As previously reported, pursuant to the stockholders’ approval at the special meeting of stockholders held on December 20, 2022 (the “Special Meeting”), Mountain Crest Acquisition Corp. V, a Delaware corporation (“SPAC”), (1) filed an amendment to its Amended and Restated Certificate of Incorporation with the Delaware Secretary of State on December 20, 2022, giving SPAC the right to extend the date by which it has to complete a business combination (the “Business Combination Period”) from February 16, 2023 to May 16, 2023 and (2) entered into an amendment to the Investment Management Trust Agreement, dated as of November 12, 2021, with Continental Stock Transfer & Trust Company, on December 20, 2022 (the “Trust Amendment”). The Trust Amendment provides that SPAC may extend the Business Combination Period by depositing $300,000 into the trust account. On February 15, 2023, SPAC extended the Business Combination Period from February 16, 2023 to May 16, 2023 by depositing $300,000 into the trust account.

The $300,000 was loaned to SPAC, by Mountain Crest Global Holdings LLC, a Delaware limited liability company and SPAC’s sponsor (the “Sponsor”). On February 15, 2023, SPAC issued a non-interest bearing, unsecured promissory note in the aggregate principal amount of $300,000 (the “Note”) to the Sponsor. Pursuant to the Note, the Sponsor loaned SPAC an aggregate amount of $300,000 that is due and payable upon SPAC’s consummation of an initial business combination with a target business. The Note will either be paid upon consummation of SPAC’s initial business combination, or, at the Sponsor’s discretion, converted upon consummation of the SPAC’s business combination into private units at a price of $10.00 per unit. The loan will be forgiven, except to the extent of any funds held outside of the trust account, by the Sponsor or its affiliates if SPAC is unable to consummate an initial business combination during the Business Combination Period.

The foregoing description of the Note is qualified in its entirety by reference to the full text of the Note, a copy of which is filed with this Current Report on Form 8-K as Exhibit 10.1 and is incorporated herein by reference.

Important Notice Regarding Forward-Looking Statements

This Current Report on Form 8-K contains “forward-looking statements” within the meaning of the “safe harbor” provisions of the United States Private Securities Litigation Reform Act of 1995. SPAC’s and the Company’s actual results may differ from their expectations, estimates, and projections and, consequently, you should not rely on these forward-looking statements as predictions of future events. Words such as “expect,” “estimate,” “project,” “budget,” “forecast,” “anticipate,” “intend,” “plan,” “may,” “will,” “could,” “should,” “believes,” “predicts,” “potential,” “continue,” and similar expressions (or the negative versions of such words or expressions) are intended to identify such forward-looking statements. These forward-looking statements include, without limitation, SPAC’s and the Company’s expectations with respect to future performance and anticipated financial impacts of the proposed business combination, the satisfaction of the closing conditions to the proposed business combination, and the timing of the completion of the proposed business combination.

These forward-looking statements involve significant risks and uncertainties that could cause the actual results to differ materially from those discussed in the forward-looking statements. Most of these factors are outside SPAC’s and the Company’s control and are difficult to predict. Factors that may cause such differences include, but are not limited to: (1) the occurrence of any event, change, or other circumstances that could give rise to the termination of the Business Combination Agreement; (2) the outcome of any legal proceedings that may be instituted against SPAC and the Company following the announcement of the Business Combination Agreement and the transactions contemplated therein; (3) the inability to complete the proposed business combination, including due to failure to obtain approval of the stockholders of SPAC and the Company, certain regulatory approvals, or satisfy other conditions to closing in the Business Combination Agreement; (4) the occurrence of any event, change, or other circumstance that could give rise to the termination of the Business Combination Agreement or could otherwise cause the transaction to fail to close; (5) the impact of the COVID-19 pandemic on the Company’s business and/or the ability of the parties to complete the proposed business combination; (6) the inability to obtain the listing of Holdco’s ordinary shares on Nasdaq following the proposed business combination; (7) the risk that the proposed business combination disrupts current plans and operations as a result of the announcement and consummation of the proposed business combination; (8) the ability to recognize the anticipated benefits of the proposed business combination, which may be affected by, among other things, competition, the ability of the Company to grow and manage growth profitably, and retain its key employees; (9) costs related to the proposed business combination; (10) changes in applicable laws or regulations; (11) the possibility that SPAC or the Company may be adversely affected by other economic, business, and/or competitive factors; (12) risks relating to the uncertainty of the projected financial information with respect to the Company; (13) risks related to the organic and inorganic growth of the Company’s business and the timing of expected business milestones; (14) the amount of redemption requests made by SPAC’s stockholders; and (15) other risks and uncertainties indicated from time to time in the final prospectus of SPAC for its initial public offering and the Registration Statement relating to the proposed business combination, including those under “Risk Factors” therein, and in SPAC’s other filings with the SEC. SPAC cautions that the foregoing list of factors is not exclusive. SPAC and the Company caution readers not to place undue reliance upon any forward-looking statements, which speak only as of the date made. SPAC and the Company do not undertake or accept any obligation or undertaking to release publicly any updates or revisions to any forward-looking statements to reflect any change in their expectations or any change in events, conditions, or circumstances on which any such statement is based.
