Revenue

Full-year 2005 revenue totaled $292.2 million, versus $274.6 million in 2004. Increases of $19.1 million in consulting, $11.6 million in recurring software maintenance and $12.0 million of software hosting revenue more than offset the loss of $22.5 million of outsourced services revenue from exited businesses and contracts.

Non-recurring revenue represented 45.2% of total revenue in 2005, compared to 42.1% in 2004. This reflects primarily the significant improvement in non-recurring consulting revenue in 2005 and the loss of recurring hosting and business process outsourcing revenue from exited businesses and contracts.

New Business Bookings

For the full-year 2005, TriZetto signed 1,055 new customer contracts with a total value of $296.6 million, compared to $335.3 million in 2004. Contract bookings comprise a mix of current and future period revenue and represent the expected minimum total revenue to be generated under each contract. New contract bookings will vary from one quarter to the next. The company targets approximately $50 to $60 million of new contract bookings each quarter. In the fourth quarter ended December 31, 2005, TriZetto signed 237 new customer contracts with a total value of $83.1 million, compared to $58.8 million in the year-ago quarter.

Backlog

At December 31, 2005, the company's total revenue backlog was approximately $703 million, compared to $585 million at December 31, 2004 and $663 million at September 30, 2005. Twelve-month revenue backlog was approximately $185 million at December 31, 2005, compared to $173 million at December 31, 2004 and $194 million at September 30, 2005. The timing of contract closings and other factors can cause the company's backlog to vary from one quarter to the next.

Profitability

Full-year 2005 net income was $22.0 million, or $0.48 per diluted share, compared to net income of $8.5 million, or $0.18 per share, in 2004. Due to the company's Federal net operating loss (NOL) carry forwards, the year's tax provision represented an effective rate of approximately 5.4%, which was partially offset by prior year state refunds of $0.8 million. At year-end 2005, TriZetto had $102.7 million in NOL carry forwards. Adjusted EBITDA was $48.2 million, compared to $35.8 million in 2004.

TriZetto reports earnings in accordance with Generally Accepted Accounting Principles (GAAP), and additionally reports certain non-GAAP measures, such as Adjusted EBITDA, believing that these provide additional information for investors to evaluate the company's financial performance. A definition of Adjusted EBITDA and a reconciliation to GAAP measures are included in the attached financial schedules.

Gross margin for 2005 was 45.8%, compared to 38.2% in 2004. Recurring revenue gross margin increased to 42.0% in 2005 from 35.9% in 2004. Non-recurring revenue gross margin increased to 50.3% in 2005 from 41.5% in 2004. Gross margin for the fourth quarter of 2005 was 46.4%, compared to 42.2% in the year-ago period.

Research and development expenses represented 10.8% of revenue in 2005, slightly lower than the 11.1% in 2004. This reflected the company's continuing development investments in both enterprise and component software to add new capabilities and functionality for future customer needs. Selling, general and administrative expenses were 26.3% of revenue, compared to 21.8% in 2004. The increase was primarily due to investment in developing the company's market-facing structure, higher incentive compensation and higher outside services fees and expenses.

Cash Resources and Cash Flow

Cash, restricted cash and short-term investments totaled $108.5 million at December 31, 2005, versus $73.1 million at December 31, 2004 and $57.8 million at September 30, 2005.

Net cash provided by operating activities in 2005 was $43.8 million, compared to $35.8 million in 2004. Capital expenditures for the year were $17.2 million, at the low end of the company's guidance range, compared to $17.1 million in the prior year.

In the fourth quarter of 2005, the company received net cash proceeds of $82 million after deducting the amount used to repurchase 1 million shares of the company's common stock in connection with its convertible debt offering and transaction fees and expenses. The company used $35 million of cash during the quarter in connection with its acquisition of CareKey, Inc.

Days sales outstanding for the fourth quarter of 2005 was 61 days, versus 66 in the year-ago quarter.

Guidance for 2006 Includes SFAS 123R

For the full year 2006, TriZetto expects between $315 and $330 million of revenue, representing an 8% to 13% increase over 2005. TriZetto expects diluted EPS to be $0.52 to $0.60, which includes an estimated $0.10 to $0.14 per share negative impact for the effect of adopting Statement of Financial Accounting Standards No. 123R, which requires all companies to expense stock-based compensation for 2006. Adjusted EBITDA for 2006, which excludes stock-based compensation expense, is expected to be between $63 and $67 million, an increase of 31% to 39% over 2005 Adjusted EBITDA. Capital expenditures in 2006 are expected to be between $18 and $22 million. Diluted share count for 2006 is expected to be approximately 48 million.

For the first quarter of 2006, the company expects revenue of approximately $77 to $81 million, EPS of $0.11 to $0.14 on a diluted share count of approximately 47 million, and Adjusted EBITDA of $14 to $15 million.

TriZetto is focused on growing Adjusted EBITDA at a long-term targeted rate approaching 30% per year, while maintaining capital spending at approximately the company's current rate. TriZetto projects that organic revenue growth of 8% to 12% will be required to achieve this target, depending on the mix of sales.
