Exelon Corporation

Overview

Exelon is the largest regulated electric and gas utility holding company in the United States by customer count, serving approximately 10.7 million customers across six operating utilities with about 20,000 employees. It is a pure-play transmission and distribution utility that owns no generation assets. Power generation was separated in February 2022, when Exelon spun off its nuclear fleet as an independent public company, Constellation Energy.

CEO Calvin Butler has led Exelon since 2022. The six utilities span the Mid-Atlantic corridor and northern Illinois: Commonwealth Edison in Illinois, PECO in southeastern Pennsylvania, Baltimore Gas and Electric in Maryland, Pepco in Washington D.C. and suburban Maryland, Delmarva Power in Delaware and parts of Maryland, and Atlantic City Electric in New Jersey.

The geography is consequential. Exelon's territory covers some of the densest data center corridors in the country, particularly Northern Virginia and the Maryland suburbs of D.C., which gives it exposure to one of the highest-growth electricity demand stories of the decade.

The six utilities

Financial performance

Exelon reported adjusted operating EPS of $2.77 for FY2025, above its $2.64 to $2.74 guidance range and up from $2.50 in FY2024, and guided to $2.81 to $2.91 for 2026. Revenue of roughly $24.2 billion reflects regulated utility billing across the six utilities, with the largest share from ComEd and PECO. The company targets adjusted operating EPS growth near the top of its 5% to 7% range through 2029. Because Exelon operates entirely within regulated frameworks, revenue and earnings are driven by approved rates, capital investment levels, and weather-normalized demand. It pays a quarterly dividend of $0.42 per share, about $1.68 annualized, at a roughly 60% payout ratio.

Exelon has raised its capital program sharply. The four-year plan now runs to roughly $41.7 billion for 2026 through 2029, about $10 billion a year, supporting expected rate base growth of 7.9%. It is increasingly weighted toward transmission, much of it tied to data-center load, with transmission rate base projected to grow around 16% through 2029. That growth supports the long-term EPS trajectory: as more capital enters rate base, regulated returns compound. Exelon plans to fund the program with a balanced mix that includes about $3.4 billion of equity over the four years.

Grid investment & data center demand

Exelon's largest growth opportunity is the data center and AI infrastructure buildout concentrated in its service territory. Northern Virginia, the largest data center market in the world, sits primarily in Dominion Energy's territory, and the adjacent Maryland, D.C., and Delaware markets served by Pepco, BGE, and Delmarva are seeing meaningful large-load interconnection requests as hyperscalers expand beyond saturated Northern Virginia.

ComEd's Chicago territory is drawing data center interest as operators look for lower-cost land and power; large load there has climbed from under 100 megawatts in 2015 to roughly 600 megawatts in 2025. Across its utilities Exelon reports a high-confidence large-load pipeline of about 18 gigawatts, with roughly 43 gigawatts of total interconnection requests under study or preparing for it. That demand is turning net load growth positive, to about 3.1% over the four-year plan after years of flat-to-declining usage, and is driving a transmission-led increase in capital spending, including a transmission service agreement with Amazon in Pennsylvania. Unlike a generator, Exelon earns regulated returns on the transmission and distribution infrastructure regardless of which generator supplies the power.

Regulatory environment

Exelon operates across five state regulatory jurisdictions, Illinois, Pennsylvania, Maryland, Delaware, and New Jersey, plus the District of Columbia, each with its own public utility commission, rate case process, and policy priorities. Managing six regulators at once is a core organizational competency and a source of earnings risk: an unfavorable rate case outcome in any large jurisdiction moves earnings meaningfully.

Illinois is the most complex relationship. ComEd's 2020 deferred prosecution agreement, arising from a federal investigation into lobbying payments made to associates of former Illinois House Speaker Michael Madigan, required a $200 million payment and compliance reforms. The criminal chapter closed in 2025: Madigan was convicted on bribery and related counts and sentenced to seven and a half years in prison, with the conviction later upheld on appeal. The political damage complicated ComEd's rate cases in Springfield for several years. The relationship has since stabilized, and Illinois remains a closely watched jurisdiction.

Relationship with Constellation Energy

Constellation Energy was Exelon's nuclear generation subsidiary until February 2022, when Exelon distributed Constellation shares to its shareholders and the two companies became independent. Constellation operates the largest nuclear fleet in the United States, and after closing its acquisition of Calpinein January 2026 it became the country's largest power producer, a combined gas-and-nuclear generator of roughly 55 gigawatts rather than the nuclear-only company it was at separation.

The separation rested on the view that a pure-play T&D utility and a pure-play power generator each command better valuations standing alone, and that Exelon's utilities were carrying a conglomerate discount while bundled with nuclear assets. The two companies remain connected through power purchase agreements and the geography of their operations, with separate boards, management teams, and capital structures.

Key considerations

Multi-state regulatory complexity is the persistent operational challenge. Rate cases across six jurisdictions run on overlapping timelines, and an unfavorable outcome in Illinois or Maryland, the two largest, compresses near-term EPS. The multi-year capital commitment requires sustained regulatory support across several political environments at once.

Interest rate sensitivity is real. Exelon finances a large capital program with debt, and rising borrowing costs raise the cost of that program and can pressure the allowed returns regulators set in rate cases. The long-term EPS growth target assumes supportive rate outcomes and manageable financing costs.

The upside is load growth. If demand from data centers and electrification exceeds current projections, the capital program grows and regulated returns on that capital compound directly into earnings. As the T&D owner serving some of the most electricity-intensive corridors in the country, Exelon captures that growth regardless of which generator supplies the power, which is the core of the investment case and the main exposure if the load fails to arrive.
