NEW YORK, January 1, 2026, 21:05 ET — Market closed
- Denison Mines’ U.S.-listed shares last ended the year higher as U.S. markets shut for New Year’s Day.
- Uranium prices and nuclear fuel-cycle headlines remain the key swing factors for the group.
- Traders are watching Friday’s reopen and near-term price levels after a choppy final session.
Denison Mines Corp’s U.S.-listed shares last ended up about 1% at $2.66 on Wednesday, the final U.S. trading session of 2025. The NYSE American-listed stock traded between $2.61 and $2.68, with about 22 million shares changing hands, LSEG data showed.
U.S. stock and bond markets were closed on Thursday for New Year’s Day, leaving uranium-linked names without fresh price discovery until Friday’s open.
That pause matters because uranium developers and explorers can swing on small shifts in the commodity and broader risk appetite, even when there is little company-specific news.
Spot uranium — the cash price for near-term delivery — ended Dec. 31 at $81.65 a pound, down 0.24% on the day but up about 6.9% over the past month, TradingEconomics data showed. 1
Peers were mixed into the holiday break: Cameco ended Wednesday up 0.1%, Energy Fuels rose 1.9% and Uranium Energy fell 0.6%, while the Global X Uranium ETF eased 0.2%, LSEG data showed.
The nuclear-fuel supply chain also stayed in focus after Urenco USA said it completed its inaugural production run of uranium enriched to 8.5% U-235 at its New Mexico facility. U-235 is the isotope used in most reactor fuel, and Urenco said the run supports so-called LEU+ — uranium enriched between 5% and 10% — used for some advanced reactor designs. “We are the only domestic supplier of enriched uranium,” Urenco spokesman Jeremy Derryberry said. 2
While enrichment is a different link in the chain than mining, the update underscored a broader push to secure nuclear fuel supply — a theme that has kept uranium equities in focus.
Denison, based in Canada, is focused on uranium exploration and development in Saskatchewan’s Athabasca Basin and holds a 95% interest in the Wheeler River project, which hosts the Phoenix and Gryphon deposits, Reuters data showed. 3
Because Denison’s flagship asset is still being developed, investors tend to mark the stock to expectations for future production and financing, rather than current uranium sales.
Before Friday’s session, traders will watch whether DNN holds above its recent $2.61 low and whether it can retest Wednesday’s $2.68 intraday high.
Macro risk could also shape early-January positioning, with the Labor Department’s calendar showing the December employment report due on Jan. 9 and the December CPI report due on Jan. 13. 4
Denison’s investor calendar lists Nov. 6 as the reporting date for its most recent quarterly results and has not yet posted a date for the next update. 5
With markets reopening on Friday, investors are likely to take their cue from uranium pricing and sector headlines, while waiting for Denison’s next project and reporting milestones to set direction.
