OKLO Reports Q3 2025 Net Loss of $29.72 Million, Up 198.4% Year-over-Year

Oklo (OKLO.US) reported a net loss of $29.72 million for Q3 2025, a 198.4% increase compared to a net loss of $9.96 million in Q3 2024. The net loss per share was $0.20, falling short of analyst estimates of $-0.13. Total operating expenses for the quarter rose by 195.6% to $36.31 million from $12.28 million in the prior-year period.

Operating Expense Growth

Research and development (R&D) expenses increased by 195.9%, or $9.90 million, to $14.95 million in Q3 2025 from $5.05 million in Q3 2024. This rise was primarily driven by a $3.9 million increase in payroll and employee benefits due to a 60.1% increase in R&D personnel headcount and higher salaries, along with a $3.1 million increase in stock-based compensation and a $1.5 million increase in professional services.

General and administrative (G&A) expenses also saw a significant increase, rising by 195.4%, or $14.13 million, to $21.36 million in Q3 2025 from $7.23 million in Q3 2024. This was mainly attributed to a $4.4 million increase in stock-based compensation, a $1.8 million increase in payroll and employee benefits for G&A personnel due to a 92.9% increase in headcount, and a $5.9 million increase in legal and other professional fees.

Financial Position and Outlook

As of September 30, 2025, Oklo's cash, cash equivalents, and marketable debt securities totaled $1.18 billion. Despite significant operating losses, the company believes its current liquidity is sufficient to fund operations for at least one year following the issuance date of the financial statements.

The company projects its total net cash used in operating activities for 2025 to be between $65.0 million and $80.0 million. This outlook reflects ongoing significant operating expenditures necessary to implement its business plan, develop powerhouses, acquire fuel, and expand its radioisotope business.

Strategic Developments and Fuel Sourcing

Oklo highlighted several strategic milestones, including progressing regulatory approval for powerhouse deployment with both the Department of Energy (DOE) and the U.S. Nuclear Regulatory Commission (NRC). The company also continues work on fuel recycling and fabrication efforts, including a collaboration with Argonne and Idaho National Laboratory for an end-to-end demonstration of its advanced fuel recycling process.

A multi-pronged fuel strategy is being pursued to diversify and strengthen the domestic supply chain for advanced reactor fuel. This includes evaluating the potential use of alternative U.S. government fuel materials, such as plutonium, to navigate the shifting economic landscape impacted by tariffs, supply chain constraints, inflation, and evolving sanctions.
