Hewlett Packard Enterprise (HPE) 424B5Prospectus supplement for primary offering

This document is in two parts. The first part is this prospectus supplement, which describes the specific terms of this offering of the notes, and also adds to and updates information contained in the accompanying prospectus and the documents incorporated by reference.

There is no existing market for the 20  notes and no active trading market for the 2024 notes may exist or be maintained. The existing 2024 notes are not listed and we will not apply for listing of any of the notes offered hereby on any securities exchange or any automated quotation system. Accordingly, there can be no assurance that trading markets for the 2024 notes will exist or will be maintained or that a trading market for the 20  notes will ever develop or will be maintained.

If an active trading market does not develop or is not maintained for a series of notes, the market price and liquidity of such notes may be adversely affected. In that case, you may not be able to sell your notes at a particular time or at a favorable price.

The notes will be obligations exclusively of Hewlett Packard Enterprise and not of any of our subsidiaries. Most of our assets are owned through our subsidiaries, and we depend on distributions of cash flow and earnings from our subsidiaries in order to meet our payment obligations under the notes and our other debt obligations. Our subsidiaries are separate legal entities that have no obligation to pay any amounts due under the notes or to make any funds available therefor, whether by dividends, loans or other payments. Except to the extent we are a creditor with recognized claims against our subsidiaries, all claims of creditors (including trade creditors) and holders of preferred stock, if any, of our subsidiaries will have priority with respect to the assets of such subsidiaries over our claims (and therefore the claims of our creditors, including holders of the notes). Consequently, the notes will be structurally subordinated to all liabilities of our existing subsidiaries and any subsidiaries that we may in the future acquire or establish.

We currently maintain investment grade credit ratings with Moody’s Investors Service, S&P Global Ratings and Fitch Ratings. Despite these investment grade credit ratings, any future downgrades could increase the cost of borrowing under any indebtedness we may incur, reduce market capacity for our commercial paper or require the posting of additional collateral under our derivative contracts. Additionally, increased borrowing costs, including those arising from a credit rating downgrade, can potentially reduce the competitiveness of our financing business. There can be no assurance that we will be able to maintain our credit ratings, and any additional actual or anticipated changes or downgrades in our credit ratings, including any announcement that our ratings are under review for a downgrade, may have a negative impact on our liquidity, capital position and access to capital markets and could affect the market value of the notes. Also, our credit ratings may not reflect the potential impact of risks related to the terms of the notes or other factors related to the value of the notes.

As of April 30, 2023, on an as adjusted basis giving effect to the issuance and sale of the notes (the “Transaction”), our total debt would have been approximately $   , and we would have had up to an expected additional $4.75 billion of borrowings available under our revolving credit facility. Despite our current level of debt, we and our subsidiaries may be able to incur significant additional debt, including secured debt, in the future.

If new debt is added to our and our subsidiaries’ current debt levels, the related risks that we and they face would be increased, and we may not be able to meet all our debt obligations, including repayment of the notes, in whole or in part.

Our ability to make payments on, and to refinance, our debt and to fund planned capital expenditures will depend on our ability to generate cash in the future and our ability to borrow under our revolving credit facility to the extent of available borrowings. This, to a certain extent, is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control. We could experience decreased revenues from our operations and could fail to generate sufficient cash to fund our liquidity needs or fail to satisfy the covenants and borrowing limitations to which we are subject under our debt instruments. We cannot assure you, however, that our business will generate sufficient cash flow from operations or that future borrowings will be available to us under the revolving credit facility or otherwise in an amount sufficient to enable us to pay our debt or to fund our other liquidity needs. We may need to refinance all or a portion of our debt on or before the maturity thereof. We cannot assure you that we will be able to refinance any of our debt on commercially reasonable terms or at all. If we cannot service our debt, we may have to take actions such as selling assets, selling equity or reducing or delaying capital expenditures, strategic acquisitions, investments and alliances. We cannot assure you that any such actions, if necessary, could be effected on commercially reasonable terms or at all.

Any default under the agreements governing our debt, including a default under our revolving credit facility, that is not waived by the required lenders or holders of such debt, and the remedies sought by the holders of such debt could prevent us from paying principal and interest on the notes and substantially decrease the market value of the notes. If we are unable to generate sufficient cash flow or are otherwise unable to obtain funds necessary to meet required payments or principal and interest on our debt, or if we otherwise fail to comply with the various covenants in the agreements governing our debt, including the covenants contained in our revolving credit facility, we would be in default under the terms of the agreements governing such debt.

Under the indenture that will govern the notes, upon the occurrence of a Change of Control Repurchase Event in respect of a series of notes, we will be required to offer to repurchase all outstanding notes of such series at 101% of the principal amount thereof plus accrued and unpaid interest to the date of repurchase. However, we may not have sufficient funds at the time of the Change of Control Repurchase Event to make the required repurchase of such series of notes. Our failure to make or complete a change of control offer would place us in default under the indenture that will govern the notes. However, we cannot assure you that we would be able to repay such debt at such time.

We have the right to redeem some or all of the notes prior to maturity. We may redeem the notes at times when prevailing interest rates may be relatively low. Accordingly, you may not be able to reinvest the redemption proceeds in comparable securities at effective interest rates as high as those of the notes.

We estimate that the net proceeds from this offering will be approximately $   , after deducting the underwriting discounts and the estimated offering expenses payable by us. We intend to use the net proceeds from this offering, together with cash on hand, to refinance upcoming debt maturities and for general corporate purposes.

Our management will retain broad discretion as to the allocation of the net proceeds from this offering. Until we use the net proceeds of this offering, we may invest the net proceeds of this offering in short term, interest bearing investments.

The following table sets forth our cash and capitalization as of April 30, 2023, both actual and adjusted to give effect to this offering of the notes after deducting underwriting discounts and commissions and estimated offering expenses payable by us. See “Use of Proceeds” in this prospectus supplement.

You should read this table in conjunction with our consolidated financial statements incorporated by reference herein.

We are issuing $    aggregate principal amount of 2024 notes. The 2024 notes will mature on on October 1, 2024. Interest on the 2024 notes will accrue at the rate of 5.900% per annum.

We are issuing $    aggregate principal amount of 20   notes. The 20   notes will mature on    . Interest on the 20   notes will accrue at the rate of   % per annum.

We previously issued $1,300,000,000 aggregate principal amount of 5.900% Notes due 2024 (the “existing 2024 notes”), all of which will remain outstanding following this offering. The existing 2024 notes were issued under the Base Indenture, as supplemented by the Nineteenth Supplemental Indenture, dated as of March 21, 2023, between the Company and the Trustee (the “Nineteenth Supplemental Indenture”). The 2024 notes will form a part of the series of the existing 2024 notes and will have the same terms as the existing 2024 notes other than the issue date. The 2024 notes will have the same CUSIP number as the existing 2024 notes and will trade interchangeably with the existing 2024 notes immediately upon settlement. The 2024 notes and the existing 2024 notes will constitute a single series under the Indenture for all purposes. Upon issuance of the 2024 notes, the aggregate principal amount outstanding of our 5.900% Senior Notes due 2024 will be $   . Unless the context requires otherwise, for all purposes of the Indenture and this “Description of the Notes,” references to the notes include the 2024 notes offered hereby and the existing 2024 notes.

The notes will be our senior unsecured obligations and will rank on the same basis with all of our other senior unsecured indebtedness from time to time outstanding. Each series of the notes will be a separate series of senior debt securities under the Indenture. The Indenture will not limit the aggregate principal amount of securities that may be issued under the Indenture. Without the consent of the holders, we may increase the aggregate principal amount of the notes of any series in the future on the same terms and conditions (except for issuance date, price and, in some cases, the initial interest payment date) as the notes of that series being offered hereby. Securities may be issued under the Indenture from time to time as a single series or in two or more separate series up to the aggregate principal amount authorized by us from time to time for the notes of any series. Additional notes of a series may only bear the same CUSIP number if they would be fungible for United States federal income tax purposes with the existing notes of that series.

If the maturity date of a series of notes falls on a day that is not a Business Day, payment of principal, premium, if any, and interest for such notes then due will be paid on the next Business Day. No interest on that payment will accrue from and after the maturity date. Payments of principal, premium, if any, and interest on the notes will be made by us through the Trustee to the depositary. Each series of notes will be issued in the form of one or more fully registered global securities in denominations of $2,000 and integral multiples of $1,000 in excess thereof. See “Description of the Debt Securities—Global Securities” in the accompanying prospectus.

We will make interest payments on our 2024 notes semi-annually in arrears on April 1 and October 1 of each year, beginning on October 1, 2023 and on our 20   notes semi-annually in arrears on     and     of

Prior to the Par Call Date (in the case of the 20   notes) or the maturity date (in the case of the 2024 notes), each series of notes will be redeemable in whole at any time or in part from time to time, at our option, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) as calculated by us equal to the greater of:

On or after the Par Call Date, we may redeem the 20   notes, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the notes being redeemed, plus accrued and unpaid interest thereon to, but not including, the redemption date.

Any redemption or notice may, at our discretion, be subject to one or more conditions precedent, including, but not limited to, completion or occurrence of a related transaction or event. At our discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the redemption date, or by the redemption date as so delayed. We will provide written notice to the Trustee prior to the close of business two business days prior to the redemption date or such shorter time as may be acceptable to the Trustee, if any such redemption has been rescinded or delayed, and upon receipt the Trustee will provide such notice to each holder of the notes to be redeemed in the same manner in which the notice of redemption was given.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the redemption date to each holder of notes to be redeemed, with a copy to the trustee.

In the case of a partial redemption of a series of notes, selection of certificated notes of such series for redemption will be made by lot. No notes of a principal amount of $2,000 or less will be redeemed in part. If any certificated note of a series is to be redeemed in part only, the notice of redemption that relates to such note of such series will state the portion of the principal amount of the note of such series to be redeemed. A new certificated note of such series in a principal amount equal to the unredeemed portion of such note of such series will be issued in the name of the holder of such note upon surrender for cancellation of the original certificated note. For so long as the notes are held by DTC (or another depositary), the redemption of the notes shall be done in accordance with the policies and procedures of DTC (or such other depositary), which may be made on a pro rata pass-through distribution of principal basis.

Unless we default in payment of the redemption price, on and after the redemption date of notes of a series, interest will cease to accrue on such notes or any portions thereof called for redemption.

If a Change of Control Repurchase Event with respect to a series of notes occurs, unless we have exercised our right to redeem the notes of such series as described under the caption “—Redemption—Optional Redemption,” we will be required to make an offer to each holder of notes of such series to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that holder’s notes of such series at a repurchase price in cash equal to 101% of the aggregate principal amount of notes repurchased plus any accrued and unpaid interest on the notes repurchased to the date of purchase. Within 30 days following any Change of Control Repurchase Event or, at our option, prior to any Change of Control, but after the public announcement of the transaction or event that constitutes or may constitute the Change of Control, we will send a notice to each holder to which we are required to make a repurchase offer as described above, with a copy to the Trustee, describing the transaction or event that constitutes or may constitute the Change of Control Repurchase Event and offering to repurchase the notes of the applicable series on the payment date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed. The notice may, if sent prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Repurchase Event occurring on or prior to the payment date specified in the notice.

We will be required to 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 Repurchase Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Repurchase Event provisions of the notes, we will be required to comply with the applicable securities laws and regulations and will not be deemed to have breached our obligations under the Change of Control Repurchase Event provisions of the notes by virtue of any such compliance.

The paying agent will promptly send to each holder of notes properly tendered and not withdrawn the purchase price for such notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each holder a new note equal in principal amount to any unpurchased portion of any such notes surrendered; provided that each new note will be in a minimum principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.

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

We could, in the future, enter into certain transactions, including acquisitions, refinancings or other recapitalizations, that would not constitute a Change of Control, but that could increase the amount of indebtedness outstanding at such time or otherwise materially adversely affect our capital structure or credit ratings.

The Change of Control purchase feature of the notes may, in certain circumstances, make more difficult or discourage a takeover of us and, thus, the removal of incumbent management. The Change of Control purchase feature, however, is not the result of management’s knowledge of any specific effort to accumulate shares of our

Hewlett Packard Enterprise or any of its affiliates may at any time and from time to time purchase notes in the open market or otherwise.

The notes will be unsecured and unsubordinated obligations of Hewlett Packard Enterprise and will rank equally with all its other existing and future unsecured and unsubordinated indebtedness, including under its existing revolving credit facility. Most of our assets are owned through our subsidiaries, and we depend on distributions of cash flow and earnings from our subsidiaries in order to meet our payment obligations under the notes and our other debt obligations. These subsidiaries are separate and distinct legal entities and have no obligation to pay any amounts due on our debt securities, including the notes, or to provide us with funds for our payment obligations, whether by dividends, distributions, loans or otherwise. As a result, the notes will be structurally subordinated to the liabilities of our subsidiaries, including trade payables. In addition, provisions of applicable law, such as those limiting the legal sources of dividends, could limit the ability of our subsidiaries to make payments or other distributions to us and our subsidiaries could agree to contractual restrictions on their ability to make distributions. As of April 30, 2023, our consolidated subsidiaries had approximately $3.6 billion of indebtedness, excluding intercompany loans. Our indebtedness as of April 30, 2023, on an as adjusted basis giving effect to the Transaction, would have been approximately $   .

Hewlett Packard Enterprise will not issue, incur, create, assume or guarantee, and will not permit any Restricted Subsidiary to issue, incur, create, assume or guarantee, any Secured Debt without in any such case effectively providing concurrently with such issuance, incurrence, creation, assumption or guarantee of any such Secured Debt, or the grant of a Mortgage with respect to any such indebtedness, that the notes (together with, if Hewlett Packard Enterprise shall so determine, any other indebtedness of or guarantee by Hewlett Packard Enterprise or such Restricted Subsidiary ranking equally with the notes and then existing or thereafter created) shall be secured equally and ratably with (or, at the option of Hewlett Packard Enterprise, prior to) such Secured Debt. The foregoing restriction with respect to Secured Debt, however, will not apply to:

Notwithstanding the restrictions outlined in the preceding paragraph, Hewlett Packard Enterprise or any Restricted Subsidiary will be permitted to issue, incur, create, assume or guarantee Secured Debt, which would otherwise be subject to such restrictions, without equally and ratably securing the notes, provided that after giving effect thereto, the aggregate amount of all Secured Debt (not including Mortgages permitted under clauses (1) through (11) above) does not exceed the greater of $500 million and 10% of the Consolidated Net Tangible Assets of Hewlett Packard Enterprise as most recently determined on or prior to such date.

Hewlett Packard Enterprise will not, nor will it permit any Restricted Subsidiary to, enter into any Sale and Lease-Back Transaction with respect to any Principal Property, other than any such transaction involving a lease for a term of not more than three years or any such transaction between Hewlett Packard Enterprise and a Restricted Subsidiary or between Restricted Subsidiaries, unless: (1) Hewlett Packard Enterprise or such Restricted Subsidiary would be entitled to incur indebtedness secured by a Mortgage on the Principal Property involved in such transaction at least equal in amount to the Attributable Debt with respect to such Sale and Lease-Back Transaction, without equally and ratably securing the notes as described above under “Limitation on Liens”; or (2) Hewlett Packard Enterprise shall apply an amount equal to the greater of the net proceeds of such

Notwithstanding the restrictions outlined in the preceding paragraph, Hewlett Packard Enterprise or any Restricted Subsidiary will be permitted to enter into Sale and Lease-Back Transactions which would otherwise be subject to such restrictions, without applying the net proceeds of such transactions in the manner set forth in clause (2) of the preceding paragraph, provided that after giving effect thereto, the aggregate amount of such Sale and Lease-Back Transactions, together with the aggregate amount of all Secured Debt not permitted by clauses (1) through (11) under “Limitation on Liens” above, does not exceed the greater of $500 million and 10% of Consolidated Net Tangible Assets of Hewlett Packard Enterprise as most recently determined on or prior to such date.

Hewlett Packard Enterprise shall not consolidate with or merge into any other Person (in a transaction in which Hewlett Packard Enterprise is not the surviving corporation) or convey, transfer or lease its properties and assets substantially as an entirety to any Person, unless:

If an Event of Default, other than an Event of Default described in clause (4) above, shall occur and be continuing, either the Trustee or the holders of at least 25% in aggregate principal amount of the outstanding

After acceleration, the holders of a majority in aggregate principal amount of the outstanding notes of that series, under certain circumstances, may rescind and annul such acceleration if all Events of Default, other than the non-payment of accelerated principal, or other specified amount, have been cured or waived.

Subject to its required standard of care during an event of default, the Trustee will not be obligated to exercise any of its rights or powers at the request of the holders unless the holders shall have offered to the Trustee indemnity satisfactory to it. Generally, the holders of a majority in aggregate principal amount of the outstanding notes 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 that series.

A holder will not have any right to institute any proceeding under the Indenture, or for the appointment of a receiver or a trustee, or for any other remedy under the Indenture, unless:

Holders may, however, sue to enforce the payment of principal, premium or interest on any series of notes on or after the due date without following the procedures listed in (1) through (3) above.

We will furnish the Trustee with an annual statement by our officers as to whether or not we are in default in the performance of the Indenture and, if so, specifying all known defaults. We will also notify the Trustee promptly upon our becoming aware of a default.

The provisions of the Indenture relating to modifications and amendments to and waivers under the Indenture described under the caption “Description of the Debt Securities—Modification and Waiver” in the accompanying prospectus will apply to the notes.

To make either of the above elections, we must deposit in trust with the Trustee cash, U.S. government obligations or a combination thereof sufficient to pay in full the principal, interest and any premium on the debt securities. As a condition to either of the above elections, we must deliver to the Trustee an opinion of counsel that the holders of the debt securities will not recognize income, gain or loss for United States federal income tax purposes as a result of the deposit and related defeasance. In addition, we are required to deliver to the Trustee an officers’ certificate stating that such deposit was not made by us with the intent of preferring the holders over other creditors of ours or with the intent of defeating, hindering, delaying or defrauding creditors of ours or others.

If any of the above events occur, the holders of the debt securities of the series will not be entitled to the benefits of the Indenture, except for registration of transfer and exchange of debt securities, replacement of lost, stolen or mutilated debt securities and, if applicable, conversion and exchange of debt securities.

The Indenture will limit the right of the Trustee, if it becomes our creditor, to obtain payment of claims or secure its claims.

The Trustee is permitted to engage in certain other transactions. If the Trustee acquires any conflicting interest, however, and there is a default under the notes of any series for which it is acting as trustee, the Trustee must eliminate the conflict or resign. Affiliates of The Bank of New York Mellon Trust Company, National Association have performed and continue to perform services for us or our affiliates in the normal course of business.

The provisions described under the caption “Description of the Debt Securities—Payment and Paying Agents” in the accompanying prospectus will apply to the notes.

The provisions described under the caption “Description of the Debt Securities—Exchange and Transfer” in the accompanying prospectus will apply to the notes.

“Attributable Debt” means, in respect of a Sale and Lease-Back Transaction involving a Principal Property, at the time of determination, the lesser of: (a) the fair value of such property (as determined in good faith by the Board of Directors); or (b) the present value of the total net amount of rent required to be paid under such lease during the remaining term thereof (including any renewal term or period for which such lease has been extended), discounted at the rate of interest set forth or implicit in the terms of such lease or, if not practicable to

“Below Investment Grade Rating Event” means, with respect to a series of the notes, the rating on such notes is lowered by each of the Rating Agencies, and such notes are rated below Investment Grade by each of the Rating Agencies, within 60 days from the earlier of (1) the date of the public notice of an arrangement that could result in a Change of Control or (2) the occurrence of a Change of Control (which period shall be extended so long as the rating of such notes is under publicly announced consideration for possible downgrade by any of the Rating Agencies).

“Board of Directors” means either the Board of Directors of Hewlett Packard Enterprise or any duly authorized committee empowered by that Board or the Executive Committee thereof to act with respect to the Indenture.

Notwithstanding the foregoing, a transaction will not be considered to be a Change of Control under clause (2) above if (a) we become a direct or indirect wholly owned subsidiary of a holding company and (b) (y) 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 (z) immediately following that transaction, no person (as that term is used in Section 13(d)(3) of the Exchange Act), other than a holding company satisfying the requirements of this sentence, is the beneficial owner, directly or indirectly, of more than 50% of the Voting Stock of the holding company.

“Change of Control Repurchase Event” means the occurrence of both a Change of Control and a Below Investment Grade Rating Event.

“Continuing Directors” means, as of any date of determination, any member of our Board of Directors who (1) was a member of such Board of Directors on the Issue Date; or (2) was nominated for election, elected or appointed to such Board of Directors with the approval of a majority of the Continuing Directors who were members of such Board of Directors at the time of such nomination, election or appointment (either by a specific vote or by approval by such Continuing Directors of our proxy statement in which such member was named as a nominee for election as a director).

Under a Delaware Chancery Court interpretation of the foregoing definition of “Continuing Directors,” our Board of Directors could approve, for purposes of such definition, a slate of stockholder-nominated directors without endorsing them or while simultaneously recommending and endorsing its own slate instead. Accordingly, under such interpretation, our Board of Directors could approve a slate of directors that includes a majority of dissident directors nominated pursuant to a proxy contest, and the ultimate election of such dissident slate would not constitute a “Change of Control Repurchase Event” that would trigger a holder’s right to require us to repurchase the holder’s notes as described above.

“Investment Grade” means a rating of BBB- or better by Fitch (or its equivalent under any successor rating categories of Fitch), Baa3 or better by Moody’s (or its equivalent under any successor rating categories of Moody’s) and a rating of BBB- or better by S&P (or its equivalent under any successor rating categories of S&P) or the equivalent investment grade credit rating from any additional Rating Agency or Rating Agencies selected by us.

“Nonrecourse Obligation” means indebtedness or other obligations substantially related to (i) the acquisition of assets not previously owned by Hewlett Packard Enterprise or any Restricted Subsidiary or (ii) the financing of a project involving the development or expansion of properties Hewlett Packard Enterprise or any Restricted Subsidiary, as to which the obligee with respect to such indebtedness or obligation has no recourse to Hewlett Packard Enterprise or any Restricted Subsidiary or any assets of Hewlett Packard Enterprise or any Restricted Subsidiary other than the assets which were acquired with the proceeds of such transaction or the project financed with the proceeds of such transaction (and the proceeds thereof).

“Person” means any individual, corporation, limited liability company, partnership, joint venture, trust, unincorporated organization or government or any agency or political subdivision thereof or any other entity of any kind.

“Principal Property” means the land, land improvements, buildings and fixtures owned by us or a Restricted Subsidiary located in the United States that constitutes our principal corporate office, any manufacturing plant or any manufacturing facility and has a book value in excess of 0.75% of our Consolidated Net Tangible Assets as of the determination date. Principal Property does not include any property that our Board of Directors has determined not to be of material importance to the business conducted by our subsidiaries and us, taken as a whole.

“Restricted Subsidiary” means any Subsidiary which owns any Principal Property; provided, however, that the term “Restricted Subsidiary” shall not include (a) any Subsidiary which is principally engaged in financing receivables, or which is principally engaged in financing Hewlett Packard Enterprise’s operations outside the United States of America; or (b) any Subsidiary less than 80% of the voting stock of which is owned, directly or indirectly, by Hewlett Packard Enterprise or by one or more other Subsidiaries, or by Hewlett Packard Enterprise and one or more other Subsidiaries, if the common stock of such Subsidiary is traded on any national securities exchange or quoted on the Nasdaq National Market or in the over-the-counter market.

“Sale and Lease-Back Transaction” means any arrangement with any person providing for the leasing by Hewlett Packard Enterprise or any Restricted Subsidiary of any Principal Property which property has been or is to be sold or transferred by Hewlett Packard Enterprise or such Restricted Subsidiary to such person.

“Secured Debt” means any debt for borrowed money secured by a Mortgage upon any Principal Property of Hewlett Packard Enterprise or any Restricted Subsidiary or upon any shares of stock or indebtedness of any Restricted Subsidiary (whether such Principal Property, shares or indebtedness are now existing or owed or hereafter created or acquired).

“Subsidiary” means a corporation of which at least 66 2/3% of the outstanding voting stock of such corporation is at the time owned, directly or indirectly, by Hewlett Packard Enterprise or by one or more other Subsidiaries, or by Hewlett Packard Enterprise and one or more other Subsidiaries, and the accounts of which are consolidated with those of Hewlett Packard Enterprise in its most recent consolidated financial statements in accordance with generally accepted accounting principles. For the purposes of this definition, “voting stock” means stock which ordinarily has voting power for the election of directors, whether at all times or only so long as no senior class of stock has such voting power by reason of any contingency.

“Treasury Rate” means, with respect to any redemption date for any notes of a series, the yield determined by us in accordance with the following two paragraphs.

The Treasury Rate applicable to such redemption shall be determined by us after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities—Treasury constant maturities—Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the applicable Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the Par Call Date (in the case of the 20   notes) or the maturity date of the notes (in the case of the 2024 notes) (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields—one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life—and shall interpolate to the Par Call Date (in the case of the 20   notes) or the maturity date of the notes (in the case of the 2024 notes) on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third business day preceding the redemption date H.15 TCM is no longer published, we shall calculate the Treasury Rate applicable to such redemption based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date

Our actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error. We will notify the trustee of the redemption price promptly after the calculation thereof and the trustee shall have no duty to determine, or verify the calculation of, the redemption price.

“Voting Stock” means, with respect to any person as of any date, capital stock of any class or kind the holders of which are ordinarily, in the absence of contingencies, entitled to vote for the election of directors (or persons performing similar functions) of such person, even if the right so to vote has been suspended by the happening of such a contingency.

We have obtained the information in this section or in the accompanying prospectus concerning The Depository Trust Company, Clearstream Banking, société anonyme and Euroclear Bank S.A./N.V., as operator of the Euroclear System and their book-entry systems and procedures from sources that we believe to be reliable. We take no responsibility for an accurate portrayal of this information. In addition, the description of the clearing systems in this section reflects our understanding of the rules and procedures of DTC, Clearstream and Euroclear as they are currently in effect. Those systems could change their rules and procedures at any time.

if they are participants in such systems, or indirectly through organizations which are participants in such systems. Clearstream and Euroclear will hold interests on behalf of their participants through customers’ securities accounts in Clearstream’s and Euroclear’s names on the books of their respective depositaries, which in turn will hold such interests in customers’ securities accounts in the depositaries’ names on the books of the depositary.

Clearstream has advised us that it is a limited liability company organized under Luxembourg law. Clearstream holds securities for its participating organizations, referred to in this prospectus supplement as Clearstream participants, and facilitates the clearance and settlement of securities transactions between Clearstream

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

Euroclear advises that it was created in 1968 to hold securities for its participants and to clear and settle transactions between Euroclear participants through simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of certificates and any risk from lack of simultaneous transfers of securities and cash. Euroclear provides various other services, including securities lending and borrowing and interfaces with domestic markets in several countries.

Euroclear is operated by Euroclear Bank S.A./N.V., referred to in this prospectus supplement in such role as the Euroclear operator, under contract with Euroclear Clearance Systems S.C., a Belgian cooperative corporation, referred to in this prospectus supplement as the cooperative. All operations are conducted by Euroclear Bank S.A./N.V., and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with Euroclear Bank, not the cooperative. The cooperative establishes policy for Euroclear on behalf of Euroclear participants. Euroclear participants include banks (including central banks), securities brokers and dealers and other professional financial intermediaries and may include the underwriters (“Euroclear participants”). Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear participant, either directly or indirectly.

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

Distributions with respect to beneficial interests in the notes held through Euroclear will be credited to the cash accounts of Euroclear participants in accordance with the Euroclear Terms and Conditions, to the extent received by the Euroclear Bank and by Euroclear.

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

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

Although the depositary, Clearstream and Euroclear have agreed to the foregoing procedures in order to facilitate transfers of notes among participants of the depositary, Clearstream and Euroclear, they are under no obligation to perform or continue to perform such procedures and such procedures may be discontinued at any time.

The following summary describes certain U.S. federal income tax consequences of the acquisition, ownership and disposition of the notes. This summary is based on the Internal Revenue Code of 1986, as amended (the “Code”) and U.S. Treasury regulations promulgated thereunder, rulings and judicial decisions as of the date hereof, all of which may be changed, possibly with retroactive effect. This summary also assumes that a “substantial amount” of the notes, within the meaning of Treasury Regulation Section 1.1273-2(a)(1), are deemed to be issued for money.

This summary applies to you only if you acquire the notes for cash in this offering at the “initial offering price” and hold the notes as capital assets within the meaning of Section 1221 of the Code.

This summary is for general information only and does not address all aspects of U.S. federal income taxation that may be relevant to you in light of your particular circumstances, and it does not address state, local, non-U.S., alternative minimum or non-income tax considerations that may be applicable to you. Further, this summary does not deal with holders that may be subject to special tax rules, including, but not limited to, insurance companies; tax-exempt entities; banks and other financial institutions; thrifts; regulated investment companies; real estate investment trusts; dealers in securities or currencies; U.S. Holders (as described below) whose functional currency is not the U.S. dollar; certain U.S. expatriates; holders who hold the notes as a hedge against currency risks or as part of a straddle, synthetic security, conversion transaction or other integrated transaction for U.S. federal income tax purposes; controlled foreign corporations; foreign personal holding companies; passive foreign investment companies; traders in securities that elect to use a mark-to-market method of accounting; pass-through entities (or owners in pass-through entities); persons who hold notes in retirement plans or tax-deferred accounts; persons subject to special tax accounting rules under Section 451(b) of the Code or persons who hold existing notes issued by us that are being redeemed in any substantially contemporaneous Transaction. You should consult your own tax advisor as to the particular tax consequences to you of acquiring, holding or disposing of the notes.

For purposes of this summary, a “U.S. Holder” is a beneficial owner of a note that, for U.S. federal income tax purposes, is: (a) an individual citizen or resident of the United States; (b) a corporation created or organized in or under the laws of the United States or any state thereof (including the District of Columbia); (c) an estate the income of which is subject to U.S. federal income taxation regardless of its source; or (d) a trust if (i) a court within the United States is able to exercise primary supervision over the trust’s administration and one or more United States persons have the authority to control all substantial decisions of the trust or (ii) such trust has a valid election in effect under applicable Treasury regulations to be treated as a United States person.

For purposes of this summary, a “Non-U.S. Holder” is a beneficial owner of a note that is neither a U.S. Holder nor a partnership or any entity or arrangement treated as a partnership for U.S. federal income tax purposes.

If a partnership (or other entity or arrangement treated as a partnership for U.S. federal income tax purposes) is a beneficial owner of a note, the U.S. federal income tax treatment of a partner in such partnership will generally depend on the status of the partner and the activities of the partnership. If you are a partnership that beneficially owns a note or a partner in such a partnership, you should consult your own tax advisor as to the particular U.S. federal income tax consequences applicable to you of the acquisition, ownership and disposition of the notes.

We may be required, in certain circumstances, to pay amounts on the notes in addition to the stated principal amount of and interest on the notes (e.g., payments pursuant to a Change of Control Repurchase Event as described above under the heading “Description of the Notes—Repurchase at the Option of Holders on Certain Changes of Control” or payments pursuant to an optional redemption as described above under the heading “Description of the Notes—Redemption—Optional Redemption”). Although the issue is not free from doubt, we intend to take the position (and this discussion assumes) that the possibility of payment of such amounts does not result in the notes being treated as contingent payment debt instruments under the applicable Treasury Regulations.

It is anticipated, and the following discussion assumes, that the 2024 notes will be issued pursuant to a “qualified reopening” of the existing 2024 notes. Accordingly, it is anticipated that the 2024 notes will be considered to be part of the same issue, and have the same issue date and issue price, as the existing 2024 notes for U.S. federal income tax purposes.

The following discussion assumes that the notes will be issued with less than a de minimis amount (as set forth in the Code and applicable Treasury Regulations) of original issue discount. In such case, subject to the discussion below on pre-issuance accrued interest, interest on a note will generally be taxable to you as ordinary interest income as it accrues or is received by you in accordance with your regular method of accounting for U.S. federal income tax purposes.

A portion of the purchase price for the 2024 notes may be allocable to interest that accrued prior to the date the 2024 notes are purchased (“pre-issuance accrued interest”). On the first interest payment date, a portion of the interest received in an amount equal to the pre-issuance accrued interest will be treated as a return of the pre-issuance accrued interest and not as a payment of interest on the 2024 notes. The amount treated as a return of pre-issuance accrued interest is not taxable when received but reduces your tax basis in the 2024 notes by a corresponding amount. You should consult your tax advisor concerning the tax treatment of pre-issuance accrued interest.

If your initial tax basis in a note (which will generally equal the cost of the note to such holder (excluding amounts allocated to pre-issuance accrued interest)) exceeds the amount payable on the note (other than payments of stated interest), you will be treated as having acquired the notes with “bond premium” in an amount equal to such excess. You may elect to amortize such bond premium, in which case the amount required to be included in your income each year with respect to stated interest on the note will be reduced by the amount of amortizable bond premium allocable (based on the note’s yield to maturity) to that year. Any election to amortize bond premium will apply to all bonds (other than bonds the interest on which is excludable from the gross income for United States federal income tax purposes) held by you at the beginning of the first taxable year to which the election applies or thereafter acquired by you, and is irrevocable without the consent of the IRS. If you do not elect to amortize bond premium, any bond premium on a note will decrease any gain or increase any loss such holder may otherwise recognize on disposition of the note.

Upon the sale, exchange, redemption, retirement or other taxable disposition of a note, you will generally recognize gain or loss for U.S. federal income tax purposes in an amount equal to the difference between (i) the amount of the cash and the fair market value of any property you receive on the sale or other taxable disposition (less an amount attributable to any accrued but unpaid interest, which will be taxable as ordinary interest income to the extent not previously included as income), and (ii) your adjusted tax basis in the note. Your adjusted tax basis in a note will generally be equal to your cost for the note.

Certain non-corporate U.S. Holders will be subject to an additional 3.8% Medicare tax on the lesser of (1) the U.S. Holder’s “net investment income” for the relevant taxable year and (2) the excess of the U.S. Holder’s modified adjusted gross income for the taxable year over a certain threshold (which in the case of individuals will be between $125,000 and $250,000, depending on the individual’s tax return filing status). A U.S. Holder’s net investment income will generally include any income or gain recognized by such holder with respect to the notes, unless such income or gain is derived in the ordinary course of the conduct of such holder’s trade or business (other than a trade or business that consists of certain passive or trading activities). If you are a non-corporate U.S. Holder, you should consult your tax advisor regarding the applicability of the Medicare tax to your income and gains in respect of your investment in the notes.

You will also be subject to information reporting with respect to payments on the notes and proceeds from the sale or other disposition of the notes, unless you are an exempt recipient and appropriately establish that exemption.

U.S. federal backup withholding may apply to payments on the notes and proceeds from the sale or other disposition of the notes unless you provide a correct taxpayer identification number and otherwise comply with applicable requirements of the backup withholding rules or you are exempt from the backup withholding rules and appropriately establish that exemption. A U.S. Holder who does not provide the applicable withholding agent with the correct TIN may be subject to penalties imposed by the IRS.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a credit against your U.S. federal income tax liability and may entitle you to a refund, provided the required information is timely furnished to the IRS.

Subject to the discussions of backup withholding and “FATCA” below, payments of interest on the notes to you will not be subject to U.S. federal income or withholding tax, provided that:

You will satisfy these certification requirements if you certify on IRS Form W-8BEN or IRS Form W-8BEN-E, as applicable, or other suitable substitute form or other applicable form as the IRS may prescribe, under penalties of perjury, that you are not a United States person within the meaning of the Code, provide your name and address and timely deliver such form to the applicable withholding agent. If you hold a note through a foreign partnership or intermediary, you and the foreign partnership or intermediary must satisfy certification requirements of applicable Treasury regulations. Special certification rules will apply to you if you are a pass-through entity.

In addition, subject to the discussions of backup withholding and “FATCA” below, you will not be subject to U.S. federal income tax on the gain you realize (other than any amount allocable to accrued and unpaid interest, which would be treated as interest and subject to the rules discussed above in “—Interest”) on any sale, exchange or other taxable disposition of a note, unless:

If you are an individual described in the first bullet point above, you will be subject to tax on the net gain derived from the sale, exchange or other taxable disposition under regular graduated U.S. federal income tax rates in the same manner as if you were a U.S. Holder described above. If you are a foreign corporation that falls under the first bullet point above, you will be subject to tax on its net gain generally in the same manner as if you were a U.S. Holder as described above and, in addition, you may be subject to the branch profits tax equal to 30% of your effectively connected earnings and profits for that taxable year, or at such lower rate as may be specified by an applicable income tax treaty. If you are an individual described in the second bullet point above, you will be subject to a flat 30% tax on the gain derived from the sale, redemption, or other taxable disposition, which may be offset by U.S.-source capital losses, even though you are not considered a resident of the U.S.

Generally, the amount of interest paid to you and the amount of tax, if any, withheld with respect to those payments must be reported annually to the IRS and to you. Copies of the information returns reporting such interest, dividends and 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.

In general, you will not be subject to backup withholding with respect to payments of interest that we make, provided the statement described immediately below the last bullet point under “—Interest” has been received and the withholding agent does not have actual knowledge or reason to know that you are a U.S. person, as defined under the Code, that is not an exempt recipient. In addition, you will be subject to information reporting and, depending on the circumstances, backup withholding with respect to payments of the proceeds of the sale of a note within the United States or conducted through certain U.S.-related financial intermediaries, unless the statement described above has been received, and the payor does not have actual knowledge or reason to know that you are a U.S. person, as defined under the Code, that is not an exempt recipient, or you otherwise establish an exemption. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against your U.S. federal income tax liability provided the required information is timely furnished to the IRS.

Under Sections 1471 through 1474 of the Code (such Sections commonly referred to as “FATCA”), a 30% U.S. federal withholding tax will generally apply to payments of interest on the notes made to a foreign financial institution (including amounts paid to a foreign financial institution on or behalf of a holder) and certain other

While withholding under FATCA would also have applied to payments of gross proceeds from the sale or other disposition of the notes (including retirement or redemption) on or after January 1, 2019, proposed U.S. Treasury Regulations eliminate FATCA withholding on payments of gross proceeds entirely. Although these Treasury regulations are not final, the preamble to these Treasury regulations indicates that taxpayers may rely on them pending their finalization.

ERISA and the Code impose certain duties on persons who are fiduciaries of a Plan subject to Title I of ERISA or Section 4975 of the Code (an “ERISA Plan”) and prohibit certain transactions involving the assets of an ERISA Plan and its fiduciaries or other interested parties. Under ERISA and the Code, any person who exercises any discretionary authority or control over the administration of such an ERISA Plan or the management or disposition of the assets of such an ERISA Plan, or who renders investment advice for a fee or other compensation to such an ERISA Plan, is generally considered to be a fiduciary of the ERISA Plan.

In considering an investment in the notes of a portion of the assets of any Plan, a fiduciary should determine whether the investment is in accordance with the documents and instruments governing the Plan and the applicable provisions of ERISA, the Code or any Similar Law relating to a fiduciary’s duties to the Plan including, without limitation, the prudence, diversification, delegation of control and prohibited transaction provisions of ERISA, the Code and any other applicable Similar Laws.

Section 406 of ERISA and Section 4975 of the Code prohibit ERISA Plans from engaging in specified transactions involving plan assets with persons or entities who are “parties in interest” (within the meaning of Section 3(14) ERISA) or “disqualified persons” (within the meaning of Section 4975 of the Code), unless an exemption is available. A party in interest or disqualified person who engages in a non-exempt prohibited transaction may be subject to excise taxes and other penalties and liabilities under ERISA and the Code. In addition, the fiduciary of the ERISA Plan that engages in such a non-exempt prohibited transaction may be subject to penalties and liabilities under ERISA and the Code. The acquisition and/or holding of the notes by an

Because of the foregoing, the notes should not be purchased or held by any person investing “plan assets” of any Plan, unless such purchase and holding will not constitute a non-exempt prohibited transaction under ERISA and the Code or a similar violation of any applicable Similar Laws.

Accordingly, by its acceptance of a note, each purchaser and subsequent transferee of a note (or any interest therein) will be deemed to have represented and warranted that either (i) no portion of the assets used by such purchaser or transferee to acquire or hold the notes (or any interest therein) constitutes assets of any Plan or (ii) the purchase or holding of the notes (or any interest therein) by such purchaser or transferee will not constitute a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or a similar violation under any applicable Similar Laws.

Under the terms and conditions contained in an underwriting agreement dated     , 2023, we have agreed to sell to the underwriters named below, for which Citigroup Global Markets Inc., BofA Securities, Inc. and Santander US Capital Markets LLC are acting as representatives, and each underwriter has agreed severally to purchase, the following principal amounts of the notes set forth opposite its name below.

The underwriting agreement provides that the underwriters are obligated to purchase all of the notes if any are purchased.

The underwriters propose to offer the notes initially at the public offering prices on the cover page of this prospectus supplement and may offer the notes to selected broker-dealers at those prices, in the case of the 2024 notes, less a concession of    % of the principal amount per 2024 note, and, in the case of the     notes, less a concession of    % of the principal amount per     note. The underwriters and selected broker-dealers may allow a discount on sales to other broker-dealers, in the case of the 2024 notes, of    % of such principal amount, and, in the case of the     notes, of    % of such principal amount. After the initial public offering of the notes, the public offering prices and concessions and discounts to broker-dealers and other selling terms with respect thereto may be changed. The offering of the notes by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part.

Certain of the underwriters may not be U.S. registered broker-dealers and, therefore, to the extent that they intend to effect any sales of the notes in the United States, they will do so through one or more U.S. registered broker-dealers as permitted by Financial Industry Regulatory Authority regulations.

The 20   notes are a new issue of securities with no established trading market. The existing 2024 notes are not listed on any securities exchange, the notes will not be listed on any securities exchange, and we do not intend to apply for inclusion of the notes on any automated dealer quotation system. We have been advised by the underwriters that they intend to make a market in the notes of each series, but the underwriters are not obligated to do so and may discontinue market making at any time without notice. We can give no assurance as to the liquidity of, or 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. If the notes are traded, they may trade at a discount from their initial offering prices, depending on prevailing interest rates, the markets for similar securities, our operating performance and financial condition, general economic conditions and other factors.

We estimate that our out-of-pocket expenses (not including the underwriting discounts) for this offering will be approximately $     .

The following table shows the amount of the underwriting discounts provided to the underwriters in connection with this offering, expressed as a percentage of the principal amount of the notes and in total:

We expect that delivery of the notes will be made against payment therefor on or about     , 2023, which is the      business day following the date of pricing of the notes (such settlement cycle being referred to as “T+  ”). Under Rule 15c6-1 of the Exchange Act, trades in the secondary market generally are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly,

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

The underwriters may engage in over-allotment, stabilizing transactions, syndicate covering transactions and penalty bids, in accordance with Regulation M under the Exchange Act, as described below:

Such stabilizing transactions, syndicate covering transactions and penalty bids may cause the price of the notes to be higher than it would otherwise be in the absence of such transactions.

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities. Some of the underwriters and their affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with us or our affiliates. They have received, or may in the future receive, customary fees and commissions for these transactions.

In addition, in the ordinary course of their business activities, the underwriters and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. Certain of the underwriters or their affiliates that have a lending relationship with us routinely hedge, and certain other of those underwriters may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, such underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the notes offered hereby. Any 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.

The notes are offered for sale in the United States and in jurisdictions outside the United States, subject to applicable law.

Each of the underwriters has agreed that it will not offer, sell, or deliver any of the notes, directly or indirectly, or distribute this prospectus supplement, the accompanying prospectus or any other offering material relating to the notes, in or from any jurisdiction except under circumstances that will result in compliance with the applicable laws and regulations and which will not impose any obligations on us except as set forth in the underwriting agreement.

Holders may be required to pay stamp taxes and other charges in accordance with the laws and practices of the country in which the notes were purchased. These taxes and charges are in addition to the respective public offering price set forth on the cover page.

The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (“EEA”). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive (EU) 2014/65/ (as amended, “MiFID II”); or (ii) a customer within the meaning of Regulation (EU) 2017/1129, where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Directive 2003/71/EC (as amended, the “Prospectus Regulation”). Consequently no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation. This prospectus supplement and the accompanying prospectus have been prepared on the basis that any offer of notes in any Member State of the EEA will be made pursuant to an exemption under the Prospectus Regulation from the requirement to publish a prospectus for offers of notes. This prospectus supplement and the accompanying prospectus are not a prospectus for the purposes of the Prospectus Regulation.

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