in Item 8. "Financial Statements and Supplementary Data." of our 2024 Annual Report.

Short-Term Debt Activity
On June 30, 2025, the Parent entered into a Credit Agreement (the "Line of Credit") with the lenders named therein (the "Lenders") and Wells Fargo Bank, National Association, as administrative agent. Under the Line of Credit, the Lenders have agreed to provide the Parent with a $ 100 million revolving credit facility that can be increased to $ 200 million with the Lenders' consent. The Line of Credit will mature on June 30, 2028, and has a variable interest rate based on the Parent’s debt ratings. The Parent, as borrower, was a party to a credit agreement dated November 7, 2022, for a $ 50 million revolving credit facility, which could be increased to $ 125 million with the consent of the lenders (the "Prior Credit Agreement"). The Prior Credit Agreement was scheduled to mature on November 7, 2025. The Parent terminated the Prior Credit Agreement in conjunction with entering into the Line of Credit. The termination of the Prior Credit Agreement did not result in any penalties to the Parent. There were no borrowings under the Line of Credit or the Prior Credit Agreement during Nine Months 2025.

26

Our Line of Credit contains representations, warranties, and covenants that are customary for credit facilities of this type, including, without limitation, financial covenants under which we are obligated to maintain a minimum consolidated net worth, a maximum ratio of consolidated debt to total capitalization, and covenants limiting our ability to: (i) merge or liquidate; (ii) incur debt or liens; (iii) dispose of assets; (iv) make investments and acquisitions; and (v) engage in transactions with affiliates.

The table below outlines information regarding certain covenants in the Line of Credit:

Required as of Actual as of
September 30, 2025 September 30, 2025
Consolidated net worth 1
Not less than $ 2.4 billion $ 3.7 billion
Debt to total capitalization ratio 1
Not to exceed 35 % 19.8 %
1 Calculated in accordance with the Line of Credit.

In addition to the above requirements, the Line of Credit contains a cross-default provision that provides that the Line of Credit will be in default if we fail to comply with any condition, covenant, or agreement (including payment of principal and interest when due on any debt with an aggregate principal amount of at least $ 30 million) that causes or permits the acceleration of principal. The Line of Credit also limits borrowings from the FHLBI and the FHLBNY to 10 % of the respective member company's admitted assets for the previous year.

Long-Term Debt Activity
In the first quarter of 2025, we issued $ 400 million of 5.90 % Senior Notes due 2035 at a discount of $ 0.1 million, resulting in $ 395.9 million of net proceeds after debt issuance costs of approximately $ 4.1 million. The 5.90 % Senior Notes will pay interest on April 15 and October 15 of each year, beginning on October 15, 2025. The proceeds from this debt issuance are being used for general corporate purposes, including supporting organic growth.

For additional information on our indebtedness and debt covenants, see Note 11. "Indebtedness" in Item 8. "Financial Statements and Supplementary Data." of our 2024 Annual Report.

NOTE 13. Equity
On December 2, 2020, we announced that our Board of Directors authorized a $ 100 million share repurchase program, with no set expiration or termination date. Our repurchase program does not obligate us to acquire any particular common stock amount. The program grants management discretion to determine the timing and amount of any share repurchases under the authorization based on market conditions and other considerations. In Nine Months 2025, we repurchased 698,312 shares of our common stock under the program. The cost of these repurchases was $ 55.6 million, including commissions. Authorized repurchases reflected in the Consolidated Statement of Stockholders' equity also included estimated excise tax of $ 0.3 million in Nine Months 2025. We had $ 19.9 million of remaining program capacity as of September 30, 2025.

On October 22, 2025, the Company announced that its Board of Directors authorized a new share repurchase program under which the Company may repurchase issued and outstanding shares of common stock up to $ 200 million, exclusive of any excise tax impact. This program is effective on October 27, 2025 and has no expiration date. The Company’s existing share repurchase program remained effective through October 24, 2025.

NOTE 15. Federal Income Taxes
On July 4, 2025, the One Big Beautiful Bill Act (the "Act") became law. The legislation is extensive, and some changes will affect our taxes in current and future years. The tax law changes are reflected in the enactment period, which is Third Quarter 2025. We have analyzed the Act's major impacts, which include provisions that allow 100% bonus depreciation for certain qualified assets and full deduction of domestic research and development expenditures. Both are temporary differences and do not impact total tax expense but provide a cash tax benefit that is estimated at $ 6.4 million for the 2025 tax year.

NOTE 16. Litigation
As of September 30, 2025, we do not believe we are involved in any legal action that could have a material adverse effect on our consolidated financial condition, results of operations, or cash flows.

In the ordinary course of conducting business, we are parties in various legal actions. Most are claims litigation involving our ten insurance subsidiaries (collectively referred to as "Insurance Subsidiaries") as (i) liability insurers defending or providing indemnity for third-party claims brought against our customers, (ii) insurers defending first-party coverage claims brought against them, or (iii) liability insurers seeking declaratory judgment on our insurance coverage obligations. We account for such activity by establishing unpaid loss and loss expense reserves. Considering potential losses and defense costs reserves, we expect that any potential ultimate liability for ordinary course claims litigation will not be material to our consolidated financial condition, results of operations, or cash flows.

From time to time, our Insurance Subsidiaries are named as defendants in other legal actions, some asserting claims for substantial amounts. Plaintiffs may style these actions as class actions and seek judicial certification of a state or national class for allegations involving our business practices, such as improper medical provider reimbursement under workers compensation and personal and commercial automobile insurance policies or improper reimbursement for automobile parts. Similarly, our Insurance Subsidiaries can be named defendants in individual actions seeking extra-contractual damages, punitive damages, or penalties, often alleging bad faith in handling insurance claims. We believe we have valid defenses to these allegations and account for such activity by establishing unpaid loss and loss expense reserves. Considering estimated losses and defense costs reserves, we expect that any potential ultimate liability for these other legal actions will not be material to our consolidated financial condition. Litigation outcomes are inherently unpredictable and the amounts sought in certain actions are large or indeterminate. Adverse outcomes could have a material adverse effect on our consolidated results of operations or cash flows in the quarterly or annual period in which they occur.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

Forward-Looking Statements
The terms "Company," "we," "us," and "our" refer to Selective Insurance Group, Inc. (the "Parent") and its subsidiaries, except as expressly indicated or the context otherwise requires. Certain statements in this Quarterly Report on Form 10-Q, including information incorporated by reference, are “forward-looking statements” defined in the Private Securities Litigation Reform Act of 1995 ("PSLRA"). The PSLRA provides a forward-looking statement safe harbor under the Securities Act of 1933 and the Securities Exchange Act of 1934. These statements discuss our intentions, beliefs, projections, estimations, or forecasts of future events and financial performance. They involve uncertainties, known and unknown risks, and other factors that may cause actual results, activity levels, or performance to materially differ from those in or implied by the forward-looking statements. Forward-looking statements generally include words including or comparable to "may," "will," "could," "would," "should," "expect," "plan," "anticipate," "attribute," "confident," "strong," "target," "project," "intend," "believe," "estimate," "predict," "potential," "pro forma," "seek," "likely," or "continue." Our forward-looking statements are only predictions; we cannot guarantee or assure that such expectations will prove correct. We undertake no obligation to publicly update or revise any forward-looking statements for any reason except as may be required by law.

We discuss the factors that could cause our actual results to differ materially from our projections, forecasts, or estimates in forward-looking statements in Item 1A. "Risk Factors." in Part II. "Other Information" of this Form 10-Q. These risk factors may not be exhaustive. We operate in a constantly changing business environment, and new risk factors may emerge at any time. We cannot predict these new risk factors, their impact on our businesses, or the extent to which one or any combination of factors may cause actual results to differ materially from any forward-looking statements. Given these risks, uncertainties, and assumptions, the forward-looking events we discuss might not occur.

Introduction
We classify our business into four reportable segments:

Standard Commercial Lines;
Standard Personal Lines;
Excess and Surplus Lines ("E&S Lines"); and
Investments.

For more details about these segments, refer to Note 9. "Segment Information" in Item 1. "Financial Statements." of this Form 10-Q and Note 12. "Segment Information" in Item 8. "Financial Statements and Supplementary Data." of our Annual Report on Form 10-K for the year ended December 31, 2024 ("2024 Annual Report").

We write our Standard Commercial and Standard Personal Lines products and services through nine of our insurance subsidiaries, some of which participate in the federal government's National Flood Insurance Program's ("NFIP") Write Your Own Program. We write our E&S products through another subsidiary, Mesa Underwriters Specialty Insurance Company, a nationally authorized non-admitted carrier for customers who generally cannot obtain coverage in the standard marketplace. Collectively, we refer to our ten insurance subsidiaries as the "Insurance Subsidiaries."

The following is Management’s Discussion and Analysis ("MD&A") of our financial condition and consolidated results of operations, including an evaluation of the amounts and certainty of cash flows from operations and outside sources, trends, and uncertainties that may have a material impact in future periods. Investors should read the MD&A in conjunction with Item 1. "Financial Statements." of this Form 10-Q and the consolidated financial statements in our 2024 Annual Report filed with the United States ("U.S.") Securities and Exchange Commission.

In the MD&A, we will discuss and analyze the following:

Critical Accounting Policies and Estimates;
Financial Highlights of Results for the third quarters ended September 30, 2025 ("Third Quarter 2025") and September 30, 2024 ("Third Quarter 2024"); and the nine-month periods ended September 30, 2025 ("Nine Months 2025") and September 30, 2024 ("Nine Months 2024");
Results of Operations and Related Information by Segment;
Federal Income Taxes;
Liquidity and Capital Resources; and
Ratings.

29

Critical Accounting Policies and Estimates
Our unaudited interim consolidated financial statements include amounts for which we have made informed estimates and judgments for transactions not yet completed. Such estimates and judgments affect the reported amounts in the consolidated financial statements. As outlined in our 2024 Annual Report, those estimates and judgments most critical to the preparation of the consolidated financial statements involved the following: (i) reserve for loss and loss expense; (ii) investment valuation and the allowance for credit losses on available-for-sale ("AFS") fixed income securities; and (iii) reinsurance. These estimates and judgments require our use of assumptions about highly uncertain matters that make them subject to change as facts and circumstances develop. If we applied different estimates and judgments, the financial statements might have reported materially different amounts. For additional information regarding our critical accounting policies and estimates, refer to pages 38 through 45 of our 2024 Annual Report.

2 Non-GAAP operating income (loss), non-GAAP operating income (loss) per diluted common share, and non-GAAP operating ROE are comparable to net income (loss) available to common stockholders, net income (loss) available to common stockholders per diluted common share, and ROE, respectively, but exclude after-tax net realized and unrealized gains and losses on investments included in net income (loss). Adjusted book value per common share is comparable to book value per common share, but excludes total after-tax unrealized gains and losses on investments included in accumulated other comprehensive income (loss). These non-GAAP measures are important financial measures used by us, analysts, and investors because the timing of realized and unrealized investment gains and losses on securities in any given period is largely discretionary. In addition, net realized and unrealized investment gains and losses on investments could distort the analysis of trends.

In Third Quarter 2025, we delivered an ROE of 14.0% and a non-GAAP operating ROE of 13.2%, driven by strong investment income, which was 18% higher compared to Third Quarter 2024. ROE improved 1.4 points and non-GAAP operating ROE improved by 1.1 points in Third Quarter 2025 compared to Third Quarter 2024. Our overall combined ratio of 98.6% for Third Quarter 2025 was 0.9 points better than the 99.5% in Third Quarter 2024, driving the higher ROE contribution from our overall insurance operations. Improved underwriting results in the quarter were primarily attributable to lower catastrophe losses, partially offset by unfavorable prior year casualty reserve development of $40 million in Third Quarter 2025 and higher current year loss costs. There was no prior year casualty reserve development in Third Quarter 2024.

In Nine Months 2025, we generated an ROE of 13.0% and a non-GAAP operating ROE of 12.6%, above our 12% target. The improvement from Nine Months 2024 was driven by after-tax underwriting income of $47.3 million this year compared to an underwriting loss of $118 million last year, resulting in a 7.6-point higher ROE. All three insurance segments contributed to the higher ROE. Improved underwriting results in Nine Months 2025 were driven by lower catastrophe losses and lower prior year casualty reserve development, partially offset by higher current year loss costs. Underwriting results for Nine Months 2025 included $90 million of unfavorable prior year casualty reserve development, down from $211 million in Nine Months 2024.

Outlook
The insurance industry continues to face significant uncertainty from the macroeconomic environment, including financial market performance, international trade including the ultimate impact of tariffs, as well as elevated and uncertain loss trends driven by social inflation. Nonetheless, we delivered a 12.6% operating ROE in Nine Months 2025 and remain focused on executing our strategy to manage risk while driving long-term, profitable growth by:

Achieving renewal pure price increases above expected loss trend. We continue to price new and renewal business incorporating our latest view of loss trends and profitability relative to our long-term combined ratio target of 95%. In Nine Months 2025, overall renewal pure pricing across our three insurance segments was 9.9%, up 0.8 points from a year ago.

Deploying granular underwriting refinements. In sectors and jurisdictions where market pricing does not align with our view of rate adequacy, we are taking targeted underwriting actions, including (i) revising underwriting guidelines, (ii) tightening coverage offerings, and (iii) reducing writings.

Seeking to diversify our insurance segments’ mix of business over the long term. Our relatively higher-than-peer casualty premium mix has benefited our results when property lines have been challenged, and our historical catastrophe losses are lower than the industry average. Similarly, the higher-than-peer casualty premium mix may cause the current social inflationary environment to have a proportionately greater impact on our results compared to our peers that have a mix more weighted to property lines.

We believe it is prudent to prioritize improving underwriting margins, which will temper NPW growth in the current environment. NPW grew 4% in Third Quarter 2025 compared to Third Quarter 2024, reflecting our disciplined underwriting and pricing strategy in a competitive market. Policy retention declined modestly as we executed these strategies in a granular fashion. We will maintain a balanced approach and make investments to support future growth. As we position ourselves for the future, we have several strategies to grow market share profitably:

In our existing footprint, we are focused on growing with existing partners and strategically appointing new agency locations. During Nine Months 2025, we had a net increase of 82 agency locations and in full-year 2024, we had a net increase of two hundred agency locations.

Careful and deliberate geographic expansion. Since 2017, we have added fourteen states to our Standard Commercial Lines footprint, including Kansas in Third Quarter 2025. In 2024, our expansion states produced $350 million in premium, which represented approximately 8% of total NPW and approximately 1% marginal total premium growth. We expect to write new business in Montana and Wyoming by the end of 2026.

Technology investments are critical to ensure efficiency and scale. To enhance underwriting scalability, risk management, and claims outcomes, we are actively developing and executing artificial intelligence use cases. We have also made considerable progress modernizing our policy acquisition and claims systems. For example, system enhancements in our E&S Lines segment have created significant operational efficiency, with the segment’s premium production increasing significantly despite limited headcount growth.

After contemplating Nine Months 2025 results, our full-year 2025 guidance are updated as follows:

A GAAP combined ratio between 97% and 98%, including net catastrophe losses of four points and the impact of prior year casualty reserve development reported through Nine Months 2025. Our combined ratio estimate assumes no additional prior year casualty reserve development and no further change in loss cost estimates. We do not make assumptions about future reserve development, as we book our best estimate each quarter;
After-tax net investment income of $420 million, up from prior guidance of $415 million;
An overall effective tax rate of approximately 21.5%; and
Weighted average shares of 61.1 million on a fully diluted basis, reflecting the shares repurchased in Nine Months 2025 and assuming no additional repurchases under our existing share repurchase authorization.

A re-acceleration of severity growth, primarily in accident year 2024 and concentrated within New Jersey, led us to record unfavorable prior year casualty reserve development in Third Quarter 2025 of (i) $35 million in our commercial automobile line of business, and (ii) $5 million in our personal automobile line of business. Nine Months 2025 had unfavorable prior year casualty reserve development of (i) $60 million in our commercial automobile line of business primarily driven by accident years 2022 through 2024, (ii) $10 million in our personal automobile line of business primarily driven by accident year 2024, and (iii) $20 million in our general liability line of business driven by accident years 2022 through 2024. The year-to-date unfavorable prior year casualty reserve development was driven by paid severities that continued to show higher-than-expected emergence.

The unfavorable prior year casualty reserve development in Third Quarter 2024 and Nine Months 2024 was primarily driven by our general liability line of business that experienced increased severities in accident years 2020 through 2023.

Current year loss costs were higher in Third Quarter 2025 and Nine Months 2025 compared to the same prior-year periods, driven by elevated severity trend assumptions attributable to social inflation on our general liability and E&S casualty lines of business, and responding to prior year development in our commercial automobile line of business.

Additional qualitative discussion on prior year casualty reserve development and current year casualty loss costs is included in the insurance segment sections below.

Property Losses
Net catastrophe and non-catastrophe property losses were 10.4 points lower in Third Quarter 2025 and 5.7 points lower in Nine Months 2025 compared to the same prior-year periods. The net catastrophe loss and loss expense ratio was 11.3 points lower in Third Quarter 2025 and 4.9 points lower in Nine Months 2025 compared to the same prior-year periods, as fewer storms impacted our footprint. The non-catastrophe property loss and loss expense ratio was 0.9 points higher in Third Quarter 2025 and 0.8 points lower in Nine Months 2025 compared to the same prior-year periods reflecting (i) the earned impact of higher renewal pure price increases in 2025, (ii) lower claim frequencies, and (iii) normal period-to-period variability of non-catastrophe property losses.

Additional qualitative discussion on non-catastrophe property loss and loss expenses is included in the insurance segment sections below.

Underwriting Expenses
The underwriting expense ratio was flat in Third Quarter 2025 and increased 0.4 points in Nine Months 2025 compared to the same prior-year periods, primarily due to higher profit-based compensation to our distribution partners and employees, reflecting comparatively improved results.

Third Quarter 2025 saw increased unfavorable prior year reserve development and higher current year casualty loss costs. Nine Months 2025 experienced lower unfavorable prior year reserve development, partially offset by higher current year casualty loss costs. The increase in current year casualty loss costs in Third Quarter 2025 and Nine Months 2025 compared to the same prior-year periods was primarily driven by elevated severity trend assumptions attributable to social inflation on our general liability line of business, and responding to prior year development in our commercial automobile line of business.

Refer to the line of business sections below for qualitative discussion on the significant drivers of unfavorable prior year casualty reserve development and current year casualty loss costs.

Property Losses
Net catastrophe and non-catastrophe property losses reduced the loss and loss expense ratio by an aggregate 8.4 points in Third Quarter 2025 and 3.8 points in Nine Months 2025 compared to the same prior-year periods. Net catastrophe losses were 9.9 points lower in Third Quarter 2025 and 4.3 points lower in Nine Months 2025 compared to the same periods last year, driven by lower frequency of wind, winter storm, and hurricane events. Non-catastrophe property losses were 1.5 points higher in Third Quarter 2025 and 0.5 points lower in Nine Months 2025 compared to the same periods last year, driven by the factors described in the "Insurance Operations" section above.

Underwriting Expenses
The underwriting expense ratio increased slightly by 0.1 points in Third Quarter 2025 and 0.5 points Nine Months 2025 compared to the same prior-year periods. The Nine Months 2025 increase was primarily due to higher profit-based compensation to our distribution partners and employees, reflecting comparatively improved results.

We recorded unfavorable prior year casualty reserve development of $20 million in Nine Months 2025, compared to $216 million in Nine Months 2024. We attribute the unfavorable development in both periods to the ongoing, broad-based social inflationary factors impacting this line. Development in Nine Months 2025 was driven by increased severities in accident years 2022 through 2024. Development in Nine Months 2024 was driven by increased severities in accident years 2020 through 2023.

The general liability line of business has experienced a long-term historical trend of meaningful severity increases, partially offset by claim frequency decreases. Prior-year severities developed adversely, which have impacted our view of more recent accident years in 2024 and 2025. We attribute the increased severities to elevated social inflation, which we view as an industry dynamic characterized by higher claimant propensity for attorney representation and litigation, longer settlement times, and higher settlement values. Certain jurisdictions with expanded liability theories and higher damage awards pose increased challenges. We are closely monitoring these jurisdictions and the broader trends across our business.

We experienced an 11.7-point increase in current year casualty loss costs in Third Quarter 2025 and a 8.9-point increase in Nine Months 2025 compared to the same prior-year periods, driven by higher social inflation-related severities primarily in accident years 2022 and 2023 that we observed and responded to throughout 2024. These actions produced full-year 2024 casualty loss costs of 67.0%, compared with 64.6% in Third Quarter 2024 and 64.8% in Nine Months 2024. The 2025 ratio reflects the increased losses recognized in the 2024 accident year.

We believe that social inflation and elevated loss trends continue to support an elevated near-term pricing environment. In response, we have a heightened focus on prudent underwriting and appropriate pricing. Our renewal pure price increase in this line of business was 11.4% in Third Quarter 2025, in line with 11.9% from last quarter and up from 10.6% for the fourth quarter of 2024. In sectors and jurisdictions where market pricing does not align with our view of rate need, we are taking targeted underwriting actions including (i) revising underwriting guidelines, (ii) tightening coverage offerings, and (iii) reducing writings.

We recorded $35 million of unfavorable prior year casualty reserve development in Third Quarter 2025 driven by increased severities in the state of New Jersey for accident year 2024, and $60 million in Nine Months 2025 primarily for increased severities in accident years 2022 through 2024. Current year casualty loss costs were higher in Third Quarter 2025 and Nine Months 2025 compared to the same prior-year periods, driven by the factors described in the "Insurance Operations" section above and by the mix of property and liability coverages within this line of business.

Non-catastrophe property loss and loss expenses decreased 1.2 points in Third Quarter 2025 and 1.6 points in Nine Months 2025 compared to the same prior-year periods, primarily due to (i) the earned impact of higher renewal pure price increases and (ii) period-to-period variability of non-catastrophe property losses.

There was no prior year casualty reserve development in Third Quarter 2025 and Nine Months 2025. The favorable prior year casualty reserve development in Nine Months 2024 was primarily due to lower loss severities in accident years 2021 and prior.

39

The combined ratio was adversely impacted by an increase in current year casualty loss costs of 8.1 points in Third Quarter 2025 and 8.1 points in Nine Months 2025, primarily driven by negative rate changes combined with positive loss trends. These rate level reductions are driven by continued decreases in workers compensation rating bureau loss costs, which form the basis for our filed rating plans, and heavily influence marketplace pricing for this line of business.

NPW decreased 6% in Third Quarter 2025 and 8% in Nine Months 2025 compared to the same prior-year periods, primarily driven by lower direct new business. New business decreased 20% in Third Quarter 2025 and 42% in Nine Months 2025 compared to the same prior-year periods. New policy counts decreased 34% in Third Quarter 2025 and 55% in Nine Months 2025 compared to the same prior-year periods. We have received regulatory approvals for increased rate levels in most of our footprint states and are focused on growth where we believe our rates are adequate.

The change in NPE in Third Quarter 2025 and Nine Months 2025 compared to the same prior-year periods resulted from the same impacts to NPW described above.

Underwriting results for this segment improved in Third Quarter 2025 and Nine Months 2025 compared to the same prior-year periods as we are obtaining positive results from the actions we took to refine our pricing factors and prioritize rate filings to mitigate inflationary impacts. Our more significant rate increases began to take effect early in 2023 and increased in number and magnitude throughout 2024. We expect 2025 rate changes to remain above loss trends but moderate compared to our 2024 rate increases. Through our actions, we achieved renewal pure price increases of 16.9% in Third Quarter 2025 and 19.8% in Nine Months 2025. We are continuing to seek improved homeowners profitability by furthering the use of new policy terms and conditions, including (i) coverage for roofs based on a depreciated value considering the age of the roof rather than full replacement cost and (ii) where allowed by law, mandatory wind/hail deductibles in states exposed to severe convective storms.

Property Losses
Lower net catastrophe and non-catastrophe property losses reduced the loss and loss expense ratio by an aggregate 22.8 points in Third Quarter 2025 and 19.2 points in Nine Months 2025 compared to the same prior-year periods. Net catastrophe losses reflected lower frequency and severity of weather-related catastrophe events this year compared to last year.

Unfavorable prior year casualty reserve development was $5 million in personal automobile in Third Quarter 2025 and $10 million in personal automobile in Nine Months 2025 related to accident year 2024. The development was primarily driven by increased severities related to the New Jersey portfolio. In Nine Months 2024, prior year casualty reserve development reflected (i) $5.0 million of favorable development in our homeowners line, primarily due to lower loss severities in accident years 2021 and prior, offset by (ii) $5.0 million of unfavorable development on our personal automobile line of business, primarily driven by increased loss severities in accident years 2021 through 2023.

Current year casualty loss costs increased 7.2 points in Third Quarter 2025 and 0.8 points in Nine Months 2025 compared to the same prior-year periods, primarily driven by higher loss trend expectations and increased claim severities, which we attribute to the continued impacts of social inflation. Prior-year severities developed adversely over the course of 2024 and impacted our view of the current year loss costs for 2025, resulting in higher current year casualty loss costs this year compared to last.

The loss and loss expense ratio decreased 6.4 points in Third Quarter 2025 and 2.2 points in Nine Months 2025 compared to the same prior-year periods. This decrease was primarily driven by (i) lower catastrophe losses and non-catastrophe property losses due to normal period-to-period variability associated with property losses and (ii) the impact of higher rates per exposure. Partially offsetting the lower property losses were higher current year casualty loss costs, primarily driven by increased severities due to social inflation.

Reinsurance
We successfully completed negotiations of our July 1, 2025 excess of loss treaties that cover Standard Commercial Lines, Standard Personal Lines, and E&S Lines.

We renewed the Casualty Excess of Loss Treaty ("Casualty Treaty") with coverage for $87 million in excess of a $3 million retention per loss occurrence. The first layer was modified with an increase in net retention from $2 million to $3 million, and we continue to retain a portion of the first layer through a 20% co-participation. The 2025 treaty year deposit premium decreased primarily due to the increased retention and co-participation, partially offset by higher projected subject earned premium due to growth in our book of business.

We also renewed the Property Excess of Loss Treaty ("Property Treaty") with the same retention as the expiring treaty, but with a $30 million increase in limit. The treaty now provides coverage for $95 million in excess of a $5 million retention for losses on a per risk basis. The treaty year deposit premium increased modestly, reflecting higher projected subject earned premium due to growth in our book of business and the increased treaty limit.

The following table summarizes the Casualty Treaty and Property Treaty arrangements covering our Insurance Subsidiaries:

Treaty Name Reinsurance Coverage Terrorism Coverage
Casualty Treaty (covers all insurance operations)
There are six layers covering $87 million in excess of $3 million. Losses other than terrorism losses are subject to the following:

- 80% of $3 million in excess of $3 million layer provides 65 reinstatements, $198 million annual aggregate limit;
- 100% of $6 million in excess of $6 million layer provides 14 reinstatements, $90 million annual aggregate limit;
- 100% of $9 million in excess of $12 million layer provides three reinstatements, $36 million annual aggregate limit;
- 100% of $9 million in excess of $21 million layer provides one reinstatement, $18 million annual aggregate limit;
- 100% of $20 million in excess of $30 million layer provides one reinstatement, $40 million annual aggregate limit; and
- 100% of $40 million in excess of $50 million layer provides one reinstatement, $80 million annual aggregate limit.
All NBCR losses are excluded. All other losses stemming from the acts of terrorism are subject to the following:

- 80% of $3 million in excess of $3 million layer with $15 million net annual terrorism aggregate limit;
- 100% of $6 million in excess of $6 million layer with $30 million net annual terrorism aggregate limit;
- 100% of $9 million in excess of $12 million layer with $27 million net annual terrorism aggregate limit;
- 100% of $9 million in excess of $21 million layer with $18 million net annual terrorism aggregate limit;
- 100% of $20 million in excess of $30 million layer with $40 million net annual terrorism aggregate limit; and
- 100% of $40 million in excess of $50 million layer with $80 million net annual terrorism aggregate limit.
Property Treaty (covers all insurance operations)
There are three layers covering 100% of $95 million in excess of $5 million. Losses other than Terrorism Risk Insurance Program Reauthorization Act ("TRIPRA") certified losses are subject to the following reinstatements and annual aggregate limits:

- $5 million in excess of $5 million layer provides 15 reinstatements, $80 million in aggregate limits;
- $20 million in excess of $10 million layer provides four reinstatements, $100 million in aggregate limits; and
- $70 million in excess of $30 million layer provides one reinstatement, $140 million in aggregate limits.
All nuclear, biological, chemical, and radioactive ("NBCR") losses are excluded regardless of whether or not they are certified under the TRIPRA. For non-NBCR losses, the treaty distinguishes between acts committed on behalf of foreign persons or foreign interests ("Foreign Terrorism") and those that are not. The treaty provides annual aggregate limits for Foreign Terrorism (other than NBCR) acts of $15 million for the first layer, $60 million for the second layer, and $70 million for the third layer. Non-Foreign Terrorism losses (other than NBCR) are covered to the same extent as non-terrorism losses.


Investments
Our Investments segment's objectives are to maximize the economic value of our investment portfolio by achieving stable, risk-adjusted after-tax net investment income and generate long-term growth in book value per share, considering prevailing market conditions, our enterprise risk tolerances, and other risk implications. We aim to accomplish this by:

Maximizing the portfolio's overall total return by investing (i) the premiums from our insurance operations, (ii) amounts generated through our capital management strategies, including debt and equity security issuances, and (iii) profits of our business, and

Maintaining (i) a well-diversified portfolio across issuers, sectors, and asset classes and (ii) a high credit quality fixed income securities portfolio with a duration and maturity profile at an acceptable risk level that provides ample liquidity.

43

The effective duration of our fixed income and short-term investments was 4.1 years as of September 30, 2025. We monitor and manage the effective duration to maximize yield while managing interest rate risk at an acceptable level. We buy and sell investments with the intent of maximizing investment returns in the current market environment, while balancing capital preservation and ensuring adequate liquidity to support our insurance business.

Our fixed income and short-term investments represented 92% of invested assets at September 30, 2025 and December 31, 2024. These investments had (i) a weighted average credit rating of "A+" as of both September 30, 2025 and December 31, 2024, and (ii) investment grade holdings representing 97% of the total fixed income and short-term investment portfolio at both September 30, 2025 and December 31, 2024.

For further details on the composition, credit quality, and various risks to which our portfolio is subject, see Item 7A. "Quantitative and Qualitative Disclosures About Market Risk." of our 2024 Annual Report.

On July 4, 2025, the One Big Beautiful Bill Act (the "Act") became law. The legislation is extensive, and some changes will affect current and future years. The tax law changes are reflected in the enactment period, which is Third Quarter 2025. Accordingly, we have analyzed the Act's major impacts, which include provisions that allow 100% bonus depreciation for certain qualified assets and full deduction of domestic research and development expenditures. Both are temporary differences and do not impact total tax expense but provide a cash tax benefit that is estimated at $6.4 million, for the 2025 tax year.

Liquidity and Capital Resources
Capital resources and liquidity reflect our ability to generate cash flows from business operations, borrow funds at competitive rates, and raise new capital to meet our operating and growth needs.

Liquidity
We manage liquidity by generating sufficient cash flows to meet our business operations' short-term and long-term cash requirements. We adjust our liquidity requirements based on economic conditions, market conditions, and future cash flow commitments, as discussed further below.

Sources of Liquidity
The Parent's sources of cash historically have consisted of dividends from the Insurance Subsidiaries, the Parent's investment portfolio, borrowings under third-party lines of credit, intercompany revolving demand loan agreements with certain Insurance Subsidiaries, and the issuance of equity (common or preferred) and debt securities. We continue to monitor these sources, considering our short-term and long-term liquidity and capital preservation strategies.

45

The Parent's cash and components of its investment portfolio were as follows:

($ in thousands) September 30, 2025 December 31, 2024
Fixed income securities
$ 288,880 268,486
Equity securities

Alternative investments
21,137 18,443
Cash
58 91
Total investments and cash
$ 478,251 402,491

Short-term investments have historically been maintained in "AAA" rated money market funds and fixed income securities are comprised of high-quality, liquid government and corporate securities.

The amount and composition of the Parent's investment portfolio may change over time based on various factors, including the amount and availability of dividends from our Insurance Subsidiaries, investment income, expenses, other Parent cash needs, such as dividends payable to stockholders, asset allocation investment decisions, inorganic growth opportunities, debt retirement, and share repurchases. Our target is for the Parent to maintain liquid investments of at least twice its expected annual net cash outflow needs.

Insurance Subsidiary Dividends
The Insurance Subsidiaries generate liquidity through insurance float, created by collecting premiums and earning investment income before paying claims. Given the long payment patterns of certain claims, the float period can extend over many years. Our investment portfolio consists of securities with maturity dates that continually provide a source of cash flow for claims payments in the ordinary course of business. To protect our Insurance Subsidiaries' capital, we purchase reinsurance coverage for significantly large claims or catastrophes that may occur.

Our Insurance Subsidiaries may pay dividends to the Parent company. The Insurance Subsidiaries did not declare or pay cash dividends to the Parent in Nine Months 2025. As of December 31, 2024, our allowable ordinary maximum dividend is $290 million for 2025. All Insurance Subsidiary dividends to the Parent are (i) subject to the approval and/or review of its domiciliary state insurance regulator and (ii) generally payable only from earned statutory surplus reported in its annual statements as of the preceding December 31. Although domiciliary state insurance regulators have historically approved dividends, there is no assurance they will approve future Insurance Subsidiary dividends.

New Jersey corporate law also limits the maximum amount of dividends the Parent can pay our stockholders if either (i) the Parent would be unable to pay its debts as they become due in the usual course of business or (ii) the Parent’s total assets would be less than its total liabilities. The Parent’s ability to pay dividends to stockholders is also impacted by (i) covenants in its credit agreement that obligate it, among other things, to maintain a minimum consolidated net worth and a maximum ratio of consolidated debt to total capitalization and (ii) the terms of our preferred stock that prohibit dividends from being declared or paid on our common stock if dividends are not declared and paid, or made payable, on all outstanding preferred stock for the latest completed dividend period.

For additional information regarding dividend restrictions and financial covenants, where applicable, see Note 11. "Indebtedness," Note 17. "Equity," and Note 22. "Statutory Financial Information, Capital Requirements, and Restrictions on Dividends and Transfers of Funds" in Item 8. "Financial Statements and Supplementary Data." of our 2024 Annual Report.

Line of Credit
On June 30, 2025, the Parent entered into a Credit Agreement with the lenders named therein (the "Lenders") and Wells Fargo Bank, National Association, as administrative agent ("Line of Credit"). Under the Line of Credit, the Lenders have agreed to provide the Parent with a $100 million revolving credit facility that can be increased to $200 million with the Lenders' consent. The Line of Credit will mature on June 30, 2028, and has a variable interest rate based on the Parent’s debt ratings. This agreement replaced a prior credit agreement that the Parent terminated in conjunction with entering into the Line of Credit. No borrowings were made under either credit facility in Nine Months 2025. For additional information regarding the Line of Credit and corresponding representations, warranties, and covenants, see Note 12. "Indebtedness" in Item 1. "Financial Statements" of this Form 10-Q.

46

Four Insurance Subsidiaries are members of Federal Home Loan Bank ("FHLB") branches, as shown in the following table. Membership requires the ownership of branch stock and includes the right to access liquidity. All Federal Home Loan Bank of Indianapolis ("FHLBI") and Federal Home Loan Bank of New York ("FHLBNY") borrowings are required to be secured by investments pledged as collateral. For additional information regarding collateral outstanding, refer to Note 4. "Investments" in Item 1. "Financial Statements." of this Form 10-Q.

Branch Insurance Subsidiary Member
FHLBI
Selective Insurance Company of South Carolina 1
Selective Insurance Company of the Southeast 1
FHLBNY
Selective Insurance Company of America
Selective Insurance Company of New York ("SICNY")
1 These subsidiaries are jointly referred to as the "Indiana Subsidiaries" because they are domiciled in Indiana.

The Line of Credit permits aggregate borrowings from the FHLBI and the FHLBNY up to 10% of the respective member company’s admitted assets for the previous year. SICNY is domiciled in New York, which limits its FHLBNY borrowings to the lesser of 5% of admitted assets for the most recently completed fiscal quarter or 10% of the previous year-end's admitted assets. As of September 30, 2025, we had remaining capacity of $611.2 million for FHLB borrowings, with a $25.0 million additional stock purchase requirement to allow the member companies to borrow their remaining capacity amounts.

Short-term Borrowings
We made no material short-term borrowings from FHLB branches during Nine Months 2025.

Intercompany Loan Agreements
The Parent has lending agreements with the Indiana Subsidiaries, approved by the Indiana Department of Insurance, that provide the Parent with additional intercompany liquidity. Like the Line of Credit, these lending agreements limit the Parent’s borrowings from the Indiana Subsidiaries to 10% of the admitted assets of the respective Indiana Subsidiary. The outstanding balance on these intercompany loans was $35.0 million as of both September 30, 2025 and December 31, 2024. The remaining capacity under these intercompany loan agreements was $171.8 million as of both September 30, 2025 and December 31, 2024. We have other insurance regulator-approved intercompany agreements that facilitate liquidity management between the Parent and the Insurance Subsidiaries to enhance flexibility.

Capital Market Activities
In Nine Months 2025, the Parent issued $400 million of 5.90% Senior Notes due 2035, resulting in net proceeds of $395.9 million after a $0.1 million discount and debt issuance costs of approximately $4.1 million. The proceeds from this debt issuance are being used for general corporate purposes, including supporting organic growth with a $200 million capital contribution to the Insurance Subsidiaries in March 2025. The Parent had no private or public stock issuances during Nine Months 2025.

During Nine Months 2025, we repurchased 698,312 shares of our common stock under our existing share repurchase program for $55.6 million, a $79.60 average price per share, excluding commissions paid and estimated excise tax. We had $19.9 million of remaining capacity under our share repurchase program as of September 30, 2025. For additional information on this share repurchase program, refer to Note 17. "Equity" in Item 8. "Financial Statements and Supplementary Data." of our 2024 Annual Report. On October 22, 2025, the Company announced that its Board of Directors authorized a new share repurchase program under which the Company may repurchase issued and outstanding shares of common stock up to $200 million, exclusive of any excise tax impact. This program is effective on October 27, 2025 and has no expiration date. The Company’s existing share repurchase program remained effective through October 24, 2025.

Uses of Liquidity
The Parent uses the liquidity generated from the sources discussed above to pay dividends to our stockholders, among other things. Dividends on shares of the Parent's common and preferred stock are declared and paid at the discretion of the Board of Directors ("Board") based on our operating results, financial condition, capital requirements, contractual restrictions, and other relevant factors. Our Board declared:

A 13% increase in the quarterly cash dividend on common stock, to $0.43 per common share, that is payable December 1, 2025, to holders of record on November 14, 2025; and
•    A quarterly cash dividend of $287.50 per share on our 4.60% Non-Cumulative Preferred Stock, Series B (equivalent to $0.28750 per depositary share) payable on December 15, 2025, to holders of record as of December 1, 2025.

47

Our ability to meet our interest and principal repayment obligations on our debt and our ability to continue to pay dividends to our stockholders is dependent on (i) liquidity at the Parent, (ii) the ability of the Insurance Subsidiaries to pay dividends, if necessary, and/or (iii) the availability of other sources of liquidity to the Parent. Our next borrowing principal repayment is $60 million to FHLBI due on December 16, 2026.

Restrictions on the ability of the Insurance Subsidiaries to declare and pay dividends without alternative liquidity options could materially affect our ability to service debt and pay dividends on common and preferred stock.

Capital Resources
Capital resources ensure we can pay policyholder claims, furnish the financial strength to support the business of underwriting insurance risks, and facilitate continued business growth. At September 30, 2025, we had GAAP stockholders' equity of $3.5 billion and statutory surplus of $3.4 billion. With total debt of $902.3 million at September 30, 2025, our debt-to-capital ratio was 20.5%. For additional information on our statutory surplus, see Note 22. "Statutory Financial Information, Capital Requirements, and Restrictions on Dividends and Transfers of Funds" in Item 8. "Financial Statements and Supplementary Data." of our 2024 Annual Report.

The following table summarizes certain contractual obligations we had at September 30, 2025, that may require us to invest additional amounts into our investment portfolio, which we would fund primarily with operating cash flows.

($ in millions) Amount of Obligation
Alternative and other investments $ 346.1
Non-publicly traded collateralized loan obligations in our fixed income securities portfolio 253.0
Non-publicly traded common stock within our equity portfolio 19.2
CMLs 23.3
Privately-placed corporate securities 97.6
Total $ 739.2

There is no certainty (i) these additional investments will be required or (ii) about the timing of funding. We expect to have the capacity to fund these commitments through our normal operating and investing activities as they come due.

The following table provides future cash payments on our notes payable as of September 30, 2025, including our 5.9% Senior Notes, details about which are included in the "Capital Markets" discussion above and Note 12. "Indebtedness" in Item 1. "Financial Statements." of this Form 10-Q:

Our current and long-term material cash requirements associated with (i) loss and loss expense reserves and (ii) contractual obligations under operating and financing leases for office space and equipment have not materially changed since December 31, 2024. The Insurance Subsidiaries' net loss and loss expense reserves duration was 3.0 years at December 31, 2024.

Our other cash requirements include, without limitation, dividends to stockholders, capital expenditures, and other operating expenses, including commissions to our distribution partners, labor costs, premium taxes, general and administrative expenses, and income taxes.

As of September 30, 2025 and December 31, 2024, we had no (i) material guarantees on behalf of others and trading activities involving non-exchange traded contracts accounted for at fair value, (ii) material transactions with related parties other than those disclosed in Note 18. "Related Party Transactions" in Item 8. "Financial Statements and Supplementary Data." of our 2024 Annual Report, and (iii) material relationships with unconsolidated entities or financial partnerships, such as structured finance or special purpose entities, established to facilitate off-balance sheet arrangements or other contractually narrow or limited purposes. Consequently, we are not exposed to any material financing, liquidity, market, or credit risk related to off-balance sheet arrangements.

48

We continually monitor our cash requirements and the capital resources we maintain at the holding company and Insurance Subsidiary levels. As part of our long-term capital strategy, we strive to maintain capital metrics that support our targeted financial strength relative to the macroeconomic environment. Based on our analysis and market conditions, we may take a variety of actions, including, without limitation, contributing capital to the Insurance Subsidiaries, issuing additional debt and/or equity securities, repurchasing existing debt, repurchasing shares of the Parent’s common stock, and adjusting common stockholders’ dividends.

Our capital management strategy is intended to protect the interests of the policyholders of the Insurance Subsidiaries and our stockholders and enhance our financial strength and underwriting capacity. We have a solid capital base and high-quality underwriting portfolio, positioning us well to leverage potential market opportunities.

Book value per common share increased 13% to $54.46 as of September 30, 2025, from $47.99 as of December 31, 2024, primarily driven by $4.97 in net income (loss) available to common stockholders per diluted common share and a $2.77 decrease in after-tax net unrealized losses on our fixed income securities portfolio, partially offset by $1.14 in dividends to our common stockholders. A decline in benchmark U.S. Treasury rates primarily drove the decrease in net unrealized losses on our fixed income securities. Our adjusted book value per share, which is book value per share excluding total after-tax unrealized gains or losses on investments included in accumulated other comprehensive income (loss), increased to $55.83 as of September 30, 2025, from $52.10 as of December 31, 2024.

Cash Flows
Net cash provided by operating activities increased to $856.8 million in Nine Months 2025, compared to $767.7 million in Nine Months 2024, primarily driven by higher levels of cash received for premiums. For more information on our underwriting results, refer to "Insurance Operations" above in this MD&A.

Net cash used in investing activities increased to $1,158.1 million in Nine Months 2025, compared to $687.3 million in Nine Months 2024, primarily due to the investment of proceeds from our 5.9% Senior Note issuance in Six Months 2025. These proceeds also drove the $262.4 million in net cash provided by financing activities in Nine Months 2025, compared to $81.0 million in net cash used in financing activities in Nine Months 2024. Partially offsetting cash proceeds from the 5.9% Senior Notes issuance was cash used for share repurchases and common stock dividends.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

There have been no material changes in the information about market risk set forth in our 2024 Annual Report.

49

ITEM 4. CONTROLS AND PROCEDURES.

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act")), as of the end of the period covered by this report. In performing this evaluation, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control Integrated Framework ("COSO Framework") in 2013. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures as of the end of such period are (i) effective in recording, processing, summarizing, and reporting information on a timely basis that we are required to disclose in the reports that we file or submit under the Exchange Act, and (ii) effective in ensuring that information that we are required to disclose in the reports that we file or submit under the Exchange Act is appropriately accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions about required disclosure. No changes in our internal control over financial reporting (as such term is defined in Rule 13a-15(f) of the Exchange Act) occurred during Third Quarter 2025 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS.

Incidental to our insurance operations, we are routinely engaged in legal proceedings with inherently unpredictable outcomes that could have a material adverse effect on our consolidated results of operations or cash flows in particular quarterly or annual periods. For additional information regarding our legal risks, refer to Note 16. "Litigation" in Item 1. "Financial Statements." of this Form 10-Q and Item 1A. "Risk Factors." below in Part II. "Other Information." As of September 30, 2025, we have no material pending legal proceedings that could have a material adverse effect on our consolidated financial condition, results of operations, or cash flows.

ITEM 1A. RISK FACTORS.

Certain risk factors can significantly impact our business, liquidity, capital resources, results of operations, financial condition, and debt ratings. These risk factors might affect, alter, or change our actions in executing our long-term capital strategy. Examples include, without limitation, contributing capital to any or all of the Insurance Subsidiaries, issuing additional debt and/or equity securities, repurchasing our existing debt and/or equity securities, or increasing or decreasing common stockholders' dividends. We operate in a continually changing business environment, and new risk factors that we cannot predict or assess may emerge at any time. Consequently, we can neither predict such new risk factors nor assess the potential future impact on our business. Except as discussed below, there have been no material changes from the risk factors disclosed in Item 1A. "Risk Factors." in our 2024 Annual Report.

Changes in international trade policy could adversely and materially affect our business, results of operations, financial condition, and growth.
Changes in international trade policies and tariffs by the United States and other countries, particularly large trading partners like Canada, China, and Mexico, could (i) impact our claims severity across multiple lines of business and cause adverse reserve development by increasing costs for materials and parts used in claims involving real property and personal property, including commercial and personal automobiles and (ii) negatively affect our investments' fair value and/or our level of investment income.

Risks Associated with the Shutdown of the United States Government
The United States federal government has been shut down since October 1, 2025. When the government is not funded, non-essential federal employees are furloughed and services are limited or curtailed. A prolonged shutdown may lead to broader economic uncertainty and financial market volatility. These conditions could negatively affect our investment portfolio, policyholder behavior, and overall demand for property and casualty insurance products. Disruptions to federal disaster response or recovery programs, including the National Flood Insurance Program (“NFIP”), could impact funding for and our ability to pay NFIP claims in the event of significant natural disasters, potentially impacting our reputation.

While we strive to mitigate these risks through contingency planning and industry government affairs efforts, the ultimate impact of any government shutdown is difficult to predict and may be outside our control. Any material adverse effects resulting from a government shutdown could have a negative impact on our business, financial position, and results of operations.
