Lightbridge (Nasdaq: LTBR) entered an initial engineering contract with Stern Laboratories to assess the thermal‑hydraulic (TH) performance of Lightbridge Fuel for light water reactors. The multi‑phase program includes electrically heated fuel simulator design, single‑ and nine‑rod CHF tests (600–2,200 psia), and a multi‑year testing program to support U.S. licensing. Phase 1 is estimated to take approximately one year to complete.
Lightbridge (Nasdaq: LTBR) praised the U.S. Department of Energy’s new UPRISE initiative, announced March 12, 2026, which targets 2.5 GW of additional nuclear capacity by 2027 and 5 GW by 2029 to expand U.S. nuclear output.
The DOE program includes supply-chain assessments, plant upgrades, and reactor restarts, and cites more than $289 billion in available loan authority with up to 80% financing for eligible projects. Lightbridge highlighted its fuel design and ongoing irradiation testing that began in November 2025 as positioning the company to support longer-term uprate goals.

Lightbridge (Nasdaq: LTBR) announced management will participate in four investor conferences and events in January–February 2026. President and CEO Seth Grae will present at the 28th Annual Needham Growth Conference on Jan 14, 2026 at 4:30 PM ET with a live webcast and replay available. He will speak at the Global Cleantech Investor Gala in Davos on Jan 19, 2026 at 8:20 PM CET delivering “The Need for Nuclear.”
Mr. Grae will join a panel at the Nuclear Energy Institute Nuclear Financing Summit on Jan 28, 2026 at 2:30 PM ET, and will keynote and panel at the World Nuclear SMR & Advanced Reactor Congress in London on Feb 10–11, 2026, including a Feb 11 session on advanced fuels and SMR scaling.
Lightbridge (Nasdaq: LTBR) began irradiation testing of its enriched uranium-zirconium alloy fuel material samples on Nov 19, 2025 in the Advanced Test Reactor (ATR) at Idaho National Laboratory (INL) under a CRADA.
Key points: capsule irradiation has started following fabrication and loading of coupon samples; the campaign will collect material performance data on microstructural evolution, thermal conductivity and burnup effects; selected samples will undergo post-irradiation examination at INL to support design qualification and future licensing reports.
Lightbridge (Nasdaq: LTBR) reported Q3 and nine-month 2025 results and operational progress on Nov 5, 2025. Key financials: cash and cash equivalents $153.3M and working capital ~$153.1M at Sept 30, 2025, up from ~$40M at Dec 31, 2024; stockholders' equity $153.5M. Financing provided $121.4M in the nine months, driven by $116.7M net ATM proceeds.
Technical milestones: co-extrusion of an eight-foot demonstration rod with depleted uranium-zirconium alloy; fabrication of enriched uranium-zirconium alloy samples matching commercial composition; samples loaded into an experiment assembly ready for insertion into the Advanced Test Reactor; three peer-reviewed papers at TopFuel 2025 validating safety and manufacturing scalability. Q3 net loss was $4.1M and nine-month net loss was $12.4M, reflecting higher R&D and G&A spend.
Lightbridge (Nasdaq: LTBR) presented three technical papers at the American Nuclear Society TopFuel 2025 conference (Oct 5-9, 2025) in Nashville, Tennessee.
The papers cover: a quantitative comparison method of Lightbridge Fuel vs conventional UO2 using an OECD/NEA Three Mile Island benchmark; a post-critical heat flux (post-CHF) conceptual assessment emphasizing a time-at-temperature strategy for return-to-service scenarios; and ABAQUS-based fabrication modelling validated with Idaho National Laboratory experiments to predict dimensions, stresses, and strains in co-extrusion fuel rod fabrication.
These peer-reviewed conference contributions highlight Lightbridge’s focus on fuel design, fabrication, and performance assessment and direct readers to ANS proceedings for full papers at www.ans.org or the TopFuel 2025 meeting page.
Lightbridge (Nasdaq: LTBR) received a Notice of Allowance from the Eurasian Patent Office on Nov 3, 2025 for a multi-zone nuclear fuel rod design.
The allowed claims derive from PCT application WO2023034173A1 (filed Aug 2022) and cover methods and apparatus to fabricate fuel rods by additive manufacturing with distinct radial and axial zones of refractory metals, alloys, and fuel materials (zirconium alloys with uranium, plutonium, or thorium). The company highlighted Eurasia as a key market with over 40 operating reactors and said the technology targets improved reactor economics, safety, and fuel utilization for light-water reactors and SMRs.
