Consolidated Financial Results

Revenue increased 51.1% in the third quarter of 2011 to $14.3 billion, while Operating Cash Flow increased 27.8% to $4.6 billion and Operating Income increased 35.1% to $2.6 billion, primarily reflecting strong Cable Communications results, the acquisition of NBCUniversal in January and the consolidation of the Universal Orlando theme parks.

For the nine months ended September 30, 2011, revenue increased 44.6% to $40.8 billion, while operating cash flow increased 23.5% to $13.4 billion and operating income increased 30.8% to $7.8 billion.

Earnings per Share¹ (EPS) for the third quarter of 2011 was $0.33, a 6.5% increase from the $0.31 reported in the third quarter of 2010. Excluding NBCUniversal transaction and related costs, EPS increased 3.1% (see Table 4). Third quarter EPS was negatively impacted by higher interest expense and taxes, as well as a $256 million year-over-year decline in investment income. This decline reflects a $147 million ($0.03 per share after tax) investment loss in third quarter 2011, compared to a $109 million ($0.02 per share after tax) investment gain in third quarter 2010, driven primarily by noncash mark-to-market adjustments on our investment portfolio.

EPS for the nine months ended September 30, 2011 was $1.03, a 10.8% increase from the $0.93 reported in the prior year. Excluding NBCUniversal transaction and related costs and a $137 million noncash, non-recurring income tax charge resulting from a state tax law change during the second quarter of 2011, EPS for the nine months ended September 30, 2011 increased 14.6% to $1.10 compared to $0.96 in 2010 (see Table 4).

Free Cash Flow (excluding any impact from the Economic Stimulus packages) increased 35.8% to $1.4 billion in the third quarter of 2011 compared to $1.0 billion in last year’s third quarter. The increase in free cash flow primarily reflects growth in consolidated operating cash flow, partially offset by an increase in working capital. Free cash flow for the nine months ended September 30, 2011 increased 20.3% to $5.1 billion compared to $4.3 billion in 2010.

Note: The definition of Free Cash Flow excludes any impact from the 2008-2011 Economic Stimulus packages. These amounts have been excluded from Free Cash Flow to provide an appropriate comparison. NM=comparison not meaningful.

Share Repurchases and Dividends. During the third quarter of 2011, Comcast repurchased 27.5 million of its common shares for $600 million. Year to date, Comcast has repurchased 73.4 million of its common shares for $1.65 billion. As of September 30, 2011, Comcast had approximately $491 million of availability remaining under its share repurchase authorization. In addition, during the third quarter of 2011, Comcast paid dividends totaling $309 million.

Cable Networks

For the third quarter of 2011, revenue from the Cable Networks segment increased 12.0% to $2.1 billion compared to $1.9 billion in the third quarter of 2010, driven by a 10.2% increase in distribution revenue, a 9.5% increase in advertising revenue and a 37.2% increase in other revenue primarily due to increases in the licensing of owned content from the cable production studio.

Broadcast Television

For the third quarter of 2011, revenue from the Broadcast Television segment increased 2.9% to $1.5 billion, reflecting higher content licensing revenue, partially offset by ratings pressure at the NBC broadcast network and lower political advertising at NBC owned local stations. In the third quarter, the Broadcast Television segment generated an operating cash flow loss of $7 million compared to operating cash flow of $70 million in the third quarter of 2010, reflecting increased investment in primetime, news programming, and local stations, as well as acquisition-related accounting revisions totaling $24 million.

5

Filmed Entertainment

For the third quarter of 2011, revenue from the Filmed Entertainment segment decreased 7.8% to $1.1 billion compared to $1.2 billion in the third quarter of 2010, driven by lower theatrical revenue compared to the prior year, partially offset by higher home entertainment revenue from Bridesmaids and the international release of Fast Five. Third quarter operating cash flow decreased 16.9% to $54 million compared to $66 million in the third quarter of 2010, reflecting lower revenue partially offset by favorable acquisition-related accounting adjustments totaling $36 million. Excluding these accounting revisions, third quarter 2011 operating cash flow was $18 million compared to $66 million in last year’s third quarter (see Table 6).

For the nine months ended September 30, 2011, revenue from the Filmed Entertainment segment increased 1.2% to $3.3 billion and generated an operating cash flow loss of $65 million compared to operating cash flow of $58 million in the first nine months of 2010.

Theme Parks

On July 1, 2011, NBCUniversal completed the acquisition of the 50% interest in Universal Orlando that it did not previously own. As a result, Theme Parks segment revenue includes the results of Universal Hollywood, Universal Orlando and international licensing fees. Operating cash flow includes the results of Universal Hollywood and Universal Orlando.

For the third quarter of 2011, revenue from the Theme Parks segment increased 9.1% to $580 million compared to $531 million in the third quarter of 2010, reflecting strong performances at the Hollywood and Orlando parks. Third quarter operating cash flow increased 12.6% to $285 million compared to $252 million in the same period last year, driven by the strength of The Wizarding World of Harry Potter^TM attraction in Orlando and the King Kong^TM attraction in Hollywood.

For the nine months ended September 30, 2011, revenue from the Theme Parks segment increased 32.9% to $1.5 billion compared to $1.1 billion in 2010. Operating cash flow increased 61.2% to $644 million compared to $399 million in the first nine months of 2010.
