WORCESTER, Mass., May 1, 2024 /PRNewswire/ -- The Hanover Insurance Group, Inc. (NYSE: THG) today reported net income of $115.5 million, or $3.18 per diluted share, in the first quarter of 2024, compared to a net loss of $12.0 million, or $0.34 per basic share, in the prior-year quarter. Operating income(4) was $111.9 million, or $3.08 per diluted share, in the first quarter of 2024, compared to operating income of $4.6 million, or $0.13 per diluted share, in the prior-year quarter.

"The year is off to an excellent start, highlighted by strong underwriting margins and operating return on equity(5) of 15%," said John C. Roche, president and chief executive officer at The Hanover. "In Specialty, we produced another quarter of exceptional profitability, reporting a sub-90s combined ratio while investing in capabilities and positioning ourselves for enhanced growth. We delivered strong performance in Core Commercial, growing our small commercial business by 8% while diligently executing on property profitability actions in middle market. In Personal Lines, we continued to take a disciplined and discerning approach to our growth, as we reposition this book to add more earnings resiliency and to drive strong, sustainable returns. We also began to reaccelerate new business in states where we reached target profitability on a written basis, while continuing to manage micro-concentrations and CAT vulnerability elsewhere, primarily in the Midwest. Our successful execution in the market is a testament to our proven strategy, experienced team and the strong relationships we have with the best independent agents across the country."

"Our overall ex-CAT combined ratio, at 89.5%, improved more than two points in the quarter, validating the effectiveness of pricing and other margin recapture initiatives across our three segments," said Jeffrey M. Farber, executive vice president and chief financial officer at The Hanover. "We continued to get near historical pricing increases in each of our businesses, giving us clear visibility to accelerated improvement in underwriting margins going forward. In the first quarter, we implemented renewal price increases of 23% in Personal Lines, 12% in Core Commercial and 11% in Specialty. And, at the same time, we increased net investment income by 14% to $89.7 million, helped by investment of cash flow and higher new money yields. As we continue to drive our organization forward, we have strong line of sight to delivering on our long-term return on equity target of 14% or higher, and we remain committed to generating superior returns for our valued shareholders."

Core Commercial
Core Commercial operating income before income taxes was $71.5 million in the first quarter of 2024, compared to $11.2 million in the first quarter of 2023. The Core Commercial combined ratio was 93.9%, compared to 104.7% in the prior-year quarter. Catastrophe losses in the first quarter of 2024 were $20.7 million, or 3.9 points of the combined ratio. This compared to catastrophe losses of $63.9 million, or 12.6 points, in the prior-year quarter.

First quarter 2024 results included net favorable prior-year reserve development, excluding catastrophes, of $9.2 million, or 1.7 points, with favorability in each major line of business. This compared to net unfavorable prior-year reserve development, excluding catastrophes, of $3.5 million, or 0.7 points, in the first quarter of 2023.

Core Commercial current accident year combined ratio, excluding catastrophes, remained relatively stable at 91.7%, compared to 91.4% in the prior-year quarter. The current accident year loss and LAE ratio, excluding catastrophes, was 58.5%, in line with the prior-year quarter.

The expense ratio increased by 0.3 points to 33.2% in the first quarter of 2024, compared to the prior-year quarter, primarily due to timing of certain expenses.

Net premiums written were $582.4 million in the quarter, up 3.0% from the prior-year quarter, consisting of 7.7% growth in small commercial and a decline of 2.8% in middle market, driven by targeted underwriting actions. In the first quarter, Core Commercial renewal price increases averaged 11.5%, while average rate increases were 9.3%.

The following table summarizes premiums and the components of the combined ratio for Core Commercial:

Specialty
Specialty operating income before income taxes was $58.8 million in the first quarter of 2024, compared to $48.3 million in the first quarter of 2023. The Specialty combined ratio was 87.6%, compared to 89.9% in the prior-year quarter. Catastrophe losses in the first quarter of 2024 were $7.0 million, or 2.2 points of the combined ratio, compared to $21.5 million, or 6.9 points, in the prior-year quarter.

First quarter 2024 results included net favorable prior-year reserve development, excluding catastrophes, of $1.1 million, or 0.3 points. Net favorable prior-year reserve development, excluding catastrophes, was $18.1 million, or 5.8 points, in the prior-year quarter.

Specialty current accident year combined ratio, excluding catastrophes, decreased 3.1 points to 85.7% in the first quarter of 2024, from 88.8% in the prior-year quarter. The current accident year loss and LAE ratio, excluding catastrophes, decreased 4.8 points to 48.7% in the first quarter of 2024, primarily driven by a lower incidence of large losses in our Hanover specialty industrial business and the benefit of earned pricing above loss trends.

The expense ratio increased by 1.7 points to 37.0% in the first quarter of 2024, compared to the prior-year quarter, primarily due to strategic investments, including talent.

Net premiums written were $339.8 million in the quarter, up 4.8% from the prior-year quarter. In the first quarter, Specialty renewal price increases averaged 11.0%, while average rate increases were 8.4%.

The following table summarizes premiums and the components of the combined ratio for Specialty:

Personal Lines
Personal Lines operating income before income taxes was $18.9 million in the first quarter of 2024, compared to an operating loss before income taxes of $46.6 million in the first quarter of 2023. The Personal Lines combined ratio was 101.0%, compared to 112.2% in the prior-year quarter. Catastrophe losses in the first quarter of 2024 were $59.2 million, or 9.9 points of the combined ratio. This compared to catastrophe losses of $89.6 million, or 16.0 points of the combined ratio, in the prior-year quarter.

First quarter 2024 results included immaterial ex-CAT prior-year reserve development. This compared to net unfavorable prior-year reserve development, excluding catastrophes, of $11.6 million, or 2.1 points, in the prior-year quarter.

Personal Lines current accident year combined ratio, excluding catastrophe losses, decreased 3.0 points to 91.1% in the first quarter of 2024, from 94.1% in the prior-year quarter. The current accident year loss and LAE ratio, excluding catastrophes, decreased 2.4 points from the prior-year quarter to 65.6%, driven by the benefit of earned pricing outpacing loss trends in both personal auto and homeowners, as well as moderated loss trends, particularly in auto collision coverage.

The expense ratio decreased by 0.6 points to 25.5% in the first quarter of 2024, compared to the prior-year quarter, primarily due to lower agency compensation.

Net premiums written were $531.8 million in the quarter, flat compared to the prior-year quarter, as renewal price change moved higher, offset by the impact of profit improvement and catastrophe management actions driving lower policies in force. Personal Lines renewal price increases averaged 22.8%, while average rate increases were 15.8%. Policies in force in the first quarter of 2024 decreased 2.9% compared to the fourth quarter of 2023, driven by a 4.2% decrease in the Midwestern United States.

The following table summarizes premiums and components of the combined ratio for Personal Lines:

Investments
Net investment income was $89.7 million for the first quarter of 2024, above the prior-year quarter by $11.0 million, primarily due to higher bond reinvestment rates, higher partnership income, and continued investment of operational cashflows. Total pre-tax earned yield on the investment portfolio for the first quarter of 2024 was 3.70%, up from 3.34% in the prior-year quarter. The average pre-tax earned yield on fixed maturities was 3.52% for the first quarter of 2024, up from 3.27% in the prior-year quarter.

Net realized and unrealized investment gains recognized in earnings were $5.5 million in the first quarter of 2024, primarily driven by an increase in the fair value of equity securities. This compared to net realized and unrealized investment losses recognized in earnings of $23.0 million in the first quarter of 2023.

The company held $9.2 billion in cash and invested assets on March 31, 2024. Fixed maturities and cash represented approximately 90% of the investment portfolio. Approximately 95% of the company's fixed maturity portfolio is rated investment grade. As of March 31, 2024, net unrealized losses on the fixed maturity portfolio were $630.0 million before income taxes, compared to $588.6 million before income taxes on December 31, 2023.

The company expects to transfer management of its investment-grade fixed maturity portfolio, which accounts for approximately 82% of the company's investments, to an external manager in the second quarter of 2024. In addition, the company expects to exit Opus Investment Management, Inc.'s (Opus) business operations, which provides investment management services to unaffiliated clients, by the end of the second quarter of 2024. The company expects that both changes will have an immaterial impact on its financial results.

Shareholders' Equity and Capital Actions
On March 31, 2024, book value per share was $70.22, up 1.9% from December 31, 2023, primarily driven by operating earnings, partially offset by a decrease in the fair value of fixed maturity investments, as well as the ordinary quarterly cash dividend. Book value per share, excluding net unrealized depreciation on fixed maturity investments, net of tax(7), was $84.01 at March 31, 2024, compared to $81.86 at December 31, 2023. During the quarter, the company did not repurchase any shares of common stock. The company has approximately $330 million of remaining capacity under its existing share repurchase program.

On March 31, 2024, operating subsidiary's statutory capital and surplus was $2.76 billion. This compared to statutory capital and surplus of $2.64 billion on December 31, 2023.

Non-GAAP Financial Measures
As discussed on page 40 of the company's Annual Report on Form 10-K for the year ended December 31, 2023, the company uses non-GAAP financial measures as important measures of its operating performance, including operating income (loss), operating income (loss) before interest expense and income taxes, operating income (loss) per diluted (basic) share, and components of the combined ratio, both excluding and/or including catastrophe losses, prior-year reserve development and the expense ratio. Management believes these non-GAAP financial measures are important indications of the company's operating performance. The definition of other non-GAAP financial measures and terms can be found in the 2023 Annual Report on pages 64-67.

Operating income (loss) and operating income (loss) per diluted (basic) share are non-GAAP measures. They are defined as net income (loss) excluding the after-tax impact of net realized and unrealized investment gains (losses), gains and/or losses on the repayment of debt, other non-operating items, and results from discontinued operations. Net realized and unrealized investment gains (losses), which include changes in the fair value of equity securities still held, are excluded for purposes of presenting operating income (loss), as they are, to a certain extent, determined by interest rates, financial markets and the timing of sales. Operating income (loss) also excludes net gains and losses from disposals of businesses, gains and losses related to the repayment of debt, costs to acquire businesses, restructuring costs, the cumulative effect of accounting changes, and certain other items. Operating income (loss) is the sum of the segment income (loss) from: Core Commercial, Specialty, Personal Lines, and Other, after interest expense and income taxes. In reference to one of the company's four reporting segments, "operating income (loss)" is the segment income (loss) before both interest expense and income taxes. The company also uses "operating income (loss) per diluted (basic) share" (which is after both interest expense and income taxes). Operating income per share is calculated by dividing operating income by the weighted average number of diluted shares of common stock. Operating loss per share is calculated by dividing operating loss by the weighted average number of basic shares of common stock due to antidilution. The company believes that metrics of operating income (loss) and operating income (loss) in relation to its four reporting segments provide investors with a valuable measure of the performance of the company's continuing businesses because they highlight the portion of net income (loss) attributable to the core operations of the business. Net income (loss) is the most directly comparable GAAP measure for operating income (loss) (and operating income (loss) before income taxes) and measures of operating income (loss) that exclude the effects of catastrophe losses and/or prior-year reserve development should not be misconstrued as substitutes for income (loss) before income taxes or net income (loss) determined in accordance with GAAP. A reconciliation of operating income (loss) to net income (loss) for the relevant periods is included on page 10 of this news release and in the Financial Supplement.

Operating return on average equity (ROE) is a non-GAAP measure. See end note (5) for a detailed explanation of how this measure is calculated. Operating ROE is based on non-GAAP operating income (loss). In addition, the portion of shareholder equity attributed to unrealized appreciation (depreciation) on fixed maturity investments, net of tax, is excluded. The company believes this measure is helpful in that it provides insight to the capital used by, and results of, the continuing business exclusive of interest expense, income taxes, and other non-operating items. These measures should not be misconstrued as substitutes for GAAP ROE, which is based on net income (loss) and shareholders' equity of the entire company and without adjustments.

The company may provide measures of operating income (loss) and combined ratios that exclude the impact of catastrophe losses (which in all respects include prior accident year catastrophe loss development). A catastrophe is a severe loss, resulting from natural or manmade events including, but is not limited to, hurricanes, tornadoes and other windstorms, hail, flood, earthquakes, fire, explosions, severe winter weather and other convective storms, riots, and terrorism. Due to the unique characteristics of each catastrophe loss, there is an inherent inability to reasonably estimate the timing or loss amount in advance. The company believes a separate discussion excluding the effects of catastrophe losses is meaningful to understand the underlying trends and variability of earnings, loss and combined ratio results, among others.

Book value per share is total shareholders' equity divided by the number of common shares outstanding. Book value per share excluding net unrealized appreciation (depreciation) on fixed maturity investments, net of tax, is total shareholders' equity excluding the after-tax effect of unrealized appreciation (depreciation) on fixed maturities and market risk divided by the number of common shares outstanding.

Prior accident year reserve development, which can either be favorable or unfavorable, represents changes in the company's estimate of costs related to claims from prior years. Calendar year loss and loss adjustment expense (LAE) ratios determined in accordance with GAAP, excluding prior accident year reserve development, are sometimes referred to as "current accident year loss ratios." The company believes a discussion of loss and combined ratios, excluding prior accident year reserve development, is helpful since it provides insight into both estimates of current accident year results and the accuracy of prior-year estimates.

The loss and combined ratios in accordance with GAAP are the most directly comparable GAAP measures for the loss and combined ratios calculated excluding the effects of catastrophe losses and/or prior-year reserve development. The presentation of loss and combined ratios calculated excluding the effects of catastrophe losses and/or prior-year reserve development should not be misconstrued as substitutes for the loss and/or combined ratios determined in accordance with GAAP.
