FISN Stock Forecast & Price Target

Deep Fission is attractive because it pairs proven pressurized water reactor technology with a deep-borehole design that uses 160 ATM hydrostatic pressure and surrounding geology to reduce containment complexity, capex, and surface footprint while improving safety. Its first-mover position is strengthened by selection for the DOE Reactor Pilot Program, DOE approval of the NSDA in August 2026, a completed 6,000-foot data well in May 2026, and a customer pipeline of over 18.5 GW across data centers, industrial parks, and strategic partners. Financially, the model points to ~70–80% lower construction costs versus conventional plants, ~$84M NOAK capex, roughly $20M annual revenue per reactor, and a path to first positive earnings and EBITDA in 2030, all supported by available LEU supply and policy tailwinds.

Deep Fission is fundamentally unattractive because it has no commercial revenue, no operating reactor, and is still in advanced engineering stages while facing an NRC path that may not be filed in full until late 2026. Its financial profile is deteriorating, with 2Q26 EPS of ($0.56) versus ($0.39) in 1Q26, operating expenses rising to $31.6 million, and adjusted EBITDA widening to ($24.2) million, all alongside meaningful dilution from 1.9 million RSUs and 8.1 million stock options outstanding. On top of execution risk from mile-deep drilling, site selection, and regulatory scrutiny, local environmental opposition and unresolved commercialization dependencies suggest a long, capital-intensive path with an uncertain probability of success.
