Philip Morris International (PM) 424B2Prospectus for primary offering

The following description of the particular terms of the notes supplements the description of the general terms and provisions of the debt securities set forth under “Description of Debt Securities” beginning on page 5 in the attached prospectus. The attached prospectus contains a detailed summary of additional provisions of the notes and of the indenture, dated as of April 25, 2008, between Philip Morris International Inc. and HSBC Bank USA, National Association, as trustee, under which the notes will be issued. The following description supersedes the description of the debt securities in the attached prospectus, to the extent of any inconsistency. Terms used in this prospectus supplement that are otherwise not defined will have the meanings given to them in the attached prospectus.

The 2027 Notes are a series of debt securities described in the attached prospectus, which will be senior debt securities, will initially be issued in the aggregate principal amount of $750,000,000 and will mature on November 1, 2027.

The 2027 Notes will bear interest at the rate of 4.375% per annum from November 1, 2024, payable semiannually in arrears on May 1 and November 1 of each year, commencing May 1, 2025, to the persons in whose names the 2027 Notes are registered at the close of business on the preceding April 15 or October 15, each a record date, as the case may be.

The 2029 Notes are a series of debt securities described in the attached prospectus, which will be senior debt securities, will initially be issued in the aggregate principal amount of $750,000,000 and will mature on November 1, 2029.

The 2029 Notes will bear interest at the rate of 4.625% per annum from November 1, 2024, payable semiannually in arrears on May 1 and November 1 of each year, commencing May 1, 2025, to the persons in whose names the 2029 Notes are registered at the close of business on the preceding April 15 or October 15, each a record date, as the case may be.

The 2031 Notes are a series of debt securities described in the attached prospectus, which will be senior debt securities, will initially be issued in the aggregate principal amount of $750,000,000 and will mature on November 1, 2031.

The 2031 Notes will bear interest at the rate of 4.750% per annum from November 1, 2024, payable semiannually in arrears on May 1 and November 1 of each year, commencing May 1, 2025, to the persons in whose names the 2031 Notes are registered at the close of business on the preceding April 15 or October 15, each a record date, as the case may be.

The 2034 Notes are a series of debt securities described in the attached prospectus, which will be senior debt securities, will initially be issued in the aggregate principal amount of $750,000,000 and will mature on November 1, 2034.

The 2034 Notes will bear interest at the rate of 4.900% per annum from November 1, 2024, payable semiannually in arrears on May 1 and November 1 of each year, commencing May 1, 2025, to the persons in whose names the 2034 Notes are registered at the close of business on the preceding April 15 or October 15, each a record date, as the case may be.

On or after the 2034 Par Call Date, we may, at our option, redeem the 2034 Notes, in whole at any time or in part from time to time (equal to $2,000 or an integral multiple of $1,000 in excess thereof) at a redemption price equal to 100% of the principal amount of the 2034 Notes to be redeemed, plus accrued and unpaid interest, if any, thereon to, but excluding, the redemption date.

“Comparable Treasury Issue” means the U.S. Treasury security or securities selected by an Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term of the notes to be redeemed, as applicable (assuming for this purpose that the 2027 Notes matured on November 1, 2027, the 2029 Notes matured on the 2029 Par Call Date, the 2031 Notes matured on the 2031 Par Call Date and the 2034 Notes matured on the 2034 Par Call Date) that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of a comparable maturity to the remaining term of such notes.

“Comparable Treasury Price” means, with respect to any redemption date (1) the average of the Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference Treasury Dealer Quotation or (2) if the Independent Investment Banker obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.

“Reference Treasury Dealer” means each of BBVA Securities Inc., BofA Securities, Inc., Deutsche Bank Securities Inc., Goldman Sachs & Co. LLC and Wells Fargo Securities, LLC or their affiliates, which are primary United States government securities dealers and one other leading primary U.S. government securities dealer in New York City reasonably designated by us; provided, however, that if any of the foregoing shall cease to be a primary U.S. government securities dealer in New York City (a “Primary Treasury Dealer”), we will substitute therefor another Primary Treasury Dealer.

“Reference Treasury Dealer Quotation” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Banker by such Reference Treasury Dealer at 2:00 pm New York time on the third business day preceding such redemption date.

“Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the semiannual equivalent yield to maturity or interpolated maturity (on a day count basis) of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (such price expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date.

We will, or will cause the trustee or paying agent on our behalf to, mail notice of a redemption to holders of the applicable notes to be redeemed by first-class mail (or otherwise transmit in accordance with applicable procedures of DTC) at least 15 and not more than 45 days prior to the date fixed for redemption. Unless we default in the payment of the redemption price, on and after the redemption date, interest will cease to accrue on the applicable notes or any portion thereof called for redemption. On or before the applicable redemption date, we will deposit with the trustee, funds sufficient to pay the redemption price of, and (unless the redemption date shall be an interest payment date) accrued and unpaid interest on, such notes to be redeemed on that redemption date. If fewer than all of the notes of any series of notes are to be redeemed, the notes to be redeemed, as applicable, shall be selected, in the case of notes in definitive form, by lot. If any note in definitive form is to be redeemed in part only, the notice of redemption that relates to such note will state the portion of the principal amount of the note to be redeemed. A new note in definitive form in a

We may at any time, and from time to time, purchase notes of any series at any price or prices in the open market or otherwise.

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

The notes will be offered and sold in principal amounts of $2,000 and integral multiples of $1,000 in excess thereof. We will issue the notes of each series in the form of one or more permanent global notes in fully registered, book-entry form, which we refer to as the “global notes.” Each such global note will be deposited with, or on behalf of, DTC or any successor thereto, as depositary (“Depositary”), and registered in the name of Cede & Co. (as nominee of DTC). Unless and until it is exchanged in whole or in part for notes in definitive form, no global note may be transferred except as a whole by the Depositary to a nominee of such Depositary. Investors may elect to hold interests in the global notes through either the Depositary (in the United States) or through Clearstream or Euroclear, if they are participants in such systems, or indirectly through organizations that are participants in such systems. Clearstream and Euroclear will hold interests on behalf of their participants through customers’ securities accounts in Clearstream’s and Euroclear’s names on the books of their respective depositaries, which in turn will hold such interests in customers’ securities accounts in the depositaries’ names on the books of DTC.

DTC advises that it is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered pursuant to the provision of Section 17A of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). DTC holds securities that its participants (“DTC Participants”) deposit with DTC. DTC also facilitates settlement of securities transactions among the DTC Participants, such as transfers and pledges in deposited securities through electronic computerized book-entry changes in accounts of the DTC Participants, thereby eliminating the need for physical movement of securities certificates.

Direct DTC Participants (“DTC Direct Participants”) include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. Access to DTC’s book-entry system is also available to others, such as banks, securities brokers and dealers that clear through or maintain a custodial relationship with a DTC Direct Participant, either directly or indirectly (we refer to the latter as “DTC Indirect Participants”).

Purchases of the notes under DTC’s book-entry system must be made by or through DTC Direct Participants, which will receive a credit for the notes on DTC’s records. The ownership interest of each actual purchaser of the notes, which we refer to as the “beneficial owner,” is in turn to be recorded on the DTC Participants’ records. Beneficial owners will not receive written confirmation from DTC of their purchase, but beneficial owners are expected to receive written confirmations providing details of the transactions, as well as periodic statements of their holdings from the DTC Direct or DTC Indirect Participant through which the beneficial owner entered into the transaction. Transfers of ownership interests in the global notes will be effected only through entries made on the books of DTC Participants acting on behalf of beneficial owners. Beneficial owners will not receive certificates representing their ownership interests in the global notes, except in the event that use of the book-entry system for the notes is discontinued.

Upon the deposit of a registered global note, DTC will credit, on its book-entry registration and transfer system, the DTC Participants’ accounts with the respective principal or face amounts of the relevant series

To facilitate subsequent transfers, all global notes deposited by DTC Direct Participants with DTC are registered in the name of DTC’s partnership nominee, Cede & Co. or such other name as may be requested by an authorized representative of DTC. The deposit of the global notes with DTC and their registration in the name of Cede & Co. or such other nominee effect no change in beneficial ownership. DTC has no knowledge of the actual beneficial owners of the notes; DTC’s records reflect only the identity of the DTC Direct Participants to whose accounts such notes are credited, which may or may not be the beneficial owners. The DTC Participants will remain responsible for keeping account of their holdings on behalf of their customers.

So long as DTC, or its nominee, is the registered owner of a registered global note, DTC or its nominee, as the case may be, will be considered the sole owner or holder of the relevant series of notes represented by the global note for all purposes under the indenture. Except as described below, owners of beneficial interests in a global note will not be entitled to have the book-entry notes represented by the notes registered in their names, will not receive or be entitled to receive physical delivery of notes in definitive form and will not be considered the owners or holders of the notes under the indenture. Accordingly, each person owning a beneficial interest in a global note must rely on the procedures of DTC for that global note and, if that person is not a DTC Participant, on the procedures of the DTC Participant through which the person owns its interest, to exercise any rights of a holder under the indenture. The laws of some jurisdictions may require that some purchasers of notes take physical delivery of these notes in definitive form. Consequently, the ability to transfer beneficial interests in a global note to such persons may be limited. In addition, because DTC can act only on behalf of DTC Direct Participants, which in turn act on behalf of DTC Indirect Participants, the ability of a person having a beneficial interest in a global note to pledge or transfer such interests to persons or entities that do not participate in DTC’s system, or otherwise to take actions in respect of such interest, may be affected by the lack of a physical certificate evidencing such interest.

PMI will make payments due on the notes to Cede & Co. in immediately available funds. DTC’s practice upon receipt of any payment of principal, premium, interest or other distribution of underlying securities or other property to holders on that global note, is to immediately credit the DTC Participants’ accounts in amounts proportionate to their respective beneficial interests in that global note as shown on the records of the Depositary. Payments by DTC Participants to owners of beneficial interests in a global note held through DTC Participants will be governed by standing customer instructions and customary practices, as is now the case with the securities held for the accounts of customers registered in “street name,” and will be the responsibility of those DTC Participants. Payment to Cede & Co. is the responsibility of PMI. Disbursement of such payments to direct participants is the responsibility of Cede & Co. Disbursement of such payments to the beneficial owners is the responsibility of DTC Direct and DTC Indirect Participants. None of PMI, the trustee or any other agent of ours or any agent of the trustee will have any responsibility or liability for any aspect of the records relating to payments made on account of beneficial ownership interests in the global notes or for maintaining, supervising or reviewing any records relating to those beneficial ownership interests.

Redemption notices shall be sent to DTC. If less than all of the notes within a series are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each DTC Direct Participant in such series to be redeemed. DTC may discontinue providing its service as securities depositary with respect to the notes at any time by giving reasonable notice to us or the trustee.

Clearstream advises that it is incorporated under the laws of Luxembourg as a professional depositary. Clearstream holds securities for its participating organizations (“Clearstream Participants”) and facilitates the clearance and settlement of securities transactions between Clearstream Participants through electronic book-entry changes in accounts of Clearstream Participants, thereby eliminating the need for physical movement of certificates. Clearstream, Luxembourg provides to Clearstream Participants, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream interfaces with domestic markets in several countries.

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

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

Euroclear is operated by Euroclear Bank, SA/NV (the “Euroclear Operator”). All operations are conducted by the Euroclear Operator, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator. Euroclear Participants include banks (including central banks), securities brokers and dealers and other professional financial intermediaries and may include the underwriters. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear Participant, either directly or indirectly.

The Terms and Conditions Governing Use of Euroclear and the related Operating Procedures of the Euroclear System (the “Euroclear Terms and Conditions”) and applicable Belgian law govern securities clearance accounts and cash accounts with the Euroclear Operator. Specifically, these terms and conditions govern transfers of securities and cash within Euroclear, withdrawals of securities and cash from Euroclear, and receipt of payments with respect to securities in Euroclear. All securities in Euroclear are held on a fungible basis without attribution of specific certificates to specific securities clearance accounts. The Euroclear Operator acts under the terms and conditions only on behalf of Euroclear Participants and has no record of or relationship with persons holding securities through Euroclear Participants.

any tax, assessment or other governmental charge that is imposed or withheld solely by reason of the beneficial owner (or a fiduciary, settlor, beneficiary or person holding a power over such beneficial owner, if the beneficial owner is an estate or trust, or a member or shareholder of the beneficial owner, if the beneficial owner is a partnership or corporation) being or having been with respect to the United States a personal holding company, a controlled foreign corporation, a passive foreign investment company or a foreign private foundation or other foreign tax-exempt organization, or being a corporation that accumulates earnings to avoid United States federal income tax;

any tax, assessment or other governmental charge imposed on a beneficial owner that actually or constructively owns 10% or more of the total combined voting power of all of our classes of stock that are entitled to vote within the meaning of Section 871(h)(3) of the Internal Revenue Code of 1986, as amended (the “Code”);

any tax, assessment or other governmental charge that is payable by any method other than withholding or deduction by us or any paying agent from payments in respect of such note;

any gift, estate, inheritance, sales, transfer, personal property or excise tax or any similar tax, assessment or other governmental charge;

any tax, assessment or other governmental charge required to be withheld by any paying agent from any payment in respect of any note if such payment can be made without such withholding by at least one other paying agent;

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

any tax, assessment or other governmental charge imposed as a result of the failure of the beneficial owner to comply with applicable certification, information, documentation or other reporting requirements concerning the nationality, residence, identity or connection with the United States of the holder or beneficial owner of a note, if such compliance is required by statute or regulation of the United States as a precondition to relief or exemption from such tax, assessment or other governmental charge;

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

any tax, assessment or other governmental charge imposed pursuant to the provisions of Sections 1471 through 1474 of the Code; or

The following summary describes generally the material United States federal income and, in the case of non-United States Holders (as defined below), estate tax considerations with respect to your acquisition, ownership and disposition of a note if you are a beneficial owner of such note. Unless otherwise indicated, this summary addresses only notes purchased at original issue for their original offering price and held by beneficial owners as capital assets, and does not address all of the United States federal income and estate tax considerations that may be relevant to you in light of your particular circumstances or if you are subject to special treatment under United States federal income tax laws (for example, if you are an insurance company, tax-exempt organization, financial institution, broker or dealer in securities or currencies, trader in securities that elects to use the mark-to-market method of accounting for your securities holdings, person subject to any alternative minimum tax, United States expatriate, United States person with a functional currency other than the U.S. dollar, person that holds notes as part of an integrated investment (including a “straddle”), “controlled foreign corporation,” “passive foreign investment company,” person required to accelerate the recognition of gross income with respect to the notes as a result of such income being recognized on an applicable financial statement, or corporation that accumulates earnings to avoid United States federal income tax). If a partnership holds notes, the tax treatment of a partner generally will depend upon the status of the partner and the activities of the partnership. A partner of a partnership holding our notes should consult its own tax advisor regarding the tax consequences of the acquisition, ownership and disposition of our notes, as this summary does not address special tax considerations that may be relevant to such a partner. This summary does not discuss any aspect of state, local or non-United States taxation, or any United States federal tax considerations other than income and estate taxation.

This summary is based on current provisions of the Code, Treasury regulations, judicial opinions, published positions of the United States Internal Revenue Service (“IRS”) and all other applicable authorities, all of which are subject to change, possibly with retroactive effect. This summary is not intended as tax advice.

This discussion applies to you if you are a “United States Holder.” For this purpose, a “United States Holder” is a beneficial owner of a note that is:

a citizen or individual resident of the United States;

a corporation, or other entity treated as a corporation for United States federal income tax purposes, created or organized in, or under the laws of, the United States or any political subdivision of the United States;

an estate, the income of which is subject to United States federal income taxation regardless of its source;

Payments of interest on a note generally will be taxable to you as ordinary interest income at the time the interest accrues or is received, in accordance with your method of accounting for tax purposes.

Upon the sale, exchange, redemption or other taxable disposition of a note, you will recognize taxable gain or loss equal to the difference between (i) the amount you realize on the sale, exchange, redemption or

Unless you are an exempt recipient, backup withholding and certain information reporting requirements may apply to payments we make to you of principal of, and interest or premium (if any) on, and proceeds of the sale or exchange before maturity of, a note. Backup withholding and information reporting will not apply to payments that we make on the notes to exempt recipients that establish their status as such, regardless of whether such entities are the beneficial owners of such notes or hold such notes as a custodian, nominee or agent of the beneficial owner. However, with respect to payments made to a custodian, nominee or agent of the beneficial owner, backup withholding and information reporting may apply to payments made by such custodian, nominee or other agent to you unless you are an exempt recipient and establish your status as such.

If you are not an exempt recipient (for example, if you are an individual), backup withholding will not be applicable to payments made to you if you (i) have supplied an accurate Taxpayer Identification Number (usually on an IRS Form W-9), (ii) have not been notified by the IRS that you have failed to properly report payments of interest and dividends and (iii) have certified under penalties of perjury that you have received no such notification and have supplied an accurate Taxpayer Identification Number. However, information reporting will be required in such a case.

Any amounts withheld from a payment to you by operation of the backup withholding rules will be refunded or allowed as a credit against your United States federal income tax liability, provided that any required information is furnished to the IRS in a timely manner.

A tax of 3.8% is imposed on the amount of “net investment income” ​(or undistributed “net investment income,” in the case of an estate or trust) received by taxpayers with adjusted gross income above certain threshold amounts. “Net investment income” as defined for United States federal Medicare contribution purposes generally includes interest payments and gain recognized from the sale or other disposition of the notes. Tax exempt trusts, which are not subject to income taxes generally, and foreign individuals will not be subject to this tax. You should consult your own tax advisors regarding the effect, if any, of this tax on your investment in the notes.

This discussion applies to you if you are a “non-United States Holder.” A “non-United States Holder” is a beneficial owner of a note that is neither a United States Holder nor a partnership (or other entity treated as a partnership for United States federal income tax purposes).

Payments of interest that we make to you will be subject to United States withholding tax at a rate of 30% of the gross amount, unless you are eligible for one of the exceptions described below.

Subject to the discussion of backup withholding and FATCA below, no withholding of United States federal income tax will be required with respect to payments we make to you of interest provided that:

you do not actually or constructively own 10% or more of the total combined voting power of all classes of our stock entitled to vote within the meaning of Section 871(h)(3) of the Code;

To satisfy these certification requirements, you generally will be required to provide, prior to a payment of interest, a statement that:

This statement generally may be made on an IRS Form W-8BEN or W-8BEN-E or a substantially similar substitute form and you must inform the recipient of any change in the information on the statement within 30 days of such change. Special certification rules apply to non-United States Holders that are pass-through entities rather than corporations or individuals.

If you are engaged in a United States trade or business and interest received by you on a note is effectively connected with your conduct of such trade or business (and, under certain income tax treaties, is attributable to a United States permanent establishment you maintain), you will be exempt from the withholding of United States federal income tax described above, so long as you have provided an IRS Form W-8ECI or substantially similar substitute form stating that interest on the note is effectively connected with your conduct of a trade or business in the United States. In such a case, you will be subject to tax on interest you receive on a net income basis in the same manner as if you were a United States Holder. If you are a corporation, effectively connected income may also be subject to a branch profits tax at a rate of 30% (or such lower rate as may be specified by an applicable income tax treaty).

If you are not eligible for relief under one of the exceptions described above, the amount of any interest that we pay to you that is subject to withholding may be reduced if we qualify as an “80/20 company” for United States federal income tax purposes. A U.S. corporation that was an 80/20 company on August 10, 2010 generally continues to be an 80/20 company if at least 80% of its gross income during an applicable testing period is, directly or through subsidiaries, “active foreign business income,” and it does not add a substantial line of business to its operations. The 80% test for active foreign business income is computed annually. Although we believe that we currently are an 80/20 company, our operations and business plans may change in subsequent taxable years. Therefore, no assurance can be given regarding our classification as an 80/20 company for United States federal income tax purposes in the future.

The amount of interest we pay to you on notes will be reported to you and to the IRS annually on an IRS Form 1042-S even if you are exempt from the 30% withholding tax described above. Copies of the information returns reporting those payments and the amounts withheld may also be made available to the tax authorities in the country where you are resident under provisions of an applicable income tax treaty or agreement.

In addition, backup withholding and certain other information reporting requirements apply to payments of interest and certain reportable payments, unless an exemption applies. Backup withholding and such other information reporting requirements will not apply to payments we make to you if you have provided under penalties of perjury the required certification of your non-United States person status as discussed above under “Payments of Interest” ​(and the applicable withholding agent does not have actual knowledge or reason to know that you are a United States Holder) or if you are an exempt recipient.

If you sell or redeem a note through a United States broker or the United States office of a foreign broker, the proceeds from such sale or redemption will be subject to information reporting and backup withholding unless you provide a withholding certificate or other appropriate documentary evidence establishing that you are not a United States Holder to the broker and such broker does not have actual knowledge or reason to know that you are a United States Holder, or you are an exempt recipient eligible for an exemption from information reporting and backup withholding. If you sell or redeem a note through the foreign office of a broker who is a United States person or has certain specified connections with the United States, the proceeds from such sale or redemption will be subject to information reporting unless you provide to such broker a withholding certificate or other documentary evidence establishing that you are not a United States Holder and such broker does not have actual knowledge or reason to know that such evidence is unreliable or incorrect, or you are an exempt recipient eligible for an exemption from information reporting. In circumstances where information reporting by the foreign office of such a broker is required, backup withholding will be required only if the broker has actual knowledge that you are a United States Holder.

Any amounts withheld from a payment to you by operation of the backup withholding rules will be refunded or allowed as a credit against your United States federal income tax liability, if any, provided that you timely file a United States federal income tax return with the IRS claiming such refund or credit.

A note held by an individual who at the time of death is a non-United States Holder will not be subject to United States federal estate tax as a result of such individual’s death, provided that such individual does not actually or constructively own 10% or more of the total combined voting power of all classes of our stock entitled to vote within the meaning of Section 871(h)(3) of the Code and provided that the interest payments with respect to such note are not effectively connected with such individual’s conduct of a United States trade or business.

Sections 1471 through 1474 of the Code (commonly known as FATCA) may impose a 30% withholding tax on payments of any interest income on the notes, and gross proceeds from the disposition of the notes, to certain non-U.S. entities (whether such non-U.S. entities are beneficial owners or intermediaries), including certain foreign financial institutions and investment funds, unless such non-U.S. entity complies with certain specified information reporting and other requirements, including reporting requirements regarding its United States account holders (in the case of foreign financial institutions) or substantial United States owners (in the case of non-financial foreign entities). Under proposed regulations promulgated by the Treasury

The underwriting agreement provides that the obligations of the underwriters to purchase the notes included in this offering are subject to approval of certain legal matters by counsel and to certain other conditions. The underwriters are obligated to purchase all of the notes if they purchase any of the notes.

The underwriters also may impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discounts received by it because the stabilizing agent has repurchased notes sold by or for the account of such underwriter in stabilizing or short covering transactions.

Any of these activities may cause the prices of the notes to be higher than the prices that otherwise would exist in the open market in the absence of such transactions. These transactions may be effected in the over-the-counter market or otherwise and, if commenced, may be discontinued at any time. Neither we nor any of the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the prices of the notes. In addition, neither we nor any of the underwriters make any representation that any of the underwriters will engage in such transactions, or that such transactions, once begun, will not be discontinued without notice.

We estimate that our total expenses of this offering, excluding underwriting discounts, will be approximately $3.1 million.

Each of the representatives and certain of 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.

In addition, certain of the underwriters and their affiliates have performed certain investment banking, advisory or general financing and banking services for us and our affiliates from time to time, for which they have received customary fees and expenses. Certain of the underwriters and their affiliates may, from time to time, engage in transactions with and perform services for us and our affiliates in the ordinary course of their business. The representatives or their affiliates and certain of the underwriters or their affiliates have been or are lenders in connection with our existing credit facilities or dealers in connection with our commercial paper programs. These companies receive standard fees for their services.

In the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments, including serving as counterparties to certain derivative and hedging arrangements, 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 the issuer. 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.

Any underwriter that is not a broker-dealer registered with the SEC will only make sales of notes in the United States through one or more SEC registered broker-dealers in compliance with applicable securities laws and the rules of the Financial Industry Regulatory Authority, Inc.

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

It is expected that delivery of the notes will be made against payment therefor on or about November 1, 2024, which will be the second business day following the date of pricing of the notes (such settlement cycle being herein referred to as T+2). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes prior to the delivery date will be required, by virtue of the fact that the notes initially settle in T+2, to specify an alternate settlement arrangement at the time of any

This prospectus supplement and the attached prospectus may not be used for or in connection with an offer or solicitation by any person in any jurisdiction in which that offer or solicitation is not authorized or to any person to whom it is unlawful to make that offer or solicitation.

Each of the underwriters has severally represented and agreed that it has not offered, sold or delivered and it will not offer, sell or deliver, directly or indirectly, any of the notes, or distribute this prospectus supplement or the attached prospectus or any other offering material relating to the notes, in or from any jurisdiction except under circumstances that will result in compliance with the applicable laws and regulations thereof and that will not impose any obligations on us except as agreed to with us in advance of such offer, sale or delivery.

The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (“EEA”). For these purposes, the expression “retail investor” means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); or (ii) a customer within the meaning of Directive (EU) 2016/97 (as amended or superseded, the “Insurance Distribution Directive”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Regulation (EU) 2017/1129 (as amended, the “Prospectus Regulation”). Consequently, no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation. This prospectus supplement and the accompanying prospectus have been prepared on the basis that any offer of notes in any member state of the EEA will be made pursuant to an exemption under the Prospectus Regulation from the requirement to publish a prospectus for offers of notes. Neither this prospectus supplement nor the accompanying prospectus is a prospectus for the purposes of the Prospectus Regulation.

We are a leading international tobacco company working to deliver a smoke-free future and to evolve our portfolio for the long term to include products outside of the tobacco and nicotine sector. Our current product portfolio primarily consists of cigarettes and smoke-free products, which include heat-not-burn, vapor, and oral nicotine products. Since 2008, we have invested more than $10.5 billion to develop, scientifically substantiate and commercialize innovative smoke-free products for adults who would otherwise continue to smoke, with the goal of completely ending the sale of cigarettes. This investment includes the building of world-class scientific assessment capabilities, notably in the areas of pre-clinical systems toxicology, clinical and behavioral research, as well as post-market studies.

In 2021, we laid the foundation for our long-term growth ambitions beyond nicotine in wellness and healthcare, including the milestone acquisitions of Vectura Group plc and Fertin Pharma A/S, which provide essential capabilities for future product development. Now, through our Vectura Fertin Pharma subsidiary, with a strong foundation and significant expertise in life sciences, we aim to expand into wellness and healthcare areas.

As of December 31, 2022, we managed our business in six geographical segments, a Swedish Match segment and a Wellness and Healthcare segment:

European Union;

To further support the growth of our smoke-free business, reinforce consumer centricity, and increase the speed of innovation and deployment, in January 2023, we rearranged our operations in four geographical segments, down from the current six and as follows:

Europe Region is headquartered in Lausanne, Switzerland, and covers all the European Union countries, Switzerland, the United Kingdom, and also Ukraine, Moldova and Southeast Europe;

we fail to perform, or breach, any other covenant or warranty in respect of any debt security of that series contained in the indenture or in such debt securities or in the applicable board resolution under which such series is issued and this failure or breach continues for 90 days after we receive written notice of it from the trustee or holders of 25% in aggregate principal amount of all outstanding series of the debt securities or, with respect to any such covenant or agreement which is not applicable to all series of debt securities, by the holders of at least 25% in aggregate principal amount of the affected series (in each case voting as a single class);

we or a court take certain actions relating to bankruptcy, insolvency or reorganization of our company; or

any other event of default that may be specified for the debt securities of the series or in the board resolution with respect to the debt securities of that series.

Subject to certain conditions, the holders of a majority in principal amount of the outstanding debt securities of a series may rescind a declaration of acceleration if all Events of Default, other than the failure to pay principal or interest due solely because of the declaration of acceleration, have been cured or waived. (Section 502)

liens for the sole purpose of extending, renewing or replacing in whole or in part the indebtedness secured by any lien referred to in the foregoing three bullet points or in this bullet point; provided, however, that the principal amount of indebtedness secured thereby shall not exceed the principal amount of indebtedness so secured at the time of such extension, renewal or replacement, and that such extension, renewal or replacement shall be limited to all or a part of the property which secured the lien so extended, renewed or replaced (plus improvements on such property).

Notwithstanding the foregoing, we and/or any of our Subsidiaries may create, assume or incur liens that would otherwise be subject to the restriction described above, without securing debt securities issued under the indenture equally and ratably, if the aggregate value of all outstanding indebtedness secured by the liens plus the value of Sale and Leaseback Transactions does not at the time exceed 15% of Consolidated Net Tangible Assets. (Section 1007)

A Sale and Leaseback Transaction by us or any of our Subsidiaries of any Principal Facility is prohibited, unless within 90 days of the effective date of the arrangement, an amount equal to the greater of the net proceeds of the sale of the property leased pursuant to the Sale and Leaseback Transaction or the fair value of the property at the time of entering into the Sale and Leaseback Transaction as determined by our board of directors (“value”) is applied by us to the retirement of non-subordinated indebtedness for money borrowed with more than one year stated maturity, including our debt securities, except that such sales and leasebacks are permitted to the extent that the “value” thereof plus the other secured debt referred to in the penultimate paragraph above in the subsection entitled “Restrictive Covenants — Limitations on Liens” does not at the time exceed 15% of our Consolidated Net Tangible Assets. (Section 1008)

There are no other restrictive covenants in the indenture. The indenture does not require us to maintain any financial ratios, minimum levels of net worth or liquidity or restrict the incurrence of indebtedness, the makeup of asset sales, the payment of dividends, the making of other distributions on our capital stock or the redemption or purchase of our capital stock. Moreover, the indenture does not contain any provision requiring us to repurchase or redeem any debt securities or debt warrants or modify the terms thereof or afford the holders thereof any other protection in the event of our change of control, any highly leveraged transaction or any other event involving us that may materially adversely affect our creditworthiness or the value of the debt securities or debt warrants.

We define Subsidiaries as any corporation of which at least a majority of all outstanding stock or other interests having ordinary voting power in the election of directors, managers or trustees of such corporation is at the time, directly or indirectly, owned or controlled by us or by one or more Subsidiaries or by us and one or more Subsidiaries. (Section 101)

We define Principal Facility as all real property constituting part of any manufacturing plant or distribution facility owned and operated by us or any Subsidiary, together with such manufacturing plant or distribution facility, including all attached plumbing, electrical, ventilating, heating, cooling, lighting and other utility systems, ducts and pipes, but excluding trade fixtures, business machinery, equipment, motorized vehicles, tools, supplies and materials, security systems, cameras, inventory and other personal property and materials. The term Principal Facility shall not include any particular manufacturing plant or distribution facility as of any particular date unless its net book value exceeds 0.75% of Consolidated Net Tangible Assets. (Section 1007)

We define a Sale and Leaseback Transaction as the sale or transfer of a Principal Facility with the intention of taking back a lease of the property, except a lease for a temporary period of less than three years, including renewals, with the intent that the use by us or any Subsidiary will be discontinued on or before the expiration of such period. (Section 1008)

If we accomplish covenant defeasance, the following provisions, among others, of the indenture and the debt securities would no longer apply:

our promises previously described under “Restrictive Covenants — Limitation on Liens;”

Moneys deposited with the trustee or any paying agent for the payment of principal of, or any premium and interest on, any debt securities that remain unclaimed for two years will be repaid to us at our request, unless the law requires otherwise. If this happens and you want to claim these moneys, you must look to us and not to the trustee or paying agent. (Section 409)

Without the consent of any holders of debt securities, we and the trustee may supplement the indenture, among other things, to:

pledge property to the trustee as security for the debt securities;

With the consent of the holders of not less than a majority in principal amount of all series of the debt securities that would be affected by a modification of the indenture (voting as a single class), the indenture permits us and the trustee to supplement the indenture or modify in any way the terms of the indenture or the rights of the holders of the debt securities of such series. However, without the consent of each holder of all of the debt securities affected by that modification, we and the trustee may not:

modify the maturity date of, or any installment of principal or interest on, any debt security, or reduce the principal of, or premium on, or change the stated final maturity of, any debt security;

A supplemental indenture that modifies or eliminates a provision that has been included solely for the benefit of the holders of one or more series of debt securities will not affect the rights under the indenture of holders of other series of debt securities.

As described in the first paragraph of this subsection, as well as above under “Waivers Under the Indenture” and “Events of Default” above, the indenture provides for a voting mechanism whereby all series of debt securities that may be affected (voting as a single class) will be permitted to approve certain waivers or amendments that affect all such series of debt securities. Therefore, series of debt securities in the aggregate (voting as a single class) may, in certain circumstances, approve waivers or amendments applicable to a class of debt securities that is also affected by such waiver or amendment and that did not vote in favor of such waiver or amendment.

The specific terms of any redemption of a series of debt securities will be contained in the prospectus supplement for that series. We must send notice of redemption to the holders at least 30 days but not more than 60 days prior to the redemption date. The notice will specify:
