Evercore ISI reiterates Constellation Energy stock rating on strong Q1 beat

Constellation Energy reported Q1 2026 adjusted EPS of $2.74, ahead of the $2.59 consensus, and revenue of $11.12 billion versus $9.0 billion expected. Evercore ISI reiterated an Outperform rating and $380 price target, while management reaffirmed full-year guidance and projected base EPS growth of more than 20% from 2026 through 2029. The stock is highlighted as expensive at 39.8x P/E, but operational execution and earnings visibility remain strong.

Analysis

CEG is increasingly behaving less like a pure utility and more like a scarcity asset on the AI power bottleneck trade. The market is likely capitalizing in a long-duration option on nuclear-enabled baseload into a tightening grid, but that also means the equity is now sensitive to any sign that power pricing, not just unit growth, must do the heavy lifting to justify the multiple. With the stock already discounting years of execution, the next leg higher likely requires either another step-up in forward guidance or evidence that data-center offtake terms are materially better than investors currently assume.

The second-order winner is not just CEG, but any independent generator with dispatchable capacity and limited replacement risk; the loser is the buyer side of power if data-center load growth forces higher forward electricity costs. If CEG continues to re-rate, expect pressure on hyperscalers and colocators with less locked-in power supply, because the market will start treating power as a strategic input rather than an operating expense. That can ripple into broader infrastructure names through higher capex for grid interconnection, transmission, and backup generation.

The main risk is a valuation unwind if the market decides the current earnings visibility is already fully paid for. At nearly 40x earnings, the stock is vulnerable to a multiple compression regime if rates back up, merchant power prices normalize, or the Calpine-related earnings contribution proves less incremental than assumed. Near term, the catalyst path is earnings revisions and any announcements on long-term data-center contracts; over the next 6-18 months, the key variable is whether tightening power markets persist long enough to support upward estimate drift.

Consensus seems to be underestimating how crowded the "AI power shortage" theme has become, which is a double-edged sword: it supports fundamentals, but it also means positioning is likely extended and upside may arrive in bursts rather than smoothly. The better trade may not be outright long CEG here, but owning it against a weaker merchant or non-nuclear power name that lacks similar visibility. If the market starts to question whether power scarcity can be monetized fast enough, this becomes a high-beta de-rating candidate despite fundamentally strong operations.

Key Decisions for Investors

• Maintain a tactical long CEG, but only on pullbacks; prefer scaling in over 2-4 weeks rather than chasing momentum, because the stock is likely vulnerable to multiple compression after a strong run.
• Pair trade: long CEG / short a lower-quality merchant generator or unhedged utility with weaker data-center exposure for a 3-6 month relative-value expression on power scarcity.
• For those already long CEG, buy downside protection via 1-3 month put spreads financed against upside calls; the risk/reward is asymmetric given elevated valuation and event-driven volatility.
• Watch for any incremental data-center offtake announcements over the next 1-2 quarters; add only if contract tenor and pricing improve, since that would validate the higher multiple.
• If rates spike or the stock fails to hold post-earnings gains, reduce exposure quickly — the setup is high-conviction fundamentally but fragile at this valuation.
