Lightbridge reports US$236.7M cash as nuclear-fuel spending rises

At Sept. 30, cash and equivalents stood at US$236.7 million for Lightbridge Corporation NASDAQLTBR, the nuclear-fuel developer reported on Monday. Operating cash use reached US$13.2 million for the first nine months of 2026, compared with US$8.1 million a year earlier.

The company's Nov. 2 results show a third-quarter net loss of US$8.3 million, against US$4.1 million a year earlier. Research and development expenses rose to US$5.3 million from US$2 million as staffing, computing and laboratory costs increased.

Lightbridge is developing fuel for existing and new reactors. Its first irradiated material samples are undergoing examination at Idaho National Laboratory, while agreements and scope for a proposed pilot factory remain under negotiation. Construction and operation still require further federal agreements, reviews and authorizations.

Shares closed at US$5.08, down 5.93 per cent, on Nasdaq at 4 p.m. EDT on Oct. 30, according to the NASDAQLTBR quote page. That closing price predates Monday's results.

Cash increased from US$201.9 million at Dec. 31, 2025, helped by share sales. During the first nine months of 2026, Lightbridge sold approximately 4.3 million shares through its at-the-market program for net proceeds of US$48.9 million.

For the quarter ended Sept. 30, the program raised US$4.5 million. At Sept. 30, another US$91.4 million remained available for sale under the program, representing potential additional equity issuance rather than cash already received.

Third-quarter general and administrative expenses reached US$5 million, compared with US$3.2 million a year earlier. Total non-cash stock-based compensation was US$2.4 million for the quarter, so reported expenses and operating cash consumption measure different demands on the balance sheet.

Pilot Factory Still Requires Federal Authorization

Lightbridge's August selection for the Department of Energy's Launch Pad INL program provides a pathway toward authorization for a pilot factory to manufacture lead test assemblies. Selection itself does not authorize construction or operation.

In its Sept. 8 shareholder letter, management said preliminary estimates indicated existing financial resources could fund the pilot factory's construction, operation and decommissioning. Detailed cost estimates were still being developed.

That letter distinguished the pilot factory's DOE authorization pathway from Nuclear Regulatory Commission licensing for a separate commercial-scale fuel facility. Management said utilities wanted lead test assemblies in commercial reactors by the mid-2030s and large-scale commercial use by 2040, dates it aimed to meet or beat.

The testing counterparty is Battelle Energy Alliance, the laboratory's operating contractor. An August task statement covers experimental design, assembly and irradiation of clad uranium-zirconium fuel rodlets under conditions representative of commercial reactors, followed by shipment and disposition.

"We believe the loop irradiation will allow us to go from the ATR directly to lead test assemblies in commercial nuclear power plants, rather than first deploying segments of fuel rods and lead test rods in commercial reactors," chief executive Seth Grae said in Monday's release.

Elsewhere in the fuel supply chain, Centrus Energy Corp. NYSELEU said on Oct. 29 it was shipping its first new centrifuge for an Ohio enrichment expansion, with initial additional capacity expected in 2029.

Lightbridge's next scheduled update is its Nov. 2 conference call, at 4 p.m. EST, covering results and fuel development.
