| Amendment Description | Anzu Special Acquisition Corp I (the “Company”) is filing this Amendment No. 1 on Form 8-K/A (the “Amendment”) to amend and restate the Company’s audited balance sheet as of March 4, 2021 that had been filed with the Company’s Current Report on Form 8-K originally filed with the U.S. Securities and Exchange Commission (the “SEC”) on March 10, 2021 (the “Original 8-K”). The audited balance sheet is being restated to reflect the classification of all of the shares of the Company’s Class A common stock as temporary equity in accordance with Accounting Standards Codification (“ASC”) 480-10-S99. The Company had previously classified a portion of its shares of Class A common stock as permanent equity. On December 2, 2021, the Audit Committee of the Board of Directors of the Company concluded, after discussion with the Company’s management, that the Company’s audited balance sheet as of March 4, 2021 filed as Exhibit 99.1 to the Original 8-K should no longer be relied upon due to the aforementioned changes required to reclassify the shares of Class A common stock as temporary equity to align with ASC 480-10-S99. The Audit Committee of Board of Directors of the Company discussed with the Company’s independent accountants and are in agreement with the matters as disclosed in this Amendment. The correction of the aforementioned classification of the shares of Class A common stock as temporary equity is reflected in Exhibit 99.1 included with this Amendment. 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. The Company’s controls over financial reporting did not provide for the proper classification of the shares of Class A common stock within the Company’s financial statements. As such, this represented a material weakness in the Company’s internal controls. |
