On March 18, 2026, Constellation Acquisition Corp I announced an amendment to its existing unsecured promissory note with Constellation Sponsor LP, increasing the principal amount from $2.25 million to $5.25 million. This amendment follows a previous increase in June 2025, where the note was raised from $1.66 million to $2.25 million. The promissory note, which bears no interest, is set to mature upon the closing of the company's initial business combination. The company has indicated that all other provisions of the note remain unchanged. This increase in financing may provide the necessary capital for Constellation Acquisition Corp I to pursue its strategic objectives and complete its business combination, which is crucial for its operational execution and future growth prospects.
