NuScale Power (SMR), September 2026: Romania Audit and Earnings Miss Test the Nuclear Build-Out Case

NuScale Power fell 8.5% to $8.27 on September 18 with no published report identifying the specific catalyst, as a Romanian government audit challenging the Doicesti project structure and a below-consensus earnings result mark the most concrete near-term headwinds for a development-stage company whose valuation runs well ahead of its commercial revenues.

NuScale Power (NYSE: SMR) closed at $8.27 on the September 18 session, a decline of 8.5%, leaving the stock below $10. No published report has identified a specific catalyst for that session's move. What the coverage does show is a company at an inflection point: its NRC-approved SMR design has moved closer to hardware fabrication, large-scale utility talks are ongoing, and yet a Romanian government audit has surfaced structural questions about a flagship international project while the most recent earnings result came in below analyst expectations.

The financial picture remains that of a pre-revenue development-stage enterprise. Second-quarter revenue fell to $75,000 — a 99% year-on-year decline — while cash reserves grew by approximately $900 million, sustained in part by a $750 million at-the-market equity facility. The August 2026 prospectus supplement filed with the SEC under a 424B5 names UBS Securities, B. Riley Securities, Canaccord Genuity, Craig-Hallum Capital Group, Texas Capital Securities, and Tuohy Brothers as selling agents under that arrangement. Fiscal-year 2025 capital expenditure reached $508,000 — up 1,054.5% from $44,000 in FY2024 — but still represents just 2% of NuScale's $31 million FY2025 revenue base. In Slicast's capex dataset for the power sector, NuScale ranks last by absolute spending (eighth of eight) and last by capex intensity (seventh of seven), a profile consistent with a technology licensor building toward deployment rather than an operating generator.

The operational pipeline moved forward on at least one front. In September 2026, NuScale and MillenniTEK produced the first safety-grade fuel pellets for an SMR design already cleared by the Nuclear Regulatory Commission, moving a key hardware component from drawing board to fabrication. Utility talks have also continued at scale: coverage from August and September reports NuScale in discussions with the Tennessee Valley Authority over a potential deployment that the company's chief executive has characterized as the largest nuclear buildout in U.S. history, with estimates suggesting a capacity range of 6 to 8 gigawatts. Separate September coverage describes conversations between NuScale and Nucor over integrating SMR capacity into industrial power planning, while European data-center operators have been reported exploring SMR supply from both NuScale and Oklo to meet surging load. A strategic alliance with Nuclearn and NPX to deploy nuclear-specific AI tools, announced in August, rounds out a pipeline spanning hardware fabrication, utility contracting, and operational technology.

The Romania development introduces a different category of risk. A Romanian government audit released in September 2026 challenged the structure and delivery model of NuScale's Doicesti nuclear power and data-center project. Coverage notes the audit questioned project structure and delivery approach but does not specify required remediation or a government response timeline. The significance is less the audit itself than its precedential value: international SMR projects are now subject to host-government scrutiny rigorous enough to produce formal audit findings, and the Doicesti case — whatever its outcome — will be closely read by other jurisdictions considering analogous arrangements.

The valuation debate runs through most of the September 2026 commentary on the stock. Coverage reports NuScale projecting a 70.5% improvement in operating losses, which would meaningfully narrow the burn rate even as commercial revenues remain minimal. Multiple outlets describe the stock as a binary proposition: either a first signed commercial order — most plausibly a TVA agreement — validates the development investment and reframes the price, or the persistent gap between announced partnerships and funded, executing contracts continues to weigh on a valuation that runs well ahead of current revenues.

Three near-term signals will do the most to resolve that binary. First, the TVA negotiation outcome: any signed agreement, even for a fraction of the reported 6 to 8 gigawatts, would mark NuScale's first large-scale commercial order and reset the debate about delivery timelines. Second, Romania's formal response to the Doicesti audit — whether it constrains, modifies, or clears the project — will set a governance precedent for SMR deployments in Europe. Third, the drawdown rate on the $750 million equity facility: the pace at which management taps that instrument will signal how much cash runway the company believes it has and, implicitly, how near or distant the moment of first construction revenue actually is.
