(b) Notwithstanding any other provision in the Indenture, no Global Security may be exchanged in whole or in part for Notes registered, and no transfer of a Global Security in whole or in part may be registered, in the name of any Person other than the Depository for such Global Security or a nominee thereof unless (A) such Depository (1) has notified the Issuer that it is unwilling or unable to continue as Depository for such Global Security and no successor Depository has been appointed within 90 days after such notice or (2) ceases to be a “clearing agency” registered under Section 17A of the Exchange Act when the Depositary is required to be so registered to act as the Depositary and so notifies the Issuer, and no successor Depositary has been appointed within 90 days after such notice, (B) the Issuer determines at any time that the Notes shall no longer be represented by Global Securities and shall inform such Depositary of such determination and participants in such Depositary elect to withdraw their beneficial interests in the Notes from such Depositary, following notification by the Depositary of their right to do so, or (C) such exchange is made upon request by or on behalf of the Depositary in accordance with customary procedures, following the request of a Holder seeking to exercise or enforce its rights under the Notes during the continuance of an Event of Default.

(c) Subject to clause (b) above, any exchange of a Global Security for other Notes may be made in whole or in part, and all Notes issued in exchange for a Global Security or any portion thereof shall be registered in such names as the Depositary for such Global Security shall direct in writing to the Trustee.

(d) Every Note authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Security or any portion thereof shall be authenticated and delivered in the form of, and shall be, a Global Security, unless such Note is registered in the name of a Person other than the Depositary for such Global Security or a nominee thereof.

Notwithstanding the foregoing, nothing herein shall prevent the Issuer, the Trustee, the Paying Agent or the Registrar or any of their agents from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Members, the operation of customary practices of the Depositary governing the exercise of the rights of an owner of a beneficial interest in any Global Security.

Any interest accrued to such Redemption Date will be paid as specified in such notice.

(f) The following defined terms used in this Article VII shall, unless the context otherwise requires, have the meanings specified below.

“Comparable Government Bond” means, in relation to any Comparable Government Bond Rate calculation, at the discretion of an independent investment bank selected by the Issuer, a German Bundesanleihe security whose maturity is closest to the maturity of the Notes being redeemed (assuming that the Notes to be redeemed matured on the applicable Par Call Date), or if such independent investment bank in its discretion considers that such similar bond is not in issue, such other German Bundesanleihe security as such independent investment bank may, with the advice of three brokers of, or market makers in, German Bundesanleihe securities selected by such independent investment bank, determine to be appropriate for determining the Comparable Government Bond Rate.

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

The Issuer’s actions and determinations in determining the applicable Redemption Price shall be conclusive and binding for all purposes, absent manifest error.

(g) The Issuer will notify the Trustee of the Redemption Price promptly after the calculation thereof. The Trustee shall have no responsibility for any calculation, verification or determination in respect of the Redemption Price of any Notes, or any component thereof, and shall be entitled to receive, and fully-protected in relying upon, an Officer’s Certificate from the Issuer that states such Redemption Price.

Section 7.02 Par Call. Any time on or after the 2029 Par Call Date with respect to the 2029 Notes, the 2032 Par Call Date with respect to the 2032 Notes, the 2037 Par Call Date with respect to the 2037 Notes and the 2045 Par Call Date with respect to the 2045 Notes, the Issuer may redeem the applicable series of Notes, in whole, at any time, or in part, from time to time, at a Redemption Price equal to 100% of the principal amount of the Notes to be redeemed, plus, in each case, accrued and unpaid interest on the Notes being redeemed to, but excluding, such Redemption Date.

Section 7.03 Redemption for Tax Reasons. If, as a result of any change in, or amendment to, the laws (or any regulations or rulings promulgated under the laws) of the Taxing Jurisdiction (as defined herein) (or any taxing authority thereof or therein), or any change in, or amendments to, an official position regarding the application or interpretation of such laws, regulations or rulings, which change or amendment is announced or becomes effective on or after May 14, 2025, the Issuer becomes or, based upon a written opinion of independent tax counsel of recognized standing selected by the Issuer, will become obligated to pay Additional Amounts as described under Article X with respect to any series of the Notes, then the Issuer may at its option, having given not less than 10 nor more than 60 days prior notice to Holders, redeem, in whole, but not in part, the Notes of such applicable series at a redemption price equal to 100% of the principal amount, together with accrued and unpaid interest (including any Additional Amounts) on such Notes to, but excluding, the Redemption Date.

Interest. Pfizer Netherlands International Finance B.V., a private company with limited liability (besloten vennootschap met beperkte aansprakelijkheid) under Dutch law, with official seat (statutaire zetel) in Rotterdam, the Netherlands (herein called the “Issuer”, which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to The Bank of New York Depository (Nominees) Limited or registered assigns, the principal sum of ___________________ (€__________), as revised by the Schedule of Increases or Decreases in Global Security attached hereto, on May 19, 2029 and to pay interest thereon from May 19, 2025 or from the most recent Interest Payment Date to which interest has been paid or duly provided for, annually in arrears on May 19 in each year, commencing May 19, 2026, at the rate of 2.875% per annum, until the principal hereof is paid or made available for payment.

Method of Payment. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Record Date for such interest, which shall be the date that is the close of business (in London) on the Clearing System Business Day immediately preceding such Interest Payment Date, where “Clearing System Business Day” means a day on which Euroclear and Clearstream are open for business. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Record Date and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business (in London) on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice thereof having been given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture.

(herein called the “Parent Guarantor,” which term includes any successor Person under the Indenture) and The Bank of New York Mellon (herein called the “Trustee,” which term includes any successor trustee under the Indenture), as supplemented by a First Supplemental Indenture, dated as of May 19, 2025 (as so supplemented, herein called the “Indenture”), among the Issuer, the Parent Guarantor and the Trustee, to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Issuer, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof, initially limited in aggregate principal amount to €750,000,000.

Issuance in Euros. All payments of principal, premium, if any, and interest payments and Additional Amounts, if any, in respect of the Securities will be payable in euros. If on or after May 19, 2025, the euro is unavailable to the Issuer or the Parent Guarantor due to the imposition of exchange controls or other circumstances beyond their control or if the euro is no longer used by the then member states of the European Monetary Union that have adopted the euro as their currency or for the settlement of transactions by public institutions of or within the international banking community, then all payments in respect of the Securities will be made in U.S. Dollars until the euro is again available to the Issuer and the Parent Guarantor or is so used. In such circumstances, the amount payable on any date in euros will be converted into U.S. Dollars as determined by an agent appointed by the Issuer and shall be equal to the sum obtained by converting euros into U.S. Dollars at the exchange rate on the second Business Day preceding such Interest Payment Date or the second Business Day preceding the maturity of an installment of principal, as the case may be, or if no rate is quoted for euros, the last date such rate is quoted. Any payment in respect of Securities so made in U.S. Dollars will not constitute an Event of Default. Neither the Trustee nor the Paying Agent will be responsible for obtaining exchange or foreign currency rates, effecting conversions or otherwise handling redenominations.

Guarantee. This Security is entitled to the benefits of an unconditional and irrevocable guarantee by the Parent Guarantor for the benefit of the Holders. Reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and obligations thereunder of the Parent Guarantor, the Trustee and the Holders.

Optional Redemption. At the Issuer’s option, the Securities of this series may be redeemed, in whole, at any time, or in part, from time to time, prior to April 19, 2029 (one month prior to the Stated Maturity of the Securities (the “Par Call Date”; and the date of any such redemption a “Redemption Date”)), at a redemption price (the “Redemption Price”) (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

A-5

(a) 100% of the principal amount of the Securities being redeemed on that Redemption Date, and

(b) the sum of the present values of the remaining scheduled payments of principal and interest on the Securities being redeemed that would be due if such series of Securities matured on the Par Call Date (in each case not including the amount, if any, of accrued and unpaid interest to, but excluding, the Redemption Date) discounted to the Redemption Date on an annual basis (ACTUAL/ACTUAL (ICMA)) using a discount rate equal to the Comparable Government Bond Rate plus 15 basis points,

plus, in each of the cases of clauses (a) and (b) above, accrued and unpaid interest on the Securities being redeemed to, but excluding, such Redemption Date.

Any time on or after the Par Call Date, the Issuer may redeem the Securities, in whole, at any time, or in part, from time to time, at a Redemption Price equal to 100% of the principal amount of the Securities to be redeemed, plus accrued and unpaid interest on the Securities being redeemed to, but excluding, the Redemption Date.

If, as a result of any change in, or amendment to, the laws (or any regulations or rulings promulgated under the laws) of the Taxing Jurisdiction (or any taxing authority thereof or therein), or any change in, or amendments to, an official position regarding the application or interpretation of such laws, regulations or rulings, which change or amendment is announced or becomes effective on or after May 14, 2025, the Issuer becomes or, based upon a written opinion of independent tax counsel of recognized standing selected by the Issuer, will become obligated to pay Additional Amounts with respect to the Securities, then the Issuer may at its option, having given not less than 10 nor more than 60 days prior notice to Holders, redeem, in whole, but not in part, the Securities at a redemption price equal to 100% of the principal amount, together with accrued and unpaid interest (including any Additional Amounts) on such Securities to, but excluding, the Redemption Date.

The Redemption Price will be calculated on the basis of a 365-day year or a 366-day year, as applicable, and the actual number of days elapsed. Subject to the following paragraph, once notice of redemption is sent by the Issuer, the Securities called for redemption will become due and payable on the applicable Redemption Date at the applicable Redemption Price.

Any notice of redemption may, at the Issuer’s discretion, be subject to one or more conditions precedent, including completion of a corporate transaction. In such event, the related notice of redemption shall describe each such condition and, if applicable, shall state that, at the Issuer’s discretion, the date of redemption may be delayed until such time (including more than 60 days after the notice of redemption was given) as any or all such conditions shall be satisfied (or waived by the Issuer in its sole discretion), or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied or waived by the date of redemption, or by the date of redemption so delayed.

A-6

For purposes of determining the Redemption Price, the following definitions are applicable:

“Comparable Government Bond” means, in relation to any Comparable Government Bond Rate calculation, at the discretion of an independent investment bank selected by the Issuer, a German Bundesanleihe security whose maturity is closest to the maturity of the Securities being redeemed (assuming that the Securities to be redeemed matured on the applicable Par Call Date), or if such independent investment bank in its discretion considers that such similar bond is not in issue, such other German Bundesanleihe security as such independent investment bank may, with the advice of three brokers of, or market makers in, German Bundesanleihe securities selected by such independent investment bank, determine to be appropriate for determining the Comparable Government Bond Rate.

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

The Issuer’s actions and determinations in determining the Redemption Price shall be conclusive and binding for all purposes, absent manifest error.

The Issuer will notify the Trustee of the Redemption Price promptly after the calculation thereof. The Trustee shall have no responsibility for any calculation, verification or determination in respect of the Redemption Price of any Securities, or any component thereof, and shall be entitled to receive, and fully-protected in relying upon, an Officer’s Certificate from the Issuer that states such Redemption Price.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the procedures of the applicable clearing system) at least 10 days, but not more than 60 days, before the Redemption Date to each registered Holder of the Securities to be redeemed. The principal amount of a Security remaining outstanding after a redemption in part shall be €100,000 or an integral multiple of €1,000 in excess thereof.

Unless the Issuer defaults in payment of the Redemption Price, on and after the Redemption Date interest will cease to accrue on the Securities or portions thereof called for redemption.

If fewer than all of the Securities are to be redeemed, the Securities to be redeemed shall be selected in accordance with applicable procedures of Euroclear and/or Clearstream.

A-7

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

Defaults and Remedies. If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

Amendment, Modification and Waiver. The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Issuer and the Parent Guarantor and the rights of the Holders of the Securities of each series affected under the Indenture at any time by the Issuer, the Parent Guarantor and the Trustee with the consent of the Holders of a majority in principal amount of all series at the time Outstanding affected thereby (voting as one class). The Indenture contains provisions permitting the Holders of not less than a majority in principal amount of the Outstanding Securities of any series, with respect to which any default under the Indenture shall have occurred and be continuing, on behalf of the Holders of all the Outstanding Securities of such series, to waive, with certain exceptions, such past default with respect to such series and its consequences. The Indenture also permits the Holders of not less than a majority in principal amount of the Outstanding Securities of any series, on behalf of the Holders of all Outstanding Securities of such series, to waive compliance by the Issuer or the Parent Guarantor with certain provisions of the Indenture. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange therefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

Restrictive Covenants. The Indenture does not limit unsecured debt of the Parent Guarantor or any of its Subsidiaries (including the Issuer).

Denominations, Transfer and Exchange. The Securities of this series are issuable only in registered form without coupons in denominations of €100,000 and in integral multiples of €1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registerable in the Security Register, upon surrender of this Security for registration of transfer at the Registrar accompanied by a written request for transfer in form satisfactory to the Issuer and the Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

No service charge shall be made for any such registration of transfer or exchange, but the Issuer may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

A-8

Persons Deemed Owners. Prior to due presentment of this Security for registration of transfer, the Issuer, the Trustee and any agent of the Issuer or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Issuer, the Trustee nor any such agent shall be affected by notice to the contrary.

Miscellaneous. The Indenture and this Security shall be governed by and construed in accordance with the law of the State of New York.

All terms used in this Security and not defined herein shall have the meanings assigned to them in the Indenture.

The words “execution,” “signed,” “signature,” “delivery,” and words of like import in or relating to this Security or any document to be signed in connection with this Security shall be deemed to include electronic signatures, deliveries or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature, physical delivery thereof or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable law, including the federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other state laws based on the Uniform Electronic Transactions Act, and the parties hereto consent to conduct the transactions contemplated hereunder by electronic means.
