WESTFORD, Mass.—(BUSINESS WIRE)—Jan. 22, 2004—Concerto Software, Inc. (NASDAQ: CRTO), a leading provider of customer interaction management (CIM) solutions, today announced its preliminary and unaudited financial results for the fourth quarter and full year of 2003, which ended December 31, 2003.

For the year ended December 31, 2003, Concerto Software expects total revenue of approximately $107.0 to $107.5 million, an increase of 7.5% to 8.0% over 2002 total revenue of $99.5 million. The company’s expectation for total revenue for 2003 was $107.8 million, as stated in its definitive proxy statement filed with the United States Securities and Exchange Commission (“SEC”), dated January 5, 2004. The company anticipates GAAP net income of approximately $2.3-$2.5 million, or $0.20-$0.22 diluted earnings per share, for the year ended December 31, 2003, compared with a GAAP net loss of $8.0 million or $0.66 diluted loss per share for the year ended December 31, 2002. The company’s expectation for net income for 2003 was $3.7 million, as indicated in its January 5, 2004 definitive proxy statement filed with the SEC, but such estimate did not include $1.1 million of pre-tax professional fees incurred related to the pending merger with Melita International, Ltd. (“Melita”), which represents $0.07 of diluted earnings per share.

For the fourth quarter of 2003, total revenue is expected to be approximately $27.8-$28.3 million, an increase of 7.3% to 9.3%, from $25.9 million in the same period in 2002 and an increase of 2.2% to 4.0% from $27.2 million for the third quarter of 2003. The company expects GAAP net income for the fourth quarter of 2003 to be approximately $0.3-$0.5 million or diluted earnings per share of $0.03-$0.05, compared to a GAAP net loss of $4.6 million or $0.39 diluted loss per share for the same period in 2002 and GAAP net income of $0.8 million or $0.07 diluted earnings per share for the third quarter of 2003. The company’s expectation for its fourth quarter net income for 2003 was $1.6 million, based upon its January 5, 2004 definitive proxy statement filed with the SEC, which estimate did not include the $0.8 million of pre-tax professional fees incurred in the fourth quarter related to the pending merger with Melita, which represents $0.05 of diluted earnings per share.

On January 5, 2004, Concerto Software filed a definitive proxy statement and an amended transaction statement on Schedule 13E-3 with the SEC relating to the proposed merger with Melita. The transaction is valued at approximately $145.2 million and all of Concerto Software’s outstanding shares will be purchased for $12.00 per share in cash, except for certain shares held by a director of the company, which will be exchanged for a minority interest in the surviving company. The stockholder vote to approve the merger is scheduled for February 6, 2004.
