Financial Guidance

On July 24, 2012, the Company reduced its financial guidance for 2012. A copy of the schedule issued on July 24^th outlining WebMD’s 2012 financial guidance is attached to this press release. The Company anticipates that many of its customers will continue to reevaluate expenditures in various areas, including marketing expenditures across their entire product portfolios, as they deal with both the ongoing and anticipated impact of patent expirations across their businesses as well as greater than expected delays in new product launches as a result of unanticipated delays in FDA approvals. The Company lowered its expectations for sales commitments and revenue for the balance of 2012 as these factors are having a greater impact than anticipated in its previous financial guidance.

“When I look at the many stakeholders in the healthcare industry and the changing market environment, I strongly believe that there are many opportunities we can capitalize on with the WebMD brand and the broad reach and high quality of WebMD’s unique physician and consumer audience,” said Cavan M. Redmond, Chief Executive Officer of WebMD. “My immediate priority is to set and operationalize our go-to-market strategy focusing on our current and future commercial offerings, capital allocation, talent needs and cost structure.”
