Constellation Acquisition Corp I (OTC: CSTAF) is a blank-check special purpose acquisition company (SPAC) incorporated under Cayman Islands law that was formed to identify and complete a merger or similar business combination with a target company. It does not operate a commercial business and generates no operating revenue. Capital raised at IPO is held in a Trust Account pending consummation of a Business Combination. As of the 10-K filed April 15, 2026, the company had signed a Business Combination Agreement dated April 9, 2026, with HiTech as the target, structured through a PubCo and two merger subsidiaries. The company faces a mandatory liquidation and dissolution deadline of April 29, 2026 (extendable to no later than January 29, 2027) if a Business Combination is not completed. The filing discloses substantial doubt about the company's ability to continue as a going concern through that deadline. Constellation Sponsor LP is the affiliated sponsor entity and a related-party lender via promissory notes.

Revenue model

No operating revenue. The company holds IPO proceeds in a Trust Account invested until a Business Combination is closed or shareholders are redeemed. The economic model is purely transactional: the sponsor and founders earn promote shares contingent on completing an acquisition.

Products and services

Blank-check SPAC vehicle. Key instruments include Class A and Class B ordinary shares, warrant liabilities, promissory notes to related parties (Constellation Sponsor LP), a convertible promissory note, and a deferred underwriting fee payable upon Business Combination closing. A Business Combination Agreement with HiTech was signed April 9, 2026.

Customers and end markets

Public shareholders who purchased Class A ordinary shares in the IPO, holding redemption rights. No commercial customers or end markets, as the company has no operating business.

Value-chain role

SPAC sponsor vehicle. Acts as an acquisition conduit, sourcing, evaluating, and negotiating a Business Combination target on behalf of public shareholders. All operating governance is focused on completing the HiTech transaction disclosed in the April 2026 filing.

Geographic exposure

Incorporated in the Cayman Islands. Warrant agreement designates New York State courts and the U.S. District Court for the Southern District of New York as exclusive forums for legal disputes.
