The sponsor

ST Sponsor II Limited.

Charlton Aria Acquisition Corporation is sponsored by ST Sponsor II Limited, an exempted company incorporated in the Cayman Islands. ST Sponsor II Limited became wholly owned by Sovereign Global Trust LLC, a Delaware limited liability company, on May 13, 2025. The sponsor holds the company's founder shares and private placement units, and is responsible for the search, diligence, and structuring of the company's initial business combination on behalf of public shareholders.

Role of the sponsor

A committed private vehicle behind a public listing.

ST Sponsor II Limited was organized in 2024 to sponsor a special purpose acquisition company. As sponsor, it underwrites the formation, marketing, and operating costs of the SPAC prior to a business combination, including the private placement that funds working capital, professional fees, and the over-allotment portion of the trust.

The sponsor's economic alignment with public shareholders is structural: the founder shares and private placement units held by the sponsor have no realizable value if the company does not consummate a qualifying business combination within the prescribed combination period. This creates a direct incentive to deliver a transaction of genuine quality, not merely to deliver a transaction.

Day-to-day work of the sponsor — sourcing, evaluating, and structuring potential targets — is conducted by the sponsor's directors and advisors, in coordination with the company's officers and board.

Sponsor structure

The particulars.

Legal entity

ST Sponsor II Limited, an exempted company incorporated under the laws of the Cayman Islands. Memorandum and Articles of Association adopted March 22, 2024.

Ownership

Wholly owned by Sovereign Global Trust LLC, a Delaware limited liability company, following the closing of a share purchase agreement on May 13, 2025. Sovereign Global Trust LLC is the sole director and shareholder of the sponsor.

Securities held

Founder shares (Class B ordinary shares) and private placement units acquired in a private placement that closed concurrently with the company's initial public offering.

Risk capital

Sponsor funds at risk include the purchase price of founder shares and private placement units, working capital advances, and out-of-pocket expenses associated with sourcing and evaluating potential business combinations.

Alignment

Why structure matters.

The sponsor model is most useful when it produces tight alignment between the people sourcing a transaction and the public shareholders who will own the resulting public company.

Skin in the game

The sponsor's investment in founder shares and private placement units is at risk through the date of any business combination. If no qualifying combination occurs, those securities have no realizable value.

Aligned timing

The sponsor cannot recover its investment by liquidating prior to a business combination. Returns are only available when public shareholders also receive value through a closed transaction.

Lock-up commitments

Founder shares and private placement units are subject to customary lock-up arrangements following a business combination, ensuring continued sponsor exposure to the combined company's performance.
