ABOUT THIS PROSPECTUS

This document consists of two parts. The first part is this prospectus supplement, which describes the specific terms of this offering. The second part is the accompanying prospectus, which describes more general information, some of which may not apply to this offering. This prospectus supplement and the accompanying prospectus are part of a registration statement that PG&E Corporation and Pacific Gas and Electric Company filed with the Securities and Exchange Commission (the “SEC”), utilizing a “shelf” registration process. When used in this prospectus supplement, (i) the terms “we,” “our,” “us” and “the Company” refer to Pacific Gas and Electric Company and its subsidiaries, and the term “Corp” refers to our parent, PG&E Corporation, and (ii) the “underwriters” refers to the firms listed on the cover page of this prospectus supplement. When we refer to the “Debtors” or “Reorganized Debtors” in this prospectus supplement, we refer to PG&E Corporation and Pacific Gas and Electric Company. Capitalized terms used in this prospectus supplement and not otherwise defined herein have the meanings given such terms in the Company’s and Corp’s Joint Annual Report on Form10-K for the year ended December 31, 2019, as amended (the “2019 Annual Report”), which is incorporated by reference into this prospectus supplement and the accompanying prospectus.

In connection with the Plan of Reorganization (as defined herein), the Company and Corp were required to prepare projected financial information to demonstrate to the Bankruptcy Court (as defined herein) the feasibility of the Plan of Reorganization and the ability of the Company and Corp to continue operations and satisfy their obligations under the Plan of Reorganization upon emergence from the Chapter 11 Cases (as defined herein). Neither those projections, which are attached as an exhibit to the Disclosure Statement (as defined herein) previously furnished to the SEC, nor any projections contained in any form of the Disclosure Statement previously furnished to the SEC, are incorporated in this prospectus supplement or should be considered or relied upon in connection with the purchase of the mortgage bonds offered hereby. Neither the projections nor any form of the Disclosure Statement were prepared for the purpose of any offering of the mortgage bonds and have not been, and may not be, updated on an ongoing basis. The projections reflect numerous assumptions concerning our anticipated future performance and prevailing and anticipated market and economic conditions at the time they were prepared that were and continue to be beyond our control and that may not materialize. Projections are inherently subject to uncertainties and to a wide variety of significant business, economic and competitive risks, including those risks discussed in the section titled “Risk Factors” in this prospectus supplement and in the section titled “Risk Factors” in Item 1A of Part I of the 2019 Annual Report and in Item 1A of Part II of our quarterly report on Form10-Q for the three months ended March 31, 2020 (the “Q1 Quarterly Report”) incorporated by reference herein. Our actual results will vary from those contemplated by the projections and the variations may be material. As a result, you should not rely upon the projections, the Disclosure Statement or any form of the Disclosure Statement previously furnished to the SEC in deciding whether to invest in the mortgage bonds.

As of December 31, 2019, approximatelytwo-thirds of our revenues were associated with owning and operating gas, electric and generation infrastructure. The remaining third were pass-through costs primarily associated with commodity procurement. We had approximately $86.15 billion in assets at March 31, 2020 and generated operating revenues of approximately $17.1 billion in 2019.

At December 31, 2019, we owned approximately 18,000 circuit miles of interconnected transmission lines operating at voltages ranging from 60 kilovolt (“kV”) to 500 kV. We also operated 33 electric transmission substations with a capacity of approximately 65,000 megavolt ampere (“MVA”). Our electric transmission system is interconnected with electric power systems in the Western Electricity Coordinating Council, which includes many western states, the Canadian provinces of Alberta and British Columbia, and parts of Mexico.

Our electric distribution network consists of approximately 107,000 circuit miles of distribution lines (of which, as of December 31, 2019, approximately 25% are underground and approximately 75% are overhead), 68 transmission switching substations, and 760 distribution substations, with a capacity of approximately 32,000 MVA.

At December 31, 2019, our natural gas system consisted of approximately 43,300 miles of distribution pipelines, over 6,300 miles of backbone and local transmission pipelines, and various storage facilities. We own and operate eight natural gas compressor stations on our backbone transmission system and one small station on our local transmission system that are used to move gas through our pipelines.

We are regulated primarily by the CPUC and the FERC. The CPUC has jurisdiction over the rates and terms and conditions of service for our electric and natural gas distribution operations, electric generation, and natural gas transmission and storage services. The CPUC also has exercised jurisdiction over our issuances of securities, dispositions of utility assets and facilities, energy purchases on behalf of our electric and natural gas retail customers, rates of return, rates of depreciation, oversight of nuclear decommissioning, and aspects of the siting of facilities used in providing electric and natural gas utility service. Our ability to recover revenue requirements authorized by the CPUC in these rate cases is independent, or “decoupled”, from the volume of our sales of electricity and natural gas services. As a result, our base revenues are not impacted by fluctuations in sales resulting from, for example, weather or economic conditions.

On December 19, 2019, the CPUC issued a final decision that authorized our capital structure and rates of return for our electric generation, electric and natural gas distribution, and natural gas transmission and storage rate base through 2023, consisting of 52% common equity, 47.5% long-term debt, and 0.5% preferred stock. The CPUC also set the authorized ROE through 2023 at 10.25% and reset the cost of debt to 5.16%. The CPUC also

S-8

authorized the continuation of an adjustment mechanism to allow our cost of debt and ROE to be adjusted if the utility bond index changes by certain thresholds, which are reviewed annually. In our cost of capital proceedings, we acknowledged that our cost of long-term debt for cost of capital purposes may be different than the approved cost upon our emergence from the Chapter 11 Cases. To account for this possible difference, we proposed to update our cost of debt for cost of capital purposes for the period beginning after our emergence from the Chapter 11 Cases to incorporate the costs of our exit financing, and the appropriate forward-looking forecast of debt costs for the remaining forecast period. The CPUC found our proposal to be reasonable and adopted it.

The FERC has jurisdiction over our electric transmission revenue requirements and rates, the licensing of substantially all of our hydroelectric generation facilities, and the interstate sale and transportation of natural gas. Under the formula rate mechanism, transmission revenue requirements will be updated to the actual cost of service annually as part of thetrue-up process.

In addition, the Nuclear Regulatory Commission (the “NRC”) oversees the licensing, construction, operation, and decommissioning of our nuclear generation facilities.

We provide natural gas transportation services to “core” customers (i.e., small commercial and residential customers) and to“non-core” customers (i.e., industrial, large commercial, and naturalgas-fired electric generation facilities) that are connected to our gas system in our service territory. Core customers can purchase natural gas procurement service (i.e., natural gas supply) from either us ornon-utility third-party gas procurement service providers (referred to as “core transport agents”). When core customers purchase gas supply from a core transport agent, we continue to provide gas delivery, metering and billing services to customers. When we provide both transportation and procurement services, we refer to the combined service as “bundled” natural gas service. Currently, more than 97% of core customers, representing approximately 82% of the annual core market demand, receive bundled natural gas service from us.

Concurrent Notes Offering

Concurrently with this offering, Corp is offering a combined $3.75 billion of its senior secured notes due 2025, senior secured notes due 2028 and senior secured notes due 2030 in the concurrent notes offering pursuant to a separate prospectus supplement. Corp expects to raise an aggregate of approximately $4.75 billion of gross proceeds in cash through (i) the issuance of the senior secured notes pursuant to the concurrent notes offering, and (ii) borrowings pursuant to a senior secured term loan facility that it expects to enter into. To the extent the amount of senior secured notes issued pursuant to the concurrent notes offering is more or less than $3.75 billion, the amount of borrowings pursuant to the senior secured term loan facility at the Effective Date would be reduced or increased, respectively by a corresponding amount. This prospectus supplement does not constitute an offer to sell, or the solicitation of an offer to buy, any securities being offered in the concurrent notes offering.

Corp expects to deposit the aggregate net proceeds of the concurrent notes offering, together with additional funds sufficient to fund a redemption of such senior secured notes on September 14, 2020 into a segregated escrow account. The escrow account and all amounts deposited therein will be pledged to secure the senior secured notes. Upon satisfaction of applicable escrow conditions, including the effectiveness of the Plan of Reorganization, Corp’s senior secured notes will be secured on a first-lien basis by the pledge of Corp’s ownership interest in 100% of the shares of our common stock.

S-9

The completion of this offering is not conditioned on the completion of the concurrent notes offering by Corp, and the completion of the concurrent notes offering is not conditioned on the completion of this offering. However, the release of the aggregate net proceeds of this offering and the concurrent notes offering from escrow are each conditioned upon the waiver or satisfaction of the applicable escrow conditions, which conditions include, among other things, the Debtors having obtained funding for the Reorganization.

Recent Developments

Approval of the Plan Financing Transactions

On June 11, 2020, the Bankruptcy Court entered an order authorizing Corp and the Company to enter into the Plan Financing Transactions (as defined below), including issuing the mortgage bonds offered hereby. A form of an order confirming the Plan of Reorganization was filed with the Bankruptcy Court on June 14, 2020 but has not yet been entered by the Bankruptcy Court. Following entry of an order confirming the Plan of Reorganization by the Bankruptcy Court (the “Confirmation Order”), the Debtors will emerge from the Chapter 11 Cases on the effective date of the Plan of Reorganization (the “Effective Date”). The Effective Date will not occur, and the Plan of Reorganization will not be consummated, unless and until the Confirmation Order has been entered and the conditions to the occurrence of the Effective Date provided in the Plan of Reorganization have been satisfied or duly waived pursuant to the terms of the Plan of Reorganization. There can be no assurance that the Effective Date will occur.

Plan Financing Transactions

As a condition to emergence and in order to effectuate the Reorganization, Corp expects to raise an aggregate of $9.0 billion of gross proceeds in cash through one or more equity financing transactions, and we and Corp expect to raise an aggregate of $16.675 billion of gross proceeds in cash through one or more debt offerings, including the mortgage bonds offered hereby, and one or more other debt financing transactions, including the entry into one or more credit facilities and/or term loans (collectively, the “Plan Financing Transactions”).

We and Corp expect to enter into the following financing transactions as part of the Plan Financing Transactions:

• Corp expects to raise an aggregate of approximately $9.0 billion of gross proceeds in cash through the PIPE Transaction (as defined below) and the issuance of common stock and/or other equity and/or equity-linked securities pursuant to one or more offerings and/or private placements;

• Corp expects to raise an aggregate of approximately $4.75 billion of gross proceeds in cash through (i) the issuance of senior secured notes pursuant to the concurrent notes offering, and (ii) borrowings pursuant to a senior secured term loan facility that it expects to enter into; and

• we expect to issue approximately $5.925 billion of mortgage bonds pursuant to this offering.

In the event that Corp raises less than $9.0 billion of gross proceeds from any offerings of equity and/or equity-linked securities, it expects to draw on the Equity Backstop Commitment Letters in order to raise additional equity capital up to an amount equal to such shortfall.

In addition to the foregoing, we and Corp expect to enter into the following financing transactions as part of the Plan Financing Transactions:

• Corp expects to enter into a revolving credit agreement consisting of a $500.0 million revolving credit facility (anticipated to be undrawn on the Effective Date);

S-10

• we expect to enter into a revolving credit agreement consisting of a $3.5 billion revolving credit facility (to the extent cash and cash equivalents as of the Effective Date are insufficient for the purpose of funding the uses described under the heading “Uses of Funds” under “Use of Proceeds”, we expect to draw on the revolving credit agreement; in addition, availability thereunder will be reduced by the amount of letters of credit that will be outstanding thereunder as of the Effective Date); and

• we expect to enter into a term loan credit agreement consisting of an up to $6.0 billion term loan credit facility. To the extent we raise more than $5.925 billion in this offering, the commitments under the term loan credit facility will be reduced by such amount.

Neither we nor Corp can provide any assurance that this offering or the other Plan Financing Transactions will be completed on the terms we or Corp anticipate, or at all. The terms and conditions of the Plan Financing Transactions described herein have not been finalized and are subject to change. Investors are encouraged not to place undue reliance on such descriptions in deciding to invest in the mortgage bonds offered hereby, as changes may be made after the date of this prospectus supplement.

The completion of this offering and any other Plan Financing Transactions are not conditioned upon one another. However, the release of the aggregate net proceeds of this offering from escrow is conditioned upon the waiver or satisfaction of the Escrow Conditions, which conditions include, among other things, the Debtors having obtained funding for the Reorganization. Similarly, the consummation, or the release from escrow of the aggregate net proceeds, of each of the other Plan Financing Transactions, is conditioned upon, among other things, the Effective Date, which in turn is conditioned upon the Debtors having obtained funding for the Reorganization.

See “Plan of Reorganization—Plan Financing Transactions” and “Description of Other Indebtedness and Preferred Stock” for more information.

Debt Backstop Commitment Letters

In connection with the Plan of Reorganization, on October 11, 2019, the Debtors entered into debt backstop commitment letters with certain commitment parties, which were subsequently amended on November 18, 2019, December 20, 2019, January 30, 2020, February 14, 2020 and February 28, 2020, and pursuant to which such commitment parties committed to provide $10.825 billion in bridge financing in the form of (i) a $5.825 billion senior secured bridge loan facility with the Company or any domestic entity formed to hold all of the assets of the Company upon emergence from the Chapter 11 Cases as borrower thereunder (the “Utility Bridge Facility”) and (ii) a $5.0 billion senior unsecured bridge loan facility with Corp or any domestic entity formed to hold all of the assets of Corp upon emergence from the Chapter 11 Cases as borrower thereunder (the “HoldCo Bridge Facility”, and together with the Utility Bridge Facility, the “Bridge Facilities”), subject to the terms and conditions set forth therein. The commitments under the debt backstop commitment letters will expire on August 29, 2020, unless terminated earlier pursuant to the termination rights described below.

In lieu of entering into the facilities provided for in the debt backstop commitment letters, the Debtors intend to obtain permanent financing on or prior to the Effective Date pursuant to the Plan Financing Transactions. The financing commitments under the Utility Bridge Facility will be reduced by the aggregate gross proceeds of the mortgage bonds offered hereby, and the financing commitments under the HoldCo Bridge Facility will be reduced by the gross proceeds of the senior secured notes offered in the concurrent notes offering and the New HoldCo Term Loan Credit Agreement.

See “Plan of Reorganization—Debt Backstop Commitment Letters” for more information.

PIPE Transaction

On June 7, 2020, Corp entered into an Investment Agreement (the “Investment Agreement”) with affiliates of Appaloosa, LP, Third Point LLC, Zimmer Partners, LP, Fidelity Management & Research Company, LLC and GIC Pte Ltd (each, a “PIPE Investor” and together, the “PIPE Investors”), relating to the issuance and sale to the PIPE Investors of an aggregate of $3.25 billion of Corp’s common stock at a price per share to be determined based on a discount to the public offering price of common stock (or rights to purchase such stock, if applicable) in certain public equity offerings, as described and subject to the terms and conditions contained in the Investment Agreement. Issuance of common stock and consummation of the other transactions contemplated by the Investment Agreement (collectively, the “PIPE Transaction”) is conditioned upon, among other things, consummation by Corp of at least $5.75 billion of gross proceeds of sales of common stock or other equity securities in respect of common stock other than pursuant to the Investment Agreement (of which at least $2.5 billion must be an underwritten offering of common stock). In addition, each PIPE Investor will have the right to terminate the Investment Agreement solely as to itself if Corp notifies one or more Backstop Parties that the Backstop Parties will be required to purchase shares of common stock as described in Section 2(a) of their respective Equity Backstop Commitment Letters, or if the closing of the transactions contemplated by the Investment Agreement has not taken place on or prior to the 45th day following the date of the Investment Agreement. Closing of the PIPE Transaction is expected to occur on the Effective Date. Corp expects that the issuance and sale of common stock to the PIPE Investors will provide a portion of the $9.0 billion of gross proceeds it expects to raise through equity financing in connection with the Plan Financing Transactions.

The foregoing description of the terms of the Investment Agreement and the transactions contemplated thereby does not purport to be complete and is subject, and qualified in entirety by reference, to the full text of the Investment Agreement and the schedules thereto, which is included as Exhibit 10.4 to Corp’s and the Company’s Current Report on Form8-K filed with the SEC on June 8, 2020.

Funding of Fire Victim Trust

In full satisfaction, release and discharge of the wildfire-related claims of certain individuals, public entities and other claimants (the “Fire Victim Claims”), on the Effective Date, we and Corp will fund the Fire Victim Trust (as defined below under “Plan of Reorganization”) with aggregate consideration consisting of $6.75 billion in cash (including $1.35 billion on a deferred basis), common stock of reorganized PG&E Corporation representing 22.19% of the outstanding common stock of reorganized PG&E Corporation as of the Effective Date, subject to potential adjustments, (plus certain other rights), in each case in accordance with the terms of the Plan of Reorganization.

Ranking and Security The mortgage bonds will be our senior obligations and will rank equally in right of payment with our other existing or future first mortgage bonds issued under the Mortgage Indenture. After giving effect to the Reorganization (including the Plan Financing Transactions), approximately $27,348 million of first mortgage bonds (including the mortgage bonds offered hereby), and approximately $6,000 million of additional first mortgage bonds issued to provide security for obligations under the New Utility Term Loan Credit Agreement, will be issued and outstanding under the indenture that will govern the mortgage bonds and as of the Effective Date, all of which rank pari passu with the mortgage bonds. In addition, we would have had approximately $3.5 billion of availability to incur additional indebtedness under the New Utility Revolving Credit Agreement, all of which would be secured by additional first mortgage bonds issued under the same indenture as the mortgage bonds.

Upon release of the proceeds of this offering from escrow, the mortgage bonds will be secured by a first lien, subject to Permitted Liens (as defined herein), on substantially all of our real property and certain tangible personal property related to our facilities.

See “Use of Proceeds” for a description of the estimated sources and uses of funds relating to the financing transactions that we expect to consummate in connection with our reorganization.

Escrow of Net Proceeds; Special Mandatory Redemption If the Escrow Conditions (as defined under the caption “ Description of the Mortgage Bonds—Escrow of Net Proceeds; Special Mandatory Redemption ”) are not satisfied prior to the consummation of this offering, we will deposit the aggregate net proceeds of this offering, together with additional funds, which together with such net proceeds

S-14

would be sufficient to fund a redemption of all the mortgage bonds on September 14, 2020, into a segregated escrow account. The escrow account and all amounts deposited therein will be pledged to secure the mortgage bonds. Until the Escrow Conditions are satisfied, the mortgage bonds will be secured by a lien on amounts deposited in the Escrow Account. If the Escrow Conditions are not satisfied on or prior to September 9, 2020 (or, if prior to such date, we determine in our sole discretion that any of the Escrow Conditions cannot be satisfied by such date), the mortgage bonds will be subject to a special mandatory redemption at a redemption price of 101% of the principal amount of the mortgage bonds offered hereby, plus accrued and unpaid interest to, but not including, the redemption date. See “Description of the Mortgage Bonds—Escrow of Net Proceeds; Special Mandatory Redemption.”

Optional Redemption After the satisfaction of the Escrow Conditions, we may redeem each series of mortgage bonds at any time prior to maturity, in whole or in part, at our option, at the redemption prices described under “Description of the Mortgage Bonds—Optional Redemption.”

Additional Mortgage Bonds We may issue additional first mortgage bonds under the Mortgage Indenture (as defined herein) only in amounts not exceeding 70% of the net amount of property additions or in amounts equal to the aggregate principal amount of previously issued first mortgage bonds being canceled. See “Description of the Mortgage Bonds—Issuance of Additional First Mortgage Bonds.”

Certain Covenants The Mortgage Indenture that will govern the mortgage bonds will contain certain covenants limiting our ability to, among other things:

• merge or consolidate with another entity; and

• convey, lease or otherwise transfer all or substantially all of our assets.

These covenants are subject to the qualifications and exceptions described under “Description of the Mortgage Bonds—Consolidation, Merger and Transfer of Mortgaged Property.”

Investors may elect to hold the interests in the global notes through any of DTC, Clearstream Banking, S.A. or Euroclear Bank SA/NV, as described under the heading “Description of the Mortgage Bonds—Book-Entry Issuance; Global Securities”.

Mortgage Trustee The Bank of New York Mellon Trust Company, N.A., as trustee (the “Mortgage Trustee”).

Rate Base Data

The following table sets forth the Company’s historical aggregate rate base for the periods indicated. The Company’s rate base represents the amount of funds provided by investors that the Company’s regulators determine are prudently invested in the Company’s assets. Rate base is calculated as the total value of the assets invested by the Company, less accumulated depreciation and net deferred taxes, and may include certain other additions or deductions. The Company’s regulators use rate base to determine, in periodic proceedings, the amount of revenue requirements that the Company is authorized to collect from customers to recover its anticipated costs related to its electric distribution, natural gas distribution, electric transmission, natural gas transmission, and Company-owned electric generation operations and to provide the Company an opportunity to earn its authorized rate of return. The Company’s historical rate base is not necessarily indicative of the rate base to be expected for future periods. For more information, you should read the related disclosure under the sections titled “Regulatory Environment,” “Ratemaking Mechanisms,” “Rate Cases” and “Transmission Owner Rate Cases” of the 2019 Annual Report (and corresponding updates in the Q1 Quarterly Report) incorporated by reference in this prospectus supplement.

Non-GAAP Measures

Corp discloses certain financial measures that are not prepared in accordance with GAAP, including“Non-GAAP Core Earnings” and “Adjusted EBITDA.” BecauseNon-GAAP Core Earnings and Adjusted EBITDA are not measurements determined in accordance with GAAP and are susceptible to varying calculations, such measures may not be comparable to other similarly titled measures presented by other companies.Non-GAAP Core Earnings and Adjusted EBITDA are not substitutes or alternatives for measures prepared in accordance with GAAP such as net income and income available for common shareholders.

S-18

Non-GAAP Core Earnings

Non-GAAP Core Earnings is calculated as income available for common shareholders lessnon-core items.“Non-core items” include items that the management of Corp and the Company do not consider representative of ongoing earnings and affect comparability of financial results between periods. Corp and the Company useNon-GAAP Core Earnings to understand and compare operating results across reporting periods for various purposes including internal budgeting and forecasting, short-and long-term operating planning, and employee incentive compensation. Corp and the Company believe thatNon-GAAP Core Earnings provide additional insight into the underlying trends of the business, allowing for a better comparison against historical results and expectations for future performance. Corp disclosesNon-GAAP Core Earnings in order to provide a measure that allows investors to compare the underlying financial performance of the business from one period to another, exclusive of items impacting comparability.

Beginning with the quarter and full year periods ended December 31, 2019, Corp and the Company changed the name of their principalnon-GAAP earnings metric from“Non-GAAP Earnings from Operations” to “Non-GAAP Core Earnings” in order to align more closely with the terminology used by their industry peers. Likewise, Corp and the Company will now refer to adjustments as“non-core items” rather than “items impacting comparability.”

The following table sets forthNon-GAAP Core Earnings, as well as a reconciliation ofNon-GAAP Core Earnings to Income (Loss) Available to Common Shareholders of Corp, the most directly comparable GAAP financial measure, for the periods indicated. All amounts presented in the table below are tax adjusted at Corp’s statutory tax rate of 27.98% for 2018 and 2019, and 40.75% for 2017, except for certain Wildfire-related, Chapter11-related, 2019 GT&S capital disallowance costs and fines, which are not tax deductible. Amounts may not sum due to rounding.

Notes:

(1) The Company incurred costs of $12.2 billion (before the tax impact of $3.4 billion), $12.4 billion (before the tax impact of $3.5 billion) and $142 million (before the tax impact of $57 million), during the years ended December 31, 2019, 2018 and 2017, respectively, associated with wildfire-related costs related to the 2018 Camp fire, the 2017 Northern California wildfires, and the 2015 Butte fire. This includes accrued charges

S-19

related to increases in the recorded liability for third-party claims of $11.4 billion (before the tax impact of $3.2 billion), $14.0 billion (before the tax impact of $3.9 billion) and $350 million (before the tax impact of $143 million), during the years ended December 31, 2019, 2018 and 2017, respectively. In addition, the Company incurredclean-up and repair costs of $278 million (before the tax impact of $78 million) and $209 million (before the tax impact of $58 million) during the years ended December 31, 2019 and 2018, respectively. The Company also incurred legal and other costs of $152 million (before the tax impact of $43 million), $245 million (before the tax impact of $68 million) and $78 million (before the tax impact of $32 million), during the years ended December 31, 2019, 2018 and 2017, respectively.

Further, the Company incurred costs of $398 million (before the tax impact of $108 million) during the year ended December 31, 2019 related to the Wildfire OII settlement. The Company also recorded a charge of $86 million (before the tax impact of $24 million) during the year ended December 31, 2019 related to aone-time bill credit for customers impacted by the October 9, 2019 Public Safety Power Shutoff (PSPS) event. The Company also recorded $185 million (before the tax impact of $52 million) and $64 million (before the tax impact of $26 million) during the years ended December 31, 2018 and 2017, respectively, reflecting the accelerated amortization of prepaid insurance premiums for single event coverage policies.

These costs were partially offset by $189 million (before the tax impact of $53 million) recorded during the year ended December 31, 2019 for probable cost recoveries of insurance premiums incurred in 2018 above amounts included in authorized revenue requirements and $32 million (before tax impact of $9 million) for probable cost recoveries of insurance premiums incurred in 2017 above amounts included in authorized revenue requirements. These costs were also offset by $2.2 billion (before the tax impact of $624 million) and $350 million (before the tax impact of $143 million) recorded during the years ended December 31, 2018 and 2017, respectively, for probable insurance recoveries.

(2) The Company incurred costs of $46 million (before the tax impact of $13 million) and $89 million (before the tax impact of $37 million) during the years ended December 31, 2018 and 2017, respectively, for pipeline-related expenses incurred in connection with the multi-year effort to identify and remove encroachments from transmission pipelinerights-of-way.

(3) The Company recorded costs of $237 million (before the tax impact of $44 million) during the year ended December 31, 2019 for pipeline-replacement costs disallowed in the 2019 GT&S rate case as a result of spending above amounts authorized in the 2015-2018 rate case period. Due to flow-through treatment related to deductible repairs, $80 million of the loss does not generate a net tax benefit.

(4) The Company incurred costs of $773 million (before the tax impact of $216 million) during the year ended December 31, 2019 for incremental operating expenses related to enhanced and accelerated inspections of electric transmission and distribution assets, and resulting repairs that are not probable of recovery.

(5) The Company recorded costs of $39 million (not tax deductible) during the year ended December 31, 2019 associated with an incremental fine payable to the State General Fund resulting from a presiding officer’s decision in the Locate and Mark OII.

(6) Corp and the Company incurred costs of $199 million (before the tax impact of $19 million) during the year ended December 31, 2019 directly associated with their Chapter 11 Cases. This includes legal and other costs of $292 million (before the tax impact of $45 million) during the year ended December 31, 2019. The Company also incurred $114 million (before the tax impact of $32 million) during the year ended December 31, 2019 for DIP financing costs. These costs were partially offset by a reduction to interest expense onpre-petition debt of $146 million (before the tax impact of $41 million) during the year ended December 31, 2019, and interest income of $60 million (before the tax impact of $17 million) recorded during the year ended December 31, 2019.

(7) The Company reduced the estimated disallowance forgas-related capital costs that were expected to exceed authorized amounts by $38 million (before the tax impact of $11 million) during the year ended December 31, 2018. The Company had previously recorded $85 million (before the tax impact of $35 million) in 2016 for probable capital disallowances in the 2015 GT&S rate case. From 2012 through 2014,

S-20

the Company had recorded cumulative charges of $665 million (before the tax impact of $271 million) for disallowed Pipeline Safety Enhancement Plan-related capital expenditures.

(8) Corp, on a consolidated basis, incurred aone-time charge of $147 million during the three and year ended December 31, 2017, as a result of the Tax Cuts and Jobs Act, which was signed into law on December 22, 2017. The Company’s charge of $64 million was related to deferred tax assets not reflected in authorized revenue requirements, such as deferred tax assets associated with disallowed plant, and Corp’s charge of $83 million was primarily related to net operating loss carryforwards and compensation-related deferred tax assets.

(9) The Company incurred costs of $71 million (before the tax impact of $24 million) during the year ended December 31, 2017, for fines and penalties. This includes costs of $32 million (before the tax impact of $13 million) during the year ended December 31, 2017, associated with safety-related cost disallowances imposed by the CPUC in its April 9, 2015 San Bruno Penalty Decision in the gas transmission pipeline investigations. The Company also recorded $15 million (before the tax impact of $6 million) during the year ended December 31, 2017, for penalty imposed by the CPUC in its final phase two decision of the 2015 Gas Transmission and Storage (“GT&S”) rate case for prohibited ex parte communications. In addition, the Company recorded $24 million (before the tax impact of $5 million) during the year ended December 31, 2017, in connection with the proposed decision in the OII into Compliance with Ex Parte Communication Rules.

(10) Consistent with the CPUC decision adopted on January 11, 2018 in connection with the retirement of the Diablo Canyon Power Plant, the Company recorded a disallowance of $47 million (before the tax impact of $15 million) during the year ended December 31, 2017, comprised of cancelled projects of $24 million (before the tax impact of $6 million) and disallowed license renewal costs of $23 million (before the tax impact of $9 million).

(11) As a result of the CPUC’s final phase two decision in the 2015 GT&S rate case, during the year ended December 31, 2017, the Company recorded revenues of $150 million (before the tax impact of $62 million) in excess of the 2017 authorized revenue requirement, which includes the final component of under-collected revenues retroactive to January 1, 2015.

(12) Corp recorded proceeds from insurance, net of plaintiff payments, of $65 million (before the tax impact of $27 million) during the year ended December 31, 2017, associated with the settlement agreement in connection with the shareholder derivative litigation that was approved by the court on July 18, 2017. This includes $90 million (before the tax impact of $37 million) for insurance recoveries partially offset by $25 million (before the tax impact of $10 million) for plaintiff legal fees paid in connection with the settlement during the year ended December 31, 2017.

Adjusted EBITDA

Adjusted EBITDA is calculated as net income (loss) plus income tax provision (or less income tax benefit); less other income, net; plus interest expense; less interest income; plus reorganization items, net; plus depreciation, amortization, and decommissioning; plus wildfire-related costs; plus electric asset inspection costs; and plus San Bruno penalty decision. Corp discloses Adjusted EBITDA in order to provide a measure that investors may find useful for evaluating Corp’s performance during the pendency of the Chapter 11 Cases. Corp’s management generally does not use Adjusted EBITDA in managing its business.

RISK FACTORS

Investing in the mortgage bonds involves risk. These risks are described below and in the section titled “Risk Factors” in Item 1A of Part I of the 2019 Annual Report and in Item 1A of Part II of the Q1 Quarterly Report. See the section titled “Where You Can Find More Information.” Before making a decision to invest in the mortgage bonds, you should carefully consider these risks, as well as other information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus.

Risks Relating to our Business

Corp’s and the Company’s financial condition, results of operations, liquidity and cash flows could be significantly affected by the outbreak of theCOVID-19 pandemic.

Corp’s and the Company’s financial condition, results of operations, liquidity and cash flows have been (beginning in March 2020) and will continue to be significantly affected by the outbreak ofCOVID-19. In December 2019, a novel strain of coronavirus(COVID-19) was reported to have surfaced in Wuhan, China, resulting in significant disruptions to manufacturing, supply chain, markets, and travel world-wide. On January 30, 2020, the International Health Regulations Emergency Committee of the World Health Organization declared theCOVID-19 outbreak a public health emergency of international concern and on March 12, 2020, announced the outbreak was a pandemic. On March 16, 2020, the CPUC directed electric utility companies to follow customer protection measures including a moratorium on service disconnections, retroactive to March 4, 2020. On March 19, 2020, the California Governor institutedshelter-in-place measures that became effective state-wide on March 19, 2020. On April 28, 2020, the California Governor announced four different stages for easing the Californiashelter-in-place measures. On May 4, 2020, the California Governor issued an executive order directing the State Public Health Officer to establish criteria to determine whether and how local health officers may implement less restrictive measures, and on May 7, 2020, the State Public Health Officer issued an order, effective May 8, 2020, directing local health officers to begin gradual movement into Stage 2 of the Pandemic Resilience Roadmap for the State of California in which theshelter-in-place measures are modified to allow certainlow-risk businesses and other spaces tore-open. It is uncertain when further modifications to theshelter-in-place measures will be implemented. While the extent of the impact of the currentCOVID-19 coronavirus outbreak on Corp and the Company’s business and financial results is uncertain, the consequences of a continued and prolonged outbreak and resulting government and regulatory orders could have a further negative impact on the Company’s financial condition, results of operations, liquidity and cash flows.

The outbreak ofCOVID-19 and the resulting economic conditions, including but not limited to the shelterin-place order and resulting decrease in economic and industrial activity in the Company’s service territory have and will continue to have a significant adverse impact on the Company’s customers and, as a result, these circumstances impact and will continue to impact the Company for a period of time that Corp and the Company are unable to predict. For example, the economic downturn has already resulted in a reduction in customer receipts and collection delays for March, April and May 2020.

The Company’s customer energy accounts receivable balances over 30 days outstanding as of March 31, 2020 were approximately $421 million, subsequently increased to $438 million as of April 30, 2020, and further increased to $489 million as of May 31, 2020, or $33 million, $84 million and $145 million higher, respectively, as compared to the corresponding months in 2019. The Company is unable to estimate the portion of the increase directly attributable to theCOVID-19 pandemic. The Company expects to continue experiencing an impact on monthly cash collections in 2020 and for as long as currentCOVID-19 circumstances persist.

On April 16, 2020 the CPUC passed a resolution ratifying the customer protection measures from the March 16, 2020 order and allowing associated costs to be tracked in a memorandum account. In addition, the Company’s proposed 2020 GRC settlement would continue the Company’s existing mechanism to address uncollectibles, which allows the Company to readjust its uncollectibles rate on an annual basis based on the most-recent10-year average of uncollectibles. The Company is unable to predict whether these measures will allow for future recovery of these amounts.

S-23

In addition, the Company has experienced average reductions of approximately 3% in electric load and approximately 4% in core gas load on a weather-adjusted basis frommid-March tolate-May, resulting in an estimated $45 million to $70 million monthly reduction in billed revenues.

Corp and the Company are currently unable to quantify the potential long-term impact of the changes in customer collections or changes in energy demand on earnings and cash flows, due, in part, to uncertainties regarding the timing, duration and intensity of theCOVID-19 outbreak and the resulting economic downturn. Although the CPUC authorized the establishment of memorandum accounts to track costs associated with customer protection measures, the timing of regulatory relief, if any, and ultimately cost recovery from such memorandum accounts or otherwise, are uncertain.

TheCOVID-19 pandemic and resulting economic downturn have resulted and will continue to result in workforce disruptions, both in personnel availability (including a reduction in contract labor resources) and deployment. Although the Company continues to prioritize customer and community safety, these disruptions necessitate changes to the Company’s operating and capital expenditure plans, which could lead to project delays or service disruptions in certain programs. Delays in production and shipping of materials used in the Company’s operations may also impact operations. In addition,COVID-19 has the potential to cause delays and disruptions in various regulatory proceedings in which the Company is involved. Following Department of Health guidance concerning restrictions on public gatherings, the CPUC has cancelled all public forums and has been conducting remote meetings for events it deems essential. A disruption in CPUC operations could impact the timing of Corp’s and the Company’s rate cases and other regulatory proceedings.

In addition, a group of local government entities and organizations filed a Joint Motion asking the CPUC to require utilities to comply with additional requirements when implementing PSPS events while local areas aresheltering-in-place due toCOVID-19. A CPUC decision could restrict or impose additional requirements on the Company in implementing PSPS events.

Corp and the Company expect additional financial impacts in the future as a result ofCOVID-19. Potential longer term impacts ofCOVID-19 on Corp or the Company include the potential for higher borrowing costs due to the increasing difference in the higher yield of lower-rated debt as compared to the lower yield of higher-rated debt of similar maturity and incremental financing needs. Corp and the Company’s analysis of the potential impact ofCOVID-19 is preliminary and subject to change. Corp and the Company are unable to predict the timing, duration or intensity of theCOVID-19 situation and its effects on the business and general economic conditions in the State of California and the United States of America. Corp and the Company continue to monitor and assess the impact of theCOVID-19 pandemic.

Market conditions resulting from the outbreak ofCOVID-19 may hinder Corp’s and the Company’s exit financing to emerge from Chapter 11.

The outbreak ofCOVID-19 and the resulting economic downturn have adversely affected the financial markets and the economy more generally and could result in an economic downturn. As of March 31, 2020, the S&P 500 had declined over 20% from its previous high close recorded on February 19, 2020, and while there has subsequently been some recovery in the financial markets, the economic outlook remains uncertain. Corp and the Company are relying on the equity and debt capital markets in order to finance their emergence from Chapter 11. Although Corp’s expected equity raise for approximately $9.0 billion of gross proceeds is backstopped by the Equity Backstop Commitment Letters, obtaining financing from the capital markets at higherprice-to-earnings multiples than the multiple contemplated by the Equity Backstop Commitment Letters would result in significantly less dilution to shareholders. In addition, it is possible that the commitments under the Equity Backstop Commitment Letters are not available due to potential termination events or a default by one or more backstop parties. Corp’s and the Company’s debt financing, as contemplated by the Plan of Reorganization, are supported by the Debt Backstop Commitment Letters (as defined herein) and the Company TL Commitment Letter in an aggregate amount of $16.8 billion, although it is possible that Corp and the Company fail to satisfy

S-24

the conditions set forth in these letters. In any event, adverse capital market conditions related toCOVID-19 (or otherwise) could make it more difficult or expensive, or even infeasible, to emerge from Chapter 11 through the use of one or more capital market financing transactions.

Risks Relating to the Reorganization and our Indebtedness

The Company’s substantial indebtedness following the Reorganization, a large percentage of which will be secured, may adversely affect our financial health and operating flexibility.

We will have a substantial amount of indebtedness following the Reorganization. As of March 31, 2020 on an as adjusted basis after giving effect to the Reorganization (including the Plan Financing Transactions and the amounts of Indebtedness that we anticipate incurring pursuant thereto) as if such transactions occurred on March 31), we would have had approximately $33.3 billion of total indebtedness outstanding. All of our outstanding indebtedness, including the mortgage bonds hereby, will be secured by substantially all of our real property and certain tangible personal property related to our facilities. In addition, Corp will have approximately $4.75 billion of additional indebtedness outstanding. Because we are Corp’s primary subsidiary, we expect that Corp will look to dividends from us to satisfy its debt obligations. See “Capitalization” for more information.

Since we have such a high level of debt, a substantial portion of cash flow from operations will be used to make payments on this debt. Furthermore, since a significant percentage of our assets are used to secure this debt, this reduces the amount of collateral available for future secured debt or credit support and reduces our flexibility in operating these secured assets. This high level of debt and related security could have other important consequences for us, including:

• limiting our ability or increasing the costs to refinance our indebtedness;

• limiting our ability to borrow additional amounts for working capital, capital expenditures, debt service requirements, execution of our business strategy or other purposes;

• limiting our ability to use operating cash flow in other areas of our business because we must dedicate a substantial portion of these funds to service debt;

• increasing our vulnerability to general adverse economic and industry conditions, including increases in interest rates, particularly given our substantial indebtedness that bears interest at variable rates, as well as to catastrophic events; and

• limiting our ability to capitalize on business opportunities.

Under the terms of the agreements and indentures governing our indebtedness, including the Mortgage Indenture, we and our subsidiaries are permitted to incur additional indebtedness, some of which could be secured (subject to compliance with certain tests), and which could further accentuate these risks. As a result of our high level of indebtedness, we may be unable to generate sufficient cash through our operations to service our debt, including the mortgage bonds offered hereby, and we may need to refinance our indebtedness, including the mortgage bonds offered hereby, at or prior to maturity and be unable to obtain financing on suitable terms or at all, any of which could have a material adverse effect on our business, financial condition and results operations.

The documents that will govern our indebtedness following the Reorganization contain restrictions that limit our flexibility in operating our business.

Our material financing agreements, including certain credit agreements and indentures, will contain various covenants restricting, among other things, our ability to:

• incur or assume indebtedness or guarantees of indebtedness;

• incur or assume liens;

S-25

• sell or dispose of all or substantially all of its property or business;

• merge or consolidate with other companies;

• enter into any sale leaseback transactions; and

• enter into swap agreements.

The restrictions contained in these material financing agreements could affect our ability to operate our business and may limit our ability to react to market conditions or take advantage of potential business opportunities as they arise. For example, such restrictions could adversely affect our ability to finance our operations and expenditures, make strategic acquisitions, investments or alliances, restructure our organization or finance our capital needs. Additionally, our ability to comply with these covenants and restrictions may be affected by events beyond our control, including, but not limited to, prevailing economic, financial and industry conditions.

Parties may appeal the Confirmation Order, and the proceeds from this offering may be released from escrow despite any such appeal.

Following entry of the Confirmation Order confirming the Plan of Reorganization, parties will have a period of time to file a notice of appeal with respect to the Confirmation Order, including provisions related to the injunction contained in the Plan of Reorganization that channels certainpre-petitionfire-related claims to trusts to be satisfied from the trusts’ assets. Corp and the Company expect to proceed to consummate the Plan of Reorganization in accordance with its terms, even if a notice of appeal is timely filed, unless the party seeking the appeal also obtains a stay of implementation of the Plan of Reorganization pending its appeal, in which event Corp and the Company will not be able to implement the terms of the Plan of Reorganization unless and until the stay is lifted. An appeal of the Confirmation Order may proceed even if there is no stay pending appeal of the Confirmation Order and, in such circumstance, the appeal may be decided on its merits or the appeal may be dismissed as moot if, for example, Corp and the Company have implemented the Plan of Reorganization to the point of “substantial consummation” and the appellate court determines that the doctrine of equitable mootness applies to the appeal. If Corp and the Company proceed with consummating the Plan of Reorganization notwithstanding the filing of one or more notices of appeal and in the absence of a stay, then the proceeds from the sale of the mortgage bonds would be released from escrow on the Effective Date. The mortgage bonds would not be subject to special mandatory redemption following the occurrence of the Effective Date, even if any such appeal were successful. There can be no assurance that any such appeal will not be successful and, if successful, that any such appeal would not have a material adverse effect on Corp and the Company or the mortgage bonds.

Following our emergence from the Chapter 11 Cases, Corp and the Company will have a new Board of Directors.

On June 10, 2020, in connection with its expected emergence from Chapter 11, Corp announced the selection of a new Board of Directors to help guide the company post-bankruptcy. The new Board of Directors of Corp will consist of 14 members, 11 of whom are new. It is expected that the Board of Directors of the Company will largely be the same as Corp, with the Chief Executive Officer of the Company serving as an additional member.

The new directors who will serve on the Board of Directors of Corp and the Company following the Reorganization will have different backgrounds, experiences and perspectives from those individuals who have historically served on the Board of Directors and may have different views on the direction of our business and the issues that will determine our future and may have interests that conflict with your interests. The effect of implementation of those views and interests may be difficult to predict and may, in the short term, result in disruption to the strategic direction of the business. Additionally, the ability of new directors to quickly expand their knowledge of our operations will be critical to their ability to make informed decisions about our business and strategies.

S-26

We expect to be subject to claims that will not be discharged in the Chapter 11 Cases.

The Bankruptcy Code provides that the confirmation of a plan of reorganization discharges a debtor from substantially all debts arising prior to confirmation, other than as provided in the Plan of Reorganization or the Confirmation Order.

The Plan of Reorganization, however, provides that the holders of certain claims may pursue their claims against the Reorganized Debtors on or after the Effective Date, including, but not limited to, the following:

• claims arising after the January 29, 2019 petition date that constitute administrative expense claims (including any claims for fires occurring after the January 29, 2019 petition date), which will not be discharged pursuant to the Plan of Reorganization, other than allowed administrative expense claims that have been paid in cash or otherwise satisfied in the ordinary course in an amount equal to the allowed amount of such claim on or prior to the Effective Date;

• claims in the Ghost Ship fire litigation (with any recovery being limited to amounts available under Corp’s and the Company’s insurance policies for the 2016 year);

• claims arising out of or based on the 2019 Kincade fire, which is under investigation by the California Department of Forestry and Fire Protection and by CPUC, and may also be under investigation by various other entities, including law enforcement agencies; and

• certain FERC refund proceedings, workers’ compensation benefits and environmental claims.

Furthermore, holders of certain claims may assert that they are entitled under the Plan of Reorganization or the Bankruptcy Code to pursue, or continue to pursue, their claims against the Reorganized Debtors on or after the Effective Date, including but not limited to, claims arising from or relating to:

• the purportedde-energization securities class action filed in October 2019 and amended to add Corp in April 2020;

• the purported Public Safety Power Shutoff class action filed in December 2019 seeking up to $2.5 billion in special and general damages, punitive and exemplary damages and injunctive relief to require the Company to properly maintain and inspect its power grid, which was dismissed on April 3, 2020 and is subject to a notice of appeal filed on April 6, 2020; and

• indemnification or contribution claims, including with respect to the 2018 Camp fire, the 2017 Northern California wildfires, and the 2015 Butte fire.

In addition, claims continue to be pursued against Corp and the Company and certain of their respective current and former directors and officers as well as and certain underwriters, in connection with three purported securities class actions that have been consolidated and denominatedIn re PG&E Corporation Securities Litigation,U.S. District Court for the Northern District of California (the “Securities Litigation”). These claims consist of claims under the Federal securities laws related to, among other things, allegedly misleading statements or omissions with respect to vegetation management and wildfire disclosures. In addition to potential liability for claims asserted against Corp and the Company, Corp and the Company have ongoing obligations to indemnify their officers and directors in connection with this litigation. To the extent we or PG&E Corporation have any obligations to indemnify the underwriters in connection with this litigation, such obligations will be addressed in the Chapter 11 Cases and the Plan of Reorganization. Any such indemnification obligations could be material.

The claims that were asserted against Corp and the Company in the Securities Litigation were stayed as a result of the Chapter 11 Cases and will be resolved in connection with the Chapter 11 Cases through the claims resolution process in the Bankruptcy Court, and satisfied pursuant to the Plan of Reorganization, as described in more detail below. See “Plan of Reorganization—Satisfaction of HoldCo Rescission or Damage Claims and Subordinated Debt Claims.” As further described in “Plan of Reorganization—Satisfaction of HoldCo Rescission or Damage Claims and Subordinated Debt Claims,” these claims against Corp and the Company fall into two

S-27

categories, each of which is subject to subordination under the Bankruptcy Code. The total asserted amount of these claims filed on or before May 27, 2020 is approximately $2.3 billion of asserted claims based on Corp common stock holdings, $4.1 billion of asserted claims based on debt holdings, and $1.9 billion of asserted claims based on holdings not disaggregated between common stock and debt holdings. While these amounts include potentially duplicative and/or overstated claims as well as claims filed after the applicable bar date in the Chapter 11 Cases, they do not reflect unliquidated claims for which no claim amount was asserted. As a result, the amounts identified may not accurately reflect the amount of the claims that will be allowed and there can be no assurance that the amount of allowed claims will not exceed the foregoing amounts. While we believe there are defenses to these claims, including those asserted against officers, directors and underwriters, as well as insurance coverage that may be available in respect of the claims, these defenses may not prevail and any such insurance coverage may not be adequate to cover the full amount of the allowed claims. As a result, for the claims asserted against PG&E Corporation and the Company we may be required to (a) issue a material number of shares of common stock of PG&E Corporation with respect to claims based on PG&E Corporation common stockholdings, which, in turn, could result in additional shares of common stock of PG&E Corporation being issued to the Fire Victim Trust and (b) pay a material amount of cash with respect to claims based on debt holdings. See “Plan of Reorganization—Satisfaction of HoldCo Rescission or Damage Claims and Subordinated Debt Claims.”

The SEC’s investigation related to Corp’s and the Utility’s public disclosures and accounting for losses associated with the 2018 Camp fire, the 2017 Northern California wildfires and the 2015 Butte fire will also continue despite the Chapter 11 Cases, which could result in material costs, penalties, fires, sanctions or injunctive relief against Corp and the Company.

In addition, the Utility entered into a Plea Agreement and Settlement (the “Plea Agreement”) on March 17, 2020 with the People of the State of California, by and through the Butte County District Attorney’s office, to resolve the criminal prosecution of the Utility in connection with the 2018 Camp fire. Subject to the terms and conditions of the Plea Agreement, the Utility agreed to plead guilty to 84 counts of involuntary manslaughter in violation of Penal Code section 192(b) and one count of unlawfully causing a fire in violation of Penal Code section 452, and to admit special allegations pursuant to Penal Code sections 452.1(a)(2), 452.1(a)(3) and 452.1(a)(4). Pursuant to the Plea Agreement, the Utility will be sentenced to pay the maximum total fine and penalty of approximately $3.5 million. On April 16, 2020, the Bankruptcy Court approved the Plea Agreement. The Plea Agreement remains subject to approval and acceptance by the Butte County Superior Court, and there can be no assurance that such approval will be obtained. If the Plea Agreement is not approved and accepted, the CPUC or any other law enforcement agency could bring an enforcement action against Corp and the Company, which could result in the imposition of fines, other penalties or other sanctions.

Additional investigations and other actions may arise out of the other 2017 Northern California wildfires, the 2018 Camp fire, and the 2019 Kincade fire. The timing and outcome for resolution of the referrals by Cal Fire relating to the 2019 Kincade fire to the applicable county District Attorneys’ offices are uncertain.

For more information, you should read the related disclosure under the sections titled “Risk Factors” in Item 1A of Part I, “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Regulatory Matters—Transmission Owner Rate Cases” in Item 7 of Part II and Notes 2 and 14 of the Notes to the Consolidated Financial Statements of the 2019 Annual Report and Notes 2, 10 and 11 of the Q1 Quarterly Report incorporated by reference herein. The outcome and timing of these matters is uncertain, and it is possible that any one or more of these matters could result in material costs, penalties, fines, sanctions or injunctive relief against Corp and the Company. As a result, these matters could have a material impact on Corp’s and the Company’s financial condition, results of operations, liquidity, and cash flows, as well as on the ability of the Company to participate in the Wildfire Fund under AB 1054. The amount of potential losses could also exceed the amount of Corp’s and the Company’s insurance coverage for wildfire events. Moreover, even if the Company satisfies the eligibility and other requirements to participate in the Wildfire Fund under AB 1054, for eligible claims against the Company arising between July 12, 2019 and the Effective Date, the availability of the Wildfire Fund to pay such claims will be capped at 40% of the amount of such claims.

Risks Relating to the Mortgage Bonds

Perfection of the liens on the collateral securing the mortgage bonds will not be complete at closing, the proceeds from any sale of collateral may be insufficient to satisfy all the obligations secured by the collateral, and additional indebtedness may be secured on a pari passu basis.

Following the satisfaction of the Escrow Conditions, the mortgage bonds will be secured by a lien on substantially all of our real property and certain tangible personal property related to our facilities. In order to perfect the security interest in the real property collateral, following satisfaction of the Escrow Conditions, we will be required promptly to file or record the Mortgage Indenture in the proper real estate filing or recording offices of 48 counties in the State of California and financing statements with the Secretary of State of the State of California and pay all relevant filing and recording fees and until such time the liens on the collateral securing the mortgage bonds will not be perfected.

As of March 31, 2020, after giving effect to the Reorganization (including the Plan Financing Transactions), we would have had approximately $33,348 million of indebtedness outstanding secured on a pari passu basis by the collateral securing the mortgage bonds (including the New Utility Credit Agreements). If we are entitled to incur any additional mortgage bonds in accordance with the incurrence limitations in the Mortgage Indenture and we do so (including to serve as collateral for other debt), the holders thereof will be entitled to share ratably with you in any proceeds distributed in connection with any insolvency, liquidation, reorganization, dissolution or other winding up of our company. Given the extensive number of real properties subject to the lien of the Mortgage Indenture, certain provisions of California law that limit enforcement of remedies and the requirement for certain approvals for property transfers from regulatory authorities, we cannot assure you that the collateral securing the first mortgage bonds can be readily sold following an acceleration of maturity of the mortgage bonds, or that the proceeds of any such sale would be sufficient to satisfy amounts due on the mortgage bonds and any other debt secured by the collateral in full or at all.

Uncertainty relating to the calculation of LIBOR and other reference rates and their potential discontinuance may materially adversely affect the value of the floating rate mortgage bonds.

National and international regulators and law enforcement agencies have conducted investigations into a number of rates or indices which are deemed to be “reference rates.” Actions by such regulators and law enforcement agencies may result in changes to the manner in which certain reference rates are determined, their discontinuance, or the establishment of alternative reference rates. In particular, on July 27, 2017, the Chief Executive of the U.K. Financial Conduct Authority (the “FCA”), which regulates LIBOR, announced that the FCA will no longer persuade or compel banks to submit rates for the calculation of LIBOR after 2021. Such announcement indicates that the continuation of LIBOR on the current basis cannot and will not be guaranteed after 2021. Notwithstanding the foregoing, it appears highly likely that LIBOR will be discontinued or modified by 2021, which is prior to the maturity date of the floating rate mortgage bonds.

At this time, it is not possible to predict the effect that these developments, any discontinuance, modification or other reforms to LIBOR or any other reference rate, or the establishment of alternative reference rates may have on LIBOR, other benchmarks or floating rate debt securities, including the floating rate mortgage bonds. The market price of our floating rate mortgage bonds, in particular, will be influenced by the three-month LIBOR rate, volatility in such rate and events that affect LIBOR rates generally. Uncertainty as to the nature of such potential discontinuance, modification, alternative reference rates or other reforms may materially adversely affect the trading market for securities linked to such benchmarks, including the floating rate mortgage bonds. Furthermore, the use of alternative reference rates or other reforms could cause the interest rate calculated for the floating rate mortgage bonds to be materially different than expected.

If it is determined that LIBOR has been discontinued and an alternative reference rate for three-month LIBOR is used as described in “Description of the Mortgage Bonds—Interest—Floating Rate Mortgage Bonds”, we or our designee (a “Designee”) may make certain adjustments to such rate, including applying a spread

S-29

thereon or with respect to the business day convention, interest determination dates and related provisions and definitions, to make such alternative reference rate comparable to three-month LIBOR, in a manner that is consistent with industry-accepted practices or applicable regulatory or legislative actions or guidance for such alternative reference rate. See “Description of the Mortgage Bonds—Interest—Floating Rate Mortgage Bonds.” Any of the specified methods of determining floating rate alternative reference rates or the permitted adjustments to such rates may result in interest payments on your floating rate mortgage bonds that are lower than or that do not otherwise correlate over time with the payments that would have been made on the floating rate mortgage bonds if published LIBOR continued to be available. Other floating rate debt securities issued by other issuers, by comparison, may be subject in similar circumstances to different procedures for the establishment of alternative reference rates. Any of the foregoing may have a material adverse effect on the amount of interest payable on your floating rate mortgage bonds, or the market liquidity and market value of your floating rate mortgage bonds.

Interest on the floating rate mortgage bonds will be calculated using a Benchmark Replacement selected by us or our Designee if a Benchmark Transition Event occurs.

As described in detail in the section “Description of the Mortgage Bonds—Interest—Floating Rate Mortgage Bonds—Effect of Benchmark Transition Event” (the “benchmark transition provisions”), if during the term of the floating rate mortgage bonds, we (or our Designee) determine that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to LIBOR, we (or our Designee) in our sole discretion will select a Benchmark Replacement as the base rate in accordance with the benchmark transition provisions. The Benchmark Replacement will include a spread adjustment, and technical, administrative or operational changes described in the benchmark transition provisions may be made to the interest rate determination if we (or our Designee) determine in our sole discretion they are required.

Our interests (or the interests of our Designee) in making the determinations described above may be adverse to your interests as a holder of the floating rate mortgage bonds. The selection of a Benchmark Replacement, and any decisions made by us (or our Designee) in connection with implementing a Benchmark Replacement with respect to the floating rate mortgage bonds, could result in adverse consequences to the applicable interest rate on the floating rate mortgage bonds, which could adversely affect the return on, value of and market for such securities. Further, there is no assurance that the characteristics of any Benchmark Replacement will be similar to LIBOR or that any Benchmark Replacement will produce the economic equivalent of LIBOR.

The Secured Overnight Financing Rate (“SOFR”) is a relatively new market index and as the related market continues to develop, there may be an adverse effect on the return on or value of the floating rate mortgage bonds.

If a Benchmark Transition Event and its related Benchmark Replacement Date occur, then the rate of interest on the floating rate mortgage bonds will be determined using SOFR (unless a Benchmark Transition Event and its related Benchmark Replacement Date also occur with respect to the Benchmark Replacements that are linked to SOFR, in which case the rate of interest will be based on the next-available Benchmark Replacement). In the following discussion of SOFR, when we refer to SOFR-linked notes or debt securities, we mean the floating rate mortgage bonds at any time when the rate of interest on those notes or debt securities is or will be determined based on SOFR.

The Benchmark Replacements specified in the benchmark transition provisions include Term SOFR, a forward-looking term rate which will be based on SOFR. Term SOFR is currently being developed under the sponsorship of the Federal Reserve Bank of New York (the “NY Federal Reserve”), and there is no assurance that the development of Term SOFR will be completed. If a Benchmark Transition Event and its related Benchmark Replacement Date occur with respect to LIBOR and, at that time, a form of Term SOFR has not been selected or recommended by the Federal Reserve Board, the NY Federal Reserve, a committee thereof or

S-30

successor thereto, then the next-available Benchmark Replacement under the benchmark transition provisions will be used to determine the amount of interest payable on the floating rate mortgage bonds for the next applicable interest period and all subsequent interest periods (unless a Benchmark Transition Event and its related Benchmark Replacement Date occur with respect to that next-available Benchmark Replacement).

These replacement rates and adjustments may be selected or formulated by (i) the Relevant Governmental Body (as defined in the benchmark transition provisions) (such as the Alternative Reference Rates Committee of the NY Federal Reserve), (ii) the International Swaps and Derivatives Association, Inc., or (iii) in certain circumstances, us (or our Designee). In addition, the benchmark transition provisions expressly authorize us (or our Designee) to make Benchmark Replacement Conforming Changes with respect to, among other things, the determination of interest periods and the timing and frequency of determining rates and making payments of interest. The application of a Benchmark Replacement and Benchmark Replacement Adjustment, and any implementation of Benchmark Replacement Conforming Changes, could result in adverse consequences to the amount of interest payable on the floating rate mortgage bonds, which could adversely affect the return on, value of and market for the floating rate mortgage bonds. Further, there is no assurance that the characteristics of any Benchmark Replacement will be similar to the then-current Benchmark that it is replacing, or that any Benchmark Replacement will produce the economic equivalent of the then-current Benchmark that it is replacing.

The NY Federal Reserve began to publish SOFR in April 2018. Although the NY Federal Reserve has also begun publishing historical indicative SOFR going back to 2014, such prepublication historical data inherently involves assumptions, estimates and approximations. You should not rely on any historical changes or trends in SOFR as an indicator of the future performance of SOFR. Since the initial publication of SOFR, daily changes in the rate have, on occasion, been more volatile than daily changes in comparable benchmark or market rates. As a result, the return on and value of SOFR-linked debt securities may fluctuate more than floating rate debt securities that are linked to less volatile rates.

Also, since SOFR is a relatively new market index, SOFR-linked debt securities likely will have no established trading market when issued, and an established trading market may never develop or may not be very liquid. Market terms for debt securities indexed to SOFR, such as the spread over the index reflected in interest rate provisions, may evolve over time, and trading prices of the floating rate mortgage bonds may be lower than those of later-issued SOFR-linked debt securities as a result. Similarly, if SOFR does not prove to be widely used in securities like the floating rate mortgage bonds, the trading price of those securities may be lower than those of debt securities linked to rates that are more widely used. Debt securities indexed to SOFR may not be able to be sold or may not be able to be sold at prices that will provide a yield comparable to similar investments that have a developed secondary market, and may consequently suffer from increased pricing volatility and market risk.

The NY Federal Reserve notes on its publication page for SOFR that use of SOFR is subject to important limitations, indemnification obligations and disclaimers, including that the NY Federal Reserve may alter the methods of calculation, publication schedule, rate revision practices or availability of SOFR at any time without notice. There can be no guarantee that SOFR will not be discontinued or fundamentally altered in a manner that is materially adverse to you as a holder of the floating rate mortgage bonds. If the manner in which SOFR is calculated is changed or if SOFR is discontinued, that change or discontinuance may result in a reduction or elimination of the amount of interest payable on the floating rate mortgage bonds and a reduction in their trading prices.

Our ability to use some or all of our net operating loss carryforwards and other tax attributes to offset future income may be limited.

As of December 31, 2019, we and Corp, as a consolidated group, had net operating loss carryforwards for U.S. federal income tax purposes of approximately $5.7 billion. Pursuant to an order of the Bankruptcy Court, however, all trading and transfers of stock of the Debtors from and after the Petition Date and through the

S-31

consummation of the Plan of Reorganization are subject to certain restrictions and other requirements imposed to protect the potential value of the Debtors’ consolidated net operating loss carryforwards and other tax benefits.

Following the Effective Date, any net operating loss carryforwards and certain other tax attributes allocable to periods prior to the Effective Date may be subject to certain limitations. Under Section 382 of the Internal Revenue Code, if a corporation (or a consolidated group) undergoes an “ownership change,” and the corporation does not qualify for (or elects out of) the special bankruptcy exception in Section 382(l)(5) of the Internal Revenue Code, such net operating loss carryforwards and other tax attributes may be subject to certain limitations. In general, an ownership change occurs if the aggregate stock ownership of certain shareholders (generally 5% shareholders, applying certainlook-through and aggregation rules) increases by more than 50% over such shareholders’ lowest percentage ownership during the testing period (generally three years). Losses incurred in the same taxable year as an ownership change generally can bepro-rated between thepre- and post-change portions of the taxable year, even if a disproportionate amount of such losses were actually incurred on or prior to the date of the ownership change. Only the portion of such losses allocated to thepre-change portion of the year would be subject to the annual limitation.

Whether we and Corp will undergo an ownership change as a result of the transactions occurring pursuant to the Plan of Reorganization, whether such change will qualify for the exception in Section 382(l)(5) of the Internal Revenue Code, and whether the limitation under Section 382 if we and Corp do undergo an ownership change that does not qualify for (or that we elect out of) the special bankruptcy exception in Section 382(l)(5) will be material to our operations is uncertain and will depend in part on the results of the transactions in Corp’s equity occurring as part of the Plan of Reorganization. Even if these transactions do not cause an ownership change, they could increase the likelihood that we and Corp may undergo an ownership change for purposes of Section 382 of the Internal Revenue Code in the future.

Limitations imposed on our and Corp’s ability to utilize net operating loss carryforwards or other tax attributes could cause U.S. federal income taxes to be paid earlier than would be paid if such limitations were not in effect and could cause such net operating loss carryforwards or other tax attributes to expire unused, in each case reducing or eliminating the benefit of such net operating loss carryforwards and other tax attributes. Specifically, our and Corp’s ability to utilize its net operating loss carryforwards is critical to a successful rate-neutral securitization transaction after the Effective Date, the proceeds of which are expected to be used to satisfy our and Corp’s obligations to the Fire Victim Trust and commitment to make certain operating and capital expenditures. Failure to consummate a securitization transaction or obtain alternative sources of capital could have a material adverse effect on our ability to satisfy our obligations with respect to the mortgage bonds.

USE OF PROCEEDS

The aggregate net proceeds from this offering are estimated to be approximately $                , after deducting the respective underwriting discounts and before estimated offering expenses payable by us.

The aggregate net proceeds of this offering will be placed in escrow if the Escrow Conditions are not satisfied prior to the closing date. Pending release from escrow, the aggregate net proceeds will be invested in Permitted Investments (as defined under “Description of the Mortgage Bonds—Escrow of Net Proceeds; Special Mandatory Redemption”). If the Escrow Conditions are not satisfied on or prior to September 9, 2020 (or such earlier date as we determine in our sole discretion that any of the Escrow Conditions cannot be satisfied), the mortgage bonds offered hereby will be subject to a special mandatory redemption at a redemption price of 101% of the principal amount of the mortgage bonds offered hereby, plus accrued and unpaid interest to, but not including, the redemption date.

Concurrently with the satisfaction of the Escrow Conditions, the escrowed funds will be released and we and Corp intend to use the net proceeds from this offering, together with the net proceeds from the other Plan Financing Transactions described under “Plan of Reorganization—Plan Financing Transactions,” to effectuate the Reorganization in accordance with the terms and conditions contained in the Plan of Reorganization.

S-33

The following table sets forth the estimated sources and uses of funds (assuming an Effective Date of June 30, 2020) in connection with the Reorganization on a consolidated basis and includes the Plan Financing Transactions as well as the other financing transactions that the Debtors expect to consummate in connection with the Reorganization. The actual sources and uses of funds and the actual amounts thereof may vary from the estimated sources and uses of funds and the estimated amounts thereof in the table and accompanying footnotes set forth below. In particular, the amounts set forth below may differ at the time of the consummation of the Plan of Reorganization depending on several factors, including, without limitation, differences at the date of consummation in the amount of our and Corp’s outstanding debt and accrued interest, changes in our and Corp’s cash and cash equivalents and differences from our estimation of fees and expenses. You should read the following together with the information included under the headings “Prospectus Summary—Recent Developments,” “Summary Historical Financial and Operating Information”, “Capitalization” and “Plan of Reorganization” included elsewhere in this prospectus supplement.

Notes:

(1) See “Plan of Reorganization—Plan Financing Transactions” for further detail on the financing transactions to be consummated by us in connection with the Reorganization.

(2) Corp expects to raise an aggregate of approximately $9,000 million of gross proceeds in cash through the PIPE Transaction and the issuance of shares of its common stock and/or other equity and/or equity-linked securities pursuant to one or more offerings and/or private placements.

(3) Represents the value of PG&E Corporation common stock to be issued to the Fire Victim Trust determined in accordance with the Plan of Reorganization, based on Fire Victim Equity Value (as such term is defined in the Plan of Reorganization). The issuance of PG&E Corporation common stock to the Fire Victim Trust will not result in any cash proceeds to PG&E Corporation, but will discharge a portion of the Fire claims settlement (at emergence). The issuance of PG&E Corporation common stock to the Fire Victim Trust will represent 22.19% of the outstanding common stock of reorganized PG&E Corporation as of the Effective Date, subject to potential adjustments, in accordance with the Plan of Reorganization.

Fire claims settlement (at emergence) represents compensation to be paid on the Effective Date to holders of wildfire-related claims to resolve their claims pursuant to the Plan of Reorganization. The total compensation of $24,215 million consists of (i) (x) $5,400 million to be paid to the Fire Victim Trust in

S-34

cash and (y) an assumed $6,750 million to be paid to the Fire Victim Trust in shares of common stock of PG&E Corporation described in the immediately preceding paragraph, (ii) $11,055 million (inclusive of fees) to be paid in cash to the Subrogation Wildfire Trust and (iii) $1,010 million (inclusive of fees) to be paid to the Settling Public Entities.

In addition, $1,350 million of additional cash payments to the Fire Victim Trust in respect of wildfire claims settlement amounts will be deferred, which, based on the sources and uses outlined above and assuming the Effective Date were to occur on June 30, 2020, would consist of (i) $650 million to be paid on or before January 15, 2021 and (ii) $700 million to be paid on or before January 15, 2022.

(4) To the extent the Company raises more than $5,925 million in this offering of mortgage bonds, the commitments under the New Utility364-Day Term Loan facility will be reduced by such amount. To the extent Corp raises more or less than $3,750 million in the concurrent notes offering, the commitments under the New HoldCo Term Loan Facility would be reduced or increased, respectively, by such amount.

(5) Contribution to wildfire fund represents required payments under AB 1054 for the Company to participate in the Wildfire Fund. These payments are comprised of an initial contribution of approximately $4,800 million and an initial annual contribution of approximately $193 million.

(6) DIP Facilities represents the projected amount that will be required in order to repay all amounts outstanding under the DIP Facilities on the Effective Date. As of March 31, 2020, we had $2,000 million of borrowings outstanding under the DIP Facilities, and $774 million of letters of credit. As of May 31, 2020, we had $2,000 million of borrowings outstanding under the DIP Facilities, and $972 million of letters of credit. Letters of credit under the DIP revolving facility at the Effective Date will become outstanding under the New Utility Revolving Credit Facility on the Effective Date.

(7) Pre-petition debt represents the aggregate principal amount ofpre-petition debt of Corp or the Company to be repaid on the Effective Date, consisting of (i) $650 million ofpre-petition debt of Corp to be repaid in cash pursuant to the Plan of Reorganization, (ii) $6,200 million ofpre-petition senior notes of the Company to be exchanged for New Utility Long-Term Bonds pursuant to the Utility Debt Refinancing under the Plan of Reorganization, (iii) $1,750 million ofpre-petition senior notes of the Company to be exchanged for New Utility Short-Term Bonds pursuant to the Utility Debt Refinancing under the Plan of Reorganization, (iv) $3,898 million ofpre-petition indebtedness of the Company (including obligations under certain series of pollution control bonds) to be exchanged for New Utility Funded Debt Exchange Bonds pursuant to the Utility Debt Refinancing under the Plan of Reorganization, (v) $9,575 million ofpre-petition senior notes of the Company to be reinstated pursuant to the Utility Debt Reinstatement under the Plan of Reorganization and (vi) $100 million of pollution control bonds (Series 2008F and 2010E) to be repaid in cash pursuant to the Plan of Reorganization.

(8) Trade claims and other costs represents estimated trade claims and other costs, including trade payables, other liabilities subject to compromise and professional and transaction fees, to be paid by Corp or the Company on the Effective Date.

(9) The total accrued interest figure in the table above includes the aggregate amount ofpre-petition accrued interest and post-petition accrued interest on Corp’s and the Company’spre-petition debt to the Effective Date, estimated to be June 30, 2020 for purposes of this table. The total accrued interest figure includes the aggregate amount of accrued interest on the Utility Reinstated Senior Notes to the Effective Date, a portion of which will be paid on the next ensuing interest payment date.

(10) Insurance proceeds represents proceeds of Corp’s and the Company’s liability insurance policies for wildfire events. See “Insurance” in Note 14 of the 2019 Annual Report for more information.

(11) Corp and the Company had consolidated cash and cash equivalents of $1,960 million as of March 31, 2020, and $774 million as of May 31, 2020. To the extent cash and cash equivalents are insufficient for the purpose of funding the uses described above, we expect to draw on available working capital facilities, including our revolving credit facilities.

CAPITALIZATION

The following table sets forth our cash and cash equivalents and capitalization as of March 31, 2020 on an (i) actual basis and (ii) as adjusted basis, after giving effect to the Reorganization and the Plan Financing Transactions to be carried out by us (including the issuance of the mortgage bonds in this offering and the application of the net proceeds therefrom, as described in the section titled “Use of Proceeds”), as if such transactions occurred on March 31, 2020. You should read this table in conjunction with the financial statements and the related notes incorporated by reference in this prospectus supplement and the accompanying prospectus, together with the information included under the headings “Prospectus Summary—Recent Developments,” “Summary Historical Financial and Operating Information,” “Capitalization” and “Plan of Reorganization” included elsewhere in this prospectus supplement.

Notes:

(1) As of May 31, 2020, the Company had consolidated cash and cash equivalents of $400 million. The net decrease in cash from March 31, 2020 to May 31, 2020 was primarily attributable to (i) normal seasonal fluctuations in cash receipts and disbursements, which resulted in a net use of cash during the period, (ii) decreased cash receipts attributable to theCOVID-19 pandemic and the temporary relief afforded to customers via the voluntary suspension of service disconnections for lack of payment and (iii) net decline in energy usage.

(2) As adjusted cash and cash equivalents does not reflect deferred cash expenditures of $1,350 million for certain cash payments to the Fire Victim Trust in respect of wildfire claims settlement amounts under the TCC RSA, as set forth in the “Uses of Funds” table and related footnotes under “Use of Proceeds”. Based on the sources and uses set forth under “Sources and Uses,” the deferred amounts would consist of (i) $650 million to be paid on or before January 15, 2021 and (ii) $700 million to be paid on or before January 15, 2022 (the timing of which may be accelerated in connection with certain securitization transactions, but in no event prior to January 15, 2021). To the extent cash and cash equivalents are insufficient for the purpose of funding the uses set forth in the “Uses of Funds” table and related footnotes under “Use of Proceeds,” we expect to draw on available working capital facilities, including our revolving credit facility.

(3) Reflects total accrued contractual interest to the Petition Date.

(4) Post-petition interest has been calculated in accordance with the terms and conditions contained in the Plan of Reorganization. Per the Plan of Reorganization, interest on the Utility Reinstated Senior Notes will accrue at the contractual rate and interest on the Utility Short-Term Senior Notes, the Utility Long-Term Senior Notes, and Utility Funded Debt will accrue at the Federal Judgement Rate.

(5) As part of the Reorganization, the Company’s indebtedness related to the series of pollution control bonds outstanding as of the Petition Date will be either be (i) repaid in cash or (ii) receive a combination of cash and New Utility Funded Debt Exchange Bonds, in each case in satisfaction of related claims in accordance with the terms and conditions contained in the Plan of Reorganization.

(6) As of March 31, 2020, the Company had written off $178 million of unamortized debt issuance costs and debt discount to present the debt subject to compromise at the outstanding face value.

(7) The DIP revolving facility provides for borrowings and letters of credit in an aggregate amount of $3,500 million. As of March 31, 2020, we had revolving commitments available to be borrowed of $2,726 million (after taking into account $774 million of letters of credit and no revolving loans then outstanding). As of May 31, 2020, we had revolving commitments available to be borrowed under the DIP revolving facility of $2,528 million (after taking into account $972 million of letters of credit and no revolving loans then outstanding).

(8) As of the Effective Date, we expect to have approximately $3,500 million of revolving commitments available to be borrowed under the New Utility Revolving Credit Facility. Letters of credit under the DIP revolving facility at the Effective Date will become outstanding under the New Utility Revolving Credit Facility on the Effective Date and will reduce available borrowing capacity. In addition, to the extent cash and cash equivalents as of the Effective Date are insufficient for the purpose of funding the uses described under the heading “Uses of Funds” under “Use of Proceeds,” we expect to draw on the New Utility Revolving Credit Facility. Whether such a drawing is required will depend on a number of factors, including the timing of various cash receipts and payments in connection with the Plan (including receipt of Insurance proceeds and payment of trade payables) and the amount of cash and cash equivalents on hand at the Utility as of the Effective Date.

(9) To the extent the Company raises more than $5,925 million in this offering of mortgage bonds, the commitments under the New Utility364-Day Term Loan Facility will be reduced by such amount.

OUR BUSINESS

Overview

We are one of the largest combination natural gas and electric utilities in the United States. We were incorporated in California in 1905 and are a subsidiary of PG&E Corporation. We provide natural gas and electric service to approximately 16 million people throughout a70,000-square-mile service area in northern and central California. We generate revenues mainly through the sale and delivery of electricity and natural gas to customers. As of December 31, 2019, approximatelytwo-thirds of our revenues were associated with owning and operating gas, electric and generation infrastructure. The remaining third were pass-through costs primarily associated with commodity procurement. We had approximately $86.15 billion in assets at March 31, 2020 and generated operating revenues of approximately $17.1 billion in 2019.

At December 31, 2019, we owned approximately 18,000 circuit miles of interconnected transmission lines operating at voltages ranging from 60 kV to 500 kV. We also operated 33 electric transmission substations with a capacity of approximately 65,000 MVA. Our electric transmission system is interconnected with electric power systems in the Western Electricity Coordinating Council, which includes many western states, the Canadian provinces of Alberta and British Columbia, and parts of Mexico.

Our electric distribution network consists of approximately 107,000 circuit miles of distribution lines (of which, as of December 31, 2019, approximately 25% are underground and approximately 75% are overhead), 68 transmission switching substations, and 760 distribution substations, with a capacity of approximately 32,000 MVA.

At December 31, 2019, our natural gas system consisted of approximately 43,300 miles of distribution pipelines, over 6,300 miles of backbone and local transmission pipelines, and various storage facilities. We own and operate eight natural gas compressor stations on our backbone transmission system and one small station on our local transmission system that are used to move gas through our pipelines.

We are regulated primarily by the CPUC and the FERC. The CPUC has jurisdiction over the rates and terms and conditions of service for our electric and natural gas distribution operations, electric generation, and natural gas transmission and storage services. The CPUC also has exercised jurisdiction over our issuances of securities, dispositions of utility assets and facilities, energy purchases on behalf of our electric and natural gas retail customers, rates of return, rates of depreciation, oversight of nuclear decommissioning, and aspects of the siting of facilities used in providing electric and natural gas utility service. Our ability to recover revenue requirements authorized by the CPUC in these rate cases is independent or “decoupled” from the volume of our sales of electricity and natural gas services. As a result, our base revenues are not impacted by fluctuations in sales resulting from, for example, weather or economic conditions.

On December 19, 2019, the CPUC issued a final decision that authorized our capital structure and rates of return for our electric generation, electric and natural gas distribution, and natural gas transmission and storage rate base through 2023, consisting of 52% common equity, 47.5% long-term debt, and 0.5% preferred stock. The CPUC also set the authorized ROE through 2023 at 10.25% and reset the cost of debt to 5.16%. The CPUC also authorized the continuation of an adjustment mechanism to allow our cost of debt and ROE to be adjusted if the utility bond index changes by certain thresholds, which are reviewed annually. In our cost of capital proceedings, we acknowledged that our cost of long-term debt for cost of capital purposes may be different than the approved cost upon our emergence from the Chapter 11 Cases. To account for this possible difference, we proposed to update our cost of debt for cost of capital purposes for the period beginning after our emergence from the Chapter 11 Cases to incorporate the costs of our exit financing, and the appropriate forward-looking forecast of debt costs for the remaining forecast period. The CPUC found our proposal to be reasonable and adopted it.

On May 28, 2020, the CPUC approved, with conditions and modifications, the Plan of Reorganization and found that it satisfies the requirements of AB 1054 (the “Plan of Reorganization OII”). Pursuant to the Plan of

S-38

Reorganization OII, changes to the Company’s governance structure and enhancements to the CPUC’s oversight are put in place to facilitate the Company’s ability to provide safe, reliable and affordable utility service. In addition, we committed to develop a regional reorganization plan for our business lines to create local operating regions that place leadership and operations closer to our customers. Each region will be led by an officer who reports directly to our CEO and will have a safety officer who reports directly to the Chief Safety Officer. We are required by the CPUC to file an application for regionalization by June 30, 2020 and to appoint regional executive officers and regional safety officers to manage each region by June 1, 2021. The CPUC’s final decision approving the Plan of Reorganization was issued on June 1, 2020.

The FERC has jurisdiction over our electric transmission revenue requirements and rates, the licensing of substantially all of our hydroelectric generation facilities, and the interstate sale and transportation of natural gas. Under the formula rate mechanism, transmission revenue requirements will be updated to the actual cost of service annually as part of thetrue-up process.

In addition, the NRC oversees the licensing, construction, operation, and decommissioning of our nuclear generation facilities.

We provide natural gas transportation services to “core” customers (i.e., small commercial and residential customers) and to“non-core” customers (i.e., industrial, large commercial, and naturalgas-fired electric generation facilities) that are connected to our gas system in our service territory. Core customers can purchase natural gas procurement service (i.e., natural gas supply) from either us ornon-utility third-party gas procurement service providers (referred to as “core transport agents”). When core customers purchase gas supply from a core transport agent, we continue to provide gas delivery, metering and billing services to customers. When we provide both transportation and procurement services, we refer to the combined service as “bundled” natural gas service. Currently, more than 97% of core customers, representing approximately 82% of the annual core market demand, receive bundled natural gas service from us.

Electric Utility Operations

The Company generates electricity and provides electric transmission and distribution services throughout its service territory in northern and central California to residential, commercial, industrial, and agricultural customers. The Company provides “bundled” services (i.e., electricity, transmission and distribution services) to customers in its service territory. Customers also can obtain electricity from alternative providers such as municipalities or CCAs, as well as from self-generation resources, such as rooftop solar installations. (For more information, see “Regulatory Matters” in Item 7. of the Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) of the 2019 Annual Report.)

Electricity Resources

The Company is required to maintain capacity adequate to meet its customers’ demand for electricity (“load”), including peak demand and planning and operating reserves, deliverable to the locations and at times as may be necessary to provide reliable electric service. The Company is required to dispatch, or schedule all of the electric resources within its portfolio using least-cost dispatch.

The following table shows the percentage of the Company’s total deliveries of electricity to customers in 2019 represented by each major electric resource, and further discussed below.

(1) This amount excludes electricity provided by direct access providers and CCAs that procure their own supplies of electricity for their respective customers.

(2) The allocation of bundled retail sale amounts and “Others, Net” in the “Power Content Label” column is consistent with current CEC guidelines, applied to specified electric generation and procurement volumes (i.e., fossil fuel-fired, nuclear, large hydroelectric, and renewable). Total reported generation and procurement volumes equate to actual electric retail sales.

(3) Amount is mainly comprised of net CAISO open market (sales)/purchases.

Renewable Energy Resources

California law established an RPS that requires load-serving entities, such as the Company, to gradually increase the amount of renewable energy they deliver to their customers. In October 2015, the California Governor signed SB 350, the Clean Energy and Pollution Reduction Act of 2015 into law. SB 350 became effective January 1, 2016, and increases the amount of renewable energy that must be delivered by most load-serving entities, including the Company, to their customers from 33% of their total annual retail sales by the end of the 2017-2020 compliance period, to 50% of their total annual retail sales by the end of the 2028- 2030 compliance period, and in each three-year compliance period thereafter, unless changed by legislative action. SB 350 provides compliance flexibility and waiver mechanisms, including increased flexibility to apply excess renewable energy procurement in one compliance period to future compliance periods. In September 2018, the California Governor signed SB 100 into law, increasing from 50% to 60% of California’s electricity portfolio

S-40

that must come from renewables by 2030; and established state policy that 100 percent of all retail electricity sales must come fromRPS-eligible or carbon-free resources by 2045. The Company may incur additional costs to procure renewable energy to meet the new renewable energy targets, which the Company expects will continue to be recoverable from customers as “pass-through” costs. The Company also may be subject to penalties for failure to meet the higher targets. The CPUC is required to open a new rulemaking proceeding to adopt regulations to implement the higher renewable targets.

Renewable generation resources, for purposes of the RPS requirements, include bioenergy such as biogas and biomass, certain hydroelectric facilities (30 MW or less), wind, solar, and geothermal energy. RPS requirements are based on actual procurement, which aligns with the methodology presented in the first column of the table above. Actual procurement from renewable energy sources was 29.7% in 2019. Per the Power Content Label methodology presented in the table above, 27.4% of the Company’s energy deliveries were from renewable energy sources.

The total 2019 renewable deliveries shown above were comprised of the following:

Type	GWh		Percent of Bundled Retail Sales
Biopower		1,322		3.7	%
Geothermal		539		1.5	%
Wind		3,412		9.5	%
RPS-Eligible Hydroelectric		827		2.3	%
Solar		4,574		12.7	%
Total		10,674		29.7	%

Energy Storage

As required by California law, the CPUC established a multi-year energy storage procurement framework, including energy storage procurement targets to be achieved by each load-serving entity under the CPUC jurisdiction, including the Company. Under the adopted energy storage procurement framework, the Company is required to procure 580 MW of qualifying storage capacity by the end of 2021, with all energy storage projects required to be operational by the end of 2024.

The CPUC also adopted biennial interim storage targets for the Company, beginning in 2014 and ending in 2020. Under the adopted framework, the Company is required to submit biennial energy storage procurement plans to describe its strategy to meet its interim and total energy storage targets.

Through its procurements to date, the Company has largely met its storage targets. The Company expects to meet its remaining target through existing customer programs. This outcome may change in the future if projects under contract are terminated or if projects fail to be developed.

(1) The Company’s Diablo Canyon power plant consists of two nuclear power reactor units, Units 1 and 2. The NRC operating licenses expire in 2024 and 2025, respectively. On January 11, 2018, the CPUC approved the Company’s application to retire Unit 1 by 2024 and Unit 2 by 2025. (See “Diablo Canyon Nuclear Power Plant” in Item 7. MD&A and Item 3. Legal Proceedings in the 2019 Annual Report.)

(2) The Company’s hydroelectric system consists of 105 generating units at 66 powerhouses. All of the Company’s powerhouses are licensed by the FERC (except for two small powerhouses not subject to FERC licensing requirements), with license terms between 30 and 50 years.

(3) The Company’s large photovoltaic facilities are Cantua solar station (20 MW), Five Points solar station (15 MW), Gates solar station (20 MW), Giffen solar station (10 MW), Guernsey solar station (20 MW), Huron solar station (20 MW ), Stroud solar station (20 MW), West Gates solar station (10 MW), and Westside solar station (15 MW). All of these facilities are located in Fresno County, except for Guernsey solar station, which is located in Kings County.

Generation Resources from Third Parties

The Company has entered into various agreements to purchase power and electric capacity, including agreements for renewable energy resources, in accordance with its CPUC-approved procurement plan. For more information regarding the Company’s power purchase agreements, see Item 1. “Business” and Note 15 of the Notes to the Consolidated Financial Statements in Item 8 of the 2019 Annual Report.

Electricity Transmission

At December 31, 2019, the Company owned approximately 18,000 circuit miles of interconnected transmission lines operating at voltages ranging from 60 kV to 500 kV. The Company also operated 33 electric transmission substations with a capacity of approximately 65,000 MVA. The Company’s electric transmission system is interconnected with electric power systems in the Western Electricity Coordinating Council, which includes many western states, the Canadian provinces of Alberta and British Columbia, and parts of Mexico.

Decisions about expansions and maintenance of the transmission system can be influenced by decisions of the Company’s regulators and the CAISO.

S-42

Electricity Distribution

The Company’s electric distribution network consists of approximately 107,000 circuit miles of distribution lines (of which, as of December 31, 2019, approximately 25% are underground and approximately 75% are overhead), 68 transmission switching substations, and 760 distribution substations, with a capacity of approximately 32,000 MVA. The Company’s distribution network interconnects with its transmission system, primarily at switching and distribution substations, where equipment reduces the high-voltage transmission voltages to lower voltages, ranging from 44 kV to 2.4 kV, suitable for distribution to the Company’s customers.

These distribution substations serve as the central hubs for the Company’s electric distribution network. Emanating from each substation are primary and secondary distribution lines connected to local transformers and switching equipment that link distribution lines and provide delivery toend-users. In some cases, the Company sells electricity from its distribution facilities to entities, such as municipal and other utilities, that resell the electricity. The Company operates electric distribution control center facilities in Concord, Rocklin, and Fresno, California; these control centers form a key part of the Company’s efforts to create a smarter, more resilient grid.

Electricity Operating Statistics

The following table shows certain of the Company’s operating statistics from 2017 to 2019 for electricity sold or delivered, including the classification of revenues by type of service.

Natural Gas Utility Operations

The Company provides natural gas transportation services to “core” customers (i.e., small commercial and residential customers) and to“non-core” customers (i.e., industrial, large commercial, and naturalgas-fired electric generation facilities) that are connected to the Company’s gas system in its service territory. Core customers can purchase natural gas procurement service (i.e., natural gas supply) from either the Company ornon-utility third-party gas procurement service providers (referred to as “core transport agents”). When core customers purchase gas supply from a core transport agent, the Company continues to provide gas delivery, metering and billing services to customers. When the Company provides both transportation and procurement services, the Company refers to the combined service as “bundled” natural gas service. Currently, more than 97% of core customers, representing approximately 82% of the annual core market demand, receive bundled natural gas service from the Company.

The Company generally does not provide procurement service tonon-core customers, who must purchase their gas supplies from third-party suppliers, unless the customer is a naturalgas-fired generation facility with which the Company has a power purchase agreement that includes its generation fuel expense. The Company offers backbone gas transmission, gas delivery (local transmission and distribution), and gas storage services as separate and distinct services to itsnon-core customers. Access to the Company’s backbone gas transmission system is available for all natural gas marketers and shippers, as well asnon-core customers. The Company also delivers gas tooff-system customers (i.e., outside of the Company’s service territory) and to third-party natural gas storage customers.

Natural Gas Supplies

The Company can receive natural gas from all the major natural gas basins in western North America, including basins in western Canada, the Rocky Mountains, and the southwestern United States. The Company can also receive natural gas from fields in California. The Company purchases natural gas to serve its core customers directly from producers and marketers in both Canada and the United States. The contract lengths and natural gas sources of the Company’s portfolio of natural gas purchase contracts have varied generally based on market conditions. During 2019, the Company purchased approximately 282,000 MMcf of natural gas (net of the sale of excess supply of gas). Substantially all of this natural gas was purchased under contracts with a term of one year or less. The Company’s largest individual supplier represented approximately 20% of the total natural gas volume the Company purchased during 2019.

Natural Gas System Assets

The Company owns and operates an integrated natural gas transmission, storage, and distribution system that includes most of northern and central California. At December 31, 2019, the Company’s natural gas system consisted of approximately 43,300 miles of distribution pipelines, over 6,300 miles of backbone and local transmission pipelines, and various storage facilities. The Company owns and operates eight natural gas compressor stations on its backbone transmission system and one small station on its local transmission system that are used to move gas through the Company’s pipelines. The Company’s backbone transmission system, composed primarily of Lines 300, 400, and 401, is used to transport gas from the Company’s interconnection with interstate pipelines, other local distribution companies, and California gas fields to the Company’s local transmission and distribution systems.

The Company has firm transportation agreements for delivery of natural gas from western Canada to the United States-Canada border with TransCanada NOVA Gas Transmission, Ltd. interconnecting downstream with TransCanada Foothills Pipe Lines Ltd., B.C. System. The Foothills system interconnects at the border to the pipeline system owned by Gas Transmission Northwest, LLC, which provides natural gas transportation services to a point of interconnection with the Company’s natural gas transportation system on the Oregon-California border near Malin, Oregon. The Company also has firm transportation agreements with Ruby Pipeline, LLC to

S-44

transport natural gas from the U.S. Rocky Mountains to the interconnection point with the Company’s natural gas transportation system in the area of Malin, Oregon, at the California border. Similarly, the Company has a firm transportation agreement with Transwestern Pipeline Company, LLC to transport natural gas from supply points in the Southwestern United States to interconnection points with the Company’s natural gas transportation system in the area of California near Topock, Arizona. (For more information regarding the Company’s natural gas transportation agreements, see Note 15 of the Notes to the Consolidated Financial Statements in Item 8 of the 2019 Annual Report.)

The Company owns and operates three underground natural gas storage fields and has a 25% interest in a fourth storage field, all of which are connected to the Company’s transmission system. The Company owns and operates compressors and other facilities at these storage fields that are used to inject gas into the fields for storage and later withdrawal. In addition, four independent storage operators are interconnected to the Company’s northern California transmission system. In 2019, the CPUC approved the discontinuation (through closure or sale) of operations at two gas storage fields. (For more information, see “Regulatory Matters—2019 Gas Transmission and Storage Rate Case” in Item 7. MD&A of the 2019 Annual Report.)

In 2019, the Company continued upgrading transmission pipeline to allow for the use ofin-line inspection tools and continued its work on the final NTSB recommendation from its San Bruno investigation to hydrostatically test all high consequence pipeline mileage. The Company currently plans to complete this NTSB recommendation by 2022 for remaining short pipeline segments that includetie-in pieces, fittings or smaller diameteroff-takes from the larger transmission pipelines.

Competition

Competition in the Electricity Industry

California law allows qualifyingnon-residential electric customers of investor-owned electric utilities to purchase electricity from energy service providers rather than from the utilities up to certain annual and overall GWh limits that have been specified for each utility. This arrangement is known as “direct access,” or DA. In 2018, the California legislature passed a bill to expand the statewide DA cap by 4,000 GWh, and directed the CPUC to consider whether DA should be further expanded, and to present a report on this matter to the legislature by June 30, 2020. In addition, California law permits cities, counties, and certain other public agencies that have qualified to become a CCA to generate and/or purchase electricity for their local residents and businesses. By law, a CCA can procure electricity for all of its residents and businesses that do not affirmatively elect to continue to receive electricity generated or procured by a utility. On June 3, 2019, the CPUC issued an order implementing the 4,000 GWh increase for DA transactions, including an apportionment to the Company’s service area of approximately 1,873 GWh. The CPUC is currently conducting a study to inform its

S-46

recommendations to the legislature on implementing a further direct transaction reopening schedule. However, the issuance of a proposed decision on these issues has been delayed indefinitely as a result of theCOVID-19 pandemic.

The Company continues to provide transmission, distribution, metering, and billing services to direct access customers, although these customers can choose to obtain metering and billing services from their energy service provider. The CCA customers continue to obtain transmission, distribution, metering, and billing services from the Company. In addition to collecting charges for transmission, distribution, metering, and billing services that it provides, the Company is able to collect charges intended to recover the generation-related costs that the Company incurred on behalf of direct access and CCA customers while they were the Company’s customers. The Company remains the electricity provider of last resort for these customers. SB 520 (codified at Section 387 of the Public Utilities Code), which was signed by the governor and became law on October 2, 2019, allows for a request to transfer the responsibilities of the provider of last resort obligation from investor-owned utilities to other entities.

The Company is also impacted by the increasing viability of distributed generation and energy storage. The levels of self-generation of electricity by customers (primarily solar installations) and the use of customer net energy metering (“NEM”), which allows self-generating customers employing qualifying renewable resources to receive bill credits at the full retail rate, are increasing, putting upward rate pressure on remaining customers. New NEM customers are required to pay an interconnection fee, utilize time of use rates, and are required to pay certainnon-bypassable charges to help fund some of the costs of low income, energy efficiency, and other programs that other customers pay. Significantly higher bills for remaining customers may result in a decline of the number of such customers as they may seek alternative energy providers or adopt self-generation technologies. The CPUC has indicated that it intends to commence a new proceeding to revisit its rules related to NEM customers in 2020.

Further, in some circumstances, governmental entities such as cities and irrigation districts, which have authority under the state constitution or state statute to provide retail electric service, may seek to acquire the Company’s distribution facilities, through eminent domain (although eminent domain is stayed while the Company is in Chapter 11, unless the Bankruptcy Judge lifts the stay). In 2019, three entities communicated an interest in acquiring certain Company assets through a voluntary sale during the bankruptcy. It is also possible that some of the governmental entities interested in acquiring the Company’s assets will construct duplicate distribution facilities to serve existing or potential new Company customers.

The Company also competes for the opportunity to develop and construct certain types of electric transmission facilities within, or interconnected to, its service territory through a competitive bidding process managed by the CAISO.

The effect of such types of retail competition generally is to reduce the number of utility customers, leading to a reduction in the amount of electricity purchased from the Company.

For risks in connection with increasing competition, see Item 1A. Risk Factors of the 2019 Annual Report.

Competition in the Natural Gas Industry

The Company competes with other natural gas pipeline companies for customers transporting natural gas into the southern California market on the basis of transportation rates, access to competitively priced supplies of natural gas, and the quality and reliability of transportation services. The Company also competes for storage services with other third-party storage providers, primarily in northern California.

The following descriptions of the Plan Financing Transactions do not purport to be complete and, in the case of the descriptions of the Corp debt financing transactions and the Company debt financing transactions, are subject, and qualified in entirety by reference, to the full text of the New HoldCo Credit Agreements and the New Utility Credit Agreements, as applicable. Forms of the New Utility Credit Agreements and the HoldCo Revolving Credit Agreement are included as Annexes to the applicable commitment letters included as Exhibits 10.1, 10.2 and 10.3 to Corp’s and our Current Report on Form8-K filed with the SEC on May 27, 2020.

Neither we nor Corp can provide any assurance that this offering or the other Plan Financing Transactions will be completed on the terms we or the Corp anticipate, or at all.

The completion of this offering and any other Plan Financing Transactions are not conditioned upon one another. However, the release of the proceeds of this offering from escrow is conditioned upon the waiver or satisfaction of the Escrow Conditions, which conditions include the Debtors having obtained funding for the Reorganization. Similarly, the consummation, or release from escrow of the proceeds, of each of the other Plan Financing Transactions is conditioned upon, among other things, the Effective Date, which in turn is conditioned upon the Debtors having obtained funding for the Reorganization.

Utility Debt Financing Transactions

On May 26, 2020, the Company entered into a commitment letter (the “Utility RCF Commitment Letter”) for a revolving credit agreement (the “Utility Revolving Credit Agreement”) consisting of a $3.5 billion revolving credit facility (the “New Utility Revolving Credit Facility”), with both JPMorgan Chase Bank, N.A., and Citibank, N.A. asco-administrative agents, and the lenders from time to time party thereto. We anticipate the proceeds from the Utility Revolving Credit Agreement will be used to fund transactions contemplated under the Plan of Reorganization, for general corporate purposes and to pay fees and expenses incurred in connection therewith. The obligations of the Company under the Utility Revolving Credit Agreement will be secured by the issuance of first mortgage bonds secured by a first lien on substantially all of the Company’s real property and certain tangible personal property related to the Company’s facilities, subject to certain exceptions, and will rank pari passu with the New Utility First Mortgage Bonds, and the New Utility Term Loan Credit Agreement (as defined below). The maturity date for the New Utility Revolving Credit Facility will be three years after the effective date of the Utility Revolving Credit Agreement, subject to two1-year extensions, subject to the terms contained in the Utility Revolving Credit Agreement. Subject to the satisfaction or waiver of the conditions contained in the Utility RCF Commitment Letter and the Utility Revolving Credit Agreement, the Utility Revolving Credit Agreement will become effective on the Effective Date.

On May 26, 2020, the Company entered into a commitment letter (the “Utility TL Commitment Letter”) for an up to $6.0 billion term loan credit agreement (the “New Utility Term Loan Credit Agreement” and, together with the Utility Revolving Credit Agreement, the “New Utility Credit Agreements”) consisting of (i) an up to $4.5 billion364-day term loan facility (the “New Utility364-Day Term Loan Facility”) and (ii) an up to $1.5 billion18-month term loan facility (the “New Utility18-Month Term Loan Facility”), with JPMorgan Chase Bank, N.A., as the administrative agent, and the lenders from time to time party thereto. To the extent we raise more than $5.925 billion in this offering, the commitments under the New Utility 364 Day Term Loan Facility will be reduced by such amount. We anticipate the proceeds from the New Utility Term Loan Credit Agreement will be used to, among other things, satisfy certain costs and payments required to be paid under the Plan of Reorganization and to pay fees and expenses incurred in connection therewith. The obligations of the Company under the New Utility Term Loan Credit Agreement will be secured by the issuance of first mortgage bonds secured by a first lien on substantially all of the Company’s real property and certain tangible personal property related to the Company’s facilities, subject to certain exceptions, and will rank pari passu with the New Utility First Mortgage Bonds and the New Utility Revolving Credit Facility. The maturity date for the New Utility364-Day Term Loan Facility will be 364 days after the effective date of the New Utility Term Loan Credit Agreement, and the maturity date for the New Utility18-Month Term Loan Facility will be eighteen months after the effective date of the New Utility Term Loan Credit Agreement. Subject to the satisfaction or waiver of the conditions contained in the Utility TL Commitment Letter and the New Utility Term Loan Credit Agreement, the New Utility Term Loan Credit Agreement will become effective on the Effective Date.

The foregoing description does not purport to be complete and is subject, and qualified in entirety by reference, to the full text of the New Utility Credit Agreements, forms of which are included as Annexes to the applicable commitment letters included as Exhibits 10.1 and 10.2 to Corp’s and our Current Report on Form8-K filed with the SEC on May 27, 2020. See “Description of Other Indebtedness and Preferred Stock” for more information.

Corp Equity Financing Transactions

Corp expects to raise an aggregate of $9.0 billion of gross proceeds in cash the PIPE Transaction and the issuance of shares of common stock, or other equity and/or equity-linked securities of Corp prior to, or substantially concurrently with, the Effective Date.

On or about March 4, 2020, Corp entered into the Equity Backstop Commitment Letters with the Backstop Parties. The Equity Backstop Commitment Letters provide that, under certain circumstances, Corp will issue new

S-50

shares of its common stock for up to $9.0 billion of proceeds to finance the transactions contemplated by the Plan of Reorganization through one or more equity offerings. The structure, terms and conditions of any such equity offering are expected to be determined by Corp prior to the Effective Date, subject to the terms and conditions of the Equity Backstop Commitment Letters. This may include terms and conditions that are designed to preserve the ability of Corp or the Company to utilize their net operating loss carryforwards. There can be no assurance that any such equity offering will be successful. In the event that such equity offerings (together with additional permitted capital sources) do not raise at least $9.0 billion of aggregate proceeds or if Corp does not otherwise consummate such offerings, Corp expects to draw on the backstop commitments contemplated by the Equity Backstop Commitment Letters, pursuant to which the Backstop Parties have severally agreed, subject to certain terms and conditions, to purchase an aggregate amount of shares of Corp’s common stock equal to such shortfall at the Backstop Price (as defined below). On March 16, 2020, the Bankruptcy Court entered an order approving Corp’s entry into and performance under the Equity Backstop Commitment Letters in accordance with the terms and conditions thereof.

As of June 9, 2020, Corp entered into separate agreements (each, a “Consent Agreement”) with Backstop Parties holding 100% of the commitments under the Equity Backstop Commitment Letters to amend each such Backstop Party’s Equity Backstop Commitment Letter in order to, among other things, provide that Corp may issue common stock (or forward-purchase contracts or other equity-linked securities) to finance the transactions contemplated by the Plan of Reorganization at any price per share, as long as such price per share would exceed the Backstop Price and to provide for certain other arrangements, including, but not limited to, a commitment by each Backstop Party to enter into a prepaid forward contract to purchase its pro rata share of $523 million of equity securities as part of Corp’s proposed underwritten offerings to backstop customary “greenshoe” options granted to the underwriters thereof. In addition, the Consent Agreements provide that Corp would issue to each Backstop Party its pro rata share of 50,000,000 shares of Corp common stock on the Effective Date (the “Additional Backstop Commitment Share Premium”), subject to the conditions set forth in each Consent Agreement. The effectiveness of each Consent Agreement is subject to certain conditions, including that by June 30, 2020, Corp must obtain Bankruptcy Court approval of the Consent Agreements.

The “Backstop Price” is defined as (a) the lesser of (i) 10 and (ii) 10times oneplus the percentage change of the Applicable Utility Index Multiple (as defined in the Equity Backstop Commitment Letters) as measured on November 1, 2019 and the fifth business day prior to the Effective Datetimes (b) Corp consolidated Normalized Estimated Net Income (as defined in the Equity Backstop Commitment Letters) for the estimated year 2021,dividedby (c) the number of fully diluted shares of Corp that will be outstanding on the Effective Date (assuming that all equity is raised by funding the commitments pursuant to the Equity Backstop Commitment Letters).

On the Effective Date, Corp expects to issue 119,000,000 shares of common stock to the Backstop Parties (the “Backstop Premium Share Issuance”) as consideration for their obligations under the Equity Backstop Commitment Letters pursuant to an exemption from registration under the Securities Act of 1933, as amended (the “Securities Act”). In the event the market value of those 119,000,000 shares would be less than $764 million based on the weighted average price per share of our common stock for the 20 business days immediately following the Effective Date, the Backstop Parties will receive additional shares so that they receive at least $764 million of aggregate value, subject to a cap of 19,909,091 additional shares in total. Assuming that Bankruptcy Court approval of the Consent Agreements is obtained by June 30, 2020, Corp expects to issue the Additional Backstop Commitment Share Premium as part of the Backstop Premium Shares Issuance.

This description of the Equity Backstop Commitment Letters and the Consent Agreements does not purport to be complete and is subject, and qualified in entirety by reference, to the full text of (i) the Equity Backstop Commitment Letters, the form of which is included as Exhibit 10.1 to Corp’s Current Report on Form8-K filed with the SEC on March 10, 2020, and (ii) the Consent Agreements, the form of which is included as Exhibit 10.1 to Corp’s Current Report on Form8-K filed with the SEC on June 8, 2020.

Corp Debt Financing Transactions

Concurrently with this offering, Corp launched the concurrent notes offering. The net proceeds of the notes offering, together with additional amounts necessary to fund a redemption of the notes offered thereby, will be placed in an escrow account (the “Corp Escrow Account”) established and maintained by The Bank of New York Mellon Trust Company, N.A., as escrow agent, pursuant to an escrow agreement between the Corp and the Escrow Agent (the “Corp Escrow Agreement”) and pledged to The Bank of New York Mellon Trust Company, N.A., as trustee. Pending the satisfaction of the Corp Escrow Conditions (as defined below), the net proceeds will be released to the Corp and used to effectuate the Reorganization.

The Corp Escrow Conditions are as follows: (a) the Confirmation Order (as defined in the next paragraph) shall be in full force and effect and no stay thereof shall be in effect; (b) neither the Plan of Reorganization nor the Confirmation Order shall have been amended or modified or any condition contained therein waived, in either case, in any manner materially adverse to the holders of the notes; (c) all conditions precedent to the effectiveness of the Plan of Reorganization (other than the receipt by Corp of the net proceeds from the offering of the notes) shall have been, or substantially concurrently with the release of the funds held in the Corp Escrow Account, will be, satisfied or waived (to the extent such waiver is not materially adverse to the holders of the notes); (d) we and Corp shall be in compliance in all material respects with the Confirmation Order; (e) all documents necessary to implement the Plan of Reorganization and the financing and distributions contemplated thereunder shall have been executed; (f) (i) the transactions as described and defined in the Plan of Reorganization to occur upon the Effective Date (as defined in the Plan of Reorganization) shall have been consummated; and (ii) we and Corp shall have received the net proceeds from each of such financing transactions; (g) (i) all obligations under the DIP Facilities (as defined in the Plan of Reorganization) (other than contingent obligations not yet due and payable) shall have been paid in full (and all commitments thereunder terminated), or shall be paid in full (and all commitments thereunder terminated) substantially concurrently with the release of the funds held in the Corp Escrow Account, and (ii) all liens related thereto shall have been extinguished, terminated or otherwise released or shall be extinguished, terminated or otherwise released substantially concurrently with the release of the funds held in the Corp Escrow Account; and (h) the pledge agreement required to create the liens in the collateral securing the notes will be executed and delivered (to the extent such document is required to be delivered on such date) along with legal opinions in respect to the pledge agreement and the delivery to the collateral agent of the certificate representing the pledged equity together with an undated stock or similar power executed in blank.

For purposes of the above paragraph:

• “Confirmation Order” means, collectively, (i) the Funding Transactions Order and (ii) the confirmation order entered by the Bankruptcy Court confirming the Plan of Reorganization and approving the transactions contemplated thereby (provided that such order shall be in the form filed by Corp and the Company with the Bankruptcy Court on June 14, 2020, except for any changes thereto that are not materially adverse to the holders of the notes); and

• “Plan of Reorganization” means the Debtors’ and Shareholder Proponents’ Joint Chapter 11 Plan of Reorganization dated December 12, 2019 (as amended on January 31, 2020, March 9, 2020, March 16, 2020, May 22, 2020 and as may be further amended, modified or supplemented from time to time) in the form confirmed by the Bankruptcy Court pursuant to the Confirmation Order (provided that such plan shall be in the form filed by Corp and the Company with the Bankruptcy Court on June 14, 2020, except for any changes thereto that are not materially adverse to the holders of the notes).

“Funding Transactions Order” means the order of the Bankruptcy Court approving the Plan Financing Transactions entered on June 11, 2020 [Docket No. 7909].

If the Corp Escrow Conditions are not satisfied prior to the consummation of the concurrent notes offering, the aggregate net proceeds of such offering, together with additional amounts sufficient to fund the redemption of

S-52

all the notes at 101% of their principal amount of the notes offered thereby, plus accrued and unpaid interest, to, but not including, September 14, 2020 will be deposited into a segregated escrow account that will be pledged for the benefit of the holders of the notes.

On May 26, 2020, Corp entered into a commitment letter (the “Holdco RCF Commitment Letter” and together with the Utility RCF Commitment Letter and the Utility TL Commitment Letter, the “Permanent Debt Commitment Letters”) for a senior secured revolving credit agreement (the “HoldCo Revolving Credit Agreement”) consisting of a $500.0 million revolving credit facility (the “New HoldCo Revolving Credit Facility”), with JPMorgan Chase Bank, N.A., as the administrative agent and collateral agent, and the lenders from time to time party thereto. We anticipate the proceeds from the HoldCo Revolving Credit Agreement will be used for general corporate purposes and to pay fees and expenses incurred in connection therewith. The obligations of Corp under the HoldCo Revolving Credit Agreement will be secured by the pledge of Corp’s ownership interest in 100% of the shares of our common stock on apari passu basis with the notes and the New HoldCo Term Loan Credit Agreement, but will havefirst-out payment priority in accordance with the collateral documents. The maturity date for the New HoldCo Revolving Credit Facility will be three years after the effective date of the HoldCo Revolving Credit Agreement, subject to two1-year extensions, subject to the terms contained in the HoldCo Revolving Credit Agreement. Subject to the satisfaction of the conditions contained in the Holdco RCF Commitment Letter and the HoldCo Revolving Credit Agreement, the HoldCo Revolving Credit Agreement will become effective on the Effective Date.

Corp also expects to enter into a senior secured term loan credit agreement (the “New HoldCo Term Loan Credit Agreement” and, together with the HoldCo Revolving Credit Agreement, the “New HoldCo Credit Agreements” and, the New HoldCo Credit Agreements, together with the New Utility Credit Agreements, the “Credit Facility Transactions”) consisting of a $1.0 billion term loan facility (the “New HoldCo Term Loan Facility”), with JPMorgan Chase Bank, N.A., as the administrative agent and collateral agent, and the lenders from time to time party thereto. To the extent the amount of senior secured notes issued pursuant to the concurrent notes offering is more or less than $3.75 billion, the amount of borrowings pursuant to the New HoldCo Term Loan Facility at the Effective Date would be reduced or increased, respectively, by a corresponding amount. We anticipate the proceeds from the New HoldCo Term Loan Credit Agreement will be used to fund certain transactions under the Plan of Reorganization and to pay fees and expenses incurred in connection therewith. The obligations of Corp under the New HoldCo Term Loan Credit Agreement will be secured by the pledge of Corp’s ownership interest in 100% of the shares of our common stock on apari passu basis with the notes offered in the concurrent notes offering and the New HoldCo Revolving Credit Facility (except that the obligations under the New HoldCo Revolving Credit Facility will havefirst-out payment priority in accordance with the collateral documents). The maturity date for the New HoldCo Term Loan Facility is five years after the date of execution of the New HoldCo Term Loan Credit Agreement. The net proceeds of the HoldCo Term Loan Credit Agreement are expected to be placed in an escrow account (the “HoldCo Term Loan Escrow Account”) which account will be pledged to the collateral agent under the New HoldCo Term Loan Facility. Pending the satisfaction of the escrow conditions (which are substantially the same as the Escrow Conditions) and the release from escrow, the net proceeds will be invested in Permitted Investments.

The foregoing description does not purport to be complete and is subject, and qualified in entirety by reference, to the full text of the New HoldCo Credit Agreements. A form of the HoldCo Revolving Credit Agreement is included as an Annex to the commitment letter included as Exhibit 10.3 to Corp’s and our Current Report on Form8-K filed with the SEC on May 27, 2020. See “Description of Other Indebtedness and Preferred Stock” for more information.

S-53

USA, Goldman Sachs Lending Partners LLC and any other commitment parties that may become parties to the Debt Backstop Commitment Letters as additional “Commitment Parties” as provided therein (the foregoing parties, collectively, the “Commitment Parties”), which were subsequently amended on November 18, 2019, December 20, 2019, January 30, 2020, February 14, 2020 and February 28, 2020, pursuant to which the Commitment Parties committed to provide $10.825 billion in bridge financing in the form of (i) the $5.825 billion Utility Bridge Facility with the Company or any domestic entity formed to hold all of the assets of the Company upon emergence from the Chapter 11 Cases (the Company or any such entity, the “Utility Borrower”) as borrower thereunder and (ii) the $5.0 billion HoldCo Bridge Facility with Corp or any domestic entity formed to hold all of the assets of the Corp upon emergence from the Chapter 11 Cases (Corp or any such entity, the “HoldCo Borrower”) as borrower thereunder, subject to the terms and conditions set forth therein. The commitments under the Debt Backstop Commitment Letters will expire on August 29, 2020, unless terminated earlier pursuant to the termination rights described below. On March 16, 2020, the Bankruptcy Court entered an order approving the Debtors’ entry into and performance under the Debt Backstop Commitment Letters in accordance with the terms and conditions thereof.

Borrowings under the Utility Bridge Facility would be senior secured obligations of the Utility Borrower, secured by substantially all of the assets of the Utility Borrower. Borrowings under the HoldCo Bridge Facility would be senior unsecured obligations of the HoldCo Borrower. The Utility Borrower’s obligations under the Utility Bridge Facility, and the HoldCo Borrower’s obligations under the HoldCo Bridge Facility, would not be guaranteed by any other entity. The scheduled maturity of each of the Bridge Facilities would be 364 days following the date the Bridge Facilities are funded. The Debtors will pay customary fees and expenses in connection with obtaining the Bridge Facilities.

The Commitment Parties’ funding obligations under the Debt Backstop Commitment Letters are subject to numerous conditions and termination rights, including, among others, certain conditions and termination rights similar to those included in the Equity Backstop Commitment Letters, in addition to conditions that are not in the Equity Backstop Commitment Letters, including (i) the delivery of specified financial information, (ii) Corp’s receipt of at least $9.0 billion of proceeds from the issuance of equity, (iii) the execution of definitive documentation for the Bridge Facilities and (iv) that we shall have received investment grade senior secured debt ratings.

In lieu of entering into the Bridge Facilities, the Debtors intend to obtain permanent financing on or prior to the Effective Date pursuant to the Plan Financing Transactions. The financing commitments under the Utility Bridge Facility will be reduced by the aggregate gross proceeds of the mortgage bonds offered hereby, and the financing commitments under the Corp Bridge Facility will be reduced by the gross proceeds of the senior secured notes offered in the concurrent notes offering and the New HoldCo Term Loan Credit Agreement.

The foregoing description of the Debt Backstop Commitment Letters does not purport to be complete and is qualified in its entirety by reference to the Debt Backstop Commitment Letters and amendments, which are included as exhibits to Corp’s and the Company’s Current Report on Form8-K filed with the SEC on October 15, 2019 and on January 27, 2020.

See “Restructuring Support Agreement with the TCC” in Note 14 of the 2019 Annual Report for more information. In connection with this issuance, Corp will enter into a registration rights agreement with Justice John K. Trotter (Ret.), solely in his capacity as trustee of the Fire Victim Trust, the form of which is included as Exhibit 99.1 to PG&E Corporation’s and the Company’s Current Report on Form 8-K filed with the SEC on June 12, 2020.

Participation in Wildfire Fund under AB 1054

State law AB 1054 provides for the establishment of the Wildfire Fund, which will be available for eligible electric utility companies to pay eligible claims for liabilities arising from wildfires occurring after July 12, 2019 that are caused by the applicable electric utility company’s equipment. Electric utility companies that draw from the Wildfire Fund will only be required to repay amounts that are determined by the CPUC in an application for cost recovery not to be just and reasonable, subject to a rolling three-year disallowance cap equal to 20% of the electric utility company’s transmission and distribution equity rate base. The disallowance cap is inapplicable in certain circumstances, including if the Wildfire Fund administrator determines that the electric utility company’s actions or inactions that resulted in the applicable wildfire constituted “conscious or willful disregard of the rights and safety of others,” or the electric utility company fails to maintain a valid safety certification. Costs that the CPUC determines to be just and reasonable will not need to be repaid to the Wildfire Fund, resulting in a draw-down of the Wildfire Fund. The Wildfire Fund and disallowance cap will be terminated when the amounts therein are exhausted. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Legislative And Regulatory Initiatives—Assembly Bill 1054” of the 2019 Annual Report for more information.

We will be required to pay our share of the initial contribution to the Wildfire Fund upon emergence from the Chapter 11 Cases, consisting of an initial contribution of approximately $4,800 million and an initial annual contribution of approximately $193 million. Once we emerge from bankruptcy and make our initial contribution, the Wildfire Fund will be available to us to pay for eligible claims arising between July 12, 2019, the effective date of AB 1054, and our emergence from the Chapter 11 Cases, subject to a limit of 40% of the amount of such claims. The balance of any such claims would need to be paid by us. In addition, we expect our disallowance cap to be approximately $2.4 billion for the three-year period starting in 2019, subject to adjustment based on changes in our total transmission and distribution equity rate base.

Satisfaction of HoldCo Rescission or Damage Claims and Subordinated Debt Claims

Claims against Corp and the Company relating to three purported securities class actions that have been consolidated and denominatedIn re PG&E Corporation SecuritiesLitigation, U.S. District Court for the

S-56

Northern District of California, CaseNo. 18-035509 (the “Securities Action”), will be resolved pursuant to the Plan of Reorganization. These claims consist ofpre-petition claims under the Federal securities laws related to, among other things, allegedly misleading statements or omissions with respect to vegetation management and wildfire safety disclosures, and fall into two categories, each of which is subject to subordination under the Bankruptcy Code. The first category of claims consists ofpre-petition claims arising from or related to the common stock of Corp (such claims, with certain other similar claims against Corp, the “HoldCo Rescission or Damage Claims”). The second category ofpre-petition claims consists of claims arising from debt securities issued by Corp and the Company (such claims, with certain other similar claims against Corp and the Utility, the “Subordinated Debt Claims”, and together with the HoldCo Rescission or Damage Claims, the “Subordinated Claims”).

The total asserted amount of Subordinated Claims filed in the Bankruptcy Court on or before May 27, 2020 (the first date of the Confirmation Hearing) consisted of:

• approximately $2.3 billion of asserted HoldCo Rescission or Damage Claims based solely on holdings of Corp common stock;

• approximately $4.1 billion of asserted Subordinated Debt Claims based solely on holdings of debt securities; and

• approximately $1.9 billion of asserted Subordinated Claims based on holdings of common stock and debt securities (without disaggregating the amounts asserted between Subordinated Claims based on common stock and those based on debt securities).

These amounts include potentially duplicate and/or overstated Subordinated Claims, as well as claims filed after the applicable claims bar date. In addition, these amounts do not reflect unliquidated claims for which no claim amount was asserted. As a result, the amounts of asserted Subordinated Claims identified above may not accurately reflect the amount of claims that will be allowed, and there can be no assurance that the amount of allowed Subordinated Claims will not exceed the amounts identified above.

While we believe we have defenses to the Subordinated Claims, as well as insurance coverage that may be available in respect of the Subordinated Claims, these defenses may not prevail and any such insurance coverage may not be adequate to cover the full amount of the allowed claims. In that case, we will be required, pursuant to the Plan of Reorganization, to satisfy such claims as follows:

• if the Bankruptcy Court approves the treatment to satisfy such claims proposed in the Plan of Reorganization, each holder of an allowed HoldCo Rescission or Damage Claim will receive a number of shares of common stock of Corp equal to such holder’s HoldCo Rescission or Damage Claim Share (as defined below) of the outstanding number of shares of common stock of Corp as of the Petition Date (i.e., 526,118,408 shares). That treatment was objected to in connection with the hearing in the Bankruptcy Court on confirmation of the Plan of Reorganization. The Bankruptcy Court has not yet ruled on that objection, and there can be no guarantee that the Bankruptcy Court will approve such treatment. If the Bankruptcy Court does not approve such treatment it may require a different treatment, which at this time is not known; and

• each holder of an allowed Subordinated Debt Claim will receive payment in full in cash.

“HoldCo Rescission or Damage Claim Share” means a percentage equal to (a) the dollar amount of a holder’s allowed HoldCo Rescission or Damage Claimless any cash payments received from an insurance policy of the Debtors,divided by (b) $35,905,153,932 (representing Corp’s market capitalization calculated using the market opening price on October 12, 2017, the day of the first purported corrective disclosure alleged by the plaintiffs in the Securities Action, and the fully diluted shares outstanding on or around such date).

Corp and the Company currently are engaged in mediation with respect to the Subordinated Claims. If the Subordinated Claims are not resolved pursuant to the mediation (with any such resolution being subject to the

S-57

approval of the Bankruptcy Court), Corp and the Company expect that the Subordinated Claims will be resolved by the Bankruptcy Court in the claims reconciliation process following the Plan of Reorganization Effective Date and treated as described above under the Plan of Reorganization. Under the Plan of Reorganization, after the Effective Date, the Reorganized Debtors have the authority to compromise, settle, object to, or otherwise resolve proofs of claim, and the Bankruptcy Court retains jurisdiction to hear disputes arising in connection with disputed claims. With respect to the Subordinated Claims, the claims reconciliation process may include litigation of the merits of such claims, including the filing of motions, fact discovery, and expert discovery. As a result, the total number and amount of allowed Subordinated Claims may not be determined at the Effective Date. To the extent any such claims are allowed, the total amount of such claims could be material, and therefore could result in (a) the issuance of a material number of shares of common stock of Corp with respect to allowed HoldCo Rescission or Damage Claims regardless of the ultimate treatment of such claims under the Plan of Reorganization, and (b) the payment of a material amount of cash with respect to allowed Subordinated Debt Claims. There can be no assurance that such claims will not have a material adverse impact on our business, financial condition and results of operations.

Further, if shares are issued in respect of allowed HoldCo Rescission or Damage Claims, it may be determined that under the Plan of Reorganization, the Fire Victim Trust should receive additional shares of common stock of PG&E Corporation (assuming, for this purpose, that shares issued in respect of the HoldCo Rescission or Damage Claims were issued on the Effective Date).

Corporate Governance Changes

As part of the Chapter 11 Cases, Corp and the Company committed to a substantial change in the makeup of the Boards of Directors. On June 10, 2020, in connection with its expected emergence from Chapter 11, Corp announced the selection of a new Board of Directors upon emergence to help guide the company post-bankruptcy. The new Board of Directors of Corp will consist of 14 members, 11 of whom are new. It is expected that the Board of Directors of the Company will largely be the same as Corp, with the Chief Executive Officer of the Company serving as an additional member.

As part of the Chapter 11 Cases, pursuant to the CPUC’s decision approving the Plan of Reorganization with conditions and modifications, Corp and the Company have committed to certain changes to their corporate governance. Certain of the changes will be evidenced by amendments to the articles of incorporation, bylaws, corporate governance guidelines, certain committee charters, and other documents, and are expected to become effective by the Effective Date. The principal changes include:

• the Board of Directors of each of Corp and the Company will become classified as follows:

• one class is expected to serve an initial term to expire in 2021, with subsequent terms expiring in 2023, after which terms for this class will revert toone-year terms; and

• the other class is expected to serve an initial term to expire in 2022, with subsequent terms expiring in 2024, after which there will no longer be a classified Board of Directors and all directors will serveone-year terms;

• the Board of Directors of PG&E Corporation will consist of nine to fifteen directors until December 31, 2020 and twelve to fifteen directors thereafter, and the Board of Directors of the Utility will consist of nine to sixteen directors until December 31, 2020 and twelve to sixteen directors thereafter;

• all of the directors, aside from the Chief Executive Officers of each of Corp and the Company, will be “independent” (as defined under the rules and regulations of the New York Stock Exchange and the SEC);

• the evaluation criteria for candidates for the Board of Directors of Corp and the Company will be expanded to include enhanced safety expertise, including a requirement that the Chair of the Board of the Company and members of the Safety and Nuclear Oversight Committees meet one or more designated safety expertise criteria;

S-58

• there will be an executive-level Chief Risk Officer and executive-level Chief Safety Officer, who will be required to provide certain risk and safety reports to the CPUC periodically; and

• the Safety and Nuclear Oversight Committees will be granted increased authority and oversight of public and workplace safety programs, and will be required to approve of executive officer candidates prior to appointments of such officers.

S-59

Redemption, Repurchase and Other Rights

None of the 6% Nonredeemable First Preferred Stock, 5.5% Nonredeemable First Preferred Stock and 5% Nonredeemable First Preferred Stock is subject to redemption. The remaining outstanding series of the Utility Reinstated Preferred Stock may be redeemed at our option, at any time or from time to time, at the redemption price fixed for such series of Preferred Stock together with accumulated and unpaid dividends at the rate fixed therefor to and including the date fixed for redemption. None of the Reinstated Utility Preferred Stock is subject to mandatory redemption. None of the Preferred Stock has preemptive rights or conversion rights.

Pending the satisfaction of the Escrow Conditions and the release from the Escrow Account, all amounts deposited in the Escrow Account will be invested in Permitted Investments (as defined under “—Escrow of Net Proceeds; Special Mandatory Redemption”). If the Escrow Conditions are not satisfied on or prior to September 9, 2020 (or, if prior to such date, we determine in our sole discretion that any of the Escrow Conditions cannot be satisfied by such date), the mortgage bonds offered hereby will be subject to a special redemption on the Special Redemption Date. at a redemption price of 101% of the principal amount of the mortgage bonds offered hereby, plus accrued and unpaid interest to, but not including, the Special Redemption Date. See “—Escrow of Net Proceeds; Special Mandatory Redemption.” The amounts deposited in the Escrow Account will be released and applied to pay for any such redemption.

Until the Escrow Conditions are satisfied, the mortgage bonds will be secured by a lien on amounts deposited in the Escrow Account. Following the satisfaction of the Escrow Conditions, including the effectiveness of the Plan of Reorganization, the Mortgage Indenture will constitute a first lien, subject to Permitted Liens (as described below), on substantially all of our real property and certain tangible personal property related to our facilities. The Mortgage Indenture does not limit the amount of debt that we may issue under it. However, we may issue additional first mortgage bonds under the Mortgage Indenture only on the basis of, and to the extent we have available, Property Additions (as described below), retired mortgage bonds and cash. See “—Issuance of Additional First Mortgage Bonds.” The mortgage bonds will be entitled to the benefit of the Mortgage Indenture equally and ratably with all other mortgage bonds issued under the Mortgage Indenture.

Interest

Floating Rate Mortgage Bonds

The floating rate mortgage bonds will bear interest at a variable rate. The interest rate for the floating rate mortgage bonds for a particular interest period will be a per annum rate equal to LIBOR as determined on the applicable interest determination date by the calculation agent appointed by us, which initially will be The Bank of New York Mellon Trust Company, N.A., plus     %. The interest rate on the floating rate mortgage bonds will be reset on the first day of each interest period other than the initial interest period (each an “interest reset date”). Interest on the floating rate mortgage bonds will be payable quarterly on                    ,                     ,                      and                      of each year, beginning                     , 2020. An interest period is the period commencing on an interest payment date (or, in the case of the initial interest period, commencing on                     , 2020) and ending on the day preceding the next interest payment date. The initial interest period is                     , 2020 through                     , 2020.

The interest determination date for an interest period will be the second London Business Day preceding such interest period (the “interest determination date”). The interest determination date for the initial interest period will be                     , 2020. Promptly upon determination, the calculation agent will inform the Mortgage Trustee and us, or in certain circumstances described below, we or our designee (which may be an independent financial advisor or such other designee of ours (any of such entities, a “Designee”)) will inform the Mortgage Trustee, of the interest rate for the next interest period. Absent manifest error, the determination of the interest rate by the calculation agent, or in certain circumstances described below, by us or our Designee, shall be binding and conclusive on the holders of the floating rate mortgage bonds, the Mortgage Trustee and us. For the avoidance of doubt, in no event shall the calculation agent or the Mortgage Trustee be the Designee.

S-66

If any interest payment date (other than the maturity date) falls on a date that is not a Business Day, the payment will be made on the next Business Day, except that if that Business Day is in the immediately succeeding calendar month, the interest payment will be made on the next preceding Business Day, in each case with interest accruing to the applicable interest payment date (as so adjusted). If the maturity date of the floating rate mortgage bonds falls on a day that is not a Business Day, then the related payment of principal and interest will be made on the next day that is a Business Day with the same effect as if made on the date that the payment was first due, and no interest will accrue on the amount so payable for the period from the maturity date. Interest on the floating rate mortgage bonds payable on each interest payment date will be paid to the person in whose name that floating rate mortgage bond is registered as of the close of business on the regular record date for the applicable interest payment date (whether or not a Business Day). If there has been a default in the payment of interest on a series of the floating rate mortgage bonds, the defaulted interest may be paid to the holders of the floating rate mortgage bonds of such series as of a special record date for the payment of such defaulted interest which shall not be more than 30 days and not less than 10 days prior to the date of the proposed payment and not less than 25 days after the receipt by the Mortgage Trustee of the notice of the proposed payment.

In no event shall the calculation agent be responsible for determining any substitute for LIBOR, or for making any adjustments to any alternative benchmark or spread thereon, the business day convention, interest determination dates or any other relevant methodology for calculating any such substitute or successor benchmark. In connection with the foregoing, the calculation agent will be entitled to conclusively rely on any determinations made by us or our Designee and will have no liability for such actions taken at the direction of ours.

Any determination, decision or election that may be made by the us or our Designee in connection with a Benchmark Transition Event or a Benchmark Replacement, including any determination with respect to a rate or adjustment or of the occurrenceor non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection, will be conclusive and binding absent manifest error, may be made in the us or our Designee’s sole discretion, and, notwithstanding anything to the contrary in the transaction documents, will become effective without consent from any other party. None of the Mortgage Trustee or the calculation agent will have any liability for any determination made by or on behalf of us or our Designee in connection with a Benchmark Transition Event or a Benchmark Replacement.

Interest on the floating rate mortgage bonds will be calculated on the basis of the actual number of days in each quarterly interest period and a360-day year.

“LIBOR” will be determined by the calculation agent in accordance with the following provisions:

(1) With respect to any interest determination date, LIBOR will be the rate for deposits in United States dollars having a maturity of three months commencing on the first day of the applicable interest period that appears on Reuters Screen LIBOR01 Page (as hereinafter defined) as of 11:00 a.m., London time, on that interest determination date. If no rate appears, then LIBOR, in respect of that interest determination date, will be determined in accordance with the provisions described in (2) below.

(2) With respect to an interest determination date on which no rate appears on Reuters Screen LIBOR01 Page, as specified in (1) above, the calculation agent will request the principal London offices of each of four major reference banks in the London interbank market (which may include affiliates of the underwriters), as selected by us, to provide the calculation agent with its offered quotation for deposits in United States dollars for the period of three months, commencing on the first day of the applicable interest period, to prime banks in the London interbank market at approximately 11:00 a.m., London time, on that interest determination date and in a principal amount that is representative for a single transaction in United States dollars in that market at that time. If at least two quotations are provided, then LIBOR on that interest determination date will be the arithmetic mean of those quotations. If fewer than two quotations are provided, then LIBOR on the interest determination date will be the arithmetic mean of the rates quoted at approximately 11:00 a.m., in The City of New York, on the

S-67

interest determination date by three major banks in The City of New York (which may include affiliates of the underwriters) selected by us for loans in United States dollars to leading European banks, having a three-month maturity and in a principal amount that is representative for a single transaction in United States dollars in that market at that time; provided that if the banks selected by us are not providing quotations in the manner described by this sentence, LIBOR will be the same as the rate determined for the immediately preceding interest reset date or if there is no immediately preceding interest reset date, LIBOR will be the same as the rate determined for the initial interest period.

“Reuters Screen LIBOR01 Page” means the display designated on page “LIBOR01” on Reuters (or such other page as may replace the LIBOR01 page on that service or any successor service for the purpose of displaying LIBOR for U.S. dollar deposits of major banks).

“London Business Day” means any day on which dealings in United States dollars are transacted on the London interbank market.

Notwithstanding the two foregoing paragraphs, if we or our Designee determine on or prior to the relevant interest determination date that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to the then current Benchmark, then (i) we shall promptly provide notice of such determination to the calculation agent and (ii) the provisions set forth below under the heading “Effect of Benchmark Transition Event” (the “benchmark transition provisions”) will thereafter apply to all determinations, calculations and quotations made or obtained for the purposes of calculating the rate and amount of interest payable on the floating rate mortgage bonds during a relevant interest period. In accordance with the benchmark transition provisions, after a Benchmark Transition Event and its related Benchmark Replacement Date have occurred, the amount of interest that will be payable for each interest period on the floating rate mortgage bonds will be a rate per annum equal to the sum of the Benchmark Replacement and the margin of     %, as determined by us or our Designee.

However, if we or our Designee determine that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to the then-current Benchmark, but for any reason the Benchmark Replacement has not been determined as of the relevant interest determination date, the interest rate for the applicable interest period will be equal to the interest rate on the last interest determination date for the floating rate mortgage bonds, as determined by us or our Designee.

All percentages resulting from any calculation of any interest rate for the floating rate mortgage bonds will be rounded, if necessary, to the nearest one hundred thousandth of a percentage point, with fiveone-millionths of a percentage point being rounded upwards (e.g., 8.986865% (or 0.08986865) being rounded to 8.98687% (or 0.0898687)) and all dollar amounts used in or resulting from such calculations will be rounded to the nearest cent (withone-half cent being rounded upwards).

The interest rate on the floating rate mortgage bonds will in no event be higher than the maximum rate permitted by New York law as the same may be modified by United States laws of general application. Additionally, the interest rate on the floating rate mortgage bonds will in no event be lower than zero.

The calculation agent will, upon the request of any holder of the floating rate mortgage bonds, provide the interest rate then in effect with respect to the floating rate mortgage bonds. All calculations made by the calculation agent in the absence of manifest error will be conclusive for all purposes and binding on us and the holders of the floating rate mortgage bonds.

S-68

Effect of Benchmark Transition Event

Benchmark Replacement

If we or our Designee determine that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred prior to the Reference Time in respect of any determination of the Benchmark on any date, the Benchmark Replacement will replace the then-current Benchmark for all purposes relating to the floating rate mortgage bonds in respect of such determination on such date and all determinations on all subsequent dates.

Benchmark Replacement Conforming Changes

In connection with the implementation of a Benchmark Replacement, we or our Designee will have the right to make Benchmark Replacement Conforming Changes from time to time.

Decisions and Determinations

Any determination, decision, election or calculation that may be made by us or our Designee pursuant to the benchmark transition provisions described herein, including any determination with respect to a tenor, rate or adjustment or of the occurrence ornon-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection, will be conclusive and binding absent manifest error, may be made in our or our Designee’s sole discretion and notwithstanding anything to the contrary in any documentation relating to the floating rate mortgage bonds, shall become effective without consent from the holders of the floating rate mortgage bonds or any other party.

“Comparable Treasury Price” means, with respect to any redemption date and a series of mortgage bonds:

• the average of the Reference Treasury Dealer Quotations for that redemption date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations; or

The redemption price of the mortgage bonds will be calculated assuming a360-day year consisting of twelve30-day months.

We will send notice of any redemption of the mortgage bonds at least 10 days but not more than 60 days before the redemption date to each registered holder of the mortgage bonds to be redeemed.

Unless we default in payment of the redemption price of the mortgage bonds, on and after the redemption date, interest will cease to accrue on the mortgage bonds or portions of the mortgage bonds called for redemption.

We will have the right to provide conditional redemption notices for redemptions that are contingent upon the occurrence or nonoccurrence of an event or condition that cannot be ascertained prior to the time we are required to notify holders of the redemption. A conditional notice may state that if we have not deposited redemption funds with the Mortgage Trustee or a paying agent on or before the redemption date or we have directed the Mortgage Trustee or paying agent not to apply money deposited with it for redemption of mortgage bonds, we will not be required to redeem the mortgage bonds on the redemption date.

If we are redeeming less than all of the mortgage bonds issued under the Mortgage Indenture at any time, in the case of mortgage bonds in certificated form, the Mortgage Trustee will select the mortgage bonds to be redeemed by lot or by such other method as the Mortgage Trustee shall deem fair and reasonable and, in the case of mortgage bonds in global form, DTC will select the mortgage bonds to be redeemed in accordance with its customary policies and procedures. No mortgage bonds of $2,000 or less can be redeemed in part.

Subject to the foregoing and to applicable law (including, without limitation, United States federal securities laws), we or our affiliates may, at any time and from time to time, purchase outstanding mortgage bonds by tender, in the open market or by private agreement.

S-75

Open Market Purchases; Mandatory Redemption; No Sinking Fund

We may at any time and from time to time purchase mortgage bonds in the open market or otherwise. Except as described under “—Escrow of Net Proceeds; Special Mandatory Redemption,” we will not be required to make any mandatory redemption or sinking fund payments with respect to the mortgage bonds.

Escrow of Net Proceeds; Special Mandatory Redemption

If the Escrow Conditions (as defined below) are not satisfied prior to the consummation of the offering of the mortgage bonds, we will enter into an escrow agreement (the “Escrow Agreement”) with the Mortgage Trustee and The Bank of New York Mellon Trust Company, N.A., as escrow agent (the “Escrow Agent”), pursuant to which we will deposit, into an Escrow Account, the net proceeds of the offering of the mortgage bonds, together with additional cash in an aggregate amount sufficient to fund the redemption of all the mortgage bonds at the Special Redemption Price on September 14, 2020. Pending release from escrow, all amounts deposited in the Escrow Account will be invested in Permitted Investments. The Mortgage Trustee will have a first priority security interest in the Escrow Account and all deposits therein to secure the mortgage bonds pending disbursement as described below. The ability of the holders of the mortgage bonds to realize upon such funds or securities held in the Escrow Account may be subject to certain bankruptcy law limitations.

Pursuant to the terms of the Escrow Agreement, the funds held in the Escrow Account will be released to us upon delivery by us to the Escrow Agent and the Mortgage Trustee of an officer’s certificate certifying that, prior to or concurrently with the release of the funds from the Escrow Account, the following conditions (collectively, the “Escrow Conditions”) have been satisfied:

(a) the Confirmation Order shall be in full force and effect and no stay thereof shall be in effect;

(b) neither the Plan of Reorganization nor the Confirmation Order shall have been amended or modified or any condition contained therein waived, in either case, in any manner materially adverse to the holders of the mortgage bonds;

(c) all conditions precedent to the effectiveness of the Plan of Reorganization (other than the receipt by the Company of the net proceeds from the offering of the mortgage bonds hereby) shall have been, or substantially concurrently with the release of the funds held in the Escrow Account, will be, satisfied or waived (to the extent such waiver is not materially adverse to the holders of the mortgage bonds);

(d) the Company and Corp shall be in compliance in all material respects with the Confirmation Order;

(e) all documents necessary to implement the Plan of Reorganization and the financing and distributions contemplated thereunder shall have been executed;

(f)   (i) the transactions as described and defined in the Plan of Reorganization to occur upon the Effective Date (as defined in the Plan of Reorganization) shall have been consummated, or substantially concurrently with the release of the funds held in the Escrow Account will be consummated, including the following:

(A) Corp shall have consummated, or shall consummate substantially concurrently with the release of the funds held in the Escrow Account, one or more public or private offerings (including rights offerings) or private placements of common stock of Corp (including securities exercisable for, exchangeable or convertible into, or purchase contracts to acquire, common stock of Corp), for aggregate gross proceeds of at least $9.0 billion;

(B) Corp (1) shall have entered into, or shall enter into substantially concurrently with the release of the funds held in the Escrow Account, the New HoldCo Credit Agreements, and shall have borrowed, or shall borrow substantially concurrently with the release of the funds held in the Escrow Account, pursuant to the New HoldCo Term Loan Credit Agreement, and (2) shall have consummated, or shall consummate substantially concurrently with the release of the

S-76

funds held in the Escrow Account, one or more public or private offerings of senior secured notes, in an aggregate principal amount, together with the aggregate gross proceeds of borrowings pursuant to clause (1), equal to at least $4.75 billion; and

(C) the Company shall have entered into, or shall enter into substantially concurrently with the release of the funds held in the Escrow Account, the New Utility Credit Agreements, and shall have borrowed, or shall borrow substantially concurrently with the release of the funds held in the Escrow Account, certain amounts pursuant to the New Utility Term Loan Credit Agreement, an aggregate gross amount equal to at least $11.925 billion less the principal amount of the mortgage bonds issued on the Issue Date;

(ii) the Company and Corp shall have received, or shall receive substantially concurrently with the release of the funds held in the Escrow Account, the net proceeds from each of the financing transactions described in clauses (A) through (C) above;

(g)   (i) all obligations under the DIP Facilities (as defined in the Plan of Reorganization) (other than contingent obligations not yet due and payable) shall have been paid in full (and all commitments thereunder terminated), or shall be paid in full (and all commitments thereunder terminated) substantially concurrently with the release of the funds held in the Escrow Account, and (ii) all liens related thereto shall have been extinguished, terminated or otherwise released or shall be extinguished, terminated or otherwise released substantially concurrently with the release of the funds held in the Escrow Account; and

(h)   (i) the Lien Effective Date shall have occurred, or shall occur substantially concurrently with the release of the funds held in the Escrow Account and (ii) the Mortgage Indenture will be in recordable form and in form and substance sufficient to create a valid lien on and security interest in the Mortgaged Property and the Company shall have made arrangements to effect the recordation of duplicate originals thereof in each county in which the Mortgage Property is located.

We refer to the date, if any, when the Escrow Conditions are satisfied as the “Escrow Release Date.”

The Mortgage Indenture will provide that if the Mandatory Redemption Event occurs, then (a) on the Special Redemption Date, we must redeem all the issued and outstanding mortgage bonds of each series at the Special Redemption Price and (b) all mortgage bonds of each series shall become due and payable on the Special Redemption Date, regardless of whether previously called for redemption. We refer to such a redemption as a “Special Mandatory Redemption.” In addition, if at any time we determine in our sole discretion that the Mandatory Redemption Event is reasonably likely to occur, then we, at our option, may redeem all (but not less than all) the mortgage bonds at the Special Redemption Price on the Special Redemption Date. We refer to such a redemption as a “Special Optional Redemption.” The term “Special Redemption” means either of a Special Mandatory Redemption or a Special Optional Redemption. If we are required to redeem all the issued and outstanding mortgage bonds pursuant to a Special Redemption, funds will be released from the Escrow Account to pay the Special Redemption Price for all such mortgage bonds pursuant to such redemption.

If on or prior to the Escrow Release Date, the Escrow Agent receives a written notice from the Mortgage Trustee to the effect that the principal of, and accrued interest on, the mortgage bonds of any series has become immediately due and payable due to the occurrence and continuation of an Event of Default, the Escrow Agent shall deliver to the Mortgage Trustee, on the third Business Day after receipt of such notice, funds from the Escrow Account equal to the principal of, and accrued interest on, the mortgage bonds that have been accelerated, in accordance with the Mortgage Trustee’s instructions.

All restrictive covenants described under “—Lien of the Mortgage Indenture,” “—Consolidation, Merger, Transfer of Mortgaged Property” and “—Additional Covenants” will be applicable to us beginning on the Issue Date.

Lien of the Mortgage Indenture

General

From and after the Lien Effective Date, the Mortgage Indenture will create a first lien, subject to Permitted Liens, on substantially all of our real property and certain tangible personal property related to our facilities. We refer to property that is subject to the lien of the Mortgage Indenture as “Mortgaged Property” and property that is excepted from the lien of the Mortgage Indenture as “Excepted Property.”

The Mortgage Indenture provides that after-acquired property (other than after-acquired property qualifying as Excepted Property) located in the State of California will be subject to the lien of the Mortgage Indenture (subject to Permitted Liens); provided, however, that in the case of a consolidation or merger (whether or not we are the surviving corporation) or the transfer or lease of all or substantially all of the Mortgaged Property, the Mortgage Indenture will not be required to be a lien upon any of the properties then owned or thereafter acquired by the successor corporation except properties acquired from us in or as a result of that transaction, to the extent not constituting Excepted Property, and improvements, extensions and additions to those properties and renewals, replacements and substitutions of or for any part or parts thereof. In addition, after-acquired property may be subject to liens existing or placed thereon at the time of acquisition thereof, including, but not limited to, purchase money liens, and, in certain circumstances, liens attaching to the property prior to the recording or filing of an instrument specifically subjecting the property to the lien of the Mortgage Indenture.

The Mortgage Indenture provides that, from and after the Lien Effective Date, the Mortgage Trustee shall have a lien, prior to the mortgage bonds, on the Mortgaged Property and on all other property and funds held or collected by the Mortgage Trustee, other than property and funds held in trust for the payment of principal, premium, if any, and interest on the mortgage bonds, as security for the payment of the Mortgage Trustee’s reasonable compensation and expenses, and as security for the performance by us of our obligation to indemnify the Mortgage Trustee against certain liabilities.

Without the consent of the holders, we and the Mortgage Trustee may enter into supplemental indentures in order to subject additional property to the lien of the Mortgage Indenture (including property which would otherwise be Excepted Property). This property would thereupon constitute Property Additions (so long as it would otherwise qualify as Property Additions as described below) and be available as a basis for the issuance of additional first mortgage bonds. See “—Issuance of Additional First Mortgage Bonds.”

S-79

“Lien Effective Date” means the date of delivery by the Company to the Trustee of each of the following:

• an officer’s certificate stating that, prior to or concurrently with the Lien Effective Date:

• the Effective Date (as defined in the Plan of Reorganization) has occurred; and

• any further security documents required to create the lien in the Mortgaged Property will be executed and delivered (to the extent any such document is required to be delivered on such date);

• a company order requesting execution and delivery by the Mortgage Trustee of a supplemental indenture (such company order to be accompanied by the documents required by Section 1.04 of the Mortgage Indenture), if deemed necessary or desirable by the Company to effectuate the lien of the Mortgage Indenture, and such other instruments (in form and substance reasonably satisfactory to the Mortgage Trustee) as the Company may deem necessary or desirable to effectuate the lien of the Mortgage Indenture; and

• an officer’s certificate stating that, to the knowledge of the signer, no event of default has occurred and is continuing.

In addition, pursuant to the Mortgage Indenture, the Company must cause the Mortgage Indenture and instruments supplemental thereto (together with accurate and complete legal descriptions of the real property) to be promptly recorded and filed in such manner and in such places, as may be required by law in order to perfect the liens created thereby, within 120 days following the Lien Effective Date, and provide the Mortgage Trustee an opinion stating that the Mortgage Indenture and any instruments supplemental thereto have been so recorded and filed.

Excepted Property

From and after the Lien Effective Date, the Mortgage Indenture will constitute a first lien, subject to Permitted Liens, on substantially all of our real property and certain tangible personal property related to our facilities, located in the State of California, except for the Diablo Canyon nuclear power plant, our corporate offices, certain specified properties as set forth in the Mortgage Indenture and the following Excepted Property (unless otherwise indicated in any applicable prospectus supplement):

provided, however, that Excepted Property shall not include the identifiable proceeds (as that term is defined in the California Commercial Code) of any Mortgaged Property that we have disposed of in violation of the terms of the Mortgage Indenture.

If an event of default occurs under the Mortgage Indenture, certain of the Excepted Property may become subject to the lien of the Mortgage Indenture.

The Mortgage Indenture permits us to create or allow to exist certain “Permitted Liens,” such as mortgages, deeds of trust, pledges, security interests, leases, reservations, restrictions, charges, encumbrances, or other liens on the Mortgaged Property which rank senior to the lien of the Mortgage Indenture.

“Permitted Liens” include:

Any such additional mortgage bonds either shall be fungible with the original mortgage bonds for federal income tax purposes or shall be issued under a different CUSIP.

“Property Additions” generally include any item, unit or element of property which is owned by us and is subject to the lien of the Mortgage Indenture except (with certain exceptions) goodwill, going concern value rights or intangible property, or any property the cost of acquisition or construction of which is properly chargeable to one of our operating expense accounts at the time of such acquisition or construction.

The Mortgage Indenture includes limitations on the issuance of first mortgage bonds against property subject to liens and upon the increase of the amount of any senior liens on Funded Property.

“Funded Property” generally means Mortgaged Property which has been used as the basis for the issuance of first mortgage bonds or as the basis for the release or substitution of Mortgaged Property under the Mortgage Indenture.

“Retired Securities” means, generally, first mortgage bonds which are no longer outstanding under the Mortgage Indenture, which have not been retired by the application of funded cash and which have not been used as the basis for the authentication and delivery of first mortgage bonds, the release of property or the withdrawal of cash.

“Unfunded Property” generally means Mortgaged Property which has not previously been used as the basis for the issuance of first mortgage bonds (not otherwise retired) or as the basis for the release or substitution of Mortgaged Property.

Release of Mortgaged Property

We may release property from the lien of the Mortgage Indenture if we deliver to the Mortgage Trustee cash equal to the Funded Property Basis (as described below) of the property to be released, less any taxes and expenses incidental to any sale, exchange, dedication or other disposition of the property to be released. Any of the following or any combination of the following will be applied as a credit against the cash we will be required to deliver to the Mortgage Trustee:

• the aggregate principal amount of obligations secured by a Purchase Money Lien on the property to be released, subject to certain limitations described below;

• an amount equal to the Net Cost or Net Fair Value to us (whichever is less) of certified Property Additions constituting Unfunded Property after certain deductions and additions, primarily including adjustments to offset property retirements (except that the adjustments need not be made if the Property Additions were acquired, made or constructed within 90 days before our request for release);

• an amount equal toten-sevenths of the aggregate principal amount of first mortgage bonds we would be entitled to issue on the basis of retired first mortgage bonds (with that entitlement being waived by operation of such release); and

• an amount equal toten-sevenths of the aggregate principal amount of first mortgage bonds delivered to the Mortgage Trustee.

For purposes of this subsection, the following terms have the following meaning:

• “Funded Property Basis” generally means the Net Cost of Funded Property or the Net Fair Value to us of the Funded Property at the time it became Funded Property, whichever is less.

• “Net Cost” means, as of the date of calculation, the cost of the property, less, if such property is subject to a senior lien, the lesser of (i) the outstanding principal amount of any senior lien obligations as of the date of calculation or (ii) the cost of the property.

S-85

• “Net Fair Value” means, as of the date of calculation, the fair value of the property, less, if such property is subject to a senior lien, the lesser of (i) the outstanding principal amount of any senior lien obligations as of the date of calculation or (ii) the fair value of the property.

• “Purchase Money Lien” means, generally, a lien on the property being released which is retained by the transferor of such property to secure all or part of its purchase price or granted to one or more other persons in connection with the transfer or release thereof, or granted to or held by a Mortgage Trustee or agent for any such persons, and may include liens which cover property in addition to the property being released and/or which secure additional indebtedness.

We will be permitted to release from the lien of the Mortgage Indenture Unfunded Property without depositing any cash with the Mortgage Trustee or providing any other credits if either (i) the lower of the Net Cost or Net Fair Value to us of all Unfunded Property (excluding the property to be released), after making certain adjustments, is at least zero, or (ii) the lower of the Net Cost or Net Fair Value to us of the Unfunded Property to be released, after making certain adjustments, does not exceed the lower of the Net Cost or Net Fair Value of all property acquired, made or constructed on or after 90 days before our request, after making certain adjustments. If neither (i) or (ii) in the immediately preceding sentence applies, we will be required to deliver a“make-up” amount in cash. We may apply as a credit against the cash we will be required to deliver to the Mortgage Trustee any of the items described under the bullet points in this section.

We also will be permitted to release in a calendar year property up to the lesser of $10 million (increased yearly by the urban CPI) or 3% of the aggregate principal amount of first mortgage bonds then outstanding without complying with the other release provisions in the Mortgage Indenture. However, if, upon reliance on this release provision, we release Funded Property, we are required to deposit with the Mortgage Trustee, by the end of the calendar year, cash equal to 70% of the Funded Property Basis of the property released, net of certain credits.

The Mortgage Indenture provides simplified procedures for the release of property taken by eminent domain, and provides for dispositions of certain obsolete property and grants or surrender of certain rights without any release or consent by the Mortgage Trustee.

The provisions described above permitting the release of property (except property taken by eminent domain) will be operable only if no event of default has occurred and is continuing under the Mortgage Indenture.

Withdrawal of Cash

Unless an event of default has occurred and is continuing and subject to certain limitations, cash held by the Mortgage Trustee may, generally,

• be withdrawn by us (i) to the extent of an amount equal to the Net Cost or Net Fair Value to us (whichever is less) of Property Additions constituting Unfunded Property, after certain deductions and additions, primarily including adjustments to offset retirements (except that these adjustments need not be made if the Property Additions were acquired or made within 90 days before our request for withdrawal) or (ii) in an amount equal toten-sevenths (10/7ths) of the aggregate principal amount of first mortgage bonds that we would be entitled to issue on the basis of retired first mortgage bonds (with the entitlement to that issuance being waived by operation of the withdrawal) or (iii) in an amount equal toten-sevenths (10/7ths) of the aggregate principal amount of any outstanding first mortgage bonds delivered to the Mortgage Trustee; or

• upon our written request, applied to (i) the purchase of first mortgage bonds or (ii) the payment (or provision for payment) at stated maturity of any first mortgage bonds or the redemption (or provision for redemption) of any first mortgage bonds which are redeemable.

S-86

Evidence to be Furnished to the Mortgage Trustee Under the Mortgage Indenture

We will demonstrate compliance with Mortgage Indenture provisions by providing written statements to the Mortgage Trustee from our officers or persons we select. For instance, we may select an engineer to provide a written statement regarding the value of property being certified or released or counsel regarding compliance with the Mortgage Indenture generally. In certain major matters, applicable law requires that an accountant, engineer or other expert must be independent. We must file a certificate each year with respect to our compliance with the conditions and covenants under the Mortgage Indenture.

Consolidation, Merger, Transfer of Mortgaged Property

We may not consolidate with or merge with or into any other Person (as described below) or convey, otherwise transfer or lease all or substantially all of our Mortgaged Property to any Person unless:

• the Person formed by that consolidation or into which we are merged or the Person which acquires by conveyance or other transfer, or which leases, all or substantially all of the Mortgaged Property is a corporation, partnership, limited liability company, association, company, joint stock company or business trust, organized and existing under the laws of the United States, or any state thereof or the District of Columbia;

• that Person executes and delivers to the Mortgage Trustee a supplemental Mortgage Indenture that in the case of a consolidation, merger, conveyance or other transfer, or in the case of a lease if the term thereof extends beyond the last stated maturity of the mortgage bonds then outstanding, contains an assumption by the successor Person of the due and punctual payment of the principal of and premium, if any, and interest, if any, on all mortgage bonds then outstanding and the performance and observance of every covenant and conditions under the Mortgage Indenture to be performed or observed by us;

• that Person executes and delivers to the Mortgage Trustee a supplemental Mortgage Indenture that contains a grant, conveyance, transfer and mortgage by the successor Person confirming the lien of the Mortgage Indenture on the Mortgaged Property and subjecting to the lien all property (other than Excepted Property) thereafter acquired by the successor Person that shall constitute an improvement, extension or addition to the Mortgaged Property or renewal, replacement or substitution of or for any part thereof and, at the election of the successor Person, subjecting to the lien of the Mortgage Indenture the other property, real, personal and mixed, then owned or thereafter acquired by the Person as the person shall specify in its sole discretion;

• in the case of a lease, the lease is made expressly subject to termination by us at any time during the continuance of an event of default and by the purchaser of the property so leased at any sale of the property under the Mortgage Indenture, whether under the power of sale conferred by the Mortgage Indenture or pursuant to judicial proceedings;

• immediately after giving effect to the transaction and treating any indebtedness that becomes our obligation as a result of the transaction as having been incurred by us at the time of the transaction, no default or event of default shall have occurred and be continuing; and

• we have delivered to the Mortgage Trustee an officer’s certificate and an opinion of counsel, each stating that the merger, consolidation, conveyance, lease or transfer, as the case may be, fully complies with all provisions of the Mortgage Indenture; provided, however, that the delivery of the officer’s certificate and opinion of counsel shall not be required with respect to any merger, consolidation, conveyance, transfer or lease between us and any of our wholly-owned subsidiaries.

Notwithstanding the foregoing, we may merge or consolidate with or transfer all or substantially all of our assets to an affiliate that has no significant assets or liabilities and was formed solely for the purpose of changing our jurisdiction of organization or our form of organization or for the purpose of forming a holding company; provided that the amount of our indebtedness is not increased; and provided, further, that the successor assumes all of our obligations under the Mortgage Indenture.

S-87

In the case of a conveyance or other transfer of all or substantially all of the Mortgaged Property to any other Person as contemplated under the Mortgage Indenture, upon the satisfaction of all the conditions described above we (as we would exist without giving effect to the transaction) would be released and discharged from all obligations under the Mortgage Indenture and on the mortgage bonds then outstanding unless we elect to waive the release and discharge.

The meaning of the term “substantially all” has not been definitively established and is likely to be interpreted by reference to applicable state law if and at the time the issue arises and will depend on the facts and circumstances existing at the time.

For purposes of this subsection:

• “Person” means any individual, corporation, limited liability partnership, joint venture, trust or unincorporated organization, or any other entity, whether or not a legal entity, or any Governmental Authority (as defined in the Mortgage Indenture).

Additional Covenants

We have agreed in the Mortgage Indenture, among other things:

• to maintain a place of payment for any series of mortgage bonds; and

• to maintain our corporate existence (subject to the provisions above relating to mergers and consolidations).

Book-Entry Issuance

Global Securities

The mortgage bonds will be represented by one or more global securities that will be deposited with and registered in the name of DTC or its nominee. Thus, we will not issue certificated securities to you for the mortgage bonds, except in the limited circumstances described below. Each global security will be issued to DTC, which will keep a computerized record of its participants whose clients have purchased the mortgage bonds. Each participant will then keep a record of its clients. Unless it is exchanged in whole or in part for a certificated security, a global security may not be transferred. DTC, its nominees and their successors may, however, transfer a global security as a whole to one another, and these transfers are required to be recorded on our records or a register to be maintained by the Mortgage Trustee. The laws of some jurisdictions may require that certain purchasers of securities take physical delivery of such securities in definitive form. Such limits and laws may impair the ability to transfer or pledge beneficial interests in the global securities.

Beneficial interests in a global security will be shown on, and transfers of beneficial interests in the global security will be made only through, records maintained by DTC and its participants. DTC has provided us with the following information: DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the United States Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered under the provisions of Section 17A of the Exchange Act of 1934, as amended. DTC holds securities that its direct participants deposit with DTC. DTC also records the settlements among direct participants of securities transactions, such as transfers and pledges, in deposited securities through computerized records for direct participants’ accounts. This eliminates the need to exchange certificated securities. Direct participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations, some of whom (and/or their representatives) own DTC.

DTC’s book-entry system is also used by other organizations such as securities brokers and dealers, banks and trust companies that work through a direct participant. The rules that apply to DTC and its participants are on file with the SEC.

S-88

When you purchase mortgage bonds through the DTC system, the purchases must be made by or through a direct participant, which will receive credit for the mortgage bonds on DTC’s records. When you actually purchase the mortgage bonds, you will become their beneficial owner. Your ownership interest will be recorded only on the direct or indirect participants’ records. DTC will have no knowledge of your individual ownership of the mortgage bonds. DTC’s records will show only the identity of the direct participant and the amount of the mortgage bonds held by or through them. You will not receive a written confirmation of your purchase or sale or any periodic account statement directly from DTC. You should instead receive these from your direct or indirect participant. As a result, the direct or indirect participants are responsible for keeping accurate account of the holdings of their customers. The Mortgage Trustee will wire payments on the mortgage bonds to DTC’s nominee. The Mortgage Trustee and we will treat DTC’s nominee as the owner of each global security for all purposes. Accordingly, the Mortgage Trustee, any paying agent and we will have no direct responsibility or liability to pay amounts due on a global security to you or any other beneficial owners in that global security. Any redemption notices will be sent by us directly to DTC, which will, in turn, inform the direct participants (or the indirect participants), which will then contact you as a beneficial holder.

It is DTC’s current practice, upon receipt of any payment of distributions or liquidation amounts, to proportionately credit direct participants’ accounts on the payment date based on their holdings. In addition, it is DTC’s current practice to pass through any consenting or voting rights to such participants by using an omnibus proxy. Those participants will, in turn, make payments to and solicit votes from you, the ultimate owner of mortgage bonds, based on their customary practices. Payments to you will be the responsibility of the participants and not of DTC, the Mortgage Trustee or our company.

Mortgage bonds represented by one or more global securities will be exchangeable for certificated securities with the same terms in authorized denominations only if:

• DTC is unwilling or unable to continue as depositary or ceases to be a clearing agency registered under applicable law, and a successor is not appointed by us within 90 days;

• we decide to discontinue the book-entry system; or

• an event of default has occurred and is continuing with respect to the mortgage bonds.

If the global security is exchanged for certificated securities, the Mortgage Trustee will keep the registration books for the mortgage bonds at its corporate trust office and follow customary practices and procedures regarding those certificated securities.

Clearstream and Euroclear

Links have been established among DTC, Euroclear Bank SA/NV, as operator of the Euroclear System (“Euroclear”) and Clearstream Banking, S.A. (“Clearstream”), which are two European book-entry depositaries similar to DTC, to facilitate the initial issuance of the mortgage bonds sold outside of the United States of America and cross-market transfers of the mortgage bonds associated with secondary market trading.

Although DTC, Clearstream and Euroclear have agreed to the procedures provided below in order to facilitate transfers, they are under no obligation to perform these procedures, and these procedures may be modified or discontinued at any time.

Clearstream and Euroclear will record the ownership interests of their participants in much the same way as DTC, and DTC will record the total ownership of each of the U.S. agents of Clearstream and Euroclear, as participants in DTC.

When mortgage bonds are to be transferred from the account of a DTC participant to the account of a Clearstream participant or a Euroclear participant, the purchaser must send instructions to Clearstream or

S-89

Euroclear through a participant at least one day prior to settlement. Clearstream or Euroclear, as the case may be, will instruct its U.S. agent to receive mortgage bonds against payment. After settlement, Clearstream or Euroclear will credit its participant’s account. Credit for the mortgage bonds will appear on the next day (European time).

Because settlement is taking place during New York business hours, DTC participants will be able to employ their usual procedures for sending mortgage bonds to the relevant U.S. agent acting for the benefit of Clearstream or Euroclear participants. The sale proceeds will be available to the DTC seller on the settlement date. As a result, to the DTC participant, a cross-market transaction will settle no differently than a trade between two DTC participants.

When a Clearstream or Euroclear participant wishes to transfer mortgage bonds to a DTC participant, the seller will be required to send instructions to Clearstream or Euroclear through a participant at least one Business Day prior to settlement. In these cases, Clearstream or Euroclear will instruct its U.S. agent to transfer these mortgage bonds against payment for them. The payment will then be reflected in the account of the Clearstream or Euroclear participant the following day, with the proceeds back-valued to the value date, which would be the preceding day, when settlement occurs in New York. If settlement is not completed on the intended value date, that is, the trade fails, proceeds credited to the Clearstream or Euroclear participant’s account will instead be valued as of the actual settlement date.

UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following discussion summarizes certain material United States (“U.S.”) federal income tax considerations relevant to the purchase, ownership and disposition of the mortgage bonds. This summary only applies to investors who will hold their mortgage bonds as “capital assets” under the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”) and purchase their mortgage bonds for cash upon initial issuance at the “issue price” (the first price at which a substantial amount of the mortgage bonds is sold for money to investors, not including bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers).

This summary is based upon current U.S. federal income tax law, which is subject to change or differing interpretations, possibly with retroactive effect. This summary does not discuss all aspects of U.S. federal income taxation that may be important to particular investors in light of their individual circumstances, such as investors subject to special tax rules (e.g., financial institutions (including banks), insurance companies, expatriates, broker dealers, REITs, regulated investment companies, traders in securities who elect a mark to market method of accounting, tax exempt organizations, persons that will hold the mortgage bonds as a part of a straddle, hedge, conversion, constructive sale or other integrated transaction for U.S. federal income tax purposes, investors subject to section 451(b) of the Internal Revenue Code, entities treated as partnerships for U.S. federal income tax purposes or investors therein, persons subject to alternative minimum tax or U.S. Holders (as defined below) that have a “functional currency” other than the U.S. dollar), all of whom may be subject to tax rules that differ materially from those summarized below. This summary does not discuss all of the aspects of U.S. federal income taxation that may be relevant to you in light of your particular investment or other circumstances. We are not planning to seek a ruling from the Internal Revenue Service (“IRS”) regarding the U.S. federal income tax considerations of the purchase, ownership or disposition of the mortgage bonds. Accordingly, there can be no assurance that the IRS will not successfully challenge one or more of the conclusions stated herein. Each prospective investor is urged to consult its own tax advisor regarding the U.S. federal, state, local and foreign income and other tax considerations of the purchase, ownership or disposition of the mortgage bonds.

For purposes of this summary, a “U.S. Holder” is a beneficial owner of a mortgage bond that is, for U.S. federal income tax purposes, (1) an individual who is a citizen or resident of the United States, (2) a corporation created or organized under the laws of the United States, any state thereof or the District of Columbia, (3) an estate, the income of which is subject to U.S. federal income tax regardless of its source or (4) a trust, if (a) a U.S. court can exercise primary supervision over the administration of the trust and one or more “United States persons” within the meaning of the Internal Revenue Code control all substantial trust decisions or (b) the trust has a valid election in effect under applicable U.S. Treasury regulations to be treated as a United States person. A beneficial owner of a mortgage bond that for U.S. federal income tax purposes is an individual, corporation, estate or trust that is not a U.S. Holder is referred to herein as a“Non-U.S. Holder.”

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes is a beneficial owner of mortgage bonds, the tax treatment of a partner in such partnership generally will depend upon the status of the partner and the activities of such partnership. A partnership considering an investment in the mortgage bonds, and partners in such a partnership, are urged to consult their tax advisors about the U.S. federal income tax considerations of purchasing, owning and disposing of the mortgage bonds.

Certain Additional Payments

In certain circumstances (see “Description of the Mortgage Bonds—Escrow of Net Proceeds; Special Mandatory Redemption”), we may be obligated to pay amounts on the mortgage bonds that are in excess of stated interest or principal on the mortgage bonds. These potential payments may implicate the provisions of the U.S. Treasury regulations relating to “contingent payment debt instruments.” However, we do not intend to treat the possibility of paying such additional amounts as causing the mortgage bonds to be treated as contingent payment debt instruments. Our position is binding on a holder unless such holder discloses its contrary position

S-91

in the manner required by applicable U.S. Treasury regulations. However, our position is not binding on the IRS, and it is possible that the IRS may take a different position, in which case, if the IRS’s position is sustained, a holder might be required to accrue ordinary interest income at a higher rate than the stated interest rate and to treat as ordinary income rather than capital gain any gain recognized on a taxable disposition of a note. The remainder of this discussion assumes that the mortgage bonds will not be treated as contingent payment debt instruments. Prospective investors should consult their tax advisors regarding the possible application of the contingent payment debt instrument rules to the mortgage bonds.

U.S. Holders

Stated interest

It is anticipated, and this discussion assumes, that the mortgage bonds will not be issued with more than a de minimis amount of original issue discount for U.S. federal income tax purposes. Interest on a mortgage bond will generally be taxable to a U.S. Holder as ordinary interest income at the time it is paid or accrued, in accordance with the U.S. Holder’s regular method of tax accounting for U.S. federal income tax purposes.

Sale, exchange, retirement, redemption or other taxable disposition of the mortgage bonds

Upon a sale, exchange, retirement, redemption or other taxable disposition of the mortgage bonds, a U.S. Holder generally will recognize gain or loss in an amount equal to the difference, if any, between the amount realized on the disposition and the U.S. Holder’s adjusted tax basis in such mortgage bonds. The amount realized will include the amount of any cash and the fair market value of any property received for the mortgage bonds (other than any amount attributable to accrued but unpaid interest, which will be taxable as ordinary income (as described above under “Stated interest”) to the extent not previously included in income). A U.S. Holder’s adjusted tax basis in a mortgage bond generally will be equal to the cost of the mortgage bond to such U.S. Holder decreased by any payments received on the mortgage bond other than stated interest. Any such gain or loss generally will be capital gain or loss, and will be long-term capital gain or loss if the U.S. Holder’s holding period for the mortgage bond is more than one year at the time of disposition. Fornon-corporate U.S. Holders, long-term capital gain generally will be subject to reduced rates of taxation. The deductibility of capital losses is subject to certain limitations.

Additional tax on net investment income

The “net investment income” (or undistributed “net investment income,” in the case of a trust or estate) of certain U.S. Holders that are individuals, trusts or estates and that have modified adjusted gross income (or adjusted gross income, in the case of a trust or estate) above a certain threshold is subject to a 3.8% tax, in addition to otherwise applicable U.S. federal income tax. A U.S. Holder’s “net investment income” generally includes, among other things, interest income on and capital gain from the disposition of securities like the mortgage bonds, subject to certain exceptions. U.S. Holders who are individuals, trusts or estates are urged to consult their tax advisors regarding the applicability of this tax to their investment in the mortgage bonds

Non-U.S. Holders

Interest

As discussed above, it is anticipated, and this discussion assumes, that the mortgage bonds will not be issued with more than a de minimis amount of original issue discount. Subject to the discussions below concerning backup withholding and FATCA, all payments of interest on the mortgage bonds made to aNon-U.S. Holder will be exempt from U.S. federal income and withholding tax; provided that: (1) suchNon-U.S. Holder does not own, actually or constructively, 10% or more of the total combined voting power of all classes of stock of the Company entitled to vote, (2) suchNon-U.S. Holder is not a controlled foreign corporation with respect to which the Company is a “related person” (within the meaning of section 864(d)(4) of the Internal Revenue Code),

S-92

(3) the beneficial owner of the mortgage bonds certifies, under penalties of perjury, to us or the paying agent on IRS FormW-8BEN orW-8BEN-E (or appropriate substitute form) that it is not a U.S. person and provides certain other information or satisfies certain other certification requirements and (4) such payments are not effectively connected with suchNon-U.S. Holder’s conduct of a trade or business in the United States.

If aNon-U.S. Holder cannot satisfy the requirements described above, payments of interest will be subject to a 30% U.S. federal withholding tax (or a U.S. federal withholding tax at a lower applicable treaty rate), unless suchNon-U.S. Holder provides us with a properly executed (1) IRS FormW-8BEN orW-8BEN-E (or appropriate substitute form) claiming an exemption from or reduction in withholding under the benefit of an applicable income tax treaty or (2) IRS FormW-8ECI (or appropriate substitute form) stating that interest paid or accrued on the mortgage bonds is not subject to withholding tax because it is effectively connected with the conduct of a trade or business in the United States and is includible in suchNon-U.S. Holder’s gross income.

Sale, exchange, retirement, redemption or other taxable disposition of the mortgage bonds

Subject to the discussion below concerning backup withholding and except with respect to accrued but unpaid interest, which generally will be taxable as interest and may be subject to the rules described above under “—Interest,” aNon-U.S. Holder generally will not be subject to U.S. federal income or withholding tax on the receipt of payments of principal on a mortgage bond, or on any gain recognized upon the sale, exchange, retirement, redemption or other taxable disposition of a mortgage bond, unless in the case of gain (1) such gain is effectively connected with the conduct by suchNon-U.S. Holder of a trade or business within the United States, in which case such gain will be taxed as described below under “Income effectively connected with a U.S. trade or business,” or (2) suchNon-U.S. Holder is an individual who is present in the United States for 183 days or more in the taxable year of disposition, and certain other conditions are met, in which case suchNon-U.S. Holder will be subject to tax at 30% (or, if applicable, a lower treaty rate) on the gain derived from such disposition, which may be offset by U.S. source capital losses.

Income effectively connected with a U.S. trade or business

If aNon-U.S. Holder of mortgage bonds is engaged in a trade or business in the United States, and if interest on the mortgage bonds or gain realized on the sale, exchange, retirement, redemption or other taxable disposition of the mortgage bonds is effectively connected with the conduct of such trade or business, theNon-U.S. Holder generally will be subject to regular U.S. federal income tax on such income or gain in the same manner as if theNon-U.S. Holder were a U.S. Holder. If theNon-U.S. Holder is eligible for the benefits of an income tax treaty between the United States and theNon-U.S. Holder’s country of residence, any “effectively connected” income or gain generally will be subject to U.S. federal income tax only if it is also attributable to a permanent establishment or fixed base maintained by theNon-U.S. Holder in the United States. In addition, if such aNon-U.S. Holder is a foreign corporation, such holder may also be subject to a branch profits tax equal to 30% (or such lower rate provided by an applicable income tax treaty) of its effectively connected earnings and profits, subject to certain adjustments. Payments of interest that are effectively connected with a U.S. trade or business will not be subject to the 30% U.S. federal withholding tax provided that theNon-U.S. Holder claims exemption from withholding. To claim exemption from withholding, theNon-U.S. Holder must certify its qualification, which generally can be done by filing a properly executed IRS FormW-8ECI (or other applicable form).

Information Reporting and Backup Withholding

U.S. Holders

Payments of stated interest on, or the proceeds of the sale, exchange, retirement, redemption or other taxable disposition of, a mortgage bond are generally subject to information reporting unless the U.S. Holder is an exempt recipient (such as a corporation). Such payments may also be subject to U.S. federal backup withholding at a specified rate, currently 24%, if the recipient of such payment fails to supply a taxpayer identification

S-93

number, certified under penalties of perjury, as well as certain other information or otherwise fails to establish an exemption from backup withholding. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a refund or credit against that U.S. Holder’s U.S. federal income tax liability provided the required information is timely furnished to the IRS.

Non-U.S. Holders

ANon-U.S. Holder may be required to comply with certain certification procedures to establish that the holder is not a United States person in order to avoid backup withholding at a specified rate, currently 24%, with respect to payments of stated interest on, or the proceeds of the sale, exchange, retirement, redemption or other taxable disposition of, a mortgage bond. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against thatNon-U.S. Holder’s U.S. federal income tax liability provided the required information is timely furnished to the IRS. In certain circumstances, the name and address of the beneficial owner and the amount of interest paid on a mortgage bond, as well as the amount, if any, withheld, may be reported to the IRS. Copies of these information returns may also be made available under the provisions of a specific treaty or agreement to the tax authorities of the country in which theNon-U.S. Holder resides.

FATCA

Under the Foreign Account Tax Compliance Act provisions of the Internal Revenue Code and related U.S. Treasury guidance (“FATCA”), a U.S. federal withholding tax of 30% will be imposed in certain circumstances on payments of interest on the mortgage bonds. In the case of payments made to a “foreign financial institution” (such as a bank, a broker, an investment fund or, in certain cases, a holding company), as a beneficial owner or as an intermediary, this tax generally will be imposed, subject to certain exceptions, unless such institution (i) has agreed to (and does) comply with the requirements of an agreement with the United States (an “FFI Agreement”) or (ii) is required by (and does comply with) applicable foreign law enacted in connection with an intergovernmental agreement between the United States and a foreign jurisdiction (an “IGA”) to, among other things, collect and provide to the U.S. tax authorities or other relevant tax authorities certain information regarding U.S. account holders of such institution and, in either case, such institution provides the withholding agent with a certification as to its FATCA status. In the case of payments made to a foreign entity that is not a financial institution (as a beneficial owner), the tax generally will be imposed, subject to certain exceptions, unless such entity provides the withholding agent with a certification as to its FATCA status and, in certain cases, identifies any “substantial” U.S. owner (generally, any specified U.S. person that directly or indirectly owns more than a specified percentage of such entity). If a bond is held through a foreign financial institution that has agreed to comply with the requirements of an FFI Agreement or is subject to similar requirements under applicable foreign law enacted in connection with an IGA, such foreign financial institution (or, in certain cases, a person paying amounts to such foreign financial institution) generally will be required, subject to certain exceptions, to withhold tax on payments made to (i) a person (including an individual) that fails to provide any required information or documentation or (ii) a foreign financial institution that has not agreed to comply with the requirements of an FFI Agreement and is not subject to similar requirements under applicable foreign law enacted in connection with an IGA. We will not be obligated to make any “gross up” or additional payments in respect of amounts withheld on the mortgage bonds if we determine that we must so withhold in order to comply with FATCA in respect of the amounts described above. Prospective investors should consult their tax advisors regarding the potential application of withholding under FATCA to their investment in the mortgage bonds

The preceding discussion of U.S. federal tax considerations is for general information only. It is not tax advice. Each prospective investor should consult its own tax advisor regarding the particular U.S. federal, state and local andnon-U.S. tax consequences of purchasing, holding and disposing of our common stock, including the consequences of any proposed change in applicable laws.

The underwriting agreement provides that the obligations of the several underwriters to pay for and accept delivery of the mortgage bonds are subject to certain conditions, including the receipt of legal opinions relating to certain matters. The underwriters must purchase all of the mortgage bonds if they purchase any of the mortgage bonds. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the nondefaulting underwriters may be increased or the underwriting agreement may be terminated.

We have agreed to indemnify the several underwriters against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the underwriters may be required to make in respect of any of these liabilities.

The underwriters are offering the mortgage bonds subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the mortgage bonds, and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of officers’ certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

Commissions and Discounts

The mortgage bonds sold by the underwriters to the public will initially be offered at the prices to the public set forth on the cover of this prospectus supplement and may be offered to certain dealers at these prices less a concession not in excess of (i)    % of the aggregate principal amount of the floating rate mortgage bonds, (ii)    % of the aggregate principal amount of the 2022 mortgage bonds, (iii)    % of the aggregate principal amount of the 2027 mortgage bonds, (iv)    % of the aggregate principal amount of the 2031 mortgage bonds, (v)     % of the aggregate principal amount of the 2040 mortgage bonds or (vi)    % of the aggregate principal amount of the 2050 mortgage bonds. The underwriters may allow, and those dealers may reallow, a discount not in excess of (i)    % of the aggregate principal amount of the floating rate mortgage bonds, (ii)    % of the aggregate principal amount of the 2022 mortgage bonds, (iii)    % of the aggregate principal amount of the 2027 mortgage bonds, (iv)    % of the aggregate principal amount of the 2031 mortgage bonds, (v)    % of the aggregate principal amount of the 2040 mortgage bonds or (vi)    % of the aggregate principal amount of the 2050 mortgage bonds, to certain other dealers. If all of the mortgage bonds are not sold at the prices to the public, the underwriters may change the prices to the public and the other selling terms.

New Issues

Each series of the mortgage bonds will be a new issue of securities with no established trading market. The mortgage bonds will not be listed on any securities exchange or included in any automated quotation system. We have been advised by the underwriters that the underwriters intend to make a market in each series of the mortgage bonds, but they are not obligated to do so and may discontinue market making at any time without notice. No assurance can be given as to the liquidity of any trading markets for the mortgage bonds.

Settlement

It is expected that delivery of the mortgage bonds will be made against payment for the mortgage bonds on or about the date specified on the cover page of this prospectus supplement, which is the                business day following the date of this prospectus supplement (such settlement cycle being referred to as “T+ ”). Under Rule15c6-1 under the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in two business days unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the mortgage bonds prior to the second business day preceding the date of delivery of the mortgage bonds will be required, by virtue of the fact that the mortgage bonds initially will settle in T+    , to specify an alternative settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of the mortgage bonds who wish to trade the mortgage bonds on the date of this prospectus supplement should consult their own advisors.

Price Stabilization and Short Positions

In connection with this offering, the underwriters may engage in transactions that stabilize, maintain, or otherwise affect the prices of the mortgage bonds. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater aggregate principal amount of mortgage bonds than they are required to purchase in this offering. Stabilizing transactions consist of certain bids or purchases made for the purpose of preventing or retarding a decline in the market prices of the mortgage bonds while this offering is in process.

These activities by the underwriters may stabilize, maintain or otherwise affect the market prices of the mortgage bonds. As a result, the prices of the mortgage bonds may be higher than the prices that otherwise might exist in the open market. If these activities are commenced, they may be discontinued by the underwriters at any time. These transactions may be effected in theover-the-counter market or otherwise.

Other Relationships

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. Certain of the underwriters and their respective affiliates have, from time to time, performed, and may in the future perform, various financial advisory and investment banking services for us, for which they received or will receive customary fees and expenses.

In particular, certain of the underwriters or their affiliates, are acting as the underwriters for the offering of senior secured notes by Corp in the concurrent notes offering, will be lenders under the New Utility Credit Agreements and/or the credit agreements to be entered into by Corp in connection with the Reorganization, and may act as underwriters of any offering of equity and/or equity-linked securities by Corp in connection with the Reorganization. In addition, Goldman Sachs & Co. LLC and J.P. Morgan Securities acted as placement agents in connection with the PIPE Transaction. In connection with these transactions, the underwriters or their affiliates have received, and may in the future receive, customary fees, commissions and reimbursement of expenses. Certain of the underwriters and/or their respective affiliates are also providing interim financing to us prior to our emergence from the Chapter 11 Cases, for which these underwriters and/or their respective affiliates are being paid customary fees. These interim financing commitments will be reduced by the aggregate gross proceeds of mortgage bonds issued in this offering upon the closing of this offering. Certain of the underwriters or their affiliates are also lenders under the DIP Facilities.

In the ordinary course of their various business activities, the underwriters and their respective affiliates, officers, directors and employees may purchase, sell or hold a broad array of investments and actively trade securities, derivatives, loans, commodities, currencies, credit default swaps and other financial instruments for their own account and for the accounts of their customers, and such investment and trading activities may involve or relate to assets, securities or instruments of ours (directly, as collateral securing other obligations or otherwise) or persons and entities with relationships with us.

Certain of the underwriters or their affiliates that have a lending relationship with us routinely hedge, and certain other of those underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, such underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the mortgage bonds offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the mortgage bonds offered hereby.

The underwriters and their respective affiliates may also communicate independent investment recommendations, market color or trading ideas or publish or express independent research views in respect of such assets, securities or instruments and may at any time hold, or recommend to clients that they should acquire, long and/or short positions in such assets, securities and instruments.

ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement that PG&E Corporation and Pacific Gas and Electric Company filed with the Securities and Exchange Commission, or the SEC, utilizing a “shelf” registration process. When we refer to the “Utility” in this prospectus, we refer to Pacific Gas and Electric Company, the principal operating subsidiary of PG&E Corporation. When we refer to the “Company,” “we,” “our,” “ours” and “us” in this prospectus under the headings “Forward-Looking Statements” and “Our Company” we mean PG&E Corporation and its subsidiaries, including the Utility, through which substantially all of PG&E Corporation’s operations are conducted. When such terms are used elsewhere in this prospectus, we refer either to PG&E Corporation or the Utility, as the case may be, as the applicable issuer of securities and not to any of their respective direct or indirect subsidiaries or affiliates except as expressly provided. Capitalized terms used in this prospectus and not otherwise defined herein have the meanings given such terms in PG&E Corporation’s and the Utility’s Joint Annual Report on Form10-K for the year ended December 31, 2019, which is incorporated by reference into this prospectus.

Under this shelf registration process, we may from time to time offer and sell securities in one or more offerings up to a total dollar amount of $25,675,000,000 as described in this prospectus.

Each time we offer and sell securities, we will provide a prospectus supplement that contains specific information about the offering and the terms of the offered securities. The prospectus supplement also may add, delete, update or change information contained in this prospectus. You should rely only on the information in the applicable prospectus supplement if this prospectus and the applicable prospectus supplement are inconsistent. Before purchasing any securities, you should carefully read both this prospectus and the applicable prospectus supplement, together with the additional information described under the section of this prospectus titled “Where You Can Find More Information.” In particular, you should carefully consider the risks and uncertainties

i

described under the section titled “Risk Factors” or otherwise included in any applicable prospectus supplement or incorporated by reference in this prospectus before you decide whether to purchase the securities. These risks and uncertainties, together with those not known to us or those that we may deem immaterial, could impair our business and ultimately affect our ability to make payments on the securities.

We do not take any responsibility for, and can provide no assurance as to the reliability of, any information that others may give you. We have not authorized any other person to provide you with information different from the information contained or incorporated by reference in this prospectus and any applicable prospectus supplement. Neither we nor any underwriter, dealer or agent will make an offer to sell the securities in any jurisdiction where the offer or sale is not permitted. You should assume that the information in this prospectus and any applicable prospectus supplement is accurate only as of the dates on their covers and that any information incorporated by reference is accurate only as of the date of the document incorporated by reference, unless we indicate otherwise.

Before making an investment decision, you should carefully consider these risks as well as other information contained or incorporated by reference in this prospectus or the applicable supplement to this prospectus.

Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our business operations, financial results and the value of our securities.

FORWARD-LOOKING STATEMENTS

This prospectus, the documents incorporated by reference in this prospectus and any applicable prospectus supplement contain forward-looking statements that are necessarily subject to various risks and uncertainties. These statements reflect management’s judgment and opinions that are based on current estimates, expectations, and projections about future events and assumptions regarding these events and management’s knowledge of facts as of the date of this prospectus. These forward-looking statements relate to, among other matters, estimated losses, including penalties and fines, associated with various investigations and proceedings; forecasts of capital expenditures; estimates and assumptions used in critical accounting policies, including those relating to liabilities subject to compromise, insurance receivable, regulatory assets and liabilities, environmental remediation, litigation, third-party claims, and other liabilities; and the level of future equity or debt issuances. These statements are also identified by words such as “assume,” “expect,” “intend,” “forecast,” “plan,” “project,” “believe,” “estimate,” “predict,” “anticipate,” “may,” “should,” “would,” “could,” “potential” and similar expressions. We are not able to predict all the factors that may affect future results. Some of the factors that could cause future results to differ materially from those expressed or implied by the forward-looking statements, or from historical results, include, but are not limited to:

• the risks and uncertainties associated with the Chapter 11 Cases, including, but not limited to, the ability to develop, consummate, and implement a plan of reorganization with respect to PG&E Corporation and the Utility that satisfies all applicable legal requirements; the ability to obtain applicable Bankruptcy Court, creditor or state or federal regulatory approvals; the effect of any alternative proposals, views or objections related to the Plan of Reorganization; potential complexities that may arise in connection with concurrent proceedings involving the Bankruptcy Court, the CPUC, and the FERC; increased costs related to the Chapter 11 Cases; the ability to obtain sufficient financing sources for ongoing and future operations and investment; the ability to satisfy the conditions precedent to financing under the Backstop Commitment Letters and the Debt Commitment Letters and the risk that such agreements may be terminated; the risk that the Noteholder RSA, the Subrogation RSA, the TCC RSA or the PSAs could be terminated; disruptions to PG&E Corporation’s and the Utility’s business and operations and the potential impact on regulatory compliance;

1

• whether PG&E Corporation and the Utility will be able to emerge from Chapter 11 by June 30, 2020 with a plan of reorganization that is deemed to meet the requirements of AB 1054, and whether PG&E Corporation and the Utility will need to undertake significant changes in ownership, management and governance in connection therewith;

You should read this prospectus, any applicable prospectus supplements, the documents that we incorporate by reference into this prospectus, the documents that we have included as exhibits to the registration statement of which this prospectus is a part and the documents that we refer to under the section of this prospectus titled “Where You Can Find More Information” completely and with the understanding that our actual future results could be materially different from what we expect when making the forward-looking statement. We qualify all our forward- looking statements by these cautionary statements. These forward-looking statements speak only as of the date of this prospectus, the date of the document incorporated by reference or the date of any applicable prospectus supplement. Except as required by applicable laws or regulations, we do not undertake any obligation to update or revise any forward-looking statement, whether as a result of new information, future events or otherwise.

USE OF PROCEEDS

Each prospectus supplement will describe the uses of the proceeds from the issuance of the securities offered by that prospectus supplement.

DESCRIPTION OF SECURITIES

The following is a general description of the terms and provisions of the securities we may offer and sell by this prospectus. These summaries are not meant to be a complete description of each security. This prospectus and any accompanying prospectus supplement will contain the material terms and conditions for each security. The accompanying prospectus supplement may add, update or change the terms and conditions of the securities as described in this prospectus.

Holding Company Structure

PG&E Corporation conducts its operations primarily through its subsidiaries and substantially all of its consolidated assets are held by its subsidiaries. Accordingly, PG&E Corporation’s cash flow and its ability to meet its obligations under its debt securities are largely dependent upon the earnings and cash flows of its subsidiaries and the distribution or other payment of these earnings and cash flows to PG&E Corporation in the form of dividends or loans or advances and repayment of loans and advances from the Utility. PG&E Corporation’s subsidiaries are separate and distinct legal entities and have no obligation to pay any amounts due on its debt securities or to make any funds available for payment of amounts due on these debt securities.

Because PG&E Corporation is a holding company, its obligations under its debt securities will be structurally subordinated to all existing and future liabilities of its subsidiaries, including all the existing and future liabilities of the Utility. Therefore, the rights of PG&E Corporation and its creditors, including the rights of the holders of its debt securities, to participate in the assets of any subsidiary upon the liquidation or reorganization of the subsidiary will be subject to the prior claims of the subsidiary’s creditors. To the extent that PG&E Corporation is itself a creditor with recognized claims against any of its subsidiaries, its claims would still be effectively subordinated to any security interest in, or mortgages or other liens on, the assets of the subsidiary and would be subordinated to any indebtedness or other liabilities of the subsidiary that are senior to the claims held by PG&E Corporation.

SENIOR NOTES

Set forth below is a description of the general terms of the senior notes, which may be unsecured or secured (“senior notes”). The following description does not purport to be complete and is subject to, and is qualified in its entirety by reference to, (i) the unsecured senior note indenture to be entered into between us and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Unsecured Senior Note Indenture Trustee”), to be supplemented by supplemental indentures establishing the unsecured senior notes of each series and (ii) the secured senior note indenture to be entered into between us and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Secured Senior Note Indenture Trustee,” and together with the Unsecured Senior Note Indenture Trustee, the “Senior Note Indenture Trustees”)), to be supplemented by supplemental indentures establishing the secured senior notes of each series. The unsecured senior note indenture, as amended or supplemented from time to time, is referred to herein as the “Unsecured Senior Note Indenture.” The secured senior note indenture, as amended or supplemented from time to time, is herein referred to as the “Secured Senior Note Indenture,” and together with the Unsecured Senior Note Indenture, the “Senior Note Indentures.”

There will be no requirement under either the Unsecured Senior Note Indenture or the Secured Senior Note Indenture that our future issuances of senior notes be issued exclusively under either indenture. We will be free to employ other indentures or documentation containing provisions different from those included in either indenture or applicable to one or more issuances of unsecured senior notes or secured senior notes, as the case may be, in connection with future issuances of other senior notes.

We have summarized selected provisions of the Senior Note Indentures and the senior notes below. The information we are providing you in this prospectus concerning the senior notes and the Senior Note Indentures is only a summary of the information provided in those documents, and the summary is qualified in its entirety by reference to the provisions of the Senior Note Indentures, including the form of applicable senior notes attached thereto. You should consult the applicable form of the senior notes themselves and the applicable Senior Note Indenture for more complete information on the senior notes as they, and not this prospectus or any applicable prospectus supplement, govern your rights as a holder. The forms of the Senior Note Indentures are included as exhibits to the registration statement of which this prospectus is a part. The terms of the senior notes will include those stated in the Senior Note Indentures and those made a part of the Senior Note Indentures by reference to the Trust Indenture Act of 1939, as amended, or the Trust Indenture Act. Certain capitalized terms used in this prospectus are defined in the applicable Senior Note Indenture.

In this section, references to “we,” “our,” “ours,” “us” and “the Company” refer only to PG&E Corporation and not to any of its direct or indirect subsidiaries or affiliates except as expressly provided.

General

The unsecured senior notes will be issued as unsecured senior debt securities under the Unsecured Senior Note Indenture and will rank equally with all other future unsecured and unsubordinated debt of the Company. The unsecured senior notes will be effectively subordinated to all secured debt of the Company, including the secured senior notes. The secured senior notes will be issued as secured senior debt securities under the Secured Senior Noted Indenture and will rank equally with all other future secured senior notes of the Company. As of December 31, 2019, we had no secured senior notes outstanding under the Secured Senior Note Indenture, and on an unconsolidated basis, we had no secured debt outstanding. As of December 31, 2019, we had no unsecured senior notes outstanding under the Unsecured Senior Note Indenture. Each Senior Note Indenture does not limit the aggregate principal amount of senior notes that may be issued under such Senior Note Indenture and provides that senior notes may be issued from time to time in one or more series pursuant to a supplemental indenture to such Senior Note Indenture. The Senior Note Indentures give us the ability to reopen a previous series of senior notes and issue additional senior notes of such series, unless otherwise provided.

Payment and Paying Agent

Unless otherwise indicated in an applicable prospectus supplement, payment of principal of any senior notes will be made only against surrender to the Paying Agent of such senior notes.

Modification

Each Senior Note Indenture contains provisions permitting us and the applicable Senior Note Indenture Trustee, with the consent of the holders of not less than a majority in principal amount of the outstanding senior notes of each series that is affected, to modify the applicable Senior Note Indenture or the rights of the holders of the senior notes of such series; provided, that no such modification may, without the consent of the holder of each outstanding senior note that is affected:

• change the stated maturity of the principal of, or any installment of principal of or interest on, any senior note, or reduce the principal amount of any senior note or the rate of interest on any senior note or any premium payable upon the redemption of any senior note, or change the method of calculating the rate of interest of any senior note, or impair the right to institute suit for the enforcement of any such payment on or after the stated maturity of any senior note (or, in the case of redemption, on or after the redemption date); or

• reduce the percentage of principal amount of the outstanding senior notes of any series, the consent of whose holders is required for any such supplemental indenture, or the consent of whose holders is required for any waiver (of compliance with certain provisions of the applicable Senior Note Indenture or certain defaults under such Senior Note Indenture and their consequences) provided for in such Senior Note Indenture; or

• modify any of the provisions of the applicable Senior Note Indenture relating to supplemental indentures, waiver of past defaults, or waiver of certain covenants, except to increase any such percentage or to provide that certain other provisions of such Senior Note Indenture cannot be modified or waived without the consent of the holder of each outstanding senior note that is affected.

In addition, we and the applicable Senior Note Indenture Trustee may execute, without the consent of any holders of senior notes, any supplemental indenture for certain other usual purposes, including the creation of any new series of senior notes.

Events of Default

Each Senior Note Indenture provides that any one or more of the following described events with respect to the senior notes of any series, which has occurred and is continuing, constitutes an “Event of Default” with respect to the senior notes of such series:

• failure for 30 days to pay interest on the senior notes of such series, when due on an interest payment date other than at maturity or upon earlier redemption; or

• failure to pay principal or premium, if any, or interest on the senior notes of such series when due at maturity or upon earlier redemption; or

• failure for three Business Days to deposit any sinking fund payment when due by the terms of a senior note of such series; or

10

• failure to observe or perform any other covenant or warranty of ours in the applicable Senior Note Indenture (other than a covenant or warranty which has expressly been included in such Senior Note Indenture solely for the benefit of one or more series of senior notes other than such series) for 90 days after written notice to us from the applicable Senior Note Indenture Trustee or to us and such Senior Note Indenture Trustee from the holders of at least 33% in principal amount of the outstanding senior notes of such series; or

• certain events of bankruptcy, insolvency or reorganization of the Company.

The holders of not less than a majority in aggregate outstanding principal amount of the senior notes of any series have the right to direct the time, method and place of conducting any proceeding for any remedy available to the applicable Senior Note Indenture Trustee with respect to the senior notes of such series. If a Senior Note Indenture Event of Default occurs and is continuing with respect to the senior notes of any series, then the applicable Senior Note Indenture Trustee or the holders of not less than 33% in aggregate outstanding principal amount of the senior notes of such series may declare the principal amount of the senior notes due and payable immediately by notice in writing to us (and to such Senior Note Indenture Trustee if given by the holders), and upon any such declaration such principal amount shall become immediately due and payable; provided, however, that upon the occurrence of an Event of Default specified in the last bullet above, the principal amount of all senior notes of that series then outstanding shall be due and payable immediately without any declaration or other action by such Senior Note Indenture Trustee or the holders of such series. At any time after such a declaration of acceleration with respect to the senior notes of any series has been made and before a judgment or decree for payment of the money due has been obtained as provided in the applicable Senior Note Indenture, the holders of not less than a majority in aggregate outstanding principal amount of the senior notes of such series may rescind and annul such declaration and its consequences if all Events of Default with respect to such senior notes, other than thenon-payment of the principal of such senior notes which has become due solely by such declaration of acceleration, have been cured or waived and the Company has paid or deposited with such Senior Note Indenture Trustee a sum sufficient to pay all overdue interest (including, to the extent such interest is lawful, interest upon overdue interest at the rate or rates prescribed therefor in such senior notes) and principal due otherwise than by acceleration and all sums paid or advanced by such Senior Note Indenture Trustee, including reasonable compensation and expenses of such Senior Note Indenture Trustee.

The holders of not less than a majority in aggregate outstanding principal amount of the senior notes of any series may, on behalf of the holders of all the senior notes of such series, waive any past default with respect to such series, except (i) a default in the payment of principal or interest or (ii) a default in respect of a covenant or provision which under the applicable Senior Note Indenture cannot be modified or amended without the consent of the holder of each outstanding senior note of such series affected.

Satisfaction and Discharge

Any senior note, or any portion of the principal amount thereof, will be deemed to have been paid for purposes of the applicable Senior Note Indenture, and our entire indebtedness in respect of the senior notes will be deemed to have been satisfied and discharged, if certain conditions are satisfied, including an irrevocable deposit with the applicable Senior Note Indenture Trustee or any paying agent (other than us) in trust of:

• money in an amount which will be sufficient; or

• in the case of a deposit made prior to the maturity of the senior notes or portions thereof, Eligible Obligations (as defined below) which do not contain provisions permitting the redemption or other prepayment thereof at the option of the issuer thereof, the principal of and the interest on which when due, without any regard to reinvestment thereof, will provide monies which, together with the money, if any, deposited with or held by such Senior Note Indenture Trustee or the paying agent, will be sufficient; or

• a combination of either of the two items described in the two preceding bullet points which will be sufficient;

11

to pay when due the principal of and premium, if any, and interest, if any, due and to become due on the senior notes or portions thereof.

This discharge of the senior notes through the deposit with the applicable Senior Note Indenture Trustee of cash or Eligible Obligations generally will be treated as a taxable disposition for U.S. federal income tax purposes by the holders of those senior notes. Prospective investors in the senior notes should consult their own tax advisors as to the particular U.S. federal income tax consequences applicable to them in the event of such discharge.

For purposes of this subsection, “Eligible Obligations” for U.S. dollar-denominated senior notes, means securities that are direct obligations of, or obligations unconditionally guaranteed by, the United States, entitled to the benefit of the full faith and credit thereof, or depositary receipts issued by a bank as custodian with respect to these obligations or any specific interest or principal payments due in respect thereof held by the custodian for the account of the holder of a depositary receipt.

The applicable Senior Note Indenture Trustee, prior to an Event of Default with respect to senior notes of any series, undertakes to perform, with respect to senior notes of such series, only such duties as are specifically set forth in such Senior Note Indenture and, in case an Event of Default with respect to senior notes of any series has occurred and is continuing, shall exercise, with respect to senior notes of such series, the same degree of care as a prudent individual would exercise in the conduct of his or her own affairs. Subject to such provision, the applicable Senior Note Indenture Trustee is under no obligation to exercise any of the powers vested in it by such Senior Note Indenture at the request of any holder of senior notes of any series, unless offered reasonable indemnity by such holder against the costs, expenses and liabilities which might be incurred by such Senior Note Indenture Trustee. The applicable Senior Note Indenture Trustee is not required to expend or risk its own funds or otherwise incur any financial liability in the performance of its duties if such Senior Note Indenture Trustee reasonably believes that repayment or adequate indemnity is not reasonably assured to it.

We and certain of our subsidiaries may maintain deposit accounts and banking relationships with the Senior Note Indenture Trustees. The Senior Note Indenture Trustees and certain of their affiliates may also serve as trustee under other indentures pursuant to which securities of the Company and certain subsidiaries of the Company are outstanding.

The applicable Senior Note Indenture Trustee may resign at any time with respect to the senior notes of one or more series upon written notice to us, and such Senior Note Indenture Trustee may be removed at any time by written notice delivered to it and us and signed by the holders of at least a majority in principal amount of outstanding senior notes. No resignation or removal of a Senior Note Indenture Trustee will take effect until a successor trustee accepts appointment. In addition, under certain circumstances, we may remove the applicable Senior Note Indenture Trustee with respect to any series. We must give notice of resignation and removal of the applicable Senior Note Indenture Trustee with respect to a series or the appointment of a successor trustee as provided in the applicable Senior Note Indenture.

Governing Law

The Senior Note Indentures and the senior notes will be governed by, and construed in accordance with, the internal laws of the State of New York.

Miscellaneous

We will have the right at all times to assign any of our rights or obligations under any Senior Note Indenture to a direct or indirect wholly-owned subsidiary; provided, that, in the event of any such assignment, we will

12

remain primarily liable for all such obligations. Subject to the foregoing, the applicable Senior Note Indenture will be binding upon and inure to the benefit of the parties to such Senior Note Indenture and their respective successors and assigns.

SUBORDINATED NOTES

Set forth below is a description of the general terms of the subordinated notes. The following description does not purport to be complete and is subject to, and is qualified in its entirety by reference to, the subordinated note indenture to be entered into between us and a trustee to be named (the “Subordinated Note Indenture Trustee”), to be supplemented by supplemental indentures establishing the subordinated notes of each series. The subordinated note indenture, as amended or supplemented from time to time, is referred to as the “Subordinated Note Indenture.” The form of the Subordinated Note Indenture was filed as Exhibit 4.2 to the Form8-K we filed on March 9, 2009 (FileNo. 001-12609). We have summarized selected provisions of the Subordinated Note Indenture and the subordinated notes below. The information we are providing you in this prospectus concerning the subordinated notes and the Subordinated Note Indenture is only a summary of the information provided in those documents, and the summary is qualified in its entirety by reference to the provisions of the Subordinated Note Indenture, including the form of subordinated notes attached thereto. You should consult the form of the subordinated notes themselves and the Subordinated Note Indenture for more complete information on the subordinated notes as they, and not this prospectus or any applicable prospectus supplement, govern your rights as a holder. The terms of the subordinated notes will include those stated in the Subordinated Note Indenture and those made a part of the Subordinated Note Indenture by reference to the Trust Indenture Act of 1939, as amended, or the Trust Indenture Act. Certain capitalized terms used in this prospectus are defined in the Subordinated Note Indenture.

In this section, references to “we,” “our,” “ours,” “us” and “the Company” refer only to PG&E Corporation and not to any of its direct or indirect subsidiaries or affiliates except as expressly provided.

General

The subordinated notes will be issued as unsecured junior subordinated debt securities under the Subordinated Note Indenture. The Subordinated Note Indenture does not limit the aggregate principal amount of subordinated notes that may be issued under the Subordinated Note Indenture and provides that subordinated notes may be issued from time to time in one or more series pursuant to an indenture supplemental to the Subordinated Note Indenture. The Subordinated Note Indenture gives us the ability to reopen a previous issue of subordinated notes and issue additional subordinated notes of such series, unless otherwise provided.

Provisions of a Particular Series

The prospectus supplement applicable to each series of subordinated notes will specify, among other things:

• the title of such subordinated notes;

• any limit on the aggregate principal amount of such subordinated notes;

• the date or dates on which the principal of such subordinated notes is payable, including the maturity date, or the method or means by which those dates will be determined, and our right, if any, to extend those dates and the duration of any such extension;

• the rate or rates at which such subordinated notes shall bear interest, if any, or any method by which such rate or rates will be determined, the date or dates from which such interest will accrue, the interest payment dates on which such interest shall be payable, the regular record date for the interest payable on any interest payment date, and the right, if any, to extend the interest payment periods and the duration of any such extension;

13

• the place or places where the principal of (and premium, if any) and interest, if any, on such subordinated notes shall be payable, the methods by which registration of the transfer of subordinated notes and exchanges of subordinated notes may be effected, and by which notices and demands to or upon us in respect of such subordinated notes may be made, given, furnished, filed or served;

• the period or periods within which, or date or dates on which, the price or prices at which and the terms and conditions on which the subordinated notes may be redeemed, in whole or in part, at our option, and any restrictions on such redemption;

• our obligation, if any, to redeem, purchase or repay such subordinated notes pursuant to any sinking fund or analogous provisions or at the option of the holder and the terms and conditions upon which the subordinated notes will be so redeemed, purchased or repaid;

• the denominations in which such subordinated notes shall be issuable;

• the currency or currencies in which the principal, premium, if any, and interest on the subordinated notes will be payable if other than U.S. dollars and the method for determining the equivalent amount in U.S. dollars;

• if the amount of payments of principal of (and premium, if any) or interest (including Additional Interest (as defined below)) on such subordinated notes may be determined with reference to an index or formula, the manner in which such amounts shall be determined;

• any deletions from, modifications of or additions to the Events of Default or covenants of the Company as provided in the Subordinated Note Indenture pertaining to such subordinated notes;

• whether such subordinated notes shall be issued in whole or in part in the form of a global security and, if so, the name of the depositary for any global securities; and

• any other terms of such subordinated notes.

The Subordinated Note Indenture does not contain provisions that afford holders of subordinated notes protection in the event of a highly leveraged transaction involving us.

Registration and Transfer

We shall not be required to (i) issue, register the transfer of or exchange subordinated notes of any series during a period of 15 days immediately preceding the date notice is given identifying the subordinated notes of such series called for redemption, or (ii) issue, register the transfer of or exchange any subordinated notes so selected for redemption, in whole or in part, except the unredeemed portion of any subordinated note being redeemed in part.

Payment and Paying Agent

Unless otherwise indicated in an applicable prospectus supplement, payment of principal of any subordinated notes will be made only against surrender to the Paying Agent of such subordinated notes. Principal of and interest on subordinated notes will be payable, subject to any applicable laws and regulations, at the office of such Paying Agent or Paying Agents as we may designate from time to time, except that, at our option, payment of any interest may be made by wire transfer or by check mailed to the address of the person entitled to an interest payment as such address shall appear in the Security Register with respect to the subordinated notes. Payment of interest on subordinated notes on any interest payment date will be made to the person in whose name the subordinated notes (or predecessor security) are registered at the close of business on the record date for such interest payment.

Unless otherwise indicated in an applicable prospectus supplement, the Subordinated Note Indenture Trustee will act as Paying Agent with respect to the subordinated notes. We may at any time designate additional Paying Agents or rescind the designation of any Paying Agents or approve a change in the office through which any Paying Agent acts.

14

All moneys paid by us to a Paying Agent for the payment of the principal of (and premium, if any) or interest on the subordinated notes of any series which remain unclaimed at the end of two years after such principal (and premium, if any) or interest shall have become due and payable will be repaid to us, and the holder of such subordinated notes will from that time forward look only to us for payment of such principal (and premium, if any) and interest.

Consolidation, Merger and Sale

The Company shall not consolidate with or merge into any other corporation or convey, transfer or lease its properties and assets substantially as an entirety to any Person (as defined below), unless:

• in case the Company shall consolidate with or merge into another corporation or convey, transfer or lease its properties and assets substantially as an entirety to any Person, the corporation formed by such consolidation or into which the Company is merged or the Person which acquires by conveyance or transfer, or which leases, the properties and assets of the Company substantially as an entirety shall be a corporation organized and existing under the laws of the United States of America, any State thereof or the District of Columbia and shall expressly assume, by a supplemental indenture to the Subordinated Note Indenture, executed and delivered to the Subordinated Note Indenture Trustee, in form satisfactory to the Subordinated Note Indenture Trustee, the due and punctual payment of the principal of (and premium, if any) and interest (including Additional Interest) on all the subordinated notes and the performance of every covenant of the Subordinated Note Indenture on the part of the Company to be performed or observed;

• immediately after giving effect to such transactions, no Event of Default, and no event which, after notice or lapse of time or both, would become an Event of Default, shall have happened and be continuing; and

• the Company has delivered to the Subordinated Note Indenture Trustee an officer’s certificate and an opinion of counsel, each stating that such consolidation, merger, conveyance, transfer or lease complies with Article Eight of the Subordinated Note Indenture and that all conditions precedent relating to such transaction in the Subordinated Note Indenture have been complied with.

Notwithstanding the foregoing, the Company may merge or consolidate with or transfer all or substantially all of its assets to an affiliate that has no significant assets or liabilities and was formed solely for the purpose of changing the jurisdiction of organization of the Company or the form of organization of the Company; provided that the amount of indebtedness of the Company is not increased thereby; and provided, further that the successor assumes all obligations of the Company under the Subordinated Note Indenture.

The meaning of the term “substantially all” has not been definitively established and is likely to be interpreted by reference to applicable state law if and at the time the issue arises and will depend on the facts and circumstances existing at the time.

For purposes of this subsection, “Person” means any individual, corporation, partnership, limited liability company, joint venture, association, joint-stock company, trust, unincorporated organization or government or any agency or political subdivision thereof.

Subordination

The subordinated notes are subordinated and junior in right of payment to all of our Senior Indebtedness (as defined below). No payment of any principal, including redemption payments, if any, premium, if any, or interest on (including Additional Interest) the subordinated notes shall be made if:

• any Senior Indebtedness is not paid when due whether at the stated maturity of any such payment or by call for redemption and any applicable grace period with respect to such default has ended, with such default remaining uncured and such default has not been waived or otherwise ceased to exist;

15

• the maturity of any Senior Indebtedness has been accelerated because of a default; or

• notice has been given of the exercise of an option to require repayment, mandatory payment or prepayment or otherwise.

Upon any payment or distribution of assets of the Company to creditors upon any liquidation, dissolution,winding-up, reorganization, assignment for the benefit of creditors, marshalling of assets or liabilities, or any bankruptcy, insolvency or similar proceedings of the Company, the holders of Senior Indebtedness shall be entitled to receive payment in full of all amounts due or to become due on or in respect of all Senior Indebtedness before the holders of the subordinated notes are entitled to receive or retain any payment or distribution. Subject to the prior payment of all Senior Indebtedness, the rights of the holders of the subordinated notes will be subrogated to the rights of the holders of Senior Indebtedness to receive payments and distributions applicable to such Senior Indebtedness until all amounts owing on the subordinated notes are paid in full.

For purposes of this subsection, “assets of the Company” shall not be deemed to include shares of stock of the Company as reorganized or readjusted, or securities of the Company or any other corporation provided for by a plan of reorganization or readjustment, the payment of which is subordinated at least to the extent provided in the Subordinated Note Indenture with respect to the subordinated notes to the payment of all Senior Indebtedness that may at the time be outstanding; provided, however, that (i) the Senior Indebtedness is assumed by the new corporation, if any, resulting from any such reorganization or readjustment, and (ii) the rights of the holders of the Senior Indebtedness are not, without the consent of such holders, altered by such reorganization or readjustment. The consolidation of the Company with, or the merger of the Company into, another corporation or the liquidation or dissolution of the Company following the conveyance or transfer of its property as an entirety, or substantially as an entirety, to another corporation upon the terms and conditions provided for in Article Eight of the Subordinated Note Indenture shall not be deemed a dissolution,winding-up, liquidation or reorganization for the purposes of this subsection if such other corporation shall, as a part of such consolidation, merger, conveyance or transfer, comply with the conditions stated in Article Eight of the Subordinated Note Indenture.

The term “Senior Indebtedness” means, with respect to us:

• any payment due in respect of our indebtedness, whether outstanding at the date of execution of the Subordinated Note Indenture or incurred, created or assumed after such date, (a) in respect of money borrowed (including any financial derivative, hedging or futures contract or similar instrument) and (b) evidenced by securities, debentures, bonds, notes or other similar instruments issued by us that, by their terms, are senior or senior subordinated debt securities;

• all capital lease obligations;

• all obligations issued or assumed as the deferred purchase price of property, all conditional sale obligations and all obligations of the Company under any title retention agreement (but excluding trade accounts payable arising in the ordinary course of business and long- term purchase obligations);

• all obligations for the reimbursement of any letter of credit, banker’s acceptance, security purchase facility or similar credit transaction;

• all obligations of the type referred to in first four bullet points above of other persons the payment of which we are responsible or liable as obligor, guarantor or otherwise; and

• all obligations of the type referred to in the first four bullet points above of other persons secured by any lien on any property or asset of the Company (whether or not such obligation is assumed by the Company), except for (1) any such indebtedness that is by its terms subordinated to or that ranks equally with the subordinated notes and (2) any unsecured indebtedness between or among us or our affiliates. Such Senior Indebtedness shall continue to be Senior Indebtedness and be entitled to the benefits of the subordination provisions contained in the Subordinated Note Indenture irrespective of any amendment, modification or waiver of any term of such Senior Indebtedness.

16

The Subordinated Note Indenture does not limit the aggregate amount of Senior Indebtedness that we may issue. At December 31, 2019, the outstanding Senior Indebtedness of PG&E Corporation totaled approximately $650 million. In addition, at December 31, 2019, we had $1.5 billion outstanding under our debtor-in-possession credit facility.

Additional Interest

“Additional Interest” is defined in the Subordinated Note Indenture as (i) such additional amounts as may be required so that the net amounts received and retained by a holder of subordinated notes (if the holder is a Securities Trust (as defined in the Subordinated Note Indenture) formed to issue Trust Securities (as defined in the Subordinated Note Indenture), the proceeds of which are used to purchase subordinated notes of one or more series) after paying taxes, duties, assessments or governmental charges of whatever nature (other than withholding taxes) imposed by the United States or any other taxing authority will not be less than the amounts the holder would have received had no such taxes, duties, assessments or other governmental charges been imposed; and (ii) any interest due and not paid on an interest payment date, together with interest on such interest due from such interest payment date to the date of payment, compounded quarterly, on each interest payment date.

Certain Covenants

The Company covenants in the Subordinated Note Indenture, for the benefit of the holders of each series of subordinated notes, that:

• if the Company shall have given notice of its election to extend an interest payment period for such series of subordinated notes and such extension shall be continuing;

• if the Company shall be in default with respect to its payment or other obligations under the guarantee with respect to the Trust Securities, if any, related to such series of subordinated notes; or

• if an Event of Default under the Subordinated Note Indenture with respect to such series of subordinated notes shall have occurred and be continuing;

(a) the Company shall not declare or pay any dividend or make any distributions with respect to, or redeem, purchase, acquire or make a liquidation payment with respect to, any of its capital stock, and (b) the Company shall not make any payment of interest, principal or premium, if any, on or repay, repurchase or redeem any debt securities (including guarantees other than the guarantee with respect to the series of Trust Securities, if any, related to such series of subordinated notes) issued by the Company which rank equally with or junior to the subordinated notes.

None of the foregoing, however, shall restrict:

• any of the actions described in the preceding sentence resulting from any reclassification of the Company’s capital stock or the exchange or conversion of one class or series of the Company’s capital stock for another class or series of the Company’s capital stock; or

• the purchase of fractional interests in shares of the Company’s capital stock pursuant to the conversion or exchange provisions of such capital stock or the security being converted or exchanged.

Modification

The Subordinated Note Indenture contains provisions permitting us and the Subordinated Note Indenture Trustee, with the consent of the holders of not less than a majority in principal amount of the outstanding subordinated notes of each series that is affected, to modify the Subordinated Note Indenture or the rights of the

17

holders of the subordinated notes of such series; provided, that no such modification may, without the consent of the holder of each outstanding subordinated note that is affected:

• change the stated maturity of the principal of, or any installment of principal of or interest on, any subordinated note, or reduce the principal amount of any subordinated note or the rate of interest (including Additional Interest) of any subordinated note or any premium payable upon the redemption of any subordinated note, or change the method of calculating the rate of interest on any subordinated note, or impair the right to institute suit for the enforcement of any such payment on or after the stated maturity of any subordinated note (or, in the case of redemption, on or after the redemption date); or

• reduce the percentage of principal amount of the outstanding subordinated notes of any series, the consent of whose holders is required for any such supplemental indenture, or the consent of whose holders is required for any waiver (of compliance with certain provisions of the Subordinated Note Indenture or certain defaults under the Subordinated Note Indenture and their consequences) provided for in the Subordinated Note Indenture; or

• modify any of the provisions of the Subordinated Note Indenture relating to supplemental indentures, waiver of past defaults, or waiver of certain covenants, except to increase any such percentage or to provide that certain other provisions of the Subordinated Note Indenture cannot be modified or waived without the consent of the holder of each outstanding subordinated note that is affected; or

• modify the provisions of the Subordinated Note Indenture with respect to the subordination of the subordinated notes in a manner adverse to such holder.

In addition, we and the Subordinated Note Indenture Trustee may execute, without the consent of any holders of subordinated notes, any supplemental indenture for certain other usual purposes, including the creation of any new series of subordinated notes.

Events of Default

The Subordinated Note Indenture provides that any one or more of the following described events with respect to the subordinated notes of any series, which has occurred and is continuing, constitutes an “Event of Default” with respect to the subordinated notes of such series:

• failure for 30 days to pay interest on the subordinated notes of such series, including any Additional Interest (as defined in clause (ii) of the definition of Additional Interest in the Subordinated Note Indenture) on such unpaid interest, when due on an interest payment date other than at maturity or upon earlier redemption; provided, however, that a valid extension of the interest payment period by the Company shall not constitute a default in the payment of interest for this purpose; or

• failure for 30 days to pay Additional Interest (as defined in clause (i) of the definition of Additional Interest in the Subordinated Note Indenture); or

• failure to pay principal or premium, if any, or interest, including Additional Interest (as defined in clause (ii) of the definition of Additional Interest in the Subordinated Note Indenture), on the subordinated notes of such series when due at maturity or upon earlier redemption; or

• failure for three Business Days to deposit any sinking fund payment when due by the terms of a subordinated note of such series; or

• failure to observe or perform any other covenant or warranty of the Company in the Subordinated Note Indenture (other than a covenant or warranty which has expressly been included in the Subordinated Note Indenture solely for the benefit of one or more series of subordinated notes other than such series) for 90 days after written notice to the Company from the Subordinated Note Indenture Trustee or to the Company and the Subordinated Note Trustee from the holders of at least 33% in principal amount of the outstanding subordinated notes of such series; or

• certain events of bankruptcy, insolvency or reorganization of the Company.

18

The holders of not less than a majority in aggregate outstanding principal amount of the subordinated notes of any series have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Subordinated Note Indenture Trustee with respect to the subordinated notes of such series. If a Subordinated Note Indenture Event of Default occurs and is continuing with respect to the subordinated notes of any series, then the Subordinated Note Indenture Trustee or the holders of not less than 33% in aggregate outstanding principal amount of the subordinated notes of such series may declare the principal amount of the subordinated notes due and payable immediately by notice in writing to the Company (and to the Subordinated Note Indenture Trustee if given by the holders), and upon any such declaration such principal amount shall become immediately due and payable. At any time after such a declaration of acceleration with respect to the subordinated notes of any series has been made and before a judgment or decree for payment of the money due has been obtained as provided in Article Five of the Subordinated Note Indenture, the holders of not less than a majority in aggregate outstanding principal amount of the subordinated notes of such series may rescind and annul such declaration and its consequences if the default has been cured or waived and the Company has paid or deposited with the Subordinated Note Indenture Trustee a sum sufficient to pay all matured installments of interest (including any Additional Interest) and principal due otherwise than by acceleration and all sums paid or advanced by the Subordinated Note Indenture Trustee, including reasonable compensation and expenses of the Subordinated Note Indenture Trustee.

The holders of not less than a majority in aggregate outstanding principal amount of the subordinated notes of any series may, on behalf of the holders of all the subordinated notes of such series, waive any past default with respect to such series, except (i) a default in the payment of principal or interest or (ii) a default in respect of a covenant or provision which under Article Nine of the Subordinated Note Indenture cannot be modified or amended without the consent of the holder of each outstanding subordinated note of such series affected.

Satisfaction and Discharge

Any subordinated note, or any portion of the principal amount thereof, will be deemed to have been paid for purposes of the indenture, and our entire indebtedness in respect of the subordinated notes will be deemed to have been satisfied and discharged if certain conditions are satisfied, including an irrevocable deposit with the Subordinated Note Indenture Trustee or any paying agent (other than us) in trust of:

• money in an amount which will be sufficient; or

• in the case of a deposit made prior to the maturity of the subordinated notes or portions thereof, Eligible Obligations (as defined below) which do not contain provisions permitting the redemption or other prepayment thereof at the option of the issuer thereof, the principal of and the interest on which when due, without any regard to reinvestment thereof, will provide monies which, together with the money, if any, deposited with or held by the Subordinated Note Indenture Trustee or the paying agent, will be sufficient; or

• a combination of either of the two items described in the two preceding bullet points which will be sufficient;

to pay when due the principal of and premium, if any, and interest, if any, due and to become due on the subordinated notes or portions thereof.

This discharge of the subordinated notes through the deposit with the Subordinated Note Indenture Trustee of cash or Eligible Obligations generally will be treated as a taxable disposition for U.S. federal income tax purposes by the holders of those subordinated notes. Prospective investors in the subordinated notes should consult their own tax advisors as to the particular U.S. federal income tax consequences applicable to them in the event of such discharge.

For purposes of this subsection, “Eligible Obligations” for U.S. dollar-denominated subordinated notes, means securities that are direct obligations of, or obligations unconditionally guaranteed by, the United States,

19

entitled to the benefit of the full faith and credit thereof, or depositary receipts issued by a bank as custodian with respect to these obligations or any specific interest or principal payments due in respect thereof held by the custodian for the account of the holder of a depository receipt.

Information Concerning the Subordinated Note Indenture Trustee

The Subordinated Note Indenture Trustee, prior to an Event of Default with respect to subordinated notes of any series, undertakes to perform, with respect to subordinated notes of such series, only such duties as are specifically set forth in the Subordinated Note Indenture and, in case an Event of Default with respect to subordinated notes of any series has occurred and is continuing, shall exercise, with respect to subordinated notes of such series, the same degree of care as a prudent individual would exercise in the conduct of his or her own affairs. Subject to such provision, the Subordinated Note Indenture Trustee is under no obligation to exercise any of the powers vested in it by the Subordinated Note Indenture at the request of any holder of subordinated notes of any series, unless offered reasonable indemnity by such holder against the costs, expenses and liabilities which might be incurred by the Subordinated Note Indenture Trustee. The Subordinated Note Indenture Trustee is not required to expend or risk its own funds or otherwise incur any financial liability in the performance of its duties if the Subordinated Note Indenture Trustee reasonably believes that repayment or adequate indemnity is not reasonably assured to it.

The Company and certain of its subsidiaries may maintain deposit accounts and banking relationships with the Subordinated Note Indenture Trustee. The Subordinated Note Indenture Trustee and certain of its affiliates may also serve as trustee under other indentures pursuant to which securities of the Company and certain subsidiaries of the Company are outstanding.

Governing Law

The Subordinated Note Indenture and the subordinated notes will be governed by, and construed in accordance with, the internal laws of the State of New York.

Miscellaneous

We will have the right at all times to assign any of our rights or obligations under the Subordinated Note Indenture to a direct or indirect wholly-owned subsidiary of ours; provided, that, in the event of any such assignment, we will remain primarily liable for all such obligations. Subject to the foregoing, the Subordinated Note Indenture will be binding upon and inure to the benefit of the parties to the Subordinated Note Indenture and their respective successors and assigns.

DESCRIPTION OF THE DEBT SECURITIES OF PACIFIC GAS AND ELECTRIC COMPANY

UNSECURED SENIOR NOTES

This prospectus describes certain general terms of the unsecured senior notes (“senior notes”) that we may sell from time to time under this prospectus. We will describe the specific terms of each series of senior notes we offer in a prospectus supplement. The senior notes will be issued under an indenture dated as of August 6, 2018 between us and BOKF, N.A., as successor trustee (the “Senior Note Indenture Trustee”). The indenture, as amended or supplemented from time to time, is referred to as the “Indenture.” We have summarized selected provisions of the Indenture and the senior notes below. The information we are providing you in this prospectus concerning the senior notes and the Indenture is only a summary of the information provided in those documents, and the summary is qualified in its entirety by reference to the provisions of the Indenture, including the forms of senior notes attached thereto. You should consult the senior notes themselves and the Indenture for more complete information on the senior notes as they, and not this prospectus or any applicable prospectus supplement, govern your rights as a holder. The Indenture is included as an exhibit to the registration statement of which this prospectus is a part. The Indenture has been qualified under the Trust Indenture Act of 1939, as amended, or the Trust Indenture Act, and the terms of the senior notes will include those made part of the Indenture by the Trust Indenture Act.

In this section, references to “we,” “our,” “ours” and “us” refer only to Pacific Gas and Electric Company and not to any of its direct or indirect subsidiaries or affiliates except as expressly provided.

General

The senior notes are our unsecured general obligations and will rank equally in right of payment to all our other existing and future unsecured and unsubordinated obligations. The senior notes will be effectively subordinated to all our secured debt, including our first mortgage bonds to be issued from time to time under our mortgage indenture. Upon execution by us and the related mortgage trustee, the mortgage indenture will constitute a first lien, subject to permitted liens, on substantially all of our real property and certain tangible personal property related to our facilities. The senior notes will be entitled to the benefit of the Indenture equally and ratably with all other senior notes issued under the Indenture.

The Indenture does not limit the amount of debt we may issue under it or the amount of debt we or our subsidiaries may otherwise incur. We may issue senior notes from time to time under the Indenture in one or more series by entering into supplemental indentures or by resolution of our board of directors.

Provisions of a Particular Series

The prospectus supplement applicable to each series of senior notes will specify, among other things:

• the title of the senior notes;

• any limit on the aggregate principal amount of the senior notes;

• the date or dates on which the principal of the senior notes is payable, including the maturity date, or the method or means by which those dates will be determined, and our right, if any, to extend those dates and the duration of any extension;

• the interest rate or rates of the senior notes, if any, which may be fixed or variable, or the method or means by which the interest rate or rates will be determined, and our ability to extend any interest payment periods and the duration of any extension;

• the date or dates from which any interest will accrue, the dates on which we will pay interest on the senior notes and the regular record date, if any, for determining who is entitled to the interest payable on any interest payment date;

21

• the place or places where the principal of (and premium, if any) and interest, if any, on such senior notes shall be payable;

• the methods by which registration of transfer of senior notes and exchanges of senior notes may be effected, and by which notices and demands to or upon us in respect of such senior notes may be made, given, furnished, filed or served;

• any periods or periods within which, or date or dates on which, the price or prices at which and the terms and conditions on which the senior notes may be redeemed, in whole or in part, at our option, and any restrictions on such redemptions;

• any obligation of ours to redeem, purchase or repay the senior notes pursuant to any sinking fund or other mandatory redemption provisions or at the option of the holder and the terms and conditions upon which the senior notes will be so redeemed, purchased or repaid;

• the denominations in which we will authorize the senior notes to be issued, if other than $1,000 or integral multiples of $1,000;

• whether we will offer the senior notes in the form of global securities and, if so, the name of the depositary for any global securities;

• if the amount payable in respect of principal of or any premium or interest on any senior notes may be determined with reference to an index or other fact or event ascertainable outside the Indenture, the manner in which such amount will be determined;

• covenants for the benefit of the holders of that series;

• the currency or currencies in which the principal, premium, if any, and interest on the senior notes will be payable if other than U.S. dollars and the method for determining the equivalent amount in U.S. dollars;

• if the principal of the senior notes is payable from time to time without presentation or surrender, any method or manner of calculating the principal amount that is outstanding at any time for purposes of the Indenture; and

We may sell senior notes at par or at a discount below their stated principal amount. We will describe in a prospectus supplement material U.S. federal income tax considerations, if any, and any other special considerations for any senior notes we sell that are denominated in a currency other than U.S. dollars.

Payment

Except as may be provided with respect to a series, interest, if any, on the senior notes payable on each interest payment date will be paid to the person in whose name that senior note is registered as of the close of business on the regular record date for the interest payment date. However, interest payable at maturity will be paid to the person to whom the principal is paid. If there has been a default in the payment of interest on any senior notes, the defaulted interest may be paid to the holders of the senior notes as of a special record date for the payment of such defaulted interest which shall not be more than 30 days and not less than 10 days prior to the date of the proposed payment and not less than 25 days after the receipt by the Senior Note Indenture Trustee of the notice of the proposed payment.

Redemption

Any terms for the optional or mandatory redemption of a series of senior notes will be set forth in a prospectus supplement for the offered series. Unless otherwise indicated in a prospectus supplement, senior notes

22

will be redeemable by us only upon notice sent to the holders of senior notes not less than 10 nor more than 60 days before the date fixed for redemption and, if less than all the senior notes of a series are to be redeemed, the particular senior notes to be redeemed will be selected by the method provided for that particular series, or in the absence of any such provision, by such method of random selection as the registrar deems fair and appropriate; provided, however, that with respect to global securities (as defined herein), senior notes to be redeemed shall be selected in accordance with the procedures of the depositary.

We have reserved the right to provide conditional redemption notices for redemptions at our option or for redemptions that are contingent upon the occurrence or nonoccurrence of an event or condition that cannot be ascertained prior to the time we are required to notify holders of the redemption. A conditional notice may state that if we have not deposited redemption funds with the Senior Note Indenture Trustee or a paying agent on or before the redemption date or we have directed the Senior Note Indenture Trustee or paying agent not to apply money deposited with it for redemption of senior notes, we will not be required to redeem the senior notes on the redemption date.

Restrictions on Liens and Sale and Leaseback Transactions

The Indenture does not permit us or any of our Significant Subsidiaries (as defined below) to, (i) issue, incur, assume or permit to exist any Debt (as defined below) secured by a Lien (as defined below) on any of our Principal Property (as defined below), whether that Principal Property was owned when the Indenture was executed (August 6, 2018) or thereafter acquired, unless we provide that the outstanding senior notes will be equally and ratably secured by such Liens for as long as any such Debt shall be so secured or (ii) incur or permit to exist any Attributable Debt (as defined below) in respect of Principal Property; provided, however, that the foregoing restriction will not apply to the following:

• any Lien existing on August 6, 2018;

• to the extent we or any Significant Subsidiary consolidates with, or merges with or into, another entity, Liens on the property of such entity securing Debt in existence on the date of such consolidation or merger, provided that such Debt and Liens were not created or incurred in anticipation of such consolidation or merger and that such Liens do not extend to or cover any such Principal Property;

Consolidation, Merger, Conveyance or Other Transfer

We may not consolidate with or merge with or into any other Person (as defined below) or convey, or otherwise transfer, or lease, all or substantially all of our Principal Property to any Person unless:

• the Person formed by that consolidation or into which we are merged or the Person which acquires by conveyance or other transfer, or which leases, all or substantially all of the principal properties and assets is a corporation, partnership, limited liability company, association, company, joint stock company or business trust, organized and existing under the laws of the United States, or any state thereof or the District of Columbia;

• the Person executes and delivers to the Senior Note Indenture Trustee a supplemental indenture that in the case of a consolidation, merger, conveyance or other transfer, or in the case of a lease if the term thereof extends beyond the last stated maturity of the senior notes then outstanding, contains an assumption by the successor corporation of the due and punctual payment of the principal of and premium, if any, and interest, if any, on all senior notes then outstanding and the performance and observance of every covenant and condition under the Indenture to be performed or observed by us;

• in the case of a lease, the lease is made expressly subject to termination by us at any time during the continuance of an Event of Default under the Indenture;

In the case of a conveyance or other transfer of all or substantially all of our principal properties and assets to any Person as contemplated under the Indenture, upon the satisfaction of all the conditions described above, we (as we would exist without giving effect to the transaction) would be released and discharged from all obligations and covenants under the Indenture and under the senior notes then outstanding unless we elect to waive the release and discharge.

The meaning of the term “substantially all” has not been definitively established and is likely to be interpreted by reference to applicable state law if and at the time the issue arises and will depend on the facts and circumstances existing at the time.

For purposes of this subsection, “Person” means any individual, corporation, limited liability partnership, joint venture, trust or unincorporated organization, or any other entity, whether or not a legal entity, or any Governmental Authority (as such term is defined in the Indenture).

Additional Covenants

We have agreed in the Indenture, among other things:

• to maintain a place of payment for any series of senior notes;

• to maintain our corporate existence (subject to the provisions above relating to mergers and consolidations); and

• to deliver to the Senior Note Indenture Trustee an annual officer’s certificate with respect to our compliance with our obligations under the Indenture.

Modification of the Indenture; Waiver

We and the Senior Note Indenture Trustee may, with the consent of the holders of not less than a majority in aggregate principal amount of the senior notes of each affected series then outstanding under the Indenture, considered as one class, modify or amend the Indenture, including the provisions relating to the rights of the holders of senior notes of the affected series. However, no modification or amendment may, without the consent of each holder of affected senior notes:

• change the stated maturity (except as provided by the terms of a series of senior notes) of the principal of, or interest on, the senior note or reduce the principal amount or any premium payable on the senior note or reduce the interest rate of the senior note, or change the method of calculating the interest rate with respect to the senior note;

• reduce the amount of principal of any discount senior note that would be payable upon acceleration of the maturity of the senior note;

• change the coin, currency or other property in which the senior note or interest or premium on the senior note is payable;

• impair the right to institute suit for the enforcement of any payment on the senior note;

• reduce the percentage in principal amount of outstanding senior notes of any series the consent of whose holders is required for modification or amendment of the Indenture or for waiver of compliance with certain provisions of the Indenture or for waiver of defaults;

27

• reduce the quorum or voting requirements applicable to holders of the senior notes; or

• modify the provisions of the Indenture with respect to modification and waiver, except as provided in the Indenture.

We and the Senior Note Indenture Trustee may, without the consent of any holder of senior notes, modify and amend the Indenture for certain purposes, including, but not limited to, the following:

• to evidence the succession of another Person to the Company and the assumption by any such successor of our covenants in the Indenture and in the senior notes;

• add covenants or other provisions applicable to us and for the benefit of the holders of senior notes or one or more specified series thereof or to surrender any right or power conferred on us;

• establish the form or terms of senior notes of any series as contemplated by the Indenture;

• cure any ambiguity or to correct or supplement any provision of the Indenture which may be defective or inconsistent with other provisions;

• make any other additions to, deletions from or changes to the provisions under the Indenture so long as the additions, deletions or changes do not materially adversely affect the holders of any series of senior notes in any material respect;

• change or eliminate any provision of the Indenture or add any new provision so long as the change, elimination or addition does not adversely affect the interests of holders of senior notes of any series in any material respect;

• change any place or places for payment or surrender of senior notes and where notices and demands to us may be served;

• comply with any requirement in connection with the qualification of the Indenture under the Trust Indenture Act; and

• comply with the rules of any applicable securities depository.

The holders of not less than a majority in aggregate principal amount of the senior notes of each affected series then outstanding under the Indenture, voting as a single class, may waive compliance by us with our covenant in respect of our corporate existence and the covenants described under “Restrictions on Liens and Sale and Leaseback Transactions” and “Consolidation, Merger, Conveyance or Other Transfer” and with certain other covenants and restrictions that may apply to a series of senior notes as provided in the Indenture. The holders of not less than a majority in aggregate principal amount of the senior notes outstanding may, on behalf of the holders of all of the senior notes, waive any past default under the Indenture and its consequences, except a default in the payment of the principal of or any premium or interest on any senior note and defaults in respect of a covenant or provision in the Indenture which cannot be modified, amended or waived without the consent of each holder of affected senior notes.

In order to determine whether the holders of the requisite principal amount of the outstanding senior notes have taken an action under the Indenture as of a specified date:

• the principal amount of a senior note that will be deemed to be outstanding will be the amount of the principal that would be due and payable as of that date upon acceleration of the maturity to that date; and

• senior notes owned by us or any other obligor upon the senior notes or any of our or their affiliates will be disregarded and deemed not to be outstanding.

Events of Default

An “Event of Default” means any of the following events which shall occur and be continuing:

• failure to pay interest on a senior note within 30 days after the interest becomes due and payable;

28

• failure to pay the principal of, or sinking fund installments or premium, if any, on, a senior note when due and payable;

• failure to perform or breach of any other covenant or warranty applicable to us in the Indenture continuing for 90 days after the Senior Note Indenture Trustee gives us, or the holders of at least 33% in aggregate principal amount of the senior notes then outstanding give us and the Senior Note Indenture Trustee, written notice specifying the default or breach and requiring us to remedy the default or breach, unless the Senior Note Indenture Trustee is directed by the holders of a principal amount of senior notes not less than the principal amount of senior notes the holders of which gave that notice to agree in writing to an extension of the period prior to its expiration;

• certain events of bankruptcy, insolvency or reorganization; and

• the occurrence of any Event of Default as defined in any mortgage, indenture or instrument under which there may be issued, or by which there may be secured or evidenced, any of our Debt, whether the Debt existed on August 6, 2018 or is thereafter created, if the Event of Default: (i) is caused by a failure to pay principal after final maturity of the debt after the expiration of the grace period provided in the Debt (which we refer to as a “payment default”) or (ii) results in the acceleration of the Debt prior to its express maturity, and, in each case, the principal amount of the Debt, together with the principal amount of any other Debt under which there has been a payment default or the maturity of which has been so accelerated, aggregates $150 million or more.

The $150 million amount specified in the bullet point above shall be increased in any calendar year subsequent to 2018 by the same percentage increase in the urban CPI Index (as defined in the Indenture) for the period commencing January 1, 2018 and ending on January 1 of the applicable calendar year. “Debt” for the purpose of the bullet point above means any debt of ours for money borrowed but, in each case, excluding liabilities in respect of capital lease obligations or swap agreements.

For purposes of this subsection, the following terms have the following meaning:

• “Debt” means any debt of the Company for money borrowed and guarantees by the Company of debt for money borrowed but in each case excluding liabilities in respect of Capital Lease Obligations or Swap Agreements.

• “Capital Lease Obligation” means, at the time any determination is to be made, the amount of the liability in respect of a capital lease that would at that time be required to be capitalized on a balance sheet in accordance with GAAP.

• “Swap Agreement” means any agreement with respect to any swap, forward, future or derivative transaction or option or similar agreement involving, or settled by reference to, one or more rates, currencies, commodities, equity or debt instruments or securities, or economic, financial or pricing indices or measures of economic, financial or pricing risk or value or any similar transaction or any combination of these transactions.

If the Senior Note Indenture Trustee deems it to be in the interest of the holders of the senior notes, it may withhold notice of default, except defaults in the payment of principal of or interest or premium on or with respect to, any senior note.

If an Event of Default occurs and is continuing, the Senior Note Indenture Trustee or the holders of not less than 33% in aggregate principal amount of the senior notes outstanding, considered as one class, may declare all principal due and payable immediately by notice in writing to us (and to the Senior Note Indenture Trustee if given by holders); provided, however, that if an Event of Default occurs with respect to the specified events of bankruptcy, insolvency or reorganization, then the senior notes outstanding shall be due and payable immediately without further action by the Senior Note Indenture Trustee or holders. If, after such a declaration of acceleration, we pay or deposit with the Senior Note Indenture Trustee all overdue interest and principal and premium on

29

senior notes that would have been due otherwise, plus any interest and other conditions specified in the Indenture have been satisfied before a judgment or decree for payment has been obtained by the Senior Note Indenture Trustee as provided in the Indenture, the event or events of default giving rise to the acceleration will be deemed to have been waived and the declaration of acceleration and its consequences will be deemed to have been rescinded and annulled.

No holder of senior notes will have any right to enforce any remedy under the Indenture unless the holder has given the Senior Note Indenture Trustee written notice of a continuing Event of Default, the holders of at least 33% in aggregate principal amount of the senior notes outstanding have requested the Senior Note Indenture Trustee in writing to institute proceedings in respect of the Event of Default in its own name as Senior Note Indenture Trustee under the Indenture and the holder or holders have offered the Senior Note Indenture Trustee reasonable indemnity against costs, expenses and liabilities with respect to the request, the Senior Note Indenture Trustee has failed to institute any proceeding within 60 days after receiving the notice from holders, and no direction inconsistent with the written request has been given to the Senior Note Indenture Trustee during the60-day period by holders of at least a majority in aggregate principal amount of senior notes then outstanding.

The Senior Note Indenture Trustee is not required to risk its funds or to incur financial liability if there is a reasonable ground for believing that repayment to it or adequate indemnity against risk or liability is not reasonably assured.

If an Event of Default has occurred and is continuing, holders of not less than a majority in principal amount of the senior notes then outstanding generally may direct the time, method and place of conducting any proceedings for any remedy available to the Senior Note Indenture Trustee, or exercising any trust or power conferred upon the Senior Note Indenture Trustee; provided the direction could not conflict with any rule of law or with the Indenture, and could not involve the Senior Note Indenture Trustee in personal liability where indemnity would not, in the Senior Note Indenture Trustee’s sole discretion, be adequate.

Satisfaction and Discharge

Any senior note, or any portion of the principal amount thereof, will be deemed to have been paid for purposes of the Indenture, and our entire indebtedness in respect of the senior notes will be deemed to have been satisfied and discharged, if certain conditions are satisfied, including an irrevocable deposit with the Senior Note Indenture Trustee or any paying agent (other than us) in trust of:

• money in an amount which will be sufficient; or

• in the case of a deposit made prior to the maturity of the senior notes or portions thereof, eligible obligations (as described below) which do not contain provisions permitting the redemption or other prepayment thereof at the option of the issuer thereof, the principal of and the interest on which when due, without any regard to reinvestment thereof, will provide monies which, together with the money, if any, deposited with or held by the Senior Note Indenture Trustee or the paying agent, will be sufficient; or

• a combination of either of the two items described in the two preceding bullet points which will be sufficient;

to pay when due the principal of and premium, if any, and interest, if any, due and to become due on the senior notes or portions thereof.

This discharge of the senior notes through the deposit with the Senior Note Indenture Trustee of cash or eligible obligations generally will be treated as a taxable disposition for U.S. federal income tax purposes by the holders of those senior notes. Prospective investors in the senior notes should consult their own tax advisors as to the particular U.S. federal income tax consequences applicable to them in the event of such discharge.

30

For this purpose, “eligible obligations” for U.S. dollar-denominated senior notes, means securities that are direct obligations of, or obligations unconditionally guaranteed by, the United States, entitled to the benefit of the full faith and credit thereof, or depositary receipts issued by a bank as custodian with respect to these obligations or any specific interest or principal payments due in respect thereof held by the custodian for the account of the holder of a depository receipt.

Transfer and Exchange

Subject to the terms of the Indenture, senior notes of any series may be exchanged for other senior notes of the same series of authorized denominations and of like aggregate principal amount and tenor. Subject to the terms of the Indenture and the limitations applicable to global securities, senior notes may be presented for exchange or registration of transfer at the office of the registrar without service charge, upon payment of any taxes and other governmental charges imposed on registration of transfer or exchange. Such transfer or exchange will be effected upon the Senior Note Indenture Trustee, us or the registrar, as the case may be, being satisfied with the instruments of transfer.

If we provide for any redemption of a series of senior notes, we will not be required to execute, register the transfer of or exchange any senior note of that series for 15 days before a notice of redemption is given or register the transfer of or exchange any senior note selected for redemption.

Resignation or Removal of Trustee

The Senior Note Indenture Trustee may resign at any time upon written notice to us and the Senior Note Indenture Trustee may be removed at any time by written notice delivered to the Senior Note Indenture Trustee and us and signed by the holders of at least a majority in principal amount of the outstanding senior notes. No resignation or removal of a trustee will take effect until a successor trustee accepts appointment. In addition, under certain circumstances, we may remove the Senior Note Indenture Trustee. We must give notice of resignation and removal of the Senior Note Indenture Trustee or the appointment of a successor trustee to all holders of senior notes as provided in the indenture.

Trustees, Paying Agents and Registrars for the Senior Notes

BOKF, N.A. will act as the Senior Note Indenture Trustee, paying agent and registrar under the indenture. We may change either the paying agent or registrar without prior notice to the holders of the senior notes, and we may act as paying agent.

Governing Law

The Indenture and the senior notes are governed by New York law.

• the title of the first mortgage bonds and, if other than the date of its authentication, the date of each first mortgage bond of such series;

• any limitation on the aggregate principal amount of the first mortgage bonds;

Payment

Except as may be provided with respect to a series, interest, if any, on the first mortgage bonds payable on each interest payment date will be paid to the person in whose name that first mortgage bond is registered as of the close of business on the regular record date for the interest payment date. However, interest payable at maturity will be paid to the person to whom the principal is paid. If there has been a default in the payment of interest on any first mortgage bonds, the defaulted interest may be paid to the holders of the first mortgage bonds as of a special record date for the payment of such defaulted interest which shall not be more than 30 days and not less than 10 days prior to the date of the proposed payment and not less than 25 days after the receipt by the Mortgage Trustee of the notice of the proposed payment.

Redemption

Any terms for the optional or mandatory redemption of a series of first mortgage bonds will be set forth in a prospectus supplement for the offered series. Unless otherwise indicated in a prospectus supplement, first mortgage bonds will be redeemable by us only upon notice sent not less than 10 nor more than 60 days before the date fixed for redemption and, if less than all the first mortgage bonds of a series are to be redeemed, the

33

particular first mortgage bonds to be redeemed will be selected by the method provided for that particular series, or in the absence of any such provision, by such method of random selection as the registrar deems fair and appropriate; provided, however, that with respect to global securities (as described below), first mortgage bonds to be redeemed shall be selected in accordance with the procedures of the depositary.

We have reserved the right to provide conditional redemption notices for redemptions at our option or for redemptions that are contingent upon the occurrence or nonoccurrence of an event or condition that cannot be ascertained prior to the time we are required to notify holders of the redemption. A conditional notice may state that if we have not deposited redemption funds with the Mortgage Trustee or a paying agent on or before the redemption date or we have directed the Mortgage Trustee or paying agent not to apply money deposited with it for redemption of first mortgage bonds, we will not be required to redeem the first mortgage bonds on the redemption date.

Lien of the Mortgage Indenture

General

From and after the Lien Effective Date, the Mortgage Indenture will create a first lien, subject to Permitted Liens, on substantially all of our real property and certain tangible personal property related to our facilities. We refer to property that is subject to the lien of the Mortgage Indenture as “Mortgaged Property” and property that is excepted from the lien of the Mortgage Indenture as “Excepted Property.”

The Mortgage Indenture provides that after-acquired property (other than after-acquired property qualifying as Excepted Property) located in the State of California will be subject to the lien of the Mortgage Indenture (subject to Permitted Liens); provided, however, that in the case of a consolidation or merger (whether or not we are the surviving corporation) or the transfer or lease of all or substantially all of the Mortgaged Property, the Mortgage Indenture will not be required to be a lien upon any of the properties then owned or thereafter acquired by the successor corporation except properties acquired from us in or as a result of that transaction, to the extent not constituting Excepted Property, and improvements, extensions and additions to those properties and renewals, replacements and substitutions of or for any part or parts thereof. In addition, after-acquired property may be subject to liens existing or placed thereon at the time of acquisition thereof, including, but not limited to, purchase money liens, and, in certain circumstances, liens attaching to the property prior to the recording or filing of an instrument specifically subjecting the property to the lien of the Mortgage Indenture.

The Mortgage Indenture provides that, from and after the Lien Effective Date, the Mortgage Trustee shall have a lien, prior to the first mortgage bonds, on the Mortgaged Property and on all other property and funds held or collected by the Mortgage Trustee, other than property and funds held in trust for the payment of principal, premium, if any, and interest on the first mortgage bonds, as security for the payment of the Mortgage Trustee’s reasonable compensation and expenses, and as security for the performance by us of our obligation to indemnify the Mortgage Trustee against certain liabilities.

Without the consent of the holders, we and the Mortgage Trustee may enter into supplemental indentures in order to subject additional property to the lien of the Mortgage Indenture (including property which would otherwise be Excepted Property). This property would thereupon constitute Property Additions (so long as it would otherwise qualify as Property Additions as described below) and be available as a basis for the issuance of additional first mortgage bonds. See “— Issuance of Additional First Mortgage Bonds.”

“Lien Effective Date” means the date of delivery by the Company to the Trustee of each of the following:

• an officer’s certificate stating that, prior to or concurrently with the Lien Effective Date:

• the Effective Date (as defined in the Plan) has occurred; and

• any further security documents required to create the lien in the Mortgaged Property will be executed and delivered (to the extent any such document is required to be delivered on such date):

34

• a company order requesting execution and delivery by the Mortgage Trustee of a supplemental indenture (such company order to be accompanied by the documents required by Section 1.04 of the Mortgage Indenture), if deemed necessary or desirable by the Company to effectuate the lien of the Mortgage Indenture, and such other instruments (in form and substance reasonably satisfactory to the Mortgage Trustee) as the Company may deem necessary or desirable to effectuate the lien of the Mortgage Indenture; and

• an officer’s certificate stating that, to the knowledge of the signer, no event of default has occurred and is continuing.

For purposes of this definition, the following terms have the following meaning:

“Bankruptcy Court” means the United States Bankruptcy Court for the Northern District Of California.

“Confirmation Order” means the confirmation order entered by the Bankruptcy Court confirming the Plan and approving the transactions contemplated thereby.

“DIP Credit Agreement” means that certain Senior Secured Superpriority Debtor in Possession Credit, Guaranty and Security Agreement, dated as of February 1, 2019, among the Company, as borrower, PG&E Corporation, as guarantor, JPMorgan Chase Bank, N.A., as administrative agent, and Citibank, N.A., as collateral agent.

“Plan” means the Debtors��� and Shareholder Proponents Joint Plan of Chapter 11 Reorganization Dated March 16, 2020 [Docket No. 6320] filed by the Company and PG&E Corporation with the Bankruptcy Court (as may be modified, amended, or supplemented from time to time and, together with all exhibits and schedules thereto).

Excepted Property

From and after the Lien Effective Date, the Mortgage Indenture will constitute a first lien, subject to Permitted Liens, on substantially all of our real property and certain tangible personal property related to our facilities, located in the State of California, except for the Diablo Canyon nuclear power plant, our corporate offices, certain specified properties as set forth in the Mortgage Indenture and the following Excepted Property (unless otherwise indicated in any applicable prospectus supplement):

If an Event of Default occurs under the Mortgage Indenture, certain of the Excepted Property may become subject to the lien of the Mortgage Indenture.

The Mortgage Indenture permits us to create or allow to exist certain “Permitted Liens,” such as mortgages, deeds of trust, pledges, security interests, leases, reservations, restrictions, charges, encumbrances, or other liens on the Mortgaged Property which rank senior to the lien of the Mortgage Indenture.

“Permitted Liens” include:

Issuance of Additional First Mortgage Bonds

We may issue first mortgage bonds of any series from time to time against Property Additions, Retired Securities (as described below) and cash deposited with the Mortgage Trustee, in an aggregate principal amount not exceeding:

• 70% of the aggregate of the net amounts of Property Additions which constitute Unfunded Property (as described below);

• the aggregate principal amount of previously issued first mortgage bonds that have been canceled or that we have delivered to the Mortgage Trustee for cancellation or previously issued first mortgage bonds deemed to have been paid under the Mortgage Indenture, each of which we refer to as “Retired Securities”; or

39

• the amount of cash deposited with the Mortgage Trustee.

“Property Additions” generally include any item, unit or element of property which is owned by us and is subject to the lien of the Mortgage Indenture except (with certain exceptions) goodwill, going concern value rights or intangible property, or any property the cost of acquisition or construction of which is properly chargeable to one of our operating expense accounts at the time of such acquisition or construction.

The Mortgage Indenture includes limitations on the issuance of first mortgage bonds against property subject to liens and upon the increase of the amount of any senior liens on Funded Property.

“Funded Property” generally means Mortgaged Property which has been used as the basis for the issuance of first mortgage bonds or as the basis for the release or substitution of Mortgaged Property under the Mortgage Indenture.

“Retired Securities” means, generally, first mortgage bonds which are no longer outstanding under the Mortgage Indenture, which have not been retired by the application of funded cash and which have not been used as the basis for the authentication and delivery of first mortgage bonds, the release of property or the withdrawal of cash.

“Unfunded Property” generally means Mortgaged Property which has not previously been used as the basis for the issuance of first mortgage bonds (not otherwise retired) or as the basis for the release or substitution of Mortgaged Property.

Release of Mortgaged Property

We may release property from the lien of the Mortgage Indenture if we deliver to the Mortgage Trustee cash equal to the Funded Property Basis (as described below) of the property to be released, less any taxes and expenses incidental to any sale, exchange, dedication or other disposition of the property to be released. Any of the following or any combination of the following will be applied as a credit against the cash we will be required to deliver to the Mortgage Trustee:

• the aggregate principal amount of obligations secured by a Purchase Money Lien on the property to be released, subject to certain limitations described below;

• an amount equal to the Net Cost or Net Fair Value to us (whichever is less) of certified Property Additions constituting Unfunded Property after certain deductions and additions, primarily including adjustments to offset property retirements (except that the adjustments need not be made if the Property Additions were acquired, made or constructed within 90 days before our request for release);

• an amount equal to ten-sevenths of the aggregate principal amount of first mortgage bonds we would be entitled to issue on the basis of retired first mortgage bonds (with that entitlement being waived by operation of such release); and

• an amount equal to ten-sevenths of the aggregate principal amount of first mortgage bonds delivered to the Mortgage Trustee.

For purposes of this subsection, the following terms have the following meaning:

• “Funded Property Basis” generally means the Net Cost of Funded Property or the Net Fair Value to us of the Funded Property at the time it became Funded Property, whichever is less.

• “Net Cost” means, as of the date of calculation, the cost of the property, less, if such property is subject to a senior lien, the lesser of (i) the outstanding principal amount of any senior lien obligations as of the date of calculation or (ii) the cost of the property.

40

• “Net Fair Value” means, as of the date of calculation, the fair value of the property, less, if such property is subject to a senior lien, the lesser of (i) the outstanding principal amount of any senior lien obligations as of the date of calculation or (ii) the fair value of the property.

• “Purchase Money Lien” means, generally, a lien on the property being released which is retained by the transferor of such property to secure all or part of its purchase price or granted to one or more other persons in connection with the transfer or release thereof, or granted to or held by a Mortgage Trustee or agent for any such persons, and may include liens which cover property in addition to the property being released and/or which secure additional indebtedness.

We will be permitted to release from the lien of the Mortgage Indenture Unfunded Property without depositing any cash with the Mortgage Trustee or providing any other credits if either (i) the lower of the Net Cost or Net Fair Value to us of all Unfunded Property (excluding the property to be released), after making certain adjustments, is at least zero, or (ii) the lower of the Net Cost or Net Fair Value to us of the Unfunded Property to be released, after making certain adjustments, does not exceed the lower of the Net Cost or Net Fair Value of all property acquired, made or constructed on or after 90 days before our request, after making certain adjustments. If neither (i) or (ii) in the immediately preceding sentence applies, we will be required to deliver a“make-up” amount in cash. We may apply as a credit against the cash we will be required to deliver to the Mortgage Trustee any of the items described under the bullet points in this section.

We also will be permitted to release in a calendar year property up to the lesser of $10 million (increased yearly by the urban CPI) or 3% of the aggregate principal amount of first mortgage bonds then outstanding without complying with the other release provisions in the Mortgage Indenture. However, if, upon reliance on this release provision, we release Funded Property, we are required to deposit with the Mortgage Trustee, by the end of the calendar year, cash equal to 70% of the Funded Property Basis of the property released, net of certain credits.

The Mortgage Indenture provides simplified procedures for the release of property taken by eminent domain, and provides for dispositions of certain obsolete property and grants or surrender of certain rights without any release or consent by the Mortgage Trustee.

The provisions described above permitting the release of property (except property taken by eminent domain) will be operable only if no Event of Default has occurred and is continuing under the Mortgage Indenture.

Withdrawal of Cash

Unless an Event of Default has occurred and is continuing and subject to certain limitations, cash held by the Mortgage Trustee may, generally,

• be withdrawn by us (i) to the extent of an amount equal to the Net Cost or Net Fair Value to us (whichever is less) of Property Additions constituting Unfunded Property, after certain deductions and additions, primarily including adjustments to offset retirements (except that these adjustments need not be made if the Property Additions were acquired or made within 90 days before our request for withdrawal) or (ii) in an amount equal to ten-sevenths (10/7ths) of the aggregate principal amount of first mortgage bonds that we would be entitled to issue on the basis of retired first mortgage bonds (with the entitlement to that issuance being waived by operation of the withdrawal) or (iii) in an amount equal to ten-sevenths (10/7ths) of the aggregate principal amount of any outstanding first mortgage bonds delivered to the Mortgage Trustee; or

• upon our request, applied to (i) the purchase of first mortgage bonds or (ii) the payment (or provision for payment) at stated maturity of any first mortgage bonds or the redemption (or provision for redemption) of any first mortgage bonds which are redeemable.

41

Evidence to be Furnished to the Mortgage Trustee Under the Mortgage Indenture

We will demonstrate compliance with Mortgage Indenture provisions by providing written statements to the Mortgage Trustee from our officers or persons we select. For instance, we may select an engineer to provide a written statement regarding the value of property being certified or released or counsel regarding compliance with the Mortgage Indenture generally. In certain major matters, applicable law requires that an accountant, engineer or other expert must be independent. We must file a certificate each year with respect to our compliance with the conditions and covenants under the Mortgage Indenture.

Consolidation, Merger, Transfer of Mortgaged Property

We may not consolidate with or merge with or into any other Person (as described below) or convey, otherwise transfer or lease all or substantially all of our Mortgaged Property to any Person unless:

• the Person formed by that consolidation or into which we are merged or the Person which acquires by conveyance or other transfer, or which leases, all or substantially all of the Mortgaged Property is a corporation, partnership, limited liability company, association, company, joint stock company or business trust, organized and existing under the laws of the United States, or any state thereof or the District of Columbia;

• that Person executes and delivers to the Mortgage Trustee a supplemental Mortgage Indenture that in the case of a consolidation, merger, conveyance or other transfer, or in the case of a lease if the term thereof extends beyond the last stated maturity of the first mortgage bonds then outstanding, contains an assumption by the successor Person of the due and punctual payment of the principal of and premium, if any, and interest, if any, on all first mortgage bonds then outstanding and the performance and observance of every covenant and conditions under the Mortgage Indenture to be performed or observed by us;

• that Person executes and delivers to the Mortgage Trustee a supplemental Mortgage Indenture that contains a grant, conveyance, transfer and mortgage by the successor Person confirming the lien of the Mortgage Indenture on the Mortgaged Property and subjecting to the lien all property (other than Excepted Property) thereafter acquired by the successor Person that shall constitute an improvement, extension or addition to the Mortgaged Property or renewal, replacement or substitution of or for any part thereof and, at the election of the successor Person, subjecting to the lien of the Mortgage Indenture the other property, real, personal and mixed, then owned or thereafter acquired by the Person as the person shall specify in its sole discretion;

• in the case of a lease, the lease is made expressly subject to termination by us at any time during the continuance of an Event of Default and by the purchaser of the property so leased at any sale of the property under the Mortgage Indenture, whether under the power of sale conferred by the Mortgage Indenture or pursuant to judicial proceedings;

• immediately after giving effect to the transaction and treating any indebtedness that becomes our obligation as a result of the transaction as having been incurred by us at the time of the transaction, no default or Event of Default shall have occurred and be continuing; and

• we have delivered to the Mortgage Trustee an officer’s certificate and an opinion of counsel, each stating that the merger, consolidation, conveyance, lease or transfer, as the case may be, fully complies with all provisions of the Mortgage Indenture; provided, however, that the delivery of the officer’s certificate and opinion of counsel shall not be required with respect to any merger, consolidation, conveyance, transfer or lease between us and any of our wholly-owned subsidiaries.

Notwithstanding the foregoing, we may merge or consolidate with or transfer all or substantially all of our assets to an affiliate that has no significant assets or liabilities and was formed solely for the purpose of changing our jurisdiction of organization or our form of organization or for the purpose of forming a holding company; provided that the amount of our indebtedness is not increased; and provided, further, that the successor assumes all of our obligations under the Mortgage Indenture.

42

In the case of a conveyance or other transfer of all or substantially all of the Mortgaged Property to any other Person as contemplated under the Mortgage Indenture, upon the satisfaction of all the conditions described above we (as we would exist without giving effect to the transaction) would be released and discharged from all obligations under the Mortgage Indenture and on the first mortgage bonds then outstanding unless we elect to waive the release and discharge.

The meaning of the term “substantially all” has not been definitively established and is likely to be interpreted by reference to applicable state law if and at the time the issue arises and will depend on the facts and circumstances existing at the time.

For purposes of this subsection:

• “Person” means any individual, corporation, limited liability partnership, joint venture, trust or unincorporated organization, or any other entity, whether or not a legal entity, or any Governmental Authority (as defined in the Mortgage Indenture).

Additional Covenants

We have agreed in the Mortgage Indenture, among other things:

• to maintain a place of payment for any series of first mortgage bonds; and

• to maintain our corporate existence (subject to the provisions above relating to mergers and consolidations).

Modification of the Mortgage Indentures; Waiver

We and the Mortgage Trustee may, with the consent of the holders of not less than a majority in aggregate principal amount of the first mortgage bonds of each affected series then outstanding under the Mortgage Indenture, considered as one class, modify or amend the Mortgage Indenture, including the provisions relating to the rights of the holders of first mortgage bonds of that series. However, no modification or amendment may, without the consent of each holder of affected first mortgage bonds:

• change the stated maturity of, the principal of, reduce the principal amount or any premium payable on, reduce the interest rate of, or change the method of calculating the interest rate with respect to that first mortgage bond;

• reduce the amount of principal payable upon acceleration of the maturity of that first mortgage bond;

• change the type of consideration (coin, currency or other property) used to pay the principal of, or interest or premium on that first mortgage bond;

• impair the right to institute suit for the enforcement of any payment on, or with respect to, that first mortgage bond;

• reduce the percentage in principal amount of outstanding first mortgage bonds of any series the consent of whose holders is required for modification or amendment of the Mortgage Indenture;

• reduce the percentage of principal amount of outstanding first mortgage bonds necessary for waiver of compliance with certain provisions of the Mortgage Indenture or for waiver of certain defaults;

• modify the provisions with respect to modification and waiver, except as provided in the Mortgage Indenture;

• reduce the quorum or voting requirements applicable to holders of the first mortgage bonds; or

• permit the creation of any lien (not otherwise permitted by the Mortgage Indenture) ranking prior to the lien of the Mortgage Indenture, with respect to all or substantially all of the Mortgaged Property or, except as otherwise expressly permitted under the Mortgage Indenture, release the lien of the Mortgage Indenture, terminate the lien of the Mortgage Indenture on all or substantially all of the Mortgaged Property or deprive the holders of the first mortgage bonds of the benefit of the lien of the Mortgage Indenture.

43

The holders of not less than a majority in aggregate principal amount of the first mortgage bonds of each affected series then outstanding under the Mortgage Indenture, voting as a single class, may waive compliance by us with certain provisions of the Mortgage Indenture benefiting holders of first mortgage bonds of that series or the applicable first mortgage bonds. The holders of not less than a majority in aggregate principal amount of the first mortgage bonds of any series outstanding under the Mortgage Indenture may, on behalf of the holders of all of the first mortgage bonds of that series, waive any past default under the Mortgage Indenture with respect to that series and its consequences, except defaults in the payment of the principal of or any premium or interest on any first mortgage bonds of that series and defaults in respect of a covenant or provision in the Mortgage Indenture which cannot be modified, amended or waived without the consent of each holder of affected first mortgage bonds.

We and the Mortgage Trustee may, without the consent of any holder of first mortgage bonds, amend the Mortgage Indenture and the first mortgage bonds for certain reasons, including, but not limited to, the following:

• to evidence the succession of another person to us and the assumption by any such successor of our covenants in the Mortgage Indenture and in the first mortgage bonds;

• add covenants or other provisions applicable to us and for the benefit of the holders of first mortgage bonds or one or more specified series thereof;

• establish the form or terms of first mortgage bonds of any series as contemplated by the Mortgage Indenture;

• cure any ambiguity;

• correct or amplify the description of the Mortgaged Property, or to subject to the lien of the Mortgage Indenture additional property (including property of persons other than us);

• specify any additional Permitted Liens with respect to that additional property;

• add, change or eliminate any provision of the Mortgage Indenture so long as the addition, change or elimination does not adversely affect the interest of holders of first mortgage bonds of any series in any material respect;

• change any place or places for payment or surrender of first mortgage bonds and where notices and demands to us may be served;

• comply with any requirement in connection with the qualification of the Indenture under the Trust Indenture Act; or

• comply with the rules of any applicable securities depository.

In order to determine whether the holders of the requisite principal amount of the outstanding first mortgage bonds have taken an action under the Mortgage Indenture as of a specified date:

• the principal amount of a discount bond that will be deemed to be outstanding will be the amount of the principal that would be due and payable as of that date upon acceleration of the maturity to that date; and

• first mortgage bonds owned by us or any other obligor upon the first mortgage bonds or any of our or their affiliates will be disregarded and deemed not to be outstanding.

Events of Default

An “Event of Default” means any of the following events which shall occur and be continuing:

• failure to pay interest on a first mortgage bond 60 days after such interest becomes due and payable; provided, however, that no such default shall constitute an “Event of Default” if we have made a valid extension of the interest payment period with respect to the first mortgage bonds of such series, of which such first mortgage bond is a party;

44

• failure to pay the principal of or sinking fund installment, if any, or premium, if any, on, any first mortgage bond within 3 Business Days after the same becomes due and payable; provided, however, that no such default shall constitute an “Event of Default” if we have made a valid extension of the maturity of the first mortgage bonds of the series of which such first mortgage bond is a party;

• failure to perform any other covenant or warranty applicable to us in the Mortgage Indenture continuing for 90 days after the Mortgage Trustee, or the holders of at least 25% in aggregate principal amount of the first mortgage bonds then outstanding, give us notice of the default and require us to remedy the default, unless the Mortgage Trustee, or the Mortgage Trustee and holders of a principal amount of first mortgage bonds not less than the principal amount of first mortgage bonds the holders of which gave that notice agree in writing to an extension of the period prior to its expiration; provided, however, that the Mortgage Trustee, or the Mortgage Trustee and the holders of such principal amount of first mortgage bonds, as the case may be, shall be deemed to have agreed to an extension of such period if corrective action is initiated by us within such period and is being diligently pursued;

• certain events of bankruptcy, insolvency or reorganization; and

• the occurrence of any Event of Default as defined in any mortgage, mortgage indenture or instrument under which there may be issued, or by which there may be secured or evidenced, any of our Debt (as defined below), whether the Debt exists on the date of execution of the Mortgage Indenture, or shall thereafter be created, if the Event of Default: (i) is caused by a failure to pay principal after final maturity of the Debt after the expiration of the grace period provided in the Debt (which we refer to as a “payment default”), or (ii) results in the acceleration of the Debt prior to its express maturity, and in each case, the principal amount of any of that Debt, together with the principal amount of any other Debt under which there has been a payment default or the maturity of which has been so accelerated, aggregates $200 million or more, provided, however, that if the Event of Default under that mortgage, Mortgage Indenture or instrument is cured or waived or the acceleration is rescinded or the Debt is repaid, within a period of 20 days from the continuation of that Event of Default beyond the applicable grace period or the occurrence of the acceleration, as the case may be, the Event of Default described in this bullet point shall be automatically cured; provided, further, that with respect to any mortgage, mortgage indenture or instrument that exists on the date of execution of the Mortgage Indenture, this provision only applies to the extent that the obligations to pay amounts thereunder are enforceable after the effective date of the Plan.

The $200 million amount specified in the bullet point above shall be increased in any calendar year subsequent to 2020 by the same percentage increase in the urban CPI Index (as defined in the Mortgage Indenture) for the period commencing January 1, 2020 and ending on January 1 of the applicable calendar year.

For purposes of this subsection, “Debt” means any debt of us for money borrowed and guarantees by us of debt for money borrowed but in each case excluding liabilities in respect of Lease Obligations or Swap Agreements. “Lease Obligation” means, at the time any determination is to be made, the amount of the liability in respect of a capital lease that would at that time be required to be capitalized on a balance sheet in accordance with GAAP. “Swap Agreement” means any agreement with respect to any swap, forward, future or derivative transaction or option or similar agreement involving, or settled by reference to, one or more rates, currencies, commodities, equity or debt instruments or securities, or economic, financial or pricing indices or measures of economic, financial or pricing risk or value or any similar transaction or any combination of these transactions.

If the Mortgage Trustee deems it to be in the interest of the holders of the first mortgage bonds, it may withhold notice of default, except defaults in the payment of principal, premium or interest with respect to any first mortgage bond.

45

If an Event of Default occurs, the Mortgage Trustee or the holders of at least 25% in aggregate principal amount of the first mortgage bonds outstanding, considered as one class, may declare all principal (or, if any of the first mortgage bonds are Discount Bonds (as such term is defined in the Mortgage Indenture), such portion of the principal amount of such first mortgage bonds as may be specified in the terms thereof) immediately due and payable, provided, however, that if an Event of Default occurs with respect to certain events of bankruptcy, insolvency or reorganization, then the principal amount (or, if any of the first mortgage bonds are Discount Bonds, such portion of the principal amount of such first mortgage bonds as may be specified in the terms thereof) of first mortgage bonds outstanding shall be due and payable immediately without further action by the Mortgage Trustee or holders. If the default has been cured and other specified conditions in the Mortgage Indenture have been satisfied before any Mortgaged Property has been sold and before a judgment or decree for payment has been obtained by the Mortgage Trustee as provided in the Mortgage Indenture, the event or events of default giving rise to the acceleration will be deemed to have been cured and the declaration of acceleration and its effect will be deemed to have been rescinded and annulled.

No holder of first mortgage bonds will have any right to institute any proceeding, judicial or otherwise, or for any other remedy under the Mortgage Indenture unless the holder has given the Mortgage Trustee written notice of the Event of Default, the holders of at least 25% of the first mortgage bonds have requested the Mortgage Trustee in writing to institute proceedings with respect to the Event of Default in its own name as Mortgage Trustee under the Mortgage Indenture and have offered the Mortgage Trustee reasonable indemnity against costs, expenses and liabilities with respect to the request, the Mortgage Trustee has failed to institute any proceeding within 60 days after receiving the notice from holders, and no direction inconsistent with the written request has been given to the Mortgage Trustee during the60-day period by holders of at least a majority in aggregate principal amount of first mortgage bonds then outstanding.

The Mortgage Trustee is not required to risk its funds or to incur financial liability if there is a reasonable ground for believing that repayment to it or adequate indemnity against risk or liability is not reasonably assured.

If an Event of Default has occurred and is continuing, holders of a majority in principal amount of the first mortgage bonds may establish the time, method and place of conducting any proceedings for any remedy available to the Mortgage Trustee, or exercising any trust or power conferred upon the Mortgage Trustee.

Discharge

Any first mortgage bond, or any portion of the principal amount thereof, will be deemed to have been paid for purposes of the Mortgage Indenture, and, at our election, our entire indebtedness in respect of the first mortgage bonds will be deemed to have been satisfied and discharged, if certain conditions are satisfied, including an irrevocable deposit with the Mortgage Trustee or any paying agent (other than us), in trust of:

• money (including funded cash not otherwise applied pursuant to the Mortgage Indenture) in an amount which will be sufficient, or

• in the case of a deposit made prior to the maturity of the first mortgage bonds or portions thereof, Eligible Obligations (as described below) which do not contain provisions permitting the redemption or other prepayment thereof at the option of the issuer thereof, the principal of and the interest on which when due, without any regard to reinvestment thereof, will provide monies which, together with the money, if any, deposited with or held by the Mortgage Trustee or the paying agent, will be sufficient, or

• a combination of either of the two items described in the two preceding bullet points which will be sufficient,

to pay when due the principal of and premium, if any, and interest, if any, due and to become due on the first mortgage bonds or portions thereof.

46

For purposes of this subsection, “Eligible Obligations” include direct obligations of, or obligations unconditionally guaranteed by, the United States of America, entitled to the benefit of the full faith and credit thereof, and depositary receipts or other instruments with respect to the obligations or any specific interest or principal payments due in respect thereof.

Transfer and Exchange

Subject to the terms of the Mortgage Indenture, first mortgage bonds of any series may be exchanged for other first mortgage bonds of the same series of any authorized denominations and of a like aggregate principal amount and tenor. Subject to the terms of the Mortgage Indenture and the limitations applicable to global securities, first mortgage bonds may be presented for exchange or registration of transfer at the office of the registrar without service charge, upon payment of any taxes and other governmental charges. Such transfer or exchange will be effected upon the Mortgage Trustee, us or the registrar, as the case may be, being satisfied with the documents of title and identity of the person making the request.

If we provide for any redemption of a series of first mortgage bonds in a prospectus supplement, we will not be required to execute, register the transfer of or exchange any first mortgage bond of that series for 15 days before a notice of redemption is given or register the transfer of or exchange any first mortgage bond selected for redemption.

Resignation or Removal of Mortgage Trustee

The Mortgage Trustee may resign at any time upon written notice to us but the Mortgage Trustee’s resignation will not take effect until a successor Mortgage Trustee accepts appointment. The Mortgage Trustee may be removed at any time by written notice delivered to the Mortgage Trustee and us and signed by the holders of at least a majority in principal amount of the outstanding first mortgage bonds. In addition, under certain circumstances, we may remove the Mortgage Trustee, or any holder who has been a bona fide holder of a first mortgage bond for at least six months may seek a court order for the removal of the Mortgage Trustee and the appointment of a successor trustee. We must give notice of resignation and removal of the Mortgage Trustee or the appointment of a successor trustee to all holders of first mortgage bonds as provided in the Mortgage Indenture.

Mortgage Trustee, Paying Agents and Registrars for the First Mortgage Bonds

The Bank of New York Mellon Trust Company, N.A. will serve as Mortgage Trustee under the Mortgage Indenture. We may change either the paying agent or registrar without prior notice to the holders of the first mortgage bonds, and we may act as paying agent. The Mortgage Trustee serves as trustee under our senior note Indenture. We and our parent company maintain ordinary banking and trust relationships with a number of banks and trust companies, including The Bank of New York Mellon Trust Company, N.A.

Governing Law

The Mortgage Indenture and the first mortgage bonds shall be governed by, and construed and enforced in accordance with, the laws of the State of New York (including without limitationSection 5-1401 of the New York General Obligations Law or any successor to such statute), except to the extent that the Trust Indenture Act shall be applicable, provided that the law of the jurisdiction in which the Mortgaged Property consisting of real property is located shall govern the creation of a mortgage lien on and security interest in, or perfection, priority or enforcement of the lien of the Mortgage Indenture or exercise of remedies with respect to, such portion of the Mortgaged Property.

DESCRIPTION OF COMMON STOCK AND PREFERRED STOCK

Unless indicated differently in a prospectus supplement, this section describes the terms of our common stock and preferred stock (together, the “capital stock”). The following description is only a summary and is qualified in its entirety by reference to applicable law, our restated articles of incorporation and bylaws and the Amended Articles (as defined below) and the Amended Bylaws (as defined below). In this section, references to “we,” “our,” “ours” and “us” refer only to PG&E Corporation and not to any of its direct or indirect subsidiaries or affiliates except as expressly provided.

In connection with PG&E Corporation’s and the Utility’s emergence from the Chapter 11 Cases, we expect to amend our restated articles of incorporation (the “Amended Articles”) and bylaws (the “Amended Bylaws”) to reflect certain changes in connection with the development and implementation of a plan of reorganization. The Amended Articles and the Amended Bylaws are subject to the approval of the Bankruptcy Court, and are therefore not in final form. Accordingly, the terms summarized below remain subject to change. In the event that the terms of the Amended Articles and/or the Amended Bylaws change after the effective date of this registration statement, we will update the following description in a prospectus supplement or post-effective amendment to this registration statement, in which case, the following description would be superseded by the description provided in such prospectus supplement or post-effective amendment to this registration statement. Copies of our current restated articles of incorporation and bylaws and the form of the Amended Articles and the Amended Bylaws are incorporated by reference as exhibits to the registration statement of which this prospectus is a part.

General

Our restated articles of incorporation authorize the issuance of 800,000,000 shares of common stock and 85,000,000 shares of preferred stock, and the Amended Articles will authorize the issuance of 3,600,000,000 shares of common stock and 400,000,000 shares of preferred stock. As of April 27, 2020, there were approximately 529,785,896 shares of our common stock, no par value, outstanding and no shares of preferred stock outstanding. All outstanding shares of our common stock are fully paid and nonassessable.

Common Stock

We may issue our common stock from time to time upon such terms and for such consideration as may be determined by our board of directors. Such further issuances, up to the aggregate amounts authorized by our restated articles of incorporation or the Amended Articles (once effective) will not require approval by our shareholders. We may also issue common stock from time to time under dividend reinvestment and employee benefit plans.

The Amended Articles (once effective) will restrict our ability to issue non-voting shares of our capital stock to the extent prohibited by Section 1123(a)(6) of the Bankruptcy Code for so long as such Section is in effect and applicable to us (the “Voting Restrictions”). Except as otherwise provided by law, holders of our common stock have voting rights on the basis of one vote per share on each matter submitted to a vote at a meeting of shareholders, subject to any class or series voting rights of holders of our preferred stock. Our shareholders may not cumulate votes in elections of directors. 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.

Holders of our common stock, subject to any prior rights or preferences of preferred stock outstanding, have equal rights to receive dividends if and when declared by our board of directors out of funds legally available therefor.

48

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. Additionally, the rights of holders of common stock may be materially limited or qualified by the rights of holders of preferred stock that we may issue in the future.

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

The transfer agent and registrar for our common stock is EQ Shareowner Services, P. O. Box 64874, St. Paul, MN, 55164-0874.

Preferred Stock

Our board of directors is authorized to issue shares of preferred stock in one or more series up to the aggregate amounts authorized by our restated articles of incorporation or the Amended Articles (once effective) and to fix and determine the number of shares of preferred stock of any series, to determine the designation of any such series, to increase or decrease the number of shares of any such series subsequent to the issue of shares of that series, and to determine or alter the rights, preferences, privileges and restrictions granted to or imposed upon any such series. Currently there are no shares of our preferred stock outstanding.

Prior to the issuance of shares of each series of our preferred stock, our board of directors is required to adopt resolutions and file a certificate of determination with the Secretary of State of the State of California. The certificate of determination will fix for each series the designation and number of shares and the rights, preferences, privileges and restrictions of the shares including, but not limited to, the following:

• the title and stated value of the preferred stock;

• voting rights, if any, of the preferred stock (in accordance with the Voting Restrictions, if applicable);

• any rights and terms of redemption (including sinking fund provisions);

• the dividend rate(s), period(s) and/or payment date(s) or method(s) of calculation applicable to the preferred stock;

• whether dividends are cumulative ornon-cumulative and, if cumulative, the date from which dividends on the preferred stock will accumulate;

• the relative ranking and preferences of the preferred stock as to dividend rights and rights upon the liquidation, dissolution or winding up of our affairs;

• the terms and conditions, if applicable, upon which the preferred stock will be convertible into our common stock, including the conversion price (or manner of calculation) and conversion period;

• the provision for redemption, if applicable, of the preferred stock;

• the provisions for a sinking fund, if any, for the preferred stock;

• liquidation preferences;

• any limitations on issuance of any class or series of preferred stock ranking senior to or on a parity with the class or series of preferred stock as to dividend rights and rights upon liquidation, dissolution or winding up of our affairs; and

• any other specific terms, preferences, rights, limitations or restrictions of the preferred stock.

49

All shares of preferred stock will, when issued, be fully paid and nonassessable and will not have any preemptive or similar rights.

In addition to the terms listed above, we will set forth in a prospectus supplement the following terms relating to the class or series of preferred stock being offered:

• the number of shares of preferred stock offered, the liquidation preference per share and the offering price of the preferred stock;

• the procedures for any auction and remarketing, if any, for the preferred stock;

• any listing of the preferred stock on any securities exchange; and

• a discussion of any material and/or special United States federal income tax considerations applicable to the preferred stock.

Until our board of directors determines the rights of the holders of a series of preferred stock, we cannot predict the effect of the issuance of any shares of preferred stock upon the rights of holders of our common stock. However, the effect could include one or more of the following:

• restricting dividends on our common stock;

• diluting the voting power of our common stock;

• impairing the liquidation rights of our common stock; or

• delaying or preventing a change in control of us without further action by our shareholders.

Rank

If issued, the preferred stock would rank, with respect to dividends and upon our liquidation, dissolution or winding up:

• senior to all classes or series of our common stock and to all of our equity securities ranking junior to the preferred stock;

• on a parity with all of our equity securities the terms of which specifically provide that the equity securities rank on a parity with the preferred stock; and

• junior to all of our equity securities the terms of which specifically provide that the equity securities rank senior to the preferred stock.

Ownership Restrictions

The Amended Articles will impose certain restrictions on the transferability and ownership of our capital stock and any other interests designated as “stock” of PG&E Corporation by the Board as disclosed in an SEC filing by PG&E Corporation (such stock and other interests, the “Equity Securities,” and such restrictions on transferability and ownership, the “Ownership Restrictions”) in order to reduce the possibility of an equity ownership shift that could result in limitations on our ability to utilize net operating loss carryforwards and other tax attributes from prior taxable years for Federal income tax purposes. Any acquisition of our capital stock that results in a shareholder being in violation of these restrictions may not be valid. The Ownership Restrictions may be waived by our board of directors on a case-by-case basis.

Subject to certain exceptions, the Ownership Restrictions will restrict (i) any person or entity (including certain groups of persons) from directly or indirectly acquiring or accumulating 4.75% or more of our outstanding Equity Securities and (ii) the ability of any person or entity (including certain groups of persons) already owning, directly or indirectly, 4.75% or more of our Equity Securities from increasing their proportionate

50

interest in our Equity Securities. Any transferee receiving Equity Securities that would result in a violation of the Ownership Restrictions will not be recognized as a shareholder of PG&E Corporation or entitled to any rights of shareholders, including, without limitation, the right to vote and to receive dividends or distributions, whether liquidating or otherwise, in each case, with respect to the Equity Securities causing the violation.

The Ownership Restrictions will remain in effect until the earliest of (i) the repeal, amendment or modification of Section 382 (and any comparable successor provision) of the Code, in such a way as to render the restrictions imposed by Section 382 of the Code no longer applicable to PG&E Corporation, (ii) the beginning of a taxable year in which our board of directors determines that no tax benefits attributable to net operating losses or other tax attributes are available, (iii) the date selected by our board of directors if it determines that the limitation amount imposed by Section 382 of the Code as of such date in the event of an “ownership change” of PG&E Corporation (as defined in Section 382 of the Code and Treasury Regulation Sections 1.1502-91et seq.) would not be materially less than the net operating loss carryforwards or “net unrealized built-in loss” (within the meaning of Section 382 of the Code and Treasury Regulation Sections 1.1502-91et seq.) of PG&E Corporation and (iv) the date selected by our board of directors if it determines that it is in the best interests of our shareholders for the Ownership Restrictions to be removed or released.

This prospectus and any accompanying prospectus supplement will contain the material terms and conditions for each securities purchase contract and securities purchase unit. The accompanying prospectus supplement may add, update or change the terms and conditions of the securities purchase contracts and securities purchase units as described in this prospectus.

Stock Purchase Contracts and Stock Purchase Units

PG&E Corporation may issue stock purchase contracts, representing contracts obligating holders to purchase from or sell to it, and obligating it to sell to or purchase from the holders, a specified number of shares of common stock or preferred stock at a future date or dates, or a variable number of shares of common stock or preferred stock for a stated amount of consideration. The price per share and the number of shares of common stock or preferred stock may be fixed at the time the stock purchase contracts are issued or may be determined by reference to a specific formula set forth in the stock purchase contracts. Any such formula may include antidilution provisions to adjust the number of shares of common stock or preferred stock issuable pursuant to the stock purchase contracts upon certain events.

The stock purchase contracts may be issued separately or as a part of units consisting of a stock purchase contract and either:

(i) senior or subordinated debt securities of PG&E Corporation; or

(ii) debt obligations of third parties, including U.S. Treasury securities, which, in either case, may or may not serve as security for the holder’s obligations to purchase or sell the shares under the stock purchase contracts.

The stock purchase contracts may require PG&E Corporation to make periodic payments to the holders of the stock purchase units or vice versa, and such payments may be unsecured or prefunded on some basis. The stock purchase contracts may require holders to secure their obligations in a specified manner and in certain circumstances PG&E Corporation may deliver newly issued prepaid stock purchase contracts upon release to a holder of any collateral securing such holder’s obligations under the original stock purchase contract.

Ownership of stock purchase contracts and exercise by holders thereof may be subject to certain limitations in accordance with the Ownership Restrictions described in the section entitled “Description of Common Stock and Preferred Stock—Ownership Restrictions” in this prospectus.

Debt Purchase Contracts and Debt Purchase Units

We may issue debt purchase contracts, representing contracts obligating holders to purchase from us, and obligating us to sell to the holders, a specified principal amount of debt securities at a future date or dates. The purchase price and the interest rate may be fixed at the time the debt purchase contracts are issued or may be determined by reference to a specific formula set forth in the debt purchase contracts.

The debt purchase contracts may be issued separately or as a part of units consisting of debt purchase contracts and either:

(i) senior or subordinated debt securities of PG&E Corporation; or

(ii) debt obligations of third parties, including U.S. Treasury securities, which, in either case, may or may not serve as security for the holder’s obligations to purchase the securities under the debt purchase contracts.

The debt purchase contracts may require us to make periodic payments to the holders of the debt purchase units or vice versa, and such payments may be unsecured or prefunded on some basis. The debt purchase contracts

55

may require holders to secure their obligations in a specified manner and in certain circumstances we may deliver newly issued prepaid debt purchase contracts upon release to a holder of any collateral securing such holder’s obligations under the original debt purchase contract.

The applicable prospectus supplement will describe the general terms of any purchase contracts or purchase units and, if applicable, prepaid purchase contracts. The description in the prospectus supplement will not purport to be complete and will be qualified in its entirety by reference to:

• the purchase contracts;

• the collateral, depositary and custodial arrangements, if applicable, relating to such purchase contracts or purchase units; and

• if applicable, the prepaid purchase contracts and the document pursuant to which such prepaid purchase contracts will be issued.

Material United States federal income tax considerations applicable to the purchase contracts and the purchase units will also be discussed in the applicable prospectus supplement.

DESCRIPTION OF DEPOSITARY SHARES

This section describes the general terms of the depositary shares we may offer and sell by this prospectus. This prospectus and any accompanying prospectus supplement will contain the material terms and conditions for the depositary shares. The accompanying prospectus supplement may add, update, or change the terms and conditions of the depositary shares as described in this prospectus. In this section, references to “we,” “our,” “ours” and “us” refer only to PG&E Corporation and not to any of its direct or indirect subsidiaries or affiliates except as expressly provided.

We may, at our option, elect to offer depositary shares, each representing a fraction (to be set forth in the prospectus supplement relating to a particular series of preferred stock) of a share of a particular class or series of preferred stock as described below. In the event we elect to do so, depositary receipts evidencing depositary shares will be issued to the public.

The shares of any class or series of preferred stock represented by depositary shares will be deposited under a deposit agreement between us and one or more depositaries selected by us. Subject to the terms of the deposit agreement, each owner of a depositary share will be entitled, in proportion to the applicable fraction of a share of preferred stock represented by such depositary share, to all the rights and preferences of the shares of preferred stock represented by the depositary share, including dividend, voting, redemption and liquidation rights.

The depositary shares will be evidenced by depositary receipts issued pursuant to the deposit agreement. Depositary receipts will be distributed to those persons purchasing the fractional shares of the related class or series of preferred shares in accordance with the terms of the offering described in the related prospectus supplement.

The depositary shares may be subject to certain limitations in accordance with the Ownership Restrictions described in the section entitled “Description of Common Stock and Preferred Stock—Ownership Restrictions” in this prospectus.

DESCRIPTION OF SUBSCRIPTION RIGHTS

This section describes the general terms of the subscription rights that we may offer and sell by this prospectus. This prospectus and any accompanying prospectus supplement will contain the material terms and conditions for each subscription right. The accompanying prospectus supplement may add, update or change the terms and conditions of the subscription rights as described in this prospectus.

In this section, references to “we,” “our,” “ours” and “us” refer only to PG&E Corporation and not to any of its direct or indirect subsidiaries or affiliates except as expressly provided.

General

We may issue subscription rights to purchase common stock. Subscription rights may be issued independently or together with any other offered security and may or may not be transferable by the person purchasing or receiving the subscription rights. In connection with any subscription rights offering to our shareholders, we may enter into backstop commitment letters or other standby purchase arrangements with one or more parties pursuant to which such parties will purchase any offered securities remaining unsubscribed for after such subscription rights offering. In connection with a subscription rights offering to our shareholders, we will distribute a prospectus supplement to our shareholders on the record date that we set for receiving subscription rights in such subscription rights offering.

The applicable prospectus supplement will describe the terms of any subscription rights in respect of which this prospectus is being delivered, including the following:

• the title of the subscription rights;

• the exercise price for the subscription rights;

• the number of the subscription rights issuable to each rightholder;

• the extent to which the subscription rights will be transferable;

• the date on which the right to exercise the subscription rights will commence and the date on which the rights will expire (subject to any extension);

• the extent to which the rights will include an over-subscription privilege with respect to unsubscribed securities;

• if applicable, the material terms of any backstop commitment letters or other standby purchase arrangements that we may enter into in connection with the subscription rights offering;

• if applicable, a discussion of the material United States federal income tax considerations applicable to the issuance or exercise of the subscription rights; and

• any other terms of the subscription rights, including terms, procedures and limitations relating to the exchange and exercise of the subscription rights.

Exercise of Subscription Rights

Each subscription right will entitle the holder of the subscription right to purchase for cash such amount of shares of our common stock at such exercise price as shall in each case be set forth in, or be determinable as set forth in, the prospectus supplement relating to the subscription rights offered thereby. Subscription rights may be exercised at any time up to the close of business on the expiration date for such subscription rights set forth in the prospectus supplement. After the close of business on the expiration date, all unexercised subscription rights will become void.

58

Subscription rights may be exercised as set forth in the prospectus supplement relating to the subscription rights offered thereby. The prospectus supplement for any issuance of subscription rights will describe the procedures for payment of the applicable subscription price and the settlement of the subscription rights that are exercised, including the terms of any applicable escrow arrangements. We may determine to offer any unsubscribed offered securities directly to persons other than shareholders, to or through agents, underwriters or dealers or through a combination of such methods, including pursuant to backstop commitment letters or other standby purchase arrangements, as set forth in the applicable prospectus supplement.

Ownership of subscription rights and exercise by holders thereof may also be subject to certain limitations in accordance with the Ownership Restrictions described in the section entitled “Description of Common Stock and Preferred Stock—Ownership Restrictions” in this prospectus.

59

GLOBAL SECURITIES

Book-Entry, Delivery and Form

Unless we indicate differently in a prospectus supplement, the debt securities, common stock, preferred stock, warrants, securities purchase contracts, securities purchase units or depositary shares initially will be issued in book entry form and represented by one or more global notes or global securities (collectively, “global securities”). The global securities will be deposited with, or on behalf of, The Depository Trust Company, New York, New York, as depositary (“DTC”), and registered in the name of Cede & Co., the nominee of DTC. Unless and until it is exchanged for individual certificates evidencing securities under the limited circumstances described below, a global security may not be transferred except as a whole by the depositary to its nominee or by the nominee to the depositary, or by the depositary or its nominee to a successor depositary or to a nominee of the successor depositary.

DTC has advised us that it is:

• a limited-purpose trust company organized under the New York Banking Law;

• a “banking organization” within the meaning of the New York Banking Law;

• a member of the Federal Reserve System;

• a “clearing corporation” within the meaning of the New York Uniform Commercial Code; and

• a “clearing agency” registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

DTC holds securities that its participants deposit with DTC. DTC also facilitates the settlement among its participants of securities transactions, including transfers and pledges, in deposited securities through electronic computerized book-entry changes in participants’ accounts, which eliminates the need for physical movement of securities certificates. “Direct participants” in DTC include securities brokers and dealers, including underwriters, banks, trust companies, clearing corporations and other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is the holding company for DTC National Securities Clearing Corporation, all of which are registered clearing agencies. DTC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others, referred to as “indirect participants,” that clear transactions through or maintain a custodial relationship with a direct participant either directly or indirectly. The rules applicable to DTC and its participants are on file with the SEC.

Purchases of securities within the DTC system must be made by or through direct participants, which will receive a credit for those securities on DTC’s records. The ownership interest of the actual purchaser of a security, which we sometimes refer to as a “beneficial owner,” is in turn recorded on the direct and indirect participants’ records. Beneficial owners of securities will not receive written confirmation from DTC of their purchases. However, beneficial owners are expected to receive written confirmations providing details of their transactions, as well as periodic statements of their holdings, from the direct or indirect participants through which they purchased securities. Transfers of ownership interests in global securities are to be accomplished by entries made on the books of participants acting on behalf of beneficial owners. Beneficial owners will not receive certificates representing their ownership interests in the global securities except under the limited circumstances described below.

To facilitate subsequent transfers, all global securities deposited by direct participants with DTC will be registered in the name of DTC’s partnership nominee, Cede & Co, or such other name as may be requested by an authorized representative of DTC. The deposit of securities with DTC and their registration in the name of Cede & Co. or such other nominee do not affect any change in beneficial ownership. DTC has no knowledge of the actual beneficial owners of the securities. DTC’s records reflect only the identity of the direct participants to whose accounts the securities are credited, which may or may not be the beneficial owners. The direct and indirect participants are responsible for keeping account of their holdings on behalf of their customers.

60

Conveyance of notices and other communications by DTC to direct participants, by direct participants to indirect participants and by direct participants and indirect participants to beneficial owners will be governed by arrangements among them, subject to any legal requirements in effect from time to time. Beneficial owners of securities may wish to take certain steps to augment the transmission to them of notices of significant events with respect to the securities, such as redemptions, tenders, defaults, and proposed amendments to the security documents. For example, beneficial owners of securities may wish to ascertain that the nominee holding the securities for their benefit has agreed to obtain and transmit notices to beneficial owners. In the alternative, beneficial owners may wish to provide their names and addresses to the registrar and request that copies of notices be provided directly to them.

Redemption notices will be sent to DTC or its nominee. If less than all of the securities of a particular series are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each direct participant in such issue to be redeemed.

In any case where a vote may be required with respect to securities of a particular series, neither DTC nor Cede & Co. (nor any other DTC nominee) will give consents for or vote the global securities, unless authorized by a direct participant in accordance with DTC’s procedures. Under its usual procedures, DTC will send an omnibus proxy to us as soon as possible after the record date. The omnibus proxy assigns the consenting or voting rights of Cede & Co. to those direct participants to whose accounts the securities of such series are credited on the record date identified in a listing attached to the omnibus proxy.

Principal and interest payments on the securities will be made to Cede & Co., or such other nominee as may be requested by authorized representative of DTC. DTC’s practice is to credit direct participants’ accounts upon receipt of funds and corresponding detail information from us or the paying agent in accordance with their respective holdings shown on DTC’s records. Payments by direct and indirect participants to beneficial owners will be governed by standing instructions and customary practices, as is the case with securities held for the account of customers in bearer form or registered in “street name.” Those payments will be the responsibility of participants and not of DTC, the paying agent or us, subject to any legal requirements in effect from time to time. Payment of principal and interest to Cede & Co. (or such other nominee as may otherwise be requested by an authorized representative of DTC) is our responsibility, disbursement of payments to direct participants is the responsibility of DTC and disbursement of payments to the beneficial owners is the responsibility of direct and indirect participants.

Except under the limited circumstances described below, purchasers of securities will not be entitled to have securities registered in their names and will not receive physical delivery of securities. Accordingly, each beneficial owner must rely on the procedures of DTC and its participants to exercise any rights under the securities and the applicable indenture.

The laws of some jurisdictions may require that some purchasers of securities take physical delivery of securities in definitive form. Those laws may impair the ability to transfer or pledge beneficial interests in securities.

DTC may discontinue providing its services as securities depository with respect to the securities at any time by giving us reasonable notice. Under such circumstances, in the event that a successor securities depository is not obtained, certificates representing the securities are required to be printed and delivered. Also, we may decide to discontinue use of the system of book-entry-only transfers through DTC (or a successor securities depository), in which event, certificates representing the securities will be printed and delivered to DTC.

We have obtained the information in this section and elsewhere in this prospectus concerning DTC and DTC’s book-entry system from sources that are believed to be reliable, but we take no responsibility for the accuracy of this information.

61

PLAN OF DISTRIBUTION

We may sell the securities offered by this prospectus from time to time:

• to underwriters or dealers for resale to the public or to institutional investors;

• through agents to the public or to institutional investors;

• directly to one or more purchasers, shareholders or holders of subscription rights;

• in “at the market offerings” to or through a market maker or into an existing trading market, or in a rights offering or a securities exchange or otherwise; or

• through a combination of any of these methods or any other method permitted by law.

This prospectus may be used in connection with any offering of our securities through any of these methods or other methods described in the applicable prospectus supplement. The distribution of our securities may be effected from time to time in one or more transactions:

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

• at market prices prevailing at the time of sale;

• at prices related to such prevailing market prices; or

• at negotiated prices.

We may directly solicit offers to purchase securities, or agents may be designated to solicit such offers. The prospectus supplement with respect to the securities we may sell will set forth the terms of the offering of such securities, including the name or names of any underwriters or agents, the purchase price of such securities, and the proceeds to us from such sale, any underwriting discounts or agency fees and other items constituting underwriters’ or agents’ compensation, any initial public offering price, any discounts or concessions allowed or reallowed or paid to dealers and any securities exchange on which such securities may be listed.

If underwriters participate in the sale, such securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price, at market prices prevailing at the time of sale, at prices based on prevailing market prices or at negotiated prices.

Securities may be offered to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more of those firms. The specific managing underwriter or underwriters, if any, will be named in the prospectus supplement relating to the particular securities together with the members of the underwriting syndicate, if any. Unless otherwise set forth in the applicable prospectus supplement, the obligations of the underwriters to purchase any series of the securities will be subject to certain conditions precedent and the underwriters will be obligated to purchase all of such series of securities, if any are purchased.

We may sell securities directly or through agents we designate from time to time. The prospectus supplement will set forth the name of any agent involved in the offer or sale of securities in respect of which such prospectus supplement is delivered and any commissions payable by us to such agent. Unless otherwise indicated in a prospectus supplement, any agent will be acting on a best efforts basis for the period of its appointment.

Any underwriters, dealers or agents participating in the distribution of securities may be deemed to be underwriters as defined in the Securities Act of 1933, as amended (the “Securities Act”), and any discounts or commissions received by them on the sale or resale of securities may be deemed to be underwriting discounts and commissions under the Securities Act. Underwriters and agents may be entitled under agreements entered

62

into with us to indemnification against certain civil liabilities, including liabilities under the Securities Act. Underwriters and agents and their affiliates may engage in transactions with, or perform services for, us in the ordinary course of business.

Each series of debt securities, preferred stock, depositary shares, warrants, securities purchase contracts, securities purchase units and subscription rights, will be a new issue of securities and will have no established trading market. Any underwriters to whom securities are sold for public offering and sale may make a market in such securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice. The debt securities, preferred stock, depositary shares, warrants, securities purchase contracts, securities purchase units and subscription rights may or may not be listed on a national securities exchange.

To facilitate a securities offering, any underwriter may engage in over-allotment, short covering transactions and penalty bids or stabilizing transactions in accordance with Regulation M under the Exchange Act.

• Over-allotment involves sales in excess of the offering size, which creates a short position.

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

• Short covering positions involve purchases of securities in the open market after the distribution is completed to cover short positions.

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

These activities may cause the price of the securities to be higher than it otherwise would be. If commenced, these activities may be discontinued by the underwriters at any time.

63
