Nuclear Stocks Face-Off: CCJ vs BWXT vs CEG vs LEU in 6 Rounds

Four Stocks, Six Rounds, One Champion

The previous piece laid out the structural case that nuclear is the real bottleneck of the AI era. This one puts four candidates for that bottleneck head-to-head in numbers.

The contenders:

• Cameco (CCJ) — The uranium giant effectively controlling the fuel supply chain of the U.S. nuclear fleet
• BWX Technologies (BWXT) — A specialist expanding from naval reactors into commercial microreactors
• Constellation Energy (CEG) — The merchant generator hyperscalers call directly, bypassing the grid
• Centrus Energy (LEU) — The only U.S. company capable of producing HALEU

Rules are simple. Six rounds. Three points for first, two for second, one for third. Highest total wins.

The Six Rounds

Round	Metric	1st	2nd	3rd	4th
1	Net Profit Margin	LEU 17.3%	CCJ 16.9%	BWXT 10.3%	CEG 9.1%
2	Revenue Growth Forecast	CEG 28.8%	BWXT 17.4%	LEU 1.8%	CCJ -1.7%
3	CROIC	CCJ 13.8%	BWXT 10.9%	CEG 5.4%	LEU 2.3%
4	Levered FCF Margin	CCJ 30.9%	BWXT 9.2%	LEU 7.0%	CEG 5.0%
5	Profit-Adjusted PE (lower better)	LEU 2.87	CEG 2.96	BWXT 4.54	CCJ 6.51
6	Debt-to-Equity (lower better)	CCJ 14.7%	CEG 63.9%	LEU 159%	BWXT 167.1%

Final Score

• Cameco (CCJ): 11 points — Champion
• Centrus Energy (LEU): 9 points
• BWX Technologies (BWXT): 8 points
• Constellation Energy (CEG): 8 points

Round-by-Round Reading

Net profit margin — LEU leading at 17.3% is the round I find most surprising. The pricing power of a sole HALEU supplier is showing up in the actual numbers.

Revenue growth — CEG's 28.8% dominates. The market is pricing hyperscaler PPA expectations directly into guidance. CCJ being the only negative print at -1.7% reflects where it sits in the cycle.

CROIC and FCF margin — CCJ takes both capital efficiency rounds. The levered FCF margin of 30.9% versus BWXT's 9.2% shows how much of a cash machine Cameco becomes when uranium pricing is favorable.

Valuation — LEU and CEG cluster in the high-2x range on profit-adjusted PE. CCJ at 6.51 is the champion, but you're paying a premium for that quality.

Debt-to-equity — This is where the field splits. CCJ at 14.7% is effectively unlevered. BWXT at 167.1% and LEU at 159% are carrying a load that's hard to justify across a 7-10 year project cycle.

Positioning Summary

The scorecard tells you who's the most balanced allocation. It does not tell you who rallies fastest next quarter.

• CCJ — Stability and cash flow dominance. Growth momentum is weak.
• LEU — Margins and valuation are attractive, but debt risk is real. The high-risk bet on domestic fuel independence.
• BWXT — A record $7.3B backlog gives the best visibility, but the balance sheet is heavy.
• CEG — Growth leader and the purest play on direct hyperscaler contracts. Lower capital efficiency.

My Take

CCJ winning overall is because it placed first or second in four of six rounds. The combination of 14.7% debt-to-equity and 30.9% FCF margin is the financial profile best built to survive a 7-year project cycle.

That doesn't mean 'only buy CCJ.' CEG is the most direct growth exposure, LEU is the biggest valuation discount, and BWXT has the cleanest backlog visibility. Which one fits your portfolio depends on your risk tolerance and time horizon.
