EMDEON ANNOUNCES PRELIMINARY FIRST QUARTER RESULTS

ELMWOOD PARK, NJ (May 3, 2007) — Emdeon Corporation (NASDAQ: HLTH) today announced preliminary financial results for the three months ended March 31, 2007.

Kevin Cameron, Chief Executive Officer of Emdeon, said: “I am very pleased with our results for the first quarter. Each of our business segments delivered strong results. WebMD, in particular, clearly demonstrated its continuing market leadership with growth in revenue and Adjusted EBITDA of 46% and 93%, respectively.”

Consolidated Financial Highlights

Revenue for the first quarter was $122.0 million. Earnings before interest, taxes, non-cash and other items (“Adjusted EBITDA”) for the first quarter was $17.2 million or $0.09 per share. Preliminary income from continuing operations for the first quarter was $6.1 million or $0.03 per share and preliminary net income was $6.0 million or $0.03 per share.

On November 16, 2006, Emdeon completed the sale of a 52% interest in its Emdeon Business Services segment (excluding the ViPS business) to an affiliate of General Atlantic LLC. The Company’s 48% portion of EBS’ income is reflected in the line item “Equity in earnings of EBS Master LLC” for the March 2007 quarter. For the prior year period, the results of Emdeon Business Services are included in the Company’s consolidated revenues and earnings. As a result, our consolidated results will not be comparable to the respective prior year periods until after the anniversary of the transaction is reached.

Emdeon has recently identified errors in non-cash income tax expense and related deferred tax liabilities which resulted in an understatement of non-cash income tax expense of a net amount estimated to be $4.0 million for prior periods. Emdeon has netted the deferred tax liability resulting from amortization of goodwill against deferred tax assets relating to Emdeon’s net operating loss carryforwards (NOL’s). Because the deferred tax liabilities have an indefinite life, they should not have been netted against deferred tax assets with a definite life. Emdeon is in the process of determining whether the correction of this error will be reflected in the results for the March 2007 quarter or will be reflected by amending its financial statements for prior periods. The preliminary results for the current and prior period as well as the financial guidance included with this release do not reflect the impact of the correction. The correction will not have any impact on revenue, Adjusted EBITDA or operating cash flows.

As of March 31, 2007, Emdeon had approximately $701 million in cash and short-term investments on a consolidated basis, including $212 million in cash and short-term investments held by WebMD Health Corp., its 84.3% owned subsidiary.

Segment Operating Results

WebMD segment revenue was $73.0 million for the first quarter compared to $50.1 million in the prior year period, an increase of 45.8%, driven by continued growth in online services. Segment Adjusted EBITDA was

$12.6 million compared to $6.5 million in the prior year period, an increase of 93.2% over the prior year, primarily as a result of the increase in revenues.

ViPS segment revenue was $26.7 million for the first quarter compared to $23.8 million in the prior year period, an increase of 11.8%. The increase was attributable to an increase in consulting services and license revenue. Segment Adjusted EBITDA was $4.8 million compared to $5.2 million in the prior year period, a decrease of 6.2%. Operating margins decreased slightly to 18.2% primarily as a result of revenue mix.

Porex segment revenue was $22.7 million for the first quarter compared to $20.6 million in the prior year period, an increase of 10.3%. The increase was primarily attributable to strength in sales of consumer products and favorable foreign currency exchange rates. Segment Adjusted EBITDA was $6.5 million compared to $5.6 million in the prior year period, an increase of 16.6%. Operating margins increased to 28.5% compared to 27.0% a year ago primarily as a result of the increase in revenues.

Investment in Emdeon Business Services

Revenue for Emdeon Business Services (which is not a segment and is not included in the Company’s consolidated revenue) was a record $198 million for the first quarter. Emdeon Business Services continues to generate strong year over year growth and we are pleased with its performance.
