See “Supplemental Description of the Senior Notes—Optional Redemption” in this prospectus supplement.

Sinking Fund None.

S-5

Reopening of the Series We may, from time to time, without the consent of the holders of the applicable series of notes offered hereby, reopen either or both series of the notes and issue additional notes of the applicable series with the same terms (including the maturity date and interest payment terms) as the applicable notes offered hereby, except for the price to the public, the issue date and, if applicable, the first interest accrual and payment dates. Any such additional notes, together with the notes of the applicable series offered by this prospectus supplement, will constitute a single series under the Indenture (as defined herein) and will have the same CUSIP provided they are fungible for U.S. federal income tax purposes.

Use of Proceeds We intend to use the aggregate net proceeds from the sale of the notes offered by this prospectus supplement to repay a portion of our outstanding short-term borrowings and for other general corporate purposes. As of September 30, 2021, we had $1.75 billion of short-term borrowings outstanding on a consolidated basis, which included $1.73 billion of short-term borrowings outstanding at the Company. Until the net proceeds from the sale of the notes have been used, we may invest them temporarily in interest-bearing obligations. See “Use of Proceeds” in this prospectus supplement.

Conflicts of Interest Affiliates of certain of the underwriters are lenders under our 364-day term loan that matures on February 17, 2022 (the “Term Loan”) or may hold our outstanding commercial paper, both of which are expected to be partially repaid with a portion of the aggregate net proceeds of this offering. To the extent of any such repayment, affiliates of certain of the underwriters will receive 5% or more of the net proceeds of this offering. Accordingly, any such underwriter will be deemed to have a conflict of interest under Rule 5121 (Public Offerings of Securities with Conflicts of Interest) of the Financial Industry Regulatory Authority, Inc. (“FINRA”). Accordingly, this offering will be conducted in accordance with FINRA Rule 5121. See “Underwriting—Conflicts of Interest” in this prospectus supplement.

Trustee Wells Fargo Bank, National Association.

Governing Law The indenture is, and the notes will be, governed by and construed in accordance with the laws of the State of Minnesota.

S-6

RISK FACTORS

You should carefully consider the risks and uncertainties described below as well as any cautionary language or other information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus, including the information under the caption “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2020, as modified by our other SEC filings filed after such annual report, before purchasing the notes offered by this prospectus supplement. Those risks and the risks set forth below are those that we consider to be the most significant to your decision whether to invest in the notes. If any of the events described therein or set forth below occur, our business, financial condition or results of operations could be materially harmed. In addition, we may not be able to make payments on the notes, and this could result in your losing all or part of your investment.

Risks Related to the Notes

Any lowering of the credit ratings on the notes would likely reduce their value.

As described under the caption “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2020, our credit ratings could be lowered or withdrawn entirely by a rating agency in the future. Any lowering of the credit ratings on our notes would likely reduce the value of the notes offered by this prospectus supplement.

We must rely on cash from our subsidiaries to make payments on the notes.

We are a holding company and thus our investments in our subsidiaries are our primary assets. Substantially all of our operations are conducted by our subsidiaries. Consequently, our operating cash flow and our ability to service our indebtedness depends upon the operating cash flow of our subsidiaries and the payment of funds by them to us in the form of dividends. Our subsidiaries are separate legal entities that have no obligation to pay any amounts due pursuant to our obligations or to make any funds available for that purpose, whether by dividends or otherwise. In addition, each subsidiary’s ability to pay dividends to us depends on any statutory and/or contractual restrictions that may be applicable to such subsidiary, which may include requirements to maintain minimum levels of equity ratios, working capital or other assets.

Our utility subsidiaries are regulated by various state utility commissions, which generally possess broad powers to ensure that the needs of the utility customers are being met. To the extent that the state commissions attempt to impose restrictions on the ability of our utility subsidiaries to pay dividends to us, it could adversely affect our ability to make payments on the notes.

As a holding company, our ability to participate in any distribution of assets of a subsidiary is structurally subordinate to the claims of creditors of the subsidiary. As of September 30, 2021, our subsidiaries had approximately $36.23 billion of indebtedness and other liabilities outstanding.

The notes offered by this prospectus supplement have no prior public market, and we cannot assure you that any public market will develop or be sustained after the offering.

Although the notes offered by this prospectus supplement generally may be resold or otherwise transferred by holders who are not our affiliates, each series of the notes will constitute a new issue of securities without an established trading market. We have been advised by the underwriters that they may make a market in either or both series of the notes, but they have no obligation to do so and may discontinue market making at any time for either or both series of the notes without providing notice. There can be no assurance that a market for either or both series of the notes will develop or, if it does develop, that it will continue. If an active public market does not develop, the market prices and liquidity of the notes may be adversely affected. Furthermore, we do not intend to apply for listing of either series of the notes on any securities exchange or seek their quotation on any automated quotation system.

S-7

USE OF PROCEEDS

We estimate that our aggregate net proceeds from the sale of the notes, less the underwriting discount and other offering expenses payable by us, will be approximately $791,207,000. We intend to use the aggregate net proceeds from the sale of the notes offered by this prospectus supplement to repay a portion of our outstanding short-term borrowings and for other general corporate purposes. As of September 30, 2021, we had $1.75 billion of short-term borrowings outstanding on a consolidated basis, which included $1.73 billion of short-term borrowings outstanding at the Company, with a weighted average annual interest rate of 0.5604%. Of these short-term borrowings at the Company, $1.20 billion was drawn under the Term Loan and $529 million represented outstanding commercial paper. Until the net proceeds from the sale of the notes have been used, we may invest them temporarily in interest-bearing obligations.

S-8

SELECTED CONSOLIDATED FINANCIAL DATA

The following selected consolidated financial data as of December 31, 2020 and 2019, and for the years ended December 31, 2020, 2019, and 2018, has been derived from our audited consolidated financial statements and the related notes.

SUPPLEMENTAL DESCRIPTION OF THE SENIOR NOTES

Please read the following information concerning the notes offered by this prospectus supplement in conjunction with the statements under the caption “Description of Senior Debt Securities” in the accompanying prospectus, which the following information supplements and, in the event of any inconsistencies, supersedes. The following description does not purport to be complete and is subject to, and is qualified in its entirety by reference to, the description in the accompanying prospectus and the Indenture, dated as of December 1, 2000, as supplemented (the “Indenture”), between us and Wells Fargo Bank, National Association, as trustee (the “Trustee”), including Supplemental Indenture No. 15, to be dated as of November 3, 2021. The Indenture is described in the accompanying prospectus and is filed as an exhibit to the registration statement under which the notes are being offered and sold. As of September 30, 2021, there were nine series of debt securities in an aggregate principal amount of approximately $4.38 billion outstanding under the Indenture.

General

We will offer $500,000,000 principal amount of the 2027 Notes, as a series of notes under the Indenture. The entire principal amount of the 2027 Notes will mature and become due and payable, together with any accrued and unpaid interest thereon, on March 15, 2027.

We will offer $300,000,000 principal amount of the 2031 Notes, as a series of notes under the Indenture. The entire principal amount of the 2031 Notes will mature and become due and payable, together with any accrued and unpaid interest thereon, on November 15, 2031.

Interest Payments

The 2027 Notes will bear interest at the annual rate set forth on the cover page of this prospectus supplement from November 3, 2021, payable semi-annually on March 15 and September 15 of each year, beginning on March 15, 2022, to the person in whose name the 2027 Note is registered at the close of business on the March 1 and September 1 immediately preceding such March 15 and September 15.

The 2031 Notes will bear interest at the annual rate set forth on the cover page of this prospectus supplement from November 3, 2021, payable semi-annually on May 15 and November 15 of each year, beginning on May 15, 2022, to the person in whose name the 2031 Note is registered at the close of business on the May 1 and November 1 immediately preceding such May 15 and November 15.

So long as the notes are in book-entry only form, we will wire any payments of principal, interest and premium to The Depository Trust Company (“DTC”), as depository (the “Depository”), or its nominee. See “Book-Entry System” in the accompanying prospectus for a discussion of the procedures for payment to the beneficial owners of the notes. The amount of interest payable will be computed on the basis of a 360-day year of twelve 30-day months. In the event that any date on which interest is payable on the notes is not a business day, then payment of the interest payable on such date may be made on the next succeeding business day (and without any interest or other payment in respect of any such delay), with the same force and effect as if made on such date. The term “business day” means each Monday, Tuesday, Wednesday, Thursday and Friday that is not a day on which banking institutions or trust companies in the Borough of Manhattan, the City and State of New York, or in the city where the corporate trust office of the Trustee is located, are obligated or authorized by law or executive order to close.

Reopening of Series

We may, from time to time, without the consent of the holders of the applicable series of notes offered by this prospectus supplement, reopen either or both series of the notes and issue additional notes of the applicable series with the same terms (including the maturity date and interest payment terms) as the applicable notes

offered by this prospectus supplement, except for the price to the public, the issue date and, if applicable, the first interest accrual and payment dates. Any such additional notes, together with the notes of the applicable series offered by this prospectus supplement, will constitute a single series under the Indenture and will have the same CUSIP provided they are fungible for U.S. federal income tax purposes.

Optional Redemption

We may redeem, in whole or in part, one series of the notes offered hereby without redeeming the other series.

At any time prior to February 15, 2027, the 2027 Par Call Date, we may redeem, in whole or in part, the 2027 Notes at a “make whole” redemption price equal to the greater of (1) 100% of the principal amount of such 2027 Notes being redeemed and (2) the sum of the present values of the remaining scheduled payments of principal and interest on the 2027 Notes being redeemed that would be due if such 2027 Notes matured on the 2027 Par Call Date (excluding the portion of any such accrued and unpaid interest to but excluding the date fixed for redemption), discounted to but excluding the date fixed for redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below) applicable to the 2027 Notes plus 10 basis points plus, in each case, accrued and unpaid interest thereon to but excluding the date fixed for redemption. At any time on or after the 2027 Par Call Date, we may redeem, in whole or in part, the 2027 Notes, at 100% of the principal amount of the 2027 Notes being redeemed plus accrued and unpaid interest thereon to but excluding the date fixed for redemption.

At any time prior to May 15, 2031, the 2031 Par Call Date, we may redeem, in whole or in part, the 2031 Notes at a “make whole” redemption price equal to the greater of (1) 100% of the principal amount of such 2031 Notes being redeemed and (2) the sum of the present values of the remaining scheduled payments of principal and interest on the 2031 Notes being redeemed that would be due if such 2031 Notes matured on the 2031 Par Call Date (excluding the portion of any such accrued and unpaid interest to but excluding the date fixed for redemption), discounted to but excluding the date fixed for redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below) applicable to the 2031 Notes plus 15 basis points plus, in each case, accrued and unpaid interest thereon to but excluding the date fixed for redemption. At any time on or after the 2031 Par Call Date, we may redeem, in whole or in part, the 2031 Notes, at 100% of the principal amount of the 2031 Notes being redeemed plus accrued and unpaid interest thereon to but excluding the date fixed for redemption.

For purposes of these redemption provisions with respect to the notes, the following terms have the following meanings:

“Comparable Treasury Issue” means the U.S. Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the applicable series of notes being redeemed (assuming, for this purpose, that the 2027 Notes matured on the 2027 Par Call Date and the 2031 Notes matured on the 2031 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 the notes being redeemed.

“Comparable Treasury Price” means with respect to any redemption date of the notes (1) the average of the Reference Treasury Dealer Quotations for such date fixed for redemption, after excluding the highest and lowest of such Reference Treasury Dealer Quotations for such date fixed for redemption, or (2) if the Independent Investment Banker obtains fewer than four of such Reference Treasury Dealer Quotations for the date fixed for redemption, the average of all of such Reference Treasury Dealer Quotations for the date fixed for redemption.

S-11

“Independent Investment Banker” means one of the Reference Treasury Dealers or their respective successors or, if such firms or their respective successors are unwilling or unable to select the applicable Comparable Treasury Issue, an independent investment banking institution of national standing appointed by us.

“Primary Treasury Dealer” means any primary U.S. Government securities dealer in the United States.

“Reference Treasury Dealer” means (1) each of BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, and any other Primary Treasury Dealer designated by, and not affiliated with, BofA Securities, Inc., Citigroup Global Markets Inc., and Morgan Stanley & Co. LLC, or their respective affiliates or successors, provided, however, that if any of the foregoing, or any of their respective designees, ceases to be a Primary Treasury Dealer, we will appoint another Primary Treasury Dealer as a substitute and (2) any other Primary Treasury Dealer selected by us after consultation with an Independent Investment Banker.

“Reference Treasury Dealer Quotations” means, for any Reference Treasury Dealer and any date fixed for redemption, the average, as determined by an 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 an Independent Investment Banker by the Reference Treasury Dealer at 5:00 p.m., Eastern time, on the third business day preceding the date fixed for redemption.

“Treasury Rate” means, with respect to any date fixed for redemption, the rate per annum equal to the semi-annual equivalent yield to maturity of the applicable Comparable Treasury Issue, calculated using a price for such Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the applicable Comparable Treasury Price for such date fixed for redemption. The Treasury Rate will be calculated on the third business day preceding the date fixed for redemption.

Redemption Procedures

If we elect to redeem fewer than all of a series of the notes, the Trustee will select, in a manner as it deems fair and appropriate (and in accordance with the procedures of the Depository), the particular notes of such series or portions of them to be redeemed. Notice of redemption will be given by mail not less than 10 days or more than 60 days prior to the date fixed for redemption to the holders of the applicable series of the notes to be redeemed (which, as long as the notes are held in the book-entry only system, will be the Depository, its nominee or a successor depository). On and after the date fixed for redemption (unless we default in the payment of the redemption price and interest accrued thereon to such date), interest on the notes or the portions of them so called for redemption will cease to accrue.

Sinking Fund

Neither series of the notes will provide for any sinking fund.

Form and Denomination

Global Notes and Denominations

Each series of the notes will be issued as one or more global notes in the name of the Depository or a nominee of the Depository and will be available only in book-entry form. See below and “Book-Entry System” in the accompanying prospectus. The notes of each series will be issued only in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

DTC, Clearstream and Euroclear

Beneficial interests in a global note 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 elect to hold

S-12

interests in a global note through either DTC (in the United States) or Clearstream Banking, S.A. (“Clearstream”), or Euroclear Bank SA/NV (“Euroclear”), in Europe (the “Euroclear Operator”), either directly if they are participants in such systems or indirectly through organizations that are participants in such systems. Clearstream and Euroclear will hold interests on behalf of their participants through customers’ securities accounts in Clearstream’s and Euroclear’s names on the books of their U.S. depositaries, which in turn will hold such interests in customers’ securities accounts in the U.S. depositaries’ names on the books of DTC.

For information regarding DTC and DTC’s procedures, see “Book-Entry System” in the accompanying prospectus. We understand that Clearstream is incorporated under the laws of Luxembourg as a professional depositary. Clearstream holds securities for its customers and facilitates the clearance and settlement of securities transactions between its customers through electronic book-entry changes in accounts of its customers, thereby eliminating the need for physical movement of certificates. Clearstream provides to its customers, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream interfaces with domestic markets in several countries. As a professional depositary, Clearstream is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Section. Clearstream customers are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and other organizations and may include the underwriters. Indirect access to Clearstream is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Clearstream customer either directly or indirectly.

We understand that Euroclear was created in 1968 to hold securities for participants of Euroclear and to clear and settle transactions between Euroclear participants through simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of certificates and any risk from lack of simultaneous transfers of securities and cash. Euroclear provides various other services, including securities lending and borrowing and interfaces with domestic markets in several countries. Euroclear is operated by Euroclear Bank SA/NV (the “Euroclear Operator”), under contract with Euroclear Clearance Systems S.C., a Belgian cooperative corporation (the “Cooperative”). All operations are conducted by the Euroclear Operator, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator, not the Cooperative. The Cooperative establishes policy for Euroclear on behalf of Euroclear participants. Euroclear participants include banks (including central banks), securities brokers and dealers, and other professional financial intermediaries and may include the underwriters. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear participant, either directly or indirectly.

We understand that the Euroclear Operator is licensed by the Belgian Banking and Finance Commission to carry out banking activities on a global basis. As a Belgian bank, it is regulated and examined by the Belgian Banking and Finance Commission.

We have provided the descriptions of the operations and procedures of DTC, Clearstream and Euroclear in this prospectus supplement and the accompanying prospectus solely as a matter of convenience. These operations and procedures are solely within the control of those organizations and are subject to change by them from time to time. None of us, the underwriters or the trustee takes any responsibility for these operations or procedures, and you are urged to contact DTC, Clearstream and Euroclear or their participants directly to discuss these matters.

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

The transferor shall also provide or cause to be provided to the Trustee all information necessary to allow the Trustee to comply with any applicable tax reporting obligations, including without limitation any cost basis

S-13

reporting obligations under section 6045 of the Code (as defined below). The Trustee may rely on the information provided to it and shall have no responsibility to verify or ensure the accuracy of such information.

In connection with any proposed transfer outside the book-entry only system, there shall be provided to the Trustee all information necessary to allow the Trustee to comply with any applicable tax reporting obligations, including without limitation any cost basis reporting obligations under section 6045 of the Code. The Trustee may rely on the information provided to it and shall have no responsibility to verify or ensure the accuracy of such information.

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.

Distributions on the notes held beneficially through Clearstream will be credited to cash accounts of its customers in accordance with its rules and procedures, to the extent received by the U.S. depositary for Clearstream.

Securities clearance accounts and cash accounts with the Euroclear Operator are governed by the Terms and Conditions Governing Use of Euroclear and the related Operating Procedures of the Euroclear System, and applicable Belgian law (collectively, the “Terms and Conditions”). The Terms and Conditions govern transfers of securities and cash within Euroclear, withdrawals of securities and cash from Euroclear, and receipts of payments with respect to securities in Euroclear. All securities in Euroclear are held on a fungible basis without attribution of specific certificates to specific securities clearance accounts. The Euroclear Operator acts under the Terms and Conditions only on behalf of Euroclear participants and has no record of or relationship with persons holding through Euroclear participants.

Distributions on the notes held beneficially through Euroclear will be credited to the cash accounts of its participants in accordance with the Terms and Conditions, to the extent received by the U.S. depositary for Euroclear.

Clearance and Settlement Procedures

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. Secondary market trading between Clearstream customers and/or Euroclear participants will occur in the ordinary way in accordance with the applicable rules and operating procedures of Clearstream and Euroclear, as applicable, and will be settled using the procedures applicable to conventional eurobonds in immediately available funds.

Cross-market transfers between persons holding directly or indirectly through DTC, on the one hand, and directly or indirectly through Clearstream customers or Euroclear participants, on the other hand, will be effected through DTC in accordance with DTC rules on behalf of the relevant European international clearing system by the U.S. depositary; however, such cross-market transactions will require delivery of instructions to the relevant European international clearing system by the counterparty in such system in accordance with its rules and procedures and within its established deadlines (European time). The relevant European international clearing system will, if the transaction meets its settlement requirements, deliver instructions to the U.S. depositary to

S-14

take action to effect final settlement on its behalf by delivering or receiving the notes in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Clearstream customers and Euroclear participants may not deliver instructions directly to their U.S. depositaries.

Because of time-zone differences, credits of the notes received in Clearstream or Euroclear as a result of a transaction with a DTC participant will be made during subsequent securities settlement processing and dated the business day following the DTC settlement date. Such credits or any transactions in the notes settled during such processing will be reported to the relevant Clearstream customers or Euroclear participants on such business day. Cash received in Clearstream or Euroclear as a result of sales of the notes by or through a Clearstream customer or a Euroclear participant to a DTC participant will be received with value on the DTC settlement date but will be available in the relevant Clearstream or Euroclear cash account only as of the business day following settlement in DTC.

Events of Default

See “Description of Senior Debt Securities—Events of Default and Remedies” in the accompanying prospectus.

Same-Day Settlement and Payment

The underwriters will pay us and settle for the notes in immediately available funds. We will make all payments of principal and interest in immediately available funds.

The notes will trade in DTC’s same-day funds settlement system until maturity or until the notes are issued in certificated form, and secondary market trading activity in the notes will therefore be required by DTC to settle in immediately available funds. No assurance can be given as to the effect, if any, of settlement in immediately available funds on trading activity in the notes.

Governing Law

The Indenture is, and the notes will be, governed by and construed in accordance with the laws of the State of Minnesota.

Concerning the Trustee

We now have, and may from time to time conduct, other banking transactions, including lending transactions, or maintaining deposit accounts with Wells Fargo Bank, National Association, the Trustee in the ordinary course of business. Wells Fargo Bank, National Association, in addition to being the Trustee under the Indenture, is one of the lenders under the Term Loan, and a portion of the net proceeds from the sale of the notes will be used to repay borrowings outstanding under the Term Loan. An affiliate of the Trustee is an underwriter participating in this offering. The Trustee will be permitted to engage in other transactions with us; however, if it acquires any conflicting interest as defined in the Trust Indenture Act of 1939, it may be required to resign as Trustee under the Indenture. In that event, we would be required to appoint a successor trustee for the notes. Subject to the provisions of the Indenture relating to the duties of the Trustee, the Trustee is under no obligation to exercise any of its rights or powers under the Indenture at the request, order or direction of any of the holders, unless such holders have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which may be incurred by such exercise.

Wells Fargo Bank, National Association is a wholly-owned subsidiary of Wells Fargo & Company, a U.S. bank holding company. On March 23, 2021, Wells Fargo & Company announced that it had entered into a definitive agreement with Computershare Ltd. (“Computershare”) to sell substantially all of its Corporate Trust Services (“CTS”) business. The transaction is expected to close in the second half of 2021, subject to customary

S-15

closing conditions and regulatory approvals. Virtually all corporate trust services employees of Wells Fargo Bank, National Association along with most existing CTS systems, technology and offices, are expected to transfer to one or more Computershare-affiliated entities as part of the sale. Subject to any requirements set forth in the definitive agreement between Wells Fargo & Company and Computershare, Wells Fargo Bank, National Association intends to transfer to Computershare Trust Company, N.A. or another Computershare-affiliated entity its duties, obligations and rights with respect to the transaction described herein on or after the closing of the transaction with Computershare. In the event that the transfer of any duties, obligations and rights of Wells Fargo Bank, National Association to Computershare Trust Company, N.A. or another Computershare-affiliated entity does not occur on the closing of the transaction with Computershare, Wells Fargo Bank, National Association intends to continue to perform such duties, obligations and rights through a Computershare-affiliated entity as its agent.

S-16

CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following discussion is a summary of certain U.S. federal income tax consequences relevant to the purchase, beneficial ownership and disposition of the notes offered by this prospectus supplement. This summary is based on the U.S. Internal Revenue Code of 1986, as amended (the “Code”), Treasury regulations promulgated thereunder, administrative pronouncements of the U.S. Internal Revenue Service (the “IRS”), and judicial decisions, all as currently in effect and all of which are subject to change and to different interpretations. Changes to any of the foregoing authorities could apply on a retroactive basis, and could affect the U.S. federal income tax consequences described below. We have not sought and will not seek a ruling from the IRS with respect to the matters discussed in this section, and we cannot assure you that the IRS will not challenge one or more of the tax consequences described below.

This summary does not address all of the U.S. federal income tax considerations that may be relevant to a particular investor’s circumstances (such as the effects of section 451(b) of the Code conforming the timing of certain income accruals to financial statements) and does not discuss any aspect of U.S. federal tax law other than income tax law (such as estate or gift tax law) or any state, local or non-U.S. tax consequences of the purchase, beneficial ownership and disposition of the notes. This summary addresses only notes purchased for cash pursuant to this offering at their “issue price” (i.e., the first price at which a substantial amount of the notes are sold to investors, excluding sales to bond houses, brokers or similar persons or organizations acting in the capacity as underwriters, placement agents or wholesalers) and held as capital assets and does not address U.S. federal income tax considerations applicable to investors that may be subject to special tax rules, such as:

• traders in securities electing mark-to-market treatment or securities dealers or brokers;

• banks, thrifts or other financial institutions;

• insurance companies;

• regulated investment companies or real estate investment trusts;

• tax-exempt organizations;

• retirement plans;

• persons holding the notes as part of a “straddle,” “hedge,” “synthetic security” or “conversion transaction” for U.S. federal income tax purposes, or as part of some other integrated investment;

• entities or arrangements treated as partnerships or other pass-through entities and investors therein;

• persons required to pay the alternative minimum tax;

• certain former citizens or former residents of the United States;

• persons deemed to sell the notes under the constructive sale provisions of the Code;

• “passive foreign investment companies” or “controlled foreign corporations” (each within the meaning of the Code); or

• “U.S. Holders” (as defined below) whose functional currency is not the U.S. dollar.

As used herein, a “U.S. Holder” is a beneficial owner of the notes that is, for U.S. federal income tax purposes, (i) an individual citizen or resident of the United States, (ii) a corporation created or organized in or under the laws of the United States, any state thereof or the District of Columbia, (iii) an estate whose income is subject to U.S. federal income tax regardless of its source, or (iv) a trust if (A) a United States court has the authority to exercise primary supervision over the administration of the trust and one or more “United States persons” (as defined in the Code) are authorized to control all substantial decisions of the trust or (B) it has a valid election in place to be treated as a United States person.

A “Non-U.S. Holder” is any beneficial owner of the notes that is neither a U.S. Holder nor a partnership (including an entity or arrangement treated as a partnership for U.S. federal income tax purposes).

S-17

If a partnership (or other entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds the notes, the U.S. federal income tax treatment of a partner generally will depend on the status of the partner and the activities of the partnership. A partnership holding the notes, and partners in such a partnership, should consult their own tax advisors with regard to the U.S. federal income tax consequences of the purchase, ownership and disposition of the notes by the partnership.

THIS DISCUSSION OF CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE NOTES IS NOT INTENDED TO BE, NOR SHOULD IT BE CONSTRUED TO BE, LEGAL OR TAX ADVICE TO ANY PARTICULAR PERSON. ACCORDINGLY, ALL PROSPECTIVE INVESTORS ARE URGED TO CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE U.S. FEDERAL, STATE AND LOCAL AND NON-U.S. TAX CONSEQUENCES RELATING TO THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE NOTES BASED ON THEIR PARTICULAR CIRCUMSTANCES THE EFFECTS OF ANY TAX TREATIES AND THE POTENTIAL EFFECTS OF ANY CHANGES IN LAW.

U.S. Federal Income Taxation of U.S. Holders

Payments of Interest. Interest on the notes generally will be taxable to a U.S. Holder as ordinary income at the time that such interest is paid or accrued, in accordance with the U.S. Holder’s regular method of accounting for U.S. federal income tax purposes. If, however, the stated principal amount of the notes exceeds their issue price by at least a statutorily defined de minimis amount, a U.S. Holder (regardless of its method of tax accounting) will be required to include the excess in income as original issue discount as it accrues generally in accordance with a constant yield method before the receipt of cash payments attributable to this income.

It is expected, and this discussion assumes, that the notes will be issued with less than a de minimis amount of original issue discount for U.S. federal income tax purposes.

Sale, Redemption, Retirement or Other Taxable Disposition of the Notes. Upon the sale, redemption, retirement or other taxable disposition of the notes, a U.S. Holder generally will recognize gain or loss equal to the difference between the amount realized upon the sale, redemption, retirement or other taxable disposition (other than amounts representing accrued and unpaid qualified stated interest, which will be taxable as ordinary interest income to the extent not previously included in gross income) and the U.S. Holder’s adjusted tax basis in the notes. In general, the U.S. Holder’s adjusted tax basis in the notes will equal the U.S. Holder’s initial investment in the notes, reduced by any cash payments previously received in respect of the notes (other than qualified stated interest payments). Such gain or loss generally will be capital gain or loss and will be long-term capital gain or loss if at the time of sale, redemption, retirement or other taxable disposition the notes have been held for more than one year. Under current U.S. federal income tax law, certain non-corporate U.S. Holders, including individuals, are eligible for preferential rates of U.S. federal income taxation in respect of long-term capital gains. The deductibility of capital losses is subject to limitations.

Medicare Tax. A U.S. Holder that is an individual or estate, or a trust that does not fall into a special class of trusts that is exempt from such tax, is subject to a 3.8% tax on the lesser of (1) the U.S. Holder’s “net investment income” (in the case of individuals) or “undistributed net investment income” (in the case of estates and trusts) for the relevant taxable year and (2) the excess of the U.S. Holder’s “modified adjusted gross income” (in the case of individuals) or “adjusted gross income” (in the case of estates and trusts) for the taxable year over a certain threshold (which, in the case of individuals, will be between $125,000 and $250,000, depending on the individual’s circumstances). A U.S. Holder’s net investment income will generally include its interest income from the notes and net gain from the disposition of the notes, unless such interest income and net gain is derived in the ordinary course of the conduct of a trade or business (other than a trade or business that consists of certain passive or trading activities). Net investment income may, however, be reduced by properly allocable deductions to such income. U.S. Holders that are individuals, estates or trusts are urged to consult their tax advisors regarding the applicability of the Medicare tax to their income and gains from the notes.

S-18

U.S. Federal Income Taxation of Non-U.S. Holders

Payments of Interest. Subject to the discussion below concerning backup withholding and FATCA, payments of interest on the notes to any Non-U.S. Holder generally will be exempt from U.S. federal income tax and the 30% U.S. federal withholding tax (or lower applicable treaty rate), provided that:

• the Non-U.S. Holder is not a “10-percent shareholder” of us within the meaning of Section 871(h)(3)(B) of the Code;

• the interest is not effectively connected with the conduct by the Non-U.S. Holder of a trade or business within the United States (or, if a tax treaty applies, is not attributable to a permanent establishment or fixed base maintained by the Non-U.S. Holder in the United States); and

• the certification requirement has been fulfilled with respect to the beneficial owner, as discussed below.

The certification requirement referred to above will be fulfilled if (i) the beneficial owner of the notes certifies on a properly executed IRS Form W-8BEN or W-8BEN-E, as applicable, or applicable successor form, under penalties of perjury, that such beneficial owner is not a United States person, provides its name and address and certifies the other relevant factual information supporting its exemption, and (ii) the beneficial owner provides IRS Form W-8BEN or W-8BEN-E, as applicable, or applicable successor form to the applicable withholding agent, or in the case of notes held on behalf of the beneficial owner by a securities clearing organization, bank, or other financial institution holding customers’ securities in the ordinary course of its trade or business, such financial institution provides the applicable withholding agent with a statement that it has received the IRS Form W-8BEN or W-8BEN-E, as applicable, or applicable successor form, from the beneficial owner and furnishes the applicable withholding agent with a copy. Prospective investors should consult their tax advisors regarding possible additional reporting requirements.

If a Non-U.S. Holder does not satisfy the foregoing requirements, such Non-U.S. Holder generally will be subject to the 30% U.S. federal withholding tax, unless it provides either (i) a properly executed IRS Form W-8BEN or W-8BEN-E, as applicable, or applicable successor form, establishing an exemption from (or a reduction of) withholding under an applicable income tax treaty or (ii) a properly executed IRS Form W-8ECI, or applicable successor form, certifying that interest paid on the notes is not subject to withholding tax because the interest is effectively connected with the Non-U.S. Holder’s conduct of a trade or business in the United States (as described below under “—Income or Gains Effectively Connected with a U.S. Trade or Business”).

Sale, Redemption, Retirement or Other Taxable Disposition of the Notes. Subject to the discussion below concerning backup withholding and FATCA, a Non-U.S. Holder generally will not be subject to U.S. federal income tax or the 30% U.S. federal withholding tax on gain realized on the sale, redemption, retirement or other taxable disposition of the notes, unless:

• the Non-U.S. Holder is an individual who is present in the U.S. for 183 days or more in the taxable year of the disposition and certain other conditions are met; or

• the gain is effectively connected with the Non-U.S. Holder’s conduct of a trade or business in the United States (and, if required by an applicable tax treaty, is attributable to a permanent establishment or fixed base maintained by the Non-U.S. Holder in the United States).

If a Non-U.S. Holder is described in the first bullet above, such Non-U.S. Holder generally will be subject to U.S. federal income tax at a rate of 30% on the amount by which such Non-U.S. Holder’s capital gains allocable to United States sources, including gain from such disposition, exceed any capital losses allocable to United States sources, except as otherwise specified by an applicable income tax treaty.

If a Non-U.S. Holder is described in the second bullet above, such Non-U.S. Holder generally will be subject to tax as described below under “—Income or Gains Effectively Connected with a U.S. Trade or Business.”

S-19

To the extent the amount realized on a sale, redemption, retirement or other taxable disposition of the notes is attributable to accrued but unpaid interest on the notes, this amount generally will be treated in the same manner as described in “—Payments of Interest” above.

Income or Gains Effectively Connected with a U.S. Trade or Business. If a Non-U.S. Holder of the notes is engaged in the conduct of a trade or business in the United States, and interest on the notes, or gain realized on its sale, redemption, retirement or other taxable disposition of the notes, is effectively connected with the conduct of such trade or business (and, if required by an applicable tax treaty, is attributable to a permanent establishment or fixed base maintained by the Non-U.S. Holder in the United States), the Non-U.S. Holder will be subject to U.S. federal income tax on its effectively connected income, generally in the same manner as a U.S. Holder (but without regard to the Medicare tax described above). See “Certain U.S. Federal Income Tax Considerations—U.S. Federal Income Taxation of U.S. Holders” above. In addition, a Non-U.S. Holder that is a corporation for U.S. federal income tax purposes may be subject to a 30% branch profits tax (unless reduced or eliminated by an applicable tax treaty) on its effectively connected earnings and profits, subject to certain adjustments.

Backup Withholding and Information Reporting

U.S. Holders. In general, a U.S. Holder (other than an exempt recipient) will be subject to information reporting requirements with respect to payments of principal and interest in respect of, and the proceeds from a sale, redemption, retirement or other disposition before maturity of the notes. Backup withholding (currently at a rate of 24%) will also apply unless such U.S. Holder timely provides the applicable withholding agent with a correct taxpayer identification number and timely certifies under penalties of perjury that it is not subject to backup withholding, as well as certain other information (generally, on IRS Form W-9), or otherwise establishes an exemption.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against a U.S. Holder’s U.S. federal income tax liability, provided the required information is furnished to the IRS on a timely basis. U.S. Holders should consult their tax advisors regarding the application of information reporting and backup withholding rules in their particular situations, the availability of an exemption therefrom and the procedure for obtaining such an exemption, if applicable.

Non-U.S. Holders. In general, a Non-U.S. Holder will be subject to information reporting requirements with respect to payments of interest on the notes and the amount of U.S. federal withholding tax, if any, deducted from those payments. Copies of the information returns reporting such interest payments and any associated U.S. federal withholding tax also may be made available to the tax authorities in the country in which the Non-U.S. Holder resides under the provisions of an applicable tax treaty. A Non-U.S. Holder generally will not be subject to backup withholding with respect to payments that we make on the notes provided that the applicable withholding agent does not have actual knowledge or reason to know that the Non-U.S. Holder is a United States person, and the applicable withholding agent has received from the Non-U.S. Holder an appropriate certification establishing non-U.S. status or other exemption from backup withholding (i.e., IRS Form W-8BEN or W-8BEN-E, as applicable, W-8ECI or other applicable IRS Form W-8 or applicable successor form). Information reporting and, depending on the circumstances, backup withholding will apply to the payment of the proceeds of a sale of the notes that is effected within the United States or effected outside the United States through certain U.S.-related financial intermediaries, unless the Non-U.S. Holder certifies under penalty of perjury as to its non-U.S. status, and the applicable withholding agent does not have actual knowledge or reason to know that the beneficial owner is a United States person, or the Non-U.S. Holder otherwise establishes an exemption.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against a Non-U.S. Holder’s U.S. federal income tax liability, provided the required information is furnished to the IRS on a timely basis. Non-U.S. Holders of the notes should consult their tax advisors regarding the application of information reporting and backup withholding in their particular situation, the availability of an exemption therefrom, and the procedure for obtaining an exemption, if applicable.

S-20

FATCA

Pursuant to the Foreign Account Tax Compliance Act, or “FATCA,” foreign financial institutions (which term includes most foreign banks, hedge funds, private equity funds, mutual funds, securitization vehicles and other investment vehicles) and certain other foreign entities generally must comply with certain information reporting rules with respect to their U.S. account holders and investors or confront a withholding tax on U.S.-source payments made to them (whether received as a beneficial owner or as an intermediary for another party). A foreign financial institution or such other foreign entity that does not comply with the FATCA reporting requirements will generally be subject to a 30% withholding tax with respect to any “withholdable payments.” For this purpose, withholdable payments generally include U.S.-source payments otherwise subject to nonresident withholding tax (e.g., U.S.-source interest) and also include the entire gross proceeds from the sale or other disposition of any debt instruments of U.S. issuers, even if the payment would otherwise not be subject to U.S. nonresident withholding tax (e.g., because it is capital gain). In December 2018, the Treasury Department issued proposed regulations indicating its intent to eliminate the requirements under FATCA of withholding on such gross proceeds (but not interest). Pursuant to those proposed regulations, the issuer and any withholding agent may (but are not required to) rely on this proposed change to FATCA withholding until the final regulations are issued. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States pursuant to FATCA may be subject to different rules with respect to information reporting and related requirements.

We will not pay any additional amounts in respect of any amounts withheld, including pursuant to FATCA. Under certain circumstances, a holder might be eligible for refunds or credits of such taxes. Holders are urged to consult with their own tax advisors regarding the effect, if any, of the FATCA provisions to them based on their particular circumstances.

The preceding discussion of certain U.S. federal income tax consequences is general information only and is not tax advice. Accordingly, you should consult your own tax advisor as to the U.S. federal, state and local and non-U.S. tax consequences to you of purchasing, holding or disposing of the notes, including the applicability of, any tax treaties and any changes or proposed changes in applicable law.

UNDERWRITING

Subject to the terms and conditions set forth in the underwriting agreement dated the date of this prospectus supplement, we have agreed to sell to each of the underwriters named below, for whom BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC are acting as representatives (the “Representatives”), and each of the underwriters has severally, but not jointly, agreed to purchase, the respective principal amount of notes set forth opposite its name below.

Underwriters	Principal Amount of 2027 Notes		Principal Amount of 2031 Notes
BofA Securities, Inc.	$	80,000,000	$	48,000,000
Citigroup Global Markets Inc.		80,000,000		48,000,000

U.S. Bancorp Investments, Inc.		47,500,000		28,500,000
Wells Fargo Securities, LLC		47,500,000		28,500,000
KeyBanc Capital Markets Inc.		28,750,000		17,250,000
PNC Capital Markets LLC		28,750,000		17,250,000
Samuel A. Ramirez & Company, Inc.		12,500,000		7,500,000
Total	$	500,000,000	$	300,000,000

The underwriters have agreed to purchase all of the notes sold under the underwriting agreement if any of the notes are purchased. The underwriting agreement provides that the obligations of the several underwriters to purchase the notes offered by this prospectus supplement are subject to the approval of specified legal matters by their counsel and several other specified conditions. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the non-defaulting underwriters may be increased or the underwriting agreement may be terminated.

The underwriters have advised us that they propose to offer each series of the notes offered by this prospectus supplement to the public at the applicable price to the public set forth on the cover of this prospectus supplement and may offer the notes to certain securities dealers at such price less a concession not in excess of 0.350% of the principal amount of the 2027 Notes and 0.400% of the principal amount of the 2031 Notes. The underwriters may allow, and such dealers may reallow, a concession not in excess of 0.250% of the principal amount of the 2027 Notes and 0.250% of the principal amount of the 2031 Notes on sales to certain other brokers and dealers. After the initial offering of the notes, the underwriters may change the prices to the public and the other selling terms. The offering of the notes by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part.

The following table shows the underwriting discounts that we will pay to the underwriters in connection with this offering of the notes (expressed as a percentage of the principal amount of the applicable series of the notes):

	Paid by the Company
Per 2027 Note		0.600	%
Per 2031 Note		0.650	%

We estimate that our total expenses related to this offering, excluding the underwriting discounts, will be approximately $1,900,000.

S-22

Each series of the notes is a new issue of securities with no established trading market. The underwriters have informed us that they may make a market in the notes from time to time. The underwriters are not obligated to do this, and they may discontinue this market making for either or both series of the notes at any time without notice. Therefore, no assurance can be given concerning the liquidity of the trading market for the notes or that an active market for the notes will develop. We do not intend to apply for listing of either series of the notes on any securities exchange or seek their quotation on any automated quotation system.

In connection with the offering of the notes, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of either or both series of the notes. Specifically, the underwriters may sell a greater number of notes than they are required to purchase in connection with the offering, creating a syndicate short position. In addition, the underwriters may bid for, and purchase, notes in the open market to cover syndicate short positions or to stabilize the prices of the notes. Finally, the underwriting syndicate may reclaim selling concessions allowed for distributing the notes in the offering of the notes, if the syndicate repurchases previously distributed notes in syndicate covering transactions, stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market prices of the notes above independent market levels. Neither we nor any of the underwriters make any representations or predictions as to the direction or magnitude of any effect that the transactions described above may have on the prices of the notes. The underwriters are not required to engage in any of these transactions and may end any of them at any time.

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

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

It is expected that delivery of the notes will be made against payment therefor on or about the date specified on the cover page of this prospectus supplement, which is the third business day following the date of this prospectus supplement (such settlement cycle being referred to as “T+3”). Under Rule 15c6-l under the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in two business days unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes on the date of this prospectus supplement will be required, by virtue of the fact that the notes initially will settle in T+3, to specify an alternative settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of the notes who wish to trade the notes on the date of this prospectus supplement should consult their own advisors.

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include sales and trading, commercial and investment banking, corporate trust, advisory, investment management, investment research, principal investment, hedging, market making, brokerage and other financial and non-financial activities and services. In the ordinary course of their respective businesses, the underwriters and their affiliates have engaged, and may in the future engage, in other investment banking or commercial banking transactions with us and our affiliates, including acting as lenders under our loan facilities and those of some of our affiliates. They have received or will receive customary fees and commissions for these transactions.

In addition, in the ordinary course of their business activities, the underwriters and their 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. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. If any of the underwriters or their affiliates have a lending relationship with us, certain of those underwriters or their affiliates routinely hedge, and certain other of those underwriters or their affiliates may hedge, their credit

S-23

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 such credit default swaps or short positions could adversely affect the future trading prices of the notes offered hereby. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

No action has been or will be taken by us in any jurisdiction other than in the United States that would permit a public offering of the notes or the possession, circulation or distribution of any material relating to us in any jurisdiction where action for such purpose is required. Accordingly, the notes may not be offered or sold, directly or indirectly, nor may any offering material or advertisement in connection with the notes (including this prospectus supplement and the accompanying prospectus and any amendment or supplement hereto) be distributed or published, in or from any country or jurisdiction, except under circumstances that will result in compliance with any applicable rules and regulations of any such country or jurisdiction.

Selling Restrictions

European Economic Area

The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (“EEA”). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); or (ii) a customer within the meaning of Directive 2016/97/EU where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Regulation 2017/1129/EU (as amended, the “Prospectus Regulation”). 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 has been prepared. Offering or selling the notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation. This prospectus supplement and the accompanying prospectus have been prepared on the basis that any offer of notes in any Member State of the EEA will be made pursuant to an exemption under the Prospectus Regulation from the requirement to publish a prospectus. This prospectus supplement and the accompanying prospectus are not prospectuses for the purposes of the Prospectus Regulation.

For the purposes of this provision, the expression an “offer to the public” in relation to any notes in any Member State of the EEA means the communication in any form and by any means of sufficient information on the terms of the offer and any notes to be offered so as to enable an investor to decide to purchase any notes.

United Kingdom

The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the United Kingdom (“UK”). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client, as defined in point (8) of Article 2 of Regulation (EU) No 2017/565 as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018 (as amended, “EUWA”); (ii) a customer within the meaning of the provisions of the Financial Services and Markets Act 2000 (as amended, the “FSMA”) and any rules or regulations made under the FSMA to implement Directive (EU) 2016/97, where that customer would not qualify as a professional client, as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the EUWA; or (iii) not a qualified investor as defined in Article 2 of Regulation 2017/1129/EU as it forms part of domestic law by virtue of the EUWA (the “UK Prospectus Regulation”). Consequently no key information document required by Regulation (EU) No 1286/2014 as it forms part of domestic law by virtue of the EUWA (the “UK PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail

S-24

investors in the UK has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the UK may be unlawful under the UK PRIIPs Regulation. This prospectus supplement and the accompanying prospectus have been prepared on the basis that any offer of notes in the United Kingdom will be made pursuant to an exemption under the UK Prospectus Regulation from the requirement to publish a prospectus. This prospectus supplement and the accompanying prospectus are not prospectuses for the purposes of the UK Prospectus Regulation.

For the purposes of this provision, the expression an “offer to the public” in relation to any notes in the United Kingdom means the communication in any form and by any means of sufficient information on the terms of the offer and any notes to be offered so as to enable an investor to decide to purchase any notes.

In the United Kingdom, this prospectus supplement and the accompanying prospectus are being distributed only to, and is directed only at, and any offer subsequently made may only be directed at persons who are “qualified investors” (as defined in the UK Prospectus Regulation) (i) who have professional experience in matters relating to investments falling within Article 19 (5) of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005, as amended (the “Order”) and/or (ii) who are high net worth companies (or persons to whom it may otherwise be lawfully communicated) falling within Article 49(2)(a) to (e) of the Order (all such persons together being referred to as “relevant persons”) or otherwise in circumstances which have not resulted and will not result in an offer to the public of the notes in the United Kingdom within the meaning of the FSMA. This prospectus supplement and the accompanying prospectus must not be acted on or relied on in the United Kingdom by persons who are not relevant persons. In the United Kingdom, any investment or investment activity to which this prospectus supplement and the accompanying prospectus relates is only available to, and will be engaged in with, relevant persons.

Each underwriter has represented, warranted and agreed that:

(a) it has only communicated or caused to be communicated and will only communicate or cause to be communicated an invitation or inducement to engage in investment activity (within the meaning of Section 21 of the FSMA) received by it in connection with the issue or sale of any notes which are the subject of the offering contemplated by the prospectus supplement and the accompanying prospectus in circumstances in which Section 21(1) of the FSMA does not apply to us; and

(b) it has complied and will comply with all applicable provisions of FSMA with respect to anything done by it in relation to the notes in, from or otherwise involving the United Kingdom.

Canada

The notes may be sold only to purchasers purchasing, or deemed to be purchasing, as principal that are accredited investors, as defined in National Instrument 45-106 Prospectus Exemptions or subsection 73.3(1) of the Securities Act (Ontario), and are permitted clients, as defined in National Instrument 31-103 Registration Requirements, Exemptions and Ongoing Registrant Obligations. Any resale of the notes must be made in accordance with an exemption from, or in a transaction not subject to, the prospectus requirements of applicable securities laws.

Securities legislation in certain provinces or territories of Canada may provide a purchaser with remedies for rescission or damages if this prospectus supplement or the accompanying prospectus (including any amendment hereto or thereto) contains a misrepresentation, provided that the remedies for rescission or damages are exercised by the purchaser within the time limit prescribed by the securities legislation of the purchaser’s province or territory. The purchaser should refer to any applicable provisions of the securities legislation of the purchaser’s province or territory for particulars of these rights or consult with a legal advisor.

Pursuant to section 3A.3 of National Instrument 33-105 Underwriting Conflicts (NI 33-105), the underwriters are not required to comply with the disclosure requirements of NI 33-105 regarding underwriter conflicts of interest in connection with this offering.

S-25

Hong Kong

This prospectus supplement does not constitute nor is it intended to be an offer or invitation to the public in Hong Kong to acquire the notes. The notes have not been and may not and will not be offered or sold in Hong Kong, by means of any document, other than (i) to “professional investors” as defined in the Securities and Futures Ordinance (Cap. 571, Laws of Hong Kong) and any rules made thereunder, or (ii) in other circumstances which do not result in the document being a “prospectus” as defined in the Companies (Winding Up and Miscellaneous Provisions) Ordinance (Cap. 32, Laws of Hong Kong) and which do not constitute an offer to the public within the meaning of that Ordinance. No advertisement, invitation or document relating to the notes has been, may be or will be issued, or has been, may be, or will be in the possession of any person for the purpose of issue (in each case whether in Hong Kong or elsewhere), which is directed at, or the contents of which are likely to be accessed or read by, the public of Hong Kong (except if permitted to do so under the securities laws of Hong Kong) other than with respect to the notes which are or are intended to be disposed of only to persons outside Hong Kong or only to “professional investors” as defined in the Securities and Futures Ordinance (Cap. 571, Laws of Hong Kong) and any rules made thereunder.

The contents of this prospectus supplement and the accompanying prospectus have not been reviewed, endorsed or approved by any Hong Kong regulatory authorities, including the Securities and Futures Commission and the Companies Registry of Hong Kong and neither has it been nor will it be registered with the Registrar of Companies in Hong Kong. The notes may not be offered for subscription to members of the public in Hong Kong. You are advised to exercise caution in relation to the offer. If you are in doubt about any contents of this prospectus supplement and the accompanying prospectus, you should obtain independent professional advice. Each person acquiring the notes will be required, and is deemed by the acquisition of the notes, to confirm that such person is aware of the restriction on offers of the notes described in this prospectus supplement and the relevant offering documents and that such person is not acquiring, and has not been offered any notes in circumstances that contravene any such restrictions and that such person has complied with all relevant laws, rules and regulations applicable to it/him/her and the jurisdiction(s) where such person or its/his/her assets are located.

Japan

The notes have not been and will not be registered under the Financial Instruments and Exchange Act of Japan (Act No. 25 of 1948, as amended; the “FIEA”). Accordingly, the notes or any interest therein may not be offered or sold, directly or indirectly, in Japan or to, or for the benefit of, any resident of Japan (which term as used herein means any person resident in Japan, including any corporation or other entity organized under the laws of Japan), or to others for re-offering or resale, directly or indirectly, in Japan or to, or for the benefit of, any resident of Japan, except pursuant to an exemption from the registration requirements of, and otherwise in compliance with, the FIEA and any other applicable laws, regulations and ministerial guidelines of Japan in effect at the relevant time.

ABOUT THIS PROSPECTUS

This document is called a “prospectus” and it provides you with a general description of the securities we may offer. Each time we sell securities under this prospectus, we will provide a prospectus supplement containing specific information about the terms of the securities being offered. That prospectus supplement may include a discussion of any risk factors or other special considerations that apply to those securities. The prospectus supplement may also add, update or change the information in this prospectus. If there is any inconsistency between the information in this prospectus and in the prospectus supplement, you should rely on the information in the prospectus supplement. You should read this prospectus and the applicable prospectus supplement together with the additional information described under the caption “Where You Can Find More Information.” We may also prepare free writing prospectuses that describe particular securities. Any free writing prospectus should also be read in connection with this prospectus and with the prospectus supplement referred to therein. For purposes of this prospectus, any reference to an applicable prospectus supplement may also refer to a free writing prospectus, unless the context otherwise requires.

This prospectus is part of a registration statement that we filed with the Securities and Exchange Commission (the “SEC”) using a shelf registration process. By using this process, we may, from time to time, sell any combination of the securities described in this prospectus in one or more offerings. We may offer any of the following securities: senior debt securities, subordinated debt securities, or junior subordinated debt securities, each of which may be convertible into our common stock, common stock, preferred stock, depositary shares, warrants, rights, purchase contracts and units. As permitted by SEC rules, this prospectus does not contain all of the information included in the registration statement and the accompanying exhibits and schedules we filed with the SEC. You should read the registration statement and the related exhibits and schedules for more information about us and our securities. The registration statement and the related exhibits and schedules can be read at the SEC’s website at www.sec.gov.

The distribution of this prospectus and the applicable prospectus supplement and the offering of the securities in certain jurisdictions may be restricted by law. Persons into whose possession this prospectus and the applicable prospectus supplement come should inform themselves about and observe any such restrictions. This prospectus and the applicable prospectus supplement do not constitute, and may not be used in connection with, an offer or solicitation by anyone in any jurisdiction in which such offer or solicitation is not authorized or in which the person making such offering or solicitation is not qualified to do so or to any person to whom it is unlawful to make such offer or solicitation.

This prospectus, the applicable prospectus supplement and any free writing prospectus that we prepare or authorize contain and incorporate by reference information that you should consider when making your investment decision.

DESCRIPTION OF SENIOR DEBT SECURITIES

The description below contains summaries of selected provisions of the indenture, including supplemental indentures, under which the senior debt securities (referred to herein as “senior debt securities”) may be issued. These summaries are not complete. The indenture and the form of the supplemental indenture applicable to the senior debt securities have been filed as exhibits to the registration statement. You should read them for provisions that may be important to you. In the summaries below, we have included references to section numbers of the indenture so that you can easily locate these provisions.

We are not required to issue future issues of senior indebtedness under the senior indenture described in this prospectus. We are free to use other indentures or documentation, containing provisions different from those described in this prospectus, in connection with future issues of other senior indebtedness not under this registration statement.

The senior debt securities will be represented either by global senior debt securities registered in the name of The Depository Trust Company (“DTC”), as depository (the “Depository”), or its nominee, or by securities in certificated form issued to the registered owners, as described in the applicable prospectus supplement. See the information under the heading “Book-Entry System” in this prospectus.

General

The senior debt securities will be issued in one or more new series under an indenture dated as of December 1, 2000 between us and Wells Fargo Bank, National Association, as trustee (the “Senior Debt Trustee”). This indenture, as previously supplemented by supplemental indentures and as may be supplemented by a new supplemental indenture for additional series of debt securities, is referred to in this prospectus as the “Senior Indenture.” As of December 31, 2020, there were ten series of senior debt securities in an aggregate principal amount of approximately $4.8 billion outstanding under the Senior Indenture.

The holders of the outstanding senior debt securities do not, and, unless the supplemental indenture that describes a particular series of senior debt securities provides otherwise with respect to that series, the holders of any senior debt securities offered by this prospectus will not, have the right to require us to repurchase the senior debt securities if we become involved in a highly leveraged or change in control transaction. The Senior Indenture does not have any provision that is designed specifically in response to highly leveraged or change in control transactions.

The senior debt securities will be our unsecured and unsubordinated obligations. The senior debt securities will rank on a parity in right of payment with all of our existing and future unsecured and unsubordinated indebtedness and will rank senior to any of our subordinated indebtedness. As of December 31, 2020, we had no junior subordinated debt outstanding and our aggregate unsecured and unsubordinated indebtedness was approximately $4.8 billion. The senior debt securities will be subordinated to any of our secured indebtedness, as to the assets securing such indebtedness. As of December 31, 2020, we had no secured indebtedness.

In addition, the senior debt securities will be effectively subordinated to all existing and future liabilities of our subsidiaries. We are a holding company and conduct business through our various subsidiaries. As a result, our cash flow and consequent ability to meet our debt obligations primarily depend on the earnings of our subsidiaries, and on dividends and other payments from our subsidiaries. Under certain circumstances, contractual and legal restrictions, as well as the financial condition and operating requirements of our subsidiaries, could limit our ability to obtain cash from our subsidiaries for the purpose of meeting debt service obligations, including the payment of principal and interest on the senior debt securities. Any rights to receive assets of any subsidiary upon its liquidation or reorganization and the consequent right of the holders of the senior debt securities to participate in those assets will be subject to the claims of that subsidiary’s creditors, including trade creditors, except to the extent that we are recognized as a creditor of that subsidiary, in which

2

case our claims would still be subordinate to any security interests in the assets of that subsidiary. As of December 31, 2020, our subsidiaries had approximately $16.3 billion of indebtedness and other liabilities outstanding.

The amount of securities that we may issue under the Senior Indenture is not limited. We are not required to issue all senior debt securities of one series at the same time and, unless we indicate otherwise in the applicable prospectus supplement, we may reopen a series for issuances of additional senior debt securities of that series without the consent of the holders of the senior debt securities of that series.

We may also sell hybrid or novel securities now existing or developed in the future that combine certain features of the senior debt securities and other securities described in this prospectus.

When we offer to sell a particular series of senior debt securities, we will describe the specific terms of that series in a prospectus supplement relating to that series, including the following terms:

• the title, aggregate principal amount and offering price of that series of senior debt securities;

• the interest rate or rates, or method of calculation of such rate or rates, on that series, and the date from which the interest will accrue;

• the dates on which interest will be payable;

• the record dates for payments of interest;

• the date on which the senior debt securities of that series will mature;

• any redemption terms;

• the period or periods within which, the price or prices at which and the terms and conditions upon which the senior debt securities of that series may be repaid, in whole or in part, at the option of the holder thereof;

• any changes to events of default or covenants; and

• other specific terms applicable to the senior debt securities of that series.

Any special U.S. federal income tax considerations applicable to senior debt securities sold at an original issue discount and any special U.S. federal income tax or other considerations applicable to any senior debt securities which are denominated in currencies other than U.S. dollars will be described in the prospectus supplement relating to that series of senior debt securities.

Unless we indicate otherwise in the applicable prospectus supplement, the senior debt securities will be denominated in U.S. dollars in minimum denominations of $1,000 and integral multiples thereof.

Registration, Transfer and Exchange

Senior debt securities of any series may be exchanged for other senior debt securities of the same series of any authorized denominations and of a like aggregate principal amount, series and stated maturity and having the same terms and original issue date or dates. (Section 2.6 of the Senior Indenture).

Unless we indicate otherwise in the applicable prospectus supplement, senior debt securities may be presented for registration of transfer (duly endorsed or accompanied by a duly executed written instrument of transfer), at the office of the Senior Debt Trustee maintained for that purpose with respect to any series of senior debt securities and referred to in the applicable prospectus supplement, without service charge and upon payment of any taxes and other governmental charges as described in the Senior Indenture. Any transfer or exchange will be effected if the senior debt securities are duly endorsed by, or accompanied by a written instrument or instruments of transfer in a form satisfactory to the Company and the Senior Debt Trustee and duly executed by the holder of the senior debt security as described in the Senior Indenture. (Section 2.6 of the Senior Indenture).

The Senior Debt Trustee will not be required to exchange or register a transfer of any senior debt securities of a series selected, called or being called for redemption except, in the case of any senior debt security to be

3

redeemed in part, the portion thereof not to be so redeemed. (Section 2.6 of the Senior Indenture). See the information under the heading “Book-Entry System” in this prospectus.

Payment and Paying Agents

Principal, interest and premium, if any, on senior debt securities issued in the form of global senior debt securities will be paid in the manner described below under the heading “Book-Entry System.” Unless we indicate otherwise in the applicable prospectus supplement, interest on senior debt securities that are in the form of certificated senior debt securities will be paid by check mailed to the holder at that person’s address as it appears in the register for the senior debt securities maintained by the Senior Debt Trustee; however, a holder of $10,000,000 or more senior debt securities having the same interest payment dates will be entitled to receive payments of interest by wire transfer to a bank within the continental United States if appropriate wire transfer instructions have been received by the Senior Debt Trustee on or prior to the applicable record date. (Section 2.12 of the Senior Indenture). Unless we indicate otherwise in the applicable prospectus supplement, the principal, interest at maturity and premium, if any, on senior debt securities in the form of certificated senior debt securities will be payable in immediately available funds at the office of the Senior Debt Trustee. (Section 2.12 of the Senior Indenture).

All monies paid by us to a paying agent for the payment of principal, interest or premium, if any, on any senior debt security which remain unclaimed at the end of two years after that principal, interest or premium has become due and payable will be repaid to us and the holder of that senior debt security will thereafter look only to us for payment of that principal, interest or premium. (Section 4.4 of the Senior Indenture).

Events of Default and Remedies

The following constitute events of default under the Senior Indenture:

• default in the payment of principal and premium, if any, on any security issued under the Senior Indenture when due and payable and continuance of that default for 5 days;

• default in the payment of interest on any security issued under the Senior Indenture when due and continuance of that default for 30 days;

• default in the performance or breach of our other covenants or warranties in the securities or in the Senior Indenture and the continuation of that default or breach for 90 days after written notice to us as provided in the Senior Indenture; and

• specified events of bankruptcy, insolvency or reorganization of our company.

(Section 7.1 of the Senior Indenture).

Acceleration of Maturity. If an event of default occurs and is continuing, either the Senior Debt Trustee or the holders of a majority in principal amount of the outstanding senior debt securities may declare the principal amount of all senior debt securities to be due and payable immediately. At any time after an acceleration of the securities has been declared, but before a judgment or decree of the immediate payment of the principal amount of the securities has been obtained, if we pay or deposit with the Senior Debt Trustee a sum sufficient to pay all matured installments of interest and the principal and any premium which has become due otherwise than by acceleration and all defaults have been cured or waived, then that payment or deposit will cause an automatic rescission and annulment of the acceleration of the securities. (Section 7.1 of the Senior Indenture).

Indemnification of Senior Debt Trustee. The Senior Debt Trustee generally will be under no obligation to exercise any of its rights or powers under the Senior Indenture at the request or direction of any of the holders unless such holders have offered reasonable security or indemnity to the Senior Debt Trustee. (Section 8.2 of the Senior Indenture).

Right to Direct Proceedings. The holders of a majority in principal amount of the outstanding securities generally will have the right to direct the time, method and place of conducting any proceeding for any remedy

4

available to the Senior Debt Trustee, or of exercising any trust or power conferred on the Senior Debt Trustee, relating to the securities. However, the Senior Debt Trustee may refuse to follow any direction that conflicts with law or the Senior Indenture or would expose the Senior Debt Trustee to personal liability or be unduly prejudicial to holders not joining in such proceeding. (Section 7.7 of the Senior Indenture).

Limitation on Rights to Institute Proceedings. No holder of the senior debt securities of a series will have any right to pursue a remedy under the Senior Indenture, unless:

• the holder has previously given the Senior Debt Trustee written notice of a continuing event of default on the series;

• the holders of at least a majority in principal amount of the outstanding securities affected by such event of default have made written request, and the holder or holders have offered indemnity satisfactory to the Senior Debt Trustee to pursue the remedy; and

• the Senior Debt Trustee has failed to comply with the request within 60 days after the request and offer.

(Section 7.4 of the Senior Indenture).

No Impairment of Right to Receive Payment. Notwithstanding any other provision of the Senior Indenture, the holder of any senior debt security will have the absolute and unconditional right to receive payment of the principal, premium, if any, and interest on that senior debt security when due, and to institute suit for enforcement of that payment. This right may not be impaired without the consent of the holder. (Section 7.4 of the Senior Indenture).

Notice of Default. The Senior Debt Trustee is required to give the holders notice of the occurrence of a default within 90 days of the default, unless the default is cured or waived. Except in the case of a payment default on the senior debt securities, or a default in the payment of any sinking or purchase fund installments, the Senior Debt Trustee may withhold the notice if its board of directors or trustees, executive committee, or a trust committee of directors or trustees or responsible officers determines in good faith that it is in the interest of holders to do so. (Section 7.8 of the Senior Indenture). We are required to deliver to the Senior Debt Trustee each year a certificate as to whether or not we are in compliance with the conditions and covenants under the Senior Indenture. (Section 5.5 of the Senior Indenture).

Modification

Unless we indicate otherwise in the applicable prospectus supplement, we and the Senior Debt Trustee may modify and amend the Senior Indenture from time to time.

We will not need the consent of the holders for the following types of amendments:

• curing any ambiguity, or curing, correcting or supplementing any defective or inconsistent provision or supplying an omission arising under the Senior Indenture;

• changing or eliminating any of the provisions of the Senior Indenture, provided that any such change or elimination is to become effective only when:

• there is no outstanding security created prior to the execution of the supplemental indenture that is entitled to receive the benefit of this provision; or

• this change or elimination is applicable only to securities issued after the date this change or elimination becomes effective;

• establishing the form of the securities or establishing or reflecting any terms of any security as provided in the Senior Indenture;

5

• evidencing our successor corporation and the assumption by our successor of our covenants in the Senior Indenture and in the securities;

• granting to or conferring upon the Senior Debt Trustee any additional rights, remedies, powers or authority for the benefit of the holders of the securities;

• permitting the Senior Debt Trustee to comply with any duties imposed upon it by law;

• specifying further the duties and responsibilities of the Senior Debt Trustee, any authenticating agent and any paying agent and defining further the relationships among the Senior Debt Trustee, authenticating agent and paying agent;

• adding to our covenants for the benefit of the holders of the securities or surrendering a right given to us in the Senior Indenture;

• adding security for the securities; or

• making any other change that is not prejudicial to the Senior Debt Trustee or the holders of the securities.

(Section 12.1 of the Senior Indenture).

We will need the consent of the holders of each outstanding security affected by a proposed amendment if the amendment would cause any of the following to occur:

• a change in the maturity date, reduction of the interest rate, or extension of the time of payment of interest, of any security;

• a reduction in the principal amount of any security or the premium payable on any security;

• a change in the currency of any payment of principal, premium or interest on any security;

• a change in date on which any security may be redeemed or repaid at the option of the holder;

• an impairment of the right of a holder to institute suit for the enforcement of any payment relating to any security;

• a reduction in the percentage of outstanding securities necessary to consent to the modification or amendment of the Senior Indenture; or

• a modification of these requirements or a reduction to less than a majority of the percentage of outstanding securities necessary to waive events of default.

(Section 12.2 of the Senior Indenture).

Amendments other than those described in the above two paragraphs will require the approval of a majority in principal amount of the outstanding securities.

Conversion Rights

Any supplemental indenture establishing a series of senior debt securities may provide for conversion rights. We will describe in the applicable prospectus supplement the particular terms and conditions, if any, on which senior debt securities may be convertible into other securities. These terms will include the conversion rate, the conversion period, provisions as to whether conversion will be mandatory or at our option or the option of the holder, events requiring an adjustment of the conversion rate and provisions affecting conversion in the event of the

6

redemption of the debt securities. If we issue convertible debt securities, we will need to supplement the indenture to add applicable provisions regarding conversion.

Defeasance and Discharge

We may be discharged from all obligations relating to the senior debt securities and the Senior Indenture (except for specified obligations such as obligations to register the transfer or exchange of securities, replace stolen, lost or mutilated securities and maintain paying agencies) if we irrevocably deposit with the Senior Debt Trustee, in trust for the benefit of holders of securities, money or U.S. government obligations (or any combination thereof) sufficient to make all payments of principal, premium and interest on the securities on the dates those payments are due. To discharge these obligations, we must deliver to the Senior Debt Trustee an opinion of counsel that the holders of the securities will not recognize income, gain or loss for federal income tax purposes as a result of such defeasance or discharge of the Senior Indenture. Upon any discharge of our obligations as described above, we will be deemed to have paid and discharged our entire indebtedness represented by the senior debt securities and our obligations under the senior debt securities. (Section 4.1 of the Senior Indenture).

Consolidation, Merger and Sale of Assets; No Financial Covenants

We will not consolidate with or merge into any other corporation or sell, or otherwise dispose all or substantially all of our assets unless the successor or transferee corporation assumes by supplemental indenture our obligations to pay the principal, interest and premium on all the securities and our obligation to perform every covenant of the Senior Indenture that we are to perform or observe, and we or the successor or transferee corporation, as applicable, are not immediately following such consolidation or merger, or sale, or disposition in default in the performance of any such covenant. Upon any consolidation or merger, or any sale, transfer or other disposition of all or substantially all of our assets, the successor or transferee corporation will succeed to, and be substituted for, and may exercise all of our rights and powers under the Senior Indenture with the same effect as if the successor corporation had been named as us in the Senior Indenture and we will be released from all obligations under the Senior Indenture. Regardless of whether a sale or transfer of assets might otherwise be considered a sale of all or substantially all of our assets, the Senior Indenture also specifically permits any sale, transfer or conveyance of our non-utility subsidiaries if, following such sale or transfer, the securities are rated by Standard & Poor’s Ratings Group and Moody’s Investors Service, Inc. at least as high as the ratings accorded the securities immediately prior to the sale, transfer or disposition. (Sections 11.1 and 11.2 of the Senior Indenture).

The Senior Indenture does not contain any financial or other similar restrictive covenants.

Resignation or Removal of Senior Debt Trustee

The Senior Debt Trustee may resign at any time by notifying us in writing and specifying the day that the resignation is to take effect. The resignation will not take effect, however, until the later of the appointment of a successor trustee and the day the resignation is to take effect. (Section 8.10 of the Senior Indenture).

The holders of a majority in principal amount of the outstanding securities may remove the Senior Debt Trustee at any time. In addition, so long as no event of default or event which, with the giving of notice or lapse of time or both, would become an event of default has occurred and is continuing, we may remove the Senior Debt Trustee upon notice to the holder of each security outstanding and written notice to the Senior Debt Trustee. (Section 8.10 of the Senior Indenture).

Governing Law

The Senior Indenture and the senior debt securities will be governed by, and will be construed in accordance with, the laws of the State of Minnesota.

7

Concerning the Senior Debt Trustee

Wells Fargo Bank, National Association is the Senior Debt Trustee. We maintain banking relationships with the Senior Debt Trustee in the ordinary course of business. The Senior Debt Trustee also acts as trustee for our junior subordinated debt securities and certain debt securities of our subsidiaries.

8

DESCRIPTION OF SUBORDINATED DEBT SECURITIES

We may issue subordinated debt securities (other than the junior subordinated debt securities (as defined below under “Description of Junior Subordinated Debt Securities” in this prospectus)), in one or more series, under one or more subordinated indentures. The description below contains summaries of selected provisions of the indenture under which the subordinated debt securities may be issued. These summaries are not complete. The form of subordinated indenture and the form of the supplemental indenture applicable to the subordinated debt securities have been filed as exhibits to the registration statement. You should read them for provisions that may be important to you. In the summaries below, we have included references to section numbers of the subordinated indenture so that you can easily locate these provisions.

We are not required to issue future issues of subordinated indebtedness under the subordinated indenture described in this prospectus. We are free to use other indentures or documentation, containing provisions different from those described in this prospectus, in connection with future issues of other subordinated indebtedness not under this registration statement.

The subordinated debt securities will be represented either by global subordinated debt securities registered in the name of the Depository or its nominee, or by securities in certificated form issued to the registered owners, as set forth in the applicable prospectus supplement. See the information under the heading “Book-Entry System” in this prospectus.

General

The subordinated debt securities will be issued in one or more new series under a subordinated indenture to be entered into between us and a trustee to be named therein, as trustee (the “Subordinated Trustee”). This subordinated indenture, as it may be supplemented by a supplemental indenture for each series of subordinated debt securities, is referred to in this prospectus as the “Subordinated Indenture.” As of December 31, 2020, we have no subordinated debt securities outstanding under the Subordinated Indenture.

The subordinated debt securities will be our unsecured obligations and will rank senior to any of our junior subordinated indebtedness and will rank junior in right of payment to our Senior Indebtedness, as described under the caption “— Subordination”. As of December 31, 2020, our outstanding Senior Indebtedness (as defined below) was approximately $4.8 billion.

In addition, the subordinated debt securities will be effectively subordinated to all existing and future liabilities of our subsidiaries, including trade creditors, debtholders, secured creditors, taxing authorities, guarantee holders and any preferred shareholders. We are a holding company and conduct business through our various subsidiaries. As a result, our cash flow and consequent ability to meet our debt obligations primarily depend on the earnings of our subsidiaries, and on dividends and other payments from our subsidiaries. Under certain circumstances, contractual and legal restrictions, as well as the financial condition and operating requirements of our subsidiaries, could limit our ability to obtain cash from our subsidiaries for the purpose of meeting debt service obligations, including the payment of principal and interest on the subordinated debt securities. Any rights to receive assets of any subsidiary upon its liquidation or reorganization and the consequent right of the holders of the subordinated debt securities to participate in those assets will be subject to the claims of that subsidiary’s creditors, including trade creditors, except to the extent that we are recognized as a creditor of that subsidiary, in which case our claims would still be subordinate to any security interests in the assets of that subsidiary. As of December 31, 2020, our subsidiaries had approximately $16.3 billion of indebtedness and other liabilities outstanding.

Unless the supplemental indenture that describes a particular series of subordinated debt securities provides otherwise with respect to that series, the holders of any subordinated debt securities offered by this prospectus will not have the right to require us to repurchase the subordinated debt securities if we become involved in a highly leveraged or change in control transaction. The Subordinated Indenture does not have any provision that is designed specifically in response to highly leveraged or change in control transactions.

9

The amount of subordinated debt securities that we may issue under the Subordinated Indenture is not limited. We are not required to issue all subordinated debt securities of one series at the same time and, unless we indicate otherwise in the applicable prospectus supplement, we may reopen a series for issuances of additional subordinated debt securities of that series without the consent of the holders of the subordinated debt securities of that series.

We may also sell hybrid or novel securities now existing or developed in the future that combine certain features of the subordinated debt securities and other securities described in this prospectus.

When we offer to sell a particular series of subordinated debt securities, we will describe the specific terms of that series in a prospectus supplement relating to that series, including the following terms:

• the title, aggregate principal amount and offering price of that series of subordinated debt securities;

• the interest rate or rates, or method of calculation of such rate or rates, on that series, and the date from which the interest will accrue;

• the dates on which interest will be payable;

• any rights that would allow us to defer or extend an interest payment date;

• the record dates for payments of interest;

• the date on which the subordinated debt securities of that series will mature;

• any redemption terms;

• the period or periods within which, the price or prices at which and the terms and conditions upon which the subordinated debt securities of that series may be repaid, in whole or in part, at the option of the holder thereof;

• any changes to events of default or covenants;

• any changes to subordination provisions; and

• other specific terms applicable to the subordinated debt securities of that series.

Any special U.S. federal income tax considerations applicable to subordinated debt securities sold at an original issue discount and any special U.S. federal income tax or other considerations applicable to any subordinated debt securities which are denominated in currencies other than U.S. dollars will be described in the prospectus supplement relating to that series of subordinated debt securities.

Unless we indicate otherwise in the applicable prospectus supplement, the subordinated debt securities will be denominated in U.S. dollars in minimum denominations of $1,000 and integral multiples thereof.

Subordination

Each series of subordinated debt securities will be subordinate and junior in right of payment, to the extent set forth in the Subordinated Indenture, to all Senior Indebtedness (as defined below). If:

• we make a payment or distribution of any of our assets to creditors upon our dissolution, winding-up, liquidation or reorganization, whether in bankruptcy, insolvency or otherwise;

• a default in the payment of principal or interest on any Senior Indebtedness has occurred and is continuing; or

10

• the maturity of any Senior Indebtedness has been accelerated because of a default on that Senior Indebtedness,

then the holders of Senior Indebtedness generally will have the right to receive payment, in the case of the first instance above, of all amounts due or to become due upon that Senior Indebtedness, and, in the case of the second and third instances, of all amounts due on that Senior Indebtedness, or we will make provision for those payments, before the holders of any subordinated debt securities have the right to receive any payments of principal or interest on their securities. (Sections 14.1 and 14.9 of the Subordinated Indenture).

Unless we indicate otherwise in the applicable prospectus supplement, “Senior Indebtedness” includes the senior debt securities and means, with respect to any series of subordinated debt securities, the principal, premium, interest and any other payment in respect of any of the following, whether outstanding on the date of execution of the Subordinated Indenture or thereafter incurred, other than obligations expressly on a parity with the subordinated debt securities or junior to the subordinated debt securities:

• all of our current and future indebtedness for borrowed or purchase money whether or not evidenced by bonds, debentures, notes or other similar written instruments;

• our obligations under synthetic leases, finance leases and capitalized leases;

• our obligations for reimbursement under letters of credit, banker’s acceptances, security purchase facilities or similar facilities issued for our account;

• any of our other indebtedness or obligations with respect to derivative contracts, including commodity contracts, interest rate, commodity and currency swap agreements, forward contracts and other similar agreements or arrangements designed to protect against fluctuations in commodity prices, currency exchange or interest rates; and

• all indebtedness of others of the kinds described in the preceding categories which we have assumed or guaranteed.

Senior Indebtedness will not include trade accounts payable, accrued liabilities arising in the ordinary course of business, indebtedness to our subsidiaries or any indebtedness which is by its terms junior to or on parity with the subordinated debt securities, including the junior subordinated indebtedness issued under the Junior Subordinated Indenture. (Section 1.3 of the Subordinated Indenture.)

Senior Indebtedness will be entitled to the benefits of the subordination provisions in the Subordinated Indenture irrespective of the amendment, modification or waiver of any term of the Senior Indebtedness. We may not amend the Subordinated Indenture to change the subordination of any outstanding subordinated debt securities without the consent of each holder of subordinated debt securities that such amendment would adversely affect. (Sections 12.2 and 14.7 of the Subordinated Indenture.)

The Subordinated Indenture does not limit the amount of subordinated debt securities that we may issue.

Registration, Transfer and Exchange

Subordinated debt securities of any series may be exchanged for other subordinated debt securities of the same series of any authorized denominations and of a like aggregate principal amount, series and stated maturity and having the same terms and original issue date or dates. (Section 2.6 of the Subordinated Indenture).

Unless we indicate otherwise in the applicable prospectus supplement, subordinated debt securities may be presented for registration of transfer (duly endorsed or accompanied by a duly executed written instrument of transfer), at the office of the Subordinated Debt Trustee maintained for that purpose with respect to any series of subordinated debt securities and referred to in the applicable prospectus supplement, without service charge and

11

upon payment of any taxes and other governmental charges as described in the Subordinated Indenture. Any transfer or exchange will be effected if the subordinated debt securities are duly endorsed by, or accompanied by a written instrument or instruments of transfer in a form satisfactory to the Company and the Subordinated Debt Trustee and duly executed by the holder of the subordinated debt security as described in the Subordinated Indenture. (Section 2.6 of the Subordinated Indenture).

The Subordinated Debt Trustee will not be required to exchange or register a transfer of any subordinated debt securities of a series selected, called or being called for redemption except, in the case of any subordinated debt security to be redeemed in part, the portion thereof not to be so redeemed. (Section 2.6 of the Subordinated Indenture). See the information under the heading “Book-Entry System” in this prospectus.

Payment and Paying Agents

Principal, interest and premium, if any, on subordinated debt securities issued in the form of global subordinated debt securities will be paid in the manner described below under the heading “Book-Entry System.” Unless we indicate otherwise in the applicable prospectus supplement, interest on subordinated debt securities that are in the form of certificated subordinated debt securities will be paid by check mailed to the holder at that person’s address as it appears in the register for the subordinated debt securities maintained by the Subordinated Debt Trustee; however, a holder of $10,000,000 or more subordinated debt securities having the same interest payment dates will be entitled to receive payments of interest by wire transfer to a bank within the continental United States if appropriate wire transfer instructions have been received by the Subordinated Debt Trustee on or prior to the applicable record date. (Section 2.12 of the Subordinated Indenture). Unless we indicate otherwise in the applicable prospectus supplement, the principal, interest at maturity and premium, if any, on subordinated debt securities in the form of certificated subordinated debt securities will be payable in immediately available funds at the office of the Subordinated Debt Trustee. (Section 2.12 of the Subordinated Indenture).

All monies paid by us to a paying agent for the payment of principal, interest or premium, if any, on any subordinated debt security which remain unclaimed at the end of two years after that principal, interest or premium has become due and payable will be repaid to us and the holder of that subordinated debt security will thereafter look only to us for payment of that principal, interest or premium. (Section 4.4 of the Subordinated Indenture).

Events of Default and Remedies

Unless we provide otherwise in a prospectus supplement, the following will constitute events of default under the Subordinated Indenture with respect to the subordinated debt securities of any series:

• default in the payment of principal and premium, if any, on any security of such series when due and payable and continuance of that default for 5 days;

• default in the payment of interest on any security of such series when due and continuance of that default for 30 days (subject, if applicable, to the right to optionally defer interest payments);

• default in the performance or breach of our other covenants or warranties in the securities of such series or in the Subordinated Indenture (other than a covenant or agreement that has been expressly included in the Subordinated Indenture for the benefit of one or more series of subordinated debt securities other than such series) and the continuation of that default or breach for 90 days after written notice to us as provided in the Subordinated Indenture; and

• specified events of bankruptcy, insolvency or reorganization of our company.

(Section 7.1 of the Subordinated Indenture).

Acceleration of Maturity. If an event of default occurs and is continuing with respect to a series of subordinated debt securities, either the Subordinated Debt Trustee or the holders of at least 25% in principal

12

amount of the outstanding securities of that series may declare the principal amount of all securities of that series to be due and payable immediately. At any time after an acceleration of a series of securities has been declared, but before a judgment or decree of the immediate payment of the principal amount of those securities has been obtained, if:

• holders of a majority in aggregate principal amount of the securities of that series rescind in writing the acceleration; and

• we pay or deposit with the Subordinated Debt Trustee a sum sufficient to pay all matured installments of interest with respect to that series of securities and the principal and any premium which has become due with respect to that series of securities otherwise than by acceleration and all defaults with respect to that series of securities have been cured or waived, then that holders’ rescission and the payment or deposit will cause an automatic rescission and annulment of the acceleration of the securities of that series. (Section 7.1 of the Subordinated Indenture).

Indemnification of Subordinated Debt Trustee. The Subordinated Debt Trustee generally will be under no obligation to exercise any of its rights or powers under the Subordinated Indenture at the request or direction of any of the holders unless such holders have offered reasonable security or indemnity to the Subordinated Debt Trustee. (Section 8.2 of the Subordinated Indenture).

Right to Direct Proceedings. The holders of a majority in principal amount of the outstanding securities of a series generally will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Subordinated Debt Trustee, or of exercising any trust or power conferred on the Subordinated Debt Trustee, relating to the securities of that series. Notwithstanding, the Subordinated Debt Trustee may refuse to follow any direction that conflicts with law or the Subordinated Indenture or would expose the Subordinated Debt Trustee to personal liability or be unduly prejudicial to holders not joining in such proceeding. (Section 7.7 of the Subordinated Indenture).

Limitation on Rights to Institute Proceedings. No holder of the subordinated debt securities of a series will have any right to pursue a remedy under the Subordinated Indenture, unless:

• the holder has previously given the Subordinated Debt Trustee written notice of a continuing event of default on the series;

• the holders of at least a majority in principal amount of the outstanding securities of all series affected by such event of default, considered as one class, have made written request, and the holder or holders have offered indemnity satisfactory to the Subordinated Debt Trustee to pursue the remedy; and

• the Subordinated Debt Trustee has failed to comply with the request within 60 days after the request and offer.

(Section 7.4 of the Subordinated Indenture).

No Impairment of Right to Receive Payment. Notwithstanding any other provision of the Subordinated Indenture, the holder of any subordinated debt security will have the absolute and unconditional right to receive payment of the principal, premium, if any, and interest on that subordinated debt security when due and payable, and to institute suit for enforcement of that payment. This right may not be impaired without the consent of the holder. (Section 7.4 of the Subordinated Indenture).

Notice of Default. The Subordinated Debt Trustee is required to give the holders of a series of securities notice of the occurrence of a default within 90 days of the default with respect to that series, unless the default is cured or waived. Except in the case of a payment default on the subordinated debt securities, or a default in the payment of any sinking or purchase fund installments, the Subordinated Debt Trustee may withhold the notice if its board of directors or trustees, executive committee, or a trust committee of directors or trustees or responsible officers determines in good faith that it is in the interest of holders of the series of affected securities to do so.

13

(Section 7.8 of the Subordinated Indenture). We are required to deliver to the Subordinated Debt Trustee each year a certificate as to whether or not we are in compliance with the conditions and covenants under the Subordinated Indenture. (Section 5.5 of the Subordinated Indenture).

Conversion Rights

A series of subordinated debt securities may provide for conversion rights. We will describe in the applicable prospectus supplement the particular terms and conditions, if any, on which subordinated debt securities may be convertible into other securities. These terms will include the conversion rate, the conversion period, provisions as to whether conversion will be mandatory or at our option or the option of the holder, events requiring an adjustment of the conversion rate and provisions affecting conversion in the event of the redemption of the debt securities.

Defeasance and Discharge

We may be discharged from all obligations relating to the subordinated debt securities and the Subordinated Indenture (except for specified obligations such as obligations to register the transfer or exchange of securities, replace stolen, lost or mutilated securities and maintain paying agencies) if we irrevocably deposit with the Subordinated Debt Trustee, in trust for the benefit of holders of securities, money or U.S. government obligations (or any combination thereof) sufficient to make all payments of principal, premium and interest on the securities on the dates those payments are due. To discharge these obligations, we must deliver to the Subordinated Debt Trustee an opinion of counsel to the effect that we have received from, or there has been published by, the Internal Revenue Service a ruling or similar pronouncement by the Internal Revenue Service or that there has been a change in law, in either case to the effect that the holders of the securities will not recognize income, gain or loss for federal income tax purposes as a result of such defeasance or discharge of the Subordinated Indenture, and holders will be subject to tax in the same manner, in the same amounts and same time as would have been the case absent such defeasance. Upon any discharge of our obligations as described above, we will be deemed to have paid and discharged our entire indebtedness represented by the subordinated debt securities and our obligations under the subordinated debt securities. (Section 4.1 of the Subordinated Indenture).

Modification

Unless we indicate otherwise in the applicable prospectus supplement, we and the Subordinated Debt Trustee may modify and amend the Subordinated Indenture from time to time.

We will not need the consent of the holders for the following types of amendments:

• curing any ambiguity, or curing, correcting or supplementing any defective or inconsistent provision or supplying an omission arising under the Subordinated Indenture;

• changing or eliminating any of the provisions of the Subordinated Indenture, provided that any such change or elimination is to become effective only when:

• there is no outstanding security created prior to the execution of the supplemental indenture that is entitled to receive the benefit of this provision; or

• this change or elimination is applicable only to securities issued after the date this change or elimination becomes effective;

• establishing the form of the securities or establishing or reflecting any terms of any security as provided in the Subordinated Indenture;

• evidencing our successor corporation and the assumption by our successor of our covenants in the Subordinated Indenture and in the securities;

• granting to or conferring upon the Subordinated Debt Trustee any additional rights, remedies, powers or authority for the benefit of the holders of the securities;

14

• permitting the Subordinated Debt Trustee to comply with any duties imposed upon it by law;

• specifying further the duties and responsibilities of the Subordinated Debt Trustee, any authenticating agent and any paying agent and defining further the relationships among the Subordinated Debt Trustee, authenticating agent and paying agent;

• adding to our covenants for the benefit of the holders of the securities, surrendering a right given to us in the Subordinated Indenture or adding any event of default with respect to one or more series of securities;

• facilitating defeasance and discharge of any series of the securities, provided that such action shall not adversely affect the interest of any holder;

• adding security for the securities; or

• making any other change that is not prejudicial to the Subordinated Debt Trustee or the holders of the securities.

(Section 12.1 of the Subordinated Indenture).

We will need the consent of the holders of each outstanding security affected by a proposed amendment if the amendment would cause any of the following to occur:

• a change in the maturity date, reduction of the interest rate, or extension of the time of payment of interest, of any security;

• a reduction in the principal amount of any security or the premium payable on any security;

• a change in the currency of any payment of principal, premium or interest on any security;

• a change in date on which any security may be redeemed or repaid at the option of the holder;

• an impairment of the right of a holder to institute suit for the enforcement of any payment relating to any security;

• a reduction in the percentage of outstanding securities necessary to consent to the modification or amendment of the Subordinated Indenture;

• a modification of these requirements or a reduction to less than a majority of the percentage of outstanding securities necessary to waive events of default; or

• a modification of the subordination provisions in a manner adverse to such holders.

(Section 12.2 of the Subordinated Indenture).

Amendments other than those described in the above two paragraphs will require the approval of a majority in principal amount of the outstanding securities of all series, provided that if there are securities of more than one series outstanding and if a proposed amendment would directly affect the rights of holders of securities of one or more, but less than all, of such series, then the approval of a majority in principal amount of the outstanding securities of all series so directly affected, considered as one class, will be required.

Consolidation, Merger and Sale of Assets; No Financial Covenants

We will not consolidate with or merge into any other corporation or sell, or otherwise dispose all or substantially all of our assets unless the successor or transferee corporation assumes by supplemental indenture our obligations to pay the principal, interest and premium on all the securities and our obligation to perform every covenant of the Subordinated Indenture that we are to perform or observe, and we or the successor or transferee corporation, as applicable, are not immediately following such consolidation or merger, or sale, or disposition in default in the performance of any such covenant. Upon any consolidation or merger, or any sale,

15

transfer or other disposition of all or substantially all of our assets, the successor or transferee corporation will succeed to, and be substituted for, and may exercise all of our rights and powers under the Subordinated Indenture with the same effect as if the successor corporation had been named as us in the Subordinated Indenture and we will be released from all obligations under the Subordinated Indenture. Regardless of whether a sale or transfer of assets might otherwise be considered a sale of all or substantially all of our assets, the Subordinated Indenture also specifically permits any sale, transfer or conveyance of our non-utility subsidiaries if, following such sale or transfer, the securities are rated by Standard & Poor’s Ratings Group and Moody’s Investors Service, Inc. at least as high as the ratings accorded the securities immediately prior to the sale, transfer or disposition. (Sections 11.1 and 11.2 of the Subordinated Indenture).

The Subordinated Indenture does not contain any financial or other similar restrictive covenants.

Resignation or Removal of Subordinated Debt Trustee

The Subordinated Debt Trustee may resign with respect to securities of any series at any time by notifying us in writing and specifying the day that the resignation is to take effect. The resignation will not take effect, however, until the later of the appointment of a successor trustee and the day the resignation is to take effect. (Section 8.10 of the Subordinated Indenture).

The holders of a majority in principal amount of the outstanding securities of any series may remove the Subordinated Debt Trustee as trustee of that series of securities at any time. In addition, so long as no event of default or event which, with the giving of notice or lapse of time or both, would become an event of default has occurred and is continuing with respect to securities of any series, we may remove the Subordinated Debt Trustee with respect to securities of that series upon notice to the holder of each security of that series outstanding and written notice to the Subordinated Debt Trustee. (Section 8.10 of the Subordinated Indenture).

Governing Law

The Subordinated Indenture and the subordinated debt securities will be governed by, and will be construed in accordance with, the laws of the State of Minnesota. (Section 15.4 of the Subordinated Indenture).

The Subordinated Debt Trustee

The Subordinated Indenture requires that the Subordinated Trustee be a corporation organized and doing business under the laws of the United States or any State thereof or of the District of Columbia (or a corporation or other person permitted to act as trustee by the Commission), subject to supervision or examination by such bodies and authorized under such laws to exercise corporate trust powers and having a combined capital and surplus of at least $150,000,000. If at any time the Subordinated Trustee shall cease to be eligible to serve as trustee under the Subordinated Indenture, the Subordinated Trustee shall resign immediately and a new trustee will be appointed as provided in the Subordinated Indenture.

DESCRIPTION OF JUNIOR SUBORDINATED DEBT SECURITIES

The description below contains summaries of selected provisions of the indenture, including supplemental indentures, under which the junior subordinated debt securities may be issued (referred to herein as “junior subordinated indenture”). These summaries are not complete. The junior subordinated indenture and the form of the supplemental indenture applicable to the junior subordinated debt securities have been filed as exhibits to the registration statement. You should read them for provisions that may be important to you. In the summaries below, we have included references to section numbers of the junior subordinated indenture so that you can easily locate these provisions.

We are not required to issue future issues of junior subordinated indebtedness under the junior subordinated indenture described in this prospectus. We are free to use other indentures or documentation, containing provisions different from those described in this prospectus, in connection with future issues of other junior subordinated indebtedness not under this registration statement.

The junior subordinated debt securities will be represented either by global junior subordinated debt securities registered in the name of the Depository or its nominee, or by securities in certificated form issued to the registered owners, as set forth in the applicable prospectus supplement. See the information under the heading “Book-Entry System” in this prospectus.

General

The junior subordinated debt securities will be issued in one or more new series under an indenture dated as of January 1, 2008 between us and Wells Fargo Bank, National Association, as trustee (the “Junior Subordinated Debt Trustee”). This junior subordinated indenture, as it may be supplemented by a supplemental indenture for each series of junior subordinated debt securities, is referred to in this prospectus as the “Junior Subordinated Indenture.” As of December 31, 2020, we have no junior subordinated debt outstanding under the Junior Subordinated Indenture.

The junior subordinated debt securities will be our unsecured obligations and will rank on a parity in right of payment with all of our future junior subordinated indebtedness and junior in right of payment to our Senior Ranking Indebtedness, as described under the caption “—Subordination”. As of December 31, 2020, our outstanding Senior Ranking Indebtedness (as defined below) was approximately $4.8 billion.

In addition, the junior subordinated debt securities will be effectively subordinated to all existing and future liabilities of our subsidiaries, including trade creditors, debtholders, secured creditors, taxing authorities, guarantee holders and any preferred shareholders. We are a holding company and conduct business through our various subsidiaries. As a result, our cash flow and consequent ability to meet our debt obligations primarily depend on the earnings of our subsidiaries, and on dividends and other payments from our subsidiaries. Under certain circumstances, contractual and legal restrictions, as well as the financial condition and operating requirements of our subsidiaries, could limit our ability to obtain cash from our subsidiaries for the purpose of meeting debt service obligations, including the payment of principal and interest on the junior subordinated debt securities. Any rights to receive assets of any subsidiary upon its liquidation or reorganization and the consequent right of the holders of the junior subordinated debt securities to participate in those assets will be subject to the claims of that subsidiary’s creditors, including trade creditors, except to the extent that we are recognized as a creditor of that subsidiary, in which case our claims would still be subordinate to any security interests in the assets of that subsidiary. As of December 31, 2020, our subsidiaries had approximately $16.3 billion of indebtedness and other liabilities outstanding.

Unless the supplemental indenture that describes a particular series of junior subordinated debt securities provides otherwise with respect to that series, the holders of any junior subordinated debt securities offered by this prospectus will not have the right to require us to repurchase the junior subordinated debt securities if we

17

become involved in a highly leveraged or change in control transaction. The Junior Subordinated Indenture does not have any provision that is designed specifically in response to highly leveraged or change in control transactions.

The amount of junior subordinated debt securities that we may issue under the Junior Subordinated Indenture is not limited. We are not required to issue all junior subordinated debt securities of one series at the same time and, unless we indicate otherwise in the applicable prospectus supplement, we may reopen a series for issuances of additional junior subordinated debt securities of that series without the consent of the holders of the junior subordinated debt securities of that series.

We may also sell hybrid or novel securities now existing or developed in the future that combine certain features of the junior subordinated debt securities and other securities described in this prospectus.

When we offer to sell a particular series of junior subordinated debt securities, we will describe the specific terms of that series in a prospectus supplement relating to that series, including the following terms:

• the title, aggregate principal amount and offering price of that series of junior subordinated debt securities;

• the interest rate or rates, or method of calculation of such rate or rates, on that series, and the date from which the interest will accrue;

• the dates on which interest will be payable;

• any rights that would allow us to defer or extend an interest payment date;

• the record dates for payments of interest;

• the date on which the junior subordinated debt securities of that series will mature;

• any redemption terms;

• the period or periods within which, the price or prices at which and the terms and conditions upon which the junior subordinated debt securities of that series may be repaid, in whole or in part, at the option of the holder thereof;

• any changes to events of default or covenants;

• any changes to subordination provisions; and

• other specific terms applicable to the junior subordinated debt securities of that series.

Any special U.S. federal income tax considerations applicable to junior subordinated debt securities sold at an original issue discount and any special U.S. federal income tax or other considerations applicable to any junior subordinated debt securities which are denominated in currencies other than U.S. dollars will be described in the prospectus supplement relating to that series of junior subordinated debt securities.

Unless we indicate otherwise in the applicable prospectus supplement, the junior subordinated debt securities will be denominated in U.S. dollars in minimum denominations of $1,000 and integral multiples thereof.

Subordination

Each series of junior subordinated debt securities will be subordinate and junior in right of payment, to the extent set forth in the Junior Subordinated Indenture, to all Senior Ranking Indebtedness (as defined below). If:

• we make a payment or distribution of any of our assets to creditors upon our dissolution, winding-up, liquidation or reorganization, whether in bankruptcy, insolvency or otherwise;

• a default in the payment of principal or interest on any Senior Ranking Indebtedness has occurred and is continuing; or

18

• the maturity of any Senior Ranking Indebtedness has been accelerated because of a default on that Senior Ranking Indebtedness,

then the holders of Senior Ranking Indebtedness generally will have the right to receive payment, in the case of the first instance above, of all amounts due or to become due upon that Senior Ranking Indebtedness, and, in the case of the second and third instances, of all amounts due on that Senior Ranking Indebtedness, or we will make provision for those payments, before the holders of any junior subordinated debt securities have the right to receive any payments of principal or interest on their securities. (Sections 14.1 and 14.9 of the Junior Subordinated Indenture).

“Senior Ranking Indebtedness” means, with respect to any series of junior subordinated debt securities, the principal, premium, interest and any other payment in respect of any of the following, whether outstanding on the date of execution of the Junior Subordinated Indenture or thereafter incurred, other than obligations expressly on a parity with or junior to the junior subordinated debt securities:

• all of our current and future indebtedness for borrowed or purchase money whether or not evidenced by bonds, debentures, notes or other similar written instruments, including indebtedness issued under our Senior Indenture or Subordinated Indenture described above;

• our obligations under synthetic leases, finance leases and capitalized leases;

• our obligations for reimbursement under letters of credit, banker’s acceptances, security purchase facilities or similar facilities issued for our account;

• any of our other indebtedness or obligations with respect to derivative contracts, including commodity contracts, interest rate, commodity and currency swap agreements, forward contracts and other similar agreements or arrangements designed to protect against fluctuations in commodity prices, currency exchange or interest rates; and

• all indebtedness of others of the kinds described in the preceding categories which we have assumed or guaranteed.

Senior Ranking Indebtedness will not include trade accounts payable, accrued liabilities arising in the ordinary course of business, indebtedness to our subsidiaries or any indebtedness which is by its terms junior to or on parity with the junior subordinated debt securities. (Section 1.3 of the Junior Subordinated Indenture.)

Senior Ranking Indebtedness will be entitled to the benefits of the subordination provisions in the Junior Subordinated Indenture irrespective of the amendment, modification or waiver of any term of the Senior Ranking Indebtedness. We may not amend the Junior Subordinated Indenture to change the subordination of any outstanding junior subordinated debt securities without the consent of each holder of junior subordinated debt securities that such amendment would adversely affect. (Sections 12.2 and 14.7 of the Junior Subordinated Indenture.)

The Junior Subordinated Indenture does not limit the amount of junior subordinated debt securities that we may issue.

Registration, Transfer and Exchange

Junior subordinated debt securities of any series may be exchanged for other junior subordinated debt securities of the same series of any authorized denominations and of a like aggregate principal amount, series and stated maturity and having the same terms and original issue date or dates. (Section 2.6 of the Junior Subordinated Indenture).

Unless we indicate otherwise in the applicable prospectus supplement, junior subordinated debt securities may be presented for registration of transfer (duly endorsed or accompanied by a duly executed written

19

instrument of transfer), at the office of the Junior Subordinated Debt Trustee maintained for that purpose with respect to any series of junior subordinated debt securities and referred to in the applicable prospectus supplement, without service charge and upon payment of any taxes and other governmental charges as described in the Junior Subordinated Indenture. Any transfer or exchange will be effected if the junior subordinated debt securities are duly endorsed by, or accompanied by a written instrument or instruments of transfer in a form satisfactory to the Company and the Junior Subordinated Debt Trustee and duly executed by the holder of the junior subordinated debt security as described in the Junior Subordinated Indenture. (Section 2.6 of the Junior Subordinated Indenture).

The Junior Subordinated Debt Trustee will not be required to exchange or register a transfer of any junior subordinated debt securities of a series selected, called or being called for redemption except, in the case of any junior subordinated debt security to be redeemed in part, the portion thereof not to be so redeemed. (Section 2.6 of the Junior Subordinated Indenture). See the information under the heading “Book-Entry System” in this prospectus.

Payment and Paying Agents

Principal, interest and premium, if any, on junior subordinated debt securities issued in the form of global junior subordinated debt securities will be paid in the manner described below under the heading “Book-Entry System.” Unless we indicate otherwise in the applicable prospectus supplement, interest on junior subordinated debt securities that are in the form of certificated junior subordinated debt securities will be paid by check mailed to the holder at that person’s address as it appears in the register for the junior subordinated debt securities maintained by the Junior Subordinated Debt Trustee; however, a holder of $10,000,000 or more junior subordinated debt securities having the same interest payment dates will be entitled to receive payments of interest by wire transfer to a bank within the continental United States if appropriate wire transfer instructions have been received by the Junior Subordinated Debt Trustee on or prior to the applicable record date. (Section 2.12 of the Junior Subordinated Indenture). Unless we indicate otherwise in the applicable prospectus supplement, the principal, interest at maturity and premium, if any, on junior subordinated debt securities in the form of certificated junior subordinated debt securities will be payable in immediately available funds at the office of the Junior Subordinated Debt Trustee. (Section 2.12 of the Junior Subordinated Indenture).

All monies paid by us to a paying agent for the payment of principal, interest or premium, if any, on any junior subordinated debt security which remain unclaimed at the end of two years after that principal, interest or premium has become due and payable will be repaid to us and the holder of that junior subordinated debt security will thereafter look only to us for payment of that principal, interest or premium. (Section 4.4 of the Junior Subordinated Indenture).

Events of Default and Remedies

Unless we provide otherwise in a prospectus supplement, the following will constitute events of default under the Junior Subordinated Indenture with respect to the junior subordinated debt securities of any series:

• default in the payment of principal and premium, if any, on any security of such series when due and payable and continuance of that default for 5 days;

• default in the payment of interest on any security of such series when due and continuance of that default for 30 days (subject, if applicable, to the right to optionally defer interest payments);

• default in the performance or breach of our other covenants or warranties in the securities of such series or in the Junior Subordinated Indenture (other than a covenant or agreement that has been expressly included in the Junior Subordinated Indenture for the benefit of one or more series of junior subordinated debt securities other than such series) and the continuation of that default or breach for 90 days after written notice to us as provided in the Junior Subordinated Indenture; and

20

• specified events of bankruptcy, insolvency or reorganization of our company.

(Section 7.1 of the Junior Subordinated Indenture).

Acceleration of Maturity. If an event of default occurs and is continuing with respect to a series of junior subordinated debt securities, either the Junior Subordinated Debt Trustee or the holders of at least 25% in principal amount of the outstanding securities of that series may declare the principal amount of all securities of that series to be due and payable immediately. At any time after an acceleration of a series of securities has been declared, but before a judgment or decree of the immediate payment of the principal amount of those securities has been obtained, if:

• holders of a majority in aggregate principal amount of the securities of that series rescind in writing the acceleration; and

• we pay or deposit with the Junior Subordinated Debt Trustee a sum sufficient to pay all matured installments of interest with respect to that series of securities and the principal and any premium which has become due with respect to that series of securities otherwise than by acceleration and all defaults with respect to that series of securities have been cured or waived,

then that holders’ rescission and the payment or deposit will cause an automatic rescission and annulment of the acceleration of the securities of that series. (Section 7.1 of the Junior Subordinated Indenture).

Indemnification of Junior Subordinated Debt Trustee. The Junior Subordinated Debt Trustee generally will be under no obligation to exercise any of its rights or powers under the Junior Subordinated Indenture at the request or direction of any of the holders unless such holders have offered reasonable security or indemnity to the Junior Subordinated Debt Trustee. (Section 8.2 of the Junior Subordinated Indenture).

Right to Direct Proceedings. The holders of a majority in principal amount of the outstanding securities of a series generally will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Junior Subordinated Debt Trustee, or of exercising any trust or power conferred on the Junior Subordinated Debt Trustee, relating to the securities of that series. Notwithstanding, the Junior Subordinated Debt Trustee may refuse to follow any direction that conflicts with law or the Junior Subordinated Indenture or would expose the Junior Subordinated Debt Trustee to personal liability or be unduly prejudicial to holders not joining in such proceeding. (Section 7.7 of the Junior Subordinated Indenture).

Limitation on Rights to Institute Proceedings. No holder of the junior subordinated debt securities of a series will have any right to pursue a remedy under the Junior Subordinated Indenture, unless:

• the holder has previously given the Junior Subordinated Debt Trustee written notice of a continuing event of default on the series;

• the holders of at least a majority in principal amount of the outstanding securities of all series affected by such event of default, considered as one class, have made written request, and the holder or holders have offered indemnity satisfactory to the Junior Subordinated Debt Trustee to pursue the remedy; and

• the Junior Subordinated Debt Trustee has failed to comply with the request within 60 days after the request and offer.

(Section 7.4 of the Junior Subordinated Indenture).

No Impairment of Right to Receive Payment. Notwithstanding any other provision of the Junior Subordinated Indenture, the holder of any junior subordinated debt security will have the absolute and unconditional right to receive payment of the principal, premium, if any, and interest on that junior subordinated debt security when due and payable, and to institute suit for enforcement of that payment. This right may not be impaired without the consent of the holder. (Section 7.4 of the Junior Subordinated Indenture).

21

Notice of Default. The Junior Subordinated Debt Trustee is required to give the holders of a series of securities notice of the occurrence of a default within 90 days of the default with respect to that series, unless the default is cured or waived. Except in the case of a payment default on the junior subordinated debt securities, or a default in the payment of any sinking or purchase fund installments, the Junior Subordinated Debt Trustee may withhold the notice if its board of directors or trustees, executive committee, or a trust committee of directors or trustees or responsible officers determines in good faith that it is in the interest of holders of the series of affected securities to do so. (Section 7.8 of the Junior Subordinated Indenture). We are required to deliver to the Junior Subordinated Debt Trustee each year a certificate as to whether or not we are in compliance with the conditions and covenants under the Junior Subordinated Indenture. (Section 5.5 of the Junior Subordinated Indenture).

Conversion Rights

Any supplemental indenture establishing a series of junior subordinated debt securities may provide for conversion rights. We will describe in the applicable prospectus supplement the particular terms and conditions, if any, on which junior subordinated debt securities may be convertible into other securities. These terms will include the conversion rate, the conversion period, provisions as to whether conversion will be mandatory or at our option or the option of the holder, events requiring an adjustment of the conversion rate and provisions affecting conversion in the event of the redemption of the debt securities. If we issue convertible debt securities, we will need to supplement the indenture to add applicable provisions regarding conversion.

Defeasance and Discharge

We may be discharged from all obligations relating to the junior subordinated debt securities and the Junior Subordinated Indenture (except for specified obligations such as obligations to register the transfer or exchange of securities, replace stolen, lost or mutilated securities and maintain paying agencies) if we irrevocably deposit with the Junior Subordinated Debt Trustee, in trust for the benefit of holders of securities, money or U.S. government obligations (or any combination thereof) sufficient to make all payments of principal, premium and interest on the securities on the dates those payments are due. To discharge these obligations, we must deliver to the Junior Subordinated Debt Trustee an opinion of counsel to the effect that we have received from, or there has been published by, the Internal Revenue Service a ruling or similar pronouncement by the Internal Revenue Service or that there has been a change in law, in either case to the effect that the holders of the securities will not recognize income, gain or loss for federal income tax purposes as a result of such defeasance or discharge of the Junior Subordinated Indenture, and holders will be subject to tax in the same manner, in the same amounts and same time as would have been the case absent such defeasance. Upon any discharge of our obligations as described above, we will be deemed to have paid and discharged our entire indebtedness represented by the junior subordinated debt securities and our obligations under the junior subordinated debt securities. (Section 4.1 of the Junior Subordinated Indenture).

Modification

Unless we indicate otherwise in the applicable prospectus supplement, we and the Junior Subordinated Debt Trustee may modify and amend the Junior Subordinated Indenture from time to time.

We will not need the consent of the holders for the following types of amendments:

• curing any ambiguity, or curing, correcting or supplementing any defective or inconsistent provision or supplying an omission arising under the Junior Subordinated Indenture;

• changing or eliminating any of the provisions of the Junior Subordinated Indenture, provided that any such change or elimination is to become effective only when:

• there is no outstanding security created prior to the execution of the supplemental indenture that is entitled to receive the benefit of this provision; or

22

• this change or elimination is applicable only to securities issued after the date this change or elimination becomes effective;

• establishing the form of the securities or establishing or reflecting any terms of any security as provided in the Junior Subordinated Indenture;

• evidencing our successor corporation and the assumption by our successor of our covenants in the Junior Subordinated Indenture and in the securities;

• granting to or conferring upon the Junior Subordinated Debt Trustee any additional rights, remedies, powers or authority for the benefit of the holders of the securities;

• permitting the Junior Subordinated Debt Trustee to comply with any duties imposed upon it by law;

• specifying further the duties and responsibilities of the Junior Subordinated Debt Trustee, any authenticating agent and any paying agent and defining further the relationships among the Junior Subordinated Debt Trustee, authenticating agent and paying agent;

• adding to our covenants for the benefit of the holders of the securities, surrendering a right given to us in the Junior Subordinated Indenture or adding any event of default with respect to one or more series of securities;

• facilitating defeasance and discharge of any series of the securities, provided that such action shall not adversely affect the interest of any holder;

• adding security for the securities; or

• making any other change that is not prejudicial to the Junior Subordinated Debt Trustee or the holders of the securities.

(Section 12.1 of the Junior Subordinated Indenture).

We will need the consent of the holders of each outstanding security affected by a proposed amendment if the amendment would cause any of the following to occur:

• a change in the maturity date, reduction of the interest rate, or extension of the time of payment of interest, of any security;

• a reduction in the principal amount of any security or the premium payable on any security;

• a change in the currency of any payment of principal, premium or interest on any security;

• a change in date on which any security may be redeemed or repaid at the option of the holder;

• an impairment of the right of a holder to institute suit for the enforcement of any payment relating to any security;

• a reduction in the percentage of outstanding securities necessary to consent to the modification or amendment of the Junior Subordinated Indenture;

• a modification of these requirements or a reduction to less than a majority of the percentage of outstanding securities necessary to waive events of default; or

• a modification of the subordination provisions in a manner adverse to such holders.

(Section 12.2 of the Junior Subordinated Indenture).

Amendments other than those described in the above two paragraphs will require the approval of a majority in principal amount of the outstanding securities of all series, provided that if there are securities of more than one series outstanding and if a proposed amendment would directly affect the rights of holders of securities of one or more, but less than all, of such series, then the approval of a majority in principal amount of the outstanding securities of all series so directly affected, considered as one class, will be required.

23

Consolidation, Merger and Sale of Assets; No Financial Covenants

We will not consolidate with or merge into any other corporation or sell, or otherwise dispose all or substantially all of our assets unless the successor or transferee corporation assumes by supplemental indenture our obligations to pay the principal, interest and premium on all the securities and our obligation to perform every covenant of the Junior Subordinated Indenture that we are to perform or observe, and we or the successor or transferee corporation, as applicable, are not immediately following such consolidation or merger, or sale, or disposition in default in the performance of any such covenant. Upon any consolidation or merger, or any sale, transfer or other disposition of all or substantially all of our assets, the successor or transferee corporation will succeed to, and be substituted for, and may exercise all of our rights and powers under the Junior Subordinated Indenture with the same effect as if the successor corporation had been named as us in the Junior Subordinated Indenture and we will be released from all obligations under the Junior Subordinated Indenture. Regardless of whether a sale or transfer of assets might otherwise be considered a sale of all or substantially all of our assets, the Junior Subordinated Indenture also specifically permits any sale, transfer or conveyance of our non-utility subsidiaries if, following such sale or transfer, the securities are rated by Standard & Poor’s Ratings Group and Moody’s Investors Service, Inc. at least as high as the ratings accorded the securities immediately prior to the sale, transfer or disposition. (Sections 11.1 and 11.2 of the Junior Subordinated Indenture).

The Junior Subordinated Indenture does not contain any financial or other similar restrictive covenants.

Resignation or Removal of Junior Subordinated Debt Trustee

The Junior Subordinated Debt Trustee may resign with respect to securities of any series at any time by notifying us in writing and specifying the day that the resignation is to take effect. The resignation will not take effect, however, until the later of the appointment of a successor trustee and the day the resignation is to take effect. (Section 8.10 of the Junior Subordinated Indenture).

The holders of a majority in principal amount of the outstanding securities of any series may remove the Junior Subordinated Debt Trustee as trustee of that series of securities at any time. In addition, so long as no event of default or event which, with the giving of notice or lapse of time or both, would become an event of default has occurred and is continuing with respect to securities of any series, we may remove the Junior Subordinated Debt Trustee with respect to securities of that series upon notice to the holder of each security of that series outstanding and written notice to the Junior Subordinated Debt Trustee. (Section 8.10 of the Junior Subordinated Indenture).

Governing Law

The Junior Subordinated Indenture and the junior subordinated debt securities will be governed by, and will be construed in accordance with, the laws of the State of Minnesota. (Section 15.4 of the Junior Subordinated Indenture).

Concerning the Junior Subordinated Debt Trustee

Wells Fargo Bank, National Association is the Junior Subordinated Debt Trustee. We maintain banking relationships with the Junior Subordinated Debt Trustee in the ordinary course of business. The Junior Subordinated Debt Trustee also acts as trustee for our senior debt securities and certain debt securities of our subsidiaries.

DESCRIPTION OF COMMON STOCK

The following summary description sets forth some of the general terms and provisions of the common stock. This summary is not complete. For a more detailed description of the common stock, you should refer to the provisions of our Amended and Restated Articles of Incorporation (“Articles”) and Bylaws, as amended (“Bylaws”). The Articles and the Bylaws have been filed as exhibits to the registration statement. You should read them for provisions that may be important to you.

General

Our capital stock consists of two classes: common stock, par value $2.50 per share (1,000,000,000 shares currently authorized of which 537,648,833 shares were outstanding as of February 11, 2021); and preferred stock, par value $100.00 per share (7,000,000 shares authorized, of which no shares were outstanding as of February 11, 2021).

Dividend Rights

Before we can pay any dividends on our common stock, the holders of our preferred stock, if any, are entitled to receive dividends at the respective rates provided for in the terms of the shares of any outstanding series.

Because we are a holding company and conduct all of our operations through our subsidiaries, our cash flow and ability to pay dividends is dependent on the earnings and cash flows of our subsidiaries and the distribution or other payment of those earnings to us in the form of dividends, or in the form of repayments of loans or advances to us. Some of our subsidiaries may have restrictions on their ability to pay dividends including covenants under their borrowing arrangements and mortgage indentures, and possibly also restrictions imposed by their regulators and by statute. See “Management’s Discussion and Analysis of Financial Conditions and Results of Operations — Common Stock Dividends” and Notes to Consolidated Financial Statements in our most recent Annual Report on Form 10-K for a discussion of factors affecting our payment of dividends including limitations imposed by statute.

Voting Rights

The holders of our common stock are entitled to one vote for each share held on all matters submitted to a vote of our shareholders. Cumulative voting in the election of directors is not permitted.

Preferred Stock

Our board of directors is authorized, to the fullest extent permitted by law, to establish out of our authorized capital stock up to 7,000,000 shares of preferred stock, which may be issued in one or more classes or series, having such dividend rights and times of payment, redemption prices, liquidation prices or preferences as to assets in voluntary liquidation, and other relative rights and preferences as our board of directors shall determine. As of February 11, 2021, no shares of preferred stock were outstanding. The terms of any preferred stock issued by the Company could have the effect of delaying or preventing a change in control without further action by our shareholders. The issuance of shares of preferred stock with voting and conversion rights may adversely affect the voting power of the holders of our common stock.

Change of Control

Our Bylaws and the Minnesota Business Corporation Act, as amended (the “MBCA”), contain provisions that could discourage, delay, prevent or make more difficult a change of control of our company. including, but not limited to, those summarized below.

Bylaw Provisions. Under our Bylaws, our shareholders must provide us advance notice of the introduction by them of director nominations or other business at annual meetings of our shareholders. For a shareholder to properly bring a proposal before an annual meeting, the shareholder must comply with the requirements under the federal proxy rules and deliver a written notice to our Corporate Secretary, or mail and be received at our principal executive office, not less than 90 days before the first anniversary date of the preceding year’s annual meeting. If,

25

however, the date of the annual meeting is more than 30 days before or 60 days after such anniversary date, the notice must be so delivered or so mailed and received not less than 90 days before the annual meeting or, if later, within ten days after the first public announcement of the date of the annual meeting. The required notice from a shareholder must contain a description of the nominee or the other business being introduced, the reasons for introducing such business, the name and address of each shareholder supporting the nomination or proposal and such other information as required under our Bylaws and the federal proxy rules.

A shareholder, or a group of up to 20 shareholders, owning 3% or more of the Company’s outstanding common stock continuously for at least three years can nominate and include in the Company’s proxy materials director-nominees constituting up to two individuals or 20% of the board (whichever is greater), provided that the shareholder(s) and the director-nominee(s) satisfy the requirements specified in the Bylaws. To be timely, the proposal must be delivered to our Corporate Secretary, or mailed and received at our principal executive office, not less than 120 days and not more than 150 days prior to the first anniversary of the date that the Company distributed its proxy statement to shareholders for the previous year’s annual meeting of shareholders. If, however, the date of the annual meeting of shareholders is more than 30 days before or after such anniversary date, the Notice of Proxy Access Nomination shall be timely if so delivered or so mailed and received not less than 90 days before the annual meeting or, if later, within ten days after the first public announcement of the date of the annual meeting. The required notice from such a shareholder must contain such information as required under our Bylaws and the federal proxy rules.

Except to the extent otherwise required by law, the adjournment of an annual meeting of shareholders will not commence a new time period for the giving of a shareholder’s notice as required above.

MBCA. Section 302A.433 of the MBCA provides that special meetings of the Company’s shareholders may be called by our chairman, chief executive officer, chief financial officer, two or more directors, or shareholders holding 10% or more of the voting power of all shares entitled to vote, except that a special meeting called by shareholders for the purpose of considering any action to directly or indirectly facilitate or effect a business combination, including any action to change or otherwise affect the composition of our board of directors for that purpose, must be called by 25% or more of the voting power of all shares entitled to vote. Section 302A.441 of the MBCA also provides that action may be taken by shareholders without a meeting only by unanimous written consent.

Section 302A.671 of the MBCA applies to potential acquirers of 20% or more of our voting shares. Section 302A.671 provides in substance that shares acquired by such acquirer will not have any voting rights unless the voting rights are either:

• approved by (i) a majority of the voting power of all of our shares entitled to vote including all shares held by the acquirer and (ii) a majority of the voting power of all of our shares entitled to vote excluding all interested shares; or

• acquired in a transaction that (i) is pursuant to a tender offer or exchange offer for all of our voting shares, (ii) results in the acquirer becoming the owner of at least a majority of our outstanding voting shares, and (iii) has been approved by a committee of disinterested directors.

In general, shares acquired in the absence of such approval are denied voting rights and are redeemable at their then fair market value by the Company within 30 days after the acquiring person has failed to give a timely information statement to the Company or the date the shareholders voted not to grant voting rights to the acquiring person’s shares.

Section 302A.673 of the MBCA generally prohibits public Minnesota corporations, including us, from engaging in any business combination with a person or entity owning, directly or indirectly, 10% or more of our voting shares for a period of four years after the date of the transaction in which such person or entity became a 10% shareholder unless the business combination or the acquisition resulting in 10% ownership was approved by a committee of disinterested directors prior to the date such person or entity became a 10% shareholder.

26

Section 302A.675 of the MBCA provides in substance that a person or entity making a takeover offer for us is prohibited from acquiring any additional shares of our company within two years following the last purchase of shares pursuant to the offer with respect to that class unless (i) the acquisition is approved by a committee of disinterested directors before the purchase of any shares by the offeror pursuant to the offer or (ii) our shareholders are afforded, at the time of the acquisition, a reasonable opportunity to dispose of their shares to the offeror upon substantially equivalent terms as those provided in the earlier takeover offer.

Liquidation Rights

If we were to liquidate, subject to the terms of any outstanding series of preferred stock, the holders of our common stock are entitled to receive pro rata our assets legally available for distribution to shareholders.

Preemptive and Subscription Rights

No holder of our capital stock has the preemptive right to purchase or subscribe for any additional shares of our capital stock.

Concerning the Transfer Agent

Our common stock is listed on the Nasdaq Stock Market LLC. EQ Shareowner Services is the Transfer Agent and Registrar for the common stock.

27

DESCRIPTION OF PREFERRED STOCK

Our board of directors is authorized, to the fullest extent permitted by law, to establish out of our authorized capital stock up to 7,000,000 shares of preferred stock, which may be issued in one or more classes or series, having such dividend rights and times of payment, redemption prices, liquidation prices or preferences, and the other rights and preferences as our board of directors shall determine at the time of issuance. As of February 11, 2021, no shares of preferred stock were outstanding.

The issuance of our preferred stock, while potentially providing us with flexibility in connection with possible acquisitions and other corporate purposes, could have the effect of making it more difficult for a third party to acquire, or delay or deter a third party from attempting to acquire, a majority of our outstanding voting stock.

The rights, preferences, privileges and restrictions of the preferred stock of each series will be fixed by resolution of the board of directors. To the extent appropriate, we will include in a prospectus supplement the terms relating to any series of preferred stock being offered thereby. These terms will include some or all of the following, as applicable:

• the title of the series and the number of shares in the series;

• the price at which the preferred stock will be offered;

• the dividend rate or rates or method of calculating the rates, the dates on which and the place or places where the dividends will be payable, whether the dividends will be cumulative or noncumulative and, if cumulative, the dates from which dividends on the preferred stock being offered will cumulate;

• the voting rights, if any, of the holders of shares of the preferred stock being offered;

• the provisions for a sinking fund, if any, and the provisions for redemption, if applicable, of the preferred stock being offered;

• the liquidation preference per share;

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

• any date of maturity of the preferred stock;

• any listing of the preferred stock being offered on any securities exchange;

• whether interests in the shares of the series will be represented by depositary shares;

• a discussion of any material U.S. federal income tax considerations applicable to the preferred stock being offered;

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

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

• any or all other preferences and relative, participating, operational or other special rights or qualifications, limitations or restrictions of the series.

The MBCA provides that the holders of preferred stock have the right to vote separately as a class on any proposal involving changes in the rights or preferences of holders of such preferred stock. This right is in addition to any voting rights that may be provided for in the applicable resolution creating such preferred stock.

28

DESCRIPTION OF DEPOSITARY SHARES

We may offer depositary shares (either separately or together with other securities) representing fractional interests in our preferred stock of any series. The following description sets forth certain general terms and provisions of the depositary shares to which any prospectus supplement may relate. The particular terms of the depositary shares to which any prospectus supplement may relate and the extent, if any, to which the general terms and provisions may apply to the depositary shares so offered will be described in the applicable prospectus supplement. To the extent that any particular terms of the depositary shares, deposit agreements and depositary receipts described in a prospectus supplement differ from any of the terms described below, then the terms described below will be deemed to have been superseded by that prospectus supplement. We encourage you to read the applicable deposit agreement and depositary receipts for additional information before you decide whether to purchase any of our depositary shares.

In connection with the issuance of any depositary shares, we will enter into a deposit agreement with a bank or trust company, as depositary, which will be named in the applicable prospectus supplement. Depositary shares will be evidenced by depositary receipts issued pursuant to the related deposit agreement. Immediately following our issuance of the security related to the depositary shares, we will deposit the shares of our preferred stock with the relevant depositary and will cause the depositary to issue, on our behalf, the related depositary receipts. Subject to the terms of the deposit agreement, each owner of a depositary receipt will be entitled, in proportion to the fractional interest in the share of preferred stock represented by the related depositary share, to all the rights, preferences and privileges of, and will be subject to all of the limitations and restrictions on, the preferred stock represented by the depositary receipt (including, if applicable, dividend, voting, conversion, exchange, redemption, sinking fund, subscription and liquidation rights). To the extent appropriate, the applicable prospectus supplement will describe the specific terms of the depositary shares offered thereby. The terms of any offered depositary shares will be described in a supplement to this prospectus.

DESCRIPTION OF WARRANTS

We may issue warrants to purchase debt securities, common stock, preferred stock, depositary shares, or any combination thereof, with or without the payment of separate consideration therefor (including by means of a dividend or similar distribution to holders of our outstanding securities). We may issue warrants independently or together with any other securities offered by a prospectus supplement. Warrants may be attached to or separate from such securities and may or may not be transferable. Each series of warrants will be issued under a separate warrant agreement we will enter into with a warrant agent specified in the applicable prospectus supplement. The warrant agent will act solely as our agent in connection with the warrants of a particular series and will not assume any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants. In connection with any warrants, we may enter into a standby underwriting agreement with one or more underwriters pursuant to which the underwriters will agree to purchase any securities underlying such warrants that remain unpurchased upon the expiration of such warrants. To the extent appropriate, the applicable prospectus supplement will describe the specific terms of the warrants offered thereby.

DESCRIPTION OF RIGHTS

We may issue subscription rights to purchase shares of our common stock or preferred stock. These subscription rights may be issued independently or together with any other security offered hereby and may or may not be transferable by the shareholder receiving the subscription rights in such offering. In connection with any offering of subscription rights, we may enter into a standby arrangement with one or more underwriters or other investors pursuant to which the underwriters or other investors may be required to purchase any securities remaining unsubscribed for after such offering. To the extent appropriate, the applicable prospectus supplement will describe the specific terms of the rights offered thereby.

29

DESCRIPTION OF PURCHASE CONTRACTS

We may issue purchase contracts, including contracts obligating holders to purchase from us, and for us to sell to holders, a specific or varying number of debt securities, shares of our common stock or preferred stock, depositary shares, warrants, rights or other property or any combination of the above, at a future date or dates. Alternatively, the purchase contracts may obligate us to purchase from holders, and obligate holders to sell to us, a specific or varying number of debt securities, shares of our common stock or preferred stock, depositary shares, warrants, rights or other property. The price of such debt securities, shares of our common stock or preferred stock, depositary shares, warrants, rights or other property may be fixed at the time the purchase contracts are issued or may be determined by reference to a specific formula described in the purchase contracts. We may issue purchase contracts separately or as a part of units each consisting of a purchase contract and one or more of our other securities described in this prospectus or debt obligations of third parties, such as U.S. Treasury securities, securing the holder’s obligations under the purchase contract. The purchase contracts may require us to make periodic payments to holders or vice versa and the payments may be unsecured or pre-funded on some basis. The purchase contracts may require holders to secure the holder’s obligations in a specified manner that we will file with the SEC in connection with a public offering relating to the purchase contracts. To the extent appropriate, the applicable prospectus supplement will describe the specific terms of the purchase contracts offered thereby.

DESCRIPTION OF UNITS

We may issue units comprising one or more securities described in this prospectus in any combination. Units may also include debt obligations of third parties, such as U.S. Treasury securities. Each unit may be issued so that the holder of the unit also is the holder of each security included in the unit. Thus, the unit may have the rights and obligations of a holder of each included security. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately at any time or at any time before a specified date. To the extent appropriate, the applicable prospectus supplement will describe the specific terms of the units offered thereby.

30

BOOK-ENTRY SYSTEM

Unless otherwise specified in the applicable prospectus supplement, each series of securities offered by this prospectus will be issued as fully-registered global securities representing all or part of that series of securities. This means that we will not issue certificates for that series of securities to the holders. Instead, a global security representing that series of securities will be deposited with, or on behalf of, DTC or its successor, as the depository. The global securities will be registered at the request of DTC in the name of Cede & Co., DTC’s nominee, or such other name as may be requested by an authorized representative of DTC.

DTC will keep an electronic record of its participants (for example, your broker) whose clients have purchased securities represented by a global security. Unless a global security is exchanged in whole or in part for a certificated security, a global security may not be transferred, except that DTC, its nominees and successors may transfer a global security as a whole to one another.

Beneficial interests in global securities will be shown on, and transfers of interests will be made only through, records maintained by DTC and its participants. The laws of some jurisdictions require that some purchasers take physical delivery of securities in definitive form. These laws may impair the ability to transfer beneficial interests in a global security.

We will make payments of principal, interest, if any, and premium, if any, to DTC or its nominee. We, the applicable trustee and any paying agent will treat DTC or its nominee as the owner of the global security for all purposes, including any notices and voting. Accordingly, neither we nor any trustee nor any paying agent will have any direct responsibility or liability to pay amounts due on a global security to owners of beneficial interests in a global security.

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 System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds securities that its participants, (“direct participants”) deposit with DTC. DTC also facilitates the post-trade settlement among direct participants of sales and other securities transactions in deposited securities through electronic computerized book-entry transfers and pledges between direct participants’ accounts. This eliminates the need for physical movement of securities certificates. Direct participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. DTC is a wholly owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies and clearing corporations that clear through or maintain a custodial relationship with a direct participant either directly or indirectly (“indirect participant”). Direct participants and indirect participants are referred to collectively as “participants.” The DTC Rules applicable to its participants are on file with the SEC.

Purchases of global securities under the DTC system must be made by or through direct participants, which will receive a credit for the securities on DTC’s records. The ownership interest of each actual purchaser of each security (“beneficial owner”) is in turn to be recorded on the direct and indirect participants’ records. Beneficial owners will not receive written confirmation from DTC of their purchase. Beneficial owners are, however, expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the direct or indirect participant through which the beneficial owner entered into the transaction. Transfers of ownership interests in the global securities are to be accomplished by entries made on the books of direct and indirect participants acting on behalf of beneficial owners. Beneficial owners will not receive certificates representing their ownership interests in the global securities, except in the event that use of the book-entry system for the global securities is discontinued.

31

To facilitate subsequent transfers, all securities deposited by direct participants with DTC are registered in the name of Cede & Co. or such other name as may be requested by an authorized representative of DTC. The deposit of securities with DTC and their registration in the name of Cede & Co. or such other nominee do not effect any change in beneficial ownership. DTC has no knowledge of the actual beneficial owners of the securities. DTC’s records reflect only the identity of the direct participants to whose accounts such securities are credited, which may or may not be the beneficial owners. The direct and indirect participants remain responsible for keeping account of their holdings on behalf of their customers.

Conveyance of notices and other communications by DTC to direct participants, by direct participants to indirect participants and by direct participants and indirect participants to beneficial owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

If a particular series of securities is redeemable at our option or at the option of the holder, redemption notices will be sent to DTC. If less than all of the securities of a series are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each direct participant in such series to be redeemed. Redemption proceeds, distributions, and dividend payments on global securities will be made to Cede & Co. or such other nominee as may be requested by an authorized representative of DTC. Upon DTC’s receipt of funds and corresponding detail information from us, any trustee or any paying agent, DTC’s practice is to credit direct participants’ accounts in accordance with the holdings information shown on DTC’s records on the payment date. Payments by participants to beneficial owners of securities will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in “street name.” Payments will be the responsibility of such participant and not of DTC nor its nominee, any trustee, any paying agent or us, subject to any statutory or regulatory requirements. Payment of redemption proceeds, distributions, and dividend payments to Cede & Co. or such other nominee as may be requested by an authorized representative of DTC is the responsibility of us, the applicable trustee or the applicable paying agent, disbursement of such payments to direct participants will be the responsibility of DTC, and disbursement of such payments to the beneficial owners will be the responsibility of direct and indirect participants.

Neither DTC nor Cede & Co. or any other DTC nominee will consent or vote with respect to global securities unless authorized by a direct participant in accordance with DTC’s procedures. Under its usual procedures, DTC mails an omnibus proxy to us as soon as possible after the record date. The omnibus proxy assigns Cede & Co.’s consenting or voting rights to those direct participants to whose accounts the securities are credited on the record date as identified in a listing attached to the omnibus proxy.

Global securities will be exchangeable for corresponding certificated securities registered in the name of persons other than DTC or its nominee if (1) DTC (a) notifies us that it is unwilling or unable to continue as depository for any of the global securities or (b) at any time ceases to be a clearing agency registered under the Exchange Act, (2) an event of default occurs and is continuing with respect to the applicable series of securities or (3) we execute and deliver to the applicable trustee an order that the global securities will be so exchangeable.

The information in this section concerning DTC and DTC’s book-entry system has been obtained from DTC, and we and any underwriters, dealers or agents are not responsible for the accuracy of the information or for the performance by DTC of its obligations under the rules and procedures governing its operations or otherwise.

Any underwriters, dealers or agents of any securities may be direct participants of DTC.

32

PLAN OF DISTRIBUTION

We may sell the offered securities (a) through agents; (b) through underwriters or dealers; (c) directly to one or more purchasers; or (d) through a combination of any of these methods of sale. We will identify the specific plan of distribution, including any underwriters, dealers, agents or direct purchasers and their compensation in a prospectus supplement.

LEGAL OPINIONS

Unless otherwise indicated in the applicable prospectus supplement, legal opinions relating to the validity of the securities being offered by this prospectus will be rendered by our counsel, Amy L. Schneider, Minneapolis, Minnesota. Unless otherwise indicated in the applicable prospectus supplement, certain other legal matters will be passed upon for us by Jones Day, Chicago, Illinois. Unless otherwise indicated in the applicable supplement, certain legal matters will be passed upon for the underwriters, dealers or agents named in the prospectus supplement by Hunton Andrews Kurth LLP, New York, New York. Amy L. Schneider is our Vice President, Corporate Secretary and Securities and is the beneficial owner of less than 1% of our common stock.
