This node covers uranium concentrate, usually reported as U3O8, before it enters conversion, enrichment, and fuel fabrication. Miners extract ore or recover uranium-bearing solution, processing plants concentrate it into saleable feedstock, and utilities buy contracted pounds for reactor fuel inventories. The current basket ranks companies by source-backed pounds, realized price, unit cost, inventory, restart cadence, permits, financing, and construction proof because those are the mechanisms that turn fuel-security demand into company cash flow.
What the stack is: the front end of the nuclear fuel chain. It includes mined uranium ore, in-situ recovery resin, conventional mill feed, yellowcake/U3O8 concentrate, producer inventory, and term-contract delivery obligations.
What it does: it supplies the raw uranium input that later conversion plants turn into UF6, enrichment plants raise to required U-235 assays, and fuel fabricators assemble into reactor fuel. Without contracted feedstock, downstream fuel-cycle capacity cannot load reactors.
Main pieces: ISR wellfields and header houses, conventional mines, ore stockpiles, resin transport, mills such as White Mesa, drying and packaging, conversion-facility inventory, utility term contracts, physical uranium holdings, and project-financing packages for future mines.
Where it sits: physically at mines, ISR fields, mills, warehouses, and conversion-facility inventory accounts; operationally it sits before conversion/enrichment and before utility fuel assemblies enter reactor reload schedules.
How the theme uses it: nuclear-power demand needs reliable fuel reloads. The theme reaches producers when utilities contract pounds, accept deliveries, pay realized uranium prices, and producers deliver at costs that leave margin after mine, mill, transport, financing, and development spending.
Terms used later: U3O8 is uranium concentrate; ISR means in-situ recovery through wellfields rather than open-pit or underground mining; realized price is the actual contract or spot price received; cash cost per pound excludes some non-cash items; offtake is a customer purchase contract; FID is a final investment decision to build a project.
Report boundary: this node is a tactical report layer. It ranks the current uranium-feedstock basket, relative value drivers, setup labels, confirmation triggers, invalidation levels, and chart provenance. Durable company research, raw source registries, and sector thesis maintenance stay in the linked knowledge pages. Price and volume context comes from read-only discovery daily_ohlc through 2026-06-12.
Current Setup
Fuel-feedstock gatePolicy support matters only when contracted pounds become delivered pounds and margin.
Utilities need uranium concentrate before any conversion or enrichment step can run. The strongest evidence is realized price, delivery volume, cost per pound, and funding that protects per-share economics.
Positive proofCCJ anchors current cash conversion.
URG and UUUU add U.S. operating proof; UEC, DNN, NXE, and EU need cleaner cost, funding, or construction evidence.
Conversion gateContracts and costs decide the equity read.
Watch utility deliveries, realized price, cash cost per pound, construction spend, and share-count discipline.
Primary constraintSpot uranium can move before company cash flow.
Developers still need permits, offtake, capex control, financing, and mine ramp evidence.

Proof pointMargin, cash flow, funding
Uranium feedstock matters because the reactor fleet cannot run on policy language or power-demand forecasts; it needs contracted pounds. EIA's 2024 uranium marketing data show U.S. reactor owners bought 55.9 million lb U3O8e, 91% of deliveries came through long-term contracts, and utilities still had 184 million lb of unfilled 2025-2034 requirements. EIA domestic production was only 677,000 lb in 2024, so allied mine output, inventories, restarts, and future projects remain important inputs for fuel security.
The strongest support is visible contracting and operating evidence. CCJ has the cleanest current conversion through Q1 2026 delivered pounds, realized uranium price, uranium adjusted EBITDA, 2026 production guidance, and utility delivery commitments. URG and UUUU add current U.S. operating proof with disclosed sold pounds and cost data. UEC, DNN, and NXE add future U.S. and Canadian supply if ISR recovery rates, construction schedules, financing, offtake terms, and capital budgets stay inside disclosed plans.
The main headwind is that spot uranium can lift sentiment before company cash flow arrives. Developers still face permits, capex, debt or equity funding, offtake terms, and construction risk. UEC needs more mined-cost and recovery-rate proof, UUUU has non-uranium capital calls, EU needs margin improvement after Q1 delivered cost roughly matched realized price, and URG needs a durable local knowledge lane. LEU, HALEU, conversion, enrichment, and fuel fabrication are routed to the sibling fuel-cycle node because they bottleneck later fuel steps rather than U3O8 feedstock.
Right-rail setup labels and charts use weekly bars aggregated from discovery daily_ohlc through the completed week ended 2026-06-12. Fundamental claims route to the Energy sector lane, the power-scarcity theme, linked security lanes, and official company or government sources where local lanes are missing.
Basket
This basket is hand-curated from the parent theme, a 13-primary-agent research tournament, one merge/select pass, linked knowledge coverage, bounded official-source checks, and read-only discovery setup work. Ranking uses source-backed feedstock economics and relative value first, balance sheet and execution risk second, and technical timing third. URG and EU stay in the basket because their official operating evidence is relevant; both are flagged as source-gap names until local security lanes exist. LEU, physical uranium trusts, royalty vehicles, ETFs, and uncovered foreign producers remain sidecar references or sibling-node routes.
Allied uranium and fuel-services platform with the clearest delivered-pound, realized-price, and EBITDA evidence.
Market cap$50.8B
Next earningsNot confirmed
Latest qtr revenueC$845M
Role in stack
Cameco sells contracted uranium pounds to utilities and also owns fuel-services and Westinghouse exposure. This node ranks it for the feedstock route: deliveries, realized uranium price, inventory sourcing, mine reliability, and production guidance.
Revenue mix
Uranium is the current anchor; fuel services and Westinghouse add related nuclear exposure but are not the main U3O8 feedstock mechanism. Q1 2026 uranium adjusted EBITDA was C$423M on 7.8M lb sold at US$66.21/lb.
Latest qtr revenue
Q1 2026 consolidated revenue was C$845M, from Cameco's May 5, 2026 Q1 release. The same release kept 2026 production guidance at 19.5M-21.5M lb Cameco share and delivery guidance at 29M-32M lb.
URGUr-Energy
Small-cap U.S. ISR producer with direct Q1 sold-pound, cost-per-pound, and cash evidence.
Market cap$691M
Next earningsNot confirmed
Latest qtr revenue$3.9M
Role in stack
Ur-Energy runs ISR uranium at Lost Creek and is starting Shirley Basin. Utility contracts turn captured, dried, packaged, and shipped U3O8 into revenue when sold pounds clear at prices above cash cost.
Revenue mix
Pure uranium ISR exposure from Lost Creek and Shirley Basin. The source gap is important: no local security lane exists, so current company evidence relies on official releases and discovery chart coverage.
Latest qtr revenue
Q1 2026 revenue was $3.9M from 55,000 produced lb sold at $70.98/lb, with $37.51/lb cash cost per pound sold, from Ur-Energy's May 8, 2026 Q1 release.
U.S. uranium producer and White Mesa processor with strong Q1 uranium sales but broader critical-minerals capital calls.
Market cap$5.34B
Next earningsNot confirmed
Latest qtr revenue$35.8M
Role in stack
Energy Fuels mines uranium, processes ore at White Mesa, sells into utility contracts or spot opportunities, and uses inventory conversion to create cash. The gate is whether cost applicable to uranium revenue falls as Pinyon Plain and mill throughput improve.
Revenue mix
Q1 2026 revenue was almost entirely uranium; REE and heavy-mineral-sands projects add strategic optionality but also capex, financing, and reporting complexity outside this feedstock node.
Latest qtr revenue
Q1 2026 total revenue was $35.838M in the local UUUU security lane, tied to 510,000 U3O8 lb sold at $70.04/lb and $42.11/lb cost applicable to uranium revenue.
U.S. ISR platform with liquidity and inventory, but mined-pound and mine-cost proof still lag valuation.
Market cap$7.43B
Next earningsNot confirmed
Latest qtr revenue$20.2M
Role in stack
UEC owns U.S. ISR platforms, uranium inventory, and development assets. The feedstock route improves when Christensen Ranch and Burke Hollow produce more pounds with disclosed recovery rates, costs, cash burn, and share-count discipline.
Revenue mix
Transition-stage uranium platform. Latest local evidence shows revenue from purchased uranium inventory sales rather than mature mined-production sales, so operating proof needs produced pounds and cost disclosure.
Latest qtr revenue
Latest local lane evidence is FY2026 Q2, period ended January 31, 2026, with a $20.2M purchased uranium inventory sale and $10.0M gross profit. Q3 FY2026 results were a known next evidence item, not in the inspected local lane.
Post-FID Phoenix developer with a defined construction path and limited current revenue.
Market cap$3.38B
Next earningsNot confirmed
Latest qtr revenueNot disclosed
Role in stack
Denison is ranked for future feedstock from Phoenix/Wheeler River, plus physical uranium inventory. The cash route depends on construction execution, cost-to-complete, contract terms, mid-2028 first-production timing, and future ISR recovery.
Revenue mix
Current revenue is small toll-milling and services exposure; the investment case is Phoenix construction and future uranium output. Physical uranium inventory adds commodity exposure but does not replace construction proof.
Latest qtr revenue
Q1 2026 quarterly revenue was not available in the inspected local lane or clipped Q1 release summary. Denison's 2025 annual report recorded C$4.918M of 2025 toll-milling revenue, and the source trail records this as a revenue-source limitation.
Licensed Rook I/Arrow developer with large future supply potential and no product revenue yet.
Market cap$8.04B
Next earningsNot confirmed
Latest qtr revenueC$0 product
Role in stack
NexGen would add large Canadian feedstock if Rook I/Arrow construction, financing, offtake, and commissioning stay on track. Its current role is future supply option, not current utility delivery.
Revenue mix
Pre-revenue project developer. Value is concentrated in Rook I/Arrow, with Patterson Corridor East as exploration optionality. Liquidity helps near-term work, but final construction financing and cost discipline remain gating items.
Latest qtr revenue
Q1 2026 product revenue was C$0 in the local NXE lane, sourced to the Q1 2026 MD&A/financial statements. The key metrics are cash, short-term investments, construction spend, offtake, and financing terms.
EUenCore Energy
Direct U.S. ISR exposure kept in the basket, but Q1 margin evidence and local source coverage are weaker.
Market cap$321M
Next earningsNot confirmed
Latest qtr revenueNot disclosed
Role in stack
enCore is a South Texas ISR producer. Rosita, Alta Mesa, Upper Spring Creek, extraction rate, delivered pounds, realized price, delivered cost, and liquidity decide whether U.S. feedstock exposure creates margin.
Revenue mix
Direct uranium ISR exposure. No local security lane exists, so this row uses official Q1 release evidence and local OHLC coverage rather than a maintained company lane.
Latest qtr revenue
The fetched Q1 2026 release disclosed 270,000 lb delivered into contracts at $67.78/lb and weighted average delivered cost of $68.02/lb, but it did not expose a total revenue line in the inspected text.
Market caps use read-only discovery instruments.market_cap values queried on 2026-06-13. Nasdaq earnings pages checked on 2026-06-13 showed no current earnings-date data for the seven tickers, so every card uses Not confirmed. Latest-quarter revenue fields use official Q1 releases or local security lanes; DNN and EU are marked where a quarterly total revenue line was not available in inspected sources.

Next-earnings checks used Nasdaq earnings pages for CCJ, URG, UUUU, UEC, DNN, NXE, and EU, accessed 2026-06-13. Those pages showed no current earnings-date data in the fetched text, so the Basket cards use Not confirmed.
Latest-quarter revenue sources: CCJ Q1 2026 C$845M from Cameco's May 5, 2026 release; URG Q1 2026 $3.9M from Ur-Energy's May 8, 2026 release; UUUU Q1 2026 $35.838M from the local UUUU lane's Q1 2026 10-Q/results source; UEC FY2026 Q2 $20.2M purchased-inventory sale from the local UEC lane; NXE Q1 2026 C$0 product revenue from the local NXE lane's Q1 MD&A/financial statements.
DNN and EU have revenue limitations in this pass. DNN's Q1 2026 quarterly revenue line was not available in the inspected lane or clipped Q1 release summary; the 2025 annual report recorded C$4.918M of 2025 toll-milling revenue. The fetched EU Q1 2026 release disclosed 270,000 lb delivered at $67.78/lb and $68.02/lb weighted average delivered cost, but the fetched text did not expose a total company revenue line.
Discovery And Chart Provenance
Read-only discovery coverage checks used daily_ohlc rows from ../discovery/data/discovery.duckdb. CCJ, URG, UUUU, UEC, DNN, NXE, and EU had local rows through 2026-06-12; EU coverage begins 2023-01-23 and the other six names begin 2021-05-12.
Weekly bars group daily rows by calendar week: first open, maximum high, minimum low, final close, and summed volume.
Setup rows use 20-week and 100-week EMAs computed from weekly closes before clipping the visible chart window. The 2026-06-12 row is a completed Friday weekly close.
The right-rail chart contract is /api/securities/{ticker}/chart?frequency=weekly&window=3y&as_of=latest. Node HTML does not embed OHLC arrays.
Representative API check for CCJ on 2026-06-13 returned 157 weekly rows, resolved as of 2026-06-12, from reports.weekly_ohlc+discovery.daily_ohlc. The API row format exposed sma20 and ema100; treat any strict 20-week EMA display as a chart-service refresh item unless the API adds an explicit ema20 field.
Lineage checks for selected names showed May 2026 backfill records even though the daily table contains rows through 2026-06-12, so chart freshness is anchored to table coverage rather than lineage labels alone.
Known Gaps
URG is ranked second on official operating evidence and chart posture, but no local security lane exists at publication time.
EU is kept for direct U.S. ISR exposure, but no local security lane exists and the latest margin evidence is weak.
UEC production figures should be reconciled against the next local security-lane refresh before increasing rank on operating proof alone.
LEU, HALEU, conversion, enrichment, and fuel fabrication belong in the sibling fuel-cycle node; Russian LEU policy is context rather than direct U3O8 miner revenue proof.
Physical trusts, royalty vehicles, ETFs, KAP, PDN, BMN, DYL, GLO, LOT, and other uncovered lines were reviewed as sidecar references but kept outside this first ranked basket.
