Major DOE Authorizations and Licensing Progress
Aurora-INL, Groves and A3F executed DOE Other Transaction Agreements and received Nuclear Safety Design Agreement (NSDA) approvals; A3F also received preliminary documented safety analysis (PDSA) approval and was selected under the DOE Advanced Nuclear Fuel Line Pilot Program (Oklo's PDSA was the first approved under the program). Idaho Radiochemistry Laboratory obtained its NRC materials license.
Commercial Partnership with Meta and Site Control in Ohio
Signed a prepayment agreement with Meta supporting plans for up to 1.2 GW Aurora campus in Pike County, Ohio; initial phase targeted at 150 MW around 2030. Oklo owns ~206 acres in Pike County and expects to use prepayment funds to support fuel procurement, improving project certainty.
Strong Balance Sheet and Recent Financing
Ended 2025 with $1.4 billion in cash and marketable securities and raised an additional $1.182 billion net in Jan 2026 (completing a $1.5 billion ATM), bringing pro forma cash and marketable securities to approximately $2.582 billion — an increase of roughly 84% versus year-end 2025.
Progress on Multiple Build Projects and Rapid Execution
Groves construction progressed from site to installed reactor tank in ~5 months; fuel procured and interior MEP work underway with an execution target for criticality by July 4. Aurora-INL site characterization and blasting completed, major vendors contracted (including Siemens Energy for power conversion), and long-lead procurement underway.
Strategic Vertical Integration: Power, Fuel, Isotopes
Company advanced integrated platform: power (Aurora-INL, Aurora Ohio), fuel (A3F at INL, Tennessee Advanced Fuel Center), and isotopes (Groves, Idaho Radiochemistry Laboratory). Completed acquisition of Atomic Alchemy to support VIPR/isotope roadmap and announced joint venture initiative with Centrus on deconversion.
Controlled Operational Cash Use Within Prior Guidance
Full-year 2025 cash used in operating activities was $82.2 million; after adjusting for $13 million of prepaid capital project expense, adjusted cash used in operating activities was $69.2 million, which was within the company’s 2025 guidance range of $65 million to $80 million.
Research and Fuel Development Milestones
Completed fast-spectrum plutonium criticality experiments (in partnership with Los Alamos and NNSA assets) to validate models and reduce uncertainties relevant to using plutonium as a bridge fuel; continuing engagement on potential plutonium allocations with DOE.
