February 23, 2023 Fourth Quarter and Full-Year 2022 Financial Results

1 Statements contained in this presentation about future performance, including, without limitation, operating results, capital expenditures, rate base growth, dividend policy, financial outlook, and other statements that are not purely historical, are forward-looking statements. These forward-looking statements reflect our current expectations; however, such statements involve risks and uncertainties. Actual results could differ materially from current expectations. These forward-looking statements represent our expectations only as of the date of this presentation, and Edison International assumes no duty to update them to reflect new information, events or circumstances. Important factors that could cause different results include, but are not limited to the: • ability of SCE to recover its costs through regulated rates, including uninsured wildfire-related and debris flow-related costs, costs incurred to mitigate the risk of utility equipment causing future wildfires, costs incurred as a result of the COVID-19 pandemic, and increased costs due to supply chain constraints, inflation, and rising interest rates; • ability of SCE to implement its Wildfire Mitigation Plan and capital program; • risks of regulatory or legislative restrictions that would limit SCE's ability to implement operational measures to mitigate wildfire risk, including Public Safety Power Shutoff (“PSPS”) and fast curve settings, when conditions warrant or would otherwise limit SCE's operational practices relative to wildfire risk mitigation; • risks associated with SCE implementing PSPS, including regulatory fines and penalties, claims for damages and reputational harm; • ability of SCE to maintain a valid safety certification; • ability of Edison International and SCE to obtain sufficient insurance at a reasonable cost, including insurance relating to wildfire-related claims, and to recover the costs of such insurance or, in the event liabilities exceed insured amounts, the ability to recover uninsured losses (including amounts paid for self-insured retention and co-insurance) from customers or other parties; • extreme weather-related incidents (including events caused, or exacerbated, by climate change, such as wildfires, debris flows, flooding, droughts, high wind events and extreme heat events) and other natural disasters (such as earthquakes), which could cause, among other things, public safety issues, property damage, rotating outages and other operational issues (such as issues due to damaged infrastructure), PSPS activations and unanticipated costs; • risk that California Assembly Bill 1054 (“AB 1054”) does not effectively mitigate the significant exposure faced by California investor-owned utilities related to liability for damages arising from catastrophic wildfires where utility facilities are alleged to be a substantial cause, including the longevity of the Wildfire Insurance Fund and the CPUC's interpretation of and actions under AB 1054, including its interpretation of the prudency standard clarified by AB 1054; • ability of Edison International and SCE to effectively attract, manage, develop and retain a skilled workforce, including its contract workers; • decisions and other actions by the California Public Utilities Commission, the Federal Energy Regulatory Commission, the Nuclear Regulatory Commission and other governmental authorities, including decisions and actions related to nationwide or statewide crisis, determinations of authorized rates of return or return on equity, the recoverability of wildfire-related and debris flow-related costs, issuance of SCE's wildfire safety certification, wildfire mitigation efforts, approval and implementation of electrification programs, and delays in executive, regulatory and legislative actions; • cost and availability of labor, equipment and materials, including as a result of supply chain constraints and inflation; • ability of Edison International or SCE to borrow funds and access bank and capital markets on reasonable terms; • risks associated with the decommissioning of San Onofre, including those related to worker and public safety, public opposition, permitting, governmental approvals, on-site storage of spent nuclear fuel and other radioactive material, delays, contractual disputes, and cost overruns; • pandemics, such as COVID-19, and other events that cause regional, statewide, national or global disruption, which could impact, among other things, Edison International's and SCE's business, operations, cash flows, liquidity and/or financial results and cause Edison International and SCE to incur unanticipated costs; • physical security of Edison International's and SCE's critical assets and personnel and the cybersecurity of Edison International's and SCE's critical information technology systems for grid control, and business, employee and customer data; • risks associated with cost allocation resulting in higher rates for utility bundled service customers because of possible customer bypass or departure for other electricity providers such as Community Choice Aggregators (“CCA,” which are cities, counties, and certain other public agencies with the authority to generate and/or purchase electricity for their local residents and businesses) and Electric Service Providers (entities that offer electric power and ancillary services to retail customers, other than electrical corporations (like SCE) and CCAs); • risks inherent in SCE’s capital investment program, including those related to project site identification, public opposition, environmental mitigation, construction, permitting, contractor performance, changes in the California Independent System Operator’s transmission plans, and governmental approvals; and • risks associated with the operation of electrical facilities, including worker and public safety issues, the risk of utility assets causing or contributing to wildfires, failure, availability, efficiency, and output of equipment and facilities, and availability and cost of spare parts. Other important factors are discussed under the headings “Forward-Looking Statements”, “Risk Factors” and “Management’s Discussion and Analysis” in Edison International’s Form 10-K and other reports filed with the Securities and Exchange Commission, which are available on our website: www.edisoninvestor.com. These filings also provide additional information on historical and other factual data contained in this presentation. Forward-Looking Statements February 23, 2023

5 SCE estimates its wildfire mitigation and PSPS have reduced probability of losses from catastrophic wildfires by ~75–80%1,2 February 23, 2023 1. Baseline risk estimated by RMS using its wildfire model, the location of SCE’s assets, and SCE reported ignitions from 2014-2020. Risk reduction calculated by applying SCE-provided mitigation effectiveness and locations of covered conductor, tree removals, inspections, line clearing, and PSPS. Range may vary for other loss thresholds 2. Includes 50,000 year-long simulations using 20 years of weather and fire modeling weighted for the last 5 years to reflect recent experience and climate-change impacts 3. Annual losses represent potential claims resulting from wildfire. Total potential insured losses, such as damages to assets of homeowners and businesses, estimated by RMS, and uninsured losses, such as personal injury, fire suppression, and damage to publicly-owned assets estimated by SCE based on management experience and judgment 4. Fund refers to AB 1054 Wildfire Insurance Fund. SCE used the one-year RMS loss estimates with its estimates for the size of uninsured losses to quantify the reduction in probability of experiencing $3.5 billion in losses over a three-year period, excess of $1 billion aggregate each year, after which the AB 1054 liability cap would apply SCE expects to further reduce risk and decrease the need for PSPS with continued grid hardening investments Pre-20184 Year-End 2022 Estimated Risk Reduction PSPS Contribution Annual Risk of ≥$1.0 billion loss3 ~5.2% ~1.2% ~75% reduction in estimated probability of accessing the Wildfire Fund Risk of ≥$3.5 billion drawn from Fund over 3 years3 ~2.9% ~0.6% ~80% reduction in estimated probability of exceeding AB 1054 liability cap 1. Baseline risk estimated by Risk Management Solutions, Inc. (Moody’s RMS) using its wildfire model, relying on the following data provided by SCE: the location of SCE’s assets, reported ignitions from 2014–2020, mitigation effectiveness and locations of installed covered conductor, tree removals, inspections, line clearing, and PSPS de-energization criteria 2. There are risks inherent in the simulation analysis, models and predictions of SCE and Moody’s RMS relating to the likelihood of and damage due to wildfires and climate change. As with any simulation analysis or model related to physical systems, particularly those with lower frequencies of occurrence and potentially high severity outcomes, the actual losses from catastrophic wildfire events may differ from the results of the simulation analysis and models of Moody’s RMS and SCE. Range may vary for other loss thresholds 3. Includes (i) total potential insured losses estimated by Moody’s RMS, and (ii) total potential uninsured losses estimated by SCE based on management experience and consultation with insurance industry experts. “Fund” refers to CA AB 1054 Wildfire Insurance Fund. SCE used Moody’s RMS loss estimates along with its estimates of uninsured losses to quantify the reductions in estimated probability 4. Moody’s RMS’s prior method of analysis regarding wildfire risk on the wildfire models was updated at SCE’s request in Q2 2022 to incorporate Moody’s RMS’s newly available climate change models, leading to adjustments to pre-2018 probabilities and in quantifying the current year-end 2022 probabilities Decreasing dependency on PSPS vs. ~30% as of Q4 20214 ~15% of total risk reduction

6 Covered conductor deployment has reduced SCE’s dependency on PSPS for reducing wildfire risk February 23, 2023 1. Baseline risk estimated by Risk Management Solutions, Inc. (Moody’s RMS) using its wildfire model, relying on the following data provided by SCE: the location of SCE’s assets, reported ignitions from 2014–2020, mitigation effectiveness and locations of installed covered conductor, tree removals, inspections, line clearing, and PSPS de-energization criteria. 2. There are risks inherent in the simulation analysis, models and predictions of SCE and Moody’s RMS relating to the likelihood of and damage due to wildfires and climate change. As with any simulation analysis or model related to physical systems, particularly those with lower frequencies of occurrence and potentially high severity outcomes, the actual losses from catastrophic wildfire events may differ from the results of the simulation analysis and models of Moody’s RMS and SCE. Range may vary for other loss thresholds 3. PSPS and System Hardening Values are estimated by SCE based on operational experience in 2018–2020 compared to the subsequent modeled years SCE’s approach to reducing wildfire risk is differentiated by its focus on expeditiously hardening its infrastructure Estimated reduction in probability of losses from catastrophic wildfires compared to pre-2018 levels1,2,3 20% 55–60% 55–60% 65–70% 75–80% 2018 2019 2020 2021 2022 Public Safety Power Shutoffs (PSPS) Physical Mitigation (Grid hardening, inspections, vegetation management) ~125 ~495 ~1,480 ~2,980 ~4,400 Cumulative miles of covered conductor installed: Current

26 Edison International's earnings are prepared in accordance with generally accepted accounting principles used in the United States. Management uses core earnings (losses) internally for financial planning and for analysis of performance. Core earnings (losses) are also used when communicating with investors and analysts regarding Edison International's earnings results to facilitate comparisons of the company's performance from period to period. Core earnings (losses) are a non-GAAP financial measure and may not be comparable to those of other companies. Core earnings (losses) are defined as earnings attributable to Edison International shareholders less non-core items. Non-core items include income or loss from discontinued operations and income or loss from significant discrete items that management does not consider representative of ongoing earnings, such as write downs, asset impairments and other income and expense related to changes in law, outcomes in tax, regulatory or legal proceedings, and exit activities, including sale of certain assets and other activities that are no longer continuing.
