Oklo Insiders Sell $83M as Shares Slide

NEW YORK, June 9 —

Oklo's top executives collectively sold $83.13 million in company shares over the 90 days ending June 9, with zero insider purchases to offset the flow. The pattern is deliberate: CEO Jacob DeWitte and COO Caroline Cochran executed sales on April 1, May 1, and June 1, with CFO Richard Craig Bealmear joining on at least two of those same dates. That calendar regularity, layered atop a dilutive equity offering in May and three straight quarters of earnings misses, raises a pointed question about what Oklo's founders believe the stock is worth at current prices.

The First of Every Month

Dewitte and Cochran, the company's co-founders, sold on the same three dates: April 1, May 1, and June 1. The CFO joined on April 1 and June 1. The simultaneity points toward pre-scheduled 10b5-1 plans, which provide an affirmative defense against insider trading claims by locking in sale parameters in advance. That reading is plausible. Still, $83 million in net sales is a bearish signal either way.

The individual transactions are substantial. Dewitte's largest single trade was 60,000 shares at $70.19 on May 1, generating $4.21 million in one tranche. Cochran matched that exactly: 60,000 shares at $70.19 on the same day, same proceeds. On June 1, Cochran sold another 60,000 shares at $68.29 for $4.10 million. CFO Richard Craig Bealmear was the most aggressive seller on June 1, unloading 73,081 shares across three separate transactions for combined proceeds of approximately $5.00 million. Chief Legal and Strategy Officer Goodwin William Carroll Murphy also sold in the period, disposing of 10,548 shares at $58.04 on May 20 for $612,206.

Across the entire executive suite over 90 days, the direction was uniform. Not one dollar flowed back into the stock.

The May Package

Two weeks after Dewitte and Cochran's May 1 sales, Oklo filed a 424B5 prospectus supplement with the SEC, indicating the company completed a registered securities offering on or around May 13, 2026. Equity offerings by pre-revenue companies dilute existing shareholders. Completing one while insiders were simultaneously selling compresses the equity from two directions at once: new shares increase supply, insider sales layer on additional pressure.

On the same day as the 424B5, Oklo filed an 8-K disclosing entry into a new material definitive agreement and the simultaneous termination of an existing one. The filing does not specify what was replaced or on what terms. In April, a separate 8-K flagged a change in directors or principal officers, with an event date of April 10. Leadership movement, agreement restructuring, and a capital raise concentrated in a single month is a lot of activity for a company the market is pricing on execution certainty.

Missing the Mark, Three Quarters Running

Oklo is pre-revenue, and the market prices it accordingly — on the trajectory to first commercial operation, not current income. Which makes the earnings miss pattern notable. The most recent reported quarter came in at -$0.27 per share against a -$0.16 consensus estimate. The prior quarter: -$0.20 versus -$0.12 expected. The quarter before that: -$0.18 versus -$0.11 estimated. Three consecutive misses, and the absolute gap between actual and estimate grew each time.

When a pre-revenue company consistently surprises to the downside on its cash burn, the implied question is whether the timeline and capital budget to first revenue are slipping. Trailing free cash flow stands at -$100 million on no reportable TTM revenue. If burn continues running hotter than analysts model, the path to commercial operation either takes longer than assumed or requires more capital to bridge. The May equity offering suggests the latter is already in motion.

What Changes the Thesis

This bearish read carries a caveat. Pre-scheduled 10b5-1 plans are a legitimate diversification tool, and the first-of-month cadence is consistent with automated execution rather than reactive selling on private information. Executives at high-growth companies with large equity compensation packages routinely liquidate on fixed schedules regardless of their private view on the stock. The dollar figures are large partly because Oklo traded in the $58 to $70 range over this period and executive stakes are correspondingly large.

The factors that would shift this picture: a signed power purchase agreement establishing a path to revenue, a Nuclear Regulatory Commission milestone compressing the timeline to commercial operation, or insider purchases appearing on Form 4 filings. None of those appear in the 90-day record. Until then, the insiders closest to Oklo's operations treated current prices as an exit, not an entry.
