- NuScale ended regular trading June 18 at $11.74, rising 13.54% on the day, then eased to $11.67 in the after-hours session. U.S. markets did not trade June 19 for Juneteenth.
- Paragon landed the final design contract for systems linked to NuScale’s small modular reactor project, a new marker for investors watching execution.
- Execution and cash burn are still issues. First-quarter revenue fell to $565,000 from $13.4 million last year.
NuScale Power Corp was last at $11.74 in regular trading Thursday, holding most of a sharp rally in a holiday-shortened week. The NYSE-listed nuclear stock surged about 19% from a week earlier, but markets were closed Friday for Juneteenth and through the weekend.
Timing could be key. Investors will get their first full shot at this stock on Monday after a volatile rally last week. The New York Stock Exchange’s regular hours are 9:30 a.m. to 4:00 p.m. ET. The exchange lists Juneteenth National Independence Day as a market holiday on Friday, June 19, 2026.
NuScale’s most recent news was more about getting things done. The company announced on June 17 that Paragon, part of Mirion Technologies, got a contract for the final design phase on protection, display and control-room systems for the NuScale Power Module. NuScale CEO John Hopkins said Paragon’s systems are “essential to safe and reliable plant operations.” Paragon CEO Doug VanTassell called it “foundational” to bringing the reactor online.

Small modular reactors, called SMRs, are nuclear reactors built as smaller units than regular plants. They’re usually made in factories, then installed at sites. NuScale uses SMR as its ticker, so the name looks tidy on the board. That can blur things for investors: this is a long-horizon industrial bet, not a fast-moving power play.
NuScale is pushing its first-mover angle. In May, the company said ENTRA1, its strategic partner, kept working with the Tennessee Valley Authority to plan up to 6 gigawatts of NuScale SMR capacity. NuScale closed out the first quarter with $1 billion in liquidity and capital resources. Hopkins at the time said demand for “reliable, carbon-free power” had never been higher. NuScale Power
Market mood was better as the broader indexes posted gains. U.S. stocks ended higher Thursday, with the S&P 500 adding 1.1%, the Nasdaq Composite gaining 1.9%, and the Russell 2000 up 2.1%, AP reported. That move helped speculative and small-cap stocks ahead of the long weekend.
Vattenfall in Sweden went with Rolls-Royce SMR for its new nuclear project last week, dropping GE Vernova. Utility-scale SMR wins are still political and competitive. CEO Anna Borg said, “This project will now be turned into reality.” Reuters
NuScale keeps trading more on potential than on progress. Investors mostly react to each new supply-chain or design update as another step toward real deployment. But the stock doesn’t trade like a typical utility—shares move more like a bet on future nuclear contracts, new data center demand, and government support.
NuScale spelled out the risks in its March quarter filing, calling out “significant risks and uncertainties” tied to its funding needs before commercialization and winning customers. The company burned through $314.7 million in operating cash for the quarter. If customer deals don’t come through, project spending goes higher, or more equity sales pressure the stock, last week’s jump could reverse fast. SEC
Looking to this week, NuScale faces a price test at $11 to $12 after big volume Thursday. But the main question is whether the company can convert its design, new partnerships and regulatory edge into real orders that move revenue.
