General Fusion Announces Major Milestone: SPAC Merger and Acceleration Toward Commercial Fusion Energy

Key Highlights from the Investor Presentation

• General Fusion Inc. (“General Fusion”) is set to merge with Spring Valley Acquisition Corp. III (“Spring Valley”) via a SPAC transaction, targeting rapid commercialization of fusion energy solutions.
• The company has built and is operating a large-scale demonstration machine (Lawson Machine 26, “LM26”), a significant step toward achieving fusion energy at a commercially relevant scale.
• The transaction values General Fusion at a \$600 million pre-money valuation, with an implied pro-forma enterprise value of \$724 million and an expected equity value of \$1.038 billion.
• General Fusion has raised over \$400 million to date and secured \$108 million in a preferred equity PIPE at \$12.00 per share, with additional capital expected from the SPAC trust.
• The company is one of only four private companies worldwide with published, peer-reviewed fusion results on the path to the Lawson criterion, with 35 publications and 210 patents issued or pending.
• General Fusion’s Magnetized Target Fusion (MTF) technology is designed to be cost-competitive, scalable, and integrates into existing power plant infrastructure, targeting a levelized cost of energy (LCOE) between \$64–\$73/MWh for nth-of-a-kind plants.
• The leadership team brings over 100 years of collective C-suite experience, with a strong track record in energy, decarbonization, IPOs, and SPAC transactions.

Details of the SPAC Transaction

• Sources & Uses:
  • General Fusion shareholders are expected to hold approximately 58% of the pro-forma equity.
  • PIPE investors will own 13.6%, SPAC shareholders 22.2%, and the SPAC sponsor 6.4% of the new entity.
  • The PIPE proceeds and cash from the SPAC trust will fund the LM26 program, commercial systems development, and the first-of-a-kind (“FOAK”) plant for commercial deployment.
• Valuation Metrics:
  • Share price at \$10.00 with 103.8 million shares outstanding.
  • Equity value: \$1.038 billion; Enterprise value: \$724 million (post-transaction).
  • Excludes \$135 million earnout and the impact of private placement/public warrants, convertible preferred warrants, and any equity compensation plans.
• Market Opportunity:
  • General Fusion targets the rapidly growing market for clean, reliable baseload energy—estimated at over \$1 trillion annually by 2050 for fusion, with wind, battery, and solar markets collectively exceeding \$860 billion by 2034.
  • The company’s MTF approach is positioned to overcome critical barriers such as fuel sourcing, material degradation, energy capture, and cost, making commercial fusion power a realistic near-term possibility.

Commercialization Pathway and Technical Milestones

• General Fusion’s Lawson Machine 26 (LM26) program is underway, with the demonstration machine assembled and operational since December 2024.
• First plasma was achieved in February 2025, with initial plasma compressions in April 2025. The company is now advancing toward key technical milestones:
  • Achieving plasma temperatures of 1 keV (~10 million °C) and 10 keV (~100 million °C).
  • Simultaneous demonstration of temperature, density, and energy confinement time to achieve 100% Lawson criterion (“break-even” for D-T plasma).
• Commercial system validation and demonstration are targeted for the late 2020s, with the first FOAK plant and sales of commercial fusion powerplants expected to begin thereafter.
• Key partnerships with major automakers, Oak Ridge National Laboratory, Princeton Plasma Physics Laboratory, Lawrence Livermore National Laboratory, and others, are accelerating technology and market adoption.
• General Fusion’s MTF technology is designed for rapid, scalable deployment, with the potential to retrofit existing coal-fired powerplants and integrate seamlessly with current grid infrastructure.

Strategic, Regulatory, and Financial Considerations

• Regulatory Tailwinds:
  • The 2024 ADVANCE Act created a new, streamlined regulatory framework in the U.S. for fusion energy, separating it from the legacy fission nuclear rules, and reducing expected regulatory burdens and export controls.
  • Global government support is increasing, with the U.S., EU, UK, Germany, and G7 all committing significant funding and policy support to fusion energy commercialization.
• Competitive Positioning:
  • General Fusion claims several advantages over competing fusion approaches, including the ability to breed tritium fuel within the plant, use existing materials (avoiding the need for superconducting magnets or high-powered lasers), and deliver cost-competitive energy without long-lived radioactive waste.
  • The company’s asset-light, scalable business model envisions acting as a high-margin OEM and technical service provider, partnering with EPCs and power plant owners/operators for construction and long-term operations.
• Risks and Forward-Looking Statements:
  • Completion of the business combination is subject to regulatory approval and shareholder votes.
  • Execution risk remains in technology scale-up, regulatory compliance, and capital raising, including the proposed PIPE financing.
  • The company’s commercialization pathway and financial projections are based on management estimates and subject to change depending on market, technical, and regulatory developments.

Shareholder Considerations and Potential Price-Sensitive Information

• Shareholders should note the following potentially price-sensitive developments:
  • The successful completion of the SPAC merger and PIPE financing will significantly strengthen General Fusion’s balance sheet and accelerate its commercialization timeline.
  • Achievement of the key technical milestones (e.g., 1 keV, 10 keV, and 100% Lawson) will serve as major de-risking events and could materially influence the company’s valuation.
  • General Fusion’s competitive LCOE estimates, partnership announcements, and regulatory support could all act as catalysts for share price movement.
  • Any delays or setbacks in the LM26 program, failure to secure additional capital, or changes in regulatory outlook could adversely affect the share price.
• Investors are urged to review the registration statement, proxy statement, and other filings for full details and to monitor for future updates as the business combination progresses.

Conclusion: Game-Changing Potential for Clean Energy Investors

General Fusion’s unique engineering approach, strong IP portfolio, global partnerships, and favorable regulatory momentum position the company as a leader in the race to commercial fusion energy. The successful execution of the SPAC merger, ongoing technical validation, and scaling of operations have the potential to be transformative for the company and the broader energy sector. Investors should closely monitor upcoming milestones and regulatory developments, as these will be critical to the company’s future valuation and market position.
