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

On April 12, 2021, the Staff of the Securities and Exchange Commission (the “SEC”) released Staff Statement on Accounting and Reporting Considerations for Warrants Issued by Special Purpose Acquisition Companies (“SPACs”) (the “SEC Statement”). The SEC Statement informed market participants that warrants issued by SPACs may require classification as a liability of the entity measured at fair value, with changes in fair value during each period reported in earnings. At issuance on March 8, 2021 in connection with its initial public offering (“IPO”), the outstanding warrants (the “Warrants”) to purchase shares of Class A common stock of Atlantic Coastal Acquisition Corp. (the “Company”) were accounted for as equity within the Company’s balance sheet.

On May 14, 2021, the Audit Committee of the Board of Directors of the Company (the “Audit Committee”) concluded, after discussion and evaluation with the Company’s management, including with Marcum LLP (“Marcum”), the Company’s independent registered public accounting firm, that the Company’s audited balance sheet as of March 8, 2021 filed as Exhibit 99.1 to the Company’s Current Report on Form 8-K filed with the SEC on March 12, 2021 should no longer be relied upon due to changes required to reclassify the Warrants as liabilities to align with the requirements set forth in the SEC Statement. The Company plans to reflect this reclassification of the Warrants for in its upcoming Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2021, to be filed with SEC.

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

In addition, the audit report of Marcum included in the Current Report on Form 8-K filed with the SEC on March 12, 2021 should no longer be relied upon.
