NuScale Power (SMR) Stock Could Be Undervalued Despite Legal Uncertainty

Simply Wall St · 20h ago

NuScale Power has seen its share price move sharply in recent years, and after a steep pullback the puzzle for investors is whether the current US$4.66 level lines up with what the company’s book value can reasonably support. With fresh legal and commercial headlines in play, the question now is how much of the balance sheet story is already reflected in the stock.

  • Over the past 3 years, NuScale Power has delivered a share price gain of 86.4%. This puts real weight on whether the balance sheet can underpin that kind of long run move.
  • A class action over alleged misstatements around competitive edge, revenue potential and cash runway, together with a key but still uncertain agreement with the Tennessee Valley Authority, can influence how much value investors are comfortable assigning to NuScale Power’s equity relative to its recorded net assets.

The stock’s next move may depend on whether NuScale Power’s current market value lines up with, or departs from, what its book value might justify.

Is NuScale Power Still Cheap on Book Value?

For a business like NuScale Power that is still working toward commercial scale, investors often focus on price to book because it anchors the share price to the net assets already recorded on the balance sheet.

On this lens, NuScale Power trades on a P/B of about 0.9x, compared with an Electrical industry average near 1.8x and a peer group closer to 4.9x. That means the market is valuing the equity at a discount to both the sector and to similar companies, even though book value reflects assets that are already in place rather than hoped for future projects. The recent class action lawsuit over alleged misstatements around competitive advantage and cash runway helps explain why investors might be hesitant, because legal and execution risks can keep a lid on how much of that asset base the market is willing to pay for.

For anyone weighing whether this discount signals opportunity or just higher risk, it is worth lining up the P/B against NuScale Power’s cash burn, contract visibility and regulatory milestones. Explore the numbers behind NuScale Power's P/B valuation.
