FORWARD-LOOKING STATEMENTS

This prospectus supplement, prospectus and the documents they incorporate by reference contain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements reflect our current expectations and projections about future events based on our knowledge of present facts and circumstances and assumptions about future events and include any statements that do not directly relate to a historical or current fact. Other information distributed by us that is incorporated in this prospectus supplement or in the accompanying prospectus, or that refers to or incorporates this prospectus supplement or the accompanying prospectus, may also contain forward-looking statements. In this prospectus supplement, in the accompanying prospectus, and elsewhere, the words “expects,” “believes,” “anticipates,” “estimates,” “projects,” “intends,” “plans,” “probable,” “may,” “will,” “could,” “would,” “should,” and variations of such words and similar expressions, or discussions of strategy or plans, are intended to identify forward-looking statements. Such statements necessarily involve risks and uncertainties that could cause actual results to differ materially from those anticipated. Some of the risks, uncertainties and other important factors that could cause results to differ from those currently expected, or that otherwise could impact us and our subsidiaries, include, but are not limited to:

• the ability of SCE to recover its costs through regulated rates, including costs related to uninsured wildfire-related and mudslide-related liabilities and capital spending incurred prior to formal regulatory approval;

• our ability to obtain sufficient insurance at a reasonable cost, including insurance relating to SCE’s nuclear facilities and wildfire-related claims, and to recover the costs of such insurance or, in the event liabilities exceed insured amounts, the ability to recover uninsured losses from customers or other parties;

• risks associated with California Assembly Bill 1054, executed by the Governor of California on July 12, 2019 (“AB 1054”), effectively mitigating the significant risk faced by California investor-owned utilities related to liability for damages arising from catastrophic wildfires where utility facilities are a substantial cause, including the ability of SCE and San Diego Gas & Electric to raise the funds required to make initial contributions to the insurance fund under AB 1054, SCE’s ability to maintain a valid safety certification; SCE’s ability to recover uninsured wildfire-related costs from the wildfire fund established under AB 1054, and the interpretation of and actions under AB 1054 by the California Public Utilities Commission (“CPUC”);

S-1

• decisions and other actions by the CPUC, the Federal Energy Regulatory Commission, the Nuclear Regulatory Commission and other regulatory authorities, including decisions and actions related to determinations of authorized rates of return or return on equity, the SCE Grid Safety and Resiliency Program application, the recoverability of wildfire-related and mudslide-related costs, and delays in regulatory actions;

• our or SCE’s ability to borrow funds and access the bank and capital markets on reasonable terms;

• actions by credit rating agencies to downgrade our or SCE’s credit ratings or to place those ratings on negative watch or outlook;

• risks associated with the decommissioning of the San Onofre Nuclear Generating Station, including those related to public opposition, permitting, governmental approvals,on-site storage of spent nuclear fuel, delays, contractual disputes, and cost overruns;

• extreme weather-related incidents and other natural disasters (including earthquakes and events caused, or exacerbated, by climate change, such as wildfires), which could cause, among other things, public safety issues, property damage and operational issues;

• risks associated with cost allocation resulting in higher rates for utility bundled service customers because of possible customer bypass or departure for other electricity providers such as Community Choice Aggregators, which are cities, counties, and certain other public agencies with the authority to generate and/or purchase electricity for their local residents and businesses, and electric service providers;

• risks inherent in SCE’s transmission and distribution infrastructure investment program, including those related to project site identification, public opposition, environmental mitigation, construction, permitting, power curtailment costs (payments due under power contracts in the event there is insufficient transmission to enable acceptance of power delivery), changes in the transmission plans of the California Independent System Operator (“CAISO”), and governmental approvals;

• risks associated with the operation of transmission and distribution assets and power generating facilities, including public and employee safety issues, the risk of utility assets causing or contributing to wildfires, failure, availability, efficiency, and output of equipment and facilities, and availability and cost of spare parts;

• the physical security of our and SCE’s critical assets and personnel and the cybersecurity of our and SCE’s critical information technology systems for grid control, and business, employee and customer data;

• our ability to develop competitive businesses, manage new business risks, and recover and earn a return on our investment in newly developed or acquired businesses;

• changes in tax laws and regulations, at both the state and federal levels, or changes in the application of those laws, that could affect recorded deferred tax assets and liabilities and effective tax rate;

�� • changes in the fair value of investments and other assets;

• changes in interest rates and rates of inflation, including escalation rates (which may be adjusted by public utility regulators);

• governmental, statutory, regulatory, or administrative changes or initiatives affecting the electricity industry, including the market structure rules applicable to each market adopted by the North American Electric Reliability Corporation, CAISO, Western Electricity Counsel and similar regulatory bodies in adjoining regions, and changes in California’s environmental priorities that lessen the importance the state places on greenhouse gas reduction;

• the availability and creditworthiness of counterparties and the resulting effects on liquidity in the power and fuel markets and/ or the ability of counterparties to pay amounts owed in excess of collateral provided in support of their obligations;

S-2

• the cost and availability of labor, equipment and materials;

• the potential for penalties or disallowance fornon-compliance with applicable laws and regulations; and

• the cost of fuel for generating facilities and related transportation, which could be impacted by, among other things, disruption of natural gas storage facilities, to the extent not recovered through regulated rate cost escalation provisions or balancing accounts.

Additional information about risks and uncertainties that could cause results to differ from those currently expected or that otherwise could impact us, including more detail about the factors described above, is included in our Annual Report on Form10-K for the year ended December 31, 2018 and our Quarterly Reports onForm 10-Q and Current Reports on Form8-K filed subsequent to that date.

Recent Developments

2019 Wildfire Legislation

On July 12, 2019, AB 1054 was signed by the Governor of California and became effective immediately. The following summary of the wildfire legislation below is based on our interpretation of the legislation and is qualified in its entirety by, and should be read together with, AB 1054 and companion Assembly Bill 111.

AB 1054 establishes a wildfire fund to reimburse utilities for payment of third-party damage claims arising from certain wildfires that exceed, in aggregate in a calendar year, the greater of $1 billion or the utility’s insurance coverage. The wildfire fund will only be available for claims related to wildfires ignited after July 12, 2019 that are determined to have been caused by a utility by the responsible government investigatory agency.

The wildfire fund can take one of two forms, an insurance fund or a liquidity fund. SCE, Pacific Gas & Electric Company (“PG&E”) and San Diego Gas & Electric (“SDG&E”) have notified the CPUC of their commitment to the insurance fund. The insurance fund will be established if both SCE and SDG&E make their initial contributions to the fund by September 10, 2019. If either SCE or SDG&E fail to make their initial contributions by the required date, the insurance fund will not be established and the wildfire fund will be a liquidity fund.

If the insurance fund is established, the CPUC will be required to apply a new standard when assessing the prudency of a participating utility in connection with a request for recovery of wildfire costs and, if the utility has a valid safety certification, shareholder liability for disallowed wildfire costs will be subject to a cap for as long as the fund is in existence. This liability cap is a cap on the aggregate requirement to reimburse the insurance

S-4

fund over a trailing three calendar year period equal to 20% of the equity portion of the utility’s transmission and distribution rate base in the year of the prudency determination. A utility will not be eligible for the liability cap if it does not maintain a valid safety certification or its actions or inactions that resulted in the wildfire are found to constitute conscious or willful disregard of the rights and safety of others. Further, under AB 1054, SCE is required to make certain capital investments without a return on equity, is required to file a wildfire mitigation plan every three years beginning in 2020, and can obtain an annual safety certification upon the submission of certain required safety information, including an approved wildfire mitigation plan. On July 25, 2019, SCE obtained its initial safety certification that will be valid for twelve months.

Under AB 1054, approximately $1.6 billion spent by SCE on wildfire risk mitigation capital expenditures cannot be included in the equity portion of SCE’s rate base. SCE can apply for an irrevocable order from the CPUC to finance these capital expenditures, including through the issuance of securitized bonds, and can recover any prudently incurred financing costs. SCE expects to finance this capital requirement by issuing securitized bonds.

Insurance Fund

The insurance fund, if it is established, is expected to be initially funded by $10.5 billion to be contributed by ratepayers and $7.5 billion in initial contributions from PG&E, SCE and SDG&E. PG&E’s participation in, and contributions to, the insurance fund is subject to it emerging from bankruptcy and meeting certain other conditions prior to June 30, 2020. If PG&E is unable to participate in the fund, the investor-owned utility initial contributions to the fund are expected to be approximately $2.7 billion. SCE, SDG&E and PG&E are also expected to make aggregate annual contributions of $3 billion to the insurance fund over a 10-year period. If PG&E is unable to participate in the fund, the investor-owned utility aggregate annual contributions to the fund are expected to be approximately $1 billion.

SCE has committed to make an initial contribution of approximately $2.4 billion by September 10, 2019, and ten annual contributions of approximately $95 million per year starting on January 1, 2020, to the insurance fund. We anticipate raising approximately $1.2 billion from this offering of our common stock and approximately $1.2 billion from the issuance of long-term debt at SCE in order to fund SCE’s contributions. SCE’s contributions to the insurance fund will not be recoverable through electric rates and will be excluded from the measurement of SCE’s CPUC-jurisdictional authorized capital structure. SCE will also not be entitled to cost recovery for any borrowing costs incurred in connection with its contributions to the insurance fund. We and SCE are currently evaluating the accounting impact of SCE’s anticipated contributions to the insurance fund, which may include a material charge to the earnings of Edison International and SCE that would not be greater than the total of SCE’s anticipated contributions to the insurance fund. SCE may, as a result of incurring a material charge, be temporarily unable to obtain financing through the issuance of first mortgage bonds, in which case SCE may be required to issue subordinated or unsecured debt and, as a result, could incur increased borrowing costs relative to first mortgage bonds.

RISK FACTORS

Investing in our common stock involves risk. You should be aware of and carefully consider the following risk factors and the risk factors included in our Annual Report on Form10-K for the year ended December 31, 2018 and our Quarterly Report on Form10-Q for the quarter ended June 30, 2019 (each of which is incorporated by reference in this prospectus supplement and the accompanying prospectus). New risks may emerge at any time, and we cannot predict such risks or estimate the extent to which they may affect our financial performance. You should also read and consider all of the other information provided or incorporated by reference in this prospectus supplement and the accompanying prospectus before deciding whether or not to purchase any of the offered shares of our common stock. See “Forward-Looking Statements” and “Where You Can Find More Information” in this prospectus supplement.

There may be future sales or other dilution of our equity, which may materially adversely affect the market price for shares of our common stock.

We are generally not restricted from issuing additional shares of our common stock, including any securities that are convertible into or exchangeable for, or that represent the right to receive, shares of our common stock or any substantially similar securities. The market price for shares of our common stock could materially decline as a result of sales of shares of common stock or similar securities in the market made after such offering or the perception that such sales could occur.

Although we have paid cash dividends on shares of our common stock in the past, we may not pay cash dividends or increase our dividends on shares of our common stock in the future.

Holders of shares of our common stock are entitled to receive only such dividends as our board of directors may declare out of funds legally available for such purpose. We have a history of paying dividends to our shareholders when sufficient cash is available. However, future cash dividends will depend on a number of factors including our cash requirements and the ability of our subsidiaries to pay dividends, make other distributions and repay funds owed from time to time to us. There can be no assurance that we will continue to pay dividends or increase our dividends even if the necessary financial conditions are met and if sufficient cash is available for distribution.

We may be unable to meet our ongoing and future financial obligations if our subsidiaries are unable to pay dividends to us.

Our ability to meet our financial obligations is primarily dependent on the earnings and cash flows of our subsidiaries and their ability to pay dividends, make other distributions or repay funds owed from time to time to us. Prior to funding Edison International, our subsidiaries have financial and regulatory obligations that must be satisfied, including, among others, debt service and preferred stock dividends. The CPUC also regulates SCE’s capital structure and limits the dividends it may pay to us.

S-7

USE OF PROCEEDS

The net proceeds we receive from this offering, after deducting the underwriting discounts and commissions and estimated expenses of $725,000 payable by us, are estimated to be $1.9 billion, or $2.2 billion if the underwriters exercise their option to purchase additional shares in full. The net proceeds we receive from the issuance and sale of the shares of our common stock will be used for general corporate purposes, including contributions to our subsidiary, SCE. Contributions to SCE will be used to repay commercial paper borrowings and for general corporate purposes, including a $1.2 billion contribution to the wildfire insurance fund to be established pursuant to AB 1054, as recently enacted by the California legislature and signed into law by the Governor of California.

As we have previously disclosed, in April 2019, we announced that we may issue up to $1.5 billion of shares of common stock, including through designated broker-dealers at prevailing market prices (anat-the-market offering). In July 2019, our board of directors approved the issuance of up to an additional $1.2 billion of shares of common stock through one or more underwritten offerings. Accordingly, in total, our board of directors has approved the issuance of up to $2.7 billion of shares of common stock, of which amount approximately $828 million, or $547 million if the underwriters exercise their option to purchase additional shares in full, will remain available after giving effect to the issuance of the common stock being offered hereby.

pursuant to clause (A) through (C), no filing by any party (donor, donee, transferor or transferee) under the Exchange Act or other public announcement is required or made voluntarily in connection with such transfer or distribution (other than a filing on a Form 5 made after the expiration of the 60 day period referred to above).

In connection with this offering, the underwriters may engage in stabilizing transactions, which involves making bids for, purchasing and selling shares of our common stock in the open market for the purpose of preventing or retarding a decline in the market price of the common stock while this offering is in progress. These stabilizing transactions may include making short sales of our common stock, which involves the sale by the underwriters of a greater number of shares of common stock than they are required to purchase in this offering, and purchasing shares of common stock on the open market to cover positions created by short sales. Short sales may be “covered” shorts, which are short positions in an amount not greater than the underwriters’ option to purchase additional shares referred to above, or may be “naked” shorts, which are short positions in excess of that amount. The underwriters may close out any covered short position either by exercising their option to purchase additional shares, in whole or in part, or by purchasing shares in the open market. In making this determination, the underwriters will consider, among other things, the price of shares available for purchase in the open market compared to the price at which the underwriters may purchase shares through the option to purchase additional shares. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the common stock in the open market that could adversely affect investors who purchase in this offering. To the extent that the underwriters create a naked short position, they will purchase shares in the open market to cover the position.

The underwriters have advised us that, pursuant to Regulation M of the Securities Act, they may also engage in other activities that stabilize, maintain or otherwise affect the price of the common stock, including the imposition of penalty bids. This means that if the Representatives purchase common stock in the open market in stabilizing transactions or to cover short sales, the Representatives can require the underwriters that sold those shares as part of this offering to repay the underwriting discount received by them.

These activities may have the effect of raising or maintaining the market price of the common stock or preventing or retarding a decline in the market price of the common stock, and, as a result, the price of the common stock may be higher than the price that otherwise might exist in the open market. If the underwriters commence these activities, they may discontinue them at any time. The underwriters may carry out these transactions on the New York Stock Exchange, in theover-the-counter market or otherwise.

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act of 1933, or to contribute to payments the underwriters may be required to make because of any of those liabilities.

Our common stock is listed on the NYSE under the symbol “EIX”.

Certain of the underwriters and their affiliates have performed investment banking, commercial banking and advisory services for us and our affiliates from time to time for which they have received customary fees and expenses. The underwriters and their affiliates may, from time to time, engage in transactions with and perform services for us and our affiliates in the ordinary course of their business.

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities.

In the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers, and such investment and securities activities may involve our securities and instruments or those of

As a result, the holders of our common stock and (if issued) preferred stock entitled to exercise more than 50% of the voting rights in an election of directors can elect all of the directors to be elected if they choose to do so. In such event, the holders of the remaining common stock and preferred stock voting for the election of directors will not be able to elect any persons to the board of directors.

Other Rights    

In the event of our liquidation, dissolution or winding up and after payment of all prior claims, holders of our common stock would be entitled to receive any of our remaining assets, subject to any preferential rights of holders of outstanding shares of preferred stock. Holders of our common stock have no preemptive rights to subscribe for additional shares of common stock or any of our other securities, nor do holders of our common stock have any redemption or conversion rights.

Listing

Our common stock is listed on the New York Stock Exchange under the symbol “EIX.”

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is Equiniti Trust Company.

PLAN OF DISTRIBUTION

We may sell the common stock registered pursuant to this prospectus in one or more of the following ways from time to time:

• to or through underwriters, dealers or agents;

• directly to agents or other purchasers;

• in “at the market offerings,” within the meaning of Rule 415(a)(4) of the Securities Act of 1933 (the “Securities Act”), to or through a market maker or into an existing trading market, on an exchange or otherwise;

• in forward contracts or similar arrangements;

• through a combination of any of the foregoing methods; or

• through any other method described in the applicable prospectus supplement.

We, directly or through agents or dealers, may sell, and any underwriters may resell, our common stock in one or more transactions:

• at a fixed price or prices, which may be changed;

• at market prices prevailing at the time of sale, including through transactions on the New York Stock Exchange or any other organized market where our common stock may be sold; or

• in negotiated transactions.

We will name any underwriter, dealer or agent involved in the offer and sale of common stock in the applicable prospectus supplement. In addition, we will describe in the applicable prospectus supplement the public offering or purchase price and the proceeds we will receive from the sale of our common stock, any compensation we will pay to underwriters, dealers or agents in connection with such offering of our common stock, any discounts, concessions or commissions allowed orre-allowed by underwriters to participating dealers, and any exchanges on which our common stock will be listed.

Dealers and agents participating in the distribution of our common stock may be deemed to be underwriters, and any discounts and commissions received by them and any profit realized by them on resale of the common stock may be deemed to be underwriting discounts and commissions. We may enter into agreements to indemnify underwriters, dealers and agents against certain civil liabilities, including liabilities under the Securities Act, and to reimburse these persons for certain expenses. We may also agree to contribute to payments that the underwriters, dealers or agents or any of their controlling persons may be required to make in respect of such liabilities. We may grant underwriters who participate in the distribution of the common stock we are registering pursuant to this prospectus an option to purchase additional shares in connection with a subsequent distribution. Certain underwriters, dealers or agents and their associates may engage in transactions with and perform services for us in the ordinary course of our business.

To facilitate a securities offering, certain persons participating in the offering may engage in sales in excess of the offering size, short covering transactions and penalty bids or stabilizing transactions in accordance with Regulation M under the Securities Exchange Act of 1934 (the “Exchange Act”). These activities, which may raise or maintain the market price of the common stock above independent market levels or prevent or retard a decline in the market price of the common stock include:

• sales in excess of the offering size that create a short position, which the persons participating in the offering may close out by exercising any option they receive to purchase additional shares of our common stock or by purchasing shares in the open market;

5

• stabilizing transactions that permit bids to purchase the underlying securities so long as the stabilizing bids do not exceed a specified maximum;

• short covering positions involving purchases of securities in the open market after the distribution is completed to cover short positions; and

• penalty bids permitting the underwriters to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a covering transaction to cover short positions.

The applicable prospectus supplement will describe any such activities. Should any of these activities be undertaken, they may be discontinued at any time.
