Deep Fission (FISN) Corporate presentation summary

Technology and innovation

• Developing a nuclear reactor designed for deployment one mile underground, integrating mature PWR, deep borehole drilling, and geothermal technologies to reduce surface infrastructure and enhance safety, security, and cost efficiency.

• Gravity Nuclear Reactor leverages hydrostatic pressure from a deep water column for natural pressurization and uses standard low-enriched uranium fuel.

• Holds two issued U.S. patents and 38 pending applications covering unique borehole reactor architecture and deployment methods.

Commercialization and deployment

• Commercial pilot project underway at Great Plains Industrial Park, Kansas, with drilling and engineering milestones achieved and a target for commercial operation in 2027-2028.

• Secured non-binding LOIs for up to 18.5 GWe of generation capacity, including partnerships with data center and infrastructure companies.

• Business model includes revenue from reactor delivery, licensing, electricity sales, and long-term operations and maintenance.

• Strategic relationships established with Blue Owl, Endeavour, and Great Plains Development Authority for project development and financing.

Market opportunity and regulatory environment

• U.S. data center and AI-driven power demand expected to outpace supply, creating urgent need for scalable, dispatchable, zero-carbon energy.

• Engaged in parallel regulatory pathways with DOE and NRC, with proactive safety analysis and licensing processes to accelerate deployment.

• Targeting high-volume commercial licensing for clustered reactor deployments at single and multiple sites.
