Branchville, NJ - January 29, 2026 - Selective Insurance Group, Inc. (NASDAQ: SIGI) reported financial results for the fourth quarter ended December 31, 2025, with net income per diluted common share of $2.52 and non-GAAP operating income1 per diluted common share of $2.57. ROE was 18.3% and non-GAAP operating ROE1 was 18.7%.

For the quarter, Selective's combined ratio was 93.8%. Catastrophe losses were 1.7 points, and there was no net prior year casualty reserve development. NPW grew 4% from a year ago, driven by renewal pure price increases of 8.3%. Net investment income increased 17% from a year ago, to $114 million after-tax, generating 13.6 points of annualized ROE in the quarter.

For the year, Selective reported net income per diluted common share of $7.49 and non-GAAP operating income1 per diluted common share of $7.38. The 2025 combined ratio was 97.2%, an improvement of almost six points, driven by the loss and loss expense ratio. NPW increased 5% driven by renewal pure price increases of 9.5%. After-tax net investment income was $421.2 million, up 16% from a year ago, and generated 13.3 points of ROE.

“We are well-positioned to build on recent momentum. We delivered a double-digit operating ROE of 14.2% in 2025, reflecting the strength of our disciplined execution and resilience of our business model. This exceeds our ten-year average operating ROE of 12.1%. Our performance drove an 18% increase in book value per share in 2025, and we returned $182 million to common stockholders through regular dividends and opportunistic share repurchases,” said John J. Marchioni, Chairman, President and Chief Executive Officer.

“We executed key strategic initiatives across our business, delivering excellent growth and underwriting profitability in Excess and Surplus Lines. In Personal Lines, we improved our underwriting results as we continue to shift toward the mass affluent market. We also are executing targeted rate and underwriting actions in Standard Commercial Lines to achieve future profitability improvements.”

“As Selective celebrates its 100th anniversary in 2026, we are building on a century of strength and resilience while maintaining a clear focus on the future. Our efforts include advancing strategic priorities that enhance our operational fundamentals in risk selection, individual policy pricing, and claims outcomes; diversifying revenue and income within and across our three insurance segments; and expanding our use of data analytics and technology, including artificial intelligence, to enhance efficiency and performance. We remain committed to making strategic investments that fuel continued growth, innovation, and performance excellence,” concluded Mr. Marchioni.

In the fourth quarter, overall NPW increased 4%, as we implemented rate and non-rate actions to enhance underwriting profitability. Average renewal pure price increased 8.3%, down 2.4 points from a year ago. Our combined ratio improved to 93.8%, 4.7 points better than a year ago, primarily because of the lack of prior year casualty reserve development compared to 8.8 points of unfavorable prior year casualty reserve development a year ago. This was partially offset by higher current year casualty loss costs.

Overall, insurance segment performance generated 7.2 points of ROE in the fourth quarter of 2025, up 5.4 points from the fourth quarter of 2024.

In the fourth quarter, Standard Commercial Lines premiums, which account for 78% of total NPW, grew 5% from a year ago. This growth reflected average renewal pure price increases of 7.5% and retention of 82%. The fourth quarter combined ratio was 92.9%, 7.3 points better than a year ago. The improvement was driven by favorable prior year casualty reserve development of 1.6 points, compared to unfavorable prior year casualty reserve development of 8.5 points a year ago. This was partially offset by higher current year casualty loss costs in Commercial Auto.

We continue to focus on growth in states where we have filed and obtained adequate rate approvals. For the fourth quarter, our deliberate profit improvement actions resulted in Standard Personal Lines premiums, which represent 8% of total NPW, declining 8% and new business falling 18% from a year ago. Renewal pure price was 15.1% and retention was 80%. The fourth quarter 2025 combined ratio increased 11.3 points from a year ago to 103.0%, primarily due to higher current year casualty loss costs driven by Personal Auto and catastrophe losses.

For the fourth quarter, Excess and Surplus Lines premiums, which represent 14% of total NPW, increased 4% from the prior-year period, driven by average renewal pure price increases of 7.8%. The fourth quarter 2025 combined ratio was 93.1%, in line with a year ago.

For the fourth quarter, after-tax net investment income was $114 million, up 17% 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 $3.32 as of December 31, 2025, net investment income generated 13.6 points of annualized ROE.

Book value per common share increased by $8.75, or 18%, during 2025. The increase was primarily attributable to $7.49 of net income per diluted common share and a $3.01 decrease in after-tax net unrealized losses on our fixed income securities portfolio, partially offset by $1.57 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 fourth quarter of 2025, the Company repurchased $30 million, or 395,073 shares, of common stock at an average price of $75.94.

Selective's Board of Directors also declared:

•    A quarterly cash dividend on common stock of $0.43 per common share payable on March 2, 2026, to holders of record as of February 13, 2026; 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 March 16, 2026, to holders of record as of February 27, 2026.

For 2026, our full-year expectations are as follows:

•A GAAP combined ratio of 96.5% to 97.5%, including net catastrophe losses of 6 points. Our combined ratio estimate assumes no prior year casualty reserve development, as we book our best estimate each quarter. We do not make assumptions about future reserve development;

•After-tax net investment income of $465 million;

•An overall effective tax rate of 21.5%; and

•Weighted average shares of 61 million on a fully diluted basis.

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 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.
