Note 1. Summary of Significant Accounting Policies

Organization and Basis of Presentation

Edison International is the ultimate parent holding company of SCE and Edison Energy, LLC, doing business as Trio. SCE is an investor-owned public utility primarily engaged in the business of supplying and delivering electricity to an approximately 50,000 square mile area across Southern, Central, and Coastal California. Trio is a global energy advisory firm providing integrated sustainability and energy solutions to commercial, industrial, and institutional customers. Trio's business activities are currently not material to report as a separate business segment, and SCE is the single reportable segment. See "Segment Information" below for further discussion.

These combined notes to the condensed consolidated financial statements apply to both Edison International and SCE unless otherwise described. Edison International's condensed consolidated financial statements include the accounts of Edison International, SCE, and other controlled subsidiaries. References to Edison International refer to the consolidated group of Edison International and its subsidiaries. References to "Edison International Parent and Other" refer to Edison International Parent and its competitive subsidiaries and "Edison International Parent" refer to Edison International on a stand-alone basis, not consolidated with its subsidiaries. SCE's condensed consolidated financial statements include the accounts of SCE, its controlled subsidiaries and a variable interest entity, SCE Recovery Funding LLC, of which SCE is the primary beneficiary. All intercompany transactions have been eliminated from the condensed consolidated financial statements.

Edison International's and SCE's significant accounting policies were described in the "Notes to Consolidated Financial Statements" included in the 2025 Form 10-K. This quarterly report should be read in conjunction with the financial statements and notes included in the 2025 Form 10-K.

In the opinion of management, all adjustments, consisting only of adjustments of a normal recurring nature, have been made that are necessary to fairly state the condensed consolidated financial position, results of operations, and cash flows in accordance with accounting principles generally accepted in the United States ("GAAP") for the periods covered by this quarterly report on Form 10-Q. The results of operations for the interim periods presented are not necessarily indicative of the operating results for the full year.

The December 31, 2025 financial statement data was derived from the audited financial statements, but does not include all disclosures required by GAAP for complete annual financial statements.

Segment Information

For information on Edison International's and SCE's segment information, see Note 1 in the 2025 Form 10-K. In addition, for the three months ended March 31, 2026 and 2025, Edison International's and SCE's significant segment expenses agree to those disclosed in the condensed consolidated statements of income. As of March 31, 2026 and 2025, the measures of Edison International's and SCE's segment assets are reported on Edison International's and SCE's condensed consolidated balance sheets, respectively, as total assets.

Tableof Contents

Cash and Cash Equivalents and Restricted Cash and Cash Equivalents

The following table sets forth the cash, cash equivalents, restricted cash and restricted cash equivalents included in the condensed consolidated statements of cash flows:

1Cash equivalents consist of investments in money market funds. Generally, the carrying value of cash equivalents equals the fair value, as these investments have original maturities of three months or less.

2Includes SCE Recovery Funding LLC's restricted cash for payments of senior secured recovery bonds and cash collected for customer-funded wildfire self-insurance related to settlements (see Note 12 for further information). Both are reflected in "Other current assets" on Edison International's and SCE's condensed consolidated balance sheets.

3Represents cash collected for customer-funded wildfire self-insurance and is reflected in "Other long-term assets" on Edison International's and SCE's condensed consolidated balance sheets. See Note 12 for further information.

Allowance for Uncollectible Accounts

The allowance for uncollectible accounts is recorded based on SCE's estimate of expected credit losses and adjusted over the life of the receivables as needed. Since the customer base of SCE is concentrated in Southern California which exposes SCE to a homogeneous set of economic conditions, the allowance is measured on a collective basis on the historical amounts written-off, assessment of customer collectibility, and current economic indicators, such as unemployment rates. In estimating expected credit losses, SCE applies a practical expedient under the current expected credit loss model, which assumes that current economic conditions as of the balance sheet date do not change over the remaining life of existing accounts receivable. The decrease in write-offs for the three months ended March 31, 2026, is primarily a result of higher disconnection activities and collections efforts undertaken in 2025, the effects of which flowed through to write-offs recorded in 2026.

The following table sets forth the changes in allowance for uncollectible accounts for SCE:

1This includes $44 million and $66 million of incremental costs, for the three months ended March 31, 2026 and 2025, respectively, which were probable of recovery from customers and recorded as regulatory assets.

2Approximately $39 million and $49 million of allowance for uncollectible accounts are included in "Other long-term assets" on SCE's condensed consolidated balance sheets as of March 31, 2026 and December 31, 2025, respectively.

Wildfire Fund

The Wildfire Fund does not have a defined life and instead will terminate when the fund administrator determines that the fund has been exhausted. SCE estimates the period of coverage of the fund and amortizes contributions made to the Wildfire Fund ratably over the period of coverage similar to prepaid insurance. Estimating the period of coverage of the fund requires significant judgment. Frequency of wildfire events and estimated costs associated with wildfire events caused by participating utilities are among the significant factors used to estimate the fund's period of coverage.

Edison International and SCE reassess the period of coverage of the fund at least annually in the first quarter each year and when new or additional information becomes available. As of the date of filing, after considering the current accrued losses

Tableof Contents

for the Eaton Fire, SCE does not have new or additional information that would enable it to change its prior assessment that the Wildfire Fund would provide coverage for an estimated 20 years from the date SCE committed to participate in the Wildfire Fund. When updating its estimate, SCE includes all its fires for which losses can be reasonably estimated, and relies on publicly disclosed wildfire-related losses related to other participating utilities. As discussed in Note 12, while SCE believes that it will incur material losses in connection with the Eaton Fire, it is currently unable to reasonably estimate a range of losses that may be incurred. The Wildfire Fund amortization period will be evaluated and adjusted prospectively as new or additional information on contributions and wildfire events, including reasonably estimated losses related to the Eaton Fire, becomes available. An impairment will be recorded to the Wildfire Fund contribution asset, if the asset exceeds SCE's ability to benefit from the remaining coverage provided by the Wildfire Fund.

SB 254 expands the Wildfire Fund originally created under AB 1054 by establishing the Continuation Account within the Wildfire Fund. As of March 31, 2026, and as of the date of this filing, the conditions required to trigger investor-owned utility contributions to the Continuation Account have not been met. Accordingly, SCE has not recorded a contribution obligation associated with the Continuation Account on its condensed consolidated balance sheets as of March 31, 2026.

As of March 31, 2026, SCE has recorded a receivable of $295 million from the Wildfire Fund, reflected in "Long-term insurance receivables." Based on the California Wildfire Legislation, a utility that submits claims to the Wildfire Fund for recovery is expected to receive such reimbursements from the Wildfire Fund, and separately file an application with CPUC for review of its costs and expenses. See Note 12 for further information. The outcome of the CPUC's prudency review could result in a refund to the Wildfire Fund. SCE will recognize a payable related to claim reimbursements to the Wildfire Fund if it determines that refund to the Wildfire Fund is probable and estimable. SCE considers whether any party in the CPUC prudency review proceeding would prevail in raising a "serious doubt" as of the reasonableness of SCE's actions, and whether it is probable the CPUC would conclude that SCE does not meet the burden of dispelling that doubt and find SCE's conduct was not prudent. SCE considers factors within and outside SCE's control in its evaluation of whether a refund to the Wildfire Fund is probable and estimable. As of March 31, 2026, SCE determined it is not probable nor estimable that any amounts may be required to be reimbursed to the Wildfire Fund.

Earnings Per Share

Edison International computes earnings per common share ("EPS") using the two-class method, which is an earnings allocation formula that determines EPS for each class of common stock and participating security. Edison International's participating securities are stock-based compensation awards, payable in common shares, which earn dividend equivalents on an equal basis with common shares once the awards are vested.

EPS available to Edison International common shareholders was computed as follows:

In addition to the participating securities discussed above, Edison International also may award stock options, which are payable in common shares and are included in the diluted earnings per share calculation. Stock option awards to purchase 2,241,826 and 8,203,681 shares of common stock for the three months ended March 31, 2026 and 2025, respectively, were

Tableof Contents

outstanding, but were not included in the computation of diluted earnings per share because the effect would have been antidilutive.

Revenue Recognition

Revenue is recognized by Edison International and SCE when a performance obligation to transfer control of the promised goods is satisfied or when services are rendered to customers. This typically occurs when electricity is delivered to customers, which includes amounts for services rendered but unbilled at the end of a reporting period.

Regulatory Proceedings

FERC 2026 Formula Rate Update

In November 2025, SCE filed its 2026 annual transmission revenue requirement update with the FERC, with rates effective January 1, 2026, subject to settlement procedures and refund. SCE requested an increase in SCE's transmission revenue requirement of $1.5 billion, which is $157 million, or 12% higher than amounts included in the 2025 annual rates. The increase is primarily due to 2026 rates reflecting recovery of previous undercollections. Pending resolution of the FERC formula rate proceedings, SCE recognized revenue in the first three months of 2026 based on the FERC 2026 annual updated rates, subject to refund.

New Accounting Guidance

Accounting Guidance Not Yet Adopted

In November 2024, the FASB issued an accounting standards update requiring public entities to provide disaggregated disclosure of income statement expenses. The guidance does not change the expense captions an entity presents on the face of the income statement, rather, it requires disaggregation of certain expense captions into specified categories in disclosures within the footnotes to the financial statements. The guidance is effective for annual disclosure for the year ended December 31, 2027 and subsequent interim periods with early adoption permitted. The guidance is applied prospectively. Edison International and SCE are currently evaluating the impact of the increased disclosures from the new guidance.

In September 2025, the FASB issued an accounting standards update to amend certain aspects of the accounting for and disclosure of internal-use software. Among other things, the guidance removes all references to prescriptive and sequential software development stages and instead requires entities to begin capitalizing software costs when certain criteria are met. The guidance is effective for annual periods after January 1, 2028 and interim reporting periods within those annual reporting periods with early adoption permitted. The guidance can be applied prospectively, retrospectively, or via a modified prospective transition method. Edison International and SCE are currently evaluating the impact of this new guidance.

In December 2025, the FASB issued an accounting standards update to establish guidance on the recognition, measurement, and presentation of government grants received by business entities. The guidance is effective in annual periods beginning after January 1, 2029 and interim periods within those annual reporting periods with early adoption permitted. The guidance can be applied on a modified prospective basis, a modified retrospective basis, or a full retrospective basis. Edison International and SCE are currently evaluating the impact of this new guidance.

The following tables provide Edison International's changes in equity:

Tableof Contents

The following tables provide SCE's changes in equity:

Note 3. Variable Interest Entities

A VIE is defined as a legal entity that meets any of the following conditions: (1) the total equity investment at risk is not sufficient to fund the entity's activities without additional subordinated financial support, (2) the equity holders as a group, lack any of the following characteristics: the power to direct activities that most significantly impact the entity's economic performance, substantive voting rights, the obligation to absorb losses, or the right to receive the expected residual returns of the entity. The primary beneficiary is identified as the variable interest holder that has both the power to direct the activities of the VIE that most significantly impact the entity's economic performance, and the obligation to absorb losses or the right to receive benefits from the entity that could potentially be significant to the VIE. The primary beneficiary is required to consolidate the VIE. Commercial and operating activities are generally the factors that most significantly impact the economic performance of such VIEs.

Variable Interest in VIEs that are Consolidated

SCE Recovery Funding LLC is a bankruptcy remote, wholly owned special purpose subsidiary of SCE, formed for the purpose of issuing securitized bonds. This entity is a VIE because its equity investment is insufficient to support its operations. The most significant activity of SCE Recovery Funding LLC is to service the securitized bonds according to the decisions made by SCE. Therefore, SCE is determined to be the primary beneficiary and consolidates SCE Recovery Funding LLC.

SCE Recovery Funding LLC has issued a total of $3.2 billion of securitized bonds. The proceeds were used to acquire SCE's right, title and interest in and to non-bypassable rates and other charges to be collected from certain existing and future customers in SCE's service area ("Recovery Property"), associated with the AB 1054 Excluded Capital Expenditures and costs approved for recovery under the TKM Settlement Agreement, until the bonds are paid in full, and all financing costs have been recovered. The securitized bonds are secured by the Recovery Property and cash collections from the non-bypassable rates and other charges are the sole source of funds to satisfy the debt obligation. The bondholders have no recourse to SCE.

Tableof Contents

The following table summarizes the impact of SCE Recovery Funding LLC on SCE's and Edison International's condensed consolidated balance sheets.

1The bondholders have no recourse to SCE. The long-term debt balance is net of unamortized debt issuance costs.

Variable Interest in VIEs that are not Consolidated

Power Purchase Agreements

SCE has certain PPAs where the counterparty entities meet one or both of the VIE conditions discussed above and in which SCE has variable interests, including: agreements through which SCE provides natural gas to fuel the plants, fixed price contracts for renewable energy, and resource adequacy agreements that allow purchase of energy at fixed prices upon the seller's election. Since payments for capacity are the primary source of income, the most significant economic activity for these VIEs is typically the operation and maintenance of the power plants, which SCE does not perform. Therefore, SCE has concluded that it is not the primary beneficiary of any of these VIEs because it does not control the commercial and operating activities that most significantly impact the economic performance of these entities.

As of the balance sheet date, the carrying amount of assets and liabilities included in SCE's condensed consolidated balance sheet that relate to involvement with VIEs that are not consolidated, result from amounts due under the PPAs. Under these contracts, SCE recovers the costs incurred through demonstration of compliance with its CPUC-approved long-term power procurement plans. SCE has no residual interest in the entities and has not provided or guaranteed any debt or equity support, liquidity arrangements, performance guarantees, or other commitments associated with these contracts other than the purchase commitments described in Note 12 of the 2025 Form 10-K. As a result, there is no significant potential exposure to loss to SCE from its variable interest in these VIEs. The aggregate contracted capacity dedicated to SCE from these VIE projects was 6,064 MW and 5,300 MW at March 31, 2026 and 2025, respectively. The amounts that SCE paid to these projects were $204 million and $172 million for the three months ended March 31, 2026 and 2025, respectively. These amounts are recoverable in customer rates, subject to a reasonableness review.

Note 4. Fair Value Measurements

Recurring Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (referred to as an "exit price"). Fair value of an asset or liability considers assumptions that market participants would use in pricing the asset or liability, including assumptions about nonperformance risk. As of March 31, 2026 and December 31, 2025, nonperformance risk was not material for Edison International or SCE.

Assets and liabilities are categorized into a three-level fair value hierarchy based on valuation inputs used to determine fair value.

Level 1 – The fair value of Edison International's and SCE's Level 1 assets and liabilities is determined using unadjusted quoted prices in active markets that are available at the measurement date for identical assets and liabilities. This level includes exchange-traded equity securities, U.S. treasury securities, mutual funds, and money market funds.

Level 2 – Edison International's and SCE's Level 2 assets and liabilities include fixed income securities, primarily consisting of U.S. government and agency bonds, municipal bonds and corporate bonds, and over-the-counter commodity derivatives. The fair value of fixed income securities is determined using a market approach by obtaining quoted prices for similar assets and liabilities in active markets and inputs that are observable, either directly or indirectly, for substantially the full term of the instrument.

The fair value of SCE's over-the-counter commodity derivative contracts is determined using an income approach. SCE uses standard pricing models to determine the net present value of estimated future cash flows. Inputs to the pricing models

Tableof Contents

include forward published or posted clearing prices from an exchange (Intercontinental Exchange) for similar instruments and discount rates. A primary price source that best represents trade activity for each market is used to develop observable forward market prices in determining the fair value of these positions. Broker quotes, prices from exchanges, or comparison to executed trades are used to validate and corroborate the primary price source. These price quotations reflect mid-market prices (average of bid and ask) and are obtained from sources believed to provide the most liquid market for the commodity.

Level 3 – This level primarily consists of congestion revenue rights ("CRRs"), which are derivative contracts that trade infrequently with significant unobservable inputs (CAISO CRR auction prices). SCE employs a market valuation approach of utilizing historical CRR prices as a proxy for forward prices. SCE also enters into certain physically settled resource adequacy contracts with a financially settled electricity component ("Fin Toll arrangements"). For these Fin Toll arrangements, SCE uses an income model valuation approach to estimate the significant unobservable inputs (hourly power prices). Edison International Parent and Other does not have any Level 3 assets and liabilities.

Assumptions are made in order to value derivative contracts in which observable inputs are not available. In circumstances where fair value cannot be verified with observable market transactions, it is possible that a different valuation model could produce a materially different estimate of fair value. Modeling methodologies, inputs, and techniques are reviewed and assessed as markets continue to develop and more pricing information becomes available, and the fair value is adjusted when it is concluded that a change in inputs or techniques would result in a new valuation that better reflects the fair value of those derivative contracts. See Note 6 for a discussion of derivative instruments.

SCE

The following table sets forth assets and liabilities of SCE that were accounted for at fair value by level within the fair value hierarchy:

Tableof Contents

1Represents the netting of assets and liabilities under master netting agreements and cash collateral.

2Approximately 70% and 71% of SCE's equity investments were in companies located in the United States at March 31, 2026 and December 31, 2025, respectively.

3Includes corporate bonds, which were diversified by the inclusion of collateralized mortgage obligations and other asset backed securities, of $58 million and $60 million at March 31, 2026 and December 31, 2025, respectively.

4Excludes net payables of $72 million and $251 million at March 31, 2026 and December 31, 2025, respectively, which consist of interest and dividend receivables as well as receivables and payables related to SCE's pending securities sales and purchases.

SCE Fair Value of Level 3

The following table sets forth a summary of changes in SCE's fair value of Level 3 net derivative assets and liabilities:

1Due to regulatory mechanisms, SCE's realized and unrealized gains and losses are recorded as regulatory assets and liabilities.

There were no material transfers into or out of Level 3 during 2026 and 2025.

Tableof Contents

The following table sets forth the significant unobservable inputs used to determine fair value for Level 3 assets and liabilities:

Level 3 Fair Value Uncertainty

For CRRs, increases or decreases in CAISO auction prices would result in higher or lower fair value, respectively.

For Fin Toll arrangements, the fair value measurements are sensitive to the spread between daily high and daily low hourly power prices. Increases or decreases in this spread would result in higher or lower fair value, respectively.

Nuclear Decommissioning Trusts

SCE's nuclear decommissioning trust investments include equity securities, U.S. treasury securities, and other fixed income securities. Equity and treasury securities are classified as Level 1 as fair value is determined by observable market prices in active or highly liquid and transparent markets. The remaining fixed income securities are classified as Level 2. There are no securities classified as Level 3 in the nuclear decommissioning trusts. See Note 10 for more information on nuclear decommissioning trusts.

Edison International Parent and Other

Edison International Parent and Other assets measured at fair value and classified as Level 1 consisted of money market funds of $50 million and $51 million at March 31, 2026 and December 31, 2025, respectively. Assets measured at fair value and classified as Level 2 were immaterial at March 31, 2026 and December 31, 2025. There were no securities classified as Level 3 for Edison International Parent and Other at March 31, 2026 and December 31, 2025.

Fair Value of Debt Recorded at Carrying Value

The carrying value and fair value of Edison International's and SCE's long-term debt (including the current portion of long-term debt) are as follows:

1Carrying value is net of debt issuance costs.

2The fair value of long-term debt is classified as Level 2.

Tableof Contents

Note 5. Debt and Credit Agreements

Long-Term Debt

During the three months ended March 31, 2026, SCE issued the following first and refunding mortgage bonds:

The proceeds were used to repay commercial paper borrowings and for general corporate purposes.

In February 2026, Edison International Parent issued $550 million of 4.80% senior notes due in 2031. The proceeds were used to repay commercial paper and for general corporate purposes.

Credit Agreements and Short-Term Debt

The following table summarizes the status of the credit facilities at March 31, 2026:

1At March 31, 2026, Edison International Parent had $641 million outstanding commercial paper, net of a $2 million discount, at a weighted-average interest rate of 4.37%.

2The aggregate maximum principal amount under the SCE and Edison International Parent revolving credit facilities may be increased up to $4.0 billion and $2.0 billion, respectively, provided that additional lender commitments are obtained.

Term Loan

In February 2026, SCE entered into a term loan agreement to borrow $1.5 billion maturing in March 2027 with a variable interest rate based on SOFR plus 1.00%. The proceeds were used for general corporate and working capital purposes, including the repayment of all borrowings under the $300 million unsecured term loan agreement, dated as of February 11, 2026.

Uncommitted Letters of Credit

SCE entered into agreements with certain lenders for bilateral unsecured standby letters of credit ("SBLC") with a total capacity of $660 million that is uncommitted and supported by reimbursement agreements. The SBLCs are not subject to any collateral or security requirements. At March 31, 2026, SCE had $100 million outstanding under these agreements, which expire between June 2026 and April 2027.

Note 6. Derivative Instruments

Derivative financial instruments are used to manage exposure to commodity price risk resulting from SCE's electricity and natural gas procurement activities. The risks of fluctuating commodity prices are managed in part by entering into forward commodity transactions, including options, swaps, futures, and Fin Toll arrangements. To mitigate credit risk from counterparties in the event of nonperformance, master netting agreements are used whenever possible, and counterparties may be required to pledge collateral depending on the creditworthiness of each counterparty and the risk associated with the transaction.

Certain of SCE's derivative contracts contain credit-risk-related contingent features that require posting of collateral upon a downgrade of SCE's credit ratings to below investment grade by one or more major credit rating agencies. If SCE's credit rating were to fall below investment grade, SCE may be required to post additional collateral to cover derivative liabilities

Tableof Contents

and related outstanding payables. As of March 31, 2026 and December 31, 2025, the fair values of derivative liabilities were immaterial, for which SCE posted collateral of $60 million and $105 million collateral, respectively. If the credit-risk-related contingent features underlying these contracts were triggered on March 31, 2026 and December 31, 2025, SCE would have been required to post an additional $5 million and $3 million of collateral, respectively, most of which is related to outstanding net payables under the contracts.

SCE presents its derivative assets and liabilities, recorded at fair value, on a net basis on its condensed consolidated balance sheets when subject to master netting agreements or similar agreements. Derivative positions are also offset against margin and cash collateral deposits. See Note 4 for a discussion of fair value of derivative instruments.

The following table summarizes the gross and net fair values of SCE's commodity derivative instruments:

1Included in "Other current assets" on SCE's condensed consolidated balance sheets.

2Included in "Other current liabilities" on SCE's condensed consolidated balance sheets.

At March 31, 2026, SCE posted $53 million of cash collateral, of which $34 million was offset against derivative liabilities and $19 million was reflected in "Other current assets" on SCE's condensed consolidated balance sheets. At December 31, 2025, SCE posted $66 million of cash collateral, of which $57 million was offset against derivative liabilities and $9 million was reflected in "Other current assets" on the condensed consolidated balance sheets.

Financial Statement Impact of Derivative Instruments

SCE recognizes realized gains and losses on derivative instruments as purchased power expense and unrealized gains and losses as regulatory assets or liabilities. Both realized and unrealized gains and losses are expected to be recovered from customers and therefore do not affect earnings. Cash flows from derivative activities, including cash collateral, are reported in cash flows from operating activities in SCE's condensed consolidated statements of cash flows.

The following table summarizes the gains/(losses) of SCE's economic hedging activity:

Note 7. Revenue

The following table is a summary of SCE's revenue:

1SCE recorded CPUC revenue based on annual revenue requirement set by a methodology established in the GRC proceeds and FERC revenue authorized through a formula rate. For further information, see Note 1.

2Includes differences between revenues from contracts with customers and authorized levels for certain CPUC and FERC revenues.

At March 31, 2026 and December 31, 2025, SCE's receivables related to contracts from customers were $2.5 billion and $2.7 billion, respectively, which include accrued unbilled revenue of $1.0 billion and $1.2 billion, respectively.

Deferred Revenue

As of March 31, 2026, SCE has deferred revenue of $338 million related to the sale of the use of transfer capability of West of Devers transmission line, of which $13 million and $325 million are included in "Other current liabilities" and "Other deferred credits and other long-term liabilities," respectively, on SCE's condensed consolidated balance sheets. The deferred revenue is amortized straight-line over the period of 30 years starting in 2021.

Note 8. Income Taxes

Effective Tax Rate

The table below provides a reconciliation of income tax expense computed at the federal statutory income tax rate to the income tax provision:

1State taxes in California represents substantially all of the tax effect in this category.

The CPUC requires flow-through ratemaking. For SCE, it includes property-related adjustments, the corporate alternative minimum tax, and other temporary differences which reverse over time. These flow-through items increase or decrease SCE's current authorized revenue requirements in rate cases and give rise to regulatory assets or liabilities for deferred income taxes expected to be realized in future periods. Differences between the amounts authorized in SCE's rate cases, adjusted for balancing and memorandum account activity, and flow-through amounts recorded for financial reporting purposes also result in changes to regulatory assets, with a corresponding impact on the effective tax rate, to the extent recovery in future rates is probable. For further information, see Note 11.

The IRA imposed a corporate alternative minimum tax ("CAMT"), which Edison International and SCE are subject to beginning in 2026. Edison International and SCE expect that any CAMT paid will be creditable against future income taxes.

In addition, under the IRA, SCE expects to generate $158 million investment tax credit in future periods related to utility owned storage projects. The associated tax benefits will be recognized and returned to customers as the credits are utilized.

Tax Disputes

The tax years currently open for examination are 2022 – 2025 for the Internal Revenue Service and 2013 – 2018 and 2021 – 2025 for the Franchise Tax Board.

Future decommissioning costs related to SCE's nuclear assets are expected to be funded from independent decommissioning trusts.

The following table sets forth amortized cost and fair value of the trust investments (see Note 4 for a discussion on fair value of the trust investments):

1As of March 31, 2026 and December 31, 2025, short-term investments included $22 million and $27 million of repurchase agreement payable by financial institutions which earned interest, were fully secured by U.S. Treasury securities, and mature by April 1, 2026 and January 2, 2026, respectively.

2Represents amounts before reduction for deferred tax liabilities on net unrealized gains of $433 million and $455 million as of March 31, 2026 and December 31, 2025, respectively.

Trust fund earnings (based on specific identification) increase the trust fund balance and the ARO regulatory liability. Unrealized holding gains, net of losses, were $1.9 billion and $2.0 billion at March 31, 2026 and December 31, 2025, respectively.

The following table summarizes the gains and losses for the trust investments:

Due to regulatory mechanisms, changes in the assets of the trusts from income or loss items do not materially affect earnings.

Net Regulatory Balancing and Memorandum Accounts

The following table summarizes the significant components of regulatory balancing and memorandum accounts included in the above tables of regulatory assets and liabilities:

1 The GRC-related balancing accounts primarily consist of the base revenue requirement balancing account ("BRRBA"), the vegetation management balancing account ("VMBA"), the Wildfire Risk Mitigation balancing account ("WRMBA") and the risk management balancing account ("RMBA").

The 2025 GRC decision approved the establishment of a two-way Grid Hardening Balancing Account to track the difference between the actual Targeted Undergrounding Program and Rapid Earth Fault Current Limiter costs up to the approved mile limit and the authorized amounts, with spending in excess of 110% of authorized amounts subject to reasonableness review. Additionally, the final decision authorized SCE to establish a memorandum account to track and record capital expenditures above the amounts authorized to support SCE's grid readiness for future transportation electrification demand, with cost recovery subject to reasonableness review.

2 The wildfire risk mitigation and insurance regulatory assets represent wildfire-related costs that are probable of future recovery from customers, subject to a reasonableness review. The Wildfire Expense Memorandum Account ("WEMA") is used to track incremental wildfire insurance costs and uninsured wildfire-related financing, legal and claim costs related to the Other Wildfire Events that SCE believes are probable of recovery. See Note 12 for further details. The Wildfire Mitigation Plan Memorandum Account is used to track costs incurred to implement SCE's wildfire mitigation plan that are not currently reflected in SCE's revenue requirements. The Fire Risk Mitigation Memorandum Account is used to track costs related to the reduction of fire risk that are incremental to costs approved for recovery in SCE's GRCs that are not tracked in any other wildfire-related memorandum account.

3 The wildfire and drought restoration regulatory assets represent restoration costs that are recorded in a Catastrophic Event Memorandum Account.

Note 12. Commitments and Contingencies

Indemnities

Edison International and SCE have agreed to provide indemnification through contracts entered into in the normal course of business. These are primarily indemnifications against adverse litigation outcomes in connection with underwriting agreements, indemnities for specified environmental liabilities and income taxes or other contractual arrangements. Edison International's and SCE's obligations under these agreements may or may not be limited in terms of time and/or amount, and in some instances Edison International and SCE may have recourse against third parties. Edison International and SCE have not recorded a liability related to these indemnities. The overall maximum amount of the obligations under these indemnifications cannot be reasonably estimated.

Contingencies

In addition to the matters disclosed in these Notes, Edison International and SCE are involved in other legal, tax, and regulatory proceedings before various courts and governmental agencies regarding matters arising in the ordinary course of business, all of which are subject to uncertainties. Edison International and SCE believe the outcome of each of these other proceedings will not materially affect its financial position, results of operations and cash flows. Legal costs expected to be incurred by Edison International and SCE in connection with loss contingencies are expensed as incurred.

Southern California Wildfires and Mudslides

Unprecedented weather conditions in California due to climate change and greater concentrations of residents in high-fire risk areas, among other things, have contributed to wildfires, including those where SCE's equipment has been alleged to be associated with the fire's ignition, that have caused loss of life and substantial damage in SCE's service area.

Numerous claims related to wildfire events have been initiated against SCE and Edison International. Edison International and SCE have, or may, incur material losses in connection with the 2017/2018 Wildfire/Mudslide Events, the Other Wildfire Events that are described below, and the January 2025 Eaton Fire. Of the Other Wildfire Events described below, only the 2017 Creek Fire ignited prior to the adoption of AB 1054 in July 2019. SCE's equipment has been, and may further be, alleged to be associated with other wildfires that have originated in Southern California, and SCE's service area remains susceptible to additional wildfire activity.

Liability Overview

The extent of legal liability for wildfire-related damages in actions against utilities depends on a number of factors, including whether the utility substantially caused or contributed to the damages and whether parties seeking recovery of damages will be required to show negligence in addition to causation. California courts have previously found utilities to be strictly liable for property damage along with associated interest and attorneys' fees, regardless of fault, by applying the theory of inverse condemnation when a utility's facilities were determined to be a substantial cause of a wildfire that caused the property damage. If inverse condemnation is held to be inapplicable to SCE in connection with a wildfire, SCE still could be held liable for property damages and associated interest if the property damages were found to have been proximately caused by SCE's negligence. If SCE were to be found negligent, SCE could also be held liable for, among other things, fire suppression costs, business interruption losses, evacuation costs, clean-up costs, medical expenses, and personal injury/wrongful death claims, including claims for non-economic damages. Additionally, SCE could potentially be subject to fines and penalties for alleged violations of CPUC rules and state laws investigated in connection with the ignition of a wildfire.

While investigations into the cause of a wildfire event are conducted by one or more fire agencies, fire agency findings do not determine legal causation of or assign legal liability for a wildfire event. Final determinations of legal causation and liability for wildfire events, including determinations of whether SCE was negligent, would only be made during lengthy and complex litigation processes, and settlements may be reached before determinations of legal liability are ever made. Even when investigations are still pending or legal liability is disputed, an assessment of likely outcomes, including through future settlement of claims, may require estimated losses to be accrued under accounting standards.

Estimates and Assumptions

Each reporting period, management reviews its loss estimates for remaining alleged and potential claims related to wildfire events. The process for estimating losses associated with alleged and potential wildfire-related claims requires management to exercise significant judgment based on a number of assumptions and subjective factors, including, but not limited to: volume of claims, damages asserted and associated loss, opinions of counsel regarding litigation risk, the status of and developments in the course of litigation, prior experience litigating and settling wildfire litigation claims, the amount of insurance that may offset losses, and estimating contributory liabilities from third parties who may be responsible for portions of loss.

Estimated losses for wildfire litigation are based on a number of assumptions and are subject to change as additional information becomes available. As additional information becomes available, management's estimates and assumptions regarding the causes and financial impact of wildfire events may change. Actual losses incurred may be higher or lower than estimated based on several factors, including the uncertainty in estimating damages that have been or may be alleged and uncertainty in estimating settlement outcomes. For instance, SCE receives additional information with respect to damages claimed as claims mediation and trial processes progress. Other factors that can cause actual losses incurred to be higher or lower than estimated include the ability to reach settlements and the outcomes of settlements reached through claims mediation processes, uncertainties related to the impact of outcomes of wildfire litigation against other parties and increasingly negative jury sentiments in general litigation, uncertainties related to the sufficiency of insurance held by plaintiffs and potential plaintiffs, uncertainties related to litigation processes, including whether potential plaintiffs will ultimately pursue claims, uncertainty as to the legal and factual determinations to be made during litigation, including uncertainty as to the contributing causes of wildfire events, and the uncertainty as to how these factors impact future settlements.

Litigation

2017/2018 Wildfire/Mudslide Events

Wildfires in SCE's service area in December 2017 and November 2018 caused loss of life, substantial damage to both residential and business properties, and service outages for SCE customers. The investigating government agencies, the Ventura County Fire Department ("VCFD") and CAL FIRE, have determined that the largest of the 2017 fires in SCE's service area originated on December 4, 2017, in the Anlauf Canyon area of Ventura County, followed shortly thereafter by a second fire that originated near Koenigstein Road in the City of Santa Paula. According to CAL FIRE, the Thomas and Koenigstein Fires, collectively, burned over 280,000 acres, destroyed or damaged an estimated 1,343 structures and resulted in two confirmed fatalities. The largest of the November 2018 fires in SCE's service area, the Woolsey Fire, originated in Ventura County. According to CAL FIRE, the Woolsey Fire burned almost 100,000 acres, destroyed an estimated 1,643 structures, damaged an estimated 364 structures and resulted in three confirmed fatalities. Four additional fatalities are alleged to have been associated with the Woolsey Fire.

Multiple lawsuits related to the Thomas and Koenigstein Fires and the Woolsey Fire have been initiated against SCE and Edison International. Some of the Thomas and Koenigstein Fires lawsuits claim that SCE and Edison International have responsibility for the damages caused by debris flows and flooding in Montecito and surrounding areas in January 2018 based on a theory alleging that SCE has responsibility for the Thomas and/or Koenigstein Fires and further alleging that the Thomas and/or Koenigstein Fires proximately caused the Montecito Mudslides. According to Santa Barbara County initial reports, the Montecito Mudslides destroyed an estimated 135 structures, damaged an estimated 324 structures, and resulted in 21 confirmed fatalities, with two additional fatalities presumed but not officially confirmed.

The lawsuits related to the 2017/2018 Wildfire/Mudslide Events naming SCE as a defendant have been filed by three categories of plaintiffs: individual plaintiffs, subrogation plaintiffs and public entity plaintiffs. A number of the lawsuits also name Edison International as a defendant and some of the lawsuits were filed as purported class actions. As of April 21, 2026, in addition to the outstanding claims of approximately 70 individual plaintiffs, there were alleged and potential claims of certain public entity plaintiffs, including CAL OES, outstanding. SCE has settled all fire suppression claims and subrogation plaintiffs' claims related to the 2017/2018 Wildfire/Mudslide Events, except for one indemnification claim.

In January 2019, SCE filed a cross-complaint against certain local public entities alleging that failures by these entities, such as failure to adequately plan for flood hazards and build and maintain adequate debris basins, roads, bridges and other channel crossings, among other things, caused, contributed to or exacerbated the losses that resulted from the Montecito Mudslides. Once SCE has settled all individual plaintiff claims in the TKM litigation that impact the corresponding cross-claims, SCE intends to appeal certain procedural issues to maintain its ability to pursue the cross-claims.

The litigation could take a number of years to be completely resolved because of the complexity of the matters and number of plaintiffs. As of April 21, 2026, SCE has entered into settlements with approximately 13,800 individual plaintiffs in the 2017/2018 Wildfire/Mudslide Events litigation. The statutes of limitations for individual plaintiffs in the 2017/2018 Wildfire/Mudslide Events have expired.

In October 2021, SCE and the SED executed an agreement to resolve the SED's investigations into the 2017/2018 Wildfire/Mudslide Events and three other 2017 wildfires for, among other things, aggregate costs of $550 million. The $550 million in costs was composed of a $110 million fine to be paid to the State of California General Fund, $65 million of shareholder-funded safety measures, and an agreement by SCE to waive its right to seek cost recovery in CPUC-jurisdictional rates for $125 million and $250 million of third-party uninsured claims payments (and related financing costs) in the TKM litigation and the Woolsey Fire litigation, respectively. The SED Agreement provides that SCE may, on a permanent basis, exclude from its ratemaking capital structure any after-tax charges to equity or debt borrowed to finance costs incurred under the SED Agreement. The SED Agreement also imposes other obligations on SCE, including reporting requirements and safety-focused studies. SCE did not admit imprudence, negligence, or liability with respect to the 2017/2018 Wildfire/Mudslide Events in the SED Agreement.

Other Wildfire Events

SCE has settled substantially all of the claims that were filed against it related to the 2017 Creek Fire, the 2020 Bobcat Fire, and the 2020 Silverado Fire and does not expect to incur additional losses in excess of amounts accrued for each such fire. While Edison International and SCE may incur material losses in excess of the amounts accrued for certain of the Other Wildfire Events, Edison International and SCE expect that additional losses incurred in connection with any such fire, will be covered by insurance, subject to self-insured retentions and co-insurance, and expect that any such additional losses after expected recoveries from insurance and through electric rates will not be material.

2019 Saddle Ridge Fire

The "Saddle Ridge Fire," originated in Los Angeles County in October 2019 and burned approximately 9,000 acres, destroyed an estimated 19 structures, damaged an estimated 88 structures, and resulted in one fatality and injuries to eight firefighters. In August 2023, SCE received a signed report of investigation from the LAFD, in which the LAFD stated with respect to the Saddle Ridge Fire that the cause of ignition was unintentional, the form of heat was undetermined, the item first ignited was undetermined and the material type first ignited was undetermined. The LAFD report noted that no other competent ignition sources other than SCE's transmission lines were found in the specific origin area of the Saddle Ridge Fire. The SED conducted an investigation with respect to the Saddle Ridge Fire and issued an undated report listing alleged violations of CPUC General Orders by SCE and noting that the alleged violations, under certain circumstances, could have led to a fire ignition. Multiple lawsuits related to the Saddle Ridge Fire were filed by plaintiffs naming SCE as defendant. An inverse condemnation bench trial in the Saddle Ridge Fire litigation has been set for October 2026. SCE has accrued charges for potential losses relating to the Saddle Ridge Fire.

2022 Coastal Fire

The "Coastal Fire" originated in Orange County in May 2022 and burned approximately 200 acres. The Orange County Fire Authority ("OCFA") has reported that the Coastal Fire destroyed 20 residential structures and damaged 11 residential structures. Two firefighters also reportedly sustained minor injuries. In addition, fire authorities have estimated suppression costs at approximately $3 million. While SCE's investigation remains ongoing, SCE's information reflects that a SCE circuit in the area experienced an anomaly (a relay) approximately 2 minutes prior to the reported time of the fire. An investigation into the cause of the Coastal Fire was led by the OCFA. The OCFA has retained SCE equipment in connection with its investigation. In September 2024, SCE received a report of investigation from the OCFA, in which the OCFA finds that the Coastal Fire was unintentionally caused by sparks from overhead SCE electrical equipment igniting vegetation under the equipment. The SED is conducting an investigation with respect to the Coastal Fire and issued a notice of violation in 2025. SCE has settled subrogation plaintiff claims and claims brought by the County of Orange related to the Coastal Fire. Individual plaintiffs have also filed complaints against SCE related to the Coastal Fire. As of April 21, 2026, no trials are scheduled in the Coastal Fire litigation. SCE expects to obtain and review additional information and materials in the possession of third parties during the course of its internal reviews and the litigation process. SCE has accrued charges for potential losses relating to the Coastal Fire.

2022 Fairview Fire

The "Fairview Fire" originated in Riverside County in September 2022 and burned approximately 28,000 acres. CAL FIRE has reported that the Fairview Fire destroyed 22 residential structures, damaged five residential structures, and destroyed or damaged 17 minor structures. CAL FIRE also reported two civilian fatalities, one civilian injury and two injuries to responding fire personnel. In addition, fire authorities have estimated suppression costs at $39 million. While SCE's investigation remains ongoing, SCE's information reflects that an SCE circuit in the area experienced an anomaly (a relay) approximately 8 minutes prior to the reported start time of the fire. In November 2023, SCE received a report of investigation conducted by CAL FIRE, in which CAL FIRE finds that the Fairview Fire was caused when a sagging SCE electrical conductor came in contact with a communication line, causing sparks to fall and ignite surrounding vegetation. In March 2025, the SED issued a citation for approximately $2 million for alleged violations of the SED's rules and regulations, including SCE's failure post-fire to comply with clearance requirements with respect to its electrical conductor. SCE has settled subrogation plaintiff claims related to the Fairview Fire. A jury trial in the Fairview Fire individual plaintiff litigation has been set for June 2026. SCE expects to obtain and review additional information and materials in the possession of third parties during the course of its internal reviews and the litigation process. SCE has accrued charges for potential losses relating to the Fairview Fire.

2025 Eaton Fire

In January 2025, several wind-driven wildfires impacted portions of SCE's service area, causing loss of life, substantial damage to both residential and business properties and service outages for SCE customers. One of the largest of these wildfires, the "Eaton Fire," ignited in SCE's service area in Los Angeles County and spread due to a number of contributing factors under conditions of an extreme Santa Ana windstorm.

CAL FIRE has reported that the Eaton Fire burned approximately 14,000 acres and resulted in 18 civilian fatalities and 9 fire personnel injuries/illnesses. An additional fatality has also been reported to be attributed to the Eaton Fire. In addition, according to preliminary information provided by CAL FIRE, the Eaton Fire destroyed approximately 6,018 single residence structures, 3,146 other minor structures, 96 multiple residences and 158 mixed commercial/residential and nonresidential commercial structures; and damaged approximately 750 residential structures, 260 other minor structures, 28 multiple residences and 35 mixed commercial/residential and nonresidential commercial structures. Fire authorities have estimated suppression costs at approximately $100 million.

Tableof Contents

The Los Angeles County Fire Department is leading the investigation into the origin and cause of the Eaton Fire, with the assistance of CAL FIRE, and has identified a preliminary area of origin of the fire. SCE has transmission facilities in the preliminary area of origin and the SED is conducting an investigation with respect to the Eaton Fire. Edison International and SCE are also aware of an ongoing investigation by the Los Angeles District Attorney's Office of the Eaton Fire for the purpose of determining whether any criminal violations have occurred. SCE could be subject to material fines, penalties, or restitution if it is determined that it failed to comply with applicable laws and regulations. SCE is not aware of any basis for felony liability with regards to the Eaton Fire.

Multiple lawsuits related to the Eaton Fire have been initiated against SCE. A number of the lawsuits also name Edison International as a defendant and some of the lawsuits were filed as purported class actions. As of April 21, 2026, SCE was aware of approximately 2,000 lawsuits related to the Eaton Fire: representing lawsuits by approximately 30,000 individual plaintiffs and also lawsuits by subrogation plaintiffs and public entity plaintiffs. A bellwether jury trial in the Eaton Fire litigation has been set for January 2027.

SCE's internal review into the facts and circumstances of the Eaton Fire is complex and ongoing. SCE's review includes ongoing inspections of its facilities and records and of third-party information and testing. While SCE has not conclusively determined that its equipment caused the ignition of the Eaton Fire, a viable explanation is that a de-energized idle SCE transmission facility in the preliminary area of origin was associated with the ignition of the fire and 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 and is pursuing settlement of claims through its Wildfire Recovery Compensation Program.

SCE has entered into settlements with insurance claimants and individual and business claimants under its Wildfire Recovery Compensation Program related to the Eaton Fire. In total, as of March 31, 2026, SCE had recorded $1.3 billion in losses related to these settlements. SCE also recorded expected recoveries from customer-funded self-insurance of $917 million, from the Wildfire Fund of $295 million, and through FERC electric rates of $70 million. See "—Settlement of Claims," "—Accrued Losses" and "—Recoveries" below for further details.

No admission of wrongdoing or liability was made in reaching the settlements described above and the claimants party to the settlements have agreed to release SCE and Edison International from all claims and potential claims related to or arising from the Eaton Fire.

In light of pending litigation, it is probable that Edison International and SCE will incur additional material losses in connection with the Eaton Fire. Given, among other things, the complexities associated with estimating damages, the large number and varying types of claims and the interrelationship among the claims, uncertainties related to the sufficiency of insurance held by plaintiffs and potential plaintiffs, and uncertainties related to litigation processes and the Wildfire Recovery Compensation Program, Edison International and SCE are currently unable to reasonably estimate a range of losses that may be incurred in connection with the Eaton Fire.

Settlement of Claims

The following table presents settlements paid.

Edison International and SCE have not admitted wrongdoing or liability as part of any settlements related to the 2017/2018 Wildfire/Mudslide Events, the Other Wildfire Events, or the Eaton Fire. SCE continues to explore reasonable settlement opportunities with plaintiffs in outstanding wildfire litigation.

Accrued Losses

The following table presents changes in accrued losses since December 31, 2025.

Edison International's and SCE's condensed consolidated balance sheets included fixed payments to be made under settlements and accrued estimated losses presented in the tables below.

1At March 31, 2026, current liabilities related to 2017/2018 Wildfire/Mudslide Events consisted of $6 million of settlements executed and $26 million of short-term payables under the SED Agreement. At December 31, 2025, current liabilities related to 2017/2018 Wildfire/Mudslide Events consisted of $6 million of settlements executed and $25 million of short-term payables under the SED Agreement.

2At March 31, 2026, long-term wildfire-related claims related to 2017/2018 Wildfire/Mudslide Events consisted of $14 million of long-term payables under the SED Agreement and $137 million of estimate of expected losses for remaining alleged and potential claims. At December 31, 2025, long-term wildfire-related claims related to 2017/2018 Wildfire/Mudslide Events consisted of $17 million of long-term payables under the SED Agreement and $144 million of estimate of expected losses for remaining alleged and potential claims.

Management reviews its loss estimates for remaining alleged and potential claims related to wildfire litigation quarterly. Edison International and SCE have accrued their best estimate of expected losses for remaining alleged and potential claims related to the 2017/2018 Wildfire/Mudslide Events and at the low end of the estimated range of reasonably possible losses for the Other Wildfire Events as no amount within the range of reasonably possible losses for the Other Wildfire Events appears, at this time, to be a better estimate than any other amount within the range.

Edison International and SCE may incur a material loss in excess of amounts accrued in connection with the remaining alleged and potential claims related to the 2017/2018 Wildfire/Mudslide Events and Other Wildfire Events. Due to the number of uncertainties and possible outcomes related to the 2017/2018 Wildfire/Mudslide Events and Other Wildfire Events litigation, Edison International and SCE cannot estimate the upper end of the range of reasonably possible losses that may be incurred in connection with the 2017/2018 Wildfire/Mudslide Events or the Other Wildfire Events. The estimated losses for the 2017/2018 Wildfire/Mudslide Events do not include estimates of potential losses related to certain potential public entity plaintiff claims, including CAL OES's claim in the TKM litigation, for which the statute of limitations has been tolled, as losses from these alleged and potential claims are not estimable at this time.

While SCE recorded losses related to settlements that have been entered into related to the Eaton Fire, Edison International and SCE are currently unable to reasonably estimate a range of losses that may be incurred in connection with the Eaton Fire.

Tableof Contents

For the three months ended March 31, 2026 and 2025, SCE recorded wildfire-related claims, net of expected recoveries as follows:

1For the three months ended March 31, 2025, EIS incurred $50 million insurance expenses, which consisted of $47 million of wildfire claims and $3 million of related legal costs.

In total, through March 31, 2026, SCE has recorded losses of $12.3 billion, expected recoveries from insurance and third parties of $2.8 billion, expected recoveries through electric rates of $3.6 billion, expected recoveries from customer-funded wildfire self-insurance of $0.9 billion, and expected recoveries from the Wildfire Fund of $0.3 billion related to the 2017/2018 Wildfire/Mudslide Events, the Other Wildfire Events, and the Eaton Fire. The after-tax net charges to earnings recorded through March 31, 2026, have been $3.4 billion.

Recoveries

Wildfire-related losses that Edison International or SCE incurs may be recovered from insurance, including customer-funded wildfire self-insurance, third-parties, the Wildfire Fund and through electric rates. Fines and penalties incurred in connection with a wildfire are not recoverable from insurance, the Wildfire Fund or through electric rates.

The following tables summarize expected recoveries from insurance and third parties, the Wildfire Fund, and through electric rates for the Other Wildfire Events and the Eaton Fire as of March 31, 2026 and December 31, 2025. For recoveries related to the 2017/2018 Wildfire/Mudslide Events, see below discussion in "—Recoveries through Electric Rates."

Tableof Contents

1As of March 31, 2026, no amounts have been recovered from the Wildfire Fund.

Recoveries through Insurance

Edison International and SCE record a receivable for insurance recoveries when recovery of a recorded loss is determined to be probable. SCE has exhausted expected insurance recoveries related to the 2017/2018 Wildfire/Mudslide Events. Expected recoveries from insurance recorded for the Other Wildfire Events are supported by SCE's insurance coverage for multiple policy years. SCE exhausted self-insurance recoveries available for losses related to the Eaton Fire as a result of costs incurred and settlements entered into as of February 11, 2026.

For events that occurred in 2017 and early 2018, principally the Thomas and Koenigstein Fires and Montecito Mudslides, SCE had $1.0 billion of wildfire-specific insurance coverage, subject to a self-insured retention of $10 million per occurrence. For the Woolsey Fire, SCE had an additional $1.0 billion of wildfire-specific insurance coverage, subject to a self-insured retention of $10 million per occurrence. SCE recovered $2.0 billion from its insurance carriers in relation to the claims related to the 2017/2018 Wildfire/Mudslide Events and $18 million related to the Creek Fire. Additional insurance was not available for the Creek Fire because wildfire insurance for the period in which the fire was ignited was almost fully exhausted as a result of the TKM litigation.

SCE has approximately $1.2 billion of wildfire-specific insurance coverage for events that occurred during the period June 1, 2019 through June 30, 2020, subject to up to $165 million of co-insurance and self-insured retention, which resulted in net coverage of approximately $1.0 billion.

SCE has approximately $1.0 billion of wildfire-specific insurance coverage for events that occurred during the period July 1, 2020 through June 30, 2021, subject to up to $130 million of self-insured retention and co-insurance per fire, which results in net coverage of approximately $870 million.

SCE has approximately $1.0 billion of wildfire-specific insurance coverage for events that occurred during the period July 1, 2021 through June 30, 2022, subject to up to $163 million of self-insured retention and co-insurance per fire, which resulted in net coverage of approximately $837 million.

SCE has approximately $1.0 billion of wildfire-specific insurance coverage for events that occurred during the period July 1, 2022 through June 30, 2023, subject to up to $63 million of self-insured retention and co-insurance per fire, which results in net coverage of approximately $937 million.

SCE's wildfire insurance expense for the July 1, 2022 through June 30, 2023 policy period was approximately $450 million, of which $357 million was paid to commercial insurance carriers (commercial insurance carriers other than EIS are referred to herein as "Third-Party Commercial Insurers"). The difference between the Third-Party Commercial

Insurer cost and total cost for the July 1, 2022 through June 30, 2023 policy period was paid in premiums to EIS (see Note 16 for further information). Wildfire insurance premiums paid for the July 1, 2022 through June 30, 2023 policy period are being recovered through customer rates. As a result of an EIS insurance policy amendment, in the first quarter of 2025, EIS recorded a $50 million wildfire insurance expense (by utilizing the premiums already collected as discussed above), and SCE recorded the corresponding insurance recovery from EIS, which reduced expected WEMA recoveries. On the Edison International condensed consolidated statements of income, the EIS insurance expense is eliminated with SCE's insurance recovery from EIS.

In May 2023, the CPUC allowed SCE to establish an expanded self-insurance program for wildfire-related costs that will be funded through CPUC-jurisdictional rates, in lieu of obtaining wildfire liability insurance from the commercial insurance market. Beginning on July 1, 2023, SCE implemented its customer-funded wildfire self-insurance program. In 2023 and 2024, SCE collected $150 million and $300 million, respectively, through CPUC-jurisdictional rates in support of SCE's customer-funded wildfire self-insurance program.

In July 2024, the CPUC issued a decision in the 2025 GRC proceeding authorizing this self-insurance framework to continue through at least 2028, supporting a self-insurance fund of up to $1.0 billion per policy year. From 2025 through 2028, approximately $300 million would be collected annually, subject to revenue requirement adjustments, until a total available self-insurance accrual amount of $1.0 billion is achieved. In 2025, SCE collected $300 million through CPUC-jurisdictional rates in support of its customer-funded wildfire self-insurance program.

SCE has $1.0 billion of customer-funded self-insurance coverage available for wildfires ignited between January 1, 2025 and December 31, 2025, primarily the Eaton Fire, subject to up to a maximum shareholder contribution of $12.5 million.

SCE has $1.0 billion of customer-funded self-insurance coverage available for wildfires ignited between January 1, 2026 and December 31, 2026 under its self-insurance program described below, subject to up to a maximum possible shareholder contribution of $12.5 million. SCE's self-insurance program meets its obligation to maintain reasonable insurance coverage under the California Wildfire Legislation for the January 1, 2026 through December 31, 2026 period.

When losses are accrued for wildfire-related claims for wildfires that occur between July 1, 2023 and the end of 2028, customer rates will be increased in subsequent years, as needed, to allow for full recovery of the amounts accrued up to $1.0 billion per policy year, subject to a shareholder contribution of 2.5% of any self-insurance costs ultimately paid exceeding $500 million in any policy year, up to a maximum contribution of $12.5 million per policy year. As a result of accrued losses related to the Eaton Fire, in April 2026 the CPUC approved SCE's request to adjust revenue requirements to be collected from customers from $274 million to $650 million for 2026. As of March 31, 2026, SCE collected $68 million through CPUC-jurisdictional rates for SCE's customer-funded wildfire self-insurance program and is authorized to collect an additional $429 million through December 31, 2026 with the remaining $153 million expected to be collected in 2027, subject to regulatory balancing account adjustments.

Recoveries through Electric Rates

Under accounting standards for rate-regulated enterprises, SCE defers costs as regulatory assets in the period it concludes that such costs are probable of future recovery in electric rates. The CPUC and FERC may not allow SCE to recover uninsured losses through electric rates, including by FERC requiring refund of amounts recovered, if it is determined that such losses were not prudently incurred. SCE utilizes objectively determinable evidence to form its view on the probability of future recovery and refund.

CPUC recoveries pre-AB 1054

The only precedent in which a California investor-owned utility sought recovery for uninsured wildfire claims related costs and the CPUC made a prudency determination is SDG&E's requests for cost recovery related to 2007 wildfire activity, where the FERC allowed recovery of all FERC-jurisdictional wildfire claims related costs while the CPUC rejected recovery of all CPUC-jurisdictional wildfire claims related costs based on a determination that SDG&E did not meet the CPUC's prudency standard ("SDG&E Decision"). The SDG&E Decision is evidence of a California investor-owned utility seeking recovery for uninsured wildfire-related costs and FERC allowing recovery of all FERC-jurisdictional wildfire-related costs while the CPUC rejected recovery of all CPUC-jurisdictional wildfire-related costs based on a determination that the utility did not meet the CPUC's prudency standard.

Under the TKM Settlement Agreement approved by the CPUC in January 2025, SCE is authorized to recover 60%, or approximately $1.6 billion, of approximately $2.7 billion of losses, consisting of approximately $1.3 billion of uninsured claims paid as of May 31, 2024 and $0.3 billion of associated costs, composed of legal fees and financing costs incurred as of May 31, 2024 and estimated ongoing financing costs. SCE is also authorized to recover 60% of claims paid and related costs incurred after May 31, 2024, other than for $125 million of uninsured claims and related financing costs which SCE waived its right to seek recovery of under the SED Agreement. As a result, in 2025, SCE recorded a regulatory asset for recoveries authorized under the TKM Settlement Agreement. SCE was also authorized to recover approximately

Tableof Contents

$55 million of approximately $65 million in incremental restoration costs, inclusive of operations and maintenance expenses, incurred related to the Thomas and Koenigstein Fires. Additionally, SCE recorded $50 million of shareholder-funded wildfire mitigation expenses.

Under the Woolsey Settlement Agreement approved by the CPUC in December 2025, SCE is authorized to recover 35%, or approximately $2.0 billion, of approximately $5.6 billion of losses, consisting of approximately $1.6 billion of uninsured claims paid as of May 31, 2025, and $0.4 billion of costs, comprised of legal costs paid as of May 31, 2025, and estimated ongoing financing costs. SCE is also authorized to recover 35% of losses paid after May 31, 2025. SCE’s requests for recovery exclude $250 million of uninsured claims and related financing costs which SCE waived its right to seek recovery of under the SED Agreement. As a result, in 2025, SCE recorded a regulatory asset for recoveries authorized under the Woolsey Settlement Agreement. SCE was also authorized to recover approximately $71 million of approximately $84 million in incremental restoration costs, inclusive of operations and maintenance expenses, incurred related to the Woolsey Fire.

In the Woolsey Settlement Agreement, SCE also waived its right to seek recovery of uninsured losses tracked in a Wildfire Expense Memorandum Account and incurred in connection with fires that ignited prior to July 12, 2019, the date AB 1054 was adopted, including the Creek Fire. SCE estimates that the waived pre-AB 1054 losses are approximately $157 million.

CPUC recoveries post-AB 1054

The SDG&E Decision was prior to the adoption of AB 1054 on July 12, 2019, after which date AB 1054 clarified that the CPUC must find a utility to be prudent if the utility's conduct related to the ignition was consistent with actions that a reasonable utility would have undertaken in good faith under similar circumstances, at the relevant point in time, and based on the information available at that time. Further, utilities with a valid safety certification at the time of the relevant wildfire will be presumed to have acted prudently related to a wildfire ignition unless a party in the cost recovery proceeding creates serious doubt as to the reasonableness of the utility's conduct, at which time, the burden shifts back to the utility to prove its conduct was prudent.

The Eaton Fire and each of the Other Wildfire Events discussed above, with the exception of the Creek Fire, was ignited after July 12, 2019, and SCE has held a valid safety certification since July 15, 2019. While a California investor-owned utility has not yet received a decision on a prudency review related to recovery for uninsured claims and other costs related to wildfires ignited after the adoption of AB 1054, SCE believes that for fires ignited after July 12, 2019, and for investor-owned utilities holding a safety certification at the time of the fire, the CPUC will apply a standard of review similar to that applied by the FERC which presumes all costs requested by an investor-owned utility are reasonable and prudent unless serious doubt as to the reasonableness of the utility's conduct is created. As such, SCE has concluded, at this time, that uninsured CPUC-jurisdictional wildfire-related costs related to wildfire events occurring after the adoption of AB 1054 that it has deferred as regulatory assets are probable of recovery through electric rates. SCE will continue to evaluate the probability of recovery based on available evidence, including regulatory decisions. Evidence that SCE may consider in its evaluation includes, among other factors, its status as a holder of a valid safety certification, the legislative intent of AB 1054, facts and other evidence known to date related to the ignition, and any regulatory decisions on wildfire cost recovery, including those illustrating the interpretation and/or application of the prudency framework under the California Wildfire Legislation. The CPUC may not allow SCE to recover uninsured losses related to the wildfire events through electric rates if it is determined that such losses were not prudently incurred.

FERC recoveries

Through the operation of its FERC Formula Rate, and based upon the precedent established in SDG&E's recovery of FERC-jurisdictional wildfire-related costs, SCE believes it is probable it will recover its FERC-jurisdictional costs related to the 2017/2018 Wildfire/Mudslide Events, the Other Wildfire Events, and the Eaton Fire. In total, as of March 31, 2026, SCE's recoveries received since inception, and expected to be received through FERC electric rates, were $440 million related to the 2017/2018 Wildfire/Mudslide Events, $23 million related to the Other Wildfire Events, and $70 million related to the Eaton Fire. FERC recoveries are subject to refund, and SCE will continue to evaluate the probability of recovery and refund obligations of FERC-jurisdictional costs related to the 2017/2018 Wildfire/Mudslide Events, the Other Wildfire Events, and the Eaton Fire based on available evidence, including any FERC decisions to allow or disallow recovery of FERC-jurisdictional wildfire-related costs based on a state regulator's decision on whether to permit recovery of related costs.

Recoveries through the Wildfire Fund

SCE has advised the administrator of the Wildfire Fund that it anticipates seeking reimbursement of eligible claims arising from the Eaton Fire from the Initial Account and the administrator has confirmed that the Eaton Fire is a "covered wildfire" for purposes of accessing the Initial Account. SCE will be reimbursed for losses incurred in excess of $1.0 billion for eligible claims for third-party damages related to the Eaton Fire from the Initial Account, subject to approval of the fund

Tableof Contents

administrator and the Initial Account's claims-paying capacity. The fund administrator has reported that, as of September 30, 2025, the fund's claim paying capacity for the Eaton Fire exceeds $21 billion. Edison International and SCE record a receivable for recoveries from the Wildfire Fund when recovery of a recorded loss from the fund is determined to be probable.

SCE will file an application with the CPUC for review of its costs and expenses related to the Eaton Fire after it has resolved all or, if authorized by the CPUC, substantially all third-party damage claims related to the fire, or upon earlier request of the fund administrator. The CPUC will determine the prudency of SCE's ignition-related conduct in a formal proceeding. If the CPUC finds that SCE's conduct related to the ignition of the Eaton Fire was not prudent, SCE will be required to reimburse the Initial Account only for amounts disallowed by the CPUC up to the applicable Liability Cap of approximately $4.3 billion, unless the fund administrator finds that SCE's actions or inactions relative to the ignition of the Eaton Fire constitute conscious or willful disregard of the rights and safety of others, in which case SCE will be required to reimburse the Initial Account for withdrawn amounts that the CPUC disallowed. For further discussion of SCE's reimbursement obligations see Note 1.

SCE will be able to seek recovery of prudently incurred uninsured wildfire costs not covered by the Initial Account, assessed under the prudency standard clarified under AB 1054, through electric rates.

Environmental Remediation

SCE records its environmental remediation liabilities when site assessments and/or remedial actions are probable and a range of reasonably likely cleanup costs can be estimated. SCE reviews its sites and measures the liability quarterly, by assessing a range of reasonably likely costs for each identified site using currently available information, including existing technology, presently enacted laws and regulations, experience gained at similar sites, and the probable level of involvement and financial condition of other potentially responsible parties. These estimates include costs for site investigations, remediation, operation and maintenance, monitoring, and site closure. Unless there is a single probable amount, SCE records the low end of this reasonably likely range of costs (reflected in "Other long-term liabilities") at undiscounted amounts as timing of cash flows is uncertain.

At March 31, 2026, SCE's recorded estimated minimum liability to remediate its 19 identified material sites (sites with a liability balance at March 31, 2026, in which the upper end of the range of expected costs is at least $1 million) was $217 million, including $147 million related to San Onofre. In addition to these sites, SCE also has 14 immaterial sites with a liability balance as of March 31, 2026, for which the total minimum recorded liability was $5 million. Of the $222 million total environmental remediation liability for SCE, $212 million has been recorded as a regulatory asset. SCE expects to recover $34 million through an incentive mechanism that allows SCE to recover 90% of its environmental remediation costs at certain sites (SCE may request to include additional sites in this mechanism) and $178 million through proceedings that allow SCE to recover up to 100% of the costs incurred at certain sites through customer rates. SCE's identified sites include several sites for which there is a lack of currently available information, including the nature and magnitude of contamination, and the extent, if any, that SCE may be held responsible for contributing to any costs incurred for remediating these sites. Thus, no reasonable estimate of cleanup costs can be made for these sites.

The ultimate costs to clean up SCE's identified sites may vary from its recorded liability due to numerous uncertainties inherent in the estimation process, such as: the extent and nature of contamination; the scarcity of reliable data for identified sites; the varying costs of alternative cleanup methods; developments resulting from investigatory studies; the possibility of identifying additional sites; and the time periods over which site remediation is expected to occur. SCE believes that, due to these uncertainties, it is reasonably possible that cleanup costs at the identified material sites and immaterial sites could exceed its recorded liability by up to $98 million and $2 million, respectively. The upper limit of this range of costs was estimated using assumptions least favorable to SCE among a range of reasonably possible outcomes.

SCE expects to clean up and mitigate its identified sites over a period of up to approximately 35 years, though some sites may require a longer time period. Remediation costs for each of the next five years are expected to range from $7 million to $21 million. Costs incurred for the three months ended March 31, 2026 and 2025 were $2 million and $4 million, respectively, and were included in the "Operation and maintenance" expense on Edison International's and SCE's condensed consolidated statements of income.

Based upon the CPUC's regulatory treatment of environmental remediation costs incurred at SCE, SCE believes that costs ultimately recorded will not materially affect its results of operations, financial position, or cash flows. There can be no assurance, however, that future developments, including additional information about existing sites or the identification of new sites, will not require material revisions to estimates.

Nuclear Insurance

SCE is a member of Nuclear Electric Insurance Limited ("NEIL"), a mutual insurance company owned by entities with nuclear facilities. NEIL provides insurance for nuclear property damage, including damages caused by acts of terrorism up

Tableof Contents

to specified limits, and for accidental outages for active facilities. The amount of nuclear property damage insurance purchased for San Onofre and Palo Verde exceeds the minimum federal requirement of $50 million and $1.1 billion, respectively. If NEIL losses at any nuclear facility covered by the arrangement were to exceed the accumulated funds for these insurance programs, SCE could be assessed retrospective premium adjustments of up to approximately $15 million per year.

Federal law limits public offsite liability claims for bodily injury and property damage from a nuclear incident to the amount of available financial protection, which is currently approximately $560 million for San Onofre and $16.3 billion for Palo Verde. SCE and other owners of San Onofre and Palo Verde have purchased the maximum private primary insurance available through a Facility Form issued by American Nuclear Insurers. SCE withdrew from participation in the secondary insurance pool for San Onofre for offsite liability insurance effective January 5, 2018. Based on its ownership interests in Palo Verde, SCE could be required to pay a maximum of approximately $79 million per nuclear incident for future incidents. However, it would have to pay no more than approximately $12 million per future incident in any one year. Based on its ownership interests in San Onofre and Palo Verde prior to January 5, 2018, SCE could be required to pay a maximum of approximately $255 million per nuclear incident and a maximum of $38 million per year per incident for liabilities arising from events prior to January 5, 2018, although SCE is not aware of any such events.

Note 13. Equity

Common Stock

Stock Repurchase Programs

The Edison International Board of Directors authorizes stock repurchase programs to repurchase common stock. These programs are intended to offset dilution from common stock issued under Edison International's long-term incentive compensation programs and are funded using Edison International's working capital. The timing and the amount of any repurchases of common stock will be determined by Edison International's management based on their evaluation of market conditions and other factors. Repurchases may be executed through various methods, including open market purchases, privately negotiated transactions, and other transactions in accordance with applicable securities laws. Any repurchased shares of common stock will be retired. The programs do not obligate Edison International to acquire any particular amount of common stock, and may be suspended or discontinued at any time at its discretion.

In December 2025, the Edison International Board of Directors authorized a program that provides for the repurchase of up to $70 million of common stock from February 20, 2026 to March 2, 2027 (the "2026 Share Repurchase Program").

In December 2024, the Edison International Board of Directors authorized a program for repurchase of up to $75 million of its common stock from February 2025 until February 2026 (the "2025 Share Repurchase Program").

During the three months ended March 31, 2026, Edison International repurchased and retired 397,631 shares under the 2025 and 2026 Repurchase Programs. As of March 31, 2026, $60 million of common stock remained for repurchase under the 2026 Repurchase Program.

Preferred Stock

In the first quarter of 2026, Edison International redeemed all remaining shares of its Series A Preferred Stock and repurchased 4,434 shares of its Series B Preferred Stock for $414 million and $4 million, respectively. Edison International recorded a $5 million loss on the repurchase and redemption of the preferred stocks, which was reflected in "Preferred stock dividend requirements of Edison International" on the condensed consolidated statements of income.

Preference Stock of SCE

In March 2026, SCE redeemed all remaining shares of its Series K for $119 million. SCE recorded a $3 million loss on the redemption of the preference stock, and the loss was reflected in "Preference stock dividend requirements" on the condensed consolidated statements of income.

Note 16. Related-Party Transactions

SCE purchased wildfire liability insurance from EIS prior to its customer-funded wildfire self-insurance, which was implemented in July 2023. In addition, one of the EIS wildfire liability insurance policies was amended in February 2025 to reimburse SCE for $50 million in claim costs and related legal expenses for a wildfire occurring during the July 1, 2022 through June 30, 2023 policy period. For further information, see Note 12. The expected insurance recoveries from previously purchased wildfire-related insurance from EIS included in SCE's condensed consolidated balance sheets were $118 million and $226 million at March 31, 2026 and December 31, 2025, respectively.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

MANAGEMENT OVERVIEW

Highlights of Operating Results

Edison International is the ultimate parent holding company of SCE and Edison Energy, LLC, doing business as Trio. SCE is an investor-owned public utility primarily engaged in the business of supplying and delivering electricity to an approximately 50,000 square mile area across Southern, Central and Coastal California. Trio is a global energy advisory firm providing integrated sustainability and energy solutions to commercial, industrial and institutional customers. Trio's business activities are currently not material to report as a separate business segment.

Edison International's earnings are prepared in accordance with GAAP. Management uses core earnings (loss) internally for financial planning and for analysis of performance. Core earnings (loss) 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 (loss) are a non-GAAP financial measure and may not be comparable to those of other companies. Core earnings (loss) are defined as earnings available 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. SCE implemented a customer-funded wildfire self-insurance program in 2023. With the commencement of this program, Edison International and SCE no longer consider wildfire-related claim losses to be representative of ongoing earnings and treat such costs as non-core items.

1SCE and Edison International Parent and Other non-core items are tax-effected at an estimated statutory rate of approximately 28%; wildfire claims and expenses insured by EIS are tax-effected at the federal statutory rate of 21%.

Edison International's first quarter 2026 earnings decreased $905 million from the first quarter of 2025, resulting from a decrease in SCE's earnings of $948 million, partially offset by a decrease in Edison International Parent and Other's loss of $43 million. SCE's lower net income consisted of a $16 million non-core loss in 2026 compared to $947 million non-core earnings in 2025, partially offset by $15 million of higher core earnings. Edison International Parent and Other's loss decreased by $43 million due to $40 million of higher non-core earnings and $3 million of lower core loss.

Tableof Contents

The increase in SCE's core earnings for the three months ended March 31, 2026 from the same period in 2025 was primarily due to the adoption of the 2025 GRC final decision in the third quarter of 2025, partially offset by the absence of a benefit to interest expense related to cost recoveries authorized under the TKM Settlement Agreement in 2025. The decrease in Edison International Parent and Other's core loss for the three months ended March 31, 2026, was primarily due to lower preferred stock dividends, partially offset by higher interest expense.

Consolidated non-core items for the three months ended March 31, 2026 and 2025 for Edison International included:

• Wildfire-related recoveries, net of claims and expenses:
• Net earnings of $13 million ($9 million after-tax) recorded in 2026 primarily due to expected recoveries, partially offset by claims and legal expenses associated with Other Wildfire Events.
• Net earnings of $1,351 million ($973 million after-tax) in 2025 primarily related to the TKM Settlement Agreement and insurance reimbursements related to Other Wildfire Events.

See "Notes to Condensed Consolidated Financial Statements—Note 12. Commitments and Contingencies" for further information.

• Charges of $35 million ($25 million after-tax) and $36 million ($26 million after-tax) recorded in 2026 and 2025, respectively, from amortization of SCE's contributions to the Wildfire Fund. See "Notes to Condensed Consolidated Financial Statements—Note 1. Summary of Significant Accounting Policies" for further information.
• Net earnings of $1 million ($1 million after-tax) recorded in 2026 primarily due to updated estimates of claims accruals, net of legal expenses, and charges of $50 million ($39 million after-tax) recorded in 2025, both related to wildfire claims insured by EIS. See "Notes to Condensed Consolidated Financial Statements— Note 12. Commitments and Contingencies" for further information.

See "Results of Operations" for discussion of SCE's and Edison International Parent and Other's results of operations.

Capital Program

Capital Expenditures

Total capital expenditures (including accruals) were $1.5 billion for the three months ended March 31, 2026 and 2025. As discussed in the 2025 Form 10-K, SCE forecasts total capital expenditures ranging from $37.5 billion to $40.6 billion for 2026 – 2030, and weighted average annual rate base from $50.8 billion to $67.9 billion for 2026 – 2030. These capital program and rate base projections incorporate the planned CPUC-jurisdictional spending as informed by the 2025 GRC final decision and expected FERC capital expenditures, see "Liquidity and Capital Resources—SCE—Capital Investment Plan" below and "Management Overview — Capital Program" in the 2025 MD&A.

Southern California Wildfires

Unprecedented weather conditions in California due to climate change and greater concentrations of residents in high-fire risk areas, among other things, have contributed to wildfires, including those where SCE's equipment has been alleged to be associated with the fire's ignition, that have caused loss of life and substantial damage in SCE's service area.

SCE continues to implement its WMP to reduce the risk of SCE equipment contributing to the ignition of wildfires. Further to the investments SCE is making as part of its WMP, SCE also uses its PSPS program to proactively de-energize power lines as a last resort to mitigate the risk of significant wildfires during extreme weather events. In addition, California has increased its investment in wildfire prevention and fire suppression capabilities. Yet, the potential for catastrophic wildfire activity in SCE's service area still exists.

In February 2026, the OEIS issued a final decision approving SCE’s 2026 – 2028 WMP. In March 2026, the OEIS issued SCE's safety certification which is valid until March 2, 2027. Provided SCE timely submits a request for its next safety certification, its current safety certification will remain valid until the OEIS acts on its request.

In April 2026, the CEA submitted to the California Legislature and the Governor a report required by SB 254 that evaluates California’s approach to natural catastrophe risk, including wildfires. The report identifies increasing natural catastrophe risk driven by climate‑related factors, development in wildfire‑prone areas, fuel conditions, and other systematic factors, and highlights challenges in wildfire mitigation, insurance availability, liability allocation, and post‑event recovery. The report observes that failure to address escalating wildfire risk would prolong recovery for affected communities, significantly increase electric utility costs, driving higher customer rates, and also could elevate insurance premiums statewide. Continued inaction would expose SCE to risk of credit downgrades and heightened financial stress, limiting access to capital needed to maintain safe and reliable infrastructure. Taken together, these dynamics would exacerbate

Tableof Contents

affordability pressures, undermine market stability, and impede SCE's ability to support long‑term reliability and climate‑related objectives.

Against this backdrop, the report presents a framework of policy options organized around three non‑exclusive pathways: committing to community‑level wildfire mitigation, including measures to reduce the severity and scale of catastrophic events through coordinated community‑based risk reduction, home‑ and neighborhood‑level hardening, and risk-informed targeting of mitigation investments; equitably allocating catastrophe burdens among stakeholders, including through insurance and liability‑related mechanisms such as insurance market reforms, quicker compensation and claims‑handling structures, and potential changes to utility wildfire liability frameworks; and defining potential state roles in catastrophe resilience, including options such as expanded or restructured catastrophe financing mechanisms, state‑level risk pooling or backstops, and other approaches intended to address extreme loss events.

The report discusses options with varying implementation timeframes and fiscal impacts and does not recommend or endorse any specific policy approach. Edison International and SCE are engaging with stakeholders in the legislative process related to wildfire-related risks, however, they cannot predict whether or when there will be a comprehensive economy-wide solution mitigating the significant risk faced by California investor-owned utilities related to wildfires.

Eaton Fire

In January 2025, several wind-driven wildfires impacted portions of SCE's service area, causing loss of life, substantial damage to both residential and business properties, and service outages for SCE customers. One of the largest of these wildfires, the Eaton Fire, ignited in SCE's service area in Los Angeles County and spread due to a number of contributing factors under conditions of an extreme Santa Ana windstorm.

The Los Angeles County Fire Department is leading the investigation into the origin and cause of the Eaton Fire, with the assistance of CAL FIRE, and has identified a preliminary area of origin of the fire. SCE has transmission facilities in the preliminary area of origin and the SED is conducting an investigation with respect to the Eaton Fire. Edison International and SCE are also aware of an ongoing investigation by the Los Angeles District Attorney's Office of the Eaton Fire for the purpose of determining whether any criminal violations have occurred. SCE could be subject to material fines, penalties, or restitution if it is determined that it failed to comply with applicable laws and regulations. SCE is not aware of any basis for felony liability with regards to the Eaton Fire. Any fines and penalties incurred in connection with the Eaton Fire will not be recoverable from insurance, from the Wildfire Fund, or through electric rates.

Multiple lawsuits related to the Eaton Fire have been initiated against SCE and Edison International by individual plaintiffs, subrogation plaintiffs, and public entity plaintiffs related to the Eaton Fire. A bellwether jury trial in the Eaton Fire litigation has been set for January 2027.

SCE’s internal review into the facts and circumstances of the Eaton Fire is complex and ongoing. SCE's review includes ongoing inspections of its facilities and records and of third-party information and testing. While SCE has not conclusively determined that its equipment caused the ignition of the Eaton Fire, a viable explanation is that a de-energized idle SCE transmission facility in the preliminary area of origin was associated with the ignition of the fire and 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 and is pursuing settlement of claims through its Wildfire Recovery Compensation Program, a program designed to enable eligible individuals and businesses impacted by the Eaton Fire to seek expedited resolution of their claims.

SCE has entered into settlements with insurance claimants and claimants under its Wildfire Recovery Compensation Program related to the Eaton Fire. As of March 31, 2026, SCE had recorded $1.3 billion in losses related to these settlements. SCE also recorded expected recoveries from customer-funded self-insurance of $917 million, from the Wildfire Fund of $295 million, and through FERC electric rates of $70 million. In total, through March 31, 2026, the net after-tax charge to earnings recorded related to the settlements was $9 million, the after-tax impact of the required $12.5 million shareholder contribution related to SCE's customer-funded self-insurance coverage.

In light of pending litigation, it is probable that Edison International and SCE will incur additional material losses in connection with the Eaton Fire. Given, among other things, the complexities associated with estimating damages, the large number and varying types of claims and the interrelationship among the claims, uncertainties related to the sufficiency of insurance held by plaintiffs and potential plaintiffs, and uncertainties related to litigation processes and the Wildfire Recovery Compensation Program, Edison International and SCE are currently unable to reasonably estimate a range of losses that may be incurred in connection with the Eaton Fire.

In January 2026, SCE filed a cross-complaint against certain public and private entities whose actions or inaction may have caused, contributed to or exacerbated the losses that resulted from the fire.

Tableof Contents

SCE exhausted self-insurance recoveries available for losses related to the Eaton Fire as a result of costs incurred and settlements entered into as of February 11, 2026. SCE has advised the administrator of the Wildfire Fund that it anticipates that it will seek reimbursement of eligible claims arising from the Eaton Fire from the Initial Account and the administrator has confirmed that the Eaton Fire is a "covered wildfire" for purposes of accessing the Initial Account. SCE will be reimbursed for losses incurred in excess of $1.0 billion for eligible claims for third-party damages related to the Eaton Fire from the Initial Account, subject to approval of the fund administrator and the Initial Account's claims-paying capacity. The fund administrator has reported that the fund's claims-paying capacity for the Eaton Fire, as of September 30, 2025, exceeds $21 billion.

SCE will file an application with the CPUC for review of its costs and expenses related to the Eaton Fire after it has resolved all or, if authorized by the CPUC, substantially all third-party damage claims related to the fire, or upon earlier request of the fund administrator. Because SCE held a valid safety certification at the time of the Eaton Fire, SCE will be presumed to have acted prudently unless a party in the proceeding creates "serious doubt" as to the reasonableness of its conduct, in which case SCE will have the burden of dispelling that doubt and proving its conduct was prudent. The prudency standard does not necessitate perfect conduct and California Wildfire Legislation requires that the CPUC allow recovery if it determines that SCE's conduct related to the ignition of the Eaton Fire was consistent with actions of a reasonable utility. SCE believes that the CPUC's determination regarding the reasonableness of its ignition-related conduct should be based on an evaluation of the reasonableness of its overall policies, systems, and practices. The CPUC has not yet issued a decision applying the California Wildfire Legislation prudency framework to a wildfire cost-recovery proceeding.

SCE believes that it is a reasonable operator of its electric system. 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.

The CPUC will determine the prudency of SCE's ignition-related conduct in a formal proceeding. If the CPUC finds that SCE's conduct related to the ignition of the Eaton Fire was not prudent, it may nevertheless allow cost recovery in full or in part taking into account factors both within and beyond SCE's control that may have exacerbated the costs, including, for example, winds, humidity, temperature, emergency response, evacuation timing and availability of firefighting resources. Because SCE held a safety certification at the time of the ignition, it will be required to reimburse the Initial Account only for amounts disallowed by the CPUC up to the applicable Liability Cap of approximately $4.3 billion, unless the fund administrator finds that SCE's actions or inactions relative to the ignition of the Eaton Fire constitute conscious or willful disregard of the rights and safety of others, in which case SCE will be required to reimburse the Initial Account for all withdrawn amounts that the CPUC disallowed.

SCE will be able to seek recovery of prudently incurred uninsured wildfire costs not covered by the Initial Account, assessed under the prudency standard clarified under the California Wildfire Legislation, through electric rates.

RESULTS OF OPERATIONS

SCE

The following discusses SCE's condensed consolidated statements of income for the three months ended March 31, 2026 and 2025. In general, expenses SCE is authorized to pass through directly to customers (such as purchased power and fuel expenses, flow-through taxes, as well as costs incurred for various programs and activities, such as public purpose programs and vegetation management activities) and the corresponding amount of revenues collected to recover those pass-through costs do not impact net income.

The following tables summarize SCE's results of operations for the periods indicated.

Three months ended March 31, 2026 versus March 31, 2025

Operating Revenue

An increase in operating revenue of $294 million was primarily due to:

• An increase in revenue of $282 million driven by the 2025 GRC final decision, including the 2026 escalation mechanism set forth in the 2025 GRC decision. SCE's results of operations for the three months ended March 31, 2025 were based on the 2024 authorized revenue. SCE received the final 2025 GRC decision in the third quarter of 2025 and the authorized revenue attributable to first quarter of 2025 but recorded subsequently in 2025 was approximately $202 million.
• An increase in revenue of $15 million related to net higher expenses that are passed through to customers, which mainly included increases in:
• Interest expense of $29 million;
• Depreciation and amortization expense of $25 million;
• Operation and maintenance expense of $16 million;
• Income tax expense of $14 million;
• Wildfire-related claims, net of recoveries of $8 million;
• Property and other taxes of $4 million;

Tableof Contents

partially offset by decreases in:

• Purchased power and fuel expense of $77 million;
• Other income of $4 million.

Purchased Power and Fuel

A decrease in purchased power and fuel costs of $77 million was primarily due to lower energy prices, partially offset by higher capacity costs (offset in "Operating Revenue" above).

Operation and Maintenance

An increase in operation and maintenance expense of $36 million was primarily due to:

• An increase of $18 million mainly related to higher inspections and preventative maintenance activities in 2026.
• A net increase of $16 million pass-through costs (offset in "Operating Revenue" above), which is mainly related to higher public programs expenses and higher previously deferred costs authorized for recovery in 2026, partially offset by lower uncollectible expense.

Wildfire-related Claims, Net of Recoveries

A decrease in recoveries of wildfire-related claims of $1,352 million was primarily due to

• $1,341 million claim costs recovery authorized and recorded in 2025 under the TKM Settlement Agreement;
• $14 million insurance reimbursements recorded in 2025 related to Other Wildfire Events;
• $8 million of net recognition of previously deferred claim costs expected to be recovered through FERC rates (offset in "Operating Revenue" above);

partially offset by:

• Benefits of $11 million mainly due to expected recoveries related to Other Wildfire Events.

For further information, see "Notes to Condensed Consolidated Financial Statements—Note 12. Commitments and Contingencies—Contingencies—Southern California Wildfires and Mudslides."

Depreciation and Amortization

An increase in depreciation and amortization expense of $92 million was primarily due to higher plant balances, $25 million of which were pass-through costs mainly associated with securitization debt (offset in "Operating Revenue" above).

Property and Other Taxes

An increase in property and other taxes of $13 million was primarily related to higher assessed property values and $4 million of higher pass-through costs (offset in "Operating Revenue" above).

Interest Expense

An increase in interest expense of $210 million was primarily due to:

• $171 million cost recovery authorized and recorded in 2025 under the TKM Settlement Agreement.
• $29 million pass-through expense mainly associated with increased securitization debt (offset in "Operating Revenue" above);
• $10 million higher interest expense from an increase in borrowings.

Other Income, Net

An increase in other income of $10 million was primarily due to an increase in equity allowance for funds used during construction and $4 million of higher pass-through costs (offset in "Operating Revenue" above).

Income Taxes

A decrease in income tax expense of $360 million was primarily due to $370 million of lower tax expense on lower pre-tax income, partially offset by $10 million of lower flow-through tax benefits that were passed through to customers (offset the

Tableof Contents

corresponding pre-tax amount in "Operating Revenue"). See "Notes to Condensed Consolidated Financial Statements—Note 8. Income Taxes" for a reconciliation of the federal statutory rate to the effective income tax rate.

Edison International Parent and Other

Results of operations for Edison International Parent and Other include amounts from other subsidiaries that are not reportable segments, as well as intercompany eliminations.

Loss from Operations

The following table summarizes the results of Edison International Parent and Other:

The net loss available to common shareholders from operations of Edison International Parent and Other decreased $43 million for the three months ended March 31, 2026, compared to the same period in 2025, primarily due to lower expenses from wildfire claims insured by an EIS insurance contract (see "Notes to Condensed Consolidated Financial Statements—Note 12. Commitments and Contingencies and Note 16. Related-Party Transactions" for further information), and lower preferred stock dividends, partially offset by higher interest expense.

LIQUIDITY AND CAPITAL RESOURCES

SCE

SCE's ability to operate its business, fund capital expenditures, and implement its business strategy is dependent upon its operating cash flow and access to the bank and capital markets. SCE's overall cash flows fluctuate based on, among other things, its ability to recover its costs in a timely manner from its customers through regulated rates, changes in commodity prices and volumes, collateral requirements, interest obligations, dividend payments to and equity contributions from Edison International, obligations to preference shareholders, and the outcome of tax, regulatory and legal matters.

In the next 12 months, SCE expects to fund its cash requirements through operating cash flows, capital market and bank financings, and equity contributions from Edison International Parent, as needed. In addition, SCE expects to fund authorized wildfire-related cost recoveries through securitization financings, and fund costs related to the Eaton Fire through customer-funded self-insurance and reimbursement from the Initial Account of the Wildfire Fund. SCE also has availability under its credit facility and agreements with lenders to issue bilateral unsecured standby letters of credit to fund cash requirements. SCE may issue additional debt for general corporate purposes.

SCE expects to finance approximately $2.0 billion of cost recoveries authorized under the Woolsey Settlement Agreement through the issuance of securitized recovery bonds, subject to the approval of a securitization financing application filed with the CPUC in January 2026. In April 2026, a proposed decision was issued approving the application and a final decision by the CPUC is expected in May 2026. For further details on the financing order, see "—Regulatory Proceedings—Financing Order." For further details on the settlements, see "Management Overview—Southern California Wildfires and Mudslides" in the 2025 Form 10-K.

During the three months ended March 31, 2026, SCE issued a total of $1.2 billion of first and refunding mortgage bonds. In February 2026, SCE entered into a term loan agreement to borrow $1.5 billion due in March 2027, which was partially used to repay all borrowings under a February 2026 $300 million unsecured term loan agreement. For further details, see "Notes to Condensed Consolidated Financial Statements—Note 5. Debt and Credit Agreements."

In March 2026, SCE fully redeemed 5.45% Fixed-to-Floating Rate Trust Preference Securities issued by SCE Trust V for an aggregate amount paid of $119 million. SCE subsequently exchanged all of these securities for SCE's Series K preference stock, which it retired. For further details, see "Notes to Condensed Consolidated Financial Statements—Note 13. Equity."

For restrictions on SCE's ability to pay dividends, see "Notes to Consolidated Financial Statements—Note 1. Summary of Significant Accounting Policies—SCE Dividends" in the 2025 Form 10-K.

Credit Ratings

SCE's credit ratings may be affected by various factors, including failure by regulators to successfully implement the California Wildfire Legislation in a timely, consistent and credit-supportive manner, or investigations into wildfire events or associated settlements result in material utility liability exposure. In April 2026, the CEA submitted to the California Legislature and the Governor a report required under SB 254. The report observes that continued inaction to address escalating wildfire risk would expose utilities to risk of credit downgrades and heightened financial stress, limiting access to capital needed to maintain safe and reliable infrastructure. SCE cannot predict whether or when there will be a comprehensive economy-wide solution mitigating the significant risk faced by California investor-owned utilities related to wildfires. For further discussion about the report see "— Management Overview—Southern California Wildfires."

Additionally, a persistent increase in the frequency and severity of wildfires in California may lead the credit rating agencies to reassess SCE's wildfire-related operational risk exposure or believe the Wildfire Fund is at risk of material depletion. Credit rating downgrades increase the cost and may impact the availability of short-term and long-term borrowings, including commercial paper, credit facilities, bond financings or other borrowings. In addition, some of SCE's power procurement contracts, environmental remediation obligations and workers' compensation self-insurance would require SCE to pay related liabilities or post additional collateral if SCE's credit rating were to fall below investment grade. For further details, see "—Margin and Collateral Deposits."

Available Liquidity

At March 31, 2026, SCE had cash on hand of $110 million and restricted cash of $517 million collected from customer-funded self-insurance. SCE also has approximately $3.3 billion available to borrow on its $3.4 billion revolving credit facility. The credit facility is available for borrowing needs until May 2029. The aggregate maximum principal amount under the SCE revolving credit facility may be increased up to $4.0 billion, provided that additional lender commitments are obtained. SCE also had standby letters of credit with total capacity of $660 million, and the unused amount was

Tableof Contents

$560 million as of March 31, 2026. For further details, see "Notes to Condensed Consolidated Financial Statements—Note 5. Debt and Credit Agreements."

SCE may finance balancing account undercollections and working capital requirements to support operations and capital expenditures with commercial paper, its credit facilities or other borrowings, subject to availability in the bank and capital markets and within levels authorized by the CPUC. As necessary, SCE will utilize its available liquidity, capital market financings, other borrowings or parent company equity contributions to SCE in order to meet its obligations as they become due, including costs related to the wildfire events. SCE expects to use customer-funded self-insurance and reimbursement from the Initial Account to fund wildfire claims. For further information, see "Management Overview—Southern California Wildfires."

Debt Covenant

SCE's credit facilities and term loan require a debt to total capitalization ratio as defined in the applicable agreements of less than or equal to 0.65 to 1. At March 31, 2026, SCE's debt to total capitalization ratio was 0.57 to 1.

At March 31, 2026, SCE was in compliance with all financial covenants that affect access to capital.

Regulatory Proceedings

2024 Multi-year Wildfire Mitigation and Catastrophic Events Filing ("2024 WMCE Filing")

In December 2025, SCE filed its 2024 WMCE Filing, seeking to recover incremental operating and maintenance expenses of $55 million and incremental capital expenditures of $78 million, recorded in the wildfire risk mitigation balancing account, as well as incremental storm-related costs associated with certain 2017 – 2021 events recorded in the catastrophic event memorandum account. The application also seeks recovery of $36 million in wildfire mitigation related capital expenditures incurred in 2022 that were previously denied without prejudice and permitted to be included in base rates as part of the post-test year ratemaking mechanism. In April 2026, the CPUC adopted a schedule with a proposed decision expected in the first quarter of 2027.

NextGen Enterprise Resource Planning ("ERP") Program

In March 2025, SCE filed an application with the CPUC seeking authorization to recover costs related to its NextGen ERP Program. In April 2026, the CPUC issued a procedural ruling requesting additional information from SCE, which SCE timely provided. SCE anticipates that a proposed decision will be issued by the CPUC in 2026. While this ruling may extend the schedule for a final CPUC decision within 2026, it does not alter the scope of the application. Any delay could affect the timing of cost recovery and increase implementation‑related uncertainty.

Financing Order

In January 2026, SCE filed an application with the CPUC seeking an irrevocable order to finance approximately $2.0 billion of costs and expenses related to the Woolsey Fire and associated financing costs through the issuance of securitized bonds. These amounts were approved for recovery in the Woolsey Settlement Agreement. In April 2026, the CPUC issued a proposed decision approving the requested financing order. For further details on the settlements, see "Management Overview—Southern California Wildfires and Mudslides" in the 2025 Form 10-K.

Advanced Metering Infrastructure ("AMI") 2.0 Program

In March 2026, SCE filed an application with the CPUC requesting approval of the AMI 2.0 program, which is intended to replace SCE's existing metering infrastructure, including meters, network communications, software systems, and data analytics, as well as to enable new customer programs. The application seeks authorization for forecasted capital expenditures of $3.1 billion and operations and maintenance costs of $366 million to be incurred between 2026 and 2033, as well as authorization to establish an AMI 2.0 Memorandum Account and an AMI 2.0 Balancing Account to record the associated costs.

Capital Investment Plan

Alberhill System Project

In March 2026, the CPUC approved the Certificate of Public Convenience and Necessity for the project, authorizing the construction to proceed. Construction for the project is expected to begin in the third quarter of 2026. For further details on the project, see "Liquidity and Capital Resources — Southern California Edison Company — Capital Investment Plan" in 2025 Form 10-K.

Margin and Collateral Deposits

Certain derivative instruments, power and energy procurement contracts, and other contractual arrangements contain collateral requirements. Future collateral requirements may differ from the requirements at March 31, 2026, due to the addition of incremental power and energy procurement contracts with collateral requirements, if any, the impact of changes in wholesale power and natural gas prices on SCE's contractual obligations, and the impact of SCE's credit ratings falling below investment grade. See "—SCE" above for further information on SCE's credit ratings.

The table below provides the amount of collateral posted by SCE to its counterparties as well as the potential collateral that would have been required as of March 31, 2026, if SCE's credit rating had been downgraded to below investment grade as of that date. The table below also provides the potential collateral that could be required due to adverse changes in wholesale power and natural gas prices over the remaining lives of existing power and fuel contracts.

In addition to amounts shown in the table, power and fuel contract counterparties may also institute new collateral requirements, applicable to future transactions to allow SCE to continue trading in power and fuel contracts at the time of a downgrade or upon significant increases in market prices.

1Net collateral provided to counterparties and other brokers consisted of $108 million in letters of credit and surety bonds and $52 million of cash collateral.

2Represents potential collateral requirements for accounts payable and mark-to-market valuation at March 31, 2026. Requirement varies throughout the period and is generally lower at the end of the month.

3Incremental collateral requirements were based on potential changes in SCE's forward positions as of March 31, 2026, due to adverse market price movements over the remaining lives of the existing power and fuel derivative contracts using a 95% confidence level.

Furthermore, SCE may be required to post collateral for workers' compensation in excess of standard formula amounts, currently up to $115 million, in the event of volatile credit rating conditions, during which the Office of Self-Insurance Plans, which oversees workers' compensation self-insurance within California, may exercise discretion to impose higher collateral requirements. As of March 31, 2026, SCE had $12 million of collateral posted under such discretionary authority. SCE may also be required to post up to $50 million in collateral in connection with its environmental remediation obligations, within 120 days of the end of the fiscal year in which a downgrade below investment grade occurs.

Edison International Parent and Other

In the next 12 months, Edison International Parent expects to fund its net cash requirements through cash on hand, dividends from SCE, and capital market and bank financings. Edison International Parent may finance its ongoing cash requirements, including dividends, working capital requirements, payment of obligations, and capital investments, including capital contributions to subsidiaries, with short-term or other financings, subject to availability in the bank and capital markets.

At March 31, 2026, Edison International Parent and Other had cash on hand of $58 million and $0.9 billion available to borrow on its $1.5 billion revolving credit facility. The credit facility is available for borrowing needs until May 2029. The aggregate maximum principal amount under the Edison International Parent revolving credit facility may be increased up to $2.0 billion, provided that additional lender commitments are obtained. For further details, see "Notes to Condensed Consolidated Financial Statements—Note 5. Debt and Credit Agreements."

In the first quarter of 2026, Edison International Parent issued $550 million of 4.80% senior notes due in 2031. For further details, see "Notes to Condensed Consolidated Financial Statements—Note 5. Debt and Credit Agreements."

In the first quarter of 2026, Edison International redeemed all remaining shares of its 5.375% Fixed-Rate Reset Cumulative Perpetual Preferred Stock, Series A ("Series A Preferred Stock") and repurchased 4,434 shares of 5.00% Fixed-Rate Reset Cumulative Perpetual Preferred Stock, Series B ("Series B Preferred Stock") for $414 million and $4 million, respectively. For further details, see "Notes to Condensed Consolidated Financial Statements—Note 13. Equity."

Edison International Parent and Other's liquidity and its ability to pay operating expenses and pay dividends to preferred and common shareholders are dependent on access to the bank and capital markets, dividends from SCE, realization of tax benefits and its ability to meet California law requirements for the declaration of dividends. For information on the California law requirements on the declaration of dividends, see "Notes to Consolidated Financial Statements—Note 1. Summary of Significant Accounting Policies—SCE Dividends" in the 2025 Form 10-K. Edison International intends to maintain its target payout ratio of 45% – 55% of SCE's core earnings, subject to the factors identified above.

Edison International's ability to declare and pay common dividends may be restricted under the terms of its Series A and Series B Preferred Stock. For further information, see "Notes to Consolidated Financial Statements—Note 14. Equity" in the 2025 Form 10-K.

Edison International Parent's credit facility and term loan require a consolidated debt to total capitalization ratio as defined in the applicable agreements of less than or equal to 0.70 to 1. At March 31, 2026, Edison International's consolidated debt to total capitalization ratio was 0.65 to 1.

At March 31, 2026, Edison International Parent was in compliance with all financial covenants that affect access to capital.

Credit Ratings

Edison International Parent's credit ratings may be affected by various factors, including failure by regulators to successfully implement the California Wildfire Legislation in a timely, consistent and credit-supportive manner, or investigations into wildfire events or associated settlements result in material utility liability exposure. In April 2026, the CEA submitted to the California Legislature and the Governor a report required under SB 254.

Additionally, a persistent increase in the frequency and severity of wildfires in California may lead the credit rating agencies to reassess Edison International Parent's wildfire-related operational risk exposure or believe the Wildfire Fund is at risk of material depletion. Credit rating downgrades increase the cost and may impact the availability of short-term and long-term borrowings, including commercial paper, credit facilities, note financings or other borrowings.

Edison International Income Taxes

Inflation Reduction Act of 2022

The IRA imposed a corporate alternative minimum tax ("CAMT"), which Edison International and SCE are subject to beginning in 2026. Edison International and SCE expect that any CAMT paid will be creditable against future income taxes.

Tableof Contents

In addition, under the IRA, SCE expects to generate $158 million investment tax credit in future periods related to utility owned storage projects. The associated tax benefits will be recognized and returned to customers as the credits are utilized.

Historical Cash Flows

SCE

Net Cash Provided by Operating Activities

The following table summarizes major categories of net cash provided by operating activities as provided in more detail in SCE's condensed consolidated statements of cash flows for the three months ended March 31, 2026 and 2025.

1Includes nuclear decommissioning trusts. See "Nuclear Decommissioning Activities" below for further information.

Net cash provided by operating activities increased by $248 million in the first quarter of 2026 compared to the same period of 2025. The change was primarily due to the increase in 2026 escalation mechanism for rates set forth in the 2025 GRC final decision and the decrease in wildfire-related claim payments, partially offset by a decrease from changes in working capital.

The net (outflows) inflows in cash resulting from working capital was $(49) million and $44 million during the three months ended March 31, 2026 and 2025, respectively. Net cash outflows in 2026 were primarily due to payments of operating expenses, partially offset by inflows from net decreases in customer receivables and unbilled revenue. Net cash inflows in 2025 were primarily due to cash collected from the sale of renewable energy credits under a CPUC-established program.

Net cash provided by (used in) regulatory assets and liabilities, including changes in net over or undercollections recorded in balancing accounts, was $81 million and $(1.4) billion during the three months ended March 31, 2026 and 2025, respectively. Net increase in regulatory assets and liabilities of $1.5 billion is primarily due to cost recoveries authorized under the TKM Settlement Agreement in 2025, which is mostly offset with the decrease in net income after adjustment for non-cash items.

Tableof Contents

Net Cash Provided by Financing Activities

The following table summarizes cash provided by financing activities for the three months ended March 31, 2026 and 2025, respectively. Issuances of debt are discussed in "Notes to Condensed Consolidated Financial Statements—Note 5. Debt and Credit Agreements."

Net Cash Used in Investing Activities

Cash flows used in investing activities are primarily due to total capital expenditures of $1.5 billion and $1.4 billion for three months ended March 31, 2026 and 2025, respectively. In addition, SCE had a net (purchase) redemption of nuclear decommissioning trust investments of $(2) million and $34 million during the three months ended March 31, 2026 and 2025, respectively. See "Nuclear Decommissioning Activities" below for further discussion.

Nuclear Decommissioning Activities

SCE's condensed consolidated statements of cash flows include nuclear decommissioning activities, which are reflected in the following line items:

Net cash provided by (used in) operating activities relates to interest and dividends less administrative expenses, taxes and SCE's decommissioning costs. Investing activities represent the purchase and sale of investments within the nuclear decommissioning trusts, including the reinvestment of earnings from nuclear decommissioning trust investments. The net cash impact reflects timing of decommissioning payments ($20 million and $61 million in 2026 and 2025, respectively) and reimbursements to SCE from the nuclear decommissioning trust ($27 million and $59 million in 2026 and 2025, respectively).

Tableof Contents

Edison International Parent and Other

The table below sets forth condensed historical cash flow from operations for Edison International Parent and Other, including intercompany eliminations.

Net Cash Used in Operating Activities

Net cash used in operating activities increased by $45 million in 2026 compared to 2025. This was primarily due to a $77 million cash inflow in 2025 from an intercompany tax settlement with SCE, offset by $32 million lower operating expense.

Net Cash Provided by Financing Activities

Net cash provided by financing activities was as follows:

Contingencies

Edison International's and SCE's material contingencies are discussed in "Notes to Condensed Consolidated Financial Statements—Note 12. Commitments and Contingencies—Contingencies."

MARKET RISK EXPOSURES

Edison International's and SCE's primary market risks are described in the 2025 Form 10-K, and there have been no material changes during the three months ended March 31, 2026.

CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

The management of Edison International and SCE, under the supervision and with the participation of Edison International's and SCE's respective Chief Executive Officers and Chief Financial Officers, have evaluated the effectiveness of Edison International's and SCE's disclosure controls and procedures (as that term is defined in Rules 13a-15(e) or 15d-15(e) under the Securities Exchange Act of 1934, as amended), respectively, as of the end of the first quarter of 2026. Based on that evaluation, Edison International's and SCE's respective Chief Executive Officers and Chief Financial Officers have each concluded that, as of the end of the period, Edison International's and SCE's disclosure controls and procedures, respectively, were effective.

Changes in Internal Control Over Financial Reporting

There were no changes in Edison International's or SCE's internal control over financial reporting, respectively, during the first quarter of 2026 that have materially affected, or are reasonably likely to materially affect, Edison International's or SCE's internal control over financial reporting.

Jointly Owned Utility Plant

Edison International's and SCE's respective scope of evaluation of internal control over financial reporting includes their Jointly Owned Utility Projects as discussed in "Notes to Consolidated Financial Statements—Note 2. Property, Plant and Equipment" in the 2025 Form 10-K.

Item 1. LEGAL PROCEEDINGS

LEGAL PROCEEDINGS

2017/2018 Wildfire/Mudslide Events

The lawsuits related to the 2017/2018 Wildfire/Mudslide Events naming SCE as a defendant have been filed by three categories of plaintiffs: individual plaintiffs, subrogation plaintiffs and public entity plaintiffs. A number of the lawsuits also name Edison International as a defendant and some of the lawsuits were filed as purported class actions. As of April 21, 2026, in addition to the outstanding claims of approximately 70 claims of approximately 15,000 initial individual plaintiffs, there were alleged and potential claims of certain public entity plaintiffs, including CAL OES, outstanding. SCE has settled all fire suppression and subrogation plaintiffs' claims related to the 2017/2018 Wildfire/Mudslide Events, except for one indemnification claim. The litigation could take a number of years to be completely resolved because of the complexity of the matters and number of plaintiffs. The statutes of limitations for individual plaintiffs in the 2017/2018 Wildfire/Mudslide Events have expired.

As of April 21, 2026, SCE was aware of 10 pending unsettled lawsuits representing 22 individual plaintiffs related to the Thomas and Koenigstein Fires and the Montecito Mudslides naming SCE as a defendant. 4 of the 10 lawsuits also name Edison International as a defendant based on its ownership and alleged control of SCE. One of the lawsuits was filed as a purported class action. The court has denied class certification in the one lawsuit that was filed as a purported class action and plaintiffs have appealed the denial. The lawsuits, which have been filed in the superior courts of Ventura, Santa Barbara and Los Angeles Counties allege, among other things, negligence, inverse condemnation, trespass, private nuisance, and violations of the public utilities and health and safety codes. SCE and certain of the individual plaintiffs in the Thomas and Koenigstein Fire litigation have been pursuing settlements of claims under a mediation program adopted to promote an efficient and orderly settlement process. As of April 21, 2026, seven opt-in plaintiff households’ damages-only trials are scheduled in 2026 and 2027.

Eaton Fire

In January 2025, several wind-driven wildfires impacted portions of SCE's service area, causing loss of life, substantial damage and service outages for SCE customers. One of the largest of these wildfires, the Eaton Fire, ignited in SCE's service area in Los Angeles County and spread due to a number of contributing factors under conditions of an extreme Santa Ana windstorm.

Multiple lawsuits related to the Eaton Fire have been initiated against SCE. A number of the lawsuits also name Edison International as a defendant and some of the lawsuits were filed as purported class actions. As of April 21, 2026, SCE was aware of approximately 2,000 currently pending unsettled lawsuits related to the Eaton Fire: representing lawsuits by approximately 30,000 individual plaintiffs, lawsuits by subrogation plaintiffs and lawsuits by public entity plaintiffs, including the United States of America, the County of Los Angeles, the City of Pasadena and the City of Sierra Madre, related to the Eaton Fire. A bellwether jury trial in the Eaton Fire litigation has been set for January 2027. In January 2026, SCE filed a cross-complaint against certain public and private entities whose actions or inaction may have caused, contributed to or exacerbated the losses that resulted from the fire. Several of the cross-complaint defendants have filed motions challenging SCE’s cross-complaint. The hearings on these motions are set for May and June 2026.
