Price Chart
Executive Summary
Terrestrial Energy Inc. (IMSR) received SEC effectiveness for its registration statement (File No. 333-291796) as of June 11, 2026. This EFFECT notice confirms that the company's S-1/A IPO registration is now qualified, clearing the company to proceed with pricing and listing on Nasdaq.

Actionable Insight
With the registration declared effective, Terrestrial Energy can price its IPO at any time — typically within 1-2 days.
