Constellation Energy Corp Dossier
Qualitative Analysis
Business overview
Constellation Energy Corporation (NASDAQ: CEG) is the largest producer of carbon-free energy and the leading supplier of clean energy and sustainable solutions in the United States. Headquartered in Baltimore, Maryland, the company operates a massive, highly reliable generation fleet with approximately 31,676 megawatts of capacity. This fleet is anchored by the nation's largest nuclear power portfolio, alongside wind, solar, hydroelectric, and dispatchable natural gas assets. Constellation serves a diverse customer base, including distribution utilities, municipalities, cooperatives, and commercial, industrial, and residential clients across multiple geographic regions. The company is uniquely positioned at the intersection of rising clean energy demand and the structural shift toward high-capacity, always-on electricity required by artificial intelligence and hyperscale data centers.

Strategic Initiatives
Growth programs, investments, and their expected impact
Integrate Calpine's natural-gas, geothermal and commercial operations with Constellation's nuclear fleet and customer platform, creating a 55 GW portfolio serving approximately 2.5 million customer accounts.
Expected impact: At announcement, Constellation projected more than 20% adjusted operating EPS accretion in 2026, at least $2 per share of accretion in later years and more than $2 billion of additional annual free cash flow.
Restore the former Three Mile Island Unit 1 as the Crane Clean Energy Center and return approximately 835 MW of emissions-free nuclear generation to the PJM grid under a 20-year Microsoft PPA.
Expected impact: The project is expected to restore firm nuclear capacity, support approximately 3,400 direct and indirect jobs and add more than $16 billion to Pennsylvania GDP over its operating period.
Extend nuclear operating lives, increase output through uprates and secure long-duration PPAs. Recent actions include 920 MW of additional contracts, a Walmart-supported 30 MW Dresden uprate and license-renewal applications for Ginna and Nine Mile Point Unit 1.
Expected impact: The program can add incremental generation without constructing equivalent new plants, improve contracted revenue visibility and preserve strategically important firm capacity.

Recent deals and strategic collaborations
Recent Acquisitions
Combine Constellation's nuclear fleet with Calpine's natural-gas and geothermal generation and commercial platform, expanding geographic coverage, dispatchable capacity and the range of energy products available to customers.
Financial impact: At announcement, management projected more than 20% adjusted operating EPS accretion in 2026, at least $2 per share of accretion in future years and more than $2 billion of additional annual free cash flow.
Strategic Partnerships
Provides long-term contracted demand for approximately 835 MW of restored emissions-free nuclear generation and underpins the targeted 2027 restart.
The agreement covers 1,121 MW beginning in June 2027, supports continued Clinton operations after Illinois ZEC support expires and enables a 30 MW uprate.
The Freestone agreement covers 380 MW and includes exclusivity for another 380 MW phase, supplementing 400 MW of earlier Thad Hill agreements and positioning Constellation to serve large AI and data-center loads.
Walmart will purchase approximately 176 MW through two 15-year terms beginning in 2029 and 2030; the agreement supports a 30 MW Dresden uprate and Walmart's Illinois expansion.
Constellation acquired a minority interest in five operating facilities producing approximately 1.5 million MMBtu annually and established a framework for approximately 3.0 million MMBtu of additional annual production.
