X Energy (XE) Stock Looks Overvalued Following Its 44% Slide

Simply Wall St·07/23/2026 06:29:34
Listen to the news

X-Energy has joined high profile nuclear headlines this year, but with the stock down 43.7% year to date and both its Discounted Cash Flow (DCF) intrinsic value estimate and market multiples pointing to a premium, the price now raises questions about how much of the story is already reflected in the share price.

  • The share price has fallen 43.7% year to date, which means investors are being asked to reassess what they are willing to pay for X-Energy's future cash flows.
  • Participation in U.S. initiatives to expand advanced nuclear capacity, including fuel work via TRISO-X, can support long term growth expectations, while execution, capital needs and project timing remain key risks to how quickly those expectations translate into cash generation.
  • On Simply Wall St's broader valuation checks, X-Energy scores 0 out of 6, which suggests the stock does not screen as a clear bargain on most measures: 0/6 valuation checks.

The issue now is whether X-Energy's current price still leaves enough upside potential relative to its intrinsic value estimate to appeal to new investors.

X-Energy delivered 0.0% returns over the last year. See how this stacks up to the rest of the Electrical industry.

Has X-Energy Run Too Far on Cash Flow?

The Discounted Cash Flow (DCF) model estimates what X-Energy’s future cash flows could be worth in today’s dollars. For X-Energy, the latest twelve month free cash flow is a loss of $243.4 million, and the model assumes that cash flows move from these losses to positive, growing levels over time. On that basis, the DCF points to an estimated intrinsic value of about $12.37 per share.

Compared with the current share price, this indicates that X-Energy trades at roughly a 33% premium to the DCF estimate, so the stock screens as overvalued on this intrinsic value view. The recent announcement that TRISO-X secured an $11 million grant to expand its nuclear fuel campus may help explain some of the optimism already reflected in the price, even though the DCF still points to limited value support at today’s level.

Putting it together, X-Energy currently appears overvalued relative to what its discounted cash flow outlook supports.

Is X-Energy Getting Expensive on Sales?

P/S is often one of the clearer ways to compare early-stage companies like X-Energy that are not yet generating positive earnings.

X-Energy trades on a P/S ratio of about 40.4x, versus an Electrical industry average of 2.8x and a peer group average around 6.5x. That is a very large premium to both the sector and closer peers, which suggests the market is putting a high value on each dollar of revenue at X-Energy relative to other listed companies.

This gap indicates that the multiple is flagging X-Energy as potentially overvalued on a straightforward sales basis, with investors paying many times more for its revenue than for typical Electrical stocks.

On the P/S multiple, X-Energy stock currently appears expensive compared with both its industry and peer benchmarks.

The X-Energy Narrative: What Would Justify Today's Price?

For X-Energy, Simply Wall St Narratives sit between the current valuation puzzle and the future outcomes that might eventually justify, or challenge, today’s share price. They do this by spelling out which growth, margin and earnings paths would need to play out for the stock to be worth materially more or less than it is now on the market. Rather than relying on a single multiple or DCF figure, each Narrative outlines the assumptions behind its fair value so you can judge those against actual results over time. They are available on Simply Wall St's Community page.

If you have a number-driven view on whether X-Energy's role in the new US$200 million nuclear power initiative for AI data centers or TRISO-X's US$11 million Tennessee grant ultimately supports today's valuation, consider sharing a Narrative in the Simply Wall St community. It is a chance to set out your assumptions, track them against future results, and see how your thesis on X-Energy holds up over time.

The Bottom Line

For X-Energy, both the Discounted Cash Flow (DCF) intrinsic value estimate and the P/S multiple currently point to an overvalued stock, and the broader checks do not offset that message. The premium rests heavily on the idea that future projects, including TRISO-X, can convert into sizeable and timely cash flows. From here, the key question for investors is whether X-Energy can deliver revenue growth and project execution that are strong enough to sustain that rich valuation, or whether expectations eventually cool and the multiple resets closer to peers.
