---	---
●	risk that AB 1054 does not effectively mitigate the significant exposure faced by California investor-owned utilities related to liability for damages arising from catastrophic wildfires where utility facilities are alleged to be a substantial cause, including the longevity of the Wildfire Insurance Fund and the CPUC's interpretation of and actions under AB 1054, including its interpretation of the prudency standard clarified by AB 1054;
---	---
●	ability of Edison International and SCE to effectively attract, manage, develop and retain a skilled workforce, including its contract workers;
---	---
●	decisions and other actions by the CPUC, OEIS, the FERC, the NRC and other governmental authorities, including decisions and actions related to nationwide or statewide crisis, determinations of authorized rates of return or return on equity, issuance of SCE's wildfire safety certification, wildfire mitigation efforts, approval and implementation of electrification programs, and delays in executive, regulatory and legislative actions;

---	---
●	pandemics, such as COVID-19, and other events that cause regional, statewide, national or global disruption, which could impact, among other things, Edison International's and SCE's business, operations, cash flows, liquidity and/or financial results and cause Edison International and SCE to incur unanticipated costs;
---	---
●	physical security of Edison International's and SCE's critical assets and personnel and the cybersecurity of Edison International's and SCE's critical information technology systems for grid control, and business, employee and customer data;

Table of Contents 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. 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 of southern California. Edison Energy is a global energy advisory firm providing integrated sustainability and energy solutions to commercial, industrial and institutional customers. Edison Energy'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 attributable to Edison International shareholders less non-core items. Non-core items include income or loss from discontinued operations and income or loss from significant discrete items that management does not consider representative of ongoing earnings, such as write downs, asset impairments 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.

The earnings impacts of wildfires with losses over $1.0 billion are treated as non-core items during the three and nine months ended September 30, 2023 and 2022. Under the new customer-funded self-insurance program, for wildfires ignited from July 1, 2023 through at least December 31, 2024, SCE will have insurance recoveries to offset up to $987.5 million of claims-related losses per policy year, with a maximum potential shareholder contribution of $12.5 million per policy year. Therefore, SCE expects that it will not have material earnings impacts from claims-related losses for wildfires ignited after July 1, 2023, other than if SCE incurs over $1.0 billion of losses in a year and is unable to recover such losses through the Wildfire Insurance Fund. As a result, in the third quarter of 2023, management concluded that the earnings impacts of wildfire claims-related losses will be treated as non-core items prospectively to make core earnings representative of ongoing earnings. For additional information on the customer-funded self-insurance program, see "—Customer-Funded Self-Insurance." 4

1	In the three months ended September 30, 2022, there were no charges included in core earnings, related to claims from wildfires ignited prior to July 1, 2023. In the nine months ended September 30, 2023 and 2022, core earnings included charges of $4 million and $8 million, respectively, related to claims from wildfires ignited prior to July 1, 2023. Core earnings (loss) in periods before the third quarter of 2023 have not been recast to exclude these charges.
---	---
2	SCE and Edison International Parent and Other non-core items are tax-effected at an estimated statutory rate of approximately 28%; customer revenues for EIS insurance contract are tax-effected at an estimated statutory rate of approximately 20%.
---	---

Edison International's third quarter 2023 earnings increased $283 million from the third quarter of 2022, resulting from an increase in SCE's earnings of $319 million and an increase in Edison International Parent and Other's losses of $36 million. SCE's higher net income consisted of $329 million of lower non-core losses and $10 million of lower core earnings. Edison International Parent and Other's increased loss was due to $13 million of lower earnings in non-core items and $23 million of higher core loss. Edison International's earnings for the nine months ended September 30, 2023 increased $622 million from the same period in 2022, resulting from an increase in SCE's earnings of $660 million and an increase in Edison International Parent and Other's loss of $38 million. SCE's higher net income consisted of $593 million of lower non-core losses and $67 million of higher core earnings. Edison International Parent and Other's higher loss consisted of $22 million of higher earnings in non-core items and $60 million of higher core loss.

The decrease in SCE's core earnings for the three months ended September 30, 2023 from the same period in 2022 was primarily due to higher interest expense and lower return on rate base related to the 2022 CSRP decision, partially offset by higher revenue from the escalation mechanism set forth in the 2021 GRC final decision. The increase in SCE's core earnings for the nine months ended September 30, 2023 from the same period in 2022 was primarily due to higher revenue from the 5

Table of Contents escalation mechanism set forth in the 2021 GRC final decision and higher interest income on balancing account undercollections, partially offset by higher interest expense.

The increase in Edison International Parent and Other's core loss for the three and nine months ended September 30, 2023 was primarily due to higher interest expense.

Consolidated non-core items for the nine months ended September 30, 2023 and 2022 primarily included:

Table of Contents 2025 General Rate Case

SCE filed its 2025 GRC application with the CPUC in May 2023, for the four-year period of 2025 – 2028. In its application, SCE is requesting that the CPUC authorize SCE's test year 2025 revenue requirement of approximately $10.3 billion. This represents a $1.9 billion, or 23% increase over the approximately $8.4 billion 2024 revenue requirements requested in Track 4 adjusted for the CPUC's decisions to adopt SCE's 2023 to 2025 cost of capital and expanded customer-funded self-insurance for wildfire-related claims.

SCE's 2025 GRC request also includes proposed revenue requirement increases of approximately $600 million, $700 million and $700 million in 2026, 2027 and 2028, respectively.

SCE's 2025 GRC highlights its focus on safely providing electric service to its customers that is reliable, resilient, and ready for their needs today and the clean energy transition directed by California policy. The critical drivers of SCE's 2025 GRC request include returning to historical levels of infrastructure replacement work necessary for system reliability as wildfire mitigation investments stabilize, investments in reliability and capacity upgrades to ready the grid for increased electrification to meet customer needs and California's electrification and de-carbonization goals, and investments in programs aimed at protecting the safety of the public, customers and SCE's workforce.

For details of 2023 – 2028 capital program forecast and range case, see "—Capital Program."

Track 4

In September 2023, SCE filed an all-party settlement in Track 4. If approved by the CPUC, it will authorize an $8.4 billion revenue requirement for 2024, an approximately $200 million reduction to SCE's initial request. The approved revenue requirement will be subject to adjustments for SCE's 2024 cost of capital and expanded customer-funded self-insurance for wildfire-related claims.

Capital Program

Total capital expenditures (including accruals) were $3.9 billion and $4.1 billion for the first nine months ended September 30, 2023 and 2022, respectively.

SCE forecasts a $43.3 billion total capital program for 2023 through 2028, which includes GRC capital expenditures, CPUC non-GRC capital expenditures, and FERC capital expenditures. If all capital expenditures requested in SCE’s 2025 GRC were approved by the CPUC, SCE forecasts total weighted-average rate base incorporating CPUC- and FERC-jurisdictional capital expenditures increasing to $60.9 billion by 2028. During the quarter ended September 30, 2023, SCE updated the 2023 and 2024 capital expenditures to reflect the significant risk associated with the utility owned storage projects being completed in 2023. In addition, SCE updated 2024 – 2028 capital expenditures to reflect an updated forecast for ongoing delays in the Riverside Transmission Reliability Project (see "Liquidity and Capital Resources—SCE—Capital Investment Plan" in the 2022 MD&A) as well as the Track 4 settlement. SCE also updated the rate base forecast to reflect these factors and a reduction of working capital following implementation of the customer-funded self-insurance program. In October 2023, the CPUC issued a proposed decision that would deny SCE's Building Electrification Program Application. If adopted, the decision would reduce requested capital expenditures by approximately $270 million between 2025 and 2028 (see "Liquidity and Capital Resources—SCE—Regulatory Proceedings" in the 2022 MD&A).

Based on management judgment of potential capital spending variability informed by historical precedent of previously authorized amounts, potential permitting delays and other operational considerations, a range case has been prepared reflecting reductions to GRC capital expenditures, CPUC non-GRC capital expenditures and FERC capital expenditures. Based on the range case, SCE forecasts a $37.8 billion total capital program for 2023 through 2028. This implies total weighted-average rate base incorporating CPUC- and FERC-jurisdictional capital expenditures increasing to $55.4 billion by 2028. 7

Table of Contents SCE's 2023 – 2028 forecast for major capital expenditures is set forth in the table below:


													Total
(in billions)	2023		2024		2025		2026		2027		2028		2023 – 2028
Traditional capital expenditures
Distribution	$	3.8	$	4.1	$	5.2	$	5.7	$	5.6	$	5.6	$	30.0

Total capital expenditures	$	5.5	$	6.0	$	7.5	$	8.2	$	8.3	$	7.8	$	43.3
Total capital expenditures using range case discussed above	$	5.3	$	5.6	$	6.6	$	6.9	$	6.9	$	6.5	$	37.8

In addition to the amounts presented in the table above, SCE expects to make additional CPUC capital investments, the recovery of which will be subject to future regulatory approval. This includes non-GRC programs including additional spending on an enterprise resource planning software implementation and an advanced metering infrastructure program. In addition, in May 2023, CAISO released its 2022 – 2023 Transmission Plan based on the CPUC's projections that it needs to add more than 40 gigawatts of new resources by 2032. As the incumbent transmission owner for a portion of these transmission projects, SCE expects to construct projects representing at least $2 billion of expenditures, most of which will be incurred beyond 2028.

Reflected below is SCE's weighted average annual rate base for 2023 – 2028 incorporating CPUC- and FERC- jurisdictional capital expenditures.


(in billions)	2023		2024		2025		2026		2027		2028
Rate base for expected capital expenditures	$	41.3	$	43.9	$	49.5	$	53.2	$	57.0	$	60.9
Rate base for expected capital expenditures using range case discussed above	$	41.1	$	43.3	$	48.0	$	50.4	$	52.8	$	55.4

For further information regarding the capital program, see "Liquidity and Capital Resources—SCE—Capital Investment Plan" below and "Management Overview—Capital Program" in the 2022 MD&A.

Customer-Funded Self-Insurance

In May 2023, the CPUC approved a joint petition for modification of the 2021 GRC decision filed by SCE, The Utility Reform Network and the Public Advocates Office, allowing SCE to expand its use of self-insurance. The approved self-insurance program will be in place for wildfires ignited between July 1, 2023 and December 31, 2024, and will be funded through CPUC-jurisdictional rates with $150 million collected for the second half of 2023 and, in the absence of wildfire-related claims, $300 million collected for 2024. The self-insurance program results in a reduction to current revenue requirements of $80 million in 2023 and, subject to adjustment, $160 million in 2024. If losses are accrued for wildfire-related claims, the program contains an adjustment mechanism that will increase rates 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 annual contribution of $12.5 million per policy year. If adopted in the 2025 GRC, this self-insurance framework will continue at least through 2028, supporting a self-insurance fund of up to $1.0 billion per policy year. SCE expects continuation of the customer-funded self-insurance framework to be adopted without protest in the 2025 GRC. Depending upon losses over time, customers will benefit further from SCE's wildfire self-insurance program as a result of not having to fund the recurring costs of SCE purchasing commercial wildfire insurance coverage. 8

2017/2018 Wildfire/Mudslide Events

As discussed in the 2022 Form 10-K, multiple lawsuits and investigations related to the 2017/2018 Wildfire/Mudslide Events have been initiated against SCE and Edison International. SCE has previously settled claims under the Local Public Entity Settlement, the TKM Subrogation Settlement, the Woolsey Subrogation Settlement and the SED Agreement. In addition, SCE has also entered into settlements with approximately 11,000 individual plaintiffs in the 2017/2018 Wildfire/Mudslide Events litigation as of September 30, 2023.

Each reporting period, management reviews its loss estimates for remaining alleged and potential claims related to the 2017/2018 Wildfire/Mudslide Events. Management’s third quarter 2023 review included a review of information obtained from settling claims in the 2017/2018 Wildfire/Mudslide Events litigations through the third quarter of 2023, including higher than expected costs to settle claims. Management’s review also included a review of information obtained in the third quarter of 2023 regarding the nature of claims remaining in the 2017/2018 Wildfire/Mudslide Events litigations. As a result of management's third quarter 2023 review, a $475 million increase in estimated losses for the 2017/2018 Wildfire/Mudslide Events as of September 30, 2023 was recorded. As a result, SCE recorded expected recoveries through FERC electric rates of $27 million against the charge. The resulting net charge to earnings was $448 million ($323 million after-tax).

Through September 30, 2023, SCE has accrued estimated losses of $9.3 billion, expected recoveries from insurance of $2.0 billion, all of which have been collected, and expected recoveries through FERC electric rates of $409 million, $358 million of which has been collected, related to the 2017/2018 Wildfire/Mudslide Events. The after-tax net charges to earnings recorded through September 30, 2023 have been $5.0 billion.

Estimated losses for the 2017/2018 Wildfire/Mudslide Events litigation are based on a number of assumptions and are subject to change as additional information becomes available. 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. For instance, SCE will receive additional information with respect to damages claimed as the claims mediation 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 the ongoing claims mediation processes, uncertainties related to the sufficiency of insurance held by plaintiffs, uncertainties related to the litigation processes, including whether 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 the 2017/2018 Wildfire/Mudslide Events, the complexities associated with fires that merge and whether inverse condemnation will be held applicable to SCE with respect to damages caused by the Montecito Mudslides, and the uncertainty as to how these factors impact future settlements.

As of September 30, 2023, SCE had paid $8.4 billion under executed settlements and had $209 million to be paid under executed settlements, including $65 million to be paid under the SED Agreement, related to the 2017/2018 Wildfire/Mudslide Events. After giving effect to all payment obligations under settlements entered into through September 30, 2023, Edison International's and SCE's best estimate of expected losses for remaining alleged and potential claims related to the 2017/2018 Wildfire/Mudslide Events was $728 million. 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.

SCE will seek CPUC-jurisdictional rate recovery of prudently-incurred losses and related costs realized in connection with the 2017/2018 Wildfire/Mudslide Events in excess of available insurance and FERC-jurisdictional recoveries, other than for any obligations under the SED Agreement. Based on Edison International's and SCE's current best estimate of expected losses for the 2017/2018 Wildfire/Mudslide Events, SCE currently expects to seek CPUC-jurisdictional rate recovery of approximately $6.4 billion of uninsured claims by filing applications with the CPUC. In August 2023, SCE filed the first of such cost recovery applications to seek rate recovery of $2.4 billion of prudently incurred losses related to the 9

Table of Contents Thomas Fire, the Koenigstein Fire and the Montecito Mudslides, consisting of $2.0 billion of uninsured claims and $0.4 billion of associated costs, including legal fees and financing costs. In its filing, SCE is also seeking capital recovery of approximately $65 million in restoration costs. SCE has requested that the CPUC issue a proposed decision on its application in February 2025. Because the CPUC's decision in a cost recovery proceeding involving SDG&E arising from several 2007 wildfires in SDG&E's service area is the only directly comparable precedent available, SCE believes that there is substantial uncertainty regarding how the CPUC will interpret and apply its prudency standard to an investor-owned utility in wildfire cost-recovery proceedings for fires ignited prior to the adoption of AB 1054 on July 12, 2019. Accordingly, while the CPUC has not made a determination regarding SCE's prudency relative to any of the 2017/2018 Wildfire/Mudslide Events, SCE is unable to conclude, at this time, that uninsured CPUC-jurisdictional wildfire-related costs related to the 2017/2018 Wildfire/Mudslide Events are probable of recovery through electric rates.

Safety Certification and Wildfire Mitigation Plan

SCE filed its 2023 – 2025 WMP in March 2023. In October 2023, the OEIS approved SCE’s 2023 – 2025 WMP, which approval is subject to CPUC ratification. SCE currently has a valid safety certification which will remain valid until the OEIS acts on SCE's September 12, 2023 request for a new safety certification.

RESULTS OF OPERATIONS ****

SCE

SCE's results of operations are derived mainly through two sources:

●	Earning activities – representing revenue authorized by the CPUC and the FERC, which is intended to provide SCE with a reasonable opportunity to recover its costs and earn a return on its net investment in generation, transmission and distribution assets. The annual revenue requirements are comprised of authorized operation and maintenance costs, depreciation, taxes and a return consistent with the capital structure. Also, included in earnings activities are revenue or penalties related to incentive mechanisms, other operating revenue, and regulatory charges or disallowances.
●	Cost-recovery activities – representing CPUC- and FERC- authorized balancing accounts, which allow for recovery of specific project or program costs, subject to reasonableness review or compliance with upfront standards, as well as non-bypassable rates collected for SCE Recovery Funding LLC. Cost-recovery activities include rates which provide recovery, subject to reasonableness review of, among other things, fuel costs, purchased power costs, public purpose related-program costs (including energy efficiency and demand-side management programs), certain operation and maintenance expenses (including vegetation management and wildfire insurance), and repayment of bonds and financing costs of SCE Recovery Funding LLC. SCE earns no return on these activities.

Earning Activities

Earning activities were primarily affected by the following:

●	Lower operating revenue of $63 million primarily due to the following:
●	A decrease of CPUC-related revenue of $139 million due to lower CSRP revenue requirements approved in 2023 than in 2022.
---	---
●	An increase of CPUC-related revenue of $107 million due to the escalation mechanism set forth in the 2021 GRC final decision.
---	---
●	A decrease of FERC-related revenue of $22 million primarily due to lower wildfire-related claims and expenses to be recovered in FERC revenues compared to 2022.
---	---
●	Lower operation and maintenance expenses of $121 million primarily due to the following:
---	---
●	In 2022, SCE recognized a charge of $95 million related to the POD on SCE's Upstream Lighting Program. This consisted of $76 million of disallowed costs reclassified from cost recovery activities and $19 million of fines.
---	---
●	Lower uncollectible expenses of $31 million primarily due to prior period expenses not subject to cost recovery recorded in 2022. A CPUC decision in 2022 required SCE to change its methodology for calculating the portion of uncollectibles expenses incremental to GRC authorized revenues.
---	---

Table of Contents

●	Wildfire-related claim charges were $479 million and $880 million in 2023 and 2022, respectively, primarily related to the 2017/2018 Wildfire/Mudslide Events. See "Notes to Consolidated Financial Statements—Note 12. Commitments and Contingencies—Contingencies—Southern California Wildfires and Mudslides."
●	Lower depreciation and amortization expense of $82 million primarily due to the CSRP decision received in 2022, which authorized SCE to recover $134 million of previously deferred depreciation expense in Q3 2022.
---	---
●	Higher interest expense of $100 million primarily due to higher interest rates on long-term debt and balancing account overcollections, as well as increased long-term borrowing.

Cost-Recovery Activities

Operating revenue and the corresponding operating expenses in cost-recovery activities were primarily affected by the following:

●	Lower purchased power and fuel costs of $373 million, primarily due to lower purchased power volumes, partially offset by hedging activities.

Table of Contents

●	Lower operation and maintenance costs of $187 million primarily due to:
●	A decrease of $244 million due to lower recognition of previously deferred wildfire mitigation expenses approved through Track 2 and Track 3 during 2023 than in 2022.
---	---
●	Lower insurance costs of $122 million due to expansion of SCE's use of customer-funded self-insurance for wildfire-related claims in July 2023.
---	---
●	A decrease of $109 million primarily due to authorization received in the first quarter of 2022 to recover 2020 and 2021 uncollectible costs that had been deferred as regulatory assets.
---	---
●	In May 2023, SCE recognized $205 million of previously deferred incremental wildfire insurance premiums that provided coverage for the last six months of 2020. For more information, see "Liquidity and Capital Resources—SCE—Regulatory Proceeding."
---	---
●	$76 million of disallowed costs were reclassified to earnings activities related to Upstream Lighting Program in 2022. See "—Earnings Activities" above.
---	---
●	Higher amortization expense of $19 million primarily due to recovery of expenses associated with AB 1054 Excluded Capital Expenditures financed through securitization.
---	---
●	Higher interest expenses of $14 million primarily due to recovery of expenses associated with AB 1054 Excluded Capital Expenditures financed through securitization.

Supplemental Operating Revenue Information

As a result of the CPUC-authorized decoupling mechanism, SCE revenues are not affected by changes in volume of retail electricity sales.

Income Taxes

Higher income tax expense of $176 million and $291 million for the three and nine months ended September 30, 2023, respectively, compared to the same period in 2022, was primarily driven by the increase in pre-tax income and lower tax benefit associated with CSRP revenue recovery in 2023. The effective tax rates were (0.4)% and (77.0)% for the three months ended September 30, 2023 and 2022, respectively. The effective tax rates were 7.9% and (77.4)% for the nine months ended September 30, 2023, and 2022, respectively. SCE’s effective tax rate is below the federal statutory rate of 21% for 2023 and 2022 primarily due to the CPUC's flow-through ratemaking treatment for the current tax benefit arising from certain property-related and other temporary differences, which reverse over time. The accounting treatment for these temporary differences results in recording regulatory assets and liabilities for amounts that would otherwise be recorded to deferred tax expense/benefit.

See "Notes to Consolidated Financial Statements—Note 8. Income Taxes" for a reconciliation of the federal statutory rate to the effective income tax rates.

Edison International Parent and Other

Results of operations for Edison International Parent and Other include amounts from other subsidiaries that are not reportable as segments, as well as intercompany eliminations. 14

The net loss attributable to common stock from operations of Edison International Parent and Other increased $36 million for the three months ended September 30, 2023 compared to the same period in 2022, primarily due to higher interest expense and lack of earnings from an EIS insurance contract. The net loss attributable to common stock from operations of Edison International Parent and Other increased $38 million for the nine months ended September 30, 2023 compared to the same period in 2022, primarily due to higher interest expense, partially offset by higher earnings from an EIS insurance contract. See "Notes to Consolidated Financial Statements—Note 12. Commitments and Contingencies" and "Notes to Consolidated Financial Statements—Note 17. Related Party Transactions."

LIQUIDITY AND CAPITAL RESOURCES

SCE

SCE's ability to operate its business, fund capital expenditures, and implement its business strategy is dependent upon its cash flows 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. SCE also has availability under its credit facility to fund cash requirements. SCE also expects to issue additional debt for general corporate purposes, and to finance and refinance debt issued for payment of claims and expenses related to the 2017/2018 Wildfire/Mudslide Events.

SCE has invested all $1.6 billion of the required AB 1054 Excluded Capital Expenditures. SCE issued securitized bonds in the amounts of $338 million, $533 million and $775 million in February 2021, February 2022 and April 2023, respectively, to finance these expenditures and related financing costs. SCE used the proceeds of the April 2023 securitized bonds to repay a term loan of $730 million prior to its maturity in May 2023. For further details, see "Notes to Consolidated Financial Statements—Note 5. Debt and Credit Agreements."

In the first quarter of 2023, Moody's upgraded SCE's credit rating from Baa2 to Baa1 and revised SCE's rating outlook from positive to stable. In the second quarter of 2023, Fitch upgraded SCE's credit rating from BBB- to BBB and revised SCE's rating outlook from positive to stable. The following tables summarizes SCE’s current long-term issuer credit ratings and outlook from the major credit rating agencies: 15

Table of Contents


	Moody's	Fitch	S&P
Credit Rating	Baa1	BBB	BBB
Outlook	Stable	Stable	Stable

SCE's credit ratings may be affected if, among other things, regulators fail to successfully implement AB 1054 in a consistent and credit supportive manner or the Wildfire Insurance Fund is depleted by claims from catastrophic wildfires. 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 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."

As discussed in the 2022 Form 10-K, the cost of capital adjustment mechanism set by the CPUC provides for an adjustment to SCE's authorized cost of capital that, when triggered, will impact SCE's results of operations and cash flows. In 2023, the cost of capital adjustment mechanism was triggered when the difference between the average Moody's Baa utility bond yield for the 12-month period from October 1, 2022 through September 30, 2023 and the mechanism's benchmark exceeded 100-basis points. As a result, absent CPUC action, SCE's CPUC-authorized ROE for 2024 will automatically increase from 10.05% to 10.75%. The adjustment will result in an increase to the GRC related revenue requirement for 2024 of $175 million. SCE's authorized costs of long-term debt and preferred equity will also be adjusted for 2024 to reflect the then-current embedded costs and projected interest rates. Intervenors may protest the increase to SCE's CPUC-authorized ROE. For further information see "Business—SCE— Overview of Ratemaking Process" in the 2022 Form 10-K.

Available Liquidity

At September 30, 2023, SCE had cash on hand of $317 million and approximately $2.5 billion available to borrow on its $3.4 billion revolving credit facility. The credit facility is available for borrowing needs until May 2027 and the aggregate maximum principal amount may be increased up to $4.0 billion, provided that additional lender commitments are obtained. In October 2023, SCE entered into agreements with certain lenders for bilateral unsecured standby letters of credit with a total capacity of $625 million that is uncommitted and supported by reimbursement agreements. For further details, see "Notes to Consolidated Financial Statements—Note 5. Debt and Credit Agreements."

SCE may finance balancing account undercollections, 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. As necessary, SCE will utilize its available liquidity, capital market financings, other borrowings or parent company contributions to SCE equity in order to meet its obligations as they become due, including costs related to the 2017/2018 Wildfire/Mudslide Events. For further information, see "Management Overview—Southern California Wildfires and Mudslides."

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 September 30, 2023, SCE's debt to total capitalization ratio was 0.57 to 1.

At September 30, 2023, SCE was in compliance with all financial covenants that affect access to capital.

Regulatory Proceedings

Wildfire Related Regulatory Proceedings

In response to the increase in wildfire activity, and faster progression of and increased damage from wildfires across SCE's service territory and throughout California, SCE has incurred wildfire mitigation, wildfire insurance and wildfire and drought restoration related spending at levels significantly exceeding amounts authorized in SCE's GRCs. 16

Table of Contents Wildfire Expense Memorandum Account

SCE tracks insurance premium costs related to wildfire liability insurance policies as well as other wildfire-related costs that are above authorized levels in its WEMA. SCE is not currently incurring premium costs for wildfire liability insurance policies due to the customer-funded self-insurance program. In May 2023, the CPUC authorized SCE to recover $207 million of costs recorded in WEMA. The costs are primarily related to incremental wildfire insurance premium expenses and associated costs for wildfire liability insurance policies that provide coverage for the last six months of 2020. The decision denied approximately $7 million of wildfire liability insurance coverage previously allocated to San Onofre, which SCE expects to be eligible for recovery from SCE customers in a future cost recovery proceeding.

2021 GRC Wildfire Mitigation Memorandum Account Balances

In October 2023, SCE requested authority to recover revenue requirements associated with 2022 operations and maintenance and capital expenditures above levels authorized in wildfire mitigation accounts and the vegetation management balancing account. The revenue requirement, including interest, is currently estimated at $382 million. Concurrent with the filing, SCE filed a motion for interim rate recovery to include $325 million of these costs and associated interest in revenue requirements beginning March 1, 2024.

CSRP

In March 2023, the CPUC approved SCE's second CSRP application to recover approximately $59 million of capital expenditures and $28 million of operation and maintenance expenses incurred from May 2021 to December 2021, resulting in a revenue requirement of $65 million. The decision also approved SCE seeking review and cost recovery of additional post-implementation CSRP costs incurred from January 2022 through December 2024 in its 2025 GRC filing.

ERRA Proceeding

In January 2023, as a result of undercollections in ERRA and PABA at the end of 2022 due to higher gas and power prices, SCE filed an expedited ERRA trigger application with the CPUC. In April 2023, the CPUC approved the trigger application, and SCE subsequently implemented an increased revenue requirement of $454 million over 12 months beginning June 1, 2023. See "Business—SCE—Overview of Ratemaking Process" in 2022 Form 10-K for further information regarding the ERRA trigger mechanism.

2024 FERC Formula Rate Annual Update

In June 2023, SCE provided its preliminary 2024 annual transmission revenue requirement update to interested parties. The update reflects a $1.1 billion transmission revenue requirement for 2024, $286 million or 20% lower than amounts included in 2023 annual rates. The decrease is primarily due to returning an overcollection based on actual 2022 costs and lower wildfire-related claims. SCE expects to file its 2024 annual update with the FERC by December 1, 2023 with the proposed rates effective January 1, 2024.

Capital Investment Plan

Major Transmission and Utility Owned Storage Projects

Alberhill System Project

The Alberhill System Project consists of constructing a new 500 kV substation, two 500 kV transmission lines to connect the proposed substation to the existing Serrano-Valley 500 kV transmission line, telecommunication equipment and subtransmission lines in western Riverside County. In June 2023, SCE filed an amended application for a certificate of public convenience and necessity ("CPCN") with technical design modifications and engineering refinements to the proposed project that decreases project costs and reduces GHG emissions. Accordingly, the direct expenditures of the project are 17

Table of Contents estimated to be reduced from $486 million to $472 million. See "Liquidity and Capital Resources—SCE—Capital Investment Plan" in the 2022 Form 10-K for further information.

Eldorado-Lugo-Mohave Upgrade Project

The total costs for the Eldorado-Lugo-Mohave Upgrade Project are expected to exceed amounts currently approved in the CPCN granted by the CPUC due to delays in regulatory approvals, contractor performance issues, supply chain constraints, COVID-19 impacts and the availability of CAISO outage windows. In May 2023, SCE filed a Petition for Modification of the decision that approved the project to increase the maximum reasonable and prudent cost for the project, which increased the direct expenditures from $247 million to $319 million. SCE expects the project to be in service in 2024. Additional work is also required to mitigate the impact of the project on nearby natural gas transmission lines and a further Petition for Modification is expected to be filed once the scope and cost of this work is known. See "Liquidity and Capital Resources—SCE—Capital Investment Plan" in the 2022 Form 10-K for further information.

Utility Owned Storage

As discussed in the 2022 Form 10-K, in October 2021, SCE contracted with Ameresco, Inc. ("Ameresco") for the construction of utility owned energy storage projects at three sites in SCE's service territory with an aggregate capacity of 537.5 MW.

In April 2023, Ameresco discovered damage to some of the equipment at one of the projects which makes up 225 MW of the 537.5 MW aggregate capacity. SCE received a notice of potential force majeure event from Ameresco noting that Ameresco is performing further analyses on the cause of the damage and asserting that rainstorms at the project site may have caused or contributed to the damage. Ameresco is evaluating corrective action in response to the damage discovered in April 2023.

Ameresco has advised SCE that it currently expects the 112.5 MW project and the 200 MW project to be in-service prior to the end of 2023. SCE believes that there is significant risk of delay beyond Ameresco's projected in-service dates.

Decommissioning of San Onofre

As discussed in the 2022 Form 10-K, in February 2022, SCE filed its application in the 2021 NDCTP with the CPUC requesting reasonableness review of approximately $570 million (SCE share in 2022 dollars) of recorded San Onofre Units 2 and 3 decommissioning costs incurred during the period 2018 to 2020. In May 2023, SCE entered into a settlement with the relevant intervenors under which, subject to CPUC approval, SCE agreed to a disallowance in the 2021 NDCTP of approximately $30 million. SCE has accrued approximately $30 million related to the 2021 NDCTP.

SCE Dividends

As discussed in the 2022 Form 10-K, the CPUC regulates SCE's capital structure which limits the dividends it may pay to its shareholders. In August 2023, the CPUC issued a decision on SCE's application to the CPUC for an extension of the waiver of compliance with its equity ratio requirement that allows SCE to exclude from its equity ratio calculations (i) net charges accrued in connection with the 2017/2018 Wildfire/Mudslide Events and (ii) debt issued for the purpose of paying claims related to the 2017/2018 Wildfire/Mudslide Events up to an amount equal to the net charges accrued in connection with the 2017/2018 Wildfire/Mudslide Events. Under the decision, effective as of the beginning of the new cost of capital cycle on January 1, 2023, the CPUC also authorized SCE to exclude from its equity ratio calculations debt that exceeds the net charges accrued in connection with the 2017/2018 Wildfire/Mudslide Events due to the timing difference between the wildfire claims payment and the realization of the cash tax benefits. The temporary exclusion will lapse on August 31, 2025 or when determinations regarding cost recovery for the 2017/2018 Wildfire/Mudslide Events are made, whichever comes earlier. If the CPUC has not made determinations regarding cost recovery by August 31, 2025, SCE is permitted to file another application for a waiver of compliance with its equity ratio requirement. For information on the California law requirements on the declaration of dividends, see "Liquidity and Capital Resources—SCE—SCE Dividends" in the 2022 Form 10-K. 18

Table of Contents Margin and Collateral Deposits

Certain derivative instruments, power and energy procurement contracts and other contractual arrangements contain collateral requirements. In addition, certain environmental remediation obligations require financial assurance that may be in the form of collateral postings. Future collateral requirements may differ from the requirements at September 30, 2023, 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.

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 September 30, 2023, 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 derivative 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. Furthermore, 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 occurs.

Edison International Parent and Other

In the next 12 months, Edison International expects to fund its net cash requirements through cash on hand, dividends from SCE, and capital market and bank financings. Edison International 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 September 30, 2023, Edison International Parent and Other had cash on hand of $129 million and $1.1 billion available to borrow on its $1.5 billion revolving credit facility. The credit facility is available for borrowing needs until May 2027 and the aggregate maximum principal amount may be increased up to $2.0 billion, provided that additional lender commitments are obtained. For further information, see "Notes to Consolidated Financial Statements—Note 5. Debt and Credit Agreements."

In March 2023, Edison International Parent issued $500 million of junior subordinated notes, due in 2053, which provided approximately $250 million of equity content as viewed by rating agencies. Edison International expects to raise any additional equity this year through its internal programs, which are estimated to generate approximately $100 million. The 19

Table of Contents total expected equity content is consistent with the $300 million to $400 million of equity content identified in Edison International's 2023 financing plan.

In October 2023, Edison International commenced a tender offer to purchase its outstanding Series A and Series B Preferred Stock for a maximum aggregate purchase price in cash of up to $750 million, plus accrued dividends. Edison International intends to pay the consideration payable and the fees and expenses incurred with cash on hand and proceeds of debt issuances, which may include commercial paper and junior subordinated notes. For further information, see "Notes to 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 "Liquidity and Capital Resources—SCE—SCE Dividends" in the 2022 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 2022 Form 10-K.

Edison International Parent's credit facility requires a consolidated debt to total capitalization ratio as defined in the applicable agreements of less than or equal to 0.70 to 1. At September 30, 2023, Edison International's consolidated debt to total capitalization ratio was 0.63 to 1.

At September 30, 2023, Edison International Parent was in compliance with all financial covenants that affect access to capital.

In the first quarter of 2023, Moody's upgraded Edison International's credit rating from Baa3 to Baa2 and revised Edison International's rating outlook from positive to stable. In the second quarter of 2023, Fitch upgraded Edison International's credit rating from BBB- to BBB and revised Edison International's rating outlook from positive to stable. The following table summarizes Edison International Parent's current long-term issuer credit ratings and outlook from the major credit rating agencies:


	Moody's	Fitch	S&P
Credit Rating	Baa2	BBB	BBB
Outlook	Stable	Stable	Stable

Edison International Parent's credit ratings may be affected if, among other things, regulators fail to successfully implement AB 1054 in a consistent and credit supportive manner or the Wildfire Insurance Fund is depleted by claims from catastrophic wildfires. 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

On August 16, 2022, the IRA was signed into law. The law imposes a 15% corporate alternative minimum tax ("CAMT") on adjusted financial statement income ("AFSI") of corporations with average AFSI exceeding $1.0 billion over a specified 3-year period. The CAMT was effective beginning January 1, 2023. Based on the current interpretation of the law and historical financial data, Edison International estimates that it will exceed the $1.0 billion threshold and be subject to CAMT on its consolidated Federal tax returns beginning in 2025. SCE also expects to be subject to CAMT on its stand-alone Federal return beginning in 2025. 20

Table of Contents The law also includes significant extensions, expansions, and enhancements of numerous energy-related investment tax credits, as well as creating new credits applicable to electricity production which may apply to SCE's capital expenditures. Under the IRA, SCE expects to generate investment tax credits related to its utility owned storage projects, which will accrue to the benefit of its customers.

2	Changes in working capital items include receivables, accrued unbilled revenue, inventory, amortization of prepaid expenses, accounts payable, tax receivables and payables, derivative assets and liabilities and other current assets and liabilities.
---	---
3	The amount in 2023 represents payments of $747 million for 2017/2018 Wildfire/Mudslide Events and $16 million for Post-2018 Wildfires, partially offset by an increase in wildfire estimated losses of $689 million. The amount in 2022 is primarily related to an increase in wildfire estimated losses of $1.9 billion, partially offset by payments of $1.6 billion for 2017/2018 Wildfire/Mudslide Events.
---	---
4	Includes nuclear decommissioning trusts. See "Nuclear Decommissioning Activities" below for further information. In addition, 2023 and 2022 amounts also include outflow from increase in wildfire insurance receivables of $87 million and $392 million, respectively.
---	---

Net cash provided by operating activities was impacted by the following:

Net income and non-cash items increased in 2023 by $901 million primarily due to revenue from the escalation mechanism set forth in the 2021 GRC final decision, higher interest income on balancing account undercollections and lower wildfire estimated losses, partially offset by higher interest expense.

The net changes in cash resulting from working capital were outflows of $1,120 million and $1,064 million during the nine months ended September 30, 2023 and 2022, respectively. The net cash outflows were primarily due to net increases in customer receivables and unbilled revenue of approximately $1.0 billion and $1.3 billion for 2023 and 2022, respectively. 21

Table of Contents Net cash provided by regulatory assets and liabilities, including changes in net undercollections recorded in balancing accounts, was $705 million and $1,032 million during the nine months ended September 30, 2023 and 2022, respectively. SCE has a number of balancing and memorandum accounts, which impact cash flows based on differences between timing of collection of amounts through rates and accrual expenditures. Cash flows were primarily impacted by the following:

2023

●	Net undercollections for ERRA, PABA and NSGBA decreased by $419 million primarily due to recovery of prior year undercollections, partially offset by current year undercollections due to lower than forecast sales volume driven by mild weather.
●	Increased overcollections of $228 million for the public purpose and energy efficiency programs primarily due to program spending timing.
---	---
●	Increased overcollections of $104 million for GHG revenue mainly related to GHG auction revenue received, partially offset by climate credits provided to customers.
---	---
●	Net undercollections of BRRBA decreased by $102 million primarily due to recovery of prior year undercollections from various tracks of the 2021 GRC, partially offset by current year undercollections due to lower sales volume driven by mild weather and inclusion in BRRBA of expense previously deferred in WEMA that was authorized for collection in customer rates starting June 2023.
---	---

2022

●	Net undercollections of BRRBA decreased by $159 million primarily due to current year overcollections due to higher sales volume and average rates due to extreme heat in California and recovery of prior year undercollections, including 2021 GRC authorized additional revenue requirement for the first nine months of 2021 to be collected over a 27-month period starting October 2021. These higher collections were partially offset by inclusion in BRRBA of $401 million of expense authorized under Track 2 for collection in customer rates starting March 2022 over a 36-month period and a revenue requirement of approximately $400 million authorized under Track 3 for collection in customer rates starting October 2022 over a 36-month period.
●	Undercollections decreased by $394 million related to wildfire risk mitigation and restoration memorandum and balancing accounts as a result of approval to recover costs in Track 2 and Track 3, which were transferred to BRRBA for recovery as mentioned above, partially offset by additional WEMA and wildfire risk mitigation and restoration costs incurred.
---	---
●	Net undercollections for ERRA, PABA and NSGBA increased by $298 million primarily due to current year undercollections due to higher energy prices and power purchase load, partially offset by current year overcollections due to higher volume and average rates driven by extreme heat in California and recovery of prior PABA and NSGBA undercollections.
---	---
●	Increased overcollections of $537 million for the public purpose and energy efficiency programs primarily due to lower program spending due to timing and increased sales volume.
---	---

Cash flows used in investing activities are primarily due to total capital expenditures of $4.0 billion and $4.2 billion for nine months ended September 30, 2023 and 2022, respectively. In addition, SCE had a net redemption of nuclear decommissioning trust investments of $94 million and $81 million during the nine months ended September 30, 2023 and 2022, respectively. See "Nuclear Decommissioning Activities" below for further discussion.

Nuclear Decommissioning Activities

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


	Nine months ended September 30,
(in millions)	2023		2022
Net cash used in operating activities:
Net earnings from nuclear decommissioning trust investments	$	77	$	59
SCE's decommissioning costs		(167)		(161)

Proceeds from sale of investments		3,223		3,120
Purchases of investments		(3,129)		(3,039)

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 ($167 million and $161 million in 2023 and 2022, respectively) and reimbursements to SCE from the nuclear decommissioning trust ($171 million and $140 million in 2023 and 2022, respectively). 23

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 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, 2022 financial statement data was derived from the audited financial statements, but does not include all disclosures required by GAAP for complete annual financial statements. Certain prior period amounts have been conformed to the current period's presentation, including the separate presentation of derivative assets and liabilities on Edison International's and SCE's consolidated statements of cash flows.

Cash, Cash Equivalents and Restricted Cash

Cash 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. The cash equivalents were as follows:


	Edison International				SCE
	September 30,		December 31,		September 30,		December 31,
(in millions)	2023		2022		2023		2022
Money market funds	$	120	$	784	$	—	$	647

Cash is temporarily invested until required for check clearing. Checks issued, but not yet paid by the financial institution, are reclassified from cash to accounts payable at the end of each reporting period. 35

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 and 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 trends, including unemployment rates and any likelihood of recession for the region.

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

Table of Contents 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. See Note 13 for further information.

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


	Three months ended September 30,				Nine months ended September 30,
(in millions, except per-share amounts)	2023		2022		2023		2022
Basic earnings (loss) per share:
Net income (loss) attributable to common shareholders	$	155	$	(128)	$	819	$	197
Net income (loss) available to common shareholders	$	155	$	(128)	$	819	$	197
Weighted average common shares outstanding		383		382		383		381
Basic earnings (loss) per share	$	0.40	$	(0.33)	$	2.14	$	0.52
Diluted earnings (loss) per share:
Net income (loss) attributable to common shareholders	$	155	$	(128)	$	819	$	197
Net income (loss) available to common shareholders	$	155	$	(128)	$	819	$	197
Income impact of assumed conversions		—		—		1		—
Net income (loss) available to common shareholders and assumed conversions	$	155	$	(128)	$	820	$	197
Weighted average common shares outstanding		383		382		383		381
Incremental shares from assumed conversions		2		1		2		1
Adjusted weighted average shares – diluted		385		383		385		382
Diluted earnings (loss) per share	$	0.40	$	(0.33)	$	2.13	$	0.52

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 3,231,385 and 5,089,280 shares of common stock for the three months ended September 30, 2023 and 2022, respectively, and 3,230,603 and 5,204,369 shares of common stock for the nine months ended September 30, 2023 and 2022, 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 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 2023 Formula Rate Update

In November 2022, SCE filed its 2023 annual update with the FERC with the proposed rates effective January 1, 2023, subject to settlement procedures and refund. Pending resolution of the FERC formula rate proceedings, SCE recognized revenue in the first nine months of 2023 based on the FERC 2023 annual update rate, subject to refund.

Leases

During the quarter ended September 30, 2023, one SCE 15-year power purchase agreement ("PPA"), accounted for as a long-term operating lease, commenced and resulted in $226 million additions in right-of-use assets and lease liabilities. 37

Table of Contents Edison Carrier Solutions

SCE operates commercial telecommunications service under the name of Edison Carrier Solutions ("ECS"), leveraging the temporarily available capacity of SCE's telecommunications network. As technology evolves, management is implementing strategic shifts in ECS services, including potential disposition of assets and ceasing to offer certain wire data services. ECS has notified affected customers of its intent to discontinue certain services over time and gave customers the option to discontinue those services. As a result of customer cancellations in the second quarter of 2023, materials and supplies inventory supporting data services are expected to be sold instead of placed into service and have been written-down to net realizable value, resulting in a charge of $13 million. Labor and other costs of $4 million previously recorded as construction work in progress for projects no longer probable of completion were also charged to expense in the period.

Subsequent Event

In October 2023, SCE entered into two PPAs, which are subject to CPUC approval, with expected initial delivery dates commencing in 2027 and 2028, respectively. The undiscounted future minimum expected payments for these contracts are $48 million in 2027 and $3.0 billion thereafter. 38

Note 3.Variable Interest Entities

A VIE is defined as a legal entity that meets one of two conditions: (1) the equity owners do not have sufficient equity at risk, or (2) the holders of the equity investment at risk, as a group, lack any of the following three characteristics: decision-making 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. Commercial and operating activities include construction, operation and maintenance, fuel procurement, plant dispatch and compliance with regulatory and contractual requirements. 42

Table of Contents Variable Interest in VIEs that are Consolidated

SCE Recovery Funding LLC is a bankruptcy remote, wholly owned special purpose subsidiary, consolidated by SCE. SCE Recovery Funding LLC is a VIE and SCE is the primary beneficiary. SCE Recovery Funding LLC was formed in 2021 for the purpose of issuing and servicing securitized bonds related to SCE's AB 1054 Excluded Capital Expenditures.

SCE Recovery Funding LLC has issued a total of $1.6 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 territory ("Recovery Property"), associated with the AB 1054 Excluded Capital Expenditures, 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. For further details, see Note 5.

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

Variable Interest in VIEs that are not Consolidated

Power Purchase Agreements

SCE has PPAs that are classified as variable interests in VIEs, including agreements through which SCE provides the natural gas to fuel the plants, fixed price contracts for renewable energy, and resource adequacy agreements that, upon the seller's election, include the purchase of energy at fixed prices. SCE has concluded that it is not the primary beneficiary of these VIEs since it does not control the commercial and operating activities of these entities. Since payments for capacity are the primary source of income, the most significant economic activity for these VIEs is the operation and maintenance of the power plants, which SCE does not perform.

As of the balance sheet date, the carrying amount of assets and liabilities included in SCE's 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 2022 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 3,443 MW and 3,901 MW at September 30, 2023 and 2022, respectively. The amounts that SCE paid to these projects were $191 million and $252 million for the three months ended September 30, 2023 and 2022, respectively, and $476 million and $460 million for the nine months ended September 30, 2023 and 2022, respectively. These amounts are recoverable in customer rates, subject to reasonableness review. 43

Table of Contents Unconsolidated Trusts of SCE

SCE Trust II, Trust III, Trust IV, Trust V, and Trust VI were formed in 2013, 2014, 2015, 2016, and 2017, respectively, for the exclusive purpose of issuing the 5.10%, 5.75%, 5.375%, 5.45%, and 5.00% trust preference securities, respectively ("trust securities"). The trusts are VIEs. SCE has concluded that it is not the primary beneficiary of these VIEs as it does not have the obligation to absorb the expected losses or the right to receive the expected residual returns of the trusts. SCE Trust II, Trust III, Trust IV, Trust V and Trust VI issued to the public trust securities in the face amounts of $400 million, $275 million, $325 million, $300 million, and $475 million (cumulative, liquidation amounts of $25 per share), respectively, and $10,000 of common stock each to SCE. The trusts invested the proceeds of these trust securities in Series G, Series H, Series J, Series K, and Series L Preference Stock issued by SCE in the principal amounts of $400 million, $275 million, $325 million, $300 million, and $475 million (cumulative, $2,500 per share liquidation values), respectively, which have substantially the same payment terms as the respective trust securities.

The Series G, Series H, Series J, Series K, and Series L Preference Stock and the corresponding trust securities do not have a maturity date. Upon any redemption of any shares of the Series G, Series H, Series J, Series K, or Series L Preference Stock, a corresponding dollar amount of trust securities will be redeemed by the applicable trust. The applicable trust will make distributions at the same rate and on the same dates on the applicable series of trust securities, if and when the SCE board of directors declares and makes dividend payments on the related Preference Stock. The applicable trust will use any dividends it receives on the related Preference Stock to make its corresponding distributions on the applicable series of trust securities. If SCE does not make a dividend payment to any of these trusts, SCE would be prohibited from paying dividends on its common stock. SCE has fully and unconditionally guaranteed the payment of the trust securities and trust distributions, if and when SCE pays dividends on the related Preference Stock.

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 September 30, 2023 and December 31, 2022, nonperformance risk was not material for Edison International and 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 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 includes 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. 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. 45

Uncommitted Letters of Credit Subsequent to September 30, 2023

In October 2023, SCE entered into agreements with certain lenders for bilateral unsecured standby letters of credit ("SBLC") with a total capacity of $625 million that is uncommitted and supported by reimbursement agreements. The SBLCs are not subject to any collateral or security requirements.

I e **** **Note 6.**Derivative Instruments

Derivative financial instruments are used to manage exposure to commodity price risk. These risks are managed in part by entering into forward commodity transactions, including options, swaps and futures. 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.

Commodity Price Risk

Commodity price risk represents the potential impact that can be caused by a change in the market value of a particular commodity. SCE's electricity price exposure arises from energy purchased from and sold to wholesale markets as a result of differences between SCE's load requirements and the amount of energy delivered from its generating facilities and PPAs. SCE's natural gas price exposure arises from natural gas purchased for the Mountainview power plants, Peaker plants and Qualifying Facilities contracts where pricing is based on a monthly natural gas index and PPAs in which SCE has agreed to provide the natural gas needed for generation, referred to as tolling arrangements.

Credit and Default Risk

Credit and default risk represent the potential impact that can be caused if a counterparty were to default on its contractual obligations and SCE would be exposed to spot markets for buying replacement power and natural gas or selling excess power and natural gas. In addition, SCE would be exposed to the risk of non-payment of accounts receivable, primarily related to the sales of excess power and natural gas and realized gains on derivative instruments. 49

Table of Contents Certain power and gas contracts contain master netting agreements or similar agreements, which generally allow counterparties subject to the agreement to offset amounts when certain criteria are met, such as in the event of default. The objective of netting is to reduce credit exposure. Additionally, to reduce SCE's risk exposures, counterparties may be required to pledge collateral depending on the creditworthiness of each counterparty and the risk associated with the transaction.

Certain power and gas contracts contain a provision that requires SCE to maintain an investment grade rating from the major credit rating agencies that have credit ratings for SCE, referred to as a credit-risk-related contingent feature. If SCE's credit rating were to fall below investment grade, SCE may be required to post additional collateral to cover derivative liabilities and the related outstanding payables. The net fair value of all derivative liabilities with these credit-risk-related contingent features was less than $1 million as of September 30, 2023 and December 31, 2022, for which SCE posted no collateral and collateral of $24 million for its outstanding payables as of September 30, 2023 and December 31, 2022, respectively. If the credit-risk-related contingent features underlying these agreements were triggered on September 30, 2023, SCE would be required to post collateral of $1 million, most of which is related to outstanding payables.

Fair Value of Derivative Instruments

SCE presents its derivative assets and liabilities, recorded at fair value, on a net basis on its consolidated balance sheets when subject to master netting agreements or similar agreements. Derivative positions are also offset against margin and cash collateral deposits. In addition, SCE has provided collateral in the form of letters of credit. Collateral requirements can vary depending upon the level of unsecured credit extended by counterparties, changes in market prices relative to contractual commitments and other factors. 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:

At September 30, 2023, SCE posted and accrued $110 million of cash collateral, of which $40 million was offset against derivative liabilities and $70 million was reflected in "Other current assets" on SCE's consolidated balance sheets.

Financial Statement Impact of Derivative Instruments

SCE recognizes realized gains and losses on derivative instruments as purchased power expense and expects that such gains or losses will be part of the purchased power costs recovered from customers. As a result, realized gains and losses do not 50

Table of Contents affect earnings, but may temporarily affect cash flows. Due to the expected future recovery from customers, unrealized gains and losses are recorded as regulatory assets and liabilities and therefore, also do not affect earnings. The remaining effects of derivative activities and related regulatory offsets are reported in cash flows from operating activities in SCE’s consolidated statements of cash flows.

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

Note 7.Revenue

SCE's revenue is disaggregated by two revenue sources:

●

Earning activities – representing revenue authorized by the CPUC and FERC, which is intended to provide SCE with a reasonable opportunity to recover its costs and earn a return on its net investment in generation, transmission and distribution assets. The annual revenue requirements are comprised of authorized operation and maintenance costs, depreciation, taxes and a return consistent with the capital structure. Also, included in earnings activities are revenue or penalties related to incentive mechanisms, other operating revenue, and regulatory charges or disallowances.

●

Cost-recovery activities – representing CPUC- and FERC- authorized balancing accounts, which allow for recovery of specific project or program costs, subject to a reasonableness review or compliance with upfront standards, as well as non-bypassable rates collected for SCE Recovery Funding LLC. Cost-recovery activities include rates which provide recovery, subject to a reasonableness review of, among other things, fuel costs, purchased power costs, public purpose related-program costs (including energy efficiency and demand-side management programs), certain operation and maintenance expenses and repayment of bonds and financing costs of SCE Recovery Funding LLC. SCE earns no return on these activities.

The CPUC requires flow-through ratemaking treatment for the current tax benefit arising from certain property-related and other temporary differences which reverse over time. Flow-through items reduce current authorized revenue requirements in SCE's rate cases and result in a regulatory asset for recovery of deferred income taxes in future periods. The difference between the authorized amounts as determined in SCE's rate cases, adjusted for balancing and memorandum account 52

Table of Contents activities, and the recorded flow-through items also result in increases or decreases in regulatory assets with a corresponding impact on the effective tax rate to the extent that recorded deferred amounts are expected to be recovered in future rates. For further information, see Note 11.

Tax Disputes

In 2020, Edison International recorded favorable tax positions in connection with the Edison Mission Energy bankruptcy that were fully reserved. Based on information identified during the second quarter of 2023, the Company wrote off the total claim and related reserve in the amount of approximately $268 million.

Tax years that remain open for examination by the IRS and the California Franchise Tax Board ("FTB") are 2020 – 2022 and 2013 – 2022, respectively.

Trust fund earnings (based on specific identification) increase the trust fund balance and the asset retirement obligation ("ARO") regulatory liability. Unrealized holding gains, net of losses, were $1.5 billion and $1.6 billion at September 30, 2023 and December 31, 2022, respectively.

Trust assets are used to pay income taxes arising from trust investing activity. Deferred tax liabilities related to net unrealized gains were $313 million and $321 million at September 30, 2023 and December 31, 2022, respectively. Accordingly, the fair value of trust assets available to pay future decommissioning costs, net of deferred income taxes, totaled $3.6 billion at both September 30, 2023 and December 31, 2022. 54

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

Table of Contents Note 12. Commitments and Contingencies

Indemnities

Edison International and SCE have various financial and performance guarantees and indemnity agreements which are issued in the normal course of business.

Edison International and SCE have agreed to provide indemnifications 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 with respect to assets sold 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. 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.

Southern California Wildfires and Mudslides

California has experienced unprecedented weather conditions in recent years due to climate change, and wildfires in SCE's territory, including those where SCE's equipment may be alleged to be associated with the fire's ignition, have caused loss of life and substantial damage in recent years. SCE's service territory remains susceptible to additional wildfire activity.

Numerous claims related to wildfire events have been initiated against SCE and Edison International. Edison International and SCE have incurred material losses in connection with the 2017/2018 Wildfire/Mudslide Events (defined below), which are described below. In addition, SCE's equipment has been, and may further be, alleged to be associated with wildfires that have originated in Southern California subsequent to 2018.

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. 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 57

Table of Contents settlement of disputed claims, may require estimated losses to be accrued under accounting standards. 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: estimates of known and expected claims by third parties based on currently available information, opinions of counsel regarding litigation risk, the status of and developments in the course of litigation, and prior experience litigating and settling wildfire litigation claims. 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.

2017/2018 Wildfire/Mudslide Events

Wildfires in SCE's territory 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 California Department of Forestry and Fire Protection ("CAL FIRE"), have determined that the largest of the 2017 fires in SCE's territory originated on December 4, 2017, in the Anlauf Canyon area of Ventura County (the investigating agencies refer to this fire as the "Thomas Fire"), followed shortly thereafter by a second fire that originated near Koenigstein Road in the City of Santa Paula (the "Koenigstein Fire"). The December 4, 2017 fires eventually burned substantial acreage in both Ventura and Santa Barbara Counties. 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 territory, known as the "Woolsey Fire," originated in Ventura County and burned acreage in both Ventura and Los Angeles Counties. 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.

As described below, 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 (the "Montecito Mudslides") 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 Thomas Fire, the Koenigstein Fire, the Montecito Mudslides and the Woolsey Fire are each referred to as a "2017/2018 Wildfire/Mudslide Event," and, collectively, referred to as the "2017/2018 Wildfire/Mudslide Events."

Recent Developments

As of September 30, 2023, SCE had paid $8.4 billion under executed settlements, had $209 million to be paid under executed settlements, including $65 million to be paid under the SED Agreement (as defined below), and had $728 million of 58

Table of Contents estimated losses for remaining alleged and potential claims reflected on its consolidated balance sheets related to the 2017/2018 Wildfire/Mudslide Events. As of the same date, SCE had assets for expected recoveries through FERC electric rates of $51 million on its consolidated balance sheets and had exhausted expected insurance recoveries related to the 2017/2018 Wildfire/Mudslide Events.

The estimated losses for the 2017/2018 Wildfire/Mudslide Events do not include an estimate of potential losses related to certain alleged and potential claims made by the California Governor's Office of Emergency Service ("Cal OES") seeking recovery on behalf of itself and 30 state and local government entities that did not pursue their own suits against SCE, but sustained damage in the 2017/2018 Wildfire/Mudslide Events and received funding through the Federal Emergency Management Agency ("FEMA") that was dispersed by the Cal OES. As of the filing of this report, SCE has not concluded that losses related to FEMA funds disbursed by Cal OES are probable.

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. Due to the number of uncertainties and possible outcomes related to the 2017/2018 Wildfire/Mudslide Events litigation, Edison International and SCE cannot estimate the upper end of the range of reasonably possible losses that may be incurred.

The CPUC and FERC may not allow SCE to recover uninsured losses through electric rates if it is determined that such losses were not prudently incurred. SCE will seek rate recovery of prudently incurred losses and related costs realized in connection with the 2017/2018 Wildfire/Mudslide Events in excess of available insurance, other than for any obligations under the SED Agreement (as defined below). See "Loss Estimates for Third Party Claims and Potential Recoveries from Insurance and through Electric Rates" below for additional information.

External Investigations and Internal Review

The VCFD and CAL FIRE have jointly issued reports concerning their findings regarding the causes of the Thomas Fire and the Koenigstein Fire. The reports did not address the causes of the Montecito Mudslides. SCE has also received a non-final redacted draft of a report from the VCFD regarding Woolsey Fire (the "Redacted Woolsey Report"). SCE cannot predict when the VCFD will release its final report regarding the Woolsey Fire.

The CPUC's Safety and Enforcement Division ("SED") conducted investigations to assess SCE's compliance with applicable rules and regulations in areas impacted by the Thomas, Koenigstein and Woolsey Fires. As discussed below, in October 2021, SCE and the SED executed the SED Agreement (as defined below) to resolve the SED's investigations into the 2017/2018 Wildfire/Mudslide Events.

The California Attorney General's Office has completed its investigation of the Thomas Fire and the Woolsey Fire without pursuing criminal charges. 59

Table of Contents SCE's internal review into the facts and circumstances of each of the 2017/2018 Wildfire/Mudslide Events is complex and time consuming. 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 processes.

Thomas Fire

On March 13, 2019, the VCFD and CAL FIRE jointly issued a report concluding, after ruling out other possible causes, that the Thomas Fire was started by SCE power lines coming into contact during high winds, resulting in molten metal falling to the ground. However, the report does not state that their investigation found molten metal on the ground. At this time, based on available information, SCE believes that it is likely that its equipment was not associated with the ignition of the Thomas Fire. Based on publicly available radar data showing a smoke plume in the Anlauf Canyon area emerging in advance of the report's indicated start time and other evidence, SCE believes that the Thomas Fire started at least 12 minutes prior to any issue involving SCE's system and at least 15 minutes prior to the start time indicated in the report. SCE is continuing to assess the extent of damages that may be attributable to the Thomas Fire.

Koenigstein Fire

On March 20, 2019, the VCFD and CAL FIRE jointly issued a report finding that the Koenigstein Fire was caused when an energized SCE electrical wire separated and fell to the ground along with molten metal particles and ignited the dry vegetation below. SCE believes that its equipment was associated with the ignition of the Koenigstein Fire. SCE is continuing to assess the extent of damages that may be attributable to the Koenigstein Fire.

Montecito Mudslides

SCE's internal review includes inquiry into whether the Thomas and/or Koenigstein Fires proximately caused or contributed to the Montecito Mudslides, whether, and to what extent, the Thomas and/or Koenigstein Fires were responsible for the damages in the Montecito area and other factors that potentially contributed to the losses that resulted from the Montecito Mudslides. Many other factors, including, but not limited to, weather conditions and insufficiently or improperly designed and maintained debris basins, roads, bridges and other channel crossings, could have proximately caused, contributed to or exacerbated the losses that resulted from the Montecito Mudslides.

At this time, based on available information, SCE has not been able to determine whether the Thomas Fire or the Koenigstein Fire, or both, were responsible for the damages in the Montecito area. In the event that SCE is determined to have caused the fire that spread to the Montecito area, SCE cannot predict whether, if fully litigated, the courts would conclude that the Montecito Mudslides were caused or contributed to by the Thomas and/or Koenigstein Fires or that SCE would be liable for some or all of the damages caused by the Montecito Mudslides.

Woolsey Fire

SCE's internal review into the facts and circumstances of the Woolsey Fire is ongoing. SCE has reported to the CPUC that there was an outage on SCE's electric system in the vicinity of where the Woolsey Fire reportedly began on November 8, 2018. SCE is aware of witnesses who saw fire in the vicinity of SCE's equipment at the time the fire was first reported. While SCE did not find evidence of downed electrical wires on the ground in the suspected area of origin, it observed a pole support wire in proximity to an electrical wire that was energized prior to the outage.

The Redacted Woolsey Report states that the VCFD investigation team determined that electrical equipment owned and operated by SCE was the cause of the Woolsey Fire. Absent additional evidence, SCE believes that it is likely that its equipment was associated with the ignition of the Woolsey Fire. SCE expects to obtain and review additional information and materials in the possession of CAL FIRE and others during the course of its internal review and the Woolsey Fire litigation process, including SCE equipment that has been retained by CAL FIRE. 60

Table of Contents Litigation

Multiple 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 September 30, 2023, in addition to the outstanding claims of approximately 2,000 individual plaintiffs, there were alleged and potential claims of certain public entity plaintiffs, including Cal OES and Cal Fire, outstanding. The litigation could take a number of years to be resolved because of the complexity of the matters and number of plaintiffs.

On October 4, 2018, the Los Angeles Superior Court denied Edison International's and SCE's challenge to the application of inverse condemnation to SCE with respect to the Thomas and Koenigstein Fires and, on February 26, 2019, the California Supreme Court denied SCE's petition to review the Superior Court's decision. In April 2022, following a stipulated judgment entered against SCE in the TKM litigation, SCE filed an appeal related to inverse condemnation in the California Court of Appeal.

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. These cross-claims in the Montecito Mudslides litigation were not released as part of the Local Public Entity Settlements (as defined below).

Settlements

In the fourth quarter of 2019, SCE paid $360 million to a number of local public entities to resolve those parties' collective claims arising from the 2017/2018 Wildfire/Mudslide Events (the "Local Public Entity Settlements").

In the third quarter of 2020, Edison International and SCE entered into an agreement (the "TKM Subrogation Settlement") under which all of the insurance subrogation plaintiffs' in the Thomas Fire, Koenigstein Fire and Montecito Mudslides litigation (the "TKM Subrogation Plaintiffs") collective claims arising from the Thomas Fire, Koenigstein Fire or Montecito Mudslides have been resolved. Under the TKM Subrogation Settlement, SCE paid the TKM Subrogation Plaintiffs an aggregate of $1.2 billion in October 2020 and also agreed to pay $0.555 for each dollar in claims to be paid by the TKM Subrogation Plaintiffs to their policy holders on or before July 15, 2023, up to an agreed upon cap.

In January 2021, Edison International and SCE entered into an agreement (the "Woolsey Subrogation Settlement") under which all of the insurance subrogation plaintiffs' in the Woolsey Fire litigation (the "Woolsey Subrogation Plaintiffs") collective claims arising from the Woolsey Fire have been resolved. Under the Woolsey Subrogation Settlement, SCE paid the Woolsey Subrogation Plaintiffs an aggregate of $2.2 billion in March and April 2021. SCE has also agreed to pay $0.67 for each dollar in claims to be paid by the Woolsey Subrogation Plaintiffs to their policy holders on or before July 15, 2023, up to an agreed upon cap.

As of September 30, 2023, SCE has also entered into settlements with approximately 11,000 individual plaintiffs in the 2017/2018 Wildfire/Mudslide Events litigation. In 2022, 2021 and 2020, SCE entered into settlements with individual plaintiffs in the 2017/2018 Wildfire/Mudslide Events litigation under which it agreed to pay an aggregate of approximately $1.7 billion, $1.7 billion and $300 million, respectively, to those individual plaintiffs. In the first, second and third quarters of 2023, SCE entered into settlements with individual plaintiffs in the 2017/2018 Wildfire/Mudslide Events litigation under which it agreed to pay an aggregate of approximately $148 million, $278 million and $316 million, respectively, to those individual plaintiffs. The statutes of limitations for individual plaintiffs in the 2017/2018 Wildfire/Mudslide Events have expired. 61

Table of Contents Edison International and SCE did not admit wrongdoing or liability as part of any of the settlements described above. Other claims and potential claims related to the 2017/2018 Wildfire/Mudslide Events remain. SCE continues to explore reasonable settlement opportunities with other plaintiffs in the outstanding 2017/2018 Wildfire/Mudslide Events litigation.

SED Agreement

In October 2021, SCE and the SED executed an agreement (the "SED 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 comprised 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 $375 million of third-party uninsured claims payments. 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's obligations under the SED Agreement commenced on August 15, 2022, when CPUC approval of the SED Agreement became final and non-appealable. SCE did not admit imprudence, negligence or liability with respect to the 2017/2018 Wildfire/Mudslide Events in the SED Agreement.

Loss Estimates for Third Party Claims and Potential Recoveries from Insurance and through Electric Rates

At September 30, 2023 and December 31, 2022, Edison International's and SCE's consolidated balance sheets included fixed payments to be made under executed settlement agreements and accrued estimated losses of $937 million and $1.1 billion, respectively, for the 2017/2018 Wildfire/Mudslide Events. The following table presents changes in estimated losses since December 31, 2022:


(in millions)

2	At September 30, 2023, $150 million in current liabilities, wildfire-related claims, on Edison International's and SCE's consolidated balance sheets consisted of $144 million of settlements executed and $6 million of short term payables under the SED Agreement in connection with the 2017/2018 Wildfire/Mudslide Events. At September 30, 2023, the $1,583 million included in deferred credits and other liabilities, wildfire-related claims, on Edison International's and SCE's consolidated balance sheets included Edison International's and SCE's best estimate of expected losses for remaining alleged and potential claims related to the 2017/2018 Wildfire/Mudslide Events of $728 million, $59 million of long term payables under the SED Agreement and other wildfire-related claims estimates of $796 million.
---	---

For the three and nine months ended September 30, 2023 and 2022, Edison International's and SCE's consolidated statements of income included charges for the estimated losses, net of expected recoveries from insurance and FERC customers, related to the 2017/2018 Wildfire/Mudslide Events as follows: 62

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.

In total, through September 30, 2023, SCE has accrued estimated losses of $9.3 billion, has paid or is obligated to pay approximately $8.6 billion in settlements, including $65 million to be paid under the SED Agreement, and has recovered $2.0 billion from its insurance carriers in relation to the 2017/2018 Wildfire/Mudslide Events.

Recovery of SCE's losses realized in connection with the 2017/2018 Wildfire/Mudslide Events in excess of available insurance is subject to approval by regulators. Under accounting standards for rate-regulated enterprises, SCE defers costs as regulatory assets when it concludes that such costs are probable of future recovery in electric rates. SCE utilizes objectively determinable evidence to form its view on probability of future recovery. The only directly comparable precedent in which a California investor-owned utility has sought recovery for uninsured wildfire-related costs is San Diego Gas & Electric's ("SDG&E") requests for cost recovery related to 2007 wildfire activity, where the FERC allowed 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 SDG&E did not meet the CPUC's prudency standard. As a result, while SCE does not agree with the CPUC's decision, it believes that the CPUC's interpretation and application of the prudency standard to SDG&E creates substantial uncertainty regarding how that standard will be applied to an investor-owned utility in wildfire cost-recovery proceedings for fires ignited prior to July 12, 2019. SCE will continue to evaluate the probability of recovery based on available evidence, including judicial, legislative and regulatory decisions, including any CPUC decisions illustrating the interpretation and/or application of the prudency standard when making determinations regarding recovery of uninsured wildfire-related costs. While the CPUC has not made a determination regarding SCE's prudency relative to any of the 2017/2018 Wildfire/Mudslide Events, SCE is unable to conclude, at this time, that uninsured CPUC-jurisdictional wildfire-related costs are probable of recovery through electric rates. SCE would record a regulatory asset at the time it obtains sufficient information to support a conclusion that recovery is probable.

In August 2023, SCE filed an application ("TKM Application") with the CPUC to seek rate recovery of $2.4 billion of prudently incurred losses related to the Thomas Fire, the Koenigstein Fire and the Montecito Mudslides, consisting of $2.0 billion of uninsured claims and $0.4 billion of associated costs, including legal fees and financing costs. The TKM Application seeks recovery of amounts paid as of July 31, 2023. In the application, SCE proposed a true-up process for claims payments made after that date, and associated costs.

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 wildfire and mudslide related costs and has recorded total expected recoveries of $409 million within the FERC balancing account. This was the FERC portion of the total estimated losses accrued. As of September 30, 2023, collections have reduced the regulatory assets remaining in the FERC balancing account to $51 million.

As of September 30, 2023, SCE has $173 million in assets recorded in property, plant and equipment in relation to restoration costs related to the 2017/2018 Wildfire/Mudslide Events. These assets would be impaired if the restoration costs are permanently disallowed by the CPUC in cost recovery proceedings. In its TKM Application, SCE is seeking capital recovery 63

Table of Contents of approximately $65 million in restoration costs related to the Thomas and Koenigstein Fires. SCE expects to seek to recover the costs incurred for reconstructing its system and restoring service to structures that were damaged or destroyed by the Woolsey Fire in the future.

Post-2018 Wildfires

Several wildfires have significantly impacted portions of SCE's service territory after 2018 (the wildfires that originated in Southern California after 2018 where SCE's equipment may be alleged to be associated with the fire's ignition are referred to collectively as the "Post-2018 Wildfires"). Numerous claims related to the Post-2018 Wildfires have been initiated against SCE and Edison International. The SED is also conducting investigations with respect to several Post-2018 Wildfires.

During the nine months ended September 30, 2023, SCE accrued estimated losses of $124 million for claims related to the Post-2018 Wildfires, against which SCE has recorded expected recoveries from insurance of $114 million. The resulting net charge to earnings was $10 million ($7 million after-tax).

Through September 30, 2023, SCE has recorded total estimated losses of $820 million, expected recoveries from insurance and third parties of $587 million and expected recoveries through electric rates of $166 million related to the Post-2018 Wildfires. The after-tax net charges to earnings recorded through September 30, 2023 have been $48 million.

As of September 30, 2023, SCE had paid $30 million under executed settlements related to the Post-2018 Wildfires and Edison International's and SCE's estimated losses for remaining alleged and potential claims related to the Post-2018 Wildfires was $790 million. As of the same date, SCE had assets for expected recoveries through insurance and third parties of $560 million **** and through electric rates of $166 million on its consolidated balance sheets related to the Post-2018 Wildfires.

Expected recoveries from insurance recorded for the Post-2018 Wildfires are supported by SCE's insurance coverage for multiple policy years. While Edison International and SCE may incur material losses in excess of the amounts accrued for certain of the Post-2018 Wildfires, Edison International and SCE expect that any 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 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 fire fighters. In August 2023, SCE received a signed report of investigation from the Los Angeles Fire Department ("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. A jury trial in the Saddle Ridge Fire litigation is currently set for May 2024. Based on pending litigation and without considering insurance recoveries, it is reasonably possible that SCE will incur a material loss in connection with the Saddle Ridge Fire, but the range of reasonably possible losses that could be incurred cannot be estimated at this time. SCE has not accrued a charge for potential losses relating to the Saddle Ridge Fire.

2020 Bobcat Fire

The "Bobcat Fire" was reported in the vicinity of Cogswell Dam in Los Angeles County in September 2020. The United States Forest Service ("USFS") has reported that the Bobcat Fire burned approximately 116,000 acres in Los Angeles County, destroyed an estimated 87 homes, one commercial property and 83 minor structures, damaged an estimated 28 homes and 19 minor structures, and resulted in injuries to six firefighters. In addition, fire authorities have estimated suppression costs at approximately $80 million. An investigation into the cause of the Bobcat Fire was led by the USFS. In 64

Table of Contents May 2023, SCE received a report of investigation from the USFS, in which the USFS finds that the Bobcat Fire was caused when an SCE electrical wire made contact with a tree limb. A jury trial in the Bobcat Fire litigation is currently set for April 2024. 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 material charges for potential losses relating to the Bobcat Fire. The accrued charges correspond to the lower end of the estimated range of reasonably possible losses that may be incurred in connection with the Bobcat Fire and are subject to change as additional information becomes available. While Edison International and SCE may incur a material loss in excess of the amount accrued, they cannot estimate the upper end of the range of reasonably possible losses that may be incurred.

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 is being led by the OCFA. The OCFA has retained SCE equipment in connection with its investigation. An inverse condemnation liability bench trial in the Coastal Fire litigation has been set for April 29, 2024. 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 material charges for potential losses relating to the Coastal Fire. The accrued charges correspond to the lower end of the estimated range of reasonably possible losses that may be incurred in connection with the Coastal Fire and are subject to change as additional information becomes available. While Edison International and SCE may incur a material loss in excess of the amount accrued, they cannot estimate the upper end of the range of reasonably possible losses that may be incurred.

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 a SCE circuit in the area experienced an anomaly (relay) approximately 8 minutes prior to the reported start time of the fire. An investigation into the cause of the Fairview Fire is being led by CAL FIRE. CAL FIRE has retained SCE equipment in connection with its investigation. A trial for bellwether plaintiffs in the Fairview Fire litigation has been set for September 2024. 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 material charges for potential losses relating to the Fairview Fire. The accrued charges correspond to the lower end of the estimated range of reasonably possible losses that may be incurred in connection with the Fairview Fire and are subject to change as additional information becomes available. While Edison International and SCE may incur a material loss in excess of the amount accrued, they cannot estimate the upper end of the range of reasonably possible losses that may be incurred.

Loss Estimates for Third Party Claims and Potential Recoveries from Insurance and through Electric Rates

At September 30, 2023 and December 31, 2022, Edison International's and SCE's consolidated balance sheets included accrued estimated losses of $790 million and $682 million, respectively, for the Post-2018 Wildfires. 65

("EIS"), a wholly-owned subsidiary of Edison International, paid $3 million insurance for the three and nine months ended September 30, 2023 and $9 million insurance for the three and nine months ended September 30, 2022. These insurance payments were included in the insurance recovery of SCE but were excluded from that of Edison International.
---	---

Recovery of SCE's losses realized in connection with the Post-2018 Wildfires in excess of available insurance is subject to approval by regulators. The CPUC and FERC may not allow SCE to recover uninsured losses through electric rates if it is determined that such losses were not prudently incurred. Under accounting standards for rate-regulated enterprises, SCE defers costs as regulatory assets when it concludes that such costs are probable of future recovery in electric rates. SCE utilizes objectively determinable evidence to form its view on the probability of future recovery. As discussed above, there 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. This evidence 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. 66

Table of Contents Each of the Post-2018 Wildfires was ignited after July 12, 2019, and SCE has held a valid safety certificate since July 15, 2019. While a California investor-owned utility has not yet sought 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 investor-owned utilities holding a safety certificate 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 raised. As such, SCE has concluded, at this time, that both uninsured CPUC-jurisdictional and uninsured FERC-jurisdictional wildfire-related costs related to the Post-2018 Wildfires that it has deferred as regulatory assets are probable of recovery through electric rates. **** As of September 30, 2023, SCE has recorded total expected recoveries related to the Post-2018 Wildfires of $152 million within the WEMA and risk management balancing account and $14 million within the FERC balancing account. SCE will continue to evaluate the probability of recovery based on available evidence, including regulatory decisions, including any CPUC decisions illustrating the interpretation and/or application of the prudency standard under AB 1054, and, for each applicable fire, evidence that could cast serious doubt as to the reasonableness of SCE's conduct relative to that fire.

Wildfire Insurance Coverage

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, with $150 million collected for the second half of 2023 and, in the absence of wildfire-related claims, $300 million collected for 2024. If losses are accrued for wildfire-related claims for wildfires that occur between July 1, 2023 and the end of 2024, 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 annual contribution of $12.5 million per policy year. If adopted in the 2025 GRC, this self-insurance framework would continue through at least 2028, supporting a self-insurance fund of up to $1.0 billion per policy year. SCE’s self-insurance program meets its obligation to maintain reasonable insurance coverage under AB 1054 for the July 1, 2023 through June 30, 2024 period.

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 $100 million of self-insured retention and co-insurance per fire, which results in aggregate net coverage of approximately $937 million. Of this coverage, approximately $102 million is provided by EIS and approximately $835 million is provided by other commercial insurance carriers (commercial insurance carriers other than EIS are referred to herein as "Third-Party Commercial Insurers").

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 $100 million of self-insured retention and co-insurance per fire, as well as additional co-insurance of up to $63 million for the policy year, which resulted in net coverage of approximately $875 million provided by Third-Party Commercial Insurers and $28 million provided by EIS for part of the policy year.

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 Third-Party Commercial Insurers. SCE's wildfire insurance expense for the July 1, 2021 through June 30, 2022 policy period was approximately $437 million, of which $413 million was paid to Third-Party Commercial Insurers. The difference between the Third-Party Commercial Insurer cost and total cost in both policy years was paid in premiums to EIS. Wildfire insurance premiums paid for the July 1, 2021 through June 30, 2022 and July 1, 2022 through June 30, 2023 policy periods are being recovered through customer rates. See Note 17 for further information.

Edison International and SCE record a receivable for insurance recoveries when recovery of a recorded loss is determined to be probable.

Environmental Remediation

SCE records its environmental remediation and restoration 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 67

Table of Contents 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 lower 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 September 30, 2023, SCE's recorded estimated minimum liability to remediate its 26 identified material sites (sites with a liability balance at September 30, 2023, in which the upper end of the range of expected costs is at least $1 million) was $251 million, including $159 million related to San Onofre. In addition to these sites, SCE also has 12 immaterial sites with a liability balance as of September 30, 2023, for which the total minimum recorded liability was $3 million. Of the $254 million total environmental remediation liability for SCE, $233 million has been recorded as a regulatory asset. SCE expects to recover $36 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 $197 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 $120 million and $5 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 40 years. Remediation costs for each of the next five years are expected to range from $9 million to $26 million. Costs incurred for the nine months ended September 30, 2023 and 2022 were $9 million and $5 million, respectively.

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 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 $24 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 $16.5 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 68

Table of Contents 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 Issuances

As of September 30, 2023, Edison International had not issued any shares through its "at-the-market" ("ATM") program established in August 2022. Under the ATM program, Edison International may sell shares of its common stock having an aggregate sales price of up to $500 million. Edison International has no obligation to sell the remaining shares available under the ATM program.

Edison International continued to settle its ongoing common stock requirements of various internal programs through issuance of new common stock. During the three months ended September 30, 2023, 204,724 shares of common stock were issued as stock compensation awards for net cash receipts of $11 million, 61,922 shares of new common stock were issued in lieu of distributing $4 million to shareholders opting to receive dividend payments in the form of additional common stock, 20,400 shares of common stock were issued to employees through the 401(k) defined contribution savings plan for net cash receipts of $1 million as dividend payments and 29,442 shares of common stock were issued to employees through the Employee Stock Purchase Plan for net cash receipts of $2 million.

During the nine months ended September 30, 2023, 1,013,203 shares of common stock were issued as stock compensation awards for net cash receipts of $50 million, 189,927 shares of new common stock were issued in lieu of distributing $13 million to shareholders opting to receive dividend payments in the form of additional common stock, 90,400 shares of common stock were issued to employees through the 401(k) defined contribution savings plan for net cash receipts of $6 million as dividend payments, 55,923 shares of common stock were issued to employees through the Employee Stock Purchase Plan for net cash receipts of $4 million and 9,905 shares of common stock were issued to employees through voluntary cash purchases for net cash receipts of $1 million.

Offer to Purchase Outstanding Preferred Stock Subsequent to September 30, 2023

On October 11, 2023, Edison International commenced a tender offer to purchase its outstanding 5.00% Fixed-Rate Reset Cumulative Perpetual Preferred Stock, Series B ("Series B Preferred Stock") and its 5.375% Fixed-Rate Reset Cumulative Perpetual Preferred Stock, Series A ("Series A Preferred Stock") for a maximum aggregate purchase price in cash of up to $750 million, plus accrued dividends. The consideration for the securities tendered and accepted for purchase will equal $895 per $1,000 liquidation preference of Series B Preferred Stock and $915 per $1,000 liquidation preference of Series A Preferred Stock, plus, in each case, accrued dividends. The tender offer will expire on November 8, 2023. For further information about Series A Preferred Stock and Series B Preferred Stock, see "Notes to Consolidated Financial Statements—Note 14.

Note 17. Related-Party Transactions

SCE has previously purchased wildfire liability insurance from EIS, a wholly-owned subsidiary of Edison International. In July 2022, SCE purchased wildfire liability insurance for premiums of $273 million, from EIS for the period to June 30, 2023. EIS fully reinsured the exposure for these policies through the commercial reinsurance market, with reinsurance limits and premiums equal to those of the insurance purchased by SCE, except for a contract for a premium of $93 million under which EIS provided insurance protection to SCE. SCE recorded the premium as insurance expense and recorded equal revenue due to customer funding through regulatory cost recovery mechanisms, therefore there was no earnings impact on SCE's consolidated statement of income. EIS recorded the premium as insurance revenue. On the Edison International consolidated statement of income, the EIS insurance revenue eliminated with SCE's insurance expense, therefore the SCE customer revenues increased the earnings of Edison International. SCE did not have insurance expense and corresponding revenue for the three months ended September 30, 2023, and the amount of insurance expense and corresponding revenue was $44 million for the nine months ended September 30, 2023.

The related-party transactions included in SCE's consolidated balance sheets for wildfire-related insurance purchased from EIS and related expected insurance recoveries were as follows:

Table of Contents LEGAL PROCEEDINGS

2017/2018 Wildfire/Mudslide Events

Multiple 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 October 25, 2023, in addition to the outstanding claims of approximately 2,000 individual plaintiffs, there were alleged and potential claims of certain public entity plaintiffs, including Cal OES and Cal Fire, outstanding. The litigation could take a number of years to be resolved because of the complexity of the matters and number of plaintiffs.

As of October 25, 2023, SCE was aware of approximately 100 pending unsettled lawsuits representing approximately 500 individual plaintiffs related to the Thomas and Koenigstein Fires naming SCE as a defendant. Approximately 60 of the approximately 100 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 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. Some individual plaintiffs have opted to pursue trial outside of the settlement program.

Approximately 40 of the approximately 100 pending unsettled individual plaintiff lawsuits mentioned in the paragraph above allege that SCE has responsibility for the Thomas and/or Koenigstein Fires and that the Thomas and/or Koenigstein Fires proximately caused the Montecito Mudslides, resulting in the plaintiffs' claimed damages. Many of the Montecito Mudslides lawsuits also name Edison International as a defendant based on its ownership and alleged control of SCE. In addition to other causes of action, some of the Montecito Mudslides lawsuits also allege personal injury and wrongful death.

As of October 25, 2023, SCE was aware of approximately 250 currently pending unsettled lawsuits representing approximately 1,500 individual plaintiffs related to the Woolsey Fire naming SCE as a defendant. Approximately 230 of the 250 lawsuits also name Edison International as a defendant based on its ownership and alleged control of SCE. At least one of the lawsuits was filed as a purported class action. The lawsuits, which have been filed in the superior courts of Ventura and Los Angeles Counties allege, among other things, negligence, inverse condemnation, personal injury, wrongful death, trespass, private nuisance, and violations of the public utilities and health and safety codes. SCE and certain of the individual plaintiffs in the Woolsey Fire litigation have been pursuing settlements of claims under a mediation program adopted to promote an efficient and orderly settlement process. Some individual plaintiffs may opt to pursue trial outside of the settlement program.

The Thomas and Koenigstein Fires and Montecito Mudslides lawsuits are being coordinated in the Los Angeles Superior Court. The Woolsey Fire lawsuits have also been coordinated in the Los Angeles Superior Court.

For further information, including regarding settlement activity related to the 2017/2018 Wildfire/Mudslide Events, see "Notes to Consolidated Financial Statements—Note 12. Commitments and Contingencies—Contingencies—Southern California Wildfires and Mudslides."

Environmental Proceedings

Each of Edison International and SCE have elected to disclose environmental proceedings described in Item 103(c)(3)(iii) of Regulation S-K unless it reasonably believes that such proceeding will result in no monetary sanctions, or in monetary sanctions, exclusive of interest and costs, of less than $1,000,000. 73

Exhibit 10.1 EDISON INTERNATIONAL AND SOUTHERN CALIFORNIA EDISON COMPANY

DIRECTOR COMPENSATION SCHEDULE

As Adopted August 24, 2023

Effective October 1, 2023, except as otherwise provided below, non-employee Directors of Edison International (“EIX”) and/or Southern California Edison Company (“SCE”) will receive the annual retainers, expense reimbursements and equity-based awards described below as compensation for serving as a Director. The equity-based award provisions described below are effective as to awards in connection with the election or reelection of Directors on or after August 24, 2023.

Directors who are employees of EIX or SCE shall not receive additional compensation for serving as Directors (other than participation in the EIX Director Matching Gifts Program). Directors who serve on both the EIX Board and the SCE Board, and their corresponding Board Committees, will not receive additional compensation for serving on two Boards.

Annual Retainers

Board Retainer – Each Director will receive an annual board retainer of $127,500 to be paid in advance in quarterly installments of $31,875 for any calendar quarter or portion thereof during which the individual serves as a Director.

Board Committee Chair Retainer –The Director who serves as the Chair of the Audit and Finance Committee will receive an additional annual retainer of $25,000. Each Director who serves as the Chair of the Compensation and Executive Personnel Committee, the Nominating and Governance Committee, or the Safety and Operations Committee will receive an additional annual retainer of $20,000. The Committee Chair retainers shall be paid in advance in equal quarterly installments for any calendar quarter or portion thereof during which the Director serves as a Committee Chair.

Chair of EIX Board Retainer – A non-employee Director who serves as the Chair of the EIX Board shall receive an additional annual retainer of $92,500. The retainer shall be paid in advance in equal quarterly installments for any calendar quarter or portion thereof during which the Director serves as the Chair of the EIX Board.

The quarterly retainer installments will be paid on the first business day of the calendar quarter. Initial quarterly retainer installments will be paid as soon as possible following the effective date of the election.

Meeting Fees

Except as may otherwise be approved by the Board, no meeting fees shall be paid to Directors.

Expense Reimbursement

A Director will promptly be reimbursed after submitting to the Corporate Secretary a statement of expenses, supported by receipts and any other requested documentation, for (i) reasonable expenses incurred by the Director to attend Board meetings, Committee meetings, or business meetings attended on behalf of the corporation in his or her capacity as a Director, and (ii) reasonable program fees and expenses incurred by the Director to attend director education programs that are relevant to service on the Board.^1^

Equity-Based Awards^2^

Equity-based awards (“Awards”) will be granted under and subject to the terms of the EIX 2007 Performance Incentive Plan or a successor plan (the “Plan”), except that any award payable in cash will be deemed paid outside of the Plan. The Awards consist of fully vested Edison International deferred stock units (“DSUs”) and/or Edison International common stock (“Common Stock”). Each DSU represents the value of one share of Common Stock and will be credited to the Director’s account under the EIX 2008 Director Deferred Compensation Plan (the “DDCP”) and subject to its terms. DSUs include dividend equivalent rights that are converted to additional DSUs. The number of DSUs or shares of Common Stock awarded to a Director in any particular instance will be calculated by dividing the applicable equity award amount to be granted on that date (expressed in dollars and determined as set forth below, the “Award Amount”) by the fair market value of a share of Common Stock as of that date, rounded up to the nearest whole share. Fair market value for these purposes shall be determined in accordance with the Plan. Each Award will be subject to terms and conditions approved in advance by the Board.

Initial Election and Annual Reelection Awards – Each Director initially elected or reelected to the Board will receive Common Stock and/or DSUs with an aggregate Award Amount of $177,500, except that Initial Election Awards will be subject to proration as provided below. The date of grant shall be the date of such initial election or reelection. The portion of the award to be granted in Common Stock and/or DSUs shall be determined in accordance with the DDCP.

^1^

To the extent any expense reimbursements provided for in this Director Compensation Schedule are taxable to a Director and provide for a deferral of compensation within the meaning of Section 409A of the Internal Revenue Code, the Director shall complete all steps required for reimbursement so as to facilitate payment, and any such reimbursements shall be paid to the Director on or before December 31 of the calendar year following the calendar year in which the expense was incurred. Such reimbursements shall not be subject to liquidation or exchange for other benefits, and the expenses eligible for reimbursement in one calendar year shall not affect the expenses eligible for reimbursement in any other calendar year.

^2^

With respect to equity-based awards approved and granted by the EIX Board under current and prior compensation plans of EIX, this Director Compensation Schedule does not alter the intent of the EIX Board to have the awards and subsequent transactions by the Directors occurring pursuant to the awards continue to comply with and be exempt under Section 16(b) of the Securities Exchange Act of 1934, as amended, pursuant to Rule 16b-3 promulgated thereunder (or any successor provision thereto).

---

Additional Award to Chair of EIX Board – Upon the initial appointment of a non-employee Director as Chair of the EIX Board, the Director will receive an Additional Award of Common Stock and/or DSUs with an Award Amount of $92,500 subject to proration as provided below, the date of grant of which shall be the effective date of such appointment.

If a non-employee Director serving as Chair of the EIX Board is reelected to the EIX Board and is reappointed or otherwise remains Chair of the EIX Board following such reelection, then that Director will receive an Additional Award of Common Stock and/or DSUs with an Award Amount of $92,500 (in addition to the Annual Reelection Award Amount of $177,500, for a total Award Amount of $270,000), the grant date of which shall be the date of such reelection.

The portion of the Additional Award to be granted in Common Stock and/or DSUs shall be determined in accordance with the DDCP.

Proration of Certain Awards. The Initial Election and first Additional Award amounts provided for above are subject to proration if the grant date of the Award occurs (i) in the second quarter of EIX’s fiscal year and after the date of EIX’s annual meeting of shareholders for that year, (ii) in the third quarter of EIX’s fiscal year, or (iii) in the fourth quarter of EIX’s fiscal year. In determining the Award Amount as to any such Award, the applicable dollar amount set forth above will be multiplied by a percentage determined in accordance with the table set forth below.

If the grant date of the award occurs:	Then the applicable percentage is:
In the first quarter of EIX’s fiscal year, or in the second quarter of EIX’s fiscal year and on or before the date of EIX’s annual meeting of shareholders for that year	100% (no proration)
In the second quarter of EIX’s fiscal year and after the date of EIX’s annual meeting of shareholders for that year	75%
In the third quarter of EIX’s fiscal year	50%
In the fourth quarter of EIX’s fiscal year	25%

However, if a non-employee Director receives an Initial Election and/or first Additional Award during a particular EIX fiscal year before the date of EIX’s annual meeting of

shareholders for that year, the Director will not receive that same Award Amount again if he or she is reelected as a Director in that fiscal year.^3^

EIX Affiliate Boards – SCE non-employee Directors who do not serve on the EIX Board will receive Awards equal in amount to EIX non-employee Directors if the SCE Board authorizes such compensation. Differing amounts of SCE Awards, and Awards for non-employee directors of other EIX affiliates, may only be made with additional approval of the EIX Board.

Director Deferred Compensation Plan

Each non-employee Director of EIX or SCE is eligible to participate in the DDCP in accordance with its terms. The DDCP allows participating Directors the opportunity to make pre-tax deferrals from annual retainers, meeting fees (if any), and equity-based awards. The DDCP sets forth the terms of participation, including, if applicable, mandatory deferral of compensation that is otherwise payable to the Director for the year of initial election.

Matching Gift Program

Directors of EIX and SCE are eligible to participate in the EIX Director Matching Gifts Program.

^3^

For example, if a non-employee Director is initially elected to the Board in the first quarter of EIX’s fiscal year or in the second quarter before the date of EIX’s annual meeting of shareholders for that year, and is then reelected to the Board on the date of EIX’s annual meeting of shareholders for that year, the Director would receive an Initial Award in connection with his or her initial election to the Board, but would not receive an Annual Reelection Award in connection with that annual meeting. If that Director is initially appointed as Chair of the EIX Board at that annual meeting, he or she would receive the first Additional Award.

Exhibit 10.2 EDISON INTERNATIONAL

EXECUTIVE INCENTIVE COMPENSATION PLAN

As Amended and Restated Effective January 1, 2024

WHEREAS, it has been determined that it is in the best interest of Edison International ("EIX") and its affiliates to offer and maintain competitive executive compensation programs designed to attract and retain qualified executives;

WHEREAS, it has been determined that providing financial incentives to executives that reinforce and recognize corporate, organizational and individual performance and accomplishments will enhance the financial and operational performance of EIX and its affiliates; and

WHEREAS, it has been determined that an incentive compensation program would encourage the attainment of short-term corporate goals and objectives;

NOW, THEREFORE, the Edison International Executive Incentive Compensation Plan has been established by the Compensation and Executive Personnel Committee of the Board of Directors originally effective January 1, 1997, and made available to eligible executives of EIX and its participating affiliates subject to the following terms and conditions:

1. Definitions. When capitalized herein, the following terms are defined as indicated:

“Board” means the Board of Directors of a Company (or a committee thereof acting within its delegated authority).

“CEO” means the chief executive officer of a Company.

“Code” means the Internal Revenue Code of 1986, as amended.

“Company” means EIX or a participating affiliate.

“Committee” means the Compensation and Executive Personnel Committee of the EIX Board of Directors. Where the context requires with respect to officers and other participating employees of SCE, “Committee” shall also mean the Compensation and Executive Personnel Committee of the SCE Board.

“Covered Officer” means an individual who is a “Covered Officer” of EIX or SCE as defined in the EIX or SCE Committee Charter.

“Covered Participant” means an individual who is or was (i) a vice president or officer with a more senior title at EIX, SCE or Edison Energy Support Services, LLC (“EESS”), (ii) the

	1

chief financial officer of Edison Energy, LLC (“Edison Energy”), or (iii) a senior vice president or officer with a more senior title at Edison Energy.

“EIX CEO” means the chief executive officer of EIX.

“Misconduct” as to a Covered Participant means (a) the occurrence of any act or omission by the Covered Participant that could reasonably be expected to result in (or has resulted in) such Covered Participant’s conviction, plea of no contest, plea of nolo contendere, or imposition of unadjudicated probation for any felony or for any indictable offense or crime involving moral turpitude; (b) the Covered Participant’s commission of an act of fraud, embezzlement, misappropriation, or breach of fiduciary duty against a Company or any of its subsidiaries or affiliates or any of their officers, directors, employees, customers, suppliers, insurers or agents; or (c) any violation by the Covered Participant of a provision in the EIX Code of Conduct, as in effect from time to time (or, as to a Covered Participant employed by an affiliate of EIX who is subject to a Code of Conduct maintained by an affiliate of EIX at the applicable time, the Covered Participant’s violation of a provision of such affiliate’s Code of Conduct as then in effect).

“Participant” means the CEO, president, executive vice presidents, senior vice presidents, elected vice presidents, and senior managers whose participation in this Plan has been approved by the Committee, the EIX CEO or the Board.

“Plan” means this Edison International Executive Incentive Compensation Plan.

“Recoupment Administrator” means the Committee or other body, individual or individuals, as the case may be, to whom the authority to determine whether to recoup compensation due to misconduct has been delegated by the Committee for purposes of this Plan.

“SCE” means Southern California Edison Company.

2. Eligibility. Except as otherwise expressly provided herein, to be eligible for any incentive award with respect to a particular calendar year (the “Performance Year”), an individual must (a) have been employed by the Company as a Participant for the entire Performance Year, and (b) continue to be employed by EIX, SCE, or one of their respective subsidiaries through the date that the Company pays incentive awards under the Plan with respect to that Performance Year generally (which, as provided in Section 5 below, occurs within two and one-half months following the end of the Performance Year) (the “Vesting Date”). Except as otherwise expressly provided herein, in no event will a Participant or any other individual be entitled to, or be considered to have earned all or any portion of, an incentive award under the Plan with respect to a particular Performance Year unless (x) the Participant satisfies both of the eligibility requirements set forth in the preceding sentence and (y) solely with respect to a Participant who is a Covered Participant, the Covered Participant does not engage in Misconduct during or following the particular Performance Year.

	2

In the event an individual first becomes a Participant after the start of the Performance Year but the individual otherwise satisfies the eligibility requirements set forth in the preceding paragraph, a pro-rata award may be made at the discretion of the Committee or an individual (and, if applicable, Board) having the authority to approve the Participant's award pursuant to Section 5 below. **** Pro-rata awards may be distributed to Participants who during the Performance Year retired, died, or had their employment transferred between a Company and a non-participating affiliate of EIX. A full award may be distributed to a Participant who was employed by the Company as a Participant for the entire Performance Year but who was not employed by EIX, SCE, or one of their respective subsidiaries through the applicable Vesting Date due to retirement or death. The determination of whether any pro-rata or full award will be paid in any such circumstances will be determined in the discretion of the Committee or an individual (and, if applicable, Board) having the authority to approve the Participant's award pursuant to Section 5 below had such retirement, death, or transfer of employment not occurred.

3. Company Performance Goals. The CEOs will develop recommended Company performance goals. In consultation with the EIX CEO, the Committee will select specific performance goals for the Performance Year. The performance goals should represent relatively optimistic, but reasonably attainable goals, the accomplishment of which is intended to contribute significantly to the attainment of Company strategic objectives. In the event a Covered Officer provides services to a Company that is not such Covered Officer’s employer (the “Non-Employing Entity”), then the Committee may delegate to the EIX CEO the selection of specific performance goals of the Non-Employing Entity with respect to such Covered Officer but only to the extent that the Committee determines that such specific performance goals for such officer may be based on the performance of the Non-Employing Entity.

4. Individual Incentive Award Levels. Company, organizational and individual performance relative to the pre-established goals will determine the award a Participant can receive. The Committee, the CEO of a Company, or a designee, as permitted in accordance with the Committee Charter or other applicable controlling document, will establish target award levels for the Performance Year as a percentage of base salary at the time performance goals are set (and/or at such later time when the individual first becomes eligible to participate in the Plan or is eligible to receive a higher/lower target award level under the Plan because of a promotion/demotion or other approved reason). If a Participant is promoted after the Committee (or the EIX CEO, to the extent the selection of performance goals has been delegated to the EIX CEO) finalizes the performance goals for the Performance Year for purposes of Section 3 above (generally, the Committee meeting held in February each year) or otherwise becomes entitled to receive a higher/lower base salary and/or target award level under the Plan after such Committee action, that Participant’s incentive award for that Performance Year may be calculated based on the Participant's weighted average base salary and target award level, taking into account the base salary and target award level during the portion of the Performance Year preceding the promotion and/or change in base salary and/or target award level, and the base salary and target award level(s) during the remainder of such Performance Year. Notwithstanding any provisions in this Plan to the contrary, if a participant is on a disability leave for all or

	3

a portion of a Performance Year, any incentive award for the Participant for that Performance Year will (unless otherwise required by applicable law) be calculated by excluding the Participant’s base salary for the period(s) on such leave (for clarity, compensation pursuant to a disability plan or program is never taken into account for determining an award under this Plan). All awards are discretionary.

5. Approval and Payment of Individual Awards. During the first quarter of the year following the completion of the Performance Year, the EIX CEO, in consultation with the other CEOs, will assess the degree to which individual and corporate goals and objectives have been achieved. Incentive award recommendations for Participants will be developed. The Committee will receive a report from the EIX CEO as to Company performance, will deliberate on management recommendations, and will approve awards for Covered Officers. Awards to other Participants will be approved by the CEO of the respective Company, or a designee, as permitted in accordance with the Committee Charter or other applicable controlling document; provided, however, that if the selection of performance goals for a Company has been delegated to the EIX CEO, then the awards to officers of that Company who are not also officers of EIX or SCE will require the approval of the EIX CEO and the Board of the applicable Company. All decisions of the Committee, the EIX CEO, and the other CEOs regarding individual incentive awards will be final and conclusive (in the case of the EIX CEO and the other CEOs, as to awards for which the particular CEO has the authority to approve).

Incentive award payments will be made as soon as practical following the appropriate approval (and in all events within two and one-half months after the end of the Performance Year to which the award relates). Payment will be made in cash except to the extent an eligible Participant has previously elected to defer payment of some or all of the award pursuant to the terms of a deferred compensation plan of the Company. Award payments made will be subject to any income or payroll tax withholding or other deductions as may be required by Federal, State or local law. Any such payment shall be deemed an unearned advance, and, with respect to a Covered Participant, any such unearned advance shall be subject to recoupment pursuant to Section 15 of this Plan. Any incentive award amount deferred pursuant to the terms of a deferred compensation plan of the Company by a Covered Participant shall be subject to forfeiture pursuant to Section 15 of the Plan. By continuing to be employed by EIX, SCE, or one of their respective subsidiaries after the terms of this Plan have been communicated to a Covered Participant, such Covered Participant agrees and consents to the enforcement and implementation of the provisions set forth in Section 15 of the Plan without further consent or action being required of the Covered Participant, and the Covered Participant further agrees that none of the Companies (nor any of their respective subsidiaries) shall indemnify such Covered Participant against the loss of any amounts recouped pursuant to Section 15 of the Plan.

Awards under this Plan will not be considered to be salary or other compensation for the purpose of computing benefits to which the Participant may be entitled under any qualified Company retirement plan, including but not limited to the SCE Retirement Plan, the Edison 401(k) Savings Plan, or any other plan or arrangement of the Company for the benefit of its employees if such plan or arrangement is a plan qualified under Section 401(a) of the

	4

Code and is a trust exempt from Federal income tax under Section 501(a) of the Code. Awards may be considered compensation for nonqualified plan purposes depending on the terms and conditions of the particular nonqualified plan.

6. No Right to Assets. An award payable to a Participant under this Plan shall constitute an unsecured general obligation of the Participant’s employer (EIX or its affiliate, as the case may be, or, in the case of a former employee, the affiliate that last employed the Participant) (the applicable entity, the "Employer"), and no special fund or trust will be created, nor will any notes or securities be issued with respect to any awards. Participants will be no more than unsecured general creditors of the Employer with no special or prior right to any assets of the Employer for payment of any obligations hereunder. No Participant (or beneficiary of a Participant) will have a claim to benefits from any other affiliate. EIX is not a guarantor of the benefit obligations of other participating affiliates. By participating in, and by accepting any benefits under, this Plan, Participants consent to EIX sponsorship of this Plan, but acknowledge that EIX is not a guarantor of the benefit obligations of other participating affiliates. Each affiliate is responsible for payment of the accrued benefits under this Plan with respect to its own employees subject to the terms and conditions set forth herein. Notwithstanding the foregoing or anything in the definition of “Employer” to the contrary, and at the sole discretion of EIX, EIX may determine that for purposes of benefits payable under this Plan, EIX shall be deemed to be the Employer obligated to pay such benefits. Such an election by EIX may be made, in EIX’s sole discretion, as to all Plan benefits, as to only certain benefits, and/or as to only certain affiliates or Participants, and will be deemed an assumption of the specified benefit obligations of the applicable affiliates. Subject to the further provisions hereof, EIX will be solely obligated to pay any such benefits and no Participant (or beneficiary) will have a claim as to any other affiliate with respect to such benefits. Upon an election by EIX under this Section 6, benefits covered by the election will be paid from the general funds of EIX (and not the affiliate that would otherwise pay the benefits), provided that EIX may require that as between EIX and the affiliate that would otherwise pay such benefits, the affiliate will be responsible to pay EIX for the assumption of such obligations in accordance with funding arrangements determined by EIX at the time of election or any time thereafter. To the extent such affiliate fails to comply with such funding arrangements or obtains any refund or offset of payments made from the affiliate to EIX without the consent of EIX, the affiliate that would otherwise be responsible for payment of benefits to the applicable Participant will remain responsible for such benefits. EIX will effectuate any such election pursuant to this Section 6 by providing written notice to the Committee and the applicable affiliates regarding the effective date of such election, and the benefits, affiliates and Participants for which the election is applicable. The funding arrangements established by EIX at the time of its election, or from time to time thereafter, will set forth the method by which the affiliates will remit funds to EIX in consideration of benefit obligations that are assumed by EIX.

7. Plan Modifications and Adjustments. In order to ensure the incentive features of the Plan, avoid distortion in its operation and compensate for or reflect extraordinary changes which may have occurred during the Performance Year, the Committee may make adjustments to the Company performance goals or results or other Plan terms and

	5

conditions before, during or after the end of the Performance Year to the extent it determines appropriate in its sole discretion. If, pursuant to Section 3 above, the Committee has delegated the selection of performance goals for a Company to the EIX CEO, then this Section 7 authorizes the EIX CEO to make adjustments to that Company’s performance goals or results at any time in his or her sole discretion. Adjustments to performance goals, performance results, and other Plan terms and conditions made pursuant to the preceding provisions of this Section 7 shall be conclusive and binding upon all parties concerned. The Plan may be modified or terminated by the Committee at any time.

8. Plan Administration. Except as otherwise provided in other Sections of this Plan, administration of the Plan is delegated to the senior officer of EIX responsible for Human Resources (and to the EIX director responsible for executive compensation (the “EIX EC Director”) if EIX does not have an officer responsible for Human Resources other than the EIX CEO) and designees acting under his/her (or the EIX EC Director’s) direction. Such officer is authorized (and the EIX EC Director is authorized) to approve ministerial amendments to the Plan, to interpret Plan provisions, and to approve changes as may be required by law or regulation. Any decision or determination under or with respect to the Plan, as well as any interpretation of the Plan, by any Board, Committee or CEO, or by the senior officer of EIX responsible for Human Resources (or the EIX EC Director), in each case within its, his or her authority under or with respect to the Plan, shall be conclusive and binding upon all parties concerned. No Company, Board, Committee or individual shall be liable to any person for any action taken or omitted in connection with the interpretation and administration of the Plan.

9. Successors and Assigns. This Plan shall be binding upon and inure to the benefit of the heirs, legal representatives, successors and assigns of the Company and Participant.

Notwithstanding the foregoing, any right to receive payment hereunder is hereby expressly declared to be personal, nonassignable and nontransferable, except by will, intestacy, or as otherwise required by law, and in the event of any attempted assignment, alienation or transfer of such rights contrary to the provisions hereof, the Company shall have no further liability for payments hereunder.

10. Beneficiaries. Any award approved following the death of a Participant will be made to the Participant's most recently designated beneficiary or beneficiaries under the 2007 Performance Incentive Plan (or any successor equity incentive plan) of the Company. If no beneficiary has been designated by the Participant, or if no beneficiary survives the Participant, or if a designated beneficiary should die after surviving the Participant but before the award has been paid, any award approved will be paid in a lump-sum payment to the Participant's estate as soon as practicable.

11. Capacity. If any person entitled to payments under this Plan is incapacitated and unable to use such payments in his or her own best interest, the Company may direct that payments (or any portion) be made to that person's legal guardian or conservator, or that person's spouse, as an alternative to the payment to the person unable to use the payments. Court-appointed guardianship or conservatorship may be required by the Company before

payment is made. The Company shall have no obligation to supervise the use of such payments.

12. No Right of Employment. Nothing contained herein shall be construed as conferring upon the Participant the right to continue in the employ of the Company as an officer or manager of the Company or in any other capacity.

13. Severability and Controlling Law. The various provisions of this Plan are severable in their entirety. Any determination of invalidity or unenforceability of any one provision will have no effect on the continuing force and effect of the remaining provisions. This Plan shall be governed by the laws of the State of California.

14. Section 409A. The Company’s intent is that any payments and benefits paid under this Plan be exempt from, or comply with, Section 409A of the Code so as to not result in any tax, penalty or interest thereunder. To the maximum extent permitted, this Plan will be interpreted and administered consistent with such intent.

**15. Recoupment.**Notwithstanding any provision of this Plan to the contrary, any award to a Covered Participant under this Plan, and any payment that may be made in respect of an award under this Plan to such Covered Participant, shall be subject to recoupment by the Company or forfeiture by such Covered Participant in the event that (a) such Covered Participant’s employment with EIX, SCE, and their respective subsidiaries is terminated by the Employer or if such Covered Participant is placed on unpaid leave by the Employer and (b) the applicable Recoupment Administrator determines that such termination or unpaid leave placement arose from such Covered Participant having engaged in Misconduct. In such circumstances, the applicable Recoupment Administrator shall determine the extent (if any) to which an award to the Covered Participant under this Plan and/or any payment that may be made to the Covered Participant in respect of an award under this Plan shall be forfeited or recouped. To the extent a payment made to the Covered Participant in respect of an award under this Plan is to be recouped, the Covered Participant shall promptly pay to the Company the amount of the required recoupment. In addition, any award under this Plan, and any payment that may be made in respect of an award under this Plan, shall also be subject to any recoupment, “clawback” or similar provisions of applicable law, as well as the EIX and SCE Incentive Compensation Recoupment Policy for Accounting Restatements, as in effect from time to time (such policy, the “Mandatory Recoupment Policy”), and any other recoupment or similar policies of the Company that may be in effect from time to time; provided, however, that any portion of an award or payment under this Plan that is recouped pursuant to the Mandatory Recoupment Policy or as required by applicable law shall not be subject to further recoupment or forfeiture under this Section 15 or any other recoupment, “clawback” or similar policies of the Company that may be in effect from time to time.
