WORCESTER, Mass., July 28, 2026 - The Hanover Insurance Group, Inc. (NYSE: THG) today reported net income of $191.6 million, or $5.38 per diluted share, in the second quarter of 2026, compared to $157.1 million, or $4.30 per diluted share, in the prior-year quarter.

“Our very successful second quarter is a testament to the strength of our business model, the durable earnings power we have built across The Hanover and the disciplined execution of our team,” said John C. Roche, president and chief executive officer at The Hanover. “We posted operating return on equity of approximately 20% and operating earnings of $5.31 per share, both second quarter records, as well as accelerated top-line premium growth. We are effectively navigating evolving market conditions, and achieving healthy pricing, while building growth momentum in the most attractive areas of our portfolio.”

“This quarter reflects the talent of our employees, the strength of our leadership team, the depth of our agency relationships and the trust our customers place in us every day,” said Roche. “As we announced earlier this month, I plan to retire at the end of 2026. It's been a great honor to serve the last nine years as CEO, and I could not be more optimistic about The Hanover’s future. Dick Lavey has been one of the key architects of our strategy and the transformation of our company. We

will continue to work closely together through the remainder of the year to ensure a seamless transition. Dick's leadership, expertise and strategic vision position him well to successfully lead The Hanover into its next chapter.”

“We are pleased with our excellent performance, including outstanding underwriting profitability as demonstrated by our combined ratio of 91.2%, and 85.5% excluding catastrophes,” said Jeffrey M. Farber, executive vice president and chief financial officer at The Hanover. “Additionally, we delivered robust net investment income, up 13%, driven by higher earned yields and strong operating cash flows, while continued favorable development reinforces our confidence in the strength of our reserve position. The profitability of our business continues to build capital, enabling increased share repurchases while maintaining the balance sheet strength and financial flexibility for future growth opportunities and deployment. Following a really strong start to the year, we enter the second half of 2026 with confidence, supported by our varied earnings streams, resilient balance sheet and disciplined focus on capital allocation.”

This compared to catastrophe losses of $22.7 million, or 4.1 points, in the prior-year quarter.

Additionally, the loss ratio in the prior-year quarter benefited from lower-than-usual property losses.

The expense ratio decreased by 0.4 points, to 32.5%, in the second quarter of 2026, compared to the prior-year quarter, reflecting fixed cost leverage and efficiency gains.

Net premiums written were $574.8 million in the second quarter of 2026, up 7.2% from the prior-year quarter, an acceleration from the first quarter of 2026, reflecting growth of 6.0% in small commercial and 9.4% in middle market (approximately 7% growth in middle market excluding non-recurring items).

Personal Lines

Personal Lines operating income before income taxes was $104.9 million in the second quarter of 2026, compared to $57.4 million in the second quarter of 2025. The Personal Lines combined ratio was 88.9%, compared to 95.5% in the prior-year quarter. Catastrophe losses in the second quarter of 2026 were $55.4 million, or 8.5 points of the combined ratio. This compared to catastrophe losses of $70.2 million, or 11.1 points of the combined ratio, in the prior-year quarter.

Second quarter 2026 results included net favorable prior-year reserve development, excluding catastrophes, of $10.1 million, or 1.5 points, compared to $2.6 million, or 0.4 points, in the second quarter of 2025.

The current accident year loss and LAE ratio, excluding catastrophes, decreased 4.2 points from the prior-year quarter, to 55.6%, driven by the continued benefit of earned pricing outpacing loss trends and benign property claims frequency, as well as lower large loss experience in homeowners in the quarter.

The expense ratio increased by 1.3 points, to 26.3%, in the second quarter of 2026, compared to the prior-year quarter, primarily reflecting the timing of variable agency compensation expenses due to meaningfully better-than-expected results to date.

Net premiums written were $697.6 million in the second quarter of 2026, up 2.6% compared to the prior-year quarter. The increase was primarily due to higher new business, and to a lesser extent, the impact of renewal price increases. Personal Lines renewal price increases averaged 8.7%, including average rate increases of 4.8%. Policies in force (PIF) in the second quarter of 2026 were essentially flat compared to the first quarter of 2026.

Investments

Net investment income was $119.6 million in the second quarter of 2026, an increase of 13.4% from the prior-year quarter, primarily due to the continued investment of cashflows from operations and the impact of higher earned yields on the fixed maturity investment portfolio. Total pre-tax earned yield on the investment portfolio for the second quarter of 2026 was 4.28%, up from 4.11% in the prior-year quarter. The average pre-tax earned yield on fixed maturities was 4.45% for the second quarter of 2026, up from 4.24% in the prior-year quarter.

Net realized and unrealized investment gains recognized in earnings were $2.8 million in the second quarter of 2026. This compared to net realized and unrealized investment losses recognized in earnings of $2.5 million in the second quarter of 2025.

The company held $11.2 billion in cash and invested assets at June 30, 2026. Fixed maturities and cash represented approximately 93% of the investment portfolio. Approximately 95% of the company’s fixed maturity portfolio is rated investment grade. As of June 30, 2026, net unrealized losses on the fixed maturity portfolio were $259.5 million before income taxes, compared to $235.6 million at March 31, 2026.

Shareholders’ Equity and Capital Actions

At June 30, 2026, book value per share was $105.40, up 3.5% from March 31, 2026, driven by strong earnings, partially offset by share repurchases, the ordinary quarterly cash dividends, and an increase in the unrealized loss position on the fixed maturity portfolio. Book value per share, excluding net unrealized depreciation on fixed maturity investments, net of tax, was $111.26 at June 30, 2026, up 3.8% from March 31, 2026.

At June 30, 2026, operating insurance company’s statutory capital and surplus was $3.54 billion, slightly higher compared to March 31, 2026.

The company repurchased approximately 291,000 shares of common stock in the second quarter of 2026, totaling approximately $55 million. Year-to-date through July 24th, the company has repurchased approximately 827,000 shares, totaling approximately $149 million.

Forward-Looking Statements and Non-GAAP Financial Measures

Forward-Looking Statements

Certain statements in this document may be “forward-looking statements” as defined in the Private Securities Litigation Reform Act of 1995. Forward-looking statements may address, among other things, expectations regarding our growth, the strength of our reserves, certain statements regarding our performance for the remainder of 2026 and beyond, as well as our expectations, intentions and other statements that are not historical facts. Words such as: “believes,” “anticipates,” “expects,” “intends,” “may,” “projects,” “plan,” “likely,” “potential,” “targeted,” “forecasts,” “should,” “could,” “continue,” and other similar expressions are intended to identify forward-looking statements. Forward-looking statements by their nature address matters that are, to different degrees, uncertain. The company cautions investors that any such forward-looking statements are estimates, beliefs, expectations and/or projections that involve significant judgment, are not guarantees and are not necessarily indicative of future performance. Actual results could differ materially from those anticipated. Investors should not place undue reliance on forward-looking statements, which speak only as of the date they are made and should understand the risks and uncertainties inherent in or particular to the company’s business. Some of the factors that could cause actual results to differ include, but are not limited to: changes in the demand for our products; risks and uncertainties related to our growth and operating strategies, including our ability to attract, grow and retain profitable policies in force, to increase rates commensurate with, or in excess of, loss trends, and to manage expenses and execute strategic initiatives effectively; adverse claims experience or changes in our estimates of loss and loss adjustment expense reserves, including those arising from catastrophes, inflationary pressures or global unrest, which may result in lower current year underwriting results or adverse loss development, and which could negatively impact our carried reserves; uncertainties with respect to the long-term profitability of our products, including with respect to newer products, or longer-tail products covering casualty losses; disruption in our distribution channels, including the loss or disruption of our independent agency channel, and the impact of competition and consolidation in the industry and among agents and brokers; changes in frequency and loss severity trends, exacerbated by fluctuations in economic conditions; changes in regulatory, legislative, economic, market and political conditions, particularly with respect to rates, policy terms and conditions, the use of artificial intelligence and other technologies, privacy and data security, payment flexibility, and regions where we have geographical concentration; volatile and unpredictable developments, including severe weather (whether arising from changing climate conditions or weather patterns, or otherwise) and other natural physical events, catastrophes, pandemics, civil unrest, war, global conflicts, and terrorist actions, and the uncertainty in estimating the resulting losses; and, other risks, uncertainties and factors discussed in the company's most recently filed quarterly report on Form 10-Q and its 2025 Annual Report filed on Form 10-K and in the company's other filings with the U.S. Securities and Exchange Commission or in materials incorporated therein by reference. The company does not undertake the responsibility to update or revise such forward-looking statements, except as required by law.

Non-GAAP Financial Measures

As discussed on page 39 of the company’s Annual Report on Form 10-K for the year ended December 31, 2025, the company uses non-GAAP financial measures as important measures of its operating performance, including operating income, operating income before interest expense and income taxes, operating income per diluted 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 2025 Annual Report on pages 61-64.

Operating income and operating income per diluted share are non-GAAP measures. They are defined as net income 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, as they are, to a certain extent, determined by interest rates, financial markets and the timing of sales. Operating income 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 is the sum of the segment income 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” is the segment income before both interest expense and income taxes. The company also uses “operating income per diluted 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 and operating income 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 attributable to the core operations of the business. Income from continuing operations is the most directly comparable GAAP measure for operating income (and operating income before income taxes) and measures of operating income that exclude the effects of catastrophe losses and/or prior-year reserve development. These non-GAAP measures should not be misconstrued as substitutes for income from continuing operations or net income determined in accordance with GAAP. A reconciliation of operating income to income from continuing operations and net income for the relevant periods is included on page 9 of this news release and in the Financial Supplement.

Operating return on average equity (ROE) is a non-GAAP measure. See end note (6) for a detailed explanation of how this measure is calculated. Operating ROE is based on non-GAAP operating income. 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 and shareholders’ equity of the entire company and without adjustments.

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 a non-GAAP measure and 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.

The company may provide measures of operating income 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, fires, drought, 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.

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.

Combined ratio, excluding catastrophes, and current accident year combined ratio, excluding catastrophes, are non-GAAP measures. These and other non-GAAP measures are used throughout this document. See the disclosure on the use of this and other non-GAAP measures under the headings “Forward-Looking Statements" and "Non-GAAP Financial Measures.” The combined ratio (which includes catastrophe losses and prior-year loss reserve development) is the most directly comparable GAAP measure. A reconciliation of the GAAP combined ratio to the combined ratio, excluding catastrophes, and to the current accident year combined ratio, excluding catastrophes, is shown below.

Renewal price changes in Core Commercial and Specialty represent the average change in premium on renewed policies caused by the estimated net effect of base rate changes, discretionary pricing, specific inflationary changes or changes in policy level exposure or insured risks. Rate increases in Core Commercial and Specialty represent the average change in premium on renewed policies caused by the base rate changes, discretionary pricing, and inflation, excluding the impact of changes in policy level exposure or insured risks. Renewal price change in Personal Lines represents the average change in premium on policies charged at renewal caused by the net effects of filed rate, inflation adjustments or other changes in policy level exposure or insured risks, regardless of whether or not the policies are retained for the duration of their contractual terms. Rate change in Personal Lines is the estimated cumulative premium effect of approved rate actions applied to policies at renewal, regardless of whether or not policies are actually renewed. Accordingly, rate changes do not represent actual increases or decreases realized by the company. Personal Lines rate changes do not include inflation or changes in policy level exposure or insured risks.

Current accident year loss and LAE ratio, excluding catastrophe losses, is a non-GAAP measure, which is equal to the loss and LAE ratio (loss ratio), excluding prior-year reserve development and catastrophe losses. The loss ratio (which includes losses, LAE, catastrophe losses and prior-year loss reserve development) is the most directly comparable GAAP measure. The following is a reconciliation of the GAAP loss ratio to the current accident year loss ratio, excluding catastrophe losses.

Operating income and operating income per diluted share are non-GAAP measures. Operating income before income taxes, as referenced in the results of the reporting segments, is defined as, with respect to such segment, operating income before interest expense and income taxes. The reconciliation of operating income and operating income per diluted share to the closest GAAP measures, income from continuing operations and income from continuing operations per diluted share, respectively, and to net income and net income per diluted share, respectively, is provided on the preceding pages of this news release.

Operating return on average equity (operating ROE) is a non-GAAP measure. Operating ROE is calculated by dividing annualized operating income after tax for the applicable period (see under the heading in this news release “Non-GAAP Financial Measures” and end note (5)), by average shareholders’ equity, excluding unrealized appreciation (depreciation) on fixed maturity investments, net of tax, for the period presented. Total shareholders’ equity, excluding net unrealized appreciation (depreciation) on fixed maturity investments, net of tax, is also a non-GAAP measure. Total shareholders’ equity is the most directly comparable GAAP measure and is reconciled in the following table. For the calculation of operating ROE, the average of beginning and ending shareholders’ equity, excluding net unrealized appreciation (depreciation) on fixed maturity investments, net of tax, is used for the period as shown and reconciled in the following table.

THE HANOVER INSURANCE GROUP

Non-GAAP Financial Measures

The Hanover uses non-GAAP financial measures as important measures of the Company’s operating performance, which we believe provide investors with additional information regarding management’s evaluation of our results of operations and financial performance. The Company’s non-GAAP measures include operating income before interest expense and income taxes, total operating income after income taxes, total operating income after income taxes per diluted share, total book value per share, total book value per share excluding net unrealized gains and losses related to fixed maturity investments and market risk, net of tax, tangible book value per share and measures of operating income and combined ratios excluding catastrophe losses (catastrophe losses as discussed here and in all other measures include catastrophe loss development) and reserve development.

Operating income before interest expense and income taxes is net income, excluding interest expense on debt, income taxes and net realized and unrealized investment gains and losses, which includes changes in the fair value of equity securities still held because fluctuations in these gains and losses are determined by interest rates, financial markets and the timing of sales. Operating income before interest expense and income taxes also excludes net gains and losses on disposals of businesses, discontinued operations, restructuring costs, the cumulative effect of accounting changes and certain other items. Operating income before interest expense and income taxes is the sum of the operating income (loss) from: Core Commercial, Specialty, Personal Lines, and Other. After-tax operating income earnings per diluted share (sometimes referred to as “after-tax operating income per share”) is also a non-GAAP measure. It is defined as net income excluding the after-tax impact of net realized and unrealized investment gains (losses), as well as results from discontinued operations and other non-operating items for a period divided by the average number of diluted shares of common stock. The Hanover believes that measures of operating income before interest expense and income taxes provide investors with a valuable measure of the performance of the Company’s ongoing businesses because they highlight net income attributable to the core operations of the business.

Book value per share is total shareholders’ equity divided by the number of common shares outstanding. Book value per share excluding net unrealized gains and losses related to fixed maturity investments, net of tax, is total shareholders’ equity excluding the after-tax effect of unrealized investment gains and losses on fixed maturities and market risk divided by the number of common shares outstanding. Tangible book value per share is total shareholders’ equity, excluding goodwill and intangible assets, divided by the number of common shares outstanding.

The Hanover also provides measures of operating results and loss ratios that exclude the effects of catastrophe losses. A catastrophe is a severe loss, resulting from natural or manmade events. Catastrophes can be caused by various natural events including, among others, hurricanes, tornadoes and other windstorms, hail, flood, earthquakes, severe winter weather and other convective storms, fire, and explosions. Catastrophes can be caused by various manmade events including, among others, fire, explosions, riots, and terrorism. Each catastrophe has unique characteristics. Catastrophes are not predictable as to timing or loss amount in advance. The Hanover believes that providing certain financial metrics and trends excluding the effects of catastrophes is meaningful for investors to understand the variability of periodic earnings and loss ratios.

Prior year reserve development, which can be favorable or unfavorable, represents changes in our estimate of the costs to pay claims from prior years. We believe that a discussion of operating income excluding prior year reserve development is helpful to investors since it provides insight into both our estimate of current year accident results and changes to prior-year reserve estimates.

Operating income before and after interest expense and income taxes and measures of operating income that exclude the effects of catastrophe losses or reserve development should not be construed as substitutes for income before income taxes or income from continuing operations and operating income should not be construed as a substitute for net income determined in accordance with GAAP. A reconciliation of income from continuing operations to operating income before interest expense and income taxes and income from continuing operations per diluted share to operating income after taxes per diluted share for the three and six months ended June 30, 2026 and 2025 is set forth on page 20 of this document. The presentation of loss ratios calculated excluding the effects of reserve development and/or catastrophe losses should not be construed as a substitute for loss ratios determined in accordance with GAAP.

Additional reconciliations are provided in the press release relating to the current period(s) financial results, which is available on the Company’s website, www.hanover.com.
