WEBMD REPORTS FIRST QUARTER RESULTS

ELMWOOD PARK, NJ (May 6, 2004) — WebMD Corporation (NASDAQ: HLTH) today announced financial results for the three months ended March 31, 2004.

Key Financial Highlights
Revenue for the first quarter was $271.2 million compared to $221.5 million a year ago, an increase of 22.4%. Income before taxes, non-cash and other items for the first quarter was $28.2 million or $0.09 per share compared to $28.8 million or $0.10 per share a year ago. Income from continuing operations for the first quarter was $5.7 million or $0.02 per share compared to a loss from continuing operations of ($8.8) million or ($0.03) per share a year ago. Net income for the first quarter was $5.7 million or $0.02 per share compared to a net loss of ($7.4) million or ($0.02) per share a year ago.

As of March 31, 2004, WebMD had approximately $846 million in cash and short and long-term marketable debt securities.

Roger C. Holstein, CEO of WebMD, stated, “As we entered 2004, we expected that the industry challenges and our own company challenges would be great but that the opportunity would be even greater. In the first quarter, we saw results consistent with or slightly better than our expectations at WebMD Envoy, WebMD Health and Porex, offsetting a disappointing quarter at WebMD Practice Services. Although our company-wide investments in talent and technology will be seen in the expense line in the short-term, we believe these investments will yield revenue growth and margin expansion in the future.”

Segment Operating Results
WebMD Envoy revenues were $163.8 million for the first quarter compared to $115.5 million in the prior year. The $48.3 million increase in WebMD Envoy’s revenues includes $39.8 million of revenues from customers acquired in recent acquisitions. Income before taxes, non-cash and other items was $29.9 million compared to $24.1 million in the prior year. Operating margins declined primarily as a result of increased costs related to our implementation efforts for HIPAA and our all-payer service and higher transaction-related sales expenses, partially offset by higher operating margins of recent acquisitions.

WebMD Practice Services revenues were $71.0 million for the first quarter compared to $72.0 million in the prior year. Revenues, particularly in the month of March, were impacted by lower system sales resulting from longer and more complex sales cycles and HIPAA and other transition challenges related to Network Services product offerings. Income before taxes, non-cash and other items was $1.4 million compared to $6.3 million in the prior year, reflecting the lower system sales and the continued spending necessary to support our all-payer network services infrastructure.

WebMD Health revenues were $26.3 million for the first quarter compared to $22.2 million in the prior year, driven by strong market acceptance of our pharmaceutical, medical device and employer-sponsored programs. Income before taxes, non-cash and other items was $4.5 million compared to $4.0 million in the prior year.

Porex revenues were $18.4 million for the first quarter compared to $17.3 million in the prior year. Income before taxes, non-cash and other items was $5.0 million compared to $4.7 million in the prior year. These

results do not include the revenues or earnings from the two Porex operating units which were divested on August 1, 2003.

Financial Guidance
In a Form 8-K furnished to the Securities and Exchange Commission today, WebMD provided modified financial guidance. Consolidated revenue and earnings guidance remains unchanged. However, the relative contribution of each business segment has been adjusted.
