Advent Software Announces Stock Repurchase Program

San Francisco, CA, May 18, 2004 - Advent Software, Inc. (NASDAQ: ADVS) announced today that its board of directors has approved a stock repurchase program in which up to 1,200,000 shares of its Common Stock may be repurchased in the open market from time to time. As of May 17, 2004, Advent had approximately 33.1 million shares outstanding.

The number of shares to be repurchased and the timing of purchases will be based on several factors, including the price of Advent Software’s stock, general market conditions and alternative investment opportunities. The purchases will be funded from available working capital.

Stephanie DiMarco, chief executive officer, stated that “the decision was made in view of the prices at which the Company’s common stock has recently traded, which we believe does not reflect the true long-term value of the Company. In addition, the repurchase program will also offset dilution from stock issued under our employee stock plans.”
