This Current Report on Form 8-K is filed by Plum Acquisition Corp. I, a Cayman Islands exempted company (the “Company”), in connection with the matters described herein.

Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On May 28, 2021, the Company received a deficiency letter from the Nasdaq Capital Market (“NASDAQ”) indicating that it is not in compliance with Section 5250(c) of the NASDAQ Rules and Regulations as a result of its failure to timely file the Form 10-Q for the fiscal quarter ended March 31, 2021 (the “Form 10-Q”).

On April 12, 2021, the staff of the Securities and Exchange Commission (“SEC”) issued a public statement entitled “Staff Statement on Accounting and Reporting Considerations for Warrants Issued by Special Purpose Acquisition Companies (“SPACs”)” (the “Statement’), which clarified guidance for all SPAC-related companies regarding the accounting and reporting for their warrants. The immediacy of the effective date of the new guidance set forth in the Statement has resulted in a significant number of SPACs re-evaluating the accounting treatment for their warrants with their professional advisors, including auditors and other advisors responsible for assisting SPACs in the preparation of financial statements. This, in turn, has resulted in the Company’s delay in preparing and finalizing its financial statements as of and for the quarter ended March 31, 2021 and filing its Form 10-Q with the SEC by the prescribed deadline.

Under the NASDAQ’s rules, the Company has 60 calendar days from the date of the deficiency letter to submit to NASDAQ a plan to regain compliance with the NASDAQ Listing Rules. Concurrently with the filing of this Current Report on Form 8-K, the Company is filing the Form 10-Q.

Item 4.02 Non-Reliance on Previously Issued Financial Statement and Related Audit Report.

On April 12, 2021, the staff of the SEC issued the Statement. In the Statement, the SEC staff expressed its view that certain terms and conditions common to SPAC warrants may require the warrants to be classified as liabilities on SPACs’ balance sheets as opposed to equity. At issuance on March 18, 2021, the outstanding Warrants of the Company to purchase its Class A ordinary shares were accounted for as equity within its balance sheet, and after discussion and evaluation, the Company has concluded that its Warrants should be presented as liabilities as of the IPO date, reported at fair value with subsequent fair value changes to be recorded in its financial statements at each reporting period. Management discussed this evaluation and conclusion with its independent registered public accounting firm, Marcum LLP, (“Marcum”).

On June 1, 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 18, 2021 filed as Exhibit 99.1 to the Company’s Current Report on Form 8-K filed with the SEC on March 18, 2021 (the “Form 8-K”) should no longer be relied upon due to changes required to reclassify the Warrants as liabilities to align with the guidance set forth in the Statement. The Company has reflected this reclassification of the Warrants in its Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2021, filed with the SEC on June 4, 2021.

The Company does not expect any of the above changes will have any impact on its cash position or cash held in its trust account.

In addition, the audit report of Marcum included in the Company’s Form 8-K filed on March 18, 2021 should no longer be relied upon.
