Edison International (EIX) Stock Analysis

Edison International’s primary competitive advantage is its regulated monopoly position through Southern California Edison (SCE), which supplies electricity to over 15 million people in a 50,000-square-mile territory—second only to PG&E in California. This geographic exclusivity ensures stable, recession-resistant cash flows and high barriers to entry; rivals such as Sempra Energy’s San Diego Gas & Electric serve far smaller markets.

Regulatory alignment is another key strength. SCE operates under a constructive California regulatory regime that allows for cost recovery and authorized returns on capital investments. The 2025 General Rate Case approved 91% of SCE’s proposed capital plan, supporting a $28–29 billion grid investment through 2028 and underpinning projected 5–7% annual core EPS growth. Decoupling mechanisms further insulate revenue from fluctuations in electricity demand.

EIX’s scale and early adoption of grid modernization and clean energy integration also differentiate it. SCE delivered 52% carbon-free power in 2023, outpacing national averages, and manages one of the largest energy storage portfolios in the U.S. This positions EIX to benefit from California’s aggressive electrification and renewable mandates, while competitors like PG&E and Sempra face similar mandates but with less grid modernization progress.

Risks remain—especially wildfire liability—but EIX’s regulatory, operational, and infrastructure advantages provide a durable edge in a capital-intensive, policy-driven industry.
