EX-99.1 EDISON INTERNATIONAL PRESS RELEASE DATED FEBRUARY 27, 2025 Document Exhibit 99.1 NEWS Investor Relations: Sam Ramraj, (626) 302- 2540 Media Relations : (626) 302- 2255 News@sce.com Edison International Reports Fourth-Quarter and Full-Year 2024 Results • Fourth-quarter 2024 GAAP EPS of $ 0.88; Core EPS of $1.05 • Full-year 2024 GAAP EPS of $3.33; Core EPS of $4.93 • TKM settlement approved, authorizing $1.6 billion of cost recovery for pre-AB 1054 wildfire • Revised 2025 Core EPS guidance of $5.94-$6.34 includes impact of TKM settlement • Continued confidence in delivering 5-7% Core EPS growth from $5.84 (2025) to $6.74-$7.14 (2028) ROSEMEAD, Calif., Feb. 27, 2025 — Edison International (NYSE: EIX) today reported fourth-quarter net income of $340 million, or $ 0.88 per share, compared to net income of $378 million, or $0.99 per share, in the fourth quarter of last year. As adjusted, fourth-quarter core earnings were $405 million, or $1.05 per share, compared to core earnings of $490 million, or $1.28 per share, in the fourth quarter of last year. Southern California Edison’s fourth-quarter 2024 core earnings per share (EPS) de creased year over year, primarily due to higher operation and maintenance expense and higher interest expense, partially offset by higher revenue authorized in Track 4 of SCE's 2021 General Rate Case and an increase in the authorized rate of return resulting from the cost of capital adjustment mechanism. Edison International Parent and Other’s fourth-quarter 2024 core loss per share in creased year over year, primarily due to higher interest expense and gains on preferred stock repurchases in 2023 . “The catastrophic impact of the recent wildfires underscores the importance of grid resiliency and the actions SCE has taken to harden its system to support the communities it serves. SCE continues to execute its robust, risk-prioritized wildfire mitigation plan. We will continue to invest in SCE’s important work to make its system safer for its customers and communities,” said Pedro J. Pizarro, president and CEO of Edison International. “SCE continues to make progress as it works diligently on reconstruction after the Eaton and Palisades fires.” Pizarro added, “We have been actively engaged in conversations with key stakeholders including other utilities, the Governor’s Office and legislative leaders to find solutions to support the safety of the community, effectively manage customer costs and reinforce confidence in California’s utilities. We believe policymakers will act to make the enhancements needed to strengthen the industry-leading AB 1054 regulatory framework.” Full-Year Earnings For 2024, Edison International reported net income of $1,284 million, or $3.33 per share, compared to $1,197 million, or $3.12 per share, for 2023. As adjusted, Edison International’s core earnings were $1,900 million, or $4.93 per share, compared to $1,825 million, or $4.76 per share, in 2023. SCE’s full-year core EPS was higher, primarily due to higher revenue authorized in Track 4 of SCE's 2021 General Rate Case and an increase in the authorized rate of return resulting from the cost of capital adjustment mechanism, partially offset by higher interest expense. Edison International Parent and Other’s full-year loss per share increased primarily due to higher interest expense . Edison International uses core earnings internally for financial planning and analysis of performance. Core earnings 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.

About Edison International Edison International (NYSE: EIX) is one of the nation’s largest electric utility holding companies, focused on providing clean and reliable energy and energy services through its independent companies. Headquartered in Rosemead, California, Edison International is the parent company of Southern California Edison Company, a utility delivering electricity to 15 million people across Southern, Central and Coastal California. Edison International is also the parent company of Trio (formerly Edison Energy), a portfolio of nonregulated competitive businesses providing integrated sustainability and energy advisory services to large commercial, industrial and institutional organizations in North America and Europe. Appendix Use of Non-GAAP Financial Measures Edison International’s earnings are prepared in accordance with generally accepted accounting principles used in the United States and represent the company’s earnings as reported to the Securities and Exchange Commission. Our management uses core earnings and core earnings per share (EPS) internally for financial planning and for analysis of performance of Edison International and Southern California Edison. We also use core earnings and core EPS when communicating with analysts and investors regarding our earnings results to facilitate comparisons of the Company’s performance from period to period. Financial measures referred to as net income, basic EPS, core earnings, or core EPS also apply to the description of earnings or earnings per share. 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 excluding income or loss from discontinued operations and income or loss from significant discrete items that management does not consider representative of ongoing earnings. Basic earnings and losses refer to net income or losses attributable to Edison International shareholders. Core earnings are reconciled to basic earnings in the attached tables. The impact of participating securities (vested awards that earn dividend equivalents that may participate in undistributed earnings with common stock) for the principal operating subsidiary is not material to the principal operating subsidiary’s EPS and is therefore reflected in the results of the Edison International holding company, which is included in Edison International Parent and Other. Safe Harbor Statement Statements contained in this release 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 release, 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), and costs incurred 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 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 affordability on SCE’s ability to obtain regulatory approval of, or cost recovery for, operations and maintenance expenses, proposed capital investment projects, and increased costs due to supply chain constraints, tariffs, inflation and rising interest rates; • 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 and 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 (“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 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; • 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, 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, 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 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: www.edisoninvestor.com .
