Summary
Summary of the 8-K filed May 11, 2026. Cited figures are marked; the original filing is the authoritative source.
Constellation Energy (CEG) reported first-quarter 2026 results on May 11, 2026, with GAAP net income of $1,590 milliona, or $4.49 per diluted share, versus $118 million ($0.38) a year earlier.
Adjusted (non-GAAP) Operating Earnings rose to $972 millionb, or $2.74 per share, up from $2.14 in Q1 2025. The step-up is driven mainly by the Calpine acquisition, which closed in January 2026 and added about 26.5 TWh of gas, oil and renewables output in the quarter. Management reaffirmed full-year 2026 Adjusted Operating Earnings guidance of $11.00-$12.00 per share on 361 million expected average diluted shares.
The GAAP figure is inflated by a large $721 millionc after-tax unrealized fair-value gain on hedges, so investors should focus on the adjusted metric and on the balance sheet changes. The balance sheet changed materially. Total assets rose to $96.9 billion from $57.2 billion, goodwill jumped to $11.5 billion from $0.4 billion, and short-term borrowings reached $5.1 billion.
Long-term debt increased to $17.0 billiond from $7.3 billion, and assets held for sale rose to $5.7 billion. Operating cash flow was only $425 million in the quarter, held down by a $1.4 billion outflow in accounts payable and accrued expenses. Capital expenditures were $1.3 billion, and the company deployed about $335 million on share repurchases under a newly announced open-market program.
Management also highlighted a 380 MW CyrusOne data center agreement at Freestone and a 2029 Base EPS growth target of 20%+ from 2026 to 2029. The filing is a furnished (not filed) 8-K that includes the earnings release and an investor presentation.
It flags several items to watch: the pending divestiture of certain Calpine assets in the second half of 2026, the PJM Reliability Backstop Procurement process with a FERC filing expected around May 2026, and the company's expanded $5.0 billion share buyback authorization. Overall, the quarter shows strong adjusted earnings and reaffirmed guidance, offset by a much more leveraged balance sheet and weak quarterly operating cash flow.

03—Questions
Frequently Asked Questions
Why did GAAP EPS rise so sharply compared with last year?
GAAP EPS of $4.49 was lifted by a $721M after-tax unrealized gain on fair-value adjustments (hedges, swaps, and equity investments), which contributed about $2.03 per share. Adjusted Operating Earnings, which strip out these mark-to-market effects, are a more reliable gauge of underlying performance and rose to $2.74 from $2.14.
What drove the growth in adjusted operating earnings?
The main driver was the addition of Calpine's fleet following the January 2026 acquisition, which contributed 26.5 TWh of natural gas, oil and renewables output in the quarter. Stock-based compensation was favorable, and nuclear PTC and market conditions helped. These gains were partly offset by higher planned nuclear refueling outage days (99 vs. 88) and higher cost to serve load during Winter Storm Fern.
Is the company still on track for its 2026 guidance?
Yes. Management affirmed full-year 2026 Adjusted Operating Earnings guidance of $11.00-$12.00 per share. The company also projects Base EPS growth of 20%+ from 2026 through 2029, with additional upside from data center contracting, nuclear PPAs, and natural gas capacity.
What are the main balance sheet and cash flow concerns?
Total debt rose substantially: short-term borrowings reached $5.1B and long-term debt $17.0B, versus $1.7B and $7.3B at year-end 2025. Q1 operating cash flow was just $425M, reflecting a large working capital outflow, while capex was $1.3B. Investors should monitor deleveraging progress and the timing of the planned divestiture of certain Calpine assets in the second half of 2026.
What are the key growth catalysts investors should watch?
Key catalysts include the PJM Reliability Backstop Procurement process (FERC filing expected around May 2026, with bilateral contracting beginning around September 2026), potential data center deals on 'powered land' such as the 380 MW CyrusOne agreement at Freestone with an exclusive option on an additional 380 MW, and new nuclear PPAs and uprates. Management estimates each 1,000 MW of additional powered-land deals could add $0.20-$0.50 to EPS.
