Positive
  • Registered capacity of $4.0 billion provides Duke Energy substantial flexibility to offer Notes over time
  • Demand maturity allows investors to redeem on demand (subject to procedures and timing)
  • Daily accrual and monthly compounding/reinvestment supports automatic growth of invested principal
  • Multiple convenient investment and redemption channels (checks, ACH, wire, payroll, Social Security, online)
Negative
  • Notes are unsecured and unrated, relying solely on Duke Energy Corporation's creditworthiness
  • Structurally subordinated to subsidiary debt; subsidiaries held ~$57.8 billion of indebtedness as of June 30, 2025
  • No secondary market and not FDIC-insured, making investments non-transferable and potentially illiquid in practice
  • Interest rate set by internal committee (not market-determined) and may vary by investor, creating governance and transparency concerns
  • Significant consolidated indebtedness disclosed (~$86.4 billion total including short-term) increasing creditor competition for cash flows

Insights

TL;DR: Debt-like product offers liquidity and yield variability but increases unsecured funding and depends on Duke Energy's credit and committee-set rates.

The PremierNotes provide Duke Energy a flexible demand funding channel with a registered capacity of $4.0 billion and a live outstanding cap of $2.0 billion. Interest is floating and set weekly by an internal committee, with daily accrual and monthly reinvestment, features attractive to investors seeking convenience and liquidity. However, the Notes are unsecured, unrated, not FDIC-insured and structurally subordinated to subsidiary creditors, meaning repayment depends on Duke Energy's consolidated financial condition and cash flows from subsidiaries. The prospectus discloses substantial consolidated debt balances which are relevant to funding risk assessments.

TL;DR: Governance and conflict-of-interest risks arise from committee-set rates and indemnification provisions favoring company officers.

The Duke Energy PremierNotes Committee, composed of company officers and employees, has broad discretion to set interest rates and modify plan terms. Committee members owe duties to Duke Energy and are indemnified except for bad faith, creating potential conflicts between issuer decisions and noteholder interests. The plan permits unilateral redemptions, investor eligibility decisions and limits on transfers, concentrating control with the issuer and its committee rather than independent trustees or market mechanisms.

IMPORTANT INFORMATION
An investment in the Notes involves risks. Prospective investors should carefully review the risk factors, as well as the other information, contained or incorporated by reference in this prospectus. You should consult your own financial and legal advisers as to the risks involved in an investment in the Notes and whether an investment is suitable for you.
All of the money you invest will be used to purchase Notes for you. All interest earned on your Notes will be reinvested monthly in additional Notes for your investment. All investments in the Notes are investments in unsecured debt obligations of Duke Energy Corporation. Only our assets are available to pay the principal and interest on the Notes. We do not maintain reserves for our obligations under the Notes and the Notes are not subject to any sinking fund. The Notes are unsecured and are not obligations of or guaranteed, endorsed or insured by any of our subsidiaries, The Northern Trust Company, which acts as the agent bank for the Notes, the Trustee or any other company. It is possible for you to lose some or all of your investment, including accrued interest, if we are unable to pay our debts, become bankrupt or seek creditor protection.
The Notes are not a money market fund, which is typically a diversified fund consisting of short-term debt securities of many issuers. The Notes are not subject to the requirements of the Investment Company Act of 1940 (including those regarding diversification and quality of investments for money market funds) or the Employee Retirement Income Security Act of 1974, as amended. The Notes are not equivalent to a deposit or other bank account and are not subject to the protection of Federal Deposit Insurance Corporation regulation or insurance or any other insurance. The Notes are not transferable, assignable or negotiable, they are not listed on any securities exchange, and there is no secondary market for the Notes. As a result, there is no public market valuation for the Notes.
The interest rate paid on investments in the Notes may not provide a basis for comparison with bank deposits or money market funds, which may use a different method of calculating yield, or other investments which pay a fixed yield for a stated period of time. The interest rate also does not necessarily bear any relation to the risks associated with or changes in our creditworthiness, credit rating or financial condition and may not compensate you for any increase in credit risk of investment in the Notes.

DUKE ENERGY PREMIERNOTES
Key risk factors to consider before investing include:

An investment in the Notes does not create a bank account or depositor relationship between you and Duke Energy or The Northern Trust Company, as the agent bank.

The Notes are not equivalent to a deposit or other bank account and are not subject to the protection of Federal Deposit Insurance Corporation (FDIC) regulation or insurance or any other insurance.

All of the money you invest will be used to purchase Notes for you. All interest earned on your Notes will be reinvested monthly in additional Notes for your investment. The Notes are not a money market fund, which is typically a diversified fund consisting of short-term debt of many issuers. The Notes are not subject to regulation under the Investment Company Act of 1940, as amended. Consequently, you will not have the benefit of federal laws and regulations designed to help maintain liquidity and a stable share price and set standards for credit quality, diversification and for maturity of individual securities and the overall portfolio.

The Notes are not subject to the requirements of the Employee Retirement Income Security Act of 1974, as amended.

The interest rate paid on investments in the Notes may not provide a basis for comparison with bank deposits or money market funds, which may use a different method of calculating yield, or other investments which pay a fixed yield for a stated period of time. The interest rate also does not necessarily bear any relation to the risks associated with or changes in our creditworthiness, credit rating or financial condition and may not compensate you for any increase in credit risk of investment in Notes.

Although you may redeem your investment in the Notes at any time in whole or in part, in the manner explained in this prospectus, you are not able to transfer your investment in the Notes to someone else. The Notes are not listed on any securities exchange, and no secondary market for the Notes currently exists nor will one develop in the future. Consequently, there is no public market valuation of the Notes to assist you in evaluating the Notes or the yield earned.

The Notes are unsecured debt obligations of Duke Energy Corporation. Only the assets of Duke Energy Corporation are available to pay the principal and interest on the Notes.

Duke Energy Corporation is a holding company, and we operate our businesses through our subsidiaries. Thus, our ability to meet our obligations under the Notes is dependent on the earnings and cash flows of those subsidiaries and the ability of those subsidiaries to pay dividends or to advance or repay funds to Duke Energy. In addition, the rights that Duke Energy and its creditors would have to participate in the assets of any such subsidiary upon the subsidiary’s liquidation or recapitalization will be subject to the prior claims of the subsidiary’s creditors. Certain subsidiaries of Duke Energy have incurred substantial amounts of debt in the operation and expansion of their businesses, and Duke Energy anticipates that certain of its subsidiaries will do so in the future.

Holders of Notes will generally have a junior position to claims of creditors of our subsidiaries, including trade creditors, debt holders, secured creditors, taxing authorities, guarantee holders and any holders of preferred stock. In addition to trade debt, certain of our operating subsidiaries have ongoing corporate debt programs used to finance their business activities. As of June 30, 2025, on a consolidated basis (including securities due within one year), we had approximately $86.4 billion of outstanding debt, of which approximately $57.8 billion was subsidiary debt. Approximately $650 million of such subsidiary debt was guaranteed by Duke Energy as of June 30, 2025.

The Notes are not guaranteed, endorsed or insured by any of our subsidiaries or any financial institution or government entity. Duke Energy does not maintain reserves for its obligations under the Notes. There is a risk that Duke Energy will be unable to meet interest payments or repay principal on the Notes. You may lose all or part of your investment, including accrued interest, if Duke Energy is unable to pay its debts, enters bankruptcy or seeks protection from its creditors.

You will not be able to exchange your Notes for any other securities of Duke Energy.

exceeds the maximum amount as determined by the Duke Energy PremierNotes Committee. In such event, you will be notified if your Notes will be redeemed and you will be permitted 30 days within which to make such investments or make such redemptions, as the case may be, to restore the investment balance within the minimum and maximum amounts. In addition, we may also redeem, at any time at our option, the Notes of any investor who is not or is no longer eligible to invest in the Notes, who has abused or misused the investment or redemption provisions applicable to the Notes or whose investments are otherwise inconsistent with the objectives of the Duke Energy PremierNotes Plan, in each case as we determine in our sole judgment and discretion. In the event that we determine to redeem a particular investor’s Notes for any of the reasons specified in the preceding sentence, we will notify the investor of our intention to redeem in full the Notes on the third business day following the date of our notice. Further, we may redeem the entire amount of, or any portion of, all of the outstanding Notes. Any such partial redemption of outstanding Notes will be effected by lot or pro rata or by any other method that is deemed fair and appropriate by the agent bank. We generally will give you 30-days’ prior written notice if the Notes are to be redeemed in whole or in part. In each of the redemption transactions described above, a redemption check will be sent to the investor in an amount equal to the principal amount of the redeemed Notes, including accrued and unpaid interest and less any applicable fees.
Fees
There are no maintenance fees with respect to your investment in the Notes, nor are there charges for your redemption checks (both initial and additional) or for effecting any Check Redemptions. You may, however, be charged a fee by your commercial bank or financial institution if you make an investment or receive a redemption amount by wire transfer. You may also incur a charge in obtaining any applicable signature guarantee.

We will only furnish information to you by telephone if you have specified the name, address, Notes investment number, and additional investment information of the registered owner of the Notes.
Taxes
The following is a summary of the U.S. Federal income tax consequences to you if you invest in the Notes. The discussion addresses only the income tax consequences to you if you are an individual and are a citizen of the United States for Federal income tax purposes. You should consult your own tax adviser concerning the application of United States Federal income tax laws, as well as the laws of any state, local or foreign taxing jurisdictions, to your situation.
The Notes are not qualified under Section 401(a) of the Internal Revenue Code, as amended. All interest credited to your Notes in any taxable year is reportable by you as taxable income for Federal income tax purposes. Early in each year the agent bank will provide to you the full amount reportable as taxable income for the previous year. The agent bank also will file tax information returns as required by law. Backup withholding may apply to you if you fail to comply with applicable tax identification requirements. Interest credited to the Notes also may be subject to state and local income taxes.
Duke Energy PremierNotes Committee
The Duke Energy PremierNotes Committee has the full power and authority to, among other things:

amend the Duke Energy PremierNotes Plan and the Notes offering to the extent described below under “Termination, Suspension or Modification;”

interpret the provisions of the Plan;

adopt rules and regulations in connection with administration of the Plan;

redeem the Notes in whole or in part at any time;

redeem any investments in the Notes of an investor who has abused or misused the investment or redemption provisions applicable to the Notes, whose investments are otherwise inconsistent with the objectives of the Duke Energy PremierNotes Plan or who is not eligible to invest in the Notes, in each case as determined by the Duke Energy PremierNotes Committee in its sole judgment and discretion; and

TABLE OF CONTENTS
 

make certain determinations in accordance with the Duke Energy PremierNotes Plan, including setting the rates of interest to be paid on the Notes.
The Duke Energy PremierNotes Committee (or, the “Committee”) shall consist of at least three persons designated from time to time by Duke Energy. The Committee is currently comprised of the Chief Financial Officer, the Treasurer, an Assistant Treasurer and other members of the Finance and Legal groups of Duke Energy. Our Chief Financial Officer or Treasurer may from time to time remove or appoint other officers or employees of Duke Energy to serve on the Committee and may designate an alternate for each member, who shall have full power to act in the absence or inability to act of such member. As provided in the Duke Energy PremierNotes Plan, the Committee has delegated its authority to determine the interest rate on the Notes to the Treasurer of Duke Energy. The address of each member of the Duke Energy PremierNotes Committee is 525 South Tryon Street, Charlotte, North Carolina 28202. The members of the Duke Energy PremierNotes Committee receive no additional compensation for their Committee services.
The members of the Committee may from time to time have potential conflicts of interest from the point of view of investors in the Notes. All members of the Committee to date have been, and are expected in the future to be, employees of Duke Energy or one of its subsidiaries. All of the money you invest will be invested in the Notes, which are securities of Duke Energy. The members of the Committee have a duty to act in Duke Energy’s best interest, and consequently may make decisions that investors in the Notes do not believe to be in their best interest. In addition, employees of Duke Energy and its subsidiaries, including members of the Committee, may from time to time invest in or redeem the Notes.
Under the Plan, no member of the Committee or a director, officer or employee of Duke Energy or any of its subsidiaries will be liable for any action or failure to act under or in connection with the Plan, except for his or her own bad faith. Duke Energy will indemnify and hold any such person harmless from all loss or expense that may be imposed upon or reasonably incurred by him or her in connection with or resulting from any claim, or proceeding, except a judgment in favor of Duke Energy based upon a finding of his or her bad faith.

tax reporting and filing with the proper authorities.
We pay the agent bank an administrative fee for these services.
DESCRIPTION OF THE NOTES
The Notes are governed by an indenture, dated as of April 4, 2011, between us and The Bank of New York Mellon Trust Company, N.A., which acts as trustee. The trustee has two main roles. First, the trustee can enforce your rights against us if we default. There are some limitations on the extent to which the trustee acts on your behalf, described below under “Events of Default and Notices.” Second, the trustee may perform certain administrative duties for us.
The indenture and its associated documents contain the full legal text of the matters described in this section. The indenture is an exhibit to our registration statement of which this prospectus is a part. See “Where You Can Find More Information” for information on how to obtain a copy of the indenture.
This section summarizes the material terms of the Notes. Because this section is a summary, it does not describe every aspect of the Notes and is subject to and qualified in its entirety by reference to all provisions of the indenture, including definitions of certain terms used in the indenture. We describe the meaning for only the more important of those terms. Whenever we refer to defined terms of the indenture in this prospectus, such defined terms are incorporated by reference here.
General
The Notes will be issuable in any amount and will mature upon your demand. The Notes will be identical except for their issue date and principal amount. We may reject any offer to purchase Notes in whole or in part. All investments in the Notes are investments in our unsecured debt obligations and are not obligations of or guaranteed by our subsidiaries, the agent bank, the trustee or any other company. Duke Energy does not maintain reserves for its obligations under the Notes and the Notes are not subject to any sinking fund. The Notes are redeemable at your option in the manner described in this prospectus.
Following an initial investment, investors may make additional investments and redemptions from time to time as described in this prospectus. As a result, the outstanding principal amount of the Notes will increase and decrease from time to time. For purposes of determining the aggregate amount of registered but unissued notes under the registration statement relating to the Notes, each investment is an issuance of Notes, reducing the capacity of registered but unissued Notes by a corresponding amount. The daily amount and rate of redemptions are affected by many factors, including but not limited to the rates we offer on the Notes from time to time, the wide variety of alternative investment options in the market that are available to our investors and seasonal increases in redemptions and investments.
Although investors could seek to redeem a large dollar amount of Notes over a short period of time, we believe that we have sufficient capital resources available to timely fund redemptions of the Notes. Liquidity management is both a daily and long-term component of our treasury management strategy. In the event that we require funds beyond our ability to generate them internally, additional sources of funds are

available to us. For more information, see the discussion of our capital resources and liquidity in our Form 10-K and 10-Q reports filed with the SEC that are incorporated by reference into this prospectus.
The Notes will rank equally in priority with all of Duke Energy’s existing and future unsecured and unsubordinated indebtedness and will rank senior in right of payment to all of Duke Energy’s existing and future subordinated debt. At June 30, 2025, Duke Energy had approximately $28.6 billion of outstanding indebtedness, consisting of approximately $26.6 billion of unsecured and unsubordinated indebtedness and $2.0 billion of unsecured junior subordinated indebtedness. Duke Energy is a holding company, and we operate our businesses through our subsidiaries. The Notes are structurally subordinated to the indebtedness and other liabilities of our subsidiaries. This means that in liquidation the assets of our subsidiaries would be applied first to the repayment of indebtedness and other liabilities of our subsidiaries before they would be available to pay the indebtedness and liabilities of Duke Energy, including the Notes. At June 30, 2025, Duke Energy’s subsidiaries had approximately $57.8 billion of indebtedness, payment upon approximately $650 million of which was guaranteed by Duke Energy. The indenture does not limit our ability to incur additional debt, including debt incurred by our subsidiaries. The indenture also does not restrict us from acquiring or combining with entities that have outstanding indebtedness, which entities may become subsidiaries of Duke Energy.
The indenture does not limit the principal amount of the Notes or any of our other debt that may be issued.
The Notes will be issued in uncertificated form and you will not receive any certificate or other instrument evidencing our indebtedness. All funds you invest in the Notes, together with interest accrued thereon, and redemptions, if any, will be recorded on a register maintained by the agent bank.
The indenture provides that we, the trustee and the investors waive, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to the indenture or the Notes.
Minimum Investment
Because of the relatively high cost of maintaining small investments, we reserve the right to redeem your investment if the investment balance is less than the minimum required investment balance of $1,000 for three consecutive months. If you are an employee or retiree, the minimum required initial investment is only $100 each month until the minimum required investment balance of $1,000 is attained. Thereafter, the $1,000 minimum investment balance must be maintained. If the minimum investment balance is not attained or maintained, we may redeem the principal amount of your Notes, together with accrued and unpaid interest, and mail the proceeds to your registered address. You will be notified if your Notes will be redeemed and you will be permitted 30 days within which to make additional investments to increase your investment balance to the applicable minimum required investment before your investment is redeemed. The minimum required investment balance is subject to change at the discretion of the Duke Energy PremierNotes Committee without prior notice to investors.
Maximum Outstanding Investment
Duke Energy may institute a total maximum outstanding investment for any one investor. As of the date of this prospectus, the Duke Energy PremierNotes Committee has established a total maximum
 
28

TABLE OF CONTENTS
 
outstanding investment for any one investor of $10,000,000. If the amount of your outstanding investment exceeds the maximum for three consecutive months, we may notify you in writing that we intend to redeem the amount of your investment in excess of $10,000,000. You will then have 30 days to redeem the excess portion of your investment. If you do not do so within a 30-day period, we may redeem the amount we have specified and mail a check for the proceeds to the registered holder of the Notes, less any tax withholding, if applicable, and any other fees discussed in this prospectus. Interest on the redeemed amount shall cease to accrue on and after the effective date of the redemption. The total maximum outstanding investment in the Notes for any one investor is subject to change at the discretion of the Duke Energy PremierNotes Committee without prior notice to investors.
We May Redeem the Notes at Our Option
We may also elect to redeem the entire amount of, or any portion of, the outstanding Notes. Any such partial redemption of outstanding Notes will be effected by lot or pro rata or by any other method that is deemed fair and appropriate by the agent bank. We generally will give you 30-days’ prior written notice if the Notes are to be redeemed in whole or in part. As discussed above, we may also redeem your Notes if your investment balance is below the minimum amount or exceeds the maximum amount as determined by the Duke Energy PremierNotes Committee.
In addition, as provided in the Duke Energy PremierNotes Plan, we may also redeem, at any time at our option, the Notes of any investor who is not or is no longer eligible to invest in the Notes, who has abused or misused the investment or redemption provisions applicable to the Notes or whose investments are otherwise inconsistent with the objectives of the Duke Energy PremierNotes Plan, in each case as we determine in our sole judgment and discretion. In the event that we determine to redeem a particular investor’s Notes for any of these reasons, we will notify the investor of our intention to redeem in full the Notes on the third business day following the date of our notice.
In each of the redemption transactions initiated by us, as described above, a redemption check will be sent to the investor in an amount equal to the principal amount of the redeemed Notes, including accrued and unpaid interest and less any applicable fees. Interest on the redeemed amount shall cease to accrue on and after the effective date of redemption.
The Trustee
The indenture contains certain limitations on the right of the trustee, as a creditor of ours, to obtain payment of claims in certain cases, or to realize on certain property received in respect of any such claim as security or otherwise. In addition, the trustee may be deemed to have a conflicting interest and may be required to resign as trustee if at the time of a default under the indenture it is a creditor of ours.
The Bank of New York Mellon Trust Company, N.A. is the trustee under the indenture. Duke Energy and certain of its affiliates maintain deposit accounts and banking relationships with The Bank of New York Mellon Trust Company, N.A. or its affiliates. The Bank of New York Mellon Trust Company, N.A. or its affiliates also serve as trustee or agent under other indentures and agreements pursuant to which securities of Duke Energy and of certain of its affiliates are outstanding.

TABLE OF CONTENTS
 
Events of Default and Notices
The following events are defined in the indenture as “events of default” with respect to the Notes:

failure to pay any or all the principal of or interest on any Note when due, provided that the failure to pay shall not be deemed to be an event of default under various circumstances, such as when the person demanding payment is not legally entitled to it or upon the occurrence of certain administrative errors; and

failure to perform any of our covenants in the indenture, which continues for 60 days after we are given written notice by either the trustee or at least a majority of the holders in principal amount of the Notes outstanding and affected thereby.
If an event of default with respect to the outstanding Notes occurs and is continuing, either the trustee or the holders of at least a majority in principal amount of the outstanding Notes may declare the principal amount of all Notes to be due and payable immediately; provided, however, that under certain circumstances the holders of a majority in aggregate principal amount of outstanding Notes may rescind and annul such declaration and its consequences.
The indenture provides that the trustee, within 90 days after the occurrence of a default with respect to the Notes, shall give to the holders of the Notes notice of all uncured defaults known to it (the term “default” means the events specified above without grace periods), provided that, except in the case of default in the payment of principal of or interest, if any, on any Notes, the trustee shall be protected in withholding the notice if it in good faith determines that the withholding of the notice is in the interest of the holders of Notes.
We will be required to furnish annually to the trustee a statement by certain of our officers to the effect that to their knowledge we are not in default in the fulfillment of any of our obligations under the indenture or, if there has been a default in the fulfillment of any of our obligations, specifying each such default.
The holders of a majority in principal amount of the outstanding Notes will have the right, subject to certain limitations, to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred on the trustee with respect to the Notes, and to waive certain defaults.
The indenture provides that in case an event of default occurs and is continuing, the trustee shall exercise such of its rights and powers under the indenture, and use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs. Subject to such provisions, the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request or direction of any of the holders of Notes unless they shall have offered to the trustee reasonable security or indemnity against the costs, expenses and liabilities which the trustee might incur in complying with the request or direction.
Modification of the Indenture
We and the trustee may modify or amend the indenture, with the consent of the holders of not less than a majority in aggregate principal amount of the outstanding Notes issued under the indenture, provided that no such modification or amendment may, without the consent of each holder of the Notes that are affected:
 
30

TABLE OF CONTENTS
 

change the character of the Notes from being payable on demand or reduce the principal amount of any Note;

impair the right to institute a suit for the enforcement of any payment on or with respect to any Note;

reduce the above-stated percentage of holders of Notes necessary to modify or amend the indenture; or

modify the foregoing requirements or reduce the percentage of outstanding Notes necessary to waive compliance with certain provisions of the indenture or for waiver of certain defaults.
We may also amend the indenture, without the consent of any holders of the Notes, to add covenants or restrictions for your benefit or to make other changes that do not adversely affect the rights of any holder in any material respect.
TERMINATION, SUSPENSION OR MODIFICATION
We expect that you will be able to invest in the Notes for the foreseeable future, but we reserve the right at any time to terminate, to suspend or from time to time to modify the Plan and the Notes offering in part, in its entirety or in respect of investors located in one or more states or other jurisdictions or to suspend new investments in the Notes. We reserve the right to modify, suspend or terminate any of the investment options and redemption options described under “Duke Energy PremierNotes—How to Make an Investment,” “—Primary Investment Options,” “—Other Investment Options” and “—How to Redeem.” No termination, modification or suspension shall affect your rights unless the proposed action shall have been communicated to you in sufficient time prior to its effective date to allow you to redeem Notes together with accrued and unpaid interest in accordance with the terms in effect prior to the effective date of such termination, modification or suspension. No such termination or modification of the Plan or suspension or any provision in the Plan may diminish the principal of any Note or unpaid interest on any Note. Any modification that affects the rights or duties of the trustee may be made only with the consent of the trustee.
The indenture shall cease to be of further effect, and the trustee, on our demand and at our cost and expense, shall execute proper instruments acknowledging satisfaction of and discharging the indenture if at any time we shall have terminated the Plan pursuant to its provisions, all of the Notes shall have become due and payable, we shall have deposited or caused to be deposited with the trustee as trust funds the entire amount sufficient to pay all the outstanding Notes, including principal and interest due or to become due to such date of maturity or, if we shall have given notice for the full redemption of all outstanding Notes, the date of redemption, and we shall have paid or caused to be paid all other sums payable by us under the indenture.
RIGHTS MAY NOT BE ASSIGNED, TRANSFERRED OR PLEDGED
Except for redemptions, and except for the right to debit amounts credited in error to investment balances, there is no provision in the Plan, in the indenture or in our arrangements with the agent bank under which any person has or may create any lien on amounts credited to your investment balance in the Notes. You may not assign, transfer or pledge rights under the Notes, except upon redemption.

PLAN OF DISTRIBUTION
We have engaged Georgeson Securities Corporation (“GSC”) to assist us with the offering of the Notes as an accommodating broker in states where applicable securities laws require such offerings to be made by a registered broker-dealer. GSC is a registered broker-dealer in all fifty U.S. states. GSC is not underwriting the Notes, has no obligation to purchase any Notes and is not obligated to find or qualify purchasers of the Notes. GSC has not prepared a report or opinion constituting recommendations or advice to us in connection with the Notes. In addition, GSC does not make any recommendations as to whether any investor should purchase the Notes. No commissions will be paid to GSC. We will pay GSC an annual administrative fee of $25,000 for its services with respect to the Notes. In certain jurisdictions, we are offering the Notes on a continuing basis directly on our behalf. We may also from time to time designate other agents through whom Notes may be offered. We reserve the right to withdraw, cancel or modify the offer to purchase Notes at any time. We have the sole right to accept offers to purchase Notes and may reject any proposed purchase of Notes in whole or in part.

Delaware law permits a corporation to adopt a provision in its certificate of incorporation eliminating or limiting the personal liability of a director, but not an officer in his or her capacity as such, to the corporation or its shareholders for monetary damages for breach of fiduciary duty as a director, except that such provision shall not eliminate or limit the liability of a director for (i) any breach of the director’s duty of loyalty to the corporation or its shareholders, (ii) acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) liability under section 174 of the Delaware General Corporation Law (the “DGCL”) for unlawful payment of dividends or stock purchases or redemptions, or (iv) any transaction from which the director derived an improper personal benefit. Our certificate of incorporation provides that no director of ours shall be personally liable to us or our shareholders for monetary damages for breach of fiduciary duty as a director, except to the extent such an exemption from liability or limitation thereof is not permitted under applicable law.
Under Delaware law, a corporation may indemnify any person made a party or threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, other than action by or in the right of the corporation, because he or she is or was an officer, director, employee or agent of the corporation or was serving at the request of the corporation as an officer, director, employee or agent of another corporation or entity against expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred in connection with such action, suit or proceeding: (1) if he or she acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation; or (2) in the case of a criminal proceeding, he or she had no reasonable cause to believe that his or her conduct was unlawful. A corporation may indemnify any person made a party or threatened to be made a party to any threatened, pending or completed action or suit brought by or in the right of the corporation because he or she was an officer, director, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or other entity, against expenses actually and reasonably incurred in connection with such action or suit if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation, provided that such indemnification will be denied if the person is found liable to the corporation unless, in such a case, the court determines the person is entitled to indemnification for such expenses in any event. A corporation must indemnify a present or former director or officer who successfully defends himself or herself in a proceeding to which he or she was a party because he or she was a director or officer of the corporation against expenses actually and reasonably incurred by him or her. Expenses incurred by an officer or director, or any employees or agents as deemed appropriate by the board of directors, in defending civil or criminal proceedings may be paid by the corporation in advance of the final disposition of such proceedings upon receipt of an undertaking by or on behalf of such director or officer to repay such amount if it shall ultimately be determined that he or she is not entitled to be indemnified by the corporation. The Delaware law regarding indemnification and

expense advancement is not exclusive of any other rights which may be granted by our certificate of incorporation or bylaws, a vote of shareholders or disinterested directors, agreement or otherwise.
Under the DGCL, termination of any proceeding by conviction or upon a plea of nolo contendere or its equivalent shall not, of itself, create a presumption that such person is prohibited from being indemnified.
Our bylaws provide that we shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of us), by reason of the fact that such person is or was a director or officer of us, or is or was a director or officer serving at our request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to our best interests, and, with respect to any criminal action or proceeding, had no reasonable cause to believe such person’s conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which such person reasonably believed to be in or not opposed to our best interests, and, with respect to any criminal action or proceeding, had reasonable cause to believe that such person’s conduct was unlawful.
Our bylaws further provide that we shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of us to procure a judgment in its favor by reason of the fact that such person is or was a director or officer of us, or is or was a director or officer of us serving at our request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection with the defense or settlement of such action or suit if such person acted in good faith, and in a manner such person reasonably believed to be in or not opposed to our best interests except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to us unless and only to the extent that the Court of Chancery of the State of Delaware or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.
However, our bylaws provide that we will only provide indemnification pursuant to the bylaws (unless ordered by a court) if such indemnification is authorized in the specific case upon a determination that indemnification of the present or former director or officer is proper in the circumstances because such person has met the applicable standard of conduct set forth in the bylaws. Such determination shall be made, with respect to a person who is a director or officer at the time of such determination, (i) by a majority vote of the directors who are not parties to such action, suit or proceeding, even though less than a quorum, or (ii) by a committee of directors who are not parties to such action, suit or proceeding designated by a majority vote of directors who are not parties to such an action, suit or proceeding, even though less than a quorum, or (iii) if there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion, or (iv) by the shareholders. Such determination shall be made, with respect to former directors and officers, by any person or persons having the authority to act on the matter on our behalf. To the extent, however, that a present or former director or officer of ours has been successful on the merits or otherwise in defense of any action, suit or proceeding, or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection therewith, without the necessity of authorization in the specific case.
Our bylaws further provide that except for proceedings to enforce rights to indemnification, we shall not be obligated to indemnify any director or officer (or his or her heirs, executors or personal or legal representatives) or advance expenses in connection with a proceeding (or part thereof) initiated by such person unless such proceeding (or part thereof) was authorized or consented to by the board of directors.
The indemnification and advancement of expenses provided by, or granted pursuant to, our bylaws are not deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses

may be entitled under the certificate of incorporation, bylaws, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in such person’s official capacity and as to action in another capacity while holding such office. It is our policy that indemnification shall generally be made to the fullest extent permitted by law. Our bylaws do not preclude indemnifying persons in addition to those specified in the bylaws but whom we have the power or obligation to indemnify under the provisions of the DGCL, or otherwise.
We may also purchase and maintain insurance on behalf of any person who is or was a director or officer, or is or was a director or officer serving at our request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person’s status as such, whether or not we would have the power or the obligation to indemnify such person against such liability under the provisions of the bylaws.
The Duke Energy PremierNotes Plan provides for the indemnification of officers and directors of Duke Energy under certain circumstances.
Item 16.   Exhibits.
The exhibits to this registration statement are listed in the exhibit index, which appears elsewhere herein and is incorporated by reference.
Item 17.   Undertakings.
(a)   The undersigned registrant hereby undertakes:
(1)   To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:
(i)   To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933, as amended;
(ii)   To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;
(iii)   To include any material information with respect to the plan of distribution not previously disclosed in the registration statement, or any material change to such information in the registration statement;
provided, however, that paragraphs (i), (ii) and (iii) do not apply if the registration statement is on Form S-3 or Form F-3 and the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Securities and Exchange Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.
(2)   That, for the purpose of determining any liability under the Securities Act of 1933, as amended, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(3)   To remove from registration by means of a post-effective amendment any of the securities being registered that remain unsold at the termination of the offering.

(4)   That, for the purpose of determining liability under the Securities Act of 1933, as amended, to any purchaser:
(i)   Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and
(ii)   Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933, as amended, shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.
(5)   That, for the purpose of determining liability of the registrant under the Securities Act of 1933, as amended, to any purchaser in the initial distribution of the securities the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:
(i)   Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;
(ii)   Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;
(iii)   The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and
(iv)   Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.
(b)   The undersigned registrant hereby further undertakes that, for purposes of determining any liability under the Securities Act of 1933, as amended, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(c)   Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended, may be permitted to directors, officers and controlling persons of the registrant pursuant to the provisions described under Item 15 in the registration statement above, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted

against the registrant by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
