With inflation, energy costs and interest rate decisions all pulling at markets, many investors are looking for themes that focus on essential services and long term infrastructure. Nuclear energy stocks sit at the intersection of power reliability and energy security, spanning uranium producers, enrichment facilities and reactor operators that support baseload electricity. This Nuclear Energy Stocks screener filters that broad universe into a more targeted list and helps you focus your research on companies directly tied to the theme. In this article, you will see three stocks from the screener that stand out for further, independent analysis.

AtkinsRéalis Group (TSX:ATRL)

Overview: AtkinsRéalis Group is a Montreal based engineering and project management company that designs, builds and maintains critical infrastructure, from transport and water systems to power, renewables and defence assets. It also invests in large projects such as bridges, highways and energy facilities. It has a major nuclear services arm covering the full reactor life cycle, from new build and refurbishment to decommissioning and waste management.

Operations: AtkinsRéalis Group generates most of its CA$11.5b in business segment revenue from Engineering Services in the UKI (CA$2.8b), USLA (CA$2.1b) and Canada (CA$1.5b), along with a sizeable Nuclear segment (CA$2.5b). Geographically, the United Kingdom (CA$3.4b) and Canada (CA$2.9b) are its largest markets.

Market Cap: CA$13.2b

Investors looking at nuclear energy as a long term theme may find AtkinsRéalis Group interesting because it couples deep nuclear expertise with wider infrastructure work and a large contracted backlog tied to government backed energy and transport programs. The company reports high current profitability, strong return on equity and recent wins such as the EDF Sizewell C framework and EAGL 1 small modular reactor alliance, which support its role across the nuclear life cycle. At the same time, there are questions around reliance on large nuclear contracts, earnings quality, insider selling and execution on lump sum projects and acquisitions. That mix of opportunity and risk may prompt some investors focused on nuclear and critical infrastructure to take a closer look at AtkinsRéalis Group.

AtkinsRéalis Group’s nuclear reach, government backed contracts and current profitability could be masking some underappreciated tension between opportunity and risk, so it is worth lining up that story against the 5 key rewards and 3 important warning signs (2 are major!)

Constellation Energy (CEG)

Overview: Constellation Energy is a US based power producer that sells electricity, natural gas and clean energy solutions to utilities, municipalities, businesses and households, backed by a roughly 31.7 GW generation fleet spanning nuclear, wind, solar, gas and hydro. The company positions its largely carbon free nuclear capacity as a reliable source of baseload power for large customers such as data centers and corporates that want round the clock low carbon energy.

Operations: Constellation Energy generates about US$29.9b in revenue from its Generation segment, with sales spread across Midwest, Mid Atlantic, New York, ERCOT and other US power regions.

Market Cap: US$97.9b

Investors watching the Nuclear Energy Stocks screener may find Constellation Energy compelling because its long dated, higher margin contracts with hyperscalers and large corporates are tied directly to demand for carbon free, always on power. These contracts are underpinned by federal nuclear tax credits and the Calpine acquisition, which expands its fleet toward 60 GW. At the same time, high debt, reliance on regulated nuclear assets and exposure to a handful of large data center customers raise questions about future capital needs, regulatory decisions and concentration risk. With earnings, margins and analyst targets pointing to a business that many see as more than a plain vanilla utility, there is more to unpack in how Constellation balances durable nuclear cash flows against these structural risks.

Constellation Energy’s accelerating shift toward long dated, higher margin clean power contracts is only half the story. The real puzzle is how those nuclear backed cash flows stack up against the 4 key rewards and 2 important warning signs

GE Vernova (GEV)

Overview: GE Vernova is an energy technology company that supplies the equipment and software needed to generate, move, manage, and store electricity worldwide, from gas and nuclear power plants to wind farms and digital grid systems. Its products and services support utilities, governments, and large industrial customers that require reliable power for everything from AI data centers to national grids.

Operations: GE Vernova generates most of its revenue from Power at US$20.3b, with additional contributions from Electrification at US$10.8b and Wind at US$8.7b, partly offset by US$0.4b of eliminations and other items.

Market Cap: US$298.2b

Investors looking at nuclear and broader electricity infrastructure may see GE Vernova as a way to tap into rising power demand from AI data centers and grid upgrades, supported by a large installed base of gas turbines and a US$163.3b services backlog that supports recurring revenue. Earnings growth has been very strong recently, margins have moved into positive territory, and the company is building out a full stack across generation, transmission, and grid software, including AI driven tools such as GridOS. However, the Wind segment, reliance on external funding, high non cash earnings, and insider selling keep execution risk firmly on the table. The key issue is whether GE Vernova can sustain this shift toward higher quality, cash rich growth across Power and Electrification.

GE Vernova’s shift toward higher quality, cash rich growth across Power and Electrification looks like only part of the picture, and the real story sits inside the analyst forecasts for GE Vernova.
