## Deep Fission's Binding Kansas Agreement

The Great Plains Development Authority is a quasi-municipal entity that owns the Great Plains Industrial Park in Parsons, Kansas. The contract converts the parties' December 2025 letter of intent into a definitive agreement for a commercial project at the site of Deep Fission's Department of Energy pilot. Deep Fission is bound to pursue the project and to supply power once licensed and operating, subject to the agreement's terms and conditions.

Under the agreement, the authority will purchase electricity generated and made available by Deep Fission to satisfy the electricity requirements of industrial park tenants, up to the contracted capacity, with no minimum purchase obligation. The authority may also assign its purchase obligations to qualifying tenants.

"This agreement turns a shared vision into a binding commitment," said Liz Muller, CEO and Co-Founder of Deep Fission. "Our approach is to bring firm power directly to where it's needed."

Brad Reams, Park Director at the Great Plains Development Authority, said dependable, affordable power draws employers to Southeast Kansas. The park covers more than 14,000 acres in Labette County on the site of a former U.S. Army ammunition plant, with existing rail access, utilities and space for large industrial users. Deep Fission held a groundbreaking ceremony at the park in December 2025 on its pilot reactor under the DOE Reactor Pilot Program.

## Deep Fission's Funding and Partnerships

Deep Fission is a pre-revenue advanced nuclear energy company developing the Gravity Nuclear Reactor, a small modular pressurized water reactor designed for installation approximately one mile underground in deep boreholes, according to akta.pro [company records](https://akta.pro/company-data). The company completed an IPO of 2.5 million shares at $16.00 on Nasdaq under ticker FISN, raising $40 million in gross proceeds, and signed a partnership with Day & Zimmermann to oversee pre-construction planning and above-ground construction of the Gravity reactor at the Great Plains Industrial Park. Deep Fission also signed a fuel purchase agreement with Urenco USA in February 2026 for low-enriched uranium to support testing, demonstration activities and early commercial operations.

## Deep Fission's Path to the Parsons Contract

Deep Fission announced the pricing of its public offering of 2.5 million shares at $16 per share, raising $40 million in gross proceeds, in September 2026, according to FinancialContent Business Page. In August 2026, The Times of India reported that Deep Fission is developing an underground nuclear reactor in Kansas, targeting a 5-MW pilot installation by late 2027 using established pressurized-water-reactor technology deployed via deep boreholes. AInvest reported in August 2026 that Deep Fission failed to meet a July 2026 criticality milestone under the Department of Energy's Reactor Pilot Program and must await finalization of the NRC's Part 57 licensing framework.
