The   % Notes due 20  (the “Notes”) will mature on     , 20 . Prior to maturity, we may redeem any or all of the Notes at any time at the redemption prices described in this prospectus supplement. Interest on the Notes will accrue from    , 2026. We will pay interest on the Notes on      of each year, beginning   , 2027.

The Notes will be issued in minimum denominations of €100,000 and integral multiples of €1,000 in excess thereof.

We intend to apply to list the Notes on the New York Stock Exchange (“NYSE”). The listing application will be subject to approval by the NYSE. We currently expect trading in the Notes on the NYSE to begin less than 30 days after the original issue date. If such listing is obtained, we will have no obligation to maintain such listing, and we may delist the Notes at any time. Currently, there is no established trading market for the Notes.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities, or determined if this prospectus supplement or the accompanying prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

Investing in the Notes involves risks. You should consider carefully the risks set forth in “Risk Factors” beginning on page S-5 of the prospectus supplement and page 2 of the accompanying prospectus, as well as the risks set forth in our other filings with the Securities and Exchange Commission, which are incorporated by reference in this prospectus supplement and the accompanying prospectus, before investing in the Notes.

The underwriters expect to deliver the Notes to purchasers in book-entry form only through a common depositary of Clearstream Banking S.A. (“Clearstream”) and Euroclear Bank SA/NV (“Euroclear” and, together with Clearstream, the “Clearing Systems”), on or about    , 2026.

We have not, and the underwriters have not, authorized anyone to provide you with information different from that contained or incorporated by reference in this prospectus supplement and the accompanying prospectus or any free writing prospectus prepared by or on behalf of us or to which we have referred you. We take no responsibility for, and can provide no assurance as to the reliability of, any other information that others may give you. We are offering to sell the Notes and seeking offers to buy the Notes only in jurisdictions where offers and sales are permitted. The information contained in this prospectus supplement and the accompanying prospectus is accurate only as of the date of this prospectus supplement, regardless of the time of delivery of this prospectus supplement and the accompanying prospectus or any sale of the Notes. You should not assume that the information in this prospectus supplement, the accompanying prospectus, any free writing prospectus or any other material that we authorize, is accurate at any date other than the date included in the respective cover pages of these documents. Our business, financial condition, results of operations and prospects may have changed since those dates.

This document consists of two parts. The first part is the prospectus supplement, which describes the specific terms of this offering. The second part is the accompanying prospectus, which describes more general information, some of which may not apply to this offering. You should read this prospectus supplement, any related free writing prospectus and the accompanying prospectus, and any other offering material that we authorize, together with the documents incorporated by reference as described under “Information We Incorporate by Reference” on page S-9 and the additional information described under the heading “Where You Can Find More Information” on page 3 of the accompanying prospectus.

In this prospectus supplement, except as otherwise indicated or unless the context otherwise requires, “Emerson,” “Company,” “we,” “us” and “our” refer to Emerson Electric Co. and its consolidated subsidiaries. If the information set forth in this prospectus supplement differs in any way from the information set forth in the accompanying prospectus, you should rely on the information set forth in this prospectus supplement.

References in this prospectus supplement to “U.S. dollars,” “U.S. $” or “$” are to the currency of the United States of America and references to “€” and “euro” are to the single currency introduced at the third stage of the European Monetary Union pursuant to the Treaty establishing the European Community, as amended.

IN CONNECTION WITH THIS OFFERING OF THE NOTES, J.P. MORGAN SECURITIES PLC, AS STABILIZING MANAGER (OR ANY PERSONS ACTING ON ITS BEHALF), MAY OVER-ALLOT THE NOTES OR EFFECT TRANSACTIONS WITH A VIEW TO SUPPORTING THE PRICE OF THE NOTES AT A LEVEL HIGHER THAN THAT WHICH MIGHT OTHERWISE PREVAIL. HOWEVER, THIS MAY NOT NECESSARILY OCCUR. TO THE EXTENT REQUIRED BY APPLICABLE LAW, ANY STABILIZATION ACTION MAY ONLY BEGIN ON OR AFTER THE DATE ON WHICH ADEQUATE PUBLIC DISCLOSURE OF THE TERMS OF THE OFFER OF THE NOTES IS MADE AND, IF BEGUN, MAY BE ENDED AT ANY TIME, BUT IT MUST END NO LATER THAN THE EARLIER OF 30 DAYS AFTER THE ISSUE DATE OF THE NOTES AND 60 DAYS AFTER THE DATE OF THE ALLOTMENT OF THE NOTES. ANY STABILIZATION ACTION OR OVER-ALLOTMENT MUST BE CONDUCTED BY THE STABILIZING MANAGER (OR ANY PERSONS ACTING ON ITS BEHALF) IN ACCORDANCE WITH ALL APPLICABLE LAWS AND RULES. ANY LOSS OR PROFIT SUSTAINED AS A CONSEQUENCE OF ANY SUCH OVER-ALLOTMENT OR STABILIZATION SHALL BE FOR THE ACCOUNT OF THE STABILIZING MANAGER.

ANY OF THESE ACTIVITIES MAY HAVE THE EFFECT OF PREVENTING OR RETARDING A DECLINE IN THE MARKET PRICE OF THE NOTES. THEY MAY ALSO CAUSE THE PRICE OF THE NOTES TO BE HIGHER THAN THE PRICE THAT OTHERWISE WOULD EXIST IN THE OPEN MARKET IN THE ABSENCE OF THESE TRANSACTIONS. THE UNDERWRITERS MAY CONDUCT THESE TRANSACTIONS IN THE OVER-THE-COUNTER MARKET OR OTHERWISE. IF THE UNDERWRITERS COMMENCE ANY OF THESE TRANSACTIONS, THEY MAY DISCONTINUE THEM AT ANY TIME.

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

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

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

The Notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (“EEA”). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); or (ii) a customer within the meaning of Directive (EU) 2016/97 (as amended or superseded, the “Insurance Distribution Directive”), 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 Article 2 of Regulation (EU) 2017/1129 (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. Neither this prospectus supplement nor the accompanying prospectus is a prospectus for the purposes of the Prospectus Regulation, and any offer of the Notes in any member state of the EEA is made pursuant to an exemption under the Prospectus Regulation.

Solely for the purposes of each manufacturer’s product approval process, the target market assessment in respect of the Notes has led to the conclusion that: (i) the target market for the Notes is eligible counterparties and professional clients only, each as defined in MiFID II; and (ii) all channels for distribution of the Notes to eligible counterparties and professional clients are appropriate. Any person subsequently offering, selling or recommending the Notes (a “distributor”) should take into consideration the manufacturers’ target market assessment; however, a distributor subject to MiFID II is responsible for undertaking its own target market assessment in respect of the Notes (by either adopting or refining the manufacturers’ target market assessment) and determining appropriate distribution channels.

The Notes are not intended to be offered, sold, distributed or otherwise made available to and should not be offered, sold, distributed or otherwise made available to any retail investor in the United Kingdom (“UK”). For these purposes (a) the expression “retail investor” means a person who is one (or both) of the following: (i) not a “professional client” as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of assimilated law in the UK by virtue of the European Union (Withdrawal) Act 2018 (as amended, and together with any statutory instruments made in exercise of the powers conferred by such Act, the “EUWA”); or (ii) not a “qualified investor” as defined in paragraph 15 of Schedule 1 to the Public Offers and Admissions to Trading Regulations 2024 (the “UK POATRs”); and (b) the expression “offer” includes the communication in any form and by any means of sufficient information on the terms of the offer and the securities to be offered so as to enable an investor to decide to buy or subscribe for such securities. Consequently, no disclosure document required by the UK Financial Conduct Authority (“FCA”) Product Disclosure Sourcebook (the “DISC Sourcebook”) for offering, selling or distributing consumer composite investments or otherwise making them available to retail investors in the UK has been prepared and therefore offering, selling or distributing the Notes or otherwise making them available to any retail investor in the UK may be unlawful under the DISC Sourcebook and The Consumer Composite Investments (Designated Activities) Regulations 2024.

This prospectus supplement and the accompanying prospectus have been prepared on the basis that any offer of Notes in the UK will be made pursuant to an exception from the prohibition on public offers of relevant securities in the UK POATRs in circumstances not requiring a prospectus pursuant to the FCA Handbook Admission to Trading on a Regulated Market Sourcebook (the “PRM Sourcebook”). For the avoidance of doubt, although this document is referred to as a ‘prospectus supplement’ and there are references herein to a ‘prospectus’, neither this prospectus supplement nor the accompanying prospectus is a prospectus for the purposes of the UK POATRs or the PRM Sourcebook.

This prospectus supplement and the accompanying prospectus have not been approved by an authorized person for the purposes of section 21 of the Financial Services and Markets Act 2000 (as amended, the “FSMA”) and accordingly, are only being distributed to, and are only directed at, persons who are outside the UK or persons in the UK who are qualified investors within the meaning of paragraph 15 of Schedule 1 to the UK POATRs who are also (i) investment professionals falling within Article 19(5) of the Financial Services and Markets Act 2000

(Financial Promotion) Order 2005 (the “Financial Promotion Order”), (ii) high net worth entities falling within Article 49(2)(a) to (d) of the Financial Promotion Order, or (iii) other persons to whom they may otherwise lawfully be communicated (each such person being referred to as a “relevant person”). This prospectus supplement, the accompanying prospectus and their contents are confidential and should not be distributed, published or reproduced (in whole or in part) or disclosed by recipients to any other persons in the UK. Any investment or investment activity to which this prospectus supplement and the accompanying prospectus relate is available only to and will be engaged in only with relevant persons. Any person in the UK who is not a relevant person should not act or rely on this prospectus supplement and the accompanying prospectus or any of their contents.

Solely for the purposes of each manufacturer’s product approval process, the target market assessment in respect of the Notes has led to the conclusion that: (i) the target market for the Notes is only eligible counterparties, as defined in the FCA Handbook Conduct of Business Sourcebook (“COBS”), and professional clients, as defined in Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the EUWA (“UK MiFIR”), and (ii) all channels for distribution of the Notes to eligible counterparties and professional clients are appropriate. Any person subsequently offering, selling or recommending the Notes (a “distributor”) should take into consideration the manufacturers’ target market assessment; however, a distributor subject to the FCA Handbook Product Intervention and Product Governance Sourcebook (the “UK MiFIR Product Governance Rules”) is responsible for undertaking its own target market assessment in respect of the Notes (by either adopting or refining the manufacturers’ target market assessment) and determining appropriate distribution channels.

Statements in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference that are not strictly historical may be “forward-looking” statements, which involve risks and uncertainties, and we undertake no obligation to update any such statements to reflect later developments. These risks and uncertainties include the following: the scope, duration and ultimate impacts of the Russia-Ukraine, Middle East and other global conflicts, as well as economic and currency conditions, market demand, pricing, protection of intellectual property, cybersecurity, tariffs, competitive and technological factors, inflation, among others, which are set forth in the “Risk Factors” of Part I, Item 1A, and the “Safe Harbor Statement” of Part II, Item 7, to our Annual Report on Form 10-K for the year ended September 30, 2026, and in subsequent reports filed with the SEC, which are hereby incorporated by reference, as well as in the Risk Factors set forth in this prospectus supplement and the Risk Factors on page 2 of the accompanying prospectus.

An investment in the Notes involves a high degree of risk. In consultation with your own financial and legal advisors, you should carefully consider, among other matters, the factors set forth below as well as the risk factors discussed on page 2 of the accompanying prospectus, and in our Annual Report on Form 10-K for the fiscal year ended September 30, 2026 (which is incorporated by reference into this prospectus supplement and the accompanying prospectus) and in subsequent reports filed with the SEC before deciding whether an investment in the Notes is suitable for you. You should also see “Cautionary Statements Regarding Forward-Looking Statements” in this prospectus supplement and in the accompanying prospectus. Additional risks and uncertainties not currently known to us or those we currently view to be immaterial may also materially and adversely affect our business, financial condition or results of operations. In such a case, you may lose all or part of your investment.

Each potential investor in the Notes must determine the suitability of that investment in light of its own circumstances. In particular, each potential investor should:

The Notes are complex financial instruments and such instruments may be purchased as a way to reduce risk or enhance yield with an understood, measured, appropriate addition of risk to portfolios. A potential investor should not invest in Notes which are complex financial instruments unless it has the expertise (either alone or with the help of a financial advisor) to evaluate how the Notes will perform under changing conditions, the resulting effects on the value of such Notes and the impact this investment will have on the potential investor’s overall investment portfolio.

Generally, all payments of interest and premium, if any, on and the principal of the Notes and any redemption price for the Notes will be made in euro, subject to certain limited exceptions. Neither we nor the underwriters will be obligated to assist the initial investors in obtaining euros or in converting other currencies into euros to facilitate the payment of the purchase price for the Notes.

An investment in the Notes by a purchaser whose home currency is not euro entails significant risks. These risks include the possibility of significant changes in rates of exchange between the holder’s home currency and euro and the possibility of the imposition or subsequent modification of foreign exchange controls with respect to the holder’s home currency or the euro. These risks generally depend on factors over which we have no control, such as economic, financial and political events in the countries issuing such currencies, and the supply of and demand for the relevant currencies.

Foreign currency exchange rates may be affected by, among other factors, existing and expected rates of inflation, existing and expected interest rate levels, the balance of payments between countries, and the extent of governmental surpluses or deficits in various countries. All of these factors are, in turn, sensitive to the monetary, fiscal and trade policies pursued by the governments of various countries important to international trade and finance. In the past, rates of exchange between euro and certain currencies have been highly volatile, and each

holder should be aware that volatility may occur in the future. Moreover, global economic volatility and the actions to be taken by various national governments in response to the volatility could significantly affect the exchange rates between the holder’s home currency and the euro.

Fluctuations in any particular exchange rate that have occurred in the past, however, are not necessarily indicative of fluctuations in the rate that may occur during the term of the Notes. Depreciation of the euro against the holder’s home currency would result in a decrease in the holder’s home currency equivalent yield on the Note, in the holder’s home currency equivalent of the principal payable at the maturity of the Note and generally in the holder’s home currency equivalent market value of the Note.

The EU or one or more of its member states may, in the future, impose exchange controls or modify any exchange controls imposed, which controls could affect exchange rates, as well as the availability of euros at the time of payment of principal of, interest on, or any redemption payment or additional amounts due with respect to, the Notes.

This description of foreign currency risks does not describe all the risks of an investment in securities denominated in a currency other than an investor’s home currency. Investors should consult their own financial and legal advisors as to the risks involved in an investment in the Notes.

If the euro is unavailable to us due to the imposition of exchange controls or other circumstances beyond our control or if the euro is no longer being used by the then member states of the European Monetary Union that have adopted the euro as their currency or for the settlement of transactions by public institutions of or within the international banking community, then in such circumstances, all payments in respect of the Notes will be made in U.S. dollars until the euro is again available to us or so used. In such circumstances, the amount payable on any date in euro will be converted into U.S. dollars on the basis of the then most recently available market exchange rate for euro. Any payment in respect of the Notes so made in U.S. dollars will not constitute an event of default under the Notes or the indenture (as defined in “Description of the Notes”) governing the Notes. This exchange rate may be materially less favorable than the rate in effect at the time the Notes were issued. Such developments, or market perceptions concerning these and related issues, could materially adversely affect the value of the Notes and you may lose a significant amount of your investment in the Notes.

The indenture is, and the Notes will be, governed by the laws of the State of New York. Under New York law, a New York state court rendering a judgment on the Notes would be required to render the judgment in euro. However, the judgment would be converted into U.S. dollars at the exchange rate prevailing on the date of entry of the judgment. Consequently, in a lawsuit for payment on the Notes, investors would bear currency exchange risk until a New York state court judgment is entered, which could be a significant amount of time. A Federal court sitting in New York with diversity jurisdiction over a dispute arising in connection with the Notes would apply the foregoing New York law.

In courts outside of New York, investors may not be able to obtain a judgment in a currency other than U.S. dollars. For example, a judgment for money in an action based on the Notes in many other U.S. federal or state courts ordinarily would be enforced in the United States only in U.S. dollars. The date used to determine the rate of conversion of euro into U.S. dollars would depend upon various factors, including which court renders the judgment and when the judgment is rendered.

The Notes will be represented by interests in the Global Notes, except in certain limited circumstances described therein. The Global Notes will be deposited with a common depositary for the Clearing Systems. Except in certain limited circumstances described in the Global Notes, investors will not be entitled to receive definitive notes. The Clearing Systems will maintain records of the beneficial interests in the Global Notes and, while the Notes are in global form, investors will be able to trade their beneficial interests only through the Clearing Systems.

While the Notes are represented by the Global Notes, we will discharge our payment obligations under the Notes by making payments to or to the order of a nominee for a common depositary for the Clearing Systems for

distribution to their accountholders. A holder of a beneficial interest in the Global Notes must rely on the procedures of the Clearing Systems and, if they do not have an account with the Clearing Systems, on the procedures of the organizations through which such holder owns its beneficial interest in the Notes to receive payments under the Notes. We have no responsibility or liability for the records relating to, or payments made in respect of, beneficial interests in the Global Notes.

Holders of beneficial interests in the Global Notes will not have a direct right to vote in respect of the Notes so represented. Instead, such holders will be permitted to act directly only to the extent that they are enabled in accordance with the applicable procedures of the Clearing Systems to appoint proxies.

The terms of the Notes provide that Notes will be issued with a minimum denomination of €100,000 and multiples of €1,000 in excess thereof. It is possible that the Clearing Systems may process trades which could result in amounts being held in denominations smaller than the minimum denominations. If definitive Notes are required to be issued in relation to such notes in accordance with the provisions of the Global Notes, a holder who does not have the minimum denomination of €100,000 or any integral multiple of €1,000 in excess thereof in its account with the relevant clearing system at the relevant time may not receive all of its entitlement in the form of definitive notes unless and until such time as its holding satisfies the minimum denomination requirement.

The Notes are a new issue of securities. Although we intend to apply for listing of the Notes for trading on the NYSE, no assurance can be given that the Notes will become or will remain listed. Even if the Notes are listed, no assurance can be given that a trading market for such Notes will develop or be maintained, and we have no obligation to maintain such listing, and we may delist the Notes at any time. If no active trading market develops, you may not be able to resell your Notes at their fair market value or at all. Future trading prices of the Notes will depend on many factors, including, among other things, prevailing interest rates, our operating results and the market for similar securities. We have been informed by the underwriters that they currently intend to make a market in these Notes after this offering is completed. However, the underwriters may cease their market-making at any time.

We expect the net proceeds to us from the sale of the Notes to be approximately €   (or approximately $   based upon a euro/U.S. dollar exchange rate as of    , 2026 of €1.00 = $   , as published by the Board of Governors of the Federal Reserve System) before deducting estimated expenses of the offering. We expect to use the net proceeds from the sale of the Notes primarily to repay our commercial paper borrowings, and also for general corporate purposes.

As of November 5, 2026, our commercial paper borrowings had a weighted average interest rate (on a bond-equivalent yield basis) of approximately 4.15% per annum with a weighted average maturity of approximately 90 days.

Certain of the underwriters and/or their affiliates may hold our commercial paper and, accordingly, may receive a portion of the net proceeds of this offering in connection with the repayment of commercial paper.

We will issue the Notes as a separate series of debt securities under an indenture dated as of December 10, 1998 between us and Computershare Trust Company, N.A. (the “Trustee”), as successor to Wells Fargo Bank, National Association as successor to The Bank of New York Mellon Trust Company, N.A., as successor to The Bank of New York Mellon (formerly known as The Bank of New York), and a supplemental indenture to be entered into between us and the Trustee, as trustee for the Notes offered hereby. The indenture, as supplemented by the supplemental indenture, is referred to as the “indenture”. We have summarized selected terms and provisions of the indenture and the Notes below and in the accompanying prospectus under “Description of the Debt Securities.” These summaries are not complete and are subject to, and qualified in their entirety by reference to, the actual provisions of the indenture and the Notes. A copy of the original indenture is an exhibit to the registration statement of which this prospectus supplement and the accompanying prospectus are a part, and we will file the supplemental indenture, which will include the form of Notes, as an exhibit to a Current Report on Form 8-K, and which will be incorporated by reference in the registration statement of which this prospectus supplement and the accompanying prospectus are a part.

We have issued a significant amount of debt securities under the indenture.

Under an agency agreement to be entered into between us, the Trustee, the paying agent, the transfer agent and registrar, we will appoint U.S. Bank Europe DAC, UK Branch to act as paying agent in connection with the Notes, and we will appoint U.S. Bank Trust Company, National Association to act as transfer agent and registrar for the Notes.

The Notes will be initially limited to €   in aggregate principal amount. The Notes will mature on   , 20  . The interest rate on the Notes will be   % per annum.

The Notes will be issued in minimum denominations of €100,000 and integral multiples of €1,000 in excess thereof.

The Notes will be represented by one or more registered global securities that will be deposited with a common depositary and will be registered in the name of the nominee of the common depositary for the accounts of the Clearing Systems. Except as described under “Book-Entry; Delivery and Form - Definitive Notes” in this prospectus supplement, the Notes will not be issuable in definitive form.

Initial holders of the Notes will be required to pay for the Notes in euros, and principal, premium, if any, and interest payments on the Notes, including any payments made upon any redemption of the Notes, will be payable in euros. If, on or after the date of this prospectus supplement, the euro is unavailable to us due to the imposition of exchange controls or other circumstances beyond our control (including the dissolution of the European Monetary Union) or if the euro is no longer used by the then member states of the European Monetary Union that have adopted the euro as their currency or for the settlement of transactions by public institutions within the international banking community, then in such circumstances, all payments in respect of the Notes will be made in U.S. dollars until the euro is again available to us or so used. The amount payable on any date in euro will be converted into U.S. dollars at the rate mandated by the U.S. Federal Reserve Board as of the close of business on the second business day prior to the relevant payment date or, in the event the U.S. Federal Reserve Board has not mandated a rate of conversion, on the basis of the then most recent euro/U.S. dollar exchange rate available on or prior to the second business day prior to the relevant payment date, as determined by us in our sole discretion. Any payment in respect of the Notes so made in U.S. dollars will not constitute an event of default under the Notes or the indenture governing the Notes. Neither the Trustee nor the paying agent shall have any responsibility for any calculation or conversion in connection with the foregoing. Additionally, the Trustee shall not have any liability (i) for the conversion of any currency, (ii) in connection with any exchange rate or other information used in any currency conversion, or (iii) for any exchange risk in connection with any conversion, payment or otherwise, and further, shall only accept or disburse funds in U.S. dollars. See “Risk Factors - The Notes permit us to make payments in U.S. dollars if we are unable to obtain euro.”

Interest on the Notes will accrue from   , 2026. We will pay interest on the Notes annually in arrears on    of each year, beginning in 20  , and on the maturity date for the Notes, to the record holders at the close of business on the preceding    (whether or not such record date is a business day).

For the purposes of the Notes, “business day” means any day that is not a Saturday or Sunday and that is not a day on which banking institutions are authorized or obligated by law or executive order to close in the City of New York or London and on which the real time gross settlement system operated by the Eurosystem (or any successor system) (the T2 system), operates. Interest on the Notes will be computed on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid on the Notes (or   , 20  if no interest has been paid on the Notes), to but excluding the next scheduled interest payment date. This payment convention is referred to as ACTUAL/ACTUAL (ICMA) as defined in the rulebook of the International Capital Market Association.

The rights of holders of beneficial interests of Notes to receive the payments of interest on such Notes are subject to the applicable procedures of the Clearing Systems.

We will not make any sinking fund payments in connection with the Notes.

The Notes are initially being offered in the aggregate principal amount of €  . We may, without the consent of the holders of the Notes, create and issue additional Notes ranking equally with the Notes in all respects, including having the same ISIN and CUSIP numbers, so that such additional Notes shall be consolidated and form a single series with the Notes and shall have the same terms as to status, redemption or otherwise as the Notes; provided that if any such additional Notes are not fungible with Notes initially offered hereby for U.S. federal income tax purposes, such additional Notes will have one or more separate ISIN and CUSIP numbers. No additional Notes may be issued if an Event of Default has occurred and is continuing with respect to such Notes.

The Notes will be our senior unsecured obligations and will rank equally with all of our existing and future unsecured and unsubordinated debt.

The Notes will be redeemable, in whole or from time to time in part, at our option at any time. We may redeem the Notes on any date prior to   . 20   at a redemption price in euro equal to the greater of:

In every such case, the redemption price will also include interest accrued to, but excluding, the date of redemption on the principal balance of the Notes being redeemed.

In addition, at any time on or after   , 20  , we may redeem some or all of the Notes at our option at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus, in every such case, interest accrued to, but excluding, the date of redemption on the principal balance of the Notes being redeemed.

In any case, the principal amount of a note remaining outstanding after a redemption in part shall be €100,000 or an integral multiple of €1,000 in excess thereof.

For purposes of the optional redemption provisions above, the following terms will be applicable:

“Comparable Government Bond” means, in relation to any Comparable Government Bond Rate calculation, at the discretion of an independent investment bank selected by us, a German federal government bond whose maturity is closest to the maturity of the Notes to be redeemed, or if such independent investment bank in its discretion

determines that such similar bond is not in issue, such other German federal government bond as such independent investment bank may, with the advice of three brokers of, and/or market makers in, German federal government bonds selected by us, determine to be appropriate for determining the Comparable Government Bond Rate.

“Comparable Government Bond Rate” means, with respect to any redemption date, the price, expressed as a percentage (rounded to three decimal places, with 0.0005 being rounded upwards), at which the gross redemption yield on the Notes to be redeemed, if they were to be purchased at such price on the third business day prior to the redemption date, would be equal to the gross redemption yield on such business day of the Comparable Government Bond (as defined above) on the basis of the middle market price of the Comparable Government Bond prevailing at 11:00 a.m. (London time) on such business day as determined by an independent investment bank selected by us.

Notice of any redemption will be mailed or otherwise transmitted in accordance with the applicable procedures of the Clearing Systems to the holders of the Notes being redeemed not less than 15 days and not more than 60 days before the redemption date of the Notes being redeemed, as well as in accordance with the indenture. Unless we default on payment of the redemption price, on and after the redemption date, the Notes or any portion of the Notes called for redemption will stop accruing interest. On or before any redemption date, we will deposit with the paying agent or the Trustee money sufficient to pay the accrued interest on the Notes to be redeemed and their redemption price. If less than all of the Notes are to be redeemed, then the Notes shall be selected by the paying agent by a method the paying agent deems to be fair and appropriate or, in the event that the Notes are represented by the Global Notes, beneficial interests therein shall be selected for redemption by the Clearing Systems in accordance with their respective applicable procedures therefor. If the Notes are listed on any national securities exchange, the Clearing Systems will select the Notes for redemption in compliance with their respective procedures and those of the principal national securities exchange on which the Notes are listed. Notwithstanding the foregoing, if less than all of the Notes are to be redeemed, no Notes of a principal amount of €100,000 or less shall be redeemed in part.

The Notes are also subject to redemption if certain events occur involving United States taxation. See “-Redemption for Tax Reasons.”

We will, subject to the exceptions and limitations set forth below, pay such additional amounts as will result in the receipt by each beneficial owner of a note that is not a United States person (as defined below) of such amounts, after withholding or deduction for any present or future tax, assessment or other governmental charge imposed by the United States or a taxing authority in the United States (including any withholding or deduction with respect to the payment of such additional amounts) as would have been received had no such withholding or deduction been required; provided, however, that the foregoing obligation to pay additional amounts shall not apply:

The Notes are subject in all cases to any tax, fiscal or other law or regulation or administrative or judicial interpretation applicable to the Notes. Except as specifically provided under this heading “- Payment of Additional Amounts,” we will not be required to make any payment for any tax, assessment or other governmental charge imposed by any government or a political subdivision or taxing authority of or in any government or political subdivision.

As used under this heading “- Payment of Additional Amounts” and under the heading “- Redemption for Tax Reasons,” the term “United States” means the United States of America (including the states of the United States and the District of Columbia and any political subdivision thereof) and the term “United States person” means any individual who is a citizen or resident of the United States for U.S. federal income tax purposes, a corporation, partnership or other entity created or organized in or under the laws of the United States, any state of the United States or the District of Columbia (other than a partnership that is not treated as a United States person under any applicable U.S. Treasury regulations), or any estate or trust the income of which is subject to United States federal income taxation regardless of its source.

Any reference to amounts payable in respect of the Notes herein or in the indenture shall be deemed to include any additional amounts which may be payable as described above.

If, as a result of any change in, or amendment to, the laws (or any regulations or rulings promulgated under the laws) or treaties of the United States (or any taxing authority in the United States), or any change in, or amendments to, an official position regarding the application or interpretation of such laws, regulations, rulings or treaties, which change or amendment is announced or becomes effective on or after the date of this prospectus supplement, we become or will become obligated to pay additional amounts as described herein under the heading “- Payment of Additional Amounts” with respect to the Notes, then we may at any time at our option redeem, in whole, but not in part, such outstanding Notes on not less than 15 nor more than 60 days’ prior notice, at a redemption price equal to 100% of their principal amount, together with accrued and unpaid interest on those Notes to, but not including, the date fixed for redemption; provided such obligation cannot be avoided by our taking reasonable measures available to us, not including substitution of the obligor under such Notes.

We may defease our obligations with respect to the Notes. For additional information regarding conditions and requirements for defeasance of the Notes, see “Description of the Debt Securities-Defeasance” in the accompanying prospectus.

The Notes will be governed by and construed in accordance with the laws of the State of New York. The supplemental indenture will provide that the Company and the Trustee, and each holder of a Note by its acceptance thereof, irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to the indenture, the supplemental indenture, the Notes or any transaction contemplated thereby.

Computershare Trust Company, N.A. is the Trustee under the Indenture for the Notes. The Trustee is trustee in respect of our other debt securities issued and outstanding under the Indenture, and its affiliate is the registrar and transfer agent for our common stock. The Trustee’s Corporate Trust Office is currently located at 1505 Energy Park Drive, St. Paul, Minnesota 55108, Attention: CCT Administrator for Emerson Electric Co.

Pursuant to an agency agreement to be entered between us, the Trustee, the Paying Agent and the transfer agent and registrar, we will appoint U.S. Bank Europe DAC, UK Branch to act as paying agent in connection with the Notes, and we will appoint U.S. Bank Trust Company, National Association to act as transfer agent and registrar for the Notes. U.S. Bank Europe DAC, UK Branch will also act as the initial authenticating agent on behalf of the Trustee.

At the time of the issuance of the Notes, the paying agent for the Notes, U.S. Bank Europe DAC, UK Branch will maintain its corporate trust paying agent office at 125 Old Broad Street, Fifth Floor, London EC2N 1AR, United Kingdom, Attention: Relationship Management. At the time of the issuance of the Notes, U.S. Bank Trust Company, National Association, in its capacity as transfer agent and registrar, will maintain its office 100 Wall Street, New York, New York 10005.

The Notes will initially be represented by the Global Notes. The Global Notes will be registered in the name of the nominee of the common depositary (the “Common Depositary”) for the accounts of the Clearing Systems.

Upon the registration of the Global Notes in the name of any nominee for the Clearing Systems and delivery of the Global Notes to the Common Depositary, the Clearing Systems will credit each subscriber with a nominal amount of Notes equal to the nominal amount thereof for which it has subscribed and paid.

Except as set forth below, the Global Notes may be transferred, in whole and not in part, only to the Clearing Systems or their respective nominees. You may hold your interests in the Global Notes in Europe through the Clearing Systems, either as a participant in such systems or indirectly through organizations that are participants in such systems. The Clearing Systems will hold interests in the Global Notes on behalf of their respective participating organizations or customers through customers’ securities accounts in Clearstream’s or Euroclear’s names on the books of their respective depositaries. Book-entry interests in the Notes and all transfers relating to the Notes will be reflected in the book-entry records of the Clearing Systems.

The distribution of the Notes will be cleared through the Clearing Systems. Any secondary market trading of book-entry interests in the Notes will take place through the Clearing Systems’ participants and will settle in same-day funds. Owners of book-entry interests in the Notes will receive payments relating to their Notes in euro, except as described in “Description of the Notes-Issuance in Euro.”

The Clearing Systems have established electronic securities and payment transfer, processing, depositary and custodial links among themselves and others, either directly or through custodians and depositaries. These links allow the Notes to be issued, held and transferred among the clearing systems without the physical transfer of certificates. Special procedures to facilitate clearance and settlement have been established among these clearing systems to trade securities across borders in the secondary market.

The policies of the Clearing Systems will govern payments, transfers, exchanges and other matters relating to an investor’s interest in the Notes held by them. Neither, we, the Trustee, the paying agent, the registrar nor the transfer agent have any responsibility for any aspect of the records kept by the Clearing Systems or any of their direct or indirect participants. Additionally, neither we, the Trustee, the paying agent, the registrar or the transfer agent supervise these systems in any way.

The Clearing Systems and their participants perform these clearance and settlement functions under agreements they have made with one another or with their customers. You should be aware that they are not obligated to perform or continue to perform these procedures and may modify them or discontinue them at any time.

Except as provided below, owners of beneficial interests in the Notes will not be entitled to have the Notes registered in their names, will not receive or be entitled to receive physical delivery of the Notes in definitive form and will not be considered the owners or holders of the Notes under the indenture, including for purposes of receiving any reports delivered by us or the trustee pursuant to the indenture. Accordingly, each person owning a beneficial interest in a Note must rely on the procedures of the depositary and, if such person is not a participant, on the procedures of the participant through which such person owns its interest, in order to exercise any rights of a holder of such Note.

We have been advised by the Clearing Systems, respectively, as follows:

Clearstream advises that it is organized under the laws of Luxembourg as a société anonyme, operating as an international central securities depositary. Clearstream holds securities for its participating organizations (“Clearstream Participants”) and facilitates the clearance and settlement of securities transactions between Clearstream Participants through electronic book-entry changes in accounts of Clearstream Participants, thereby eliminating the need for physical movement of certificates. Clearstream provides to Clearstream Participants, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream interfaces with domestic markets in several countries. As a professional depositary, Clearstream is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Sector (Commission de Surveillance du Secteur Financier). Clearstream Participants are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations and may include the underwriters. Indirect access

to Clearstream is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Clearstream Participant, either directly or indirectly.

Distributions with respect to interests in the Notes held beneficially through Clearstream will be credited to cash accounts of Clearstream Participants in accordance with its rules and procedures.

Euroclear advises that it was created in 1968 to hold securities for participants of Euroclear (“Euroclear 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 includes various other services, including securities lending and borrowing and interfaces with domestic markets in several countries. Euroclear is operated by Euroclear Bank SA/NV (the “Euroclear Operator”). All operations are conducted by the Euroclear Operator, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator. Euroclear Participants include banks (including central banks), securities brokers and dealers and other professional financial intermediaries and may include the underwriters. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear Participant, either directly or indirectly.

The Terms and Conditions Governing Use of Euroclear and the related Operating Procedures of the Euroclear System (the “Euroclear Terms and Conditions”), and applicable Belgian law govern securities clearance accounts and cash accounts with the Euroclear Operator. Specifically, these terms and conditions govern:

All securities in Euroclear are held on a fungible basis without attribution of specific certificates to specific securities clearance accounts. The Euroclear Operator acts under the Euroclear Terms and Conditions only on behalf of Euroclear Participants and has no record of or relationship with persons holding securities through Euroclear Participants.

Distributions with respect to interests in the Notes held beneficially through Euroclear will be credited to the cash accounts of Euroclear Participants in accordance with the Euroclear Terms and Conditions.

We understand that investors that hold their Notes through Clearstream or Euroclear accounts will follow the settlement procedures that are applicable to conventional eurobonds in registered form. Notes will be credited to the securities custody accounts of Clearstream and Euroclear participants on the business day following the settlement date, for value on the settlement date. They will be credited either free of payment or against payment for value on the settlement date.

Each of the persons shown in the records of Clearstream and Euroclear or any other clearing system (“Alternative Clearing System”) as the holder of a Note represented by the Global Notes must look solely to Clearstream, Euroclear or any such Alternative Clearing System (as the case may be) for his share of each payment made by us to the holder of the Global Notes and in relation to all other rights arising under the Global Notes, subject to and in accordance with the respective rules and procedures of Clearstream, Euroclear or such Alternative Clearing System (as the case may be). Such persons shall have no claim directly against us in respect of payments due on the Notes for so long as the Notes are represented by the Global Notes and we will discharge such obligations by payment to the holder of the Global Notes in respect of each amount so paid.

We understand that secondary market trading between Clearstream and/or Euroclear participants will occur in the ordinary way following the applicable rules and operating procedures of Clearstream and Euroclear. Secondary market trading will be settled using procedures applicable to conventional eurobonds in registered form.

You should be aware that investors will only be able to make and receive deliveries, payments and other communications involving the Notes through Clearstream and Euroclear on days when those systems are open for business. Those systems may not be open for business on days when banks, brokers and other institutions are open for business in the United States.

In addition, because of time-zone differences, there may be problems with completing transactions involving Clearstream and Euroclear on the same business day as in the United States. United States investors who wish to transfer their interests in the Notes, or to make or receive a payment or delivery of the Notes, on a particular day, may find that the transactions will not be performed until the next business day in Luxembourg or Brussels, depending on whether Clearstream or Euroclear is used.

Clearstream or Euroclear will credit payments to the cash accounts of Clearstream customers or Euroclear participants, as applicable, in accordance with the relevant system’s rules and procedures, to the extent received by its depositary. Clearstream or the Euroclear Operator, as the case may be, will take any other action permitted to be taken by a holder under the indenture on behalf of a Clearstream customer or Euroclear participant only in accordance with its relevant rules and procedures.

Clearstream and Euroclear have agreed to the foregoing procedures in order to facilitate transfers of the Notes among participants of Clearstream and Euroclear. However, they are under no obligation to perform or continue to perform those procedures, and they may discontinue those procedures at any time.

Subject to certain conditions, the Notes represented by the Global Notes are exchangeable for Notes in definitive form of like tenor in minimum denominations of €100,000 principal amount and multiples of €1,000 in excess thereof if:

In all cases, Notes in definitive form delivered in exchange for the Global Notes or beneficial interest therein will be registered in the names, and issued in any approved denominations, requested by or on behalf of the Clearing Systems (in accordance with their customary procedures).

Notices to holders of the Notes will be sent by mail to the registered holders or otherwise transmitted in accordance with the procedures of the Clearing Systems.

The following is a discussion of the material U.S. federal income tax consequences generally applicable in connection with the acquisition, ownership and disposition of the Notes. This discussion is based upon provisions of the Code, applicable U.S. Treasury regulations promulgated thereunder, administrative rulings and judicial decisions in effect as of the date of this prospectus supplement, any of which may subsequently be changed, possibly retroactively, or interpreted differently by the Internal Revenue Service (the “IRS”) so as to result in U.S. federal income tax consequences different from those discussed below. No assurance can be given that the IRS would not assert, or that a court would not sustain, a position contrary to any of those set forth below.

This discussion is for general information purposes only and does not address all aspects of U.S. federal income taxation related to the acquisition, ownership and disposition of the Notes. Except where otherwise noted, this discussion is limited to the tax consequences applicable to beneficial owners who purchase the Notes for cash in this offering at a price equal to the “issue price” for the Notes within the meaning of Section 1273 of the Code (generally, the first price at which a substantial portion of the Notes is sold to the public for cash, not including sales to bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers) and hold the Notes as “capital assets” within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion does not address any state, local or foreign income tax consequences, non-income tax consequences (such as estate or gift tax consequences), or U.S. federal income tax consequences that may be relevant to holders in light of their personal circumstances or to holders subject to special treatment under U.S. federal income tax law, such as:

If a partnership (including any entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds the Notes, the tax treatment of a partner generally will depend upon the status of the partner and the activities of the partnership and certain determinations made at the partner level. A beneficial owner of the Notes that is a partnership and partners in such a partnership should consult their own tax advisors regarding the U.S. federal income tax consequences to them.

If you are considering the purchase of the Notes, you should consult your own tax advisors concerning the U.S. federal income tax consequences to you in light of your particular circumstances, as well as any consequences arising under the non-income tax laws, under the laws of any state, local or non-U.S. taxing jurisdiction, or under any applicable tax treaty.

In this discussion, we use the term “U.S. holder” to refer to a beneficial owner of the Notes that is:

We use the term “non-U.S. holder” to describe a beneficial owner of the Notes that is neither a U.S. holder nor a partnership (including any entity or arrangement that is treated as a partnership for U.S. federal income tax purposes).

YOU SHOULD CONSULT WITH YOUR OWN TAX ADVISOR REGARDING THE U.S. FEDERAL, STATE, LOCAL AND NON-U.S. TAX CONSEQUENCES OF THE ACQUISITION, OWNERSHIP AND DISPOSITION OF THE NOTES IN LIGHT OF YOUR PARTICULAR CIRCUMSTANCES.

In certain circumstances, we may be obligated to pay amounts in excess of the stated interest or principal on the Notes (see “Description of the Notes - Optional Redemption” and “- Payment of Additional Amounts”). We intend to take the position that the possibility of such payments on the Notes does not cause the Notes to be subject to the nonfunctional currency contingent payment debt instrument rules under the applicable U.S. Treasury regulations. Our determination is binding on a holder unless such holder discloses its contrary position in the manner required by applicable U.S. Treasury regulations. Our determination is not, however, binding on the IRS, and if the IRS were to successfully challenge this determination, you might be required to accrue interest income at a higher rate than the stated interest rate on the Notes, and to treat as ordinary income any gain realized on the taxable disposition of a Note. The remainder of this discussion assumes that the Notes will not be treated as nonfunctional currency contingent payment debt instruments. You are urged to consult your own tax advisors regarding the potential application to the Notes of the nonfunctional currency contingent payment debt instrument rules and the consequences thereof.

Payments of interest on the Notes generally will be taxable to a U.S. holder as ordinary interest income at the time such payments are accrued or received, in accordance with the U.S. holder’s method of accounting for U.S. federal income tax purposes. It is anticipated, and this discussion assumes, that the Notes will be issued with no more than a de minimis amount of original issue discount, or “OID,” for U.S. federal income tax purposes.

A U.S. holder that uses the cash method of tax accounting and that receives a payment of interest in euro (including a payment attributable to accrued but unpaid interest upon the sale, exchange, redemption, repurchase or other taxable disposition of a Note) will be required to include in income the U.S. dollar value of the euro-denominated payment received (determined based on the spot rate of exchange on the date the payment is received), regardless of whether the payment is in fact converted to U.S. dollars at that time. A cash basis U.S. holder will not recognize foreign currency exchange gain or loss on the receipt of interest income, but may recognize exchange gain or loss attributable to the actual disposition of the euro received.

A U.S. holder that uses the accrual method of tax accounting will, unless an alternative election is made, accrue interest income in euro and translate that amount into U.S. dollars based on the average spot rate of exchange in effect for the accrual period or, with respect to an accrual period that spans two taxable years, at the average spot rate of exchange for the partial period within the applicable taxable year. Alternatively, an accrual method U.S. holder may elect to translate interest income into U.S. dollars at the spot rate of exchange on the last day of the accrual period (or in the case of a partial accrual period, the spot rate of exchange on the last day of the taxable year) or, if the date of receipt is within five business days of the last day of the interest accrual period, the spot rate of exchange on the date of receipt. A U.S. holder that makes this election must apply it consistently to all debt instruments held by the U.S. holder at the beginning of the first taxable year to which the election applies, and to any debt instruments thereafter acquired, and cannot change the election without the consent of the IRS. A U.S. holder that uses the accrual method will recognize foreign currency exchange gain or loss (which will be treated as ordinary income or loss) with respect to accrued interest income on the date the interest payment (or proceeds from a sale, exchange, redemption, repurchase or other taxable disposition attributable to accrued interest) is actually received. The amount of exchange gain or loss recognized will equal the difference, if any, between the U.S. dollar value of the euro payment received (determined based on the spot rate of exchange on the date the payment is received) in respect of the accrual period and the U.S. dollar value of interest income that has accrued during the accrual period (as determined using the averaging method described in the first sentence of this paragraph, unless an alternative election is made), regardless of whether the payment is in fact converted to U.S. dollars.

A U.S. holder will generally recognize gain or loss on the sale, exchange, redemption, retirement, or other taxable disposition of a Note in an amount equal to the difference between the amount realized upon such disposition (except to the extent the amount realized is attributable to accrued interest not previously included in income, which will be taxable as described above under “-Interest on the Notes”) and the U.S. holder’s adjusted tax basis in such Note. A U.S. holder’s adjusted tax basis in the Note generally will be the U.S. dollar value of the euro used to purchase the Note based on the spot rate of exchange on the purchase date. If the Note is traded on an established securities market, as the Notes are expected to be, a cash basis U.S. holder (and if it elects, an accrual basis U.S. holder) will determine the U.S. dollar value of the euro amount paid for the Note on the settlement date of the purchase.

The amount realized on the sale, exchange, redemption, repurchase or other taxable disposition of a Note for an amount in euro will generally be the U.S. dollar value of such euro based on the spot rate of exchange on the date the Note is disposed of; provided, however, that if the Note is traded on an established securities market, as the Notes are expected to be, a cash basis U.S. holder (and if it elects, an accrual basis U.S. holder) will determine the U.S. dollar value of such euro on the settlement date of the disposition. If an accrual method U.S. holder makes such election, such election must be applied consistently to all debt instruments held by the U.S. holder at the beginning of the first taxable year to which the election applies, and to any debt instruments thereafter acquired, and cannot be changed without the consent of the IRS. If a Note is not traded on an established securities market (or, if a Note is so traded, but a U.S. holder is an accrual basis U.S. holder that has not made the settlement date election), a U.S. holder will recognize currency exchange gain or loss (taxable as ordinary income or loss) to the extent that the U.S. dollar value of the euro received (based on the spot rate of exchange on the settlement date) differs from the U.S. dollar value of the amount realized.

Except as discussed below with respect to currency exchange gain or loss, any gain or loss recognized by a U.S. holder on a taxable disposition of the Note will generally be capital gain or loss, and will be long-term capital gain or loss if the U.S. holder has held the Note for more than one year at the time of the disposition. Otherwise, such capital gain or loss will be a short-term capital gain or loss. Non-corporate U.S. holders may be eligible for reduced rates of U.S. federal income tax on long-term capital gains. The deductibility of capital losses is subject to limitations under the Code.

Gain or loss realized upon the sale, exchange, redemption, repurchase or other taxable disposition of a Note that is attributable to fluctuations in foreign currency exchange rates will be ordinary income or loss. Gain or loss attributable to fluctuations in currency exchange rates generally will equal the difference between (i) the U.S. dollar value of a U.S. holder’s purchase price for the Note in euro, determined using the spot rate of exchange on the date the Note is disposed of, and (ii) the U.S. dollar value of a U.S. holder’s purchase price for the Note in euro, determined using the spot rate of exchange on the date the U.S. holder acquired the Note (or, in each case, determined on the settlement date if the Notes are traded on an established securities market, as the Notes are expected to be, and the U.S. holder is either a cash basis or an electing accrual basis holder). The exchange gain or loss will be recognized only to the extent of the total gain or loss realized by a U.S. holder on the sale, exchange, redemption, repurchase or other taxable disposition of the Note, and generally will be ordinary income or loss.

A U.S. holder’s tax basis in the euros received as interest on or on the sale, exchange, redemption, repurchase or other taxable disposition of a Note will be the U.S. dollar value of such euros based on the spot rate of exchange in effect on the date of receipt of the euros. The amount of gain or loss recognized on a subsequent sale or other disposition of such euros (including its exchange for U.S. dollars) will be equal to the difference between (i) the amount of U.S. dollars, or the fair market value in U.S. dollars of the other property received in such sale or disposition, and (ii) the U.S. holder’s adjusted tax basis in such euros. Any gain or loss recognized by a U.S. holder on a sale, exchange, redemption, repurchase or other taxable disposition of the euros will be ordinary income or loss.

A U.S. taxpayer that participates in a “reportable transaction” will be required to disclose its participation to the IRS. Under the relevant rules, a U.S. holder may be required to treat a foreign currency exchange loss from the Notes as a reportable transaction if this loss meets or exceeds the relevant threshold in the applicable U.S. Treasury regulations, and to disclose its investment by filing Form 8886 with the IRS. Prospective purchasers should consult their tax advisors regarding the application of these rules.

Certain U.S. holders who are individuals, estates or trusts are subject to an additional 3.8% Medicare tax on a portion or all of their net investment income, which generally includes gross income from interest (including interest paid with respect to a Note), dividends, annuities, royalties, rents, net gain attributable to the disposition of property not held in a trade or business (including net gain from the sale, redemption, exchange, retirement or other taxable disposition of a Note) and certain other income, but will be reduced by any deductions properly allocable to such income or net gain. If you are a U.S. holder that is an individual, estate or trust, you are urged to consult your tax advisors regarding the applicability of the Medicare tax to your income and gains in respect of your investment in the Notes.

Information reporting requirements generally will apply to interest on the Notes and the proceeds of a sale of a Note paid to a U.S. holder unless the U.S. holder is an exempt recipient (such as a corporation). Backup withholding at the applicable rate will apply to those payments if the U.S. holder fails to provide its correct taxpayer identification number, or certification of exempt status (generally by providing an IRS Form W-9 or an approved substitute), or if the U.S. holder is notified by the IRS that the US holder has failed to report in full payments of interest and dividend income and is therefore subject to backup withholding. Any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against a U.S. holder’s U.S. federal income tax liability provided the required information is furnished timely to the IRS.

Subject to the discussions below concerning income effectively connected with a U.S. trade or business, backup withholding and FATCA, payments of interest on the Notes made to a non-U.S. holder generally will be exempt from U.S. federal income tax and U.S. federal withholding tax of 30% (or, if applicable, a lower treaty rate), provided:

Such certification requirements will be met if either (1) the non-U.S. holder provides the applicable withholding agent with a properly completed IRS Form W-8BEN or W-8BEN-E (or other applicable form), which includes its name and address and a certification, under penalties of perjury, that the non-U.S. holder is not a “United States person” within the meaning of the Code, or (2) a securities clearing organization, bank or other financial institution that holds customers’ securities in the ordinary course of its trade or business and holds the Notes on behalf of the non-U.S. holder certifies to the applicable withholding agent on IRS Form W-8IMY (or other applicable form) under penalties of perjury that it, or the financial institution between it and the non-U.S. holder, has received from the non-U.S. holder a properly completed IRS Form W-8BEN or W-8BEN-E (or other applicable form), which includes a statement, under penalties of perjury, that such non-U.S. holder is not a “United States person” within the meaning of the Code and provides the applicable withholding agent with a copy of this statement.

If a non-U.S. holder cannot satisfy the requirements described above, payments of interest made to the non-U.S. holder will be subject to the 30% U.S. federal withholding tax, unless the non-U.S. holder provides the applicable withholding agent with a properly executed (1) IRS Form W-8BEN or W-8BEN-E (or other applicable form) claiming an exemption from or reduction in withholding under the benefit of an applicable tax treaty, or

(2) IRS Form W-8ECI (or other applicable form) stating that interest paid on the Notes is not subject to withholding tax because it is effectively connected with the non-U.S. holder’s conduct of a trade or business in the United States.

If interest paid to a non-U.S. holder is effectively connected with the non-U.S. holder’s conduct of a U.S. trade or business (and, if required by an applicable income tax treaty, the non-U.S. holder maintains a U.S. permanent establishment or fixed base to which such interest is attributable), then, although exempt from U.S. federal withholding tax (provided the non-U.S. holder provides appropriate certification), the non-U.S. holder generally will be subject to U.S. federal income tax on such interest in the same manner as if such non-U.S. holder were a U.S. holder. In addition, if the non-U.S. holder is a foreign corporation, such effectively connected interest may be subject to a branch profits tax at a 30% rate (or lower applicable treaty rate). Prospective investors should consult their own tax advisors regarding the tax consequences of the ownership and disposition of the Notes, including the possible imposition of branch profits taxes.

Subject to the discussions below concerning backup withholding and FATCA, and except with respect to accrued but unpaid interest, which will be taxable as described above under “- Interest on the Notes,” a non-U.S. holder generally will not be subject to U.S. federal income tax (and generally no tax will be withheld) on any gain realized on the sale, exchange, redemption, retirement or other taxable disposition of a Note unless (i) such non-U.S. holder is a non-resident alien individual who has been present in the United States for 183 days or more in the taxable year of disposition and certain other conditions are met or (ii) such gain is effectively connected with the conduct of a trade or business in the U.S. by such non-U.S. holder (and, if required by an applicable income tax treaty, such non-U.S. holder maintains a U.S. permanent establishment or fixed base to which such gain is attributable).

If a non-U.S. holder is subject to U.S. federal income tax on the taxable disposition of the Notes because such non-U.S. holder is described in clause (i) of the paragraph above, any gain realized by such non-U.S. holder from the sale, exchange, retirement or other taxable disposition of the Notes generally will be subject to U.S. federal income tax at a 30% rate (or lower applicable treaty rate), which may be offset by certain U.S. source capital losses. If a non-U.S. holder is subject to U.S. federal income tax because such non-U.S. holder is described in clause (ii) of the paragraph above, any gain realized by such non-U.S. holder from the sale, exchange, retirement or other taxable disposition of the Notes will be subject to tax on a net income basis at graduated U.S. federal income tax rates as if the holder were a U.S. person. If such non-U.S. holder is a foreign corporation, it may also be required to pay an additional branch profits tax at a 30% rate (or lower applicable treaty rate).

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 be made available to the tax authorities in the country in which a non-U.S. holder resides pursuant to the provisions of an applicable income tax treaty.

A non-U.S. holder may be subject to backup withholding on payments on the Notes unless the non-U.S. holder complies with certain certification procedures to establish that it is not a United States person or it is otherwise exempt from backup withholding. The certification procedures required to claim an exemption from withholding 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 amount withheld under the backup withholding rules may be credited against the non-U.S. holder’s U.S. federal income tax liability and any excess may be refunded if the proper information is timely furnished to the IRS. Non-U.S. holders should consult their own tax advisors regarding the application of backup withholding to their particular circumstances and the availability of any procedures for obtaining an exemption from backup withholding.

Withholding at a rate of 30% will generally be required under Sections 1471 to 1474 of the Code (commonly referred to as the Foreign Account Tax Compliance Act (“FATCA”)) on interest paid in respect of a Note if such Note is held by or through certain financial institutions (including investment funds), unless such institution

(i) enters into, and complies with, an agreement with the IRS to report, on an annual basis, information with respect to interests in, and accounts maintained by, the institution that are owned by certain U.S. persons and by certain non-U.S. entities that are wholly or partially owned by U.S. persons and to withhold on certain payments or (ii) if required under an intergovernmental agreement between the U.S. and an applicable foreign country, reports such information to its local tax authority, which will exchange such information with the U.S. authorities. An intergovernmental agreement between the United States and an applicable foreign country may modify these requirements. Accordingly, the entity through which a Note is held will affect the determination of whether such withholding is required. Similarly, interest in respect of a Note held by an investor that is a non-financial non-U.S. entity that does not qualify under certain exemptions will be subject to FATCA withholding at a rate of 30%, unless such entity either (i) certifies to us that such entity does not have any “substantial United States owners” or (ii) provides certain information regarding the entity’s “substantial United States owners,” which we will in turn provide to the U.S. Treasury Department. We will not pay any additional amounts to holders of Notes in respect of any amounts withheld under FATCA. Prospective investors should consult their tax advisors regarding the possible implications of the FATCA provisions of the Code on their investment in the Notes. Under proposed U.S. Treasury regulations promulgated by the Treasury Department, which state that taxpayers may rely on the proposed U.S. Treasury regulations until final U.S. Treasury regulations are issued, FATCA withholding will not be imposed on gross proceeds from any sale or disposition of the Notes.

We are selling the Notes to the underwriters named below under a Pricing Agreement dated    , 2026. The underwriters, and the amount of the Notes each of them has severally agreed to purchase from us, are as follows:

Under the terms and conditions of the Pricing Agreement, if the underwriters take any of the Notes, then they are obligated to take and pay for all of the Notes.

The underwriters initially propose to offer part of the Notes directly to the public at the public offering price set forth on the cover page and part to certain dealers at a price that represents a concession not in excess of  % of the principal amount of the Notes.

Any underwriter may allow, and any such dealer may reallow, a concession to certain other dealers not in excess of  % of the principal amount of the Notes.

After the initial offering of the Notes, the underwriters may, from time to time, vary the offering price and other selling terms.

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

The following table shows the underwriting discount that we will pay to the underwriters in connection with this offering of the Notes:

We estimate that we will spend approximately $1,500,000 for printing, ratings agency, trustee and legal fees, and other expenses related to this offering.

The Notes are a new issue of securities, and there is currently no established trading markets for the Notes. We intend to file an application to list the Notes on the NYSE. We expect trading in the Notes on the NYSE to begin less than 30 days after the original issue date, but such listing application is subject to review and approval of the NYSE. Even if the Notes are listed, no assurance can be given that a trading market for the Notes will develop or be maintained, and we have no obligation to maintain such listing, and we may delist the Notes at any time.

The underwriters have advised us that they intend to make a market in the Notes, but they are not obligated to do so. The underwriters may discontinue any market making in the Notes at any time at their sole discretion. Accordingly, we cannot assure you that liquid trading markets will develop for the Notes, that you will be able to sell your Notes at a particular time or that the prices you receive when you sell will be favorable.

In connection with the issue of the Notes, J.P. Morgan Securities plc (in this capacity, the “Stabilizing Manager”) (or any person acting on behalf of the Stabilizing Manager) may over-allot the Notes or effect transactions with a view to supporting the market price of the Notes at a higher level than that which might otherwise prevail. However, there is no assurance that the Stabilizing Manager (or persons acting on behalf of the Stabilizing Manager) will undertake any stabilization action. To the extent required under applicable law, any stabilization action may only begin on or after the date on which adequate public disclosure of the terms of the offer of the Notes is made and, if begun, may be ended at any time, but it must end no later than the earlier of 30 days

after the issue date of the Notes and 60 days after the date of the allotment of the Notes. Any stabilization action or over-allotment must be conducted by the Stabilizing Manager (or any person acting on behalf of the Stabilizing Manager) in accordance with all applicable laws and rules.

In connection with the offering, the underwriters may purchase and sell the Notes in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of Notes than they are required to purchase in the offering.

The underwriters also may impose a penalty bid. This occurs when a particular underwriter repays to the other underwriters a portion of the underwriting discount received by it because J.P. Morgan Securities plc has repurchased Notes sold by or for the account of such underwriter in stabilizing or short covering transactions.

These activities by the underwriters may stabilize, maintain or otherwise affect the market price of the Notes. As a result, the price of the Notes may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued by the underwriters at any time. These transactions may be effected on the NYSE, in the over-the-counter market or otherwise.

Certain of the Underwriters and/or their affiliates may hold our commercial paper and, accordingly, may receive a portion of the net proceeds of this offering in connection with the repayment of commercial paper.

Some of the underwriters and their affiliates have engaged in, and may in the future engage in, commercial banking, financial advisory, investment banking, lending and other commercial dealings in the ordinary course of their business with us or our affiliates, including participating as lenders under our revolving backup credit facility and/or our 364-Day Credit Facility. In particular, JPMorgan Chase Bank, N.A., Bank of America, N.A., Citibank, N.A. and Goldman Sachs Bank USA, affiliates of certain of the underwriters, are acting as lenders and agents under our 364-Day Credit Facility. They have received, and 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 affiliates or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, such underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the Notes offered hereby. Any 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.

It is expected that delivery of the Notes will be made against payment therefor on or about     , 2026, which is the     U.S. business day following the date of the pricing of the Notes. Under Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in one business day unless the parties to that trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes prior to the business day preceding the settlement date will be required, by virtue of the fact that the Notes initially will settle in T+    , to specify an alternative settlement cycle at the time of any such trade to prevent failed settlement and should consult their own advisors.

Other than in the United States, to the best of our knowledge, no action has been taken by us or the underwriters that would permit a public offering of the Notes in any jurisdiction where action for that purpose is required. The Notes may not be offered or sold, directly or indirectly, nor may this prospectus supplement or any other offering material or advertisements in connection with the offer and sale of any such Notes be distributed or published in any jurisdiction, except under circumstances that will result in compliance with the applicable rules and

regulations of that jurisdiction. Persons into whose possession this prospectus supplement comes are advised to inform themselves about and to observe any restrictions relating to the offering of the Notes and the distribution of this prospectus supplement. This prospectus supplement does not constitute an offer to sell or a solicitation of an offer to buy any Notes offered by this prospectus supplement in any jurisdiction in which such an offer or a solicitation is unlawful.

Sales of Notes in the United States by any underwriter that is not a broker-dealer registered with the SEC will be made only through one or more SEC-registered broker-dealers in compliance with applicable securities laws and the rules of the Financial Industry Regulatory Authority, Inc.

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

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

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

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 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 MiFID II; or (ii) a customer within the meaning of the Insurance Distribution Directive, 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 the Prospectus Regulation. Consequently, no key information document required by 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.

The Notes are not intended to be offered, sold, distributed or otherwise made available to and should not be offered, sold, distributed or otherwise made available to any retail investor in the United Kingdom (“UK”). For these purposes (a) the expression “retail investor” means a person who is one (or both) of the following: (i) not a “professional client” as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of assimilated law in the UK by virtue of the EUWA; or (ii) not a “qualified investor” as defined in paragraph 15 of Schedule 1 to the UK POATRs; and (b) the expression “offer” includes the communication in any form and by any means of sufficient information on the terms of the offer and the securities to be offered so as to enable an investor to decide to buy or subscribe for such securities. Consequently, no disclosure document required by the FCA DISC Sourcebook for offering, selling or distributing consumer composite investments or otherwise making them available to retail investors in the UK has been prepared and therefore offering, selling or distributing the Notes or otherwise making them available to any retail investor in the UK may be unlawful under the DISC Sourcebook and The Consumer Composite Investments (Designated Activities) Regulations 2024.

the UK POATRs in circumstances not requiring a prospectus pursuant to the PRM Sourcebook.

Any person in the UK who is not a relevant person should not act or rely on this prospectus supplement and the accompanying prospectus or any of their contents.
