Comcast Corporation to Participate in Credit Suisse First Boston Media Week Conference.

Comcast Corporation today will participate in the Credit Suisse First Boston Media Week Conference in New York City. During the conference, John R. Alchin, Executive Vice President and Treasurer of Comcast Corporation, and David N. Watson, Executive Vice President of Sales, Marketing and Customer Service of Comcast Cable Communications, will highlight the company's strong balance sheet and free cash flow generation capability and detail Comcast's integration plans for the newly acquired AT&T Broadband cable systems.

An important aspect of Comcast's integration plan is the rapid upgrade of the AT&T Broadband cable systems. Comcast plans to invest $2.0 to $2.5 billion over the next two years to complete the upgrade of AT&T Broadband cable systems, which will drive the availability of advanced services like Comcast Digital Cable and High-Speed Internet services in those markets. Comcast estimates total cable capital expenditures for the combined Comcast and AT&T Broadband cable systems will be $4.2 to $4.5 billion in 2003.

A live webcast of the presentation will be available on the Company's Investor Relations website at http://www.cmcsk.com/ at 12 p.m. (EST). An on-demand replay of the presentation will be available via the Internet within 24 hours on the Company's Investor Relations website.
