ONE Nuclear Energy Inc. completed its business combination with Hennessy Capital Investment Corp. VII, establishing itself as a public entity focused on large-scale energy infrastructure. The combined company is scheduled to begin trading on the Nasdaq Global Market under the ticker symbol "ONEN" on or about September 24, 2026.

The transaction, approved by Hennessy VII shareholders on August 24, 2026, positions ONE Nuclear to advance its integrated platform of natural gas and advanced nuclear technologies. Richard Taylor, Co-Founder, Chairman and Chief Executive Officer of ONE Nuclear, stated that the listing provides the capital access necessary to accelerate the development of the Louisiana Portfolio and meet the growing power demands of AI and data center customers.

Portfolio composition and capacity

ONE Nuclear’s strategy combines fast-to-market natural gas generation with advanced nuclear small modular reactor (SMR) technologies. The company’s initial pipeline focuses on utility-scale projects tailored to specific customer needs and grid constraints. The 5 GW Louisiana Portfolio consists of three distinct projects designed to deliver reliable baseload power.

Strategic positioning and advisory support

The combined entity aims to address the surge in demand for reliable energy by pairing nuclear SMRs with scalable natural gas assets. Daniel J. Hennessy, Chairman and CEO of Hennessy VII, noted that the public listing enables the completion of growth plans and creates sustained value for stakeholders.

B. Riley Securities, Inc. served as the financial advisor to ONE Nuclear, while Rose & Ward PLLC and Nelson Mullins Riley & Scarborough, LLP acted as legal advisors. Cohen & Company Capital Markets served as the exclusive financial advisor and lead capital markets advisor to Hennessy VII, supported by legal counsel from Sidley Austin LLP and Appleby (Cayman) Ltd.

What the numbers show

The disclosed portfolio data reveals a strategic diversification across technology types and end-user applications. While Project Amberjack relies solely on advanced nuclear technology for up to 1 GW of capacity, Projects Cayman and Barracuda integrate natural gas generation with significant Battery Energy Storage Systems (BESS) and co-located data centers. This structure indicates a dependency on hybrid solutions to balance intermittent renewable loads or peak demands, specifically targeting the high-reliability requirements of data center operators alongside traditional utility needs.

ONE Nuclear Energy LLC secured site control for Project Cayman through a binding letter of intent with a Louisiana landowner group. The agreement enables the development of a major energy infrastructure project in the state.

The project encompasses a 2.88 GW natural gas plant and a 700 MW, 2.88 GWh Battery Energy Storage System (BESS). A high-capacity data center campus will be co-located with the energy facilities.

Strategic Location

Project Cayman is strategically located near Louisiana’s RiverPlex MegaPark, northeast of SpaceX’s recently announced infrastructure expansion. The initiative aligns with Entergy’s significant buildout of new regional transmission infrastructure, underscoring ONE Nuclear’s commitment to powering Louisiana’s expanding industrial and technology sectors.

The project will complement regional economic development efforts by adding dispatchable generation, energy storage and technology infrastructure near major new industrial loads and transmission investment, providing further regional grid reliability.

Project Details

ONE Nuclear Energy operates as an independent developer focusing on large-scale energy solutions. The company utilizes natural gas and advanced nuclear technologies for its projects.

The execution of the LOI provides the necessary site control to proceed with the development phase. The partnership with the landowner group is central to the project's advancement.

Community and Corporate Updates

Richard Taylor, CEO of ONE Nuclear, stated that the project demonstrates commitment to supporting future economic development in one of Louisiana’s most important industrial regions. He noted that the project will deliver reliable energy needed to support new investment, create jobs, expand the local tax base and generate additional funding for community priorities and critical infrastructure.

Taylor added that ONE Nuclear is proud to invest in the region to support rapidly growing energy needs created by other recently announced developments such as the SpaceX Starbase project and Hyundai’s $5.8 billion steel mill.

Community outreach is already underway and is expected to include a series of public information meetings with local parishes, governmental agencies and other project stakeholders from September through December 2026.

On August 24, 2026, ONE Nuclear’s previously announced business combination with Hennessy Capital Investment Corp. VII (NASDAQ: HVII) was approved by the Hennessy VII shareholders. The combined company is expected to be listed on a national exchange under the ticker symbol "ONEN" following an anticipated transaction close in the second half of 2026.
