Letter of intent signed to assess deployment of Xe-100 in Pennsylvania and throughout Talen's market area. Note the related but separate Amazon-Talen $650M data center campus deal at Susquehanna nuclear plant — Amazon's nuclear strategy spans both X-energy SMRs and existing reactor offtakes.
First-ever NRC Category II fuel fabrication license (issued Feb 13, 2026 — 40-year SNM-7007 license, expires 2066). First new fuel fabrication license issued by NRC in over 50 years. Vertical construction began Nov 17, 2025 by Clark Construction Group ($48.2M Phase 2A contract). Capacity at full scale: 5 metric tons uranium / 700,000 TRISO pebbles per year — enough for 11 Xe-100 reactors. ~500 full-time staff at operational scale. Fuel qualification testing underway at INL Advanced Test Reactor (13-month irradiation campaign).
Joint Development Agreement signed September 15, 2025. Largest announced AMR fleet target in the UK to date — up to 6 GW deployment, enough power for 14M homes. Preferred first project: 12-unit, 960 MWe at Hartlepool. Estimated to generate $54B+ in UK economic activity. JDA is non-binding. EDF involvement notable — Hartlepool is an existing EDF/Centrica nuclear site.
Anchor project under Amazon's broader 5+ GW US deployment commitment by 2039. Initial 4-unit, 320 MWe deployment with option to expand to 12 units totaling 960 MWe. Amazon agreement provisions: first-priority allocation of Xe-100 manufacturing queue 2031-2039, right of first refusal on deliveries, most-favored-pricing including TRISO-X fuel. Construction targeted late decade.
First commercial Xe-100 deployment globally. Construction Permit Application filed by Long Mott Energy (Dow subsidiary) March 31, 2025; accepted by NRC May 2025 with 18-month review schedule, permit target Q1 2027. Will replace aging fossil fuel infrastructure at Dow's Seadrift Operations site, providing electricity AND industrial steam. EPC engineering partner: Fluor Corporation. Graphite core structures: Toyo Tanso ($40M contract for IG-110 fine-grain isotropic graphite).
X-energy's flagship reactor: 80 MWe / 200 MWt HTGR. Helium-cooled, TRISO-X fueled. Standard plant configuration is 4 modules = 320 MWe with industrial steam capability. Expandable to 12 modules = 960 MWe. Six decades of HTGR research lineage. Provides electricity AND high-temperature steam for industrial heat applications — a key differentiator for petrochemical, chemical, and industrial customers.
Initial DOE Advanced Reactor Demonstration Program (ARDP) award, October 2020. Part of cumulative ARDP cost-share of up to $1.2B (50/50 split). As of December 31, 2025, ARDP reimbursements totaled approximately $438 million.
Amazon strategic investment via Climate Pledge Fund, October 2024. Pairs with Amazon's commitment to deploy 5+ GW of Xe-100 capacity in the US by 2039 starting with the Cascade Advanced Energy Facility in Washington state.
Oversubscribed Series D in November 2025. Brought cumulative venture capital raised to approximately $1.81 billion before IPO.
Cumulative DOE ARDP cost-share reimbursements as of December 31, 2025. Total program ceiling is $1.2B with 50/50 cost-share. Funds Xe-100 development, TX-1 fuel facility construction, and licensing.
Nasdaq IPO priced at $23/share (21% above $16-19 range) on 44,254,659 Class A shares. 15x oversubscribed. Stock surged 27-31% on debut — implied market cap roughly $12B at open. Anchor commitment from ARK Invest up to $105M. IPO closes April 27, 2026.
