Specifically, he sold 60,000 shares held directly and 40,000 shares via the Jacob DeWitte GRAT. His spouse, Caroline Cochran, through her individual holdings and related GRATs and family trusts, sold an additional approximately 100,000 shares.

Following these transactions, DeWitte and his spouse still beneficially own a substantial number of Oklo shares via several trusts. While insider and large-shareholder sales near higher price ranges can be perceived as a modestly negative signal, these trades were executed pursuant to a pre-established Rule 10b5-1 plan and may primarily reflect liquidity or portfolio considerations. Investors should evaluate this activity in the context of Oklo’s fundamentals and outlook.
