This proxy statement contains forward-looking statements about future events and circumstances. Generally speaking, any statement not based upon historical fact is a forward-looking statement. Forward-looking statements can also be identified by the use of forward-looking or conditional words such as “could,” “should,” “can,” “continue,” “estimate,” “forecast,” “intend,” “look,” “may,” “will,” “expect,” “believe,” “anticipate,” “plan,” “remain,” “confident” and “commit” or similar expressions. In particular, statements regarding our plans, strategies, prospects and expectations regarding our business and industry are forward-looking statements. They reflect our expectations, are not guarantees of performance and speak only as of the date of this proxy statement. Except as required by law, we do not undertake to update such forward-looking statements. You should not rely unduly on forward-looking statements. Our business results are subject to a variety of risks, including those that are described in our annual report on Form 10-K for the year ended December 31, 2024 and elsewhere in our filings with the SEC. If any of these considerations or risks materialize or intensify, our expectations (or underlying assumptions) may change and our performance may be adversely affected.
