[Lightbridge](https://www.bullished.co/tag/ltbr/), which is developing a metallic nuclear fuel and has no revenue, fell 8.86% to $4.63 in Monday trading as of 12:35 p.m. ET, erasing about $16 million in market value, after it [reported a third-quarter loss](https://www.globenewswire.com/news-release/2026/11/02/3392979/24486/en/lightbridge-provides-business-update-and-announces-third-quarter-fiscal-2026-financial-results.html?ref=bullished.co) that roughly doubled to [$8.3 million](https://www.sec.gov/Archives/edgar/data/0001084554/000147793226006566/ltbr%5F8k.htm?ref=bullished.co).

## Spending up, revenue still zero

The wider loss came with zero revenue. Research and administrative spending both rose sharply, with general costs reaching $5.0 million.

In its prior quarterly [filing](https://www.sec.gov/Archives/edgar/data/1084554/000147793226004756/ltbr%5F10q.htm?ref=bullished.co), for the quarter ended June 30, Lightbridge reported no revenue and a net loss of $5.8 million.

## Share sales pay the bills

Lightbridge sold about 4.3 million shares through its at-the-market program for net proceeds of $48.9 million over nine months. About $91.4 million remains available under the $150 million program.

The company ended the third quarter with $236.7 million in cash and 13 employees.

## A fuel still in the lab

Lightbridge sells its design as Lightbridge Fuel, a metallic fuel for existing large reactors, new large reactors and small modular reactors. By the company's own account, the design is still in research and development and needs extensive testing and regulatory review before commercial use. Irradiation testing of fuel samples began at Idaho National Laboratory in November 2025.

The stock was on pace for its third straight daily decline and its biggest one-day drop since October 14, when it fell 10.1%. As of Friday's close, shares were down about 60% year to date, against a gain of about 11% for the S&P 500, and had slid 19% over the prior month. The stock sat 81% below its highest close of the past year, set on October 31, 2025.

Lightbridge is scheduled to report earnings on Tuesday, November 10.
