NuScale Power (SMR): Reassessing Valuation After a Sharp Multi‑Month Share Price Slide

Simply Wall St

NuScale Power (SMR) has been on a rough slide, with the stock down about 27% this month and roughly 66% over the past 3 months, even as revenue growth remains strong.

See our latest analysis for NuScale Power.

The latest slide comes after a sharp run up in prior years, with NuScale still sitting on a solid three year total shareholder return despite the recent weak share price momentum and concerns about execution risk resurfacing.

If NuScale’s volatility has you rethinking your exposure to infrastructure names, this could be a good moment to explore aerospace and defense stocks for other long term growth stories.

With shares now trading well below consensus price targets despite rapid top line growth and heavy losses, is NuScale a misunderstood clean energy play at a steep discount, or is the market already pricing in all the future upside?

With NuScale Power last closing at $15.79 against a narrative fair value near $38, the gap hinges on aggressive growth and long term margin expansion.

With an NRC approved SMR technology and the commitment of over $2 billion towards its development and licensing, NuScale is uniquely positioned for immediate commercial deployment compared to competitors focused solely on demonstration plans. This potentially accelerates revenue growth once commercial operations commence.
