FOR IMMEDIATE RELEASE

Lightbridge Provides Update on Nuclear Fuel Commercialization Plan,
Business Update and Financial Results for First Quarter 2016

RESTON, Va., May 5, 2016 -- Lightbridge Corporation (NASDAQ:LTBR) today issued an update on its commercialization strategy and provided a business update for the first quarter ended March 31, 2016.

Seth Grae, President & Chief Executive Officer of Lightbridge Corporation, commented, “During the first quarter, we achieved a number of key milestones that will help us to advance towards commercialization of our metallic nuclear fuel technology. In January, we announced that the Norwegian Institute for Energy Technology (IFE) received formal regulatory approval from the Norwegian Radiation Protection Authority for all planned irradiation of our metallic fuel at the Halden research reactor. This is the final regulatory approval in Norway required to begin testing of our advanced metallic fuel under commercial reactor operating conditions in the Halden research reactor in 2017.”

“We have made significant progress securing strategic partnerships for fuel fabrication and manufacturing. As previously disclosed, in March 2016, we entered into a joint development agreement with AREVA to assess establishing a joint venture in 2016 to develop, manufacture and commercialize fuel assemblies based on Lightbridge's next generation metallic nuclear fuel technology. We also entered into an initial services agreement with BWXT Nuclear Energy, Inc. to evaluate the ability to fabricate and prepare a preliminary plan for fabrication of Lightbridge-designed partial length nuclear fuel samples at BWXT facilities in the United States. At the same time, we have received strong support from the industry and from four of the leading U.S. nuclear operators, which continue to advise Lightbridge on our nuclear fuel program. We continue to see interest internationally for our metallic nuclear fuel technology, which is safer, increases power output and improves the operating economics of existing reactors.”

“We will further minimize costs and dilution through cost-sharing arrangements with fuel vendors, fuel manufacturers and other strategic partners. In the meantime, we continue to carefully manage our expenses to minimize our cash burn rate, while maintaining no long-term debt.”

Financial Results

For the first quarter ended March 31, 2016, Lightbridge’s net loss was $0.3 million, or a loss of $(0.02) per share, on revenue of $0.2 million. In the same quarter of 2015, the net income was $0.1 million, or earnings per share of $0.01 per share, on revenue of $0.1 million. All revenue was generated from consulting services. Stock-based compensation expense was $0.2 million for the quarter ended March 31, 2016 compared to $0.1 million for the quarter ended March 31, 2015. Excluding the impact of warrant revaluation for the derivative warrant liability, net loss for the quarters ended March 31, 2016 and 2015 would have been $1.6 million and $1.1 million, respectively. (See “About Non-GAAP Financial Measures” near the end of this release). For the first quarter ended March 31, 2016, the Company’s cash flows used in operating activities were $1.3 million versus $1.0 million used in operating activities for the same period of 2015.

Commercial Nuclear Energy Market Opportunity

The commercial nuclear energy industry is projected to grow rapidly at a time of rising global demand for reliable, carbon-free, base load electric power. There are currently 436 operable civil nuclear reactors in 30 countries around the world, with 67 reactors under construction and 488 on order, planned or proposed, according to the World Nuclear Association. By 2040, the International Energy Agency projects a 58% increase in nuclear capacity from a combination of power uprates and reactor construction. While some older reactors are closing in the U.S. and Europe, the global market is growing.

The Company believes the presentation of net income excluding warrant revaluation income is relevant and useful by enhancing the readers’ ability to understand the Company’s operating performance. The Company’s management utilizes net income excluding warrant revaluation income as a means to measure operating performance. The table below reconciles net income (loss) excluding revaluation income, a non-GAAP measure, to net income for the three months ended March 31, 2016 and 2015.
