Constellation Energy Posts 23% Revenue Jump as Nuclear Outpaces Gas on Reliability
Constellation's second-quarter earnings and Cameco's contracted uranium position illustrate two distinct bets driving US nuclear investment.
Constellation Energy shares rose 1.39% on Monday (2026-08-17) after the company reported $7.5 billion in second-quarter revenue, up 22.9% from a year earlier, with adjusted earnings per share of $2.55, a 33.5% annual gain. The uranium ETF URA edged 0.27% higher to $44.93 on the same session. NYMEX Henry Hub front-month slipped 0.38% to $2.65 per MMBtu on Monday (2026-08-17). Cheaper gas has not dented nuclear equity demand.5
Nuclear's competitive position rests on output consistency. US Department of Energy data show nuclear plants operate at a capacity factor of around 92%, roughly 1.5 times higher than natural gas generation and four times that of solar. Nuclear also supplies 47% of US zero-carbon electricity, more than wind and solar combined as of 2023. Microsoft and Meta have each signed 20-year power purchase agreements directly with nuclear operators, paying for guaranteed baseload supply rather than intermittent clean megawatts.4,3,2
The fuel supply side of the trade runs through Cameco. The Canadian miner holds 433 million pounds of proven and probable uranium reserves in Saskatchewan's Athabasca Basin, concentrated at Cigar Lake, which the company describes as the world's highest-grade and lowest-cost deposit. Cameco has 28 million pounds of annual uranium sales contracted through 2030. That structure limits volume downside but also caps how much of any spot uranium rally flows directly to earnings.5
Western governments' concern over Russian enrichment capacity has reshaped how Cameco selects counterparties and frames its supply offering. The company positions itself explicitly as a supplier of dependable uranium to Western nations. In March 2026, Cameco signed a $2.6 billion agreement with India's Department of Atomic Energy to deliver 22 million pounds of uranium ore concentrate through 2035, adding India's state nuclear agency alongside its existing Western customer base.3
Cameco is no longer a pure mining play. Through a 49% joint venture stake in Westinghouse Electric Company, with Brookfield Renewable Partners controlling the remaining 51%, Cameco holds a share of reactor services revenue largely decoupled from the spot uranium price. Westinghouse technology operates in roughly 57% of reactors worldwide, generating recurring income from maintenance, refuelling cycles, software, and replacement parts.5,4
The US government has provided financing support for new builds. The Department of Energy conditionally committed $17.5 billion in loan facilities to finance up to 10 Westinghouse AP1000 reactors. Each AP1000 that reaches commissioning would extend Westinghouse's future service backlog, which flows partly to Cameco through the JV structure.3,4
FERC projections show 86 gigawatts of solar additions over the next three years, enough to push solar past coal in the US generation stack. But solar's capacity factor is roughly a quarter of nuclear's. That gap keeps demand for dispatchable baseload intact even as solar additions accelerate, and nuclear operators are capturing it through long-term contracts rather than competing on spot power prices.1
Cameco shares have pulled back 36% from their 52-week high. The contracted volume position limits near-term earnings risk, but the pricing terms embedded in those contracts are not disclosed in enough detail for outside analysts to assess how much of a uranium price rally actually reaches reported earnings.3
The more immediate signal is whether Westinghouse's AP1000 programme draws down on the DOE's $17.5 billion conditional commitment fast enough to move Cameco's JV earnings over the next two to three years. Constellation, running its existing fleet, is already booking the revenue. Cameco and Westinghouse are waiting for new-build timelines to firm. Post-2030 contract renewal terms are where the bull case either gets confirmed or stalls.3,4,5
