EURK’s S-4 is Marine Thinking. First print was May, not August.

SPAC Pulse 64

S-4 May 1. Amendment No. 2 August 17. The DA is not a new 8-K in August. The book opened in May.

EURKS-4S-4/A

Eureka Acquisition Corp is combining with Marine Thinking Inc. The first S-4 is May 1, 2026. That is the deal tape. An August print that looks like a DA on a noisy 8-K is the wrong clock.

S-4/A June 15 (No. 1) and August 17 (No. 2). Two months of comments is normal. The name belongs on the profile. Path-to-close is the S-4 stack, not a late Item 1.01 misread.

Pulse Impact

  • Previous Pulse: 55

S-4/A dated August 17, 2026. First S-4 May 1. Not investment advice.
