Note Regarding Forward-Looking Statements

The statements contained in this Form 8-K that are not purely historical may be “forward-looking statements” as defined in the Private Securities Litigation Reform Act of 1995.

Words such as expects, anticipates, intends, plans, believes, will, could, should, estimates, may, targets, strategies, intends to, projects, forecasts, guidance, likely, and usually, or variations of such words and other similar expressions identify forward-looking statements, which are based on current expectations and assumptions.

These forward-looking statements are based on the Company’s current expectations and beliefs concerning future developments and their potential effects on the Company. While the Company’s expectations, beliefs and estimates are expressed in good faith and the Company believes there is a reasonable basis for them, there can be no assurance that future developments affecting the Company will be those that we have anticipated. These forward-looking statements involve a number of risks, uncertainties (some of which are beyond the control of the Company) or other assumptions that may cause actual results or performance to be materially different from those expressed or implied by such forward-looking statements. These risks and uncertainties include, but are not limited to: unfavorable outcomes of existing or future litigation or dispute resolution proceedings; risks and other uncertainties associated with assumptions and estimates used to prepare financial statements; and other risks and uncertainties discussed under the heading “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2021 filed on February 16, 2022, under the heading “Risk Factors” in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2022 filed on April 28, 2022, under the heading “Risk Factors” in our Quarterly Report on Form 10-Q for the quarter ended June 30, 2022 filed on July 27, 2022, under the heading “Risk Factors” in our Quarterly Report on Form 10-Q for the quarter ended September 30, 2022 filed on October 26, 2022, and in other reports that we file with the Securities and Exchange Commission from time to time. The Company undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as may be required under applicable laws.

The forward looking statements in this Form 8-K represent our view as of February 15, 2023.
