EIX · Edison International

Edison International furnished a business update presentation (Exhibit 99.1) for use in meetings with institutional investors and analysts. The presentation outlines a significant capital investment opportunity of $38-41 billion from 2026 through 2030, primarily at its subsidiary Southern California Edison (SCE), focused on strengthening and modernizing the grid and supporting California's aggressive climate goals. Key wildfire mitigation strategies include installing 100% covered conductor on all distribution lines by 2030, expanding weather monitoring networks, and deploying AI-based risk modeling. The company highlights legislative support through California's SB 254 (passed September 2025) and AB 1054 (July 2019), which established a $21+ billion initial wildfire fund and a continuation account, along with a codified prudent manager standard for cost recovery. SCE's wires-focused rate base and limited power generation ownership are noted as structural advantages. The presentation also emphasizes SCE's role as one of the nation's largest electric-only utilities, serving over 5 million customer accounts. No specific financial results or guidance were provided in the filing.
