The uranium thesis has been a mining story since 2021 — supply discipline at Kazatomprom, Cameco's restart pace, the exit of Russian-origin material from Western buyers. By 2026 the spot uranium price has consolidated at a level that allows for production restart economics, and the mining layer is now well-priced. The interesting tightness has moved downstream. Conversion services — the UF6 step — and enrichment SWU pricing are at multi-decade highs, and the constraint is structural rather than cyclical.
Key takeaways
- UF6 conversion pricing is at multi-decade highs.
- Enrichment SWU pricing has more than tripled since 2022.
- Western conversion and enrichment capacity remains structurally tight.
- New capacity additions are multi-year projects.
Why the bottleneck shifted
The Russian fuel-cycle exit created structural shortages at every step downstream of mining. Conversion capacity in the West is concentrated in a handful of facilities, all running at or near nameplate. Enrichment expansions are multi-year. Replacing Russian-origin SWU at Western utilities has been the single largest demand event the cycle has had.
- UF6 conversion: capacity-constrained in the West
- SWU: multi-year tightness
- Russian replacement demand: structural
- New capacity: 2027–2030 timeline
How to play it
The pure-play mining names have rerated. The conversion and enrichment names are still rerating. The fuel-cycle integrated utilities have a real margin opportunity.
What could disrupt it
A Russian re-engagement of Western fuel-cycle markets. Politically unlikely.
Where capacity is being added
Centrus, Orano expansions, Cameco conversion. Multi-year.
Fuel cycle pricing
| Component | 2022 price | 2026 price |
|---|---|---|
| U3O8 (spot) | $50 | $95 |
| UF6 conversion ($/kgU) | $30 | $80 |
| SWU ($/SWU) | $55 | $180 |
The uranium bull is now a conversion and enrichment story.
Frequently asked questions
Is the mining trade over?
Mostly priced, not over.
How long does conversion tightness last?
Multi-year.
Who benefits most?
Western conversion and enrichment.
The bottom line
The uranium thesis has moved downstream. Conversion and enrichment are the right expressions now.
