Branchville, NJ - October 22, 2025 - Selective Insurance Group, Inc. (NASDAQ: SIGI) reported financial results for the third quarter ended September 30, 2025, with net income per diluted common share of $1.85 and non-GAAP operating income1 per diluted common share of $1.75. ROE was 14.0% and non-GAAP operating ROE1 was 13.2%.

For the quarter, Selective's combined ratio was 98.6%. Catastrophe losses were 2.1 points, and net unfavorable prior year casualty reserve development was 3.3 points, driven by $40 million of reserve strengthening, mainly in standard commercial lines. NPW grew 4% from a year ago driven by renewal pure price increases of 9.6%. Net investment income increased 18% from a year ago, to $110 million after-tax, and generated 13.6 points of annualized ROE in the quarter.

Today, the company announces that its Board of Directors authorized a new share repurchase program under which it may repurchase up to $200 million of its outstanding shares. The program is effective October 27, 2025 and has no expiration date. The company’s existing share repurchase program, which had $19.9 million of shares remaining as of September 30, 2025, will remain effective through October 24, 2025.

“Our full-year combined ratio outlook remains at 97 to 98%. With a 98.3% combined ratio through the first nine months of the year and strong net investment income, we delivered year-to-date operating ROE of 12.6%,” said John J. Marchioni, Chairman, President and Chief Executive Officer.

“We believe our focus on improving underwriting margins and investing in areas that support long-term, profitable growth positions us for stronger, more sustainable performance. This quarter, we expanded our Standard Commercial Lines footprint into Kansas, and we plan to enter Montana and Wyoming in 2026. We’ve strategically added 14 states over the last 8 years, significantly growing our market and advancing our stated goal of operating our Standard Commercial Lines business with a near-national footprint.”

“We remain committed to our long-term capital management strategy – prioritizing investments in insurance operations that drive profitable growth, targeting 20% to 25% of our earnings returned through dividends over time, and opportunistically repurchasing shares. This quarter, we are pleased to announce a 13% increase in our quarterly dividend – our twelfth consecutive annual increase – and a new $200 million share repurchase program authorization, replacing the prior program. We repurchased $36 million of common stock in the quarter under our prior authorization. Together, these actions underscore our unwavering commitment to delivering long-term value to shareholders,” concluded Mr. Marchioni.

Overall Insurance Operations

For the third quarter, overall NPW increased 4%, as we focused on rate and non-rate actions to improve underwriting profitability. Average renewal pure price increased 9.6%, down 0.9 points from a year ago. Our 98.6% combined ratio was 0.9 points better than a year ago, driven by lower catastrophe losses. This was partially offset by 3.3 points, or $40 million, of unfavorable prior year casualty reserve development and higher current year casualty loss costs.

Overall, insurance segment performance generated 1.6 points of ROE in the third quarter of 2025.

Standard Commercial Lines Segment

For the third quarter, Standard Commercial Lines premiums (representing 78% of total NPW) grew 4% from a year ago. The premium growth reflected average renewal pure price increases of 8.9% and retention of 82%. The third quarter combined ratio was 101.1%, up 1.9 points from a year ago. Unfavorable prior year casualty reserve development and higher current year casualty loss costs in Commercial Auto drove the change. This was partially offset by lower net catastrophe losses.

Standard Personal Lines Segment

For the third quarter, our deliberate profit improvement actions caused Standard Personal Lines premiums (representing 9% of total NPW) to decline 6% from a year ago and new business to fall 20%. We continue to focus on growth in states where we have filed and obtained adequate rate approvals. Renewal pure price was 16.9% and retention was 79%. The third quarter 2025 combined ratio improved 12.0 points from a year ago to 110.1%, due to lower catastrophe losses. This was partially offset by higher current year casualty loss costs and unfavorable prior year casualty reserve development in Personal Auto.

Excess and Surplus Lines Segment

For the third quarter, Excess and Surplus Lines premiums (representing 13% of total NPW) increased 14% from the prior-year period, driven by average renewal pure price increases of 8.3%. The third quarter 2025 combined ratio was 76.2%, 7.0 points better than a year ago driven by lower catastrophe losses and non-catastrophe property losses. This was partially offset by higher current year casualty loss costs.

Book value per common share increased by $6.47, or 13%, during the first nine months of 2025. The increase was primarily attributable to $4.97 of net income per diluted common share and a $2.77 decrease in after-tax net unrealized losses on our
4


fixed income securities portfolio, partially offset by $1.14 in common stockholder dividends. The decrease in after-tax net unrealized losses on our fixed income securities portfolio was primarily driven by lower interest rates. In the third quarter of 2025, the Company repurchased 464,701 shares of common stock at an average price of $77.95 for $36.2 million.

Selective's Board of Directors also declared:

•    A quarterly cash dividend on common stock of $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.

Guidance
For 2025, our full-year expectations are updated as follows:

•A GAAP combined ratio of 97% to 98%, including net catastrophe losses of 4 points and the impact of prior year casualty reserve development reported through the third quarter. 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 21.5%; and
•Weighted average shares of 61.1 million on a fully diluted basis, reflecting the shares repurchased in the first nine months of 2025 and assuming no additional repurchases under our share repurchase authorization.

The supplemental investor package, with financial information not included in this press release, is available on the Investors page of Selective’s website at www.Selective.com.

1Reconciliation of Net Income (Loss) Available to Common Stockholders to Non-GAAP Operating Income (Loss) and Certain Other Non-GAAP Measures
Non-GAAP operating income (loss), non-GAAP operating income (loss) per diluted common share, and non-GAAP operating return on common equity differ from net income (loss) available to common stockholders, net income (loss) available to common stockholders per diluted common share, and return on common equity, respectively, by the exclusion of after-tax net realized and unrealized gains and losses on investments included in net income (loss). Adjusted book value per common share differs from book value per common share by excluding total after-tax unrealized gains and losses on investments included in accumulated other comprehensive income (loss). These non-GAAP measures are used as important financial measures by management, 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 gains and losses on investments could distort the analysis of trends. These operating measurements are not intended to be a substitute for net income (loss) available to common stockholders, net income (loss) available to common stockholders per diluted common share, return on common equity, and book value per common share prepared in accordance with U.S. generally accepted accounting principles (GAAP). Reconciliations of net income (loss) available to common stockholders, net income (loss) available to common stockholders per diluted common share, return on common equity, and book value per common share to non-GAAP operating income (loss), non-GAAP operating income (loss) per diluted common share, non-GAAP operating return on common equity, and adjusted book value per common share, respectively, are provided in the tables below.

Note: All amounts included in this release exclude intercompany transactions.

Certain statements in this report, 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 and 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. In some cases, forward-looking statements include the words “may,” “will,” “could,” “would,” “should,” “expect,” “plan,” “anticipate,” “attribute,” “confident,” “strong,” “target,” “project,” “intend,” “believe,” “estimate,” “predict,” “potential,” “pro forma,” “seek,” “likely,” “continue,” or comparable terms. 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.

Factors that could cause our actual results to differ materially from what we project, forecast, or estimate in forward-looking statements include, without limitation:
•Challenging conditions in the economy, global capital markets, the banking sector, and commercial real estate, including prolonged higher inflation, could increase loss costs and negatively impact investment portfolios;
•Deterioration in the public debt, public equity, or private investment markets that could lead to investment losses and interest rate fluctuations;
•Ratings downgrades on individual securities we own could negatively affect investment values, impacting statutory surplus;
•The development and adequacy of our loss reserves and loss expense reserves;
•Frequency and severity of catastrophic events, including natural events that climate change may impact, such as hurricanes, severe convective storms, tornadoes, windstorms, earthquakes, hail, severe winter weather, floods, and fires, and man-made events such as criminal and terrorist acts, including cyber-attacks, explosions, and civil unrest;
•Adverse market, governmental, regulatory, legal, political, or judicial rulings, conditions or actions, including the impact of social inflation and the impact of a continued shutdown of the U.S. government;
•The significant geographic concentration of our business in the eastern portion of the United States;
•The cost, terms and conditions, and availability of reinsurance;
•Our ability to collect on reinsurance and the solvency of our reinsurers;
•The impact of changes in U.S. trade policies and imposition of tariffs on imports that may lead to higher than anticipated inflationary trends for our loss and loss expenses;
•Ongoing wars and conflicts impacting global economic, banking, commodity, and financial markets, exacerbating ongoing economic challenges, including inflation and supply chain disruption, all of which can influence insurance loss costs, premiums, and investment valuations;
•Uncertainties related to insurance premium rate increases and business retention;
•Changes in insurance regulations that impact our ability to write and/or cease writing insurance policies in one or more states;
•The effects of data privacy or cyber security laws and regulations on our operations;
•Major defect or failure in our internal controls or information technology and application systems that result in marketplace brand damage, increased senior executive focus on crisis and reputational management issues, and/or increased expenses, particularly if we experience a significant privacy breach;
•Potential tax or federal financial regulatory reform provisions that could pose certain risks to our operations;
•Our ability to maintain favorable financial ratings, which may include sustainability considerations, from rating agencies, including AM Best, Standard & Poor’s, Moody’s, and Fitch;
•Our entry into new markets and businesses; and
•Other risks and uncertainties we identify in filings with the United States Securities and Exchange Commission, including our Annual Report on Form 10-K and other periodic reports.

Non-GAAP operating income (loss), non-GAAP operating income (loss) per diluted common share, and non-GAAP operating return on common equity are measures comparable to net income (loss) available to common stockholders, net income (loss) available to common stockholders per diluted common share, and return on common equity, respectively, but excludes after-tax net realized and unrealized gains and losses on investments included in net income (loss). Adjusted book value per common share is a measure 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 used as important financial measures by management, 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 gains and losses on investments could distort the analysis of trends. These operating measurements are not intended as a substitute for net income (loss) available to common stockholders, net income (loss) available to common stockholders per diluted common share, return on common equity, and book value per common share prepared in accordance with U.S. generally accepted accounting principles (GAAP). Reconciliations of net income (loss) available to common stockholders, net income (loss) available to common stockholders per diluted common share, return on common equity, and book value per common share to non-GAAP operating income (loss), non-GAAP operating income (loss) per diluted common share, non-GAAP operating return on common equity, and adjusted book value per common share, respectively, are provided in the tables above.

INVESTOR PRESENTATION Third Quarter 2025 Copyright © 2025 by Selective Insurance Group, Inc. All rights reserved. Exhibit 99.3

 
SAFE HARBOR STATEMENT We make certain statements and reference other information in this presentation that are “forward-looking statements” as 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 and 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. We discuss factors that could cause our actual results to differ materially from those we project, forecast, or estimate in forward-looking statements in further detail in Selective’s public filings with the United States Securities and Exchange Commission. We undertake no obligation to publicly update or revise any forward-looking statements – whether as a result of new information, future events or otherwise – other than as the federal securities laws may require. This presentation also includes certain non-GAAP financial measures within the meaning of Regulation G, including “non-GAAP operating earnings per share,” “non-GAAP operating income,” “non-GAAP operating return on equity,” and “adjusted book value per share.” Definitions of these non-GAAP measures and a reconciliation to the most comparable GAAP figures are available in our Annual Report on Form 10-K and our Supplemental Investor Package, both found on our website www.selective.com under “Investors/Reports & Earnings.” Our commentary references non-GAAP measures we and the investment community use to make it easier to evaluate our insurance business. These non-GAAP measures, however, may not be comparable to similarly titled measures used outside of the insurance industry. Investors are cautioned not to unduly rely on these non-GAAP measures in assessing our overall financial performance. 2
