provisions in charter documents and Delaware law that delay or prevent our acquisition; the timing, receipt and terms and conditions of any required governmental and regulatory approvals of the proposed transaction that could cause the parties to terminate the merger agreement; the occurrence of any event, change or other circumstances that could give rise to the termination of the merger agreement entered into pursuant to the proposed transaction; the possibility that our stockholders may not approve the proposed transaction; the risk that the parties to the merger agreement may not be able to satisfy the conditions to the proposed transaction in a timely manner or at all; risks related to disruption of management time from ongoing business operations due to the proposed transaction; the risk that any announcements relating to the proposed transaction could have adverse effects on the market price of our common stock; the risk of any unexpected costs or expenses resulting from the proposed transaction; the risk of any litigation relating to the proposed transaction; the risk that the proposed transaction and its announcement could have an adverse effect on the ability of the company to retain customers and retain and hire key personnel and maintain relationships with customers, suppliers, employees, stockholders and other business relationships and on its operating results and business generally; and the risk the pending proposed transaction could distract management of the company.  The company directs readers to its Form 10-K for the year ended December 31, 2022 and the other documents it files with the SEC for other risks associated with the company’s future performance.  These documents contain and identify important factors that could cause our actual results to differ materially from those contained in our forward-looking statements.  All information in this communication is as of the date above.  The company undertakes no duty to update any forward-looking statement to conform the statement to actual results or changes in the company’s expectations.
