The Metals Company stock touched $8.66 last week, marking a new 52-week high for the deep sea mining company. This price point caps off a year of explosive growth that has turned heads across the mining sector.

The stock has climbed 744% over the past 12 months. Year-to-date in 2025, shares are up more than 560%.
The company now carries a market capitalization of $3.46 billion. Its current ratio stands at 2.37, indicating solid short-term liquidity.
But the rally hasn’t been without bumps. TMC reported Q2 2025 results that missed Wall Street expectations by a wide margin.
The company posted a loss of $0.20 per share. Analysts had forecast a loss of just $0.05 per share.
The earnings miss represents a four-fold increase over expected losses. Despite the poor quarterly results, investor enthusiasm has remained strong.
Regulatory Developments Fuel Speculation
September proved to be a turning point for TMC stock. The shares jumped 18.8% during the month after declining in both July and August.
The catalyst wasn’t a company announcement. Instead, investors reacted to external developments in the deep sea mining space.
India signed a 15-year agreement with the International Seabed Authority in late September. The deal grants India exclusive exploration rights for polymetallic sulphides in the Indian Ocean.
These materials are similar to the polymetallic nodules TMC plans to mine in the Pacific Ocean’s Clipperton Clarion Zone. The agreement sparked speculation that the ISA might be moving closer to finalizing regulations for deep sea mining operations.
TMC has been waiting for these final rules before beginning commercial mining activities. Any progress on the regulatory front could unlock the company’s operational timeline.
Political Interest Adds Another Layer
Investor sentiment also got a boost from political developments. Reports emerged that the Trump administration is in talks with Lithium Americas about a possible equity investment.
The news matters because both Lithium Americas and TMC are Canadian companies. Some investors had assumed Canada-based firms wouldn’t attract U.S. government interest.
MP Materials previously partnered with the Trump administration earlier this year. That deal sent MP Materials stock climbing sharply.
Now investors are wondering if TMC could be next in line for similar government backing. The speculation has added fuel to an already hot stock.
TMC’s stock shows an RSI in overbought territory according to recent data. Some analysts view current price levels as overvalued given the company’s pre-revenue status.
The company maintains a strong liquidity position but faces questions about the profitability of seabed mining. TMC has not yet begun commercial operations and continues to burn cash while awaiting regulatory approval.
