Forward-Looking Statements

~~SIGNATURES~~This document contains “forward-looking statements” within the meaning of the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995. Forward-looking statements also may be included in other publicly available documents issued by the Company and in oral statements made by our officers and representatives from time to time. These forward-looking statements are intended to provide management’s current expectations or plans for our future operating and financial performance, based on assumptions currently believed to be valid and information currently available to management. They can be identified by the use of words such as “may,” “might,” “anticipate,” “plan,” “believe,” “potential,” “intend,” “expect,” “strategy,” “will” and other words of similar meaning in connection with a discussion of future operating or financial performance. Examples of forward-looking statements include, among others, statements relating to future sales, earnings, cash flows, results of operations, uses of cash and other measures of financial performance. Because forward-looking statements relate to the future, they are subject to inherent risks, uncertainties and other factors that may cause the Company’s actual results and financial condition to differ materially from those expressed or implied in the forward-looking statements. Such risks and uncertainties include, but are not limited to, the following risks: (i) the occurrence of any event, change or other circumstances that could give rise to the termination of the Merger Agreement; (ii) the risk that the Company’s stockholders may not approve the Transaction; (iii) inability to complete the Transaction because, among other reasons, conditions to the closing of the Transaction may not be satisfied or waived; (iv) uncertainty as to the timing of completion of the Transaction; (v) potential adverse effects or changes to relationships with customers, employees, suppliers or other parties resulting from the announcement or completion of the Transaction; (vi) potential litigation relating to the Transaction that could be instituted against the Company, Parent or their respective directors and officers, including the effects of any outcomes related thereto; or (vii) possible disruptions from the Transaction that could harm the Company’s or Parent’s business, including current plans and operations. Further information regarding the important factors that could cause actual results to differ from projected results can be found in the Company’s reports filed or that may be filed with the Securities and Exchange Commission (the “SEC”), including our Annual Report on Form 10-K for the fiscal year ended March 31, 2024 and our Quarterly Reports on Form 10-Q for the fiscal quarters ended June 30, 2024, September 30, 2024 and December 31, 2024.
