The principal occupations and positions and directorships for at least the past five years of our directors and director nominees, as well as certain information regarding their individual experience, qualifications, attributes and skills that led our Board of Directors to conclude that they should serve on the Board of Directors, are described below.

In identifying and evaluating potential candidates, the nominating and corporate governance committee will consider several factors, including, without limitation, high personal and professional integrity, strong ethics and values, the ability to make mature business judgments, experience in corporate management such as serving as an officer or former officer of a publicly held company, experience as a board member of another publicly held company, professional and academic experience relevant to our business, leadership skills, experience in finance and accounting, or executive compensation practices, whether a candidate has the time required for preparation, participation and attendance at board of directors meetings and committee meetings, if applicable, independence, and the ability to represent the best interests of the Company's stockholders.

***Code of Ethics***

We have adopted a code of ethics that applies to all of our directors, officers and employees in accordance with applicable federal securities laws. A copy of our code of ethics is available on our website at www.abpro.co. We also intend to post on our website all disclosures that are required by law or the listing standards of Nasdaq concerning any amendments to, or waivers from, any provision of the code of ethics rather than by filing a Current Report on Form 8-K.

**EXECUTIVE OFFICERS**

Biographical data for Mr. Miles Suk, our current executive officer is included under the heading, "Board of Directors and Committees of the Board" above.

*Clawback Policy*

The Clawback Policy (the "Clawback Policy") was adopted in October 2023. Under the policy, in the event the Company is required to prepare an accounting restatement due to material noncompliance of the Company with any financial reporting requirement under the U.S. federal securities laws, the Board will take, in its discretion, such action it deems necessary to recover from its executive officers who received incentive-based compensation, based on performance in a year for which the Company is required to prepare restated financial statements, the excess of what would have been paid to the executive officer under the accounting restatement. This applies during a lookback period of three years, and the amounts to be reclaimed are as determined by the Board in its sole discretion. For purposes of the Clawback Policy, an executive officer is any of the Company's officers who are required, or who have been required during the immediately preceding three calendar years, to file reports pursuant to Section 16 of the Exchange Act as well as the Company's Chief Legal Officer, if not included. This policy may, in certain circumstances, be applied to other current or former employees whose actions or omissions contributed to the circumstances requiring the restatement and also involved willful misconduct or a willful violation of any of the Company's rules. Additionally, if the Board determines that detrimental conduct has occurred that results in a material adverse impact, any incentive compensation paid during the prior year may be subject to clawback. Incentive compensation excludes base salary and other compensation but includes equity compensation and bonuses.

In October 2022, the SEC adopted new Rule 10D-1 under the Exchange Act, which requires national securities exchanges, including Nasdaq, to establish listing standards relating to executive officer incentive compensation clawback and disclosure rules. In February 2023, Nasdaq released its final version of the proposed listing standards, which require listed companies to adopt, no later than December 1, 2023, clawback policies providing for the recovery of erroneously awarded incentive-based compensation.

*Compensation Committee Interlocks and Insider Participation*

None of our executive officers currently serves, and in the past year has not served, as a member of the compensation committee of any entity that has one or more executive officers serving on our Board.

*Shareholder and Interested Party Communications*

Stockholders and interested parties may communicate with our Board, any committee chairperson or the non-management directors as a group by writing to the board or committee chairperson in care of Abpro Holdings, Inc., 100 Summit Drive, Burlington, MA 01803. Each communication will be forwarded, depending on the subject matter, to the Board, the appropriate committee chairperson or all non-management directors.

*Limitations of Liability and Indemnification of Directors and Officers*

Our Charter limits a directors' liability to the fullest extent permitted under the DGCL. The DGCL provides that directors of a corporation will not be personally liable for monetary damages for breach of their fiduciary duties as directors, except for liability:

● for any transaction from which the director derives an improper personal benefit;

● for any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;

● for any unlawful payment of dividends or redemption of shares; or

● for any breach of a director's duty of loyalty to the corporation or its stockholders.

If the DGCL is amended to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of the directors will be eliminated or limited to the fullest extent permitted by the DGCL, as so amended.

Delaware law and the Bylaws provide that the Company will, in certain situations, indemnify its directors and officers and may indemnify other employees and other agents, to the fullest extent permitted by law. Any indemnified person is also entitled, subject to certain limitations, to advancement, direct payment, or reimbursement of reasonable expenses (including attorneys' fees and disbursements) in advance of the final disposition of the proceeding.

In addition, the Company will enter into separate indemnification agreements with its directors and officers. These agreements, among other things, require the Company to indemnify its directors and officers for certain expenses, including attorneys' fees, judgments, fines, and settlement amounts incurred by a director or officer in any action or proceeding arising out of their services as one of its directors or officers or any other company or enterprise to which the person provides services at its request.

The Company plans to maintain a directors' and officers' insurance policy pursuant to which its directors and officers are insured against liability for actions taken in their capacities as directors and officers. We believe these provisions in the Charter and the Bylaws and these indemnification agreements are necessary to attract and retain qualified persons as directors and officers.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers, or control persons, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

**Item 11. Executive Compensation.**

We are currently considered an "emerging growth company" within the meaning of the Securities Act for purposes of the SEC's executive compensation disclosure rules. Accordingly, we are required to provide a Summary Compensation Table, as well as limited narrative disclosures regarding executive compensation for our last two completed fiscal years and an Outstanding Equity Awards at Fiscal Year End Table for our last completed fiscal year. These reporting obligations extend only to the following "named executive officers," who are the individuals who served as our principal executive officer and the next two most highly compensated executive officers at the end of the fiscal year 2025.

This section discusses material components of the executive compensation programs for the Company's executive officers who area named in the "Summary Compensation Table" below. In 2025, the Company's "named executive officers" and their positions were as follows:

- Miles Suk, Chief Executive Officer and Chairman of the Board;

- Ian Chan, the former Chief Executive Officer; and

- Robert Markelewicz, the former Chief Medical Officer.

This discussion may contain forward-looking statements that are based on the Company's current plans, considerations, expectations, and determinations regarding future compensation programs.

**SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT**

The following table sets forth information regarding the beneficial ownership of shares of our Common Stock upon the completion by each person known by us to be the beneficial owner of more than 5% of the Company's Common Stock, each director and each of our named executive officers.

Beneficial ownership is determined according to the rules of the SEC, which generally provide that a person has beneficial ownership of a security if he, she or it possesses sole or shared voting or investment power over that security, including options and warrants that are currently exercisable or exercisable within 60 days.

The beneficial ownership of Common Stock in the table below is based on 5,896,048 shares Common Stock issued and outstanding as of April 24, 2026. The issued and outstanding shares of Common Stock does not include 184,141 shares reserved for future issuance pursuant to rollover RSUs and options of Abpro Corporation and 208,025 shares of Common Stock reserved for future issuance under the 2024 Incentive Plan. The below table excludes the Common Stock underlying the Warrants, because these securities are not exercisable until registered, which may or may not occur within sixty (60) days.

Unless otherwise indicated, the Company believes that all persons named in the table have sole voting and investment power with respect to all common shares beneficially owned by them. Unless otherwise noted, the business address of each of the following entities or individuals is 100 Summit Drive, Burlington, MA 01803.

**Item 13. Certain Relationships and Related Transactions, and Director Independence.**

**Policies and Procedures for Related Party Transactions**

Our Code of Business Conduct and Ethics requires us to avoid, wherever possible, all related party transactions that could result in actual or potential conflicts of interests, except under guidelines approved by the Board (or the audit committee). Related-party transactions are defined as transactions in which (1) the aggregate amount involved will or may be expected to exceed $120,000 in any calendar year, (2) we or any of our subsidiaries is a participant, and (3) any (a) executive officer, director or nominee for election as a director, (b) greater than 5% beneficial owner of our shares of common stock, or (c) immediate family member of the persons referred to in clauses (a) and (b), has or will have a direct or indirect material interest (other than solely as a result of being a director or a less than 10% beneficial owner of another entity). A conflict of interest situation can arise when a person takes actions or has interests that may make it difficult to perform his or her work objectively and effectively. Conflicts of interest may also arise if a person, or a member of his or her family, receives improper personal benefits as a result of his or her position.

Our audit committee, pursuant to its written charter, is responsible for reviewing and approving related-party transactions to the extent we enter into such transactions. The audit committee will consider all relevant factors when determining whether to approve a related party transaction, including whether the related party transaction is on terms no less favorable to us than terms generally available from an unaffiliated third-party under the same or similar circumstances and the extent of the related party's interest in the transaction. No director may participate in the approval of any transaction in which he is a related party, but that director is required to provide the audit committee with all material information concerning the transaction. We also require each of our directors and executive officers to complete a directors' and officers' questionnaire that elicits information about related party transactions.

These procedures are intended to determine whether any such related party transaction impairs the independence of a director or presents a conflict of interest on the part of a director, employee or officer.

To further minimize conflicts of interest, we have agreed not to consummate an initial business combination with an entity that is affiliated with any of the Sponsor or our officers or directors including (i) an entity that is either a portfolio company of, or has otherwise received a material financial investment from, any private equity fund or investment company (or an affiliate thereof) that is affiliated with any of the foregoing, (ii) an entity in which any of the foregoing or their affiliates are currently passive investors, (iii) an entity in which any of the foregoing or their affiliates are currently officers or directors, or (iv) an entity in which any of the foregoing or their affiliates are currently invested through an investment vehicle controlled by them, unless we have obtained an opinion from an independent investment banking firm, or another independent entity that commonly renders valuation opinions on the type of target business we are seeking to acquire, and the approval of a majority of our disinterested independent directors that the business combination is fair to our unaffiliated stockholders from a financial point of view. Furthermore, no finder's fees, reimbursements, consulting fee, monies in respect of any payment of a loan or other compensation will be paid by us to the Sponsor, our officers or directors, or any of their respective affiliates, for services rendered to us prior to, or in connection with any services rendered in order to effectuate, the consummation of our initial business combination (regardless of the type of transaction that it is), other than the repayment of any loans from the Sponsor, officers and directors for working capital purposes and reimbursement of any out-of-pocket expenses incurred in connection with activities on our behalf such as identifying potential target businesses and performing due diligence on suitable business combinations.

**Related Party Transactions**

In addition to the compensation arrangements, including employment, termination of employment and change in control arrangements discussed above in the sections titled "Director Compensation" and "Executive Compensation," we describe below transactions and series of similar transactions, since the beginning of our last fiscal year, to which we were a party or will be a party, in which:

● the amounts involved exceeded or will exceed $120,000; and

● any of our directors, nominees for director, executive officers or holders of more than 5% of our outstanding capital stock, or any immediate family member of, or person sharing the household with, any of these individuals or entities, had or will have a direct or indirect material interest.

***Consulting Agreement with CEO***

On July 20, 2025, the Company entered into a consulting agreement with the Company's CEO (the "CEO Consulting Agreement"). In connection with the CEO Consulting Agreement, the Company issued 16,667 RSUs, which vest in three equal installments on March 3, 2026, March 3, 2027, and March 3, 2028, and provides for an annual compensation of $300,000. The term of the CEO Consulting Agreement commenced on March 3, 2025, the date the Company's board of directors appointed the CEO and shall remain in full force and effect until terminated by mutual written agreement between the Company and the CEO, or by sixty days' prior written notice by either party. Under the terms of the CEO Consulting Agreement, the Company is obligated to make the payment equal to three times the fair market value of the CEO's equity interests in the Company, if within 12 months of a change of control event (as defined in the CEO Consulting Agreement), the CEO is involuntarily terminated without cause or resigns for good reason. The Company made total payments of $75,000 under the CEO Consulting Agreement during the year ended December 31, 2025, and the unpaid amounts owed under the CEO Consulting agreement were $175,000 as of December 31, 2025.

***Loan Agreement with CEO***

In January 2026, the Company entered into a loan agreement with its Chief Executive Officer and Chairman for an unsecured loan in the principal amount of $147,000 to fund the premium for the Company's directors' and officers' liability insurance. The loan had a nine-month term from the date of advance and may be prepaid at any time without penalty. No interest accrued during the first three months following funding; thereafter, the outstanding principal bore interest at a variable rate equal to three-month Term SOFR plus 2.0% per annum, with any accrued interest payable at maturity or upon earlier repayment. The loan was not secured by any collateral and is not guaranteed by any third party.

**Other Transactions**

We have granted stock options and RSUs to our named executive officers and our directors. See the sections titled "Director Compensation" and "Executive Compensation," for a description of these stock options and RSUs. In the ordinary course of business, we enter into offer letters and employment agreements with our executive officers. We will also enter into indemnification agreements with our directors and officers. The indemnification agreements and our certificate of incorporation and bylaws require us to indemnify our directors and officers to the fullest extent permitted by Delaware law.

**Director Independence**

Our Board of Directors has determined that Messrs. Karatas and Yoon and Ms. Gunn, representing three of our four directors, are "independent" as that term is defined under the rules of The Nasdaq Stock Market, as further described in the section titled "Corporate Governance—Director Independence" above.

**Item 14. Principal Accounting Fees and Services.**
