We are offering €    aggregate principal amount of our fixed rate notes due 20  (the “20 fixed rate notes”), and €    aggregate principal amount of our fixed rate notes due 20  (the “20 fixed rate notes”). We refer to the 20 fixed rate notes and the 20 fixed rate notes as the “notes.”

The 20 fixed rate notes will mature on    , 20  and the 20 fixed rate notes will mature on    , 20 .

We may redeem any series of the notes at any time and from time to time at our option, either in whole or in part, at the applicable redemption price described under “Description of the Notes—Optional Redemption.” In addition, we may redeem any series of the notes in whole, but not in part, at any time at our option in the event of certain developments affecting U.S. taxation as described under “Description of the Notes—Redemption for Tax Reasons.”

The notes will be our senior unsecured and unsubordinated obligations and will rank equally among themselves and with all of our existing and future senior unsecured debt and senior to all of our subordinated debt.

We intend to apply to list each series of the notes on the Nasdaq Bond Exchange (“Nasdaq”). We currently expect trading in each series of the notes on Nasdaq to begin within 30 days after the original issue date. If such a listing is obtained, we have no obligation to maintain such listing, and we may delist any series of the notes at any time. Currently there is no public market for any series of 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.

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 , 2024, which is the fourth London business day following the date of this prospectus supplement (the settlement cycle being referred to as “T+4”). Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), trades in the secondary market are generally required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes more than two business days prior to their date of delivery will be required, by virtue of the fact that the notes initially settle in T+4, to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement and should consult their own advisors.

Notice to Prospective Investors in the European Economic Area

PRIIPs Regulation / Prohibition of sales to EEA retail investors. 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, 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 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.

This prospectus supplement and the accompanying prospectus have been prepared on the basis that any offer of the notes in any Member State of the EEA will be made pursuant to an exemption under the Prospectus Regulation, from the requirement to produce a prospectus for offers of notes. Accordingly, any person making or intending to make any offer in a Member State of notes which are the subject of the offering contemplated by this prospectus supplement and the accompanying prospectus may only do so in circumstances in which no obligation arises for us or any of the underwriters to produce a prospectus pursuant to Article 3 of the Prospectus Regulation or supplement a prospectus pursuant to Article 23 of the Prospectus Regulation, in each case, in relation to such offer. Neither we nor the underwriters have authorized, nor do we or they authorize, the making of any offer of notes in circumstances in which an obligation arises for us or the underwriters to publish or supplement a prospectus for such offer.

EU MiFID II product governance / Professional investors and ECPs only target market. 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

S-iii

“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.

Notice to Prospective Investors in the UK

UK PRIIPs Regulation / Prohibition of sales to UK retail investors. 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 UK domestic law by virtue of the European Union (Withdrawal) Act 2018 (the “EUWA”); (ii) a customer within the meaning of the provisions of the Financial Services and Markets Act 2000 (as amended, the “FSMA”) and any rules or regulations made under the FSMA to implement Directive (EU) 2016/97, where that customer would not qualify as a professional client, as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the EUWA; or (iii) not a qualified investor as defined in Article 2 of Regulation (EU) 2017/1129 as it forms part of domestic law by virtue of the EUWA (the “UK Prospectus Regulation”). Consequently no key information document required by Regulation (EU) No 1286/2014 as it forms part of UK domestic law by virtue of the EUWA (the “UK PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the UK has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the UK may be unlawful under the UK PRIIPs Regulation.

UK MiFIR product governance / Professional investors and ECPs only target market. 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 European Union (Withdrawal) Act 2018 (“UK MiFIR”); and (ii) all channels for distribution of the notes to eligible counterparties and professional clients are appropriate.

Use of Proceeds We intend to use the net proceeds of this offering for general corporate purposes, which may include, among other things, the repayment of outstanding debt and the financing of possible acquisitions or business expansion.

Further Issues We may create and issue additional notes of any series ranking equally with the notes of the corresponding series and having the same terms (other than the issue date, the payment of interest accruing prior to the issue date of such further notes or except for the first payment of interest following the issue date of such further notes); provided that such additional notes of any series shall not be issued with the same ISIN or Common Code number as the notes of the corresponding series unless such additional notes are issued in a

S-3

“qualified reopening” of the original series, are otherwise treated as part of the same “issue” of debt instruments as the original series or are issued with less than a de minimis amount of original issue discount, in each case for U.S. federal income tax purposes. Such notes, if issued, will be consolidated and form a single series with the notes of the corresponding series. See “Description of the Notes—Further Issues” in this prospectus supplement.

Concurrent Offering Subject to market conditions and other factors, we may raise additional amounts for general corporate purposes, which may include, among other things, the repayment of outstanding debt and the financing of possible acquisitions or business expansion, in one or more near term U.S. dollar-denominated offerings, which may be substantially concurrent with this offering. There can be no assurance that any such offering will be completed. Settlement of this offering is not conditioned upon settlement of any Concurrent Offering or vice versa.

Any Concurrent Offering would only be made pursuant to a separate prospectus supplement.

Risk Factors For a discussion of factors you should carefully consider before deciding to purchase the notes, see “Risk Factors” beginning on page S-5 of this prospectus supplement and under the headings “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our Annual Report on Form 10-K for the year ended December 31, 2023 and incorporated by reference into this prospectus supplement.

S-4

RISK FACTORS

An investment in the notes may involve various risks. Prior to making a decision about investing in our securities, and in consultation with your own financial and legal advisors, you should carefully consider, among other matters, the following risk factors, as well as those incorporated by reference in this prospectus supplement from our most recent Annual Report on Form 10-K under the headings “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and other filings we may make from time to time with the SEC. In particular, please read carefully the risk factor “A significant percentage of our sales and operations is in non-U.S. jurisdictions and is subject to the economic, political, regulatory, foreign exchange, and other risks of international operations” beginning on page 30 of our Annual Report on Form 10-K for the year ended December 31, 2023.

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

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

If we incur any additional obligations that rank equally with the notes, including trade payables, the holders of those obligations will be entitled to share ratably with the holders of the notes in any proceeds distributed upon our insolvency, liquidation, reorganization, dissolution or other winding up. This may have the effect of reducing the amount of proceeds paid to you. If there are not sufficient assets remaining to pay all these creditors, all or a portion of the notes then outstanding would remain unpaid.

Negative covenants in the Indenture will have a limited effect.

The Indenture governing the notes contains negative covenants that apply to us; however, the limitation on mortgages and limitation on sale and leaseback covenants contain exceptions that will allow us to create, grant or incur liens or security interests with respect to our headquarters and certain other material facilities. See “Description of Debt Securities—Covenants” in the accompanying prospectus. In light of these exceptions, holders of the notes may be structurally or contractually subordinated to new lenders.

Changes in our credit ratings may adversely affect the value of the notes.

We expect that the notes will be rated by one or more nationally recognized statistical rating organizations. Such ratings are not recommendations to buy, sell or hold the notes, are limited in scope, and do not address all material risks relating to an investment in the notes, but rather reflect only the view of each rating agency at the time the rating is issued. An explanation of the significance of such rating may be obtained from such rating agency. There can be no assurance that such credit ratings will remain in effect for any given period of time or that such ratings will not be lowered, suspended or withdrawn entirely by the rating agencies, if, in each rating agency’s judgment, circumstances so warrant. Actual or anticipated changes or downgrades in our credit ratings, including any announcement that our ratings are under further review for a downgrade, could affect the market value of the notes and increase our corporate borrowing costs.

There is no public market for the notes, which could limit their market price or your ability to sell them.

The notes of each series are a new issue of securities for which there is currently no public trading market. Although we intend to apply for listing of the notes of each series for trading on Nasdaq, no assurance can be

S-5

given that the notes of any series will become or will remain listed or that an active trading market for the notes of any series will develop or, if developed, that it will continue. If such a listing is obtained, we have no obligation to maintain such listing, and we may delist the notes of any series at any time. We can give no assurances concerning the liquidity of any market that may develop for the notes of any series offered hereby, the ability of any investor to sell the notes of any series, or the price at which investors would be able to sell them. If a market for the notes of a series does not develop, investors may be unable to resell the notes of such series for an extended period of time, if at all. If a market for the notes of a series does develop, it may not continue or it may not be sufficiently liquid to allow holders to resell any of the notes of such series. Consequently, investors may not be able to liquidate their investment readily, and lenders may not readily accept the notes of such series as collateral for loans.

Future trading prices of each series of the notes will depend on many factors, including prevailing interest rates, our financial condition and results of operations, the then-current ratings assigned to the notes and the market for similar securities. Any trading market that develops would be affected by many factors independent of and in addition to the foregoing, including:

• time remaining to the maturity of the applicable series of the notes;

• outstanding amount of the applicable series of the notes;

• the terms related to optional redemption of the applicable series of the notes; and

• level, direction and volatility of market interest rates generally.

Holders of the notes will receive payments solely in euros subject to limited exceptions.

All payments of interest on and the principal of the notes and any redemption price for the notes will be made in euros, subject to certain limited exceptions. We, the underwriters, the trustee, the transfer agent and registrar and the paying agent with respect to the notes will not be obligated to convert, or to assist any registered owner or beneficial owner of notes in converting, payments of interest, principal, any redemption price or any additional amount in euros made with respect to the notes into U.S. dollars or any other currency.

Holders of the notes may be subject to the effects of foreign currency exchange rate fluctuations, as well as possible exchange controls, relating to the euro.

The initial investors in the notes will be required to pay for the notes in euros. 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 any security denominated in, and all payments with respect to any such security which are to be made in, a currency other than the currency of the country in which an investor in the notes resides or conducts its business or activities (the “investor’s home currency”), entails significant risks not associated with a similar investment in a security denominated in the investor’s home currency. In the case of the notes offered hereby, these risks may include the possibility of significant changes in rates of exchange between the euro and the investor’s home currency and the imposition or modification of foreign exchange controls with respect to the euro or the investor’s home currency.

We have no control over a number of factors affecting the notes offered hereby and foreign exchange rates, including economic, financial and political events that are important in determining the existence, magnitude and longevity of these risks and their effects. Changes in foreign currency exchange rates between two currencies result from the interaction over time of many factors directly or indirectly affecting economic and political conditions in the countries issuing such currencies, and economic and political developments globally and in other relevant countries. 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,

S-6

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.

The exchange rates of an investor’s home currency for euros and the fluctuations in those exchange rates that have occurred in the past are not necessarily indicative of the exchange rates or the fluctuations therein that may occur in the future. Depreciation of the euro against the investor’s home currency would result in a decrease in the investor’s home currency equivalent yield on a note, in the investor’s home currency equivalent of the principal payable at the maturity of that note and generally in the investor’s home currency equivalent market value of that note. Appreciation of the euro in relation to the investor’s home currency would have the opposite effects.

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.

Furthermore, 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 of the notes, the affected investors would be exposed to variations in the U.S. dollar/euro exchange rate until a New York state court judgment is entered, and we cannot predict how long this would take. A U.S. 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 rendered 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.

This description of foreign exchange risks does not describe all the risks of an investment in securities, including, in particular, the notes, that are denominated or payable in a currency other than an investor’s home currency. You should consult your own financial, accounting and legal advisors as to the risks involved in an investment in the notes.

The notes permit us to make payments in U.S. dollars if we are unable to obtain euros and market perceptions concerning the instability of the euro could materially adversely affect the value of 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 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 euros will be converted into U.S. dollars on the basis described under “Description of the Notes—Issuance in Euro; Payment on the Notes.” 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. 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.

In a lawsuit for payment on the notes, an investor may bear currency exchange risk.

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

S-7

euros. 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 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 euros into U.S. dollars would depend upon various factors, including which court renders the judgment and when the judgment is rendered.

Trading in the clearing systems is subject to minimum denomination requirements.

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 that 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 relevant global notes, a holder who does not have the minimum denomination 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.

DESCRIPTION OF THE NOTES

The following description of the particular terms of the notes offered hereby supplements the description of the general terms and provisions of debt securities under the heading “Description of Debt Securities” in the accompanying prospectus. Terms used in this prospectus supplement that are otherwise not defined will have the meanings given to them in the accompanying prospectus. The following summaries of certain provisions of the Indenture do not purport to be complete and are subject to and are qualified in their entirety by reference to all of the provisions of the Indenture. Capitalized and other terms not otherwise defined in this prospectus supplement or in the accompanying prospectus have the meanings given to them in the Indenture. You may obtain a copy of the Indenture from us upon request. See “Where You Can Find More Information” in this prospectus supplement. When used in this section, the terms “we,” “us,” “our” and “Honeywell” refer solely to Honeywell International Inc. and not to its consolidated subsidiaries.

General

We are offering €   aggregate principal amount of our 20 fixed rate notes and €    aggregate principal amount of our 20 fixed rate notes.

Each series of the notes will be issued as a separate series under the Indenture. The 20 fixed rate notes will mature on    , 20  and the 20 fixed rate notes will mature on    , 20  .

The notes will be issued only in registered, book-entry form without interest coupons in minimum denominations of €100,000 and integral multiples of €1,000 in excess thereof.

The notes will not be subject to a sinking fund. The notes will be subject to defeasance as described under “Description of Debt Securities—Defeasance” in the accompanying prospectus.

The Indenture and the notes do not limit the amount of indebtedness that may be incurred or the amount of securities which may be issued by us, and contain no financial or similar restrictions on us, except as described under “Description of Debt Securities—Covenants” in the accompanying prospectus.

If the scheduled maturity date or redemption date for the notes of any series falls on a day that is not a business day, the payment of principal and accrued interest will be made on the next succeeding business day, and no interest on such payment shall accrue for the period from and after the scheduled maturity date or redemption date, as the case may be.

The term “business day” means any day, other than a Saturday or Sunday, (1) which is not a day on which banking institutions in The City of New York or The City of London are authorized or required by law or executive order to close and (2) on which the Trans-European Automated Real-time Gross Settlement Express Transfer system (the TARGET2 system), or any successor thereto, operates.

Issuance in Euro; Payment on the Notes

Initial holders will be required to pay for the notes in euros, and all payments on the notes will be payable in euros; provided that 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 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 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 euros 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 most

S-10

recent U.S. dollar/euro exchange rate published in The Wall Street Journal on or prior to the second business day prior to the relevant payment date. 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. Neither the trustee, transfer agent and registrar nor the paying agent will have any responsibility for any calculation or conversion in connection with the foregoing.

Investors will be subject to foreign exchange risks as to payments on the notes that may have important economic consequences to them. See “Risk Factors” in this prospectus supplement.

Ranking

The notes will be our senior unsecured and unsubordinated debt obligations and will rank equally among themselves and with all of our other existing and future senior unsecured indebtedness and senior to all of our subordinated debt.

Interest

The notes will bear interest from , 2024.

The 20 fixed rate notes will bear interest at a fixed rate of % per annum and the 20 fixed rate notes will bear interest at a fixed rate of % per annum. Interest on the notes will accrue from , 2024 from the most recent date to which interest has been paid or provided for, payable annually in arrears on     of each year (each an “interest payment date”), commencing    , 2025, to holders of record at the close of business on the 15th calendar day (whether or not a business day) immediately preceding the interest payment date or, if the notes are represented by one or more global notes, the close of business on the business day (for this purpose a day on which Clearstream and Euroclear are open for business) immediately preceding the interest payment date; provided, however, that interest payable on the maturity date of the notes or any redemption date of the notes shall be payable to the person to whom the principal of such notes shall be payable.

Interest payable on the notes on any interest payment date, redemption date or maturity date shall be the amount of interest accrued from, and including, the next preceding interest payment date in respect of which interest has been paid or duly provided for (or from and including the original issue date of the notes, if no interest has been paid or duly provided for) to, but excluding, such interest payment date, redemption date or maturity date, as the case may be. This payment convention is referred to as ACTUAL/ACTUAL (ICMA) as defined in the rulebook of the International Capital Markets Association. If any interest payment date falls on a day that is not a business day, the interest payment will be made on the next succeeding day that is a business day, but no additional interest will accrue as a result of the delay in payment. If the maturity date or any redemption date of the notes falls on a day that is not a business day, the related payment of principal, premium, if any, and interest will be made on the next succeeding business day as if it were made on the date such payment was due, and no interest will accrue on the amounts so payable for the period from and after such date to the next succeeding business day. 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 Clearstream and Euroclear.

Optional Redemption

The notes will be redeemable at our option, in whole or in part, at any time prior to    , 20  (the date that is    months prior to the maturity date of the 20  fixed rate notes) with respect to the 20  fixed rate notes (the “20  Par Call Date”) and at any time prior to    , 20  (the date that is    months prior to the maturity date of the 20  fixed rate notes) (the “20  Par Call Date”) with respect to the 20  fixed rate notes, at a redemption price equal to the greater of (i) 100% of the principal amount of the notes to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the notes to be redeemed (exclusive of interest accrued to the date of redemption), discounted to the redemption date on an annual basis (ACTUAL/ACTUAL (ICMA)), at the applicable Comparable Government Bond Rate described

S-11

below plus basis points for the 20  fixed rate notes and plus    basis points for the 20  fixed rate notes, plus, in each case, accrued and unpaid interest on the principal amount of the notes to be redeemed to the date of redemption. We will calculate the redemption price.

At any time on or after the 20  Par Call Date, with respect to the 20  fixed rate notes, and the 20  Par Call Date, with respect to the 20  fixed rate notes, we may redeem the notes, in whole or in part, at a redemption price equal to 100% of the principal amount of such notes of such series being redeemed, plus accrued and unpaid interest on the principal amount of such notes of such series to be redeemed to the date of redemption.

“Comparable Government Bond Rate” means, with respect to any redemption date, the rate per annum equal to the yield to maturity, expressed as a percentage (rounded to three decimal places, with 0.0005 being rounded upwards), on the third business day prior to the date fixed for redemption, calculated in accordance with customary financial practice in pricing new issues of comparable corporate debt securities paying interest on an annual basis (ACTUAL/ACTUAL (ICMA)) of the Comparable Government Bond (as defined below), assuming a price for the Comparable Government Bond (expressed as a percentage of its principal amount) equal to the Comparable Government Bond Price for such redemption date.

“Comparable Government Bond” means, in relation to any Comparable Government Bond Rate calculation, the German government bond (Bundesanleihe) selected by an Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term of the notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of euro-denominated corporate debt securities of a comparable maturity to the remaining term of such notes.

“Independent Investment Banker” means one of the Reference Government Bond Dealers selected by us.

“Comparable Government Bond Price” means, with respect to any redemption date, (1) the arithmetic average of the Reference Government Bond Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference Government Bond Dealer Quotations, or (2) if we obtain fewer than four such Reference Government Bond Dealer Quotations, the arithmetic average of all such quotations.

“Reference Government Bond Dealer” means each of (i) BNP Paribas, Deutsche Bank AG, London Branch, J.P. Morgan Securities plc, Merrill Lynch International, UniCredit Bank GmbH or any of their affiliates that are primary European government securities dealers, and their respective successors; provided that if any of the foregoing or any of their affiliates shall cease to be a primary European government securities dealer (“Primary Dealer”), we shall substitute therefor another Primary Dealer and (ii) three other Primary Dealers selected by us.

“Reference Government Bond Dealer Quotations” means, with respect to each Reference Government Bond Dealer and any redemption date, the arithmetic average, as determined by us, of the bid and asked prices for the Comparable Government Bond (expressed in each case as a percentage of its principal amount) quoted in writing to us by such Reference Government Bond Dealer at 11:00 a.m., Brussels time, on the third business day preceding such redemption date.

Notice of any redemption will be mailed at least 10 days but not more than 60 days before the redemption date to each holder of notes of such series to be redeemed. If we elect to redeem fewer than all the notes of such series, the trustee will select the particular notes of such series to be redeemed by such method that the trustee deems fair and appropriate; provided that if the notes of such series are represented by one or more global securities, beneficial interests therein will be selected for redemption by Clearstream and Euroclear in accordance with their respective applicable procedures therefor; and provided, further, that no notes of a principal amount of €100,000 or less will be redeemed in part.

Any redemption may, at our discretion, be subject to one or more conditions precedent, which will be set forth in the related notice of redemption, including, but not limited to, completion of an offering or financing or

S-12

other transaction or event. In addition, if such redemption is subject to satisfaction of one or more conditions precedent, such notice will describe each such condition, and if applicable, will state that, in our discretion, the redemption date may be delayed until such time (provided, however, that any redemption date will not be more than 60 days after the date of the notice of redemption) as any or all such conditions will be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions will not have been satisfied by the redemption date, or by the redemption date as so delayed. If any such condition precedent has not been satisfied, we will provide written notice to the trustee prior to the close of business one business day prior to the redemption date. Upon receipt of such notice, the notice of redemption will be rescinded or delayed, and the redemption of the notes will be rescinded or delayed as provided in such notice. Upon receipt, the trustee will provide such notice to each holder in the same manner in which the notice of redemption was given.

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

The notes are also subject to redemption prior to maturity if certain changes in U.S. tax law occur. If such changes occur, the notes may be redeemed at a redemption price of 100% of their principal amount plus accrued and unpaid interest to the date of redemption. See “—Redemption for Tax Reasons.”

Payment of Additional Amounts

We will, subject to the exceptions and limitations set forth below, pay as additional interest on the notes such additional amounts as are necessary in order that the net payment by us or a paying agent of the principal, premium and interest with respect to the notes to a holder that is not a United States person (as defined below), 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, will not be less than the amount provided in the notes to be then due and payable; provided, however, that the foregoing obligation to pay additional amounts will not apply:

1. to any tax, assessment or other governmental charge that would not have been imposed but for the holder, a fiduciary, settlor, beneficiary, member or shareholder of the holder, or a person holding a power over an estate or trust administered by a fiduciary holder, being treated as:

a. being or having been present in, or engaged in a trade or business in, the United States, being treated as having been present in, or engaged in a trade or business in, the United States, or having or having had a permanent establishment in the United States;

b. having a current or former connection with the United States (other than a connection arising solely as a result of the ownership of the notes, the receipt of any payment in respect of the notes or the enforcement of any rights under the Indenture), including being or having been a citizen or resident of the United States or treated as being or having been a resident thereof;

c. being or having been a personal holding company, a passive foreign investment company or a controlled foreign corporation for U.S. federal income tax purposes, a foreign tax exempt organization, or a corporation that has accumulated earnings to avoid United States federal income tax;

d. being or having been a “10-percent shareholder,” as defined in section 871(h)(3) of the United States Internal Revenue Code of 1986, as amended (the “Code”), or any successor provision, of us; or

e. being a bank receiving payments on an extension of credit made pursuant to a loan agreement entered into in the ordinary course of its trade or business, within the meaning of section 881(c)(3) of the Code or any successor provision;

S-13

2. to any holder that is not the sole beneficial owner of the notes, or a portion of the notes, or that is a fiduciary, partnership or limited liability company, but only to the extent that a beneficiary or settlor with respect to the fiduciary, a beneficial owner or member of the partnership or limited liability company would not have been entitled to the payment of an additional amount had the beneficiary, settlor, beneficial owner or member received directly its beneficial or distributive share of the payment;

3. to any tax, assessment or other governmental charge that would not have been imposed but for the failure of the holder or any other person to comply with certification, identification or information reporting requirements concerning the nationality, residence, identity or connection with the United States of the holder or beneficial owner of the notes, if compliance is required by statute, by regulation of the United States or any taxing authority therein or by an applicable income tax treaty to which the United States is a party as a precondition to exemption from such tax, assessment or other governmental charge;

4. to any tax, assessment or other governmental charge that is imposed otherwise than by withholding by us or a paying agent from the payment;

5. to any estate, inheritance, gift, sales, excise, transfer, wealth, capital gains or personal property tax or similar tax, assessment or other governmental charge;

6. to any tax, assessment or other governmental charge that would not have been imposed but for the presentation by the holder of any note, where presentation is required, for payment on a date more than 30 days after the date on which payment became due and payable or the date on which payment thereof is duly provided for, whichever occurs later;

7. to any tax, assessment or other governmental charge required to be withheld or deducted that is imposed on a payment pursuant to Sections 1471 through 1474 of the Code (or any amended or successor version of such Sections that is substantively comparable and not materially more onerous to comply with), any Treasury regulations promulgated thereunder, or any other official interpretations thereof (collectively, “FATCA”), any agreement (including any intergovernmental agreement) entered into in connection therewith, or any law, regulation or other official guidance enacted in any jurisdiction implementing FATCA or an intergovernmental agreement in respect of FATCA;

8. any tax, assessment or other governmental charge that is imposed or withheld solely by reason of a change in law, regulation, or administrative or judicial interpretation that becomes effective more than 15 days after the payment becomes due or is duly provided for, whichever occurs later;

9. any tax, assessment or other governmental charge imposed by reason of the failure of the beneficial owner to fulfill the statement requirements of Section 871(h) or Section 881(c) of the Code;

10. any tax imposed pursuant to Section 871(h)(6) or 881(c)(6) of the Code (or any amended or successor provisions); or

11. in the case of any combination of items (1) through (10).

Except as specifically provided under this heading “—Payment of Additional Amounts,” we will not be required to pay additional amounts in respect of any tax, assessment or other governmental charge. References in this prospectus supplement and the accompanying prospectus to any payment on the notes include the related payment of additional amounts, as applicable.

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, any state thereof, and the District of Columbia, and the term “United States person” means (i) any individual who is a citizen or resident of the United States for U.S. federal income tax purposes, (ii) a corporation, partnership or other entity created or organized in or under the laws of the United States, any state thereof or the District of Columbia (other than a partnership that is not treated as a United States person for U.S. federal income tax purposes), (iii) any estate the income of which

S-14

is subject to U.S. federal income taxation regardless of its source, or (iv) any trust if a U.S. court can exercise primary supervision over the administration of the trust and one or more United States persons can control all substantial trust decisions, or if a valid election is in place to treat the trust as a United States person.

Redemption for Tax Reasons

If, as a result of any change in, or amendment to, the laws of the United States or the official interpretation thereof that is announced or becomes effective on or after the date of this prospectus supplement, we become or, based upon a written opinion of independent counsel selected by us, will become obligated to pay additional amounts as described herein under the heading “—Payment of Additional Amounts” with respect to the notes of any series, then we may at any time at our option redeem, in whole, but not in part, the notes of such series on not less than 10 nor more than 60 days’ prior notice, at a redemption price equal to 100% of their principal amount, plus accrued and unpaid interest on the notes of such series to be redeemed to the date of redemption.

Further Issues

We may from time to time, without notice to or the consent of the registered holders of a series of notes, create and issue further debt securities of any such series ranking equally with the notes of the corresponding series and having the same terms in all respects (other than the issue date, the payment of interest accruing prior to the issue date of such further notes or except for the first payment of interest following the issue date of such further notes); provided that such additional debt securities of any series shall not be issued with the same ISIN or Common Code number as the notes of its corresponding series unless such additional debt securities are issued in a “qualified reopening” of the original series, are otherwise treated as part of the same “issue” of debt instruments as the original series or are issued with less than a de minimis amount of original issue discount, in each case for U.S. federal income tax purposes. Such further debt securities will be consolidated and form a single series with the notes of the corresponding series.

Book-Entry System

Global Clearance and Settlement

The notes will be issued in the form of one or more global notes (each a “global note”) in fully registered form, without coupons, and will be deposited on the closing date with, or on behalf of, a common depositary for, and in respect of interests held through, Clearstream and Euroclear. Except as described herein, certificates will not be issued in exchange for beneficial interests in the global notes.

Except as set forth below, the global notes may be transferred, in whole and not in part, only to a common depositary for Clearstream or Euroclear or its nominee.

Beneficial interests in the global notes will be represented, and transfers of such beneficial interests will be effected, through accounts of financial institutions acting on behalf of beneficial owners as direct or indirect participants in Clearstream or Euroclear. Those beneficial interests will be in denominations of €100,000 and integral multiples of €1,000 in excess thereof. Investors may hold notes directly through Clearstream or Euroclear, if they are participants in such systems, or indirectly through organizations that are participants in such systems.

Owners of beneficial interests in the global notes will not be entitled to have notes registered in their names, and will not receive or be entitled to receive physical delivery of notes in definitive form. Except as provided below, beneficial owners 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 beneficial owner must rely on the procedures of the clearing systems and, if such person is not a participant of the clearing systems, on the procedures of the participant through which such person owns its interest, to exercise

S-15

any rights of a holder under the Indenture. Under existing industry practices, if we request any action of holders or a beneficial owner desires to give or take any action which a holder is entitled to give or take under the Indenture, the clearing systems would authorize their participants holding the relevant beneficial interests to give or take action and the participants would authorize beneficial owners owning through the participants to give or take such action or would otherwise act upon the instructions of beneficial owners. Conveyance of notices and other communications by the clearing systems to their participants, by the participants to indirect participants and by the participants and indirect participants to beneficial owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time. The laws of some jurisdictions require that certain purchasers of securities take physical delivery of such securities in certificated form. These limits and laws may impair the ability to transfer beneficial interests in global notes.

Persons who are not Clearstream or Euroclear participants may beneficially own notes held by the common depositary for Clearstream and Euroclear only through direct or indirect participants in Clearstream and Euroclear. So long as the common depositary for Clearstream and Euroclear is the registered owner of the global note, the common depositary for all purposes will be considered the sole holder of the notes represented by the global note under the Indenture and the global notes.

If the applicable depositary is at any time unwilling or unable to continue as depositary for any of the global notes and a successor depositary is not appointed by us within 90 days, or if we have been notified that both Clearstream and Euroclear have been closed for business for a continuous period of 14 days (other than by reason of holiday, statutory or otherwise) or have announced an intention permanently to cease business or have in fact done so and no successor clearing system is available, we will issue the notes in definitive form in exchange for the applicable global notes. We will also issue the notes in definitive form in exchange for the global notes if an event of default has occurred with regard to the notes represented by the global notes and has not been cured or waived. In addition, we may at any time and in our sole discretion determine not to have the notes represented by the global notes and, in that event, will issue the notes in definitive form in exchange for the global notes. In any such instance, an owner of a beneficial interest in the global notes will be entitled to physical delivery in definitive form of the notes represented by the global notes equal in principal amount to such beneficial interest and to have such notes registered in its name. The notes so issued in definitive form will be issued as registered in minimum denominations of €100,000 and integral multiples of €1,000 thereafter, unless otherwise specified by us. The notes in definitive form can be transferred by presentation for registration to the registrar at our office or agency for such purpose and must be duly endorsed by the holder or his or her attorney duly authorized in writing, or accompanied by a written instrument or instruments of transfer in form satisfactory to us or the registrar duly executed by the holder or his attorney duly authorized in writing. We may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any exchange or registration of transfer of definitive notes.

Clearing Systems

We have been advised by Clearstream and Euroclear, respectively, as follows:

Clearstream. Clearstream advises that it is incorporated under the laws of Luxembourg as a professional 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 its participants, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. As a professional depositary, Clearstream is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Sector (Comission de Surveillance du Secteur Financier). Clearstream Participants are recognized financial institutions around the world, including underwriters, securities brokers and dealers,

S-16

banks, trust companies, clearing corporations and certain other organizations. 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 the notes held beneficially through Clearstream will be credited to cash accounts of Clearstream Participants in accordance with its rules and procedures in accordance with its rules and procedures.

Euroclear. 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, or 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:

• transfers of securities and cash within Euroclear;

• withdrawal 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. 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.

Clearstream and Euroclear Arrangements

So long as Clearstream or Euroclear or their nominee or their common depositary is the registered holder of the global notes, Euroclear, Clearstream or such nominee or common depositary, as the case may be, will be considered the sole owner or holder of the notes represented by such notes for all purposes under the Indenture and the notes. Payments of principal, interest and additional amounts, if any, in respect of the global notes will be made to Euroclear, Clearstream or such nominee or common depositary, as the case may be, as registered holder thereof. None of us, the trustee, the transfer agent, the paying agent and registrar, any underwriter and any affiliate of any of the above or any person by whom any of the above is controlled (as such term is defined in the Securities Act of 1933, as amended) will have any responsibility or liability for any records relating to or payments made on account of beneficial ownership interests in the global notes or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

Distributions of principal and interest with respect to the global notes will be credited in euros to the extent received by Clearstream or Euroclear from the trustee or the paying agent, as applicable, to the cash accounts of Clearstream or Euroclear customers in accordance with the relevant system’s rules and procedures.

S-17

Because Clearstream and Euroclear can only act on behalf of participants, who in turn act on behalf of indirect participants, the ability of a person having an interest in the global notes to pledge such interest to persons or entities which do not participate in the relevant clearing system, or otherwise take actions in respect of such interest, may be affected by the lack of a physical certificate in respect of such interest.

The holdings of book-entry interests in the global notes through Clearstream and Euroclear will be reflected in the book-entry accounts of each such institution. As necessary, the registrar will adjust the amounts of the global notes on the register for the accounts of the common depositary to reflect the amounts of notes held through Clearstream and Euroclear, respectively.

Initial Settlement

Investors holding their notes through Clearstream or Euroclear accounts will follow the settlement procedures applicable to conventional eurobonds in registered form. Notes will be credited to the securities custody accounts of Clearstream and Euroclear holders on the settlement date against payment for value on the settlement date.

Secondary Market Trading

Because the purchaser determines the place of delivery, it is important to establish at the time of trading of any notes where both the purchaser’s and seller’s accounts are located to ensure that settlement can be made on the desired value date.

Secondary market sales of book-entry interests in the notes held through Clearstream or Euroclear to purchasers of book-entry interests in the global notes through Clearstream or Euroclear will be conducted in accordance with the normal rules and operating procedures of Clearstream and Euroclear and will be settled using the procedures applicable to conventional eurobonds in same-day funds.

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. U.S. 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 and Euroclear will credit payments to the cash accounts of Euroclear participants or Clearstream customers 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 Euroclear Participant or Clearstream customer 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.

The information in this section concerning Clearstream and Euroclear and their book-entry systems has been obtained from sources that we believe to be reliable, but we take no responsibility for the accuracy of that information. In addition, the description of the clearing systems in this section reflects our understanding of the rules and procedures of Clearstream and Euroclear as they are currently in effect. Those clearing systems could change their rules and procedures at any time.

S-18

None of Honeywell, the underwriters or the trustee, transfer agent, paying agent or registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of the beneficial interests in a global note, or for maintaining, supervising or reviewing any records relating to such beneficial interests.

Notices

Notices to holders of the notes will be sent by mail or email to the registered holders, or otherwise in accordance with the procedures of the applicable depositary.

Regarding the Trustee, Paying Agent, Transfer Agent and Registrar

Deutsche Bank Trust Company Americas will be the trustee, paying agent, transfer agent and registrar with respect to the notes. We and our affiliates maintain various commercial and service relationships with the trustee and its affiliates in the ordinary course of business. Deutsche Bank Trust Company Americas has relationships with us as described under the heading “Description of Debt Securities—Regarding the Trustee” in the accompanying prospectus. An affiliate of the trustee is one of the underwriters in this offering and may be an underwriter in any Concurrent Offering and a participant in our $1.5 billion 364-Day Credit Agreement, maturing in March 2024 (unless converted to a term loan) and our $4.0 billion Amended and Restated Five Year Credit Agreement, maturing in March 2028.

Listing

We intend to apply to list each series of the notes on Nasdaq. We currently expect trading in each series of the notes on Nasdaq to begin within 30 days after the original issue date. If such a listing is obtained, we have no obligation to maintain such listing and we may delist any series of the notes at any time. Currently, there is no public market for any series of the notes.

Governing Law

The Indenture and the notes for all purposes shall be governed by and construed in accordance with the laws of the State of New York.

S-19

UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following discussion summarizes material U.S. federal income tax considerations that may be relevant to you if you invest in the notes. This discussion is based on the Internal Revenue Code of 1986, as amended (the “Code”), and Treasury Regulations, rulings and judicial decisions now in effect, all of which may change. Any change could apply retroactively and could affect the continued validity of this summary. You will be a U.S. holder if you are a beneficial owner of notes that is a (i) an individual who is a citizen or resident of the United States for U.S. federal income tax purposes, (ii) a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia, (iii) or any other person that is subject to U.S. federal income tax on a net income basis in respect of an investment in the notes. You will be a non-U.S. holder if you are a beneficial owner of notes that is an individual, corporation, estate or trust and is not a U.S. holder. This discussion applies only to beneficial owners of notes that will hold notes as capital assets and acquired notes upon original issuance at the “issue price,” which for a series of notes will equal the first price at which a substantial amount of the notes of that series is sold for money to the public (not including bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers). This discussion does not address considerations that may be relevant to you if you are an investor that is subject to special tax rules, such as a bank, real estate investment trust, regulated investment company, insurance company, dealer in securities, trader in securities or commodities that elects mark-to-market treatment, person that will hold notes as a position in a “straddle,” conversion or as part of a “synthetic security” or other integrated transaction or who has entered into a “constructive sale” with respect to a note, tax-exempt organization, a person who is liable for the alternative minimum tax, a U.S. person whose “functional currency” is not the U.S. dollar, a U.S. expatriate, a nonresident alien individual present in the United States for more than 182 days in a taxable year, or entities taxed as partnerships or the partners therein.

This discussion does not describe the application of the Medicare net investment income tax or special timing rules prescribed under section 451(b) of the Code, any tax consequences arising out of the tax laws of any state, local or foreign jurisdiction, or any possible applicability of U.S. federal gift or estate tax.

This discussion does not address non-U.S. holders that hold their notes in connection with a U.S. trade or business. Such non-U.S. holders should consult their tax advisers regarding the consequences of purchasing, owning and disposing of the notes.

You should consult your tax advisor about the tax consequences of purchasing, holding or disposing of notes, including the relevance to your particular situation of the considerations discussed below, as well as the relevance to your particular situation of state, local, foreign or other tax laws.

U.S. Holders

Payments of Interest

Payments of interest on a note will be taxable to you as ordinary income at the time that you actually or constructively receive or accrue such amounts (in accordance with your regular method of tax accounting). It is expected, and this discussion assumes, that the notes will be issued with less than a de minimis amount of original issue discount (“OID”). In general, however, if the notes are issued with more than de minimis OID, a U.S. holder will be required to include OID in gross income, as ordinary income, under a “constant-yield method” before the receipt of cash attributable to such income, regardless of the U.S. holder’s regular method of accounting for U.S. federal income tax purposes. OID will be accrued in euro currency and translated into dollars by U.S. holders in the same manner as interest income accrued by an accrual basis U.S. Holder, as described in the next paragraph. The U.S. holder generally will recognize foreign currency gain or loss to the extent the amount accrued differs from the U.S. dollar value of the euro currency amounts when received.

The amount of interest income realized by a U.S. holder that uses the cash method of tax accounting will be the U.S. dollar value of the euro payment based on the exchange rate in effect on the date of receipt regardless of

S-20

whether the payment in fact is converted into U.S. dollars. A U.S. holder that uses the accrual method of accounting for tax purposes will accrue interest income on the note in euros and translate the amount accrued into U.S. dollars based on the average exchange rate in effect during the interest accrual period (or portion thereof within the U.S. holder’s taxable year), or, at the accrual basis U.S holder’s election, at the spot rate of exchange on the last day of the accrual period (or the last day of the taxable year within such accrual period if the accrual period spans more than one taxable year), or on the date of receipt if such date is within five business days of the last day of the accrual period. A U.S. holder that makes such election must apply it consistently to all debt instruments from year to year and cannot change the election without the consent of the Internal Revenue Service (the “IRS”). A U.S. holder that uses the accrual method of accounting for tax purposes will recognize foreign currency gain or loss, as the case may be, on the receipt of an interest payment made with respect to a note if the exchange rate in effect on the date the payment is received differs from the rate applicable to a previous accrual of that interest income. This foreign currency gain or loss will be treated as ordinary income or loss but generally will not be treated as an adjustment to interest income received on the note.

Purchase, Sale, Exchange, Redemption and Retirement of Notes

Your tax basis in a note generally will equal the cost of the note to you. The cost of the note to a U.S. holder will be the U.S. dollar value of the foreign currency purchase price on the date of purchase. In the case of a note that is traded on an established securities market, a cash basis U.S. holder (and, if it so elects, an accrual basis U.S. holder) will determine the U.S. dollar value of the cost of the note by translating the amount paid at the spot rate of exchange on the settlement date of the purchase. The conversion of U.S. dollars to euros and the immediate use of those euros to purchase a note generally will not result in taxable gain or loss for a U.S. holder. You may recognize foreign currency gain or loss (treated as ordinary income or loss) if you purchase a note with previously owned euros.

When you sell or exchange a note, or if a note that you hold is retired or redeemed, you generally will recognize gain or loss equal to the difference between the amount you realize on the transaction (excluding any accrued interest, which will be subject to tax in the manner described above under “—Payments of Interest”) and your tax basis in the note. The amount realized upon the sale, exchange, redemption or retirement of a note will be the U.S. dollar value of the euros received calculated at the exchange rate in effect on the date the note is sold, exchanged, redeemed or retired, and your tax basis in any such euros received will equal the U.S. dollar value of the euros, determined at the time of sale, exchange, redemption or retirement. In the case of a note that is traded on an established securities market, a cash basis U.S. holder, and if it so elects, an accrual basis U.S. holder, will determine the U.S. dollar value of the amount realized by translating the amount realized at the spot rate on the settlement date of the sale, exchange, redemption or retirement. If you are an accrual basis U.S. holder and either (i) you do not make such an election or (ii) the note is not treated as traded on an established securities market, you will recognize exchange gain or loss to the extent of currency exchange fluctuations during the period between the date of the disposition and the settlement date of the sale. The election available to accrual basis U.S. holders in respect of the purchase and sale of notes traded on an established securities market, discussed above, must be applied consistently to all debt instruments from year to year and cannot be changed without the consent of the IRS.

Except as described below with respect to foreign currency gain or loss, the gain or loss that you recognize on the sale, exchange, redemption or retirement of a note generally will be capital gain or loss, and will be long-term capital gain or loss if you have held the note for more than one year on the date of disposition. Net long-term capital gain recognized by a non-corporate U.S. holder generally is subject to tax at a lower rate than net short-term capital gain or ordinary income. The ability of U.S. holders to offset capital losses against ordinary income is limited. If exchange rates fluctuate, U.S. holders may recognize foreign currency gain or loss, if any, measured by the difference between (i) the U.S. dollar value of your purchase price in euros of the note, determined using the spot rate on the settlement date or trade date, as described above, of the sale, exchange, redemption or retirement of the note, and (ii) the U.S. dollar value of your purchase price in euros of the note, determined using the spot rate on the date you acquired the note. This foreign currency gain or loss recognized by

S-21

a U.S. holder on the sale, exchange, redemption or retirement of a note generally will be treated as ordinary income or loss. In addition, upon the sale, exchange, redemption or retirement of a note, a U.S. holder that uses the accrual method may realize foreign currency gain or loss attributable to amounts received in respect of accrued and unpaid interest. This foreign currency gain or loss will not be treated as an adjustment to interest income received on the notes. The amount of foreign currency gain or loss realized with respect to principal and amounts attributable to accrued interest will, however, be limited to the amount of overall gain or loss realized on the disposition.

Non-U.S. Holders

Payments of Interest

Subject to the discussions below under “Information Reporting and Backup Withholding” and “FATCA,” payments of interest on the notes to a non-U.S. holder generally will be exempt from withholding of U.S. federal income tax under the portfolio interest exemption provided that (i) the non-U.S. holder properly certifies as to its foreign status by providing a properly executed IRS Form W-8BEN or W-8BEN-E (or appropriate substitute form) to the applicable withholding agent, (ii) the non-U.S. holder does not actually or constructively own 10% or more of the total combined voting power of our stock entitled to vote; and (iii) the non-U.S. holder is not a controlled foreign corporation that is related to us actually or constructively through stock ownership.

Sale, Exchange, Retirement or Other Disposition

Subject to the discussions under “Information Reporting and Backup Withholding” below, a non-U.S. holder generally will not be subject to U.S. federal income tax on any gain realized on the sale, exchange, retirement or other disposition of a note.

Information Reporting and Backup Withholding

Information returns will be filed with the IRS in connection with payments on the notes made to, and the proceeds of dispositions of notes effected by, certain U.S. holders. In addition, certain U.S. holders may be subject to backup withholding in respect of such amounts if they do not provide their taxpayer identification numbers to the person from whom they receive payments. Non-U.S. holders generally will be required to comply with applicable certification procedures to establish that they are not U.S. holders in order to avoid the application of such information reporting requirements and backup withholding. The amount of any backup withholding from a payment to a U.S. or non-U.S. holder will be allowed as a credit against the holder’s U.S. federal income tax liability and may entitle the holder to a refund, provided that the required information is timely furnished to the IRS.

Reportable Transactions

A U.S. holder that participates in a “reportable transaction” will be required to disclose its participation to the IRS. Under the relevant rules, since the notes are denominated in a foreign currency, a U.S. holder may be required to treat a foreign currency exchange loss from the notes as a reportable transaction if this loss exceeds the relevant threshold in the regulations ($50,000 in a single taxable year, if the U.S. holder is an individual or trust, or higher amounts for other U.S. holders), and to disclose its investment by filing a Form 8886 with the IRS. A penalty in an amount not exceeding $10,000 in the case of a natural person and $50,000 in all other cases is generally imposed on any taxpayer that fails to timely file an information return with the IRS with respect to a transaction resulting in a loss that is treated as a reportable transaction. Prospective purchasers are urged to consult their tax advisors regarding the application of these rules.

FATCA

Under the U.S. tax rules known as the Foreign Account Tax Compliance Act (“FATCA”), a holder of notes will generally be subject to a 30% U.S. withholding tax on interest payments on the notes if the holder is not

S-22

FATCA compliant, or holds its notes through a foreign financial institution that is not FATCA compliant. In order to be treated as FATCA compliant, a holder or foreign financial institution must provide certain documentation (usually an IRS Form W-8BEN or W-8BEN-E) containing information about its identity, its FATCA status, and if required, its direct and indirect U.S. owners. These requirements may be modified by the adoption or implementation of an intergovernmental agreement between the U.S. and another country or by future U.S. Treasury Regulations. If any taxes are required to be deducted or withheld from any payments in respect of the notes as a result of a beneficial owner or intermediary’s failure to comply with the foregoing rules, no additional amounts will be paid on the notes as a result of the deduction or withholding of such tax.

Documentation that holders provide in order to be treated as FATCA compliant may be reported to the IRS and other tax authorities, including information about a holder’s identity, its FATCA status, and if applicable, its direct and indirect U.S. owners. Prospective investors should consult their own tax advisers about how information reporting and the possible imposition of withholding tax under FATCA may apply to their investment in the notes.

S-23

CERTAIN EUROPEAN UNION TAX CONSIDERATIONS

The Proposed Financial Transaction Tax

The European Commission has published a proposal (the “Commission’s Proposal”) for a Directive for a common financial transaction tax (“FTT”) in Austria, Belgium, Estonia, France, Germany, Greece, Italy, Portugal, Slovakia, Slovenia and Spain (the “participating Member States”). However, Estonia has since stated that it will not participate.

The Commission’s Proposal has very broad scope and could, if introduced in its current form, apply to certain dealings in the notes in certain circumstances.

Under the Commission’s Proposal, the FTT could apply in certain circumstances to persons both within and outside of the participating Member States. Generally, it would apply to certain dealings in the notes where at least one party is a financial institution, and at least one party is established in a participating Member State. A financial institution may be, or be deemed to be, “established” in a participating Member State in a broad range of circumstances, including (a) by transacting with a person established in a participating Member State or (b) where the financial instrument which is subject to the dealings is issued in a participating Member State.

The FTT remains subject to negotiation between the participating Member States and the legality of the proposal is uncertain. It may therefore be altered prior to any implementation, the timing of which is unclear. Additional EU Member States may decide to participate and/or certain of the participating Member States may decide to withdraw.

Prospective holders of the notes are advised to seek their own professional advice in relation to the FTT.

S-24

UNDERWRITING

We are offering the notes described in this prospectus supplement through the underwriters named below, for whom BNP Paribas, Deutsche Bank AG, London Branch, J.P. Morgan Securities plc, Merrill Lynch International and UniCredit Bank GmbH are acting as representatives. We have entered into a firm commitment underwriting agreement with the underwriters. Subject to the terms and conditions of the underwriting agreement, we have agreed to sell to the underwriters, and each underwriter has severally, and not jointly, agreed to purchase, the aggregate principal amount of notes listed next to its name in the following table:

Underwriter	Principal Amount of 20  Fixed Rate Notes		Principal Amount of 20  Fixed Rate Notes
BNP Paribas	€		€
Deutsche Bank AG, London Branch
J.P. Morgan Securities plc
Merrill Lynch International
UniCredit Bank GmbH
Total	€		€

The underwriting agreement is subject to a number of terms and conditions and provides that the underwriters must buy all of the notes if they buy any of them. The underwriters will sell the notes to the public when and if the underwriters buy the notes from us. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

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

To the extent any underwriter that is not a U.S.-registered broker-dealer intends to effect sales of notes in the United States, it will do so through one or more U.S.-registered broker-dealers in accordance with the applicable U.S. securities laws and regulations and the rules of FINRA.

Commissions and Discounts

The underwriters have advised us that they propose initially to offer the notes to the public for cash at the public offering prices set forth on the cover of this prospectus supplement, and to certain dealers at such prices less concessions not in excess of % of the principal amount of the 20  fixed rate notes and less concessions not in excess of  % of the principal amount of the 20  fixed rate notes. The underwriters may allow, and such dealers may reallow, a concession not in excess of  % of the principal amount of the 20  fixed rate notes and not in excess of  % of the principal amount of the 20  fixed rate notes. After the initial public offering of the notes, the public offering price and other selling terms may be changed.

We estimate that our share of the total expenses of the offering, excluding underwriting discounts, will be approximately €   .

New Issue of Notes

Each series of the notes is a new issue of securities, and there is currently no established trading market for any series of the notes offered hereby. We intend to apply to list each series of the notes on Nasdaq. We expect trading to begin within 30 days after the original issue date. Currently there is no public market for each series of the notes. If such a listing is obtained, we have no obligation to maintain such listing, and we may delist any series of the notes at any time. Although the underwriters have advised us that certain of them intend to make a

S-25

market in the notes, they are not obligated to do so. The underwriters may discontinue any market-making in the notes of any series at any time without notice in their sole discretion. Therefore, we cannot assure you that a liquid trading market will develop for any series of notes, that you will be able to sell your notes of any series at a particular time or that the prices that you receive when you sell will be favorable.

Price Stabilization and Penalty Bids

In connection with this offering, J.P. Morgan Securities plc (the “stabilizing manager”) (or any person acting on its behalf), may over-allot notes or effect transactions which stabilize or maintain the market price of the notes at levels which might not otherwise prevail. This stabilizing, if commenced, may be discontinued at any time. Any stabilization action or over-allotment will be conducted by the stabilizing manager (or any person acting on behalf of the stabilizing manager) in accordance with all applicable laws and rules. There is no assurance that the stabilizing manager (or any person acting on behalf of the stabilizing manager) will undertake any stabilization action. Any stabilization action may 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.

The underwriters also may impose a penalty bid. Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the underwriters, in covering syndicate short positions or making stabilizing purchases, repurchase notes originally sold by that syndicate member.

Any of these activities may have the effect of preventing or retarding a decline in the market prices of the notes. They may also cause the prices of the notes to be higher than the prices 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.

Other Relationships

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. The underwriters and their affiliates may have engaged in, and may in the future engage in, investment banking, commercial banking and other commercial dealings in the ordinary course of business with us. They have received, and in the future may receive, customary fees and commissions for these transactions. In the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers, and such investment and securities activities may involve securities and/or instruments of ours or our affiliates. If any of the underwriters or their affiliates have a lending relationship with us, certain of those underwriters or their affiliates routinely hedge, and certain other of those underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, these 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 respective affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments. An affiliate of one of the underwriters is the trustee. We expect that certain of the underwriters in this offering will also act as underwriters in any Concurrent Offering.

S-26

T+4 Settlement

We expect that delivery of the notes will be made to investors on or about the fourth business day following the date of this prospectus supplement (such settlement being referred to as “T+4”). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market are generally required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes more than two business days prior to their date of delivery will be required, by virtue of the fact that the notes initially settle in T+4, to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement and should consult their own advisors.

Selling Restrictions

Prohibition of Sales to European Economic Area Retail Investors

Each underwriter has represented and agreed that it has not offered, sold or otherwise made available and will not offer, sell, or otherwise make available any notes to any retail investor in the European Economic Area (“EEA”). For these purposes,

(a) 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, 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 Regulation (EU) 2017/1129 (as amended, the “Prospectus Regulation”); 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 notes to be offered so as to enable an investor to decide to purchase or subscribe for the notes.

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

S-27

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 has been prepared on the basis that any offer of the 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 the notes. This prospectus supplement is not a prospectus for the purposes of the Prospectus Regulation.

Prohibition of Sales to United Kingdom Retail Investors

Each underwriter has represented and agreed that it has not offered, sold or otherwise made available and will not offer, sell or otherwise make available any notes to any retail investor in the United Kingdom (“UK”)). For these purposes,

(a) 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 UK domestic law by virtue of the European Union (Withdrawal) Act 2018 (the “EUWA”); or

(ii) a customer within the meaning of the provisions of the Financial Services and Markets Act 2000 (as amended, the “FSMA”) and any rules or regulations made under the FSMA to implement Directive (EU) 2016/97, where that customer would not qualify as a professional client, as defined in point (8) of Article 2 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 UK domestic law by virtue of the EUWA (the “UK Prospectus Regulation”); 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 notes to be offered so as to enable an investor to decide to purchase or subscribe for the notes.

Consequently, no key information document required by Regulation (EU) No 1286/2014 as it forms part of domestic law by virtue of the EUWA (the “UK PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the UK has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the UK may be unlawful under the UK PRIIPs Regulation. This prospectus supplement and the accompanying prospectus have been prepared on the basis that any offer of the notes in the UK will be made pursuant to an exemption under the UK Prospectus Regulation from the requirement to publish a prospectus for offers of the notes.

General

The debt securities that we may offer under the indenture are not limited in aggregate principal amount. We may issue debt securities at one or more times in one or more series.

Additional debt securities of a particular series will have the same terms and conditions as outstanding debt securities of such series, except for the date of original issuance and the offering price, and will be consolidated with, and form a single series with, such outstanding debt securities.

The debt securities will be unsecured obligations and will rank equally with all of our other unsecured senior indebtedness.

Covenants

Except as described below or in the prospectus supplement with respect to any series of debt securities, we are not restricted by the indenture from incurring, assuming or becoming liable for any type of debt or other obligations, from paying dividends or making distributions on our capital stock or purchasing or redeeming our capital stock. The indenture does not require the maintenance of any financial ratios or specified levels of net worth or liquidity. In addition, with certain exceptions, the indenture does not contain any covenants or other

3

provisions that would limit our right to incur additional indebtedness. The indenture does not contain any provisions that would require us to repurchase or redeem or otherwise modify the terms of any of the debt securities upon a change in control or other events that may adversely affect the creditworthiness of the debt securities, such as for example, a highly leveraged transaction.

Unless otherwise indicated in the prospectus supplement, covenants contained in the indenture, which are summarized below, will be applicable to the series of debt securities to which the prospectus supplement relates so long as any of the debt securities of that series are outstanding.

Limitation on Mortgages. In the indenture, we covenant not to issue, assume or guarantee any indebtedness for borrowed money secured by liens on:

• any property located in the United States which is in the opinion of our board of directors, a principal manufacturing property; or

• any shares of capital stock or indebtedness of any subsidiary owning such property, without equally and ratably securing the debt securities, subject to exceptions specified in the indenture. These exceptions include:

• existing liens on our property or liens on property of corporations at the time those corporations become our subsidiaries or are merged with us;

• liens existing on property when acquired, or incurred to finance the purchase price of that property;

• certain liens on property to secure the cost of development of, or improvements on, that property;

• certain liens in favor of or required by contracts with governmental entities; and

• indebtedness secured by liens otherwise prohibited by the covenant not exceeding 10% of the consolidated net tangible assets of Honeywell and our consolidated subsidiaries.

Limitation on Sale and Lease-Back. We also covenant not to enter into any sale and lease-back transaction covering any property located in the United States which is in the opinion of our board of directors, a principal manufacturing property, unless:

• we would be entitled under the provisions described under “—Limitation on Liens” to incur debt equal to the value of such sale and lease-back transaction, secured by liens on the property to be leased, without equally securing the outstanding debt securities; or

• we, during the four months following the effective date of such sale and lease-back transaction, apply an amount equal to the value of such sale and lease-back transaction to the voluntary retirement of long-term indebtedness of Honeywell or our subsidiaries.

Consolidation, Merger and Sale of Assets. The indenture provides that we may not consolidate with or merge into any other person or sell our assets substantially as an entirety, unless:

• the person formed by such consolidation or into which we are merged or the person which acquires our assets is a person organized in the United States of America and expressly assumes the due and punctual payment of the principal of and interest on all the debt securities and the performance of every covenant of the indenture on our part;

• immediately after giving effect to such transaction, no event of default, and no event which, after notice or lapse of time, or both, would become an event of default, shall have happened and be continuing; and

• we have delivered to the trustee an officers’ certificate and an opinion of counsel each stating that such consolidation or transfer and a supplemental indenture, if applicable, comply with the indenture and that all conditions precedent herein provided for relating to such transaction have been complied with.

4

Upon such consolidation, merger or sale, the successor corporation formed by such consolidation or into which we are merged or to which such sale is made will succeed to, and be substituted for, us under the indenture, and the predecessor corporation shall be released from all obligations and covenants under the indenture and the debt securities.

The indenture does not restrict, or require us to redeem or permit holders to cause redemption of debt securities in the event of:

• a consolidation, merger, sale of assets or other similar transaction that may adversely affect our creditworthiness or the successor or combined entity;

• a change in control of us; or

• a highly leveraged transaction involving us whether or not involving a change in control.

Accordingly, the holders of debt securities would not have protection in the event of a highly leveraged transaction, reorganization, restructuring, merger or similar transaction involving us that may adversely affect the holders. The existing protective covenants applicable to the debt securities would continue to apply to us in the event of a leveraged buyout initiated or supported by us, our management, or any of our affiliates or their management, but may not prevent such a transaction from taking place.

Events of Default, Notice and Waiver

The indenture provides that if an event of default shall have occurred and be continuing with respect to any series of debt securities, then either the trustee or the holders of not less than 25% in outstanding principal amount of the debt securities of that series may declare to be due and payable immediately the outstanding principal amount of the debt securities of the affected series, together with interest, if any, accrued thereon; provided, however, that if the event of default is any of certain events of bankruptcy, insolvency or reorganization, all the debt securities, together with interest, if any, accrued thereon, will become immediately due and payable without further action or notice on the part of the trustee or the holders.

Under the indenture, an event of default with respect to the debt securities of any series is any one of the following events:

(1) default for 30 days in payment when due of any interest due with respect to the debt securities of such series;

(2) default in payment when due of principal of or of premium, if any, on the debt securities of such series;

(3) default in the observance or performance of any other covenant or agreement contained in the indenture which default continues for a period of 90 days after we receive written notice specifying the default (and demanding that such default be remedied) from the trustee or the holders of at least 25% of the principal amount of securities of that series then outstanding (with a copy to the trustee if given by holders) (except in the case of a default with respect to certain consolidations, mergers, or sales of assets as set forth in Section 10.01 of the indenture, which will constitute an event of default with such notice requirement but without such passage of time requirement), provided, however, that the sole remedy of holders of the securities for an event of default relating to the failure to file any documents or reports that Honeywell is required to file with the SEC pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934, as amended, and for any failure to comply with the requirements of Section 314(a)(1) of the Trust Indenture Act of 1939, as amended, which we refer to as the Trust Indenture Act, to provide such documents or reports, within 30 days after filing with the SEC, to the trustee pursuant to Section 14.04 of the indenture, will for the first 60 days after the occurrence of such an event of default, or such shorter period until such event of default has been cured or waived, consist exclusively of the right to receive additional interest on the securities at an annual rate equal to 0.25%

5

of the outstanding principal amount of the securities, and that, on the 61st day after such event of default (if such event of default is not cured or waived prior to such 61st day), the securities will be subject to acceleration as provided in the indenture;

(4) certain events of bankruptcy, insolvency and reorganization; and

(5) any other event of default provided with respect to debt securities of that series.

The indenture provides that the trustee will, within 90 days after the occurrence of a default with respect to the debt securities of any series, give to the holders of debt securities of such series notice of such default known to it, unless cured or waived; provided that except in the case of default in the payment of principal, or interest or premium, if any, on any debt security of such series or in the payment of any sinking fund installment with respect to debt securities of such series, the trustee will be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust committee of directors and/or specified officers of the trustee in good faith determine that the withholding of such notice is in the interests of the holders of debt securities of such series. The term “default” for the purpose of this provision means any event that is, or after notice or lapse of time, or both, would become, an event of default.

The indenture contains a provision entitling the trustee, subject to the duty of the trustee during the continuance of an event of default to act with the required standard of care, to be indemnified by the holders before proceeding to exercise any right or power under the indenture at the request of such holders. The indenture provides that the holders of a majority in outstanding principal amount of the debt securities of any series may, subject to certain exceptions, on behalf of the holders of debt securities of such series direct the time, method and place of conducting proceedings for remedies available to the trustee, or exercising any trust or power conferred on the trustee.

The indenture includes a covenant that we will file annually with the trustee a certificate of no default, or specifying any default that exists.

In certain cases, the holders of a majority in outstanding principal amount of the debt securities of any series may on behalf of the holders of debt securities of such series rescind a declaration of acceleration or waive any past default or event of default with respect to the debt securities of that series except a default not theretofore cured in payment of the principal of, or interest or premium, if any, on any debt security of such series or in respect of a provision which under the indenture cannot be modified or amended without the consent of the holder of each such debt security.

No holder of a debt security of any series will have any right to institute any proceeding with respect to the indenture or the debt securities of any series or for any remedy thereunder unless:

• such holder shall have previously given to the trustee written notice of a continuing event of default;

• the holders of at least 25% in aggregate principal amount of the outstanding debt securities of such series have also made such a written request;

• such holder or holders have provided indemnity satisfactory to the trustee to institute such proceeding as trustee;

• the trustee has not received from the holders of a majority in outstanding principal amount of the debt securities of such series a direction inconsistent with such request; and

• the trustee has failed to institute such proceeding within 90 calendar days of such notice.

However, such limitations do not apply to a suit instituted by a holder of debt securities for enforcement of payment of the principal of, or premium or interest, if any, on such debt securities on or after the respective due dates expressed in such debt securities after any applicable grace periods have expired.

6

Modification and Waiver

The trustee and we may amend or supplement the indenture or the debt securities of any series without the consent of any holder, in order to:

• cure any ambiguity, defect or inconsistency;

• provide for uncertificated debt securities in addition to or in place of certificated debt securities;

• provide for the assumption of our obligations to the holders in the case of a merger or consolidation of us as permitted by the indenture;

• evidence and provide for the acceptance of appointment by a successor trustee and to add to or change any of the provisions of the indenture as are necessary to provide for or facilitate the administration of the trusts by more than one trustee;

• make any change that would provide any additional rights or benefits to the holders of all or any series of debt securities and that does not adversely affect any such holder; or

• comply with SEC requirements in order to effect or maintain the qualification of the indenture under the Trust Indenture Act.

In addition, except as described below, modifications and amendments of the indenture or the debt securities of any series may be made by the trustee and us with the consent of the holders of a majority in outstanding principal amount of the debt securities affected by such modification or amendment. However, no such modification or amendment may, without the consent of each holder affected thereby:

• change the stated maturity of, or time for payment of interest on, any debt security;

• reduce the principal amount of, or the rate of interest or the premium, payable upon the redemption of, if any, on any debt security;

• change the place or currency of payment of principal of, or interest or premium, if any, on any debt security;

• impair the right to institute suit for the enforcement of any payment on or with respect to such debt securities on or after the stated maturity or prepayment date thereof; or

• reduce the percentage in principal amount of debt securities of any series where holders must consent to an amendment, supplement or waiver.

Defeasance

The indenture provides that we will be discharged from any and all obligations in respect of the debt securities of any series (except for certain obligations to register the transfer or exchange of the debt securities, to replace stolen, lost or mutilated debt securities, to maintain paying agencies and hold monies for payment in trust and to pay the principal of and interest, if any, on such debt securities), upon the irrevocable deposit with the trustee, in trust, of money and/or U.S. government securities, which through the payment of interest and principal thereof in accordance with their terms provides money in an amount sufficient to pay the principal of (and premium, if any) and interest, if any, in respect of the debt securities of such series on the stated maturity date of such principal and any installment of principal, or interest or premium, if any. Also, the establishment of such a trust will be conditioned on the delivery by us to the trustee of an opinion of counsel reasonably satisfactory to the trustee to the effect that, based upon applicable U.S. federal income tax law or a ruling published by the United States Internal Revenue Service, such a defeasance and discharge will not be deemed, or result in, a taxable event with respect to the holders. For the avoidance of doubt, such an opinion would require a change in current U.S. tax law.

We may also omit to comply with the restrictive covenants, if any, of any particular series of debt securities, other than our covenant to pay the amounts due and owing with respect to such series of debt securities.

7

Thereafter, any such omission shall not be an event of default with respect to the debt securities of such series, upon the deposit with the trustee, in trust, of money and/or U.S. government securities which through the payment of interest and principal in respect thereof in accordance with their terms provides money in an amount sufficient to pay any installment of principal of (and premium, if any) and interest, if any, in respect of debt securities of such series on the stated maturity date of such principal or installment of principal, or interest or premium, if any. Our obligations under the indenture and the debt securities of such series other than with respect to such covenants shall remain in full force and effect. Also, the establishment of such a trust will be conditioned on the delivery by us to the trustee of an opinion of counsel to the effect that such a defeasance and discharge will not be deemed, or result in, a taxable event with respect to the holders.

In the event we exercise our option to omit compliance with certain covenants as described in the preceding paragraph and the debt securities of such series are declared due and payable because of the occurrence of any event of default, then the amount of monies and U.S. government securities on deposit with the trustee will be sufficient to pay amounts due on the debt securities of such series at the time of the acceleration resulting from such event of default. We shall in any event remain liable for such payments as provided in the debt securities of such series.

Satisfaction and Discharge

At our option, we may satisfy and discharge the indenture with respect to the debt securities of any series (except for specified obligations of the trustee and ours, including, among others, the obligations to apply money held in trust) when:

• either (a) all debt securities of such series previously authenticated and delivered under the indenture have been delivered to the trustee for cancellation or (b) all debt securities of such series not theretofore delivered to the trustee for cancellation have become due and payable, will become due and payable at their stated maturity within one year, or are to be called for redemption within one year under arrangements satisfactory to the trustee for the giving of notice of redemption by the trustee, and we have deposited or caused to be deposited with the trustee as trust funds in trust for such purpose an amount sufficient to pay and discharge the entire indebtedness on debt securities of such series;

• we have paid or caused to be paid all other sums payable under the indenture with respect to the debt securities of such series by us; and

• we have delivered to the trustee an officers’ certificate and an opinion of counsel, each to the effect that all conditions precedent relating to the satisfaction and discharge of the indenture as to such series have been satisfied.

Regarding the Trustee

The indenture contains certain limitations on the right of the trustee, should it become a creditor of ours within three months of, or subsequent to, a default by us to make payment in full of principal of or interest on any series of debt securities issued pursuant to the indenture when and as the same becomes due and payable, to obtain payment of claims, or to realize for its own account on property received in respect of any such claim as security or otherwise, unless and until such default is cured. However, the trustee’s rights as a creditor of ours will not be limited if the creditor relationship arises from, among other things:

• the ownership or acquisition of securities issued under any indenture or having a maturity of one year or more at the time of acquisition by the trustee;

• certain advances authorized by a receivership or bankruptcy court of competent jurisdiction or by the indenture;

• disbursements made in the ordinary course of business in its capacity as indenture trustee, transfer agent, registrar, custodian or paying agent or in any other similar capacity;

8

• indebtedness created as a result of goods or securities sold in a cash transaction or services rendered or premises rented; or

• the acquisition, ownership, acceptance or negotiation of certain drafts, bills of exchange, acceptances or other obligations.

The indenture does not prohibit the trustee from serving as trustee under any other indenture to which we may be a party from time to time or from engaging in other transactions with us. If the trustee acquires any conflicting interest within the meaning of the Trust Indenture Act and any debt securities issued pursuant to the indenture are in default, it must eliminate such conflict or resign.

DESCRIPTION OF PREFERRED STOCK

General

Honeywell’s amended and restated certificate of incorporation, or charter, authorizes the board of directors or a committee of the board of directors to cause preferred stock to be issued in one or more series, without stockholder action. They are authorized to issue up to 40,000,000 shares of preferred stock, without par value, and can determine the number of shares of each series, and the rights, preferences and limitations of each series. We may amend the charter to increase the number of authorized shares of preferred stock in a manner permitted by the charter and Delaware law. As of the date of this prospectus, there is no preferred stock outstanding.

The particular terms of any series of preferred stock offered by us or by a selling security holder will be described in the prospectus supplement relating to that series of preferred stock. Those terms relating to the series of preferred stock offered may include:

• the number of shares of the preferred stock being offered;

• the title and liquidation preference per share of the preferred stock;

• the purchase price of the preferred stock;

• the dividend rate or method for determining the dividend rate;

• the dates on which dividends will be paid;

• whether dividends on the preferred stock will be cumulative or noncumulative and, if cumulative, the dates from which dividends shall commence to accumulate;

• any redemption or sinking fund provisions applicable to the preferred stock;

• the identity of any selling security holder;

• any securities exchange on which the preferred stock may be listed; and

• any additional dividend, liquidation, redemption, sinking fund and other rights and restrictions applicable to the preferred stock.

The following summary is not complete. You should refer to the certificate of designations relating to any series of preferred stock for the complete terms of that preferred stock. The certificate of designations will be filed with the SEC at the time of the offering of the preferred stock. Unless otherwise specified in the prospectus supplement, if we liquidate, dissolve or wind-up our business, each series of preferred stock will have the same rank as to dividends and distributions as each other series of preferred stock we may issue in the future. Preferred stock will have no preemptive rights.

Dividend Rights

Holders of preferred stock will be entitled to receive, when, as and if declared by the board of directors, cash dividends at the rates and on the dates set forth in the related prospectus supplement. Dividend rates may be fixed or variable or both. Different series of preferred stock may be entitled to dividends at different dividend rates or based upon different methods of determination. Each dividend will be payable to the holders of record as they appear on our stock books on record dates determined by the board of directors. Dividends on preferred stock may be cumulative or noncumulative, as specified in the related prospectus supplement. If the board of directors fails to declare a dividend on any preferred stock for which dividends are noncumulative, then the right to receive that dividend will be lost, and we will have no obligation to pay the dividend for that dividend period, whether or not dividends are declared for any future dividend period.

When those dividends are not paid in full, dividends will be declared pro rata, so that the amount of dividends declared per share on that series of preferred stock and on each other series of preferred stock having

the same rank as that series of preferred stock will bear the same ratio to each other that accrued dividends per

10

share on that series of preferred stock and the other series of preferred stock bear to each other. In addition, generally, unless full dividends including any cumulative dividends still owing on all outstanding shares of any series of preferred stock have been paid, no dividends will be declared or paid on the common stock and generally we may not redeem or purchase any common stock. No interest will be paid in connection with any dividend payment or payments which may be in arrears.

Unless otherwise set forth in the related prospectus supplement, the dividends payable for each dividend period will be computed by annualizing the applicable dividend rate and dividing by the number of dividend periods in a year, except that the amount of dividends payable for the initial dividend period or any period shorter than a full dividend period will be computed on the basis of a 360-day year consisting of twelve 30-day months and, for any period less than a full month, the actual number of days elapsed in the period.

Rights Upon Liquidation

If we liquidate, dissolve or wind-up our affairs, either voluntarily or involuntarily, the holders of each series of preferred stock will be entitled to receive liquidating distributions in the amount set forth in the prospectus supplement relating to the series of preferred stock, plus an amount equal to any accrued and unpaid dividends before any distribution of assets is made to the holders of common stock. If the amounts payable with respect to preferred stock of any series and any stock having the same rank as that series of preferred stock are not paid in full, the holders of the preferred stock will share ratably in any such distribution of assets in proportion to the full respective preferential amounts to which they are entitled. After the holders of each series of preferred stock having the same rank are paid in full, they will have no right or claim to any of our remaining assets. Neither the sale of all or substantially all of our property or business nor a merger or consolidation by us with any other corporation will be considered a dissolution, liquidation or winding up by us of our business or affairs.

Redemption

Any series of preferred stock may be redeemable in whole or in part at our option. In addition, any series of preferred stock may be subject to mandatory redemption pursuant to a sinking fund. The redemption provisions that may apply to a series of preferred stock, including the redemption dates and the redemption prices for that series, will be set forth in the related prospectus supplement.

If a series of preferred stock is subject to mandatory redemption, the related prospectus supplement will specify the year we can begin to redeem shares of the preferred stock, the number of shares of the preferred stock we can redeem each year, and the redemption price per share. We may pay the redemption price in cash, stock or other securities of Honeywell or of third parties, as specified in the related prospectus supplement. If the redemption price is to be paid only from the proceeds of the sale of our capital stock, the terms of the series of preferred stock may also provide that if no capital stock is sold or if the amount of cash received is insufficient to pay in full the redemption price then due, the series of preferred stock will automatically be converted into shares of the applicable capital stock pursuant to conversion provisions specified in the related prospectus supplement.

If fewer than all the outstanding shares of any series of preferred stock are to be redeemed, whether by mandatory or optional redemption, the board of directors will determine the method for selecting the shares to be redeemed, which may be by lot or pro rata by any other method determined to be equitable. From and after the redemption date, dividends will cease to accrue on the shares of preferred stock called for redemption and all rights of the holders of those shares other than the right to receive the redemption price will cease.

Conversion Rights

The related prospectus supplement will state any conversion rights under which shares of preferred stock are convertible into shares of common stock or another series of preferred stock or other property. As described under “—Redemption” above, under some circumstances preferred stock may be mandatorily converted into common stock or another series of preferred stock.

11

Voting Rights

For most series of preferred stock, the holders of preferred stock will generally not be entitled to vote. Except as indicated in the related prospectus supplement, if we issue full shares of any series of preferred stock, each share will be entitled to one vote on matters on which holders of that series of preferred stock are entitled to vote. Because each full share of any series of preferred stock will be entitled to one vote, the voting power of that series will depend on the number of shares in that series, and not on the aggregate liquidation preference or initial offering price of the shares of that series of preferred stock.

Transfer Agent and Registrar

We will appoint a transfer agent, registrar and dividend disbursement agent for the preferred stock. The registrar for the preferred stock will send notices to the holders of the preferred stock of any meeting at which those holders will have the right to elect directors or to vote on any other matter.

Permanent Global Preferred Securities

A series of preferred stock may be issued in whole or in part in the form of one or more global securities that will be deposited with a depositary or its nominee identified in the related prospectus supplement. For most series of preferred stock, the depositary will be DTC (as defined herein). A global security may not be transferred except as a whole to the depositary, a nominee of the depositary or their successors unless it is exchanged in whole or in part for preferred stock in individually certificated form. For a description of the depositary arrangements, see “Book-Entry Issuance.” Any additional terms of the depositary arrangement with respect to any series of preferred stock and the rights of and limitations on owners of beneficial interests in a global security representing a series of preferred stock may be described in the related prospectus supplement.

12

DESCRIPTION OF COMMON STOCK

General

As of the date of this prospectus, we are authorized to issue up to 2,000,000,000 shares of common stock. As of September 30, 2021, we had approximately 958 million shares of common stock issued (including approximately 269.2 million shares held in treasury). EQ Shareowner Services, a division of Equiniti Trust Company, is the transfer agent and registrar for our common stock. Shares of common stock are listed on the Nasdaq Stock Market and the London Stock Exchange under the symbol “HON.”

The following summary is not complete. You should refer to the applicable provision of Honeywell’s charter and by-laws and to Delaware corporate law for a complete statement of the terms and rights of our common stock.

Dividends

Holders of common stock are entitled to receive dividends when, as and if declared by the board of directors, out of funds legally available for their payment, subject to the rights of holders of any preferred stock outstanding.

Voting Rights

Each holder of common stock is entitled to one vote per share. Subject to any rights of the holders of any series of preferred stock pursuant to applicable law or the provision of the certificate of designations creating that series, all voting rights are vested in the holders of shares of common stock. Holders of shares of common stock have noncumulative voting rights, which means that the holders of more than 50% of the shares voting for the election of directors can elect 100% of the directors, and the holders of the remaining shares voting for the election of directors will not be able to elect any directors.

Rights Upon Liquidation

In the event of Honeywell’s voluntary or involuntary liquidation, dissolution or winding up, the holders of common stock will be entitled to share equally in any of Honeywell’s assets available for distribution after the payment in full of all debts and distributions and after the holders of any series of outstanding preferred stock have received their liquidation preferences in full.

Other Rights

Holders of shares of common stock are not entitled to preemptive rights. Shares of common stock are not convertible into shares of any other class of capital stock. If we merge or consolidate with or into another company and as a result our common stock is converted into or exchangeable for shares of stock, other securities or property (including cash), all holders of common stock will be entitled to receive the same kind and amount of consideration per share of common stock.

Possible Anti-Takeover Provisions

Honeywell’s charter and by-laws provide:

• that the board of directors may establish the number of seats on the board, subject to the right of preferred stockholders to elect directors in certain circumstances and shareowners’ rights to set the number of seats upon the vote of holders of a majority of the outstanding shares of common stock;

• that vacancies on the board of directors other than at the annual meeting are filled by a vote of the remaining directors;

13

• that special meetings of shareowners generally may be called only by the chief executive officer, by a majority of the authorized number of directors, or by the holders of not less than fifteen percent of the outstanding shares of Honeywell’s common stock (excluding derivatives);

• that action may be taken by shareowners only at annual or special meetings and not by written consent;

• that advance notice must be given to Honeywell for a shareowner to nominate directors for election at a shareowner meeting; and

• that the board of directors may in limited circumstances, without stockholder approval, adopt a plan to provide for the distribution to stockholders of preferred stock or certain other securities upon the occurrence of certain triggering events (but any such plan adopted without stockholder approval must expire within one year of adoption unless ratified by the stockholders).

Any of these provisions could delay, deter or prevent a tender offer for or attempted takeover of Honeywell.

Our charter permits us to issue up to 40,000,000 shares of preferred stock with terms that may be set by our board of directors or a committee of the board. That preferred stock could have terms that could delay, deter or prevent a tender offer or takeover attempt of Honeywell.

Under Delaware law, an acquirer of 15% or more of our shares of stock must wait three years before a business combination with us unless one of the following exceptions is available:

• approval by our board of directors prior to the time the acquirer became a 15% shareowner of Honeywell;

• acquisition of at least 85% of our voting stock in the transaction in which the acquirer became a 15% shareowner of Honeywell; or

• approval of the business combination by our board of directors and two-thirds of our disinterested shareowners.

Honeywell’s by-laws provide that, unless Honeywell consents in writing to the selection of an alternative forum, a state or federal court located within the State of Delaware will be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of Honeywell, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of Honeywell to Honeywell or Honeywell’s stockholders, (iii) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law or (iv) any action asserting a claim governed by the internal affairs doctrine. Honeywell’s by-laws also provide that any person or entity purchasing or otherwise acquiring any interest in shares of capital stock of Honeywell will be deemed to have notice of and consented to the exclusive forum provisions described above.

14

BOOK-ENTRY ISSUANCE

Our common stock is cleared and settled though the Depositary Trust Company, or DTC, a securities depositary. Most series of debt securities and preferred stock will also be book-entry securities. Upon issuance, unless otherwise specified in the prospectus supplement, all book-entry securities of the same series will be represented by one or more fully registered global securities. Each global security will be deposited with, or on behalf of, DTC and will be registered in the name of DTC or a nominee of DTC. DTC will thus be the only registered holder of any such securities and will be considered the sole owner of the securities.

Purchasers may only hold interests in the global securities through DTC if they are participants in the DTC system. Purchasers may also hold interests through a securities intermediary–a bank, brokerage house or other institution that maintains securities accounts for customers–that has an account with DTC or its nominee. DTC will maintain accounts showing the securities holdings of its participants, and these participants will in turn maintain accounts showing the securities holdings of their customers. Some of these customers may themselves be securities intermediaries holding securities for their customers. Thus, each beneficial owner of a book-entry security will hold that security indirectly through a hierarchy of intermediaries, with DTC at the “top” and the beneficial owner’s own securities intermediary at the “bottom.”

The securities of each beneficial owner of a book-entry security will be evidenced solely by entries on the books of the beneficial owner’s securities intermediary. The actual purchaser of the securities will generally not be entitled to have the securities represented by the global securities registered in its name and will not be considered the owner. In most cases, a beneficial owner will also not be able to obtain a paper certificate evidencing the holder’s ownership of securities. The book-entry system for holding securities eliminates the need for physical movement of certificates. The laws of some jurisdictions require some purchasers of securities to take physical delivery of their securities in definitive form. These laws may impair the ability to transfer book-entry securities.

Unless otherwise specified in the prospectus supplement with respect to a series of debt securities or preferred stock, beneficial owners of book-entry securities represented by a global security may exchange the securities for definitive or paper securities only if:

• DTC is unwilling or unable to continue as depositary for such global security and Honeywell is unable to find a qualified replacement for DTC within 90 days;

• at any time DTC ceases to be a “clearing agency” registered under the Securities Exchange Act of 1934, as amended; or

• Honeywell in its sole discretion decides to allow some or all book-entry securities to be exchangeable for definitive securities in registered form.

Any global security that is exchangeable will be exchangeable in whole for definitive securities in registered form with the same terms, and in the case of debt securities, in an equal aggregate principal amount in denominations of $1,000 and whole multiples of $1,000 (unless otherwise specified in the prospectus supplement). Definitive securities will be registered in the name or names of the person or persons specified by DTC in a written instruction to the registrar of the securities. DTC may base its written instruction upon directions it receives from its participants.

In this prospectus and the accompanying prospectus supplement, for book-entry securities, references to actions taken by security holders will mean actions taken by DTC upon instructions from its participants, and references to payments and notices of redemption to security holders will mean payments and notices of redemption to DTC as the registered holder of the securities for distribution to participants in accordance with DTC’s procedures.

15

DTC is a limited-purpose trust company organized under the laws of the State of New York, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a

“clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered under the Securities Exchange Act of 1934, as amended. The rules applicable to DTC and its participants are on file with the SEC.

Honeywell will not have any responsibility or liability for any aspect of the records relating to, or payments made on account of, beneficial ownership interests in the book-entry securities or for maintaining, supervising or reviewing any records relating to the beneficial ownership interests.

16

PLAN OF DISTRIBUTION

We may sell our debt securities, or we or one or more selling security holders to be identified in a prospectus supplement may sell our preferred or common stock:

• to or through underwriters or dealers for resale;

• to or through agents;

• directly to other purchasers;

• through any combination of these methods; or

• through any other means described in a prospectus supplement.

The related prospectus supplement will set forth the terms of the offering of the securities, including the following:

• the name or names of any underwriters, dealers or agents;

• the purchase price and the proceeds we will receive from the sale;

• the identity of any selling security holder;

• any underwriting discounts and other items constituting underwriters’ compensation; and

• any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers.

If underwriters are used in the sale, the securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The securities may be either offered to the public through underwriting syndicates represented by managing underwriters or by underwriters without a syndicate. The obligations of the underwriters to purchase securities will be subject to conditions precedent and the underwriters will be obligated to purchase all the securities of a series if any are purchased. Any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.

Securities may be sold directly by us or by one or more selling security holders or through agents designated by us or one or more selling security holders from time to time. Any agent involved in the offer or sale of the securities in respect of which this prospectus is delivered will be named, and any commissions payable by us or by any selling security holders to that agent will be set forth, in the related prospectus supplement. Unless otherwise indicated in the related prospectus supplement, any agent will be acting on a best efforts basis for the period of its appointment.

We may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement so indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale transactions will be an underwriter and will be identified in the applicable prospectus supplement.

Unless otherwise specified in an applicable prospectus supplement, each series of debt securities or preferred stock will be a new issue of securities with no established trading market. Underwriters and agents may from time to time purchase and sell the securities described in this prospectus and the relevant prospectus

17

supplement in the secondary market, but are not obligated to do so. No assurance can be given that there will be a secondary market for the securities or liquidity in the secondary market if one develops. From time to time, underwriters and dealers may make a market in the securities.

In order to facilitate the offering of the securities, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of these securities or any other securities the prices of which may be used to determine payments on these securities. Specifically, the underwriters may over-allot in connection with the offering, creating a short position in the securities for their own accounts. In addition, to cover over-allotments or to stabilize the price of the securities or of any other securities, the underwriters may bid for, and purchase, the securities or any other securities in the open market. Finally, in any offering of the securities through a syndicate of underwriters, the underwriting syndicate may reclaim selling concessions allowed to an underwriter or a dealer for distributing the securities in the offering, if the syndicate repurchases previously distributed securities in transactions to cover syndicate short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the securities above independent market levels. The underwriters are not required to engage in these activities, and may end any of these activities at any time.

Underwriters named in a prospectus supplement are, and dealers and agents named in a prospectus supplement may be, deemed to be “underwriters” within the meaning of the Securities Act of 1933, as amended, which we refer to as the Securities Act, in connection with the securities offered thereby, and any discounts or commissions they receive from us or any selling security holder and any profit on their resale of the securities may be deemed to be underwriting discounts and commissions under the Securities Act.

One or more firms, referred to as “remarketing firms,” may also offer or sell the securities, if the prospectus supplement so indicates, in connection with a remarketing arrangement upon their purchase. Remarketing firms will act as principals for their own accounts or as agents for us or any identified selling security holder. These remarketing firms will offer or sell the securities in accordance with a redemption or repayment pursuant to the terms of the securities. The prospectus supplement will identify any remarketing firm and the terms of its agreement, if any, with us or any identified selling security holder and will describe the remarketing firm’s compensation. Remarketing firms may be deemed to be underwriters in connection with the securities they remarket. Remarketing firms may be entitled under agreements that may be entered into with us or any such selling security holder to indemnification by us or any such selling security holder against certain civil liabilities, including liabilities under the Securities Act and may be customers of, engage in transactions with or perform services for us in the ordinary course of business.

Unless indicated in the applicable prospectus supplement, we do not expect to apply to list the debt securities or preferred stock on a securities exchange. Any common stock sold pursuant to a prospectus supplement will be listed on the exchanges where our common stock is then listed, subject to notice of issuance.

Agents and underwriters may be entitled to indemnification by us against civil liabilities arising out of this prospectus, including liabilities under the Securities Act, or to contribution with respect to payments which the agents or underwriters may be required to make relating to those liabilities.

Agents and underwriters may be engaged in transactions with, or perform commercial or investment banking or other services for, us or our subsidiaries or affiliates, in the ordinary course of business.

We will estimate our expenses associated with any offering of debt securities, preferred stock or common stock in the prospectus supplement relating to such offering.
