Exelon Corporation (EXC) Business & Investor Dossier

Exelon makes money as a regulated electric and gas distribution utility through six operating companies serving approximately 10 million customers: ComEd (Northern Illinois, including Chicago), PECO (Southeastern Pennsylvania, including Philadelphia), BGE (Central Maryland, including Baltimore), Pepco (Washington D.C. and Maryland suburbs), Delmarva Power (Delmarva Peninsula of Maryland and Delaware), and Atlantic City Electric (South New Jersey). Each subsidiary operates under state or district utility regulation, earning a allowed return on its invested rate base. Distribution of electricity is the primary revenue driver, with gas distribution a smaller component at several subsidiaries. Exelon does not generate electricity for its distribution customers -- electricity supply is purchased in wholesale markets and passed through to customers at cost, while Exelon earns only the distribution and transmission wires charges.

Exelon spun off its competitive power generation and energy marketing business as Constellation Energy (CEG) in February 2022 to create two focused, pure-play companies. Before the spin-off, Exelon was a complex integrated utility combining regulated distribution (predictable, stable earnings) with competitive nuclear generation and retail energy supply (volatile, market-driven earnings). The combination made valuation difficult for investors and created competing capital allocation priorities. Management and investors believed that a pure regulated utility (Exelon) would trade at a higher multiple because of its predictable earnings and dividend growth profile, while a pure competitive nuclear and retail energy company (Constellation) could pursue a different strategy more aggressively. Constellation retained the nuclear power fleet -- one of the largest in the U.S. -- which became extremely valuable as electricity prices rose and nuclear's carbon-free status gained market support. Both companies have performed well as independent entities since the separation.

ComEd (Commonwealth Edison) is Exelon's largest subsidiary, serving approximately 4 million electric customers in Northern Illinois including the Chicago metropolitan area. ComEd represents roughly 40% of Exelon's total rate base and earnings. Chicago and its suburbs constitute one of the most economically important utility service territories in the United States, with large industrial, commercial, and residential load. ComEd has been at the center of regulatory controversy in Illinois: the ComEd Four scandal involved ComEd admitting that it made payments to associates of former Illinois House Speaker Michael Madigan in exchange for favorable legislation, resulting in a deferred prosecution agreement in 2020 and significant fines. The scandal damaged Exelon's reputation and led to management changes. Despite the regulatory friction, ComEd's rate base continues to grow through grid modernization investments and Illinois has been generally supportive of reliability and clean energy investments through formula rate mechanisms.

Exelon's six-utility structure spans a diverse set of regulatory jurisdictions and geographies: Illinois, Pennsylvania, Maryland, Washington D.C., Delaware, and New Jersey. This diversification is both a strength and a complexity. No single regulatory outcome or regional economic downturn can devastate the whole company. However, managing six separate utility regulatory relationships adds administrative complexity, requires compliance with each jurisdiction's specific rules, and can dilute management attention. The territories span densely populated urban cores (Chicago, Philadelphia, Baltimore, Washington D.C.) and suburban and semi-rural areas on the Delmarva Peninsula and South New Jersey. The Mid-Atlantic and D.C.-area utilities (BGE, Pepco, Delmarva, ACE) were acquired in 2012 through the $7.9 billion acquisition of Constellation Energy's utility holding company and the Pepco Holdings acquisition in 2016, substantially expanding Exelon's regulated footprint beyond Illinois and Pennsylvania.

Exelon's main risks include: regulatory risk across six utility jurisdictions that must each approve rate increases and capital recovery -- an adverse regulatory decision in any subsidiary can reduce earnings; storm and weather risk since the East Coast and Midwest geographies experience hurricanes, nor'easters, blizzards, and summer storms that damage infrastructure; interest rate sensitivity typical of capital-intensive regulated utilities; political and regulatory reputation risk from the ComEd corruption investigation; execution risk on large-scale grid modernization programs that involve significant capital spending; and customer affordability concerns in low-income service territories (Baltimore, Philadelphia, South New Jersey) where high electricity rates are a political issue. The long-term regulatory trajectory is generally favorable for distribution utilities like Exelon as electrification of transportation and buildings expands load and justifies grid investment.
