Daily Nuclear & Uranium Market Recap
Tuesday, February 17, 2026
Market Overview
The nuclear and uranium complex traded with a pronounced split today: nuclear power generators and advanced reactor names rallied while upstream uranium miners and physical-linked plays sold off. Uranium spot last confirmed at $89.75/lb (Friday close), with the weekly range of $85.70 to $89.75 highlighting continued sensitivity to marginal buying in a thin physical market. The session’s dominant catalyst was a Reuters headline that the U.S. will restart domestic uranium enrichment, partly in partnership with France, a major policy escalation that lit up the downstream/fuel-cycle complex while failing to lift miners.
Key Equity Movers, Winners
Kronos Bio (KBL) closed at $3.34, +13.61%, the day’s top gainer across the nuclear-adjacent universe. Thinly traded name with minimal volume, likely a speculative squeeze.
Constellation Energy (CEG) closed at $303.99, +5.39% on 5.3M shares, breaking above $300 for the first time in recent sessions. Range: $303.00 to $304.00. CEG continues to trade as the premier large-cap nuclear power proxy, benefiting directly from the U.S. enrichment restart headline and AI/data center power demand narrative.
ASP Isotopes (ASPI) closed at $5.40, +3.45% on 3.2M shares, rallying on enrichment tailwinds. ASPI’s laser-based isotope enrichment technology is directly relevant to the U.S. push for domestic enrichment alternatives, and the General Matter $900M fundraise for enrichment disruption validates the TAM.
Bloom Energy (BE) closed at $144.02, +3.06% on 7.8M shares, lifting alongside CEG and VST in the nuclear-adjacent power solutions complex.
Nano Nuclear Energy (NNE) closed at $25.51, +2.90% on 1.4M shares. Range: $25.02 to $25.55. Micro-reactor names benefiting from the broader nuclear policy momentum.
Oklo (OKLO) closed at $67.43, +2.65% on 6.1M shares, reclaiming the $67 level after last week’s brutal selloff to $63. Range: $67.38 to $67.50, a tight close near the highs suggesting buyers have stabilized the name above $65 support.
Key Equity Movers, Laggards
NuScale AI (NUAI) closed at $4.34, down 11.79% on 3.0M shares, the day’s worst performer. A full reversal of Friday’s +6.96% pop, classic small-cap whipsaw.
enCore Energy (EU) closed at $2.50, down 5.30% on 2.7M shares, extending the upstream miner weakness. EU is now down meaningfully from early-February highs.
Mirion Technologies (MIR) closed at $21.56, down 4.22% on 3.2M shares, giving back nearly all of Friday’s +4.80% gain. Intraday range of $21.28 to $25.22 suggests a volatile open that faded hard.
Uranium Energy Corp (UEC) closed at $15.04, down 3.09% on 8.6M shares, continuing its slide from the Feb. 9 high of $17.30. UEC has now lost 13% in six sessions and is trading below Goldman’s $18 price target by 16%. March 11 earnings loom as the next catalyst.
Ur-Energy (URG) closed at $1.55, down 1.91% on 5.3M shares. Upstream miners broadly under pressure as the market rotates downstream.
Cameco (CCJ) closed at $112.99, +0.08% on 3.7M shares, essentially flat after last Friday’s post-earnings selloff of 2.58%. Range: $111.74 to $114.35. The $112 level is being tested as support; a break below opens the path to $104.87 (50-DMA).
Catalysts & Headlines
U.S. to Restart Uranium Enrichment with French Partners (Reuters) The headline of the day. U.S. Energy Secretary announced plans to restart domestic enrichment capacity in partnership with French entities, almost certainly involving Orano or EDF subsidiary Framatome. This is the most significant nuclear fuel policy headline since the DOE’s $2.7B enrichment contract awards in January. It directly benefits LEU (sole U.S. enricher, +0.07% flat today as the market digests), LTBR (Lightbridge fuel technology, down 0.69%), and validates ASPI’s (+3.45%) enrichment disruption thesis.
General Matter, $900M Enrichment Disruptor Energy Intelligence profiled General Matter’s ambition to single-handedly supply all U.S. enrichment demand using next-gen centrifuge technology. This is a long-term competitive overhang for LEU and Urenco, though execution risk is extreme and commercial-scale production is years away.
Uranium Spot: “Highly Sensitive to Marginal Buying” The Uranium Spotlight weekly highlighted that spot opened last week at $85.70 and closed at $89.75, a +$4.05 weekly move driven by a handful of buyers. Additional macro context: China consolidating Namibian supply via Bannerman, Niger seizing Orano assets, India’s Adani entering nuclear, and Japan completing its first physical uranium shipment in roughly 11 years.
LEU Flat at $199.33 Despite Enrichment Headlines Centrus traded a muted $197.50 to $200.00 range on just 1.1M shares. The stock is essentially pinned at $199 following last week’s earnings-driven collapse from $270. The Fluor EPC partnership and today’s U.S. enrichment restart headline have arrested the decline but not yet sparked a recovery.
SEQH Desk View
Today’s session crystallized the rotation thesis we flagged last Friday: capital is flowing out of upstream miners (UEC down 3.09%, EU down 5.30%, URG down 1.91%) and into power generators (CEG +5.39%, VST +1.23%) and enrichment/fuel-cycle plays (ASPI +3.45%, OKLO +2.65%). The Reuters enrichment restart headline is a genuine policy catalyst, but the muted LEU reaction (+0.07%) tells you the stock is still in post-earnings damage control mode. $199 is a floor, not a launch pad, until the Street rebuilds confidence in quarterly execution.
The most important signal today is CCJ’s flatline at $112.99. The bellwether posted a strong Q4 (adj. EPS +115% YoY) but has now traded sideways-to-down for four sessions, suggesting the miner complex is fully valued at current spot levels. If CCJ breaks below $111.74 (today’s intraday low), the next support is the 50-DMA near $105, and that would likely drag UEC, DNN, and the rest of the upstream cohort with it.
DNN at $3.80 on 42.1M shares is again the volume standout, massive turnover on a 0.53% move signals continued institutional block activity ahead of the Phoenix ISR FID. UEC at $15.04 is now down 13% off the Feb. 9 high and approaching a critical level. If $15 breaks, the December gap-fill zone near $13.50 becomes the target. March 11 earnings need to deliver.
Spot uranium at $89.75 remains the anchor bull case. Until the physical market rolls over, every equity pullback is a potential re-entry. The question is timing, and today’s data says the market wants fuel-cycle and power-gen exposure, not miners.
