Branchville, NJ - October 21, 2024 - Selective Insurance Group, Inc. (NASDAQ: SIGI) reported financial results for the third quarter ended September 30, 2024, with net income per diluted common share of $1.47 and non-GAAP operating income1 per diluted common share of $1.40. Return on common equity was 12.6% and non-GAAP operating ROE1 was 12.1%.

NPW increased 9% from a year ago driven by accelerating renewal pure price increases and stable Standard Commercial Lines retention. The investments segment generated 13.1 points of annualized ROE in the quarter, as after-tax net investment income was $93 million, up 16% from a year ago.

For the quarter, Selective reported a combined ratio of 99.5% with no net prior year casualty reserve development. Elevated catastrophe losses of $149 million increased the combined ratio by 13.4 points, up from 6.6 points a year ago. Losses resulted from 19 named storms in the quarter, with Hurricane Helene estimated at $85 million of pre-tax losses.

“The continued frequency and severity of storms in the third quarter, including the devastation from Hurricane Helene, underscore our unwavering commitment to our customers, agency partners, and communities. During these challenging times for those impacted by the storms, I thank my colleagues for continuing to deliver superior claims service and supporting customers and claimants,” said John J. Marchioni, Chairman, President and Chief Executive Officer.

“We maintain a disciplined approach to pricing and underwriting our business. Loss trends remain elevated and uncertain, but we continue to be prudent and vigilant in addressing them. In the quarter, renewal pure price increased 10.5%. In Standard Commercial Lines, renewal pure price accelerated to 9.1%. For General Liability, the line most impacted by loss emergence in previous quarters, renewal pure price was 10.2%, up from 7.6% in the second quarter. Importantly, retention was stable in Standard Commercial Lines at 86%.”

“Our primary goal is to consistently achieve our 95% combined ratio target. Although catastrophe losses impacted the quarter, our underlying performance was excellent, reflecting our underwriting and pricing actions and disciplined expense management. We added Nevada, Oregon, and Washington to our Standard Commercial Lines footprint in early October, now covering 35 states. With our strong capital position, financial flexibility, and strategic execution, we are well positioned to face the uncertainty in the external environment,” concluded Mr. Marchioni.

Overall Insurance Operations

For the third quarter, overall NPW increased 9%, or $99 million, from a year ago. Average renewal pure price increased 10.5%, up 3.5 points from a year ago. Selective's 99.5% combined ratio was 2.7 points higher than a year ago, as elevated catastrophe losses were partially offset by lower non-catastrophe property losses and a lower expense ratio. There was no net unfavorable prior year casualty reserve development in either period. The combined ratio excluding net catastrophe losses and prior year casualty reserve development was 86.1%, 4.1 points lower than a year ago.

Overall, our insurance segments increased ROE by 0.6 points in the third quarter of 2024.

Standard Commercial Lines Segment

For the third quarter, Standard Commercial Lines premiums (representing 78% 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 86%. The third quarter combined ratio was 99.2%, up 4.5 points from a year ago, primarily due to catastrophe losses.

There was no net prior year casualty reserve development in the quarter, compared to $3.0 million, or 0.4 points, of favorable development a year ago.

Book value per common share increased by $3.40, or 7%, during the first nine months of 2024. The increase was primarily attributable to a $2.61 decrease in after-tax net unrealized losses on our fixed income securities portfolio and $1.71 of net income per diluted common share, partially offset by $1.05 in common stockholder dividends. The decrease in after-tax net unrealized losses on our fixed income securities portfolio was primarily related to lower interest rates. During the third quarter of 2024, the Company repurchased 103,000 shares of common stock at an average price of $84.34 for $8.7 million. Capacity under the existing repurchase authorization was $75.5 million as of September 30, 2024.

Selective's Board of Directors declared:

•    A 9% increase in the quarterly cash dividend on common stock to $0.38 per common share that is payable December 2, 2024, to holders of record on November 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 December 16, 2024, to holders of record as of December 2, 2024.

Guidance

For 2024, we increased our expected GAAP combined ratio to 102.5%. The change reflects the third quarter's elevated catastrophe losses, partially offset by better-than-expected non-catastrophe property losses. Full-year expectations are as follows:

•A GAAP combined ratio of 102.5%, up 1 point from our prior guidance of 101.5%. Our combined ratio estimate includes net catastrophe losses of 7.5 points, up from prior guidance of 5.5 points. Although too early to provide a specific estimate, we expect losses from Hurricane Milton, which made landfall on October 9, 2024, to be immaterial.

4

---

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.

Forward-Looking Statements

Certain statements in this report, including information incorporated by reference, are “forward-looking statements” defined in the Private Securities Litigation Reform Act of 1995 ("PSLRA"). The PSLRA provides a forward-looking statement safe harbor under the Securities Act of 1933 and the Securities Exchange Act of 1934. These statements discuss our intentions, beliefs, projections, estimations, or forecasts of future events and financial performance. They involve known and unknown risks, uncertainties, and other factors that may cause our or our industry’s actual results, activity levels, or performance to materially differ from those in or implied by the forward-looking statements. In some cases, forward-looking statements include the words “may,” “will,” “could,” “would,” “should,” “expect,” “plan,” “anticipate,” “attribute,” “confident,” “strong,” “target,” “project,” “intend,” “believe,” “estimate,” “predict,” “potential,” “pro forma,” “seek,” “likely,” “continue,” or comparable terms. Our forward-looking statements are only predictions; we cannot guarantee or assure that such expectations will prove correct. We undertake no obligation to publicly update or revise any forward-looking statements for any reason, except as may be required by law.

Factors that could cause our actual results to differ materially from what we project, forecast, or estimate in forward-looking statements include, without limitation:

•Challenging conditions in the economy, global capital markets, the banking sector, and commercial real estate, including prolonged higher inflation, could increase loss costs and negatively impact investment portfolios;

•Deterioration in the public debt, public equity, or private investment markets that could lead to investment losses and interest rate fluctuations;

•Ratings downgrades on individual securities we own could affect investment values and, therefore, statutory surplus;

•The adequacy of our loss reserves and loss expense reserves;

•Frequency and severity of catastrophic events, including natural events that may be impacted by climate change, such as hurricanes, severe convective storms, tornadoes, windstorms, earthquakes, hail, severe winter weather, floods, and fires, and man-made events such as criminal and terrorist acts, including cyber-attacks, explosions, and civil unrest;

•Adverse market, governmental, regulatory, legal, political, or judicial conditions or actions, including social inflation;

•The significant geographic concentration of our business in the eastern portion of the United States;

•The cost, terms and conditions, and availability of reinsurance;

•Our ability to collect on reinsurance and the solvency of our reinsurers;

•The impact of changes in U.S. trade policies and imposition of tariffs on imports that may lead to higher than anticipated inflationary trends for our loss and loss expenses;

•Related to COVID-19, we have successfully defended against payment of COVID-19-related business interruption losses based on our policies' terms, conditions, and exclusions. However, should the highest courts determine otherwise, our loss and loss expenses may increase, our related reserves may not be adequate, and our financial condition and liquidity may be materially impacted.

•Ongoing wars and conflicts impacting global economic, banking, commodity, and financial markets, exacerbating ongoing economic challenges, including inflation and supply chain disruption, which influences insurance loss costs, premiums, and investment valuations;

•Uncertainties related to insurance premium rate increases and business retention;

•Changes in insurance regulations that impact our ability to write and/or cease writing insurance policies in one or more states;

•The effects of data privacy or cyber security laws and regulations on our operations;

•Major defect or failure in our internal controls or information technology and application systems that result in harm to our brand in the marketplace, increased senior executive focus on crisis and reputational management issues, and/or increased expenses, particularly if we experience a significant privacy breach;

•Potential tax or federal financial regulatory reform provisions that could pose certain risks to our operations;

•Our ability to maintain favorable financial ratings, which may include sustainability considerations, from rating agencies, including AM Best, Standard & Poor’s, Moody’s, and Fitch;

•Our entry into new markets and businesses; and

•Other risks and uncertainties we identify in filings with the United States Securities and Exchange Commission, including our Annual Report on Form 10-K and other periodic reports.

Non-GAAP operating income (loss), non-GAAP operating income (loss) per diluted common share, and non-GAAP operating return on common equity are measures comparable to net income (loss) available to common stockholders, net income (loss) available to common stockholders per diluted common share, and return on common equity, respectively, but excludes after-tax net realized and unrealized gains and losses on investments included in net income (loss). Adjusted book value per common share is a measure comparable to book value per common share, but excludes 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 as 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 above.

Safe Harbor Statement We make certain statements and reference other information in this presentation that are “forward-looking statements” as defined in the Private Securities Litigation Reform Act of 1995 (“PSLRA”). The PSLRA provides a forward-looking statement safe harbor under the Securities Act of 1933 and the Securities Exchange Act of 1934. These statements discuss our intentions, beliefs, projections, estimations, or forecasts of future events and financial performance. They involve known and unknown risks, uncertainties, and other factors that may cause our or our industry's actual results, activity levels, or performance to materially differ from those in or implied by the forward-looking statements We discuss factors that could cause our actual results to differ materially from those we project, forecast, or estimate in forward-looking statements in further detail in Selective’s public filings with the United States Securities and Exchange Commission. We undertake no obligation to publicly update or revise any forward-looking statements – whether as a result of new information, future events or otherwise – other than as the federal securities laws may require. This presentation also includes certain non-GAAP financial measures within the meaning of Regulation G, including “non- GAAP operating earnings per share,” “non-GAAP operating income,” “non-GAAP operating return on equity,” and “adjusted book value per share.” Definitions of these non-GAAP measures and a reconciliation to the most comparable GAAP figures are available in our Annual Report on Form 10-K and our Supplemental Investor Package, both found on our website <www.selective.com> under “Investors/Reports & Earnings.” Our commentary references non-GAAP measures we and the investment community use to make it easier to evaluate our insurance business. These non-GAAP measures, however, may not be comparable to similarly titled measures used outside of the insurance industry. Investors are cautioned not to unduly rely on these non-GAAP measures in assessing our overall financial performance. 2
