NuScale Power Stock, October 2026: SMR Sector Rally Meets a Pre-Revenue Commercial Test

NuScale Power (SMR) gained 8.3% to close at $5.71 on October 27, 2026, with no published report identifying a specific catalyst, even as Q2 2026 revenue fell to $75,000 and key milestones — from TVA talks to a challenged Romania project — remain unresolved.

NuScale Power (NYSE: SMR) closed at $5.71 on October 27, 2026, up 8.3% on the session, with no published report identifying a specific catalyst for the move. The gain is best read against the volatile October backdrop across the nuclear sector: sharp swings in both directions have characterized the group this month. Yahoo Finance reported that a Google 3.6-gigawatt reactor deal in the same month lifted NANO Nuclear Energy and Oklo roughly 8%, with NuScale gaining 7% alongside them. October also produced at least one episode of sharp sector-wide decline, as 24/7 Wall St. noted that uranium prices broke a 19-year record while NuScale and peers fell simultaneously — illustrating the fragility of a trade that runs on expectations rather than current earnings.

The commercial foundation beneath these price swings remains thin but is beginning to accumulate real data points. Second-quarter 2026 revenue fell to $75,000 — a 99% collapse that The Motley Fool and 24/7 Wall St. reported in August — for a company that one August analysis described as carrying a roughly $4 billion market capitalization against $10.7 million in sales. NuScale simultaneously launched a $750 million equity offering that unsurprisingly amplified dilution concerns. Yet the other side of that trade is equally concrete: The Motley Fool noted that the cash raise expanded NuScale's cash pile by approximately $900 million, materially extending its operational runway. Slicast's compilation of SEC XBRL filings shows FY2025 revenue at $31 million, against which capital expenditure of $508,000 represents a 2% intensity ratio — itself a 1,054.5% increase from the $44,000 deployed in FY2024 — accelerating further to $2 million in the quarter ending March 31, 2026, the largest single quarter across the 22-period dataset stretching back to 2020.

The pipeline of commercial engagements is real, if none yet binding. Multiple outlets including Yahoo Finance UK and AsatuNews reported that NuScale is in active discussions with the Tennessee Valley Authority over a proposed 8-gigawatt SMR deployment. The Globe and Mail reported ENTRA1 is supporting NuScale's push to supply nuclear power for AI data centers, while MarketScale covered ongoing dialogue with Nucor about integrating SMR capacity into industrial power planning. Most concretely, Energies Media reported in September 2026 that NuScale and MillenniTEK had produced the first safety-grade fuel pellets for an SMR design already certified by the U.S. Nuclear Regulatory Commission, moving a critical hardware component from engineering drawings into physical fabrication.

Execution risks are equally specific and should not be minimized. Romania's government published an audit in September 2026 challenging the structure and delivery framework of NuScale's Doicești data center project, as TechStock2 reported. The September earnings miss reinforced analyst skepticism about near-term commercial velocity; Quiver Quantitative flagged the tension between the miss and the company's ongoing partnership discussions, and The Motley Fool attributed a separate sharp decline that month to setbacks in commercializing SMR technology. Foreignpolicyjournal.com identified growing data center backlash as a headwind for both NuScale and Oklo, adding a regulatory and reputational dimension to what is already a demanding construction and licensing timeline. Foreignpolicyjournal.com also projected a 70.5% improvement in operating losses, a constructive signal in isolation, though the absolute base from which that improvement accrues reflects how early NuScale remains in the commercial cycle.

NuScale's capital expenditure trajectory, compiled by Slicast from SEC XBRL filings across 22 periods from 2020 through 2026, captures a company still in the design-and-license phase rather than the build phase. Despite the steep percentage acceleration — $44,000 in FY2024, $508,000 in FY2025, $2 million in Q1 2026 — NuScale ranks last among all eight power-sector peers in Slicast's coverage on both absolute capex and capex intensity, with Vistra (VST) leading on intensity and Constellation Energy (CEG) on absolute spend. The gap is structural: NuScale holds an NRC-approved design, a competitive moat few rivals can match, but deploying that advantage at scale requires a sustained capital commitment and counterparty contracts that have not yet materialized in binding form.

Three signals will determine whether October's 8.3% session reflects durable re-rating or continued sector noise. First, whether TVA talks produce a term sheet or framework agreement — a first binding commercial commitment would represent a qualitative step change for a company that has operated almost entirely on potential. Second, the pace of additional NRC-certified hardware milestones following the fuel pellet announcement, as each validated component shortens the path to a construction permit application. Third, whether the operating loss trajectory visibly tracks toward the 70.5% improvement target: the $900 million cash cushion buys meaningful time, but the clock is running, and NuScale's history includes at least one prior project cancellation that reset the commercial calendar sharply. The NRC design certification is a genuine and rare asset; the outstanding question is whether NuScale can convert it into contracted revenue before the next capital raise becomes necessary.
