- India signed a 15-year deep sea mining agreement with the International Seabed Authority in late September, sparking speculation about regulatory progress for the sector

TMC the metals company Inc. stock reached $8.66 last week, setting a new 52-week high for the deep sea mining company. 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.
The rally comes with some interesting twists. The company’s current ratio stands at 2.37, showing solid short-term liquidity.
But not everything has been smooth sailing. TMC reported Q2 2025 results that fell well short of Wall Street expectations.
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. Yet investor enthusiasm has remained strong despite the poor quarterly results.
September Surge Driven by International Developments
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 Developments Add New Dimension
Investor sentiment got a boost from political developments as well. 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.
Options traders are clearly betting on continued upside. Call volumes soared six times above expectations, showing strong positive investor sentiment.
The stock did experience a 9.7% decline recently, likely due to market volatility and concerns over upcoming earnings. Some analysts view current price levels as overvalued given the company’s pre-revenue status.
TMC’s RSI sits in overbought territory according to recent data. The company maintains strong liquidity 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. The average trading volume stands at 9.7 million shares.
