What X-Energy, Inc. told the SEC could break it.

Manufacture of proprietary TRISO-X fuel depends on access to HALEU (high-assay low-enriched uranium); if customers can't access HALEU, fuel production is impaired — a known enrichment-supply chokepoint.

“If our customers are unable to access HALEU, our ability to manufacture TRISO-X fuel will be adversely affected, which could have a material adverse effect on our business, financial condition, operating results and future prospects.”

Flagship Xe-100/Dow project depends on DOE Advanced Reactor Demonstration Program 50% cost-share (.2B of .4B; ~M received as of FY2025), subject to budget-period limits and outside dates; cost overruns fall on X-Energy and Dow.

“Our ability to receive ARDP funding is subject to budget period limitations, extension approvals, and an outside date, and we may not receive the full amount of the ARDP reimbursement. Our current ARDP Agreement provides for 50% reimbursement of .4 billion in eligible costs (.2 billion in total reimbursement).”

Relies on a limited number of suppliers for highly specialized materials and components designed for first-of-a-kind or sole use in the Xe-100 reactor, some not yet qualified — exposing manufacturing to shortages and cost increases.

“We rely on a limited number of suppliers for certain materials and supplied components, some of which are highly specialized and are being designed for first-of-a-kind or sole use in the Xe-100.”
