This Amendment supplements and amends the Proxy Statement for the Annual Meeting to amend Proposal No. 3 as described more fully herein. This Amendment is being made available to shareholders beginning on or about October 6, 2025. Except as amended or superseded, all information set forth in the Proxy Statement remains unchanged and is important for you to review and consider before voting. In order to comply with Nasdaq listing requirements and avoid delisting, Proposal 3 is being amended to authorize our management to effect a reverse stock split of our issued and outstanding shares of common stock at a specific ratio of one-for-thirty (the “Reverse Stock Split”). This Reverse Stock Split, if effected, will be authorized by an amendment to our Certificate of Incorporation. The revised stockholder resolution for Amended Proposal 3 is set forth under the heading “Amended Proposal 3: Approval of Reverse Stock Split” on page 2 of this Amendment. This Amendment, our Proxy 2024 (including the Annual Report on Form 10-K for the fiscal year ended December 31, 2024), and related information prepared in connection with the Annual Meeting are available at https://www.cstproxy.com/abpro/am2025.

From and after the date of this Amendment, all references to the “Proxy Statement” are to the Proxy Statement as amended hereby. The Proxy If you have already returned your proxy card or voting instruction form, your votes on Proposal 1 and Proposal 2 remain valid and will be voted at the Annual Meeting. However, because the terms of Proposal 3 have been materially changed from a 1-for-10 ratio to a 1-for-30 ratio, any prior vote you submitted on Proposal 3 is no longer valid. To vote on the revised Proposal 3, or if you wish to change or revoke your vote on any proposal, you must submit a new proxy card or voting instruction form. Please refer to the disclosure in the Proxy Statement under “Questions and Answers About the Annual Meeting - Can I change my vote after submitting my proxy?,” on page 40 of the Proxy Statement for instructions on how to do so. AMENDED PROPOSAL 3 APPROVAL OF REVERSE STOCK SPLIT Overview Our Board has determined that it is advisable and in the best interests of the Company and its stockholders, for us to amend our Certificate of Incorporation to authorize our management to effect a reverse stock split (the “Reverse Stock Split Charter Amendment”) of our issued and outstanding shares of our common stock at a specific ratio of one-for-thirty (the “Split Ratio” and such reverse stock split at the Split Ratio, the “Reverse Stock Split”). A vote for this Amended Proposal 3 will constitute approval of the Reverse Stock Split that, once authorized by management and effected by filing the Reverse Stock Split Charter Amendment with the Secretary of State of the State of Delaware, will combine 30 shares of our common stock into one share of our common stock. If implemented, the Reverse Stock Split will have the effect of decreasing the number of shares of our common stock issued and outstanding. As used herein, “management” means the Company’s Chief Executive Officer. Accordingly, stockholders are asked to adopt and approve the Reverse Stock Split Cha
