TORONTO, March 16, 2026, 12:55 EDT
Denison Mines Corp.’s U.S.-listed stock slid 6.3% to $3.58 as of 12:39 p.m. EDT, despite a lift in both Wall Street and Toronto equities on softer oil. The shares kicked off at $3.84, with volume topping 19 million at that point.
The decline stings for a company eager to shed its image as just a uranium developer. Denison still plans to kick off site prep and construction at its Phoenix project in Saskatchewan this March, aiming for first output in mid-2028. That timeline would put Phoenix among the rare, significant new uranium plays expected before decade’s end.
The timing is key here: uranium supply’s grown tighter lately. Back in January, Reuters flagged U.S. uranium consumption outpacing what’s coming out of domestic mines, with long-term contracts approaching $100 a pound. Denison just added last week that uranium market negotiations have been driving those long-term prices even higher.
Denison posted its 2025 results last week, sticking with its final investment decision for the Phoenix project. CEO David Cates said Denison is “ready to commence site preparation” before the month is out, citing completed approvals, procurement, engineering, and financing. Denison Mines Corp.
The federal go-ahead landed in February, when the Canadian Nuclear Safety Commission signed off on both the environmental assessment and the construction licence for Wheeler River. Cates described it as a “landmark achievement.” According to the company, Phoenix now stands as Canada’s first uranium project to secure approval for in-situ recovery (ISR)—a process that injects solution into ore, dissolves the uranium, then pumps it up to the surface—and also marks the first major uranium development in the country to get construction clearance in over two decades. Denison Mines Corp.
Denison maintains it has the resources to get the project off the ground, despite the hefty price tag. Back in January, the company pegged post-FID initial capital for Phoenix at roughly C$600 million—about 20% higher than the 2023 feasibility study after factoring in inflation. As of September 30, Denison reported more than C$700 million in cash, physical uranium, and investments. The company also flagged its US$345 million convertible note deal from August, saying that supports development spending.
The drop on Monday outpaced declines seen in a few rivals. NexGen Energy, which trades in the U.S., slipped 4.2%. Cameco managed a slight 0.2% gain. Traders, it seems, weren’t pulling out of uranium stocks across the board.
LSEG figures cited by Reuters put Denison’s 2025 revenue at $4.9 million, with a net loss hitting $217.3 million. That’s left shares tethered closely to how Phoenix performs and whether uranium prices stay elevated during the buildout.
The road ahead looks tougher. In January, Denison raised its Phoenix project cost estimate, citing inflation and tweaks to the plan. The company also flagged that once construction gets underway, real-world conditions could push costs and timelines away from current technical studies and forecasts.
With permits in hand, investors have shifted focus to mobilization. According to the company, most contract awards wrapped up in January. That puts the spotlight on Denison stock: can the roughly two-year build-out actually stay on track and hit the mid-2028 production goal?
