Company Description
Edison International (NYSE: EIX) is an electric utility holding company in the utilities sector. According to company disclosures, Edison International is focused on providing clean and reliable energy and energy services through its independent companies. It is headquartered in Rosemead, California and is described in multiple filings and press releases as one of the nation’s largest electric utility holding companies.
The company’s primary utility subsidiary is Southern California Edison Company (SCE). Edison International states that SCE delivers electricity to approximately 15 million people across Southern, Central and Coastal California. SCE serves this population via about 5 million customer accounts in a service area of roughly 50,000 square miles, as noted in recent press releases about SCE and its trust preference securities. This regulated utility business is a core component of Edison International’s overall operations.
In addition to its regulated utility, Edison International is also the parent of Trio (formerly Edison Energy). The company describes Trio as a portfolio of nonregulated competitive businesses that provide integrated sustainability and energy advisory services to large commercial, industrial and institutional organizations in North America and Europe. These activities are separate from the regulated utility and reflect Edison International’s participation in competitive energy-related services and sustainability advisory work.
Business structure and focus
Based on the company’s own descriptions, Edison International’s business is organized around two main areas:
- Regulated electric utility operations through Southern California Edison, which delivers electricity to residential, commercial and other customers in its California service territory.
- Nonregulated energy and sustainability advisory services through Trio, serving large organizations in North America and Europe.
Edison International characterizes its overall focus as providing clean and reliable energy and energy services. Within its utility operations, recent company communications reference grid investments, wildfire mitigation, and regulatory proceedings with the California Public Utilities Commission (CPUC), indicating that regulatory decisions and cost recovery mechanisms are important to its business environment. For example, an 8-K filing describes CPUC decisions on SCE’s cost of capital and general rate case, which affect the authorized rate of return and capital structure for the utility.
Regulatory and financial context
Edison International and Southern California Edison are regulated by agencies including the CPUC and the Federal Energy Regulatory Commission, as reflected in the company’s filings. The company uses both GAAP earnings and non-GAAP measures such as core earnings and core earnings per share (core EPS) for internal planning and external communications. In its earnings-related 8-Ks, Edison International explains that core EPS excludes certain significant discrete items that management does not consider representative of ongoing earnings.
The company’s filings and press releases also discuss topics such as wildfire-related cost recovery, securitization of certain costs, and the use of the California Wildfire Insurance Fund. These disclosures emphasize the importance of regulatory outcomes, cost recovery proceedings, and legislative developments (such as California Senate Bill 254 and Assembly Bill 1054) to Edison International’s financial profile and risk management, particularly in relation to wildfire exposure.
Capital structure and financing activities
Edison International’s recent SEC filings describe various financing and capital structure actions. For example, an 8-K dated December 23, 2025 reports that Edison International entered into a Term Loan Credit Agreement providing for a term loan that may be used for general corporate and working capital purposes, including potential repayment of debt. Other filings and press releases discuss tender offers for preferred stock and trust preference securities, as well as redemptions of certain securities at Southern California Edison-related trusts.
These activities illustrate how Edison International manages its capital structure through a combination of debt facilities, preferred securities, and regulatory capital frameworks. A CPUC decision summarized in an 8-K sets out authorized capital structure components (long-term debt, preferred equity, and common equity) and associated costs of capital for SCE, which together determine the utility’s authorized rate of return.
Risk factors and operating environment
In its earnings press release and related materials, Edison International highlights a range of risks associated with its operations. These include the ability of Southern California Edison to recover costs through regulated rates, wildfire-related and debris flow-related costs, cybersecurity and physical security risks, and operational risks associated with electrical facilities. The company also references the impact of customer rate affordability, supply chain constraints, inflation, and interest rates on its operations and regulatory approvals.
Additional risks described by the company include extreme weather events and other natural disasters, wildfire mitigation and safety certification processes, and the decommissioning of the San Onofre nuclear generating station. The company also notes potential impacts from customer migration to other electricity providers such as Community Choice Aggregators and Electric Service Providers, which can affect cost allocation and rates for remaining bundled service customers.
Corporate history elements
Background information from earlier descriptions notes that Edison International has acted as the parent company of Southern California Edison and has previously owned other energy-related businesses. The company’s historical activities have included ownership of nonutility energy businesses. A prior description notes that Edison Mission Energy, a wholesale power generation subsidiary, was sold out of bankruptcy to another energy company in 2014. This reflects Edison International’s evolution over time and its current focus on regulated utility operations and nonregulated advisory businesses.
Community and educational initiatives
Edison International also engages in philanthropic and community-focused programs. A recent press release describes the Edison Scholars program, a scholarship initiative funded by the Edison International Foundation. The program awards scholarships to high school seniors in Southern California Edison’s service area who plan to pursue degrees in science, technology, engineering or math (STEM). The company notes that scholarship recipients may also apply for paid internships with Southern California Edison and that the program has provided significant scholarship funding to hundreds of students over many years.

The company emphasizes clean and reliable energy, operates under extensive regulatory oversight, and discloses detailed information about its earnings measures, wildfire-related exposures, and capital structure in SEC filings and press releases.
