Edison International

Edison International is the parent holding company of Southern California Edison Company (SCE), one of the largest investor-owned electric utilities in the United States, supplying electricity to approximately 5.4 million customer accounts across a 50,000-square-mile service territory in central, coastal, and southern California. Through SCE, Edison International functions as a regulated wires-and-infrastructure business whose earnings derive from the authorized return on a growing rate base — not from the volume of electricity sold — making it, in economic substance, a long-duration infrastructure compounder operating inside a regulatory compact.

This is a story about an essential monopoly earning regulated returns on a ~$48 billion rate base, with a 5–7% core EPS growth algorithm, a 4.5% dividend yield, and a 22-year streak of annual dividend increases — trading at approximately 8 times trailing GAAP earnings. The discount exists because California's wildfire liability regime, the state's inverse condemnation doctrine, and the uncertain fate of legislative reform represent a genuine and non-diversifiable risk to the equity. The central question is whether California's political system will deliver a durable framework that preserves the utility's access to affordable capital before credit-rating downgrades and rising financing costs impair the compounding engine. The file turns on a judgment about that probability.
