Sources: Total operating revenues, GAAP net income and non-GAAP adjusted operating earnings are from Constellation Energy's Q4/full-year 2025 earnings release (Feb. 2026). Revenue by region reflects Constellation's segment disclosure (Mid-Atlantic, Midwest, Other Power Regions, New York, ERCOT, plus an Unallocated category covering corporate, trading and hedging activity not assigned to a generation region), as compiled by MarketScreener from the company's FY2025 filings; slices sum to about $25.52 billion, roughly $13 million (0.05%) below the $25.533 billion reported total due to rounding. FY2021 revenue reflects Constellation's carve-out financial statements prior to its February 2022 spin-off from Exelon. Nuclear capacity and its estimated share of total U.S. nuclear capacity are third-party estimates (The Motley Fool, citing company and EIA-comparable data); no independent third-party estimate of Constellation's overall electricity market share was found and none is forced here.
