Year-to-date cash used in investing activities of $912.7 million, including $743.6 million for purchases of marketable securities and $126.9 million in capital expenditures across all three business lines.
$1.9 billion in additional capital generated from execution of ATM (at-the-market) programs during 2026.
Business Segment Results
Power segment: Aurora-INL advanced through DOE authorization and construction with preliminary documented safety analysis (PDSA) approval; Aurora-Ohio entered execution phase with Memorandum of Understanding with Kiewit for engineering, procurement, and construction planning; Eielson Air Force Base project developing Aurora application for electricity and heat delivery.
Fuel segment: Aurora Fuel Fabrication Facility equipment in production supporting planned 2027 installation and startup; Advanced Fuel Center in Tennessee progressing on facility engineering, NRC license application readiness, and civil engineering; Centrus letter of intent supporting domestic HALEU supply for up to five Aurora powerhouses with deliveries expected in 2029.
Isotopes segment: Groves facility achieved first criticality in early August 2026, representing the fastest transition from greenfield to criticality for a privately-funded reactor in history at approximately 11 months from groundbreaking; Idaho Radioisotopes Laboratory NRC-licensed and supporting initial commercial isotope activities.
Capital Allocation
Capital expenditures increased to $400-500 million range for full-year 2026, compared to prior guidance of $350-450 million, driven by accelerated procurement and construction at Aurora-INL and opportunistic fuel purchases.
Operating cash usage guidance updated to $120-150 million range from prior guidance of $80-100 million, reflecting first-of-a-kind project costs at Aurora-INL, grid interconnection build-out, and acceleration of early-stage deployment costs.
Strategic acquisitions of ARMEC and Creative Engineers during the quarter to strengthen internal manufacturing, engineering, and specialized systems capabilities for repeatable deployment across business lines.
Capital deployment prioritized for long lead-time procurement items and grid interconnection work to ensure project delivery and mitigate supply chain constraints.
Industry Trends and Dynamics
DOE Genesis Mission creating sizable opportunity for advanced nuclear projects, with $800 million in mission-wide partner commitments announced; Oklo selected for $60 million Phase 2 award over three years for Prometheus project.
Nuclear Lifecycle Innovation Campus (NLIC) initiative selecting five states (Utah, Tennessee, Oklahoma, Louisiana, and Idaho) as potential hosts for integrated fuel fabrication, enrichment, recycling, reactor development, and power generation ecosystems.
Strong customer demand for advanced nuclear power, with management describing demand as "unconstrained" and noting that regulatory deconstraining, fuel availability, and procurement-construction capabilities are key supply-side constraints.
Data center and hyperscaler demand driving significant growth opportunity for nuclear power, with management noting increased community engagement and policy support for nuclear energy in data center applications.
Competitive Landscape
Oklo positioned as central participant in DOE initiatives through collaborations with NVIDIA, Los Alamos National Laboratory, and participation in multiple Genesis Mission projects.
Distinctive integrated platform strategy differentiating Oklo from competitors through vertical integration across power, fuel, and isotopes rather than isolated business lines.
Execution capability as competitive advantage, with Groves representing the fastest privately-funded reactor transition to criticality, demonstrating organizational infrastructure for repeatable nuclear asset deployment.
Build, own, and operate model allowing Oklo to retain operating experience, procedures, and execution knowledge that competitors relying on third-party operators cannot capture.
Macroeconomic Environment
No specific macroeconomic headwinds discussed in the earnings call; management focused on regulatory and supply-side constraints rather than demand-side economic concerns.
Policy support for advanced nuclear through DOE initiatives and NLIC campus development, indicating favorable regulatory and political environment for nuclear deployment.
Growth Opportunities and Strategies
Integrated nuclear technology platform combining power generation, fuel sourcing/fabrication/recycling, and isotope production to create a flywheel effect supporting fleet deployment.
Diversified fuel strategy utilizing commercial HALEU from Centrus, government surplus plutonium materials, EBR-II used fuel, and future recycling capabilities to eliminate fuel as a deployment constraint.
AI and advanced computing integration through Prometheus project and NVIDIA collaboration to accelerate fuel validation, design workflows, and operational optimization; management noted design work previously requiring months now completed in hours.
Multi-state deployment strategy with Aurora-INL as anchor project, Aurora-Ohio 1.2-gigawatt clean energy campus for phased multi-powerhouse deployment, and Eielson Air Force Base defense application.
Isotope production expansion with Groves providing full-scale deployment model for future isotope facilities and Idaho lab supporting near-term commercial isotope activities.
Partner capital opportunities emerging through customer prepayments (Meta, Equinix) and potential third-party investment in fuel infrastructure and NLIC campus projects.
Financial Guidance and Outlook
2028 startup target maintained for Aurora-INL despite increased capital spending, with acceleration of long lead-time procurement and grid interconnection work to ensure critical path achievement.
Aurora Fuel Fabrication Facility startup planned for 2027 to support fuel fabrication for first Aurora core load.
Centrus HALEU deliveries expected to begin in 2029 under letter of intent supporting multiple years of initial core and reload needs for up to five Aurora powerhouses.
Isotope revenue expected primarily from Idaho lab facility in near term rather than Groves reactor, with commercial discussions ongoing and first revenue likely in first part of 2027.
Plutonium fuel allocation timeline uncertain but described as "closer than we were," with final DOE agreement, safeguards, and material allocation still pending.
No specific full-year revenue or earnings guidance provided; management indicated they would provide tighter cost guidance for Aurora-INL and future projects as planning advances through remainder of 2026.
Execution and Operational Achievements
Groves facility completed substantial construction in 229 days and reached first criticality in less than one year after groundbreaking, representing record-setting pace for nuclear industry.
Full-scale private deployment model demonstrated with Groves built on private land, financed with private capital, and featuring commercially sourced major systems, components, and fuel.
Organizational infrastructure developed in-house including site development, permitting, safety basis, quality assurance, security programs, operating organization, procurement, and project controls.
DOE authorization pathway successfully navigated with Groves becoming first Reactor Pilot Program reactor to achieve criticality on privately-owned greenfield site.
Reusable execution capabilities established for future isotope facilities, Aurora powerhouses, and fuel fabrication/recycling assets through lessons learned and procedures retained within Oklo.
