The second part is the accompanying prospectus dated October 22, 2021, which we refer to as the “accompanying prospectus.” The accompanying prospectus is part of a registration statement that we filed with the Securities and Exchange Commission (“SEC”) using a shelf registration statement. Under the shelf registration process, from time to time, we may offer and sell debt securities in one or more offerings. The accompanying prospectus contains a description of our debt securities and gives more general information, some of which may not apply to the notes.

This prospectus supplement, or the information incorporated by reference in this prospectus supplement, may add, update or change information in the accompanying prospectus. If information in this prospectus supplement, or the information incorporated by reference from a report or other document filed with the SEC after the date of the accompanying prospectus, is inconsistent with the accompanying prospectus, this prospectus supplement, or such information incorporated by reference, will supersede the information in the accompanying prospectus.

You should also read and consider the information in the documents to which we have referred you in “Where You Can Find More Information” on page S-iv of this prospectus supplement, “Information Incorporated by Reference” on page S-iv of this prospectus supplement, and “Where You Can Find More Information about Honeywell” on page 20 of the accompanying prospectus.

We have not, and the underwriters have not, authorized anyone to provide any information other than that contained in or incorporated by reference in this prospectus supplement, the accompanying prospectus, or any related free writing prospectus prepared by or on behalf of us. Neither we nor the underwriters take responsibility for, or can provide assurance as to the reliability of, any other information that others may give you. We are not, and the underwriters are not, making an offer to sell, or soliciting an offer to buy, the notes in any jurisdiction where the offer or sale is not permitted. The information in this prospectus supplement, the accompanying prospectus and any related free writing prospectus may only be accurate as of the date of such document or the information incorporated by reference herein or therein. Our business, financial condition, results of operations and/or prospects may have changed since those dates.

Absence of a Public Market There is no public trading market for the 20  fixed rate notes, the 20  fixed rate notes and the 20  fixed rate notes, and there is no intention to apply for listing of the notes of any series on any national securities exchange or for quotation of the notes of any series on any automated dealer quotations system.

Risk Factors For a discussion of factors you should carefully consider before deciding to purchase the notes, see “Risk Factors” beginning on page S-4 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 our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2024 and June 30, 2024 filed with the SEC and incorporated by reference into this prospectus supplement.

S-3

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 and our most recent Quarterly Reports on Form 10-Q 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.

An active trading market for the notes may not develop.

The reopened 20  fixed rate notes offered hereby will be a further issuance of, and will form a single series with, the original 20  fixed rate notes. Any market that has developed in the original 20  fixed rate notes may

S-4

not be maintained. There is no existing market for the 20  fixed rate notes, the 20  fixed rate notes and the 20  fixed rate notes and we do not intend to apply for listing of the notes of any series on any securities exchange or any automated quotation system. Accordingly, there can be no assurance that a trading market for the 20  fixed rate notes, the 20  fixed rate notes and the 20  fixed rate notes will ever develop or will be maintained. Further, there can be no assurance as to the liquidity of any market that may develop for the 20  fixed rate notes, the 20  fixed rate notes and the 20  fixed rate notes, your ability to sell your notes or the price at which you will be able to sell your notes. 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.

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

S-5

USE OF PROCEEDS

We estimate that the net proceeds to us from this offering will be approximately $   , after deducting the underwriting discounts and estimated offering expenses payable by us and excluding accrued interest on the reopened 20 fixed rate notes.

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 (including announced proposed acquisitions) or business expansion. Pending application for specific purposes, the net proceeds from this offering may be invested in marketable securities.

S-6

The reopened 20 fixed rate notes offered by this prospectus supplement have the same terms as the original 20 fixed rate notes, other than the issue date and the issue price. The reopened 20 fixed rate notes form a part of the same series as the original 20 fixed rate notes and will be issued under the Indenture as described below. The reopened 20 fixed rate notes are expected to have the same ISIN, Common Code and CUSIP number as, and upon closing are expected to be fully fungible (including for U.S. federal income tax purposes) and trade interchangeably with, other outstanding notes in the series. Upon completion of this offering, the aggregate principal amount of outstanding notes by this series will be $   .

The notes will be issued only in registered, book-entry form without interest coupons in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. Each series of notes will be represented by one or more global notes deposited with DTC, or its nominee, and registered in book-entry form in the name of Cede & Co., DTC’s nominee.

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.

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.

Optional Redemption

Prior to    (the date that is    prior to the maturity date of the 20  fixed rate notes) (the “20  Par Call Date”), with respect to the 20 fixed rate notes, prior to    (the date that is    prior to the maturity date of the 20  fixed rate notes) (the “20  Par Call Date”), with respect to the 20  fixed rate notes, prior to    (the date that is    prior to the maturity date of the 20 fixed rate notes) (the “20  Par Call Date”), and with respect to the reopened 20  fixed rate notes, prior to    (the date that is    prior to the maturity date of the reopened 20 fixed rate notes) (the “20 Par Call Date” and, each of the 20  Par Call Date, the 20 Par Call Date, the 20 Par Call Date and the 20  Par Call Date, a “Par Call Date”), we may redeem the notes at our option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

(1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming that such notes matured on their applicable Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the applicable Treasury Rate plus    basis points with respect to the 20  fixed rate notes, plus     basis points with respect to the 20  fixed rate notes, plus basis points with respect to the 20  fixed rate notes and    plus     basis points with respect to the reopened 20 fixed rate notes less (b) interest accrued to the date of redemption, and

(2) 100% of the principal amount of the notes to be redeemed,

plus, in either case, accrued and unpaid interest thereon to the redemption date.

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

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 other transaction or event. In addition, if such redemption is subject to satisfaction of one or more conditions

S-8

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.

The notes called for redemption become due on the date fixed for redemption. Notices of redemption will be mailed by first-class mail or sent by electronic transmission at least 10 days but not more than 60 days before the redemption date to each holder of the applicable series of notes to be redeemed at its registered address. The notice of redemption for the notes will state, among other things, the amount and CUSIP number of the note to be redeemed. Unless we default in payment of the redemption price, on and after the date of redemption, interest will cease to accrue on any notes that are redeemed. If less than all the notes are redeemed at any time, the trustee will select notes by lot or on a pro rata basis or by any other method the trustee deems fair and appropriate in accordance with the applicable procedures of DTC.

“Business Day” means each Monday, Tuesday, Wednesday, Thursday and Friday that is not a day on which banking institutions in the place of payment are authorized or obligated by law to close.

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

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

If on the third business day preceding the redemption date H.15 TCM is no longer published, we shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to the applicable Par Call Date. If there is no United States Treasury security maturing on such Par Call Date, but there are two or more United States Treasury securities with a maturity date equally distant from such Par Call Date, one with a maturity date preceding such Par Call Date and one with a maturity date following such Par Call Date, we shall select the United States

S-9

Treasury security with a maturity date preceding such Par Call Date. If there are two or more United States Treasury securities maturing on such Par Call Date for such series of notes or two or more United States Treasury securities meeting the criteria of the preceding sentence, we shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

Our actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.

No notes of a principal amount of $2,000 or less will be redeemed in part. If any note is to be redeemed in part only, the notice of redemption that relates to the note will state the portion of the principal amount of the note to be redeemed. A new note of any series in a principal amount equal to the unredeemed portion of the note will be issued in the name of the holder of the note upon surrender for cancellation of the original note. For so long as the notes of a series are held by DTC (or another depositary), the redemption of the notes of such series shall be done in accordance with the policies and procedures of the depositary.

Except as set forth above, the notes will not be redeemable by us prior to maturity and will not be entitled to the benefit of any sinking fund.

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 CUSIP number as the notes of their 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.

Regarding the Trustee

Deutsche Bank Trust Company Americas will be the trustee 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 an underwriter in this offering and a participant in our $1.5 billion 364-Day Credit Agreement, maturing in March 2025 (unless converted to a term loan), our $1.5 billion Second 364-Day Credit Agreement, maturing in July 2025 (unless converted to a term loan) and our $4.0 billion Amended and Restated Five Year Credit Agreement, maturing in March 2029.

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-10

UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following is a summary of the material United States (“U.S.”) federal income tax considerations that may be relevant to a holder of a note. This summary is based on provisions of the Internal Revenue Code of 1986, as amended (the “Code”), applicable U.S. Department of the Treasury regulations, laws, rulings and decisions (“U.S. Treasury Regulations”) now in effect, all of which are subject to change, possibly with retroactive effect. This summary deals only with beneficial owners of notes that will hold notes as capital assets and acquired notes, in the case of the 20 fixed rate notes, the 20 fixed rate notes and the 20 fixed rate notes, upon original issuance at their original 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), and in the case of the reopened 20 fixed rate notes, in this offering at the offering price listed on the first page of this prospectus supplement. This summary does not address particular tax considerations that may be applicable to investors that are subject to special tax rules, such as banks, tax-exempt entities, insurance companies, regulated investment companies, dealers in securities or currencies, traders in securities electing to mark to market, persons that will hold notes as a position in a “straddle” or conversion transaction, or as part of a “synthetic security” or other integrated financial transaction, entities taxed as partnerships or the partners therein, U.S. expatriates, nonresident alien individuals present in the United States for more than 182 days in a taxable year, or U.S. persons that have a “functional currency” other than the U.S. dollar.

This summary addresses only U.S. federal income tax consequences, and does not address consequences arising under state, local, foreign tax laws, any alternative minimum tax or the Medicare tax on net investment income or under special timing rules prescribed under section 451(b) of the Code. Investors should consult their own tax advisors in determining the tax consequences to them of holding notes under such tax laws, as well as the application to their particular situation of the U.S. federal income tax considerations discussed below.

As used herein, a “U.S. holder” is a beneficial owner of a note that is a citizen or resident of the United States or a U.S. domestic corporation or that otherwise will be subject to U.S. federal income taxation on a net income basis in respect of the note. A “Non-U.S. holder” is a beneficial owner of a note that is an individual, corporation, estate or trust and is not a U.S. holder.

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.

U.S. Holders

Qualified Reopening. For U.S. federal income tax purposes, the reopened 20 fixed rate notes offered hereby are expected to be treated as issued in a “qualified reopening” of the original 20 fixed rate notes which were issued without original issue discount. Debt instruments issued in such a qualified reopening are deemed to be part of the same issue as the original debt instruments. Under the treatment described in this paragraph, the reopened 20 fixed rate notes will have the same issue date, the same issue price and the same adjusted issue price as the original 20 fixed rate notes for U.S. federal income tax purposes. This discussion assumes that the reopened 20 fixed rate notes offered hereby are issued in a qualified reopening.

Pre-Reopening Accrued Interest. The initial offering price for the reopened 20 fixed rate notes will include amounts attributable to interest accrued from March 1, 2024, which we call “pre-reopening accrued interest.” Pre-reopening accrued interest will be included in the accrued interest to be paid on the reopened 20 fixed rate notes on the first interest payment date after the issuance of the reopened 20 fixed rate notes. In accordance with applicable U.S. Treasury regulations, for U.S. federal income tax purposes, we will treat the reopened 20 fixed rate notes as having been issued for a price that does not include any pre-reopening accrued interest. We intend to treat the portion of the first stated interest payment equal to the pre-reopening accrued interest as a nontaxable return of such pre-reopening accrued interest and, accordingly, it generally will not be includable in income. Pre-reopening accrued interest so treated and not included in income should not form part of any amortizable bond premium, as discussed below under “Premium.” U.S. holders should consult their tax advisers regarding the tax treatment of pre-reopening accrued interest.

S-11

Payments of Interest. Subject, in the case of the reopened 20 fixed rate notes, to the discussion above regarding pre-reopening accrued interest, and the discussion below regarding premium, payments of stated interest will be taxable to a U.S. holder as ordinary interest income at the time it accrues or is actually or constructively received, in accordance with the holder’s method of accounting for U.S. federal income tax purposes. It is expected, and this discussion assumes, that the newly issued notes will be issued without original issue discount (“OID”). In general, however, if such notes are issued with OID at or above a de minimis threshold, a U.S. holder of such notes 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.

Premium. A U.S. holder that purchases the reopened 20 fixed rate notes offered hereby at a cost (excluding any amount attributable to pre-reopening accrued interest) greater than the principal amount of those notes will be considered to have purchased those notes at a premium, and generally may elect to amortize the premium (as an offset to interest income), using a constant yield method, over the remaining term of those notes. However, because we may redeem the 20 fixed rate notes prior to maturity at a premium, special rules apply that may reduce, eliminate or defer the amount of premium that a U.S. holder may amortize with respect to those notes. If a U.S. holder makes the election to amortize premium, it generally will apply to all taxable debt instruments that the U.S. holder holds during the taxable year for which the election is made, as well as any taxable debt instruments that such U.S. holder subsequently acquire. In addition, a U.S. holder may not revoke the election without the consent of the Internal Revenue Service (the “IRS”). U.S. holders that elect to amortize the premium will be required to reduce their tax basis in the 20 fixed rate notes by the amount of the premium amortized during their holding period. For U.S. holders that do not elect to amortize premium, the amount of premium will be included in their tax basis in the 20 fixed rate notes. Therefore, if a U.S. holder does not elect to amortize premium and holds the 20 fixed rate notes to maturity, such U.S. holder generally will be required to treat the premium as capital loss when those notes mature.

Sale, Exchange and Retirement of Notes. Upon the sale, exchange or retirement of a note, a U.S. holder generally will recognize gain or loss equal to the difference between the amount realized on the sale, exchange or retirement (less any accrued interest, which will be taxable as such) and the U.S. holder’s adjusted tax basis in such note.

A U.S. holder’s adjusted tax basis in a note should generally equal the cost of the note to such holder (in the case of the reopened 20 fixed rate notes, excluding any amount attributable to pre-reopening accrued interest and reduced by any amortizable bond premium previously amortized). Gain or loss recognized by a U.S. holder generally will be long-term capital gain or loss if the U.S. holder has held the note for more than one year at the time of disposition. Long-term capital gains recognized by a non-corporate U.S. holder generally are subject to tax at a lower rate than short-term capital gains or ordinary income. The deduction of capital losses is subject to limitations.

Non-U.S. Holders

Payments of Interest. Subject to the discussions below under “FATCA” and “Information Reporting and Backup Withholding,” 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;

S-12

and (iii) the Non-U.S. holder is not a controlled foreign corporation that is related to us actually or constructively through stock ownership. Non-U.S. holders should note that, although we intend to treat a portion of the first interest payment on the reopened 20 fixed rate notes as a non-taxable return of capital as described above under “U.S. Holders—Pre-Reopening Accrued Interest,” a payor may withhold on the full amount of the first interest payment on the reopened 20 fixed rate notes if the Non-U.S. holder does not establish an exemption from U.S. federal withholding tax as described above.

Sale, Exchange and Retirement of Notes. Subject to the discussion below under “Information Reporting and Backup Withholding,” a Non-U.S. holder generally will not be subject to U.S. federal income tax on gain recognized on a sale, exchange or retirement of any note.

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 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 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.

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.

S-13

UNDERWRITING

We are offering the notes described in this prospectus supplement through the underwriters named below, for whom Citigroup Global Markets Inc., Deutsche Bank Securities Inc., Mizuho Securities USA LLC and SMBC Nikko Securities America, Inc. 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		Principal Amount of 20  Fixed Rate Notes		Principal Amount of reopened 20  Fixed Rate Notes
Citigroup Global Markets Inc.	$		$		$		$
Deutsche Bank Securities Inc.
Mizuho Securities USA LLC
SMBC Nikko Securities America, Inc.
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, less concessions not in excess of  % of the principal amount of the 20  fixed rate notes, 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 reopened 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, not in excess of  % of the principal amount of the 20  fixed rate notes, 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 reopened 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 with no established trading market. The notes of all series will not be listed on any securities exchange or on any automated dealer quotation system. The

S-14

representatives may make a market in each series of the notes after completion of the offering, but will not be obligated to do so and may discontinue any market making activities at any time without notice. No assurance can be given as to the liquidity of the trading market for any series of the notes or that an active public market for the notes of any series will develop. If an active public market for the notes of any series does not develop, the market price and liquidity of the notes of any series may be adversely affected.

Price Stabilization and Penalty Bids

In connection with this offering, the underwriters (or any person acting on behalf of the underwriters) 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 persons acting on behalf of the stabilizing manager) in accordance with all applicable laws and rules. There is no assurance that the stabilizing manager(s) (or persons acting on behalf of a stabilizing manager) will undertake any stabilization action.

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.

T+3 Settlement

We expect that delivery of the notes will be made to investors on or about the third business day following the date of this prospectus supplement (such settlement being referred to as “T+3”). Under Rule 15c6-1 under the

S-15

Exchange Act, trades in the secondary market are generally required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes more than one business day prior to their date of delivery will be required, by virtue of the fact that the notes initially settle in T+3, 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 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.

In this section, the terms “we,” “our,” “us” and “Honeywell” refer solely to Honeywell International Inc. and not its subsidiaries.

For a complete description of any series of debt securities, you should read both this prospectus and the prospectus supplement relating to that series of debt securities.

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.

We are not obligated to issue all debt securities of one series at the same time and, unless otherwise provided in the prospectus supplement, we may reopen a series, without the consent of the holders of the debt securities of that series, for the issuance of additional debt securities of that series. Additional debt securities of a particular series will have the same terms and conditions as outstanding debt securities of such series, except for the 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.
