Investment Thesis

MONOPOLY: Only supplier of IG-110 nuclear-grade graphite used in ALL HTGRs globally (Japan HTTR, China HTR-PM, X-energy Xe-100). $40M X-energy supply agreement. No substitute exists. Micro-cap with massive leverage to SMR/HTGR buildout.

Risk

HTGR commercialization timeline uncertain. Small revenue base. Xe-100 construction delays would push out revenue.

Monitoring Trigger

X-energy Xe-100 construction milestones. HTGR orders from other countries.
