Jacob Dewitte

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.

OKLO Co-Founder/CEO DeWitte sold 117,788 shares for $7,067,280 on 2026-03-13; stock down 9.1% in 30d, 28.5% in 90d.

DeWitte Jacob executed 2 separate sales totaling 117,788 shares at $60.00, reducing his holdings from 835,827 to 718,039 shares (-14.1%). The transaction occurred on 2026-03-13 at $60.00 per share while the current price stands at $59.69, placing the stock -65.7% from its 52-week high of $174.14 and off 28.5% over the past 90 days. Oklo remains unprofitable with a net income of $-29,722,000 in its most recent fiscal year. The timing of this sale by the founder/CEO warrants investor attention given the magnitude of the position reduction and the stock's sharp recent deterioration.

OKLO Co-Founder/CEO DeWitte Jacob sold 200,000 shares for $12.7M on 2026-03-02; post-sale holdings 1.31M shares, down 13.2%

DeWitte Jacob executed 12 separate sales totaling 200,000 shares for $12,658,097.15 at prices ranging from $60.44 to $64.33, achieving a blended average price of $63.29. The sale represents a 13.2% reduction in his holdings, leaving him with 1,310,000 shares post-transaction. This large liquidation by the Co-Founder and CEO occurs in a company that reported negative net income of $-29,722,000.00 over its most recent full fiscal year and is currently trading at $65.65, down 10.8% over the past 30 days and 41.2% over 90 days from the transaction date. His prior sell trades at OKLO in early February 2026 all generated negative 30-day returns (-11.0% to -16.0%), establishing a recent pattern of selling into declines at this specific ticker.

CEO DeWitte sells 200,000 shares (12.9% stake) for $15.0M at $74.96 avg; stock now -60.8% from 52-week high

DeWitte Jacob executed 12 separate sales totaling 200,000 shares (200.0K shares) for $14,992,025.35 ($15.0M) on 2026-02-02 at prices ranging from $73.81 to $78.20, reducing his holdings from 1,550,000 shares (1.55M shares) to 1,350,000 shares (1.35M shares)—a net reduction of -12.9% vs pre-transaction holdings. The timing is notable: the sales occurred at a blended average price of $74.96, but the current price is now $68.23, marking a -60.8% decline from the 52-week high of $174.14 and a 30-day decline of -23.6%. The company reported negative net income of $-29,722,000.00 ($-29.7M) over its most recent full fiscal year. While the CEO still retains substantial equity at 1.35M shares post-transaction, the large-scale disposition during a period of declining stock price and ongoing unprofitability warrants scrutiny regarding the company's near-term prospects.

CEO DeWitte Jacob sold 91,628 shares for $10,247,603.25 on 2026-01-09, reducing holdings by 6.2% amid stock down 44.2% from 52-week high.

DeWitte Jacob, as Co-Founder and CEO, executed 6 separate sales totaling 91,628 shares for $10,247,603.25 at a blended average price of $111.84 on 2026-01-09. This follows four prior sales at the same ticker just one day earlier (2026-01-08) and another on 2026-01-07, indicating a concentrated selling pattern within a three-day window. The stock currently trades at $97.09, down 44.2% from its 52-week high of $174.14, and the company posted a net loss of $29,722,000 over its most recent full fiscal year, raising questions about the timing and context of the CEO's significant equity liquidation. The reduction of 6.2% from pre-transaction holdings leaves Jacob with 1,390,000 shares, but the sustained, multi-day selling sequence amid recent stock weakness and ongoing unprofitability warrants scrutiny of management's confidence in near-term prospects.

Co-Founder/CEO DeWitte sold 328.4K shares for $32.5M across 20 transactions on Jan 7-8, reducing stake -18.9%

DeWitte Jacob, Co-Founder and CEO, executed 20 separate sales totaling 328,372 shares for $32,481,835.58 on January 7-8, 2026, at prices ranging from $93.79 to $100.06 with a blended average price of $98.92. The sale reduced his holdings from 1,737,445 to 1,409,073 shares, representing a -18.9% reduction in his position. This divestiture occurs in the context of Oklo Inc. posting a net income of $-29,722,000.00 over its most recent full fiscal year and a current stock price of $105.31, which is -39.5% from the 52-week high of $174.14. The magnitude of this multi-day liquidation, combined with the company's unprofitable fiscal performance and the stock's significant drawdown from its peak, warrants investor attention to the underlying drivers and timing context of this substantial CEO share reduction.

CEO DeWitte sold 200,000 shares for $18,058,200.00 at $90.29; stock down 45.1% from 52-week high, company posting $-29,722,000.00 net loss.

Co-Founder and CEO Jacob DeWitte executed 2 separate sales totaling 200,000 shares for $18,058,200.00 on 2026-01-05, reducing his holdings from 1,680,000 shares to 1,480,000 shares (-11.9% reduction). The sales occurred at $90.29 per share, substantially above the current price of $95.60 (note: current price exceeds transaction price, so the transaction was not executed during a local low). The broader context is material: Oklo Inc. reported a net loss of $-29,722,000.00 in its most recent full fiscal year, and the stock is trading -45.1% from its 52-week high of $174.14. Notably, DeWitte has engaged in frequent recent selling activity at OKLO (5 prior trades on 2025-12-22, outcomes not yet measurable), suggesting active liquidation of his position in a company trading well below its recent peak and operating at a significant loss.

CEO DeWitte sells 840,000 shares ($69.2M) in 12 tranches on 2025-12-22; holdings cut 34.7% to 1.58M shares

Co-Founder and CEO Jacob DeWitte executed 12 separate sales totaling 840,000 shares for $69,150,555.09 on 2025-12-22, reducing his stake from 2,420,000 to 1,580,000 shares—a 34.7% reduction in holdings. The sales occurred across a narrow price range ($80.84–$85.70), with a blended average of $82.32, near current market price of $81.88. Against a backdrop of the company's unprofitable fiscal year (net income of $-29,722,000.00), stock decline of 7.1% over 30 days and 37.6% over 90 days from the 52-week high of $174.14, and his prior OKLO sales in September 2025 that posted 30-day gains of 17.6–24.6%, this large liquidation of one-third of CEO holdings merits investor scrutiny. The scale ($69.2M raised), timing relative to recent sharp declines, and company fundamentals warrant close monitoring of whether additional insider activity or material developments follow.
