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 I don’t think it’s a fad. The conversation around power generation has fundamentally changed over the last few years. Governments that were shutting down reactors a decade ago are now scrambling to extend their lifespans or build new ones. The reason is simple: you can’t electrify everything, power a wave of AI data centers, and hit emissions targets without a reliable baseload source that runs 24/7. Wind and solar can’t do that alone. Nuclear can.
Canada sits in a unique position here. We’re one of the world’s largest uranium producers, we have deep expertise in reactor technology through CANDU, and we’ve got companies involved at every stage of the nuclear fuel cycle. That’s not something you can say about many countries. From mining the raw material to engineering the plants, the Canadian market gives you real exposure to this theme without having to go hunting on foreign exchanges.
The demand picture is staggering. Between restarts of idled reactors in the U.S., new builds across Asia, and small modular reactor programs gaining traction in Canada and abroad, the appetite for uranium and nuclear services is growing faster than supply can keep up. Uranium prices have reflected that, and contract volumes are climbing as utilities lock in long-term supply agreements they’d been putting off for years.
Still, this isn’t a sector where you can just throw a dart. Some of these companies are large-cap blue chip names with diversified revenue streams. Others are junior miners that won’t produce a pound of uranium for years. The risk profiles are wildly different, and the gap between a quality operator and a speculative bet is massive. A name like TC Energy, for example, brings utility-like stability to the table, while a pure-play miner carries far more commodity exposure.
I focused on companies with clear ties to the nuclear value chain, whether that’s through uranium production, fuel processing, reactor engineering, or power generation. Quality of the business model mattered more to me than how “nuclear” the name sounds.

Competitive Edge
- Cameco controls two of the world's highest-grade uranium deposits (McArthur River/Key Lake and Cigar Lake) in the politically stable Athabasca Basin. Grade advantage translates to structurally lower all-in sustaining costs versus peers like Kazatomprom or Paladin.
- The Westinghouse acquisition creates a vertically integrated nuclear fuel company spanning mining, conversion, enrichment services, and reactor technology. No other Western company offers this full-stack capability, creating cross-selling leverage with utility customers.
- Global nuclear capacity additions (China building 20+ reactors, US/EU extending plant lifetimes, SMR development) create a structural demand tailwind. Cameco's long-term contract book locks in pricing while spot exposure provides upside optionality.
- Western utility buyers face growing urgency to de-risk supply chains away from Russian and Kazakh uranium. Cameco is the largest non-Russian aligned producer, making it the default counterparty for security-of-supply mandated procurement.
- Saskatchewan's regulatory and permitting framework is among the most mining-friendly globally, with established Indigenous partnership agreements. This reduces the political risk that has stranded uranium projects in Africa and Australia.
By the Numbers
- Net cash position of C$218M with OCF-to-debt ratio of 1.41x means Cameco could retire all outstanding debt in under 9 months from operating cash flow alone, giving exceptional financial flexibility in a capital-intensive commodity business.
- FCF margin of 30.9% dwarfs net margin of 16.9%, with FCF-to-net-income conversion at 1.82x. This signals high earnings quality where reported profits significantly understate cash generation, partly due to non-cash charges flowing through the WEC consolidation.
- Uranium average realized price climbed from C$43.34/lb in FY2021 to C$87/lb in FY2025, a 101% increase, while production volumes tripled from 6.1M to 21M lbs. The simultaneous expansion of both price and volume is rare in commodity businesses and reflects disciplined supply management.
- Fuel Services gross profit surged 64.2% YoY on only 22.5% revenue growth, implying margin expansion from 23.1% to 30.9%. This segment is hitting operating leverage as conversion capacity utilization rises toward nameplate.
- 3-year FCF CAGR of 99.2% and 3-year EPS CAGR of 83.1% dramatically outpace the 23.1% revenue CAGR, demonstrating powerful operating leverage as fixed-cost mining operations scale into higher uranium prices.
Risk Factors
- At 111x trailing P/E, 71.6x EV/EBITDA, and 18.8x P/S, Cameco trades at extreme multiples even for a commodity upcycle. The 0.8/10 Valuation grade confirms the stock is pricing in years of uranium price appreciation that may not materialize.
- Uranium production fell 10.3% YoY to 21M lbs in FY2025 while capex doubled (+101.9% to C$268M). This divergence suggests operational challenges at McArthur River/Cigar Lake or front-loaded spending for future capacity, but either way near-term capital efficiency is deteriorating.
- Uranium EBT growth decelerated sharply from 48.8% to just 5.6% YoY despite continued price increases, signaling that cost inflation in mining operations is now absorbing most of the pricing benefit. The earnings growth engine in the core segment is stalling.
- WEC segment generated C$3.46B in revenue but only C$53.8M in EBT, a 1.6% pre-tax margin. After losing C$279.5M in FY2024, the turnaround is marginal. Cameco paid a premium for Westinghouse and the return on that investment remains deeply inadequate.
- ROIC of 5.5% against a cost of capital likely near 8-9% for a commodity producer means Cameco is currently destroying economic value despite optically positive earnings. The 9.5x P/B premium requires a dramatic ROIC expansion that the data does not yet support.

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
- Energy Fuels owns the only conventional uranium mill in the U.S. (White Mesa Mill in Utah), creating a regulatory and permitting moat that would take competitors a decade and hundreds of millions to replicate.
- The company's rare earth element processing pivot at White Mesa gives it optionality beyond uranium. With U.S. government prioritizing domestic REE supply chains, Energy Fuels could capture DOE and DOD contract value.
- Uranium supply-demand fundamentals are structurally tight. Post-Fukushima mine closures, Russian supply uncertainty, and 60+ new reactor builds globally create a multi-year tailwind for U3O8 prices above incentive levels.
- Vertical integration from mine to mill to sales eliminates middleman margin compression. Few peers (Cameco being the main one) have this full-chain capability at scale in a Western jurisdiction.
- U.S. ban on Russian uranium imports (signed 2024) directly benefits domestic producers like Energy Fuels, as utilities must re-contract with Western suppliers over the next 3-5 years.
By the Numbers
- Net cash position of $186M with cash per share of $3.84 against a $24.42 stock price means 16% of market cap is liquid cash, providing a massive buffer for a pre-production mining company burning cash.
- Current ratio of 30.7x and quick ratio of 28.2x are extraordinary liquidity levels, meaning Energy Fuels can fund operations for years without external financing even at current burn rates.
- Revenue 3Y CAGR of 74% and EPS 5Y CAGR of 67% show the company is transitioning from exploration to revenue generation, with consensus estimates projecting revenue scaling from $162M to $951M over five years.
- Tangible book value per share of $3.00 vs. near-zero goodwill and intangibles (0.3% of assets) means the balance sheet is backed by real mineral assets, not acquisition-driven write-up risk.
- Analyst estimates show EPS flipping positive in Y2 at $0.19 and accelerating to $1.40 by Y5, implying a forward P/E of ~17x on Y5 earnings, which is cheap for a uranium producer entering a structural supply deficit.
Risk Factors
- SG&A at 98% of revenue is staggering. The company is spending nearly a dollar on overhead for every dollar of sales, which means revenue must scale dramatically before operating leverage kicks in.
- FCF margin of negative 131% and FCF-to-OCF ratio of 1.0 (meaning zero capex distinction) suggests reported OCF is deeply negative. The $24M unlevered FCF burn with only $66M trailing revenue is unsustainable without the cash cushion.
- Cash conversion cycle of 444 days, driven by 490 days of inventory, signals massive working capital tied up in stockpiled uranium and vanadium. If commodity prices drop, this inventory becomes a mark-to-market liability.
- Debt-to-equity near 1.0x with $676M total debt against negative EBITDA means the company cannot service this debt from operations. The negative OCF-to-debt ratio of -12.7% confirms cash is flowing out, not in.
- Revenue declined 15.6% YoY despite a rising uranium spot price environment, suggesting timing-dependent sales or contract roll-off issues rather than steady commercial throughput.

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 first ISR operation in the Athabasca Basin, dramatically lowering capex versus conventional mining.
- The 22.5% stake in the McClean Lake mill (operated by Orano) provides toll-milling infrastructure already built and permitted. This eliminates the need to build a standalone processing facility, removing a major execution risk that most uranium developers face.
- Uranium's structural supply deficit is deepening as utilities sign long-term contracts post-Fukushima restarts. Denison's position in Saskatchewan, the most mining-friendly jurisdiction globally, avoids the permitting and sovereign risk plaguing competitors in Africa and Central Asia.
- Denison's physical uranium holdings (purchased through the uranium spot market) provide direct commodity price exposure and act as a balance sheet hedge. This is a differentiated strategy among developers, giving optionality without production risk.
- The Athabasca Basin land package beyond Wheeler River includes multiple early-stage exploration targets. If uranium prices sustain above US$80/lb, these become material option value that the market assigns near-zero worth to today.
By the Numbers
- Cash per share of C$0.54 exceeds the stock price-implied book value of C$0.45, meaning the company holds more cash than its entire net asset base. Current ratio of 12.0x signals years of liquidity runway without needing external financing.
- Analyst revenue estimates show a massive inflection: from C$21M in Y1 to C$184M in Y3 and C$926M in Y5. EPS flips positive by Y3 at C$0.03, then rockets to C$0.46 by Y5, implying a forward P/E of ~11x on Y5 earnings.
- Tangible book value per share equals total book value (zero intangibles/goodwill), meaning the balance sheet is clean with no acquisition-driven impairment risk. Every dollar of book value is backed by real assets or cash.
- EPS growth 5Y CAGR of +49% reflects losses narrowing materially over time. Trailing EPS of -C$0.10 vs. Y1 estimate of -C$0.04 confirms the loss trajectory is compressing by ~60%, consistent with approaching production milestones.
- Momentum and performance grades of 8.3/10 and 8.4/10 respectively are the strongest scores in the profile, suggesting the uranium cycle thesis is being priced in ahead of production. This is unusual for a pre-revenue miner and reflects sector-wide re-rating.
Risk Factors
- SBC-to-revenue ratio of 99.7% is staggering. Stock-based compensation nearly equals total revenue, meaning management compensation alone is consuming the equivalent of the entire top line. Buyback yield of -0.02% confirms zero offset to this dilution.
- Interest coverage of 0.06x is essentially zero, meaning operating income cannot service debt at all. Combined with net debt/EBITDA of 15.2x and debt-to-equity of 1.49x, the C$599M total debt load is entirely dependent on future production cash flows that don't yet exist.
- FCF margin of -18.4% and OCF margin of -13.9% show cash burn is worsening, not improving. FCF growth YoY declined 68%, and the 3Y FCF CAGR of -54% confirms the burn rate is accelerating as development capex ramps.
- Revenue per share of C$0.005 against a C$5.01 share price means the stock trades at roughly 1,000x revenue per share. Even with Y3 revenue estimates of C$184M, the implied P/S would still be ~19x, which is extreme for a mining company.
- DSO of 385 days is wildly abnormal for a mining company. Receivables turnover of 0.95x means it takes over a year to collect. This likely reflects non-cash revenue recognition or related-party transactions at the McClean Lake mill, not genuine commercial sales velocity.

Competitive Edge
- The 2024 spinoff of South Bow (Liquids Pipelines) transforms TC Energy into a pure-play natural gas infrastructure company, directly aligned with the multi-decade LNG export buildout and gas-fired power generation growth across North America and Mexico.
- Over 95% of cash flows are underpinned by long-term, take-or-pay contracts or cost-of-service regulatory frameworks. This contractual structure insulates EBITDA from commodity price swings and provides rare earnings visibility for a company in the energy sector.
- The NGTL and Mainline systems in Canada face limited direct competition due to regulatory barriers and geographic lock-in. Shippers have no practical alternative for moving WCSB gas to eastern markets, creating durable toll-road economics.
- Southeast Gateway pipeline in Mexico, now operational, serves CFE (Mexico's state utility) under a 30-year contract. This is effectively sovereign-backed revenue with inflation escalators, adding a growth vector with minimal volumetric risk.
- TC Energy's C$7B+ secured capital program is focused on rate-base accretive projects within existing pipeline corridors, reducing permitting and execution risk versus greenfield builds. Brownfield expansions carry higher return certainty.
By the Numbers
- Mexico Natural Gas Pipelines EBITDA surged 36.6% YoY to C$1.37B on 66.7% revenue growth, with EBITDA margins near 94%, signaling the Southeast Gateway pipeline is now contributing high-margin contracted cash flows with minimal incremental opex.
- Capex is rolling off sharply: Mexico capex fell 76.6% YoY to C$522M (from C$2.23B), and Canadian capex dropped 57% in FY2024. Total capital intensity should decline meaningfully, converting EBITDA growth directly into free cash flow improvement over FY2025-2026.
- FCF grew 53.5% YoY despite still-elevated capex, and FCF margin of 13.5% should expand materially as the C$5.3B annual capex run-rate normalizes. OCF-to-debt ratio of 12.5% is low but improving directionally as the growth capex cycle peaks.
- Operating margin of 44.4% and gross margin of 50.2% are consistent with a regulated/contracted pipeline business. SG&A at just 5.8% of revenue reflects the inherent operating leverage of midstream infrastructure once assets are in service.
- US Natural Gas Pipelines delivered C$4.9B in EBITDA on C$7.1B revenue (69% margin), with Q4 showing 30.7% QoQ EBITDA acceleration. This segment alone generates more EBITDA than the entire enterprise's interest expense, providing a floor under debt serviceability.
Risk Factors
- Net debt-to-EBITDA at 6.1x is elevated even for a regulated pipeline. With interest coverage at only 3.3x, refinancing risk is real: a 100bps increase in average borrowing cost on C$60B of debt would consume roughly C$600M, or ~8% of EBITDA.
- Payout ratio of 103% of earnings means the dividend is not covered by net income. FCF-to-net-income conversion of only 50% further strains this: capex-to-OCF is 72%, so dividend sustainability depends entirely on continued access to capital markets.
- Current ratio of 0.63 and quick ratio of 0.30 signal persistent short-term liquidity tightness. With C$60B in total debt and cash ratio of just 1.7%, TC Energy is structurally dependent on rolling commercial paper and credit facilities.
- EPS growth reads as negative across all timeframes (1Y, 3Y, 5Y, 10Y all showing -100%), reflecting the Keystone/Liquids Pipelines impairments and spinoff of South Bow. Reported earnings are deeply distorted, making P/E-based valuation unreliable without normalization.
- Power & Energy Solutions EBITDA dropped 17% YoY to C$1.0B with segmented earnings down 29.9%. Revenue fell 11.4%. This segment is now shrinking on both lines, and quarterly trends show continued QoQ EBITDA erosion through the last three quarters.
Nuclear is one of those rare sectors where the thesis keeps getting stronger, not weaker, the longer you watch it play out. Every few months there’s another headline about a government reversing course on reactor policy or a tech company signing a power purchase agreement that would’ve been unthinkable five years ago. The demand side isn’t theoretical anymore. It’s showing up in real contracts and real capital commitments.
What I’d caution against is treating every name in this space as a proxy for the same bet. They’re not. A uranium miner with no production is a completely different animal than an integrated engineering firm or a regulated pipeline operator with nuclear-adjacent exposure. The correlation between these stocks during a sell-off will be a lot lower than people expect, and that’s actually a feature if you understand what you own.
I think this theme has legs measured in decades, not quarters. But the price you pay still matters. A great secular trend doesn’t bail you out of a bad entry point.
