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.

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.

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.

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.

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.

For the third quarter, after-tax net investment income of $110 million was up 18% from a year ago. The after-tax income yield averaged 4.1% for both the fixed income securities portfolio and the overall portfolio. With invested assets per dollar of common stockholders' equity of $3.36 as of September 30, 2025, net investment income generated 13.6 points of annualized ROE.

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 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.

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.

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.
