FISN Stock Forecast & Price Target

Deep Fission is attractive because it combines proven pressurized water reactor technology with a deep-borehole design that can cut containment, cooling, and surface-infrastructure costs while improving safety through natural hydrostatic pressure and geological shielding. Its early execution has de-risked the story, with DOE Reactor Pilot Program selection, an approved NSDA, a completed 6,000-foot data well in May 2026, and non-binding LOIs representing up to 18.5 GW of demand from data centers, industrial parks, and partners. Financially, the company has raised $27.1 million in the September 2025 APO, $76.0 million in February 2026 private placement, and $34.4 million in June 2026 financing, while management’s model points to ~$80 million per reactor, about $20 million annual revenue per unit, and first positive earnings and EBITDA in 2030.

Deep Fission is burdened by a pre-revenue profile, widening losses, and heavy cash burn, with 2Q26 EPS of ($0.56), operating expenses of $31.6 million, and Adj-EBITDA of ($24.2) million, all while the company still needs additional capital to fund its borehole program and pilot reactor. Its Gravity Reactor remains highly speculative because commercialization depends on NRC approval, binding power agreements, and solving unusually difficult drilling, maintenance, corrosion, and site-selection risks in a mile-deep borehole where limited test-scale proof is no guarantee of scalable execution. Even under optimistic models that assume initial revenue in 2H27 and profitability in 2030, free cash is still expected to stay negative, while a $80 million capital cost per reactor and a market that has not yet been established leave the equity exposed to financing and dilution risk.
