2Strategic Updates and Business Highlights

Project Genesis Participation: Oklo is involved in the DOE's Genesis mission, receiving a $60 million Phase I award for the Prometheus project, focusing on AI applications in nuclear fuel validation and reactor design.

Nuclear Life Cycle Innovation Campuses: Five states selected for potential campuses to enhance nuclear fuel lifecycle management, with Oklo actively engaging with these states.

Integrated Nuclear Technology Platform: Oklo is building a vertically integrated model encompassing power, fuel, and isotopes, aiming for greater operational efficiency and capital flexibility.

Groves Reactor Milestone: Achieved first criticality at the Groves facility, marking the fastest transition from greenfield to operational reactor in history.

Acquisitions: Strengthened capabilities through the acquisition of ARMEC and Creative Engineers, enhancing engineering and manufacturing capabilities.

3Forward Guidance and Outlook

Project Timelines: Aurora INL is on track for a planned start-up in 2028, with ongoing procurement and construction activities.

Fuel Strategy: A diversified approach to fuel sourcing, including HALEU from Centrus and potential plutonium allocations, is expected to support future deployments.

Revenue Expectations: First revenue from the isotope business anticipated in early 2027, primarily from the Idaho radiochemistry lab.

4Bad News, Challenges, or Points of Concern

Increased Cash Burn: The updated cash flow guidance reflects higher project costs and operational expenses, which could impact liquidity if not managed effectively.

Execution Risks: While the Groves reactor's success is a positive indicator, future projects will still face unique execution challenges, including regulatory approvals and supply chain constraints.

Fuel Supply Uncertainty: While Oklo has multiple fuel pathways, reliance on government allocations for plutonium and the timing of HALEU availability remain potential risks.

5Notable Q&A Insights

Plutonium as Bridge Fuel: Discussions highlighted the potential of blending plutonium with uranium for HALEU equivalent fuel, but concerns about the limited inventory and long-term sustainability were noted.

Isotope Production Roadmap: Initial production expected within 12 months, with revenue likely coming from the Idaho lab before scaling up at Groves.

Interconnection Challenges: Oklo is actively managing PJM interconnection applications, but potential delays in the interconnection process could impact project timelines.

Customer Confidence: The company noted that different customers prioritize various factors (regulatory, fuel availability) in their decision-making, with a trend towards recognizing the importance of a diversified fuel strategy. Overall, Oklo is demonstrating significant progress in its strategic initiatives and operational capabilities, although it faces challenges related to cash flow management and execution risks in future projects.
