Amendment No. 1 to Business Combination Agreement

On September 4, 2024, Atlantic Coastal Acquisition Corp. II (“ACAB”) entered into an amendment to the business combination agreement (as amended, the “Business Combination Agreement”) with Abpro Corporation (“Abpro”) and Abpro Merger Sub Corp., pursuant to which 600,601 shares of Series A common stock of the surviving company will be issued at closing to ACAB’s sponsor, Atlantic Coastal Management II LLC (the “Sponsor”) in lieu of repayment of $2,000,000 of Unpaid SPAC Expenses (as defined in the Business Combination Agreement) owed to the Sponsor as a result of advances made by the Sponsor to ACAB.

The information disclosed under Item 1.01 of this Report is incorporated into this Item 3.02 to the extent required herein. The securities of ACAB that may be issued to the Sponsor under the Business Combination Agreement will not be registered under the Securities Act of 1933, as amended (the “Securities Act”) in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act and/or Regulation D promulgated thereunder.

The information set forth below under this Item 7.01, including the exhibits attached hereto, is intended to be furnished and shall not be deemed “filed” for purposes of Section 18 of the Exchange Act of 1934 (the “Exchange Act”) or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act or the Exchange Act, except as expressly set forth by specific reference in such filing.

Important Information and Where to Find It

In connection with the Business Combination and the transactions contemplated thereby (the “Proposed Transactions”), ACAB has filed a Registration Statement on Form S-4, with the SEC, which includes the Proxy/Information Statement to be distributed to holders of ACAB’s common stock in connection with ACAB’s solicitation of proxies for the vote by ACAB’s stockholders with respect to the Proposed Transactions and other matters as described in the Registration Statement, a prospectus relating to the offer of the securities to be issued to stockholders in connection with the Proposed Transactions, and an information statement to Company’s stockholders regarding the Proposed Transactions. After the Registration Statement has been declared effective, ACAB will mail a definitive proxy statement/prospectus, when available, to its stockholders. Investors and security holders and other interested parties are urged to read the proxy statement/prospectus, any amendments thereto and any other documents filed with the SEC carefully and in their entirety because they contain important information about ACAB, the Company and the Proposed Transactions. When available, investors and security holders may obtain free copies of the Proxy/Information Statement and definitive proxy statement/prospectus and other documents filed with the SEC by ACAB through the website maintained by the SEC at http://www.sec.gov, or by directing a request to: Atlantic Coastal Acquisition Corp. II, 6 St Johns Lane, Floor 5 New York, NY 10013.

Participants in the Solicitation

ACAB and the Company and their respective directors and certain of their respective executive officers and other members of management and employees may be considered participants in the solicitation of proxies with respect to the Proposed Transactions. Information about the directors and executive officers of ACAB is set forth in its Annual Report on Form 10-K for the fiscal year ended December 31, 2023. Additional information regarding the participants in the proxy solicitation and a description of their direct and indirect interests, by security holdings or otherwise, are included in the Registration Statement and other relevant materials filed or to be filed with the SEC regarding the Proposed Transactions. Stockholders, potential investors and other interested persons should read the Registration Statement carefully before making any voting or investment decisions. When available, these documents can be obtained free of charge from the sources indicated above.

No Offer or Solicitation

This Current Report on Form 8-K shall not constitute an offer to sell or the solicitation of an offer to buy any securities, nor shall there be any sale of securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. No offering of securities shall be made except by means of a prospectus meeting the requirements of Section 10 of the Securities Act.

Forward-Looking Statements

This Current Report on Form 8-K includes certain statements that are not historical facts but are forward-looking statements for purposes of the safe harbor provisions under the United States Private Securities Litigation Reform Act of 1995. Forward-looking statements generally are accompanied by words such as “believe”, “project”, “expect”, “anticipate”, “estimate”, “intend”, “strategy”, “future”, “opportunity”, “plan”, “may”, “should”, “will”, “would”, “will be”, “will continue”, “will likely result” or similar expressions. that predict or indicate future events or trends or that are not statements of historical matters. These forward-looking statements include, but are not limited to, statements regarding estimates and forecasts of revenue and other financial and performance metrics and projections of market opportunity and expectations, ACAB’s ability to enter into definitive agreements or consummate a transaction with the Company; ACAB’s ability to obtain the financing necessary consummate the Proposed Transactions; and the expected timing of completion of the Proposed Transactions. These statements are based on various assumptions and on the current expectations of ACAB’s and the Company’s management and are not predictions of actual performance. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on by any investor as, a guarantee, an assurance, a prediction or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and will differ from assumptions. Many actual events and circumstances are beyond the control of ACAB and the Company. These forward looking statements are subject to a number of risks and uncertainties, including general economic, financial, legal, political and business conditions and changes in domestic and foreign markets; the outcome of judicial proceedings to which the Company is, or may become a party; the inability of the parties to enter into definitive agreements or successfully or timely consummate the Proposed Transactions or to satisfy the other conditions to the closing of the Proposed Transactions, including the risk that any required regulatory approvals are not obtained, are delayed or are subject to unanticipated conditions that could adversely affect the combined company; the risk that the approval of the stockholders of ACAB for the Proposed Transactions is not obtained; failure to realize the anticipated benefits of the Proposed Transactions, including as a result of a delay in consummating the Proposed Transaction or difficulty in, or costs associated with, integrating the businesses of ACAB and the Company; the amount of redemption requests made by ACAB’s stockholders; the occurrence of events that may give rise to a right of one or both of ACAB and the Company to terminate the Business Combination Agreement; risks related to the rollout of the Company’s business and the timing of expected business milestones; the effects of competition on the Company’s future business; and those factors discussed in ACAB’s Registration Statement on Form S-1 filed with the SEC on January 18, 2022, the Registration Statement on Form S-4 filed with the SEC on April 2, 2024, the Annual Report on Form 10-K for the fiscal year ended December 31, 2023 and the Quarterly Reports on Form 10-Q for the fiscal quarters ended March 31, 2024 and June 30, 2024 under the heading “Risk Factors,” and other documents of ACAB filed, or to be filed, with the SEC. If the risks materialize or assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. There may be additional risks that neither ACAB nor the Company presently know or that ACAB and the Company currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect ACAB’s and the Company’s expectations, plans or forecasts of future events and views as of the date of this Current Report on Form 8-K. ACAB and the Company anticipate that subsequent events and developments will cause their assessments to change. However, while ACAB and the Company may elect to update these forward-looking statements at some point in the future, ACAB and the Company specifically disclaim any obligation to do so. These forward-looking statements should not be relied upon as representing ACAB’s or the Company’s assessments as of any date subsequent to the date of this Current Report on Form 8-K. Accordingly, undue reliance should not be placed upon the forward-looking statements. Neither ACAB nor the Company gives any assurance that either ACAB or the Company, or the combined company, will achieve its objectives.
