OKLO CEO Jacob Dewitte sells 200,000 shares for $10,585,600.00 as stock down 73.0% from 52-week high

Jacob Dewitte (Co-Founder, CEO) executed 4 separate sales totaling 200,000 shares (200.0K shares) for $10,585,600.00 ($10.6M) on 2026-07-01, reducing his holding by 26.0% vs pre-transaction holdings from 769,479 shares to 569,479 shares. The sales occurred at an average price of $52.93, compared to the current price of $52.37, near the 52-week low after a -73.0% decline from the $193.84 52-week high and a -28.7% drop over 30 days. His prior sales at OKLO over the same period (5 recent transactions on 2026-06-01) were followed by sharp 30-day declines ranging from -19.3% to -25.6%. The company reported net income of $-33,065,000.00 ($-33.1M) in its most recent full fiscal year, indicating ongoing unprofitability. This transaction merits scrutiny given the magnitude of the sale by the CEO during a period of significant stock depreciation and operational losses.

CEO Jacob Dewitte sells 200,000 shares (200.0K) for $13.7M; 10b5-1 plan; stock up 11.9% in 90 days post-sale.

Jacob Dewitte, Co-Founder and CEO, executed 8 separate sales totaling 200,000 shares for $13,657,879.60 on 2026-06-01, reducing his stake by 24.7%. This transaction was executed under a pre-arranged 10b5-1 trading plan adopted on 2025-03-31, meaning it was scheduled rather than discretionary. Post-transaction, the stock has appreciated 11.9% over the past 90 days and currently trades at $73.47 versus the blended average sale price of $68.29. Notably, his five prior OKLO sales in May 2026 all generated negative 30-day and 90-day returns (ranging from -3.1% to -5.7%), whereas his broader cross-ticker track record shows average 90-day returns of +16.9% after prior sells; this June sale has benefited from subsequent price appreciation, a different outcome than his recent OKLO pattern. The company reported net income of -$33,065,000.00 for its most recent full fiscal year, placing the transaction within an unprofitable operational context.

Oklo Co-Founder and CEO sells 200K shares in six separate transactions, largest insider sale in months from company leadership.

Dewitte Jacob, Oklo's Co-Founder and CEO, executed a significant liquidation of 200,000 shares over a single trading day, representing approximately 27% of his holdings. This is the 113th open-market sale he has made in the past 36 months—a pattern of consistent selling with no open-market purchases during this period. The timing is notable: while Oklo trades well below its 52-week high and the company remains unprofitable, Jacob is selling into strength from a recent surge in share price. His prior five sales at Oklo all resulted in the stock rising afterward, indicating uniformly poor timing on his previous exits—he has never captured a well-timed sale at this company. The size and frequency of Jacob's selling, combined with his track record of exiting before subsequent gains, suggests ongoing portfolio reduction from the company's leadership rather than conviction about value at current levels.

CEO DeWitte sells 200,000 shares (22.5% of holdings) for $10.1M across 10 transactions on 2026-04-01; stock -72.4% from 52-week high, -24.0% in 30 days.

Co-Founder and CEO Jacob DeWitte executed 10 separate sales totaling 200,000 shares for $10,069,852.10 on 2026-04-01, reducing his holdings from 889.5K to 689.5K shares (-22.5%). The blended average transaction price was $50.35, but the current price stands at $48.13, representing a -72.4% decline from the 52-week high of $174.14 and a -24.0% 30-day drop. His prior sales at OKLO exhibit poor timing outcomes: trades from 2026-03-02 show 30-day returns of -21.8%, -25.0%, and -25.3%, with stock continuing downward after each sale. The company is unprofitable with a net income of $-29,722,000.00 over its most recent fiscal year, and DeWitte's cross-ticker track record shows 20 prior sells averaging -20.1% 30-day return. The sheer volume—22.5% of holdings divested in a single day across 10 tranches at incrementally rising prices from $48.41 to $51.20—indicates significant capital reallocation from the CEO amid deteriorating fundamentals and stock performance.

The blended average price across all transactions was $63.29 per share, with individual transaction prices ranging from $60.44 to $64.33. Since the sales followed a predetermined plan, no timing inference can be drawn from their execution on this date. Post-transaction, DeWitte retains 1.31M shares, maintaining a substantial ongoing ownership position in the company.

Critically, this filing is part of a pre-arranged 10b5-1 trading plan adopted on 2025-03-31, indicating these sales were scheduled, not discretionary trading. As a routine-execution 10b5-1 transaction, this event reflects administrative portfolio management rather than real-time insider conviction signals about the company's near-term direction.

DeWitte retains 1,480,000 shares post-transaction, maintaining substantial ongoing ownership. The scheduled nature of the trades removes timing interpretation from consideration, and the sale reflects execution of a plan formulated in advance rather than a response to current market conditions.

Co-Founder & CEO DeWitte Jacob sells 840,000 shares for $69,150,555.09 via scheduled 10b5-1 plan

DeWitte Jacob executed 12 separate sales totaling 840,000 shares (840.0K shares) for $69,150,555.09 ($69.2M) across a range of prices from $80.84 to $85.70 on 2025-12-22. This sale reduces his holdings from 2,420,000 shares (2.42M shares) to 1,580,000 shares (1.58M shares), a reduction of -34.7% of pre-transaction holdings. The transaction was part of a pre-arranged 10b5-1 trading plan adopted on 2025-03-31, making it scheduled rather than discretionary. The magnitude of the divestiture—involving the Co-Founder and CEO disposing of over one-third of his shareholding in a single day—represents a material shift in insider ownership concentration and warrants investor scrutiny of the underlying drivers and company fundamentals.
