NOTE 1 - ORGANIZATION AND PLAN OF BUSINESS OPERATIONS

Atlantic Coastal Acquisition Corp. II ("ACAB", now known as Abpro Holdings, Inc., "Abpro") (the "Company") is a blank check company incorporated in Delaware on May 20, 2021. The Company was formed for the purpose of effectuating a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or other similar business combination with one or more businesses (a "Business Combination"). The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies.

Business Combination

On November 12, 2024, ACAB and Abpro completed a series of transactions that resulted in the combination (the "Closing" of the "Business Combination") of ACAB with Abpro Corporation, a Delaware corporation ("Abpro Corporation"), pursuant to the previously announced Business Combination Agreement, dated December 11, 2023, amended by an amendment dated September 4, 2024 (the "BCA"), by and among ACAB, Abpro Merger Sub Corp., a Delaware corporation and a wholly owned subsidiary of ACAB ("Merger Sub"), and Abpro Corporation, following the approval at the special meeting of the shareholders of ACAB held on November 7, 2024 (the "Special Meeting"). On November 12, 2024, pursuant to the BCA, and as described in greater detail in the Company's final prospectus and definitive proxy statement, which was filed with the U.S. Securities and Exchange Commission (the "SEC") on October 18, 2024 (the "Proxy Statement/Prospectus"), Merger Sub merged with and into Abpro Corporation, with Abpro Corporation surviving the merger as a wholly owned subsidiary of ACAB, and ACAB changed its name to Abpro Holdings, Inc. ("New Abpro"). As consideration for the Business Combination, New Abpro issued to or reserved for Abpro Corporation shareholders an aggregate of approximately 50,000,000 shares of New Abpro common stock, par value $0.0001 per share (the "Common Stock"), consisting of 39,413,500 shares of Common Stock issued to Abpro Corporation shareholders, and 10,586,500 shares of Common Stock reserved for issuance in connection with certain Abpro Corporation rollover RSUs and stock options (collectively, the "Merger Consideration"). In addition, New Abpro issued an aggregate of 3,367,401 shares of Common Stock to the PIPE investors (as described below), an aggregate of 1,250,000 shares of Common Stock to vendors in connection with the Closing, and Atlantic Coastal Acquisition Management II LLC (the "Sponsor") forfeited and New Abpro cancelled 966,442 shares of Common Stock (further described below).

Under the Second Amended Articles of Incorporation of ACAB dated November 12, 2024, each of the outstanding shares of ACAB Series A Common Stock and the outstanding share of ACAB Class B Common Stock was exchanged into one share of Common Stock.

Unless otherwise defined herein, capitalized terms used in this Quarterly Report on Form 10-Q have the same meaning as set forth in the Proxy Statement/Prospectus.

In connection with the Special Meeting, ACAB shareholders holding 330,276 shares of ACAB's Series A common stock (the "Public Shares") (after giving effect to the share repurchases by Yorkville as described below) exercised their right to redeem their shares for a pro rata portion of the funds in ACAB's trust account (the "Trust Account"). Prior to the Closing approximately $3,752,627 (approximately $11.36 per Public Share) was removed from the Trust Account to pay such holders.

Following the Closing, Abpro's stockholders shall be issued up to 14,500,000 additional shares of the Post-Combination Company common stock ("Earnout Shares") if, within five calendar years after the closing of the Business Combination, the volume weighted average price of shares of Series A Common Stock on Nasdaq, or any other national securities exchange on which the shares of Series A Common Stock are then traded ("VWAP") meets or exceeds three-tier target prices defined in the agreement, as follows:

a)	one-third of the total Earnout Shares, if, the VWAP is greater than or equal to $13.00 over any 20 trading days within any consecutive 30 trading day period (the "First Share Target")

b)	one-third of the total Earnout Shares, if, the VWAP is greater than or equal to $15.00 over any 20 trading days within any consecutive 30 trading day period (the "Second Share Target")

c)	one-third of the total Earnout Shares, if, the VWAP is greater than or equal to $18.00 over any 20 trading days within any consecutive 30 trading day period (the "Third Share Target").

These shares are contingently issuable upon the achievement of the set market performance targets. Considering the underlying contingent consideration to be transferred are common stocks, and as such is indexed to the Post-Combination Company's own stock and classified in stockholders' equity in the statement of financial position, we deemed the contingent payments under the earnout provisions to qualify for the scope exception in Accounting Standards Codification ("ASC") 815-10-15-74(a). As a result, the contingent consideration obligation will be recognized when the contingency is resolved, and the consideration is paid or becomes payable and has no impact on the pro forma condensed financial statements.

Abpro's 61,009 outstanding common stock warrants expired upon the consummation of the Business Combination.

Concurrently with the execution of the BCA, Abpro and Abpro Bio International, Inc. ("Abpro Bio"), an Abpro stockholder, entered into an agreement (the "Sponsor Share Letter"), pursuant to which Sponsor agreed to, at the Closing Date, (i) retain 2,950,000 shares of Series A Common Stock of ACAB, (ii) retain 291,667 shares, and transfer 983,333 shares to Abpro and 983,333 of the shares Abpro Bio ("Promote Shares"), for such parties to use to obtain non-redemption commitments from SPAC stockholders or other capital for SPAC or the Surviving Corporation (with any shares unused for such purpose to be retained by such party), and (iii) forfeit the remainder of any Series A Common Stock and Series B Common Stock held by Sponsor (or 966,441 Series A shares and 1 Series B shares). It was also agreed in the Sponsor Share Letter that the Sponsor will transfer 200,000 shares to one of ACAB's financial advisors for the services provided prior to the merger date. The transfer of 983,333 shares of ACAB Series A Common Stock to Abpro Bio was reflected in the pro forma condensed financial statements as a part of the recapitalization in conjunction with the Business Combination and this transfer has no financial impact. As it relates to 983,333 shares transferred to Abpro, the corresponding issuance costs will be recorded at the date these shares are transferred to third-party investors against non-redemption or capital commitments. If the 983,333 shares of Series A common stock held by Abpro and 291,667 shares held by the Sponsor are transferred to third-party investors in conjunction with their capital commitments, the maximum related costs to be recorded to additional paid-in capital will be in the amount of approximately $14.3 million (based on the fair value of ACAB's common stock shares of $11.20 per share at September 30, 2024) with the corresponding decrease in the paid-in-capital.

Under the terms of the BCA, at the Closing of the Business Combination, the Sponsor received 600,601 shares of common stock of New Abpro in exchange for the extinguishment of $2,000,000 advances to ACAB by the Sponsor.

On November 14, 2024, pursuant to the previously disclosed Standby Equity Purchase Agreement ("SEPA") dated October 30, 2024 with YA II PN, LTD., New Abpro entered into a Convertible Promissory Note ("Yorkville Note") for $3,000,000, and received net proceeds of $2,755,000. The Yorkville Note has a maturity of November 13, 2025, incurs interest at a rate of 0% (or 18% upon the occurrence of an uncured Event of Default), and is redeemable at the option of New Abpro if the VWAP of New Abpro's Common Stock is less than $11.50. Holder has a right to convert any portion of the Yorkville Note at any time at a conversion price equal to the lower of $11.50, 94% of the daily VWAP during the previous 5 consecutive trading days, which may be adjusted downward upon payment of stock dividend, stock split or reclassification, or if New Abpro issues Common Stock for no consideration or at a price lower than the then-effective Fixed Price (as defined in the Yorkville Note).

Business Prior to the Business Combination

As of September 30, 2024, the Company had not yet commenced any operations. All activity for the period May 20, 2021 (inception) through September 30, 2024 relates to the Company's formation, the initial public offering (the "Initial Public Offering"), which is described below, and subsequent to the Initial Public Offering, identifying a target company for a Business Combination. The Company will not generate any operating revenues until after the completion of a Business Combination, at the earliest. The Company will generate non-operating income in the form of interest income from the proceeds derived from the Initial Public Offering.

The registration statement for the Company's Initial Public Offering was declared effective on January 13, 2022. On January 19, 2022, the Company consummated the Initial Public Offering of 30,000,000 units (the "Units" and, with respect to the shares of Series A common stock included in the Units being offered, the "Public Shares"), which includes the partial exercise by the underwriters of its over-allotment option in the amount of 3,900,000 Units at $10.00 per Unit, generating gross proceeds of $300,000,000, which is described in Note 3.

Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 13,850,000 warrants (each, a "Private Placement Warrant" and, collectively, the "Private Placement Warrants") at a price of $1.00 per Private Placement Warrant in a private placement to Atlantic Coastal Acquisition Management II LLC (the "Sponsor"), generating gross proceeds of $13,850,000, which is described in Note 4.

Upon the closing of a Business Combination by the Company, the Sponsor may elect to either receive repayment under the Notes or to convert all or a portion of the amount loaned under the Notes into Series A common stock of the Company at a price equal to $10.20 per share. In the event that the Company does not complete a Business Combination, the amounts loaned under the Notes will be repaid to the Sponsor only from funds held outside the Trust Account or will be forfeited, eliminated, or otherwise forgiven.

On October 14, 2023, by resolution of the board of directors of the Company, the Company extended the expiration date of the Combination Period from October 19, 2023 to November 19, 2023.

Going Concern and Liquidity

At September 30, 2024, the Company had $13,597 in its operating bank accounts and a working capital deficit of $7,480,594.

In connection with the Company's assessment of going concern considerations in accordance with the Financial Accounting Standards Board's ("FASB") Accounting Standards Codification ("ASC") Topic 205-40 "Presentation of Financial Statements-Going Concern," management has determined the future viability of the Company is largely dependent on its ability to raise additional capital to finance its operations. The Company expects to seek additional funding through equity and debt financings, collaboration agreements and research grants. Although the Company has been successful in raising capital in the past, there is no assurance that it will be successful in obtaining such additional financing on terms acceptable to the Company, if at all. If the Company is unable to obtain funding, the Company could be forced to delay, reduce or eliminate its research and development programs, product portfolio expansion or commercialization efforts, which could adversely affect its business prospects.

Accordingly, based on the considerations discussed above, management has concluded there is substantial doubt as to the Company's ability to continue as a going concern within one year after the date the condensed consolidated financial statements are issued. If adequate funds are not available, the Company may require initiating steps to slow cash burn, extending the cash runway until financing can be secured. The unaudited condensed consolidated financial statements do not include any adjustments with respect to the carrying amounts of assets and liabilities and their classification that might result from the outcome of this uncertainty.

Risks and Uncertainties

The impact of current conflicts around the globe, including Russia's invasion of Ukraine and the Israel-Hamas war, and related sanctions, on the world economy is not determinable as of the date of these financial statements, and the specific impact on the Company's financial condition, results of operations, and cash flows is also not determinable as of the date of these financial statements.

Inflation Reduction Act of 2022

On August 16, 2022, the Inflation Reduction Act of 2022 (the "IR Act") was signed into federal law. The IR Act provides for, among other things, a new U.S. federal 1% excise tax on certain repurchases of stock by publicly traded U.S. domestic corporations and certain U.S. domestic subsidiaries of publicly traded foreign corporations occurring on or after January 1, 2023. The excise tax is imposed on the repurchasing corporation itself, not its shareholders from which shares are repurchased. The amount of the excise tax is generally 1% of the fair market value of the shares repurchased at the time of the repurchase. However, for purposes of calculating the excise tax, repurchasing corporations are permitted to net the fair market value of certain new stock issuances against the fair market value of stock repurchases during the same taxable year. In addition, certain exceptions apply to the excise tax. The U.S. Department of the Treasury (the "Treasury") has been given authority to provide regulations and other guidance to carry out and prevent the abuse or avoidance of the excise tax.

Any redemption or other repurchase that occurs after December 31, 2022, in connection with a Business Combination, extension vote or otherwise, may be subject to the excise tax. Whether and to what extent the Company would be subject to the excise tax in connection with a Business Combination, extension vote or otherwise would depend on a number of factors, including (i) the fair market value of the redemptions and repurchases in connection with a Business Combination, extension or otherwise, (ii) the structure of a Business Combination, (iii) the nature and amount of any "PIPE" or other equity issuances in connection with a Business Combination (or otherwise issued not in connection with a Business Combination but issued within the same taxable year of a Business Combination) and (iv) the content of regulations and other guidance from the Treasury. In addition, because the excise tax would be payable by the Company and not by the redeeming holder, the mechanics of any required payment of the excise tax have not been determined. The foregoing could cause a reduction in the cash available on hand to complete a Business Combination and impact the Company's ability to complete a Business Combination.

During the second quarter, the IRS issued final regulations with respect to the timing and payment of the excise tax. Pursuant to those regulations, the Company would need to file a return and remit payment for any liability incurred during the period from January 1, 2023 to December 31, 2023 on or before October 31, 2024. The Company has filed the excise tax return and has engaged the IRS in determining a payment plan for the balance.

The Company is unable to pay its obligation in full, as such it will be subject to additional interest and penalties which are currently estimated at 10% interest per annum and a 5% underpayment penalty per month or portion of a month up to 25% of the total liability for any amount that is unpaid from November 1, 2024 until paid in full.

On April 18, 2023, December 13, 2023, and September 27, 2024 the Company's stockholders redeemed 26,564,308 shares of Series A common stock for a total of $276,471,460, redeemed 2,768,301 shares of Series A common stock for a total of $29,728,990, and redeemed 126,122 shares of Series A common stock for a total of $1,423,594. respectively. The Company evaluated the classification and accounting of the stock redemption under ASC 450, "Contingencies". ASC 450 states that when a loss contingency exists the likelihood that the future events will confirm the loss or impairment of an asset or the incurrence of a liability can range from probable to remote. A contingent liability must be reviewed at each reporting period to determine appropriate treatment. The Company evaluated the current status and probability of completing a Business Combination as of December 31, 2023 and determined that a contingent liability should be calculated and recorded. As of September 30, 2024 and December 31, 2023, the Company recorded $3,076,240 and $3,062,004 of excise tax liability calculated as 1% of shares redeemed, respectively.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") for interim financial information and in accordance with the instructions to Form 10-Q and Article 8 of Regulation S-X of the SEC. Certain information or footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted, pursuant to the rules and regulations of the SEC for interim financial reporting. Accordingly, they do not include all the information and footnotes necessary for a complete presentation of financial position, results of operations, or cash flows. In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all adjustments, consisting of a normal recurring nature, which are necessary for a fair presentation of the financial position, operating results and cash flows for the periods presented.

The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the Company's Annual Report on Form 10-K as filed with the SEC on March 29, 2024. The interim results for the three and nine months ended September 30, 2024 are not necessarily indicative of the results to be expected for the year ending December 31, 2024 or for any future periods.

Emerging Growth Company

The Company is an "emerging growth company," as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the "JOBS Act"), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company's financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

Use of Estimates

The preparation of the unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires the Company's management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period.

Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the unaudited condensed consolidated financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates.

Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiary. All significant intercompany balances and transactions have been eliminated in consolidation.

The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company did nothave any cash equivalents as of September 30, 2024 and December 31, 2023. The Company had $13,597 and $264,538 in cash at September 30, 2024 and December 31, 2023, respectively.

Cash and Marketable Securities Held in Trust Account

At September 30, 2024 and December 31, 2023, all of the Company's investments held in the Trust Account are invested in cash.

As of March 31, 2024, the Company had spent approximately $260,000 of cash for operating expenses with funds related to amounts previously withdrawn from the trust account to pay tax obligations. On May 31, 2024 and June 1, 2024, the Sponsor advanced the Company $245,000 and $25,000, respectively, to fund the account for the funds used in operations.

As of September 30, 2024, the Company had spent approximately $260,000 of cash for operating expenses with funds related to amounts previously withdrawn from the trust account to pay tax obligations.

To mitigate the risk of us being deemed to have been operating as an unregistered investment company (including under the subjective test of Section 3(a)(1)(A) of the Investment Company Act), the Company instructed the Trustee in December 29, 2023 to liquidate the U.S. government securities or money market funds held in the Trust Account and thereafter to hold all funds in the Trust Account in cash (which may include demand deposit accounts) until the earlier of consummation of our Business Combination or liquidation.

Series A Common Stock Subject to Possible Redemption

The Company accounts for its Series A common stock subject to possible redemption in accordance with the guidance in ASC Topic 480, "Distinguishing Liabilities from Equity." Series A Common stock subject to mandatory redemption is classified as a liability instrument and is measured at fair value. Conditionally redeemable common stock (including common stock that features redemption rights that is either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company's control) is classified as temporary equity. At all other times, common stock is classified as a component of stockholders' equity. The Company's Series A common stock feature certain redemption rights that are considered to be outside of the Company's control and subject to occurrence of uncertain future events. Accordingly, at September 30, 2024 and December 31, 2023, Series A common stock subject to possible redemption is presented at redemption value as temporary equity, outside of the stockholders' deficit section of the Company's unaudited condensed consolidated balance sheet.

The Company recognizes changes in redemption value immediately as they occur and adjusts the carrying value of redeemable Series A common stock to equal the redemption value at the end of each reporting period. Increases or decreases in the carrying amount of redeemable Series A common Stock are affected by charges against additional paid-in capital and accumulated deficit.

As of September 30, 2024 and December 31, 2023, the Series A common stock reflected in the unaudited condensed consolidated balance sheet are reconciled in the following table:

Deferred Offering Costs

The Company complies with the requirements of the ASC 340-10-S99-1 and SEC Staff Accounting Bulletin ("SAB") Topic 5A- "Expenses of Offering". Offering costs consist principally of professional and registration fees incurred through the balance sheet date that are related to the Initial Public Offering. Offering costs are allocated based on the relative value of the Public and Private Warrants to the proceeds received from the Public Shares sold in the Initial Public Offering. Offering costs allocated to the Public Shares are charged to temporary equity and offering costs allocated to the Public and Private Warrants are charged to stockholder's equity. As of January 19, 2022, offering costs in the aggregate of $17,204,107, of which an aggregate of $16,699,058 have been charged to temporary equity and an aggregate of $505,049 have been charged to stockholders' equity.

As of September 30, 2024 and December 31, 2023, there were nodeferred offering costs recorded in the accompanying condensed consolidated balance sheets respectively.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist of a cash account in a financial institution, which, at times, may exceed the Federal Deposit Insurance Corporation coverage of $250,000. The Company has not experienced losses on this account and management believes the Company is not exposed to significant risks on such account.

Income Taxes

The Company accounts for income taxes under ASC 740, "Income Taxes." ASC 740 requires the recognition of deferred tax assets and liabilities for both the expected impact of differences between the unaudited condensed financial statements and tax basis of assets and liabilities and for the expected future tax benefit to be derived from tax loss and tax credit carryforwards. ASC 740 additionally requires a valuation allowance to be established when it is more likely than not that all or a portion of deferred tax assets will not be realized. As of September 30, 2024 and December 31, 2023, the Company's deferred tax asset had a full valuation allowance recorded against it. Our effective tax rate was 8.99% and 186.87% for the three months ended September 30, 2024 and 2023, respectively, and 3.48% and 27.88% for the nine months ended September 30, 2024 and 2023, respectively. The effective tax rate differs from the statutory tax rate of 21% for the three and nine months ended September 30, 2024 and 2023, due to changes in the valuation allowance on the deferred tax assets, a prior year true up and non-deductible M&A costs.

While ASC 740 identifies usage of an effective annual tax rate for purposes of an interim provision, it does allow for estimating individual elements in the current period if they are significant, unusual or infrequent. Computing the effective tax rate for the Company is complicated due to the potential impact of the timing of any Business Combination expenses and the actual interest income that will be recognized during the year. The Company has taken a position as to the calculation of income tax expense in a current period based on ASC 740-270-25-3 which states, "If an entity is unable to estimate a part of its ordinary income (or loss) or the related tax (benefit) but is otherwise able to make a reasonable estimate, the tax (or benefit) applicable to the item that cannot be estimated shall be reported in the interim period in which the item is reported." The Company believes its calculation to be a reliable estimate and allows it to properly take into account the usual elements that can impact its annualized book income and its impact on the effective tax rate. As such, the Company is computing its taxable income (loss) and associated income tax provision based on actual results through September 30, 2024.

ASC 740 also clarifies the accounting for uncertainty in income taxes recognized in an enterprise's financial statements and prescribes a recognition threshold and measurement process for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. ASC 740 also provides guidance on derecognition, classification, interest and penalties, accounting in interim period, disclosure and transition.

The Company recognizes accrued interest and penalties related to income taxes and unrecognized tax benefits as income tax expense. There were nounrecognized tax benefits as of September 30, 2024 and December 31, 2023. During the three and nine months ended September 30, 2024, the Company's provision for income taxes include a $3,224 true up for interest and penalties. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position.

The Company has identified the United States as its only "major" tax jurisdiction. The Company is subject to income taxation by major taxing authorities since inception. These examinations may include questioning the timing and amount of deductions, the nexus of income among various tax jurisdictions and compliance with federal and state tax laws. The Company's management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months.

Net (Loss) Income per Common Share

The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, "Earnings Per Share". Net (loss) income per common stock is computed by dividing net (loss) income by the weighted average number of common stock outstanding for the period. Accretion associated with the redeemable shares of Series A common stock is excluded from earnings per share as the redemption value approximates fair value.

The calculation of diluted (loss) income per share does not consider the effect of the warrants issued in connection with the (i) Initial Public Offering, and (ii) the private placement since the exercise of the warrants is contingent upon the occurrence of future events. The warrants are exercisable to purchase 28,850,000 Series A common stock in the aggregate. As of September 30, 2024 and 2023, the Company did not have any dilutive securities or other contracts that could, potentially, be exercised or converted into common stock and then share in the earnings of the Company. As a result, diluted net (loss) income per common stock is the same as basic net (loss) income per common stock for the periods presented.

The following table reflects the calculation of basic and diluted net (loss) income per common stock (in dollars, except per share amounts):

		For the Three Months Ended September 30,

Fair Value of Financial Instruments

The fair value of the Company's assets and liabilities, which qualify as financial instruments under ASC Topic 820, "Fair Value Measurement," approximates the carrying amounts represented in the accompanying unaudited condensed consolidated balance sheet, primarily due to their short-term nature.

Derivative Financial Instruments

The Company evaluated its financial statements to determine if such instruments are derivatives or contain features that qualify as embedded derivatives in accordance with FASB ASC Topic 815, "Derivatives and Hedging." For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at fair value on the grant date and re-valued at each reporting date, with changes in the fair value reported in the statements of operations. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is evaluated at the end of each reporting period. Derivative assets and liabilities are classified in the balance sheet as current or non-current based on whether or not net-cash settlement or conversion of the instruments could be required within 12 months of the balance sheet date. The Company accounted for the warrants issued in connection with the Initial Public Offering and the private placement as equity under the guidance at FASB ASC Topic 815.

Warrants

We account for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant's specific terms and applicable authoritative guidance in ASC 480 and ASC 815, "Derivatives and Hedging". The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to our own ordinary shares, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent reporting period date while the warrants are outstanding. Based on our assessment of the guidance, our warrants meet the criteria for equity classification and are recorded within stockholders' equity.

Share-based Compensation

The Company adopted ASC Topic 718, "Compensation-Stock Compensation," guidance to account for its share-based compensation. It defines a fair value-based method of accounting for an employee share option or similar equity instrument. The Company recognizes all forms of share-based payments, including share option grants, warrants and restricted share grants, at their fair value on the grant date, which are based on the estimated number of awards that are ultimately expected to vest. Share-based payments, excluding restricted shares, are valued using a Black-Scholes option pricing model. Grants of share-based payment awards issued to nonemployees for services rendered have been recorded at the fair value of the share-based payment, which is the more readily determinable value. The grants are amortized on a straight-line basis over the requisite service periods, which is generally the vesting period. If an award is granted, but vesting does not occur, any previously recognized compensation cost is reversed in the period related to the termination of service. Share-based compensation expenses are included in costs and operating expenses depending on the nature of the services provided in the statements of operations.

Recent Accounting Standards

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures ("ASU 2023-09"), which will require the Company to disclose specified additional information in its income tax rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. ASU 2023-09 will also require the Company to disaggregate its income taxes paid disclosure by federal, state and foreign taxes, with further disaggregation required for significant individual jurisdictions. ASU 2023-09 will become effective for Annual periods beginning after December 15, 2024. The adoption of ASU 2023-09 will not have a material impact on the Company's financial statements.

Management does not believe that any other recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company's financial statements.

NOTE 3. INITIAL PUBLIC OFFERING

Pursuant to the Initial Public Offering, the Company sold 30,000,000 Units, which include the partial exercise by the underwriters of their over-allotment option in the amount of 3,900,000 units, at a purchase price of $10.00 per Unit. Each Unit consists of one share of the Company's Series A common stock and one-half of one redeemable warrant ("Public Warrant"). Each Public Warrant entitles the holder to purchase one share of Series A common stock at an exercise price of $11.50 per whole share (see Note 7).

NOTE 4. PRIVATE PLACEMENT

Simultaneously with the closing of the Initial Public Offering, the Sponsor purchased an aggregate of 13,850,000 Private Placement Warrants at a price of $1.00 per Private Placement Warrant, for an aggregate purchase price of $13,850,000, in a private placement. Each Private Placement Warrant is exercisable to purchase one Series A common stock at a price of $11.50 per share, subject to adjustments (see Note 7). A portion of the proceeds from the Private Placement Warrants was added to the proceeds from the Initial Public Offering held in the Trust Account. If the Company does not complete a Business Combination within the Combination Period, the proceeds from the sale of the Private Placement Warrants will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law) and the Private Placement Warrants will expire worthless.

NOTE 5. RELATED PARTY TRANSACTIONS

Founder Shares

On October 25, 2021, the Sponsor paid $25,000 to cover certain offering costs of the Company in consideration for 7,187,500 shares of Series B common stock (the "Founder Shares"). On January 13, 2022, the Company effectuated a 1.044-for-1 stock split, resulting in an aggregate of 7,503,750 Founder Shares outstanding (see Note 7). Due to the underwriters' election to partially exercise their overallotment option, 3,750 shares were forfeited.

The Sponsor, founders, executive officers and directors have agreed, subject to certain limited exceptions, not to transfer, assign or sell any of the Founder Shares until one year after the completion of a Business Combination that results in all of the Company's stockholders having the right to exchange their Series A common stock for cash, securities, or other property (except with respect to permitted transferees). Notwithstanding the foregoing, (x) if the last reported sale price of the Series A common stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after a Business Combination, or (y) the date on which the Company completes a liquidation, merger, capital stock exchange or other similar transaction that results in all of the Company's stockholders having the right to exchange their shares of common stock for cash, securities or other property, then such securities will be released from these restrictions. Any permitted transferees would be subject to the same restrictions and other agreements of the founders with respect to any Founder Shares.

On October 25, 2021, the Sponsor transferred 250,000 Founder Shares to five director nominees (50,000 shares to each director nominee) for no consideration, to serve in his or her capacity as an independent director of the Company. The Company assigned the number of shares of Series B common stock of the Company, par value $0.0001 per share. The transfer of the Founders Shares to five director nominees is within the scope of FASB ASC Topic 718, "Compensation-Stock Compensation" ("ASC 718"). Under ASC 718, stock-based compensation associated with equity-classified awards is measured at fair value upon the grant date and expensed when earned. Shares granted to these directors are forfeited if their status as director is terminated for any reason prior to the date of a Business Combination and, as such, there has been no stock-based compensation expense recognized in the accompanying financial statements.

On December 1, 2021, the Company and Apeiron Investment Group Ltd. ("Apeiron") entered into an Agreement to which Apeiron will serve as an advisor to the Company in connection with identifying one or more businesses with which the Company may effectuate a Business Combination. As consideration for Apeiron's willingness to provide the service set forth in the Agreement, the Sponsor shall pay or transfer to Apeiron (or its designee) on behalf of the Company anon-refundable fee in the form of 50,000 shares of the Company's Series B common stock ("Fee Shares"). The transfer of the Founder Shares to Apeiron is not directly related to or in connection with the Initial Public Offering and not within the scope of offering costs as defined in Note 2. The transfer of the Fee Shares is in the scope of FASB ASC Topic 718, "Compensation-Stock Compensation" ("ASC 718"). Under ASC 718, stock-based compensation associated with equity-classified awards is measured at fair value upon the grant date. The fair value of the 50,000 Fee Shares granted to Apeiron was $362,500 or $7.25 per share. The Founders Shares were granted subject to a performance condition (i.e., the closing date of the Initial Public Offering). Compensation expense related to the Founders Shares is recognized only when the performance condition is probable of occurrence under the applicable accounting literature in this circumstance. As of December 31, 2022, the Company recognized $362,500 in the operations as stock-based compensation expense as the Company determined that the performance condition has been met at the date of issuance/closing of the Initial Public Offering.

On August 16, 2024, ACAB advanced Abpro $103,000 in connection with a promissory note ("August note") entered into between Abpro and Shahraab Ahmad on August 16, 2024 for expenses related to the Business Combination, whereas Shahraab Ahmad would receive repayment of $206,000. The August Note was cancelled and replaced with a promissory note to ACAB providing for the payment of $103,000 principal on the Closing Date.

Working Capital Loans

In order to finance transaction costs in connection with a Business Combination, the Sponsor has committed to advance the Company up to $1,750,000 to fund the expenses relating to investigating and selecting a target business and other working capital requirements after the Initial Public Offering and prior to a Business Combination. In addition, our Sponsor, or certain of our officers and directors or their affiliates may, but are not obligated to, loan us additional funds as may be required. If the Company consummated a Business Combination, the Company would repay the Working Capital Loans. In the event that a Business Combination does not close, the Company may use a portion of proceeds held outside the Trust Account to repay the Working Capital Loans, but no proceeds held in the Trust Account would be used to repay the Working Capital Loans. Up to $1,500,000 of such Working Capital Loans may be convertible into additional warrants of the post-Business Combination entity at a price of $1.00 per warrant at the option of the lender. The warrants would be identical to the Private Placement Warrants. Prior to the completion of the Business Combination, the Company does not expect to seek loans from parties other than the Sponsor or its affiliates as the Company does not believe third parties will be willing to loan such funds and provide a waiver against any and all rights to seek access to funds in the Trust Account. There are no Working Capital Loans outstanding as of September 30, 2024 and December 31, 2023.

Extension Promissory Notes - Related Party

On October 14, 2023 and November 14, 2023, the Company issued non-interest bearing, unsecured promissory notes in the principal amount of $80,000, respectively, (the "Extension Promissory Notes") to the Sponsor. The $80,000 of cash proceeds was deposited into the Company's trust account in order to extend the amount of time that the Company has available to complete a Business Combination. Upon the closing of a Business Combination by the Company, the Sponsor may elect to either receive repayment under the Notes or to convert all or a portion of the amount loaned under the Extension Promissory Notes into Series A common stock of the Company at a price equal to $10.20 per share. In the event that the Company does not complete a Business Combination, the amounts loaned under the Extension Promissory Notes will be repaid to the Sponsor only from funds held outside the Trust Account or will be forfeited, eliminated, or otherwise forgiven. As of September 30, 2024 and December 31, 2023, the Company owed $160,000 under the Extension Promissory Notes with no further borrowings available.

On December 18, 2023, the Company amended the Extension Promissory Notes to remove the Sponsors right to convert the note into Series A common stock at a price equal to $10.20 per share.

Expense Advancement Agreement

On May 30, 2024, the Company and the Sponsor entered into an expense advancement agreement (the "Expense Advancement Agreement"), pursuant to which the Sponsor has agreed to advance to the Company up to $600,000 in the aggregate, including previous amounts advanced from the Sponsor to the Company, on an interest-free basis as may be necessary to cover working capital expenses, fund certain redemptions of the Company's common stock and cover costs and expenses in connection with the consummation of the Company's proposed business combination with. Each advance under the Expense Advancement Agreement will be evidenced by a promissory note, the form of which is included as an exhibit to the Expense Advancement Agreement. This agreement replaces the previous Extension Promissory Notes in the aggregate amount of $160,000.

Holders of the Company's common stock are entitled to one vote for each share. At December 31, 2022, there were 7,500,000 shares of Series B common stock issued and outstanding, of which an aggregate of up to 978,500 shares were subject to forfeiture to the extent that the underwriters' over-allotment option was not exercised in full or in part so that the Initial Stockholders will own 20% of the Company's issued and outstanding common stock after the Initial Public Offering (assuming Initial Stockholders do not purchase any Public Shares in the Initial Public Offering). On January 13, 2022, the Company effectuated a 1.044-for-1 stock split, resulting in an aggregate of 7,503,750 Founder Shares outstanding. Due to the underwriters' election to partially exercise their overallotment option, 3,750 shares were forfeited, 1 Series B common stock are issued and outstanding at September 30, 2024 and December 31, 2023.

Holders of Series A common stock and Series B common stock will vote together as a single class on all other matters submitted to a vote of stockholders, except as required by law.

The shares of Series B common stock will automatically convert into shares of Series A common stock concurrently or immediately following the consummation of a Business Combination, on a one-for-one basis, subject to adjustment as provided herein. In the case that additional shares of Series A common stock, or equity-linked securities, are issued or deemed issued in connection with a Business Combination, the number of shares of Series A common stock issuable upon conversion of all Founder Shares will equal, in the aggregate, 20% of the total number of shares of Series A common stock outstanding after such conversion (after giving effect to any redemption of shares of Series A common stock by Public Stockholders), including the total number of shares of Series A common stock, or deemed issued or issuable upon conversion or exercise of any equity-linked securities or rights issued or deemed issued, by the Company in connection with or in relation to the consummation of a Business Combination, excluding any shares of Series A common stock or equity-linked securities exercisable for or convertible into shares of Series A common stock issued, or to be issued, to any seller in a Combination and any Private Placement Warrants issued to the Sponsor, officers, or directors upon conversion of Working Capital Loans, provided that such conversion of Founder Shares will never occur on a less than one-for-one basis.

Warrants -As of September 30, 2024 and December 31, 2023, there are 15,000,000 outstanding Public Warrants. Public Warrants may only be exercised for a whole number of shares. No fractional shares will be issued upon exercise of the Public Warrants. The Public Warrants will become exercisable on the later of (a) 30 days after the consummation of a Business Combination or (b) 12 months from the closing of the Initial Public Offering, provided in each case that there is an effective registration statement under the Securities Act covering the Series A common stock issuable upon exercise of the warrants and a current prospectus relating to them is available (or the Company permits holders to exercise their warrants on a cashless basis under the circumstances specified in the public warrant agreement) and such shares are registered, qualified, or exempt from registration under the securities, or blue sky, laws of the state of residence of the holder. The Public Warrants will expire five years from the consummation of a Business Combination or earlier upon redemption or liquidation.

The Company will not be obligated to deliver any Series A common stock pursuant to the exercise of a Public Warrant and will have no obligation to settle such Public Warrant exercise unless a registration statement under the Securities Act covering the issuance of the Series A common stock issuable upon exercise of the Public Warrants is then effective and a prospectus relating thereto is current, subject to the Company satisfying its obligations with respect to registration. No warrant will be exercisable, and the Company will not be obligated to issue shares of Series A common stock upon exercise of a warrant unless Series A common stock issuable upon such warrant exercise has been registered, qualified or deemed to be exempt under the securities laws of the state of residence of the registered holder of the warrants.

The Company has agreed that as soon as practicable, but in no event later than 20 business days after the closing of a Business Combination, it will use its commercially reasonable efforts to file with the SEC a registration statement covering the issuance, under the Securities Act, of the Series A common stock issuable upon exercise of the warrants. The Company will use its commercially reasonable efforts to cause the same to become effective within 60 business days after the closing of a Business Combination and to maintain the effectiveness of such registration statement, and a current prospectus relating thereto, until the expiration of the warrants in accordance with the provisions of the warrant agreement. If any such registration statement has not been declared effective by the 60th business day following the closing of a Business Combination, holders of the warrants will have the right, during the period beginning on the 61st business day after the closing of a Business Combination and ending upon such registration statement being declared effective by the SEC, and during any other period when the Company fails to have maintained an effective registration statement covering the issuance of the shares of Series A common stock issuable upon exercise of the warrants, to exercise such warrants on a "cashless basis." Notwithstanding the above, if the shares of Series A common stock are, at the time of any exercise of a warrant, not listed on a national securities exchange such that they satisfy the definition of a "covered security" under Section 18(b)(1) of the Securities Act, the Company may, at its option, require holders of Public Warrants who exercise their warrants to do so on a "cashless basis" in accordance with Section 3(a)(9) of the Securities Act and, in the event the Company so elect, the Company will not be required to file or maintain in effect a registration statement, but will use its commercially reasonable efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption is not available.

Once the warrants become exercisable, the Company may redeem the Public Warrants:

●	in whole and not in part;

●	at a price of $0.01 per warrant;

●	upon not less than 30 days' prior written notice of redemption given after the warrants become exercisable to each warrant holder; and

●

if, and only if, the reported last sale price of the Series A common stock equals or exceeds $18.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within a 30-trading day period commencing once the warrants become exercisable and ending three business days before the Company sends the notice of redemption to the warrant holders.

If and when the warrants become redeemable by the Company, the Company may exercise its redemption right even if it is unable to register or qualify the underlying securities for sale under all applicable state securities laws.

If the Company calls the Public Warrants for redemption, management will have the option to require all holders that wish to exercise the Public Warrants to do so on a "cashless basis," as described in the warrant agreement. The exercise price and number of shares of Series A common stock issuable upon exercise of the warrants may be adjusted in certain circumstances including in the event of a stock dividend, or recapitalization, reorganization, merger or consolidation. However, except as described below, the warrants will not be adjusted for issuance of Series A common stock at a price below its exercise price. Additionally, in no event will the Company be required to net cash settle the warrants. If the Company is unable to complete a Business Combination within the Combination Period and the Company liquidates the funds held in the Trust Account, holders of warrants will not receive any of such funds with respect to their warrants, nor will they receive any distribution from the Company's assets held outside of the Trust Account with the respect to such warrants. Accordingly, the warrants may expire worthless.

In addition, if (x) the Company issues additional shares of Series A common stock or equity-linked securities, for capital raising purposes in connection with the closing of a Business Combination at an issue price or effective issue price of less than $9.20 per share of Series A common stock (with such issue price or effective issue price to be determined in good faith by the Company's board of directors, and, in the case of any such issuance to the Sponsor or its affiliates, without taking into account any Founder Shares held by the Sponsor or its affiliates, as applicable, prior to such issuance) (the "Newly Issued Price"), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of a Business Combination on the date of the completion of a Business Combination (net of redemptions), and (z) the volume weighted average trading price of the Company's Series A common stock during the 20 trading day period starting on the trading day after the day on which the Company completes a Business Combination (such price, the "Market Value") is below $9.20 per share, the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the greater of the Market Value and the Newly Issued Price, and the $18.00 per share redemption trigger price will be adjusted (to the nearest cent) to be equal to 180% of the greater of the Market Value and the Newly Issued Price.

As of September 30, 2024 and December 31, 2023, there were 13,850,000 Private Placement Warrants, The Private Placement Warrants are identical to the Public Warrants underlying the Units sold in the Initial Public Offering, except that the Private Placement Warrants (including the Series A common stock issuable upon the exercise of the Private Placement Warrants) are not transferable, assignable or salable until 30 days after the completion of a Business Combination, subject to certain limited exceptions. Additionally, the Private Placement Warrants are exercisable on a cashless basis and are non-redeemable so long as they are held by the initial purchasers or their permitted transferees. If the Private Placement Warrants are held by someone other than the initial purchasers or their permitted transferees, the Private Placement Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants.

NOTE 8. FAIR VALUE MEASUREMENTS

The Company follows guidance in ASC 820 for its financial assets and liabilities that are re-measured and reported at fair value at each reporting period, and non-financial assets and liabilities that are re-measured and reported at fair value at least annually.

The fair value of the Company's financial assets and liabilities reflects management's estimate of amounts that the Company would have received in connection with the sale of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants at the measurement date. In connection the with measuring the fair value of its assets and liabilities, the Company seeks to maximize the use of observable inputs (market data obtained from independent sources) and to minimize the use of unobservable inputs (internal assumptions about how market participants would price assets and liabilities). The following fair value hierarchy is used to classify assets and liabilities based on the observable inputs and unobservable inputs used in order to value the assets and liabilities:

Level 1:

Quoted prices in active markets for identical assets or liabilities. An active market for an asset or liability is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis.

Level 2:

Observable inputs other than Level 1 inputs. Examples of Level 2 inputs include quoted prices in active markets for similar assets or liabilities and quoted prices for identical assets or liabilities in markets that are not active.

Level 3:

Unobservable inputs based on our assessment of the assumptions that market participants would use in pricing the asset or liability.

NOTE 9 - SUBSEQUENT EVENTS

The Company evaluated subsequent events and transactions that occurred after the balance sheet date up to the date that the unaudited condensed consolidated financial statements were issued.

On November 12, 2024, ACAB and Abpro completed the closing of the Business Combination of ACAB with Abpro Corporation, pursuant to the previously announced Business Combination Agreement, dated December 11, 2023, amended by an amendment dated September 4, 2024, by and among ACAB, Abpro Merger Sub Corp., a Delaware corporation and a wholly owned subsidiary of ACAB, and Abpro Corporation, following the approval at the special meeting of the shareholders of ACAB held on November 7, 2024. On November 12, 2024, pursuant to the BCA, and as described in greater detail in the Company's final prospectus and definitive proxy statement, which was filed with the SEC on October 18, 2024, Merger Sub merged with and into Abpro Corporation, with Abpro Corporation surviving the merger as a wholly owned subsidiary of ACAB, and ACAB changed its name to Abpro Holdings, Inc. As consideration for the Business Combination, New Abpro issued to or reserved for Abpro Corporation shareholders an aggregate of approximately 50,000,000 shares of New Abpro common stock, par value $0.0001 per share, consisting of 39,413,500 shares of Common Stock issued to Abpro Corporation shareholders, and 10,586,500 shares of Common Stock reserved for issuance in connection with certain Abpro Corporation rollover RSUs and stock options. In addition, New Abpro issued an aggregate of 3,367,401 shares of Common Stock to the PIPE investors (as described below), an aggregate of 1,250,000 shares of Common Stock to vendors in connection with the Closing, and Atlantic Coastal Acquisition Management II LLC forfeited and New Abpro cancelled 966,442 shares of Common Stock.

Under the Second Amended Articles of Incorporation of ACAB dated November 12, 2024, each of the outstanding shares of ACAB Series A Common Stock and the outstanding share of ACAB Class B Common Stock was exchanged into one share of Common Stock.

Unless otherwise defined herein, capitalized terms used in this Quarterly Report on Form 10-Q have the same meaning as set forth in the Proxy Statement/Prospectus.

In connection with the Special Meeting, ACAB shareholders holding 330,276 shares of ACAB's Series A common stock (the "Public Shares") (after giving effect to the share repurchases by Yorkville as described below) exercised their right to redeem their shares for a pro rata portion of the funds in ACAB's trust account. Prior to the Closing approximately $3,752,627 (approximately $11.36 per Public Share) was removed from the Trust Account to pay such holders.

Following the Closing, Abpro's stockholders shall be issued up to 14,500,000 additional shares of the Post- Combination Company common stock if, within five calendar years after the closing of the Business Combination, the volume weighted average price of shares of Series A Common Stock on Nasdaq, or any other national securities exchange on which the shares of Series A Common Stock are then traded ("VWAP") meets or exceeds three-tier target prices defined in the agreement, as follows:

a)	one-third of the total Earnout Shares, if, the VWAP is greater than or equal to $13.00 over any 20 trading days within any consecutive 30 trading day period (the "First Share Target")

b)	one-third of the total Earnout Shares, if, the VWAP is greater than or equal to $15.00 over any 20 trading days within any consecutive 30 trading day period (the "Second Share Target")

c)	one-third of the total Earnout Shares, if, the VWAP is greater than or equal to $18.00 over any 20 trading days within any consecutive 30 trading day period (the "Third Share Target").

These shares are contingently issuable upon the achievement of the set market performance targets. Considering the underlying contingent consideration to be transferred are common stocks, and as such is indexed to the Post-Combination Company's own stock and classified in stockholders' equity in the statement of financial position, we deemed the contingent payments under the earnout provisions to qualify for the scope exception in Accounting Standards Codification ("ASC") 815-10-15-74(a). As a result, the contingent consideration obligation will be recognized when the contingency is resolved, and the consideration is paid or becomes payable and has no impact on the pro forma condensed financial statements.

Abpro's 61,009 outstanding common stock warrants expired upon the consummation of the Business Combination.

Concurrently with the execution of the BCA, Abpro and Abpro Bio International, Inc., an Abpro stockholder, entered into an agreement, pursuant to which Sponsor agreed to, at the Closing Date, (i) retain 2,950,000 shares of Series A Common Stock of ACAB, (ii) retain 291,667 shares, and transfer 983,333 shares to Abpro and 983,333 of the shares Abpro Bio, for such parties to use to obtain non-redemption commitments from SPAC stockholders or other capital for SPAC or the Surviving Corporation (with any shares unused for such purpose to be retained by such party), and (iii) forfeit the remainder of any Series A Common Stock and Series B Common Stock held by Sponsor (or 966,441 Series A shares and 1 Series B shares).

If the 983,333 shares of Series A common stock held by Abpro and 291,667 shares held by the Sponsor are transferred to third-party investors in conjunction with their capital commitments, the maximum related costs to be recorded to additional paid-in capital will be in the amount of approximately $14.3 million (based on the fair value of ACAB's common stock shares of $11.20 per share at September 30, 2024) with the corresponding decrease in the paid-in-capital.

The Yorkville Note has a maturity of November 13, 2025, incurs interest at a rate of 0% (or 18% upon the occurrence of an uncured Event of Default), and is redeemable at the option of New Abpro if the VWAP of New Abpro's Common Stock is less than $11.50. Holder has a right to convert any portion of the Yorkville Note at any time at a conversion price equal to the lower of $11.50, 94% of the daily VWAP during the previous 5 consecutive trading days, which may be adjusted downward upon payment of stock dividend, stock split or reclassification, or if New Abpro issues Common Stock for no consideration or at a price lower than the then-effective Fixed Price (as defined in the Yorkville Note).

Overview

We are a blank check company incorporated in Delaware on May 20, 2021 for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization, or similar business combination with one or more businesses. We may pursue a Business Combination target in any industry or sector, but given the experience of our management team, we expect to focus on acquiring a business combination target within the financial services industry and related sectors, including potentially the mobility sector. We intend to effectuate our Business Combination using cash from the proceeds of the Initial Public Offering and the sale of the Private Placement Warrants, our capital stock, debt or a combination of cash, stock and debt.

On November 12, 2024, ACAB and Abpro completed the closing of the Business Combination of ACAB with Abpro Corporation, pursuant to the previously announced Business Combination Agreement, dated December 11, 2023, amended by an amendment dated September 4, 2024, by and among ACAB, Abpro Merger Sub Corp., a Delaware corporation and a wholly owned subsidiary of ACAB, and Abpro Corporation, following the approval at the special meeting of the shareholders of ACAB held on November 7, 2024.

Results of Operations

We have neither engaged in any operations nor generated any revenues to date. Our only activities from May 20, 2021 (inception) through September 30, 2024 were organizational activities, those necessary to consummate the Initial Public Offering, described below, and identifying a target company for a Business Combination. We do not expect to generate any operating revenues until after the completion of our Business Combination. We generate non-operating income in the form of interest income on cash and marketable securities held in the Trust Account. We incur expenses as a result of being a public company (for legal, financial reporting, accounting and auditing compliance), as well as for due diligence expenses.

For the three months ended September 30, 2024, we had a net loss of $335,100, which consisted of operating and formation costs of $391,686 and provision for income taxes of $27,654 partially offset by interest income from bank of $2,078 and interest earned on cash and marketable securities held in the Trust Account of $82,162.

For the three months ended September 30, 2023, we had a net loss of $44,630 which consists operating and formation costs of $315,247, interest and penalties on tax obligations of $127,646 and provision for income taxes of $96,005, partially offset by interest income from bank of $25,961 and interest earned on marketable securities held in the Trust Account of $468,307.

For the nine months ended September 30, 2024, we had a net loss of $1,722,675 which consisted of operating and formation costs of $1,926,428 and provision for income taxes of $57,967, partially offset by interest income from bank of $2,964 and interest earned on cash and marketable securities held in the Trust Account of $258,756.

For the nine months ended September 30, 2023, we had a net income of $2,828,701 which consists of interest earned on marketable securities held in the Trust Account of $5,279,395 and interest income from bank of $43,744, partially offset by operating and formation costs of $1,273,146, provision for income taxes of $1,093,646 and interest and penalties on tax obligation of $127,646.

Liquidity and Capital Resources

On January 19, 2022, we consummated our Initial Public Offering of 30,000,000 Units, which includes the partial exercise by the underwriters of its over-allotment option in the amount of 3,900,000 Units at $10.00 per Unit, generating gross proceeds of $300,000,000. Simultaneously with the closing of our Initial Public Offering, we consummated the sale of 13,850,000 Private Placement Warrants at a price of $1.00 per Private Placement Warrant in a private placement to the Sponsor, generating gross proceeds of $13,850,000.

Transaction costs amounted to $17,204,107 consisting of $5,760,000 of underwriting discount (net of $240,000 reimbursed by the underwriters), $10,500,000 of deferred underwriting fees, and $944,107 of other offering costs. We have agreed to pay a deferred underwriting fee to the underwriters upon the consummation of a Business Combination in an amount equal to, in the aggregate, 3.5% of the gross proceeds of the Initial Public Offering or an aggregate of $10,500,000.

The Company and the underwriters have agreed the underwriters will be entitled to 600,000 shares of common stock in deferred underwriting fees contingent on completion of the Merger.

The promissory note issued in connection with unsecured loans from our Sponsor to finance our liquidity needs through the consummation of our Initial Public Offering was non-interest bearing and the aggregate amount of $149,539 outstanding under the promissory note as of January 19, 2022 was fully repaid on February 22, 2022.

Following the Initial Public Offering, the partial exercise of the over-allotment option, and the sale of Private Placement Warrants, a total of $306,000,000 was placed in the Trust Account. We incurred $17,204,107 in Initial Public Offering related costs, including $5,760,000 of underwriting fees and $944,107 of other costs. On April 18, 2023, the company held the Meeting and as a result 26,564,308 shares of the Company's Series A common stock were redeemed at approximately $10.41 per share. On December 13, 2023, stockholders holding a total of 2,768,301 public shares of Series A common stock exercised and did not reverse, their right to redeem their public shares in connection with the vote upon the Charter Amendment Proposal. As a result of the foregoing, those holders will receive a payment of approximately $10.68 per share redeemed.

As of September 30, 2024, we had cash held in the Trust Account of $7,721,206 ($29,728,990 was redeemed and withdrawn in January 2024). Interest income on the balance in the Trust Account may be used by us to pay taxes. Through September 30, 2024, we have withdrawn an amount of $308,332,719 which consists of $306,200,450 attributable to redemptions and $2,132,269 attributable to withdrawals to pay tax obligations.

To mitigate the risk of us being deemed to have been operating as an unregistered investment company (including under the subjective test of Section 3(a)(1)(A) of the Investment Company Act), the Company instructed the Trustee in December 29, 2023 to liquidate the U.S. government securities or money market funds held in the Trust Account and thereafter to hold all funds in the Trust Account in cash (which may include demand deposit accounts) until the earlier of consummation of a Business Combination or liquidation.

As of September 30, 2024, we had cash of $13,597. We intend to use the funds held outside the Trust Account primarily to identify and evaluate target businesses, perform business due diligence on prospective target businesses, travel to and from the offices, plants or similar locations of prospective target businesses or their representatives or owners, review corporate documents and material agreements of prospective target businesses, and structure, negotiate and complete a Business Combination.

In order to fund working capital deficiencies or finance transaction costs in connection with a Business Combination, our Sponsor has committed to provide us $1,750,000 to fund our expenses relating to investigating and selecting a target business and other working capital requirements. In addition, our Sponsor, or certain of our officers and directors or their affiliates may, but are not obligated to, loan us additional funds as may be required. If we complete a Business Combination, we would repay such loaned amounts. In the event that a Business Combination does not close, we may use a portion of the working capital held outside the Trust Account to repay such loaned amounts but no proceeds from our Trust Account would be used for such repayment. Up to $1,500,000 of such Working Capital Loans may be convertible into warrants of the post-Business Combination entity at a price of $1.00 per warrant. The warrants would be identical to the Private Placement Warrants.

On October 14, 2023 and November 14, 2023, the Company issued the Extension Promissory Notes to the Sponsor. The $80,000 of cash proceeds was deposited into the Company's trust account in order to extend the amount of time that the Company has available to complete a Business Combination. Upon the closing of a Business Combination by the Company, the Sponsor may elect to either receive repayment under the Extension Promissory Notes or to convert all or a portion of the amount loaned under the Extension Promissory Notes into Series A common stock of the Company at a price equal to $10.20 per share. In the event that the Company does not complete a Business Combination, the amounts loaned under the Extension Promissory Notes will be repaid to the Sponsor only from funds held outside the Trust Account or will be forfeited, eliminated, or otherwise forgiven. As of September 30, 2024 and December 31, 2023, the Company owed $160,000 due under the Extension Promissory Notes with no further borrowings available.

On December 18, 2023, the Company amended the Extension Promissory Notes to remove the Sponsors right to convert the note into Series A common stock at a price equal to $10.20 per share.

As of September 30, 2024 and December 31, 2023, the Sponsor advanced the Company $2,270,051 and $1,655,000, respectively, and is reflected in the unaudited condensed consolidated balance sheets.

For the nine months ended September 30, 2024, cash used in operating activities was $775,992. Net loss of $1,722,675 was affected by interest earned on cash and marketable securities held in the Trust Account of $258,756. Changes in operating assets and liabilities provided $1,205,439 of cash for operating activities.

For the nine months ended September 30, 2023, cash used in operating activities was $1,506,562. Net income of $2,828,701 was affected by interest earned on marketable securities held in the Trust Account of $5,279,395. Changes in operating assets and liabilities provided $944,132 of cash for operating activities.

Going Concern

In connection with the Company's assessment of going concern considerations in accordance with the Financial Accounting Standards Board's ("FASB") Accounting Standards Codification ("ASC") Topic 205-40 "Presentation of Financial Statements-Going Concern," management has determined the future viability of the Company is largely dependent on its ability to raise additional capital to finance its operations. The Company expects to seek additional funding through equity and debt financings, collaboration agreements and research grants. Although the Company has been successful in raising capital in the past, there is no assurance that it will be successful in obtaining such additional financing on terms acceptable to the Company, if at all. If the Company is unable to obtain funding, the Company could be forced to delay, reduce or eliminate its research and development programs, product portfolio expansion or commercialization efforts, which could adversely affect its business prospects.

Accordingly, based on the considerations discussed above, management has concluded there is substantial doubt as to the Company's ability to continue as a going concern within one year after the date the condensed consolidated financial statements are issued. If adequate funds are not available, the Company may require initiating steps to slow cash burn, extending the cash runway until financing can be secured. The unaudited condensed consolidated financial statements do not include any adjustments with respect to the carrying amounts of assets and liabilities and their classification that might result from the outcome of this uncertainty.

Off-Balance Sheet Financing Arrangements

We have no obligations, assets or liabilities, which would be considered off-balance sheet arrangements as of September 30, 2024. We do not participate in transactions that create relationships with unconsolidated entities or financial partnerships, often referred to as variable interest entities, which would have been established for the purpose of facilitating off-balance sheet arrangements. We have not entered into any off-balance sheet financing arrangements, established any special purpose entities, guaranteed any debt or commitments of other entities, or purchased any non-financial assets.

Contractual Obligations

We do not have any long-term debt, capital lease obligations, operating lease obligations or long-term liabilities, other than the following:

The underwriters were entitled to a cash underwriting discount of $0.20 per Unit, or $6,000,000 in the aggregate, paid on the closing of the Initial Public Offering. In addition, the underwriters are entitled to a deferred fee of $0.35 per Unit, or $10,500,000 in the aggregate. The deferred fee will become payable to the underwriter from the amounts held in the Trust Account solely in the event that we complete a Business Combination, subject to the terms of the underwriting agreement. The Company and the underwriters have agreed the underwriters will be entitled to 600,000 shares of common stock in deferred underwriting fees contingent on completion of the Merger.

Critical Accounting Policies

The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements, and income and expenses during the periods reported. We have identified the following critical accounting policies:

Common Stock Subject to Possible Redemption

We account for our common stock subject to possible conversion in accordance with the guidance in ASC Topic 480, "Distinguishing Liabilities from Equity." Common stock subject to mandatory redemption is classified as a liability instrument and measured at fair value. Conditionally redeemable common stock (including common stock that features redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within our control) is classified as temporary equity. At all other times, common stock is classified as a component of stockholders' equity. Our common stock features certain redemption rights that are considered to be outside of our control and subject to occurrence of uncertain future events. Accordingly, common stock subject to possible redemption is presented at redemption value as temporary equity outside of the stockholders' equity section of our balance sheets.

Warrants

We account for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant's specific terms and applicable authoritative guidance in ASC 480 and ASC 815, "Derivatives and Hedging". The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to our own ordinary shares, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent reporting period date while the warrants are outstanding. Based on our assessment of the guidance, our warrants meet the criteria for equity classification and are recorded within stockholders' deficit.

Net (Loss) Income Per Common Share

Net (loss) income per common stock is computed by dividing net (loss) income by the weighted average number of common stock outstanding for the period. Accretion associated with the redeemable shares of Series A common stock is excluded from earnings per share as the redemption value approximates fair value.

Recent Accounting Standards

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures ("ASU 2023-09"), which will require the Company to disclose specified additional information in its income tax rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. ASU 2023-09 will also require the Company to disaggregate its income taxes paid disclosure by federal, state and foreign taxes, with further disaggregation required for significant individual jurisdictions. ASU 2023-09 will become effective for Annual periods beginning after December 15, 2024. The Company is still reviewing the impact of ASU 2023-09.

Management does not believe that any other recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on our financial statements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Not required for smaller reporting companies.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures are designed to ensure that information required to be disclosed by us in our Exchange Act reports is recorded, processed, summarized, and reported within the time periods specified in the SEC's rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Under the supervision and with the participation of our management, including our principal executive officer and principal financial and accounting officer, we conducted an evaluation of the effectiveness of our disclosure controls and procedures as of the end of the fiscal quarter ended September 30, 2024, as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based on this evaluation, our principal executive officer and principal financial and accounting officer have concluded that during the period covered by this report, our disclosure controls and procedures were not effective as of September 30, 2024 due to the Company not filing timely tax returns and utilizing cash withdrawn from the trust account for tax obligations for operating purposes.

We do not expect that our disclosure controls and procedures will prevent all errors and all instances of fraud. Disclosure controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the disclosure controls and procedures are met. Further, the design of disclosure controls and procedures must reflect the fact that there are resource constraints, and the benefits must be considered relative to their costs. Because of the inherent limitations in all disclosure controls and procedures, no evaluation of disclosure controls and procedures can provide absolute assurance that we have detected all our control deficiencies and instances of fraud, if any. The design of disclosure controls and procedures also is based partly on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting that occurred during the fiscal quarter of 2024 covered by this Quarterly Report on Form 10-Q that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II-OTHER INFORMATION

Item 1. Legal Proceedings

None

Item 1A. Risk Factors

We have identified ineffective disclosure controls and procedures that, if unsuccessfully remediated, could adversely affect our ability to report our financial results on a timely and accurate basis and to consummate an initial business combination.

Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our disclosure controls and procedures. Based on such evaluation, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures were not effective as of September 30, 2024 due to the Company not filing timely tax returns and utilizing cash withdrawn from the Trust Account for tax obligations for operating purposes. Failure to achieve and maintain effective disclosure controls and procedures could adversely affect our ability to report our financial results on a timely and accurate basis and to consummate an initial business combination. We may also identify material weaknesses or other deficiencies in our disclosure controls and procedures in the future. Any material weaknesses or other deficiencies in our control systems may affect our ability to comply with SEC reporting requirements and listing standards or cause our financial statements to contain material misstatements which could negatively affect market price and trading liquidity of our common stock.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

On October 25, 2021, we issued 7,187,500 shares of our Series B common stock, to our Sponsor for $25,000 in cash, at a purchase price of approximately $0.035 per share (or $0.0033 per share, after giving effect to a 1.044-for-1 stock split on January 13, 2022), in connection with our formation. Such shares were issued in connection with our organization pursuant to the exemption from registration contained in Section 4(a)(2) of the Securities Act. On January 13, 2022, we effectuated a 1.044-for-1 stock split, resulting in an aggregate of 7,503,750 Founder Shares outstanding and held by our Initial Stockholders. On January 18, 2022, the underwriters partially exercised their over-allotment option and the remaining unexercised portion of over-allotment option were forfeited, an aggregate of 3,750 Founder Shares were forfeited, resulting in an aggregate of 7,500,000 Founder Shares outstanding held by our Initial Stockholders.

On January 13, 2022, we consummated the Initial Public Offering of 30,000,000 Units. Each Unit consists of one share of Series A common stock and one-half of a redeemable warrant, each warrant entitling the holder thereof to purchase one share of Series A common stock for $11.50 per share. The Units were sold at an offering price of $10.00 per unit, generating total gross proceeds of $300,000,000. Cantor Fitzgerald & Co. acted as sole book-running manager. The securities sold in the Initial Public Offering were registered under the Securities Act on a Registration Statement on Form S-1 (No. 333-261459), which was declared effective by the SEC on January 13, 2022.

Simultaneously with the closing of our Initial Public Offering, we consummated a Private Placement of 13,850,000 private placement warrants, at a price of $1.00 per Private Placement Warrant, to our Sponsor, generating gross proceeds of $13,850,000. Such securities were issued pursuant to the exemption from registration contained in Section 4(a)(2) of the Securities Act.

Following the closing of our Initial Public Offering and the sale of the Private Placement Warrants, an aggregate amount of $306,000,000 ($10.20 per unit) was placed in a Trust Account.

Transaction costs amounted to $17,204,107, consisting of $5,760,000 in underwriting discount (net of $240,000 reimbursed by the underwriters), $10,500,000 in deferred underwriting discount and $944,107 of other offering costs. In addition, $1,819,051 of cash is held outside of the Trust Account and is available for the payment of offering costs and for working capital purposes as of the Initial Public Offering date.
