During the past five years, neither the Sponsor nor Mr. Nash has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors).

Each of the Sponsor and Mr. Nash has not, during the last five years, been a party to civil proceeding of a judicial administrative body of competent jurisdiction and, as a result of such proceeding, was, or are subject to, a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, Federal or state securities laws or finding any violation with respect to such laws.

Sponsor is a Delaware limited liability company. Mr. Nash is a citizen of the United States.

The source of the funds used by the reporting persons to acquire the ordinary shares reported on in this Amendment No. 2 to Schedule 13D (the "Schedule 13D") was working capital of the Sponsor. See also Item 4 of this Schedule 13D, which information is incorporated herein by reference.

On August 7, 2025, the Sponsor paid $25,000, or approximately $0.003 per share, to cover certain of the Issuer's offering costs in exchange for 7,665,900 Class B ordinary shares (the "Founder Shares"), of which up to 999,900 founder shares were subject to forfeiture depending on the extent to which the underwriters' over-allotment option was exercised, pursuant to the Securities Subscription Agreement dated as of August 7, 2025 between the Sponsor and the Issuer (the "Founder Share Purchase Agreement"). On December 24, 2025, the Issuer consummated its initial public offering ("IPO") and in connection with the consummation, Sponsor purchased an aggregate of 425,000 private placement units for an aggregate purchase price of $4,250,000. Each unit purchased was comprised of one Class A ordinary share of the Issuer and one-half of one redeemable warrant of the Issuer upon consummation of an initial business combination (as described more fully in the Issuer's Final Prospectus). On January 7, 2026, Clear Street LLC, the representative of the underwriters, partially exercised the underwriters' overallotment option. As a result, 499,950 Class B ordinary shares were forfeited by the Sponsor to the Issuer at no cost in connection with the expiration of the remaining portion of the underwriters' over-allotment option on February 6, 2026. On September 17, 2026, the Issuer, EigenQ, Inc. ("EigenQ") and an institutional investor (the "Investor") entered into that certain Securities Purchase Agreement (the "SPA"), in connection with a note financing (the "Note Financing"), as described in the Issuer's Current Report on Form 8-K, filed with the SEC on September 18, 2026. In connection with the Note Financing, the Issuer, the Sponsor and the Investor, entered into a founder shares transfer agreement (the "Founder Shares Transfer Agreement"), dated as of September 17, 2026, pursuant to which, the Sponsor agreed to transfer up to 1,000,000 Class B ordinary shares to the Investor, with 500,000 shares to be transferred as of the Initial Closing and 500,000 shares to be transferred as of the Additional Closing (each as defined in the SPA). The Class B ordinary shares transferred to the Investor shall continue to be subject to lock-up and transfer restrictions as provided in the Insider Letter (as defined below), until the consummation of the Issuer's business combination with EigenQ (the "Business Combination"), and shall be registered in the Form S-4 to be filed in connection with the Business Combination registration statement and be freely tradable after consummation of the Business Combination. Upon the Initial Closing on September 17, 2026, the Sponsor transferred 500,000 Class B ordinary shares to the Investor. This Schedule 13D does not take into consideration the 500,000 Class B ordinary shares which will become transferable upon the Additional Closing, subject to the terms and conditions of the SPA and Founder Shares Transfer Agreement. The reporting persons made the acquisitions reported in this Schedule 13D in support of the Issuer's business plan and for investment purposes. The reporting persons may acquire or dispose of additional securities or sell securities of the Issuer from time to time in the market or in private transactions, including as a result of ownership of the warrants referred to above. However, reporting persons do not have any other agreements to acquire additional ordinary shares at this time. As Chief Executive Officer of the Issuer, Mr. Nash is involved in making material business decisions regarding the Issuer's policies and practices and may be involved in the consideration of various proposals considered by the Issuer's board of directors. Additionally, as the Issuer's business plan is to enter into a business combination, Mr. Nash, as Chief Executive Officer of the Issuer, is actively involved in pursuing a suitable target for the Issuer's business combination and will be actively involved in effecting any such business combination if the Issuer's business plan is successful, which may also result in a change in the Issuer's board of directors, corporate structure or charter. As of the date of this Schedule 13D, except as set forth in this Schedule 13D above, the reporting persons do not have any plans or proposals which would result in: (a) The acquisition by any person of additional securities of the Issuer, or the disposition of securities of the Issuer; (b) An extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Issuer or any of its subsidiaries; (c) A sale or transfer of a material amount of assets of the Issuer or any of its subsidiaries; (d) Any change in the present board of directors or management of the Issuer, including any plans or proposals to change the number or term of the board of directors or management of the Issuer; (e) Any material change in the present capitalization or dividend policy of the Issuer; (f) Any other material change in the Issuer's business or corporate structure; (g) Changes in the Issuer's charter, bylaws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Issuer by any person; (h) Causing a class of securities of the Issuer to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association; (i) A class of equity securities of the Issuer becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Act; or (j) Any action similar to any of those actions enumerated above.

The aggregate number and percentage of Class A ordinary shares beneficially owned by reporting persons (on the basis of a total of 29,320,950 ordinary shares outstanding as of August 14, 2026) are as follows: i. Sponsor: 7,090,950 Class A ordinary shares; 24.2% ii. Dan Nash: 7,090,950 Class A ordinary shares; 24.2%

Number of shares to which Sponsor has: i. Sole power to vote or to direct the vote: 7,090,950, ii. Shared power to vote or to direct the vote: 0, iii. Sole power to dispose or to direct the disposition of: 7,090,950, and iv. Shared power to dispose or to direct the disposition of: 0. Number of shares to which Dan Nash has: i. Sole power to vote or to direct the vote: 7,090,950, ii. Shared power to vote or to direct the vote: 0, iii. Sole power to dispose or to direct the disposition of: 7,090,950, and iv. Shared power to dispose or to direct the disposition of: 0. Mr. Nash is the manager of the Sponsor. Therefore, Mr. Nash may be deemed to beneficially own the 425,000 Class A ordinary shares and 6,665,950 Class B ordinary shares, and ultimately exercise voting and dispositive power over the Class A ordinary shares and Class B ordinary shares held by the Sponsor. Mr. Nash disclaims any beneficial ownership of the securities held by the Sponsor other than to the extent of any pecuniary interest he may have therein, directly or indirectly.
