NANO Nuclear Acquires Secured Transportation Services LLC for Integrated Nuclear Fuel Logistics Platform

NANO Nuclear Acquires Secured Transportation Services LLC, Establishing a Fully Integrated Nuclear Fuel Logistics and Transportation Platform and Joining a Select Group of Revenue-Generating Microreactor Developers

Acquisition adds more than 20 years of specialized nuclear transportation experience, accelerating NANO Nuclear’s fuel supply chain and reactor deployment capabilities.

NEW YORK, N.Y., May 26, 2026 (GLOBE NEWSWIRE) -- 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, today announced the acquisition of Secured Transportation Services LLC (STS), a specialized U.S. based, globally operating nuclear logistics, transportation and services company specializing in the safe, secure and compliant movement of radioactive and nuclear materials.

This acquisition represents a significant strategic milestone in NANO Nuclear’s evolution into a vertically integrated nuclear energy company by adding one of the most important and challenging elements of the nuclear fuel cycle: the capability to plan, coordinate, license, secure and execute nuclear materials transportation and related deployment activities.

With the addition of STS, NANO Nuclear is taking a decisive step toward becoming a leader in the next generation of nuclear energy infrastructure, with capabilities designed to support reactor deployment and the broader ecosystem required to enable commercialization at scale.

One of the most significant barriers to scaling advanced nuclear technologies is not the reactor itself, but the infrastructure required to support it, particularly fuel transportation. The transport of nuclear materials, particularly spent fuel, HALEU fuel and advanced reactor components, is one of the most highly regulated and operationally complex segments of the nuclear fuel cycle, with emerging capacity constraints expected as next-generation reactor deployments accelerate.

With STS part of the organization, NANO Nuclear is competitively well positioned to:

• Control and coordinate critical nuclear fuel transportation logistics.
• Support deployment planning for microreactors and related advanced nuclear systems.
• Reduce reliance on third-party nuclear logistics providers for core transportation and deployment functions.
• Navigate complex regulatory, security and route-approval requirements.
• Develop repeatable deployment models for defense, data center, industrial, remote and international customers.
• Support a broader ecosystem of nuclear fuel-cycle services expected to be required by NANO Nuclear and other nuclear industry participants.

Founded in 2005, STS brings more than two decades of specialized nuclear transportation experience and a strong track record of executing complex nuclear materials projects safely, securely and efficiently. STS personnel have completed projects in more than 40 countries, providing NANO Nuclear with operational experience in navigating various regulatory requirements, physical challenges and political environments. STS currently holds approvals for more than 90% of the active U.S. NRC approved spent fuel routes in the United States.

STS brings a team of highly experienced professionals with backgrounds spanning nuclear engineering, logistics, regulatory affairs, and operations - capabilities that are difficult to procure and essential to transporting fuel and deploying reactors at scale.

In addition, the acquisition of STS provides NANO Nuclear with revenue generating operations. For the twelve months ended December 31, 2025, STS generated audited revenues of approximately $7.1 million and net income of approximately $1.3 million, reflecting strong underlying profitability and operational efficiency. Equally as important, NANO Nuclear sees substantial opportunity for growth at STS in the coming years as demand for nuclear fuel transportation and logistics accelerates. STS is expected to benefit from NANO Nuclear’s relationships and exposure to several aspects of the nuclear fuel cycle, as well as NANO Nuclear’s strong financial position through prudent deployment of strategic growth capital.

The acquisition of STS directly supports NANO Nuclear’s broader strategy of building a fully vertically integrated business, spanning:

• Reactor design and development.
• Fuel sourcing and processing (LEU/HALEU ecosystem).
• Fuel transportation and logistics.
• Reactor deployment and installation.
• Long-term operational support.
  

By integrating STS into its operations, NANO Nuclear gains the ability to coordinate the movement of nuclear fuel and reactor systems from origin to deployment site, a capability that is expected to become increasingly valuable as demand for microreactors accelerates globally.

“This acquisition is about more than logistics, it’s about unlocking the full potential of advanced nuclear,” said Jay Yu, Chairman and President of NANO Nuclear. “With STS, we now control a vital link in the nuclear value chain that very few companies possess globally. This capability will allow us to move faster, deploy quicker, and deliver our technologies anywhere in the world. We are building infrastructure for the next generation of nuclear energy, and this is a major step forward.”

“This is a transformational acquisition for NANO Nuclear,” said James Walker, Chief Executive Officer of NANO Nuclear. “STS brings the kind of deep, specialized expertise that is essential to making advanced nuclear a reality at scale. Transportation is one of the most overlooked, but most critical, pieces of the nuclear value chain. By bringing STS into the NANO Nuclear ecosystem, we are removing a major bottleneck and positioning ourselves as one of the few companies capable of delivering a truly end-to-end nuclear solution. This acquisition doesn’t just strengthen our logistics capabilities, it accelerates everything: our fuel strategy, our deployment timelines, and our ability to serve customers across North America and internationally.”

As the global energy system shifts toward clean, reliable, and decentralized power, microreactors are expected to play a pivotal role. However, their success depends on the ability to safely and efficiently move fuel and systems where they are needed.

"For more than two decades, STS has built its reputation by executing complex nuclear transportation projects safely, securely and reliably,” said Roy Boyd, Founder & President of STS, who will continue in this role post-acquisition. “Joining NANO Nuclear gives STS the resources and platform to expand our capabilities while maintaining the safety-first culture, regulatory discipline and customer focus that have defined our company since its founding. We are benefitting from the industry’s growth and believe we are well-prepared to meet expected demand. We believe our logistics, training, consulting, security coordination, engineering and project execution experience will be highly complementary to NANO Nuclear's broader advanced nuclear strategy and advance the overall mission to meet growing demand for nuclear energy."

STS was acquired by NANO Nuclear’s existing transportation subsidiary, Advanced Fuel Transportation Inc., for total consideration valued at up to $13 million. The total purchase price is comprised of $6 million paid in cash at closing, subject to closing adjustments, and $7 million in restricted shares of NANO Nuclear’s common stock paid in several installments, a portion of which is subject to certain contractual contingencies. Additional information will be provided in a Form 8-K to be filed by NANO Nuclear with the U.S. Securities and Exchange Commission.
