Comcast Corporation to Conduct One-Time Stock Option Liquidity Program for Non-Employee Holders of Comcast Stock Options

Philadelphia, PA.

Company to Reduce Ongoing Option Administrative Expenses No Economic Dilution to Result

Comcast Corporation (Nasdaq: CMCSA, CMCSK) announced today that it plans to offer certain non- employee holders of Comcast employee stock options an opportunity to receive value for their options through a targeted stock option liquidity program. The eligible non-employee universe consists of approximately 63,000 holders of roughly 41.8 million options in the aggregate with a current value, based in part by reference to Black-Scholes and other option pricing models, of approximately $125 million. As background, when Comcast acquired AT&T Broadband Corp. in November 2002, former holders of AT&T Corp. employee stock options had their options converted in whole or in part into options on Comcast Class A Common Stock.

Many of these option holders, together with a small number of holders of options on Comcast Class A Special Common Stock, have no ongoing employee affiliation with Comcast. Thus, the traditional purpose of employee stock options, to align the interests of the employer with the employee, no longer applies to the options held by these individuals.

While eligible option holders will be able to receive cash for their options under the program, Comcast will incur no economic dilution from this offering. JPMorgan Chase Bank, Comcast's financial counter party in connection with the stock option liquidity program, will ultimately be funding the cost of providing the program. This will occur through the simultaneous purchase by JPMorgan of new stock options from Comcast having similar economic terms as the options being purchased by Comcast from option holders. As a result, the same number of shares underlying options will remain outstanding upon completion of this one-time offer to non-employee option holders.

The Company will benefit from elimination of ongoing administrative expenses including the indirect employee time associated with servicing this option holder group.

Eligible option holders will receive a mailing with details of the voluntary offer, including when and how they can participate, upon the official launch of the program which is expected in the fourth quarter of 2004. Eligible option holders will have access to program information via the forthcoming mailing, through a dedicated website and through a telephone call center to be provided by Comcast's solicitation agent, Mellon Investor Services.

Comcast today filed a Form S-3 registration statement with the Securities and Exchange Commission relating to certain aspects of the stock option liquidity program, covering the number of shares of Comcast common stock underlying the options that may be sold by Comcast to JPMorgan in connection with the program. J.P. Morgan Securities Inc. is acting as Comcast's financial advisor and as bookrunner and structuring agent in connection with the stock option liquidity program.
