HANOVER INSURANCE GROUP, INC.

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations is intended to assist readers in understanding the interim consolidated results of operations and financial condition of The Hanover Insurance Group, Inc. and its subsidiaries (“THG”). Consolidated results of operations and financial condition are prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”). This discussion should be read in conjunction with the interim consolidated financial statements and related footnotes included elsewhere in this Quarterly Report on Form 10-Q and Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in our Annual Report on Form 10-K filed with the Securities and Exchange Commission (the “SEC”) on February 20, 2026.

Results of operations include the accounts of The Hanover Insurance Company (“Hanover Insurance”) and Citizens Insurance Company of America (“Citizens”), our principal property and casualty companies, and certain other insurance and non-insurance subsidiaries.

The following discussion contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements may address, among other things, our growth strategy; expected developments in our business, including losses and loss reserves; the impact of our routine reserve reviews; our expectations regarding our investment activities or results; our proposed actions in response to trends in our business; as well as our expectations, intentions and other statements that are not historical facts. Words such as: “believes,” “anticipates,” “expects,” “may,” “projections,” “outlook,” “intends,” “should,” “could,” “will,” “plan,” “goal,” “guidance,” “likely,” “on track to,” “potential,” “continue,” “targeted,” “designed,” “positioned,” and similar expressions are intended to identify forward-looking statements. Forward-looking statements by their nature address matters that are, to different degrees, uncertain. We caution readers that accuracy with respect to forward-looking projections is difficult and subject to risks and uncertainties. Those risks and uncertainties, in some cases, have affected, and in the future could affect, our actual results and could cause our actual results to differ materially from historical results and from those expressed in any of our forward-looking statements. In addition to some of the factors in the discussion below, other important factors that could cause actual results to differ materially from those contained in forward-looking statements, are set forth in “Risk Factors” in Part II – Item 1A of this Quarterly Report on Form 10-Q and in Part I – Item 1A of our 2025 Annual Report on Form 10-K.
