Fourth Quarter 2022 Investor Presentation

INVESTOR PRESENTATION

February 2023

Forward-Looking Statements

In this presentation, the Company and its management discuss and make statements based on currently available information regarding their intentions, beliefs, current expectations, and projections of, among other things, the Company's future performance, including the effects of the Coronavirus (COVID-19) pandemic, business growth, retention rates, loss costs, claim trends and the impact of key business initiatives, future technologies and planned investments. Certain of these statements may constitute "forward-looking" statements as that term is defined in the Private Securities Litigation Reform Act of 1995. Forward-looking statements can be identified by the fact that they do not relate strictly to historical or current facts and are often identified by 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 and their negatives. The Company and its management caution investors that such forward-looking statements are not guarantees of future performance. Risks and uncertainties are inherent in the Company's future performance. Factors that could cause the Company's actual results to differ materially from those indicated by such forward-looking statements include, among other things, those discussed or identified from time to time in the Company's public filings with the U.S. Securities and Exchange Commission (the SEC), including the risks detailed in the Company's Quarterly Reports on Form 10-Q and the Company's Annual Reports on Form 10-K. Except as required by applicable securities laws, the Company undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise.
