The first part is this prospectus supplement, which describes the specific terms of the notes, the specific terms of this offering and supplements and updates information contained in the accompanying prospectus and the documents incorporated by reference into this prospectus supplement and the accompanying prospectus. The second part, the accompanying prospectus, provides more general information about the notes and other securities that may be offered from time to time using such prospectus, some of which general information does not apply to this offering. Generally, when we refer to the prospectus, we are referring to both parts of this document combined. You should read this prospectus supplement and the accompanying prospectus together with any written communication prepared by us or on our behalf in connection with this offering together with the additional information described in the accompanying prospectus under the heading “Where You Can Find More Information” and in this prospectus supplement under the headings “Where You Can Find More Information” and “Incorporation By Reference.”

We have not, and the underwriters have not, authorized anyone to provide any information or to make any representations other than those contained or incorporated by reference in this prospectus supplement, the accompanying prospectus and any written communication prepared by us or on our behalf. We and the underwriters take no responsibility for, and can provide no assurance as to the reliability of, any other information that others may give you. We are not, and the underwriters are not, making an offer to sell the notes and are not soliciting an offer to buy the notes in any jurisdiction where the offer or sale is not permitted. The information we have included in this prospectus supplement or the accompanying prospectus is accurate only as of the date of this prospectus supplement or the accompanying prospectus, as the case may be, and any information we have incorporated by reference is accurate only as of the date of the document incorporated by reference.

We expect that delivery of the notes offered hereby will be made against payment therefor on or about October            , 2020, which will be the            business day following the date of pricing of the notes (this settlement cycle being referred to as “T+            ”). Under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), trades in the secondary market generally are required to settle in two business days, unless the parties to a trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes on the initial pricing date of the notes or the next            succeeding business days will be required, by virtue of the fact that the notes initially will settle in T+            , to specify alternative settlement arrangements at the time of any such trade to prevent a failed settlement and should consult their own advisors.

SUMMARY

This summary highlights information from this prospectus supplement and the accompanying prospectus. It is not complete and may not contain all of the information that you should consider before investing in the notes. We encourage you to read this prospectus supplement, the accompanying prospectus and the documents incorporated by reference in their entirety before making an investment decision, including the information set forth under the heading “Risk Factors.” Unless the context requires otherwise, the terms “we,” “our,” and “us” refer to CenterPoint Energy Resources Corp. and its subsidiaries, and the term “CenterPoint Energy” refers to CenterPoint Energy, Inc., our indirect parent.

The term “notes” refers to the         % Senior Notes due 2030.

CenterPoint Energy Resources Corp.

We are an indirect, wholly-owned subsidiary of CenterPoint Energy, a public utility holding company. Our divisions and operating subsidiaries include:

• our natural gas distribution business, through which we directly own and operate natural gas distribution systems in six states;

The Offering

Issuer CenterPoint Energy Resources Corp.

Notes Offered $             aggregate principal amount of             % senior notes due 2030

Maturity Date October 1, 2030

Interest Payment Dates April 1 and October 1, commencing on April 1, 2021

Ranking The notes will:

• be our general unsecured obligations;

• rank equally in right of payment with our other existing and future unsecured and unsubordinated indebtedness; and

• be structurally subordinated to the liabilities of our subsidiaries.

As of June 30, 2020, we, on an unconsolidated basis, had approximately $2.4 billion aggregate principal amount of indebtedness outstanding (inclusive of outstanding commercial paper), all of which was unsecured and unsubordinated.

Optional Redemption At any time and from time to time, we may redeem at our option in whole or in part the notes on any date prior to July 1, 2030 (the “Par Call Date”), by paying the greater of (i) 100% of the principal amount to be redeemed and (ii) the applicable “make-whole” amount based on U.S. treasury rates as specified in this prospectus supplement under “Description of the Notes — Optional Redemption” plus, in each case, accrued and unpaid interest thereon, if any, to, but excluding, the redemption date. At any time on or after the Par Call Date, we may redeem at our option in whole or in part the notes by paying 100% of the principal amount to be redeemed plus accrued and unpaid interest thereon, if any, to, but excluding, the redemption date. For additional information, please see “Description of the Notes — Optional Redemption” beginning on page S-9 of this prospectus supplement.

Consolidation, Merger and Sale of Assets The indenture restricts our ability to merge, consolidate or transfer substantially all of our assets. See “Description of Our Senior Debt Securities — Consolidation, Merger and Sale of Assets” on page 13 of the accompanying prospectus.

Lack of Public Market for the Notes There is no existing market for the notes. We cannot provide any assurance about:

• the liquidity of any markets that may develop for the notes;

• your ability to sell the notes; or

• the prices at which you will be able to sell the notes.

S-2

Future trading prices of the notes will depend on many factors, including:

• prevailing interest rates;

• our operating results;

• the ratings of the notes; and

• the market for similar securities.

We do not intend to apply for listing of the notes on any securities exchange or for quotation of the notes on any dealer quotation system.

Risk Factors You should consider carefully all the information set forth and incorporated by reference in this prospectus supplement and the accompanying prospectus and, in particular, you should evaluate the specific factors set forth under “Risk Factors” beginning on page S-5 of this prospectus supplement before deciding whether to invest in the notes.

Governing Law The indenture and the notes are governed by, and construed in accordance with, the laws of the State of New York.

Use of Proceeds The net proceeds from this offering, after deducting the underwriting discount and estimated expenses of the offering payable by us, are expected to be approximately $             . We intend to use the net proceeds from this offering for general corporate purposes, including the payment of a portion of the redemption amount of our outstanding 4.50% Senior Notes due 2021, Series A and B (the “2021 Notes”). The 2021 Notes have been called for redemption in full on October 15, 2020. As of September 21, 2020, approximately $593.0 million of the 2021 Notes were outstanding. Pending application of the net proceeds of this offering for the foregoing purposes, we expect to use the net proceeds to repay a portion of our commercial paper or invest such net proceeds in various instruments which may include, but would not be limited to, short-term, interest-bearing obligations, including bank deposits and certificates of deposit with financial institutions having investment-grade ratings, U.S. government obligations or money market funds primarily invested in securities issued by the U.S. government or its agencies. See “Use of Proceeds” in this prospectus supplement.

Conflicts of Interest One of the underwriters owns some of our commercial paper and as a result could receive greater than 5% of the net proceeds from this offering in connection with any such repayment, and would therefore be deemed to have a conflict of interest under Financial Industry Regulatory Authority (“FINRA”) Rule 5121. Consequently, this offering of notes must be conducted in compliance with the provisions of FINRA Rule 5121 and such underwriter or its affiliates will not be permitted to sell notes in this offering to accounts over which they exercise discretionary authority without the prior specific written approval of the account holders.

S-3

Minimum Denominations The notes will be issued in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

Trustee The Bank of New York Mellon Trust Company, N.A. (as successor to JPMorgan Chase Bank, National Association).

S-4

RISK FACTORS

You should consider carefully the risk factors, including those related to the novel coronavirus disease 2019 and related global outbreak that was subsequently declared a pandemic by the World Health Organization (“COVID-19”), identified in Part I, Item IA “Risk Factors” of our Annual Report on Form 10-K for the fiscal year ended December 31, 2019 (“2019 Form 10-K”) and in Part II, Item IA “Risk Factors” of our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2020 (“1st Quarter 2020 Form 10-Q”) and June 30, 2020 (“2nd Quarter 2020 Form 10-Q”), the following information about risks, as well as risks arising from any legal proceedings identified or referenced in Part II, Item 1 “Legal Proceedings” of our 1^st Quarter 2020 Form 10-Q and 2nd Quarter 2020 Form 10-Q and in “Legal Proceedings” in Part 1, Item 3 of our 2019 Form 10-K, as they may be amended, supplemented or superseded from time to time by other reports that we subsequently file with the Securities and Exchange Commission (the “SEC”), together with the other information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus, before making an investment in the notes.

Risks Related to the Notes

We cannot assure you that an active trading market will develop for the notes.

The notes will be a new issue of securities for which currently there is no established trading market. We do not intend to apply for the listing of the notes on any securities exchange or for quotation of the notes on any dealer quotation system. We cannot assure you that a trading market will develop for the notes. Even if a market for the notes does develop, we cannot assure you that there will be liquidity in that market or that such notes might not trade for less than their original value or face amount. The liquidity of any market for the notes will depend on the number of holders of such notes, the interest of securities dealers in making a market in such notes and other factors. If a liquid market for the notes does not develop, you may be unable to resell such notes for a long period of time, if at all. This means you may not be able to readily convert your notes into cash, and such notes may not be accepted as collateral for a loan.

Even if a market for the notes develops, trading prices could be higher or lower than the initial offering price. The price of such notes will depend on many factors, including prevailing interest rates, our operating results and the market for similar securities. Declines in the market prices for debt securities generally may also materially and adversely affect the liquidity of the notes, independent of our financial performance.

Our existing indebtedness, and any future indebtedness, may adversely affect our future financial and operating flexibility and our ability to service the notes.

As of June 30, 2020, we, on an unconsolidated basis, had approximately $2.4 billion aggregate principal amount of indebtedness outstanding (inclusive of outstanding commercial paper), all of which was unsecured and unsubordinated. Our existing indebtedness and the additional debt we may incur in the future for, among other things, working capital, capital expenditures, acquisitions or operating activities may adversely affect our liquidity and, therefore, our ability to make principal and interest payments on the notes.

The indenture governing the notes will permit us to incur additional debt, which would be equal in right of payment to the notes. If we incur any additional indebtedness, including trade payables, that ranks equally with the notes, the holders of that debt would be entitled to share ratably with you in any proceeds distributed in connection with any insolvency, liquidation, reorganization, dissolution or other winding up of us. This may have the effect of reducing the amount of proceeds paid to you. If new debt is added to our current debt levels, the related risks that we now face could intensify.

S-5

The notes will be structurally subordinated to existing and future indebtedness and other liabilities of our subsidiaries.

We hold a significant portion of our assets through our subsidiaries. As a result, we may depend on distributions from our subsidiaries to meet our payment obligations under any debt securities, including the notes and our other obligations. In general, these subsidiaries are separate and distinct legal entities and have no obligation to pay any amounts due on our debt securities or to provide us with funds for our payment obligations, whether by dividends, distributions, loans or otherwise. In addition, provisions of applicable law, such as those limiting the legal sources of dividends, limit our subsidiaries’ ability to make payments or other distributions to us, and our subsidiaries could agree to contractual restrictions on their ability to make distributions.

Our right to receive any assets of any subsidiary, and therefore the right of our creditors to participate in those assets, will be structurally subordinated to the claims of that subsidiary’s creditors, including trade creditors. In addition, even if we were a creditor of any subsidiary, our rights as a creditor would be subordinated to any security interest in the assets of that subsidiary and any indebtedness of the subsidiary senior to that held by us.

The provisions of the notes will not necessarily protect you in the event of a highly leveraged transaction.

The terms of the notes will not necessarily afford you protection in the event of a highly leveraged transaction that may adversely affect you, including a reorganization, recapitalization, restructuring, merger or other similar transactions involving us or our subsidiaries, whether or not in connection with a change of control. The indenture does not limit the amount of debt we or our subsidiaries may issue. As a result, we could enter into any such transaction even though the transaction could adversely affect our capital structure or credit ratings or otherwise adversely affect the holders of the notes. If we incur secured debt, the notes will be effectively junior to such debt to the extent of the value of the collateral securing such debt. The indenture does not contain provisions that permit the holders of the notes to require us to redeem or repurchase the notes in the event of a takeover, recapitalization or similar transaction.

Ratings of the notes may change and affect the market prices and marketability of the notes.

Our debt securities are subject to periodic review by one or more independent credit rating agencies and may be subject to rating and periodic review by additional independent credit rating agencies in the future. Any such ratings are limited in scope and do not address all material risks relating to an investment in the notes, but rather reflect only the view of the rating agency at the time the rating is issued. An explanation of the significance of such rating may be obtained from such rating agency. We cannot assure you that such credit rating will remain in effect for any given period of time or that any such rating will not be lowered, suspended or withdrawn entirely by the rating agency if, in such rating agency’s judgment, circumstances so warrant. It is also possible that any such rating may be lowered in connection with future events. Holders of notes will have no recourse against us or any other parties in the event of a change in or suspension or withdrawal of any such rating. Any lowering, suspension or withdrawal of such ratings may have an adverse effect on the market prices or marketability of the notes.

The indenture limits the ability of security holders to bring suit, waive defaults and amend the indenture.

The indenture provides that the consent of holders of certain minimum percentages of the aggregate principal amount of the notes outstanding under the indenture is required to waive certain defaults, bring suit and, with exceptions, amend the indenture. Your consent to such actions will not be effective unless consents are received from the holders of the required minimum amount of such notes. Further, even if you do not consent to such actions, those actions may still be taken if consented to by the holders of the required minimum amount of such notes.

Subject to certain limited exceptions, the indenture provides that the trustee or the holders of 33% or more in aggregate principal amount of the notes outstanding under the indenture may declare the principal amount of the notes to be due and payable immediately if an event of default shall occur and is continuing.

S-6

USE OF PROCEEDS

We expect the net proceeds from this offering to be approximately $                after deducting the underwriting discount and estimated expenses of the offering payable by us. We intend to use the net proceeds from this offering for general corporate purposes, including the payment of a portion of the redemption amount of our outstanding 4.50% Senior Notes due 2021, Series A and B (the “2021 Notes”). The 2021 Notes have been called for redemption in full on October 15, 2020. As of September 21, 2020, approximately $593.0 million of the 2021 Notes were outstanding. Pending application of the net proceeds of this offering for the foregoing purposes, we expect to repay a portion of our commercial paper, which were issued in part for general corporate and working capital purposes or invest such net proceeds in various instruments which may include, but would not be limited to, short-term, interest-bearing obligations, including bank deposits and certificates of deposit with financial institutions having investment-grade ratings, U.S. government obligations or money market funds primarily invested in securities issued by the U.S. government or its agencies. On June 30, 2020, we had $232.4 million of commercial paper borrowings, which had a weighted-average maturity of one day and a weighted-average interest rate of 0.26%.

CAPITALIZATION

The following table sets forth our consolidated short-term debt and capitalization as of June 30, 2020. No adjustments have been made for:

• the issuance of the notes in this offering or the use of proceeds therefrom, as discussed in “Use of Proceeds” above; or

• any changes in short-term debt after June 30, 2020.

This table should be read in conjunction with our consolidated financial statements and related notes thereto and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our Form 8-K filed on May 19, 2020 and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our 2nd Quarter 2020 Form 10-Q.

DESCRIPTION OF THE NOTES

The following description of the particular terms of the notes (referred to in the accompanying prospectus as the debt securities) supplements, and to the extent inconsistent therewith replaces, the description of the general terms and provisions of the debt securities set forth in the accompanying prospectus, to which we refer you.

We will issue the notes under an indenture, dated as of February 1, 1998, as supplemented, and as to be further supplemented in connection with establishing the terms of the notes (the “indenture”), between us and The Bank of New York Mellon Trust Company, N.A. (successor to JPMorgan Chase Bank, National Association), as trustee. The following description is a summary of the material provisions of the notes and the indenture. This summary is not complete and is qualified in its entirety by reference to the indenture and the notes. For a complete description of the notes, you should refer to the indenture, including the form of supplemental indenture establishing the terms of the notes, copies of which are available from us. In addition, we have filed the current indenture and will file the supplemental indenture with the SEC. Please read “Where You Can Find More Information.” For purposes of this summary, the terms “we,” “our,” “ours” and “us” refer to CenterPoint Energy Resources Corp. and not any of our subsidiaries.

We may issue additional series of debt securities from time to time under the indenture. There is no limitation on the amount of debt securities we may issue under the indenture. As of June 30, 2020, approximately $2.2 billion aggregate principal amount of debt securities were outstanding under the indenture.

We have included cross-references in the summary below to refer you to the section numbers of the indenture we are describing.

Ranking of the Notes

The notes will:

• be our general unsecured obligations;

• rank equally in right of payment with all of our other existing and future unsecured and unsubordinated indebtedness; and

• be structurally subordinated to all of the liabilities of our subsidiaries.

As of June 30, 2020, we, on an unconsolidated basis, had approximately $2.4 billion aggregate principal amount of indebtedness outstanding (inclusive of outstanding commercial paper), all of which was unsecured and unsubordinated.

Subject to exceptions, and subject to compliance with the applicable requirements, set forth in the indenture, we may discharge our obligations under the indenture with respect to the notes as described below under “— Defeasance.”

Structural Subordination

Our subsidiaries generate a significant portion of our operating income and cash flow. As a result, dividends or advances from our subsidiaries are a principal source of funds necessary to meet our debt service obligations. Contractual provisions or laws, as well as our subsidiaries’ financial condition and operating requirements, may limit our ability to obtain cash from our subsidiaries that we may require to pay our debt service obligations, including payments on the notes. The notes will be structurally subordinated to all of the liabilities of our subsidiaries with regard to the assets and earnings of our subsidiaries.

S-8

Principal, Maturity and Interest

The notes will mature on October 1, 2030. The notes are initially limited to $                in aggregate principal amount. However, we may issue additional notes of the same series from time to time, without the consent of the holders the notes. The notes will be issued in minimum denominations of $2,000 principal amount and integral multiples of $1,000 principal amount in excess thereof.

Interest on the notes will:

• accrue at the rate of                % per annum;

• be payable semi-annually in arrears on each April 1 and October 1, with the initial interest payment date being April 1, 2021;

• be payable to the person in whose name the notes are registered at the close of business on the March 15 and September 15 immediately preceding the applicable interest payment date, which we refer to with respect to the notes as “regular record dates”;

• be computed on the basis of a 360-day year comprised of twelve 30-day months; and

• be payable on overdue interest to the extent permitted by law at the same rate as interest is payable on principal.

If any interest payment date, the maturity date or any redemption date falls on a day that is not a business day, the required payment will be made on the next business day with the same force and effect as if made on the relevant interest payment date, maturity date or redemption date and no additional amounts will accrue on that payment for the period from and after the interest payment date, maturity date or redemption date, as the case may be, to the date of that payment on the next succeeding business day. Unless we default on a payment, no interest will accrue for the period from and after the applicable maturity date or redemption date.

Optional Redemption

At any time and from time to time, we may redeem at our option in whole or in part the notes on any date prior to July 1, 2030 (the “Par Call Date”), at a redemption price equal to the greater of:

• 100% of the principal amount of the notes to be redeemed; or

• the sum of the present values of the remaining scheduled payments of principal and interest on the notes to be redeemed that would be due if such notes matured on the Par Call Date but for the redemption (not including any portion of such payments of interest accrued to the date of redemption) discounted to the date of redemption on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the applicable treasury rate plus                  basis points;

plus, in each case, accrued and unpaid interest thereon, if any, to, but excluding, the redemption date.

At any time on or after the Par Call Date, we may redeem the notes, in whole or in part, at our option, by paying 100% of the principal amount of the notes to be redeemed plus accrued and unpaid interest thereon, if any, to, but excluding, the redemption date.

“treasury rate” means, with respect to any redemption date:

• the yield calculated on the third business day preceding the redemption date, as follows: for the latest day that appears in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor publication) under the caption “Treasury Constant Maturities—Nominal”, the independent investment banker shall select two yields—one for the maturity immediately before and one for the maturity

S-9

immediately after the remaining maturity of the notes to be redeemed (assuming the notes matured on the Par Call Date)—and shall interpolate on a straight-line basis using such yields; if there is no such maturity either before or after, the independent investment banker shall select the maturity closest to the Par Call Date that appears on the release; or

• if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per annum equal to the semiannual equivalent yield to maturity of the applicable comparable treasury issue, calculated by the independent investment banker using a price for the comparable treasury issue (expressed as a percentage of its principal amount) equal to the comparable treasury price for such redemption date.

The treasury rate will be calculated by the independent investment banker on the third business day preceding the date fixed for redemption.

“comparable treasury issue” means the U.S. Treasury security selected by an independent investment banker as having an actual or interpolated maturity comparable to the remaining term (remaining term) of the notes to be redeemed (assuming for this purpose that the notes matured on the Par Call Date) that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such notes.

“comparable treasury price” means (a) the average of four reference treasury dealer quotations for such redemption date, after excluding the highest and lowest reference treasury dealer quotations, or (b) if the independent investment banker obtains fewer than four such reference treasury dealer quotations, the average of all such quotations.

“independent investment banker” means one of the reference treasury dealers appointed by us.

“reference treasury dealer” means each of (a) Barclays Capital Inc., Citigroup Global Markets Inc., J.P. Morgan Securities LLC and Mizuho Securities USA LLC and each of their respective affiliates or successors, each of which is a primary U.S. government securities dealer in the United States of America (a “primary treasury dealer”), provided, however, that if any of the foregoing shall cease to be a primary treasury dealer, we will substitute therefor another primary treasury dealer and (b) any other primary treasury dealer selected by us after consultation with the independent investment banker.

“reference treasury dealer quotations” means, with respect to each reference treasury dealer and any redemption date, the average, as determined by the independent investment banker, of the bid and asked prices for the applicable comparable treasury issue (expressed in each case as a percentage of its principal amount) quoted in writing to the independent investment banker at 5:00 p.m., New York City time, on the third business day preceding such redemption date.

The trustee, at our written direction, will send a notice of redemption to each holder of notes to be redeemed by first-class mail (or in accordance with the procedures of The Depository Trust Company with respect to notes registered in the name of Cede & Co.) at least 15 and not more than 60 days prior to the date fixed for redemption. Unless we default on payment of the redemption price, interest will cease to accrue on the notes or portions thereof called for redemption on the date fixed for redemption. If fewer than all of the notes are to be redeemed, not more than 60 days prior to the redemption date, the particular notes or portions thereof called for redemption will be selected from the outstanding notes not previously called by such method as the trustee deems fair and appropriate. In the case of a partial redemption of notes registered in the name of Cede & Co., the notes to be redeemed will be determined in accordance with the procedures of The Depository Trust Company.

Sinking Fund

We are not obligated to make mandatory redemption or sinking fund payments with respect to the notes.

S-10

No Financial Covenants

The indenture does not contain financial covenants and does not restrict us from paying dividends, incurring additional indebtedness or issuing or repurchasing any of our other securities. The indenture also does not protect holders in the event of a highly leveraged transaction, except to the extent described in the accompanying prospectus under the heading “Description of Our Senior Debt Securities — Consolidation, Merger and Sale of Assets.”

Events of Default

Each of the following is an event of default under the indenture with respect to the notes:

• our failure to pay the principal of or premium, if any, on the notes when due, including at maturity or upon redemption;

• our failure to pay any interest on the notes for 30 days after the interest becomes due;

• our failure to perform, or our breach in any material respect of, any other covenant or warranty in the indenture, other than a covenant or warranty included in the indenture solely for the benefit of another series of our debt securities issued under the indenture, for 90 days after either the trustee or holders of at least 33% in principal amount of the outstanding notes have given us written notice of the breach in the manner required by the indenture;

• the default by us or any subsidiary, other than a project finance subsidiary, of ours in the payment, when due, after the expiration of any applicable grace period, of principal of indebtedness for money borrowed, other than non-recourse debt, in the aggregate principal amount then outstanding of $125 million or more, or acceleration of any indebtedness for money borrowed in such aggregate principal amount so that it becomes due and payable prior to the date on which it would otherwise have become due and payable and such acceleration is not rescinded or such default is not cured within 30 days after notice to us in accordance with the indenture; and

• specified events involving bankruptcy, insolvency or reorganization;

provided, however, that no event described in the third, fourth or fifth bullet points above will be an event of default until an officer of the trustee, assigned to and working in the trustee’s corporate trust department, has actual knowledge of the event or until the trustee receives written notice of the event at its corporate trust office, and the notice refers to the notes generally, us or the indenture. (Section 501)

If an event of default occurs and is continuing with respect to the notes, either the trustee or the holders of at least 33% in principal amount of the outstanding notes may declare the principal amount of the notes due and immediately payable. To declare the principal amount of the notes due and immediately payable, the trustee or the holders must deliver a notice that satisfies the requirements of the indenture. Upon a declaration by the trustee or the holders, we will be obligated to pay the principal amount of the notes plus accrued and unpaid interest, if any.

This right does not apply if an event of default described in the fifth bullet point above occurs. If one of the events of default described in the fifth bullet point above occurs and is continuing, the notes then outstanding under the indenture shall be due and payable immediately.

After any declaration of acceleration of the notes, but before a judgment or decree for payment, the holders of a majority in principal amount of the outstanding notes may, under certain circumstances, rescind and annul the declaration of acceleration if all events of default, other than the non-payment of principal, have been cured or waived as provided in the indenture. (Section 502) For information regarding waiver of defaults, please read “Description of Our Senior Debt Securities — Modification and Waiver” in the accompanying prospectus.

If an event of default occurs and is continuing, the trustee will generally have no obligation to exercise any of its rights or powers under the indenture at the request or direction of any of the holders, unless the holders

S-11

offer reasonable indemnity to the trustee. (Section 603) The holders of a majority in principal amount of the outstanding notes will generally have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee of the notes, provided that:

• the direction is not in conflict with any law or the indenture;

• the trustee may take any other action it deems proper which is not inconsistent with the direction; and

• the trustee will generally have the right to decline to follow the direction if an officer of the trustee determines, in good faith, that the proceeding would involve the trustee in personal liability or would otherwise be contrary to applicable law. (Section 512)

A holder of a note may only pursue a remedy under the indenture if:

• the holder has previously given the trustee written notice of a continuing event of default for the notes;

• holders of at least 33% in principal amount of the outstanding notes have made a written request to the trustee to pursue that remedy;

• the holders have offered reasonable indemnity to the trustee;

• the trustee fails to pursue that remedy within 60 days after receipt of the notice, request and offer of indemnity; and

• during that 60-day period, the holders of a majority in principal amount of the notes do not give the trustee a direction inconsistent with the request. (Section 507)

However, these limitations do not apply to a suit by a holder of a note demanding payment of the principal, premium, if any, or interest on a note on or after the date the payment is due. (Section 508)

We will be required to furnish to the trustee annually a statement by some of our officers regarding our performance or observance of any of the terms of the indenture and specifying all of our known defaults, if any. (Section 1004)

Certain Definitions

“Consolidated net tangible assets” means the total amount of our assets, including the assets of our subsidiaries, less, without duplication:

• total current liabilities (excluding indebtedness due within 12 months);

• all reserves for depreciation and other asset valuation reserves, but excluding reserves for deferred federal income taxes;

• all intangible assets such as goodwill, trademarks, trade names, patents and unamortized debt discount and expense carried as an asset; and

• all appropriate adjustments on account of minority interests of other persons holding common stock of any subsidiary, all as reflected in our most recent audited consolidated balance sheet preceding the date of such determination.

The term “control” (including the terms “controlled by” and “under common control with”) means the possession, direct or indirect, of the power to direct or cause the direction of the management and policies of a person, whether through the ownership of voting shares, by contract, or otherwise.

“Equity interests” means any capital stock, partnership, joint venture, member or limited liability or unlimited liability company interest, beneficial interest in a trust or similar entity or other equity interest or investment of whatever nature.

S-12

“Finance Lease” means a lease that, in accordance with accounting principles generally accepted in the United States of America, would be recorded as a finance lease on the balance sheet of the lessee, but excluding, for the avoidance of doubt, any operating leases or any other non-finance leases.

“Indebtedness,” as applied to us or any subsidiary, means bonds, debentures, notes and other instruments or arrangements representing obligations created or assumed by us or any such subsidiary, including any and all:

• obligations for money borrowed, other than unamortized debt discount or premium;

• obligations evidenced by a note or similar instrument given in connection with the acquisition of any business, properties or assets of any kind;

• obligations as lessee under a Finance Lease; and

• amendments, renewals, extensions, modifications and refundings of any such indebtedness or obligation listed in the three immediately preceding bullet points.

All indebtedness secured by a lien upon property owned by us or any subsidiary and upon which indebtedness we or any such subsidiary customarily pays interest, although we or any such subsidiary has not assumed or become liable for the payment of such indebtedness, is also deemed to be indebtedness of us or any such subsidiary. All indebtedness for borrowed money incurred by other persons which is directly guaranteed as to payment of principal by us or any subsidiary will for all purposes of the indenture be deemed to be indebtedness of us or any such subsidiary, but no other contingent obligation of us or any such subsidiary in respect of indebtedness incurred by other persons shall be deemed indebtedness of us or any such subsidiary.

“Lien” means any mortgage, deed of trust, pledge, hypothecation, assignment, deposit arrangement, charge, security interest, encumbrance or lien of any kind whatsoever (including any Finance Lease).

“Non-recourse debt” means (i) any indebtedness for borrowed money incurred by any project finance subsidiary to finance the acquisition, improvement, installation, design, engineering, construction, development, completion, maintenance or operation of, or otherwise to pay costs and expenses relating to or providing financing for, any project, which indebtedness for borrowed money does not provide for recourse against us or any of our subsidiaries (other than a project finance subsidiary and such recourse as exists under a performance guaranty) or any property or asset of us or any of our subsidiaries (other than equity interests in, or the property or assets of, a project finance subsidiary and such recourse as exists under a performance guaranty) and (ii) any refinancing of such indebtedness for borrowed money that does not increase the outstanding principal amount thereof (other than to pay costs incurred in connection therewith and the capitalization of any interest or fees) at the time of the refinancing or increase the property subject to any lien securing such indebtedness for borrowed money or otherwise add additional security or support for such indebtedness for borrowed money.

“Performance guaranty” means any guaranty issued in connection with any non-recourse debt that (i) if secured, is secured only by assets of or equity interests in a project finance subsidiary, and (ii) guarantees to the provider of such non-recourse debt or any other person (a) performance of the improvement, installation, design, engineering, construction, acquisition, development, completion, maintenance or operation of, or otherwise affects any such act in respect of, all or any portion of the project that is financed by such non-recourse debt, (b) completion of the minimum agreed equity or other contributions or support to the relevant project finance subsidiary, or (c) performance by a project finance subsidiary of obligations to persons other than the provider of such non-recourse debt.

“Project finance subsidiary” and “project finance subsidiaries” means any of our subsidiaries designated by us whose principal purpose is to incur non-recourse debt and/or construct, lease, own or operate the assets financed thereby, or to become a direct or indirect partner, member or other equity participant or owner in a person created for such purpose, and substantially all the assets of which subsidiary or person are limited to (x) those assets being financed (or to be financed), or the operation of which is being financed (or to be

S-13

financed), in whole or in part by non-recourse debt, or (y) equity interests in, or indebtedness or other obligations of, one or more other such subsidiaries or persons, or (z) indebtedness or other obligations of us or our subsidiaries or other persons. At the time of designation of any project finance subsidiary, the sum of the net book value of the assets of such subsidiary and the net book value of the assets of all other project finance subsidiaries then existing shall not in the aggregate exceed 10 percent of the consolidated net tangible assets.

“Subsidiary” of any entity means any corporation, partnership, joint venture, limited liability company, trust or estate of which (or in which) more than 50% of (i) the issued and outstanding capital stock having ordinary voting power to elect a majority of the board of directors of such corporation (irrespective of whether at the time capital stock of any other class or classes of such corporation shall or might have voting power upon the occurrence of any contingency), (ii) the interest in the capital or profits of such limited liability company, partnership, joint venture or other entity or (iii) the beneficial interest in such trust or estate is at the time directly or indirectly owned or controlled by such entity, by such entity and one or more of its other subsidiaries or by one or more of such entity’s other subsidiaries.

Satisfaction and Discharge

We may discharge our obligations under the indenture while the notes remain outstanding if (1) all outstanding debt securities issued under the indenture have become due and payable, (2) all outstanding debt securities issued under the indenture have or will become due and payable at their scheduled maturity within one year or (3) all outstanding debt securities issued under the indenture are scheduled for redemption in one year, and in each case, we have deposited with the trustee an amount sufficient to pay and discharge all outstanding debt securities issued under the indenture on the date of their scheduled maturity or the scheduled date of redemption and we have paid all other sums payable under the indenture. (Section 401)

Defeasance

If we deposit with the trustee funds or government securities sufficient to make payments on the notes on the dates those payments are due and payable, then, at our option, either of the following will occur:

• we will be discharged from our obligations with respect to the notes (“legal defeasance”); or

• we will no longer have any obligation to comply with the events of default in the third bullet point under “— Events of Default” above, the events of default described in the fourth bullet point under “— Events of Default” above and the restrictions described under “Description of Our Senior Debt Securities — Consolidation, Merger and Sale of Assets” in the accompanying prospectus will no longer apply to us, but some of our other obligations under the indenture and the notes, including our obligation to make payments on those notes, will survive.

If we effect legal defeasance of the notes, the holders of the notes will not be entitled to the benefits of the indenture, except for our obligations to:

• register the transfer or exchange of the notes;

• replace mutilated, destroyed, lost or stolen notes; and

• maintain paying agencies and hold moneys for payment in trust.

We will be required to deliver to the trustee an opinion of counsel that the deposit and related defeasance would not cause the holders of the notes to recognize gain or loss for federal income tax purposes and that the holders would be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if the deposit and related defeasance had not occurred. If we elect legal defeasance, that opinion of counsel must be based upon a ruling from the United States Internal Revenue Service or a change in law to that effect. (Sections 1401, 1402, 1403 and 1404)

S-14

Paying Agent and Registrar

We have designated the trustee as the sole paying agent and registrar for the notes.

Exchange and Transfer of the Notes

We will issue the notes in registered form, without coupons. The notes will be issued in minimum denominations of $2,000 principal amount and integral multiples of $1,000 principal amount in excess thereof.

Holders may present notes for exchange or for registration of transfer at the office of the security registrar or at the office of any transfer agent we designate for that purpose. The security registrar or designated transfer agent will exchange or transfer the notes if it is satisfied with the documents of title and identity of the person making the request. We will not charge a service charge for any exchange or registration of transfer of notes. However, we may require payment of a sum sufficient to cover any tax or other governmental charge payable for the exchange or registration of transfer. The trustee will serve as the security registrar. (Section 305) At any time we may:

• designate additional transfer agents;

• rescind the designation of any transfer agent; or

• approve a change in the office of any transfer agent.

However, we are required to maintain a transfer agent in each place of payment for the notes at all times. (Sections 305 and 1002)

In the event we elect to redeem the notes, neither we nor the trustee will be required to register the transfer or exchange of the notes:

• during the period beginning at the opening of business 15 days before the day we mail the notice of redemption for the notes and ending at the close of business on the day the notice is mailed; or

• if we have selected the notes for redemption, in whole or in part, except for the unredeemed portion of the notes. (Section 305)

Regarding the Trustee

The Bank of New York Mellon Trust Company, N.A., successor to JPMorgan Chase Bank, National Association, is the trustee, security registrar and paying agent under the indenture for the notes. As of June 30, 2020, the trustee served as trustee for approximately $2.2 billion aggregate principal amount of our debt securities. In addition, the trustee serves as trustee for debt securities issued by or on behalf of our affiliates, aggregating approximately $7.6 billion as of June 30, 2020. We maintain brokerage relationships with the trustee and its affiliates, each of whom may maintain other relationships with us or our affiliates in the ordinary course of business.

Book-Entry Delivery and Settlement

We will issue the notes in the form of one or more global notes in definitive, fully registered form. The global notes will be registered in the name of Cede & Co., as nominee of The Depository Trust Company, and will remain in the custody of the trustee.

Beneficial interests in the global notes will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct and indirect participants in DTC. Investors may hold interests in the global notes through DTC either directly if they are participants in DTC or indirectly through organizations that are participants in DTC. DTC has advised us as follows:

• 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 Federal Reserve

S-15

System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered under Section 17A of the Exchange Act.

• DTC holds securities that its participants deposit with DTC and facilitates the settlement among participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in participants’ accounts, thereby eliminating the need for physical movement of securities certificates.

• Direct participants include securities brokers and dealers, banks, trust companies, clearing corporations and other organizations.

• DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is owned by the users of its regulated subsidiaries.

• Access to the DTC system is also available to others such as securities brokers and dealers, banks and trust companies that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly.

The rules applicable to DTC and its direct and indirect participants are on file with the SEC.

We have provided the description of the operations and procedures of DTC in this prospectus supplement solely as a matter of convenience. These operations and procedures are solely within the control of DTC and are subject to change by it from time to time. Neither we nor the underwriters or the trustee takes any responsibility for these operations or procedures, and you are urged to contact DTC or its participants directly to discuss these matters.

We expect that under procedures established by DTC:

• upon deposit of the global notes with DTC or its custodian, DTC will credit on its internal system the accounts of direct participants designated by the underwriters with portions of the principal amounts of the global notes; and

• ownership of the notes will be shown on, and the transfer of ownership thereof will be effected only through, records maintained by DTC or its nominee, with respect to interests of direct participants, and the records of direct and indirect participants, with respect to interests of persons other than participants.

The laws of some jurisdictions may require that purchasers of securities take physical delivery of those securities in definitive form. Accordingly, the ability to transfer interests in the notes represented by a global note to those persons may be limited. In addition, because DTC can act only on behalf of its participants, who in turn act on behalf of persons who hold interests through participants, the ability of a person having an interest in notes represented by a global note to pledge or transfer those interests to persons or entities that do not participate in DTC’s system, or otherwise to take actions in respect of such interest, may be affected by the lack of a physical definitive security in respect of such interest.

So long as DTC or its nominee is the registered owner of a global note, DTC or that nominee will be considered the sole owner or holder of the notes represented by that global note for all purposes under the indenture and under the notes. Except as provided below, owners of beneficial interests in a global note will not be entitled to have notes represented by that global note registered in their names, will not receive or be entitled to receive physical delivery of certificated notes and will not be considered the owners or holders thereof under the indenture or under the notes for any purpose, including with respect to the giving of any direction, instruction or approval to the trustee. Accordingly, each holder owning a beneficial interest in a global note must rely on the procedures of DTC and, if that holder is not a direct or indirect participant, on the procedures of the participant through which that holder owns its interest, to exercise any rights of a holder of notes under the indenture or the global note.

S-16

Neither we nor the trustee will have any responsibility or liability for any aspect of the records relating to or payments made on account of notes by DTC, or for maintaining, supervising or reviewing any records of DTC relating to the notes.

Payments on the notes represented by the global notes will be made to DTC or its nominee, as the case may be, as the registered owner thereof. We expect that DTC or its nominee, upon receipt of any payment on the notes represented by a global note, will credit participants’ accounts with payments in amounts proportionate to their respective beneficial interests in the global note as shown in the records of DTC or its nominee. We also expect that payments by participants to owners of beneficial interests in the global note held through such participants will be governed by standing instructions and customary practice as is now the case with securities held for the accounts of customers registered in the names of nominees for such customers. The participants will be responsible for those payments.

Initial settlement for the notes will be made in immediately available funds. Secondary market trading between DTC participants will occur in the ordinary way in accordance with DTC rules and will be settled in immediately available funds. Although DTC has agreed to the foregoing procedures to facilitate transfers of the notes among its participants, it is under no obligation to perform or continue to perform such procedures and such procedures may be changed or discontinued at any time.

Secondary market trading between Clearstream Banking, société anonyme (“Clearstream”) participants and/or Euroclear Bank S.A./N.V., as operator of the Euroclear System (“Euroclear”) participants will occur in the ordinary way in accordance with the applicable rules and operating procedures of Clearstream and Euroclear, as applicable.

Cross-market transfers between participants in DTC, on the one hand, and participants in Euroclear or Clearstream, on the other hand, will be effected through DTC in accordance with the DTC’s rules on behalf of Euroclear or Clearstream, as the case may be, by their respective U.S. depositaries; however, such cross-market transactions will require delivery of instructions to Euroclear or Clearstream, as the case may be, by the counterparty in such system in accordance with the rules and procedures and within the established deadlines (European time) of such system. Euroclear or Clearstream, as the case may be, will, if the transaction meets its settlement requirements, deliver instructions to its U.S. depositary to take action to effect final settlement on its behalf by delivering or receiving interests in the global securities through DTC, and making or receiving payment in accordance with normal procedures for same-day fund settlement. Participants in Euroclear or Clearstream may not deliver instructions directly to their respective U.S. depositaries.

Due to time zone differences, the securities accounts of a participant in Euroclear or Clearstream purchasing an interest in a global security from a direct participant in DTC will be credited, and any such crediting will be reported to the relevant participant in Euroclear or Clearstream, during the securities settlement processing day (which must be a business day for Euroclear or Clearstream) immediately following the settlement date of DTC. Cash received in Euroclear or Clearstream as a result of sales of interests in a global security by or through a participant in Euroclear or Clearstream to a direct participant in DTC will be received with value on the settlement date of DTC but will be available in the relevant Euroclear or Clearstream cash account only as of the business day for Euroclear or Clearstream following DTC’s settlement date.

Certificated Notes

Certificated notes will be issued to each person that DTC identifies as the beneficial owner of the notes represented by the global notes, upon surrender by DTC of the global notes, if (i) DTC or any successor depositary (the “depositary”) notifies us that it is no longer willing or able to act as a depositary for the global notes or DTC ceases to be registered as a clearing agency under the Exchange Act, and a successor depositary is not appointed within 90 days of such notice or cessation, (ii) we, at our option and subject to DTC procedures, notify the trustee in writing that we elect to cause the issuance of notes in definitive form under the indenture or (iii) upon the occurrence of certain other events as provided pursuant to the indenture.

S-17

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

The following discussion is a summary of the material U.S. federal income tax consequences relevant to the acquisition, ownership and disposition of the notes issued pursuant to this offering. This discussion is based upon the provisions of the Internal Revenue Code of 1986, as amended (the “Code”), applicable U.S. Treasury regulations promulgated thereunder, judicial authority and administrative interpretations, all as of the date of this offering, and all of which are subject to change, possibly with retroactive effect, or are subject to different interpretations. We cannot assure you that the Internal Revenue Service (the “IRS”) will not challenge one or more of the tax consequences described in this discussion, and we have not obtained, nor do we intend to obtain, a ruling from the IRS or an opinion of counsel with respect to the U.S. federal income tax consequences of acquiring, owning or disposing of the notes.

This discussion is limited to holders who purchase the notes in this offering for cash at a price equal to the issue price of the notes (i.e., the first price at which a substantial amount of the notes is sold for cash other than to bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers) and who hold the notes as capital assets (generally, property held for investment). This discussion does not address any U.S. federal tax considerations other than U.S. federal income tax considerations (such as estate and gift tax considerations), or the tax considerations arising under the laws of any foreign, state, local or other jurisdiction or any income tax treaty. In addition, this discussion does not address all tax considerations that may be important to a particular holder in light of the holder’s circumstances, or to certain categories of investors that may be subject to special rules, such as:

• brokers or dealers in securities or currencies;

• traders in securities that have elected the mark-to-market method of accounting for their securities;

• U.S. holders (as defined below) whose functional currency is not the U.S. dollar;

• persons holding notes as part of a hedge, straddle, conversion or other “synthetic security” or integrated transaction;

• former U.S. citizens or long-term residents of the United States;

• banks or other financial institutions;

• insurance companies;

• regulated investment companies;

• real estate investment trusts;

• persons subject to the alternative minimum tax;

• entities that are tax-exempt for U.S. federal income tax purposes;

• U.S. holders required to accelerate the recognition of any item of gross income with respect to the notes as a result of such income being recognized on an “applicable financial statement” (within the meaning of Section 451(b) of the Code); and

• partnerships, S corporations and other pass-through entities or arrangements and holders of interests therein.

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds notes, the U.S. federal income tax treatment of a partner of the partnership generally will depend upon the status of the partner and the activities of the partnership and upon certain determinations made at the partner level. If you are a partner of a partnership considering an investment in the notes, you are urged to consult your own tax advisor about the U.S. federal income tax consequences of acquiring, owning and disposing of the notes.

S-18

INVESTORS CONSIDERING THE PURCHASE OF NOTES ARE URGED TO CONSULT THEIR OWN TAX ADVISORS REGARDING THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES OF THE ACQUISITION, OWNERSHIP AND DISPOSITION OF THE NOTES UNDER OTHER U.S. FEDERAL TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL OR FOREIGN JURISDICTION OR UNDER ANY APPLICABLE TAX TREATY.

Certain Additional Payments

In certain circumstances (see “Description of the Notes — Optional Redemption”), we may be obligated to pay amounts with respect to the notes that are in excess of stated interest on or principal of the notes and/or pay amounts in redemption of the notes prior to their stated maturity. We intend to take the position that the likelihood that we will be required to make such payments is remote as of the issue date of the notes and therefore that these provisions do not cause the notes to be treated as “contingent payment debt instruments” within the meaning of the applicable Treasury Regulations. However, additional income will be recognized to a holder of notes if any such additional payment is made. Our position that the contingencies described above are remote is binding on a holder, unless the holder discloses in the proper manner to the IRS that it is taking a different position. If the IRS successfully challenged our position, then the notes could be treated as contingent payment debt instruments, in which case holders could be required to accrue interest income at a rate higher than the stated interest rate on the notes and to treat as ordinary income, rather than capital gain, any gain recognized on a sale, exchange, retirement or redemption of a note. The remainder of this discussion assumes that the notes will not be treated as contingent payment debt instruments. You should consult your own tax advisor regarding the possible application of the contingent payment debt instrument rules to the notes.

Tax Consequences to U.S. Holders

The following summary will apply to you if you are a U.S. holder of the notes. You are a “U.S. holder” for purposes of this discussion if you are a beneficial owner of a note and you are for U.S. federal income tax purposes:

• an individual who is a U.S. citizen or U.S. resident alien;

• a corporation, or other entity taxable as a corporation for U.S. federal income tax purposes, that was created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

• an estate the income of which is subject to U.S. federal income taxation regardless of its source; or

• a trust (i) the administration of which is subject to the primary supervision of a U.S. court and that has one or more United States persons that have the authority to control all substantial decisions of the trust or (ii) that has made a valid election under applicable U.S. Treasury regulations to be treated as a United States person.

Interest on the Notes

Interest on the notes generally will be taxable to you as ordinary income at the time it is received or accrued in accordance with your regular method of tax accounting for U.S. federal income tax purposes.

Disposition of the Notes

You will generally recognize capital gain or loss on the sale, redemption, exchange, retirement or other taxable disposition of a note equal to the difference, if any, between the proceeds you receive (excluding any proceeds attributable to accrued but unpaid interest, which will be taxable as ordinary interest income to the extent you have not previously included such amounts in income) and your adjusted tax basis in the note. The

S-19

proceeds you receive will include the amount of any cash and the fair market value of any other property received for the note. Your adjusted tax basis in the note will generally equal the amount you paid for the note. Any gain or loss will be long-term capital gain or loss if you held the note for more than one year at the time of the sale, redemption, exchange, retirement or other taxable disposition. Long-term capital gains of individuals, estates and trusts currently are eligible for reduced rates of U.S. federal income tax. The deductibility of capital losses is subject to limitations.

Information Reporting and Backup Withholding

Information reporting generally will apply to payments of interest on, and the proceeds of the sale or other disposition (including a redemption, exchange or retirement) of, notes held by you, and backup withholding will apply to such payments unless you provide to the applicable withholding agent your taxpayer identification number, certified under penalties of perjury, as well as certain other information or otherwise establish an exemption from backup withholding. Backup withholding is not an additional tax. Any amount withheld under the backup withholding rules is allowable as a credit against your U.S. federal income tax liability, if any, and a refund may be obtained from the IRS if the amounts withheld exceed your actual U.S. federal income tax liability and you timely provide the required information or appropriate claim form to the IRS.

Additional Tax on Net Investment Income

An additional 3.8% tax is imposed on the “net investment income” of certain United States citizens and resident aliens, and on the undistributed “net investment income” of certain estates and trusts. Among other items, “net investment income” generally includes gross income from interest and net gain from the disposition of property, such as the notes, less certain deductions. You are encouraged to consult your tax advisor with respect to this additional tax and its applicability in your particular circumstances.

Tax Consequences to Non-U.S. Holders

The following summary will apply to you if you are a non-U.S. holder of notes. You are a “non-U.S. holder” for purposes of this discussion if you are a beneficial owner of notes that is, for U.S. federal income tax purposes, an individual, corporation, estate or trust that is not a U.S. holder.

Interest on the Notes

Subject to the discussion below of backup withholding and FATCA (as defined below) withholding, payments to you of interest on the notes generally will not be subject to U.S. federal income tax and will be exempt from withholding of U.S. federal income tax under the “portfolio interest” exemption if you properly certify as to your foreign status, as described below, and:

• you do not own, actually or constructively, 10% or more of the total combined voting power of all classes of our stock entitled to vote;

• you are not a “controlled foreign corporation” that is related to us (actually or constructively);

• you are not a bank whose receipt of interest on the notes is in connection with an extension of credit made pursuant to a loan agreement entered into in the ordinary course of your trade or business; and

• interest on the notes is not effectively connected with your conduct of a U.S. trade or business.

The portfolio interest exemption generally applies only if you also appropriately certify as to your foreign status. You can generally meet the certification requirement by providing a properly executed IRS Form W-8BEN or IRS Form W-8BEN-E (or other applicable or successor form) to the applicable withholding agent. If you hold the notes through a financial institution or other agent acting on your behalf, you may be required to provide appropriate certifications to the agent. Your agent will then generally be required to provide appropriate

S-20

certifications to the applicable withholding agent, either directly or through other intermediaries. Special rules apply to foreign partnerships, estates and trusts, and in certain circumstances certifications as to the foreign status of partners, trust owners or beneficiaries may have to be provided to the applicable withholding agent. In addition, special rules apply to qualified intermediaries that enter into withholding agreements with the IRS.

If you cannot satisfy the requirements described above, payments of interest made to you will be subject to U.S. federal withholding tax at a 30% rate, unless (i) you provide the applicable withholding agent with a properly executed IRS Form W-8BEN or IRS Form W-8BEN-E (or other applicable or successor form) claiming an exemption from (or a reduction of) withholding under an income tax treaty, or (ii) the payments of such interest are effectively connected with your conduct of a trade or business in the United States (and, if required by an applicable income tax treaty, are attributable to a permanent establishment maintained by you in the United States) and you meet the certification requirements described below. (See “— Income or Gain Effectively Connected with a U.S. Trade or Business.”)

The certifications described above and below must be provided to the applicable withholding agent prior to the payment of interest and must be updated periodically. If you do not timely provide the applicable withholding agent with the required certification, but you qualify for a reduced rate under an applicable income tax treaty, you may obtain a refund of any excess amounts withheld if you timely provide the required information or appropriate claim form to the IRS.

Disposition of the Notes

Subject to the discussion of backup withholding below, you generally will not be subject to U.S. federal income tax on any gain (excluding any amount attributable to accrued and unpaid interest, which generally will be treated as interest and may be subject to the rules discussed above in “— Interest on the Notes”) realized on the sale, redemption, exchange, retirement or other taxable disposition of a note unless:

• the gain is effectively connected with the conduct by you of a U.S. trade or business (and, if required by an applicable income tax treaty, you maintain a permanent establishment in the United States to which such gain is attributable); or

• you are a non-resident alien individual who has been present in the United States for 183 days or more in the taxable year of disposition and certain other requirements are met.

If your gain is described in the first bullet point above, you generally will be subject to U.S. federal income tax in the manner described under “— Income or Gain Effectively Connected with a U.S. Trade or Business.” If you are a non-U.S. holder described in the second bullet point above, you will be subject to a flat 30% (or lower applicable income tax treaty rate) U.S. federal income tax on the gain derived from the sale or other disposition, which may be offset by certain U.S. source capital losses.

Income or Gain Effectively Connected with a U.S. Trade or Business

If any interest on the notes or gain from the sale, redemption, exchange, retirement or other taxable disposition of the notes is effectively connected with a U.S. trade or business conducted by you (and, if required by an applicable income tax treaty, you maintain a permanent establishment in the United States to which such interest or gain is attributable), then the interest income or gain will be subject to U.S. federal income tax at regular graduated income tax rates generally in the same manner as if you were a U.S. holder. Effectively connected interest income will not be subject to U.S. federal withholding tax if you satisfy certain certification requirements by providing to the applicable withholding agent a properly executed IRS Form W-8ECI (or successor form). In addition, if you are a corporation, that portion of your earnings and profits that is effectively connected with your U.S. trade or business may also be subject to a “branch profits tax” at a 30% rate, unless an applicable income tax treaty provides for a lower rate. For this purpose, interest received on a note and gain recognized on the disposition of a note will be included in earnings and profits if the interest or gain is effectively connected with the conduct by you of a U.S. trade or business.

S-21

Information Reporting and Backup Withholding

Payments to you of interest on a note, and amounts withheld from such payments, if any, generally will be required to be reported to the IRS and to you. Copies of the information returns reporting such interest payments and withholding may also be made available to the tax authorities of the country in which you reside or are established under the provisions of a specific treaty or agreement.

Backup withholding generally will not apply to payments to you of interest on a note if the certification described in “— Tax Consequences to Non-U.S. Holders — Interest on the Notes” is duly provided or you otherwise establish an exemption.

Proceeds from the disposition of a note effected by the U.S. office of a U.S. or foreign broker will be subject to information reporting requirements and backup withholding unless you properly certify under penalties of perjury as to your foreign status on IRS Form W-8BEN or IRS Form W-8BEN-E (or other applicable or successor form) and certain other conditions are met or you otherwise establish an exemption. Information reporting requirements and backup withholding generally will not apply to any proceeds from the disposition of a note effected outside the United States by a foreign office of a broker. However, unless such a broker has documentary evidence in its records that you are not a United States person and certain other conditions are met, or you otherwise establish an exemption, information reporting will apply to a payment of the proceeds of the disposition of a note effected outside the United States by such a broker if it has certain relationships with the United States.

Backup withholding is not an additional tax. Any amount withheld under the backup withholding rules is allowable as a credit against your U.S. federal income tax liability, if any, and a refund may be obtained from the IRS if the amounts withheld exceed your actual U.S. federal income tax liability and you timely provide the required information or appropriate claim form to the IRS.

Withholding on Payments to Certain Foreign Entities

Sections 1471 through 1474 of the Code and the U.S. Treasury regulations and administrative guidance issued thereunder (referred to as “FATCA”) impose a 30% U.S. federal withholding tax on “withholdable payments” (as defined in the Code), including payments of interest on the notes if paid to a “foreign financial institution” or a “non-financial foreign entity” (each as defined in the Code) (including, in some cases, when such foreign financial institution or non-financial foreign entity is acting as an intermediary), unless: (i) in the case of a foreign financial institution, such institution enters into an agreement with the U.S. government to withhold on certain payments, and to collect and provide to the U.S. tax authorities substantial information regarding U.S. account holders of such institution (which includes certain equity and debt holders of such institution, as well as certain account holders that are foreign entities with U.S. owners); (ii) in the case of a non-financial foreign entity, such entity certifies that it does not have any “substantial United States owners” (as defined in the Code) or provides the withholding agent with a certification identifying its direct and indirect substantial United States owners (generally by providing an IRS Form W-8BEN-E); or (iii) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules and provides appropriate documentation (such as an IRS Form W-8BEN-E). While withholdable payments would have originally included payments of gross proceeds from the sale or other disposition of a note on or after January 1, 2019, proposed U.S. Treasury Regulations provide that such payments of gross proceeds (other than amounts treated as interest) do not constitute withholdable payments. Taxpayers may rely generally on these proposed U.S. Treasury Regulations until they are revoked or final U.S. Treasury Regulations are issued.

Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States with respect to these rules may be subject to different rules. Under certain circumstances, a beneficial owner of notes might be eligible for refunds or credits of such taxes. You are urged to consult your tax advisor regarding the effects of FATCA on your investment in the notes.

UNDERWRITING

Subject to the terms and conditions set forth in an underwriting agreement between us and the underwriters named below for the notes, for whom Barclays Capital Inc., Citigroup Global Markets Inc., J.P. Morgan Securities LLC and Mizuho Securities USA LLC are acting as representatives, we have agreed to sell to each of the underwriters, and each of the underwriters has severally agreed to purchase from us, the principal amount of notes set forth opposite its name below.

Underwriter	Principal Amount of Notes
Barclays Capital Inc.	$
Citigroup Global Markets Inc.
J.P. Morgan Securities LLC
Mizuho Securities USA LLC
TD Securities (USA) LLC
U.S. Bancorp Investments, Inc.
Siebert Williams Shank & Co., LLC
Total	$

The underwriters are offering the notes, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by counsel, including the validity of the notes, and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of officer’s 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.

The underwriters have advised us that they propose to initially offer the notes to the public at the offering price appearing on the cover page of this prospectus supplement and may also offer the notes to dealers at a price that represents a concession not in excess of                % of the principal amount of the notes. Any underwriter may allow, and any of these dealers may re-allow, a concession not in excess of                 % of the principal amount of the notes. After the initial offering of the notes, the underwriters may from time to time vary the offering pricing and other selling terms.

The obligations of the underwriters, including their agreement to purchase the notes from us, are several and not joint. The underwriting agreement provides that the obligations of the underwriters are subject to certain conditions and that the underwriters will be obligated to purchase all of the notes if any are purchased. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of the non-defaulting underwriters under the agreement may be increased or the offering of notes may be terminated.

The notes will be a new issue of securities for which currently there is no established trading market. We do not intend to apply for listing of the notes on any securities exchange or for quotation of the notes on any dealer quotation system. The underwriters have advised us that they intend to make a market in the notes after the offering, although they are under no obligation to do so. The underwriters may discontinue any market-making activities at any time without any notice. We can give no assurance as to the liquidity of the trading market for the notes or that a public trading market for such notes will develop.

We expect that delivery of the notes offered hereby will be made against payment therefor on or about October                , 2020, which will be the                business day following the date of pricing of the notes (this settlement cycle being referred to as “T+                ”). Under Rule 15c6-1 of the Exchange Act, trades in the secondary market generally are required to settle in two business days, unless the parties to a trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes on the initial pricing date of the notes or

S-24

the next                succeeding business days will be required, by virtue of the fact that the notes initially will settle in T+                , to specify alternative settlement arrangements at the time of any such trade to prevent a failed settlement and should consult their own advisors.

In connection with the offering of the notes, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the notes. Specifically, the underwriters may overallot in connection with the offering of the notes, creating a syndicate short position. In addition, the underwriters may bid for, and purchase, the notes in the open market to cover short positions or to stabilize the price of the notes. Finally, the underwriters may reclaim selling concessions allowed for distributing the notes in the offering, if the underwriters repurchase previously distributed notes in transactions to cover short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market prices of the notes above independent market levels. The underwriters are not required to engage in any of these activities, and may end any of them at any time without notice.

The underwriters may also impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount recovered by it because the representatives have repurchased notes sold by or for the account of such underwriter in stabilizing or short covering transactions.

We estimate that our share of the total expenses of the offering, excluding the underwriting discount will be approximately $1.2 million.

We have agreed to indemnify the several underwriters against, or contribute to payments that the underwriters may be required to make in respect of, certain liabilities, including liabilities under the Securities Act of 1933, as amended.

The underwriters and their affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities. In the ordinary course of their respective businesses, certain of the underwriters and/or their affiliates have engaged, and may in the future engage, in commercial banking, investment banking, trust or investment management transactions with us and our affiliates for which they have received, and will in the future receive, customary compensation.

In addition, in the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers, and such investment and securities activities may involve securities and instruments of ours or our affiliates. If any of the underwriters and their affiliates has a lending relationship with us, certain of these underwriters or their affiliates routinely hedge and certain of these 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 notes offered hereby. Any credit default swaps or short positions could adversely affect future trading prices of the notes offered hereby. The underwriters and their respective affiliates may also make investment recommendations or publish or express independent research views in respect of such securities or financial instruments and may at any time hold, or recommend to clients that they acquire, long or short positions in such securities and instruments.

Conflicts of Interest

One of the underwriters owns some of our commercial paper and as a result could receive greater than 5% of the net proceeds from this offering in connection with any such repayment, and would therefore be deemed to have a conflict of interest under Financial Industry Regulatory Authority (“FINRA”) Rule 5121.

S-25

Consequently, this offering of notes must be conducted in compliance with the provisions of FINRA Rule 5121 and such underwriter or its affiliates will not be permitted to sell notes in this offering to accounts over which they exercise discretionary authority without the prior specific written approval of the account holders.

Consequently no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the EEA or in the UK has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA or in the UK may be unlawful under the PRIIPs Regulation.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING INFORMATION

In this prospectus supplement, including the information we incorporate by reference, we make statements concerning our expectations, beliefs, plans, objectives, goals, strategies, future events or performance and underlying assumptions and other statements that are not historical facts. These statements are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Actual results may differ materially from those expressed or implied by these statements. You can generally identify our forward-looking statements by the words “anticipate,” “believe,” “continue,” “could,” “estimate,” “estimated,” “expect,” “forecast,” “goal,” “intend,” “may,” “objective,” “plan,” “potential,” “predict,” “projection,” “should,” “target,” “will” or other similar words.

We have based our forward-looking statements on our management’s beliefs and assumptions based on information reasonably available to our management at the time the statements are made. We caution you that assumptions, beliefs, expectations, intentions and projections about future events may and often do vary materially from actual results. Therefore, we cannot assure you that actual results will not differ materially from those expressed or implied by our forward-looking statements.

The following are some of the factors that could cause actual results to differ from those expressed or implied by our forward-looking statements:

• the expected benefits of the merger transaction whereby CenterPoint Energy formed a wholly-owned subsidiary and that subsidiary merged with and into Vectren Corporation (“Vectren”), with Vectren continuing as the surviving corporation and as a wholly-owned subsidiary of CenterPoint Energy, which closed on February 1, 2019 (“Merger”), and integration, including the outcome of shareholder litigation filed against Vectren that could reduce anticipated benefits of the Merger, as well as the ability to successfully integrate the Vectren businesses and to realize anticipated benefits and commercial opportunities;

• the recording of impairment charges;

• industrial, commercial and residential growth in our service territories and changes in market demand, including the demand for our non-utility products and services and effects of energy efficiency measures and demographic patterns;

• timely and appropriate rate actions that allow recovery of costs and a reasonable return on investment;

• future economic conditions in regional and national markets and their effect on sales, prices and costs;

• weather variations and other natural phenomena, including the impact of severe weather events on operations and capital;

• the COVID-19 pandemic and its effect on our operations, business and financial condition, our industries and the communities we serve, U.S. and world financial markets and supply chains, potential regulatory actions and changes in customer and stakeholder behaviors relating thereto;

• volatility and a substantial recent decline in the markets for oil and natural gas as a result of the actions of crude-oil exporting nations and the Organization of Petroleum Exporting Countries and reduced worldwide consumption due to the COVID-19 pandemic;

• state and federal legislative and regulatory actions or developments affecting various aspects of our businesses, including, among others, energy deregulation or re-regulation, pipeline integrity and safety and changes in regulation and legislation pertaining to trade, health care, finance and actions regarding the rates charged by our regulated businesses;

• tax legislation, including the effects of the Coronavirus Aid, Relief, and Economic Security Act and of the tax reform legislation informally called the Tax Cuts and Jobs Act of 2017 (which includes but is

S-31

not limited to any potential changes to tax rates, tax credits and/or interest deductibility) and uncertainties involving state commissions’ and local municipalities’ regulatory requirements and determinations regarding the treatment of excess deferred income taxes and our rates;

• our ability to mitigate weather impacts through normalization or rate mechanisms, and the effectiveness of such mechanisms;

• actions by credit rating agencies, including any potential downgrades to credit ratings;

• problems with regulatory approval, legislative actions, construction, implementation of necessary technology or other issues with respect to major capital projects that result in delays or cancellation or in cost overruns that cannot be recouped in rates;

• the availability and prices of raw materials and services and changes in labor for current and future construction projects and operations and maintenance costs, including our ability to control such costs;

• local, state and federal legislative and regulatory actions or developments relating to the environment, including, among others, those related to global climate change, air emissions and carbon discharges;

• the impact of unplanned facility outages or other closures;

DESCRIPTION OF OUR SENIOR DEBT SECURITIES

The debt securities offered by this prospectus will be issued under an indenture, dated as of February 1, 1998, as supplemented, between us and The Bank of New York Mellon Trust Company, National Association (successor to JPMorgan Chase Bank, National Association), as trustee. We have incorporated by reference the indenture as an exhibit to the registration statement of which this prospectus is a part. We have summarized selected provisions of the indenture and the debt securities below. This summary is not complete and is qualified in its entirety by reference to the indenture. References to section numbers in this prospectus, unless otherwise indicated, are references to section numbers of the indenture. For purposes of this summary, the terms “we,” “our,” “ours,” and “us” refer only to CenterPoint Energy Resources Corp. and not to any of our subsidiaries.

We may issue debt securities from time to time in one or more series under the indenture. There is no limitation on the amount of debt securities we may issue under the indenture. We will describe the particular terms of each series of debt securities we offer in a supplement to this prospectus. The terms of our debt securities will include those set forth in the indenture and those made a part of the indenture by the Trust Indenture Act of 1939.

Terms

We may issue debt securities in separate series from time to time under the indenture. The total principal amount of debt securities that may be issued under the indenture is unlimited. We may limit the maximum total principal amount for the debt securities of any series. However, any limit may be increased by resolution of our board of directors. (Section 301) We will establish the terms of each series of debt securities, which may not be inconsistent with the indenture, in a supplemental indenture.

We will describe the specific terms of the series of debt securities being offered in a supplement to this prospectus. These terms will include some or all of the following:

• any limit on the total principal amount of the debt securities of the series,

• the date or dates on which the principal of the debt securities will be payable or the method used to determine or extend those dates,

If there are any special United States federal income tax considerations applicable to debt securities we sell at an original issue discount, we will describe them in the prospectus supplement. In addition, we will describe in the prospectus supplement any special United States federal income tax considerations and any other special considerations for any debt securities we sell which are denominated in a currency or currency unit other than U.S. dollars.

11

Form, Exchange and Transfer

We will issue the debt securities in registered form, without coupons. Unless we inform you otherwise in the prospectus supplement, we will only issue debt securities in denominations of integral multiples of $1,000. (Section 302)

Holders generally will be able to exchange debt securities for other debt securities of the same series with the same total principal amount and the same terms but in different authorized denominations. (Section 305)

Holders may present debt securities for exchange or for registration of transfer at the office of the security registrar or at the office of any transfer agent we designate for that purpose. The security registrar or designated transfer agent will exchange or transfer the debt securities if it is satisfied with the documents of title and identity of the person making the request. We will not charge a service charge for any exchange or registration of transfer of debt securities. However, we may require payment of a sum sufficient to cover any tax or other governmental charge payable for the registration of transfer or exchange. Unless we inform you otherwise in the prospectus supplement, we will appoint the trustee as security registrar. We will identify any transfer agent in addition to the security registrar in the prospectus supplement. (Section 305) At any time we may:

• designate additional transfer agents,

• rescind the designation of any transfer agent, or

• approve a change in the office of any transfer agent.

However, we are required to maintain a transfer agent in each place of payment for the debt securities at all times. (Sections 305 and 1002)

If we elect to redeem a series of debt securities, neither we nor the trustee will be required:

• to issue, register the transfer of or exchange any debt securities of that series during the period beginning at the opening of business 15 days before the day we mail the notice of redemption for the series and ending at the close of business on the day the notice is mailed, or

• to register the transfer or exchange of any debt security of that series if we have so selected the series for redemption, in whole or in part, except for the unredeemed portion of the series. (Section 305)

Book-Entry

We may issue the debt securities of a series in the form of one or more global debt securities that would be deposited with a depositary or its nominee identified in the prospectus supplement. We may issue global debt securities in either temporary or permanent form. We will describe in the prospectus supplement the terms of any depositary arrangement and the rights and limitations of owners of beneficial interests in any global debt security.

Payment and Paying Agents

Under the indenture, we will pay interest on the debt securities to the persons in whose names the debt securities are registered at the close of business on the regular record date for each interest payment. However, unless we inform you otherwise in the prospectus supplement, we will pay the interest payable on the debt securities at their stated maturity to the persons to whom we pay the principal amount of the debt securities. The initial payment of interest on any series of debt securities issued between a regular record date and the related interest payment date will be payable in the manner provided by the terms of the series, which we will describe in the prospectus supplement. (Section 307)

12

Unless we inform you otherwise in the prospectus supplement, we will pay principal, premium, if any, and interest on the debt securities at the offices of the paying agents we designate. However, except in the case of a global security, we may pay interest by:

• check mailed to the address of the person entitled to the payment as it appears in the security register, or

• by wire transfer in immediately available funds to the place and account designated in writing by the person entitled to the payment as specified in the security register.

We will designate the trustee as the sole paying agent for the debt securities unless we inform you otherwise in the prospectus supplement. If we initially designate any other paying agents for a series of debt securities, we will identify them in the prospectus supplement. At any time, we may designate additional paying agents or rescind the designation of any paying agents. However, we are required to maintain a paying agent in each place of payment for the debt securities at all times. (Sections 307 and 1002)

Any money deposited with the trustee or any paying agent for the payment of principal, premium, if any, and interest on the debt securities that remains unclaimed for two years after the date the payments became due, may be repaid to us upon our request. After we have been repaid, holders entitled to those payments may only look to us for payment as our unsecured general creditors. The trustee and any paying agents will not be liable for those payments after we have been repaid. (Section 1003)

Restrictive Covenants

We will describe any restrictive covenants for any series of debt securities in the prospectus supplement.

Consolidation, Merger and Sale of Assets

Under the indenture, we may not consolidate with or merge into, or convey, transfer or lease our properties and assets substantially as an entirety, to any person, referred to as a “successor person,” and we may not permit any person to consolidate with or merge into, or convey, transfer or lease its properties and assets substantially as an entirety to us, unless:

• the successor person is a corporation, partnership, trust or other entity organized and validly existing under the laws of the United States of America or any state thereof or the District of Columbia,

• the successor person expressly assumes our obligations with respect to the debt securities and the indenture,

• immediately after giving effect to the transaction, no event of default, and no event which, after notice or lapse of time or both, would become an event of default, would occur and be continuing, and

• we have delivered to the trustee the certificates and opinions required under the indenture. (Section 801)

As used in the indenture, the term “corporation” means a corporation, association, company, joint-stock company or business trust.

Events of Default

Unless we inform you otherwise in the prospectus supplement, each of the following will be an event of default under the indenture for a series of debt securities:

• our failure to pay principal or premium, if any, on that series when due, including at maturity or upon redemption,

• our failure to pay any interest on that series for 30 days after the interest becomes due,

• our failure to deposit any sinking fund payment relating to that series when due,

13

• our failure to perform, or our breach in any material respect of, any other covenant or warranty in the indenture, other than a covenant or warranty included in the indenture solely for the benefit of another series of debt securities issued under the indenture, for 90 days after either the trustee or holders of at least 25% in principal amount of the outstanding debt securities of that series have given us written notice of the breach in the manner required by the indenture,

• specified events involving our bankruptcy, insolvency or reorganization, and

• any other event of default we may provide for that series,

provided, however, that no event described in the fourth, fifth or sixth bullet points above will be an event of default until an officer of the trustee, assigned to and working in the trustee’s corporate trust department, has actual knowledge of the event or until the trustee receives written notice of the event at its corporate trust office, and the notice refers to the debt securities generally, us or the indenture. (Section 501)

If an event of default for a series of debt securities occurs and is continuing, either the trustee or the holders of at least 25% in principal amount of the outstanding debt securities of that series may declare the principal amount of all the debt securities of that series due and immediately payable. To declare the principal amount of that series of debt securities due and immediately payable, the trustee or the holders must deliver a notice that satisfies the requirements of the indenture. Upon a declaration by the trustee or the holders, we will be obligated to pay the principal amount of the series of debt securities.

The right described in the preceding paragraph does not apply if:

• an event of default described in the fifth bullet point above occurs, or

• an event of default described in the fourth or sixth bullet points above that applies to all outstanding debt securities occurs.

If any of these events of default occurs and is continuing, either the trustee or holders of at least 25% in principal amount of all of the debt securities then outstanding, treated as one class, may declare the principal amount of all of the debt securities then outstanding to be due and payable immediately. To declare the principal amount of the debt securities due and immediately payable, the trustee or the holders must deliver a notice that satisfies the requirements of the indenture. Upon a declaration by the trustee or the holders, we will be obligated to pay the principal amount of the debt securities.

However, after any declaration of acceleration of a series of debt securities, but before a judgment or decree for payment has been obtained, the holders of a majority in principal amount of the outstanding debt securities of that series may rescind and annul the declaration of acceleration if:

• we have paid or deposited with the trustee a sum sufficient to pay:

• all overdue interest,

• the principal and premium, if any, due otherwise than by the declaration of acceleration and any interest on such amounts,

• any interest on overdue interest, to the extent legally permitted, and

• all amounts paid or advanced by, or due to the trustee under the indenture, and

• all events of default with respect to that series of debt securities, other than the nonpayment of the principal which became due solely by virtue of the declaration of acceleration, have been cured or waived. (Section 502)

If an event of default occurs and is continuing, the trustee will generally have no obligation to exercise any of its rights or powers under the indenture at the request or direction of any of the holders, unless the holders

14

offer reasonable indemnity to the trustee. (Section 603) The holders of a majority in principal amount of the outstanding debt securities of any series will generally have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee for the debt securities of that series, provided that:

• the direction is not in conflict with any law or the indenture,

• the trustee may take any other action it deems proper which is not inconsistent with the direction, and

• the trustee will generally have the right to decline to follow the direction if an officer of the trustee determines, in good faith, that the proceeding would involve the trustee in personal liability or would otherwise be contrary to applicable law. (Section 512)

A holder of a debt security of any series may only pursue a remedy under the indenture if:

• the holder gives the trustee written notice of a continuing event of default for that series,

• holders of at least 25% in principal amount of the outstanding debt securities of that series make a written request to the trustee to institute proceedings with respect to the event of default,

• the holders offer reasonable indemnity to the trustee,

• the trustee fails to pursue that remedy within 60 days after receipt of the notice, request and offer of indemnity, and

• during that 60-day period, the holders of a majority in principal amount of the debt securities of that series do not give the trustee a direction inconsistent with the request. (Section 507)

No holder has any right in any manner by virtue of, or availing itself of, any provision of the indenture to affect, disturb or prejudice the rights of any other holder of debt securities, or to obtain or seek to obtain priority or preference over any other holder, or to enforce any right under the indenture, except in the manner provided for in the indenture and for the equal and ratable benefit of all holders of debt securities. (Section 507)

However, these limitations do not apply to a suit by a holder of a debt security demanding payment of the principal, premium, if any, or interest on a debt security on or after the date the payment is due. (Section 508)

We will be required to furnish to the trustee annually a statement by some of our officers regarding our performance or observance of any of the terms of the indenture and specifying all of our known defaults, if any. (Section 1004)

Modification and Waiver

We may enter into one or more supplemental indentures with the trustee without the consent of the holders of the debt securities to:

• evidence the succession of another corporation to us, or successive successions and the assumption of our covenants, agreements and obligations by a successor,

• add to our covenants for the benefit of the holders of any series of debt securities or to surrender any of our rights or powers,

• add events of default for any series of debt securities,

• add to or change any provisions of the indenture to the extent necessary to issue debt securities in bearer form,

• add to, change or eliminate any provision of the indenture applying to one or more series of debt securities, provided that if such action adversely affects the interests of any holder of any series of debt securities, the addition, change or elimination will become effective with respect to that series only when no security of that series remains outstanding,

15

• convey, transfer, assign, mortgage or pledge any property to or with the trustee or surrender any right or power conferred upon us by the indenture,

• establish the form or terms of any series of debt securities,

• provide for uncertificated securities in addition to certificated securities,

• evidence and provide for successor trustees or add or change any provisions to the extent necessary to appoint a separate trustee or trustees for a specific series of debt securities,

• correct any ambiguity, defect or inconsistency under the indenture, provided that such action does not adversely affect the interests of the holders of any series of debt securities,

• supplement any provisions of the indenture necessary to defease and discharge any series of debt securities, provided that such action does not adversely affect the interests of the holders of any series of debt securities,

• comply with the rules or regulations of any securities exchange or automated quotation system on which any debt securities are listed or traded, or

• add, change or eliminate any provisions of the indenture in accordance with any amendments to the Trust Indenture Act of 1939, provided that the action does not adversely affect the rights or interests of any holder of debt securities. (Section 901)

We may enter into one or more supplemental indentures with the trustee to add to, change or eliminate provisions of the indenture or to modify the rights of the holders of one or more series of debt securities if we obtain the consent of the holders of a majority in principal amount of the outstanding debt securities of each series affected by the supplemental indenture, treated as one class. However, without the consent of the holders of each outstanding debt security affected by the supplemental indenture, we may not enter into a supplemental indenture that:

• changes the stated maturity of the principal of, or any installment of principal of or interest on, any debt security, except to the extent permitted by the indenture,

• reduces the principal amount of, or any premium or interest on, any debt security,

• reduces the amount of principal of an original issue discount security or any other debt security payable upon acceleration of the maturity thereof,

• changes the place or currency of payment of principal, premium, if any, or interest,

• impairs the right to institute suit for the enforcement of any payment on any debt security,

• reduces the percentage in principal amount of outstanding debt securities of any series, the consent of whose holders is required for modification of the indenture, for waiver of compliance with certain provisions of the indenture or for waiver of certain defaults,

• makes certain modifications to the provisions for modification of the indenture and for certain waivers, except to increase the principal amount of debt securities necessary to consent to any such change,

• makes any change that adversely affects the right to convert or exchange any debt security or decreases the conversion or exchange rate or increases the conversion price of any convertible or exchangeable debt security, or

• changes the terms and conditions pursuant to which any series of debt securities is secured in a manner adverse to the holders of the debt securities. (Section 902)

Holders of a majority in principal amount of the outstanding debt securities of any series may waive past defaults or noncompliance with restrictive provisions of the indenture. However, such holders of a majority in principal amount may not waive, and consequently, the consent of holders of each outstanding debt security of a series would be required to:

• waive any default in the payment of principal, premium, if any, or interest, or

16

• waive any covenants and provisions of the indenture that may not be amended without the consent of the holder of each outstanding debt security of the series affected. (Sections 513 and 1006)

To determine whether the holders of the requisite principal amount of the outstanding debt securities have taken an action under the indenture as of a specified date:

• the principal amount of an “original issue discount security” 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,

• if, as of that date, the principal amount payable at the stated maturity of a debt security is not determinable, for example, because it is based on an index, the principal amount of the debt security deemed to be outstanding as of that date will be an amount determined in the manner prescribed for the debt security,

• the principal amount of a debt security denominated in one or more foreign currencies or currency units that will be deemed to be outstanding will be the U.S. dollar ($) equivalent, determined as of that date in the manner prescribed for the debt security, of the principal amount of the debt security or, in the case of a debt security described in the two preceding bullet points, of the amount described above, and

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

An “original issue discount security” means a debt security issued under the indenture which provides for an amount less than the principal amount thereof to be due and payable upon a declaration of acceleration of maturity. Some debt securities, including those for the payment or redemption of which money has been deposited or set aside in trust for the holders and those that have been fully defeased pursuant to Section 1402 of the indenture, will not be deemed to be outstanding. (Section 101)

We will generally be entitled to set any day as a record date for determining the holders of outstanding debt securities of any series entitled to give or take any direction, notice, consent, waiver or other action under the indenture. In limited circumstances, the trustee will be entitled to set a record date for action by holders of outstanding debt securities. If a record date is set for any action to be taken by holders of a particular series, the action may be taken only by persons who are holders of outstanding debt securities of that series on the record date. To be effective, the action must be taken by holders of the requisite principal amount of debt securities within a specified period following the record date. For any particular record date, this period will be 180 days or such shorter period as we may specify, or the trustee may specify, if it set the record date. This period may be shortened or lengthened by not more than 180 days. (Section 104)

Defeasance

When we use the term defeasance, we mean discharge from some or all of our obligations under the indenture. Unless we inform you otherwise in the prospectus supplement, if we deposit with the trustee funds or government securities sufficient to make payments on the debt securities of a series on the dates those payments are due and payable, then, at our option, either of the following will occur:

• we will be discharged from our obligations with respect to the debt securities of that series (“legal defeasance”), or

• we will no longer have any obligation to comply with the restrictive covenants under the indenture, and the related events of default will no longer apply to us, but some of our other obligations under the indenture and the debt securities of that series, including our obligation to make payments on those debt securities, will survive.

17

If we effect legal defeasance of a series of debt securities, the holders of the debt securities of the series affected will not be entitled to the benefits of the indenture, except for our obligations to:

• register the transfer or exchange of debt securities,

• replace mutilated, destroyed, lost or stolen debt securities, and

• maintain paying agencies and hold moneys for payment in trust.

Unless we inform you otherwise in the prospectus supplement, we will be required to deliver to the trustee an opinion of counsel that the deposit and related defeasance would not cause the holders of the debt securities to recognize gain or loss for federal income tax purposes and that the holders would be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if the deposit and related defeasance had not occurred. If we elect legal defeasance, that opinion of counsel must be based upon a ruling from the United States Internal Revenue Service or a change in law to that effect. (Sections 1401, 1402, 1403 and 1404)

Satisfaction And Discharge

We may discharge our obligations under the indenture while debt securities remain outstanding if (1) all outstanding debt securities issued under the indenture have become due and payable, (2) all outstanding debt securities issued under the indenture have or will become due and payable at their scheduled maturity within one year or (3) all outstanding debt securities issued under the indenture are scheduled for redemption in one year, and in each case, we have deposited with the trustee an amount sufficient to pay and discharge all outstanding debt securities issued under the indenture on the date of their scheduled maturity or the scheduled date of redemption and we have paid all other sums payable under the Indenture. (Section 401)

Notices

Holders will receive notices by mail at their addresses as they appear in the security register. (Section 106)

Title

We may treat the person in whose name a debt security is registered on the applicable record date as the owner of the debt security for all purposes, whether or not it is overdue. (Section 309)

Governing Law

New York law will govern the indenture and the debt securities. (Section 112)

Regarding the Trustee

The Bank of New York Mellon Trust Company, National Association, successor to JPMorgan Chase Bank, National Association, is the trustee, security registrar and paying agent under the indenture. As of March 31, 2020, the trustee served as trustee for approximately $2.2 billion aggregate principal amount of our debt securities. In addition, the trustee served as trustee or fiscal agent for debt securities of our affiliates aggregating approximately $7.3 billion as of March 31, 2020.

We and our affiliates maintain brokerage and other relationships with the trustee and its affiliates in the normal course of business.

If an event of default occurs under the indenture and is continuing, the trustee will be required to use the degree of care and skill of a prudent person in the conduct of that person’s own affairs. The trustee will become obligated to exercise any of its powers under the indenture at the request of any of the holders of any debt securities issued under the indenture only after those holders have offered the trustee indemnity satisfactory to it.

18

If the trustee becomes one of our creditors, its rights to obtain payment of claims in specified circumstances, or to realize for its own account on certain property received in respect of any such claim as security or otherwise will be limited under the terms of the indenture pursuant to the provisions of the Trust Indenture Act. (Section 613) The trustee may engage in certain other transactions; however, if the trustee acquires any conflicting interest (within the meaning specified under the Trust Indenture Act), it will be required to eliminate the conflict or resign. (Section 608)

PLAN OF DISTRIBUTION

We may sell the offered debt securities in and outside the United States:

• through underwriters or dealers,

• directly to purchasers, including our affiliates,

• through agents, or

• through a combination of any of these methods.

The prospectus supplement will include the following information:

• the terms of the offering,

• the names of any underwriters or agents,

• the name or names of any managing underwriter or underwriters,

• the purchase price of the debt securities,

• the net proceeds to us from the sale of the debt securities,

• any delayed delivery arrangements,

• any underwriting discounts, commissions and other items constituting underwriters’ compensation,

• any initial public offering price,

• any discounts or concessions allowed or reallowed or paid to dealers, and

• any commissions paid to agents.

Sale Through Underwriters or Dealers

If we use underwriters in the sale, the underwriters will acquire the debt securities for their own account. The underwriters may resell the debt securities from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. Underwriters may offer debt securities to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. Unless we inform you otherwise in the prospectus supplement, the obligations of the underwriters to purchase the debt securities will be subject to certain conditions, and the underwriters will be obligated to purchase all the offered debt securities if they purchase any of them. The underwriters may change from time to time any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers.

During and after an offering through underwriters, the underwriters may purchase and sell the debt securities in the open market. These transactions may include overallotment and stabilizing transactions and purchases to cover syndicate short positions created in connection with the offering. The underwriters also may impose a penalty bid, which means that selling concessions allowed to syndicate members or other broker-dealers for the offered debt securities sold for their account may be reclaimed by the syndicate if the offered debt securities are repurchased by the syndicate in stabilizing or covering transactions. These activities may stabilize, maintain or otherwise affect the market price of the offered debt securities, which may be higher than the price that might otherwise prevail in the open market. If commenced, the underwriters may discontinue these activities at any time.

If we use dealers in the sale of debt securities, we may sell the debt securities to them as principals. They may then resell those debt securities to the public at varying prices determined by the dealers at the time of resale. The dealers participating in any sale of the debt securities may be deemed to be underwriters within the

20

meaning of the Securities Act of 1933 with respect to any sale of these securities. We will include in the prospectus supplement the names of the dealers and the terms of the transaction.

Direct Sales and Sales Through Agents

We may sell the debt securities directly. In that event, no underwriters or agents would be involved. We may also sell the debt securities through agents we designate from time to time. In the prospectus supplement, we will name any agent involved in the offer or sale of the offered debt securities, and we will describe any commissions payable by us to the agent. Unless we inform you otherwise in the prospectus supplement, any agent will agree to use its reasonable best efforts to solicit purchases for the period of its appointment.

We may sell the debt securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act of 1933 with respect to any sale of those debt securities. We will describe the terms of any such sales in the prospectus supplement.

Delayed Delivery Contracts

If we so indicate in the prospectus supplement, we may authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase debt securities from us at the public offering price under delayed delivery contracts. These contracts would provide for payment and delivery on a specified date in the future. The contracts would be subject only to those conditions described in the prospectus supplement. The prospectus supplement will describe the commission payable for solicitation of those contracts.

Remarketing

We may offer and sell any of the offered debt securities in connection with a remarketing upon their purchase, in accordance with a redemption or repayment by their terms or otherwise by one or more remarketing firms acting as principals for their own accounts or as our agents. We will identify any remarketing firm, the terms of any remarketing agreement and the compensation to be paid to the remarketing firm in the prospectus supplement. Remarketing firms may be deemed underwriters under the Securities Act of 1933.

Derivative Transactions

We may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell debt securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third parties may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of securities, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of securities. The third parties in these sale transactions will be underwriters and will be identified in the applicable prospectus supplement or in a post-effective amendment to the registration statement of which this prospectus forms a part.

General Information

We may have agreements with the agents, dealers and underwriters to indemnify them against certain civil liabilities, including liabilities under the Securities Act of 1933, or to contribute with respect to payments that the agents, dealers or underwriters may be required to make. Agents, dealers and underwriters may be customers of, engage in transactions with or perform services for us in the ordinary course of their businesses.

To the extent required, this prospectus may be amended or supplemented from time to time to describe a particular plan of distribution. The place and time of delivery for the debt securities in respect of which this prospectus is delivered will be set forth in the accompanying prospectus supplement.

21

Each series of offered debt securities will be a new issue and will have no established trading market. We may elect to list any series of offered debt securities on an exchange, but we are not obligated to do so. It is possible that one or more underwriters may make a market in a series of offered debt securities. However, they will not be obligated to do so and may discontinue market making at any time without notice. We cannot assure you that a liquid trading market for any of our offered debt securities will develop.

22

Ryan, Esq., our Senior Vice President and General Counsel, or Monica Karuturi, Esq., our Vice President and Deputy General Counsel, may pass upon other legal matters for us.
