OKLO--
Klein sold 40,000 shares at an average price of $133.40 apiece and an additional 10,000 shares for $135.20 each. The day of Klein’s stock sale, Oklo held a groundbreaking ceremony for its first power plant at Idaho National Laboratory. Oklo closed at a record on September 22 and again on September 23, before shares slumped as investors questioned both companies’ fundamentals. From Oklo’s record close of $142.65 through the end of Friday’s session, shares fell 22%. Despite the decline, the stock is still up more than 400% this year [1].
Oklo noted in its most recent quarterly filing with the SEC that it "continues to incur significant operating losses." The company’s ambitious targets have also faced scrutiny. Oklo company says it remains on track to deploy its first Aurora powerhouse by 2027 or 2028, despite currently lacking an operating license [1].
Oklo Inc. has been attracting attention, including at the federal level. The company was selected for a pilot program under the Department of Energy, which aims to have at least three test reactors up and running at national laboratories across the country by July 2026 [1].
Oklo and Sweden's Blykalla have announced a strategic transatlantic partnership to enhance advanced nuclear technology and its commercialization. The collaboration focuses on tech sharing, supply chain coordination, and regulatory knowledge exchange. This partnership aims to accelerate the commercialization of advanced nuclear reactors, a key component in the clean energy transition [2].
The partnership includes Oklo co-leading Blykalla's next investment round with a $5 million commitment, which reinforces the transatlantic collaboration to fast-track advanced nuclear commercialization. Oklo may also supply select components for Blykalla's direct use, enhancing a vertically integrated, cross-border supply chain [2].
Oklo Director Michael Stuart Klein sold 50,000 shares of the nuclear start-up for $6.7 million in two transactions on September 22. The sales occurred when shares were near all-time highs, before they plummeted. Klein is a 10% owner and independent director of the company.
