Forward-Looking Statements

This Proxy Statement includes “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical or current facts made in this document are forward-looking. In some cases, you can identify these forward-looking statements by the use of words such as “anticipate”, “believe”, “can”, “continue”, “could”, “estimate”, “expect”, “forecast”, “goal”, “intend”, “may”, “might”, “objective”, “outlook”, “plan”, “potential”, “predict”, “projection”, “seek”, “should”, “target”, “trend”, “will”, “would” or the negative version of these words or other comparable words.

We have based our forward-looking statements on beliefs and assumptions based on information available to us at the time the statements are made. We caution you that assumptions, beliefs, expectations, intentions and projections about future events may, and often do, vary materially from actual results. Therefore, we cannot assure you that actual results will not differ materially from those expressed or implied by our forward-looking statements. Certain risks and uncertainties that could cause our actual results to differ significantly from management’s expectations are described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025 (our “2025 10-K”). Should one or more of these risks or uncertainties materialize, or should any of our assumptions prove incorrect, our actual results may vary in material respects from those projected in these forward-looking statements. Factors or events that could cause our actual results to differ may emerge from time to time, and it is not possible for us to predict all of them. Our forward-looking statements do not reflect the potential impact of any future acquisitions, mergers, dispositions, joint ventures, investments, or other strategic transactions we may make. Each forward-looking statement speaks only as of the date of the particular statement, and we undertake no obligation to update or revise any forward-looking statements whether as a result of new information, future developments or otherwise, except as required by law. You should not place undue reliance on our forward-looking statements.

Website references throughout this document are provided for convenience only, and the content on the referenced websites is not incorporated by reference into this document.
