July 28, 2022 Second Quarter 2022 Financial Results

1 Statements contained in this presentation about future performance, including, without limitation, operating results, capital ex penditures, rate base growth, dividend policy, financial outlook, and other statements that are not purely historical, are forward - looking statements. These forward - looking statements r eflect our current expectations; however, such statements involve risks and uncertainties. Actual results could differ materially from current expectations. These forward - looking stateme nts 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. Im por tant 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 labor and materials costs due to su pply chain constraints and inflation; • 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 Public Safety Power Shutoff (“PSP S”) when conditions warrant or would otherwise limit SCE’s operational PSPS practices; • risks associated with implementing PSPS, including regulatory fines and penalties, claims for damages and reputational harm; • ability of SCE to maintain a valid safety certification; • ability to obtain sufficient insurance at a reasonable cost, including insurance relating to wildfire - related claims, and to rec over the costs of such insurance or, in the event liabilities exceed insured amounts, the ability to recover uninsured losses from customers or other parties; • extreme weather - related incidents (including events caused, or exacerbated, by climate change, such as wildfires, debris flows, 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, ope rational issues (such as rotating outages and 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 Californi a i nvestor - owned utilities related to liability for damages arising from catastrophic wildfires where utility facilities are alleged to be a substantial cause, including the longevity o f t he Wildfire Insurance Fund and the CPUC's interpretation of and actions under AB 1054, including its interpretation of the prudency standard established under AB 1054; • ability of Edison International and SCE to effectively attract, manage, develop and retain a skilled workforce, including its co ntract workers; • decisions and other actions by the California Public Utilities Commission, the Federal Energy Regulatory Commission, the Nucl ear Regulatory Commission and other governmental authorities, including decisions and actions related to nationwide or statewide crisis, determinations of authorized rates of re turn 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 an d 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; • 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 oppositi on, 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 unantici pat ed costs; • physical security of Edison International's and SCE's critical assets and personnel and the cybersecurity of Edison Internati ona l'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 cus tom er 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 g ene rate 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 , o ther than electrical corporations (like SCE) and CCAs); • risks inherent in SCE’s capital investment program, including those related to project site identification, public opposition , e nvironmental mitigation, construction, permitting, 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 ass ets 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 Discussi on 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.c om. These filings also provide additional information on historical and other factual data contained in this presentation. Forward - Looking Statements July 28, 2022

22 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. 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.
