Share
Listen to the news

With global bond markets under pressure, energy prices sensitive to geopolitical shocks and central banks weighing further rate moves, many investors are looking more closely at reliable power sources and how they fit into long term portfolios. The Nuclear Energy Stocks screener focuses on companies linked to uranium supply, enrichment and nuclear reactors that aim to provide steady, large scale electricity with low direct emissions. This article highlights 3 stocks from that screener, helping you quickly spot different ways to get exposure to the nuclear energy theme while keeping an eye on inflation, energy security and trade trends.

AtkinsRéalis Group (TSX:ATRL)

Overview: AtkinsRéalis Group is a Montreal based engineering and project management company that works across infrastructure, transportation, water, defence, power and renewables, with a major focus on nuclear projects from design and construction through to decommissioning and waste management. It also invests in and manages large assets such as bridges, highways, power facilities and mass transit systems, combining technical services with capital solutions for governments and corporates worldwide.

Operations: AtkinsRéalis Group generates most of its CA$11.5b in segment revenue from Engineering Services in the UKI (CA$2.8b), USLA (CA$2.1b) and Canada (CA$1.5b), with a sizeable Nuclear segment of about CA$2.5b and additional contribution from AMEA (CA$1.3b) and segment adjustments.

Market Cap: CA$14.3b

AtkinsRéalis Group stands out in nuclear infrastructure because it combines a sizeable CA$2.5b nuclear segment with a broad engineering footprint across transport, water and power. This is backed by a large nuclear and infrastructure project backlog that supports long term revenue visibility. The stock currently trades on a low P/E versus peers and analysts see upside to their consensus price target. However, earnings are expected to contract and margins may be pressured as non cash items normalize, so investors need to weigh current strength in profitability against forecast declines. Recent moves in advanced nuclear, including CANDU licensing steps in the US and new UK frameworks, underline how central AtkinsRéalis could be to future low carbon power build out. Reliance on large, complex contracts and external funding means execution risk remains front of mind.

AtkinsRéalis looks like a rare mix of nuclear scale, diversified engineering revenue and a P/E that sits below peers, but that setup only matters if the medium term story holds. Tap into the analyst forecasts for AtkinsRéalis Group and see what expectations might be missing.

NexGen Energy (TSX:NXE)

Overview: NexGen Energy is a Vancouver based uranium explorer and developer that owns 100% of the Rook I project in Saskatchewan’s Athabasca Basin, a large uranium district in Canada. The company focuses on proving up and advancing high grade uranium resources that could one day feed global nuclear fuel supply.

Market Cap: CA$8.6b

NexGen Energy attracts attention because it sits on the Rook I project, which management is positioning as a future supplier of more than 20% of global nuclear fuel. The business is still pre revenue and unprofitable with a negative ROE of 24.43%. Recent drill results at Patterson Corridor East point to continued high grade uranium potential, and the Rook I construction permit followed a long regulatory process. This potential upside comes with clear funding and execution risk, as the company relies on higher risk borrowing and has seen share dilution and insider selling. For investors willing to accept those trade offs, the mix of experienced leadership, active development work and a large resource base makes NexGen a high risk, high potential nuclear pure play to watch closely.

NexGen Energy’s high grade uranium story is gaining attention, but the real tension is between its potential scale and funding risk. For the full picture, see the 1 key reward and 4 important warning signs (1 is major!)

Denison Mines (TSX:DML)

Overview: Denison Mines is a Toronto based uranium exploration and development company that holds a 95% interest in the Wheeler River project in Saskatchewan’s Athabasca Basin, working to turn high grade uranium resources into future production for the nuclear fuel market.

Operations: Denison Mines currently generates around CA$4.6m in revenue, primarily from its Mining segment.

Market Cap: CA$3.9b

Denison Mines may appeal to investors seeking pure uranium exposure linked to the Athabasca Basin, with the Wheeler River project and a suite of joint ventures that keep it close to new discoveries and regional activity. The company is currently loss making, reliant on higher risk funding, and has limited current revenue, so investor expectations play a significant role in how the stock is viewed. A key consideration is whether the broader uranium narrative and Denison’s project pipeline adequately support those expectations.

Denison Mines sits at the crossroads of pure uranium exposure and high investor expectations. The real story shows up once you unpack its project pipeline and funding trade offs with the analysis report for Denison Mines
