Nuclear energy stocks sit at the intersection of two big themes investors are watching closely today: reliable power supply and pressure on energy costs. With mixed growth signals across major economies, ongoing geopolitical tensions, and energy price volatility, many investors are looking at Nuclear Energy Stocks as a potential way to gain exposure to companies involved in uranium production, fuel enrichment, and reactor operations for steady baseload power. This article highlights 3 stocks from the Nuclear Energy Stocks screener that stand out on current fundamentals and business exposure within the sector.

Constellation Energy (CEG)

Overview: Constellation Energy is a US-based power producer that supplies electricity, natural gas, and clean energy solutions from a roughly 31,676 megawatt fleet of nuclear, wind, solar, gas, and hydro assets to utilities, businesses, public sector entities, and households. Formed in 2021 and headquartered in Baltimore, it focuses on providing reliable, lower-emission baseload power across key regional markets.

Operations: Constellation Energy generates essentially all of its US$29.9b in revenue from its Generation segment, with earnings spread across regions such as the Midwest, Mid-Atlantic, New York, ERCOT, and other power markets.

Market Cap: US$98.4b

Constellation Energy stands out in nuclear power because its long-term, higher-margin contracts with data centers and large corporates are tied to demand for round-the-clock, carbon-free electricity. Recent deals with companies such as Walmart and Microsoft highlight that appeal. Federal support for nuclear production tax credits and zero-emission credits provides a degree of visibility on future cash flows. In addition, the restart of the Three Mile Island (Crane) unit and the US$16.4b Calpine acquisition add scale and potential synergies. At the same time, high debt levels, reliance on large centralized nuclear assets, and customer concentration mean investors need to watch regulatory shifts and funding conditions closely. This is where the full story on Constellation’s risk and reward trade-off becomes more nuanced.

Constellation Energy’s contracts with data centers and corporates could be masking a far more complex risk reward profile, so it is worth scanning the 4 key rewards and 2 important warning signs to see what might shift the story next.

American Electric Power Company (AEP)

Overview: American Electric Power Company is a large US utility that generates electricity from a mix of coal, nuclear, gas, and renewables, then transmits and distributes that power to retail and wholesale customers across its regulated service territories. With roots back to 1906 and headquarters in Columbus, Ohio, it also runs energy marketing and trading operations alongside its core grid infrastructure business.

Operations: American Electric Power Company generates the bulk of its roughly US$22.4b in revenue from Vertically Integrated Utilities (US$13.1b) and Transmission and Distribution Utilities (US$6.2b), with additional contributions from AEP Transmission Holdco and Generation & Marketing, all within the United States.

Market Cap: US$70.9b

American Electric Power Company gives investors direct exposure to the rising power needs of data centers, with a 56 GW incremental load pipeline and a capital plan that aims to expand its regulated grid footprint. Earnings grew 32.2% over the past year and profit margins improved. Most earnings now come from regulated transmission and distribution, which can provide more predictable cash flows than merchant generation. On the other hand, the dividend is not well covered by free cash flow and the balance sheet leans heavily on external funding, so interest rates and refinancing conditions matter. For investors weighing whether this premium valued “AI era grid” story still stacks up on risk and reward, the details under the hood become crucial.

American Electric Power Company’s rapidly expanding data center load and sizeable capital plan could be masking a more complex funding story, so it is worth reviewing the American Electric Power Company financial health report to see what might really be driving future flexibility and pressure.

GE Vernova (GEV)

Overview: GE Vernova is an energy infrastructure company that designs and services equipment and software used to generate, move, and manage electricity worldwide, spanning gas and nuclear power, wind turbines, grid hardware, and grid-intelligence solutions. It positions itself as a key supplier to utilities and data center operators that need reliable power and smarter grids to support AI, electrification, and renewable integration.

Operations: GE Vernova generates most of its revenue from Power at US$20.3b, alongside Wind at US$8.7b and Electrification at US$10.8b, with a small negative contribution from Eliminations and Other.

Market Cap: US$303.0b

Investors watching nuclear and AI-linked energy plays may find GE Vernova interesting because it sits at the heart of rising electricity demand and is reporting strong current fundamentals. The Power segment is anchored by thousands of installed gas turbines and over US$31b of unearned service revenue, which supports recurring cash flows. Recent data center orders have reportedly exceeded 2025 levels in a single quarter. Earnings and margins have improved sharply, with current net profit margin at 23.8% and ROE reported at 62.2%. The stock is reported to trade on a P/E below both industry and peer averages. On the other hand, the Wind segment still drags on profitability, the company shows high reliance on external borrowing, and there has been significant insider selling. These are all factors investors may wish to scrutinize more closely.

GE Vernova’s accelerating orders, sizeable service backlog, and reported P/E below peers hint that the market may be underestimating its story, yet the pressure from Wind and insider selling raises questions the analysis report for GE Vernova
