Oklo remains a pre-revenue, development-stage nuclear company and reported a first-quarter net loss of $33.1 million, including a $51.2 million loss from operations, a wider loss year-over-year as it scales investment across power, fuel and isotopes. The company ended the quarter with $2.5 billion of cash and marketable securities after raising an additional $1.2 billion through a completed ATM program, funding $359 million of investing cash use and $32.8 million of capital spend. Management reiterated 2026 guidance for $80 million to $100 million of operating cash use and $350 million to $450 million of PP&E investing cash use, both spend metrics rather than growth guidance. Operationally, the quarter emphasized execution: the Groves test reactor was built in 229 days and targets criticality by July 4, a first commercial isotope contract is pending with early revenue expected in 2026, and management pointed to regulatory momentum in the NRC's proposed Part 57 and government surplus plutonium as a bridge fuel. The thesis is deployment progress and a fortified balance sheet, but Oklo is still ahead of any commercial power revenue.
