NuScale Power stock has had a steep reset over the past year, yet valuation checks still suggest the shares are not a clear bargain, with the broader market pricing pointing toward an expensive profile despite the weak performance.

  • Over the past 12 months, NuScale Power has declined 82.9%, which shows that investors have already repriced the stock heavily.
  • The company’s approved small modular reactor design and potential long term power purchase agreements can support future revenue expectations, while ongoing legal challenges may weigh on how much investors are willing to pay for that potential.
  • NuScale Power passes only 1 out of 6 valuation checks, so on the broader measures it currently leans expensive rather than clearly cheap.

The issue now is whether NuScale Power’s sharp share price fall has already accounted for these risks, or if the stock still carries too much valuation risk for the level of uncertainty.

Has NuScale Power Run Too Far on Book Value?

P/B is a useful cross check for NuScale Power because it anchors the valuation to the company’s equity base rather than near term earnings. NuScale Power currently trades at a P/B of 2.6x, compared with an Electrical industry average of about 2.3x. That puts the stock at a premium to the sector on this balance sheet metric.

For a company facing legal challenges and still working toward large scale commercial deployment, this premium indicates that investors are paying more than the sector norm for each dollar of book value. Despite the sharp share price fall highlighted in recent news, the P/B multiple still prices NuScale Power above the typical peer in its industry.

On the P/B multiple, NuScale Power stock appears overvalued relative to the wider Electrical sector.

The Bottom Line

For NuScale Power, traditional valuation checks suggest the stock still leans overvalued, even after a steep 1 year share price decline. The current premium to the Electrical sector on P/B means you are paying up for a business that still has key legal and execution questions to answer. The crux for investors is whether NuScale Power can convert its approved small modular reactor design and potential contracts into a scale of commercial deployment that eventually justifies paying above sector multiples.
