Oklo Acquires ARMEC to Expand Vertically Integrated Manufacturing Capabilities for Advanced Reactor and Fuel-Manufacturing Programs
- ARMEC is a precision manufacturing and mechanical engineering company specializing in high-precision machining and prototyping for the nuclear industry.
- The acquisition strengthens integration across engineering, manufacturing, and deployment.
- During its most recent fiscal year, ARMEC generated positive free cash flow.
Oklo Inc. (NYSE:OKLO) ("Oklo"), an advanced nuclear technology company, today announced that it has acquired ARMEC, a precision manufacturing and engineering firm based in Oak Ridge, Tennessee. The acquisition expands Oklo's in-house capabilities for its advanced reactor and fuel-manufacturing programs, supports faster design-to-manufacturing feedback, and provides additional control over key elements of Oklo's deployment timeline.

ARMEC brings more than two decades of operating experience; a team of approximately 40 engineers, fabricators, machinists, welders, and technical personnel with extensive nuclear experience; and established relationships across the nuclear and industrial manufacturing supply chain. Its capabilities include high-precision machining, prototyping, fabrication, inspection, procurement support, and mechanical engineering.
The acquisition, closed on June 4, 2026, reflects Oklo's broader strategy of integrating critical execution capabilities closer to its reactor, fuel fabrication, and recycling programs as it advances from design into deployment. ARMEC has already supported Oklo's engineering teams in maturing nozzle manufacturing from early test-fit hardware into more controlled manufacturing workflows, including drawing development, inspection planning, quality assurance procedures, and supplier process troubleshooting.
"Advanced nuclear deployment requires manufacturing depth," said Oklo CEO and co-founder Jacob DeWitte. "ARMEC strengthens Oklo's capabilities by expanding practical engineering, fabrication, inspection, and procurement. We plan to continue to invest in the local workforce and community to ensure ARMEC's success and given Oak Ridge's importance to us and the nuclear industry."
"We have built ARMEC around practical execution, technical quality, and close customer collaboration," said ARMEC President Travis Reagan. "Joining Oklo gives our team the opportunity to apply that experience to one of the most important challenges in energy: building the manufacturing foundation needed to support advanced nuclear deployment. We are excited to bring our capabilities, supplier relationships, and Oak Ridge–based team into Oklo as we continue supporting customers and expanding the role our work can play in the nuclear supply chain."
Founded in 2002, ARMEC has supported customers across nuclear, R&D, energy, and defense markets, including high-precision manufacturing work for major advanced energy programs such as U.S. ITER components for the international fusion project in France. ARMEC's leadership will continue to support the business following the acquisition to preserve customer continuity, technical know-how, and supplier relationships.
Oklo expects the acquisition to provide benefits across three primary areas:
- Talent: ARMEC's team brings engineering, prototyping, fabrication, welding, machining, and manufacturing experience to support Oklo's reactor and fuel-manufacturing programs.
- Capabilities: ARMEC's manufacturing, testing, inspection, procurement, and prototyping capabilities can support components and workflows that are important to Oklo's commercialization timeline.
- Strategic relationships: ARMEC's established relationships with key customers and suppliers help improve Oklo's visibility into supply-chain constraints and create opportunities for stronger coordination across the industry to eliminate those constraints.
During its most recent fiscal year, ARMEC was a free cash flowing business, reflecting the strength of its specialized capabilities and business model.
About Oklo Inc.: Oklo Inc. is developing fast fission power plants to deliver clean, reliable, affordable energy at global scale; establishing a domestic supply chain for critical isotopes; and advancing nuclear fuel recycling to convert used nuclear fuel into clean energy.
