Summary
Summary of the 8-K filed February 24, 2026. Cited figures are marked; the original filing is the authoritative source.
Constellation Energy (CEG) reported fourth-quarter and full-year 2025 results on February 24, 2026.
GAAP net income attributable to common shareholders was $1.38a per share for Q4 2025 (down from $2.71 in Q4 2024), and $7.40 per share for full-year 2025 (down from $11.89 in 2024). Adjusted (non-GAAP) Operating Earnings were $2.30 per share for Q4 2025 (down from $2.44) and $9.39 per share for full-year 2025 (up from $8.67). Management noted that full-year adjusted earnings exceeded the midpoint of guidance for the fourth consecutive year.
The GAAP decline was driven largely by unrealized fair value losses on hedges and related items, while the adjusted increase reflected favorable market and portfolio conditions, higher Illinois banked ZEC revenues, and favorable nuclear outages, partly offset by unfavorable nuclear PTC portfolio results. The most significant strategic development is the completion of the Calpine Corporation acquisition on January 7, 2026, which the company says creates the nation's largest electricity producer and adds natural gas and geothermal generation to its nuclear fleet. Balance sheet changes reflect this expansion: total assets rose to $57.2 billionb from $52.9 billion, and short-term borrowings reached $1.65 billion versus zero a year earlier.
Full-year operating cash flow improved to $4.2 billionc from negative $2.5 billion, though the prior-year figure was distorted by a large deferred payment item. Other catalysts include new 380 MW data center supply agreements with CyrusOne at the Freestone Energy Center (with a further 380 MW Phase 2 exclusivity), NRC approval of license renewals for Clinton and Dresden, and a $1 billion DOE loan guarantee supporting the Crane restart. Investors should note that 2026 guidance was not provided in this release and will be discussed on the March 31, 2026 Business and Earnings Outlook call.
The quarterly dividend was declared at $0.4265d per share, and management expects to grow the dividend per share by roughly 10% in 2026 following a 10% increase in the annual dividend. Key items to monitor include the integration and financial contribution of Calpine, the pace of data center contracting, Crane restart approvals, and the volatility of GAAP earnings driven by mark-to-market accounting.

03—Questions
Frequently Asked Questions
Why did GAAP earnings decline while adjusted operating earnings increased in 2025?
GAAP net income per share fell to $7.40 from $11.89 mainly because of unrealized fair value losses on economic hedges, interest rate swaps, and related items, as well as changes in nuclear decommissioning-related activities. Adjusted operating earnings exclude these mark-to-market and decommissioning effects. On that basis, EPS rose to $9.39 from $8.67 on favorable market and portfolio conditions, higher Illinois banked ZEC revenues, and favorable nuclear outages, partly offset by unfavorable nuclear PTC portfolio results.
What does the Calpine acquisition mean for Constellation's business and financials?
The Calpine acquisition, completed January 7, 2026, adds a large natural gas, oil, renewables and geothermal fleet to Constellation's nuclear base and strengthens its commercial and retail platform. The balance sheet already reflects some of the change, with total assets at $57.2 billion and $1.65 billion of short-term borrowings at year-end 2025. The release does not quantify Calpine's full-year contribution, which investors should expect to see in 2026 guidance and subsequent filings.
What growth opportunities did the company highlight?
The main growth drivers cited are data center power demand and license extensions for nuclear assets. Calpine's Freestone Energy Center will supply a new 380 MW CyrusOne data center, with an exclusive option for a second 380 MW phase, and Thad Hill has a separate 400 MW agreement. The Crane restart is supported by a 20-year Microsoft PPA, though it remains subject to NRC and state and local approvals.
What is the dividend outlook, and when will 2026 guidance be provided?
The board declared a quarterly dividend of $0.4265 per share, payable March 20, 2026, to holders of record on March 9, 2026. Management said it expects to grow the per-share dividend by another 10% in 2026, following a 10% increase in the annual dividend. Detailed 2026 earnings guidance and the longer-term strategy will be presented on the March 31, 2026 Business and Earnings Outlook call at 8 a.m. Eastern.
