Lightbridge Corporation is a pre-revenue nuclear technology company developing Lightbridge Fuel™, an advanced metallic fuel for water‑cooled reactors that aims to boost output by up to 30% in new reactors and about 17% in existing pressurized water reactors while improving safety and proliferation resistance.
The company targets lead test rods and assemblies in commercial reactors in the early‑ to mid‑2030s and initial reload batch orders in the late 2030s, supported by long‑dated R&D partnerships with Idaho National Laboratory and membership in the DOE HALEU Consortium. Lightbridge held about $201.9 million in cash and cash equivalents as of December 31, 2025, after raising roughly $182.0 million via at‑the‑market equity programs during 2025, but expects substantial additional capital needs to fund an estimated $19.5 million of INL project obligations and broader development, fabrication, and licensing efforts.
Lightbridge Corporation files a post-effective amendment registering $350,000,000 of securities under a shelf registration, with an accompanying $150,000,000 “at the market” common stock prospectus supplement included in that shelf.
The amendment states the change was filed because the company expects it will no longer be a "well-known seasoned issuer" when it files its Form 10-K for the fiscal year ended December 31, 2025. The Sales Agreement with Jefferies LLC dated June 5, 2025 covers the at-the-market program; the filing discloses $19,143,332 of common stock has been issued and sold under that agreement as of the date of this prospectus. Shares outstanding were 34,152,062 as of February 20, 2026.
