IMPORTANT NOTICES

Important Notice Regarding Forward-Looking Statements

This Current Report on Form 8-K contains certain “forward-looking statements” within the meaning of the Securities Act of 1933 and the Securities Exchange Act of 1934, both as amended. Statements that are not historical facts, including statements about the pending transactions described above, and the parties’ perspectives and expectations, are forward-looking statements. Such statements include, but are not limited to, statements regarding the proposed transaction, including the anticipated initial enterprise value and post-closing equity value, the benefits of the proposed transaction, integration plans, expected synergies and revenue opportunities, anticipated future financial and operating performance and results, including estimates for growth, the expected management and governance of the combined company, and the expected timing of the transactions. The words “expect,” “believe,” “estimate,” “intend,” “plan” and similar expressions indicate forward-looking statements. These forward-looking statements are not guarantees of future performance and are subject to various risks and uncertainties, assumptions (including assumptions about general economic, market, industry and operational factors), known or unknown, which could cause the actual results to vary materially from those indicated or anticipated.

The forward-looking statements are based on the current expectations of the management of MCAF and the Company, as applicable, and are inherently subject to uncertainties and changes in circumstances and their potential effects and speak only as of the date of such statement. 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. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those indicated or anticipated by such forward-looking statements. Accordingly, you are cautioned not to place undue reliance on these forward-looking statements. Forward-looking statements relate only to the date they were made, and MCAF, the Company and their subsidiaries undertake no obligation to update forward-looking statements to reflect events or circumstances after the date they were made except as required by law or applicable regulation.
