BRANCHVILLE, N.J.--(BUSINESS WIRE)--Selective Insurance Group, Inc. (NASDAQ: SIGI) reported financial results for the second quarter ended June 30, 2026, with net income per diluted common share of $2.11 and non-GAAP operating income¹ per diluted common share of $1.95. ROE was 14.8% and non-GAAP operating ROE¹ was 13.7%.

For the quarter, Selective's combined ratio was 98.0%. Catastrophe losses were 5.6 points, and there was no net prior year casualty reserve development. NPW decreased 5% from a year ago driven by a 6% decrease in Standard Commercial Lines. Renewal pure price increases were 6.5%. Net investment income increased 18% from a year ago, to $119 million after-tax, generating 13.9 points of annualized ROE in the quarter.

“Our results reflect disciplined execution in an increasingly competitive environment. Operating ROE in the quarter was 13.7%, which marked our eighth consecutive quarter of double-digit operating returns. With our strong capital position and commitment to delivering long-term value, we returned 45% of after-tax net income through our regular dividend and $32 million of share repurchases. Even with this capital return, book value per share grew 3% in the quarter,” said John J. Marchioni, Chairman, President and Chief Executive Officer.

“Over the last two years, we have taken deliberate actions to improve the quality and long-term profitability of our underwriting portfolio. While those decisions contributed to lower premium in the quarter, they reflect the underwriting discipline that has long differentiated Selective and our commitment to pursuing growth where risk-adjusted returns are most attractive.”

“During the second quarter, we celebrated our 100th year in business and 50th year as a publicly traded company – milestones made possible by the talented employees, high-quality distribution partners, customers, and investors who have fueled our success. Having successfully navigated a century of market cycles, we remain confident in our ability to adapt, execute, and create long-term value. The actions we are taking to strengthen our portfolio reflect the same disciplined approach that has guided Selective’s success and position us well to deliver sustainable, profitable growth over the long-term,” concluded Mr. Marchioni.

Overall Insurance Operations

In the second quarter, overall NPW decreased 5%, as we continued to implement rate and non-rate actions to enhance underwriting profitability. Average renewal pure price increased 6.5%, down 3.4 points from a year ago. Our combined ratio was 98.0%, 2.2 points better than a year ago, primarily due to lower catastrophe and non-catastrophe property losses. There was no prior year casualty reserve development in the second quarter in any segment or line of business, compared to 3.8 points of unfavorable prior year reserve development a year ago. This was partially offset by higher current year casualty loss costs.

Overall, insurance segment performance generated 2.3 points of ROE in the second quarter of 2026, up 2.5 points from the second quarter of 2025.

Standard Commercial Lines Segment

In the second quarter, Standard Commercial Lines premiums, which account for 79% of total NPW, decreased 6% from a year ago driven by lower new business. Average renewal pure price increases were 6.5% and retention was 81%, reflecting granular actions to improve our profitability. These actions include driving higher renewal retention on our best-performing business and meaningfully lower retention on poorer-performing business. The second quarter combined ratio was 99.3%, 3.5 points better than a year ago, primarily due to no net prior year casualty reserve development in the current year quarter and lower non-catastrophe property losses, partially offset by higher current year casualty loss costs.

The following table shows the variances in key quarter-to-date and year-to-date measures:

Standard Personal Lines Segment

In the second quarter, Standard Personal Lines premiums, which represent 8% of total NPW, declined 8% and new business decreased 36% from a year ago. Renewal pure price was 8.9% and retention was 79%. The second quarter 2026 combined ratio increased 3.9 points from a year ago, to 95.5%, driven by higher non-catastrophe losses and a higher expense ratio, partially offset by lower catastrophe losses.

Excess and Surplus Lines Segment

For the second quarter, Excess and Surplus Lines premiums, which represent 13% of total NPW, declined 2% from the prior-year period, with average renewal pure price increases of 3.4%. The second quarter 2026 combined ratio was 91.8%, 2.0 points higher than a year ago. The increase was due to higher current year casualty loss costs and non-catastrophe property losses, partially offset by lower catastrophe losses.

Book value per common share increased by $1.39, or 2%, during the first half of 2026. The increase was primarily attributable to $3.69 of net income per diluted common share, partially offset by $1.25 increase in after-tax net unrealized losses on our fixed income securities portfolio and $0.86 in common stockholder dividends. The increase in after-tax net unrealized losses on our fixed income securities portfolio was primarily driven by higher interest rates. In the second quarter of 2026, the Company repurchased $32 million, or 376,131 shares, of common stock at an average price of $84.72.

Selective's Board of Directors also declared:

• A quarterly cash dividend on common stock of $0.43 per common share payable on September 1, 2026, to holders of record as of August 17, 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 September 15, 2026, to holders of record as of August 31, 2026.

Guidance

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

• A GAAP combined ratio of 96.5% to 97.5%, including net catastrophe losses of 6.0 points. Our combined ratio estimate assumes no prior year casualty reserve development, as we record our best estimate each quarter. We do not make assumptions about future reserve development;
• After-tax net investment income of $480 million, up from our initial guidance of $465 million;
• An overall effective tax rate of 21.5%; and
• Weighted average shares of 60.2 million on a fully diluted basis, reflecting the shares repurchased in Six Months 2026 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 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.
