Industry Overview - Nuclear energy is regaining favor globally due to its efficiency, reliability, and zero emissions, with a focus on recommissioning old plants and developing new technologies like small modular reactors (SMRs) [1] - The U.S. Department of Energy estimates a need for 200 gigawatts (GW) of new nuclear capacity to meet future power demands and net-zero emission goals, planning to add 35 GW by 2035 and 15 GW per year through 2040 [6] Company Profiles Oklo - Founded in 2013, Oklo is developing advanced fission power plants using metal-fueled fast-reactor technology, with its core product being the Aurora powerhouse [7] - The Aurora powerhouses are designed to produce electricity in compact sizes, initially targeting 15 MWe and 75 MWe, with potential expansion to 100 MWe and higher [7] - Oklo aims to have its first Aurora powerhouse operational by late 2027 or early 2028, but has not yet built any operational units or secured binding customer agreements [9] Centrus Energy - Centrus Energy, operational since 1998 and restructured in 2014, provides nuclear fuel components and enrichment services, primarily generating revenue from selling low-enriched uranium (LEU) [10] - The company currently relies on outside sources for LEU, including an agreement with a Russian entity, but faces a need to replace about 25% of enriched uranium imports from Russia due to an expected import ban by 2028 [11] - Centrus aims to produce LEU and high-assay, low-enriched uranium (HALEU) in-house using advanced centrifuge technology, with plans to expand its enrichment capacity contingent on funding and customer commitments [13] Investment Considerations - Both Oklo and Centrus Energy are positioned to benefit from favorable tailwinds in the nuclear energy sector, but Oklo lacks a commercial product and will take two to three years before its reactor comes online [15] - Centrus Energy is established as a provider of key components used in nuclear plants, generating revenue currently, which gives it an edge in investment considerations [15]

Core Insights - The global clean energy sector is evolving, with nuclear energy stocks like Oklo Inc. (OKLO) and NANO Nuclear Energy Inc. (NNE) gaining attention due to rising government support and investment in small modular and advanced nuclear technologies [1][2] Group 1: Company Achievements - Oklo's subsidiary, Atomic Alchemy, began site characterization work for a commercial radioisotope production facility in Idaho in June 2025 [3] - Oklo received a Notice of Intent to Award for deploying its Aurora powerhouse at Alaska's Eielson Air Force Base, which would allow it to design, build, and operate the plant [4] - The U.S. Nuclear Regulatory Commission started reviewing Oklo's Licensed Operator Topical Report, indicating progress towards obtaining a license for its Aurora powerhouses [5] - NANO Nuclear signed a Memorandum of Understanding with the Namibia Industrial Development Agency to explore building a domestic nuclear fuel supply chain in Namibia [8] - NANO Nuclear filed six new utility patent applications for its ZEUS microreactor, showcasing its commitment to innovation in compact nuclear technologies [9] Group 2: Financial Stability - Oklo ended Q1 2025 with $201 million in cash and cash equivalents, indicating a solid financial footing to support its Aurora powerhouse development [6] - NANO Nuclear ended the fiscal second quarter of 2025 with $119 million in cash and cash equivalents, also showing a strong liquidity position [10][11] Group 3: Challenges - Oklo is in the pre-revenue stage, with its first Aurora powerhouse not expected to be operational until 2027, leading to limited income opportunities in the short term [7] - NANO Nuclear is also in the pre-revenue stage, focusing on R&D for its microreactors, which presents limited income opportunities and long regulatory timelines [12] Group 4: Earnings Estimates - The Zacks Consensus Estimate for Oklo's 2025 EPS is a loss of 46 cents per share, an improvement from a loss of 74 cents per share the previous year [13] - The Zacks Consensus Estimate for NNE's fiscal 2025 EPS is a loss of $1.05 per share, a deterioration from a loss of 39 cents per share the previous year [14] Group 5: Stock Performance and Valuation - Oklo shares increased by 549.2% year over year, significantly outperforming NNE's 119.9% stock price gain [10][18] - Oklo's trailing 12-month Price/Book (P/B TTM) ratio is 28.72X, compared to NNE's 10.02X, indicating that NNE may offer a more attractive valuation [19] Group 6: Conclusion - Oklo has a stronger cash position and recent regulatory progress, while NANO Nuclear is at an earlier stage with a smaller capital base [22] - Oklo shows stronger stock momentum and improving EPS trends, while NNE appeals to value-oriented investors [23]
