OKLO Earnings Recap
Beat 2 of last 7 quarters
The Buildout is a website built on agentic AI tools, currently in beta, and could have factual errors.
Oklo's Groves criticality demonstrates the ability to deploy nuclear assets rapidly on private land, a key proof point for the AI infrastructure buildout's need for firm power. The company's expanded fuel strategy (Centrus HALEU, plutonium, recycling) addresses a critical supply chain constraint for advanced nuclear, potentially accelerating deployment for data center customers like Meta. The raised guidance signals increased near-term capital deployment into first-of-a-kind projects, reinforcing the buildout's momentum.
Oklo achieved first criticality at its Groves radioisotope reactor, completing the fastest greenfield-to-criticality transition for a privately funded reactor in history. The company advanced Aurora INL with DOE approval of the Preliminary Documented Safety Analysis and near-complete excavation, and signed an MOU with Kiewit for the Ohio campus. Acquisitions of ARMEC and Creative Engineers strengthened manufacturing and sodium systems capabilities. The company ended Q2 with $3.0B in cash and marketable securities, and raised its 2026 cash flow guidance to reflect accelerated project spending.
Management discussed the integrated platform across power, fuel, and isotopes, emphasizing that Groves provides reusable execution capabilities. They noted that Aurora INL remains on track for 2028 start-up, with PDSA approved and excavation near complete. Fuel strategy is diversified across Centrus HALEU (LOI for up to 5 powerhouses, deliveries from 2029), DOE surplus plutonium (advanced negotiations), and EBR-II recycled fuel (A3F equipment in production, 2027 installation). They expect first isotope revenue from the Idaho lab in early 2027, with Groves producing R&D quantities in about 12 months.
“We are not only funding studies or developing designs for others to build. We are building and operating nuclear assets, and we are doing it at a pace that many people did not believe was possible.”
on Execution and Groves criticality
“We are not relying on a single supplier, a single feedstock or a single part of the fuel cycle. We are advancing multiple complementary pathways across commercial HALEU, government materials and recycling.”
on Fuel diversification strategy
“Given the strength of our balance sheet and ongoing capital raise activity, we chose to spend opportunistically rather than allow procurement timing to potentially put project delivery at risk.”
on Capital deployment and guidance raise
Can you update us on the timeline for plutonium allocations and how the measured reactivity coefficients compare to models with the delayed neutron fraction below U-235?
Jake noted DOE allocations are still developing, with ~20 tons total to be divided among recipients. He described the Flattop campaign at Los Alamos, where the fast plutonium system showed strong reactivity feedback, heating up until it turned itself off by thermal expansion. He emphasized the system's responsiveness and stability, calling it 'like a perfectly tuned and engineered sports car.'
Could you provide an update on the radioisotope production roadmap at Groves, which isotopes are prioritized, and when you anticipate first revenue?
Jake said Groves is a full-scale isotope reactor and they will go through commissioning over the next year, with R&D quantities of material expected in about 12 months. Craig added that first revenue is more likely from the Idaho lab in early 2027, with commercial discussions ongoing.
Is the plan to go to blended plutonium after the initial EBR-II loads, or will Centrus come online before that?
Jake explained a multi-pronged fuel strategy: first reactor uses EBR-II recovered material, scaled up with plutonium blended fuel as a bridge, then Centrus HALEU, and eventually recycling. He emphasized the versatility of fast reactors to use diverse fuel sources, calling it an 'enduring advantage.'
