Item 4.02 Non-Reliance on Previously Issued Financial Statements or a Related Audit Report or Completed Interim Review.

In connection with the preparation of Growth Capital Acquisition Corp.’s (the “Company”) financial statements as of September 30, 2021, the Company’s management, in consultation with its advisors, identified an error made in certain of its previously issued financial statements, arising from the manner in which, as of the closing of the Company’s initial public offering, the Company valued its Class A common stock subject to possible redemption. The Company previously determined the value of such Class A common stock to be equal to the redemption value of such shares of Class A common stock, after taking into consideration the terms of the Company’s Amended and Restated Certificate of Incorporation, under which a redemption cannot result in net tangible assets being less than $5,000,001. Management has now determined, that the shares of Class A common stock underlying the units issued during the initial public offering can be redeemed or become redeemable subject to the occurrence of future events considered to be outside the Company’s control. Therefore, management has concluded that the redemption value of its shares of Class A common stock subject to possible redemption should reflect the possible redemption of all shares of Class A common stock. By reason of this determination, management has determined that its previously issued financial statements contained a reclassification error related to temporary equity and permanent equity. As a result, management has determined to restate the initial carrying value of the shares of Class A common stock subject to possible redemption, with the offset recorded to additional paid-in capital (to the extent available), accumulated deficit and shares of Class A common stock.

On November 22, 2021, the audit committee of the board of directors of the Company (the “Audit Committee”) determined, that the Company’s (i) audited balance sheet as of February 2, 2021 filed as Exhibit 99.1 to the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on February 4, 2021, (ii) audited financial statements as of March 31, 2021 contained in the Company’s Annual Report on Form 10-K filed with the SEC on July 19, 2021, and (iii) unaudited financial statements as of June 30, 2021 contained in the Company’s Quarterly Report on Form 10-Q filed with the SEC on August 19, 2021, should no longer be relied upon due to the reclassification described above. The Company has reflected this reclassification in its Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2021, filed with SEC on November 23, 2021 (the “November 2021 Form 10-Q”) and in the Company’s forthcoming amended Annual Report on Form 10-K for the period ended March 31, 2021. The Company does not expect the changes described above to have any impact on its cash position or the balance held in 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 during all periods noted above. The Company’s remediation plan with respect to such material weakness is described in more detail in the November 2021 Form 10-Q.

The Company’s management and the Audit Committee have discussed the matters disclosed in this Current Report on Form 8-K pursuant to this Item 4.02 with Marcum LLP, the Company’s independent registered public accounting firm.
