1Edison International | April 2026 Business Update 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 costs (including amounts paid for self-insured retention and co-insurance, and amounts not recoverable from the Wildfire Fund), and costs incurred for wildfire restoration efforts and to mitigate the risk of utility equipment causing future wildfires; • the cybersecurity of Edison International's and SCE's critical information technology systems for grid control and business, employee and customer data, and the physical security of Edison International's and SCE's critical assets and personnel; • risks associated with the construction, operation, and maintenance of electrical facilities, including worker, contractor, 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; • impact of affordability of customer rates on SCE's ability to execute its strategy, including the impact of lower-than-expected load growth and higher operating and capital costs (due to factors such as supply chain constraints, tariffs, inflation, and rising interest rates), which could affect SCE’s ability to obtain regulatory approval of, or cost recovery for, operations and maintenance expenses and proposed capital investment projects, as well as influence legislative actions; • ability of SCE to update its grid infrastructure to maintain system integrity and reliability, and meet electrification needs; • ability of SCE to implement its operational and strategic plans, including its Wildfire Mitigation Plan, its target energization times and capital investment program, including challenges related to project site identification, public opposition, environmental mitigation, construction, permitting, contractor performance, changes in the California Independent System Operator's (“CAISO”) transmission plans, and governmental approvals; • 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 the California Wildfire Legislation or anticipated new California legislation 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 or contributing cause, including the longevity of the Wildfire Fund and the California Public Utilities Commission (“CPUC”) interpretation of and actions under the California Wildfire Legislation, including its interpretation of the clarified prudency standard; • 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, the California legislature and other governmental authorities, including decisions and actions related to nationwide or statewide crisis, approval of regulatory proceeding settlements, 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, reforming wildfire-related liability protections available to California investor-owned utilities, wildfire mitigation efforts, approval and implementation of electrification programs, and delays in executive, regulatory and legislative actions; • governmental, statutory, regulatory, or administrative changes or initiatives affecting the electricity industry, including the market structure rules applicable to each market adopted by the North American Electric Reliability Corporation, CAISO, Western Electricity Coordinating Council, and similar regulatory bodies in adjoining regions, and changes in the United States' and California's environmental priorities that lessen the importance placed on greenhouse gas reduction and other climate related priorities; • potential for penalties or disallowances for non-compliance with applicable laws and regulations, including fines, penalties and disallowances related to customer notifications and 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, worker and public safety issues, property damage, outages and other operational issues (such as issues due to damaged infrastructure), PSPS activations and unanticipated costs; • 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); • 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: edisoninvestor.com.

10Edison International | April 2026 Business Update Financial Information AppendixIntroduction Wildfire Mitigation Electrifying the Future: Customers and Clean Energy SB 254 is a key action that demonstrates support for IOU financial stability and its importance for customer affordability… 1. References to “Wildfire Fund” refer to the fund established under AB 1054 in 2019; “New fund” refers to the Continuation Account established under SB 254. Funding of the Continuation Account is dependent upon a determination by the fund administrator and CPUC authorization of extending customer charges 2. If the administrator winds up and terminates the account before the final installment payment is paid, IOUs shall provide one-half of the remaining unpaid installment payments as rate credits to its ratepayers 3. Any remaining value in the Wildfire Fund rolls over to the new fund after satisfying covered wildfires 4. Subject to CPUC approval; SB 254 was signed by the governor on September 19, 2025, which is the effective date of the bill 5. Based on the assumption that SCE’s share will be determined according to its allocation of the IOU contributions to the Continuation Account    Excludes $6Bn in wildfire capex from rate base Creates $18Bn fund with no upfront contribution1 Funded 50/50 by customers and IOUs – IOUs: $300MM/year for 2029–2045 – plus $3.9Bn over 5 years if need determined by administrator2 – Customers: $900MM/year for 2036–2045 SCE share: 47.85% (~$145MM/year starting 2029) New fund available only for wildfires ignited after Sept. 19, 2025 (SB 254’s effective date); initial fund available only for wildfires ignited before effective date1,3 Enhances framework for liability cap, claims, and financing Liability cap now based on year of ignition—improving certainty of amount—rather than year of disallowance If Wildfire Fund1 exhausted, IOU may issue securitized bonds to fund claims payments for covered wildfires ignited between Jan. 1, 2025, and Sept. 19, 20254 If required to reimburse new fund, IOU may reduce reimbursement by amount of contributions paid Gives IOUs right of first refusal for subrogation claim sales for wildfires ignited after SB 254’s effective date IOUs to securitize $6Bn of wildfire mitigation capital spending (SCE share: ~$2.9Bn)5 Constructive for potential Eaton Fire losses

13Edison International | April 2026 Business Update Financial Information AppendixIntroduction Wildfire Mitigation Electrifying the Future: Customers and Clean Energy Wildfire Fund provides liquidity for claims payments and ceiling on liability to reimburse fund AB 1054 Wildfire Fund (Initial Account) Mechanics1 1. This summary is based on Edison International’s interpretation of Assembly Bill 1054 (2019) and clarifications made in Senate Bill 599 (2022) and Senate Bill 254 (2025) 2. “Eligible claims”: claims for third-party damages from covered wildfires less annual utility retention (larger of $1.0 billion or required insurance layer per fund administrator) 3. Excluding general plant and intangibles • Pay out claims to claimants subject to fund administrator approval • Subrogation claims settled at ≤40% approved unless exceptional facts and circumstances; higher amounts may be approved by fund administrator Fund payment of “eligible claims”2 CPUC prudency determination (serious doubt standard if utility holds safety cert.) • Covers claims payments resulting from wildfires ignited on or after July 12, 2019, either (a) caused by PG&E, SCE, or SDG&E, as determined by the governmental agency responsible for determining causation, or (b) asserted to have been caused by PG&E, SCE, or SDG&E, and results in a court-approved dismissal resulting from settlement of third-party damage claims, in excess of annual utility insurance ($1 billion)2 • Claim-paying capacity of $21+ billion. Fund can securitize future contributions if necessary to capitalize the fund • Fund reimbursed if imprudent (see below right), but does not have a separate replenishment mechanism Wildfire Insurance Fund • Liability cap of 20% of T&D Equity Rate Base (~$4.3Bn for SCE for 2025)3 unless found to have acted with conscious or willful disregard of the rights and safety of others • Liability cap lapses when fund exhausted; prudency standard remains If found imprudent, IOU reimburses Wildfire Fund up to 3-year rolling cap If found prudent, IOU does not reimburse Wildfire Fund PG&E: $4.8Bn initial + $193MM annually through 2028 SCE: $2.4Bn initial + $95MM annually through 2028 SDG&E: $0.3Bn initial + $13MM annually through 2028 IOUs contribute $10.5 billion Customers contribute $0.9Bn annually through 2035.

For further details, see "Management Overview—Southern California Wildfires and Mudslides” in the 2025 10-K 3. As of April 27, 2026 4. Refers to funding sources prior to a CPUC determination of prudency. For further details, see "Management Overview—Southern California Wildfires and Mudslides” in the 2025 10-K 5. Customer-funded self-insurance includes a $12.5 million shareholder contribution 6. Subject to CPUC approval. If the CPUC determines that the costs were not prudently incurred, SCE will be required to return any amounts recovered back to customers over a period that matches the remaining duration of the financing instrument through credits to customer rates Clear funding sources mitigate balance sheet exposure from claims resolution4While SCE has not conclusively determined causation, SCE is not aware of evidence pointing to another possible source of ignition. Absent additional evidence, SCE believes that it is likely that its equipment could have been associated with the ignition of the Eaton Fire. Based on the information it has reviewed, SCE believes that it will be able to make a good faith showing that its conduct with respect to its transmission facilities in the preliminary area of origin was consistent with the actions of a reasonable utility.

Management uses core earnings and core EPS internally for financial planning and for analysis of performance. Core earnings and core EPS 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 and core EPS are non-GAAP financial measures and may not be comparable to those of other companies. Core earnings and core EPS are defined as basic earnings and basic EPS 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. The Company is unable to provide a reconciliation of forward-looking core EPS guidance for 2027, 2028, and 2030 to the most directly comparable GAAP measure because certain items affecting GAAP EPS, including but not limited to wildfire-related costs, regulatory outcomes, and other non-core items, are inherently unpredictable and cannot be estimated without unreasonable effort. The probable significance of these items is such that they could have a material impact on GAAP results in future periods.
