In addition to historical information, this proxy statement contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). These statements include, among other things, our strategies and financial performance; our development of new and existing products and technologies; and other statements that are not historical fact. These statements may contain words such as “anticipate,” “believe,” “estimate,” “expect,” “future,” “intend,” “may,” “opportunity,” “plan,” “project,” “should,” “strategy,” “will,” “will be,” “will continue,” “will likely result,” “would” and similar expressions.

These forward-looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially from those reflected in the forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those discussed in Part II, Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and in particular, the risks discussed in Part I, Item 1A “Risk Factors” of our Annual Report on Form 10-K for the year ended December 31, 2024, which was filed with the Securities and Exchange Commission on February 28, 2025.

We undertake no obligation to revise or update these forward-looking statements. Given these risks and uncertainties, readers are cautioned not to place undue reliance on such forward-looking statements.

Unless otherwise expressly stated or context requires otherwise, information in this proxy statement is as of April 8, 2025.
