Special Note Regarding Forward-Looking Statements

This Quarterly Report on Form 10-Q (“Quarterly Report”) includes “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”) and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). All statements other than statements of historical facts included in this Quarterly Report, including, without limitation, statements regarding our future financial position, business strategy, budgets, projected costs, savings and plans and objectives of management for future operations, are forward-looking statements. In addition, forward-looking statements generally can be identified by the use of forward-looking terminology such as “may,” “will,” “expect,” “intend,” “estimate,” “plan,” “anticipate,” “believe” or “continue” or the negative thereof or variations thereon or similar terminology. Although we believe that the expectations reflected in such forward-looking statements are reasonable, we can give no assurance that such expectations will prove to have been correct.

You should read the “Special Note Regarding Forward-Looking Statements” and “Risk Factors” sections of our Annual Report on Form 10-K for the year ended December 31, 2024 and filed with the Securities and Exchange Commission (“SEC”), on February 27, 2025, for a discussion of important factors that could cause actual results to differ materially from the results described in or implied by the forward-looking statements contained in this report. There may be other factors not presently known to us or which we currently consider to be immaterial that may cause our actual results to differ materially from the forward-looking statements.

All forward-looking statements attributable to us or persons acting on our behalf apply only as of the date of this Quarterly Report and are expressly qualified in their entirety by the cautionary statements included in this Quarterly Report and in the Annual Report on Form 10-K for the year ended December 31, 2024. We undertake no obligation to publicly update or revise any forward-looking statements to reflect events or circumstances after the date made or to reflect the occurrence of unanticipated events.
