Selective Insurance Group, Inc. (NASDAQ:SIGI) reported financial results for the first quarter ended March 31, 2026, with net income per diluted common share of $1.58 and non-GAAP operating income¹ per diluted common share of $1.69. ROE was 11.2% and non-GAAP operating ROE¹ was 12.0%.

For the quarter, Selective's combined ratio was 98.3%. Catastrophe losses were 6.2 points, and there was no net prior year casualty reserve development. NPW decreased 1% from a year ago due to a 6% decrease in Standard Personal Lines and a 1% decrease in Standard Commercial Lines. Renewal pure price increases were 7.2%. Net investment income increased 18% from a year ago, to $113 million after-tax, generating 13.3 points of annualized ROE in the quarter.

"Our operating ROE of 12% this quarter was in-line with our long-term target and marked our seventh consecutive quarter of double-digit operating returns. We delivered a solid start to the year, which keeps us on track to achieve our 2026 guidance. In addition, we returned 57% of after-tax net income through our regular dividend and $30 million of share repurchases, reinforcing our commitment to delivering long-term value," said John J. Marchioni, Chairman, President and Chief Executive Officer.

"Net premiums written decreased modestly in the quarter, reflecting a competitive environment and deliberate actions to further strengthen our performance. We view growth as an outcome of disciplined execution, and remain focused on delivering target underwriting profitability. This is supported by granular pricing, risk selection, and claims discipline."

"With our talented employees, high-quality distribution partner relationships, and strong capital position, we are continuing to make investments to support diversifying, profitable growth across our business. We believe we are well positioned for the opportunities in front of us," concluded Mr. Marchioni.

Overall Insurance Operations

In the first quarter, overall NPW decreased 1%, as we implemented rate and non-rate actions to enhance underwriting profitability. Average renewal pure price increased 7.2%, down 3.1 points from a year ago. Our combined ratio was 98.3%, 2.2 points higher than a year ago, primarily due to higher catastrophe losses. There was no prior year casualty reserve development in the first quarter in any segment or line of business.

Overall, insurance segment performance generated 2.0 points of ROE in the first quarter of 2026, down 2.8 points from the first quarter of 2025.

Standard Commercial Lines Segment

In the first quarter, Standard Commercial Lines premiums, which account for 81% of total NPW, decreased 1% from a year ago driven by lower new business. Average renewal pure price increases were 7.1% and retention was 82% reflecting granular actions to improve our profitability. The first quarter combined ratio was 100.2%, 3.8 points higher than a year ago, primarily due to catastrophe losses.

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

In the first quarter, Standard Personal Lines premiums, which represent 7% of total NPW, declined 6% and new business decreased 15% from a year ago. Renewal pure price was 10.6% and retention was 78%. Despite higher catastrophe losses, the first quarter 2026 combined ratio improved 5.2 points from a year ago to 92.8%, reflecting our deliberate profit improvement actions.

Excess and Surplus Lines Segment

The first quarter 2026 combined ratio was 89.5%, 3.0 points better than a year ago. The improvement was due to lower catastrophe losses, partly offset by higher non-catastrophe property losses.

The after-tax income yield averaged 4.2% for the fixed income securities portfolio and 4.0% for the overall portfolio.

Book value per common share decreased by $0.16 during the first quarter of 2026. The decrease was primarily attributable to a $1.20 increase in after-tax net unrealized losses on our fixed income securities portfolio and $0.43 in common stockholder dividends, partially offset by $1.58 of net income per diluted common share. The increase in after-tax net unrealized losses on our fixed income securities portfolio was primarily driven by higher interest rates. In the first quarter of 2026, the Company repurchased $30 million, or 337,303 shares, of common stock at an average price of $88.94.

Selective's Board of Directors also declared:

A quarterly cash dividend on common stock of $0.43 per common share payable on June 1, 2026, to holders of record as of May 15, 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 June 15, 2026, to holders of record as of May 29, 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 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 $465 million;
An overall effective tax rate of 21.5%; and
Weighted average shares of 60.5 million on a fully diluted basis, down from 61 million in our initial guidance. This reflects share repurchases in First Quarter 2026, but does not make assumptions about future share repurchases under our existing 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.
