Agreements

WebMD Announces Third Quarter Earnings Release Date and Conference Call

NEW YORK, NY (October 16, 2007) — WebMD Health Corp. (Nasdaq: WBMD), the leading provider of health information services, today announced preliminary financial results for the three months ended September 30, 2007.

Preliminary Results for the Three Months Ended September 30, 2007

WebMD expects that it will report the following financial results for the third quarter of 2007:

• Revenue of $86.0 to $87.0 million, an increase of approximately 30% over the $66.6 million reported in the prior year period. Prior guidance was $89.0 to $94.0 million.

• Earnings before interest, taxes, depreciation, amortization, and other non-cash items (“Adjusted EBITDA”) of $22.8 to $23.8 million, an increase of approximately 59% over the $14.6 million reported in the prior year period. Prior guidance was $22.0 to $24.5 million.

• Net income of $10.8 to $11.7 million as compared to $0.5 million reported in the prior year period. Prior guidance was $8.2 to $10.6 million.

Traffic to The WebMD Health Network was approximately 40 million average monthly unique visitors and 860 million page views, an increase of 24% and 18%, respectively, over the prior year. Excluding the prior year period’s traffic from AOL (which ceased to be part of The WebMD Health Network earlier this year), the average monthly unique visitors to The WebMD Health Network increased approximately 32% and page view traffic increased approximately 22%.

“We continued to experience strong sales growth of advertising and sponsorship programs in the pharmaceutical, bio-tech and medical device markets this past quarter. However, the timing of the launch of these programs is more weighted to 2008 than we had expected. Additionally, as we have previously discussed, we have been experiencing a lengthened sales and implementation cycle in our private portals business. Our Adjusted EBITDA continues to demonstrate that we are realizing the benefits of our investments in infrastructure improvements,” said Wayne Gattinella, President and CEO of WebMD.

The above information is preliminary. WebMD is completing its normal closing process and will provide third quarter financial results and revised financial guidance for the fourth quarter on November 7, 2007.

WebMD and Yahoo! Sign Exclusive Multi-Year Search and Advertising Distribution Agreements

In a separate release today, WebMD and Yahoo! Inc. announced that they had entered into exclusive, multi-year search and advertising distribution agreements. Under the new agreements, WebMD will extend its advertising reach to include WebMD users across Yahoo! properties and services. WebMD will be the only significant online health publisher to represent Yahoo!’s advertising inventory. In addition, Yahoo! will power sponsored search across the WebMD network of consumer sites, including WebMD Health, MedicineNet, eMedicine Health and RxList.

“These strategic agreements, which dramatically extend WebMD’s ability to uniquely reach health-involved consumers across the breadth of both WebMD and Yahoo! properties, will create incremental revenue opportunities for us,” said Wayne Gattinella, President and CEO of WebMD. “We’re pleased to bring Yahoo’s world class sponsored search capability to WebMD users as they seek credible health information on our network of consumer sites.”
