- Expected to support initial Xe-100 deployments, TRISO-X fuel production and domestic fuel supply for part of X-Energy’s 11.5 GW pipeline.
- Follows a 9.29% regular-session gain to $20.82 and strong seven-day advance; broader markets were modestly lower, while company-specific news appears to be primary and likely explains after-hours strength.
