Cautionary Note Regarding Forward-Looking Statements

This report, including Exhibit 99.1 furnished herewith, includes certain statements that may constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act. All statements other than statements of historical fact are forward-looking statements for purposes of federal and state securities laws. These forward-looking statements involve uncertainties that could significantly affect the Company’s financial or operating results. These forward-looking statements may be identified by terms such as “anticipate,” “believe,” “continue,” “foresee,” “expect,” “intend,” “plan,” “may,” “will,” “would,” “could,” and “should,” and the negative of these terms or other similar expressions. Forward-looking statements are based on current beliefs and assumptions that are subject to risks and uncertainties and are not guarantees of future performance. Forward-looking statements in this report include, among other things, statements regarding the business plan, business strategy and operations of the Company in the future. In addition, all statements that address operating performance and future performance, events or developments that are expected or anticipated to occur in the future are forward looking statements. Forward-looking statements are subject to a number of risks, uncertainties and assumptions. Matters and factors that could cause actual results to differ materially from those expressed or implied in such forward-looking statements include but are not limited to the matters and factors described under the heading “Risk Factors” of the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, as may be amended from time to time, its subsequently filed Quarterly Reports on Form 10-Q and its other filings with the Securities and Exchange Commission. Consequently, all of the forward-looking statements made in this report are qualified by the information contained under this caption. No assurance can be given that these are all of the factors that could cause actual results to vary materially from the forward-looking statements in this report. You should not put undue reliance on forward-looking statements. No assurances can be given that any of the events anticipated by the forward-looking statements will transpire or occur, or if any of them do occur, the actual results, performance, or achievements of the Company could differ materially from the results expressed in, or implied by, any forward-looking statements. All forward-looking statements speak only as of the date of this report and, unless otherwise required by U.S. federal securities law, the Company does not assume any duty to update or revise any forward-looking statements included in this report, whether as a result of new information, the occurrence of future events, uncertainties or otherwise, after the date of this report.
