WEBMD REPORTS SECOND QUARTER RESULTS

Revenue growth benefits from synergies between base business and acquired companies

ELMWOOD PARK, NJ (August 5, 2004) — WebMD Corporation (NASDAQ: HLTH) today announced financial results for the three months ended June 30, 2004.

Key Financial Highlights

Revenue for the second quarter was $281.9 million compared to $233.4 million a year ago, an increase of 20.8%. Income before taxes, non-cash and other items for the second quarter was $30.0 million or $0.09 per share compared to $30.1 million or $0.09 per share a year ago. Income from continuing operations for the second quarter was $5.8 million or $0.02 per share compared to income from continuing operations of $5.4 million or $0.02 per share a year ago. Net income for the second quarter was $5.8 million or $0.02 per share compared to a net loss of ($26.3) million or ($0.08) per share a year ago.

As of June 30, 2004, WebMD had approximately $800 million in cash, cash equivalents and long-term marketable debt securities.

“During the second quarter, we were encouraged by the revenue performance at WebMD Envoy, WebMD Health and Porex,” said Roger C. Holstein, CEO of WebMD Corporation. “Our revenue growth is beginning to benefit from the synergies between our base business and the acquired companies. Management is excited that key investment initiatives already underway should improve operating efficiency and help expand profit margins as we exit 2004.”

Segment Operating Results

WebMD Envoy revenues were $166.0 million for the second quarter compared to $118.0 million in the prior year, an increase of 40.7%. The $48.0 million increase in WebMD Envoy’s revenues includes $38.4 million of revenues from customers acquired in recent acquisitions. Income before taxes, non-cash and other items was $28.9 million compared to $22.3 million in the prior year. Operating margins declined primarily as a result of continuing costs related to our implementation efforts for HIPAA and higher transaction-related expenses, partially offset by higher operating margins of recent acquisitions. HIPAA and realignment expenses are expected to peak in the third quarter as WebMD Envoy substantially completes its remediation and integration efforts leading to expanded operating margins as it exits the year.

WebMD Practice Services revenues were $71.8 million for the second quarter compared to $76.8 million in the prior year. Income before taxes, non-cash and other items was $1.8 million compared to $6.4 million in the prior year. The results continue to be impacted by longer sales and installation cycles and lower system margins. However, as a result of key investments in customer service, information infrastructure and clinical software, WebMD Practice Services expects margins to expand in the second half of the year in a meaningful way.

WebMD Health revenues were $31.9 million for the second quarter compared to $26.5 million in the prior year, a gain of 20.0%, primarily driven by strong market acceptance of our promotional and educational programs. Income before taxes, non-cash and other items was $7.6 million compared to $6.2 million in the prior year.

Porex revenues were $20.7 million for the second quarter compared to $18.6 million in the prior year, an increase of 11.5%. Income before taxes, non-cash and other items was $6.3 million compared to $5.5 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.

“During the quarter, we have assumed a leadership role in bringing healthcare constituents together to ensure that HIPAA fulfills its promise of reducing healthcare administrative costs and increasing efficiency,” said Mr. Holstein. “In addition, the government’s proposal for transforming our healthcare system into a consumer-centric and information-rich system that connects providers, establishes electronic medical information records, and creates a portable consumer health record, rapidly aligns our business imperatives with public policy goals.”
