Oklo (NYSE: OKLO) plans to release its financial results and business updates for the second quarter ended June 30, 2026, before the market opens on Friday, August 7, 2026. Management will host a webcast and conference call at 8:30 a.m. Eastern Time to discuss the quarter.
Oklo (NYSE: OKLO) received U.S. Department of Energy (DOE) startup authorization for its Groves Isotope Test Reactor at the Groves site in Lockhart, Texas. The authorization, granted under DOE’s Reactor Pilot Program, completes DOE’s process and enables fuel loading, startup testing, and initial reactor operations.
The low-power, privately financed Groves reactor was taken from groundbreaking to startup authorization in just over 10 months and is designed to demonstrate reactor design, construction, and operations to support Oklo’s plans for commercial-scale domestic isotope production. Oklo built the facility on private land, established its operating organization, qualified personnel, implemented in-house safety and operating programs, and procured fuel and major equipment from commercial suppliers, creating a repeatable, commercially oriented deployment model for future projects.
Oklo (NYSE: OKLO) announced U.S. Department of Energy approval of the Documented Safety Analysis (DSA) for the Groves Isotope Test Reactor in Texas under the DOE Reactor Pilot Program.
With both PDSA and DSA approved, Groves enters DOE’s final pre-startup phase, including readiness review and startup approval. Following startup approval, the reactor may load fuel, conduct startup testing, and move toward first criticality, which Oklo is targeting for July 2026. Groves is described as the first advanced reactor DSA approved for a facility on privately owned land using commercially sourced fuel and equipment. The project is intended to support Oklo’s isotope business and strengthen domestic supplies of critical isotopes for cancer diagnosis and treatment, manufacturing, research, space, and national security.
Oklo (NYSE: OKLO) acquired Creative Engineers (CEI), a chemical process engineering firm specializing in sodium and alkali-metal systems, to support its sodium-cooled Aurora powerhouse reactor.
The deal adds CEI’s liquid-metal design, fabrication, testing, safety training capabilities, around 20 specialists, and a business that has generated positive free cash flow for over five years.
Eagle Nuclear Energy (NASDAQ: NUCL) is pursuing an integrated strategy across domestic uranium and small modular reactors (SMRs). It controls the Aurora Uranium Project in Oregon, described as the largest conventional measured-and-indicated U.S. uranium resource, and has engaged Tensor Medium to support AI-based SMR simulation and optimization.
Aurora hosts 32.75 million pounds indicated and 4.98 million pounds inferred uranium resources. Eagle targets a Pre-Feasibility Study in the second half of 2027 and plans a 47-hole, ~27,000-foot drill program starting July 2026, while advancing an early-stage SMR program.
Centrus Energy (NYSE: LEU) and Oklo (NYSE: OKLO) signed a non-binding Letter of Intent for Centrus to supply enough domestic HALEU from its American Centrifuge Plant to power up to five Aurora powerhouses for multiple years, with deliveries starting in 2029.
The fuel would support Oklo's planned 1.2 GW clean energy campus in southern Ohio and may include prepayments. Centrus plans to leverage billions in private capital plus a $900 million U.S. Department of Energy HALEU task order, while both companies project thousands of construction and operating jobs in Ohio.
Oklo (NYSE: OKLO) and Standard Nuclear formed a strategic alliance under an MOU to explore nuclear fuel recycling and advanced fuel manufacturing. The collaboration targets recycled material offtake from Oklo’s planned Oak Ridge fuel recycling facility and the responsible use of U.S. surplus plutonium for advanced reactor fuel.
The alliance supports domestic nuclear fuel supply chains, potential TRISO fuel feedstock, and recovered isotopes for terrestrial, space, defense, industrial, healthcare, and research applications, aligning with U.S. policies to expand nuclear energy and critical fuel supplies.
Oklo (NYSE: OKLO) announced that the U.S. Department of Energy’s Idaho Operations Office approved the Preliminary Documented Safety Analysis (PDSA) for the Aurora powerhouse at Idaho National Laboratory under the Reactor Pilot Program.
The approval advances Aurora-INL’s safety-reviewed development, supports use of recovered EBR-II fuel, and builds experience ahead of future commercial licensing.
Oklo (NYSE: OKLO) acquired ARMEC, a precision manufacturing and mechanical engineering company in Oak Ridge, Tennessee, on June 4, 2026. ARMEC adds around 40 nuclear-experienced staff and vertically integrated machining, prototyping, fabrication, and inspection capabilities to support Oklo’s advanced reactor, fuel-manufacturing, and deployment programs.
According to Oklo, ARMEC generated positive free cash flow in its most recent fiscal year and brings established customer and supplier relationships across nuclear, energy, R&D, and defense markets, supporting Oklo’s commercialization timeline and supply-chain coordination.
Oklo (NYSE: OKLO) was selected by the U.S. Department of Energy for advanced negotiations under the Surplus Plutonium Utilization Program, which aims to convert designated surplus plutonium into fuel for advanced reactors under strict U.S. security and safeguards requirements.
Oklo, partnering with European reactor developer newcleo, plans for Oklo to lead utilization of surplus plutonium while newcleo contributes fuel expertise and potential project capital, including an investment of up to $2 billion for U.S. fuel fabrication infrastructure, subject to definitive agreements and approvals. In February 2026, newcleo began pre-application engagement with the U.S. Nuclear Regulatory Commission for an advanced fuel fabrication facility and a lead-cooled fast reactor design to support future U.S. deployment.
