Lightbridge (LTBR) Q3 2026 earnings summary

Executive summary

• DOE Nuclear Energy Launch Pad selection at INL provides an accelerated pathway toward authorization for a Pilot Factory producing lead test assemblies; further agreements, reviews, and approvals are required.

• Development spans the DOE-authorized pilot factory and conceptual design of a future commercial-scale Fuel Factory.

• ATR irradiation and post-irradiation examination are advancing fuel development and qualification work.

Financial highlights

• Q3 2026 operating expenses were $10.3M, versus $5.2M; net loss was $8.3M, or $0.23 per share, versus $4.1M, or $0.16 per share.

• 9M 2026 operating expenses were $25.6M, versus $14.5M; net loss was $20.4M, or $0.62 per share, versus $12.4M, or $0.55 per share.

• 9M R&D increased to $12.6M from $5.3M and G&A to $13.0M from $9.2M as development activity expanded.

• Interest income was $2.0M in Q3 and $5.2M in 9M, up 82% and 148% YoY, respectively.

• Cash and cash equivalents were $236.7M at September 30, 2026, versus $201.9M at December 31, 2025; there was no debt.

Outlook and guidance

• Preliminary Pilot Factory development and construction estimate is ~$140M phased over ~five years; estimates depend on design, procurement, approvals, and project requirements.

• Management expects liquidity to cover at least 12 months; substantial additional funding will be needed beyond that period for development and commercialization.

• R&D, personnel, and operating expenditures are expected to increase as irradiation testing, fuel fabrication development, and Pilot Factory engineering advance.

• First meaningful quantitative results from post-irradiation examination of initial fuel samples are expected in H1 2027.
