Regulatory shift puts TMC the metals (TMC) back in focus

Fresh U.S. government initiatives around deep-sea resource development have put new attention on TMC the metals (TMC), which has been waiting on International Seabed Authority mining rules to clarify its commercial pathway.

At a share price of $6.64, TMC has recently seen a 3.59% 1 day share price gain, while its 90 day share price return of 17.73% and very large 1 year total shareholder return suggest momentum has been building despite some shorter term pullbacks.

With TMC still pre revenue, a loss of $295.507 million and a value score of 1, plus a US$6.64 share price at a large discount to the US$11.00 analyst target, is this genuine mispricing, or is the market already banking on future growth?

Preferred multiple of price to book: Is it justified?

With TMC reporting negative shareholders equity and a P/B ratio of -67.6x against a US Metals and Mining industry average of 2.7x, the normal playbook for comparing valuations breaks down quickly.

P/B is usually a simple yardstick: you compare a company’s market value to the net assets on its balance sheet. For an early stage minerals explorer with negative equity and no meaningful revenue, that same metric becomes more of a red flag than a guide because it is heavily shaped by funding structure and accumulated losses rather than a productive asset base.

Here, the gap between TMC’s very large negative P/B and the industry average suggests the market is pricing the stock on future potential and option value, not on current book value. Without a usable fair ratio or DCF output in the data, you are essentially looking at a story driven more by expectations and balance sheet repair over time than by traditional asset backing.

Result: Price-to-book of -67.6x (ABOUT RIGHT)

However, you are still looking at a pre revenue miner with a US$295.507 million loss and heavy reliance on future seabed rules and project financing falling into place.
