Centrus Energy (LEU): what it does, how it makes money, and why SMRs need its fuel

The standard $LEU story lumps Centrus in with the uranium miners: a nuclear name that goes up when uranium does. That misses what makes it unusual. Centrus does not dig uranium. It enriches it, and it runs the only US-licensed facility currently producing the specific enriched fuel that most next-generation reactors are designed to use.

The more accurate frame: if small modular reactors and advanced reactors get built at scale, they need a fuel called HALEU, and today Centrus is the only US producer. That is a genuine chokepoint. It is also an early one: production is still at first-of-kind scale. This piece walks through what Centrus does, how it makes money, where it sits in the nuclear stack, and the scale-up risk underneath. Figures are as of 2026-09-17 unless noted.

Why it matters now

The stock is down about 35% over the year to 2026-09-17, and about 22% over three months, even as the AI-power story keeps pulling attention toward nuclear. A chokepoint story and a falling price can coexist when the market is pricing timing: the chokepoint only pays at scale if the reactors that need the fuel actually get built on schedule. That is the question worth answering carefully.

What does Centrus do?

Centrus is a nuclear fuel company. Its core activity is enrichment: raising the share of the fissile isotope U-235 in uranium so it can be used as reactor fuel.

Today's large reactors burn low-enriched uranium, at up to 5% U-235. Most advanced reactor and small modular reactor designs, including those from Oklo, NuScale, X-energy and TerraPower, are built around HALEU, enriched to between 5% and 20%. HALEU lets those reactors run smaller, longer and more efficiently. The desk's framing is blunt: no HALEU, no SMRs at commercial scale.

Per QA's desk thesis, the structure is what makes Centrus matter:

• The 2024 US ban on Russian uranium imports removed what had been the dominant source of HALEU.
• Centrus's Piketon, Ohio facility is the only US-licensed alternative currently producing.
• The Department of Energy has awarded multi-year contracts to scale up production: the first cascade of centrifuges is producing, and a second is in expansion.

How Centrus makes money

Centrus earns revenue from supplying enrichment, today largely for the existing reactor fleet, plus government contracts for HALEU production. The HALEU business is the growth story, but it is early: current HALEU shipments are first-of-kind quantities for a Department of Energy customer, not commercial-scale sales.

The headline risk sits right there: scale. Centrus is effectively pre-revenue at material HALEU scale, and every step up requires new centrifuge cascades, which are capital-intensive and depend on continued commitments from the DOE and from reactor customers. That is the number to hold onto through the rest of this piece.

Where it sits in the nuclear bubble

Centrus sits in QA's Nuclear / SMR bubble and maps onto the Nuclear theme.

The useful way to place Centrus is by position in the fuel chain. Miners dig uranium. Enrichers like Centrus turn it into reactor fuel. Reactor developers like Oklo ($OKLO) and NuScale ($SMR) build the machines that burn it, and operators of today's fleet, like Vistra with its existing nuclear plants, sell the power. Centrus's value rises and falls with the reactor developers downstream, because they are the future buyers of HALEU.

Its peers show exactly that. LEU's tightest correlations in the QA universe (252 trading days, market beta stripped out) run to Oklo (0.75), NuScale (0.73) and Nano Nuclear Energy ($NNE, 0.69), all reactor-developer names, ahead of uranium producers like Uranium Energy ($UEC, 0.64). LEU trades with the SMR story, not with the uranium price. The full peer table is on /stocks/leu.

The numbers

The Street mean target is an estimate, an average of analyst opinions, not a promise or a QA view. On a name whose payoff depends on reactors that are not built yet, it mostly measures how much of that future the consensus is willing to count.

The bull case

• A real chokepoint: the only US-licensed facility currently producing HALEU, the fuel most advanced reactors and SMRs are designed for.
• The Russian import ban removed the previous dominant supplier.
• DOE contracts support the scale-up, with a first cascade producing and a second in expansion.
• The AI-power story pulls SMR demand forward, and HALEU demand follows.

The bear case

• Early scale. Current HALEU shipments are first-of-kind quantities; Centrus is effectively pre-revenue at material HALEU scale.
• Capital intensity. Each new cascade needs capital and continued DOE and customer commitments.
• Single-facility risk. Piketon is the only producing US HALEU plant, so any disruption there hits the whole story.
• The multiple re-rated on the SMR thesis, with reversion risk if commercial SMR deployment slips.

How to access

Centrus Energy trades on NYSE American as LEU. To trade it from a US-retail account alongside the rest of the nuclear names, see /stack/ibkr. The live ETF holdings breakdown is on /stocks/leu.

Bubble-correlation shifts and rule-based alerts on $LEU are part of /pro.

What to watch

• Progress of the second cascade and any further DOE awards.
• The first commercial HALEU contracts with reactor developers, the step from government pilot to commercial business.
• SMR deployment timelines at Oklo, NuScale and the others, since they set when HALEU demand arrives.
• The curated $183 level (marked 2026-04-25) sits about 22% above the 2026-09-17 close, so it is an overhead reference, not support. It is an observable level, not a trade level or a target.
