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 the financial statements of Roth CH Acquisition III Co. (the “Company”) as of September 30, 2021, the Company’s management identified errors made in its historical financial statements where, at the closing of the Company’s Initial Public Offering on March 5, 2021 (the “IPO”), the Company improperly valued its common stock, par value $0.0001 per share (“common stock”), subject to possible redemption. The Company previously determined the common stock subject to possible redemption to be equal to the redemption value of $10.00 per share of common stock, while also taking into consideration a redemption cannot result in net tangible assets being less than $5,000,001.

Subsequently, upon further review by the Company’s management and in consultation with the Company’s external accounting advisor, management determined that the common stock issued during the IPO can be redeemed or become redeemable subject to the occurrence of future events considered outside the Company’s control. Therefore, management concluded that the redemption value should include all shares of common stock subject to possible redemption, resulting in the common stock subject to possible redemption being equal to their redemption value. As a result, management has noted a classification error related to temporary equity and permanent equity in its historical financial statements. This resulted in the need for a restatement of the initial carrying value of the common stock subject to possible redemption with the offset recorded to additional paid-in capital and common stock. In light of this, on November 18, 2021, the Company’s management and the Audit Committee of the Company’s Board of Directors (the “Audit Committee”) concluded that (i) certain items on the Company’s previously issued audited balance sheet dated as of March 5, 2021, which were related to the IPO, (ii) the Company’s financial statements as of and for the period ended March 31, 2021 and (iii) the Company’s financial statements as of and for the period ended June 30, 2021 (the “Relevant Periods”) should no longer be relied upon and that it is appropriate to restate the Company’s financial statements for the Relevant Periods. The Company will restate such financial statements in its Quarterly Report on Form 10-Q for the period ended September 30, 2021 to be filed with the Securities and Exchange Commission as soon as practicable.

In addition, the Company’s management concluded that the Company’s disclosure controls and procedures were not effective, due solely to the material weakness in the Company’s internal control over financial reporting related to the Company’s accounting for complex financial instruments, and specifically as a result of the fact that the Company improperly valued the common stock subject to possible redemption. As a result, the Company performed additional analysis as deemed necessary to ensure that the Company’s financial statements were prepared in accordance with U.S. generally accepted accounting principles.

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.
