The investment thesis on NuScale Power is that its decade-long head start in the nuclear regulatory process creates a wide wall that competitors cannot quickly climb, making it the only viable choice for tech giants needing carbon-free power for AI data centers. NuScale is the only company with a certified small modular reactor design in the U.S., allowing it to move toward manufacturing while rivals are still filing paperwork. If it can successfully convert its pipeline into operating plants without further project cancellations, it owns the "baseload" power market of the future.
NuScale stock jumped early on but has crashed over the last year. The company spent a long time as a hot bet on new nuclear technology, but the price sank as people realized how much cash the business is burning to finish its reactor designs. It is now trading far below where it started.

What does it do?
NuScale Power is an early-stage business that earns money by designing, licensing, and selling small modular nuclear reactors (SMRs). The company does not build the plants itself; instead, it provides the proprietary "Voygr" power plant design and sells the actual NuScale Power Modules, which are the standardized reactors at the heart of the facility. Revenue flows from three main streams: initial engineering and licensing services, the sale of the physical reactor modules, and long-term service agreements once the plants are operational. By using a modular design, the company aims to make nuclear power cheaper and faster to build than traditional large-scale reactors.
Where does revenue come from?
The vast majority of current revenue comes from engineering and consulting services provided to project partners. While the ultimate goal is selling physical reactor modules, the company is currently in the "Front-End Engineering and Design" (FEED) stage for its major projects. Revenue is concentrated in these services, though it will eventually shift toward high-margin module sales and recurring maintenance fees once plants are commissioned.
Who are its customers?
NuScale Power serves large utility companies, sovereign nations, and industrial partners who need massive amounts of carbon-free electricity. The company currently lists a total of five major project partners in varying stages of development, including RoPower in Romania and the Tennessee Valley Authority (TVA) in the United States. In its most recently reported nine-month period ending September 30, 2025, the company generated $29.7 million in total revenue, up from just $2.8 million in the prior year. This growth was driven primarily by engineering services for the RoPower project. Management is now aggressively targeting "hyperscale" data center operators who require 24/7 power that wind and solar cannot provide alone.
What gives it staying power?
NuScale’s staying power comes from being the first and only SMR designer to receive a Standard Design Approval from the U.S. Nuclear Regulatory Commission. This regulatory "moat" is incredibly difficult to replicate, as the approval process took nearly a decade and cost hundreds of millions of dollars.
Where is it headed?
The company is focused on becoming the primary power supplier for AI data centers through its exclusive partnership with ENTRA1 Advisors. Management believes the urgent need for carbon-free, always-on electricity for AI workloads creates a massive new market for their modular reactors. Success here would move NuScale from a government-subsidized research project to a high-volume manufacturing business.
The most important trend is the sharp acceleration in revenue, which jumped from $2.8 million to $29.7 million for the first nine months of fiscal 2025. This shift signals that NuScale is finally moving from pure research into the active engineering and design phase for commercial projects.
Cash quality is currently poor because the company is burning roughly $45 million to $70 million per quarter to fund its development. However, the business recently de-risked its runway by raising $475.2 million through an at-the-market share offering, bringing its total cash and investments to $753.8 million.
The balance sheet is exceptionally strong for an early-stage company, carrying zero debt and a massive cash cushion that should last several years. This liquidity is critical because it allows the company to continue its long-term regulatory and manufacturing work without the immediate threat of insolvency.
NuScale Power is a pre-profit technology company that has successfully traded equity for a multi-year cash runway, essentially buying the time it needs to reach commercial scale.
The company successfully raised $475.2 million in a single quarter, ending September 30, 2025, with $753.8 million in total cash and no debt. This massive capital infusion effectively ends the "going concern" risk that had previously hung over the stock. It provides management with the breathing room to focus on project execution rather than just survival.
The single most important risk is the high cost of nuclear power compared to other energy sources, which could lead to project cancellations. If customers decide that the "first-of-a-kind" costs are too high, the pipeline of orders could dry up before the company reaches manufacturing scale. Management has yet to prove they can deliver a completed plant at the prices they have promised.
The small modular reactor market is effectively zero today but is projected to exceed $150 billion by 2035 as countries race to decarbonize their power grids. The industry is shaped by a brutal regulatory barrier: it takes nearly a decade and billions of dollars to get a nuclear design approved for construction. NuScale is the clear first-mover in the United States, positioning it as the only viable "off-the-shelf" option for utility companies and data center operators who need to start building today.
The nuclear industry is characterized by high barriers and low price sensitivity for carbon-free power, but competition is intensifying as government subsidies attract new entrants. While many rivals exist, the market is currently a race to reach "commercial operation" rather than a fight for market share. One soft project launch could damage the credibility of the entire sector. Pricing power is currently high for whoever can actually deliver a working plant first.
TerraPower and X-energy are the most dangerous threats because they use "next-generation" cooling technologies that could eventually be more efficient than NuScale's traditional water-based system. GE Hitachi and Westinghouse are also formidable because they can leverage existing global supply chains and massive balance sheets to undercut NuScale on price. The most dangerous threat is the arrival of a "big nuclear" player that can manufacture reactors at a scale NuScale cannot match.
NuScale is currently holding its ground as the only company with a government-certified design, but it is under pressure to prove it can execute after its first major project in Utah was cancelled in 2023. The company is the clear leader in regulatory progress, which is the only metric that matters right now.
NuScale’s primary source of protection is its regulatory moat, specifically the Standard Design Approval it received from the U.S. Nuclear Regulatory Commission. This approval is a physical asset that rivals simply do not have; getting it required millions of pages of data and years of testing. The NRC certification is a decade-long wall that prevents any new competitor from entering the market quickly.
The company's financials do not yet reflect a wide moat because it is pre-profit, but the 22.4% gross margin on its early engineering services shows it can charge a premium for its expertise. The current metrics show a business that is trading its regulatory lead for early-stage consulting revenue.
The forward-looking verdict is that this moat is widening as NuScale moves closer to manufacturing while competitors are still stuck in the early licensing phase. The NRC certification is the most durable advantage in the energy sector today.
Cancelled Utah CFPP project in 2023, but grew revenue 10x in 2025.
Raised $475M via ATM when stock was high, de-risking the runway.
CEO John Hopkins has led the company since 2012, through the SPAC merger.
Capital Allocation Track Record
John Hopkins has shown exceptional judgment by raising nearly $500 million in cash when the stock price was high, effectively removing insolvency risk for the next several years. While the cancellation of the company's first major project in Utah was a significant blow to credibility, management has pivotally refocused on the high-growth data center market. Their ability to navigate the most rigorous regulatory environment in the world for over a decade suggests a level of strategic persistence that few executive teams possess.
The thesis is heavily dependent on the current leadership team's specialized knowledge of nuclear regulations, creating a moderate key-person risk. If John Hopkins or the senior engineering heads were to leave, the company’s relationship with the Nuclear Regulatory Commission and its project partners could fray. However, the company has built a deep bench of nuclear engineers and policy experts, and the majority ownership by Fluor Corporation provides a stable corporate foundation that mitigates typical start-up governance concerns.
The market is leaning bullish because NuScale is finally transitioning from theoretical designs to concrete engineering and design completion. Securing contracts like the one awarded to Paragon for final design work provides visible progress toward finishing the reactor models that customers actually need to buy and install.
Skeptics think that the actual path to building and selling these reactors remains blocked by massive financial and operational hurdles. Critics point to the Citigroup downgrade as evidence that the company still lacks the proven ability to deliver profitable, large-scale hardware deployments to the energy market.
