REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Plan Administrator

Comcast Corporation Retirement-Investment Plan

Philadelphia, Pennsylvania

We have audited the accompanying statements of net assets available for benefits of the Comcast Corporation Retirement-Investment Plan (the “Plan”) as of December 31, 2011 and 2010, and the related statement of changes in net assets available for benefits for the year ended December 31, 2011. These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Plan is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Plan’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2011 and 2010, and the changes in net assets available for benefits for the year ended December 31, 2011 in conformity with accounting principles generally accepted in the United States of America.

Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule of assets (held at year end) as of December 31, 2011 is presented for the purpose of additional analysis and is not a required part of the basic financial statements, but is supplementary information required by the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This schedule is the responsibility of the Plan’s management. The schedule has been subjected to the auditing procedures applied in our audit of the basic 2011 financial statements and, in our opinion, is fairly stated in all material respects when considered in relation to the basic financial statements taken as a whole.

NOTES TO FINANCIAL STATEMENTS

YEARS ENDED DECEMBER 31, 2011 and 2010

1. PLAN DESCRIPTION

General

The following description of the Comcast Corporation Retirement-Investment Plan (the “Plan”) provides only general information. Plan participants should refer to the Plan document and applicable amendments for a more complete description of the Plan’s provisions. Copies of these documents are available from the Plan Administrator, Comcast Corporation (“Comcast”, the “Company” or the “Plan Administrator”).

The Plan is a defined contribution plan qualified under Internal Revenue Code (the “Code”) Sections 401(a), 401(k) and 401(m). The original Plan has been amended and restated to reflect mergers of other plans with and into the Plan and to make certain other technical, compliance and design changes. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (“ERISA”).

Employees become eligible to participate in the Plan in the first month after completion of three months of service and shall be automatically enrolled in the Plan at a contribution rate equal to two percent of eligible compensation on a pre-tax basis unless they opt out of participation. Automatically-enrolled participants may thereafter increase or decrease their contribution. The maximum amount of eligible compensation that may be deferred is 50%, subject to certain limits imposed by the Code. The Company matches 100% of the participant’s contribution up to 4.5% of the participant’s eligible compensation for such payroll period. The maximum Company matching contribution for a Plan year is $10,000 for any participant who is a Highly Compensated Employee and whose Annual Rate of Pay (as both terms are defined in the Plan) is more than $200,000. Rollover contributions represent participant assets transferred to the Plan from other qualified retirement plans.

Each participant has at all times a 100% nonforfeitable interest in the participant’s contributions and earnings attributable thereto. Company matching contributions for Plan years beginning after December 31, 2000 are fully and immediately vested. Company matching contributions for Plan years ended on or prior to December 31, 2000 vested according to years of service.

Each participant has the right, in accordance with the provisions of the Plan, to direct the investment by the Trustee of the Plan of all amounts allocated to the separate accounts of the participant under the Plan among any one or more of the investment fund options. The Trustee pays benefits and expenses upon the written direction of the Plan Administrator. The participants in the Plan are assessed a $19 per year administrative fee per account.

Amounts contributed by the Company which are forfeited by participants as a result of the participants’ separation from service prior to becoming 100% vested shall be used to reduce the Company’s required contributions. Pending application of the forfeitures, the Company may direct the Trustee to hold the forfeitures in cash or under investment in a suspense account. If the Plan should terminate with any forfeitures not applied against Company contributions, they will be allocated to then current participants in the proportion that each participant’s eligible compensation for that Plan year bears to the eligible compensation for all such participants for the Plan year. Forfeitures used for the year ended December 31, 2011 amounted to $101,888. Outstanding forfeitures not yet applied against Company contributions at December 31, 2011 and 2010 were $1,417 and $4,671, respectively.

Any participant who has a separation from service for any reason shall be entitled to receive his/her vested account balance. Upon death, disability or attainment of age 65, a participant’s account becomes fully vested in all Company contributions regardless of the participant’s years of service. Generally, distribution will start no later than 60 days after the close of the Plan year in which the participant’s separation from service occurs, subject to certain deferral rights under the Plan. The distribution alternatives permitted are a lump sum payment, annual or quarterly installments, a rollover into another qualified plan, or any combination of the foregoing.

Trustee

Fidelity Management Trust Company is the appointed Trustee of the Plan.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The financial statements of the Plan are presented using the accrual basis of accounting. The Plan’s investments are stated at fair value. Fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company’s Class A and Class A Special common stock are valued at their respective closing price reported on the NASDAQ Global Select Market on the last business day of the Plan year. Money market funds are stated at amortized cost, which approximates fair value. Shares of mutual funds are valued at the net asset value of shares held by the Plan at year-end. The stable value fund is stated at fair value and then adjusted to contract value as described below. Fair value of the stable value fund is the net asset value of its underlying investments and

4

Table of Contents

contract value is principal plus accrued interest. Notes receivable from participants are measured at their unpaid principal balance plus any accrued but unpaid interest.

Investment contracts, such as those included in the Comcast Stable Value Fund, are required to be reported at fair value. However, contract value is the relevant measure of fully benefit-responsive investment contracts since that is the amount participants would receive if they were to initiate permitted transactions under the terms of the Plan. As required by accounting principles generally accepted in the United States (“U.S. GAAP”), the Statements of Net Assets Available for Benefits present investments at fair value as well as an additional line item showing the adjustment of fully benefit-responsive investment contracts from fair value to contract value. The Statement of Changes in Net Assets Available for Benefits is presented on a contract value basis.

Net unrealized appreciation or depreciation in the financial statements reflects changes in fair value of investments held at year end, while net realized gains and losses associated with the disposition of investments are recorded as of the trade date and calculated based on fair value as of such date. Dividends are recorded on the ex-dividend date. Interest income is recorded on the accrual basis. Benefits are recorded when paid.

Investment securities are exposed to various risks, such as interest rate, market and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and such changes could materially affect the amounts reported in the Statement of Net Assets Available for Benefits.

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and changes therein, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates.

In January 2010, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2010-06, Fair Value Measurements and Disclosures , which amends ASC 820, Fair Value Measurements and Disclosures , adding a new disclosure requirement to provide Level 3 activity of purchases, sales, issuances, and settlements on a gross basis. This requirement is effective for fiscal years beginning after December 15, 2010. The adoption in 2011 did not materially affect the Plan’s financial statements.

In May 2011, the FASB issued ASU No. 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs , which amends ASC 820. ASU No. 2011-04 clarifies the FASB’s intent about the application of existing fair value measurement and disclosure requirements under ASC 820. This ASU requires the categorization by level for items that are required to be disclosed, but not measured, at fair value. This ASU also requires additional disclosure of information about transfers between Level 1 and Level 2 of the fair value hierarchy and additional disclosure regarding the sensitivity of Level 3 measurements of fair value to changes in unobservable inputs and any interrelationships between those inputs. In addition, the ASU provides guidance on measuring the fair value of financial instruments managed within a portfolio and the application of premiums and discounts on fair value measurements. The new guidance is effective for reporting periods beginning after December 15, 2011. The adoption will not have a material effect on the Statement of Net Assets Available for Benefits and Statement of Changes in Net Assets Available for Benefits.

During 2011, the Plan’s investments, including investments purchased and sold, as well as held during the year, appreciated (depreciated) in fair value as follows (in thousands):

Common stock — Comcast Class A	$ 17,802
Comcast Class A Special	4,300
Total common stock	22,102
Mutual funds
Domestic stock funds	(28,022	)
International stock funds	(53,661	)
Balanced funds	(7,862	)
Fixed income funds	271
Total mutual funds	(89,274	)
Separate account	3,947
Common collective trusts	(3,507	)
	$ (66,732	)

As described in Note 2, included in the Comcast Stable Value Fund are fully benefit-responsive investment contracts, which are carried at contract value. The rate at which interest is credited to the Plan is that determined under the contract, consistent with reflecting participant balances at contract value as opposed to the market value of the underlying assets. Interest rates are reset quarterly by the issuers of the investment contracts.

The average yield of investment contracts held as of December 31, 2011 and 2010 was 1.99% and 2.30%, respectively. When adjusted to reflect the actual interest credited to the Plan, the average yield of investment contracts held as of December 31, 2011 and 2010 was 2.11% and 2.12%, respectively.

The following table summarizes the adjustments from fair value to contract value related to the fully benefit-responsive investment contracts included in the Comcast Stable Value Fund (in thousands):

State Street Bank and Trust Company Boston	2011 Credit Rating — AA-	2011 — $ (5,167	)	2010 — $ (3,470	)
JP Morgan Chase	A+	(7,008	)	(4,705	)
Natixis	A+	(5,166	)	(3,470	)
AIG Financial Products Corp	A-	(3,324	)	(2,235	)
		$ (20,665	)	$ (13,880	)

There are certain events, such as the Plan’s failure to qualify under Section 401(a) or 401(k) of the Code, which can limit the fund’s ability to transact at contract value. At this time, the occurrence of any such limiting event is not probable.

A contract issuer may terminate a contract at any time. Settlement upon termination will be at contract value unless the terms of the contract were not met or the Trustee’s authority over the Plan is limited or terminated.

1. FAIR VALUE MEASUREMENTS

ASC 820 establishes a hierarchy that prioritizes fair value measurements based on the types of inputs used for the various valuation techniques. The levels of the hierarchy are described below:

Level 1	Consists of financial instruments whose values are based on quoted market prices for identical financial instruments in an active market.
Level 2	Consists of financial instruments that are valued using models or other valuation methodologies. These models

Table of Contents

use inputs that are observable either directly or indirectly and include:

• Quoted prices for similar assets or liabilities in active markets;

• Quoted prices for identical or similar assets or liabilities in markets that are not active;

• Pricing models whose inputs are observable for substantially the full term of the financial instrument;

• Pricing models whose inputs are derived principally from or corroborated by observable market data through correlation or other means for substantially the full term of the financial instrument.

Level 3 Consists of financial instruments whose values are determined using pricing models that use significant inputs that are primarily unobservable, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant judgment or estimation.

The asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

The valuation methodologies used for assets measured at fair value are as follows:

Mutual funds, separate account and common collective trusts: Valued at the net asset value of shares held by the Plan at year end.

Common stocks: Valued at the closing price reported on the active market on which the individual securities are traded.

Guaranteed investment contracts: Valued at fair value by discounting the related cash flows based on current yields of similar instruments with comparable durations considering the credit-worthiness of the issuer.

The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Plan believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

The table below sets forth by level, within the fair value hierarchy, the Plan’s assets at fair value as of December 31, 2011 and 2010 (in thousands).

| Assets at Fair Value as of
December 31, 2011 | Level 1 | Level 2 | Level 3 | Total |

1. PARTICIPANT LOANS AND HARDSHIP WITHDRAWALS

A participant may borrow from his/her Plan account subject to the approval of the Plan Administrator in accordance with applicable regulations issued by the Internal Revenue Service (“IRS”) and the Department of Labor. In general, a participant may borrow a minimum of $500 up to a maximum of the lesser of $50,000 or 50% of the participant’s nonforfeitable accrued benefit on the valuation date (as defined by the Plan) last preceding the date on which the loan request is processed by the Plan Administrator. The maximum term of a loan made pursuant to the Plan is five years (loans with terms of greater than five years exist under the Plan as a result of rollovers from merged plans). Interest accrues at the rate of prime plus 1% as of the month the loan application is approved. Principal and interest are paid through payroll deductions or participant initiated payments. Interest rates ranged from 4.25% to 9.50% for the year ended December 31, 2011. Maturities on active outstanding loans ranged from 2012 to 2038 for the year ended December 31, 2011. Loan transactions are treated as a transfer between the investment fund and notes receivable from participants.

Effective after a calendar quarter of non-repayment, a loan is considered to be in default. Defaulted loans are treated as distributions for tax purposes and become taxable income to the participant in the year in which the default occurs.

A participant may withdraw all or a portion of his/her benefits derived from salary reduction, rollovers or the vested portion of employer contributions, and earnings thereon, on account of hardship, as defined by the Plan and applicable IRS regulations. Under these rules, the participant must exhaust the possibilities of all other distributions, loans, etc. available under the Plan and meet certain other requirements. Upon receiving a hardship withdrawal, the participant’s elective contributions are suspended for six calendar months.

1. ADMINISTRATION OF THE PLAN

The Company, as Plan Administrator, has the authority to control and manage the operation and administration of the Plan and may delegate all or a portion of the responsibilities of controlling and managing the operation and administration of the Plan to one or more persons.

1. PLAN TERMINATION

Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, each affected participant’s account balance will become fully vested.

1. FEDERAL TAX CONSIDERATIONS

a. Income Tax Status of the Plan —On May 8, 2009, the Plan received an updated determination letter from the IRS stating that the Plan, as amended and restated December 12, 2007, is qualified and that the trust established under the Plan is tax-exempt. Therefore, no provision for income taxes has been included in the Plan’s financial statements.

b. Impact on Plan Participants —Matching contributions and salary reduction contributions, as well as earnings on Plan assets, are generally not subject to federal income tax until distributed from a qualified plan that meets the requirements of Sections 401(a), 401(k) and 401(m) of the Code.

c. Evaluation of Tax Position —In accordance with Accounting Standards Codification (ASC) 740-10-50-15 c – e, the Plan Administrator has analyzed the tax positions taken by the Plan and has concluded that as of December 31, 2011, there are no uncertain positions taken or expected to be taken that would require recognition of a liability (or asset) or disclosure in the financial statements. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress. The Plan Administrator believes the Plan is no longer subject to income tax examinations for years prior to 2008.
