“As The Outcomes Company, Eclipsys is committed to helping healthcare providers improve how they manage their businesses in today’s financially challenging healthcare environment,” said R. Andrew Eckert, Eclipsys president and chief executive officer. “The acquisition of EPSi reinforces our commitment to the financial decision support space, and we look forward to building on our company’s leadership position in this market.”

Acquisition Enables Eclipsys to Immediately Deliver SQL-based Business Decision Support Solutions

Like Eclipsys’ clinical and access management solutions, EPSi’s solutions are based upon the Microsoft SQL platform. The applications are web-based, scalable, flexible and easy to implement - with documented, rapid return on investment. The addition of the EPSi product suite significantly accelerates Eclipsys’ timeline for delivering a SQL-based business decision support solution.

“Eclipsys and EPSi are a winning combination for our clients and the market, as both companies are committed to delivering clients real value and real results,” said Tim Rutledge, president of EPSi. “We are very excited to join the Eclipsys team and be able to provide our clients the benefits of the tremendous Eclipsys infrastructure and resources to continue our momentum, development and growth.”

EPSi’s management and employees are expected to continue with the business. Eckert stated, “EPSi has a very talented group of people who have built a successful business. We welcome them to Eclipsys and look forward to their ongoing contributions to the growth of this business and service to an expanding base of clients.”

Transaction Details

The acquisition of EPSi by Eclipsys closed on February 25, 2008. Eclipsys acquired all of the issued and outstanding capital stock of EPSi from its former stockholders for a purchase price of approximately $53 million payable in cash at closing, subject to certain holdback arrangements and working capital adjustments.

Guidance

Eclipsys previously provided Non-GAAP guidance on February 14, 2008. At that time Eclipsys expected 2008 revenues to range from $506 to $518 million, and Non-GAAP EPS to range from $0.98 to $1.02. As a result of the acquisition of EPSI, Eclipsys is updating its non-GAAP guidance for 2008. Eclipsys now expects 2008 revenues to range from $516 to $528 million and non-GAAP EPS to range from $1.02 -$1.06. This non-GAAP guidance excludes stock-based compensation expense, costs associated with our derivative litigation, and costs associated with corporate headquarters relocation as well as amortization of acquisition related intangible assets and purchase accounting adjustments.
