TMC the metals company Inc., TMC
The stock has been one of the year’s biggest gainers. TMC has climbed 495.60% over the past year and 351.67% year-to-date.
Shares have ranged from $0.72 to $11.35 over the past 52 weeks. The company currently trades with a $2.24 billion market capitalization.
Liquidity Announcement Addresses Funding Questions
TMC revealed last week it maintains $165 million in total liquidity. This includes $121 million in cash following warrant exercises and available credit lines.
CEO Gerard Barron made a pointed statement about the balance sheet. He said TMC has “no need to come to the public markets anytime soon.”
That declaration matters to investors worried about dilution. Companies often need to sell new shares to fund operations, which can pressure existing shareholders.
The November update to the U.S. Critical Minerals List changed TMC’s profile. The U.S. Department of the Interior and U.S. Geological Survey added copper to the list.
All four metals in TMC’s polymetallic nodules now carry critical mineral status. These materials are considered essential for U.S. economic and national security.
Copper accounts for 17% of anticipated life-of-mine revenue based on TMC’s Pre-Feasibility Study. The critical designation applies to the entire suite of metals the company aims to extract.
Billion-Dollar Valuations and Regulatory Milestones
TMC published two economic studies in August showing a $23.6 billion project valuation. The reports broke new ground in the deep-sea mining sector.
The company announced 51 million tonnes of probable mineral reserves. This marked the first declaration of its kind anywhere in the world.
The Pre-Feasibility Study for the NORI-D area indicated a Net Present Value of $5.5 billion. These figures have provided fundamental support for the stock’s impressive run.
TMC’s subsidiary received full compliance notice from NOAA in August. The Metals Company USA gained confirmation of priority rights for both exploration areas.
NOAA forwarded its draft deep-sea mining rule to the White House. The proposed regulation would streamline the license and permit review process.
