Constellation Acquisition Corp I 8-K

What Happened
Constellation Acquisition Corp I (CSTAF) announced on June 26, 2026 that it drew $5,000 under an existing unsecured promissory note from Constellation Sponsor LP and deposited those funds into the company’s trust account. The deposit, approved by the board’s extension committee, extends the deadline to complete the company’s initial business combination from June 29, 2026 to July 29, 2026.

Key Details

• The $5,000 draw (the “Extension Funds”) was made on June 26, 2026 and deposited into the trust for public shareholders.
• Funds were provided under an unsecured promissory note dated January 30, 2024 between the Company and Constellation Sponsor LP.
• This extension is the fifth of up to eleven one-month extensions permitted under the company’s amended and restated memorandum and articles of association.
• The Note bears no interest and matures upon closing of the initial business combination; if no combination occurs, repayment is limited to amounts remaining outside the trust account, if any.

Why It Matters
For SPAC investors, this filing confirms the sponsor provided additional money to keep the trust intact and buy one more month to complete a business combination. The amount is small ($5,000) and comes with no interest; it does not change the underlying trust value for public shareholders but preserves the possibility of completing a deal by July 29, 2026. If the company still fails to complete a business combination, investors should note repayment to the sponsor is only from any leftover funds outside the trust.
