ONE Nuclear Energy LLC has appointed Ann Anthony as Chief Financial Officer and nominated Elizabeth Williams to its board of directors, completing its lineup of nominee independent directors. The appointments establish the company's public-company governance framework ahead of a planned business combination with Hennessy Capital Investment Corp. VII (NASDAQ: HVII), which is expected to close in the third quarter of 2026.

The combined entity plans to list on the Nasdaq exchange under the ticker symbol "ONEN" following the transaction close, subject to customary closing conditions. ONE Nuclear entered into a definitive agreement for the business combination on October 23, 2025.

Executive and Board Appointments

Ann Anthony joins ONE Nuclear from Oberon Fuels, where she served as CFO. She previously held the CFO role at OPAL Fuels Inc. (NASDAQ: OPAL), guiding the company through its de-SPAC transition and managing SEC compliance. Her background includes senior executive roles at South Jersey Industries Utilities (SJIU) and South Jersey Industries, Inc. (SJI), including Principal Financial Officer, Vice President & Treasurer, and Corporate Secretary when SJI was a $2 billion public energy holding company.

In her new role, Anthony will lead capital formation, project finance, treasury, controls, and investor relations. She holds a BS and an MBA in Finance from St. Joseph’s University.

Elizabeth Williams has been nominated as the final independent director, joining Darryl Willis, Kyle Crowley, and Dan Hennessy on the board. Williams currently serves as an Independent Board Director for Innventure (NASDAQ: INV) and Audit Committee Chair for Hennessy Capital Investment Corp. VIII (NASDAQ: HCICU). She is expected to chair the Audit Committee of the ONE Nuclear board.

Williams brings experience from roles including SVP of Strategy and Corporate Development at Tenneco, Head of Corporate Strategy (SVP) at ABB in Zurich, and VP of Corporate Strategy at Maersk. She is the Founder and Managing Partner of & Minds Partners and holds a B.A. in Economics from Stanford University and an MBA from the University of Chicago.

Other Board Nominees

The remaining independent directors nominated to the seven-member board include:

• Kyle Crowley: Formerly SVP of Corporate Finance & Development at Exelon Corporation, with $38 billion+ of transaction execution experience.
• Darryl Willis: Expected Compensation Committee Chair; Corporate Vice President, Energy & Resources at Microsoft; previously Google Cloud and BP.
• Dan Hennessy: Expected Governance Committee Chair; Managing Member of Hennessy Capital Group and a veteran public company sponsor and director.

What the Numbers Show

The appointment of Anthony, who previously managed the financial framework for a $2 billion public energy holding company at South Jersey Industries, signals ONE Nuclear's focus on scaling capital formation capabilities. This aligns with the company's need to raise additional capital to execute its business plan, a risk factor explicitly highlighted in the forward-looking statements regarding the potential unavailability of capital on acceptable terms.
