California's regulatory mechanisms provide revenue certainty

Revenue Decoupling

Long-standing regulatory mechanism that breaks the link between retail

means earnings aren't

electricity sales and revenue; promotes energy efficiency, helps stabilize customer

affected by changes in

bills, and supports environmental goals

electricity sales

Changes in sales only affect timing of cash collection

Balancing Accounts

SCE has several balancing accounts, including for variances in sales volume, such

allow SCE to collect and

as those related to weather

refund differences to

Balancing account established for incremental residential uncollectibles

authorized revenue

Forecast Ratemaking

reduces regulatory lag

Four-year GRC cycle with forward-looking test year and attrition year increases

CPUC has historically authorized mechanism that gives SCE opportunity to offset some inflationary price increases based on utility-specific indices

Cost of capital proceedings on three-year cycle separate from GRC with mechanism to reasonably adjust cost of capital if market conditions change significantly during cycles

EIX is directly contributing to California's clean energy transition by taking steps to reach net zero

Our Net-Zero Action Plan

Reducing Scope 1, 2, and 3 Emissions

Deliver Carbon-Free Power to

1 SCE's Customers: Increase clean power procurement and decrease natural gas generation use, in line with commitment to deliver 100% carbon-freepower by 2045

Reduce Operational Emissions:

2 Engaging vendors to reduce supply chain emissions, phasing out older technology, and continuing to electrify vehicle fleet

Neutralize remaining emissions:

3 Mostly from natural gas generation supporting reliability and affordability
