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.
