Oklo rises for the week after Centrus fuel agreement draws attention to nuclear supply concerns

Oklo Inc. will post its first-quarter numbers after Tuesday’s close, just days after announcing a regulatory green light for major design elements tied to its Aurora project in Idaho. Investors will be watching how the nuclear developer is managing its cash and progress on approvals. Co-founder and CEO Jacob DeWitte, along with CFO Craig Bealmear, are scheduled to lead a conference call at 5 p.m. ET.

Late Friday, Oklo Inc. executive Caroline Cochran filed a Form 144, signaling plans to unload as many as 300,000 Class A shares in the nuclear developer. The filing put the target sale’s value at $21.75 million.

Regulatory filings released Friday reveal Oklo insiders unloaded shares last week, but the numbers don’t quite match up with the $21 million figure circulating in some market summaries. A closer look at the paperwork puts the total closer to $10.9 million. Co-founders Jacob DeWitte and Caroline Cochran disclosed April 1 stock sales executed through pre-set Rule 10b5-1 trading plans. CFO Richard Bealmear, on the other hand, posted a separate sale following an option exercise.

Oklo on Tuesday posted a larger loss for 2025, underscoring the hefty outlays required to get a pioneer nuclear venture off the ground before major revenue kicks in. Still, with new U.S. approvals advancing its reactor and isotope initiatives, investors shrugged off the red ink and shares ended up a bit.
