Cameco Bets CA$116 Million on More Cigar Lake Uranium — But Can a 2.9-Point Stake Bump Justify the Rally?

Shares of Cameco Corporation surged as much as +2.3% to CA$167.92 on June 2, extending a blistering week-long run of nearly 13%, after the company announced it would deepen its ownership in one of the world's richest uranium mines. The deal lands at a moment when uranium stocks are outrunning the commodity itself — and investors must decide whether Cameco's premium price tag still makes sense.

• CA$116 Million Buys a Bigger Slice of the World's Highest-Grade Uranium Mine. Cameco and partner Orano agreed to acquire TEPCO Resources' entire 5% stake in the Cigar Lake Joint Venture, lifting Cameco's ownership by 2.871 percentage points to 57.418%.

Cameco's price tag is approximately CA$115.75 million (about US$84 million).

The mine holds an estimated 172.4 million pounds of uranium reserves as of year-end 2025 — meaning each additional percentage point of ownership backs roughly 5 million pounds of in-ground fuel. The cost looks modest for a company with a ~CA$49 billion market cap.

• Production Stays on Track, but the Stock Has Outrun the Commodity. Cameco's full 2026 production outlook remains at 19.5 million to 21.5 million pounds of uranium concentrate.

Meanwhile, the uranium spot price sat flat at US$83.35/lb as of June 1 , well below its 2023 highs. Uranium stocks are up roughly 40% over the past year even as the commodity price has been muted — a disconnect driven by forward-looking investors betting on structural supply deficits rather than today's spot market.

• The Nuclear Renaissance Gives Cameco a Bigger Story Than Mining Alone. Cameco's partnership with Brookfield and the U.S. government to deploy Westinghouse nuclear reactor technology is backed by at least US$80 billion in aggregate government investment.

Tech giants Meta and Microsoft have signed agreements for nuclear capacity to power AI data centers , creating a demand pipeline that barely existed two years ago.

• Valuation Raises the Bar for Execution. Cameco trades at roughly 75 times estimated 2027 earnings — territory normally reserved for high-growth tech firms. CIBC maintained an "Outperformer" rating with a CA$200 target , implying further upside, but given the stock's sharp rally, some analysts suggest new investors may prefer a more attractive entry point. The Cigar Lake deal is strategically sound but incremental; the real question is whether the nuclear supercycle Cameco is banking on arrives fast enough to backfill a valuation already priced for it.
