Kansas City, Missouri (December 23, 2004)—AMC Entertainment Inc. (AMEX: AEN), one of the world's leading theatrical exhibition companies, announced today that the acquisition of AMC by Marquee Holdings Inc. has been completed. Marquee Holdings Inc. is an investment vehicle controlled by affiliates of J.P. Morgan Partners, LLC, the private equity arm of JPMorgan Chase & Co. (NYSE: JPM), and Apollo Management, L.P., a private investment firm. AMC stockholders approved the merger agreement governing the transaction at a special stockholders meeting held on December 23, 2004 in Leawood, Kansas.

        In accordance with the terms of the merger agreement, each outstanding share of AMC common stock and Class B stock has been converted into the right to receive $19.50 per share in cash, and each outstanding share of AMC series A convertible preferred stock has been converted into the right to receive $2,727.27 in cash. Shares of AMC common stock will continue to trade on the American Stock Exchange until the market closes on December 23, 2004 at 4:00 pm (EST) in accordance with American Stock Exchange trading policies; however, those shares will represent solely the right to receive the merger consideration of $19.50 per share.

        The transaction is valued at approximately $2 billion ($1.67 billion in equity and the assumption of approximately $750 million in indebtedness, less approximately $400 million in cash and cash equivalents). AMC expects to continue to operate under its current name. As a result of the acquisition, AMC will cease to be publicly traded and accordingly will no longer be listed on the American Stock Exchange after the market closes on December 23, 2004.

        AMC stockholders who have stock certificates in their own name will receive instructions by mail from UMB Bank, n.a., the exchange agent, concerning how and where to forward their certificates for payment.
