Shares of nuclear startup Oklo (OKLO) dropped on Tuesday after the company reported a first-quarter net loss of $33.1 million, or $0.19 per share, widening significantly from a $9.8 million loss, or $0.07 per share, in the same period last year. The loss came as the company ramped up spending on research, hiring, and project development, with no revenue generated from its reactor operations.
Spending Surge and No Revenue
Oklo's research and development costs jumped to $27.0 million, up from $7.8 million a year ago, while general and administrative expenses climbed to $24.2 million from $10.0 million. The company reported no revenue on its statement of operations, underscoring its pre-commercial stage. Operating cash burn totaled $17.9 million for the quarter, and capital expenditures for property, plant, and equipment reached $32.8 million.
Cash Pile Provides Buffer
Despite the losses, Oklo ended March with a robust balance sheet. The company held $1.59 billion in cash and cash equivalents, $614.5 million in marketable debt securities maturing within a year, and $328.3 million in longer-dated marketable debt, totaling $2.54 billion. This cash cushion was bolstered by a major share sale: Oklo sold approximately 12.4 million shares through an at-the-market program, netting $1.18 billion. Shares outstanding rose to 173.9 million from 160.5 million at the start of the year.
Regulatory Progress and AI Partnership
Oklo continues to advance its reactor ambitions. Last week, the U.S. Nuclear Regulatory Commission approved the Principal Design Criteria report for the Aurora powerhouse planned in Idaho, a key licensing milestone. On Tuesday, the company announced a Strategic Partnership Project with Battelle Energy Alliance, which operates Idaho National Laboratory, to integrate AI-driven workflows into reactor and fuel-system development. These developments support Oklo's positioning as a play on surging AI data center energy demand, even without active reactor revenue.
Market Reaction and Analyst Views
Oklo shares fell 5.7% to $73.63 in regular trading and slipped further to $71.72 after hours. The stock had rallied nearly 50% over the past month but remains about 60% below its October peak. Options markets had signaled a potential 11% swing around the earnings report. Peer pressure also weighed on sentiment: NuScale Power dropped 9.9%, and Constellation Energy fell 2.0%.
JPMorgan analyst Jeremy Tonet initiated coverage on Oklo with a Neutral rating and an $83 price target, noting the company's backlog and federal backing help it stand out in the nascent nuclear industry. However, the bank is waiting for clear signs of successful commercialization before upgrading the stock.
Key Risks Ahead
Oklo's filing highlights several uncertainties: building and deploying reactors, fuel recycling and fabrication, competition, regulatory hurdles, and securing high-assay low-enriched uranium (HALEU) or plutonium at the right price and on schedule. Any licensing or fuel delays could push back the timeline for first cash flow, increasing the likelihood of another capital raise. Management warned that building powerhouses, scaling fuel recycling, and expanding the radioisotope business will require significant ongoing investment.
For now, Oklo has cash on hand, regulatory green lights, and a new AI design partnership. But with zero revenue and escalating expenses, investors are recalibrating their expectations for this pre-revenue nuclear startup.
