On September 29, Jim Cramer addressed the recent volatility surrounding defense and commercial nuclear equipment maker BWX Technologies, Inc. (NYSE:BWXT) during Mad Money. He said:
Here’s a bit of a puzzle. What the heck happened to the stock of BWX Technologies? Defense contractor, nuclear energy play, makes the reactors powering our submarines and aircraft carriers. After a huge multi-year run, the stock’s been clobbered. It’s down 27% over the past three months, in part because the latest quarter came in somewhat weaker than expected when they reported on August 3rd. Although I could say it’s really one or two lines. All the rest were good. Today, though, the company held a very good analyst meeting, laid out some really bullish long-term targets for 2030.
Cramer recently put BWXT head-to-head with Cameco—and picked a winner. Read more to find out which stock he favors.
Operational Scale and Strategic Moat in Nuclear Infrastructure
BWX Technologies, Inc. holds a virtual monopoly in manufacturing naval nuclear reactors and fuel components for the U.S. Navy, providing a sovereign defense moat that anchors the company’s long-term operational stability. The company manufactures the primary propulsion systems for Virginia-class attack submarines, Columbia-class ballistic missile submarines, and Gerald R. Ford-class aircraft carriers. At its September 29 Investor Day, management highlighted how this core defense anchor is converting into unprecedented operational visibility, with total backlog doubling to $8.4 billion, representing roughly nine quarters of contracted run rate. For 2026, BWXT projects full-year revenue of $3.8 billion, with approximately $3.7 billion, or 98%, generated directly from core nuclear activities.
To capture accelerating global demand across defense recapitalization and commercial nuclear power, the company is sharpening its operational focus by selling a majority stake in its non-core medical isotope unit for up to $800 million while retaining a 20% interest. Proceeds are being reallocated into high-return nuclear manufacturing assets, including a 500,000-square-foot footprint expansion through the Precision Components Group acquisition.
Supported by these investments, BWX Technologies, Inc.’s updated 2030 financial roadmap targets annual revenues of $5.5 billion to $6 billion on low double-digit compound organic growth, with adjusted EBITDA margins expanding from 17.5% to approximately 20% and cumulative free cash flow generation exceeding $2 billion through the end of the decade.

Valuation Multiples, Segment Performance, and Downside Risks
While BWX Technologies, Inc. delivered solid profitability in its second-quarter results, reporting non-GAAP diluted earnings per share of $1.07 on 18% revenue growth to $901.6 million, the market’s subsequent reaction highlights the fragility of its growth premium. The stock has endured a severe pullback from its 52-week highs of over $241 down into the $130-$140 range, driven by a broader industrial selloff. Even after the valuation reset, BWXT continues to trade at around a 36x TTM price-to-earnings multiple and 27x forward earnings. At that valuation, the market is pricing in strong execution of the commercial nuclear power supercycle, leaving little margin for error.
The primary bear case revolves around three distinct headwinds. First, the margin volatility within Government Operations cannot be dismissed as a temporary accounting anomaly, as it remains a constant, structural reality of defense contracting that frequently limits upside surprises. Second, while management’s 2030 model targets EBITDA margin expansion to 20% from 17.5%, realizing those gains depends heavily on scaling unproven commercial SMR production lines while navigating ongoing supply chain bottlenecks for military-grade specialty alloys. Finally, compounding these valuation concerns is insider selling has continued, including share sales by CEO Rex Geveden under a Rule 10b5-1 trading plan.

Smart Money Positioning and Bearish Sentiment
According to Insider Monkey’s data tracking over 1000 hedge funds, hedge fund holders expanded to 65 in the second quarter, compared to 61 in the preceding quarter. With 2.02 million shares, Alkeon Capital Management was the top hedge fund holder in Q2 as per Insider Monkey. Short interest remains low, with short interest at 4.42% of the public float.
As Cramer highlighted, the recent market pullback represents a temporary dislocation rather than a structural flaw in a business model supported by an irreplaceable naval nuclear monopoly and accelerating commercial clean-energy demand. By successfully balancing sovereign defense obligations with high-margin nuclear infrastructure expansion, BWX Technologies, Inc. offers investors a resilient long-term compounder capable of weathering near-term valuation compression and delivering durable multi-year returns.
