Branchville, NJ - April 28, 2021 - Selective Insurance Group, Inc. (NASDAQ: SIGI) today reported financial results for the first quarter ended March 31, 2021, with net income per diluted common share of $1.77 and non-GAAP operating income1 per diluted common share of $1.70.

“Our excellent first-quarter financial performance is a testament to our continued successful execution of our strategy focused on generating disciplined and profitable growth. We reported a strong 16.2% non-GAAP operating ROE, non-GAAP operating income per diluted common share of $1.70, and an impressive 89.3% combined ratio. Our commercial lines NPW increased 28% from a year ago, of which 16 points were due to the COVID-19-related $75 million return audit and mid-term endorsement premium accrual that reduced NPW in 2020. Commercial lines growth was driven by renewal pure price increases of 5.7% and continued solid retention of 86%. Each of our segments generated profitable results, with Investments a major contributor this quarter,” said John Marchioni, President and CEO.

“We are extremely proud of our successful track record in recent years of balancing growth with profitability, and consistently generating strong ROEs. Our results, in large part, have been driven by our superior distribution partner relationships, sophisticated underwriting tools and technologies, best-in-class customer experience capabilities, and culture of underwriting discipline. Our capital and liquidity position is the strongest at any time in our history. As we look to the remainder of 2021, we are well positioned to build on that successful record,” continued Mr. Marchioni.

Overall Insurance Operations

For the first quarter, overall NPW increased 23% from a year ago, of which 12 points were due to the COVID-19-related $75 million return audit and mid-term endorsement premium accrual that reduced NPW in 2020. The increase in NPW also reflected solid retention and strong overall renewal pure price increases of 5.4%. Our combined ratio was an excellent 89.3% in the quarter, compared to 96.7% in the prior year period, benefiting from favorable reserve development and strong underlying profitability. Our Insurance Operations generated 9.7 points of annualized ROE in the quarter.

NPW growth was also driven by renewal pure price increases of 5.7% and strong retention of 86%.

Investments Segment

For the first quarter, net investment income, after-tax, of $56 million was up a solid 24% compared to first quarter 2020.

Solid operating cash flow of $130 million equated to 16% of NPW for the quarter and contributed to the growth in invested assets. Invested assets per dollar of common stockholders' equity was $2.97 at March 31, 2021. For the quarter, the after-tax earned income yield on the portfolio averaged 3.0%, and the investment portfolio generated 8.9 points of annualized non-GAAP operating ROE.

During the first quarter, the Company repurchased 52,781 shares at an average price of $64.49 per share for a total of $3.4 million.

1Reconciliation of Net Income Available to Common Stockholders to Non-GAAP Operating Income and Certain Other Non-GAAP Measures

Non-GAAP operating income, non-GAAP operating income per diluted common share, and non-GAAP operating return on common equity differ from net income available to common stockholders, net income 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. They are used as important financial measures by management, analysts, and investors, because the timing of realized investment gains and losses on sales of securities in any given period is largely discretionary. In addition, net realized and unrealized gains and losses on investments that are charged to earnings could distort the analysis of trends. These operating measurements are not intended as a substitute for net income available to common stockholders, net income available to common stockholders per diluted common share, and return on common equity prepared in accordance with U.S. generally accepted accounting principles (GAAP). Reconciliations of net income available to common stockholders, net income available to common stockholders per diluted common share, and return on common equity to non-GAAP operating income, non-GAAP operating income per diluted common share, and non-GAAP operating return on common equity, respectively, are provided in the tables below.

Note: All amounts included in this release exclude intercompany transactions.

Forward-Looking Statements

Certain statements in this report, including information incorporated by reference, are “forward-looking statements” as that term is defined in the Private Securities Litigation Reform Act of 1995 ("PSLRA"). The PSLRA provides a safe harbor under the Securities Act of 1933 and the Securities Exchange Act of 1934 for forward-looking statements. These statements relate to our intentions, beliefs, projections, estimations, or forecasts of future events or our future financial performance and involve known and unknown risks, uncertainties, and other factors that may cause our or our industry’s actual results, levels of activity, or performance to be materially different from those expressed or implied by the forward-looking statements. In some cases, you can identify forward-looking statements by use of words such as “may,” “will,” “could,” “would,” “should,” “expect,” “plan,” “anticipate,” “target,” “project,” “intend,” “believe,” “estimate,” “predict,” “potential,” “pro forma,” “seek,” “likely,” or “continue” or other comparable terminology. These statements are only predictions, and we can give no assurance that such expectations will prove to be correct. We undertake no obligation, other than as may be required under the federal securities laws, to publicly update or revise any forward-looking statements for any reason.

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

•Related to COVID-19:

◦Governmental directives to contain or delay the spread of the COVID-19 pandemic have disrupted ordinary business commerce and impacted financial markets. These governmental actions, the extent, duration, and possible alteration based on future COVID-19-related developments that we cannot predict, could materially and adversely affect our results of operations, net investment income, financial position, and liquidity.

◦The amount of premium we record may be reduced and our underwriting results may be adversely impacted by (i) voluntary premium credits on in-force commercial and personal automobile policies, (ii) state insurance commissioner or other regulatory directives to implement premium-based credit in lines other than commercial and personal automobile, and we may be required to return more premium than warranted by our filed rating plans and actual loss experience, (iii) the effects of our voluntary efforts or the directives from various state insurance regulators to extend individualized payment flexibility and suspend policy cancellations, late payment notices, and late or reinstatement fees, (iv) return premiums that could be significant because our general liability and workers compensation policies provide for premium audit of revenues and payrolls, and (v) collectability of premiums, which may be impacted by policyholder financial distress and insolvency.

◦Our loss and loss expenses may increase, our related reserves may not be adequate, and our financial condition and liquidity may be materially impacted if litigation or changes in statutory or common law (i) require payment of COVID-19-related business interruption losses despite contrary terms, conditions, and exclusions in our policies or (ii) presume that COVID-19 is a work-related illness compensable under workers compensation policies for employees who contract the virus, regardless of whether they worked in industries defined as essential in various COVID-19-related governmental directives or interacted with the public as part of their job duties.

◦Our net investment income may be impacted by the significant equity and debt financial market volatility resulting from the COVID-19 pandemic and the related governmental orders because (i) financial market volatility is reflected in our alternative investments’ performance, (ii) increased spreads on fixed income securities may create mark-to-market investment valuation losses that reduce unrealized capital gains and impact GAAP equity, and (iii) net realized losses may increase if we intend to sell more securities, particularly in asset classes that are more significantly impacted by COVID-19-related governmental directives and to which the Federal Reserve Board is providing liquidity and structural support.

•Difficult conditions in global capital markets and the economy;

•Deterioration in the public debt and equity markets and private investment marketplace 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 natural and man-made catastrophic events, including without limitation hurricanes, tornadoes, windstorms, earthquakes, hail, terrorism, including cyber-attacks, explosions, severe winter weather, floods, and fires;

•Adverse market, governmental, regulatory, legal, or judicial conditions or actions;

•The 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;

•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;

•Recent federal financial regulatory reform provisions that could pose certain risks to our operations;

•Our ability to maintain favorable ratings 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, but not limited to, our Annual Report on Form 10-K and other periodic reports.

These risk factors may not be exhaustive. We operate in a continually changing business environment, and new risk factors that we cannot predict or assess may emerge from time-to-time.
