Description
Holtec is a U.S.-headquartered, multinational technology company specializing in the energy sector, with its principal focus on nuclear power generation and an expanding presence in adjacent clean energy generation solutions and long-duration energy storage. Our founder, Dr. Krishna P. Singh, a widely recognized inventor and entrepreneur, has led the Company since its inception in 1986. We believe that our established position in multiple sectors of the nuclear power industry has been facilitated by our sustained development of innovative technologies, covered by 217 granted patents worldwide as of March 31, 2026, that help protect our IP from unauthorized appropriation by others, as well as other confidentially held IP. Our innovative solutions extend across a full spectrum of disciplines applicable to nuclear power plants, including design, engineering validations, licensing, manufacturing, site construction, commissioning, operations and decommissioning. We provide SSCs and specialty services to the nuclear power industry for our global clients, many of whom are Fortune 500 companies and among the largest in their respective countries. As a vertically integrated, turnkey nuclear technology company, we deliver our goods and services to our customers while maintaining control of all key elements of product delivery, which we believe makes us uniquely positioned to address the growing needs of the global nuclear market. We operate on five continents through 13 operation centers and have a client base that includes more than 150 commercial nuclear reactors, as of March 31, 2026. We are a leader in the nuclear energy sector in four primary business activities that cut across our legacy operations, our SMR development program and our relatively new renewable energy program: (i) provision of goods and services for the management, storage and transportation of spent nuclear fuel; (ii) restart of decommissioned nuclear power plants and provision of decommissioning services to shutdown nuclear power plants; (iii) development and turnkey supply of SMRs, which are engineered to provide 24/7, clean energy; and (iv) development and deployment of our solar and energy storage technologies that will complement our SMR-300 clean energy solution. We believe that we are the only company in North America that provides a broad range of SSCs and specialty services to the nuclear power industry, is licensed to operate a nuclear reactor and has the distinction of pioneering the restart of a shuttered nuclear plant, a milestone previously viewed by many as unattainable in the United States. Our main business lines to date, comprising decommissioning services, spent fuel storage and transportation solutions and related services, include businesses characterized by long-duration, contracted cash flows with highly rated, stable counterparties. Since our inception, we have been conservatively managed with limited indebtedness. We have grown from a small, niche nuclear supplier in the 1980s to a leading nuclear company, with more than 90% U.S. market share in wet spent fuel storage and approximately 75% U.S. market share in dry spent fuel storage for operating plants as of March 31, 2026, which speaks to our proven ability to expand into and lead new markets. Our goal is to replicate this success in the developing SMR sector by utilizing our established turnkey project delivery model to deliver the SMR-300 to our customers with engineered passive safety features that are designed to make the SMR-300 Walk-away-safe and with other design attributes to make the SMR-300 universally deployable and land-efficient. We are a leading SMR developer that owns the Palisades nuclear plant and has access to four other nuclear sites (Oyster Creek, Pilgrim, Indian Point and Big Rock Point) in the United States, which we expect will serve as prequalified locations to deploy our SMR-300 plant, subject to receipt of required regulatory licenses and other approvals for our SMR technology. We were also the only SMR developer selected by the DOE in December 2025 for its coveted Tier 1 First Mover Award, which we expect will provide us a $400 million grant to accelerate deployment of our first dual-unit SMR-300 plant (named Pioneer One and Pioneer Two) at our existing Palisades site in Michigan, subject to certain conditions, including the negotiation and execution of a funding agreement. Based on our knowledge of the emerging SMR industry, we believe that Pioneer One and Pioneer Two will be among the first SMRs commercially operating in the United States. We operate three advanced manufacturing plants, one each in New Jersey, Pennsylvania and Ohio, that feature over one million square feet of aggregate production capacity. These plants enable us to serve our diverse, global client base through timely deliveries and rigorously quality-controlled SSCs and specialty services. We also maintain a commercial relationship with Holtec Asia, an affiliate owned and controlled by our founder. Holtec Asia operates a manufacturing facility in Gujarat, India that supplies air-cooled condensers and is a leader in renewable energy technologies. Our relationship with Holtec Asia provides us with access to its technical capabilities and supports our efforts to pursue opportunities in the large SMR market in India and other parts of Asia and Africa. We believe that the combination of our substantial IP portfolio and our advanced domestic manufacturing facilities positions us to capture a wide range of opportunities across the entire nuclear lifecycle, from new build reactor operations to recommissioning of shuttered plants and life extension of existing nuclear plants. Our capabilities and certifications position us to play a critical role in the supply chain for both traditional light-water reactors, including Western- and Russian-designed systems and evolving next-generation reactor technologies. With a strong commitment to public health and safety, research and development and social and environmental responsibility underpinned by a global footprint spanning North America, Europe, Asia, Africa and South America, we are well-positioned to contribute to the Trump administration’s ambition to expand commercial nuclear energy generation. We believe that our integrated capabilities, innovative technologies and project execution track record make us a trusted partner to deliver on our commitments to our global clients, which include utilities, governments, off-takers and industrial companies. Our ability to maintain customer relationships will depend, in part, on our continued performance, regulatory compliance and cost competitiveness. Our business model varies by the industry sector, but in all instances, it is supported by our vertically integrated delivery model, extensive regulatory experience and innovation-driven approach. Our leading position in spent fuel storage was attained by our turnkey, single-responsibility delivery model, which enabled us to capture additional financial margin while simultaneously mitigating our customers’ risks. While this model may allow us to capture additional margin, it may also increase our responsibility for design, procurement and construction risks. Our advanced cloud-based project management and quality assurance systems, refined through nearly four decades of sustained use, further enhance operational efficiency and risk management strategies, supporting a track record of hundreds of completed projects delivered on-time. In decommissioning, we led the industry in pioneering the “acquire the plant and decommission” model, making us the largest owner of shuttered nuclear reactor units in the United States as of March 31, 2026. Pursuant to NAMCO Restructuring Phase I, which will have been completed prior to the closing of this offering, certain decommissioning assets and associated liabilities have been transferred from NAMCO to DEAMCO, a subsidiary of our affiliate, Holtec Holdings. Following the completion of NAMCO Restructuring Phase II, which remains subject to NRC and certain other regulatory approvals and may not be completed prior to the closing of this offering, we expect to continue to generate decommissioning services revenues pursuant to a contractual services arrangement with DEAMCO, the new owner of these assets. We also expect to collaborate with DEAMCO to pursue future development opportunities at these sites, including the potential deployment of our SMR-300 reactors. We intend to lead the licensing, procurement, construction and commissioning of SMR-300 plants to address the growing global shortage of baseload, carbon-free power. In addition to the full-scope procurement and construction of SMR-300 plants, we have established a fully integrated project development subsidiary, Energetics, to lead commercial development of SMR-300 projects, starting at the nuclear plant sites we currently own. Our project development capability builds on the Palisades restart project where we have successfully managed the off-take arrangements, permits and project financing, and have established ourselves as an INPO-accredited and NRC certified nuclear operator. The recommissioning of the shuttered Palisades nuclear plant, which would be the first restart of a shuttered nuclear power plant in the United States, is in the final stages with all major upgrades completed and a limited number of minor modifications required for restart. These minor modifications must be completed with the same care and rigor as the major modifications to ensure long-term reliable plant performance. The completion of the remaining modifications and final commissioning of the Palisades restart project is expected in 2026, in advance of our commitment date with our counterparties of March 2027. We believe our depth and breadth of experience—spanning more than 40 years of successfully executing complex nuclear projects—positions us to effectively address the project execution challenges and quality issues that have negatively affected nuclear plant construction for decades. Consistent with our full-spectrum capabilities, through Energetics we offer both a Build-Own-and-Operate model and a Develop-to-Deploy model to the industry. We believe this flexibility differentiates us from our domestic competitors and allows us to better compete with government-owned foreign suppliers. In collaboration with Hyundai E&C, we expect to utilize our vertically integrated capability to deliver reactors to our own sites as well as to our global customers. We believe that our nuclear plant operational capabilities and certifications will be valuable to countries that are in the early stages of developing nuclear power programs. Our plant operational capabilities, however, are not expected to be utilized extensively in the United States or in other countries that currently operate established nuclear facilities. While we have an established operating history of executing highly complex nuclear projects, nuclear projects are capital-intensive undertakings that require extensive regulatory approvals and ongoing compliance with applicable laws and regulations as well as multi-stakeholder project delivery and management, and they may be subject to significant delays, cost overruns or other uncertainties beyond our control. Our full product portfolio is broad, premised on a combination of our existing mature product lines and new or maturing technologies that are future-focused or nascent in their state of development. Our mature product offerings include high-density racks for wet storage of spent fuel, high-capacity dry storage and transport systems for used nuclear fuel and high-level waste, air-cooled condensers and advanced heat exchangers. Our SMR-300 reactor is, as of the date of this prospectus, in a pre-construction stage reflective of completed technical design, site selection, partial financing via the DOE LGA Facility and site preparation work, and we believe the SMR-300 could be among the first SMRs to be commissioned in the United States. Our Holtec Green Boiler (HGB), which is an innovative, high-capacity, long-duration thermal energy storage system, and our HI-THERM HCSP, our hybrid solar energy capture system, are both recently developed technologies that could drive significant long-term growth opportunities. While our current business and projected future growth are not dependent on the commercial success of these technologies, we expect they will provide incremental growth opportunities through our sales efforts and licensing arrangements with Holtec Asia. Holtec Asia currently expects to test the Holtec Green Boiler as a scale-model prototype in 2026, and we expect demonstration testing to begin on our HI-THERM HCSP following successful prototype testing of the Holtec Green Boiler. As of the date of this prospectus, the SMR-300, Holtec Green Boiler and HI-THERM HCSP have each achieved technical design, but none have been commercially deployed to date and each remain subject to successful commercialization. We also provide specialized solutions to the DOE and the DOD, while also delivering integrated security and cybersecurity solutions for critical infrastructure and data centers. We believe that our extensive footprint in the area of supply of critically important equipment and systems for Russian-origin nuclear reactors will make us an attractive partner for countries that may be wary of reliance on Russian supply chains. --- Our principal executive offices are located at 1 Holtec Boulevard, Camden, New Jersey 08104, and our telephone number at that address is (856) 797-0900.
