AOMC and Odyssey Merge in $1B Deal to Revolutionize Deep-Sea Mining for Energy Transition
April 8, 2026
Investor materials outline a multi-jurisdiction platform with strong U.S. alignment, partnerships, and a path to feasibility studies and potential market readiness.
Closing is expected in late Q2 to early Q3 2026, subject to regulatory and shareholder approvals, with advisory roles disclosed for Citi, Cantor Fitzgerald, and others.
Commodity price volatility for nickel, cobalt, and copper could affect project economics and funding timelines amid a long development cycle.
AOMC and Odyssey Marine Exploration are merging in a $1 billion all-stock deal to form a deep-sea mining platform focused on critical minerals for the energy transition, with Nasdaq listing expected after regulatory and shareholder approvals.
Former Rio Tinto CEO Tom Albanese will lead the combined entity, bringing experience in capital-intensive mining projects and navigating regulatory environments.
The merger unites American Ocean Minerals (AOM), a deep-sea mining firm formed earlier this year, with Odyssey Marine for a large portfolio of underwater mineral deposits.
Environmental groups and researchers warn that environmental risks may outweigh short-term benefits, calling for better understanding and non-extractive approaches to support the energy transition.
Disclosures include forward-looking statements, SEC filing plans (S-4), and risk factors tied to regulatory approvals and commodity prices.
Execution hinges on a multi-year regulatory process, starting with NOAA's review of the exploration license under the Deep Seabed Hard Mineral Resources Act, followed by environmental assessments and permits.
The combined company stresses responsible environmental and community engagement, with a phased data collection plan to build a science-based case.
Policy developments, including expedited permitting and new bilateral agreements, will influence the cycle and the company’s ability to capitalize on the trend.
Primary targets are polymetallic nodules containing nickel, cobalt, copper, and manganese, with potential rare earths and titanium in Cook Islands licenses.
