NEW YORK, August 22, 2026, 7:19 a.m. EDT

  • TMC rose 20.65% Friday on 3.7 times its three-month average volume.
  • The $0.82 gain added an estimated $355.7 million in common-equity value.
  • NOAA publication advances the review, but certification and environmental work remain.

TMC the metals company Inc. jumped 20.65% Friday after U.S. regulators published its consolidated deep-seabed application. The $0.82 gain added an estimated $355.7 million to common-equity value.

Stock chart for NASDAQ:TMC

That preliminary increase equals roughly 2.5 times TMC’s reported $143 million liquidity. The calculation uses 433.7 million common shares outstanding at June 30, so it excludes later share-count changes. It shows how strongly investors priced procedural progress.

The National Oceanic and Atmospheric Administration published the TMC USA-A application in the Federal Register. USA-A covers about 65,000 square kilometres and contains an estimated 619 million wet tonnes of nodules. TMC sees another 200 million tonnes of exploration upside.

Publication supplies public notice. It is not a permit. NOAA must still complete certification, interagency consultation and environmental review. A draft environmental impact statement, public comment and a final decision would follow.

“The regulatory picture is becoming clearer,” Chief Executive Gerard Barron said in Thursday’s quarterly update. His wording matters. Clearer does not mean complete. TMC second-quarter update

TMC remains pre-revenue. It reported a $60.1 million second-quarter net loss and $20.1 million of operating cash use. Exploration and evaluation expense reached $56.1 million, including a $37.2 million Allseas settlement and negotiated cost.

Financial debtNone reportedLimits current interest burden
The simple ratio divides liquidity by one quarter’s operating cash use. Project spending can vary sharply.

The company targets fourth-quarter 2027 commissioning for the Hidden Gem collection system. Its stated nameplate capacity is 3 million wet tonnes yearly. Both timing and output remain subject to approvals and execution.

Funding is another gate. TMC says major onshore U.S. capital spending depends on majority government support. No such final package was announced with the quarter.

Friday, August 21 closing changes. The companies differ materially in assets, stage and funding.

The sector move helped. Still, TMC outpaced MP Materials and USA Rare Earth. Its 20.62 million shares traded were nearly four times normal volume.

Those targets imply large upside. They also embed successful permitting and future production. TMC has no operating revenue to anchor a conventional earnings multiple.

The week ahead should test whether Friday’s volume carries through. Investors will watch NOAA’s review timetable and USA-B environmental scoping. The USA-B comment window runs through September 16.

Broader federal support for seabed minerals may help sentiment. Yet a separate proposed lease auction near the Northern Mariana Islands also highlights a long regulatory path.

Risks: NOAA may delay, narrow or reject the applications. Environmental litigation could lengthen review. Collection performance, processing economics, dilution and government funding remain uncertain. Friday’s rally leaves the shares exposed to any missed milestone.

Analyst target map

AVERAGE$10.80
+125.5%
Implied upside to the five-analyst average target. Consensus: Strong Buy. Range: $10.00–$12.25.
Investor read: TMC gained an estimated 2.5 times its reported liquidity in one session. NOAA publication is useful evidence of process movement, but it creates no revenue and guarantees no permit. Key risks are certification, environmental review, litigation, financing, dilution and collection-system execution.
