Seabed Mining Progress: Successful deep-sea mining tests and positive environmental impact assessments boost investor confidence, increasing stock price. Conversely, setbacks, regulatory hurdles, or environmental concerns negatively impact the price.

Metal Prices: Fluctuations in the market prices of nickel, copper, cobalt, and manganese, the metals targeted by TMC, directly affect the perceived value of its seabed nodules and thus, its stock price.

Regulatory Environment: International Seabed Authority (ISA) regulations regarding deep-sea mining significantly influence investor sentiment. Favorable regulations and approvals increase the stock price, while stricter rules or moratoriums decrease it.

Funding and Partnerships: Securing significant funding or establishing strategic partnerships with established mining companies or investors positively impacts the stock price, demonstrating financial stability and operational capability.

Overall Market Conditions: General market trends and investor sentiment towards speculative growth stocks influence TMC's stock price, regardless of company-specific news. Economic downturns may lead to selling pressure.

Environmental Concerns: Growing public and investor concern about the environmental impact of deep-sea mining can negatively affect TMC's stock price, even if the company adheres to regulations.
