Executive Summary

Eureka Acquisition Corp filed a 425 communication reporting an amendment to its business combination agreement with Marine Thinking Inc., revising only the post-closing board composition to specify eight directors (seven designated by Marine Thinking, one by the IPO sponsor) with at least five Canadian citizens. No financial terms were changed, and the deal remains on its original terms.

Key Financial Metrics

Deal Type
merger

Key Facts

  • Amendment No. 1 to the BCA dated June 12, 2026, revises Section 5.19 regarding post-closing directors.
  • Post-closing board will consist of eight directors: seven designated by Marine Thinking (four independent, one financial expert) and one by the IPO sponsor.
  • At least five of the eight directors must be Canadian citizens.
  • No financial terms, deal value, or closing conditions were changed.
  • The BCA otherwise remains in full force and effect.

Financial Impact

No financial impact — amendment addresses only board composition, not deal economics.

Risk Factors

  • Deal still faces time pressure — the SPAC extended to July 3, 2026, and has not yet scheduled a shareholder vote.
  • No material progress on closing — board composition changes are administrative, not substantive.
