NEWPORT BEACH, Calif. – January 14, 2005 – The TriZetto Group, Inc. (Nasdaq:TZIX) today announced its initial guidance for 2005 of approximately $280 million in revenue, $43 to $45 million of EBITDA1, $0.26 to $0.32 earnings per share (EPS) and $20 to $24 million of free cash flow2. The company also reconfirmed its previous guidance for 2004 EPS of $0.12 to $0.17. Management anticipates announcing final audited results for 2004 on February 11, 2005.

"TriZetto's success in 2004 was driven by operational improvements in our sales processes as well as in every business unit," said Jeff Margolis, TriZetto's Chairman and CEO. "We have been systematically replacing lower-margin business lines from our portfolio with higher-margin new products and services while significantly reducing our cost structure. Our 2005 guidance builds on these business improvements and reflects our continuing emphasis on margin expansion, earnings and cash flow growth." Kathleen Earley, TriZetto's President and COO added, "We will continue to refine and invest in our leading portfolio of products and services and are focusing our energies on the highest-demand areas that position our customers to win in consumer directed healthcare, care management, direct electronic connectivity, managed Medicare and managed Medicaid."

For the full year 2005, TriZetto expects to generate approximately $280 million in revenue, representing 12% growth from an adjusted continuing operations revenue base of approximately $250 million. The continuing operations revenue base reflects the loss of a large customer that was acquired, a health plan customer that shut down and other 2004 revenue from certain lines of business the company chose to exit in 2004. Revenue from new sales is expected to contribute, on average, higher margins than exited businesses. The company anticipates generating between $43 and $45 million of EBITDA, and between $0.26 and $0.32 of EPS, on a diluted share count of approximately 45 million. This represents a 53% to 167% increase over 2004 EPS expectations. Capital expenditures in 2005 are expected to be between $18 and $20 million. "We anticipate generating $20 to $24 million of free cash flow in 2005," added CFO Jim Malone.

For the first quarter of 2005, which reflects some seasonality in revenue mix and costs, the company expects revenue of approximately $62 to $67 million, between $8 and $10 million of EBITDA, and between $0.00 and $0.05 of EPS on a diluted share count of approximately 44 million.

The company is evaluating the timing and effects of adopting Statement of Financial Accounting Standards No. 123 (revised 2004), Share-Based Payment, which affects accounting for stock options and other forms of stock-based compensation. This revised statement was issued in December 2004 and is effective July 1, 2005. The company's guidance for 2005 does not reflect the effect of applying the new accounting rules.
