Oklo Inc. insider Richard Craig Bealmear reported a July 1, 2026 ownership change involving the company’s Class A common stock. The filing reflects a same-day option exercise and stock sale: Bealmear exercised options for 16,321 shares at an exercise price of $3.18 per share, and sold Class A common stock at $52.63 per share. Based on the reported figures, the option exercise cost was about $51,901, while the sale generated gross proceeds of about $858,969 before taxes, fees, and any other costs. The sale was disclosed as being made under a Rule 10b5-1 trading plan that Bealmear adopted on September 22, 2025. Such plans allow insiders to schedule trades in advance under preset conditions, which can help avoid concerns that trades were made on the basis of later-acquired material nonpublic information. After the reported common-stock transaction, Bealmear beneficially owned 460,878 shares of Oklo Class A common stock.
