Welcome to our dedicated page for Oklo SEC filings (Ticker: OKLO), a comprehensive resource for investors and traders seeking official regulatory documents including 10-K annual reports, 10-Q quarterly earnings, 8-K material events, and insider trading forms.
Oklo Inc. (OKLO) SEC filings document the regulatory record of an advanced nuclear technology company developing fast fission power plants, nuclear fuel recycling and critical isotope supply. For Oklo, quarterly reports and amended quarterly reports are useful for reviewing operating updates, capital-structure disclosure, risk factors and the company’s description of its nuclear development activities.
Oklo’s Form 8-K filings are especially relevant because the company’s business can be affected by material agreements, financing arrangements, officer and director changes, shareholder voting results and other reported events. Recent 8-K categories include material definitive agreements, governance matters and annual meeting results. These filings help investors separate company-disclosed events from general market commentary about advanced nuclear power.
Annual reports, quarterly reports and proxy statements can also show how Oklo explains its business model, emerging growth company status, governance structure, executive compensation framework and stockholder voting matters. The company’s proxy materials and meeting-result filings provide details on board elections, auditor ratification and other shareholder matters.
For OKLO stock research, the most relevant filing types include Form 10-K for annual business and risk disclosure, Form 10-Q for quarterly updates, Form 8-K for material events, and DEF 14A proxy statements for governance and compensation information. These documents are central to understanding Oklo’s public-company obligations as it works on Aurora powerhouse commercialization, fuel recycling and isotope-related projects.

The Sales Agreement permits sales from time to time through brokers, market makers, the NYSE, private negotiated transactions, block trades, or forward sale structures (including range and collared forwards). The offering proceeds will be used for general corporate purposes, working capital, capital expenditures, and potential investments.

Oklo Inc. entered into a new equity distribution agreement with a syndicate of investment banks to sell, from time to time, up to $1,000,000,000 of Class A common stock through an at-the-market offering program. Sales may be made on the New York Stock Exchange and other permitted venues at market or negotiated prices, with the company paying up to 1.5% in sales commissions.
Oklo simultaneously terminated its prior equity distribution agreement, which had allowed offerings of up to $1,500,000,000. Under that prior program, the company sold 15,774,224 shares of common stock for gross proceeds of approximately $1,499,867,429, and it incurred no termination penalties. Future sales, if any, will occur under the new agreement and related prospectus supplement filed under the existing Form S-3 shelf registration.
Oklo Inc. reported a larger quarterly loss as it accelerated investment and strengthened its balance sheet. For the three months ended March 31, 2026, the company posted a net loss of $33.1 million, compared with $9.8 million a year earlier, as research and development and general and administrative expenses rose to $27.0 million and $24.2 million, respectively.
Higher spending reflects headcount growth and sharply increased stock-based compensation, while interest and dividend income climbed to $21.3 million on a much larger cash and securities base. Oklo finished the quarter with $2.54 billion in cash, cash equivalents, and marketable debt securities and total assets of $2.70 billion, against modest liabilities of $64.9 million, leaving stockholders’ equity at $2.64 billion.
The company completed a 2025 at-the-market equity program in Q1 2026, issuing about 12.4 million shares for net proceeds of roughly $1.18 billion, and used $17.9 million of cash in operating activities and $32.8 million for capital expenditures. Management believes existing liquidity will fund operations for at least one year as Oklo advances its Aurora fast fission powerhouses, fuel recycling and fabrication projects, and radioisotope initiatives.
