The Metals Company stock grabbed attention Wednesday after CFO Craig Shesky delivered a stark warning to short sellers. With nearly 14% of shares sold short, Shesky said those betting against TMC should be “quite nervous.”
The stock popped 24% in after-hours trading after rising 7% during regular hours. Shesky made his comments during an appearance on the Rock Stock Channel podcast.
TMC the metals company Inc., TMC
TMC wants to extract valuable metals from the Pacific Ocean floor. The company targets polymetallic nodules containing copper, nickel, cobalt, and manganese. These materials are essential for electric vehicle batteries and renewable energy technology.
The stock has experienced extreme volatility this year. Shares climbed as much as 854% before retreating 49% from October peaks. November alone saw a 17% decline, the worst monthly drop since July 2024.
Trump Order Boosts Mining Prospects
President Trump signed an executive order in April to speed up deep-sea mining operations. The directive targets China’s dominance in critical mineral supply chains.
TMC is now working with several government agencies. The company has ongoing discussions with the Department of Energy and the Pentagon. Shesky said these talks are progressing well.
“While I can’t point to a timeline or promise a specific headline, what I can say is that anybody who would be short the stock now, I would question what exactly is the thesis,” Shesky stated.
He noted that approximately 25 million shares are currently short. Any positive regulatory news could trigger a sharp price spike.
Financial Position Improves
TMC ended Q3 with $115 million in cash. The company also has access to potentially $430 million through existing warrants.
Water Tower Research analyst Dmitry Silversteyn said TMC may not need additional capital for the first time since going public. This marks a major shift in the company’s financial stability.
The company reported a Q3 net loss of $184.5 million versus $20.5 million last year. Despite the loss, management expressed confidence in their cash runway.
Resource Value Dwarfs Market Cap
Technical assessments published in August valued TMC’s underwater resources at $23.6 billion. The company’s current market cap sits around $2 billion.
This gap represents the core investment thesis for TMC bulls. If the company secures mining approval, the stock could jump substantially.
Shesky hinted that production could begin earlier than the stated Q4 2027 timeline. He said regulatory clearance could accelerate the company’s plans.
TMC currently operates under an exploratory license. The company needs full commercial mining approval to start operations. The regulatory path remains somewhat unclear, but management sounds optimistic about progress.
“Given the fact that we are in a strong cash position and given the fact that we are on a very clear path towards regulatory certainty, I don’t quite understand what the bet against this would be,” Shesky concluded.
