Oklo 10-Kyear ended 2025-12-31

Executive Summary

Oklo is financing the development of small nuclear powerhouses and related fuel and radioisotope businesses, but FY2025 delivered no revenue and no operating reactor. Equity raises lifted year-end cash and marketable securities to $1.41B, while operating losses, cash use and construction spending accelerated. Government program selections and a subsequent agreement with Meta advance the potential project pipeline; neither resolves the need for licenses, dependable fuel supply and economically viable construction. For investors, the thesis is a well-funded but highly dilutive path to commercialization, not a near-term earnings story.

Key Financial Highlights

• Spending: Research and development rose 120% to $58.9M; general and administrative expense rose 208% to $80.4M. Hiring, professional services and stock-based compensation drove the increases.
• Earnings quality: OCF exceeded the $(106)M net loss primarily because expenses included noncash stock-based compensation of $41.8M, up from $12.5M; capital expenditures rose to $33.2M. Interest and dividend income increased to $29.1M as financing proceeds were invested, while a $27.9M fair-value loss recorded in FY2024 did not recur.
• Funding and dilution: Financing cash provided was $1.26B, chiefly from share offerings. Shares outstanding increased 16.6%, from 137.7M to 160.5M; the $1.5B December at-the-market program remained open at year-end. Subsequent sales through 1/28/2026 generated $1.20B gross from another 12.4M shares.

Business Developments

Oklo intends to design, own and operate Aurora reactors, initially targeting 15–75 megawatts of electric capacity, and sell power directly to customers. That model could produce recurring revenue but places construction, financing and operating risk on Oklo. Management targets its first Idaho powerhouse in 2028. The project advanced through Department of Energy site and licensing steps, but the company had not submitted its updated custom license application to the Nuclear Regulatory Commission as of the filing.

Customer interest spans data centers and other power users. The 12-gigawatt Switch master agreement and other preliminary arrangements do not establish operating capacity or recurring sales. On 1/5/2026, Oklo entered a prepayment agreement with Meta to advance a planned 1.2-gigawatt Ohio campus; the summarized filing gives no prepayment amount. Converting such arrangements into binding, financeable projects is the commercial test.

Oklo is also investing in fuel fabrication and recycling to address a potential constraint on reactor deployment. Its planned Tennessee fuel center has a roadmap of up to $1.68B in investment. The February 2025 acquisition of Atomic Alchemy adds radioisotope development; it contributed no revenue in FY2025. These initiatives broaden possible revenue sources, but compete for capital and execution capacity before the first power sale.

Risk Assessment

• Licensing and first deployment: No planned powerhouse has approval to operate, and Oklo’s earlier federal license application was denied without prejudice in 2022; review, construction or commissioning delays could push out the 2028 target.
• Fuel availability: Commercial-scale supply of the specialized fuel envisioned for Aurora is not established, so fuel shortages or higher costs could constrain deployment even if reactors are licensed.
• Project economics and financing: First-of-a-kind construction costs have risen from earlier estimates; simultaneous reactor and fuel projects could require substantial additional capital before revenue, with further issuance diluting shareholders.
• Customer conversion: Preliminary agreements, options and letters of intent may not become binding power purchases; customer demand and pricing also depend partly on sustained data-center growth.
• Supply chain and operations: Reliance on specialized contractors, equipment and new facilities exposes schedules and costs to capacity limits, inflation and design changes.
• Acquired-asset valuation: $27.5M of indefinite-lived in-process research and development and $6.62M of goodwill depend on successful development; setbacks could trigger impairment.

Strategic Outlook and Investor Actionables

Management expects FY2026 cash used for operating expenses of $80–$100M and investing activities of $350–$450M. The expanded cash position buys development time, but the investment case depends on turning regulatory progress and customer commitments into deployable plants at supportable costs.

• Licensing and schedule: Track the updated federal license submission and Idaho authorization milestones; missed steps would weaken the 2028 deployment target.
• Commercial conversion: Track binding power agreements, disclosed Meta project terms and committed capacity—not preliminary pipeline announcements.
• Cash and dilution: Compare actual operating and investing cash use with FY2026 expectations, alongside new shares issued and evidence that construction and fuel commitments are becoming financeable.
