Signal Interpretation
What the spot/term spread is telling you
Term price repricing faster than spot (+27% LT vs. +4% spot in 2025) = structural re-contracting underway. When long-term contract prices rise faster than spot, it means utilities are locking in supply and willing to pay above spot for security of supply. This is exactly what happened in uranium U3O8 in 2023–2024 and preceded the spot price surge. Conversion is now 12–18 months behind the same pattern.
Spot above LT = no incentive to wait. When spot exceeds long-term contract price (as it does now at $69 spot vs. $53.50 LT), utilities buying on spot are paying a premium vs. what they could lock in on term. This is the strongest possible signal to contract now. Every quarter a utility delays locking in conversion, it risks the next spike toward $97+.
The Dec 2024 spike to $97 was not an anomaly — it was a proof of concept. It demonstrated that conversion can price at 10–12x its 2020 lows when supply tightens. Metropolis 2.0 is years away. Orano's expansion targets 13.5M kgU by 2028. Cameco's expansion is incremental. None of this resolves the 2026–2028 gap window.

Western Conversion Capacity
Three facilities supply the entire western world
Russia's TVEL/Rosatom also converts uranium for Russian and some European utilities — sanctioned under PURA for US utilities. Western supply is entirely dependent on these three facilities.

Investor Signals
Five things conversion pricing tells uranium equity investors
1. Cameco (CCJ) conversion margin is an underfollowed earnings lever. Cameco converts at Port Hope and sells conversion services separately from uranium. When conversion prices rise — as they have — Cameco earns more per kgU converted even with flat U3O8 prices. The conversion segment is buried in filings but moving fast. LT conversion price up 27% YoY in 2025.
2. Solstice (SOLS) has conversion exposure — but uranium is a small slice of a large chemicals company. NYSE: SOLS reports UF₆ conversion under its "Alternative Energy Services" sub-line within the Refrigerants & Applied Solutions segment. In 2025, Alternative Energy Services generated $356M of Solstice's $3,886M total revenue — roughly 9%. The dominant business is refrigerants ($1.5B), building solutions ($719M), and electronic/specialty materials ($1.1B). The Metropolis Works backlog ($2B+) and sold-out-through-2028 capacity are real positives, but they are priced into a company where 91% of revenue moves on chemicals cycles, not uranium. Investors seeking conversion exposure via SOLS are buying a diversified specialty chemicals company with a uranium conversion option — not a pure-play. A public pure-play on western UF₆ conversion does not exist.
3. Utilities with un-contracted conversion are the most exposed names. A utility that has U3O8 purchased but no conversion contract is facing spot conversion at $69/kgU — vs. peers who locked in $15–20/kgU in 2020–2021. That cost differential flows directly to fuel cost per MWh. Check utility 10-K fuel supply disclosures for conversion contract coverage alongside uranium contract coverage.
4. The Dec 2024 spike to $97 created a false sense of resolution. The pullback to $69 felt like "the problem is over." It wasn't. Conversion capacity is still sold out. Metropolis 2.0 isn't built. Orano's expansion is incremental. The next demand surge — when PURA waivers fully expire and utilities scramble for western-only supply chains — could retest $97 or exceed it. The pullback is a re-entry window, not a resolved constraint.
5. Conversion is the pre-enrichment chokepoint — it amplifies SWU tightness. You cannot enrich uranium that hasn't been converted to UF₆. When the SWU gap (2026–2028 western enrichment deficit) drives enrichment buying, it simultaneously pulls on conversion. Conversion tightness and enrichment tightness are correlated shocks, not independent ones. See the Western SWU Gap report for the enrichment half of this picture.
