There can be no assurance that future developments will be those that have been anticipated. These forward-looking statements involve a number of risks, uncertainties or other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements including: risks related to the Company’s businesses and strategies; the ability to complete the proposed business combination due to the failure to obtain approval from MCAF’s stockholders or satisfy other closing conditions in the definitive merger agreement; the amount of any redemptions by existing holders of MCAF’s common stock; the ability to recognize the anticipated benefits of the business combination; in the final prospectus of Mountain Crest Acquisition Corp. IV for its initial public offering dated June 29, 2021; and in Mountain Crest Acquisition Corp. IV’s other filings with the SEC.
