Oklo Drops 14.69% to 2025 Low as Momentum Reverses Post-Siemens Surge

The share price fell to its lowest level since September 2025 today, with an intraday decline of 14.69%. The selloff follows a sharp reversal in momentum for the pre-revenue nuclear technology developer, which had surged over 20% in November after a binding contract with Siemens Energy to advance its Aurora small modular reactor project. The partnership, aimed at accelerating hardware production for the Idaho National Laboratory deployment, had previously bolstered investor confidence, but recent volatility underscores the stock’s susceptibility to speculative trading and execution risks.

Oklo’s strategic collaboration with Siemens Energy represents a pivotal step in de-risking its Aurora project, which remains its first commercial-scale reactor initiative. Regulatory progress, including a U.S. Department of Energy approval for fuel fabrication, has streamlined pathways for recycled fuel production, aligning with the company’s vision to address nuclear waste challenges. However, the Aurora deployment timeline—targeting late 2027 to early 2028—remains contingent on navigating U.S. Nuclear Regulatory Commission licensing and supply chain hurdles for critical components. These milestones, while progress, highlight the extended timeframe for commercial realization.

The stock’s extreme volatility reflects its speculative nature, driven by news catalysts and positioning in the AI energy transition. Oklo’s focus on co-locating reactors with data centers taps into growing demand for low-carbon power, yet its pre-revenue status and $36.3 million operating loss in Q3 2025 underscore financial risks. Analysts remain divided, with price targets ranging from $14 to $175, as investors weigh long-term potential against near-term execution uncertainties. Broader industry tailwinds, including federal support for advanced nuclear, provide context, but Oklo’s path to profitability hinges on sustaining momentum amid regulatory and technical challenges.
