We are offering $500,000,000 principal amount of our Floating Rate Notes due 2020, which we refer to in this prospectus supplement as our “notes.” The notes will bear interest at a rate equal to three-month LIBOR plus 0.50% per annum and will mature on October 9, 2020.

We will pay interest on the notes quarterly on January 9, April 9, July 9 and October 9 of each year, commencing on January 9, 2018.

We do not have the right to redeem the notes prior to maturity. If a change of control triggering event occurs, we will be required to offer to purchase the notes at a purchase price equal to 101% of their principal amount, plus accrued and unpaid interest, if any, to, but excluding, the date of purchase. See “Description of the Notes—Change of Control Offer.”

The notes will be our senior unsecured obligations and will rank equally with all our other senior unsecured debt from time to time outstanding, but will be effectively junior to our secured indebtedness and will not be the obligation of any of our subsidiaries.

The notes are a new issue of securities with no established trading market. We do not intend to apply for listing of the notes on any securities exchange or any automated quotation system.

Investing in the notes involves risks that are described or referred to in the “Risk Factors” section beginning on page S-6 of this prospectus supplement.

The indenture governing the notes will contain certain restrictions, including a limitation that restricts our ability and the ability of certain of our subsidiaries to create or incur secured debt. Certain sale and leaseback transactions will be similarly limited. See “Description of the Notes—Certain Covenants.”

Ranking

The notes will be our senior unsecured obligations, will rank equally with all our other senior unsecured debt, including all of our other unsubordinated notes, from time to time outstanding, and will be structurally subordinated to the secured and unsecured debt of Conagra Brands’ subsidiaries. The notes will be exclusively our obligation, and not the obligation of any of our subsidiaries. Our rights and the rights of any holder of notes (or other of our creditors) to participate in the assets of any subsidiary upon that subsidiary’s liquidation or recapitalization will be subject to the prior claims of the subsidiary’s creditors, except to the extent that we may be a creditor with recognized claims against the subsidiary.

Risk factors

See “Risk Factors” and other information in this prospectus supplement and the accompanying prospectus for a discussion of factors that should be carefully considered before investing in the notes.

Conflict of interest

One or more of the underwriters may have a “conflict of interest” under FINRA Rule 5121(f)(5)(C)(ii). See “Underwriting (Conflict of Interest).”

An investment in the notes involves risk. Prior to making a decision about investing in the notes, and in consultation with your own financial and legal advisors, you should carefully consider the following risk factors regarding the notes and this offering, as well as the risk factors incorporated by reference in this prospectus supplement from our Annual Report on Form 10-K for the year ended May 28, 2017 and our Quarterly Report on Form 10-Q for the quarterly period ended August 27, 2017 under the heading “Risk Factors,” and other filings we may make from time to time with the SEC. You should also refer to the other information included or incorporated by reference in this prospectus supplement and the accompanying prospectus, including our financial statements and the related notes. Additional risks and uncertainties that are not yet identified may also materially harm our business, operating results and financial condition and could result in a complete loss of your investment.

Our existing and future debt may limit cash flow available to invest in the ongoing needs of our business and could prevent us from fulfilling our obligations under our outstanding debt securities, as well as the notes.

As of August 27, 2017, we had total long-term debt, including current installments, of approximately $2,965.7 million outstanding. We have the ability under our existing revolving credit facility to incur substantial additional debt. Our level of debt could have important consequences. For example, it could:

Additionally, any failure to meet required payments on our debt, or failure to comply with any covenants in the instruments governing our debt, could result in an event of default under the terms of those instruments and a downgrade to our credit ratings. A downgrade in our credit ratings would increase our borrowing costs and could affect our ability to issue commercial paper. In the event of a default, the holders of our debt could elect to declare all the amounts outstanding under such instruments to be due and payable. Any default under the agreements governing our debt and the remedies sought by the holders of such debt could render us unable to pay principal and interest on our debt.

The notes are subject to prior claims of any secured creditors and the creditors of our subsidiaries and if a default occurs we may not have sufficient funds to fulfill our obligations under the notes.

The notes are unsecured general obligations of Conagra Brands, Inc., ranking equally with other senior unsecured debt of Conagra Brands, Inc. but effectively junior to any senior secured debt of Conagra Brands, Inc. and the debt and other liabilities of our subsidiaries. The indenture governing the notes will permit us and our subsidiaries to incur secured debt under specified circumstances. If we incur any secured debt, our assets and the assets of our subsidiaries will be subject to prior claims by our secured creditors. In the event of our bankruptcy, liquidation, reorganization or other winding up, assets that secure debt will be available to pay obligations on the notes only after all debt secured by those assets has been repaid in full. Holders of the notes will participate in our remaining assets ratably with all of our unsecured and unsubordinated creditors, including our trade creditors.

If Conagra Brands, Inc. incurs any additional obligations that rank equally with the notes, including trade payables, the holders of those obligations will be entitled to share ratably with the holders of the notes in

any proceeds distributed upon the insolvency, liquidation, reorganization, dissolution or other winding up of Conagra Brands, Inc. This may have the effect of reducing the amount of proceeds paid to you. If there are not sufficient assets remaining to pay all these creditors, all or a portion of the notes then outstanding would remain unpaid.

The indenture will not limit the amount of debt we may incur or restrict our ability to engage in other transactions that may adversely affect holders of our notes.

The indenture under which the notes will be issued will not limit the amount of debt that we may incur. The indenture will not contain any financial covenants or other provisions that would afford the holders of the notes any substantial protection in the event we participate in a highly leveraged transaction. In addition, the indenture will not limit our ability to pay dividends, make distributions or repurchase shares of our common stock. Any such transaction could adversely affect you.

We depend on cash flow of our subsidiaries to make payments on our securities.

Conagra Brands, Inc. is in part a holding company. Our subsidiaries conduct a significant percentage of our consolidated operations and own a significant percentage of our consolidated assets. Consequently, our cash flow and our ability to meet debt service obligations of Conagra Brands, Inc. depends in large part upon the cash flow of our subsidiaries and the payment of funds by the subsidiaries to us in the form of loans, dividends or otherwise. Our subsidiaries are not obligated to make funds available to us for payment of the notes or otherwise. In addition, their ability to make any payments will depend on their earnings, the terms of their debt, business and tax considerations and legal restrictions. The notes will effectively rank junior to all liabilities of our subsidiaries. In the event of a bankruptcy, liquidation or dissolution of a subsidiary and following payment of its liabilities, the subsidiary may not have sufficient assets remaining to make payments to us as a shareholder or otherwise.

The notes are a new issue of securities with no established trading market. We do not intend to apply for listing of the notes on any securities exchange or to have the notes quoted on any automated quotation system. Accordingly, there can be no assurance that a trading market for the notes will ever develop or will be maintained. If a trading market does not develop or is not maintained, you may find it difficult or impossible to resell the notes. Further, there can be no assurance as to the liquidity of any market that may develop for the notes, your ability to sell the notes or the price at which you will be able to sell the notes. Future trading prices of the notes will depend on many factors, including prevailing interest rates, our financial condition and results of operations, the then-current ratings assigned to the notes and the markets for similar securities. Any trading market that develops would be affected by many factors independent of and in addition to the foregoing, including:

The underwriters have advised us that they currently intend to make a market in the notes, but they are not obligated to do so and may cease market-making at any time without notice.

We expect that the notes will be rated by one or more nationally recognized statistical rating organizations. A rating is not a recommendation to purchase, hold or sell debt securities, since a rating does not predict the market price of a particular security or its suitability for a particular investor. Any rating organization

that rates the notes may lower our rating or decide not to rate the notes in its sole discretion. The ratings of the notes will be based primarily on the rating organization’s assessment of the likelihood of timely payment of interest when due and the payment of principal on the maturity date. Any downgrade or withdrawal of a rating by a rating agency that rates the notes could have an adverse effect on the trading prices or liquidity of the notes.

Holders of notes may not be able to determine when a change of control giving rise to their right to have the notes repurchased by us has occurred following a sale of “substantially all” of our assets.

A “Change of Control” may require us to make an offer to repurchase all outstanding notes (see “Description of the Notes—Change of Control Offer”). The definition of change of control includes a phrase relating to the sale of “all or substantially all” of our assets. There is no precise established definition of the phrase “substantially all” under applicable law. Accordingly, the ability of a holder of notes to require us to repurchase its notes as a result of a sale of less than all of our assets to another individual, group or entity may be uncertain.

We may not be able to repurchase all of the notes upon a change of control triggering event, which would result in a default under the notes.

We will be required to offer to repurchase the notes upon the occurrence of a “Change of Control Triggering Event” as provided by the terms of the notes. However, we may not have sufficient funds to repurchase the notes in cash at such time. In addition, our ability to repurchase the notes for cash may be limited by law or the terms of other agreements relating to our debt outstanding at the time. The failure to make such repurchase would result in a default under the notes.

We may, without the consent of the holders of the notes, create and issue additional notes ranking equally with the notes and otherwise similar in all respects (except for the issue date, public offering price and, in some cases, the initial interest payment date) so that any outstanding notes and the additional notes form a single series under the indenture.

The amount of interest payable on the notes is set only once per period based on the three-month LIBOR on the interest determination date, which rate may fluctuate substantially.

In the past, the level of the three-month LIBOR has experienced significant fluctuations. You should note that historical levels, fluctuations and trends of the three-month LIBOR are not necessarily indicative of future levels. Any historical upward or downward trend in the three-month LIBOR is not an indication that the three-month LIBOR is more or less likely to increase or decrease at any time during a floating rate interest period, and you should not take the historical levels of the three-month LIBOR as an indication of its future performance. You should further note that although the actual three-month LIBOR on an interest payment date or at other times during an interest period may be higher than the three-month LIBOR on the applicable interest determination date, you will not benefit from the three-month LIBOR at any time other than on the interest determination date for such interest period. As a result, changes in the three-month LIBOR may not result in a comparable change in the market value of the notes. Increases in the three-month LIBOR rate as of any interest determination date will require us to make higher interest payments on the notes.

Uncertainty relating to the LIBOR calculation process and potential phasing out of LIBOR after 2021 may adversely affect the value of the notes.

Regulators and law enforcement agencies in the United Kingdom and elsewhere are conducting civil and criminal investigations into whether the banks that contribute to the British Bankers’ Association, or BBA, in connection with the calculation of daily LIBOR may have been under-reporting or otherwise manipulating or attempting to manipulate LIBOR. A number of BBA member banks have entered into settlements with their regulators and law enforcement agencies with respect to this alleged manipulation of LIBOR.

Actions by the BBA, regulators or law enforcement agencies may result in changes to the manner in which LIBOR is determined or the establishment of alternative reference rates. For example, on July 27, 2017, the U.K. Financial Conduct Authority announced that it intends to stop persuading or compelling banks to submit LIBOR rates after 2021. Furthermore, in the United States, efforts to identify a set of alternative U.S. dollar reference interest rates include proposals by the Alternative Reference Rates Committee of the Federal Reserve Board and the Federal Reserve Bank of New York. At this time, it is not possible to predict the effect of any such changes, any establishment of alternative reference rates or any other reforms to LIBOR that may be enacted in the United Kingdom or elsewhere. Uncertainty as to the nature of such potential changes, alternative reference rates or other reforms may adversely affect the trading market for LIBOR-based securities, including the notes. To the extent the three-month LIBOR is discontinued or is no longer quoted, the applicable base rate used to calculate interest on the notes will be determined using the alternative methods described in “Description of the Notes.”

We expect to receive net proceeds, after deducting underwriting discounts and estimated offering expenses payable by us, of approximately $497.0 million from this offering. We intend to use the net proceeds from this offering for general corporate purposes, including the repayment of outstanding commercial paper at maturity and the repurchase of our common stock. As of October 6, 2017, we had $187.2 million of borrowings outstanding under our commercial paper program with an average weighted interest rate of 1.39% and an average weighted maturity of six days.

One or more of the underwriters participating in this offering or its affiliates are dealers under our commercial paper program and, accordingly, such underwriters or affiliates will receive proceeds from this offering through the repayment of our commercial paper. See “Underwriting (Conflict of Interest).”

The following table sets forth our consolidated cash and cash equivalents and capitalization as of August 27, 2017. You should read this table in conjunction with our unaudited consolidated financial statements, the related notes and other financial information contained in our Quarterly Report on Form 10-Q for the quarterly period ended August 27, 2017, which is incorporated by reference into this prospectus supplement and the accompanying prospectus.

At August 27, 2017, we had a $1.25 billion (which, subject to certain conditions, may be increased to a maximum amount of $1.75 billion) multi-year revolving credit facility with a syndicate of financial institutions that matures in February 2022. The revolving credit facility has historically been used principally as a back-up facility for our commercial paper program. As of August 27, 2017, there were no outstanding borrowings under the revolving credit facility. As of October 6, 2017, we had $187.2 million of borrowings outstanding under our commercial paper program with an average weighted interest rate of 1.39% and an average weighted maturity of six days.

Loans (other than “bid loans”) under the revolving credit facility bear interest, at our election, either at (a) LIBOR plus a percentage spread (ranging from 0.91% to 1.50%) based on our unsecured senior long-term debt ratings or (b) the alternate base rate, described in the credit agreement as the greatest of (i) Bank of America N.A.’s prime rate, (ii) the federal funds rate plus 0.50% and (iii) one-month LIBOR plus 1.00%, plus a percentage spread (ranging from 0.0% to 0.50%) based on our unsecured senior long-term debt ratings. Additionally, we have the right to request of the lenders (although the lenders have no obligation to provide) “bid loans” with a lower, fixed interest rate.

Borrowings under the revolving credit facility generally may be prepaid without penalty.

The revolving credit facility contains affirmative and negative covenants customary for such financings, including, but not limited to, covenants limiting our ability to:

The revolving credit facility contains financial covenants requiring a maximum leverage ratio and a minimum interest coverage ratio. As of August 27, 2017, we were in compliance with the credit agreement’s financial covenants.

The revolving credit facility contains events of default customary for such financings, including, but not limited to:

As of August 27, 2017, we had an aggregate principal amount of $2,950.2 million of long-term debt outstanding. The specific amounts, maturity and interest rates of such long-term debt is set forth in the following table.

Our existing senior notes were all issued under the indenture, dated as of October 8, 1990, which we refer to as the existing senior indenture, between us and The Bank of New York Mellon (as successor to JPMorgan Chase Bank, N.A. and The Chase Manhattan Bank (National Association)), as trustee. The senior notes are the direct, unsecured obligations of Conagra Brands, Inc. and are not guaranteed by any of our subsidiaries. The existing senior indenture does not directly limit the amount of other debt that may be incurred by Conagra Brands, Inc. or our subsidiaries. Subject to several enumerated exceptions, the existing senior indenture prohibits us and certain of our subsidiaries from securing any debt or other obligation with any principal property or shares of capital stock of certain of our subsidiaries without providing that our senior notes under the existing senior indenture shall be secured equally and ratably with the secured debt or other obligation for so long as the secured debt or other obligation remains secured, except to the extent the amount of the secured debt or other obligation, along with the value of permitted sale and lease-back transactions, does not exceed 10% of our consolidated net tangible assets, as defined in the existing senior indenture. The existing senior indenture restricts our ability to enter into sale and lease-back transactions as well as to consolidate, merge or sell all or substantially all of our assets. These existing senior notes have substantially the same covenants, change of control provisions and events of default as provided with respect to the notes, as described below in “Description of the Notes.”

Our 6.7% senior notes due 2027 are redeemable at the option of the note holders at 100% of the principal amount of the notes together with interest payable to the date of repayment.

Our 9.75% subordinated notes due 2021 were issued under an indenture, dated as of February 7, 1991 (as supplemented by a supplemental indenture dated February 18, 1991), which we refer to as the existing subordinated indenture, between us and U.S. Bank National Association (as successor to First Trust National Association), as trustee. These subordinated notes are the direct, unsecured obligations of Conagra Brands, Inc., are not guaranteed by any of our subsidiaries and are subordinate and junior in right of payment, to the extent and manner set forth in the existing subordinated indenture, to all of our senior debt. The existing subordinated indenture does not directly limit the amount of other debt that may be incurred by us or our subsidiaries. The existing subordinated indenture restricts our ability to enter into sale and lease-back transactions as well as to consolidate, merge or sell all or substantially all of our assets.

You can find the definitions of certain terms used in this description under the subheading “Certain Covenants—Certain Definitions Relating to Certain Covenants.”

The notes will be issued under an indenture to be entered into between us and Wells Fargo Bank, National Association, as trustee, which we refer to as the Trustee, as supplemented by the first supplemental indenture (the indenture as so supplemented, the “indenture”), between us and the Trustee. The terms of the notes include those stated in the indenture and the notes, as well as those made part of the indenture by reference to the Trust Indenture Act of 1939, as amended. The notes will constitute senior debt securities to be issued under the indenture.

This description of the notes supplements and, to the extent inconsistent therewith, replaces the section entitled “Description of Debt Securities” included in the accompanying prospectus. Because this section is a summary, it does not describe every aspect of the indenture or the notes. This summary is subject to and qualified in its entirety by reference to all of the provisions of the indenture, including definitions of certain terms used in the indenture, and the notes. You should read the indenture and the notes because they contain additional information and they, and not this description, define your rights as a holder of the notes. A copy of the indenture will be filed with the SEC. Additionally, copies of the forms of indenture and notes are available without charge upon request to us at the address provided under “Information We Incorporate By Reference.” For purposes of this section, references to “Conagra Brands,” “we,” “us” or “our” include only Conagra Brands, Inc. and not any of its subsidiaries.

We will initially issue $500.0 million aggregate principal amount of the notes in this offering. We may, without the consent of the holders of the notes, create and issue additional senior debt securities ranking equally with the notes and otherwise similar in all respects (except for the issue date, public offering price and, in some cases, the initial interest payment date) so that any outstanding notes and the additional senior debt securities form a single series under the indenture.

The notes will mature on October 9, 2020. The notes will accrue interest at a variable rate reset each interest period as described below. Interest on the notes will be payable quarterly on January 9, April 9, July 9 and October 9, commencing on January 9, 2018, to the persons in whose names such notes are registered at the close of business on each December 25, March 25, June 24 and September 24 preceding the applicable interest payment date, whether or not a business day.

The interest rate for the notes for a particular interest period will be a per annum rate equal to the three-month LIBOR as determined on the applicable interest determination date by the calculation agent appointed by us, which initially will be the Trustee, plus 0.50%.

The interest rate on the notes will be reset on the first day of each interest period other than the initial interest period, each such date an “interest reset date.” An interest period is the period commencing on an interest payment date (or, in the case of the initial interest period, commencing on the date that the notes are issued) and ending on the day immediately preceding the next interest payment date or the maturity date, as the case may be. The initial interest period is October 12, 2017 through, but excluding, January 9, 2018. The interest determination date for an interest period will be the second London Banking Day preceding the first day of such interest period. The initial interest determination date for the initial interest period will be October 10, 2017.

The amount of interest payable on the notes will be computed on the basis of the actual number of days in each quarterly interest period and a 360-day year. In the event that any day (other than the maturity date) on which interest is payable on the notes is not a business day, then payment of the interest payable on such date

will be made on the next succeeding day which is a business day and interest will accrue to but excluding the date interest is paid; provided, that if such next succeeding business day does not occur in the calendar month of the relevant interest payment date, payment will be made on the business day immediately preceding the interest payment date.

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

(1) With respect to any interest determination date, LIBOR will be the rate for deposits in United States dollars having a maturity of three months commencing on the first day of the applicable interest period that appears on Reuters Screen LIBOR01 Page, or, if on such interest determination date, the three-month LIBOR does not appear or is not available on Reuters Screen LIBOR01 Page, such other service as may be nominated by the ICE Benchmark Administration Limited for the purpose of displaying London interbank offered rates for U.S. dollar deposits of major banks, as of 11:00 a.m., London time, on that interest determination date. If no rate appears, then LIBOR, in respect of that interest determination date, will be determined in accordance with the provisions described in (2) below.

(2) With respect to an interest determination date on which no rate appears on either of the pages specified in (1) above, we will request the principal London offices of each of four major reference banks in the London interbank market, as selected by us, to provide the calculation agent with its offered quotation for deposits in United States dollars for the period of three months, commencing on the first day of the applicable interest period, to prime banks in the London interbank market at approximately 11:00 a.m., London time, on that interest determination date and in a principal amount that is representative for a single transaction in United States dollars in that market at that time. If at least two quotations are provided, then LIBOR on that interest determination date will be the arithmetic mean of those quotations. If fewer than two quotations are provided, then LIBOR on the interest determination date will be the arithmetic mean of the rates quoted at approximately 11:00 a.m., in The City of New York, on the interest determination date by three major banks in The City of New York selected by us for loans in United States dollars to leading European banks, having a three-month maturity and in a principal amount that is representative for a single transaction in United States dollars in that market at that time; provided, however, that if the banks selected by us are not providing quotations in the manner described by this sentence, LIBOR will be the same as the rate determined for the immediately preceding interest reset date or if there is no immediately preceding interest reset date, LIBOR will be the same as the rate determined for the initial interest period.

“London Banking Day” means any day in which dealings in United States dollars are transacted or, with respect to any future date, are expected to be transacted in the London inter-bank market.

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

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

The interest rate on the notes will in no event be higher than the maximum rate permitted by New York law as the same may be modified by United States laws of general application.

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

When we use the term “business day,” we mean any day except a Saturday, a Sunday or a legal holiday in The City of New York on which banking institutions are authorized or required by law or regulation to close.

Each holder that is a transferor of a note shall provide or cause to be provided to the Trustee all information reasonably requested by the Trustee and reasonably available to such holder as necessary to allow the Trustee to comply with any cost basis reporting obligations under Internal Revenue Code Section 6045. The Trustee may rely on information provided to it by or on behalf of such holder and shall have no responsibility to verify or ensure the accuracy of such information.

Our subsidiaries are distinct legal entities having no obligation to pay any amounts pursuant to, or to make funds available for, the notes.

As of August 27, 2017, we had outstanding $2,769.8 million of senior unsecured debt, not including commercial paper, and $195.9 million of subordinated unsecured debt.

No mandatory redemption obligation will be applicable to the notes. The notes will not be subject to, nor have the benefit of, a sinking fund.

If a Change of Control Triggering Event occurs, each holder of notes will have the right to require us to purchase all or any part (equal to $2,000 and any integral multiples of $1,000 in excess thereof) of such holder’s notes pursuant to the offer described below, which we refer to as a “Change of Control Offer,” at a purchase price equal to 101% of the aggregate principal amount of the notes repurchased, plus accrued and unpaid interest, if any, to, but excluding, the date of repurchase, subject to the rights of holders of notes on the relevant record date to receive interest due on the relevant interest payment date.

We will be required to deliver a notice to each holder of the notes, with a copy to the Trustee, within 30 days following the date upon which any Change of Control Triggering Event occurred, or at our option, prior

to any Change of Control but after the public announcement of the pending Change of Control. The notice will govern the terms of the Change of Control Offer and will describe, among other things, the transaction that constitutes or may constitute the Change of Control Triggering Event and the purchase date. The purchase date will be at least 30 days but no more than 60 days from the date such notice is delivered, other than as may be required by law, which we refer to as a “Change of Control Payment Date.” If the notice is delivered prior to the date of consummation of the Change of Control, the notice will state that the Change of Control Offer is conditioned on the Change of Control being consummated on or prior to the Change of Control Payment Date.

We will not be required to make a Change of Control Offer upon the occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for such an offer made by us and the third party purchases all notes properly tendered and not validly withdrawn under its offer.

We will comply with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws and regulations thereunder, to the extent those laws and regulations are applicable, in connection with the repurchase of the notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the notes, we will comply with those securities laws and regulations and will not be deemed to have breached our obligations under the Change of Control Offer provisions of the notes by virtue of any such conflict.

The definition of Change of Control includes a phrase relating to the direct or indirect sale, lease, transfer, conveyance or other disposition of “all or substantially all” of our properties or assets and those of our subsidiaries taken as a whole. Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise established definition of the phrase under applicable law. Accordingly, the ability of a holder of notes to require us to repurchase the notes as a result of a sale, lease, transfer, conveyance or other disposition of less than all of our assets and the assets of our subsidiaries, taken as a whole to another person or group may be uncertain.

“Capital Stock” means the capital stock of every class whether now or hereafter authorized, regardless of whether such capital stock shall be limited to a fixed sum or percentage with respect to the rights of the holders thereof to participate in dividends and in the distribution of assets upon the voluntary or involuntary liquidation, dissolution or winding up of such corporation.

Notwithstanding the foregoing, a transaction will not be considered to be a Change of Control if (a) we become a direct or indirect wholly-owned subsidiary of a holding company and (b)(x) immediately following that transaction, the direct or indirect holders of the Voting Stock of the holding company are substantially the same as the holders of our Voting Stock immediately prior to that transaction or (y) immediately following that transaction, no person is the beneficial owner, directly or indirectly, of more than fifty percent (50%) of the Voting Stock of such holding company.

“Change of Control Triggering Event” means the occurrence of both a Change of Control and a Rating Event. Notwithstanding the foregoing, no Change of Control Triggering Event will be deemed to have occurred in connection with any particular Change of Control unless and until such Change of Control has actually been consummated.

“Continuing Directors” means, as of any date of determination, any member of our Board of Directors who:

“Investment Grade” means a rating of Baa3 or better by Moody’s (or its equivalent under any successor rating categories of Moody’s), a rating of BBB- or better by S&P (or its equivalent under any successor rating categories of S&P) and a rating of BBB- or better by Fitch (or its equivalent under any successor rating categories of Fitch).

“Moody’s” means Moody’s Investors Service, Inc., a subsidiary of Moody’s Corporation, and its successors.

“Rating Event” means (i) the rating of the notes is lowered by two of the three Rating Agencies on any day during the period, which we refer to as the “Trigger Period,” commencing on the earlier of (a) the occurrence

of a Change of Control and (b) the first public notice of our intention to effect a Change of Control, and ending 60 days following consummation of such Change of Control (which period shall be extended so long as the rating of the notes is under publicly announced consideration for possible downgrade by any two of the three Rating Agencies), and (ii) the notes are rated below Investment Grade by each of the Rating Agencies on any day during the Trigger Period; provided that a Rating Event will not be deemed to have occurred in respect of a particular Change of Control (and thus will not be deemed a Rating Event for purposes of the definition of Change of Control Triggering Event) if each Rating Agency making the reduction in rating does not publicly announce or confirm or inform us that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the Change of Control (whether or not the applicable Change of Control has occurred at the time of the Rating Event).

“S&P” means S&P Global Ratings, a division of S&P Global Inc., and its successors.

“Voting Stock” means, with respect to any specified person as of any date, the Capital Stock of such person that is at the time entitled to vote generally in the election of the Board of Directors of such person.

The Depository Trust Company, New York, New York, which we refer to as the Depository or DTC, will be the depositary with respect to the notes. The notes will be issued as global securities registered in the name of Cede & Co., the Depository’s partnership nominee, and deposited with the Depository. See “—Book-Entry; Delivery and Form” for further information.

All payments of principal and interest on the notes will be made by Conagra Brands in immediately available funds. The notes will trade in DTC’s Same-Day Funds Settlement System until maturity, and secondary market trading activity in the notes will therefore be required by DTC to settle in immediately available funds.

For important additional information applicable to the notes, see “Description of Debt Securities” in the accompanying prospectus. That information includes:

We may, directly or indirectly, without the consent of the Trustee or the holders of the notes, merge or consolidate with, or sell, convey, transfer, lease or otherwise dispose of all or substantially all of our properties or assets to, another person, provided that:

Following any such transaction, except in the case of a lease, we will be relieved of all obligations under the indenture and the notes.

We will not, and we will not permit any Consolidated Subsidiary to issue, assume or guarantee any Indebtedness secured by a Lien upon or with respect to any Principal Property or on the capital stock of any Consolidated Subsidiary that owns any Principal Property unless:

Neither we nor any Consolidated Subsidiary may enter into any Sale and Lease-Back Transaction. Such limitation will not apply to any Sale and Lease-Back Transaction if:

We will file with the Trustee, within 15 days after we are required to file the same with the SEC, after giving effect to any grace period provided by Rule 12b-25 under the Exchange Act, copies of the annual reports and of the information, documents and other reports (or copies of such portions of any of the foregoing as the SEC may from time to time by rules and regulations prescribe) that we may be required to file with the SEC pursuant to Section 13 or Section 15(d) of the Exchange Act. If we are not required to file information, documents or reports pursuant to either of those sections, then we will file with the Trustee and the SEC, in accordance with rules and regulations prescribed from time to time by the SEC and within 15 days after such information, documents or reports are due with respect to a non-accelerated filer and after giving effect to any grace period provided by Rule 12b-25 under the Exchange Act, such information, documents or reports that may be required pursuant to Section 13 of the Exchange Act in respect of a security listed and registered on a national securities exchange as may be prescribed from time to time in such rules and regulations.

Notwithstanding the foregoing, (a) we will be deemed to have furnished such information, documents or reports referred to above to the Trustee if we have filed such information, documents or reports with the SEC via the EDGAR filing system (or any successor system) or, if at any time we are no longer subject to reporting under Section 13 or 15(d) of the Exchange Act and are not permitted to file such information, documents or reports with the SEC, if we post such information, documents or reports on our publicly available website and (b) if at any time we are no longer subject to the reporting requirements of Section 13 or Section 15(d) of the Exchange Act, we will not be deemed to have failed to comply with any of our obligations under this covenant until 30 days after the date any information, document or report hereunder is required to be filed with the Trustee. The Trustee shall not be obligated to monitor or confirm, on a continuing basis or otherwise, our compliance with the covenants or with respect to any reports or other documents filed with the SEC or EDGAR or any website under the indenture.

“Attributable Debt” means the present value, determined as set forth in the indenture, of the obligation of a lessee for rental payments for the remaining term of any lease.

“Consolidated Net Tangible Assets” means the Net Tangible Assets of us and our Consolidated Subsidiaries consolidated in accordance with generally accepted accounting principles and as provided in the definition of Net Tangible Assets. In determining Consolidated Net Tangible Assets, minority interests in unconsolidated subsidiaries shall be included.

“Consolidated Subsidiary” and “Consolidated Subsidiaries” mean a subsidiary or subsidiaries the accounts of which are consolidated with ours in accordance with generally accepted accounting principles.

“Funded Indebtedness” means all Indebtedness of a corporation which would, in accordance with generally accepted accounting principles, be classified as funded debt. Funded Indebtedness will also, in any event, include all Indebtedness, whether secured or unsecured, of a corporation which has a final maturity, or a maturity renewable or extendable at the option of the corporation, more than one year after the date as of which Funded Indebtedness is to be determined.

“Indebtedness” means any and all of the obligations of a corporation for money borrowed which in accordance with generally accepted accounting principles would be reflected on the balance sheet of the corporation as a liability as of the date of which Indebtedness is to be determined.

“Lien” means any mortgage, pledge, security interest or other lien or encumbrance.

“Net Tangible Assets” means the total amount of assets of a corporation, both real and personal, less the sum of:

The definition of Net Tangible Assets excludes licenses, patents, patent applications, copyrights, trademarks, trade names, goodwill, experimental or organizational expense and other like intangibles, treasury stock and unamortized discount and expense.

“Principal Property” means, as of any date, any building, structure or other facility together with the underlying land and its fixtures, used primarily for manufacturing, processing or production, in each case located in the United States, and owned or leased or to be owned or leased by us or any Consolidated Subsidiary, and in each case the net book value of which as of such date exceeds 2% of Consolidated Net Tangible Assets as shown on the audited consolidated balance sheet contained in the latest annual report to our stockholders, other than any such land, building, structure or other facility or portion thereof which, in the opinion of our Board of Directors, is not of material importance to the business conducted by us and our Consolidated Subsidiaries, considered as one enterprise.

“Sale and Lease-Back Transactions” means any arrangement with any person providing for the leasing by us or a Consolidated Subsidiary of any Principal Property that we or such Consolidated Subsidiary has sold or transferred or is about to sell or transfer to such person. However, the definition does not include temporary leases for a term of not more than three years or transactions between us and a Consolidated Subsidiary.

This description of “Events of Default” replaces and supersedes the section entitled “Events of Default” included in the accompanying prospectus. An “Event of Default” is defined under the indenture with respect to the notes as being:

If an Event of Default (other than an Event of Default due to certain events of bankruptcy, insolvency and reorganization involving us) occurs and is continuing, then either the Trustee or the holders of at least 25% in aggregate principal amount of the notes may declare the principal amount of all notes and interest accrued thereon to be due and payable immediately.

If an Event of Default due to certain events of bankruptcy, insolvency and reorganization involving us occurs and is continuing, then the principal amount of all notes and interest accrued thereon will automatically become immediately due and payable without any declaration or other act on the part of the Trustee or any holder.

Under certain circumstances, the holders of a majority in principal amount of the notes may, by written notice to us and the Trustee, rescind a declaration that the principal amount of and accrued interest on the notes are due and payable immediately if such rescission would not conflict with any judgment or decree already rendered and if all existing Events of Default with respect to the notes (except nonpayment of principal or interest that has become due solely because of the acceleration) have been cured or waived.

The holders of a majority in aggregate principal amount of the outstanding notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on the Trustee, provided that such direction may not be in conflict with any rule of law or the indenture. Before proceeding to exercise any right or power under the indenture at the direction of such holders, the Trustee is entitled to receive from such holders security or indemnity satisfactory to it against any loss, liability or expense which might be incurred by acting in compliance with any such direction.

We furnish to the Trustee annually a statement from one of our officers to the effect that, to the best of their knowledge, we are not in default of the performance of the terms of the indenture or, if they have knowledge that we are in default, specifying the default.

The indenture provides that no holder of notes may institute any action against us under the indenture, except actions for payment of overdue principal or interest, unless all of the following occurs:

The indenture requires the Trustee to give all of the holders of outstanding notes notice of any default by us with respect to the notes, as provided in the Trust Indenture Act of 1939, as amended, unless the default has been cured or waived. Except in the case of a default in the payment of principal of, and any premium or interest on, any outstanding notes, the Trustee is entitled to withhold such notice in the event that a committee of certain officers of the Trustee in good faith determines that withholding such notice is in the interest of the holders of the outstanding notes.

The provisions described in “Description of Debt Securities—Defeasance of Debt Securities and Certain Covenants in Certain Circumstances” in the accompanying prospectus will be applicable to the notes, including the covenants described under “—Change of Control Offer,” “—Certain Covenants—Limitation on Liens,” “—Certain Covenants—Limitation on Sale and Lease-Back Transactions” and “—Certain Covenants—SEC Reports.”

The notes and the indenture will be governed by and construed in accordance with the laws of the State of New York.

Wells Fargo Bank, National Association is the Trustee under the indenture. From time to time, we and our subsidiaries maintain ordinary banking relationships with the Trustee, and Wells Fargo Securities, LLC, an affiliate of the Trustee, is one of the underwriters.

The Trustee assumes no responsibility for the accuracy or completeness of the information concerning us or our affiliates or any other party contained in this prospectus supplement and the accompanying prospectus or for any failure by us or any other party to disclose events that may have occurred and may affect the significance or accuracy of such information. Neither the Trustee nor any paying agent shall be responsible for monitoring our rating status, making any request upon any Rating Agency, or determining whether any Rating Event with respect to the notes has occurred.

Except as set forth below, the notes will be issued in registered global form in minimum denominations of $2,000 and multiples of $1,000 in excess of that amount.

The notes will initially be represented by one or more fully registered global notes, which we refer to collectively as the global notes. Each such global note will be deposited upon issuance with the Trustee as custodian for DTC, and registered in the name of DTC or its nominee, in each case for credit to an account of a direct or indirect participant in DTC as described below. Transfers of beneficial interests in the global notes will be subject to the applicable rules and procedures of DTC and its direct or indirect participants (including, if applicable, those of Euroclear and Clearstream), which may change from time to time.

The following are summaries of certain rules and operating procedures of DTC that affect the payment of principal and interest and the transfers of interests in the global notes. The notes will be issued only in the form of definitive global securities that will be deposited with, or on behalf of, DTC and registered in the name of Cede & Co., as nominee of DTC. Unless and until they are exchanged in whole or in part for notes in definitive form under the limited circumstances described below, a global note may not be transferred except as a whole (1) by DTC to a nominee, (2) by a nominee of DTC to DTC or another nominee of DTC or (3) by DTC or any such nominee to a successor of DTC or a nominee of such successor. Accountholders in the Euroclear or Clearstream Banking clearance systems may hold beneficial interests in the notes through the accounts that each of these systems maintain as participants in DTC.

Ownership of beneficial interests in the global notes will be limited to persons that have accounts with DTC for such global notes, who we refer to as participants, or persons that may hold interests through participants. Upon the issuance of the global notes, DTC will credit, on its book-entry registration and transfer system, the participants’ accounts with the respective principal amounts of the notes represented by such global note beneficially owned by such participants. Ownership of beneficial interests in the global notes will be shown on, and the transfer of such ownership interests will be effected only through, records maintained by DTC (with respect to interests of participants). 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 participant through which the beneficial owner entered into the transaction. Transfers of ownership interests in the global notes are to be accomplished by entries made on the books of participants acting on behalf of beneficial owners. Beneficial owners will not receive certificates representing their ownership interest in the global notes, except in the event that use of the book-entry system for the global notes is discontinued. The laws of some states may require that certain purchasers of securities take physical delivery of such securities in definitive form. Such laws may limit or impair the ability to own, transfer or pledge beneficial interests in the global notes.

So long as DTC or its nominee is the registered owner of the global notes, DTC or its nominee, as the case may be, will be considered the sole owner or holder of the notes represented by such global notes for all purposes under the indenture. Except as set forth below, owners of beneficial interests in the global notes will not be entitled to have notes represented by such global notes registered in their names, will not receive or be entitled to receive physical delivery of such notes in certificated form and will not be considered the registered owners or holders thereof under the indenture. Accordingly, each person owning a beneficial interest in the global notes must rely on the procedures of DTC and, if such person is not a participant, on the procedures of the participant through which such person owns its interest, to exercise any rights of a holder under the indenture. We understand that under existing industry practices, if we request any action of holders or if an owner of a beneficial interest in any of the global notes desires to give or take any action that a holder is entitled to give or take under the indenture, DTC would authorize the participants holding the relevant beneficial interests to give or take such action, and such participants would authorize beneficial owners owning through such participants to give or to take such action or would otherwise act upon the instructions of beneficial owners holding through them.

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. Beneficial owners may wish to take certain steps to augment the transmission to them of notices of significant events with respect to the global notes, such as redemptions, tenders, defaults, and proposed amendments to the note documents. Beneficial owners may ascertain that the nominee holding the global notes for their benefit has agreed to obtain and transmit notices to beneficial owners or beneficial owners may provide their names and addresses to the registrar and request that copies of notices be provided directly to them.

Principal and interest payments on interests represented by the global notes will be made to DTC or its nominee, as the case may be, as the registered owner of such global notes. None of Conagra Brands, the Trustee or any other agent of Conagra Brands or agent of the Trustee will have any responsibility or liability for any facet of the records relating to or payments made on account of beneficial ownership of interests. We expect that DTC, upon receipt of any payment of principal or interest in respect of the global notes, will immediately credit participants’ accounts with payments in amounts proportionate to their respective beneficial interests in such global notes as shown on the records of DTC. We also expect that payments by participants to owners of beneficial interests in the global notes held through such participants will be governed by standing customer instructions and customary practice, as is now the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of such participants.

If DTC is at any time unwilling or unable to continue as depository for the global notes, and we fail to appoint a successor depository registered as a clearing agency under the Exchange Act within 90 days, we will

issue notes in definitive form in exchange for the global notes. Any notes issued in definitive form in exchange for such global notes will be registered in such name or names, and will be issued in denominations of $2,000 and integral multiples of $1,000 as DTC shall instruct the Trustee. It is expected that such instructions will be based upon directions received by DTC from participants with respect to ownership of beneficial interests in the global notes. In connection with any proposed transfer of definitive notes in exchange for global notes, we or DTC shall be required to provide or cause to be provided to the Trustee all information reasonably requested by the Trustee and reasonably available to us or DTC, as applicable, as necessary to allow the Trustee to comply with any cost basis reporting obligations under Internal Revenue Code Section 6045. The Trustee may rely on information provided to it by or on behalf of us or DTC, as applicable, and shall have no responsibility to verify or ensure the accuracy of such information.

DTC has advised that it is a limited purpose trust company organized under the Banking Law of the State of New York, 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 was created to hold the securities of its participants and to facilitate the clearance and settlement of transactions among its participants in such securities through electronic book-entry changes in accounts of the participants, thereby eliminating the need for physical movement of securities certificates. DTC’s participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations, some of which (and/or their representatives) directly or indirectly own DTC. Access to the DTC book-entry system is also available to others, such as banks, brokers and dealers and trust companies that clear through or maintain a custodial relationship with a participant, either directly or indirectly.

The following is a summary of certain U.S. federal income tax considerations with respect to the acquisition, ownership and disposition of the notes, but it does not purport to be a complete analysis of all the potential tax considerations relating to the acquisition, ownership and disposition of the notes. This summary is based upon the provisions of the Internal Revenue Code of 1986, as amended (the “Code”), applicable U.S. Treasury Regulations promulgated thereunder, administrative rulings and judicial decisions, all as of the date of this prospectus supplement. These authorities may be changed or subject to differing interpretations, possibly with retroactive effect. We have not obtained, nor do we intend to obtain, a ruling from the Internal Revenue Service (the “IRS”) with respect to the statements made in this summary and there can be no assurance that the IRS will agree with such statements or that a court would not sustain a challenge by the IRS in the event of litigation.

This summary is limited to beneficial owners of the notes (“Holders”) that purchase the notes upon their initial issuance at their “initial offering price” (i.e., the first price at which a substantial amount of the notes is sold for cash to investors (excluding sales to bond houses, brokers or similar persons or organizations acting in the capacity as underwriters, placement agents or wholesalers)) and that will hold the notes as “capital assets” within the meaning of Section 1221 of the Code (generally, property held for investment). This summary does not address the tax considerations arising under the laws of any foreign, state, local or other jurisdiction. In addition, this summary does not address any U.S. federal tax considerations other than U.S. federal income tax considerations that may be relevant to Holders’ particular circumstances, or to certain categories of Holders that may be subject to special rules, such as:

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds notes, the U.S. federal income tax treatment of a partner in such partnership generally will depend upon the status of the partner and the activities of the partnership. If you are a partnership or a partner in a partnership that will hold notes, you are urged to consult your own tax advisor regarding the tax consequences to you of acquiring, holding and disposing of the notes.

This summary of certain U.S. federal income tax considerations is for general information only and is not tax advice. You are urged to consult your tax advisor with respect to the application of U.S. federal income tax laws to your particular situation as well as any tax considerations arising under other U.S. federal tax laws (such as the estate or gift tax laws) or under the laws of any state, local, foreign or other taxing jurisdiction or under any applicable tax treaty.

In certain circumstances (see “Description of the Notes—Change of Control Offer”), we may become obligated to make payments on the notes in excess of stated interest and principal. The obligation to make these payments may implicate Treasury Regulations relating to “contingent payment debt instruments” which, if applicable, could cause the timing, amount and character of a Holder’s income, gain or loss with respect to the notes to be different from the consequences discussed below. For purposes of determining whether a debt instrument is a contingent payment debt instrument, contingencies that are remote or incidental (determined as of the date the notes are issued) are ignored. We believe the possibility of paying additional amounts on the notes to be remote and/or incidental in the aggregate, and therefore do not intend to treat the notes as contingent payment debt instruments. Our treatment will be binding on all Holders of the notes, except a Holder that discloses its differing treatment in a statement attached to its timely filed U.S. federal income tax return for the taxable year during which the note was acquired. Our treatment is not binding on the IRS, which may take a contrary position. You are urged to consult your own tax advisors regarding the potential application to the notes of the rules regarding contingent payment debt instruments and the consequences thereof. The remainder of this discussion assumes the notes will not be treated as contingent payment debt instruments.

The following discussion is a summary of the general U.S. federal income tax consequences that will apply to you if you are a “U.S. Holder.” For purposes of this discussion, a U.S. Holder is a beneficial owner of a note that is, for U.S. federal income tax purposes:

It is anticipated, and this discussion assumes, that the notes will be issued at par or at a discount that is no more than “de minimis” original issue discount for U.S. federal income tax purposes. Stated interest on the notes will generally be taxable to you as ordinary income at the time it is paid or accrued in accordance with your method of accounting for U.S. federal income tax purposes.

Upon the sale, exchange, redemption, retirement or other taxable disposition of a note, you will recognize taxable gain or loss equal to the difference between the amount realized on such disposition (except to the extent any amount realized is attributable to accrued but unpaid interest, which, if not previously included in income, will be treated as interest as described above) and your adjusted tax basis in the note. Your adjusted tax basis in a note generally will be your cost for the note. Gain or loss recognized on the disposition of a note generally will be capital gain or loss, and will be long-term capital gain or loss if, at the time of such disposition, your holding period for the note is more than 12 months. Long-term capital gains of non-corporate taxpayers are generally eligible for preferential rates of taxation. The deductibility of capital losses is subject to certain limitations.

An additional 3.8% Medicare tax is imposed on the “net investment income” of certain U.S. citizens and resident aliens, and on the undistributed “net investment income” of certain estates and trusts. Among other items, “net investment income” generally includes gross income from interest, and certain net gain from the sale, redemption, exchange, retirement or other taxable disposition of property, such as the notes, less certain deductions. You are urged to consult your own tax advisor with respect to the Medicare tax and its applicability in your particular circumstances to income and gains in respect of an investment in the notes.

In general, information reporting requirements will apply to payments of interest and the proceeds of certain sales and other taxable dispositions (including retirements or redemptions) of notes unless you are an exempt recipient. Backup withholding (at a rate of 28%) will apply to such payments if you fail to provide your taxpayer identification number (“TIN”), provide an incorrect TIN, have been notified by the IRS that payments to you are subject to backup withholding, or fail to certify, under penalties of perjury, that you have provided your correct TIN and are not subject to backup withholding (generally on a properly completed and executed IRS Form W-9). Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will generally be allowed as a credit against your U.S. federal income tax liability and may entitled you to a refund, provided that you furnish the required information to the IRS on a timely basis.

The following is a summary of the general U.S. federal income tax consequences that will apply to you if you are a “Non-U.S. Holder” of the notes. You are a “Non-U.S. Holder” if you are a beneficial owner of a note that is an individual, corporation, estate or trust and that is not a U.S. Holder.

Subject to the discussion of backup withholding and FATCA withholding below, payments of interest on the notes to you generally will be exempt from U.S. federal income tax and withholding tax under the “portfolio interest” exemption if you properly certify as to your foreign status (as described below) and:

If you cannot satisfy the requirements described above for the portfolio interest exemption, payments of interest made to you on the notes will be subject to the 30% U.S. federal withholding tax, unless you provide us either with (1) a properly executed IRS Form W-8BEN or IRS Form W-8BEN-E, as applicable (or appropriate substitute or successor form), establishing an exemption from (or a reduction of) withholding under the benefit of an applicable income tax treaty or (2) a properly executed IRS Form W-8ECI (or appropriate substitute or successor form) certifying that interest paid on the note is not subject to withholding tax because the interest is effectively connected with your conduct of a trade or business in the United States (as discussed below under “—Income or gain effectively connected with a United States trade or business”).

Subject to the discussion of backup withholding and FATCA withholding below, you generally will not be subject to U.S. federal income or withholding tax on any gain realized on the sale, exchange, redemption, retirement or other taxable disposition of a note unless:

If you are a Non-U.S. Holder as described in the first bullet point, see “—Income or gain effectively connected with a United States trade or business” below. If you are a Non-U.S. Holder as described in the second bullet point, you will generally be subject to U.S. federal income tax at a rate of 30% on the amount by which your capital gains allocable to United States sources, including gain from such disposition, exceed any capital losses allocable to United States sources, except as otherwise required by an applicable income tax treaty.

To the extent that the amount realized on a sale, redemption, exchange, 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 gain effectively connected with a United States trade or business

If you are engaged in the conduct of a trade or business in the United States and interest on a note or gain recognized from the sale, exchange, redemption, retirement or other taxable disposition of a note is effectively connected with the conduct of that trade or business, you will generally be subject to U.S. federal income tax (but not the 30% U.S. federal withholding tax on interest if certain certification requirements are satisfied) on that interest and on gain on a net income basis in the same manner as if you were a “United States person” (as defined in the Code). You can generally meet these certification requirements by providing a properly executed IRS Form W-8ECI or appropriate substitute form to us, or our paying agent. If you are eligible for the benefits of an income tax treaty between the United States and your country of residence, any effectively connected income or gain generally will be subject to U.S. federal income tax only if it is also attributable to a permanent establishment or fixed base maintained by you in the United States. In addition, if you are a foreign

corporation, you may be subject to an additional branch profits tax equal to 30% (or a lower applicable income tax treaty rate) of your earnings and profits for the taxable year, subject to adjustments, that are effectively connected with your conduct of a trade or business in the United States.

Generally, information returns will be filed with the IRS in connection with payments of interest on the notes and proceeds from the sale or other taxable disposition (including a retirement or redemption) of the notes. Copies of the information returns reporting such payments and any withholding may also be made available to the tax authorities in the country in which you reside under the provisions of an applicable income tax treaty. You may be subject to backup withholding of tax on payments of interest and, depending on the circumstances, the proceeds of a sale or other taxable disposition (including a retirement or redemption) unless you comply with certain certification procedures to establish that you are not a U.S. person. The certification procedures required to claim an exemption from withholding of tax on interest described above generally will satisfy the certification requirements necessary to avoid backup withholding as well. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will generally be allowed as a credit against your U.S. federal income tax liability and may entitle you to a refund, provided that you furnish the required information to the IRS on a timely basis. You are urged to consult your own tax advisor regarding the application of backup withholding rules in your particular situation, the availability of an exemption from backup withholding and the procedure for obtaining such an exemption, if applicable.

Sections 1471 through 1474 of the Code and the Treasury Regulations and administrative guidance issued thereunder (“FATCA”) impose a 30% withholding tax on any U.S.-source interest paid on or after July 1, 2014, on debt obligations such as the notes, issued on or after July 1, 2014, and on the gross proceeds from a disposition of such obligations paid on or after January 1, 2019, in each case, if paid to a “foreign financial institution” or a “non-financial foreign entity” (each as defined in the Code), including when acting as an intermediary, unless: (i) in the case of a foreign financial institution, such institution enters into an agreement with the IRS to withhold on certain payments, and to collect and provide to the IRS information regarding U.S. account holders of such institution (which includes certain equity and debt holders of such institution, as well as certain account holders that are non-U.S. entities with United States owners); (ii) in the case of a non-financial foreign entity, such entity certifies that it does not have any “substantial United States owners” (as defined in the Code) or provides the withholding agent with a certification identifying its direct and indirect substantial United States owners; or (iii) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States with respect to these rules may be subject to different rules. Under certain circumstances, a beneficial owner of notes might be eligible for refunds or credits of such taxes. The rules under FATCA are complex. We will not pay any additional amounts in respect of any amounts withheld, including pursuant to FATCA. You are encouraged to consult with your own tax advisor regarding the implications of FATCA on an investment in the notes.

The discussion of U.S. federal income tax considerations set forth above is included for general information only and is not tax advice. Prospective purchasers of the notes are urged to consult their own tax advisors with respect to the particular tax consequences to them of the purchase, ownership and disposition of notes, including the tax consequences under United States federal, state, local, foreign and other tax laws and the possible effects of changes in applicable tax laws.

The following summary regarding certain aspects of the Employee Retirement Income Security Act of 1974 (“ERISA”) and the Code is based on ERISA and the Code, judicial decisions and United States Department of Labor and IRS regulations and rulings that are in existence on the date of this prospectus supplement. This summary is general in nature and does not address every issue pertaining to ERISA or the Code that may be applicable to us, the notes or a particular investor. Accordingly, each prospective investor should consult with his, her or its own counsel in order to understand the issues relating to ERISA and the Code that affect or may affect the investor with respect to this investment.

ERISA and the Code impose certain requirements on employee benefit plans that are subject to Title I of ERISA and plans subject to Section 4975 of the Code (each such employee benefit plan or plan, a “Plan”), on entities whose underlying assets include plan assets by reason of a Plan’s investment in such entities and on those persons who are “fiduciaries” as defined in Section 3(21) of ERISA and Section 4975 of the Code with respect to Plans. In considering an investment of the assets of a Plan subject to Part 4 of Subtitle B of Title I of ERISA in the notes, a fiduciary must, among other things, discharge its duties solely in the interest of the participants of such Plan and their beneficiaries and for the exclusive purpose of providing benefits to such participants and beneficiaries and defraying reasonable expenses of administering the Plan. A fiduciary must act prudently and must diversify the investments of a Plan subject to Part 4 of Subtitle B of Title I of ERISA so as to minimize the risk of large losses, as well as discharge its duties in accordance with the documents and instruments governing such Plan. In addition, ERISA generally requires fiduciaries to hold all assets of a Plan subject to Part 4 of Subtitle B of Title I of ERISA in trust and to maintain the indicia of ownership of such assets within the jurisdiction of the district courts of the United States. A fiduciary of a Plan subject to Part 4 of Subtitle B of Title I of ERISA should consider whether an investment in the notes satisfies these requirements.

An investor who is considering acquiring the notes with the assets of a Plan must consider whether the acquisition and holding of the notes will constitute or result in a non-exempt prohibited transaction. Section 406(a) of ERISA and Sections 4975(c)(1)(A), (B), (C) and (D) of the Code prohibit certain transactions that involve a Plan and a “party in interest” as defined in Section 3(14) of ERISA or a “disqualified person” as defined in Section 4975(e)(2) of the Code with respect to such Plan. Examples of such prohibited transactions include, but are not limited to, sales or exchanges of property (such as the notes) or extensions of credit between a Plan and a party in interest or disqualified person. Section 406(b) of ERISA and Sections 4975(c)(1)(E) and (F) of the Code generally prohibit a fiduciary with respect to a Plan from dealing with the assets of the Plan for its own benefit (for example when a fiduciary of a Plan uses its position to cause the Plan to make investments in connection with which the fiduciary (or a party related to the fiduciary) receives a fee or other consideration).

ERISA and the Code contain certain exemptions from the prohibited transactions described above, and the Department of Labor has issued several exemptions, although certain exemptions do not provide relief from the prohibitions on self-dealing contained in Section 406(b) of ERISA and Sections 4975(c)(1)(E) and (F) of the Code. Exemptions include Section 408(b)(17) of ERISA and Section 4975(d)(20) of the Code pertaining to certain transactions with non-fiduciary service providers; Department of Labor Prohibited Transaction Class Exemption (“PTCE”) 95-60, applicable to transactions involving insurance company general accounts; PTCE 90-1, regarding investments by insurance company pooled separate accounts; PTCE 91-38, regarding investments by bank collective investment funds; PTCE 84-14, regarding investments effected by a qualified professional asset manager; and PTCE 96-23, regarding investments effected by an in-house asset manager. There can be no assurance that any of these exemptions will be available with respect to the acquisition of the notes. Under Section 4975 of the Code, excise taxes are imposed on disqualified persons who participate in non-exempt prohibited transactions (other than a fiduciary acting only as such) and such transactions may have to be rescinded.

As a general rule, a governmental plan, as defined in Section 3(32) of ERISA (each, a “Governmental Plan”), a church plan, as defined in Section 3(33) of ERISA, that has not made an election under Section 410(d) of the Code (each, a “Church Plan”) and a plan maintained outside the United States primarily for the benefit of

persons substantially all of whom are nonresident aliens (each, a “non-U.S. Plan”) are not subject to Title I of ERISA or Section 4975 of the Code. Accordingly, assets of such plans may be invested without regard to the fiduciary and prohibited transaction considerations described above. Although a Governmental Plan, a Church Plan or a non-U.S. Plan is not subject to Title I of ERISA or Section 4975 of the Code, it may be subject to other United States federal, state or local laws or non-U.S. laws that regulate its investments (a “Similar Law”). A fiduciary of a Government Plan, a Church Plan or a non-U.S. Plan should consider whether investing in the notes satisfies the requirements, if any, under any applicable Similar Law.

The notes may be acquired by a Plan, a Governmental Plan, a Church Plan, a non-U.S. Plan or an entity whose underlying assets include the assets of a Plan, a Governmental Plan, a Church Plan or a non-U.S. Plan, but only if the acquisition will not result in a non-exempt prohibited transaction under ERISA or Section 4975 of the Code or a violation of Similar Law. Therefore, any investor in the notes will be deemed to represent and warrant to us and the trustee that (1)(a) it is not (i) a Plan, (ii) a Governmental Plan, (iii) a Church Plan, (iv) a non-U.S. Plan or (v) an entity whose underlying assets include the assets of a Plan, a Governmental Plan, a Church Plan or a non-U.S. Plan, (b) it is a Plan or an entity whose underlying assets include the assets of a Plan and the acquisition and holding of the notes will not result in a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code, or (c) it is a Governmental Plan, a Church Plan, a non-U.S. Plan or an entity whose underlying assets include the assets of a Governmental Plan, a Church Plan or a non-U.S. Plan that is not subject to (i) ERISA, (ii) Section 4975 of the Code or (iii) any Similar Law that prohibits or imposes excise or penalty taxes on the acquisition or holding of the notes; and (2) it will notify us and the trustee immediately if, at any time, it is no longer able to make the representations contained in clause (1) above. Any purported transfer of the notes to a transferee that does not comply with the foregoing requirements shall be null and void ab initio.

Neither we, nor the Trustee, any underwriter, or any of our respective affiliates, agents or employees (the “Transaction Parties”) will act as a fiduciary to any Plan with respect to the Plan’s decision to invest in the notes, and none of the Transaction Parties is undertaking to provide impartial investment advice or to give advice in a fiduciary capacity in connection with any Plan’s acquisition of the notes. Each fiduciary or other person with investment responsibilities over the assets of a Plan considering an investment in the notes must carefully consider the above factors before making an investment.

In addition, the person making the decision to acquire a note on behalf of a Plan (the “Plan Fiduciary”) from a Transaction Party will be deemed to have represented and warranted that (1) none of the Transaction Parties has provided or will provide advice with respect to the acquisition of a note by the Plan, other than to the Plan Fiduciary which is independent of the Transaction Parties, and the Plan Fiduciary either: (a) is a bank as defined in Section 202 of the Investment Advisers Act of 1940 (the “Advisers Act”), or similar institution that is regulated and supervised and subject to periodic examination by a state or federal agency; (b) is an insurance carrier which is qualified under the laws of more than one state to perform the services of managing, acquiring or disposing of assets of a Plan; (c) is an investment adviser registered under the Advisers Act, or, if not registered as an investment adviser under the Advisers Act by reason of paragraph (1) of Section 203a of the Advisers Act, is registered as an investment adviser under the laws of the state in which it maintains its principal office and place of business; (d) is a broker-dealer registered under the Exchange Act; or (e) has, and at all times during the Plan’s holding of a note will have, total assets of at least U.S. $50,000,000 under its management or control (provided that this clause (e) shall not be satisfied if the Plan Fiduciary is either (i) the owner or a relative of the owner of the individual retirement account that is acquiring the note, or (ii) a participant or beneficiary of the Plan acquiring the note in such capacity); (2) the Plan Fiduciary is capable of evaluating investment risks independently, both in general and with respect to particular transactions and investment strategies, including the acquisition of a note by the Plan; (3) the Plan Fiduciary is a “fiduciary” with respect to the Plan within the meaning of Section 3(21) of ERISA, Section 4975 of the Code, or both, and is responsible for exercising independent judgment in evaluating the Plan’s acquisition of the note; (4) none of the Transaction Parties has exercised any authority to cause the Plan to acquire the note or to negotiate the terms of such acquisition; (5) none of the Transaction Parties receives a fee or other compensation from the Plan or the Plan Fiduciary for the provision of investment advice in connection with the decision to acquire the note; and (6) the Plan Fiduciary

has been informed by the Transaction Parties: (a) (i) that none of the Transaction Parties is undertaking to provide impartial investment advice or to give advice in a fiduciary capacity, and (ii) that no such entity has given investment advice or otherwise made a recommendation, in connection with the Plan’s acquisition of a note (other than advice, if any, given by a Transaction Party to an independent Plan Fiduciary that meets the requirements of clause (1) above); and (b) of the existence and nature of the Transaction Parties’ financial interests in the Plan’s acquisition of a note. The above representations are intended to comply with the DOL’s Reg. Sections 29 C.F.R. 2510.3-21(a) and (c)(1) as promulgated on April 8, 2016 (81 Fed. Reg. 20,997). If these regulations are revoked, repealed or no longer effective, these representations shall be deemed to be no longer in effect.

This offer is not a representation by us or the underwriters that an acquisition of the notes meets any or all legal requirements applicable to investments by Plans, Governmental Plans, Church Plans, non-U.S. Plans or entities whose underlying assets include the assets of a Plan, a Governmental Plan, a Church Plan or a non-U.S. Plan or that such an investment is appropriate for any particular Plan, Governmental Plan, Church Plan, non-U.S. Plan or entity whose underlying assets include the assets of a Plan, a Governmental Plan, a Church Plan or a non-U.S. Plan.

Subject to the terms and conditions set forth in the underwriting agreement dated October 10, 2017 among us and the underwriters, each of the underwriters named below, for whom Wells Fargo Securities, LLC and HSBC Securities (USA) Inc. are acting as representatives, has severally agreed to purchase from us the principal amount of notes set forth opposite its name below.

The underwriting agreement provides that the obligations of the several underwriters thereunder are subject to approval of certain legal matters by counsel and to various other conditions. The underwriters are obligated to purchase and accept delivery of all of the notes if they purchase any of the notes.

The underwriters propose to offer the notes directly to the public at the public offering price set forth on the cover page of this prospectus supplement and to certain securities dealers at such prices less a concession not in excess of 0.200% per note. The underwriters may allow, and such dealers may re-allow, concessions not in excess of 0.150% per note on sales to other dealers. After the offering of the notes, the public offering price, concessions and other selling terms may be changed by the underwriters. The notes are offered subject to receipt and acceptance by the underwriters and to certain other conditions, including the right to reject orders in whole or in part.

The following table shows underwriting discounts and commissions that we are to pay to the underwriters in connection with the offering of the notes (expressed as a percentage of the principal amount of the notes and dollars in total):

We estimate that our total expenses for this offering, excluding the underwriting discount, will be approximately $1,300,000.

We have agreed to indemnify the underwriters against certain liabilities under the Securities Act or to contribute to payments that the underwriters may be required to make in respect thereof.

The notes are a new issue of securities with no established trading market. The notes will not be listed on any securities exchange or quoted on any automated dealer quotation system. The underwriters may make a market in the notes after completion of the offering, but will not be obligated to do so and may discontinue any market-making activities at any time without notice. No assurance can be given as to the liquidity of the trading markets for the notes or that active public markets for the notes will develop. If active public trading markets for the notes do not develop, the market prices and liquidity of the notes may be adversely affected.

In connection with the offering of the notes, certain of the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the notes. Specifically, the underwriters may over-allot in connection with the offering, creating a short position. In addition, the underwriters may bid for, and purchase, the notes in the open market to cover short positions or to stabilize the prices of the notes. Any of these activities

may stabilize or maintain the market prices of the notes above independent market levels, but no representation is made hereby of the magnitude of any effect that the transactions described above may have on the market prices of the notes. The underwriters will not be required to engage in these activities, and may engage in these activities and may end any of these activities at any time without notice.

As described under “Use of Proceeds,” the net proceeds of this offering will be used for general corporate purposes, including the repayment of outstanding commercial paper at maturity and the repurchase of our common stock. To the extent that net proceeds from this offering are applied to repay commercial paper held by any of the underwriters or their affiliates, they will receive proceeds of this offering through the repayment of that indebtedness. If 5% or more of the net proceeds of this offering (not including underwriting discounts) is used to repay commercial paper held by at least one of the underwriters or its affiliates, this offering will be conducted in accordance with Rule 5121 of the Financial Industry Regulatory Authority, Inc., or FINRA. In such event, such underwriter or underwriters will not confirm sales of the notes to accounts over which they exercise discretionary authority without the prior written approval of the customer.

The underwriters and their affiliates have provided, are currently providing and in the future may continue to provide investment banking, commercial banking and other financial services, including the provision of credit facilities, to us in the ordinary course of business for which they have received and will receive customary compensation. In addition, certain affiliates of the underwriters are, among other things, lenders under our revolving credit facility. Wells Fargo Bank, National Association, an affiliate of Wells Fargo Securities, LLC, serves as a Documentation Agent and a lender under our revolving credit facility and will serve as Trustee under the indenture and affiliates of HSBC Bank USA, N.A., Barclays Capital Inc., Mizuho Securities USA LLC and MUFG Securities Americas Inc. serve as lenders under our revolving credit facility. In the ordinary course of business, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of Conagra Brands or its affiliates. If any of the underwriters 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 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 Conagra Brands securities, including potentially the notes offered hereby. Any such credit default swaps or short positions could adversely affect 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.

In relation to each Relevant Member State, each underwriter has represented and agreed that with effect from and including the date on which the Prospectus Directive is implemented in that Relevant Member State, it has not made and will not make an offer of notes which are the subject of the offering contemplated by this prospectus supplement and the accompanying prospectus to the public in that Relevant Member State other than:

(a) to any legal entity that is a qualified investor (as defined in the Prospectus Directive);

(b) to fewer than 150 natural or legal persons (other than qualified investors as defined in the Prospectus Directive), as permitted under the Prospectus Directive, subject to obtaining the prior consent of the relevant underwriter or underwriters nominated by Conagra Brands, Inc. for any such offer; or

Guided by an entrepreneurial spirit, the Company combines a rich heritage of making great food with a sharpened focus on innovation. The Company’s portfolio is evolving to satisfy people’s changing food preferences. Its iconic brands such as Marie Callender’s^®, Reddi-wip^®, Hunt’s^®, Healthy Choice^®, Slim Jim^®, Orville Redenbacher’s^®, as well as emerging brands, including Alexia^®, Blake’s^®, and Frontera^®, offer choices for every occasion.

Our Grocery & Snacks reporting segment principally includes branded, shelf stable food products sold in various retail channels in the United States.

Our Refrigerated & Frozen reporting segment principally includes branded, temperature controlled food products sold in various retail channels in the United States.

Our International reporting segment principally includes branded food products, in various temperature states, sold in various retail and foodservice channels outside of the United States.

Our Commercial reporting segment included commercially branded and private label food and ingredients, which were sold primarily to commercial, restaurant, foodservice, food manufacturing, and industrial customers. The segment’s primary food items included a variety of vegetable, spice, and frozen bakery goods, which were sold under brands such as Spicetec Flavors & Seasonings^®. In the first quarter of fiscal 2017, we sold our Spicetec and JM Swank businesses. These businesses comprise the entire Commercial segment following the presentation of Lamb Weston as discontinued operations.

We were initially incorporated as a Nebraska corporation in 1919 and were reincorporated as a Delaware corporation in December of 1975. Our principal executive offices are located at 222 Merchandise Mart Plaza, Suite 1300, Chicago, Illinois 60654, and our main telephone number is (312) 549-5000. Our website is www.conagrabrands.com. The information contained on or accessible through our website is not part of this prospectus, other than the documents that we file with the SEC that are incorporated by reference in this prospectus. For additional information concerning Conagra Brands, please see our most recent Annual Report on Form 10-K and our other filings with the SEC, which are incorporated by reference into this document. See “Where You Can Find More Information.”

Investing in our securities involves risk. Prior to making a decision about investing in our securities, you should carefully consider the specific factors discussed under the heading “Risk Factors” in our most recent Annual Report on Form 10-K filed with the SEC, in each case as these risk factors are amended or supplemented by subsequent Quarterly Reports on Form 10-Q, which have been or will be incorporated by reference into this document. The risks and uncertainties we have described are not the only ones we face. Additional risks and uncertainties that are not yet identified may also materially harm our business, operating results and financial condition and could result in a complete loss of your investment.

Unless we otherwise state in the applicable prospectus supplement, we intend to use the net proceeds we receive from the sale of the securities offered by this prospectus and the accompanying prospectus supplement(s) for our operations and for general corporate purposes, including working capital, acquisitions, retirement of debt and other business opportunities.

The following table sets forth our ratio of earnings to fixed charges for the periods presented.

For purposes of calculating the ratio of earnings to fixed charges, earnings are equal to the amount resulting from (1) adding (a) income from continuing operations before income taxes and equity method investment earnings, (b) fixed charges and (c) distributed income of equity method investees and (2) subtracting capitalized interest. Fixed charges are equal to the sum of (1) interest expense, (2) capitalized interest and (3) an estimate of the interest within rental expense.

Because we have no preferred stock issued (and have not had any issued during the fiscal years or periods shown above), a ratio of earnings to combined fixed charges and preferred dividends is not presented.

Our authorized capital stock consists of 1,200,000,000 shares of common stock, par value $5.00 per share; 150,000 shares of Class B preferred stock, $50.00 par value; 250,000 shares of Class C preferred stock, $100.00 par value; 1,100,000 shares of Class D preferred stock, without par value; and 16,550,000 shares of Class E preferred stock, without par value.

The board of directors may declare and pay dividends on our common stock out of funds legally available for that purpose, subject to the rights of holders of preferred stock.

We may issue preferred stock in series with rights and preferences as authorized by our board of directors. We will distribute a prospectus supplement with regard to each series of preferred stock offered under this prospectus. Each prospectus supplement will describe, as to the preferred stock to which it relates:

Our common stock is listed on the New York Stock Exchange under the symbol “CAG”. The holders of our common stock are entitled to one vote for each share. Upon liquidation, the holders of our common stock are entitled to share ratably in assets available for distribution to stockholders after satisfaction of any liquidation preferences of any outstanding preferred stock. The issuance of any shares of any series of preferred stock in future financings, acquisitions or otherwise may result in dilution of voting power and relative equity interest of the holders of shares of our common stock and will subject our common stock to the prior dividend and liquidation rights of the outstanding shares of the series of preferred stock.

The shares of our common stock offered under this prospectus will be fully paid and non-assessable. Our common stock has no conversion rights nor are there any redemption or sinking fund provisions with respect to the common stock. Holders of our common stock have no pre-emptive right to subscribe for or purchase any additional stock or securities of Conagra Brands.

Provisions of Our Amended and Restated Certificate of Incorporation and Delaware Law That May Have an Anti-Takeover Effect

Article XII of our amended and restated certificate of incorporation, which we refer to as our certificate of incorporation, prescribes relevant factors, including social and economic effects on employees, customers, suppliers and other constituents of Conagra Brands, to be considered by the board of directors when reviewing any proposal by another corporation to acquire or combine with Conagra Brands.

Article XIII of our certificate of incorporation requires that any action required or permitted to be taken by Conagra Brands stockholders must be effected at a duly called annual or special meeting of the stockholders and may not be effected by a consent in writing by the stockholders.

Article XIV of our certificate of incorporation provides in general that any direct or indirect purchase by Conagra Brands or any subsidiary of Conagra Brands of any of its voting stock, as defined in Article XIV, or rights to acquire voting stock, known to be beneficially owned by any person or group that holds more than 3% of a class of its voting stock, referred to in this paragraph as an interested stockholder, and that has owned the securities being purchased for less than two years, must be approved by the affirmative vote of at least a majority of the votes entitled to be cast by the holders of the voting stock, excluding voting stock held by an interested stockholder. Article XVIII is intended to prevent “greenmail,” which is a term used to describe the accumulation of a block of a corporation’s stock by a speculator and the subsequent attempt by the speculator to coerce the corporation into repurchasing its shares, typically at a substantial premium over the market price.

We are governed by the provisions of Section 203 of the General Corporation Law of the State of Delaware. In general, Section 203 prohibits a public Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years following the time that the person became an interested stockholder, unless:

A “business combination” includes mergers, asset sales or other transactions resulting in a financial benefit to the stockholder. An “interested stockholder” is a person who, together with affiliates and associates, owns (or within three years did own) 15% or more of the corporation’s voting stock.

The provisions of our certificate of incorporation and Delaware law described in this section may be deemed to have anti-takeover effects. These provisions may discourage or make more difficult an attempt by a stockholder or other entity to acquire control of Conagra Brands. These provisions may also make more difficult an attempt by a stockholder or other entity to remove management.

The following description sets forth certain general terms and provisions of the debt securities that we may issue, which may be issued as convertible or exchangeable debt securities. We will set forth the particular terms of the debt securities we offer in a prospectus supplement and the extent, if any, to which the following general terms and provisions will apply to particular debt securities.

The debt securities will be issued under an indenture to be entered into between us and Wells Fargo Bank, National Association, as trustee. The indenture, and any supplemental indentures thereto, will be subject to, and governed by, the Trust Indenture Act of 1939, as amended. The following description of general terms and provisions relating to the debt securities and the indenture under which the debt securities will be issued is a summary only and therefore is not complete and is subject to, and qualified in its entirety by reference to, the terms and provisions of the indenture. The form of the indenture has been filed with the SEC as an exhibit to the registration statement, of which this prospectus forms a part, and you should read the indenture for provisions that may be important to you. For more information on how you can obtain a copy of the form of the indenture, see “Where You Can Find More Information.”

Capitalized terms used in this section and not defined herein have the meanings specified in the indenture. When we refer to “we,” “us,” “our,” “Conagra,” “Conagra Brands,” the “Company” or other similar terms in this section, we mean Conagra Brands, Inc. and its consolidated subsidiaries, unless we state otherwise or the context indicates otherwise.

Unless otherwise specified in a prospectus supplement, the debt securities will be our direct, unsecured obligations and will rank equally with all of our existing and future senior unsecured indebtedness senior in right of payment to all of our subordinated indebtedness.

The indenture does not limit the aggregate principal amount of debt securities that may be issued under it and provides that debt securities may be issued under it from time to time in one or more series. We may specify a maximum aggregate principal amount for the debt securities of any series.

Unless otherwise specified in the applicable prospectus supplement, the indenture does not afford the holders of the debt securities the right to require us to repurchase or redeem the debt securities in the event of a highly-leveraged transaction.

We are not obligated to issue all debt securities of one series at the same time and, unless otherwise provided in the applicable prospectus supplement, we may reopen a series, without the consent of the holders of the outstanding debt securities of that series, for the issuance of additional debt securities of that series. Additional debt securities of a particular series will have the same terms and conditions as outstanding debt securities of such series, except for the issue date and, in some cases, the public offering price and the first interest payment date, and will be consolidated with, and form a single series with, such outstanding debt securities; provided, however, that if such additional debt securities are not fungible with the outstanding debt securities of such series for U.S. federal income tax purposes, the additional debt securities will have a separate CUSIP number.

We will set forth in a prospectus supplement relating to any debt securities being offered, the aggregate principal amount and the following terms of the debt securities, if applicable:

The foregoing is not intended to be an exclusive list of the terms that may be applicable to any offered debt securities.

In addition, the indenture does not limit our ability to issue convertible, exchangeable or subordinated debt securities. Any conversion, exchange or subordination provisions of debt securities will be described in the relevant prospectus supplement. Such terms may include provisions for conversion or exchange, either mandatory, at the option of the holder or at our option, in which case the number of shares of common stock or other securities to be received by the holders of debt securities would be calculated as of a time and in the manner stated in the prospectus supplement.

We may issue debt securities that provide for an amount less than their stated principal amount to be due and payable upon declaration of acceleration of their maturity pursuant to the terms of the indenture. We will provide you with information on the U.S. federal income tax considerations and other special considerations applicable to any of these debt securities in the applicable prospectus supplement.

If we denominate the purchase price of any of the debt securities in a foreign currency or currencies or a foreign currency unit or units, or if the principal of and any premium and interest on any series of debt securities is payable in a foreign currency or currencies or a foreign currency unit or units, we will provide you with information on the restrictions, elections, general tax considerations, specific terms and other information with respect to that issue of debt securities and such foreign currency or currencies or foreign currency unit or units in the applicable prospectus supplement.

Debt securities may be transferred or exchanged at the office of the registrar or co-registrar designated by us.

We will not impose a service charge for any transfer or exchange, but we may require holders to pay any tax or other governmental charges associated with any transfer or exchange.

In the event of any redemption of debt securities of any series, we will not be required to:

We may initially appoint the trustee as the registrar. Any transfer agent, in addition to the registrar initially designated by us, will be named in the prospectus supplement. We may designate additional transfer agents or change transfer agents or change the office of the transfer agent. However, we will be required to maintain a transfer agent in each place of payment for the debt securities of each series.

The debt securities of any series may be represented, in whole or in part, by one or more global securities. Each global security will:

As long as the depositary, or its nominee, is the registered owner of a global security, the depositary or nominee will be considered the sole owner and holder of the debt securities represented by the global security for all purposes under the indenture. Except in the above limited circumstances, owners of beneficial interests in a global security:

Payments on a global security will be made to the depositary or its nominee as the holder of the global security. Some jurisdictions have laws that require that certain purchasers of securities take physical delivery of such securities in definitive form. These laws may impair the ability to transfer beneficial interests in a global security.

Institutions that have accounts with the depositary or its nominee are referred to as “participants.” Ownership of beneficial interests in a global security will be limited to participants and to persons that may hold beneficial interests through participants. The depositary will credit, on its book-entry registration and transfer system, the respective principal amounts of debt securities represented by the global security to the accounts of its participants. Each person owning a beneficial interest in a global security must rely on the procedures of the depositary (and, if such person is not a participant, on procedures of the participant through which such person owns its interest) to exercise any rights of a holder under the indenture.

Ownership of beneficial interests in a global security will be shown on and effected through records maintained by the depositary, with respect to participants’ interests, or by any participant, with respect to interests of persons held by participants on their behalf. Payments, transfers and exchanges relating to beneficial interests in a global security will be subject to policies and procedures of the depositary. The depositary policies

and procedures may change from time to time. Neither we nor the trustee will have any responsibility or liability for the depositary’s acts or omissions or any participant’s records with respect to beneficial interests in a global security.

The provisions of this subsection will apply to the debt securities unless otherwise indicated in the prospectus supplement. Payment of interest on a debt security on any interest payment date will be made to the person in whose name the debt security is registered at the close of business on the regular record date. Payment on debt securities of a particular series will be payable at the office of a paying agent or paying agents designated by us. However, at our option, we may pay interest by mailing a check to the record holder.

We may also name any other paying agents in the prospectus supplement. We may designate additional paying agents, change paying agents or change the office of any paying agent. However, we will be required to maintain a paying agent in each place of payment for the debt securities of a particular series.

Subject to any applicable abandoned property law, all moneys paid by us to a paying agent for payment on any debt security that remain unclaimed at the end of two years after such payment was due will be repaid to us. Thereafter, the holder may look only to us for such payment.

Except as otherwise set forth in the applicable prospectus supplement, we may not merge or consolidate with or into any other person, in a transaction in which we are not the surviving corporation, or sell, convey, transfer, lease or otherwise dispose of all or substantially all of the properties and assets of us and our subsidiaries, taken as a whole, to any person, unless:

In the event of the above transaction, if there is a successor or transferee, then the successor or transferee will expressly assume all of our obligations under the indenture and automatically be substituted for us in the indenture and as issuer of the debt securities and may exercise every right and power of ours under the indenture with the same effect as if such successor or transferee had been named in our place in the indenture; provided, however, that the predecessor company will not be relieved of the obligation to pay principal and interest on the debt securities except in the case of a sale of all of the assets of us and our subsidiaries.

Event of default means, with respect to any series of debt securities, any of the following:

We will promptly deliver to the trustee written notice of any event which with the giving of notice and the lapse of time would become a covenant event of default, or any other event of default provided with respect to debt securities of that series that is described in the applicable prospectus supplement, along with a description of the status and what action we are taking or propose to take with respect to such event of default.

No event of default with respect to a particular series of debt securities (except as to certain events of bankruptcy, insolvency or reorganization) necessarily constitutes an event of default with respect to any other series of debt securities. The occurrence of an event of default may constitute an event of default under our bank credit agreements in existence from time to time. In addition, the occurrence of certain events of default or an acceleration under the indenture may constitute an event of default under certain of our other indebtedness outstanding from time to time.

If an event of default (other than an event of default resulting from certain events of bankruptcy, insolvency or reorganization of our company) with respect to debt securities of any series at the time outstanding occurs and is continuing, then the trustee or the holders of not less than 25% in aggregate principal amount of the outstanding debt securities of that series may, by a notice in writing to us (and to the trustee if given by the holders), declare to be due and payable immediately the principal (or, if the debt securities of that series are discount securities, that portion of the principal amount as may be specified in the terms of that series) of, and accrued and unpaid interest, if any, on all debt securities of that series. In the case of an event of default resulting from certain events of bankruptcy, insolvency or reorganization of our company, the principal (or such specified amount) of and accrued and unpaid interest, if any, on all outstanding debt securities will become and be immediately due and payable without any declaration or other act on the part of the trustee or any holder of outstanding debt securities. At any time after a declaration of acceleration with respect to debt securities of any series has been made, the holders of a majority in aggregate principal amount of the outstanding debt securities of that series may rescind and annul the acceleration if the rescission and annulment would not conflict with any judgment or decree already rendered and if all events of default with respect to that series, other than the non-payment of principal and interest, if any, with respect to debt securities of that series that has become due and payable solely because of the acceleration, have been cured or waived and all sums paid or advanced by the trustee and the reasonable compensation, expenses and disbursements of the trustee and its agents and counsel have been paid as provided in the indenture.

The indenture provides that the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request of any holder of outstanding debt securities, unless the trustee receives security or indemnity satisfactory to it against any loss, liability or expense. Subject to certain rights of the trustee, the holders of a majority in principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to the debt securities of that series.

No holder of any debt security of any series will have any right to institute any proceeding, judicial or otherwise, with respect to the indenture or for the appointment of a receiver or trustee, or for any remedy under the indenture, unless:

Notwithstanding the foregoing, the holder of any debt security will have an absolute and unconditional right to receive payment of the principal of, and premium and any interest on, that debt security on or after the due dates expressed in that debt security and to institute suit for the enforcement of such payment.

The indenture requires us, within 120 days after the end of our fiscal year, to furnish to the trustee a statement as to compliance with the indenture. The indenture provides that the trustee may withhold notice to the holders of debt securities of any series of any default or event of default (except in payment on any debt securities of that series) with respect to debt securities of that series if it in good faith determines that withholding notice is in the interest of the holders of those debt securities.

We may amend or modify the indenture without the consent of any holder of debt securities of the series affected by the modifications or amendments in order to:

Other amendments and modifications of the indenture or the debt securities issued may be made with the consent of the holders of at least a majority of the aggregate principal amount of the outstanding debt securities

of the affected series, and our compliance with any provision of the indenture with respect to the debt securities may be waived by written notice to the trustee by the holders of a majority of the aggregate principal amount of the outstanding debt securities of the affected series. However, no modification or amendment may, without the consent of the holder of each outstanding debt security of the affected series:

Except for certain specified provisions, the holders of at least a majority in principal amount of the outstanding debt securities of an affected series may, on behalf of the holders of all debt securities of such series, waive our compliance with provisions of the indenture. Prior to the acceleration of the maturity of the debt securities of any series pursuant to the terms of the indenture, the holders of a majority in aggregate principal amount of the outstanding debt securities of such series may, on behalf of the holders of all the debt securities of such series, waive any past default under the indenture with respect to such debt securities and its consequences, except (i) a default with respect to such series in the payment of the principal of, or premium or any interest on, the debt securities of such series or (ii) a default or event of default in respect of a covenant or provision that cannot be modified or amended without the consent of all of the holders of the outstanding debt securities of the affected series.

Defeasance of Debt Securities and Certain Covenants in Certain Circumstances

Legal Defeasance. The indenture provides that, in certain circumstances, we may be discharged from any and all obligations in respect of the debt securities of any series (except for certain obligations to register the transfer or exchange of debt securities, to replace stolen, lost or mutilated debt securities, and to maintain paying agencies and certain provisions relating to the treatment of funds held by paying agents). We will be so discharged upon the deposit with the trustee, in trust, of money and/or U.S. government obligations in such amounts as will be sufficient, without consideration of any reinvestment of interest, in the written opinion of a nationally recognized firm of independent public accountants, a nationally recognized investment bank or a nationally recognized appraisal firm to pay and discharge each installment of principal, premium and interest in accordance with the terms of the indenture and the debt securities of that series.

This discharge may occur only if, among other things, we have delivered to the trustee an opinion of counsel stating that we have received from, or there has been published by, the United States Internal Revenue Service a ruling or, since the date of execution of the indenture, there has been a change in the applicable U.S. federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the beneficial owners of the debt securities of the applicable series will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the deposit, defeasance and discharge and will be subject to U.S. federal income tax on the same amounts and in the same manner and at the same times as would have been the case if the deposit, defeasance and discharge had not occurred.

Defeasance of Certain Covenants. The indenture provides that, upon compliance with certain conditions, we may be released from our obligation to comply with certain covenants set forth in the indenture and any

supplemental indenture, and any failure to comply with those covenants will not constitute a default or an event of default with respect to the debt securities of the applicable series, or covenant defeasance. If we exercise our covenant defeasance option with respect to a series of debt securities, payment of such debt securities may not be accelerated because of an event of default related to certain events of bankruptcy, insolvency or reorganization of our significant subsidiaries.

The indenture and the debt securities will be governed by, and construed in accordance with, the internal laws of the State of New York.

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

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

Some or all of the securities that we offer though this prospectus may be new issues of securities with no established trading market. Any underwriters to whom we sell our securities for public offering and sale may make a market in those securities, but they will not be obligated to do so and they may discontinue any market making at any time without notice. Accordingly, we cannot assure you of the liquidity of, or continued trading markets for, any securities that we offer.

If dealers are used in the sale of the securities, we will sell the securities to them as principals. They may then resell the securities to the public at varying prices determined by the dealers at the time of resale. We will include in the prospectus supplement the names of the dealers and the terms of the transaction.

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

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

Offered securities may also be offered and sold, if so indicated in the applicable prospectus supplement, in connection with a remarketing upon their purchase, in accordance with a redemption or repayment pursuant to

their terms, or otherwise, by one or more remarketing firms, acting as principals for their own accounts or as agents for us. Any remarketing firm will be identified and the terms of its agreements, if any, with us and its compensation will be described in the applicable prospectus supplement.

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

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

Unless otherwise indicated in the prospectus supplement, certain legal matters with respect to the validity of the securities will be passed upon for us by Jones Day.
