Oklo Inc.'s stock plummeted 6.72% in pre-market trading, extending a recent selloff following the company's latest earnings report.

The decline is primarily driven by the company's disappointing Q1 fiscal 2026 results, which showed a net loss that widened sharply to $33.1 million from $17.9 million a year earlier, exceeding analyst estimates. As a pre-revenue advanced nuclear energy company developing its Aurora small modular reactor, the widening losses have intensified investor concerns over cash burn rates and the timeline for commercialization.
