Eureka Acquisition Corp 8-K

What Happened

• Eureka Acquisition Corp (the SPAC) filed an 8-K on June 23, 2026 reporting Amendment No. 1 to its Business Combination Agreement (BCA) with Marine Thinking Inc. and 17358750 Canada Inc. The original BCA was entered on October 29, 2025 and previously reported on November 3, 2025.
• The amendment, executed on June 12, 2026, revises Section 5.19 of the BCA to change the requirements for the SPAC’s post-closing directors. Except for this change, the BCA remains in full force and effect. The full Amendment No. 1 is attached as Exhibit 2.1 to the 8-K.

Key Details

• Parties: Eureka Acquisition Corp (SPAC), Marine Thinking Inc. (target), and 17358750 Canada Inc. (Amalgamation Sub).
• Original BCA date: October 29, 2025; Amendment date: June 12, 2026; 8-K filed: June 23, 2026.
• Amendment purpose: revise requirements related to the composition/eligibility of post-closing directors (Section 5.19).

Why It Matters

• For investors, changes to post-closing director requirements affect who will sit on the combined company’s board after the merger closes, which can influence governance, strategic direction and oversight.
• The amendment does not change other terms of the business combination agreement, so financial and closing mechanics previously disclosed remain in effect unless further amendments are filed.
