Branchville, NJ - July 18, 2024 - Selective Insurance Group, Inc. (NASDAQ: SIGI) reported financial results for the second quarter ended June 30, 2024, with a net loss per diluted common share of $1.08 and a non-GAAP operating loss1 per diluted common share of $1.10.

For the quarter, Selective reported a combined ratio of 116.1%. Net unfavorable prior year casualty reserve development of $176 million increased the combined ratio by 16.3 points. Catastrophe losses of $91 million increased the combined ratio by 8.4 points. NPW increased 13% from a year ago, with growth across all three insurance segments. After-tax net investment income was $86 million, up 11% from a year ago. Non-GAAP operating ROE1 was (9.6)%.

“This was a challenging quarter. We did not meet our high standard as underwriting performance fell below our target. The unfavorable prior year casualty reserve development was driven by elevated loss emergence in the quarter reflecting higher severity that we attribute to social inflation. Our reserving action is predicated on our in-depth quarterly reserve review and further strengthening to address elevated and uncertain loss trends,” said John J. Marchioni, Chairman, President and Chief Executive Officer.

“We have a very stable underwriting portfolio. To address our updated view of loss costs, we are responding with additional price increases. Our renewal pure price increase across all insurance segments was 9.1% in the quarter, including 7.9% for Standard Commercial Lines. General liability renewal pure pricing increased to 7.6%, up over a point from the first quarter. We expect Standard Commercial Lines renewal pure price will trend higher in the second half of 2024.”

“We maintain our disciplined focus and execution in the areas of risk selection, pricing, and claims management in the face of this challenging and dynamic loss trend environment. Our capital position remains strong and our underlying combined ratio of 91.4% positions us well moving forward. We are confident that we will quickly re-establish our strong earnings profile, consistently meeting or exceeding our 12% operating ROE target,” concluded Mr. Marchioni.

For the second quarter, overall NPW increased 13%, or $141 million, from a year ago, reflecting new business growth and effective management of our renewal portfolio. Average renewal pure price increased 9.1%, up 2.7 points from a year ago. Selective's 116.1% combined ratio in the quarter was 15.9 points higher than a year ago, primarily due to prior year casualty reserve development. Net unfavorable prior year casualty reserve development totaled $176 million, increasing the combined ratio by 16.3 points. A year ago, prior year casualty reserve development was a favorable $3.5 million, reducing the combined ratio by 0.4 points. The combined ratio, excluding net catastrophe losses and prior year casualty reserve development, was 91.4%, 1.4 points higher than a year ago.

Overall, our insurance segments reduced ROE by 19.9 points in the second quarter of 2024.

For the second quarter, Standard Commercial Lines premiums (representing 79% of total NPW) grew 11% from a year ago. The premium growth reflected average renewal pure price increases of 7.9%, new business growth of 6%, strong exposure growth, and stable retention of 85%. The second quarter combined ratio was 118.8%, up 21.7 points from a year ago, primarily due to prior year casualty reserve development.

Prior year casualty reserve development in the quarter was an unfavorable $176 million, or 20.6 points, compared to $7.5 million, or 1.0 point, of favorable development a year ago. This quarter's prior year casualty reserve development included unfavorable general liability development of $166 million, primarily from increased severities in accident years 2020 through 2023 and $10 million of unfavorable commercial auto development. A year ago, workers compensation was the source of the favorable prior year casualty reserve development.

For the second quarter, Standard Personal Lines premiums (representing 9% of total NPW) increased 6% from a year ago with renewal pure price of 20.7% and higher average policy sizes. Retention was 78%, down 10 points from a year ago, and new business decreased 32% due to deliberate profit improvement actions. The second quarter 2024 combined ratio improved by 8.4 points from a year ago to 118.1%. The loss ratio improved 5.7 points, with no prior year casualty reserve development in the quarter. A year ago personal auto had $4 million in unfavorable prior year casualty reserve development. The underwriting expense ratio also improved by 2.7 points.

For the second quarter, Excess and Surplus Lines premiums (representing 12% of total NPW) increased 39% compared to the prior-year period, driven by new business growth of 54% and average renewal pure price increases of 6.4%. The second quarter 2024 combined ratio was 94.6%, down 6.1 points compared to a year ago primarily due to lower catastrophe losses.

For the second quarter, after-tax net investment income of $86 million was up 11% from a year ago, primarily from the fixed income securities portfolio. For the quarter, the after-tax income yield averaged 3.9% for the overall and the fixed income securities portfolios. With the increased portfolio yield and invested assets per dollar of common stockholders' equity of $3.31 as of June 30, 2024, the Investments segment generated 12.5 points of non-GAAP operating ROE in the quarter.

Book value per common share decreased by $0.68, or 1% during the first half of 2024. The decrease was primarily attributable to $0.70 in common stockholder dividends and a $0.36 increase in after-tax net unrealized losses on our fixed income securities portfolio, partially offset by $0.24 of net income per diluted common share. The increase in after-tax net unrealized losses on our fixed income securities portfolio primarily related to higher interest rates. During the first half of 2024, the Company did not repurchase any shares of common stock. Capacity under the existing repurchase authorization was $84.2 million as of June 30, 2024.

Selective's Board of Directors declared:

•    A quarterly cash dividend on common stock of $0.35 per common share that is payable September 3, 2024, to holders of record on August 15, 2024; 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 16, 2024, to holders of record as of August 30, 2024.

For 2024, we increased our expected GAAP combined ratio to 101.5%. The change reflects unfavorable prior year casualty reserve development, elevated catastrophe losses in the first half of the year, and increased current year loss costs. Full-year expectations are as follows:

•A GAAP combined ratio of 101.5%, up five points from our prior guidance of 96.5%. Our combined ratio estimate includes net catastrophe losses of 5.5 points, up from prior guidance of 5.0 points. Our combined ratio estimate assumes no additional prior year casualty reserve development;

•After-tax net investment income of $360 million that includes $32 million from alternative investments;

•An overall effective tax rate of approximately 21.0%, which assumes an effective tax rate of 20.5% for net investment income and 21% for all other items; and

•Weighted average shares of 61.5 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 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.
