    Risks & headwinds

    3
    Fuel availability for advanced nuclear deploymentNear-term to mid-term

    One of the most important gating items

    Mitigation: Oklo has spent years building differentiated capabilities and optionality, pursuing multiple fuel pathways including fresh HALEU, government surplus plutonium, and recycling. Collaborating with enrichers and leveraging AI for fuel validation.

    Regulatory timelines for nuclear licensingHistorically long

    Traditional nuclear licensing frameworks are slow

    Mitigation: Pursuing parallel DOE authorization and NRC licensing pathways. NRC modernization (Part 57, Part 53) is highly aligned with Oklo's fleet deployment model, potentially streamlining future reviews and enabling faster repeatable deployment (6-12 months target).

    PJM capacity shortfallNext decade

    Potential 50- to 60-gigawatt capacity shortfall over the next decade

    Mitigation: Oklo is progressing deployment of power assets in power park-type locations, such as Aurora-Ohio, to serve large loads and address the demand for reliable baseload power. Submitted PJM interconnection applications for Aurora-Ohio.

    Why it matters

    Successful criticality of Groves demonstrates Oklo's ability to execute on nuclear asset deployment quickly and provides valuable lessons for future projects.

    From an execution standpoint, the focus now is in final installation of reactor equipment, integrated system testing and fuel delivery with the target of July 4, 2026, criticality.

    Q&A highlights

    6

    How will Oklo source fuel for its mid-term projects like Aurora-Ohio, considering the recycling opportunity and current enrichment market?

    Oklo is pursuing a multi-pathway approach, working with enrichers and exploring government surplus materials (high-risk uranium, plutonium) as bridge fuels. They emphasize their reactor technology's flexibility to use various fuel forms (HALEU, plutonium-bearing, recycled fuel).

    “We have intentionally selected a reactor technology and an integrated sort of strategy approach that allows us to source fuel from fresh HALEU sources from government reserves that includes uranium and plutonium that can be produced into fuel that can be fueled our -- fuel our reactors as well as recycling, which can produce fuel form that can be used in our reactors.”

    Detailed Narrative

    01

    Strategic Shift to Execution

    Oklo has transitioned from strategic planning to active execution across its integrated nuclear platform, encompassing power, fuel, and isotopes. This shift is evidenced by groundbreaking on the first Aurora powerhouse, advancing major customer relationships, and making significant progress on fuel infrastructure and isotope production facilities. The company emphasizes building the platform to support deployment rather than just preparing for it.

    02

    Multi-Pathway Regulatory Approach

    Oklo is pursuing parallel regulatory pathways, utilizing DOE authorization for initial deployments like Aurora-INL to accelerate construction and procurement, while simultaneously engaging with the NRC for broader commercial licensing and future repeatability. The recent NRC Part 57 proposal, designed for faster, repeatable microreactor deployment, is seen as highly aligned with Oklo's fleet deployment model and could significantly streamline future licensing.

    03

    Fuel Optionality and Innovation

    Recognizing fuel availability as a critical gating item, Oklo has developed a multi-pronged fuel strategy. This includes progressing the Aurora Fuel Fabrication Facility (A3F) at INL, advancing the Tennessee Advanced Fuel Center for recycling, and exploring the use of government surplus plutonium as a "bridge fuel." Collaborations with NVIDIA and Los Alamos National Laboratory are leveraging AI for fuel validation, particularly for plutonium-bearing fuels, linking advanced nuclear power with AI infrastructure needs.

    04

    Power Asset Development

    The company is actively developing three key power assets: Aurora-INL (anchor deployment at Idaho National Laboratory), Aurora-Ohio (a planned 1.2 GW advanced nuclear power campus with Meta, for which PJM interconnection applications have been submitted), and Aurora-Eielson (a cogeneration project for Eielson Air Force Base in Alaska, focusing on heat and power for resilience). These projects demonstrate diverse applications for Oklo's technology.

    05

    Isotope Business Progress

    Oklo's isotope business is moving towards near-term operations and commercial activity. The Groves test reactor facility achieved substantial construction completion in just 229 days, targeting criticality by July 4, 2026. The Idaho Radiochemistry Laboratory, an NRC-authorized facility, has secured a material handling permit and is advancing its first commercial isotope contract, aiming for revenue generation in 2026. This vertical integration supports high-value domestic market sectors like space, defense, industrial, and healthcare.

    06

    Strengthened Financial Position and Board Expansion

    Oklo ended Q1 FY26 with a strong balance sheet, holding $2.5 billion in cash and marketable securities, significantly bolstered by $1.2 billion generated from its ATM program. The company also expanded its Board of Directors with experienced leaders from energy, industrial, infrastructure, finance, and technology sectors to support the scaling and complexity of its vertically integrated business.
