Oklo Inc. has secured approval from the U.S. Department of Energy's (DOE) Idaho Operations Office for the Preliminary Documented Safety Analysis (PDSA) regarding its Aurora powerhouse at Idaho National Laboratory (INL). The authorization was granted under DOE's Reactor Pilot Program (RPP), advancing the project through a framework designed to enable accelerated deployment of scalable generation capacity under federal oversight.

The PDSA represents a detailed review of the preliminary safety basis for Aurora-INL, encompassing the project's hazard analysis, accident analysis, safety controls, and design commitments. This approval establishes a foundation for future Aurora deployments and facilitates the progression of advanced reactors through safety review, construction, and commercial licensing phases.

Project Details and Fuel Source

Aurora-INL is set to be the first of Oklo's planned fast fission power plants. The project has been granted access to recovered fuel from the Experimental Breeder Reactor-II (EBR-II) following a competitive DOE process initiated in 2019. Oklo received a site-use permit at INL for the Aurora powerhouse in the same year.

Complementary Facilities and Licensing Strategy

The advancement of Aurora-INL occurs alongside Oklo's broader operations in Idaho, specifically the Aurora Fuel Fabrication Facility (A3F). This facility will fabricate the initial fuel assemblies for Aurora-INL using EBR-II fuel. The DOE's Idaho Operations Office previously approved A3F's PDSA in December 2025, marking it as the first facility approved under DOE's Fuel Line Pilot Program.

Through the RPP, Oklo aims to gain early deployment and operating experience with Aurora-INL. The company continues to pursue licensing from the U.S. Nuclear Regulatory Commission to support future commercial operations.

Oklo Inc. has acquired ARMEC, a precision manufacturing and engineering firm, for an undisclosed amount, in a move designed to strengthen its vertically integrated manufacturing capabilities for advanced reactor and fuel programs. The transaction closed on June 4, 2026, and is expected to streamline Oklo's design-to-manufacturing feedback while bolstering its deployment timeline.

ARMEC Acquisition Enhances Manufacturing Depth

ARMEC brings a workforce of roughly 40 nuclear-experienced engineers, machinists, welders, fabricators, and technical specialists, along with established relationships across the nuclear and industrial supply chain. The firm's core capabilities span precision machining, fabrication, prototyping, inspection, procurement support, and mechanical engineering.

ARMEC had already been working with Oklo prior to the acquisition, assisting in advancing nozzle manufacturing and helping transition from early test hardware to more structured production processes. This prior collaboration involved design refinement, inspection planning, quality controls, and supplier support.

DOE Surplus Plutonium Program Selection

Ahead of the ARMEC announcement, Oklo disclosed it had been selected by the U.S. Department of Energy for advanced negotiations under the Surplus Plutonium Utilization Program. Oklo stated the selection supports its broader fuel strategy by creating another potential pathway to source fuel while domestic enrichment and fuel infrastructure continue scaling.

Analyst Ratings and Earnings Outlook

Oklo carries a Buy consensus rating among analysts, with an average price target of $100.64. Recent analyst actions reflect a range of views on the stock's near-term trajectory.

Oklo is slated to provide its next financial update on August 10, 2026 (estimated). Key estimates for the upcoming report are as follows:

• EPS Estimate: Loss of 17 cents (up from a loss of 18 cents)
• Revenue Estimate: $91,420 (up from $0.00)

Technical Levels and ETF Exposure

The stock was trading at $60.25, approximately 11.8% below its 20-day simple moving average (SMA) of $66.60. The moving average convergence divergence (MACD) was below its signal line, indicating fading momentum.

• Key Resistance: $66.00 — a nearby level tied to the 20-day SMA where rebounds can stall
• Key Support: $54.00 — a nearby level aligning with the 52-week low zone where buyers previously stepped in

Oklo carries a 5.87% weight in the Global X Uranium ETF. Given this significant weighting, notable inflows or outflows in the ETF may result in automatic buying or selling of the stock. Oklo shares were up 2.58% at $59.59 at the time of publication on Monday.
