Commitments and Contingencies [Abstract]

Note 6 — Commitments and Contingencies

Litigation

From time to time, the Company may become involved in various lawsuits and legal proceedings, which arise in the ordinary course of business. However, litigation is subject to inherent uncertainties, and an adverse result in these or other matters may arise from time to time that may harm the Company’s business. The Company is not aware of any such legal proceedings that will have, individually or in the aggregate, a material adverse effect on its business, financial condition or operating results.

Contingently Issuable Private Placement Warrants

In connection with the consummation of the transactions contemplated by the Securities Purchase Agreement, CB Co-Investment irrevocably agreed to convert the Conversion Amount by CB Co-Investment to the Company at a conversion price of $1.00 per warrant, or 1,150,000 warrants upon consummation of a Business Combination. Upon consummation of a Business Combination, 805,000, 273,431 and 71,569 of the contingently issuable Private Placement Warrants will be issued to Fulton AC, CBG and CB Co-Investment, respectively.

Registration Rights and Shareholder Rights

The holders of the Class B ordinary shares, Private Placement Warrants, Class A ordinary shares underlying the Private Placement Warrants, the Forward Purchase Securities and warrants that may be issued upon conversion of the Convertible Note and the Working Capital Loans (and any Class A ordinary shares issuable upon the exercise of the Private Placement Warrants, Forward Purchase Warrants and warrants that may be issued upon conversion of such loans) were entitled to registration rights pursuant to a registration and shareholder rights agreement signed upon the effective date of the Initial Public Offering. The Forward Purchase Securities were terminated on December 29, 2023. The holders of these securities are entitled to make up to three demands, excluding short form demands, that the Company registers such securities. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to the completion of the initial Business Combination. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

Business Combination Marketing Agreement

On November 9, 2021, the Company entered into an agreement with one of the underwriters in its Initial Public Offering, Cowen and Company, LLC, as advisors in connection with the Company’s Business Combination to assist the Company in holding meetings with the shareholders to discuss the potential Business Combination and the target business’ attributes, introduce the Company to potential investors that are interested in purchasing the Company’s securities in connection with the potential Business Combination, assist the Company in obtaining shareholder approval for the Business Combination and assist the Company with its press releases and public filings in connection with the Business Combination. The Company agreed to pay a fee for such services (the “Marketing Fee”) upon the consummation of the initial Business Combination in an amount equal to, in the aggregate, 3.5% of the gross proceeds of the Initial Public Offering, or approximately $8.1 million in the aggregate. The Marketing Fee was waived by Cowen as of December 29, 2023.

Forward Purchase Agreement

The Forward Purchase Agreement provided for the purchase by Franklin, in the aggregate, of 6,000,000 Forward Purchase Securities, for an aggregate purchase price of $40.0 million, with each Forward Purchase Security consisting of one Class A ordinary share and one-half of one redeemable warrant in each case, for an aggregate of 4,000,000 Class A ordinary shares and 2,000,000 redeemable warrants, for $10.00 per Forward Purchase Security, in a private placement to close substantially concurrently with the closing of the initial Business Combination. Effective as of the Closing Date, in connection with the Securities Purchase Agreement, the Company and Franklin entered into a Letter Agreement terminating the Forward Purchase Agreement.

Non-Redemptions Agreements

As discussed more fully in Note 1, in exchange for the commitments not to redeem certain Class A ordinary shares in connection with the Special Meeting, CBG and CB Co-Investment agreed to transfer an aggregate of 1,000,000 ordinary shares of the Company held by CBG or CB Co-Investment, as applicable, plus up to an additional aggregate of 500,000 ordinary shares of the Company held by CBG or CB Co-Investment, with such number of additional ordinary shares of the Company to be determined based upon the date of the consummation of the Company’s initial Business Combination.

The Company estimated the aggregate fair value of a weighted number of Class B ordinary shares, based on the likelihood of consummating an initial Business Combination beyond November 15, 2023, or 1,166,663 Class B ordinary shares, attributable to the non-redeeming shareholder be $4,802,931 or $4.12 per share. Each non-redeeming shareholder acquired from CBG an indirect economic interest in the Class B ordinary shares. The excess of the fair value of the Class B ordinary shares was determined to be an offering cost in accordance with the SEC Staff Accounting Bulletin (“SAB”) Topic 5A – Expenses of Offering. Accordingly, in substance, it was recognized by the Company as a capital contribution by CBG to induce these holders of the Class A ordinary shares not to redeem, with a corresponding charge to additional paid-in capital to recognize the fair value of the shares transferred as an offering cost.

The Note may be prepaid at any time without penalty.
