Collaboration Framework Encompasses Nuclear Fuel Transportation, Conversion and Deconversion, Microreactor Licensing and Deployment, Advanced Manufacturing, and Power Solutions for Data Centers and Remote Communities

New York, New York and Oak Ridge, Tennessee - Newsfile Corp. - September 4, 2026 - NANO Nuclear Energy Inc. (NASDAQ: NNE) ("NANO Nuclear" or "the Company"), a leading advanced nuclear micro modular reactor and technology company focused on developing clean energy solutions, nuclear fuel cycle capabilities and nuclear transportation solutions, today announced that it has signed a non-binding Memorandum of Understanding ("MOU") with Enveniam, LLC ("Enveniam"), a leading project integrator and provider of engineering, technology and project-delivery solutions, to explore a collaboration addressing nuclear fuel cycle infrastructure, microreactor commercialization, advanced manufacturing and end-user energy solutions.

Any specific services, funding, projects or commercial commitments between the parties would be subject to separate definitive agreements. "This MOU brings together two organizations with complementary capabilities across the advanced nuclear value chain," said Jay Yu, Founder and Chairman of NANO Nuclear Energy. "NANO Nuclear is building a vertically integrated platform spanning microreactors, nuclear fuel and transportation, while Enveniam brings extensive experience integrating complex nuclear and energy programs. By exploring opportunities together, we aim to strengthen the practical pathway from technology development to regulatory licensing, manufacturing and deployment, while preserving the flexibility to evaluate each potential project on its individual merits." "Enveniam is focused on bringing disciplined project integration, technical depth and delivery certainty to critical energy missions," said Doug Freund, President and Chief Executive Officer of Boston Government Services and Executive Officer of Enveniam. "NANO Nuclear is advancing a broad portfolio that touches several important parts of the emerging advanced nuclear market. This framework gives our teams the opportunity to assess where Enveniam's engineering, project controls, licensing, safety and operational capabilities can help translate promising nuclear technologies and infrastructure concepts into executable projects." Exploring Broad Cooperation Across the Nuclear Value Chain Under the MOU, NANO Nuclear and Enveniam expect to evaluate potential cooperation across six principal workstreams:

• Nuclear fuel transportation: engineering, safety, operational and regulatory support for NANO Nuclear's HALEU transportation systems, including transport-basket optimization, regulatory filings and security protocols.

• Conversion and deconversion: engineering design, criticality-safety analysis, integrated safety assessments and licensing-strategy support for potential uranium conversion and deconversion facilities.

• Microreactor commercialization: technical support for siting, licensing, engineering, fabrication, project controls, risk management, safety-basis development, operations planning and deployment readiness for NANO Nuclear's lead KRONOS MMR™ Energy System project or NANO Nuclear's portable microreactor designs.

• Advanced manufacturing: requirements development, project management, engineering design, baseline planning, earned-value management and operational-readiness support for a potential U.S.-based manufacturing facility for nuclear fuel, fuel components and microreactor modules.

• Domestic fuel supply chain: strategic, program-management, technical and compliance support spanning sourcing, fabrication, qualification, transportation and delivery.

• Commercial energy markets: joint market development and stakeholder engagement concerning potential electricity and process-heat solutions for data centers, remote and off-grid communities, Alaska Native organizations, island states and territories, and other energy-intensive users.

"Commercializing advanced nuclear technology requires more than a strong reactor design," said James Walker, Chief Executive Officer of NANO Nuclear Energy. "It requires disciplined licensing, safety analysis, project controls, supply-chain coordination, manufacturing planning and operational readiness....
