Constellation Acquisition Corp I (NYSE:CSTA-WT) is a blank check company, or special purpose acquisition company (SPAC), incorporated in the Cayman Islands and focused on effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar initial business combination with one or more businesses, particularly those offering sustainable competitive advantages, substantial growth opportunities and at an inflection point in development, with emphasis on technology, media and telecommunications sectors across Asia, Europe and North America. The company, founded in 2020 and headquartered at 200 Park Avenue, 32nd Floor, New York, NY 10166, United States, maintains no current significant operations beyond pursuing such a combination and holds trust account funds for public shareholders pending completion. Its sponsor, Constellation Sponsor LP, provides operational support via unsecured promissory notes; as of November 2025, the sponsor funded a $5,000 deposit marking the tenth of eleven permitted monthly extensions, pushing the deadline for an initial business combination to December 29, 2025 from November 29, 2025. The company voluntarily delisted its Class A ordinary shares, redeemable warrants and units from the New York Stock Exchange in late 2023 to trade on the OTCQX Marketplace, reducing compliance costs to prioritize merger activities; earlier extensions through 2025, alongside shareholder approvals for up to eleven months of further deferral to January 2026, reflect ongoing efforts to secure a target amid substantial public share redemptions totaling approximately $27.43 million in early 2025. Leadership comprises experienced executives including CEO Chandra R. Patel and a team with over 50 years of combined investing expertise.
