Why Is Constellation Energy Stock Falling Tuesday?

Constellation Energy Corp. (NASDAQ:CEG) shares fell Tuesday, underperforming a rising broader market, after investors reacted to weaker-than-expected 2026 guidance and the lack of new data center deals at a closely watched investor update. Constellation Energy also outlined its 2026 outlook, emphasizing nuclear-led generation, long-term contracting, and disciplined capacity expansion as core growth drivers. EPS Outlook And Capital Allocation Constellation Energy initiated 2026 adjusted operating earnings guidance of $11.00 to $12.00 per share, versus an estimate of $11.92, reinforcing a strong multi-year earnings growth trajectory. The company expects base EPS to grow more than 20% from 2026 to 2029 and targets long-term rolling three-year base EPS growth above 10%. This outlook excludes potential upside from capturing premium value on 147 million MWh of nuclear generation and additional natural gas contracts. Constellation also expanded its capital allocation strategy, increasing its share buyback authorization to $5.0 billion. The company plans to invest $3.9 billion in growth capital across natural gas, storage capacity, and nuclear uprates. Nuclear Performance And Capacity Expansion The company said its nuclear fleet continues to outperform industry benchmarks, delivering capacity factors about 4% higher and producing more than 180 million MWh annually. That output generates over 8 million additional MWhs, enough to power roughly 6.6 million homes. Constellation also detailed plans to add or extend approximately 9,350 megawatts of capacity through nuclear uprates, restarts, renewables, storage, and new gas projects. Long-Term Contracting And Commercial Strategy The company is securing long-term, premium-priced contracts across utilities, corporations, and data centers, using its nuclear fleet as a foundation for a reliable, clean energy supply. It is also pairing nuclear with gas and renewable solutions. Constellation has already locked in more than 5,650 MW of long-term clean energy agreements, spanning nuclear, geothermal, battery storage, and data center-related deals. Financial Position And Portfolio Strength Constellation maintained investment-grade ratings of BBB+ and Baa1 following the Calpine acquisition and issued $2.75 billion in senior notes in early 2026, including long-dated debt. The company is also diversifying nuclear fuel sourcing through long-term agreements extending into the 2030s to manage supply and pricing risks. Constellation operates more than 22,000 MW of nuclear capacity and over 4,000 MW of renewables, positioning it as a major provider of firm, carbon-free power across U.S. markets.
