Citi downgrades Constellation Energy stock rating after Meta deal

Citi downgraded Constellation Energy (CEG) to Neutral from Buy, citing a substantial 40% year-to-date stock rally and a 55% increase over the past year which has pushed its market capitalization to $98 billion. The downgrade follows the announcement of a power purchase agreement with Meta Platforms and reflects an updated valuation approach considering potential datacenter deals for Constellation's nuclear plants. While Citi raised its price target to $318 from $232, other firms like UBS and BMO Capital Markets have increased their price targets as well, maintaining Buy/Outperform ratings, driven by the Meta agreement and potential upside from the Calpine transaction.

Analysis

Constellation Energy (CEG) has experienced a significant stock price appreciation, surging 40% year-to-date and 55% over the past year, reaching a market capitalization of $98 billion. This rally prompted Citi analysts to downgrade CEG from Buy to Neutral, citing valuation concerns despite raising their price target to $318 from $232. Citi's revised valuation incorporates the potential for CEG's nuclear plants, particularly the 70% of its 22-gigawatt fleet with licenses expiring before 2045, to secure datacenter deals at approximately $80 per megawatt-hour, and a higher enterprise value to EBITDA multiple for existing plants due to increased scarcity. The stock currently trades at a P/E ratio of 31x and an EV/EBITDA multiple of 16x. Despite Citi's downgrade, CEG reported robust Q1 2025 adjusted operating earnings of $2.14 per share, an increase of $0.32 year-over-year, and reaffirmed its full-year EPS guidance of $8.9 to $9.6 per share. A key positive development is the 20-year power purchase agreement with Meta Platforms for nuclear energy from the Clinton Clean Energy Center, which is expected to add $19 per share in value according to UBS and ensures the facility's continued operation, preserving 1,100 jobs and generating $13.5 million in annual local tax revenue. This deal, along with potential upside from the Calpine transaction and strategic focus on long-term carbon-free energy contracts, has led other analysts, such as UBS (target $360, maintained Buy) and BMO Capital Markets (target $337, maintained Outperform), to remain bullish, contrasting with Citi's more cautious stance. The broader analyst community maintains a Strong Buy consensus with price targets ranging from $184 to $385.

Key Decisions for Investors

• Given Constellation Energy's substantial stock appreciation and Citi's downgrade to Neutral on valuation grounds, investors should carefully assess their positions and risk tolerance, particularly after the 40% year-to-date rally.
• Despite near-term valuation concerns highlighted by Citi, the company's strong Q1 earnings, reaffirmed guidance, and strategic PPA with Meta Platforms for nuclear energy underscore robust long-term growth drivers; thus, longer-horizon investors might consider maintaining exposure or looking for entry points on price weakness.
• Investors should closely monitor CEG's ability to secure additional long-term datacenter contracts at favorable rates, progress on the Calpine transaction, and developments in advanced nuclear reactor technology, as these are key catalysts for future performance.
• The divergence in analyst ratings and price targets suggests that while the underlying business fundamentals tied to clean energy and data center demand are strong, the current stock valuation (P/E 31x, EV/EBITDA 16x) warrants a thorough evaluation of the risk/reward profile.
