Index additions put X-Energy in front of more institutional investors

X-Energy (XE) has been added to multiple Russell equity and value indices, a shift that could increase the stock’s visibility with index funds and institutional investors that track these benchmarks.

These index inclusions arrive after a challenging month for the stock, with shares down 24.4% while the company continues regulatory work on its Xe-100 small modular reactor and TRISO-X fuel business.

Even with the recent index additions and interest from institutional buyers, X-Energy’s share price performance has been weak this year. The 30 day share price return is down 24.35% and the year to date share price return is down 41.92%, which suggests that recent momentum has faded, despite a 1 day share price return of 2.54% and a last close of US$16.96.

X-Energy now sits at the intersection of fresh index demand and a share price that has pulled back hard in recent months. Is most of the rerating already in the rearview mirror, or is meaningful upside still in front of the stock?

Preferred Price-to-Sales of 41.6x: Is it justified?

X-Energy is currently valued at a P/S ratio of 41.6x, based on a last close of $16.96, which points to a rich valuation relative to revenue.

The P/S ratio compares the company’s market value to its revenue and is often used when a business is unprofitable, as is the case with X-Energy. In this situation, investors are effectively paying a high multiple of current sales for exposure to its Xe-100 reactor and TRISO-X fuel operations while the company continues to report losses.

Compared with the US Electrical industry average P/S of 2.6x and a peer average of 6x, X-Energy trades at a much higher level. This suggests the market is pricing in far stronger prospects than those implied for the wider group. Without a fair ratio to benchmark where this multiple could settle, the current premium appears substantial rather than moderate.

Result: Price-to-Sales of 41.6x (OVERVALUED)

However, X-Energy still faces clear risks, including ongoing losses of $545.783m and the possibility that expectations embedded in its 41.6x P/S ratio may prove too optimistic.

Another view on X-Energy’s valuation

The earlier discussion focused on X-Energy’s 41.6x P/S ratio compared with industry and peer levels. A second lens is our DCF model, which estimates fair value at $12.01 per share, which implies that the current $16.96 price is higher than that estimate of fair value.

That difference leaves you weighing up whether the market is appropriately rewarding X-Energy’s growth story or instead pricing in cash flows that may be ahead of the company’s modeled projections.
