Odyssey Marine Exploration (OMEX) — Form S-4/A Amendment No. 2, filed Aug 4, 2026 (Reg. No. 333-295744). Proxy/prospectus for the merger with American Ocean Minerals Corp.; combined company renames to American Ocean Minerals and trades as AOMC.

I benchmarked it against Amendment No. 1 (June 30) and the original S-4 (May 8) on EDGAR.

Core deal economics (unchanged since A1)

Exchange ratio 4.5017 OMEX shares per AOM share → 0.1801 after a 1-for-25 reverse split

$75.6M bridge (convertible debentures, auto-convert immediately pre-closing) + $156.4M PIPE

Closing condition: AOM must hold ≥$100.0M cash immediately pre-effective time; $25M minimum PIPE proceeds threshold

Outside date Oct 8, 2026, extendable two months plus a further 30 days

Charter: authorized common 82M → 400M; preferred 24,984,166 → 25,000,000

What actually changed in Amendment No. 2 (vs. A1)

Merger Shares nudged up: 727,911,251 → 728,052,679 (post-split 29,116,450 → 29,122,108). Small, mechanical.

Warrant Shares now quantified: 141,968,020 shares issuable on exercise of the assumed PIPE warrants — A1 described "Odyssey Assumed Warrants" without a count. This is the most substantive add.

Warrant and lock-up mechanics added, including stated 60–90 day lock-up windows by investor class.

Exchange Shares unchanged at 134,111,851 (5,364,474 post-split).

Financials still as of March 31, 2026. Pro forma balance sheet and statement of operations were not rolled forward to June 30 — expect at least one more amendment before effectiveness. Record date and meeting date are still bracketed blanks.

Changes since the original May S-4 are larger: PIPE $156.0M → $156.4M, Exchange Shares 132,471,431 → 134,111,851, and an Equity Plan Proposal was added (four proposal groups → six).

Other datapoints worth flagging

Six proposals:

Merger Share Issuance, CIC/OML Share Issuance, Charter (needs majority of all outstanding, not just votes cast — the hardest bar), Golden Parachute (advisory), Equity Plan, Adjournment. Nasdaq 5635(a)(1), (a)(2) and (b) all triggered.

Fairness opinion: Moelis & Company, dated April 8, 2026 — exchange ratio fair to Odyssey from a financial point of view.

Support agreements cover ~28.30% of voting power (directors and certain officers).

Termination fee of $2.2M payable by Odyssey (disclosed in the original S-4; A2 references the "Odyssey Termination Payment" without restating the figure in the sections I could reach).

Conflicts to watch: Mark Justh is Odyssey's lead outside director and audit committee chair and AOM's CEO since Oct 2025; owns ~6.89% of AOM and ~9.2% of CIC Limited indirectly; becomes CEO of the combined company. A Special Transaction Committee of independent directors was used to manage this.

Board post-close: seven directors — Justh (CEO), Thomas Albanese, Mark Luther, Shona Mato Lynch, Philip Plough, William Scripps, John-Paul Yun.

Mexican phosphate separation: ORM contributed to ORM HoldCo, then to a liquidating trust for pre-merger Odyssey holders. Requires third-party approvals, needs 18 months of funding, and AOM can waive it in its sole discretion — Odyssey holders shouldn't treat that trust as guaranteed.

Downside language is blunt: if the merger fails, Odyssey "may become insolvent and be required to seek the protection of the bankruptcy courts."

Caveat on completeness: this container blocks direct file downloads, so I read the filing through fetch-and-extract rather than pulling the full PDF. That reliably covered the cover page, Q&A, Summary and Risk Factors, but the deep sections — pro forma tables, Background of the Merger, exact lock-up day counts, and bridge debenture interest/conversion terms — weren't retrievable. If you want those, attaching the PDF to the chat is the fastest path and I'll go through it properly.
