Oklo Inc. filed an amended quarterly report for the period ended March 31, 2026, solely to correct the conformed signature on the CFO’s certification; the underlying financial and other information remains unchanged from the original filing.
For the quarter, Oklo reported a net loss of $33.1 million, or $0.19 per share, as it continues to invest heavily in developing advanced fission powerhouses, fuel recycling, and radioisotope production. Research and development expenses rose to $27.0 million and general and administrative costs to $24.2 million, reflecting headcount growth and higher stock-based compensation.
Despite ongoing losses, Oklo’s liquidity strengthened significantly, with $2.54 billion in cash, cash equivalents, and marketable debt securities and $2.70 billion in total assets, largely driven by raising about $1.18 billion of net proceeds through an at-the-market equity program. The company expects its current cash resources to fund operations for at least one year while it advances key regulatory milestones, fuel facilities, and customer agreements for its Aurora powerhouses and isotope business.
