AI brief of an SEC Form 8-K · DEEP FISSION, INC. (FISN)

Deep Fission signs 25-year power purchase deal for planned 150 MW Kansas project

Neutral Impact 3 of 5 product/contract Written later

Deep Fission (Nasdaq: FISN) said it signed a Master Energy Purchase Agreement with the Great Plains Development Authority for a planned commercial nuclear project at the Great Plains Industrial Park in Parsons, Kansas. The 25-year agreement converts a December 2025 letter of intent into a binding contract, but it is subject to regulatory approvals and other conditions, and it has no minimum purchase obligation, so the filing does not quantify its financial effect.

Key points

  • Binding 25-year Master Energy Purchase Agreement with the Great Plains Development Authority, replacing the December 2025 letter of intent
  • Initial phase of 150 MW with a target commercial operation date of September 30, 2028; later phases could reach 2,000 MW
  • No minimum purchase obligation; electricity purchases depend on tenant demand and are subject to regulatory approvals
  • The filing reports no revenue or financial figures for the agreement
