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.
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.
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.
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.
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.
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. Energy Fuels
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.
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.
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.
