Nuclear energy stocks remain one of the market’s most closely watched power themes because the investment case now reaches far beyond decarbonization alone. The backdrop is a mix of clean baseload demand, AI and data-center electricity needs, energy security concerns, and a policy push to accelerate new capacity. That combination is pulling nuclear into the broader infrastructure conversation, especially as utilities and hyperscalers look for reliable 24/7 generation that can complement intermittent wind and solar.
The opportunity set is also wider than many investors assume. Nuclear exposure can come through uranium miners, fuel-cycle specialists, reactor technology and services providers, large-cap power producers with nuclear fleets, and small modular reactor developers. Structurally, the bull case rests on several layers at once: stronger uranium demand, tighter fuel-cycle economics, life extensions and restarts for existing reactors, and a longer-dated buildout that could benefit engineering and equipment suppliers. Reuters’ January 9, 2026 report that Meta signed 20-year agreements tied to three Vistra nuclear plants and projects with two SMR companies only reinforced the idea that Big Tech is becoming a real demand driver.
For investors, that breadth makes stock selection especially important. Some names offer direct leverage to uranium pricing, some provide steadier utility-style cash flows, and some are essentially venture-stage bets on future reactor deployment. This list ranks nine US-listed nuclear energy stocks in countdown order from No. 9 to No. 1 using investment quality as the main criterion, so the strongest overall pick appears at the end.
To build this list, we screened for US-listed nuclear-related stocks with market capitalizations above $500 million and then ranked them primarily on investment quality rather than pure upside. Our review emphasized composite quality grades, profitability, growth, earnings consistency, valuation context, and analyst sentiment, while also considering how directly each company is tied to the nuclear theme. Because this is a countdown, the names start with the weaker overall quality setups and work toward the best pick at No. 1. The list is designed for monthly refreshes, so the focus is on durable business and financial metrics rather than short-lived price action.
9. CCJ — Cameco Corp
Market cap: $45.8B · Quality grade: B+ · Analyst consensus: Neutral (avg target $137.90)
What they do. The company supplies uranium for electricity generation and operates across Uranium, Fuel Services, and Westinghouse. That means Cameco is not just a miner: it also refines, converts, and fabricates fuel products, while Westinghouse adds reactor technology, outage support, engineering, instrumentation and controls, and plant modification services for utilities and government customers.
Why it fits. Cameco is one of the broadest pure-play nuclear supply-chain names in the market because it spans uranium production, fuel-cycle services, and reactor-related support. In a theme driven by higher uranium demand and renewed interest in extending and upgrading reactor fleets, that combination gives it exposure to both the commodity side and the installed-base service side of nuclear.
Numbers that matter. Cameco generated $3.54 billion in revenue with an 18.39% profit margin and $893.9 million in EBITDA. Profitability is solid, with a 36.8% gross margin, 18.19% operating margin, 18.39% net margin, 9.6% ROE, and 3.57% ROA. Growth has been respectable but not explosive on the top line, with revenue up 7.1% year over year, while earnings growth ran 87.5%. The catch is valuation: trailing P/E is about 97.35 and forward P/E about 94.34, which helps explain why a fundamentally strong operator still lands lower in a quality-ranked list.
Recent momentum. Earnings have improved lately even though the longer record is mixed. Cameco beat estimates in 4 of the last 8 quarters, but the two most recent reports were strong: EPS of $0.47 versus $0.2905 on May 1, 2026, a 61.8% surprise, and $0.50 versus $0.32 on February 13, 2026, a 56.3% surprise. Analysts remain constructive overall, with 9 Buy ratings and a consensus score of 4.5263, alongside an average target of $137.90.
8. BWXT — BWX Technologies Inc
Market cap: $17.9B · Quality grade: B · Analyst consensus: 4.2727 (avg target $239.27)
What they do. The company manufactures nuclear components, reactors, fuel, and specialized equipment through Government Operations and Commercial Operations. Its portfolio includes naval nuclear components, research reactor fuel, commercial nuclear steam generators, pressure vessels, reactor components, fuel handling systems, storage containers for spent fuel and high-level waste, and lifecycle support services.
Why it fits. BWX Technologies gives investors a different kind of nuclear exposure than miners or utilities. Instead of betting on uranium prices or wholesale power, shareholders get a manufacturer and service provider tied to reactor components, fuel systems, maintenance, and long-lived nuclear infrastructure, which makes it relevant to both existing fleet support and future build activity.
Numbers that matter. BWXT produced $3.38 billion in revenue, $464.6 million in EBITDA, and a 10.21% profit margin. Its returns are a standout, with ROE of 29.03% and ROA of 5.96%, while margins include 22.7% gross, 10.38% operating, and 10.21% net. Growth has also been healthy, with revenue up 26.1% year over year and earnings up 20.7%. The main quality constraint is valuation and balance-sheet sensitivity, as trailing P/E is 51.87 and forward P/E is 46.51, while the composite debt-equity component scored poorly.
Recent momentum. Few companies in this group have matched BWXT’s earnings consistency. It has beaten estimates in 8 of the last 8 quarters, including EPS of $1.12 versus $0.9257 on May 5, 2026, a 21.0% surprise, and $1.08 versus $0.885 on February 25, 2026, a 22.0% surprise. Analyst sentiment is positive but not unanimous, with 3 Buy, 1 Hold, and 1 Sell rating, and an average target of $239.27.
7. CEG — Constellation Energy Corp
Market cap: $93.5B · Quality grade: B · Analyst consensus: 4.375 (avg target $365.83)
What they do. The company produces and sells electricity, natural gas, and energy-related products across five segments: Mid-Atlantic, Midwest, New York, ERCOT, and Other Power Regions. Constellation has approximately 31,676 megawatts of generating capacity spanning nuclear, wind, solar, natural gas, and hydroelectric assets, serving utilities, municipalities, cooperatives, and commercial, industrial, public-sector, and residential customers.
Why it fits. Constellation is one of the most direct large-cap ways to invest in nuclear-powered electricity generation rather than the fuel cycle. In a market focused on clean baseload power for AI and data-center demand, a major generation fleet with meaningful nuclear exposure is strategically important because it can monetize long-duration power needs directly through electricity sales and customer contracts.
Numbers that matter. Constellation generated $29.87 billion in revenue and $7.96 billion in EBITDA, with a 12.69% profit margin. Profitability is healthy for a utility-style operator, including a 23.3% gross margin, 21.86% operating margin, 12.69% net margin, 16.1% ROE, and 4.2% ROA. Growth has been especially strong, with revenue up 63.8% year over year and earnings growth of 1,091%. Valuation is far more moderate than many nuclear-adjacent names, at about 22.51 times trailing earnings and 22.27 times forward earnings.
Recent momentum. The earnings record is decent rather than spotless, with beats in 4 of the last 8 quarters. The latest print was encouraging: EPS of $2.74 versus $2.27 on May 11, 2026, a 20.7% surprise, after a slight miss in February when EPS of $2.30 came in just below the $2.31 estimate. Analysts lean positive, with 2 Buy and 4 Hold ratings, a consensus score of 4.375, and an average target of $365.83.

6. DUK — Duke Energy Corporation
Market cap: $95.8B · Quality grade: B · Analyst consensus: 3.8 (avg target $139.22)
What they do. The company is a regulated utility operating through Electric Utilities and Infrastructure and Gas Utilities and Infrastructure. Its electric business generates, transmits, distributes, and sells power across the Southeast and Midwest using coal, hydroelectric, natural gas, oil, renewables, and nuclear fuel, while the gas segment serves residential, commercial, industrial, and power-generation customers.
Why it fits. Duke is not a pure-play nuclear stock, but it belongs on the list because nuclear is part of a large, diversified regulated utility platform. For investors who want exposure to the theme with less commodity sensitivity and more defensive cash-flow characteristics, Duke offers a steadier route into the nuclear conversation through an existing utility framework.
Numbers that matter. Duke posted $32.72 billion in revenue, $16.48 billion in EBITDA, and a 15.71% profit margin. Margins are strong, including 51.0% gross, 25.51% operating, and 15.71% net, with ROE of 9.66% and ROA of 2.78%. Growth is modest but stable, with revenue up 11.3% year over year and earnings growth of 12.0%. Valuation is also relatively restrained, at 18.90 times trailing earnings and 18.05 times forward earnings, which supports its middle-of-the-pack ranking.
Recent momentum. Duke has one of the better earnings records in the group, beating in 7 of the last 8 quarters. Most recently, it reported EPS of $1.93 versus $1.77 on May 5, 2026, a 9.0% surprise, following another beat in February with EPS of $1.50 versus $1.49. Analyst sentiment is more cautious than bullish, with 2 Buy and 11 Hold ratings and an average target of $139.22.
5. VST — Vistra Corp.
Market cap: $44.8B · Quality grade: B- · Analyst consensus: 4.2778 (avg target $225.06)
What they do. The company is an integrated retail electricity and power generation business operating through Retail, Texas, East, West, and Asset Closure. Vistra serves about 5 million customers and has approximately 44,000 megawatts of generation capacity across natural gas, nuclear, coal, solar, and battery storage, while also participating in wholesale power, commodity risk management, fuel procurement, and logistics.
Why it fits. Vistra sits at the center of the current nuclear-demand narrative because it combines retail load exposure with nuclear generation assets. The theme’s relevance was underscored by Reuters’ January 2026 report that Meta signed 20-year agreements tied to three Vistra nuclear plants, reinforcing the idea that large technology customers are willing to contract for reliable nuclear-backed power.
Numbers that matter. Vistra generated $19.45 billion in revenue and $6.79 billion in EBITDA, with an 11.53% profit margin. Profitability is strong on several measures, including a 38.6% gross margin, 26.58% operating margin, 11.53% net margin, 42.9% ROE, and 6.02% ROA. Revenue growth was robust at 43.4% year over year, but earnings growth was negative 52.3%, which helps explain the stock’s more mixed quality profile. Valuation is interesting: trailing P/E is 22.21, but forward P/E falls to 14.75, suggesting analysts expect a much stronger earnings base ahead.
Recent momentum. The recent earnings record has been volatile, with beats in only 3 of the last 8 quarters. The latest quarter was a major upside surprise, though, as EPS of $2.87 on May 13, 2026, crushed the $1.28 estimate by 124.2%, following a sharp miss in February when EPS of $0.54 came in well below the $2.30 estimate. Analysts remain constructive overall, with 5 Buy and 2 Hold ratings and an average target of $225.06.
4. LEU — Centrus Energy Corp.
Market cap: $3.4B · Quality grade: C+ · Analyst consensus: 4.5 (avg target $278.64)
What they do. The company supplies nuclear fuel components through two segments: Low-Enriched Uranium and Technical Solutions. Centrus sells separative work units, natural uranium hexafluoride, uranium concentrates, uranium conversion, and enriched uranium products to utilities, while also providing technical, manufacturing, engineering, and operations services to public- and private-sector customers.
Why it fits. Centrus is one of the more direct ways to invest in the fuel-cycle side of the nuclear theme rather than in reactor ownership. As investors focus on tighter fuel-cycle economics and the strategic importance of enrichment-related capabilities, Centrus stands out because its business is tied to the processing and supply chain that sits between uranium production and reactor consumption.
Numbers that matter. Centrus generated $452.3 million in revenue and $34.2 million in EBITDA, with a 13.4% profit margin. Its gross margin was 25.7%, but operating margin was slightly negative at -0.26%, showing how uneven profitability can be beneath the net-income line. Revenue growth was just 4.9% year over year, and earnings growth was negative 71.9%, which is a clear reason the stock does not rank higher on quality. Valuation is demanding as well, at 62.89 times trailing earnings and 66.67 times forward earnings.
Recent momentum. The earnings history is volatile but capable of big upside surprises. Centrus has beaten estimates in 5 of the last 8 quarters, including EPS of $1.05 versus $0.27 on March 31, 2026, a 288.9% surprise, though the prior quarter missed by 41.9%. Analyst coverage is limited but favorable overall, with 1 Buy and 2 Hold ratings, a consensus score of 4.5, and an average target of $278.64.
3. TLN — Talen Energy Corporation
Market cap: $14.8B · Quality grade: D+ · Analyst consensus: 4.6667 (avg target $475.30)
What they do. The company is an independent power producer and infrastructure operator that sells electricity, capacity, and ancillary services into wholesale power markets. Talen owns and operates approximately 13.1 gigawatts of power infrastructure across nuclear, fossil, oil, natural gas, and coal plants.
Why it fits. Talen belongs on a nuclear list because part of its generation fleet is nuclear, giving it exposure to the same clean, around-the-clock power demand that is drawing in data-center and AI-linked interest. At the same time, it is a more complex story than a pure nuclear operator because the broader fleet includes multiple fuel types and its economics are tied to wholesale market conditions.
Numbers that matter. Talen produced $3.24 billion in revenue and $654 million in EBITDA, but its profit margin was negative 0.65%. Operating margin was still a healthy 17.24% and gross margin was 40.1%, yet ROE was negative 1.86%, highlighting the uneven bottom-line picture. Revenue growth was very strong at 96.7% year over year, and earnings growth was 34.5%. The valuation setup is unusual: trailing P/E is not meaningful because EPS is negative $0.52, but forward P/E is 13.79, implying expectations for a major earnings rebound.
Recent momentum. Recent results have been better than the low quality grade suggests. Talen has beaten estimates in 6 of the last 8 quarters, including EPS of 4.3783 versus 4.255 on May 6, 2026, and 4.3849 versus 4.3342 on March 5, 2026. Analysts are notably bullish, with 3 Buy ratings, a consensus score of 4.6667, and an average target of $475.30, but the stock still ranks below the top two because profitability and composite quality metrics remain weak.

2. OKLO — Oklo Inc.
Market cap: $10.2B · Quality grade: C+ · Analyst consensus: 4.1111 (avg target $91.21)
What they do. The company develops fission power plants in the United States and is centered on its Aurora Powerhouse design, which is intended to produce between 15 and up to 75 megawatts of electricity. Oklo is also commercializing nuclear fuel recycling and fuel fabrication technology aimed at converting used nuclear fuel into usable fuel for its reactors.
Why it fits. Oklo is one of the clearest public-market expressions of the small modular reactor and advanced reactor thesis. In a theme increasingly shaped by AI power demand and interest in smaller, more modular deployment models, the company offers direct exposure to the highest-upside and highest-risk corner of nuclear investing.
Numbers that matter. This is still a pre-revenue, development-stage story, so the financial profile looks very different from the utilities and fuel suppliers on this list. Revenue, profit margin, and forward earnings multiples are not available, while EBITDA was negative $172.1 million and trailing EPS was negative $0.84. Profitability metrics are also negative, with ROE of -8.87% and ROA of -7.18%. One relative strength is balance-sheet positioning inside the composite grade, where debt-equity scored 5, but overall quality remains constrained by the lack of current operating earnings.
Recent momentum. Oklo’s earnings history reflects its early-stage status. It has beaten estimates in only 1 of the last 6 reported quarters, with the most recent reported result showing EPS of -$0.27 versus an estimate of -$0.16 on March 17, 2026, a 68.8% miss. Even so, analysts remain constructive on the long-term story, with 2 Buy and 3 Hold ratings, a consensus score of 4.1111, and an average target of $91.21.
1. UEC — Uranium Energy Corp
Market cap: $6.5B · Quality grade: D+ · Analyst consensus: 4.375 (avg target $19.17)
What they do. The company engages in exploration, pre-extraction, extraction, and processing of uranium and titanium concentrates properties in the United States, Canada, and Paraguay. In practical terms, Uranium Energy is a direct upstream uranium exposure, giving investors leverage to the raw material that underpins reactor fuel demand.
Why it fits. If the nuclear theme is partly a uranium-demand story, UEC is one of the most straightforward ways to express that view. It sits at the front end of the supply chain, so it can benefit if reactor life extensions, restarts, and new-build expectations translate into tighter uranium market conditions over time.
Numbers that matter. The current financial profile is weak, which makes its No. 1 ranking here more about thematic purity than present-day fundamentals. Revenue was just $20.2 million, EBITDA was negative $103.8 million, trailing EPS was negative $0.18, and forward P/E was 178.57. Revenue declined 59.4% year over year, earnings growth was negative 80.6%, ROE was -7.12%, and ROA was -5.46%. Gross margin was -349.9% and operating margin was -116.65%, underscoring that this is a high-risk uranium option rather than a proven cash-flow compounder.
Recent momentum. Recent execution has not been strong. Uranium Energy has missed estimates in 8 of the last 8 quarters, including EPS of -$0.0372 versus -$0.0268 on March 18, 2026, and -$0.02 versus -$0.01 on December 10, 2025. Still, analysts remain bullish on the longer-term uranium thesis, with 5 Buy ratings, a consensus score of 4.375, and an average target of $19.17.
Across this list, three distinct nuclear investing buckets stand out. First are fuel-cycle and uranium names such as Cameco, Centrus, and Uranium Energy, which offer direct leverage to reactor fuel demand but can come with sharp valuation swings and uneven earnings. Second are power producers such as Constellation, Duke, Vistra, and Talen, where nuclear matters because it supports reliable baseload generation in an electricity market increasingly shaped by AI, data-center, and long-duration load growth. Third are technology and equipment plays such as Oklo and BWX Technologies, which give exposure to future reactor deployment and nuclear infrastructure. The biggest risk across the theme is that enthusiasm can outrun execution: new nuclear projects are capital intensive, fuel markets can be cyclical, and many stocks already discount a favorable policy and demand backdrop. The most important thing to watch from here is whether today’s narrative converts into durable contracts, improved fuel economics, steadier earnings, and real additions to nuclear capacity rather than just higher investor expectations.
Methodology
This ranking started with a screen for US-listed nuclear-related companies with market capitalizations above $500 million. We then ranked the group on investment quality, emphasizing composite quality grades, profitability, earnings consistency, growth trends, valuation context, and analyst sentiment, while also considering how directly each company participates in the nuclear value chain. The list is presented in countdown order, from No. 9 to the top pick at No. 1, and is intended for monthly updates. Because the goal is durability rather than day-trading relevance, the write-ups focus on evergreen operating and financial metrics instead of short-term market moves.
