FEBRUARY 22, 2024 FOURTH-QUARTER AND FULL-YEAR 2023 FINANCIAL RESULTS

Edison International | Fourth-Quarter 2023 Earnings Call 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, timely or at all, including uninsured wildfire-related and debris flow-related costs (including amounts paid for self-insured retention and co-insurance), 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; • impact of affordability of customer rates on SCE's ability to execute its strategy, including the impact of affordability on the approval of operations and maintenance expenses, and proposed capital investment projects; • ability of SCE to implement its operational and strategic plans, including 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; • ability of SCE to obtain safety certifications from the Office of Energy Infrastructure Safety of the California Natural Resources Agency (“OEIS“) • 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 California Public Utilities Commission (“CPUC”) interpretation of and actions under AB 1054, including its interpretation of the prudency standard clarified by AB 1054; • 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; • 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; • 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 CPUC, the Federal Energy Regulatory Commission, and the United States 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; • potential for penalties or disallowances for non-compliance with applicable laws and regulations, including fines, penalties and disallowances related to wildfires where SCE's equipment is alleged to be associated with ignition; • 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; • 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; • 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 • actions by credit rating agencies to downgrade Edison International or SCE’s credit ratings or to place those ratings on negative watch or negative outlook. 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

Edison International | Fourth-Quarter 2023 Earnings Call 5 SCE has reduced use of PSPS for lowering wildfire risk through use of covered conductor and other physical mitigation 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–Q3 2023, mitigation effectiveness and locations of installed covered conductor, tree removals, inspections, line clearing, fast curve settings, 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 wildfire risk mitigation is differentiated by its speed of hardening its infrastructure Estimated reduction in probability of catastrophic losses using the independent Moody’s RMS wildfire risk model compared to pre-2018 levels 1,2,3 20% 55–60% 55–60% 65–70% 75–80% 85–88% 2018 2019 2020 2021 2022 2023 Public Safety Power Shutoffs (PSPS) (Contribution has declined from 100% to ~10%) Physical Mitigation (Grid hardening (e.g., covered conductor), inspections, vegetation management) ~125 ~495 ~1,480 ~2,980 ~4,400 Cumulative miles of covered conductor installed: Current 5,580+

Edison International | Fourth-Quarter 2023 Earnings Call 33 Use of Non-GAAP Financial Measures 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, wildfire-related claims, 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. A reconciliation of Non-GAAP information to GAAP information is included either on the slide where the information appears or on another slide referenced in this presentation.
