NuScale revenue fell to $75,000 in the second quarter of 2026, down from $8.054 million a year earlier, while the net loss widened to $50.063 million from $37.609 million. Those figures, reported on 5 August 2026, sit against $1.9 billion in cash and investments. The result turns NuScale from an operating story into a question of how long a balance sheet can carry a reactor design that has yet to sign a definitive power purchase agreement.
NuScale revenue tracks engineering milestones, not demand
The company attributes the revenue decline mainly to Fluor’s front end engineering and design work, FEED Phase 2, on the RoPower project in Romania, which was completed in late 2025. The quarterly drop of $7.98 million is 99.1 percent of the prior year figure. Over six months, revenue was $640,000 against $21.429 million, a fall of 97.0 percent. The percentages are calculated from the reported figures.
That pattern is the core weakness in the current NuScale revenue line. Income arrives in lumps when a project passes through a paid engineering phase and disappears when the phase ends. Without a project in construction or a licensing fee schedule, there is nothing to replace it.
Losses grow as revenue shrinks
The net loss rose 33.1 percent year on year. The loss attributable to Class A common stockholders was $47.539 million against $17.641 million, about 2.7 times higher. For the half year, the net loss reached $96.748 million versus $68.004 million.
The company lists the drivers: research and development expenses up $6.6 million, general and administrative expenses up $4.4 million and other expenses up $8.0 million, partly offset by $8.5 million more investment income and $6.0 million lower cost of sales. Spending is rising on the development side while the revenue that funded it has gone.
A balance sheet doing the work of a revenue line
Cash, short term investments and long term investments totalled about $1.893 billion at 30 June 2026, compared with about $1.287 billion at 31 December 2025, according to the company’s filing with the US Securities and Exchange Commission. Cash rose by roughly $606 million in six months in which the net loss was $96.7 million, which implies financing inflows rather than operating cash generation. The release excerpt does not detail them.
At the first half pace, the annualised net loss is about $193 million, so $1.9 billion would cover roughly ten years of losses. That is arithmetic, not a forecast: net loss is not cash burn, and spending could rise sharply if a project reaches construction.
The two agreements that decide the next NuScale revenue
ENTRA1 Energy, NuScale’s exclusive global strategic partner, continues to advance discussions with the Tennessee Valley Authority toward a definitive power purchase agreement. The company gives no signing date. In Romania, NuScale is working with Nuclearelectrica and RoPower to satisfy conditions attached to the Nuclearelectrica shareholder vote for a plan to deploy six NuScale Power Modules at a former coal plant site in Doicești. No deadline for meeting the conditions is given.
The structural problem is that framework agreements generate headlines but not revenue. The solution the company is pursuing is conversion into definitive contracts and a construction decision. Until one of the two arrives, NuScale revenue will keep following paid engineering phases, as it has since 2025. Other developers are spreading their bets across designs, as in ABB’s nuclear SMR deal, one of several bets on competing reactors.
