COMCAST CORPORATION

3.250% Notes due 2032

1. Interest.

COMCAST CORPORATION, a Pennsylvania corporation (the “Issuer”), promises to pay interest on the principal amount of this Security at the rate per annum shown above. Cash interest on the Securities will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from September 26, 2024. The Issuer will pay interest annually in arrears on the Interest Payment Date, commencing September 26, 2025.

Interest on the Securities will be computed on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date to which interest was paid on the Securities (or September 26, 2024 if no interest has been paid on the Securities), to but excluding the next scheduled Interest Payment Date. This payment convention is referred to as ACTUAL/ACTUAL (ICMA) as defined in the rulebook of the International Capital Market Association.

If any Interest Payment Date, maturity date or redemption date falls on a day that is not a Business Day, the payment will be made on the next Business Day with the same force and effect as if made on the relevant Interest Payment Date, maturity date or redemption date, and no interest will accrue in respect of the delay.

The term “Business Day” means any day other than a Saturday or Sunday (i) which is not a day on which banking institutions in The City of New York or London are authorized or obligated by law, regulation or executive order to close and (ii) on which the Trans-European Automated Real-Time Gross Settlement Express Transfer System (the T2 system) or any successor thereto is open.

The Issuer shall pay interest on overdue principal from time to time on demand at the rate borne by the Securities and on overdue installments of interest (without regard to any applicable grace periods) to the extent lawful.

2. Issuance in Euro.

Principal, premium, if any, and interest payments will be payable in Euro. If Euro is unavailable to the Issuer due to the imposition of exchange controls or other circumstances beyond the Issuer’s control, then all payments will be made in U.S. dollars until Euro is again available to the Issuer. The amount payable on any date in Euro will be converted into U.S. dollars at the Market Exchange Rate (as defined below) or, if such Market Exchange Rate is not then available, on the basis of the most recently available market exchange rate for Euro. Any payment so made in U.S. dollars will not constitute an event of default under the Indenture. Neither the Trustee nor the Paying Agent will be responsible for obtaining exchange rates, effecting currency conversions or otherwise handling re-denominations.

The term “Market Exchange Rate” means the noon buying rate in The City of New York for cable transfers of Euro as certified for customs purposes (or, if not so certified, as otherwise determined) by the Federal Reserve Bank of New York.

3. Method of Payment.

The Issuer shall pay interest on the Securities (except defaulted interest) to the persons who are the registered Holders at the close of business on the Interest Record Date immediately preceding the Interest Payment Date notwithstanding any transfer or exchange of such Security subsequent to such Interest Record Date and prior to such Interest Payment Date. Holders must surrender Securities to The Bank of New York Mellon (the “Trustee”) to collect principal payments.

The payments of interest, and any portion of the principal (other than interest payable at maturity or on any redemption or repayment date or the final payment of principal) shall be made by the Paying Agent, upon receipt from the Issuer of immediately available funds by 10:00 a.m., London time one Business Day prior to the payment due date (or such other time as may be agreed to between the Issuer and the Paying Agent), directly to a Holder (by Federal funds wire transfer or otherwise) if the Holder has delivered written instructions to the Paying Agent 10 days prior to such payment date requesting that such payment will be so made and designating the bank account to which such payments shall be so made and in the case of payments of principal surrenders the same to the Trustee in exchange for a Security or Securities aggregating the same principal amount as the unredeemed principal amount of the Securities surrendered.

Notwithstanding anything to the contrary herein, the Securities are subject to all such terms, and Holders of Securities are referred to the Indenture and the TIA for a statement of them. To the extent the terms of the Indenture and this Security are inconsistent, the terms of the Indenture shall govern. This note is a “Security” and the notes are “Securities” under the Indenture.

The term “comparable government bond rate” means the yield to maturity, expressed as a percentage (rounded to three decimal places, with 0.0005 being rounded upwards), on the third Business Day prior to the date fixed for redemption, of the applicable comparable government bond on the basis of the middle market price of such comparable government bond prevailing at 11:00 a.m. (London time) on such business day as determined by an independent investment banker selected by the Issuer.

5.250% Notes due 2040

1. Interest.

COMCAST CORPORATION, a Pennsylvania corporation (the “Issuer”), promises to pay interest on the principal amount of this Security at the rate per annum shown above. Cash interest on the Securities will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from September 26, 2024. The Issuer will pay interest annually in arrears on the Interest Payment Date, commencing September 26, 2025.

Interest on the Securities will be computed on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date to which interest was paid on the Securities (or September 26, 2024 if no interest has been paid on the Securities), to but excluding the next scheduled Interest Payment Date. This payment convention is referred to as ACTUAL/ACTUAL (ICMA) as defined in the rulebook of the International Capital Market Association.

If any Interest Payment Date, maturity date or redemption date falls on a day that is not a Business Day, the payment will be made on the next Business Day with the same force and effect as if made on the relevant Interest Payment Date, maturity date or redemption date, and no interest will accrue in respect of the delay.

The term “Business Day” means any day other than a Saturday or Sunday (i) which is not a day on which banking institutions in The City of New York or London are authorized or obligated by law, regulation or executive order to close and (ii) on which the Trans-European Automated Real-Time Gross Settlement Express Transfer System (the T2 system) or any successor thereto is open.

The Issuer shall pay interest on overdue principal from time to time on demand at the rate borne by the Securities and on overdue installments of interest (without regard to any applicable grace periods) to the extent lawful.

2. Issuance in Sterling.

Principal, premium, if any, and interest payments will be payable in Sterling. If Sterling is unavailable to the Issuer due to the imposition of exchange controls or other circumstances beyond the Issuer’s control, then all payments will be made in U.S. dollars until Sterling is again available to the Issuer. The amount payable on any date in Sterling will be converted into U.S. dollars at the Market Exchange Rate (as defined below) or, if such Market Exchange Rate is not then available, on the basis of the most recently available market exchange rate for Sterling. Any payment so made in U.S. dollars will not constitute an event of default under the Indenture. Neither the Trustee nor the Paying Agent will be responsible for obtaining exchange rates, effecting currency conversions or otherwise handling re-denominations.

The term “Market Exchange Rate” means the noon buying rate in The City of New York for cable transfers of Sterling as certified for customs purposes (or, if not so certified, as otherwise determined) by the Federal Reserve Bank of New York.

3. Method of Payment.

The Issuer shall pay interest on the Securities (except defaulted interest) to the persons who are the registered Holders at the close of business on the Interest Record Date immediately preceding the Interest Payment Date notwithstanding any transfer or exchange of such Security subsequent to such Interest Record Date and prior to such Interest Payment Date. Holders must surrender Securities to The Bank of New York Mellon (the “Trustee”) to collect principal payments.

The payments of interest, and any portion of the principal (other than interest payable at maturity or on any redemption or repayment date or the final payment of principal) shall be made by the Paying Agent, upon receipt from the Issuer of immediately available funds by 10:00 a.m., London time one Business Day prior to the payment due date (or such other time as may be agreed to between the Issuer and the Paying Agent), directly to a Holder (by Federal funds wire transfer or otherwise) if the Holder has delivered written instructions to the Paying Agent 10 days prior to such payment date requesting that such payment will be so made and designating the bank account to which such payments shall be so made and in the case of payments of principal surrenders the same to the Trustee in exchange for a Security or Securities aggregating the same principal amount as the unredeemed principal amount of the Securities surrendered.

Notwithstanding anything to the contrary herein, the Securities are subject to all such terms, and Holders of Securities are referred to the Indenture and the TIA for a statement of them. To the extent the terms of the Indenture and this Security are inconsistent, the terms of the Indenture shall govern. This note is a “Security” and the notes are “Securities” under the Indenture.

In addition, we have assumed that the Indenture and the Securities (collectively, the “Documents”) are valid, binding and enforceable agreements of each party thereto (other than as expressly covered above in respect of the Company and the Guarantors). We have also assumed that the execution, delivery and performance by each party to each Document to which it is a party (a) are within their corporate or limited liability company powers, as applicable, (b) do not contravene, or constitute a default under, the certificate of incorporation or bylaws or other constitutive documents of the Company or any Guarantor, (c) require no action by or in respect of, or filing with, any governmental body, agency or official and (d) do not contravene, or constitute a default under, any provision of applicable law or regulation or any judgment, injunction, order or decree or any agreement or other instrument binding upon the Company or any Guarantor, provided that we make no such assumption to the extent that we have specifically opined as to such matters with respect to the Company and each Guarantor.

We are members of the Bar of the State of New York and the foregoing opinions are limited to the laws of the State of New York and the Limited Liability Company Act of the State of Delaware, except that we express no opinion as to any law, rule or regulation that is applicable to the Company or the Guarantors, the Documents or such transactions solely because such law, rule or regulation is part of a regulatory regime applicable to any party to any of the Documents or any of its affiliates due to the specific assets or business of such party or such affiliate. Insofar as the foregoing opinions involve matters governed by the laws of the Commonwealth of Pennsylvania, we have relied, without independent inquiry or investigation, on the opinions of the Senior Deputy General Counsel of the Company to be filed as an exhibit to a report on Form 8-K to be filed by the Company on the date hereof.
