Organization and Basis of Presentation
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.
Consolidation
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.

Segment Information
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.
Allowance for Uncollectible Accounts
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.
Wildfire Fund
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
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
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:
Three months ended March 31,

Basic earnings per share:
Net income available to Edison International common shareholders$531 $1,436 
Earnings allocated to participating securities— (1)
Income available to common shareholders$531 $1,435 
Weighted average common shares outstanding385 385 
Basic earnings per share$1.38 $3.73 
Diluted earnings per share:
Income available to common shareholders$531 $1,435 
Add back: Earnings allocated to participating securities— 1 
Net income available to Edison International common shareholders$531 $1,436 
Weighted average common shares outstanding385 385 
Effect of dilutive securities2 1 
Adjusted weighted average shares – diluted387 386 
Diluted earnings per share$1.37 $3.72 
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
outstanding, but were not included in the computation of diluted earnings per share because the effect would have been antidilutive.
Revenue Recognition
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
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.
