Executive Summary

Eureka Acquisition Corp (EURK) filed a 425 communication reporting that Nasdaq granted an extension through January 31, 2027, to regain compliance with the Public Float Rule (Rule 5450(a)(4)). The company had previously received a deficiency notice on August 27, 2026, and submitted a compliance plan on October 12, 2026. This removes a near-term delisting risk while the SPAC continues pursuing its pending merger with Marine Thinking Inc.

  • EURK submitted a compliance plan on October 12, 2026.
  • On October 26, 2026, Nasdaq granted an extension through January 31, 2027, to regain compliance.
  • The extension removes an immediate delisting overhang as EURK pursues its pending merger with Marine Thinking Inc.

Financial Impact
