Why Fluor May Be The Best Nuclear Stock Pick Over Other SMR Plays In 2026

The nuclear energy sector has captured investor imagination throughout 2025 and into 2026, particularly around small modular reactor (SMR) technology. Companies like Nano Nuclear Energy (NASDAQ: NNE), NuScale Power Corporation (NYSE: SMR), and Oklo (NYSE: OKLO) have all seen explosive growth as policy tailwinds and artificial intelligence’s voracious appetite for power drive a sector-wide rally. Yet a closer look at the actual best SMR stocks reveals an uncomfortable truth: the obvious choices may not be the smartest choices.

The SMR Trap: Momentum Without Margins

All three of the leading small modular reactor companies have indeed climbed substantially year to date, buoyed by President Trump’s May executive orders promoting American nuclear technology and the recognition that AI data centers will require enormous amounts of electricity to function. The investment thesis seems irresistible: the future of energy is here, and these companies will build it.

But momentum investors who chased these stocks have recently faced harsh corrections. Over the past six months, Nano Nuclear surrendered nearly half its value, declining roughly 46%. Oklo fared similarly with a 48% pullback. Most severe was NuScale Power, which cratered 62% from its mid-year highs. These weren’t mere profit-taking cycles—they reflected a fundamental reality that had finally registered with the market: none of these companies actually makes money.

Consider the revenue picture. Of the three SMR leaders, only NuScale generates meaningful revenue at roughly $64 million annually. Nano Nuclear and Oklo remain entirely revenueless. More critically, analyst consensus from S&P Global Market Intelligence suggests none of these companies will achieve profitability before 2030 at the earliest. That’s a minimum of four to five years of cash burn ahead, regardless of the favorable regulatory environment.

The Overlooked Alternative: A Nuclear Builder With Actual Profits

This is where the case for best SMR stocks takes an unexpected turn. Rather than betting on tomorrow’s winners, what if investors considered today’s proven operator? Fluor Corporation (NYSE: FLR) is an engineering and construction giant that builds large-scale nuclear power plants generating 1 gigawatt or more of electricity. It’s also the majority shareholder of NuScale, holding a 38.9% stake.

That ownership position alone tells an interesting story. At NuScale’s current implied market value of approximately $6 billion, Fluor’s stake represents roughly $2.3 billion in value—more than one-third of Fluor’s entire $6.6 billion market capitalization. Beyond this, Fluor maintains a net cash position of $1.8 billion after accounting for debt. Combined, these two assets underpin 62% of the company’s market value, implying an enterprise value of just $2.5 billion for the profitable, cash-generating business.

The Valuation: A Bargain That Defies Logic

For that $2.5 billion enterprise value, investors are acquiring a company that reported $3.4 billion in earnings over the trailing twelve months. However, a meaningful portion of those profits came from accounting gains tied to NuScale’s valuation swings—gains that evaporate as the subsidiary’s stock declines.

Strip away those non-cash items, and analyst expectations suggest Fluor will generate approximately $360 million in genuine operating profit next year, growing roughly 36% annually over the subsequent three years. This implies a 12% compound earnings growth rate. Priced at an enterprise-value-to-earnings multiple below 7 times, Fluor appears aggressively undervalued relative to growth expectations.

For perspective, this valuation screams “opportunity” compared to speculative SMR plays commanding premium valuations while remaining unprofitable. A modest $2,000 investment at current prices could represent meaningful exposure to a company already generating cash rather than perpetually consuming it.

Japan’s $80 Billion Wager: A Catalyst Beyond SMR

A development that largely escaped mainstream attention just weeks ago underscores Fluor’s strategic positioning. The U.S. Department of Energy announced that Japan—as part of a broader $550 billion investment commitment to America in exchange for tariff relief—will commit $80 billion specifically toward constructing ten large-scale nuclear power plants. These are precisely the kind of flagship reactors that Fluor specializes in building.

For shareholders obsessed with best SMR stocks, this might seem like a sideshow. For Fluor investors, it represents genuine revenue visibility. While SMR companies remain locked in development and regulatory approval stages, Fluor already possesses the operational track record and expertise to execute billion-dollar nuclear construction contracts. Japan’s capital deployment could translate into years of substantial revenue and profit contributions.

Making The Investment Case: Risk and Reward

Does owning Fluor stock guarantee success? Absolutely not. The nuclear sector remains subject to regulatory shifts, construction delays, and political changes. Additionally, Fluor’s substantial stake in the struggling NuScale could deteriorate further if the SMR company faces additional setbacks.

Yet relative to the choices among SMR stocks available today, Fluor offers a compelling risk-reward asymmetry. It generates real profits, trades at an undemanding multiple, controls a major ownership stake in a promising SMR pioneer, and now stands positioned to capitalize on concrete infrastructure contracts visible for years ahead. For the conservative investor seeking exposure to nuclear energy’s growth without speculative binary risk, Fluor deserves consideration as among the best-positioned nuclear plays entering 2026.

An allocation of $1,000 to $2,000 in Fluor stock today represents a materially different investment proposition than chasing the volatility of unprofitable SMR companies—one centered on tangible earnings rather than speculative potential.
