Philadelphia, PA – May 3, 2011 …Comcast Corporation (NASDAQ: CMCSA, CMCSK) today reported results for the quarter ended March 31, 2011, including the results of NBCUniversal after January 28, 2011.

Brian L. Roberts, Chairman and Chief Executive Officer of Comcast Corporation, said, “We are off to a terrific start in 2011. Cable had an outstanding quarter with continuing momentum in both our residential and Business Services operations. We had particularly strong growth in high-speed Internet, consistent growth in voice services, and improving video customer results. In addition, our customer retention and service metrics have never been better, and we are leading the industry in delivering new products and innovations to our customers.

The performance of NBCUniversal was led by our cable networks, which posted strong growth across the board. While we’ve only been operating the NBCUniversal businesses for three months, we’re encouraged by a seamless integration, and we are working diligently to invest and build value for our shareholders.

As we begin 2011, we remain focused on execution, which includes driving product leadership and innovation, enhancing our customers’ experience, expanding the entertainment choices we offer consumers and realizing the opportunities of our wonderful company.”

Consolidated Financial Results

Revenue increased 31.8% in the first quarter of 2011 to $12.1 billion, while Operating Cash Flow increased 14.1% to $4.1 billion and Operating Income increased 14.9% to $2.2 billion, primarily reflecting strong Cable Communications and Cable Networks results and the consolidation of NBCUniversal as of January 28, 2011. Excluding NBCUniversal transaction and related costs in the first quarter of 2011 and $14 million in the first quarter of 2010, Operating Cash Flow grew 16.6% (see Table 4).

Earnings per Share¹ (EPS) for the first quarter of 2011 was $0.34, a 9.7% increase from the $0.31 reported in the first quarter of 2010. Excluding NBCUniversal transaction and related costs, first quarter 2011 EPS increased 16.1% to $0.36 compared to $0.31 in the first quarter of 2010 (see Table 4).

Free Cash Flow increased 17.7% to $2.2 billion in the first quarter of 2011 from $1.9 billion in the first quarter of 2010. The increase in Free Cash Flow primarily reflects growth in consolidated operating cash flow, partially offset by higher capital expenditures.

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 first quarter of 2011, Comcast repurchased 23.3 million of its common shares for $525 million. As of March 31, 2011, Comcast had approximately $1.6 billion of availability remaining under its share repurchase authorization. In addition, during the first quarter of 2011, Comcast paid dividends totaling $262 million. Our dividend payment on April 27, 2011, reflected our previously announced 19% increase to $0.1125 per share compared to $0.0945 per share paid in the first quarter.

Pro Forma Financial Results

Pro forma results are presented as if the NBCUniversal transaction, which closed on January 28, 2011, was effective on January 1, 2010. These results are based on historical results of operations, adjusted for the effects of acquisition accounting and eliminating the costs and expenses directly related to the transaction, and are not necessarily indicative of what the results would have been had we operated NBCUniversal since January 1, 2010. These adjustments are subject to change as our acquisition accounting is finalized. (See Table 5 for reconciliations of pro forma financial data).

Consolidated Pro forma Revenue of $13.3 billion was flat compared to last year’s results, which includes revenue generated by the 2010 Vancouver Olympics. Excluding the impact of the Olympics, pro forma revenue increased 6.1%. Consolidated Pro forma Operating Cash Flow increased 7.8% to $4.2 billion compared to the first quarter of 2010. Excluding the Olympics and NBCUniversal non-recurring transaction-related costs that are included in our pro forma results, Operating Cash Flow increased 4.2% (see Table 6).

Cable Communications

Pro forma Cable Communications (“Cable”) results include our Video, High-Speed Internet, Voice, Advertising and Business Services operations and the businesses of Comcast Interactive Media that were not contributed to NBCUniversal. Pro forma Cable results exclude our Regional Sports Networks, which were contributed to NBCUniversal.

Revenue. For the first quarter of 2011, Cable revenue increased 5.8% to $9.1 billion compared to $8.6 billion in the first quarter of 2010. This increase reflects growth across our residential Video, High-Speed Internet and Voice services, a 49.9% increase in Business Services and a 10.4% increase in advertising revenue. Reflecting a growing number of residential customers taking multiple products, rate adjustments, and a higher contribution from Business Services, monthly average total revenue per video customer increased 9.3% to $132.91.

Operating Cash Flow. For the first quarter of 2011, Cable Operating Cash Flow increased 7.7% to $3.7 billion compared to $3.5 billion in last year’s first quarter. This quarter’s Operating Cash Flow margin was 41.3% compared to 40.5% in the first quarter of 2010. These results primarily reflect continued benefits from operational efficiencies, partially offset by increases in video programming and marketing expenses, as well as continued investment to expand our capabilities in Business Services.

Capital Expenditures. For the first quarter of 2011, Cable capital expenditures increased 15.4% to $1.1 billion, reflecting increases in customer premise equipment (CPE) as we complete our All-Digital initiative, increased investment in network infrastructure to enable faster speeds in our High-Speed Internet business, and increased investment to support growth in Business Services.

Customers. As of March 31, 2011, Cable Video, High-Speed Internet and Voice customers totaled 49.0 million, an increase of 1.3 million or 2.8% over the prior year. In the first quarter, combined Video, High-Speed Internet and Voice customers increased by 639,000 or 8.3% over the prior year, and also reflected a sequential improvement from the fourth quarter of 2010 in net additions for all three products.

Comcast’s national cable programming networks, Regional Sports Networks (RSNs), Daily Candy and Fandango, which were contributed to NBCUniversal, are also included in these results.

NBCUniversal Pro forma Revenue of $4.3 billion decreased 11.5% compared to $4.9 billion in the first quarter of 2010 due to $782 million of revenue generated by the 2010 Vancouver Olympics. Excluding the impact of the Olympics, pro forma revenue increased 5.2%. NBCUniversal Pro forma Operating Cash Flow increased 4.9% to $496 million compared to $473 million in the first quarter of 2010.

Cable Networks

First quarter Operating Cash Flow increased 7.2% to $817 million compared to $762 million in the same period last year. These results reflect strong performance across our networks led by our RSNs, Bravo, USA and E!, partially offset by new investments in programming, advertising and promotion.

Broadcast Television

For the first quarter of 2011, revenue from the Broadcast Television segment decreased 34.9% to $1.4 billion compared to $2.1 billion in the first quarter of 2010 due to $782 million of revenue generated by the 2010 Vancouver Olympics. Excluding the impact of the Olympics, revenue increased 4.3% reflecting higher advertising revenue. First quarter Operating Cash Flow was $20 million compared to a loss of $182 million in the same period last year. Excluding the $223 million loss from the Olympics, Operating Cash Flow declined from $41 million to $20 million, primarily reflecting increased programming investment (see Table 6).

Filmed Entertainment

For the first quarter of 2011, revenue from the Filmed Entertainment segment decreased 8.2% to $975 million compared to $1,061 million in the first quarter of 2010, reflecting an increase in content licensing revenue, offset by lower theatrical and home entertainment revenue. First quarter Operating Cash Flow was a loss of $146 million compared to a loss of $12 million in the same period last year reflecting the decline in revenue and higher marketing costs in advance of April 2011 theatrical releases.

Theme Parks

Theme Parks segment revenue includes the results of Universal Hollywood, management fees from Universal Orlando and international licensing fees. Operating Cash Flow includes the results of Universal Hollywood and the equity income (loss) from Universal Orlando, which we eliminate through NBCUniversal Headquarters, Other and Eliminations.

For the first quarter of 2011, revenue for the Theme Parks increased 16.1% to $95 million compared to $82 million in the first quarter of 2010, reflecting the strong performance at the Hollywood park and higher fees from the Orlando parks. First quarter Operating Cash Flow was $41 million compared to a loss of $5 million in the same period last year. These results reflect increased equity income from Universal Orlando driven by the strength of The Wizarding World of Harry Potter attraction.
