Terrestrial Energy is trading 5.61% down now at $4.48 after broader risk-off sentiment pushed major U.S. indexes lower, including the S&P 500 and Nasdaq Composite.

  • The decline follows a 9.79% drop on September 11, 2026.
  • Terrestrial Energy submitted a graphite qualification report to the NRC on September 10, but available coverage does not explicitly link it to the stock decline.
  • The market-wide selloff and elevated Federal Reserve uncertainty appear to be the clearest context.
