TMC Deep Sea Mining Hopes Rest On ISA Ruling And Volatile Shares

Simply Wall St·02/14/2026 20:23:49
Listen to the news
  • TMC the metals (NasdaqGS:TMC) is seeking regulatory approval from the U.N. backed International Seabed Authority to begin commercial deep sea mining for battery grade metals.
  • The International Seabed Authority has not yet finalized its mining code, so TMC’s production plans remain contingent on that process.
  • The company has outlined a goal to start production by late 2027, with its initial project framed as a key value driver for the business and the broader deep sea mining industry.

TMC the metals, trading at around $6.09, sits at the center of a developing story in deep sea resource extraction. The stock’s return over the past year is 223.9%, and its very large 3 year return highlights how sensitive the share price has been to shifts in expectations around its project pipeline. More recently, the shares show a 5% decline over the past week and a 22.1% decline over the past month, which underscores how new information on regulatory timing can quickly feed into sentiment.

For you as an investor, the key variable to watch is the path and pace of decision making at the International Seabed Authority, since TMC’s ability to move toward its late 2027 production goal depends on that mining code. Any updates on environmental conditions, operating requirements, or project specific approvals could influence how the market views both the risk and potential scale of TMC’s first commercial development.
