Why Smart Investors Are Skipping Popular SMR Stocks for This Hidden Nuclear Play

When it comes to nuclear energy stocks, 2025 has been dominated by talk of small modular reactors—with NuScale Power, Nano Nuclear Energy, and Oklo capturing investor imagination. But here’s what most investors miss: the real opportunity in nuclear might not be with these trendy startups at all. Instead, it lies with an unglamorous engineering company that’s already profitable and deeply embedded in the nuclear supply chain.

The small modular reactors stocks have delivered impressive gains early in the year, partly fueled by the Trump administration’s May executive orders promoting nuclear energy and partly by the urgent power demands of expanding artificial intelligence data centers. Yet beneath the surface, these same stocks have become increasingly problematic investments—and for a simple reason: they’re far from generating profits.

The SMR Bubble: Growth Without Earnings

All three leading small modular reactors companies share a critical weakness: minimal or nonexistent revenue streams. NuScale Power generates less than $64 million in annual revenue, while Nano Nuclear Energy and Oklo have no meaningful revenue at all. More troublingly, analysts don’t expect any of these small modular reactors stocks to reach profitability before 2030 at the earliest.

The market has begun pricing in this reality. Since hitting peaks in mid-October, the stocks have faced brutal sell-offs: Nano Nuclear Energy down 46%, Oklo down 48%, and NuScale Power down a crushing 62%. These declines reflect growing investor skepticism about both the near-term viability of small modular reactors technology and the timeline for return on investment.

The Established Builder With Nuclear Exposure

Enter Fluor Corporation, a $6.6 billion engineering and construction firm that represents a fundamentally different approach to nuclear exposure. Unlike the speculative small modular reactors stocks, Fluor is profitable today—reporting $3.4 billion in earnings over the last twelve months. More importantly, the company operates in a proven, high-revenue business: constructing full-scale nuclear power plants.

What makes this particularly intriguing is Fluor’s 38.9% ownership stake in NuScale Power. At NuScale’s current valuation of $6 billion, Fluor’s stake alone is worth approximately $2.3 billion—representing over one-third of Fluor’s entire market capitalization. This means you’re essentially getting Fluor’s real business—its engineering and construction operations—almost for free.

The Valuation Picture

When you account for Fluor’s NuScale holding plus its $1.8 billion cash advantage over debt, these two factors alone back approximately 62% of Fluor’s $6.6 billion market cap. This leaves an enterprise value of just $2.5 billion for the actual operating business.

Against that $2.5 billion enterprise value, Fluor generated $360 million in real operating profit, analysts estimate for the coming year, with expectations for 36% growth over the next three years. At these figures, Fluor trades at an enterprise-value-to-earnings multiple of less than 7—a valuation that looks remarkably attractive relative to the company’s expected growth trajectory.

Japan’s $550 Billion Bet: A Game-Changer for Large Nuclear

Here’s where the narrative shifts dramatically. In a development that received minimal mainstream attention, the U.S. Department of Energy recently announced that Japan is committing $550 billion in direct U.S. investment—with $80 billion specifically earmarked for constructing 10 large-scale nuclear power plants. These are precisely the type of major nuclear facilities that Fluor has spent decades building.

This announcement is potentially transformative. While small modular reactors stocks may struggle to find the capital and regulatory pathways for deployment, established nuclear builders like Fluor face a multi-billion-dollar opportunity in Japan-backed, large-scale projects. The geopolitical angle—involving tariff negotiations and strategic energy partnerships—adds credibility to this infrastructure spending.

A More Rational Path to Nuclear Exposure

Investors drawn to nuclear energy for legitimate reasons—AI power demands, decarbonization trends, energy security—face a choice. They can chase speculative small modular reactors stocks with uncertain timelines and no near-term profits. Or they can own Fluor: a profitable, established player with direct exposure to both SMR upside through its NuScale stake and enormous potential from next-generation large reactor projects.

For a $1,000 or $2,000 investment, Fluor presents a more defensible risk-reward proposition. You’re not betting on technology that may or may not scale, or on companies that need years to achieve profitability. You’re owning a profitable business trading at reasonable multiples, with meaningful nuclear optionality baked in.

The nuclear thesis remains compelling. The question isn’t whether nuclear will matter—it clearly will. The question is whether you’d rather own the reactor developers or the people who actually build them. Based on current valuations and time horizons, the answer seems straightforward.
