Cautionary Statement Regarding Forward-Looking Statements

This Proxy Statement may contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements provide current expectations of future events based on certain assumptions and include any statement that does not directly relate to any historical fact. Forward-looking statements generally can be identified by words such as “expects,” “intends,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” “projects,” “should,” “may,” “will,” “will continue,” “can,” “could,” or the negative of these words, variations of these words, and comparable terminology, in each case, intended to refer to future events or circumstances. However, the absence of these words or similar expressions does not mean that a statement is not forward-looking. Forward-looking statements are subject to various uncertainties and risks that could cause our actual results to differ materially from historical experience and our present expectations or projections. These risks and uncertainties include, but are not limited to, those described under the captions “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the Company’s Annual Report on Form 10-K for Fiscal Year 2026 and in our Quarterly Reports on Form 10-Q filed with the SEC. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof and are based upon information available to us at this time. The Company undertakes no obligation to update forward-looking statements to reflect events or circumstances after the date they were made, unless required by applicable law.
