X-Energy Just Went Public in 2026. Here's How It Stacks Up Against Oklo, NuScale, and BWX Technologies.

X-Energy (NASDAQ: XE), a developer of small modular reactors (SMRs), went public at $23 per share on April 24. But today, it trades at just $14. Let's see why X-Energy's stock dropped below its IPO price, and how it compares to three other popular nuclear energy stocks: Oklo (NYSE: OKLO), NuScale (NYSE: SMR), and BWX Technologies (NYSE: BWXT).

What does X-Energy do?

X-Energy's Xe-100 SMRs are much smaller than conventional nuclear reactors. A single Xe-100 generates only 80 MWe, whereas traditional reactors generate over 1,000 MWe. However, the Xe-100 can be deployed in modular "four packs" to expand a plant's capacity.

SMRs can be more easily deployed in remote and off-grid areas. It's already landed major deals with Amazon, Dow, and Energy Northwest (a joint operating agency for public utility districts and municipalities across Washington state).

X-Energy has been scaling up its fuel production capacity to meet that demand, but it doesn't expect to deploy its first commercial reactors until the early 2030s. In 2025, the company still generated $109 million in revenue from its engineering services, government grants, and technical partnerships, while posting a net loss of $390 million. For 2026, analysts expect its revenue to rise another 94% to $212 million as its net loss widens to $430 million.

With a market cap of $4.1 billion, X-Energy trades at 19 times this year's sales. So even though it's dropped nearly 40% below its IPO price, it still can't be considered a bargain.

How does X-Energy compare to Oklo, NuScale, and BWX?

Oklo, NuScale, and BWX are also developing smaller nuclear reactors, but they've all adopted different technologies and strategies. Oklo develops microreactors, which are even smaller and only generate 1.5 MWe. They can also be chained together in their modular plants.

NuScale, which produces a 77 MWe SMR, is more comparable to X-Energy. But NuScale still uses conventional light-water reactor (LWR) technology and standard uranium rods. In contrast, X-Energy's Xe-100 uses high-temperature gas-cooled reactors (HTGRs) that consume TRISO (tri-structural isotropic) particle fuel. That key difference enables the Xe-100 to withstand much higher temperatures than NuScale's water-cooled SMRs.

Even though HTGR microreactors could be much safer than conventional reactors, the U.S. Nuclear Regulatory Commission (NRC) has only approved LWR designs (including NuScale's) so far. NuScale also expects to deploy its first microreactors in the early 2030s.

BWX -- the only large-scale manufacturer of specialized nuclear components, fuel systems, and naval reactor systems in North America -- sells smaller, transportable microreactors that generate 1-5 MWe. But that's only a small part of its massive business, which generates most of its revenue by selling reactors, fuel, and nuclear components to the U.S. Navy.

Is X-Energy's stock worth buying today?

X-Energy has several glaring weaknesses. First, it depends on a specific TRISO pebble fuel that isn't as readily available as uranium. To scale its business, it needs to ramp up the production of that proprietary fuel through its TRISO-X subsidiary.

Second, it trails far behind NuScale and other LWR SMR makers in regulatory clearance. Since TRISO pebble fuel is a newer and untested technology, the NRC will need to view it through a different lens before approving its first reactor designs. Lastly, X-Energy will remain overshadowed by bigger and more profitable nuclear giants -- like BWX -- in this unforgiving market for speculative, unprofitable companies trading at premium valuations.

While X-Energy's stock might take off once it clears its regulatory hurdles, increases its fuel production, and starts deploying its first commercial reactors, it will remain under pressure as long as rising Treasury yields continue to drive investors away from riskier stocks. Therefore, I'd avoid X-Energy and stick with more resilient market leaders like BWX.
