Top Small Modular Reactors Stocks: Our 5 Picks for 2026
These five SMR stocks span reactor developers, nuclear manufacturers, and fuel suppliers, with rankings based on overall investment quality rather than theme exposure alone.
Top Stocks · SMALL MODULAR REACTORSUpdated May 29, 2026
Small modular reactors are becoming investable because the power market increasingly needs firm, carbon-free electricity that can be built faster and with less upfront capital than traditional large nuclear plants. That matters in a market shaped by data-center demand, industrial electrification, grid reliability concerns, and rising electricity consumption tied to AI and reshoring. The story is no longer purely theoretical: the sector is shifting from long-dated research toward real project execution, manufacturing scale-up, and fuel-supply buildout.
Just as importantly, the opportunity extends well beyond reactor developers. The SMR value chain includes reactor designers, nuclear component manufacturers, and fuel suppliers, especially companies exposed to enrichment, fabrication, and other bottlenecks that advanced reactors will need to overcome before broad deployment. In practice, that means investors should separate near-term revenue businesses from pre-commercial developers. Some companies already generate meaningful sales and profits from nuclear components or fuel, while others are still funding design, licensing, and commercialization work.
For this list, we ranked five US-listed small modular reactor stocks and adjacent value-chain names by overall investment quality, not just thematic purity. That means balance-sheet posture, profitability, growth, earnings execution, and analyst sentiment all matter alongside direct exposure to SMR deployment. The countdown starts at No. 5 and works down to our top pick at No. 1.
Our screen focused on US-listed companies with market capitalizations above $500 million and meaningful exposure to the small modular reactor ecosystem, including reactor technology, nuclear components, and fuel supply. We then ranked the group by investment quality using our composite grade, profitability, growth trends, valuation context, and earnings consistency. Because this is a countdown, the names appear from No. 5 to No. 1, with the strongest overall quality profile in this theme saved for the end. The list is designed for monthly refreshes, so we emphasize durable business metrics over day-to-day stock moves.
What they do. The company supplies nuclear fuel components through its Low-Enriched Uranium segment and also provides manufacturing, engineering, and operations services through Technical Solutions. Centrus sells separative work units, enriched uranium products, uranium conversion, and related fuel inputs to utilities that operate nuclear power plants, giving it direct exposure to one of the most practical chokepoints in advanced nuclear deployment.
Why it fits. Fuel is one of the most important enabling layers in the SMR buildout, and Centrus is one of the clearest public-market ways to invest in that part of the chain. As advanced reactors move toward commercialization, enrichment and fuel fabrication capacity become strategic assets, especially for designs that require specialized supply rather than commodity uranium exposure alone.
Numbers that matter. Centrus generated $452.3 million in revenue, with a 13.4% profit margin and 25.7% gross margin, but operating margin was slightly negative at -0.26%. Revenue grew 4.9% year over year, while earnings growth fell 71.9% year over year, which helps explain the lower quality ranking. Valuation is demanding for a fuel supplier at 65.3 trailing earnings and 65.8 forward earnings, while return on equity was 12.25% and return on assets was just 0.79%.
Recent momentum. The company has beaten earnings estimates in 5 of the last 7 reported quarters, including a 288.9% upside surprise in May 2026 when it delivered $1.05 versus a $0.27 estimate. That said, results have been uneven, including a 43.6% miss in February 2026. Analyst sentiment is mixed rather than bullish, with 1 Buy and 2 Hold ratings and an average target of $278.64.
What they do. GE Vernova is a broad energy equipment and services company spanning Power, Wind, and Electrification. For SMR investors, the key point is that its Power segment designs, manufactures, and services nuclear technologies, while its broader grid and electrification footprint gives it exposure not only to generation but also to the transmission and orchestration infrastructure needed to integrate new firm power.
Why it fits. GE Vernova offers a more diversified way to play SMRs than a pure-play developer. It has direct nuclear exposure through its power technologies and also benefits from the same secular forces driving SMR interest: rising electricity demand, utility investment in reliability, and the need for firm low-carbon generation paired with modern grid equipment.
Numbers that matter. The company generated $39.37 billion in revenue and posted a 23.81% profit margin, 20.3% gross margin, and 5.46% operating margin. Revenue grew 16.3% year over year, while earnings growth surged 1,816.5% year over year, reflecting major operating improvement. Profitability metrics are strong, with return on equity of 75.71% and return on assets of 2.38%. Valuation is not cheap, but it is more grounded than many thematic names at 29.1 trailing earnings and 35.6 forward earnings.
Recent momentum. GE Vernova has beaten estimates in 4 of the last 7 quarters, including two outsized surprises in 2026: $17.44 versus a $2.00 estimate in April and $13.39 versus $3.22 in January. Analyst sentiment is constructive, with 8 Buy and 7 Hold ratings and an average target of $1215.86. The combination of scale, improving earnings, and direct nuclear relevance is why it ranks in the upper half of this list.
What they do. BWX Technologies manufactures nuclear components, reactors, fuel, pressure vessels, steam generators, fuel handling systems, and other precision equipment for government and commercial customers. Its business spans naval nuclear work, commercial nuclear plant components, fuel-related products, and specialized engineering services, making it one of the most established nuclear manufacturing platforms available to public investors.
Why it fits. SMR deployment will require more than reactor blueprints; it will require qualified manufacturers that can deliver nuclear-grade components, systems, and fuel-related assemblies at scale. BWXT sits squarely in that enabling layer. That makes it one of the cleaner execution-focused ways to invest in the theme, especially for investors who prefer existing revenue streams over pre-revenue reactor developers.
Numbers that matter.BWXT generated $3.38 billion in revenue with a 10.21% profit margin, 22.7% gross margin, and 10.38% operating margin. Revenue grew 26.1% year over year and earnings grew 20.7%, a strong mix for an industrial supplier tied to nuclear demand. Return on equity was 29.03% and return on assets was 5.96%, both solid. The tradeoff is valuation: shares change hands at 52.7 trailing earnings and 42.9 forward earnings.
Recent momentum. Few companies on this list have executed as consistently in quarterly reporting. BWXT has beaten estimates in 7 of the last 7 quarters, including 20.4% and 22.0% surprises in May and February 2026, respectively. Analysts remain favorable overall, with 3 Buy, 1 Hold, and 1 Sell rating, alongside an average target of $239.27.
