Cameco and the uranium thesis — what the nuclear renaissance actually requires

The uranium thesis has been one of the most discussed investment ideas of the past four years. The spot price went from $29 per pound in 2021 to over $100 per pound in early 2024, pulled back, and has since stabilized in the $65 to $80 range. Cameco, the world's largest publicly traded uranium producer, went from a $15 stock in 2020 to over $60 at the peak.

The question now is not whether the thesis was right. It was right. The question is whether it is still right at current prices, and what the conditions are for it to remain right.

The demand side is structural

The demand case for uranium is the strongest it has been since the 1970s. Three forces are driving it simultaneously, and they are not cyclical.

The first is the global nuclear buildout. China has 28 reactors under construction and plans to add 6 to 8 per year through 2035. India has 7 under construction. South Korea is building new capacity. The United States is extending the life of existing reactors and, for the first time in decades, permitting new ones. The Vogtle units in Georgia came online in 2023 and 2024. Small modular reactors are moving from concept to project.

The second is the data centre electricity demand. The AI infrastructure buildout requires reliable, carbon-free baseload power. Natural gas is reliable but not carbon-free. Solar and wind are carbon-free but not reliable. Nuclear is both. Microsoft signed a 20-year power purchase agreement with Constellation Energy for power from the restarted Three Mile Island unit. Amazon, Google, and Meta are all pursuing nuclear power agreements. This is not speculative — the contracts are signed.

The third is the European reconsideration of nuclear. Germany's decision to shut down its last reactors in 2023 was a political decision, not an economic one, and it has not been reversed. But France, Belgium, the Netherlands, Sweden, and Finland have all either extended reactor life, approved new builds, or reversed planned shutdowns. The European energy crisis of 2022 changed the political calculus.

These three forces are structural. They do not reverse on a commodity price cycle.

The supply side is the variable

The demand story is clear. The supply story is where the thesis gets complicated.

Uranium supply is concentrated. Kazakhstan, through the state-owned Kazatomprom, produces approximately 45% of global primary uranium supply. Canada, through Cameco's McArthur River and Cigar Lake operations, produces approximately 15%. The rest is distributed across Namibia, Uzbekistan, Australia, and a handful of smaller producers.

The concentration in Kazakhstan is the key risk in the uranium thesis. In 2022, Kazatomprom announced production cuts due to supply chain constraints — specifically, shortages of sulfuric acid, which is used in the in-situ recovery process. Those cuts were genuine, and they contributed to the price spike. In 2024, Kazatomprom announced further production guidance reductions, citing continued supply chain issues and construction delays at new mines.

The question is whether those cuts are structural or temporary. If they are structural — if Kazakhstan's geology and supply chain constraints genuinely limit production growth — then the supply deficit is real and durable. If they are temporary — if Kazatomprom is managing production to support price, as OPEC manages oil production — then the supply deficit will resolve when the price is high enough to justify full production.

The desk's read is that the answer is somewhere between the two. Kazakhstan has genuine supply chain constraints that are not fully resolved. But Kazatomprom is also a state-owned enterprise that is aware of its market power and has demonstrated a willingness to manage production. The 2022 cuts were partly genuine and partly strategic. The 2024 cuts are similar.

This matters for the uranium price, and it matters for Cameco.

Cameco's position in the cycle

Cameco is the best-positioned uranium producer in the world for a sustained high-price environment. The reasons are structural.

McArthur River is the highest-grade uranium mine in the world, with average grades of approximately 7% U3O8 — roughly 100 times the global average. Cigar Lake is the second-highest-grade. The cost structure at both mines is among the lowest in the industry. Cameco's all-in sustaining cost is approximately $20 to $25 per pound of U3O8, against a current spot price of $65 to $80. The margin is real and durable.

The contracting book is the second structural advantage. Cameco has been systematically converting its uncontracted production into long-term contracts at prices well above the 2020 and 2021 lows. The company has disclosed that it has contracted approximately 220 million pounds of uranium for delivery through 2035, at prices that reflect the current market environment. This is not a company that is fully exposed to spot price volatility — it is a company that has locked in a significant portion of its revenue at attractive prices.

The Westinghouse acquisition, completed in 2023 in partnership with Brookfield Renewable, added a nuclear fuel services and reactor technology business to Cameco's portfolio. Westinghouse is the dominant supplier of nuclear fuel assemblies and reactor services to the global fleet of light-water reactors. The acquisition diversified Cameco's revenue stream beyond uranium mining and gave it exposure to the full nuclear fuel cycle.

What the thesis requires to stay right

The uranium thesis at current prices requires three conditions to be met.

The first is continued demand growth. The data centre buildout and the global reactor construction program must continue. The desk's view is that this condition is very likely to be met — the contracts are signed, the capital is committed, and the political momentum is in the right direction.

The second is supply discipline from Kazatomprom. If Kazakhstan returns to full production capacity and floods the market with uranium, the spot price will fall and the thesis will be impaired. The desk's view is that this risk is real but manageable — Kazatomprom has demonstrated that it is a rational actor that understands its market power, and the supply chain constraints in Kazakhstan are genuine enough to limit a rapid production ramp.

The third is Cameco's execution on its contracted delivery schedule. Cameco has committed to deliver uranium under its long-term contracts, and it must either produce that uranium or purchase it on the spot market. If production at McArthur River or Cigar Lake is disrupted — by flooding, by labour action, by regulatory delay — Cameco will be a forced buyer in the spot market at whatever price prevails. This happened in 2022, when Cameco was purchasing spot uranium to fulfill contracts while its mines were shut. The financial impact was manageable, but the operational risk is real.

The valuation question

Cameco trades at a premium to its historical valuation multiples. At $50 per share (approximately where it trades as of this writing), the stock is pricing in a uranium price of approximately $70 to $75 per pound over the long term, based on the desk's discounted cash flow analysis. That is not an unreasonable assumption — it is roughly where the long-term contract market is clearing today.

The upside scenario requires uranium prices to sustain above $80 per pound, which would be justified if the supply deficit is as large and as durable as the most bullish analysts believe. The downside scenario requires uranium prices to fall back toward $50 per pound, which would happen if Kazatomprom returns to full production and the demand growth is slower than expected.

The desk's base case is that the uranium price sustains in the $65 to $80 range for the next three to five years, which supports Cameco's current valuation. The stock is not cheap, but it is not expensive for a business with Cameco's cost structure, contracting book, and strategic position in the nuclear fuel cycle.

The desk's read

The desk owns Cameco. The position has been held since 2022, when the thesis was less consensus than it is today.

The current read is that the thesis is intact but the easy money has been made. The stock has moved from $15 to $50. The uranium price has moved from $29 to $65. The market now understands the demand story. The question is whether the supply story plays out as the bulls expect.

The desk's view is that it does — but with more volatility than the demand story alone would suggest. Kazatomprom is the wild card. The nuclear renaissance is real. The combination of the two means that uranium investing requires more active monitoring than most commodity investments, because the supply side can move quickly when a state-owned producer with 45% market share decides to change its production guidance.

Cameco is the right way to own the thesis. The position size should reflect the volatility of the supply side, not just the clarity of the demand side.

That is the uranium thesis in full. The demand is structural. The supply is the variable. Cameco is the best operator in the space. The valuation is fair but not cheap. The desk is long, and watching Kazakhstan.
