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, proposed capital investment projects, and authorized returns on equity, 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, prudency determinations for wildfire-related costs, the availability and sufficiency of the Wildfire Fund and related cost recovery mechanisms, 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, restrictions on the issuance of dividends 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, including downgrades that may be made if the California legislature does not timely adopt legislation that effectively mitigates the significant wildfire-related risk faced by California investor-owned utilities; ability of Edison International or SCE to borrow funds and access bank and capital markets on reasonable terms; changes in tax laws and regulations, at both the state and federal levels, or changes in the application of those laws, that could affect recorded deferred tax assets and liabilities, effective tax rates and cash flows; changes in rates of inflation (including whether inflation-related adjustments to SCE's authorized revenues allowed by the public utility regulators are commensurate with inflation rates), and changes in interest rates and potential future adjustments to SCE's ROE based on changes in Moody's utility bond rate index; availability and creditworthiness of counterparties and the resulting effects on liquidity in the power and fuel markets and/or the ability of counterparties to pay amounts owed in excess of collateral provided in support of their obligations; and cost of fuel for generating facilities and related transportation, which could be impacted by, among other things, disruption of natural gas storage facilities, to the extent not recovered, timely or at all, through regulated rate cost escalation provisions or balancing accounts.

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.
