Net Income per Diluted Common Share of $1.36 and Non-GAAP Operating Income¹ per Diluted Common Share of $1.31;

Return on Common Equity ("ROE") of 10.7% and Non-GAAP Operating ROE¹ of 10.3%

In the second quarter of 2025:

Net premiums written ("NPW") increased 5% from the second quarter of 2024;
The GAAP combined ratio was 100.2%, compared to 116.1% in the second quarter of 2024;
Commercial Lines renewal pure price increases averaged 8.9%, up 1.0 point from 7.9% in the second quarter of 2024;
After-tax net investment income was $101 million, up 18% from the second quarter of 2024;
Book value per common share was $52.09, up 3% from last quarter; and
Adjusted book value per common share¹ was $54.48, up 2% from last quarter.

Selective Insurance Group, Inc. (NASDAQ:SIGI) reported financial results for the second quarter ended June 30, 2025, with net income per diluted common share of $1.36 and non-GAAP operating income¹ per diluted common share of $1.31. ROE was 10.7% and non-GAAP operating ROE¹ was 10.3%.

For the quarter, Selective's combined ratio was 100.2%. Catastrophe losses were 6.7 points, and net unfavorable prior year casualty reserve development was 3.8 points, driven by $45 million of reserve strengthening in commercial lines. NPW grew 5% from a year ago driven by renewal pure price increases of 9.9%. Net investment income increased 18% from a year ago, to $101 million after-tax, and generated 13.0 points of annualized ROE in the quarter.

"The combined ratio of 100.2% reflects continued pressures from elevated severities due to social inflation, which drove unfavorable prior year casualty reserve development in the quarter," said John J. Marchioni, Chairman, President and Chief Executive Officer.

"To address the continued elevated level of loss costs, we are diligently working to improve profitability through pricing and underwriting actions. Our unique operating model and franchise value distribution enable us to focus on appropriate risk selection and granular pricing. This quarter, our disciplined approach contributed to slowing top-line growth."

"We believe that strong execution of our strategic initiatives will position us to deliver profitable growth in the current market environment," concluded Mr. Marchioni.

Overall Insurance Operations

For the second quarter, overall NPW increased 5%, as we focused on rate and non-rate actions to improve profitability while prudently growing the business. Average renewal pure price increased 9.9%, up 0.8 points from a year ago. Our 100.2% combined ratio included 3.8 points, or $45 million, of unfavorable prior year casualty reserve development. The combined ratio was 15.9 points better than a year ago, driven by lower unfavorable prior year casualty reserve development, net catastrophe losses, and non-catastrophe property losses.

Overall, insurance segment performance reduced ROE by 0.2 points in the second quarter of 2025.

Standard Commercial Lines Segment

For the second quarter, Standard Commercial Lines premiums (representing 79% of total NPW) grew 6% from a year ago. The premium growth reflected average renewal pure price increases of 8.9% and lower retention of 83%. The second quarter combined ratio was 102.8%, down 16.0 points from a year ago. Lower unfavorable prior year casualty reserve development, net catastrophe losses, and non-catastrophe property losses drove the improvement.

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

Standard Commercial Lines Segment	Quarter ended June 30,				Change			Year-to-Date June 30,				Change

Current year casualty loss costs		46.8		46.4	0.4				47.2		45.2	2.0

Standard Personal Lines Segment

For the second quarter, our deliberate profit improvement actions caused Standard Personal Lines premiums (representing 9% of total NPW) to decline 5% from a year ago and new business to fall 41%. We continue to focus on growth in states where we have filed and obtained adequate rate approvals. Renewal pure price was 19.0% and retention was 79%. The second quarter 2025 combined ratio improved 26.5 points from a year ago to 91.6%, benefiting from renewal pure price increases, lower catastrophe losses, non-catastrophe property losses, and current year casualty loss costs.

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

Excess and Surplus Lines Segment

For the second quarter, Excess and Surplus Lines premiums (representing 12% of total NPW) increased 9% from the prior-year period, driven by average renewal pure price increases of 9.3%. The second quarter 2025 combined ratio was 89.8%, 4.8 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.

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

For the second quarter, after-tax net investment income of $101 million was up 18% from a year ago. The after-tax income yield averaged 4.2% for the fixed income securities portfolio and 3.9% for the overall portfolio. With invested assets per dollar of common stockholders' equity of $3.33 as of June 30, 2025, net investment income generated 13.0 points of annualized ROE.

Book value per common share increased by $4.10, or 9%, during the first half of 2025. The increase was primarily attributable to $3.12 of net income per diluted common share and a $1.74 decrease in after-tax net unrealized losses on our fixed income securities portfolio, partially offset by $0.76 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 second quarter of 2025, the Company did not repurchase any shares of common stock. Capacity under the existing repurchase authorization was $56.1 million as of June 30, 2025.

Selective's Board of Directors declared:

A quarterly cash dividend on common stock of $0.38 per common share that is payable September 2, 2025, to holders of record on August 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 September 15, 2025, to holders of record as of August 29, 2025.

Guidance

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

A GAAP combined ratio of 97% to 98%, up 1 point from prior guidance of 96% to 97%, including net catastrophe losses of 6 points and the impact of prior year casualty reserve development reported through the second 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 $415 million, up from prior guidance of $405 million;
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 half 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.
