TMC stock rocketed on major financing news last month

TMC published a press release on June 16 announcing that it had entered into a new investment deal with Korea Zinc. In exchange for $85.2 million in cash, TMC sold 19.6 million shares of new company stock to Korea Zinc. As part of the deal, Korea Zinc also received three-year warrants to purchase an addition 6.9 million worth of common stock at a price of $7 per share.

At the time of the deal's announcement, the $7-per-share price to execute the warrants represented a substantial valuation premium -- but subsequent trading in June actually saw the stock surge above that level. Following news of the investment partnership with Korea Zinc, TMC also announced some significant refinancing news through a disclosure with the Securities and Exchange Commission (SEC).

In the June 18 SEC filing, TMC said that it waived a restriction on previously issued stock warrants that would have prevented the holders from moving through with a cashless exercise. The deal effectively allowed holders of its stock warrants to pay with the equivalent value in common stock in order to exercise the warrants, rather than paying in cash. As a result, the company expected that the move would lead to fewer shares of new common stock being issued through the warrants -- which means less dilution for shareholders.

Why has TMC stock fallen in July?

TMC stock has seen a small sell-off in July's trading, with the company's share price down roughly 2% in the month as of this writing. While there hasn't been any negative news for the company, the stock is taking a bit of a breather after reaching its highest valuation level since 2021 last month.

TMC's business performance outlook remains highly speculative, but there are signs that some key foundations are falling into place for the company. In April, President Trump signed an executive order to accelerate seabed mining projects. The order established a framework for the issuing of permits to be expedited, and TMC applied for its first commercial recovery permit shortly after the news. With the Trump administration making domestic mineral sourcing, the company could have opportunities to score some big wins.
