FORM OF AUDIT COMMITTEE CHARTER

(As adopted by the Board of Directors effective as of [●], 2021)

Purpose

The purpose of the Audit Committee, and its subcommittees, as applicable (the “Committee”), of the Board of Directors (the “Board”) of Atlantic Coastal Acquisition Corp. (the “Company”) is to:

(1) assist the Board in its oversight of:

(a) the integrity of the Company’s financial statements;

(b) the Company’s compliance with legal and regulatory requirements;

(c) the qualification, independence, and performance of the Company’s independent auditors; and

(d) the performance of the Company’s internal audit function; and

(2) oversee the Company’s accounting and financial reporting processes and the audit of the Company’s Financial statements.

Membership

The Committee shall consist of at least three members of the Board, with the exact number to be determined by the Board. Committee members shall be appointed from time to time by the Board, having given consideration to the recommendations, if any, from the Nominating and Corporate Governance Committee, but not less than annually at its first meeting following the Annual Meeting of Stockholders. Also having given consideration to the recommendation of the Nominating and Corporate Governance Committee, if any, the Board shall designate a Chair of the Committee, provided that if the Board does not so designate a Chair the members of the Committee, by a majority vote, may designate a Chair. The Chair (or in his or her absence a member designated by the Chair) shall preside at all meetings of the Committee.

Committee members may be removed, without cause, by the affirmative vote of the majority of the Board at any time. Any Committee member may resign effective upon giving oral or written notice to the Chairman of the Board, the Corporate Secretary, or the Board (unless the notice specifies a later time for the effectiveness of such resignation).

Each member of the Committee shall meet the independence standards and experience requirements that may be established from time to time by the Nasdaq Stock Market (“Nasdaq”) and the SEC and are applicable to the Committee, provided that the exemptions from the independence requirements set forth in such rules and regulations shall also be applicable to members of the Committee. Each member of the Committee shall also meet any additional independence standards that may be established from time to time by the Board or the Nominating and Corporate Governance Committee. Each member of the Committee must be financially literate, as determined by the Board (e.g., able to read and understand fundamental financial statements, including the Company’s balance sheet, income statement, and cash flow statement), and must have past employment experience in finance or accounting, requisite professional certification in accounting or other comparable experience or background, as determined by the Board, that leads to financial sophistication. The Board may presume that a member who qualifies as an “audit committee financial expert” as defined in item 407(d)(5)(ii) of Regulation S-K has the requisite financial sophistication. No member of the Committee may have participated in preparing the Company’s financial statements at any time in the past three years.

Resources and Authority

The Committee shall have the resources and appropriate authority, without seeking the approval of the Board, to discharge its responsibilities, including the authority to retain, at the Company’s expense, outside legal, accounting, or other consultants to advise the Committee and to authorize or conduct investigations into any matters within the scope of its responsibilities and to approve related fees and retention terms. The Committee may request any director, officer, or employee of the Company, the Company’s outside counsel, independent auditors, or such other persons as it deems appropriate to attend a meeting of the Committee or to meet with any members of, or consultants to, the Committee. The Committee may also exclude from its meetings any persons it deems appropriate in order to carry out its responsibilities. The Committee shall have full access to all books, records, facilities, and personnel of the Company in connection with the discharge of its responsibilities.

Delegation to Subcommittee

The Committee may form and delegate authority to subcommittees consisting of one or more members of the Committee when appropriate, including the authority to grant pre-approvals of audit and permitted non-audit services, as are provided in the resolutions of the Committee, except to the extent such delegation is limited by applicable law or listing standard. The actions of any such subcommittee shall be presented to the full Committee at the next scheduled Committee meeting.

Clarification of Audit Committee’s Role

· While the Committee has the responsibilities and powers set forth in this Charter, the Committee’s role is one of oversight. It is not the duty of the Committee to plan or conduct audits or to determine that the Company’s financial statements and disclosures are complete and accurate and are in accordance with generally accepted accounting principles, applicable rules, and regulations. These are the responsibilities of management and the independent auditors. In adopting this Charter, the Board acknowledges that the Committee members are not providing any expert or special assurance as to the Company’s financial statements or any professional certification as to the independent auditors’ work or auditing standards. Each member of the Committee is entitled to rely on the integrity of those persons and organizations within and outside the Company that provide information to the Committee and the accuracy and completeness of the financial and other information provided to the Committee by such persons and organizations absent actual knowledge to the contrary.
