X-Energy (XE) shares are back in focus after the company was named a Tier 1 partner and founding member of the Prometheus project, a $60 million AI driven nuclear research initiative backed by major industry players.

The recent Prometheus announcement comes after a tough stretch for X-Energy, with the share price at $15.92 and the year-to-date share price return down 45.48%. However, a 15.11% 7-day share price return suggests short-term momentum has picked up despite a 24.51% 30-day and 45.48% 90-day share price decline.

The sharp rebound in X-Energy after heavy year to date declines leaves a simple tension: is the market suddenly reassessing the business after the Prometheus news, or is this just sentiment snapping back ahead of stretched valuation checks to come?

Preferred Price-to-Sales Multiple of 39.1x: Is It Justified?

With X-Energy at $15.92, the stock is being valued on a very rich price-to-sales basis compared both to its own electrical equipment peers and the wider US Electrical industry.

The preferred metric here is the P/S ratio, which compares the total market value of the company to its revenue. For a business like X-Energy that is currently loss making, investors often fall back on P/S because there are no earnings to use in a P/E ratio. The multiple effectively reflects what the market is willing to pay today for each dollar of current sales.

According to Simply Wall St data, X-Energy trades on a P/S of 39.1x, while the peer average sits at 6.6x and the US Electrical industry average is 2.7x. That is a steep premium. It suggests the market is already baking in very strong expectations, even though the company reports a loss of $545.8 million and is forecast to remain unprofitable over the next 3 years.

There is also insufficient data to estimate a P/S fair ratio that the market could move toward over time. Investors looking at X-Energy are therefore working without that extra reference point when judging how stretched this 39.1x headline multiple might be.

Result: Price-to-sales of 39.1x (OVERVALUED)

However, X-Energy still carries clear risks, including its $545.8 million loss and the possibility that forecasts for ongoing unprofitability may limit investor appetite for that rich P/S multiple.

Another View: SWS DCF Model Points to a Different Story

The rich 39.1x P/S ratio presents X-Energy as expensive, but the SWS DCF model offers a different angle. In this view, the stock at $15.92 is trading above an estimated future cash flow value of $12.31, suggesting it may also be overvalued on cash flow terms.

For readers who want to see how the cash flow assumptions compare in detail, it is worth reviewing how the model is built and stress testing the inputs that matter most, such as revenue growth and timing of potential profitability, via the Look into how the SWS DCF model arrives at its fair value.
