2026 guidance for capital deployment: Expected cash used in operating activities of $80 million to $100 million and cash used in investing activities for property, plant, and equipment deployment of $350 million to $450 million.
Industry Trends and Dynamics
US nuclear tailwinds shifting from policy endorsement to execution across power markets, fuel recycling, space travel, and exploration.
White House launched National Initiative for American Space Nuclear Power, with DOE directed to assess readiness for up to four space reactors within five years.
PJM continues to highlight need for new firm supply, including bridging a potential 50- to 60-gigawatt capacity shortfall over the next decade and proposing a Reliability Backstop Procurement framework.
DOE issued requests for applications to advance privately funded used nuclear fuel recycling, while states increasingly compete to host integrated nuclear campuses.
NRC modernization advancing through Part 53 and Part 57, with Part 57 proposing fleet-based licensing and standardized reviews for smaller, repeatable reactors with targeted licensing and deployment timelines of 6 to 12 months.
Demand continues to build for reliable baseload power to support data centers, industrials, energy, and government customers.
Competitive Landscape
Oklo positions itself as differentiated by the combination of advanced nuclear power, fuel and fuel recycling, isotopes, and a vertically integrated business model.
Company emphasizes its unique ability to source fuel from fresh HALEU sources, government reserves including uranium and plutonium, and recycling, capabilities not available across all reactor types.
Oklo has advanced major customer relationships, including Switch and Meta, with Meta partnership for 1.2-gigawatt power campus in Ohio.
Macroeconomic Environment
Nuclear increasingly viewed as strategic infrastructure beyond the grid, beyond the planet, and beyond the century.
Growing recognition of used fuel as strategic domestic energy resource rather than a liability.
Significant uptick in government opportunities for making excess materials available, including high enriched uranium recovery and plutonium inventories.
Growth Opportunities and Strategies
Vertically integrated platform strategy connecting fuel fabrication, power production, fuel recycling, and isotope production into an integrated loop where power creates fuel demand, recycling supports long-term supply, and recovered materials support isotope opportunities.
Multiple fuel pathway strategy to support deployment while reducing reliance on any single fuel source, including fresh HALEU, government reserves, and recycling.
Plutonium-based fuel bridge strategy leveraging 20 tons of government-available plutonium equivalent to 160-200 tons of HALEU to accelerate reactor deployment.
AI-enabled design acceleration through partnerships with Battelle Energy Alliance and INL for agentic AI workflows in reactor design, and with NVIDIA and Los Alamos for plutonium fuel validation.
Repeatable deployment model with multiple powerhouse and campus-style development approach, supported by NRC Part 57 fleet-based licensing framework.
Isotope business expansion into high-value domestic market sectors for space, defense, industrial, and healthcare applications.
Defense and co-generation applications through Aurora-Eielson project demonstrating distributed nuclear for mission-critical defense operations with heat resilience and energy security.
Financial Guidance and Outlook
2026 cash flow guidance: Operating cash burn of $80 million to $100 million and capital expenditure deployment of $350 million to $450 million.
Strong balance sheet positioning with $2.5 billion in cash and marketable securities providing resources to benefit from policy and regulatory tailwinds and execute business plans in 2026 and beyond.
Company trending toward guided ranges for 2026 with continued focus on accelerating procurement and construction efforts.
Regulatory and Licensing Strategy
Parallel regulatory pathways approach using DOE authorization to advance first asset while continuing NRC work supporting broader commercial licensing and future repeatability.
NRC Principal Design Criteria topical report approval for Aurora-INL establishes fundamental safety, reliability, and performance requirements and clears path for future applications.
Part 57 expected implementation timeline of later in 2026, providing performance-based regulatory framework aligned with Oklo's fleet deployment model.
DOE authorization pathway advantages allowing continued advancement of construction, procurement, and system integration while project moves through authorization.
Operational Execution and Asset Development
Groves reactor construction completed in 229 days, demonstrating that nuclear assets can move faster than traditionally expected with right design, scope, supply chain, and authorization pathway.
Groves targeting July 4, 2026 criticality with focus on final installation of reactor equipment, integrated system testing, and fuel delivery.
Aurora-INL site execution advancing with transition to deep-foundation excavation, long-lead procurement work, and supplier engagement for reactor module and balance of plant.
Board strengthened with experienced directors including Michael Thompson as lead independent director and new directors Mark Peters, David Christian, Derek Kan, and David Park bringing expertise in executing complex technical projects.
