SUPPLEMENTAL INFORMATION*

November 1, 2023

  • All information provided in these slides is qualified in its entirety by reference to the Company's filings with the
    Securities and Exchange Commission (SEC), which are available on both the Company's and the SEC's websites.

Statement Regarding Safe Harbor for Forward-Looking Statements

Investors are cautioned that all statements herein that relate to the future involve risks and uncertainties, and are based on assumptions that the Company believes in good faith are reasonable but which may be materially different from actual results. These statements, which are forward-looking statements under the Private Securities Litigation Reform Act of 1995, provide the investor with the Company's expectations or forecasts of future events. You can identify these statements by the fact that they do not relate only to historical or current facts. They may use words such as "guidance", "anticipate", "may", "expect", "should", "believe", "will", and other words of similar meaning in connection with future events or future operating or financial performance. Any or all of the Company's forward-looking statements here and in other publications may turn out to be wrong.

Non-GAAP Financial Measures

This material contains financial measures that have not been prepared in accordance with generally accepted accounting principles in the United States (GAAP). Reconciliations of non- GAAP financial measures to the closest GAAP measures are included in the accompanying Appendix. Management believes these non-GAAP measures are commonly used financial measures for investors to evaluate the Company's operating performance and, when read in conjunction with the Company's consolidated financial statements, present a useful tool to evaluate the Company's ongoing operations, performance from period to period and anticipated performance. In addition, these are some of the factors the Company uses in internal evaluations of the overall performance of its businesses. Management acknowledges that there are many items that impact reported results and the adjustments reflected in these non-GAAP measures are not intended to present all items that may have impacted these results. In addition, these non-GAAP measures are not necessarily comparable to similarly titled measures used by other companies.

Results and Trends

Results and trends described in this Supplemental Information may not necessarily be indicative of the Company's future performance.
