▲ Business & latest quarter
Constellation's Q1 2026 results (mid-May 2026) showed GAAP EPS of $4.49 (versus $0.38 a year earlier) and adjusted operating EPS of $2.74, up 28% year-over-year, beating estimates. Full-year 2026 adjusted operating EPS guidance of $11-12 was reaffirmed. The nuclear fleet — the largest in the US — ran at a 92.3% capacity factor, generating 40 terawatt-hours in the quarter, with roughly 147 TWh of annual capacity available, ~93% of it within the PJM grid footprint that serves much of the US mid-Atlantic. The $26.6 billion Calpine acquisition closed in January 2026, adding gas, geothermal, hydro, wind, and solar assets to reach a combined ~55 gigawatts of generation capacity. The company holds over 5,650 megawatts of long-term clean power agreements with data center and hyperscale customers, including a 20-year power purchase agreement with Microsoft tied to the Crane Clean Energy Center (the former Three Mile Island Unit 1), whose restart is targeted around 2027-2028 pending regulatory sign-off.
● Why it's in the book
Constellation is a way to own the AI buildout's power constraint rather than the compute layer directly — a theme that's structurally uncorrelated with chip-sector sentiment. Firm, carbon-free nuclear capacity is the specific asset hyperscalers are contracting for at premium long-term rates, and Constellation controls more of it than any other US operator.
■ Risks to watch
The stock trades at a rich premium (around 40x earnings) that assumes continued conversion of its available nuclear capacity into new long-term contracts — the market has been watching for confirmation of new hyperscaler deals since a December 2025 FERC order cleared a key regulatory bottleneck for co-located data center service. Calpine integration (2,300 employees, 60+ power plants) is still in its early stages and carries execution risk. Nuclear fleet aging, relicensing, and maintenance costs are longer-duration risks to monitor.
