HALEU wins, Russian supply still bites
- The core business still sells LEU, the fuel used by today’s nuclear power plants.
- The growth story is HALEU, a higher-enriched fuel many advanced reactors need.
- Centrus secured a $900 million DOE HALEU task order, shifting the story from award risk to build-out risk.
- Russian supply is still the bridge, but Russian export licenses now add timing risk to deliveries.
- Backlog was $3.9 billion at March 31, 2026, but a large part depends on future capacity and funding.
A funded shot at U.S. enrichment
Centrus is one of the clearest public bets on the United States rebuilding its own uranium enrichment supply chain. The big change is that the company secured a $900 million Department of Energy task order for commercial-scale HALEU production. HALEU is a richer nuclear fuel that many advanced reactors need.
That moves the bull case into a new phase. The question is no longer only whether the DOE sees Centrus as important. It does. The question is whether Centrus can build the plant, make enough centrifuges, control costs, and bring new capacity online on time.
The old LEU business gives Centrus a cash flow bridge. It sells enrichment services and uranium products to utilities under medium- and long-term contracts. DOE waivers allow imports of Russian LEU for committed deliveries through 2027, which helps keep that bridge standing.
The bear case is that the bridge is narrow. Russia now requires TENEX to get export licenses for each shipment to Centrus through 2027. After that, U.S. Russian import limits become much more important. Centrus needs domestic LEU capacity too, and that path is not as funded as the HALEU task order.
Fuel sales today, build-out tomorrow
Centrus has two businesses. The LEU segment sells the enrichment part of nuclear fuel, called SWU, plus uranium products such as natural uranium hexafluoride and enriched uranium product. Its customers are mostly electric utilities that run nuclear plants.
This segment can be profitable, but the timing is lumpy. A few large utility orders can move a quarter. In Q1 2026, individual SWU customer orders averaged about $13.7 million, so a delivery shift can change reported revenue a lot.
Technical Solutions is the growth arm. It does engineering, manufacturing, and enrichment work for the U.S. government and private customers. Its main project is HALEU production for the DOE at Piketon, Ohio.
The model breaks if supply does. Centrus still relies heavily on Russian LEU from TENEX through 2027. It also needs DOE funding, private capital, or customer offtake deals to turn its Ohio and Tennessee expansion plans into real production.
What Centrus sells
Separative Work Units
SWU is the enrichment work inside LEU. This is the main product sold to nuclear utilities in the legacy LEU segment.
Natural uranium hexafluoride
This is uranium feed material used in the enrichment process. Centrus sells it directly or as part of a larger fuel package.
Enriched uranium product
EUP bundles uranium feed and enrichment into one sale. It helps customers buy a more complete fuel component.
HALEU
HALEU is high-assay, low-enriched uranium. It is critical for many advanced reactor designs and is the center of the DOE-backed growth plan.
Engineering and manufacturing services
Centrus uses its centrifuge and nuclear fuel know-how for government and private projects. This work supports the larger goal of rebuilding domestic enrichment.
HALEU deconversion services
Centrus is exploring deconversion with Oklo at Piketon. This would help turn enriched material into forms that fuel makers can use.
Two segments, different jobs
Mix is based on Q1 2026 revenue: LEU was $44.6 million and Technical Solutions was $32.1 million, out of $76.7 million total. LEU is still larger, but Technical Solutions grew 47% year over year while LEU fell 13%.
What could break the thesis
Russian export licenses slow or stop
High impact · Medium oddsU.S. waivers allow certain Russian LEU imports, but Russia now requires TENEX to get a license for each export shipment to Centrus. Management says TENEX has mostly received licenses in the regular course, except for isolated delays. There is still no certainty that future licenses will arrive on time.
Post-2027 LEU supply cliff
High impact · Medium oddsThe U.S. ban on Russian LEU imports becomes a much bigger issue after 2027. Centrus has other sources, but the filing says they are not enough to replace TENEX supply. The company needs new domestic LEU capacity, more waivers, or other supply deals to protect its long-term order book.
HALEU build-out slips
High impact · Medium oddsThe $900 million HALEU task order is the main upside path. It also brings construction, supply chain, hiring, regulatory, and operating risk. Centrus has signed engineering and construction partners, but the first new centrifuges are not expected to come online in Ohio until 2029.
Government funding changes
Medium impact · Medium oddsTechnical Solutions depends on DOE contracts and appropriations. Centrus also disclosed uncertainty tied to federal funding reviews and the timing of future government support. Even awarded contracts can depend on task orders, options, and funded scope.
Customer and quarter lumpiness
Medium impact · High oddsThe LEU business can swing by quarter because customer deliveries are large and uneven. In Q1 2026, average SWU customer orders were about $13.7 million. A small timing change can make revenue or profit look better or worse than the real long-term trend.
Trade rules and tariffs raise costs
Medium impact · Medium oddsUranium and enrichment are now tied to national security policy. Section 232 talks and other trade actions could still lead to tariffs or restrictions. New costs on uranium, SWU, shipping, or payments could hurt margins and supply reliability.
In one breath
What does Centrus Energy do?
Centrus supplies nuclear fuel components to utilities and does technical work for the U.S. government. Its main products are LEU for current reactors and HALEU for many advanced reactor designs.
Why is the DOE contract important for LEU stock?
The $900 million DOE HALEU task order gives Centrus a funded path toward commercial-scale HALEU production. It confirms the company’s strategic role, but it also starts the hard part: building and operating the capacity.
Why does Russian supply matter so much?
Centrus has relied on TENEX for a large part of its LEU supply. U.S. waivers help through 2027 for committed deliveries, but Russia must approve exports shipment by shipment, which can delay or disrupt the business.
Is Centrus already producing HALEU?
Yes. Centrus completed its Phase 2 target by delivering 900 kilograms of HALEU to the DOE in June 2025. The next challenge is moving from a demonstration cascade to commercial-scale production.
