FORWARD-LOOKING AND CAUTIONARY STATEMENTS

We may from time to time make written or oral forward-looking statements, including in information included or incorporated by reference in this prospectus supplement and the attached prospectus. You can identify these forward-looking statements by use of words such as “strategy,” “expects,” “continues,” “plans,” “anticipates,” “believes,” “will,” “estimates,” “intends,” “projects,” “goals,” “targets,” “forecasts” and other words of similar meaning. You can also identify them by the fact that they do not relate strictly to historical or current facts.

We cannot guarantee that any forward-looking statement will be realized, although we believe we have been prudent in our plans and assumptions. Our reduced-risk products (“RRPs”) constitute a new product category in its early stages that is less predictable than our mature cigarette business. Achievement of future results is subject to risks, uncertainties and inaccurate assumptions. Should known or unknown risks or uncertainties materialize, or should underlying assumptions prove inaccurate, actual results could vary materially from those anticipated, estimated or projected. You should bear this in mind as you consider forward-looking statements and whether to invest in or remain invested in the notes. In connection with the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995, we have identified important factors in this prospectus supplement and in the documents incorporated by reference that, individually or in the aggregate, could cause actual results and outcomes to differ materially from those contained in any forward-looking statements made by us; any such statement is qualified by reference to these cautionary statements. We elaborate on these and other risks we face in this prospectus supplement and in the documents incorporated by reference, including our Quarterly Report onForm 10-Q for the quarter ended March 31, 2020, which discusses certain risks we face related to the COVID-19 pandemic. You should understand that it is not possible to predict or identify all risk factors. Consequently, you should not consider risks discussed in this prospectus supplement and in the documents incorporated by reference to be a complete discussion of all potential risks or uncertainties. We do not undertake to update any forward-looking statement that we may make from time to time, except in the normal course of our public disclosure obligations.

THE COMPANY

We are leading a transformation in the tobacco industry to create a smoke-free future and ultimately replace cigarettes with smoke-free products to the benefit of adults who would otherwise continue to smoke, society, the company and its shareholders. We are a leading international tobacco company engaged in the manufacture and sale of cigarettes, as well as smoke-free products and associated electronic devices and accessories, and other nicotine-containing products in markets outside the United States. In addition, we ship a version of our Platform 1 device and its consumables authorized by the U.S. Food and Drug Administration (“FDA”) to Altria Group, Inc. for sale in the United States under license. We are building a future on a new category of smoke-free products that, while not risk-free, are a much better choice than continuing to smoke. Through multidisciplinary capabilities in product development,state-of-the-art facilities and scientific substantiation, we aim to ensure that our smoke-free products meet adult consumer preferences and rigorous regulatory requirements. Our IQOS smoke-free product brand portfolio includesheat-not-burn tobacco and nicotine-containing vapor products.

We manage our business in six operating segments:

Our cigarettes are sold in more than 180 markets, and in many of these markets they hold the number one or number two market share position. We have a wide range of premium,mid-price andlow-price brands. Our portfolio comprises both international and local brands. In addition to the manufacture and sale of cigarettes, we are engaged in the development and commercialization of RRPs. RRPs is the term we use to refer to products that present, are likely to present, or have the potential to present less risk of harm to smokers who switch to these products versus continuing smoking.

Our principal executive offices are located at Philip Morris International Inc., 120 Park Avenue, New York, New York 10017-5579, our telephone number is +1(917) 663-2000 and our website is www.pmi.com.

“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 due 2023, the notes due 2025 or the notes due 2030 to be redeemed, as applicable (assuming for this purpose that the notes due 2023 matured on May 1, 2023, the notes due 2025 matured on April 1, 2025 and the notes due 2030 matured on February 1, 2030) 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.

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by us.

“Reference Treasury Dealer” means each of Citigroup Global Markets Inc., Goldman Sachs & Co. LLC and Mizuho Securities USA 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;

S-11

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 the series of notes due 2023, the series of notes due 2025 or the series of notes due 2030 are to be redeemed, the notes to be redeemed, as applicable, shall be selected by the trustee by lot, pro rata or by such method as the trustee shall deem fair and appropriate in each case in accordance with the applicable procedures of DTC. The trustee shall not be responsible for calculating the “make-whole” premium.

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.

Book-Entry Notes

We have obtained the information in this section concerning DTC, Clearstream and Euroclear, and the book-entry system and procedures from sources that we believe to be reliable, but we take no responsibility for the accuracy of this information.

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, or 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, or the Exchange Act. DTC holds securities that its participants, or 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.

S-12

Direct DTC Participants, or DTC Direct Participants, include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation, which is owned by the users of its regulated subsidiaries. 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 issuance 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 of notes beneficially owned by the DTC Participants. Any dealers, underwriters or agents participating in the distribution of the notes will designate the accounts to be credited. Ownership of beneficial interests in a registered global note will be shown on, and the transfer of ownership interests will be effected only through, records maintained by DTC, with respect to interests of DTC Participants, and on the records of DTC Participants, with respect to interests of persons holding through DTC Participants.

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. Such laws may impair the ability to own, transfer or pledge beneficial interests in a global note.

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

S-13

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 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. As a professional depositary, Clearstream is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Sector (Commission de Surveillance du Secteur Financier). Clearstream Participants are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations and may include the underwriters. Indirect access to Clearstream is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Clearstream Participant, either directly or indirectly.

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

The Terms and Conditions Governing Use of Euroclear and the related Operating Procedures of the Euroclear System, or the Euroclear Terms and Conditions, and applicable Belgian law govern securities clearance accounts and cash accounts with the Euroclear Operator. Specifically, these terms and conditions govern transfers of securities and cash within Euroclear, 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.

S-14

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

Global Clearance and Settlement Procedures

Initial settlement for the notes will be made in immediately available funds. Secondary market trading between the participants in the Depositary will occur in the ordinary way in accordance with the Depositary’s rules and will be settled in immediately available funds using DTC’sSame-Day Funds Settlement System. Secondary market trading between Clearstream Participants and/or Euroclear Participants will occur in the ordinary way in accordance with the applicable rules and operating procedures of Clearstream and Euroclear and will be settled using the procedures applicable to conventional Eurobonds in immediately available funds.

Cross-market transfers between persons holding directly or indirectly through DTC on the one hand, and directly or indirectly through Clearstream or Euroclear Participants, on the other, will be effected in DTC in accordance with the DTC rules on behalf of the relevant European international clearing system by its U.S. depositary; however, such cross-market transactions will require delivery of instructions to the relevant European international clearing system by the counterparty in such system in accordance with its rules and procedures and within its established deadlines (European time). The relevant European international clearing system will, if the transaction meets its settlement requirements, deliver instructions to its U.S. depositary to take action to effect final settlement on its behalf by delivering interests in the notes to or receiving interests in the notes from DTC, and making or receiving payment in accordance with normal procedures forsame-day funds settlement applicable to DTC. Clearstream Participants and Euroclear Participants may not deliver instructions directly to DTC.

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

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

Notices

Notices to holders of the notes will be sent to the registered holders and mailed, first class postage prepaid, or by email, at his or her physical address or email address as they appear in the security registrar for the notes.

Restrictive Covenants

The indenture limits the amount of liens (subject to certain exceptions described in “Description of Debt Securities—Restrictive Covenants” in the attached prospectus) that we or our Subsidiaries may incur or otherwise create, in order to secure indebtedness for borrowed money, upon any Principal Facility or any shares of capital stock that any of our Subsidiaries owning any Principal Facility has issued to us or any of our Subsidiaries. If we or any of our Subsidiaries incur such liens, then we will secure the debt securities to the same extent and in the same proportion as the debt that is secured by such liens. Notwithstanding the foregoing, we and/or any of our Subsidiaries may create, assume or incur liens that would otherwise be subject to the restriction

S-15

described in this paragraph, 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. The indenture also restricts our ability to engage in Sale and Leaseback Transactions under certain circumstances. See “Description of Debt Securities—Restrictive Covenants—Sale and Leaseback Transactions” in the attached prospectus.

At March 31, 2020, our Consolidated Net Tangible Assets were $11.9 billion.

Payment of Additional Amounts

We will, subject to the exceptions and limitations set forth below, pay to the beneficial owner of any note who is anon-United States person (as defined below) such additional amounts as may be necessary to ensure that every net payment on such note, after deduction or withholding by us or any of our paying agents for or on account of any present or future tax, assessment or other governmental charge imposed upon or as a result of such payment by the United States or any political subdivision or taxing authority of the United States, will not be less than the amount provided in such note to be then due and payable. However, we will not pay additional amounts if the beneficial owner is subject to taxation solely for reasons other than its ownership of the note, nor will we pay additional amounts for or on account of:

(a) any tax, assessment or other governmental charge that is imposed or withheld solely by reason of the existence of any present or former connection (other than the mere fact of being a beneficial owner of a note) between the beneficial owner (or between 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) of a note and the United States, including, without limitation, such beneficial owner (or such fiduciary, settlor, beneficiary, person holding a power, member or shareholder) being or having been a citizen or resident of the United States or treated as being or having been a resident thereof;

(b) 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) (1) being or having been present in, or engaged in a trade or business in, the United States, (2) being treated as having been present in, or engaged in a trade or business in, the United States, or (3) having or having had a permanent establishment in the United States;

(c) 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 foreigntax-exempt organization, or being a corporation that accumulates earnings to avoid United States federal income tax;

(d) 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, or the Code;

(e) 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;

S-16

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

(g) 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;

(h) 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;

(i) 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;

(j) 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;

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

(l) any combination of items (a), (b), (c), (d), (e), (f), (g), (h), (i), (j) and (k).

In addition, we will not pay additional amounts to a beneficial owner of a note that is a fiduciary, partnership, limited liability company or other fiscally transparent entity, or to a beneficial owner of a note that is not the sole beneficial owner of such note, as the case may be. This exception, however, will apply only to the extent that a beneficiary or settlor with respect to the fiduciary, or a beneficial owner or member of the partnership, limited liability company or other fiscally transparent entity, would not have been entitled to the payment of an additional amount had the beneficiary, settlor, beneficial owner or member received directly its beneficial or distributive share of the payment. The term “beneficial owner” includes any person holding a note on behalf of or for the account of a beneficial owner.

As used herein, the term“non-United States person” means a person that is not a United States person. The term United States person means a citizen or resident of the United States, a corporation or partnership created or organized in or under the laws of the United States or any political subdivision thereof, an estate the income of which is subject to United States federal income taxation regardless of its source, a trust subject to the primary supervision of a court within the United States and the control of one or more United States persons as described in Section 7701(a)(30) of the Code, or a trust that existed on August 20, 1996, and elected to continue its treatment as a domestic trust. “United States” means the United States of America (including the States and the District of Columbia), its territories, its possessions and other areas subject to its jurisdiction (including the Commonwealth of Puerto Rico).

Redemption for Tax Reasons

We may redeem a series of notes prior to maturity in whole, but not in part, on not more than 60 days’ notice and not less than 30 days’ notice at a redemption price equal to the principal amount of such notes plus any accrued interest and additional amounts to the date fixed for redemption if:

S-17

and we in our business judgment determine that such obligations cannot be avoided by the use of reasonable measures available to us.

If we exercise our option to redeem a series of notes, we will deliver to the trustee a certificate signed by an authorized officer stating that we are entitled to redeem the notes and the written opinion of independent legal counsel if required.

CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following summary describes generally the material United States federal income and, in the case ofnon-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 themark-to-market method of accounting for your securities holdings, person subject to the 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 ornon-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, or 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.

We urge prospective investors in the notes to consult their tax advisors regarding the United States federal, state, local andnon-United States income and other tax considerations of acquiring, holding and disposing of the notes.

United States Holders

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:

Payments of Interest

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.

S-19

Sale, Exchange, Redemption or Disposition of a Note

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 other taxable disposition, other than amounts, if any, attributable to accrued but unpaid stated interest and (ii) your adjusted tax basis in the note. Your adjusted tax basis in a note generally will equal the cost of the note to you. The gain or loss you recognize on the sale, exchange, redemption or other taxable disposition of a note generally will be capital gain or loss and will be long-term capital gain or loss if, at the time of the sale, exchange, redemption or other taxable disposition, you have held the note for more than one year. Under current United States federal income tax law, net long-term capital gains realized by taxpayers that are individuals, estates or trusts are eligible for taxation at preferential rates. The distinction between capital gain or loss and ordinary income or loss also is relevant for purposes of the limitation on the deductibility of capital losses.

Backup Withholding and Information Reporting

Unless you are an exempt recipient, a backup withholding tax 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 FormW-9), (ii) have not been notified by the IRS that you have failed to properly report payments of interest and dividends and (iii) in certain circumstances, 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.

Unearned Income Medicare Contribution

A tax of 3.8 percent 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.

Non-United States Holders

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).

S-20

Payments of Interest

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:

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 FormW-8BEN orW-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 tonon-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 FormW-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.

In addition, regardless of whether we qualify as an 80/20 company, you may qualify for an exemption from, or a reduced rate of, United States federal withholding tax under a United States income tax treaty. In general, this exemption or reduced rate of tax applies only if you provide a properly completed IRS FormW-8BEN orW-8BEN-E or substantially similar form claiming benefits under an applicable income tax treaty.

S-21

Sale, Exchange, Redemption or Disposition of Notes

You generally will not be subject to United States federal income tax on any gain realized upon your sale, exchange, redemption or other taxable disposition of notes unless:

Gain that is effectively connected with your conduct of a trade or business within the United States generally will be subject to United States federal income tax, net of certain deductions, at the same rates applicable to United States persons. If you are a corporation, the branch profits tax also may apply to such effectively connected gain. If the gain from the sale or disposition of your notes is effectively connected with your conduct of a trade or business in the United States but under an applicable income tax treaty is not attributable to a permanent establishment you maintain in the United States, your gain may be exempt from United States tax under the treaty. If you are described in the second bullet point above, you generally will be subject to United States tax at a rate of 30% on the gain realized, although the gain may be offset by some United States source capital losses realized during the same taxable year.

Backup Withholding and Information Reporting

The amount of interest we pay to you on notes will be reported to you and to the IRS annually on an IRS Form1042-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 tax and certain other information reporting requirements apply to payments of interest and certain reportable payments, unless an exemption applies. Backup withholding and information reporting will not apply to payments we make to you if you have provided under penalties of perjury the required certification of yournon-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 enumerated 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 false, 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.

S-22

Estate Tax

A note held by an individual who at the time of death is anon-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.

Foreign Account Tax Compliance Act

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 certainnon-U.S. entities (whether suchnon-U.S. entities are beneficial owners or intermediaries), including certain foreign financial institutions and investment funds, unless suchnon-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 beneficial United States owners (in the case ofnon-financial foreign entities). Under proposed regulations promulgated by the Treasury Department on December 13, 2018, which state that taxpayers may rely on the proposed regulations until final regulations are issued, FATCA withholding does not apply to payments of gross proceeds from a disposition of a debt instrument. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States with respect to FATCA may be subject to different rules. In addition, under certain circumstances, anon-United States Holder might be eligible for refunds or credits of any taxes imposed pursuant to FATCA. Prospective purchasers of the notes should consult their own tax advisors regarding these withholding and reporting provisions.

S-23

UNDERWRITING

Subject to the terms and conditions set forth in the terms agreement dated the date of this prospectus supplement, which incorporates by reference the underwriting agreement dated as of April 25, 2008, each of the underwriters named below, for whom Banca IMI S.p.A., BBVA Securities Inc., Citigroup Global Markets Inc., Deutsche Bank Securities Inc., Goldman Sachs & Co. LLC, Mizuho Securities USA LLC and SMBC Nikko Securities America, Inc. are acting as representatives, has severally agreed to purchase, and we have agreed to sell to each underwriter, the respective principal amount of each series of notes as set forth opposite the name of each underwriter below.

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.

We have been advised by the underwriters that the underwriters propose initially to offer some of the notes to the public at the public offering prices set forth on the cover page of this prospectus supplement and may offer some of the notes to certain dealers at the public offering price less concessions not in excess of 0.125%, in the case of the notes due 2023, not in excess of 0.180%, in the case of the notes due 2025 and not in excess of 0.250%, in the case of the notes due 2030. The underwriters may allow, and these dealers may reallow, concessions not in excess of 0.050%, in the case of the notes due 2023, not in excess of 0.100%, in the case of the notes due 2025 and not in excess of 0.150%, in the case of the notes due 2030, of the principal amount of the notes on sales of the notes to certain other dealers. After the initial offering of the notes to the public, the underwriters may change the public offering price and concessions. The offering of the notes by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part.

The following table shows the underwriting discounts and commissions that we are to pay to the underwriters in connection with this offering (expressed as a percentage of the principal amount of the notes).

In connection with the offering of the notes, the underwriters or their respective affiliates may purchase and sell the notes in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the stabilizing underwriters of a greater number of notes than they are required to purchase in the offering. Stabilizing transactions consist of certain bids or purchases made for the purpose of preventing or retarding a decline in the market price of the notes while the offering is in progress.

S-24

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 price of the notes to be higher than the price that otherwise would exist in the open market in the absence of such transactions. These transactions may be effected in theover-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 price 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 $2,300,000.

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.

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 May 1, 2020, 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).

The notes are new issues of securities with no established trading market. The notes will not be listed on any securities exchange or included in any automated quotation system. We cannot assure you that the notes will have a liquid trading market. We have been advised by the underwriters that they intend to make a market in the notes, but they are not obligated to do so and may discontinue such market-making at any time without notice.

FORWARD-LOOKING AND CAUTIONARY STATEMENTS

We may from time to time make written or oral forward-looking statements, including in information included or incorporated by reference in this prospectus and the applicable prospectus supplement. You can identify these forward-looking statements by use of words such as “strategy,” “expects,” “continues,” “plans,” “anticipates,” “believes,” “will,” “estimates,” “intends,” “projects,” “goals,” “targets” and other words of similar meaning. You can also identify them by the fact that they do not relate strictly to historical or current facts.

We cannot guarantee that any forward-looking statement will be realized, although we believe we have been prudent in our plans and assumptions. Our reduced-risk products (“RRPs”) constitute a new product category in its early stages that is less predictable than our mature cigarette business. Achievement of future results is subject to risks, uncertainties and inaccurate assumptions. Should known or unknown risks or uncertainties materialize, or should underlying assumptions prove inaccurate, actual results could vary materially from those anticipated, estimated or projected. You should bear this in mind as you consider forward-looking statements and whether to invest in or remain invested in our securities. In connection with the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995, we have identified important factors in the documents incorporated by reference that, individually or in the aggregate, could cause actual results and outcomes to differ materially from those contained in any forward-looking statements made by us; any such statement is qualified by reference to these cautionary statements. We elaborate on these and other risks we face in the documents incorporated by reference. You should understand that it is not possible to predict or identify all risk factors. Consequently, you should not consider risks discussed in the documents incorporated by reference to be a complete discussion of all potential risks or uncertainties. We do not undertake to update any forward-looking statement that we may make from time to time, except in the normal course of our public disclosure obligations.

THE COMPANY

General

We are leading a transformation in the tobacco industry to create a smoke-free future and ultimately replace cigarettes with smoke-free products to the benefit of adults who would otherwise continue to smoke, society, the company and its shareholders. We are a leading international tobacco company engaged in the manufacture and sale of cigarettes, as well as smoke-free products and associated electronic devices and accessories, and other nicotine-containing products in markets outside the United States. In addition, we ship a version of our Platform 1 device and its consumables authorized by the U.S. Food and Drug Administration (“FDA”) to Altria Group, Inc. for sale in the United States under license. We are building a future on a new category of smoke-free products that, while not risk-free, are a much better choice than continuing to smoke. Through multidisciplinary capabilities in productdevelopment, state-of-the-art facilities and scientific substantiation, we aim to ensure that our smoke-free products meet adult consumer preferences and rigorous regulatory requirements. OurIQOS smoke-free product brand portfolioincludes heat-not-burn tobacco and nicotine-containing vapor products.

We manage our business in six operating segments:

Our cigarettes are sold in more than 180 markets, and in many of these markets they hold the number one or number two market share position. We have a wide range ofpremium, mid-price and low-price brands. Our portfolio comprises both international and local brands. In addition to the manufacture and sale of cigarettes, we are engaged in the development and commercialization of RRPs. RRPs is the term we use to refer to products that present, are likely to present, or have the potential to present less risk of harm to smokers who switch to these products versus continuing smoking.

Our principal executive offices are located at Philip Morris International Inc., 120 Park Avenue, New York, New York 10017-5579, our telephone number is +1 (917) 663 - 2000 and our website is www.pmi.com. The information contained in, or that can be accessed through, our website is not a part of this prospectus or any prospectus supplement.

Other

We are a legal entity separate and distinct from our direct and indirect subsidiaries. Accordingly, our right, and thus the right of our creditors and stockholders, to participate in any distribution of the assets or earnings of any subsidiary is subject to the prior rights of creditors of such subsidiary, except to the extent that claims of our company itself as a creditor may be recognized. As a holding company, our principal sources of funds, including funds to make payment on our debt securities, are from the receipt of dividends and repayment of debt from our subsidiaries. Our principal wholly owned and majority-owned subsidiaries currently are not limited by long-term debt or other agreements in their ability to pay cash dividends or to make other distributions with respect to their common stock that are otherwise compliant with law.

1

RISK FACTORS

Our business is subject to uncertainties and risks. You should carefully consider and evaluate all of the information included and incorporated by reference in this prospectus, including the risk factors incorporated by reference to our Annual Report onForm10-K for the year ended December 31, 2019, as well as any risk factors we may describe in any subsequent periodic reports or information we file with the SEC. It is possible that our business, financial condition, liquidity or results of operations could be materially adversely affected by any of these risks.

2

USE OF PROCEEDS

Unless we otherwise state in the applicable prospectus supplement, we intend to use the net proceeds from the sale of the debt securities and debt warrants and the net proceeds, if any, from the exercise of debt warrants, for general corporate purposes. General corporate purposes may include repayment of debt, additions to working capital, capital expenditures, investments in our subsidiaries, possible acquisitions and the repurchase, redemption or retirement of securities, including shares of our common stock. The net proceeds may be temporarily invested or applied to repay short-term or revolving debt prior to use.

We expect to issue long-term and short-term debt from time to time. The nature and amount of ourlong-term and short-term debt and the proportionate amount of each can be expected to vary from time to time as a result of business requirements, market conditions and other factors.

DESCRIPTION OF DEBT SECURITIES

The debt securities covered by this prospectus will be our direct unsecured obligations. The debt securities will be issued in one or more series under an indenture dated as of April 25, 2008 between us and HSBC Bank USA, National Association, as trustee.

This prospectus briefly describes the material indenture provisions. Those descriptions are qualified in all respects by reference to the actual text of the indenture. For your reference, in the summary that follows, we have included references to section numbers of the indenture so that you can more easily locate these provisions. In cases where portions of the summary are taken from more than one section of the indenture, we have referred only to the section of the indenture that is principally applicable to that part of the summary. A copy of the indenture is listed as an exhibit to the registration statement of which this prospectus is a part and is incorporated herein by reference. See “Where You Can Find More Information” for information on how to obtain a copy. You should also refer to the Trust Indenture Act of 1939, or the Trust Indenture Act, certain terms of which are made part of the indenture by reference.

The material financial, legal and other terms particular to debt securities of each series will be described in the prospectus supplement relating to the debt securities of that series. The prospectus supplement relating to the debt securities of the series will be attached to the front of this prospectus. The following briefly summarizes the material provisions of the indenture and the debt securities, other than pricing and related terms that will be disclosed in an accompanying prospectus supplement. The prospectus supplement will also state whether any of the terms summarized below do not apply to the series of debt securities being offered. You should read the more detailed provisions of the indenture, including the defined terms, for provisions that may be important to you. You should also read the particular terms of a series of debt securities, which will be described in more detail in the applicable prospectus supplement.

Prospective purchasers of debt securities should be aware that special United States federal income tax, accounting and other considerations not addressed in this prospectus may be applicable to instruments such as the debt securities. The prospectus supplement relating to an issue of debt securities will describe these considerations, if they apply.

Capitalized terms used below are defined under “Defined Terms.” In this “Description of Debt Securities” section, references to “we,” “us” and “our” are only to Philip Morris International Inc. and not its subsidiaries.

General

The debt securities will rank equally with all of our other unsecured and unsubordinated debt. The indenture does not limit the amount of debt we may issue under the indenture and provides that additional debt securities may be issued up to the aggregate principal amount authorized by a board resolution. We may issue the debt securities from time to time in one or more series with the same or various maturities, at par, at a discount or at a premium. The prospectus supplement relating to any debt securities being offered will include specific terms relating to the offering, including the particular amount, price and other terms of those debt securities. These terms will include some or all of the following:

4

or, in each case, their method of determination;

5

(Section 301)

We may issue debt securities as OID debt securities. OID debt securities bear no interest or bear interest at below-market rates and are sold at a discount below their stated principal amount. If we issue OID debt securities, the prospectus supplement will contain the issue price of the securities and the rate at which and the date from which discount will accrete.

We may also issue indexed debt securities. Payments of principal of, and any premium and interest on, indexed debt securities are determined with reference to the rate of exchange between the currency or currency unit in which the debt security is denominated and any other currency or currency unit specified by us, to the relationship between two or more currencies or currency units, to the price of one or more specified securities or commodities, to one or more securities or commodities exchange indices or other indices or by other similar methods or formulas, all as specified in the prospectus supplement. (Section 301)

We may issue debt securities other than the debt securities described in this prospectus. There is no requirement that any other debt securities that we issue be issued under the indenture. Thus, any other debt securities that we issue may be issued under other indentures or documentation containing provisions different from those included in the indenture or applicable to one or more issues of the debt securities described in this prospectus.

Consolidation, Merger or Sale

Under the indenture, we may not consolidate with or merge into any other corporation or convey or transfer our properties and assets substantially as an entirety to any person unless:

(Section 801)

The successor corporation will assume all of our obligations under the indenture as if it were an original party to the indenture. After assuming such obligations, the successor corporation will have all of our rights and powers under the indenture. (Section 802)

6

Waivers Under the Indenture

Under the indenture, the holders of not less than a majority in aggregate principal amount of all affected series of the outstanding debt securities (voting as a single class), may on behalf of all holders of such affected series:

(Section 513)

Events of Default

When we use the term “Event of Default” in the indenture with respect to a particular series of debt securities, we mean any of the following:

(Section 501)

The supplemental indenture or the form of security for a particular series of debt securities may include additional Events of Default or changes to the Events of Default described above. The Events of Default applicable to a particular series of debt securities will be described in the prospectus supplement relating to such series.

A default with respect to a single series of debt securities under the indenture will not necessarily constitute a default with respect to any other series of debt securities issued under the indenture. A default under our other indebtedness will not be a default under the indenture. The trustee may withhold notice to the holders of debt securities of any default, except for defaults that involve our failure to pay principal or any premium or interest, if it determines in good faith that the withholding of notice is in the interest of the holders. (Section 602)

If an Event of Default for any series of debt securities occurs and continues (other than an Event of Default involving our bankruptcy, insolvency or reorganization), either the trustee or the holders of at least 25% in

7

aggregate principal amount of all outstanding series of the debt securities to which it is applicable or, if such default is not applicable to all series of the debt securities, the holders of at least 25% in principal amount of all series to which it is applicable (in each case voting as a single class) may require us upon notice in writing to us, to immediately repay the entire principal (or, in the case of (a) OID debt securities, a lesser amount as may be provided in those OID debt securities or (b) indexed debt securities, an amount determined by the terms of those indexed debt securities), of all the debt securities of such series together with accrued interest on the debt securities.

If an Event of Default occurs which involves our bankruptcy, insolvency or reorganization, then all unpaid principal amounts (or, if the debt securities are (a) OID debt securities, a lesser amount as may be provided in those OID debt securities or (b) indexed debt securities, an amount determined by the terms of those indexed debt securities), of all the debt securities of such series together with accrued interest on the debt securities and accrued interest on all debt securities of each series then outstanding will immediately become due and payable, without any action by the trustee or any holder of debt securities. (Section 502)

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)

Other than its duties in case of an Event of Default, the trustee is not obligated to exercise any of its rights or powers under the indenture at the request, order or direction of any holders, unless the holders offer the trustee reasonable indemnity. (Section 507) The holders of a majority in principal amount outstanding of any series of debt securities may, subject to certain limitations, direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any power conferred upon the trustee, for any series of debt securities. (Section 512)

The indenture requires us to file each year with the trustee, an officer’s certificate that states that:

A judgment for money damages by courts in the United States, including a money judgment based on an obligation expressed in a foreign currency, will ordinarily be rendered only in U.S. dollars. New York statutory law provides that a court shall render a judgment or decree in the foreign currency of the underlying obligation and that the judgment or decree shall be converted into U.S. dollars at the exchange rate prevailing on the date of entry of the judgment or decree. If a court requires a conversion to be made on a date other than a judgment date, the indenture requires us to pay additional amounts necessary to ensure that the amount paid in U.S. dollars to a holder is equal to the amount due in such foreign currency or currency unit. (Section 515)

Payment and Transfer

We will pay the principal of, and any premium and interest on, debt securities at the place or places that we will designate for such purposes. We will make payment to the persons in whose names the debt securities are registered on the close of business on the day or days that we will specify in accordance with the indenture. We will pay the principal of, and any premium on, debt securities only against surrender of those debt securities. Any other payments will be made as set forth in the applicable prospectus supplement. Holders may transfer or exchange debt securities at the corporate trust office of the trustee or at any other office or agency, maintained for such purposes, without the payment of any service charge except for any tax or governmental charge. (Section 307)

8

Restrictive Covenants

The indenture includes the following restrictive covenants:

Limitations on Liens

The indenture limits the amount of liens that we or our Subsidiaries may incur or otherwise create, in order to secure indebtedness for borrowed money, upon any Principal Facility or any shares of capital stock that any of our Subsidiaries owning any Principal Facility has issued to us or any of our Subsidiaries. If we or any of our Subsidiaries incur such liens, then we will secure the debt securities to the same extent and in the same proportion as the debt that is secured by such liens. This covenant does not apply, however, to any of the following:

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)

At December 31, 2019, our Consolidated Net Tangible Assets were $14.1 billion.

Sale and Leaseback Transactions

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 ofnon-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)

9

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.

Defined Terms

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)

We define Consolidated Net Tangible Assets as the excess over current liabilities of all assets appearing on our most recent quarterly or annual consolidated balance sheet, less goodwill and other intangible assets and the minority interests of others in Subsidiaries. (Section 101)

Global Securities

We may issue the debt securities in whole or in part in the form of one or more global securities that will be deposited with, or on behalf of, a depositary identified in the applicable prospectus supplement.

We may issue the global securities in either temporary or permanent form. We will describe the specific terms of the depositary arrangement with respect to a series of debt securities in the applicable prospectus supplement. We anticipate that the following provisions will apply to all depositary arrangements.

Once a global security is issued, the depositary will credit on its book-entry system the respective principal amounts of the individual debt securities represented by that global security to the accounts of institutions that have accounts with the depositary. These institutions are known as participants.

The underwriters for the debt securities will designate the accounts to be credited. However, if we have offered or sold the securities either directly or through agents, we or the agents will designate the appropriate accounts to be credited.

Ownership of beneficial interests in a global security will be limited to participants or persons that may hold beneficial interests through participants. Ownership of beneficial interests in a global security will be shown on,

10

and the transfer of that ownership will be effected only through, records maintained by the depositary’s participants or persons that may hold through participants. The laws of some states require that certain purchasers of debt securities take physical delivery of securities. Those laws may limit the market for beneficial interests in a global security.

So long as the depositary for a global security, or its nominee, is the registered owner of a global security, the depositary or nominee will be considered the sole owner or holder of the debt securities represented by the global security for all purposes under the indenture. Except as provided in the applicable prospectus supplement, owners of beneficial interests in a global security:

Payments of principal of, and any premium and interest on, the individual debt securities registered in the name of the depositary or its nominee will be made to the depositary or its nominee as the registered owner of that global security.

Neither we nor the trustee will have any responsibility or liability for any aspect of the records relating to, or payments made on account of, beneficial ownership interests of a global security, or for maintaining, supervising or reviewing any records relating to beneficial ownership interests and each of us and the trustee may act or refrain from acting without liability on any information provided by the depositary. (Section 308)

We expect that the depositary, after receiving any payment of principal of, and any premium and interest on, a global security, will immediately credit the accounts of the participants with payments in amounts proportionate to their respective holdings in principal amount of beneficial interest in a global security as shown on the records of the depositary. We also expect that payments by participants to owners of beneficial interests in a global security will be governed by standing customer instructions and customary practices, as is now the case with debt securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of such participants.

Debt securities represented by a global security will be exchangeable for debt securities in definitive form of like tenor in authorized denominations only if:

Unless and until a global security is exchanged in whole or in part for debt securities in definitive certificated form, it may not be transferred or exchanged except as a whole by the depositary.

You may transfer or exchange certificated securities at any office that we maintain for this purpose in accordance with the terms of the indenture. We will not charge a service fee for any transfer or exchange of certificated securities, but we may require payment of a sum sufficient to cover any tax or other governmental charge that we are required to pay in connection with a transfer or exchange. (Section 305)

Registration of Transfer

You may effect the transfer of certificated securities and the right to receive the principal of, and any premium and interest on, certificated securities only by surrendering the certificate representing those certificated

11

securities and either reissuance by us or the trustee of the certificate to the new holder or the issuance by us or the trustee of a new certificate to the new holder.

We are not required to:

(Section 305)

Exchange

At your option, you may exchange your debt securities of any series, except a global security, for an equal principal amount of other debt securities of the same series having authorized denominations upon surrender to our designated agent.

We may at any time exchange debt securities issued as one or more global securities for an equal principal amount of debt securities of the same series in definitive form. In this case, we will deliver to the holders new debt securities in definitive registered form in the same aggregate principal amount as the global securities being exchanged.

The depositary of the global securities may also decide at any time to surrender one or more global securities in exchange for debt securities of the same series in definitive form, in which case we will deliver the new debt securities in definitive form to the persons specified by the depositary, in an aggregate principal amount equal to, and in exchange for, each person’s beneficial interest in the global securities.

Notwithstanding the above, we will not be required to exchange any debt securities if, as a result of the exchange, we would suffer adverse consequences under any United States law or regulation. (Section 305)

Defeasance

Legal Defeasance

Unless otherwise specified in the prospectus supplement, we can legally release ourselves from all of our obligations, with certain limited exceptions, on any series of debt securities. This is called legal defeasance. In order to achieve legal defeasance:

12

Covenant Defeasance

Unless specified in the prospectus supplement, we can make the same type of deposit described above under “Defeasance—Legal Defeasance” and be released from the restrictive covenants on any series of debt securities. This is called covenant defeasance. In order to achieve covenant defeasance:

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

(Sections402-404)

Payments of Unclaimed Moneys

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)

13

Supplemental Indentures Not Requiring Consent of Holders

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

(Section 901)

Supplemental Indentures Requiring Consent of Holders

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:

14

(Section 902)

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.

Redemption

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:

(Section 1104)

On or before any redemption date, we will deposit an amount of money with the trustee or with a paying agent sufficient to pay the redemption price. (Section 1105)

If less than all the debt securities are being redeemed, we may select the particular series to be redeemed; if less than all the debt securities of a series are being redeemed, the trustee shall select the debt securities to be redeemed using a method it considers fair and appropriate. (Section 1103) After the redemption date, holders of debt securities which were redeemed will have no rights with respect to the debt securities except the right to receive the redemption price and any unpaid interest to the redemption date. (Section 1106)

Concerning the Trustee

HSBC Bank USA, National Association is the trustee under the indenture. HSBC Bank USA, National Association or its affiliates make loans to and perform certain other services for us and certain of our subsidiaries and affiliates. Among other services, HSBC Bank USA, National Association or its affiliates provide us and our affiliates with investment banking and cash management services, foreign exchange and investment custody account services, and participate in our credit facilities and those of our affiliates.

Governing Law

The laws of the State of New York govern the indenture and will govern the debt securities. (Section 112)

15

DESCRIPTION OF DEBT WARRANTS

We may issue debt warrants in registered certificated form for the purchase of debt securities. We may issue debt warrants separately or together with any debt securities offered by any prospectus supplement. If issued together with any debt securities, debt warrants may be attached to or separate from such debt securities. Debt warrants will be issued under debt warrant agreements to be entered into between us and a bank or trust company, as debt warrant agent, all as set forth in the prospectus supplement relating to the particular issue of debt warrants. The debt warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants. A form of debt warrant agreement, including a form of debt warrant certificate, reflecting the particular terms and provisions of a particular issue of debt warrants, will be filed with the SEC in connection with the offering and incorporated by reference in the registration statement of which this prospectus is a part. See “Where You Can Find More Information” for information on how to obtain copies of any form of debt warrant agreement that has been filed. Summaries of certain provisions of the debt warrant agreements and debt warrant certificates follow. You should read the more detailed provisions of the forms of debt warrant agreement and debt warrant certificate and any additional terms relating to the particular issue of debt warrants, which will be described in detail in the applicable prospectus supplement, for additional information before you buy any debt warrants.

General

The prospectus supplement will describe the terms of the debt warrants offered thereby, the debt warrant agreements relating to such debt warrants and the debt warrant certificates representing such debt warrants, including the following:

Debt warrant certificates may be exercised, and those that have been issued separately or, if issued together with debt securities, once detachable, may be exchanged for new debt warrant certificates of different denominations and may be presented for registration of transfer at the corporate trust office of the debt warrant agent or any other office indicated in the applicable prospectus supplement. A debt warrant certificate that is not immediately detachable from a debt security may be exchanged or transferred only with the debt securities to which it was initially attached, and only in connection with the exchange or transfer of such debt securities. Debt warrants for the purchase of debt securities will be in registered form only.

16

Exercise of Debt Warrants

Each debt warrant will entitle its holder to purchase for cash such principal amount of debt securities at such exercise price as will in each case be set forth in, or calculable from, the applicable prospectus supplement relating to the debt warrants. Each holder of a debt warrant may exercise it at any time up to 5:00 p.m., New York City time, on the debt warrant expiration date set forth in the applicable prospectus supplement. After such time, or such later date to which such debt warrant expiration date may be extended by us, unexercised debt warrants will be void.
