IMSR: SEC Form POS AM filed by Terrestrial Energy Inc.
Post-effective amendment lets holders resell shares and warrants; stock at $2.94 vs $11.50 warrant exercise price, dilution risk.
What this filing says
Terrestrial Energy filed a post-effective amendment to a shelf registration that lets existing holders resell shares and warrants and lets the company issue shares. The stock's October 26, 2026 closing price of $2.94 is below the $11.50 per share warrant exercise price, so warrant holders may choose to exercise on a cashless basis. Selling holders may therefore add supply to the market, which matters to current shareholders.
