Segment Operating Results
Emdeon Business Services segment revenue was $201.2 million for the first quarter compared to $185.7 million in the prior year period, an increase of 8.3%. The increase in Emdeon Business Services revenue was attributable to strong performance in our remittance and payment, patient statement, provider and ViPS businesses and the impact of the January 8, 2006 US Postal Service rate increase. Segment Adjusted EBITDA was $43.2 million compared to $38.3 million in the prior year period, an increase of 12.9%. Operating margins increased to 21.5% compared to 20.6% a year ago primarily as a result of higher revenue and the continued achievement of operating efficiencies and cost savings.

Segment Adjusted EBITDA was $10.2 million compared to $4.4 million in the prior year period, an increase of 131.4%. Operating margins increased from 6% in the prior year period to 13.4% as a result of changes in revenue mix and improvements in our delivery and service infrastructure.

As previously announced on May 2, 2006, WebMD segment revenue was $50.1 million for the first quarter compared to $33.6 million in the prior year period, an increase of 49.1%, driven by continued growth in online services.
