Should You Buy Constellation Energy While It's Below $360?

AI-driven growth in data centers is escalating power demand and positioning Constellation Energy (CEG) as a strategic supplier: the company operates 14 nuclear stations (~22 GW) with a 94.6% average capacity factor, has a 20-year PPA with Meta for the 1,121 MW Clinton plant (relicensing and restart being expedited), is in advanced talks with other hyperscalers, and is expanding its footprint via a $27bn Calpine acquisition. Its reactors cleared the PJM 2026–27 capacity auction at the regional price cap—evidence of tightening supply—and analysts forecast adjusted EPS to nearly double by 2028 (~18% CAGR). The stock has pulled back about 19% from its peak and trades at a premium (~29.9x next-year EPS), leaving investors to weigh strong demand exposure and contract momentum against a rich valuation.

Analysis

Goldman Sachs projects global data-center power demand will rise ~50% by 2027 and up to 165% by decade-end, creating a direct demand tailwind for generators; Constellation Energy (CEG) has positioned itself as a core supplier by securing a 20-year PPA with Meta for the full output of the 1,121 MW Clinton nuclear plant, expediting relicensing and restart, and reporting management commentary that additional hyperscaler deals are “quite close.” Constellation operates 14 nuclear stations totaling roughly 22 GW and delivered a 94.6% average nuclear capacity factor over the past three years (≈4 percentage points above prior industry comparisons), which supports higher revenue per reactor during peak demand. The company cleared the PJM 2026–27 capacity auction at the regional price cap—evidence of tightening supply margins—and analysts model adjusted EPS to nearly double from 2024 to 2028 (≈18% CAGR). CEG has expanded scope via a $27 billion Calpine acquisition expected to close in Q4, yet the stock has retraced ~19% from a $412 peak to below $360 and still trades at a premium of ~29.9x next-year EPS (from 35.7), leaving upside linked to deal execution, PPA pipeline conversion, and sustained capacity prices while valuation and integration risk remain key constraints.

Key Decisions for Investors

• Consider a phased, size-limited accumulation of CEG on further pullbacks to capture exposure to durable AI-driven data-center demand and secured hyperscaler PPAs, while avoiding full-sized entries given the near-30x forward multiple
• Monitor two near-term catalysts closely—announcement of additional hyperscaler PPAs (management expects another before the late-February earnings call) and confirmation of the $27bn Calpine close in Q4—and increase conviction only if both are delivered on schedule
• Use PJM capacity-auction results and forward power/merchant revenue guidance as leading indicators; if auction prices or analyst EPS trajectories deteriorate, consider trimming or hedging exposure to reduce valuation risk
