Cameco Stock And 2 Nuclear Energy Names Worth A Closer Look

Global markets are on edge as energy costs, inflation worries, and interest rate expectations shift across regions, and many investors are looking for exposure to power sources that are not directly tied to oil and gas prices. Nuclear energy stocks sit at the intersection of reliable baseload power and long term decarbonisation targets, covering uranium suppliers, enrichment facilities, and reactor operators. This screener on nuclear energy stocks filters that broad universe into a focused starting list, and the rest of this article highlights 3 stocks from the tool that stand out for further research.

AtkinsRéalis Group (TSX:ATRL)

Overview: AtkinsRéalis Group is a Montreal based engineering and project management company that works across infrastructure, energy, transportation, defence, and industrial projects, including specialist services across the full nuclear life cycle from new reactor builds to decommissioning and waste management. It also invests in and manages large infrastructure assets such as highways, power facilities, and water treatment plants for governments and private clients worldwide.

Operations: AtkinsRéalis generates the largest share of its CA$11.5b engineering and services revenue from UKI at about CA$2.8b, followed by Nuclear at about CA$2.5b, USLA at about CA$2.1b, Canada at about CA$1.5b, and AMEA at about CA$1.3b.

Market Cap: CA$14.3b

Investors looking at nuclear energy may consider AtkinsRéalis Group a relevant company to follow because it combines a growing nuclear project backlog, including major roles on Sizewell C and CANDU reactor initiatives, with high current profitability and a P/E that sits below many construction peers. The company is emphasizing higher margin engineering and advisory work, while recent partnerships with Indigenous and international firms point to a wider pipeline across power, transport, and defence. At the same time, there are risks around large nuclear contracts, project delays, and reliance on external funding. That mix of significant projects, current pricing, and meaningful execution risk is an important aspect of the company’s profile.

AtkinsRéalis Group’s mix of nuclear contracts, infrastructure assets, and a P/E below many construction peers can look like an underappreciated engine of earnings. However, the real story sits in the 5 key rewards and 3 important warning signs (2 are major!)

Cameco (TSX:CCO)

Overview: Cameco is a Saskatoon based uranium producer and nuclear services company that supplies uranium fuel, conversion, fabrication, and reactor technology through its Uranium, Fuel Services, and Westinghouse segments to power utilities across the Americas, Europe, and Asia.

Operations: Cameco generates most of its revenue from uranium production at about CA$3.0b, supported by around CA$561m from Fuel Services, while its Westinghouse segment is reported at roughly CA$3.6b before unallocated adjustments.

Market Cap: CA$59.2b

Cameco provides exposure to both the raw material side and the technology side of nuclear energy, combining high grade uranium assets such as Cigar Lake with a 49% interest in Westinghouse. This interest is connected to planned AP1000 reactor builds and recent U.S. Department of Energy loan commitments. The stock currently trades at a high P/E, and future expectations are based on meaningful progress on new nuclear projects and long term fuel contracts. Recent production interruptions at Cigar Lake and ongoing supply chain and geopolitical risks highlight how sensitive results can be to operational issues. The balance between these expectations and the risks involved is a key reason some investors may look at Cameco more closely.

Cameco’s mix of uranium production and its Westinghouse stake has investors fixated on the story, but the real tension is how expectations stack up against current pricing in the analysis report for Cameco

Denison Mines (TSX:DML)

Overview: Denison Mines is a Toronto based uranium exploration and development company focused on acquiring, exploring, and advancing uranium bearing properties in Canada, led by its 95% owned Wheeler River project in the Athabasca Basin region of northern Saskatchewan.

Operations: Denison Mines currently generates a small amount of revenue of about CA$4.6m from mining related activities.

Market Cap: CA$4.1b

For investors using the Nuclear Energy Stocks screener, Denison Mines is described as a high risk, high potential uranium developer with a large undeveloped resource base in one of the world’s richest uranium regions. Its flagship project is viewed by some supporters as highly cost competitive. Available forecasts indicate expectations of very strong growth in revenue and earnings and a path to profitability within 3 years. At the same time, current revenue is modest, recent losses are heavy at over CA$100m in Q1 2026, and funding relies on external borrowing. Recent partnership and community support news around Athabasca projects highlights the scale of what is at stake, as well as the amount of work that may still lie ahead for this stock.

Denison Mines looks like a classic high potential uranium story, where forecasts, funding needs, and project timelines intersect, and the real kicker may sit inside the analyst forecasts for Denison Mines
