Securities registered pursuant to Section 12(b) of the Act:

Indicate by check mark whether the registrant is an emerging growth company as defined in Rule 405 of the Securities Act of 1933 (§230.405 of this chapter) or Rule 12b-2 of the Securities Exchange Act of 1934 (§240.12b-2 of this chapter).

(a) In light of recent comment letters issued by the U.S. Securities and Exchange Commission (the “SEC”), the management of MCAP Acquisition Corporation (the “Company”) has re-evaluated the Company’s application of ASC 480-10-S99-3A to its accounting classification of the redeemable shares of Class A common stock, par value $0.0001 per share (the “Public Shares”), issued as part of the units sold in the Company’s initial public offering (the “IPO”) on March 2, 2021. Historically, a portion of the Public Shares was classified as permanent equity to maintain net tangible assets greater than $5,000,000 on the basis that the Company will consummate its initial business combination only if the Company has net tangible assets of at least $5,000,001. Pursuant to such re-evaluation, the Company’s management has determined that the Public Shares include certain provisions that require classification of the Public Shares as temporary equity regardless of the minimum net tangible assets required to complete the Company’s initial business combination.

Therefore, on November 12, 2021, the Company’s management and the audit committee of the Company’s board of directors (the “Audit Committee”) concluded that the Company’s previously issued (i) audited balance sheet as of March 2, 2021, as previously restated in the Company’s Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2021, filed with the SEC on May 26, 2021 (the “Q1 Form 10-Q”), (ii) unaudited interim financial statements included in the Q1 Form 10-Q and (iii) unaudited interim financial statements included in the Company’s Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2021, filed with the SEC on August 5, 2021 (collectively, the “Affected Periods”), should be restated to report all Public Shares as temporary equity and should no longer be relied upon. As such, the Company has restated its financial statements for the Affected Periods in the Company’s Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2021, filed with the SEC on November 16, 2021 (the “Q3 Form 10-Q”), as described therein.

The Company does not expect any of the above changes will have any impact on its cash position and cash held in the trust account established in connection with the IPO (the “Trust Account”).

The Company’s management has concluded that in light of the classification error described above, a material weakness exists in the Company’s internal control over financial reporting and that the Company’s disclosure controls and procedures were not effective. The Company’s remediation plan with respect to such material weakness is described in more detail in the Q3 Form 10-Q.

The Company’s Audit Committee has discussed the matters disclosed in this Item 4.02(a) with the Company’s independent registered public accounting firm, Marcum LLP.
