    PHILADELPHIA, August 2, 2005 -- Comcast Corporation (Nasdaq: CMCSA, CMCSK)
today reported results for the quarter ended June 30, 2005. Comcast will discuss
second quarter results on a conference call and webcast today at 8:30 AM Eastern
Time. A live broadcast of the conference call will be available on the investor
relations website at www.cmcsa.com and www.cmcsk.com.

    Brian L. Roberts, Chairman and CEO of Comcast Corporation said, "This is our
20th consecutive quarter reporting double-digit operating cash flow growth and,
at 40.8%, cable's Operating Cash Flow margins are the highest in 2 1/2 years. We
are posting solid results in the second quarter with revenue growth of 10.5% and
Operating Cash Flow growth of 13.2%. Operating income increased 23.2% to $1.0
billion.

    "Our consistently strong performance - double-digit revenue and cash flow
growth and free cash flow growth above 20% - demonstrates the inherent strength
of our business and reinforces our confidence in the future.

    "We are extending our competitive advantage with industry-leading products.
In video, we are continuing to expand our ON DEMAND, HDTV and DVR offerings and
are beginning to rollout our enhanced basic - 100% digital service. We recently
announced an important new agreement with Starz Encore that significantly
enhances our ON DEMAND service, adding more than 325 top movies a month to the
3,500 program choices our customers enjoy today. In June, our customers viewed
over 112 million ON DEMAND programs, a 10 million increase in 3 months, as we
continue to provide an unmatched product with more choice and customer value.

    "We also recently announced a 50% increase in the speed of our high-speed
Internet service - now 6 megabits per second - and continue to deliver a growing
array of valuable enhancements and features like security and online gaming. Our
strategy of product innovation and differentiation is working - we added 1.1
million revenue generating units during the first six months of this year - more
than we did in the first half of last year.

    "We believe Comcast Digital Voice will be the next engine for growth and are
ramping up the rollout of this service in markets like Philadelphia,
Indianapolis, Boston, Hartford, Chicago and Portland. We are on track to extend
our offering to 15 million homes in 20 markets by year end and expect to offer
our fully-featured digital voice service across our 41 million homes by the end
of 2006.



    "We are excited about the future of our business and are positioning Comcast
to continue to deliver the best entertainment and communications services to our
customers and to build value for our shareholders."

    Comcast Cable Results
    Cable results for the quarter and the six months ended June 30, 2005 are
presented on a pro forma basis. Pro forma cable results adjust only for certain
acquisitions and dispositions and are presented as if the acquisitions and
dispositions were effective on January 1, 2004. Please refer to Table 7-A for a
reconciliation of pro forma data.

    Second Quarter 2005
    Comcast Cable reported revenue of $5.3 billion for the quarter ended June
30, 2005, representing a 10.1% increase from the second quarter of 2004. Comcast
Cable added 507,000 revenue generating units in the second quarter of 2005, an
increase of 22.1% from the 415,000 added in the same quarter last year.

    Video revenue increased $192 million or 5.9% to $3.4 billion in the second
quarter of 2005, driven by higher monthly revenue per basic subscriber and a
13.3% increase in the number of digital customers. Comcast Cable added 284,000
new digital customers in the second quarter of 2005 and with more than 9.1
million subscribers, digital cable penetration reached 42.6% of basic
subscribers. As expected, basic subscribers are essentially unchanged from a
year ago at 21.4 million, and declined seasonally by 77,000 or 0.2% from the
first quarter of 2005.

    Digital cable subscriber and video revenue growth reflects strong consumer
demand for new digital features and services including Comcast ON DEMAND,
high-definition television (HDTV) programming and digital video recorders
(DVRs), as well as the initial rollout of an enhanced basic - 100% digital
service in a number of markets. During the second quarter, pay-per-view revenues
increased 24.0% - the seventh consecutive quarter of pay-per-view revenue
growth, driven by more movie and event purchases through the Comcast ON DEMAND
service. During the second quarter, Comcast Cable deployed nearly 300,000
advanced set-top boxes with DVR and/or HDTV programming capability, generating
an incremental $5 to $10 of monthly revenue per box.

    Comcast High-speed Internet service revenues increased 28.8% to $982 million
in the second quarter of 2005, reflecting a 28.3% increase in subscribers and
strong average revenue per subscriber. Comcast Cable ended the second quarter of
2005 with more than 7.7 million high-speed Internet subscribers, adding 297,000
subscribers during the second quarter of 2005 for a penetration rate of 18.9% of
available homes. Average monthly revenue per high-speed Internet subscriber of
$43.34 in the second quarter of 2005, was in line with the second quarter of
2004 and increased $0.53 from the $42.81 reported in the first quarter of 2005.



    Advertising revenue for the second quarter of 2005 increased 9.9% to $362
million, reflecting growth of 6.5% in local advertising and growth of 16.7% in
regional/national advertising as a result of the continuing success of our
regional interconnect strategy. The growth in advertising revenue during the
quarter was slightly offset by a decline in political advertising when compared
to the prior year. Advertising revenue growth in the second half of 2005 will
reflect a significant decline in political advertising when compared to the 2004
election year.

    Comcast Cable added 15,000 Comcast Digital Voice customers (CDV - Comcast's
phone service using IP technology), reflecting the rollout of CDV in new markets
late in the second quarter. As expected, CDV customer additions were offset by a
decline in the number of Comcast's circuit-switched telephone customers as
Comcast transitions to marketing Comcast Digital Voice. Comcast Cable reported
2,000 net new phone customers in the second quarter of 2005. Cable phone revenue
declined 4.0% from the second quarter of 2004 to $170 million in the second
quarter of 2005, due primarily to a decline in access revenue per customer.

    Cable operating income before depreciation and amortization (Operating Cash
Flow) grew 13.2% to $2.2 billion in the second quarter, an increase from the
$1.9 billion reported for the second quarter of 2004. Second quarter 2005
Operating Cash Flow margin increased to 40.8% from 39.7% in the second quarter
of 2004.

    Cable capital expenditures increased 4.8% to $936 million compared to the
$893 million in the second quarter of the prior year. The increase in capital
expenditures reflects the purchase of digital set-top boxes to meet expected
demand, as well as certain capital investments, including equipment for digital
simulcasting and our integrated service platform, which are expected to decline
in the second half of 2005.

    Year-to-date June 2005
    For the six months ended June 30, 2005, Comcast Cable reported revenue of
$10.4 billion, representing a 9.9% increase from the prior year. Comcast Cable
added a total of 1.1 million new revenue generating units during the first half
of 2005, a 7.9% increase from the first half of last year.

    Video revenue increased 5.8% during the period, driven by higher monthly
revenue per basic subscriber and a 13.3% increase in the number of digital
customers. Comcast Cable added nearly 484,000 digital cable subscribers during
the first six months of 2005 to end the period with more than 9.1 million
digital subscribers. Comcast Cable basic subscribers declined 106,000 during the
first six months of 2005, ending the period at 21.4 million subscribers.

    Comcast Cable added nearly 712,000 high-speed Internet subscribers during
the first half of 2005 to end the period with more than 7.7 million subscribers.
Revenues for this service increased 30.6% from the prior year to $1.9 billion,
reflecting strong year over year subscriber growth. Advertising revenue
increased 9.8% from the same period of 2004 to $658 million, including the
decline in political advertising from the 2004 election year. Cable phone
revenue declined 3.5% from the same period one year ago to $343 million,
primarily due to lower revenue per customer. Comcast Cable added 7,000 phone
subscribers in the first six months of 2005 compared to a loss of 42,000
subscribers in the first half of 2004.



    Operating Cash Flow grew 14.5% from the same period one year ago to $4.2
billion, reflecting strong revenue growth and the Company's success in
controlling the growth of operating costs. Operating Cash Flow margin for the
first six months of 2005 increased to 40.0% from 38.4% during the first six
months of the prior year. Comcast Cable capital expenditures were $1.8 billion
for the first six months of 2005 compared to $1.7 billion last year. As
previously described, the level of capital expenditures is expected to decline
in the second half of 2005.

    Content
    Comcast's content segment consists of our national networks E! Entertainment
Television and Style Network (E! Networks), The Golf Channel, Outdoor Life
Network, G4 and AZN Television (formerly International Channel Networks).

    Comcast's content segment reported second quarter 2005 revenue of $234
million, a 17.7% increase from the second quarter of 2004 reflecting increases
in distribution and advertising revenue for all the networks. The content
segment reported Operating Cash Flow of $97 million in the second quarter of
2005, a 25.4% increase above the second quarter of 2004.

    For the six months ended June 30, 2005, Comcast's content segment reported
revenue of $447 million, a 19.2% increase compared to the prior year period, and
Operating Cash Flow of $174 million, an increase of 19.1% from the same time
last year.

    Corporate and Other
    Corporate and Other includes Comcast-Spectacor, corporate overhead and other
operations and eliminations between Comcast's businesses. In the second quarter
of 2005, we reported Corporate and Other revenue of $36 million and an Operating
Cash Flow loss of $63 million as compared to revenue of $28 million and an
Operating Cash Flow loss of $45 million in the second quarter of 2004.

    For the six months ended June 30, 2005, Corporate and Other revenue declined
to $83 million from the $114 million reported in the same period of 2004. The
Operating Cash Flow loss for the year-to-date period ended June 30, 2005, was
$105 million compared to $100 million in 2004. Results for the six month period
and the quarter ended June 30, 2005, were impacted by the absence of National
Hockey League games.

    Consolidated Results
    For the three months ended June 30, 2005, the Company reported consolidated
revenues of $5.6 billion, a 10.5% increase from the $5.1 billion reported in the
same period of 2004. Consolidated Operating Cash Flow increased to $2.2 billion
or 13.2%, in the second quarter of 2005, from the $2.0 billion reported in the
same prior year period. Operating income increased to $1.0 billion in the second
quarter of 2005 compared to operating income of $852 million in the second
quarter of 2004.

    Free Cash Flow (described further on Table 4) was $422 million in the second
quarter of 2005 compared to $500 million reported in the second quarter of 2004,
reflecting increases in Operating Cash Flow and capital expenditures and the
timing of income tax payments in the second quarter of 2005. For the three
months ended June 30, 2005, the Company reported consolidated net income of $430
million or $0.19 per share compared to consolidated net income of $262 million
or $0.12 per share in the second quarter of 2004. The increase in net income is
primarily due to the growth in Operating Cash Flow.



    For the six months ended June 30, 2005, consolidated revenue increased 9.9%
to $11.0 billion from the $10.0 billion reported in the same period of 2004. The
Operating Cash Flow for the period ended June 30, 2005 was $4.2 billion, an
increase of 15.0% when compared to $3.7 billion in 2004. Operating income
increased to $1.9 billion in the first half of 2005 compared to operating income
of $1.5 billion during the first half of 2004.

    Free Cash Flow was $1.1 billion during the year-to-date period, an increase
of 27.5% from the $897 million reported during the same period of last year. For
the six months ended June 30, 2005, the Company reported consolidated net income
of $573 million or $0.26 per share compared to consolidated net income of $327
million or $0.14 per share in the six months ended June 30, 2004. The increase
in year-to-date net income is due primarily to the growth in Operating Cash
Flow.

(1)  Free Cash Flow is defined as Operating Cash Flow less net interest, cash
     paid for taxes, and capital expenditures. It is unaffected by fluctuations
     in working capital levels from period to period and cash payments
     associated with intangible and other noncurrent assets. Cash payments for
     intangible and other noncurrent assets include long-term technology license
     agreements including computer software, long term rights to service
     multi-dwelling properties and programming content for our cable networks.
     In 2005, cash payments for intangibles and other noncurrent assets of $305
     million included licenses and software intangibles of approximately $105
     million, multiple dwelling unit contracts of approximately $67 million and
     acquisitions of additional ownership interests in certain of our majority
     owned subsidiaries. In 2004, cash payments for intangible assets of $453
     million included a long-term strategic license agreement with Gemstar of
     approximately $250 million, other licenses and software intangibles of $104
     million and multiple dwelling unit contracts of $69 million. In 2005, cash
     payments for acquisitions and investments totaling $439 million included
     MGM Inc., Liberate Technologies, and MetaTV. In 2004, cash payments for
     acquisitions primarily related to the acquisition of TechTV.

(2)  Includes interest expense net of interest income and excludes non-cash
     interest and subsidiary preferred dividends.

(3)  Free Cash Flow excludes amounts necessary to reconcile Free Cash Flow to
     "Net Cash Provided by Operating Activities Less Capital Expenditures." In
     2005, this amount includes $383 million in cash payments for liabilities
     incurred as part of the acquisition of AT&T Broadband, including $220
     million in payments representing our share of the settlement payments
     related to certain AT&T litigation. In 2004, this amount includes income
     tax refunds of $536 million offset by $199 million in cash payments for
     liabilities recorded as part of the acquisition of AT&T Broadband.

    Non-GAAP and Other Financial Measures

    Operating Cash Flow is the primary basis used to measure the operational
strength and performance of our businesses. Free Cash Flow is an additional
performance measure used as an indicator of our ability to repay debt, make
investments and return capital to investors, principally through stock
repurchases. We use Debt Excluding Exchangeables as a measure of debt that will
require cash from future operations or financings. We also adjust certain
historical data on a pro forma basis following significant acquisitions or
dispositions to enhance comparability.

    Operating Cash Flow is defined as operating income before depreciation and
amortization and impairment charges, if any, related to fixed and intangible
assets and gains or losses from the sale of assets, if any. As such, it
eliminates the significant level of non-cash depreciation and amortization
expense that results from the capital intensive nature of our businesses and
intangible assets recognized in business combinations, and is unaffected by our
capital structure or investment activities. Our management and Board of
Directors use this measure in evaluating our consolidated operating performance
and the operating performance of all of our operating segments. This metric is
used to allocate resources and capital to our operating segments and is a
significant component of our annual incentive compensation programs. We believe
that Operating Cash Flow is also useful to investors as it is one of the bases
for comparing our operating performance with other companies in our industries,
although our measure of Operating Cash Flow may not be directly comparable to
similar measures used by other companies.

    As Operating Cash Flow is the measure of our segment profit or loss, we
reconcile it to operating income, the most directly comparable financial measure
calculated and presented in accordance with Generally Accepted Accounting
Principles (GAAP), in the business segment footnote of our quarterly and annual
financial statements. Therefore, we believe our measure of Operating Cash Flow
for our business segments is not a "non-GAAP financial measure" as contemplated
by Regulation G adopted by the Securities and Exchange Commission. Consolidated
Operating Cash Flow is a non-GAAP financial measure.

    Free Cash Flow, which is a non-GAAP financial measure, is defined as
Operating Cash Flow less net interest, cash paid for taxes, and capital
expenditures. As such, it is unaffected by fluctuations in working capital
levels from period to period and cash payments associated with intangible and
other non-current assets which are detailed in our quarterly and annual reports
on Forms 10Q/K. We believe that Free Cash Flow is also useful to investors as it
is one of the bases for comparing our operating performance with other companies
in our industries, although our measure of Free Cash Flow is accrual-based and
may not be comparable to similar measures used by other companies.

    Debt Excluding Exchangeables, which is a non-GAAP financial measure, refers
to the aggregate amount of our consolidated debt and capital lease obligations
less the amount of notes that are collateralized by securities that we own.



    Pro forma data is used by management to evaluate performance when
significant acquisitions or dispositions occur. Historical data reflects results
of acquired businesses only after the acquisition dates while pro forma data
enhances comparability of financial information between periods by adjusting the
data as if the acquisitions (or dispositions) occurred at the beginning of the
prior year. Our pro forma data is only adjusted for the timing of acquisitions
and does not include adjustments for costs related to integration activities,
cost savings or synergies that have been or may be achieved by the combined
businesses. We believe our pro forma data is not a non-GAAP financial measure as
contemplated by Regulation G.

    Operating Cash Flow and Free Cash Flow should not be considered as
substitutes for operating income (loss), net income (loss), net cash provided by
operating activities or other measures of performance or liquidity reported in
accordance with GAAP. Debt Excluding Exchangeables should not be considered as a
substitute for Total Debt. Additionally, in the opinion of management, our pro
forma data is not necessarily indicative of future results or what results would
have been had the acquired businesses been operated by us after the assumed
earlier date.

    Following are quantitative reconciliations of Free Cash Flow, Debt Excluding
Exchangeables, Consolidated Operating Cash Flow, and, although not required by
Regulation G, reconciliations of business segment Operating Cash Flow and pro
forma data.
