Portfolio Holdings Overview

Nuclear Stock Profiles

LEU — Centrus Energy Corp.

Centrus Energy (ticker: LEU) is the only US-licensed producer of High-Assay Low-Enriched Uranium (HALEU), the advanced fuel required by most next-generation reactor designs including TerraPower's Natrium SMR and many other advanced concepts. The company also enriches conventional low-enriched uranium for US commercial nuclear plants. As the nuclear renaissance accelerates demand for enriched uranium, Centrus is uniquely positioned as a domestic US supplier of both conventional and advanced nuclear fuel. Centrus operates the American Centrifuge Plant in Piketon, Ohio — the only commercial-scale uranium enrichment facility in the United States.

OKLO — Oklo Inc.

Oklo Inc. (ticker: OKLO) is developing compact, sodium fast-spectrum microreactors capable of running on conventional low-enriched uranium or recycled nuclear spent fuel. The company's flagship Aurora reactor produces 15 MW of electricity with an extremely small footprint — roughly the size of a small warehouse. Backed by Sam Altman (OpenAI CEO), Oklo has positioned itself as a nuclear power supplier to AI data centers, defense installations, and remote industrial operations. Oklo's unique fast reactor design also enables "nuclear recycling" — using spent nuclear fuel from conventional reactors, potentially reducing the long-lived waste problem while generating additional electricity. Oklo went public via SPAC merger in 2024.

BWXT — BWX Technologies Inc.

BWX Technologies (ticker: BWXT) is the preeminent manufacturer of nuclear reactor components in the United States, supplying both the commercial power industry and the US Navy's nuclear propulsion program. BWXT manufactures reactor pressure vessels, steam generators, reactor heads, and precision nuclear fuel assemblies. The company's long-term contracts with the US Navy provide stable revenue regardless of commercial market cycles, while its commercial nuclear business benefits from both existing plant maintenance/component replacement and new reactor builds. BWXT is also developing its own BANR (BWX Advanced Nuclear Reactor) microreactor design for remote communities and military bases.

CCJ — Cameco Corporation

Cameco (ticker: CCJ) is one of the world's largest publicly traded uranium producers, operating world-class mines including Cigar Lake and McArthur River in Saskatchewan, Canada — among the highest-grade uranium deposits on Earth. As uranium demand surges on the back of the global nuclear renaissance, Cameco is aggressively restarting curtailed production capacity and extending mine life at existing assets. The company also holds a 49% stake in Global Laser Enrichment, a potential future enrichment technology. Cameco sells uranium through long-term contracts with utilities worldwide, providing revenue visibility that insulates it from spot market volatility while still allowing participation in price upside.

SMR — NuScale Power Corp.

NuScale Power (ticker: SMR) achieved a historic milestone in 2022 as the first company to receive NRC design certification for a light water Small Modular Reactor in the United States. NuScale's VOYGR plant uses 77 MW modules that can be deployed in groups of 4, 6, or 12, scaling from 308 MW to 924 MW total output. The reactor uses passive natural circulation cooling — no pumps required — and is designed to shut down safely without any operator intervention or external power. NuScale is actively marketing the VOYGR to utilities in North America, Europe, and Asia. The company is developing a next-generation 77 MWe module from the original 60 MWe design, improving economics per unit of output.

NXE — NexGen Energy Ltd.

NexGen Energy (ticker: NXE) controls the Arrow uranium deposit in the Athabasca Basin of Saskatchewan — one of the largest high-grade uranium discoveries in history. Arrow contains over 256 million pounds of uranium in the indicated resource category at exceptionally high grades, making it potentially one of the most economic uranium mines ever developed once it enters production. NexGen has received regulatory approval from the Canadian Nuclear Safety Commission and is advancing toward a final investment decision. Production startup is targeted for the late 2020s, which would make NexGen a major global uranium supplier precisely when demand from new nuclear build is expected to peak.

Uranium Market Fundamentals

The uranium spot market has been in structural deficit for several years as mine production has failed to keep pace with reactor fuel requirements. Many uranium mines were shut down or placed on care-and-maintenance during the prolonged post-Fukushima price collapse (2011–2020). With uranium prices now well above the incentive price needed to restart suspended production, but with long lead times for mine development, the market is expected to remain tight through the late 2020s.

Nuclear Sector Investment Thesis

The nuclear energy investment thesis rests on three converging forces that are reinforcing each other simultaneously:

1. AI Data Center Power Demand: The exponential growth of artificial intelligence is driving unprecedented electricity demand that grid-scale renewable energy alone cannot reliably satisfy. Tech companies are signing 20-year nuclear power purchase agreements to secure guaranteed clean power for always-on AI infrastructure — providing bankable revenue streams for nuclear operators and developers.

2. Energy Security and Decarbonization: Geopolitical instability in natural gas markets (Europe's experience with Russian gas) and government commitments to net-zero emissions are driving a global reassessment of nuclear power. Over 20 countries have pledged to triple nuclear capacity by 2050 at COP28. New government loan guarantees and production tax credits under the US Inflation Reduction Act provide significant financial support for nuclear projects.

3. Uranium Supply Deficit: A decade of underinvestment in uranium mining has created a structural supply deficit. Even at current elevated prices, it takes 5–10 years to bring a new uranium mine into production. The deficit is expected to widen through the late 2020s, supporting sustained high uranium prices that benefit miners like CCJ and NXE.
