Key takeaways
- Nuclear demand is accelerating fast: Between AI data centers consuming massive amounts of power and governments pushing to triple nuclear capacity by 2050, the supply-demand setup for uranium and nuclear services is about as strong as I’ve seen it in years.
- Diverse ways to play it: Canadian-listed nuclear stocks give you exposure across the entire value chain, from uranium miners and fuel processors to engineering firms designing next-gen reactors and pipeline operators moving into nuclear power generation. That variety lets you pick your spot based on your risk tolerance.
- Uranium price swings are real: These stocks are tied to a commodity that can be wildly volatile, and many of the smaller names aren’t yet profitable or are still in development stages. If uranium prices pull back or reactor buildout timelines slip, the downside can be sharp, so position sizing matters a lot here.
Nuclear energy is having a moment, and for once, the hype is backed by something real. Global electricity demand is surging, driven by AI data centers, electrification, and the simple reality that the world needs a lot more baseload power that doesn’t rely on the weather. Wind and solar can’t run 24/7. Natural gas has its own geopolitical baggage. Nuclear checks both boxes: it’s clean, and it’s always on.
Canada is uniquely positioned here. We’re one of the largest uranium producers on the planet, we have decades of CANDU reactor expertise, and there’s a growing pipeline of small modular reactor (SMR) projects that could reshape how nuclear gets deployed. This isn’t just a commodity story. It spans the full value chain, from the miners pulling uranium out of the ground to the engineering firms designing and building the reactors themselves, to the utilities transporting the power those reactors generate.
What’s changed recently is the political will. Governments that spent years tiptoeing around nuclear are now openly embracing it. Contracts are getting signed. Funding is flowing. Even the defense sector is intersecting with nuclear through government procurement and national security priorities. That kind of policy shift doesn’t reverse easily.
The investment case isn’t without risk, though. Uranium prices are volatile. Reactor projects have a long history of delays and cost overruns. And some of these stocks have already priced in a lot of optimism. Separating the companies with real earnings power from the ones trading purely on narrative is the whole game here.
I looked for businesses with actual revenue, clear ties to nuclear growth, and balance sheets that can handle the long development timelines this industry demands. Some of these are blue chips you’d recognize instantly. Others are smaller names that fly under the radar. The range is wide, and so is the risk spectrum.

Competitive Edge
- AtkinsRealis is one of only a handful of global firms with full-scope nuclear engineering capability, including CANDU reactor expertise. With the global nuclear renaissance accelerating (SMRs, life extensions, new builds), this is a decades-long structural tailwind with high barriers to entry.
- The strategic pivot from lump-sum turnkey (LSTK) EPC projects to cost-reimbursable services fundamentally changes the risk profile. Services revenue now exceeds C$10.8B vs C$153M in LSTK, virtually eliminating the fixed-price contract blowup risk that plagued SNC-Lavalin.
- The Atkins acquisition gave the company a dominant UK/Middle East engineering services franchise with deep government relationships. UK infrastructure spending (HS2 successor projects, defense, Hinkley Point C) provides a sticky, recurring revenue base.
- Linxon, the electrical substation turnkey business, is riding the global grid modernization and electrification wave. Revenue grew 44.6% in FY2024 and 16.1% in FY2025, with EBIT margins improving from breakeven to 5.7%, showing the unit is reaching scale.
By the Numbers
- Total shareholder yield of 11.9% is exceptional, driven by 6% buyback yield and 5.9% debt paydown yield. With a token 0.5% payout ratio, nearly all capital return is through share shrinkage and balance sheet repair, the most tax-efficient combination.
- Nuclear segment revenue compounded from C$905M to C$2.3B over four years (FY2021-FY2025), a 26% CAGR, with adjusted EBIT margins expanding from 15% to 11.2%. This segment now represents 21% of total revenue vs 12% four years ago, fundamentally reshaping the business mix.
- SNCL Services adjusted EBIT grew from C$581M to C$1.04B over three years (FY2022-FY2025), a 21% CAGR, while the legacy LSTK Projects losses narrowed from C$303M to C$112M. The toxic EPC tail is shrinking and the services engine is scaling.
- Net debt/EBITDA is effectively zero at -0.29x, meaning the company has more cash than debt on a net basis. Combined with OCF-to-debt coverage of 53%, the balance sheet is the cleanest it has been since the SNC-Lavalin era scandals.
- Backlog surged 21.5% YoY to C$21.2B in FY2025, representing roughly 1.9x trailing revenue. This is the fourth consecutive year of double-digit backlog growth, providing multi-year revenue visibility that de-risks forward estimates.
Risk Factors
- Trailing P/E of 6.1x vs forward P/E of 23.4x signals that trailing EPS of C$15.44 is heavily inflated by non-recurring items. Estimated Y1 EPS of C$3.95 implies normalized earnings are 75% lower, so the stock is not actually cheap on a forward basis.
- FCF-to-net-income conversion of just 11% is alarmingly low. FCF margin is only 2.6% vs a 23.4% net margin, a 9x gap. This confirms the trailing net income figure includes large non-cash gains or one-time items that massively overstate cash earnings quality.
- LSTK Projects lost C$112M on just C$153M of revenue in FY2025, an implied negative 73% EBIT margin. Q4 alone saw a C$59M loss, a 205% QoQ deterioration, suggesting remaining fixed-price contracts are still generating outsized charges.
- DSO of 127 days is very high for an engineering services firm and implies roughly C$3.8B in receivables. With receivables turnover at just 2.9x, working capital is absorbing cash that should be flowing to shareholders.
- Gross margin of 8.8% and operating margin of 4.7% are thin even by E&C standards. With SBC at 1.2% of revenue, stock comp consumes roughly 25% of operating income, a meaningful drag on real economic profitability.

Competitive Edge
- Aecon's nuclear capabilities (Darlington refurbishment, SMR positioning) represent a scarce competency in Canada. With Ontario's nuclear expansion plans and federal clean energy mandates, this is a decades-long tailwind with very few qualified competitors.
- U.S. revenue grew from $35M to $627M over four years (92.6% YoY most recently), diversifying away from Canadian infrastructure budget cycles. The U.S. Infrastructure Investment and Jobs Act provides a multi-year federal spending floor.
- The strategic pivot away from fixed-price contracts is a direct management response to the FY2023-FY2024 margin destruction. This is not just rhetoric; the revenue mix data confirms execution, reducing repeat risk of cost overruns on lump-sum projects.
- Aecon's position across civil, nuclear, utilities, and urban transit creates cross-selling optionality on mega-projects where integrated capabilities reduce owner procurement complexity and create switching costs mid-project.
By the Numbers
- Consolidated backlog surged 60.8% YoY to $10.7B, with $5.0B beyond 24 months (up 110% YoY). That is roughly 2x trailing revenue, providing exceptional multi-year visibility rarely seen in Canadian E&C.
- Construction EBITDA exploded from $34.2M to $220.4M (up 544% YoY), signaling the problematic fixed-price legacy projects are rolling off. Construction EBITDA margin recovered to ~4.1% from 0.8%, still below the ~5.4% achieved in FY2021.
- Cost-plus/unit price revenue now represents 68% of construction mix (up from 38% in FY2021), a deliberate de-risking that should structurally compress earnings volatility and reduce the fixed-price blowup risk that crushed FY2023-FY2024.
- Net debt is actually negative at -$49M (net cash position), with $7.66 cash per share. For a company that just went through a severe earnings trough, carrying net cash rather than distressed leverage is a meaningful positive.
- PEG of 0.18 against forward EPS estimates ramping from $0.23 trailing to $1.43/$1.83/$1.97 over three years implies the market is pricing in recovery but still discounting the magnitude of the earnings inflection.
Risk Factors
- Trailing payout ratio of 172% on $0.23 EPS is unsustainable on an earnings basis. FCF payout ratio of 32.5% provides cover, but the $0.95/share dividend requires continued strong cash conversion that may not hold as working capital grows with the backlog ramp.
- Buyback yield is -5.3%, meaning the company is issuing shares. Combined with $36.4M in SBC (6.5% of revenue, or 105% of trailing net income), shareholder dilution is actively eroding per-share economics despite the earnings recovery.
- Interest coverage at 3.0x is thin for a construction company entering a massive backlog execution phase. With $458M in total debt and rates elevated, any project-level cash flow hiccups could pressure this ratio further.
- FCF declined 78% YoY and the 3-year FCF CAGR is -50%, even as revenue grew. The FCF-to-net-income ratio of 5.4x looks strong but is misleading because net income is near zero. As earnings normalize, this ratio will compress sharply.
- DSO of 136 days is extremely elevated for construction. Receivables turnover of 2.7x suggests either slow-paying public sector clients or disputed claims. With revenue ramping 28%, any further DSO expansion would create a significant working capital drag.

Competitive Edge
- Cameco controls two of the world's highest-grade uranium deposits (McArthur River/Key Lake and Cigar Lake in Saskatchewan), giving it a structural cost advantage that Kazatomprom's ISL operations and Orano's Niger assets cannot replicate in tier-one jurisdictions.
- The Westinghouse acquisition creates a vertically integrated nuclear fuel cycle player. Owning reactor technology, fuel fabrication, and uranium supply locks in customers across 30+ year reactor lifespans, creating switching costs no pure-play miner can match.
- Nuclear is increasingly classified as clean baseload energy by the EU taxonomy and U.S. IRA. With 60+ reactors under construction globally and China targeting 150 GWe by 2035, the demand runway extends well beyond the current contracting cycle.
- Saskatchewan's political stability, established regulatory framework, and skilled labor pool create a jurisdictional moat. Competitors in Niger (Orano), Namibia (Paladin), and Kazakhstan face geopolitical risks that periodically disrupt supply and benefit Cameco's pricing.
- Long-term contract book provides revenue visibility. With 33M lbs in annual uranium sales at escalating realized prices, Cameco captures upside from spot price increases while maintaining a floor through fixed-price and market-related contracts.
By the Numbers
- Net cash position of C$113M with OCF-to-debt ratio of 1.28x means Cameco could retire all C$997M in total debt in under a year from operations alone, giving exceptional financial flexibility in a capital-intensive mining sector.
- FCF-to-net-income ratio of 1.42x signals high earnings quality. Cash generation consistently exceeds reported profits, which is rare for miners where capex often consumes operating cash flow.
- Uranium average realized price climbed from C$43.34/lb in FY2021 to C$87/lb in FY2025, a 101% increase, while contracted sales volumes held steady around 33M lbs. This pricing power flows almost entirely to the bottom line given fixed-cost mine operations.
- Fuel Services gross margin expanded sharply in FY2025, with gross profit surging 64.2% on only 22.5% revenue growth. This implies significant operating leverage as conversion capacity utilization rises toward 14M kgU production.
- Current ratio of 3.08x and cash ratio of 1.53x are unusually strong for a miner. With C$1.1B in cash against near-term obligations, Cameco can self-fund the 102% surge in uranium capex (C$268M) without accessing capital markets.
Risk Factors
- At 101x trailing P/E, 73x EV/EBITDA, and 18.6x EV/Sales with a PEG of 13.6x, the stock prices in a decade of perfect execution. Even on Y3 consensus EPS of C$3.28, the forward P/E is still 46x, leaving no margin for error.
- Uranium production fell 10.3% YoY to 21M lbs in FY2025 while capex doubled to C$268M. This divergence between rising investment and falling output suggests either operational challenges at McArthur River/Cigar Lake or pre-investment for future capacity that won't pay off near-term.
- Revenue growth decelerated sharply from 24.3% to 7.4% in uranium and from 27.6% to 4.5% in the Americas. The 1.6% total revenue growth against 10.4% EPS growth was driven by margin expansion, not volume, which has a ceiling.
- WEC segment (Westinghouse) posted C$54M EBT on C$3.46B revenue, a 1.6% margin, after losing C$280M the prior year. The C$206M capex burden and volatile quarterly EBT swings (Q4 FY2025 at negative C$61M) suggest integration is far from complete.
- FCF declined 16.9% YoY despite earnings growth, and FCF conversion trend is flagged at -1. With capex-to-depreciation at 1.18x and rising, the gap between reported earnings and cash available to shareholders is widening.

Competitive Edge
- TC Energy's NGTL and Mainline systems are effectively irreplaceable infrastructure with regulated, cost-of-service returns. New pipeline construction in Canada faces near-impossible permitting timelines, creating a permanent barrier to entry for competitors.
- The Southeast Gateway pipeline in Mexico, now largely complete, locks in 25-year USD-denominated take-or-pay contracts with CFE. This provides inflation-protected, sovereign-backed cash flows with minimal volume risk, a rare combination in emerging market infrastructure.
- The Liquids Pipelines spinoff into South Bow in late 2024 simplifies the story into a pure-play natural gas and power company, directly aligned with the LNG export buildout and data center power demand thesis that institutional capital is chasing.
- TC Energy's US gas pipeline network, including Columbia Gas and ANR, sits at the intersection of Appalachian supply and Gulf Coast LNG demand. As US LNG export capacity doubles by 2028, utilization and recontracting rates on these pipes should structurally improve.
- Rate-regulated returns on roughly 95% of EBITDA provide earnings visibility that most energy companies cannot match. Regulatory lag exists, but the flip side is that downturns in commodity prices have minimal direct impact on cash flows.
By the Numbers
- Mexico Natural Gas Pipelines EBITDA surged 36.6% YoY to C$1.365B while capex plunged 76.6% to C$522M, signaling the Southeast Gateway pipeline is transitioning from capital sink to cash generator. This segment's EBITDA margin now exceeds 94%, the highest in the portfolio.
- OCF-to-net-income ratio of 2.11x indicates strong earnings quality for a regulated pipeline, with depreciation and deferred taxes providing substantial non-cash cushion. FCF-to-net-income of 0.93x confirms cash earnings are real despite the capital-intensive model.
- US Natural Gas Pipelines revenue jumped 12.7% YoY to C$7.145B in FY2025, the fastest growth since FY2022, driven by new rate settlements and expansion projects. This segment alone generates 47% of total revenue and 45% of comparable EBITDA.
- SG&A-to-revenue of just 5.5% reflects the operating leverage inherent in a pipeline network. Once pipes are in the ground, incremental throughput drops almost entirely to EBITDA, which is why operating margins sit at 44.8% despite modest top-line growth.
- Canadian Natural Gas Pipelines EBIT recovered from negative C$90M in FY2023 to C$2.164B in FY2025, a full normalization after the Keystone-related impairments. The segment now earns a 37.4% EBIT margin on C$5.785B of revenue.
Risk Factors
- Net debt-to-EBITDA of 6.08x is elevated even for a regulated utility, and with interest coverage at only 3.19x, the cost of servicing C$61.8B in total debt is consuming roughly a third of operating earnings. Refinancing risk is real if rates stay elevated.
- Unlevered FCF is negative C$126M, meaning the business cannot fund its capital program from operations alone without relying on debt or asset sales. The Liquids Pipelines spinoff (South Bow) removed a cash-generating segment, compounding this pressure.
- Payout ratio of 106% on earnings means the dividend is not covered by net income. Even the FCF payout ratio of 93.2% leaves almost no margin of safety, and FCF itself has declined at a negative 29.7% CAGR over five years.
- Current ratio of 0.65 and quick ratio of 0.33 signal short-term liquidity is tight. The company holds only C$1.04 per share in cash against C$4.60 per share in annual capex, relying heavily on credit facilities and capital market access.
- Power & Energy Solutions EBITDA dropped 17% YoY to C$1.008B while revenue fell 11.4%, and quarterly EBIT shows continued sequential weakness. This was previously a growth segment, and the reversal suggests power market conditions or contract roll-offs are biting.

Competitive Edge
- Wheeler River's Phoenix deposit is the highest-grade undeveloped uranium deposit globally, and Denison's planned in-situ recovery (ISR) method would make it the lowest-cost uranium mine in the Athabasca Basin, a structural cost advantage over conventional mining peers like Cameco and NexGen.
- The 22.5% stake in the McClean Lake mill provides built-in processing infrastructure without needing to build a standalone mill, removing a major capex and permitting risk that competitors like NexGen's Rook I project still face.
- Uranium's supply-demand fundamentals are tightening as global nuclear restarts accelerate (Japan, France, US policy shifts) while Kazatomprom and Cameco have guided flat-to-lower production. Denison is positioned to enter production into a structurally undersupplied market.
- ISR mining in the Athabasca Basin is a first-of-its-kind approach that, if proven at Phoenix, could unlock a new extraction paradigm for high-grade deposits, giving Denison a technological moat and potential licensing optionality.
- The 95% ownership of Wheeler River means minimal joint venture friction and near-full capture of project economics, unlike many Athabasca peers who operate under complex JV structures with Cameco or Orano.
By the Numbers
- Current ratio of 13.8x and cash per share of $0.62 vs. book value of $0.29 means Denison holds more cash than its entire equity base, providing exceptional liquidity runway through the pre-production development phase without forced dilution.
- Analyst estimates project a dramatic revenue inflection from $4.9M trailing to $446M in Y3 and $1.1B in Y5, implying Wheeler River's ISR production ramp could transform this from a cash-burning explorer into a substantial producer within 3-4 years.
- EPS trajectory from -$0.24 trailing to +$0.12 in Y3 and +$0.59 in Y5 implies the market is pricing in roughly $0.45 of peak earnings power at ~10x forward P/E on Y5 estimates, which is cheap for a high-grade uranium producer if execution delivers.
- FCF-to-net-income conversion of 0.84x is actually reasonable for a pre-revenue miner, suggesting the losses are real cash burns tied to development spending rather than non-cash accounting distortions inflating the loss figure.
- Tangible book equals total book at $0.29/share with zero intangibles/goodwill, meaning the balance sheet is clean mineral assets and cash with no acquisition premium risk or impairment overhang.
Risk Factors
- SBC-to-revenue of 113% means stock compensation alone is $5.3M against just $4.9M in trailing revenue. Even as revenue scales, this signals a management team accustomed to paying itself in equity, and dilution will compound unless SBC is reined in as production begins.
- Debt-to-equity of 2.8x with interest coverage of -0.17x is alarming. The $730M total debt against $261M equity and negative EBITDA means Denison cannot service its debt from operations. Any delay in Wheeler River's timeline could force dilutive financing.
- Shares grew 0.4% YoY while buyback yield is -0.1%, confirming net dilution. With SBC running at 113% of revenue and no buybacks offsetting it, per-share economics are quietly eroding during the critical pre-production period.
- Revenue declined 5.5% YoY and the 5-year CAGR is -25.3%, showing the existing toll milling and management fee revenue base is shrinking, not growing. The company is entirely dependent on Wheeler River delivering as modeled.
- EBITDA deteriorated 47.8% YoY with the 3-year CAGR at -49.3%, meaning cash burn is accelerating as development spending ramps. The gap between the current burn rate and the estimated production timeline creates meaningful financing risk.
Nuclear is one of the few sectors where the investment thesis and the political thesis actually point in the same direction right now. That’s rare. Usually when governments get excited about something, the economics are shaky. Here, the economics were already improving before the policy tailwinds kicked in. That combination is what makes this group interesting to me, not just as a trade, but as a multi-year allocation.
My biggest concern is crowding. A lot of money has rushed into anything with a nuclear label, and not all of it is being deployed thoughtfully. Some of these stocks are priced for a future that’s still years away from showing up in earnings. Others are already generating real cash flow and just happen to benefit from the same theme. Knowing which is which is the difference between making money and bagholding a narrative.
I’d focus on the names where the business works even if nuclear enthusiasm cools for a quarter or two. That’s your margin of safety in a sector where timelines are measured in decades, not quarters.
