Deep Fission Shares Rise After Master Energy Purchase Agreement

By Chris Wack

Deep Fission shares rose after the company said it entered into a master energy purchase agreement with the Great Plains Development Authority, a quasi-municipal entity that owns the Great Plains Industrial Park in Parsons, Kansas.

The stock was 6% higher, at $3.88, in morning trade, and is down 62% in the past three months.

The company said the agreement converts the parties' December 2025 letter of intent into a definitive contract for a commercial project at the site of Deep Fission's Department of Energy pilot.

The agreement binds Deep Fission to pursue the project and to supply power once licensed and operating, subject to the agreement's terms and conditions. Under the agreement, the Great Plains Development Authority will buy 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 agreement also permits the Great Plains Development Authority to assign its purchase obligations to qualifying tenants.

The initial phase is anticipated to be 150 MW with a target date of commercial operation on Sept. 30, 2028, and grow through later phases to a total of 2,000 MW pending further demand growth.
