The full-day summit brings together industry executives, investors, and policymakers to examine the global nuclear energy renaissance and the investment opportunities it presents.

PowerStack Forum at Nest Climate Campus – “From Capital to Capacity” Tuesday, September 22, 2026 | Nest Climate Campus, Jacob K. Javits Convention Center, New York, N.Y. Mr. Grae will speak on the panel “From Gigawatts on Paper to Power in the Ground” from 11:05 to 11:30 a.m. ET. The session will examine the physical, industrial, and policy capacity required to deliver new power infrastructure at scale, including generation, grid access, equipment, construction, workforce, and permitting. The invitation-only working forum, organized by PowerStack, convenes approximately 50 senior leaders from technology, power, infrastructure, capital, and policy around a single question: how to finance and deliver the power infrastructure required for AI and industrial growth. It takes place on the opening morning of Nest Climate Campus, a three-day Climate Week NYC platform at the Javits Center. <a href="https://www.globenewswire.com/Tracker?data=1WHacyVXnONG15xuey6fmb9VniCdAqzijjfKyo-fHwWtADzrFYVzkilJS8y6JFxaiE2kEozvdwgcs2RuJgVe3-XVyodzede_c06OgpGBhkJKJYcf3zCbw9-WginupNABonb4qpf4AczHRUlm8FKO259qmr0SQvyBn8IFJ5wrXpoHqz5iStZBm632knSPAQsp2lw14Tue8UzSccgJ95GKyw==" rel="nofollow" target="_blank" title="">Atlantic Council Nuclear Energy Policy Summit 2026</a> Wednesday, September 23, 2026 | The St. Regis New York, New York, N.Y. Mr. Grae will speak on the panel “Financial De-Risking of New Nuclear Projects” on Wednesday, September 23, from 2:00 to 2:45 p.m. ET. Hosted by the Atlantic Council Global Energy Center’s Nuclear Energy Policy Initiative on the sidelines of the United Nations General Assembly, the third annual summit will take stock of a year of major change in U.S. and global nuclear energy policy. Sessions will address new public- and private-sector partnerships to fund and deliver nuclear projects; the efforts of first-mover U.S. states to deploy next-generation nuclear technologies; nuclear energy’s role in meeting rising global energy demand; and the connection between domestic nuclear deployment and a strong civil nuclear export program.

Seth Grae, Chairman and Chief Executive Officer of Lightbridge, commented, “Fuel is one of the biggest levers on how much power a reactor can produce," said Seth Grae, Chairman and Chief Executive Officer of Lightbridge. "In Zurich, I will discuss where the fuel cycle is constrained today and why power uprates of the existing fleet are among the fastest and most capital-efficient ways to add new nuclear generation to the grid, which is what Lightbridge Fuel is being designed to enable.” “Our selection for DOE's Launch Pad program at Idaho National Laboratory gives us an accelerated pathway to a DOE-authorized facility to manufacture the full-scale lead test assemblies that utilities will run in their plants, with construction starting as soon as next year. That is exactly the kind of public-private pathway the Atlantic Council summit and the PowerStack forum are built around, and it is how policy support for new nuclear capacity turns into fuel loaded in reactors.” About Lightbridge Corporation  Lightbridge Corporation (Nasdaq: LTBR) is focused on developing advanced nuclear fuel technology essential to delivering abundant, zero-emission, clean energy and providing energy security to the world. The Company is developing Lightbridge Fuel™, a proprietary next-generation nuclear fuel technology for existing light-water and pressurized heavy-water reactors, significantly enhancing reactor safety, economics, and proliferation resistance. The Company is also developing Lightbridge Fuel for new small modular reactors to deliver the same benefits, plus load-following with renewables, on a zero-carbon electric grid. Lightbridge has entered into two long-term framework agreements with Battelle Energy Alliance, LLC, the United States Department of Energy’s operating contractor for Idaho National Laboratory, the United States’ lead nuclear energy research and development laboratory. DOE’s Gateway for Accelerated Innovation in Nuclear program has twice awarded Lightbridge to support the development of Lightbridge Fuel over the past several years.
