NuScale Power Soared 40% This Week, but Fundamental Risks Remain

英伟达的AI霸主之路:2030年市值10万亿美元的底气何在?

As of the close on April 17, 2026, U.S. small modular reactor (SMR) leader NuScale Power (NYSE: SMR) spiked as much as 44.4% intraweek and closed near $12.65, posting impressive weekly gains. A double dose of positive policy developments ignited a risk-on sentiment recovery in the nuclear energy sector.

Twin Policy Catalysts Usher in a “Nuclear Week” for the SMR Sector

The nuclear rally this week originated from policy signals released by the U.S. and the U.K. on the same day. On April 14, the White House unveiled the National Initiative for American Space Nuclear Power, a national program led jointly by NASA and the Department of Defense with hard deployment timelines: nuclear reactors in orbit by 2028, a mid‑power reactor on the Moon by 2030, in‑space reactors around 2031, and scalable high‑power reactors in the 2030s. On the same day, the U.K. government announced £599 million (approximately $800 million) in funding for Rolls‑Royce’s SMR program, with plans to build a three‑unit SMR project at the Wylfa site in Wales. The project is expected to deliver about 1.4 GW of electricity, covering the energy needs of around three million households for up to 60 years. Lifted by these developments, nuclear‑related stocks rallied across the board: NuScale jumped about 7% in a single day, and Oklo surged 8.6%.

Fundamental Risks Beneath the Stunning Gains

However, NuScale’s fundamentals have not changed overnight because of the policy tailwinds. The company remains in a prolonged and painful pre‑commercialisation phase, with its first plant not expected to become operational until 2030 at the earliest – at least four years away. For the full year 2025, revenue was just $31.5 million, down about 15% year‑on‑year, while the net loss widened to $664.5 million.

More concerning, the company’s relationship with its exclusive commercialisation partner, ENTRA1 Energy, is now facing a class‑action lawsuit. Plaintiffs allege that NuScale misled investors about the partner’s qualifications – claiming that ENTRA1 has never actually owned, financed, or operated any nuclear energy project.

In November 2025, after making a milestone payment of approximately $495 million to ENTRA1, the company’s quarterly net loss soared to $532 million, and the stock tumbled more than 12% in two days. Meanwhile, major shareholder Fluor recently reduced its stake by about 12.94 million shares – nearly 49% of its holdings – cashing out approximately $150 million. Insiders have sold a cumulative 27.07 million shares over the past 90 days.

Wall Street Divergence: Can Policy Tailwinds Survive the Commercialisation Fog

Analysts have a consensus rating of “Hold” on NuScale. Among the 12 analysts covering the stock, only 25% have a “Strong Buy” recommendation, while 42% suggest “Hold.” RBC analyst Chris Dendrinos maintains a “Sector Perform” rating with a $14 price target, arguing that while the company is making incremental progress in the right direction, the path from the current stage to a final investment decision is long, and any delays would increase equity dilution risk. On the bullish side, proponents highlight NuScale’s unique moat: it remains the only advanced reactor company with a standard design certification from the U.S. Nuclear Regulatory Commission (NRC). The global SMR market is expected to grow from $8.1 billion in 2026 to $17.3 billion by 2035, giving NuScale a significant first‑mover advantage.

Investment Implications: A Tug‑of‑War Between Long‑Term Narrative and Short‑Term Realities

NuScale’s investment thesis is essentially a battle between the long‑term narrative – incremental electricity demand from AI data centres plus global decarbonisation policies – and the short‑term reality of a pre‑profit business, partner controversy, and sustained insider selling. For investors willing to hold for five years or longer, if SMR technology scales as expected, NuScale’s current market capitalisation of less than $4 billion could offer substantial return potential. However, for those unable to stomach high volatility and a long wait, chasing the stock after this week’s sharp rally carries significant risks that should not be underestimated.
