DESCRIPTION OF THE NOTES

We are offering $1,000,000,000 aggregate principal amount of our 4.550% Notes due 2029, $1,000,000,000 aggregate principal amount of our 4.800% Notes due 2033, $1,600,000,000 aggregate principal amount of our 5.350% Notes due 2053 and $1,400,000,000 aggregate principal amount of our 5.500% Notes due 2064. The Notes due 2029, the Notes due 2033, the Notes due 2053 and the Notes due 2064 will each be a separate series of securities issued under a senior indenture dated September 18, 2013, entered into among us, the guarantors and The Bank of New York Mellon, as trustee, as amended by the first supplemental indenture dated as of November 17, 2015, entered into among us, the guarantors and The Bank of New York Mellon, as trustee, and as further amended by the second supplemental indenture dated as of July 29, 2022, entered into among us, the guarantors and The Bank of New York Mellon, as trustee (as amended, the “indenture”). The notes will be our direct unsecured and unsubordinated obligations and will be fully and unconditionally guaranteed by Comcast Cable and NBCUniversal, referred to as the guarantors, as described below. The terms of the notes include those stated in the indenture and those made part of the indenture by reference to the Trust Indenture Act of 1939, as amended. The indenture provides that we will have the ability to issue securities with terms different from those of the notes. We also have the ability to “reopen” a series of these notes and issue additional notes of such series. Additional notes of such series will be consolidated with and form a single series with the notes then outstanding of such series; provided that if such additional notes are not fungible with the notes of the applicable series offered hereby for U.S. federal income tax purposes, such additional notes will have one or more separate CUSIP numbers. Copies of the indenture and the form of notes are available from us upon request.

The following, along with the additional information contained in the accompanying prospectus under “Description of Debt Securities and Guarantees,” is a summary of the material provisions of the indenture, the notes and the guarantees. Because this is a summary, it may not contain all the information that is important to you. For further information, you should read the notes and the indenture.

Basic Terms of the Notes

The notes:

Interest Payments

Interest on the notes will be computed on the basis of a 360-day year consisting of twelve 30-day months.

S-6

Interest on the notes will accrue from (i) the earlier of May 9, 2023 and the date of original issuance or (ii) from the most recent interest payment date to which interest has been paid, and will be payable semiannually on the interest payment dates described for each year.

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.

For more information on payment and transfer procedures for the notes, see “—Book-Entry System” below.

Guarantees

Our obligations, including the payment of principal, premium, if any, and interest, will be fully and unconditionally guaranteed by each of the guarantors as described in the accompanying prospectus.

The guarantees will not contain any restrictions on the ability of any guarantor to (i) pay dividends or distributions on, or redeem, purchase, acquire, or make a liquidation payment with respect to, any of that guarantor’s capital stock or (ii) make any payment of principal, interest or premium, if any, on or repay, repurchase or redeem any debt securities of that guarantor.

Optional Redemption

Prior to December 15, 2028 (one (1) month prior to the maturity date of the Notes due 2029) with respect to the Notes due 2029 (the “2029 Notes Par Call Date”), prior to February 15, 2033 (three (3) months prior to the maturity date of the Notes due 2033) with respect to the Notes due 2033 (the “2033 Notes Par Call Date”), prior to November 15, 2052 (six (6) months prior to the maturity date of the Notes due 2053) with respect to the Notes due 2053 (the “2053 Notes Par Call Date”) and prior to November 15, 2063 (six (6) months prior to the maturity date of the Notes due 2064) with respect to the Notes due 2064 (the “2064 Notes Par Call Date” and, together with the 2029 Notes Par Call Date, the 2033 Notes Par Call Date and the 2053 Notes Par Call Date, each a “Par Call Date”), we may redeem such notes at our option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of the principal amount and rounded to three decimal places) equal to the greater of:

(1)    (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming, for this purpose, that such notes mature on the applicable Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 15 basis points, in the case of the Notes due 2029, 20 basis points, in the case of the Notes due 2033, 25 basis points, in the case of the Notes due 2053, and 30 basis points, in the case of the Notes due 2064, as applicable, less (b) interest accrued to the date of redemption, and

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

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

On or after the 2029 Notes Par Call Date, in the case of the Notes due 2029, the 2033 Notes Par Call Date, in the case of the Notes due 2033, the 2053 Notes Par Call Date, in the case of the Notes due 2053, and the 2064 Notes Par Call Date, in the case of the Notes due 2064, as applicable, we may redeem such series of notes, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the notes being redeemed, plus accrued and unpaid interest thereon to the redemption date.

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

S-7

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

If on the third business day preceding the redemption date H.15 TCM is no longer published, we shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the relevant Par Call Date, as applicable. If there is no United States Treasury security maturing on the applicable Par Call Date, but there are two or more United States Treasury securities with a maturity date equally distant from the applicable Par Call Date, one with a maturity date preceding such Par Call Date, and one with a maturity date following such Par Call Date, we shall select the United States Treasury security with a maturity date preceding the applicable Par Call Date. If there are two or more United States Treasury securities maturing on the applicable Par Call Date, or two or more United States Treasury securities meeting the criteria of the preceding sentence, we shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of the principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

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

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the redemption date to each holder of the applicable series of notes to be redeemed.

In the case of a partial redemption, selection of the applicable series of notes for redemption will be made, if such series of notes are in the form of one or more global securities, in accordance with the procedures of The Depository Trust Company (or another depositary) or, if such series of notes are not in the form of one or more global securities, by lot. No notes of any series of a principal amount of $2,000 or less will be redeemed in part. If any note of a series is to be redeemed in part only, the notice of redemption that relates to such note will state the portion of the principal amount of the applicable note to be redeemed. A new note of any series in a principal amount equal to the unredeemed portion of the applicable note will be issued in the name of the holder of such note upon surrender for cancellation of such original note. For so long as any series of notes are registered in the name of The Depository Trust Company (or another depositary) or such depositary’s nominee, the redemption of such series of notes shall be done in accordance with the policies and procedures of the depositary.

S-8

Unless we default in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the applicable series of notes or portions thereof called for redemption.

No Mandatory Redemption or Sinking Fund

There will be no mandatory redemption prior to maturity or sinking fund payments for the notes.

Additional Debt

The indenture does not limit the amount of debt we may issue under the indenture or otherwise.

Book-Entry System

We will initially issue the notes in the form of one or more global notes (the “Global Notes”). The Global Notes will be deposited with, or on behalf of, The Depository Trust Company (“DTC”) and registered in the name of DTC or its nominee. Except as set forth below, the Global Notes may be transferred, in whole and not in part, only to DTC or another nominee of DTC. A holder may hold beneficial interests in the Global Notes directly through DTC if such holder has an account with DTC or indirectly through organizations which have accounts with DTC, including Euroclear and Clearstream.

Holders may hold interests in the notes outside the United States through Euroclear or Clearstream if they are participants in those systems, or indirectly through organizations which are participants in those systems.

Euroclear and Clearstream will hold interests on behalf of their participants through customers’ securities accounts in Euroclear’s and Clearstream’s names on the books of their respective depositaries which in turn will hold such positions in customers’ securities accounts in the names of the nominees of the depositaries on the books of DTC. All securities in Euroclear or Clearstream are held on a fungible basis without attribution of specific certificates to specific securities clearance accounts.

DTC

DTC has advised us as follows: DTC is a limited purpose trust company organized under the laws of the State of New York, 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 provisions of Section 17A of the Exchange Act. DTC was created to hold securities of institutions that have accounts with DTC (“participants”) and to facilitate the clearance and settlement of securities transactions among its participants in such securities through electronic book-entry changes in accounts of the participants, thereby eliminating the need for physical movement of securities certificates. DTC’s participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. Access to DTC’s book-entry system is also available to others such as banks, brokers, dealers and trust companies (collectively, the “indirect participants”) that clear through or maintain a custodial relationship with a participant, whether directly or indirectly.

We expect that pursuant to procedures established by DTC, upon the deposit of the Global Notes with DTC, DTC will credit on its book-entry registration and transfer system the principal amount of notes represented by such Global Notes to the accounts of participants. Ownership of beneficial interests in the Global Notes will be limited to participants or persons that may hold interests through participants. Ownership of beneficial interests in the Global Notes will be shown on and the transfer of those ownership interests will be effected only through, records maintained by DTC (with respect to participants’ interests), the participants and the indirect participants (with respect to the owners of beneficial interests in the Global Note other than participants). All interests in a Global Note deposited with DTC are subject to the procedures and requirements of DTC.

S-9

The laws of some jurisdictions may require that certain purchasers of securities take physical delivery of such securities in definitive form. Such limits and laws may impair the ability to transfer or pledge beneficial interests in the Global Notes.

So long as DTC (or its nominee) is the registered holder and owner of a Global Note, DTC (or such nominee) will be considered the sole legal owner and holder of the notes evidenced by such Global Note for all purposes of such notes and the indenture. Except as set forth below under “—Certificated Notes,” as an owner of a beneficial interest in a Global Note, you will not be entitled to have the notes represented by such Global Note registered in your name, will not receive or be entitled to receive physical delivery of certificated notes and will not be considered to be the owner or holder of any notes under such Global Note. We understand that under existing industry practice, in the event an owner of a beneficial interest in a Global Note desires to take any action that DTC, as the holder of such Global Note, is entitled to take, DTC would authorize the participants to take such action, and the participants would authorize beneficial owners owning through such participants to take such action or would otherwise act upon the instructions of beneficial owners owning through them.

We will make payments of principal of, premium, if any, and interest on the notes represented by the Global Notes registered in the name of and held by DTC or its nominee to DTC or its nominee, as the case may be, as the registered owner and holder of the Global Notes.

We expect that DTC (or its nominee), upon receipt of any payment of principal of, premium, if any, or interest on the Global Notes will credit the accounts of their relevant participants or account holders, as applicable, with payments in amounts proportionate to their respective beneficial interests in the principal amount of the applicable Global Note as shown on the records of DTC (or its nominee). We also expect that payments by participants or indirect participants or account holders, as applicable, to owners of beneficial interests in the Global Notes held through such participants or indirect participants or account holders will be governed by standing instructions and customary practices and will be the responsibility of such participants or indirect participants or account holders, as applicable. We will not have any responsibility or liability for any aspect of the records relating to, or payments made on account of, beneficial ownership interests in the Global Notes for any notes or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests or for any other aspect of the relationship between DTC and its participants or indirect participants, or the relationship between such participants or indirect participants, and the owners of beneficial interests in the Global Notes owning through such participants.

All amounts payable under the notes will be payable in U.S. dollars, except as may otherwise be agreed between any applicable securities clearing system and any holders. Payments will be subject in all cases to any fiscal or other laws and regulations (including any regulations of any applicable securities clearing system) applicable thereto. None of the trustee, us, the guarantors or any of our or their respective agents shall be liable to any holder of a Global Note or other person for any commissions, costs, losses or expenses in relation to or resulting from any currency conversion or rounding effected in connection therewith. Investors may be subject to foreign exchange risks that may have important economic and tax consequences to them.

Certificated Notes

Subject to certain conditions, the notes represented by the Global Notes are exchangeable for certificated notes in definitive form of like tenor in minimum denominations of $2,000 principal amount and multiples of $1,000 in excess thereof if:

(1)    DTC provides notification that it is unwilling or unable to continue as depositary for the Global Notes or DTC ceases to be a clearing agency registered under the Exchange Act and, in either case, a successor is not appointed within 90 days;

(2)    we in our discretion at any time determine not to have all the notes represented by the Global Notes; or

S-10

(3)    a default entitling the holders of the applicable notes to accelerate the maturity thereof has occurred and is continuing.

Any note that is exchangeable as above is exchangeable for certificated notes issuable in authorized denominations and registered in such names as DTC shall direct. Subject to the foregoing, a Global Note is not exchangeable, except for a Global Note of the same aggregate denomination to be registered in the name of DTC (or its nominee).

Same-Day Payment

The indenture requires payments to be made in respect of the applicable notes represented by the Global Notes (including principal, premium and interest) by wire transfer of immediately available funds to the accounts specified by the holder thereof or, if no such account is specified, by mailing a check to such holder’s registered address.

Payments (including principal, premium and interest) and transfers with respect to notes in certificated form may be executed at the office or agency maintained for such purpose within the City and State of New York (initially the office of the paying agent maintained for such purpose) or, at our option, by check mailed to the holders thereof at the respective addresses set forth in the register of holders of the applicable notes, provided that all payments (including principal, premium and interest) on notes in certificated form, for which the holders thereof have given wire transfer instructions, will be required to be made by wire transfer of immediately available funds to the accounts specified by the holders thereof. No service charge will be made for any registration of transfer, but payment of a sum sufficient to cover any tax or governmental charge payable in connection with that registration may be required.

S-11

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES FOR NON-U.S. HOLDERS

The following are the material U.S. federal income tax consequences of ownership and disposition of the notes. This discussion only applies to notes that meet all of the following conditions:

This discussion does not describe all of the tax consequences that may be relevant to beneficial owners of notes in light of their particular circumstances or to beneficial owners of notes subject to special rules, such as:

If a partnership or other arrangement or entity classified as a partnership for U.S. federal income tax purposes holds notes, the tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. A partner of a partnership holding notes is urged to consult his, her or its tax advisor.

This summary is based on the Code, administrative pronouncements, judicial decisions and final, temporary and proposed Treasury Regulations, changes to any of which subsequent to the date of this prospectus supplement may affect the tax consequences described herein, possibly with retroactive effect. This summary does not discuss any aspect of state, local, or non-U.S. taxation, or any U.S. federal tax considerations other than income taxation, and does not discuss the potential application of the Medicare contribution tax under Section 1411 of the Code. Persons considering the purchase of notes are urged to consult their tax advisors with regard to the application of the U.S. federal tax laws to their particular situations as well as any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

As used herein, the term “Non-U.S. Holder” means a beneficial owner of a note that is, for U.S. federal income tax purposes:

S-12

“Non-U.S. Holder” does not include an individual present in the United States for 183 days or more in the taxable year of disposition or a former citizen or former resident of the United States. Such persons are urged to consult their tax advisors regarding the U.S. federal income tax consequences of the sale, exchange or other disposition of a note.

Payments on a Note

Subject to the discussions below concerning backup withholding and FATCA, payments of principal and interest on the notes by us or any paying agent to any Non-U.S. Holder will not be subject to U.S. federal withholding tax, provided that, in the case of interest not effectively connected with the conduct of a trade or business in the United States:

Interest on a note described above will not be exempt from withholding tax unless the beneficial owner of that note certifies on a properly executed Internal Revenue Service Form W-8BEN or W-8BEN-E (or successor form), as appropriate, under penalties of perjury, that it is not a U.S. person.

If a Non-U.S. Holder of a note is engaged in a trade or business in the United States, and if interest on the note is effectively connected with the conduct of such trade or business (and, if required by an applicable income tax treaty, is attributable to a U.S. permanent establishment or a fixed base of the Non-U.S. Holder), the Non-U.S. Holder will generally not be subject to the withholding discussed in the preceding paragraphs if a properly executed, applicable Form W-8 (generally an Internal Revenue Service Form W-8ECI) is provided to the applicable withholding agent. Such a Non-U.S. Holder will, however, generally be taxed on such interest in the same manner as a U.S. person, unless an applicable income tax treaty provides otherwise. These Non-U.S. Holders are urged to consult their tax advisors with respect to other U.S. tax consequences of the ownership and disposition of notes, including the possible imposition of an additional branch profits tax at a rate of 30% (or lower treaty rate).

Sale, Exchange, Redemption or Other Disposition of a Note

Subject to the discussions below concerning backup withholding and FATCA, a Non-U.S. Holder will not be subject to U.S. federal income tax on gain realized on the sale, exchange, redemption or other disposition of such note, unless the gain is effectively connected with the conduct by the holder of a trade or business in the United States (and, if required by an applicable income tax treaty, is attributable to a U.S. permanent establishment or a fixed base of the Non-U.S. Holder).

If a Non-U.S. Holder of a note is engaged in a trade or business in the United States, and if gain realized by the Non-U.S. Holder on a sale, exchange, redemption or other disposition of such note is effectively connected with the conduct of such trade or business, the Non-U.S. Holder will generally be taxed in the same manner as a U.S. person, subject to an applicable income tax treaty providing otherwise. These Non-U.S. Holders are urged to consult their tax advisors with respect to other U.S. tax consequences of the ownership and disposition of notes, including the possible imposition of an additional branch profits tax at a rate of 30% (or lower treaty rate).

Backup Withholding and Information Reporting

Information returns will be filed with the Internal Revenue Service in connection with interest payments on the notes. Unless a Non-U.S. Holder complies with certification procedures to establish that it is not a U.S.

S-13

person, information returns may be filed with the Internal Revenue Service in connection with the proceeds from a sale or other disposition (including a redemption) and the Non-U.S. Holder may be subject to U.S. backup withholding on payments on the notes or on the proceeds from a sale or other disposition of the notes. The certification procedures required to claim the exemption from withholding tax on interest described above will satisfy the certification requirements necessary to avoid backup withholding as well. Backup withholding is not an additional tax. The amount of any backup withholding from a payment to a Non-U.S. Holder will be allowed as a credit against the Non-U.S. Holder’s U.S. federal income tax liability and may entitle the Non-U.S. Holder to a refund, provided that the required information is timely furnished to the Internal Revenue Service.

FATCA

Provisions commonly referred to as “FATCA” impose withholding of 30% on payments of U.S.-source interest and, subject to the discussion of certain proposed U.S. Treasury regulations below, payments of gross proceeds of the sale, exchange, redemption, or other disposition of a note to “foreign financial institutions” (which is broadly defined for this purpose and in general includes investment vehicles) and certain other non-U.S. entities unless various U.S. information reporting and due diligence requirements (generally relating to ownership by U.S. persons of interests in or accounts with those entities) have been satisfied or an exemption applies. Withholding under FATCA will apply to the applicable payments regardless of whether the recipient is a beneficial owner or acts as an intermediary with respect to such payments. An intergovernmental agreement between the United States and the non-U.S. entity’s jurisdiction may modify these requirements. If FATCA withholding is imposed, a beneficial owner that is not a foreign financial institution generally will be entitled to a refund of any amounts withheld by filing a U.S. federal income tax return (which may entail significant administrative burden).

The U.S. Treasury Department has released proposed regulations which, if finalized in their present form, would eliminate FATCA withholding on the gross proceeds of a sale, exchange, redemption or other disposition of a note (other than amounts treated as interest). In the preamble to the proposed regulations, the U.S. Treasury Department indicated that taxpayers may rely on the proposed regulations until final regulations are issued.

Prospective investors should consult their tax advisors regarding the effects of FATCA on their investment in the notes. We will not pay additional amounts with respect to any withholding taxes imposed under FATCA.

UNDERWRITING

We intend to offer the notes through the underwriters named below. Subject to the terms and conditions contained in an underwriting agreement, we have agreed to sell to the underwriters and the underwriters severally, and not jointly, have agreed to purchase from us, the principal amount of the notes listed opposite their names below.

The underwriters have agreed to purchase all of the notes sold pursuant to the underwriting agreement if any of these notes are purchased. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the non-defaulting underwriters may be increased or the underwriting agreement may be terminated.

S-15

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

The underwriters are offering the notes, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the notes, and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of officer’s certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

It is expected that delivery of the notes will be made against payment therefor on or about May 9, 2023, which is the sixth business day following the date hereof (such settlement cycle being referred to as “T+6”). Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in two business days unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes prior to the second business day preceding the settlement date will be required, by virtue of the fact that the notes initially will settle in T+6, to specify an alternative settlement cycle at the time of any such trade to prevent failed settlement and should consult their own advisors.

Commissions and Discounts

The underwriters have advised us that they propose initially to offer the notes to the public at the public offering price on the cover page of this prospectus supplement, and to dealers at that price less a concession not in excess of 0.150%, 0.250%, 0.450% and 0.500% of the principal amount of the Notes due 2029, the Notes due 2033, the Notes due 2053 and the Notes due 2064, respectively. The underwriters may allow, and the dealers may reallow, a discount not in excess of 0.100%, 0.150%, 0.300% and 0.300% of the principal amount of the Notes due 2029, the Notes due 2033, the Notes due 2053 and the Notes due 2064, respectively, to other dealers. After the initial public offering, the public offering prices, concessions and discounts may be changed.

The expenses of the offering, not including the underwriting discount, are estimated to be $1.25 million.

New Issue of Notes

Each series of notes are a new issue of securities with no established trading market. We do not intend to apply for listing of the notes on any national securities exchange or for quotation of the notes on any automated dealer quotation system. We have been advised by the underwriters that they presently intend to make a market in the notes after completion of the offering. However, they are under no obligation to do so and may discontinue any market-making activities at any time without any notice. We cannot assure the liquidity of the trading market for the notes or that an active public market for the notes will develop. If an active public trading market for the notes does not develop, the market price and liquidity of the notes may be adversely affected.

Price Stabilization and Short Positions

In connection with the offering, the underwriters are permitted to engage in transactions that stabilize the market price of the notes. These stabilization transactions consist of bids or purchases to peg, fix or maintain the price of the notes. If the underwriters create a short position on the notes in connection with the offering, that is, if they sell more notes than are on the cover page of this prospectus supplement, the underwriters may reduce that short position by purchasing notes in the open market. Purchases of a security to stabilize the price or to reduce a short position could cause the price of the security to be higher than it might be in the absence of such purchases. The underwriters also may impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the representatives have repurchased notes sold by or for the account of such underwriter in stabilizing or short covering transactions.

S-16

Neither we nor any of the underwriters makes 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 makes any representation that the underwriters will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

Other Relationships

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, principal investment, hedging, financing and brokerage activities for which they currently and may in the future receive customary fees and commissions. Furthermore, certain of the underwriters and their respective affiliates may, from time to time, enter into arms-length transactions with us in the ordinary course of their business.

In the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investment and securities activities may involve our securities and instruments, including the securities that are subject to the Tender Offers and our other debt, and therefore, certain of the underwriters and/or their respective affiliates may receive proceeds from this offering through the purchase of such securities in connection with the Tender Offers and/or the repayment of our other debt. Certain of the underwriters or their affiliates are acting as dealer managers in connection with the Tender Offers, for which they will receive customary fees. In addition, certain of the underwriters or their affiliates that have a lending relationship with us routinely hedge, and certain other of those underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, such underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes offered hereby. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

BNY Mellon Capital Markets, LLC, one of the underwriters, is an affiliate of The Bank of New York Mellon, the trustee under the indenture that will govern the notes.

Any resale of the notes must be made in accordance with an exemption from, or in a transaction not subject to, the prospectus requirements of applicable securities laws.

Securities legislation in certain provinces or territories of Canada may provide a purchaser with remedies for rescission or damages if this prospectus supplement (including any amendment thereto) contains a misrepresentation, provided that the remedies for rescission or damages are exercised by the purchaser within the time limit prescribed by the securities legislation of the purchaser’s province or territory.

S-17

Pursuant to section 3A.3 of National Instrument 33-105 Underwriting Conflicts (NI 33-105), the underwriters are not required to comply with the disclosure requirements of NI 33-105 regarding underwriter conflicts of interest in connection with this offering.

European Economic Area

The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (the “EEA”). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); (ii) a customer within the meaning of Directive (EU) 2016/97 (as amended, the “Insurance Distribution Directive”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Regulation (EU) 2017/1129 (as amended, the “Prospectus Regulation”). Consequently, no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

This prospectus supplement has been prepared on the basis that any offer of notes in any member state of the EEA will be made pursuant to an exemption under the Prospectus Regulation from the requirement to publish a prospectus for offers of notes. This prospectus supplement is not a prospectus for the purposes of the Prospectus Regulation.

United Kingdom

The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the United Kingdom (the “UK”). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client, as defined in point (8) of Article 2 of Regulation (EU) No 2017/565 as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018 (as amended, “EUWA”); (ii) a customer within the meaning of the provisions of the Financial Services and Markets Act 2000 (as amended, “FSMA”) and any rules or regulations made under the FSMA to implement Directive (EU) 2016/97, where that customer would not qualify as a professional client, as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the EUWA; or (iii) not a qualified investor as defined in Article 2 of Regulation (EU) 2017/1129 as it forms part of domestic law by virtue of the EUWA (the “UK Prospectus Regulation”) . Consequently no key information document required by Regulation (EU) No 1286/2014 as it forms part of domestic law by virtue of the EUWA (the “UK PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the UK has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the UK may be unlawful under the UK PRIIPs Regulation.

This prospectus supplement has been prepared on the basis that any offer of notes in the UK will be made pursuant to an exemption under the UK Prospectus Regulation from the requirement to publish a prospectus for offers of notes. This prospectus supplement is not a prospectus for the purposes of the UK Prospectus Regulation.

CAUTION CONCERNING FORWARD-LOOKING STATEMENTS

In this prospectus and in the documents we incorporate by reference, we state our beliefs of future events and of our future financial performance. In some cases, you can identify these so-called “forward-looking statements” by words such as “may,” “will,” “should,” “expects,” “believes,” “estimates,” “potential,” or “continue,” or the negative of these words, and other comparable words.

Our businesses may be affected by, among other things, the following:

USE OF PROCEEDS

We intend to use the net proceeds from the sale of the securities for working capital and general corporate purposes. We may also invest the proceeds in certificates of deposit, U.S. government securities or certain other interest-bearing securities. If we decide to use the net proceeds from a particular offering of securities for a specific purpose, we will describe that in the related prospectus supplement.

DIVIDEND POLICY

We intend to pay quarterly dividends at an annualized rate currently of $1.08 per share, although each dividend is subject to approval by our Board of Directors. Our Board of Directors retains the right to change our dividend policy at any time.

DESCRIPTION OF DEBT SECURITIES AND GUARANTEES

Our debt securities, consisting of notes, debentures or other evidences of indebtedness, may be issued from time to time in one or more series under a senior indenture dated September 18, 2013, entered into among us, the guarantors named therein and The Bank of New York Mellon, as trustee, as amended by the first supplemental indenture dated as of November 17, 2015, entered into among us, the guarantors named therein and The Bank of New York Mellon, as trustee, and the second supplemental indenture dated as of July 29, 2022, entered into among us, the guarantors named therein and The Bank of New York Mellon, as trustee.

The senior indenture is included as an exhibit to the registration statement of which this prospectus is a part.

Because the following is only a summary of the indenture and the debt securities, it does not contain all information that you may find useful. For further information about the indenture and the debt securities, you should read the indenture. As used in this section of the prospectus and under the caption “Description of Capital Stock,” the terms “we,” “us” and “our” refer solely to Comcast Corporation and such references do not include any subsidiaries of Comcast Corporation, including the Guarantors.

General

The senior debt securities will constitute our unsecured and unsubordinated obligations. The debt securities will be fully and unconditionally guaranteed by the Guarantors, as described below. The debt securities will not be guaranteed by any of our other subsidiaries, including the Guarantors’ respective subsidiaries.

We are a holding company and conduct all of our operations through subsidiaries. Consequently, our ability to pay our obligations, including our obligation to pay interest on the debt securities, to repay the principal amount of the debt securities at maturity or upon redemption or to buy back the debt securities will depend upon our subsidiaries’ earnings and their distribution of those earnings to us and upon our subsidiaries repaying investments and advances we have made to them. Our subsidiaries are separate and distinct legal entities and, except for the Guarantors with respect to the Guarantees, have no obligation, contingent or otherwise, to pay any amounts due on the debt securities or to make funds available to us to do so. Our subsidiaries’ ability to pay dividends or make other payments or advances to us will depend upon their operating results and will be subject to applicable laws and contractual restrictions. Our indentures will not limit our subsidiaries’ ability to enter into other agreements that prohibit or restrict dividends or other payments or advances to us.

You should look in the applicable prospectus supplement for the following terms of the debt securities being offered:

7

You may present debt securities for exchange and for transfer in the manner, at the places and subject to the restrictions set forth in the debt securities and the prospectus supplement. We will provide you those services without charge, although you may have to pay any tax or other governmental charge payable in connection with any exchange or transfer, as set forth in the indenture.

Debt securities will bear interest at a fixed rate or a floating rate. Debt securities bearing no interest or interest at a rate that at the time of issuance is below the prevailing market rate may be sold at a discount below their stated principal amount. Special U.S. federal income tax considerations applicable to any such discounted debt securities or to certain debt securities issued at par which are treated as having been issued at a discount for U.S. federal income tax purposes will be described in the relevant prospectus supplement.

We may issue debt securities with the principal amount payable on any principal payment date, or the amount of interest payable on any interest payment date, to be determined by reference to one or more currency exchange rates, securities or baskets of securities, commodity prices or indices. You may receive a payment of principal on any principal payment date, or a payment of interest on any interest payment date, that is greater than or less than the amount of principal or interest otherwise payable on such dates, depending upon the value on such dates of the applicable currency, security or basket of securities, commodity or index. Information as to the methods for determining the amount of principal or interest payable on any date, the currencies, securities or baskets of securities, commodities or indices to which the amount payable on such date is linked and certain additional tax considerations will be set forth in the applicable prospectus supplement.

Certain Terms of the Senior Debt Securities

Guarantees

Our obligations under the senior debt securities, including the payment of principal, premium, if any, and interest, will be fully and unconditionally guaranteed by each of the Guarantors. The Guarantees will rank equally with all other general unsecured and unsubordinated obligations of the Guarantors.

The Guarantees will not contain any restrictions on the ability of any Guarantor to:

Certain Covenants

We and the Guarantors have agreed to some restrictions on our activities for the benefit of holders of all series of senior debt securities issued under the senior indenture. The restrictive covenants summarized below

11

will apply, unless the covenants are waived or amended, so long as any of the senior debt securities are outstanding.

The senior indenture does not contain any financial covenants other than those summarized below and does not restrict us or our subsidiaries from paying dividends or incurring additional debt. In addition, the senior indenture will not protect holders of notes issued under it in the event of a highly leveraged transaction or a change in control.

Limitation on Liens Securing Indebtedness.

With respect to the senior debt securities of each series, each Obligor will covenant under the senior indenture not to create or incur any Lien on any of its Properties, whether owned at the time the senior indenture is executed or acquired afterward, in order to secure any of its Indebtedness, without effectively providing that the senior debt securities of such series shall be equally and ratably secured until such time as such Indebtedness is no longer secured by such Lien, except:

Notwithstanding the restrictions above, any Obligor may, without securing the senior debt securities of any series, create or incur Liens which would otherwise be subject to the restrictions set forth above, if after giving effect to those Liens, the Obligor’s Aggregate Debt together with the Aggregate Debt of each other Obligor does not exceed the greater of (i) 15% of Comcast’s Consolidated Net Worth calculated as of the date of the creation or incurrence of the Lien and (ii) 15% of Comcast’s Consolidated Net Worth calculated as of the date of initial issuance of the senior debt securities of such series; provided that Liens created or incurred pursuant to the terms described in this paragraph may be extended, renewed or replaced so long as the amount of Indebtedness secured by such Liens is not increased (other than by the amount equal to any costs and expenses (including any premiums, fees or penalties) incurred in connection therewith) and such refinancing Indebtedness, if then outstanding, is included in subsequent calculations of Aggregate Debt of such Obligor.

Limitation on Sale and Lease-Back Transactions.

With respect to the senior debt securities of each series, each Obligor will covenant under the senior indenture not to enter into any sale and lease-back transaction for the sale and leasing back of any Property, whether owned at the time the senior indenture is executed or acquired afterward, unless:

12

Notwithstanding the previous paragraph (including the bulleted list), any Obligor may enter into any sale and lease-back transaction which would otherwise be subject to the foregoing restrictions with respect to the senior debt securities of any series if after giving effect thereto and at the time of determination, its Aggregate Debt together with the Aggregate Debt of all other Obligors does not exceed the greater of (i) 15% of Comcast’s Consolidated Net Worth calculated as of the closing date of the sale and lease-back transaction and (ii) 15% of Comcast’s Consolidated Net Worth calculated as of the date of initial issuance of the senior debt securities of such series.

Consolidation, Merger and Sale of Assets.

We will not consolidate or combine with or merge with or into or, directly or indirectly, sell, assign, convey, lease, transfer or otherwise dispose of all or substantially all of our assets to any Person or Persons (other than a transfer or other disposition of assets to any of our wholly owned Subsidiaries), in a single transaction or through a series of transactions, unless:

The restrictions in the third bullet above shall not be applicable to:

If any consolidation or merger or any sale, assignment, conveyance, lease, transfer or other disposition of all or substantially all of our assets occurs in accordance with the indenture, the successor person will succeed to, and be substituted for us, and may exercise every right and power of ours under the indenture with the same

13

effect as if such successor person had been named in our place in the indenture. We will (except in the case of a lease) be discharged from all obligations and covenants under the indenture and any debt securities issued thereunder (including the senior debt securities).

Existence.

Except as permitted under “—Consolidation, Merger and Sale of Assets,” the indenture requires us to do or cause to be done all things necessary to preserve and keep in full force and effect our existence, rights and franchises; provided, however, that we shall not be required to preserve any right or franchise if we determine that its preservation is no longer desirable in the conduct of business.

Information.

We will furnish to the trustee any document or report we are required to file with the SEC pursuant to Section 13 or Section 15(d) of the Exchange Act within 15 days after such document or report is filed with the SEC; provided that in each case the delivery of materials to the Trustee by electronic means or filing documents pursuant to the SEC’s “EDGAR” system (or any successor electronic filing system) shall be deemed to constitute “filing” with the trustee for purposes of this covenant. Delivery of the reports, information and documents required by this section to be delivered to the trustee is for informational purposes only and the trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein.

Events of Default

Each of the following will constitute an event of default in the senior indenture with respect to the senior debt securities of any series:

(a) default in paying interest on the senior debt securities of such series when it becomes due and the default continues for a period of 30 days or more;

(b) default in paying principal on the senior debt securities of such series when due;

(c) default by any Obligor in the performance, or breach, of any covenant in the senior indenture (other than defaults specified in clause (a) or (b) above) and the default or breach continues for a period of 90 days or more after we receive written notice from the trustee or we and the trustee receive notice from the holders of at least 25% in aggregate principal amount of the senior debt securities of all affected series and the debt securities of all other affected series outstanding under the senior indenture (voting together as a single class);

(d) certain events of bankruptcy, insolvency, reorganization, administration or similar proceedings with respect to us or any Obligor have occurred; or

(e) any Guarantee shall not be (or shall be claimed by the relevant Guarantor not to be) in full force and effect.

If an event of default (other than an event of default specified in clause (d) above) under the senior indenture occurs and is continuing, then the trustee may and, at the direction of the holders of at least 25% in aggregate principal amount of the senior debt securities of all affected series and the debt securities of all other affected series outstanding under the senior indenture (voting together as a single class), will by written notice, require us to repay immediately the entire principal amount of the outstanding debt securities of each affected series, together with all accrued and unpaid interest.

If an event of default under the senior indenture specified in clause (d) occurs and is continuing, then the entire principal amount of the outstanding senior debt securities will automatically become due immediately and payable without any declaration or other act on the part of the trustee or any holder.

14

After a declaration of acceleration or any automatic acceleration under clause (d) described above, the holders of a majority in principal amount of the outstanding senior debt securities of any series (each such series voting as a separate class) may rescind this accelerated payment requirement with respect to the senior debt securities of such series if all existing events of default with respect to the senior debt securities of such series, except for nonpayment of the principal and interest on the senior debt securities of such series that have become due solely as a result of the accelerated payment requirement, have been cured or waived and if the rescission of acceleration would not conflict with any judgment or decree and if all sums paid or advanced by the trustee under the senior indenture and the reasonable compensation, expenses, disbursements and advances of the trustee and its agents and counsel have been paid.

The holders of a majority in principal amount of the senior debt securities of all affected series and the debt securities of all other affected series outstanding under the senior indenture (voting together as a single class) may, by written notice to us and the trustee, also waive past defaults, except a default in paying principal or interest on any outstanding senior debt security of such series, or in respect of a covenant or a provision that cannot be modified or amended without the consent of all affected holders of the senior debt securities of such series.

The holders of at least 25% in aggregate principal amount of the senior debt securities of all affected series and the debt securities of all other affected series outstanding under the senior indenture (voting together as a single class) may seek to institute a proceeding only after they have made written request, and offered indemnity reasonably satisfactory to the trustee, to the trustee to institute a proceeding and the trustee has failed to do so within 60 days after it received this request and offer of indemnity. In addition, within this 60-day period the trustee must not have received directions inconsistent with this written request by holders of a majority in principal amount of the senior debt securities of all affected series and the debt securities of all other affected series then outstanding. These limitations do not apply, however, to a suit instituted by a holder of the senior debt securities of any affected series for the enforcement of the payment of principal or interest on or after the due dates for such payment.

During the existence of an event of default of which a responsible officer of the trustee has actual knowledge or has received written notice from us or any holder of the senior debt securities, the trustee is required to exercise the rights and powers vested in it under the senior indenture, and use the same degree of care and skill in its exercise, as a prudent person would under the circumstances in the conduct of that person’s own affairs. If an event of default has occurred and is continuing, the trustee is not under any obligation to exercise any of its rights or powers at the request or direction of any of the holders unless the holders have offered to the trustee security or indemnity reasonably satisfactory to the trustee. Subject to certain provisions, the holders of a majority in aggregate principal amount of the senior debt securities of all affected series and the debt securities of all other affected series outstanding under the senior indenture (voting together as a single class) have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust, or power conferred on the trustee.

The trustee will, within 90 days after any default occurs with respect to the senior debt securities of any series, give notice of the default to the holders of the senior debt securities of such series, unless the default was already cured or waived. Unless there is a default in paying principal or interest when due, the trustee can withhold giving notice to the holders if it determines in good faith that the withholding of notice is in the interest of the holders.

We are required to furnish to the trustee an annual statement as to compliance with all conditions and covenants under the senior indenture within 120 days of the end of each fiscal year.

15

Discharge and Defeasance

We may terminate our obligations and the obligations of the Guarantors under the indenture with respect to the senior debt securities of any series and the Guarantees of such series of senior debt securities, when:

We may elect to have our obligations under the indenture discharged with respect to the senior debt securities of any series and the obligations of the Guarantors discharged with respect to the Guarantees of such senior debt securities (“legal defeasance”). Legal defeasance means that we will be deemed to have paid and discharged the entire indebtedness represented by the senior debt securities of a series, except for:

In addition, we may elect to have our and the Guarantors’ obligations released with respect to certain covenants in the indenture (“covenant defeasance”). In the event covenant defeasance occurs, certain events, not including nonpayment, bankruptcy and insolvency events, described under “—Events of Default” will no longer constitute an event of default for that series.

In order to exercise either legal defeasance or covenant defeasance with respect to outstanding senior debt securities and Guarantees of any series:

16

in each case sufficient without reinvestment, in the written opinion of a nationally recognized firm of independent public accountants, to pay and discharge, and which shall be applied by the trustee to pay and discharge, all of the principal and interest due on or prior to maturity or if we have made irrevocable arrangements satisfactory to the trustee for the giving of notice of redemption by the trustee in our name and at our expense, due on or prior to the redemption date;

Modification and Waiver

We, the Guarantors and the trustee may amend or modify the senior indenture or the senior debt securities of any series without notice to or the consent of any holder in order to:

17

Other amendments and modifications of the senior indenture or the senior debt securities of any series may be made with the consent of the holders of not less than a majority in aggregate principal amount of the senior debt securities of all series and the debt securities of all other series outstanding under the indenture that are affected by the amendment or modification (voting together as a single class), and our compliance with any provision of the indenture with respect to the debt securities of any series issued under the indenture (including the senior debt securities) may be waived by written notice to us and the trustee by the holders of a majority in aggregate principal amount of the debt securities of all series outstanding under the indenture that are affected by the waiver (voting together as a single class). However, no modification or amendment may, without the consent of the holder of such affected senior debt security:

An amendment, supplemental indenture or waiver which changes, eliminates or waives any covenant or other provision of the indenture which has expressly been included solely for the benefit of one or more particular series of debt securities, or which modifies the rights of the holders of debt securities of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under the indenture of the holders of debt securities of any other series.

No Personal Liability of Incorporators, Stockholders, Officers, Directors, or Employees

The senior indenture provides that no recourse shall be had under or upon any obligation, covenant or agreement contained in the senior indenture, the Guarantees or in any senior debt security, or because of any indebtedness evidenced thereby, shall be had against any incorporator, as such, or against any past, present or

18

future stockholder, employee, officer or director, as such, of us, any Guarantor, or of any of their respective successors, either directly or through us, any Guarantor, or of any of their respective successors, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance of the senior debt securities by the holders thereof and as part of the consideration for the issue of the senior debt securities.

Concerning the Trustee

Except during the continuance of an event of default, the trustee need perform only those duties that are specifically set forth in the senior indenture and no others, and no implied covenants or obligations will be read into the senior indenture against the trustee. In case an event of default of which a certain officers of the trustee shall have actual knowledge or shall have received written notice from us or any holder of our senior debt securities of any series has occurred and is continuing, the trustee shall exercise those rights and powers vested in it by the senior indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs.

Governing Law

The senior indenture, including any Guarantee, and each senior debt security is governed by and construed in accordance with the laws of the State of New York.

The Trustee

We may have normal banking relationships with the trustee under the senior indenture in the ordinary course of business.

Convertible Debt Securities

The terms, if any, on which debt securities being offered may be exchanged for or converted into other debt securities or shares of preferred stock, Class A common stock or other securities or rights of ours (including rights to receive payments in cash or securities based on the value, rate or price of one or more specified commodities, currencies or indices) or securities of other issuers or any combination of the foregoing will be set forth in the prospectus supplement for such debt securities being offered.

19

GLOBAL SECURITIES

We may issue the debt securities, warrants, purchase contracts and units of any series in the form of one or more fully registered global securities that will be deposited with a depositary or with a nominee for a depositary identified in the prospectus supplement relating to such series and registered in the name of the depositary or its nominee. In that case, one or more global securities will be issued in a denomination or aggregate denominations equal to the portion of the aggregate principal or face amount of outstanding registered securities of the series to be represented by such global securities. Unless and until the depositary exchanges a global security in whole for securities in definitive registered form, the global security may not be transferred except as a whole by the depositary to a nominee of the depositary or by a nominee of the depositary to the depositary or another nominee of the depositary or by the depositary or any of its nominees to a successor of the depositary or a nominee of such successor.

The specific terms of the depositary arrangement with respect to any portion of a series of securities to be represented by a global security will be described in the prospectus supplement relating to such series. We anticipate that the following provisions will apply to all depositary arrangements.

Ownership of beneficial interests in a global security will be limited to persons that have accounts with the depositary for such global security known as “participants” or persons that may hold interests through such participants. Upon the issuance of a global security, the depositary for such global security will credit, on its book-entry registration and transfer system, the participants’ accounts with the respective principal or face amounts of the securities represented by such global security beneficially owned by such participants. The accounts to be credited shall be designated by any dealers, underwriters or agents participating in the distribution of such securities. Ownership of beneficial interests in such global security will be shown on, and the transfer of such ownership interests will be effected only through, records maintained by the depositary for such global security (with respect to interests of participants) and on the records of participants (with respect to interests of persons holding through participants). The laws of some states may require that certain purchasers of securities take physical delivery of such securities in definitive form. Such limits and such laws may impair the ability to own, transfer or pledge beneficial interests in global securities.

So long as the depositary for a global security, or its nominee, is the registered owner of such global security, such depositary or such nominee, as the case may be, will be considered the sole owner or holder of the securities represented by such global security for all purposes under the applicable indenture, warrant agreement, purchase contract or unit agreement. Except as set forth below, owners of beneficial interests in a global security will not be entitled to have the securities represented by such global security registered in their names, will not receive or be entitled to receive physical delivery of such securities in definitive form and will not be considered the owners or holders thereof under the applicable indenture, warrant agreement, purchase contract or unit agreement. Accordingly, each person owning a beneficial interest in a global security must rely on the procedures of the depositary for such global security and, if such person is not a participant, on the procedures of the participant through which such person owns its interest, to exercise any rights of a holder under the applicable indenture, warrant agreement, purchase contract or unit agreement. We understand that under existing industry practices, if we request any action of holders or if an owner of a beneficial interest in a global security desires to give or take any action which a holder is entitled to give or take under the applicable indenture, warrant agreement, purchase contract or unit agreement, the depositary for such global security would authorize the participants holding the relevant beneficial interests to give or take such action, and such participants would authorize beneficial owners owning through such participants to give or take such action or would otherwise act upon the instructions of beneficial owners holding through them.

Principal, premium, if any, and interest payments on debt securities, and any payments to holders with respect to warrants, purchase contracts or units represented by a global security registered in the name of a depositary or its nominee will be made to such depositary or its nominee, as the case may be, as the registered owner of such global security. None of us, the trustees, the warrant agents, the unit agents or any of our other

20

agents, agent of the trustees or agent of the warrant agents or unit agents will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in such global security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

We expect that the depositary for any securities represented by a global security, upon receipt of any payment of principal, premium, interest or other distribution of underlying securities or commodities to holders in respect of such global security, will immediately credit participants’ accounts in amounts proportionate to their respective beneficial interests in such global security as shown on the records of such depositary. We also expect that payments by participants to owners of beneficial interests in such global security held through such participants will be governed by standing customer instructions and customary practices, as is now the case with the securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of such participants.

If the depositary for any securities represented by a global security is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Exchange Act, and we do not appoint a successor depositary registered as a clearing agency under the Exchange Act within 90 days, we will issue such securities in definitive form in exchange for such global security. In addition, we may at any time and in our sole discretion determine not to have any of the securities of a series represented by one or more global securities and, in such event, will issue securities of such series in definitive form in exchange for all of the global security or securities representing such securities. Any securities issued in definitive form in exchange for a global security will be registered in such name or names as the depositary shall instruct the relevant trustee, warrant agent or other relevant agent of ours. We expect that such instructions will be based upon directions received by the depositary from participants with respect to ownership of beneficial interests in such global security.

As a general matter, on all matters submitted for a vote to holders of all classes of our voting stock, holders of our Class A common stock in the aggregate hold 66 2/3% of the aggregate voting power of our capital stock, and holders of our Class B common stock in the aggregate hold a non-dilutable 33 1/3% of the combined voting power of our capital stock. This nondilutable voting power is subject to proportional decrease to the extent the number of shares of Class B common stock is reduced below 9,444,375, subject to adjustment in specified situations. Stock dividends payable on the Class B common stock in the form of Class B common stock do not decrease the nondilutable voting power of the Class B common stock.

Approval Rights

Except as required by law, holders of Class A common stock have no specific approval rights over any corporate actions. Holders of our Class B common stock have an approval right over (1) any merger of us with another company or any other transaction, in each case that requires our shareholders’ approval under applicable law, or any other transaction that would result in any person or group owning shares representing in excess of 10% of the aggregate voting power of the resulting or surviving corporation, or any issuance of securities (other than pursuant to director or officer stock option or purchase plans) requiring our shareholders’ approval under the rules and regulations of any stock exchange or quotation system; (2) any issuance of our Class B common stock or any securities exercisable or exchangeable for or convertible into our Class B common stock; and (3) articles

22

of incorporation or by-law amendments (such as an amendment to the articles of incorporation to opt in to any of the Pennsylvania antitakeover statutes) and other actions (such as the adoption, amendment or redemption of a shareholder rights plan) that limit the rights of holders of our Class B common stock or any subsequent transferee of our Class B common stock to transfer, vote or otherwise exercise rights with respect to our capital stock.

Principal Shareholder

Brian L. Roberts, our Chairman, Chief Executive Officer and President, beneficially owns all outstanding shares of our Class B common stock, which has a nondilutable 33 1/3% of the combined voting power of our stock and which also has separate approval rights over certain material transactions, as described above under “—Approval Rights.” Accordingly, Mr. Roberts has considerable influence over our operations and has the ability to transfer potential effective control by selling the Class B common stock. The Class B common stock is convertible on a share-for-share basis into Class A common stock. As of June 30, 2022, if Mr. Roberts were to convert the Class B common stock he beneficially owns into Class A common stock, Mr. Roberts would beneficially own approximately 1% of the Class A common stock that would be outstanding after the conversion.

Conversion of Class B Common Stock

The Class B common stock is convertible share for share into Class A common stock, subject to certain restrictions.

Preference on Liquidation

In the event of our liquidation, dissolution or winding up, either voluntary or involuntary, the holders of Class A common stock and Class B common stock are entitled to receive, subject to any liquidation preference of any preferred stock then outstanding, our remaining assets, if any, in proportion to the number of shares held by them without regard to class.

Mergers, Consolidations, Etc.

Our articles of incorporation provide that if in a transaction such as a merger, consolidation, share exchange or recapitalization, holders of each class of our common stock outstanding do not receive the same consideration for each of their shares of our common stock (i.e., the same amount of cash or the same number of shares of each class of stock issued in the transaction in proportion to the number of shares of our common stock held by them, respectively, without regard to class), holders of each such class of our common stock will receive “mirror” securities (i.e., shares of a class of stock having substantially equivalent rights as the applicable class of our common stock).

Miscellaneous

The holders of Class A common stock and Class B common stock do not have any preemptive rights. All shares of Class A common stock and Class B common stock presently outstanding are, and all shares of the Class A common stock offered hereby, or issuable upon conversion, exchange or exercise of securities offered hereby, will, when issued, be, fully paid and nonassessable. We have been advised that the Class A common stock is exempt from existing Pennsylvania personal property tax.

The transfer agent and registrar for our Class A common stock is Equiniti Trust Company D/B/A EQ Shareowner Services, P.O. Box 64854, St. Paul, Minnesota 55164-0854. Its telephone number is (888) 883-8903.

PLAN OF DISTRIBUTION

We or selling security holders may sell the securities being offered hereby in four ways:

If any securities are sold pursuant to this prospectus by any person other than us, we will disclose in a prospectus supplement required information with respect to each security holder, which may include its name, the nature of any relationship it has had with us or any of our affiliates during the three years preceding such offering and the amount of securities of the class it owns both before and after the offering.

We or any selling security holder may directly solicit offers to purchase securities, or we or any selling security holder may designate agents to solicit such offers. We will, in the prospectus supplement relating to such offering, name any agent that could be viewed as an underwriter under the Securities Act of 1933, as amended, (hereinafter, the “Securities Act”) and describe any commissions we or any selling security holder must pay. Any such agent will be acting on a best efforts basis for the period of its appointment or, if indicated in the applicable prospectus supplement, on a firm commitment basis. Agents, dealers and underwriters may be customers of, engage in transactions with, or perform services for us in the ordinary course of business.

If any underwriters are utilized in the sale of the securities in respect of which this prospectus is delivered, we will enter into an underwriting agreement with them at the time of sale to them, and we will set forth in the prospectus supplement relating to such offering their names and the terms of any agreement with them.

If a dealer is utilized in the sale of the securities in respect of which the prospectus is delivered, we and any selling security holders will sell such securities to the dealer, as principal. The dealer may then resell such securities to the public at varying prices to be determined by such dealer at the time of resale.

Remarketing firms, agents, underwriters and dealers may be entitled under agreements which they may enter into with us or any selling security holder to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, and may be customers of, engage in transactions with or perform services for us in the ordinary course of business.

In order to facilitate the offering of the securities, any underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the securities or any other securities the prices of which may be used to determine payments on such securities. Specifically, any underwriters may overallot in connection with the offering, creating a short position for their own accounts. In addition, to cover overallotments or to stabilize the price of the securities or of any such other securities, the underwriters may bid for, and purchase, the securities or any such other securities in the open market. Finally, in any offering of the securities through a syndicate of underwriters, the underwriting syndicate may reclaim selling concessions allowed to an underwriter or a dealer for distributing the securities in the offering if the syndicate repurchases previously distributed securities in transactions to cover syndicate short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the securities above independent market levels. Any such underwriters are not required to engage in these activities and may end any of these activities at any time.

Any underwriter, agent or dealer utilized in the initial offering of securities will not confirm sales to accounts over which it exercises discretionary authority without the prior specific written approval of its customer.
