Total renewal pure price increased 10.3% in the quarter, up from 8.1% a year ago," said John J. Marchioni, Chairman, President and Chief Executive Officer.

Standard Commercial Lines, representing 81% of net premiums written, grew 8% in the quarter with a 96.4% combined ratio. In Standard Commercial Lines, quarterly renewal pure pricing was 9.1% with stable retention of 85%. General Liability pricing accelerated further to 12.0%, up from 10.6% in the fourth quarter of 2024 and 6.5% a year ago."

"In February, we completed a $400 million senior note issuance, enhancing our financial flexibility. The proceeds are being used for general corporate purposes, including supporting organic growth, which remains our primary way to create long-term value for our shareholders," concluded Mr. Marchioni.

Overall Insurance Operations

For the first quarter, overall NPW increased 7% as we focused on rate and non-rate actions to drive profitability while prudently growing the business. Average renewal pure price increased 10.3%, up 2.2 points from a year ago, and our 96.1% combined ratio was 2.1 points better than a year ago. Lower unfavorable prior year casualty reserve development, net catastrophe losses, and non-catastrophe property losses drove the improvement. This was partially offset by higher current year casualty loss costs and a higher expense ratio. Overall, our insurance segments contributed 4.8 points of ROE in the first quarter of 2025.

Standard Commercial Lines Segment

For the first quarter, Standard Commercial Lines premiums (representing 81% of total NPW) grew 8% from a year ago. The premium growth reflected average renewal pure price increases of 9.1% and stable retention of 85%. The first quarter combined ratio was 96.4%, down 2.4 points from a year ago. The improvement was driven by no prior year casualty reserve development compared to 4.2 points of unfavorable prior year casualty reserve development a year ago and lower net catastrophe losses. These improvements were partially offset by higher current year casualty loss costs.

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

Current year casualty loss costs	47.5		44.1	3.4

Standard Personal Lines Segment

For the first quarter, Standard Personal Lines premiums (representing 7% of total NPW) decreased 12% from a year ago due to deliberate profit improvement actions. New business decreased by 58% as we focused on growth in states where we have filed and obtained approvals of adequate rates. Renewal pure price was 24.1% and retention was 75%. The first quarter 2025 combined ratio decreased 7.1 points from a year ago to 98.0%. The improvement reflects the benefit of renewal pure price increases, along with lower catastrophe and non-catastrophe property losses. This was partially offset by 4.8 points of unfavorable prior year casualty reserve development in personal auto.

Excess and Surplus Lines Segment

For the first quarter, Excess and Surplus Lines premiums (representing 12% of total NPW) increased 20% compared to the prior-year period, driven by strong policy count growth, average renewal pure price increases of 8.7%, and new business growth of 4%. The first quarter 2025 combined ratio was 92.5%, up 4.9 points compared to a year ago as higher catastrophe losses were partially offset by lower non-catastrophe property losses.

For the first quarter, after-tax net investment income of $96 million was up 12% from a year ago. The after-tax income yield averaged 4.0% for the fixed income securities portfolio and 3.8% for the overall portfolio. With invested assets per dollar of common stockholders' equity of $3.37 as of March 31, 2025, net investment income generated 12.8 points of annualized ROE.

Book value per common share increased by $2.34, or 5%, during the first quarter of 2025. The increase was primarily attributable to $1.76 of net income per diluted common share and a $1.06 decrease in after-tax net unrealized losses on our fixed income securities portfolio, partially offset by $0.38 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 first quarter of 2025, the Company repurchased 233,611 shares of common stock at an average price of $82.87 for $19.4 million. Capacity under the existing repurchase authorization was $56.1 million as of March 31, 2025.

Selective's Board of Directors declared:

A quarterly cash dividend on common stock of $0.38 per common share that is payable June 2, 2025, to holders of record on May 15, 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 June 16, 2025, to holders of record as of May 30, 2025.

Guidance

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

A GAAP combined ratio of 96% to 97%, including net catastrophe losses of 6 points. Our combined ratio estimate assumes no additional prior year casualty reserve development;
After-tax net investment income of $405 million. A higher asset base due to proceeds from our senior notes issuance should benefit net investment income, while the alternative investments portfolio could face increased valuation headwinds given financial market volatility;
An overall effective tax rate of 21.5%; and
Weighted average shares of 61.5 million on a fully diluted basis, including the shares repurchased in the first quarter of 2025 and assuming no additional repurchases under our existing 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.
