NEW YORK, December 31, 2025, 07:46 ET — Premarket
Denison Mines Corp (DNN) was unchanged at $2.63 in premarket trading on Wednesday, data from Public.com showed as of 5 a.m. ET. 1
The muted start comes ahead of the final U.S. equity session of 2025. Stocks trade regular hours on New Year’s Eve before markets close for the Jan. 1 holiday, a Barron’s report said. 2
Denison ended Tuesday down 2.6% at $2.63 after trading between $2.62 and $2.74, with about 31.8 million shares changing hands, StockAnalysis.com data showed. 3
Uranium pricing has been softer at the margin. Spot uranium fell to $81.85 per pound on Dec. 30, down 0.12% on the day, Trading Economics data showed. 4
Uranium-linked equities were also lower in early indications. The Global X Uranium ETF, an exchange-traded fund that holds a basket of uranium miners, was down about 0.6% in premarket quotes, MarketWatch data showed. 5
In the sector, Energy Fuels said on Monday it exceeded 2025 uranium production and sales guidance and signed two new long-term uranium sales contracts with U.S. nuclear utilities for deliveries spanning 2027 to 2032. “Strong uranium production is critical to America’s economic and national security,” CEO Mark S. Chalmers said. 6
Denison, based in Toronto, is developing the Wheeler River project in Canada’s Athabasca Basin and plans to mine the Phoenix deposit using in-situ recovery (ISR) — extracting uranium by circulating solution through wells instead of digging a conventional mine. In November, the company said it expects a Canadian Nuclear Safety Commission decision on key environmental and construction approvals in early 2026 and that total engineering for Phoenix was about 85% complete, with nearly $720 million in cash, investments and uranium holdings on hand. 7
A regulator decision would give investors a firmer timeline for a final investment decision and construction spending, the milestones that often drive valuation for pre-production uranium developers. A delay would keep the stock trading more like a proxy for uranium prices and broader risk appetite.
The next scheduled checkpoint is Denison’s quarterly report, expected on Feb. 26, 2026, according to TipRanks.
The year-end calendar can also distort moves across markets. SIFMA, which publishes a holiday schedule for U.S. fixed-income markets, lists an early close at 2 p.m. ET on Wednesday. 8
Traders typically treat small premarket moves with caution because extended-hours trading can have wider bid-ask spreads and thinner liquidity. Confirmation usually shows up after the open in volume and follow-through.
