Forward-Looking Statements

This communication contains forward-looking statements. Forward-looking statements are generally identified by the words “expects”, “anticipates”, “believes”, “intends”, “estimates”, “plans”, “will be” and similar expressions. These forward-looking statements include, without limitation, statements related to the anticipated consummation of the acquisition of the Company and the timing and benefits thereof, and other statements that are not historical facts. These forward-looking statements are based on Parent’s and the Company’s current expectations and inherently involve significant risks and uncertainties. Actual results and the timing of events could differ materially from those anticipated in such forward-looking statements as a result of these risks and uncertainties, which include, without limitation, risks related to the parties’ ability to complete the transaction on the proposed terms and schedule; whether the tender offer conditions will be satisfied; whether sufficient stockholders of the Company tender their shares in the transaction; the outcome of legal proceedings that may be instituted against the Company and/or others relating to the transaction; the failure (or delay) to receive the required regulatory approvals relating to the transaction; the possibility that competing offers will be made; and other risks related to the Company’s business detailed from time-to-time under the caption “Risk Factors” and elsewhere in the Company’s filings and reports filed with the U.S. Securities and Exchange Commission (the “SEC”), including the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 and subsequent quarterly and current reports filed with the SEC. The risks and uncertainties may be amplified by the Russian invasion of Ukraine and the ongoing COVID-19 pandemic, which has caused significant economic uncertainty. The extent to which these factors impact the Company’s business, operations, and financial results, including the duration and magnitude of such effects, will depend on numerous factors, which are unpredictable, including, but not limited to, the duration of the conflict in Ukraine, the duration and spread of the COVID-19 outbreak, the spread of any new variants of COVID-19, the actions to contain the virus or treat its impact, and how quickly and to what extent normal economic and operating conditions can resume. The Company undertakes no duty or obligation to update any forward-looking statements contained in this communication as a result of new information, future events or changes in their expectations, except as required by law.
