On April 5, 2022, Ronald C. Warrington tendered his resignation as the Chief Financial Officer of Atlantic Coastal Acquisition Corp. (the “Company”). Effective as of that date, Mr. Warrington ceased to serve as the Chief Financial Officer of the Company.

On April 11, 2022, the Board of Directors of the Company appointed Jason Chryssicas to serve as the Company’s Chief Financial Officer effective that same day. Mr. Chryssicas, age 37, has served as an advisor to the Company since May 2021. Mr. Chryssicas also serves as the Chief Financial Officer and a director of Atlantic Coastal Acquisition Corp. II, a separate blank check company formed for the purpose of effecting a merger, share exchange, asset acquisition, stock purchase, recapitalization, reorganization or similar business combination with one or more businesses, since October 2021. Prior to that, Mr. Chryssicas served in a variety of leadership positions within financial services and capital markets, including Investor Relations, Investment Banking, Corporate Development and Strategy. Since 2013, Mr. Chryssicas has served in various roles at the financial services companies Cantor Fitzgerald, L.P. and BGC Partners Inc., including his current role as Head of Investor Relations at both firms. As previously disclosed, on February 9, 2022, the Company terminated its proposed business combination with Essentium, Inc., a Delaware corporation (the “Terminated Transaction”). In connection with the Terminated Transaction, Cantor Fitzgerald & Co., an affiliate of Cantor Fitzgerald, L.P., was engaged by the Company as advisor and placement agent. Cantor Fitzgerald Securities, an affiliate of Cantor Fitzgerald, L.P., was engaged by Atlantic Coastal Finance Company LLC (a wholly-owned subsidiary of the Company’s sponsor, Atlantic Coastal Acquisition Management LLC) as lender.

The selection of Mr. Chryssicas as Chief Financial Officer was not pursuant to any arrangement or understanding with respect to any other person. There are no family relationships between Mr. Chryssicas and any director or executive officer of the Company, and there are no transactions between Mr. Chryssicas and the Company that would be required to be reported under Item 404(a) of Regulation S-K.

On April 11, 2022, the Company entered into an indemnity agreement (the “Indemnity Agreement”) with Mr. Chryssicas, pursuant to which the Company has agreed to provide contractual indemnification against liabilities that may arise by reason of his respective service to the Company, in the form previously filed as Exhibit 10.6 to the Company’s Registration Statement on Form S-1 (File No. 333-253003) for its initial public offering, initially filed with the U.S. Securities and Exchange Commission on February 11, 2021 (as amended, the “Registration Statement”). The foregoing description of the Indemnity Agreement does not purport to be complete and is qualified in its entirety by reference to the form of Indemnity Agreement, a copy of which is attached as Exhibit 10.6 to the Registration Statement and is incorporated herein by reference.
