Risk Factors

  • Nuclear PTC under IRA (starting Jan 1, 2024) subject to ongoing Treasury/IRS guidance that may reduce benefits; duration and value also exposed to legislative reversal
  • "Prohibiting Russian Uranium Imports Act" bans U.S. import of Russian low-enriched uranium, threatening nuclear fuel supply chain diversification across Constellation's large fleet
  • ~70% of generating resources concentrated in PJM market; proposed Trump administration/PJM framework for new load connections creates material market-design uncertainty
  • Calpine acquisition (Jan 2026) added significant goodwill to balance sheet; integration risk includes unknown liabilities, potential key-employee loss, and EPS dilution despite accretion expected in 2026
  • Credit facilities 26% European, 8% Canadian, 13% Asian banks — cross-border market disruption could impair liquidity access

Business Overview

  • Largest private-sector power producer globally post-Calpine merger (Jan 2026); 55 GW total capacity spanning nuclear, gas, geothermal, hydro, wind, solar
  • Calpine acquisition added ~23 GW across 72 assets, ~62 TWh retail load, ~2,500 employees; Calpine is nation's largest gas/geothermal generator
  • Three Mile Island restart (Crane Clean Energy Center, ~835 MW) backed by 20-year Microsoft PPA and $1.0B DOE loan guarantee issued Nov 2025
  • Nuclear fleet produced 183 TWh in 2025 at 94.7% capacity factor — ~4 percentage points above industry average annually since 2013
  • 15,339 total employees at Dec 31, 2025 (pre-Calpine); voluntary turnover only 3.3%, reflecting workforce stability at large-scale nuclear operator

Management Discussion & Analysis

  • Revenue $25.5B in 2025, up $1.97B (+8.3%) YoY; ERCOT best-performing segment at +22.8%, Other Power Regions weakest at +1.4%
  • GAAP net income fell to $2.32B from $3.75B (-$1.43B YoY); Adjusted (non-GAAP) Operating Earnings rose to $2.94B from $2.74B; operating income dropped to $3.09B from $4.35B, with effective tax rate surging to 33.8% vs 17.1%
  • Operating cash flow swung to +$4.24B from -$2.46B YoY; $1.08B net long-term debt redeemed in 2025; quarterly dividend held at $0.3878/share, raised to $0.4265 for Q1 2026
  • Capex guidance $5.7B (2026) and $4.7B (2027) inclusive of Calpine; ~29% allocated to nuclear fuel procurement; $3.9B earmarked for growth including Crane restart, nuclear uprates, and license renewals
  • Calpine acquisition ($22B, closed Jan 2026) adds ~23 GW and ~$12.6B assumed debt; PJM market reform and FERC co-location rulings cited as key emerging revenue risks
