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.

OKLO reported a proposed sale of 16,321 Class A shares via a stock option exercise to be effected on 07/01/2026 for cash through Fidelity Brokerage Services LLC. The filing also lists recent dispositions by Richard C. Bealmear, including 16,342 shares on 04/01/2026 for $834,749.36 and 73,081 shares on 06/01/2026 for $5,000,236.58.
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.
Kan Derek T. reported acquisition or exercise transactions in this Form 4 filing.
Oklo Inc. director Derek T. Kan received a grant of 3,213 Restricted Stock Units (RSUs), each representing one share of Class A Common Stock. These RSUs vest in full on June 3, 2027, meaning the shares are delivered only if the vesting conditions are met.
Following this award, Kan holds 7,912 RSUs in total. This is a compensation-related equity grant, not an open‑market stock purchase or sale, and therefore does not reflect a trading decision based on Oklo’s share price.
