Why is Eureka Acquisition stock surging today?
Eureka Acquisition Corp (EURK) stock rose 8.4% pre-market to $12.50, driven by its merger with Marine Thinking Inc. The deal deadline was extended to September 3, 2026, and EURK secured a Nasdaq compliance extension. The combined entity, valued at $130M, will be listed on Nasdaq. Broader market gains were modest, with the S&P 500 up 0.5%.
