[Form 3/A] American Exceptionalism Acquisition Corp. A Amended Initial Statement of Beneficial Ownership

Rhea-AI Filing Summary

American Exceptionalism Acquisition Corp. A filed an amended initial ownership report showing sponsor-related holdings in the company’s shares. The filing reports derivative ownership of 12,021,429 Class A ordinary shares underlying Class B founder shares held in the name of AEXA Sponsor LLC, which is managed by Chamath Palihapitiya. These Class B shares automatically convert into Class A shares on a one-for-one basis upon certain share price or change-of-control conditions after the company’s initial business combination, and 1,607,143 of the Class B shares are subject to forfeiture if the underwriters do not fully exercise their over-allotment option. The amendment clarifies that SC SPAC Holdings LLC is now identified with its own CIK as a reporting owner, with no change to its beneficial ownership.

Explanation of Responses:

1. As described in the Issuer's Registration Statement on Form S-1, as amended (File No. 333-289701), under the heading "Description of Securities - Founder Shares," Class B ordinary shares will automatically convert into Class A ordinary shares on or prior to the tenth anniversary of the Issuer's initial business combination, upon the earlier of (A) the Issuer meeting certain share price performance thresholds following the completion of its initial business combination, and (B) subsequent to the completion of its initial business combination, the date on which a change of control occurs, in each case, on a one-for-one basis, subject to adjustment as provided therein. Includes 1,607,143 Class B ordinary shares that are subject to forfeiture if the underwriters of the Issuer's initial public offering do not exercise in full their option to purchase additional Class A ordinary shares.

Remarks:

On the basis of the relationship between the Sponsor, SC SPAC Holdings and Mr. Palihapitiya, the Sponsor and SC SPAC Holdings will be deemed directors by deputization. 2. The reporting owner, AEXA Sponsor LLC (the "Sponsor"), in whose name the securities reported herein are held, is managed by its manager, Chamath Palihapitiya. A majority of the voting interests of the Sponsor are held by SC SPAC Holdings LLC ("SC SPAC Holdings"), which is controlled by Mr. Palihapitiya. Mr. Palihapitiya and SC SPAC Holdings may be deemed to beneficially own shares held by the Sponsor by virtue of their direct or indirect interests in the Sponsor or their shared control over the Sponsor, as the case may be. Each of Mr. Palihapitiya and SC SPAC Holdings disclaims beneficial ownership of the shares held by the Sponsor, except to the extent of such person's pecuniary interest therein. This Form 3/A amends the original Form 3 filed on September 25, 2025, which reported SC SPAC Holdings LLC's initial holdings using the Issuer's CIK as an interim measure, pending receipt of SC SPAC Holdings LLC's personal CIK codes. This Form 3/A now utilizes SC SPAC Holdings LLC's personal CIK codes, identifying it as the Reporting Owner, with no alteration to its beneficial ownership.
