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. You should be aware that those statements are only our predictions. In evaluating those statements, you should specifically consider various factors, including the risks and uncertainties listed in “Item 1A—Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2014 incorporated herein by reference. Actual events or our actual results may differ materially from any of our forward-looking statements. We undertake no obligation to update any forward-looking statements.

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 annual rate currently of $1.00 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.

RATIOS OF EARNINGS TO FIXED CHARGES AND OF EARNINGS TO COMBINED FIXED CHARGES AND PREFERRED DIVIDENDS

Our ratio of earnings to fixed charges and our ratio of earnings to combined fixed charges and preferred dividends were as follows for the respective periods indicated:

We have no issued or outstanding Comcast preferred stock and, as a result, the ratio of earnings to fixed charges is the same as the ratio of earnings to combined fixed charges and preferred dividends. For purposes of calculating the ratios, earnings is the amount resulting from (1) adding (a) pretax income from continuing operations before adjustment for noncontrolling interests in consolidated subsidiaries or income or loss from equity investees, (b) fixed charges, (c) amortization of capitalized interest, (d) distributed income of equity investees and (e) our share of pretax losses of equity investees for which charges arising from guarantees are included in fixed charges and (2) subtracting (i) interest capitalized, (ii) preference security dividend requirements of consolidated subsidiaries and (iii) the noncontrolling interest in pretax income of subsidiaries that have not incurred fixed charges. Fixed charges is the sum of (w) interest expensed and capitalized, (x) amortized premiums, discounts and capitalized expenses related to indebtedness, (y) an estimate of the interest within rental expense and (z) preference security dividend requirements of our consolidated subsidiaries. Preference security dividend requirements are the amount of pretax earnings required to pay the dividends on outstanding preference securities. Interest associated with our uncertain tax positions is a component of income tax expense.

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 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:

Table of Contents

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:

Table of Contents

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 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:

11

Table of Contents

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, and may exercise every right and power of ours under the indenture with the same effect

12

Table of Contents

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.

13

Table of Contents

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.

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:

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:

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 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.

Gerald L. Hassell, one of our directors, is the Chairman and Chief Executive Officer and a director of the trustee.

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 Class A Special 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.

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

19

Table of Contents

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.

DESCRIPTION OF CAPITAL STOCK

In this section, references to the “Company,” “we,” “us” and “our” refer only to Comcast Corporation and not any of its subsidiaries. The statements made under this caption include summaries of certain provisions contained in our articles of incorporation and by-laws. These statements do not purport to be complete and are qualified in their entirety by reference to such articles of incorporation and by-laws.

We have three classes of common stock outstanding: Class A common stock, $0.01 par value per share; Class A Special common stock, $0.01 par value per share; and Class B common stock, $0.01 par value per share. There are currently authorized 7.5 billion shares of Class A common stock, 7.5 billion shares of Class A Special common stock, 75 million shares of Class B common stock and 20 million shares of preferred stock. Our Board of Directors may issue preferred stock, in one or more series, without par value, with full, limited, multiple, fractional, or no voting rights, and with such designations, preferences, qualifications, privileges, limitations, restrictions, options, conversion rights and other special rights as our Board of Directors shall determine.

Dividends

Subject to the preferential rights of any preferred stock then outstanding, holders of our Class A common stock, Class A Special common stock, and Class B common stock are entitled to receive, from time to time, when, as and if declared, in the discretion of our Board, such cash dividends as our Board may from time to time determine, out of such funds as are legally available therefor, in proportion to the number of shares held by them, respectively, without regard to class.

Holders of our Class A common stock, Class A Special common stock, and Class B common stock will also be entitled to receive, from time to time, when, as and if declared by our Board, such dividends of our stock or other property as our Board may determine, out of such funds as are legally available therefor. However, stock dividends on, or stock splits of, any class of common stock will not be paid or issued unless paid or issued on all classes of our common stock, in which case they will be paid or issued only in shares of that class; provided, however, that stock dividends on, or stock splits of, our Class B common stock may also be paid or issued in shares of our Class A Special common stock.

We intend to pay quarterly dividends at an annual rate currently of $1.00 per share, although each dividend is subject to approval by our Board of Directors. See “Dividend Policy” above.

Voting Rights

Except as required by law, holders of our Class A Special common stock are not entitled to vote. When holders of our Class A Special common stock are entitled to vote by applicable law, each share of our Class A Special common stock has the same number of votes as each share of our Class A common stock.

As of December 31, 2014, on all matters submitted for a vote of 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. As of December 31, 2014, our Class B common stock has a nondilutable 33  ¹ / ₃ % of the combined voting power of our common 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 or Class A Special 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 Special common stock and Class A common stock have no specific approval rights over any corporate actions. Holders of our Class B common stock have an approval right

21

Table of Contents

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) charter or by-law amendments (such as a charter amendment 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 or Class A Special common stock. As of September 30, 2015, if Mr. Roberts were to convert the Class B common stock he beneficially owns into Class A common stock, Mr. Roberts would beneficially own 15,182,592 shares of Class A common stock, which is less than 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 either the Class A common stock or the Class A Special common stock.

Preference on Liquidation

In the event of our liquidation, dissolution or winding up, either voluntary or involuntary, the holders of Class A Special common stock, 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 charter provides 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, Class A Special common stock and Class B common stock do not have any preemptive rights. All shares of Class A common stock, Class A Special common stock and Class B common stock presently outstanding are, and all shares of the Class A common stock and Class A Special 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 and Class A Special common stock are exempt from existing Pennsylvania personal property tax.

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.

Comcast Corporation

Indemnification under Pennsylvania Law and Comcast’s Charter and By-laws.

Sections 1741 through 1750 of Subchapter D, Chapter 17, of the Pennsylvania Business Corporation Law (“PBCL”) contain provisions for mandatory and discretionary indemnification of a corporation’s directors, officers and other personnel, and related matters.

Under Section 1741 of the PBCL, subject to certain limitations, a corporation has the power to indemnify directors and officers under certain prescribed circumstances against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred in connection with an action or proceeding, whether civil, criminal, administrative or investigative (other than derivative or corporate actions), to which any such officer or director is a party or is threatened to be made a party by reason of such officer or director being a representative of the corporation or serving at the request of the corporation as a representative of another domestic or foreign corporation for profit or not-for-profit, partnership, joint venture, trust or other enterprise, so long as the director or officer acted in good faith and in a manner reasonably believed to be in, or not opposed to, the best interests of the corporation and, with respect to any criminal proceeding, such officer or director had no reasonable cause to believe his conduct was unlawful.

Section 1742 of the PBCL permits indemnification in derivative and corporate actions if the director or officer acted in good faith and in a manner he reasonably believed to be in, or not opposed to, the best interests of the corporation, except in respect of any claim, issue or matter as to which the officer or director has been adjudged to be liable to the corporation unless and only to the extent that the proper court determines upon application that, despite the adjudication of liability but in view of all the circumstances of the case, the officer or director is fairly and reasonably entitled to indemnity for the expenses that the court deems proper.

Under Section 1743 of the PBCL, indemnification is mandatory to the extent that the officer or director has been successful on the merits or otherwise in defense of any action or proceeding referred to in Section 1741 or 1742 of the PBCL.

II-1

Table of Contents

Section 1744 of the PBCL provides that, unless ordered by a court, any indemnification under Section 1741 or 1742 of the PBCL shall be made by the corporation only as authorized in the specific case upon a determination that the officer or director met the applicable standard of conduct, and such determination must be made by (i) the board of directors by a majority vote of a quorum of directors not parties to the action or proceeding, (ii) if a quorum is not obtainable, or if obtainable and a majority vote of a quorum of disinterested directors so directs, by independent legal counsel in a written opinion, or (iii) by the shareholders.

Section 1745 of the PBCL provides that expenses (including attorneys’ fees) incurred by a director or officer in defending any action or proceeding referred to in Subchapter D of Chapter 17 of the PBCL may be paid by the corporation in advance of the final disposition of such action or proceeding upon receipt of an undertaking by or on behalf of such person to repay such amount if it shall ultimately be determined that he is not entitled to be indemnified by the corporation. Except as otherwise provided in the corporation’s by-laws, advancement of expenses must be authorized by the board of directors.

Section 1746 of the PBCL provides generally that the indemnification and advancement of expenses provided by Subchapter D of Chapter 17 of the PBCL shall not be deemed exclusive of any other rights to which an officer or director seeking indemnification or advancement of expenses may be entitled under any by-law, agreement, vote of shareholders or disinterested directors or otherwise, both as to action in his official capacity and as to action in another capacity while holding that office. In no event may indemnification be made in any case where the act or failure to act giving rise to the claim for indemnification is determined by a court to have constituted willful misconduct or recklessness.

Section 1747 of the PBCL grants a corporation the power to purchase and maintain insurance on behalf of any director or officer against any liability incurred by him in his capacity as officer or director, whether or not the corporation would have the power to indemnify him against that liability under Subchapter D of Chapter 17 of the PBCL.

Sections 1748 and 1749 of the PBCL extend the indemnification and advancement of expenses provisions contained in Subchapter D of Chapter 17 of the PBCL to successor corporations in fundamental changes and to officers and directors serving as fiduciaries of employee benefit plans.

Section 1750 of the PBCL provides that the indemnification and advancement of expenses provided by, or granted pursuant to, Subchapter D of Chapter 17 of the PBCL shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be a director or officer shall inure to the benefit of the heirs and personal representatives of such person.

Article Twelfth of the Comcast charter provides that no director of Comcast will be personally liable, as such, for monetary damages (other than under criminal statutes and under laws imposing such liability on directors for the payment of taxes) unless such person’s conduct constitutes self-dealing, willful misconduct or recklessness. Article Twelfth of the Comcast charter extends such protection to officers.

Article 7 of the Comcast by-laws provides that each officer and director of Comcast will be indemnified and held harmless by Comcast to the fullest extent permitted by Pennsylvania law against all expense, liability and loss (including, without limitation, attorneys’ fees, judgments, fines, taxes, penalties and amounts paid or to be paid in settlement) reasonably incurred or suffered by such officer or director in connection with any threatened, pending or completed action, suit or proceeding (including, without limitation, an action, suit or proceeding by or in the right of Comcast), whether civil, criminal, administrative or investigative (a “Proceeding”). No indemnification will be made, however, in any case where the act or failure to act giving rise to the claim for indemnification is determined by a court to have constituted willful misconduct or recklessness, or in connection with a Proceeding (or part of a Proceeding) initiated by an officer or director (except in connection with a Proceeding to enforce a right to indemnification or advancement of expenses), unless the Proceeding (or part of the Proceeding) was authorized by the Board of Directors. The right to indemnification includes the right to have the expenses incurred by such director or officer in participating in any Proceeding paid by Comcast in advance

of the final disposition of the Proceeding automatically and without any action or approval required by the Board of Directors, provided that, if Pennsylvania law requires, the payment of expenses incurred by such director or officer in advance of the final disposition of a Proceeding shall only be made upon delivery to Comcast of an undertaking, by or on behalf of the director or officer, to repay all advanced amounts without interest if it is ultimately determined that the director or officer is not entitled to be so indemnified.

Article 7 of the Comcast by-laws also provides that Comcast may purchase and maintain insurance, at its expense, for the benefit of any person on behalf of whom insurance is permitted to be purchased by Pennsylvania law against any expense, liability or loss, whether or not Comcast would have the power to indemnify such person under Pennsylvania or any other law. Comcast may also purchase and maintain insurance to insure its indemnification obligations.

The foregoing statements are subject to the detailed provisions of the PBCL and to the applicable provisions of the Comcast charter and by-laws.
