SANTA CLARA, Calif., October 27, 2005—WebEx Communications, Inc. (Nasdaq: WEBX) today announced financial results for the third quarter ended September 30, 2005.

Revenue
For the third quarter of 2005, revenue was $78.6 million, a 23% increase from $64.0 million in the third quarter of 2004. Revenue included $0.7 million from the company’s Intranets.com subsidiary after closing of its acquisition on September 9, 2005.

GAAP Earnings
Net income was $12.7 million for the third quarter of 2005, a 7% increase from $11.8 million for the third quarter of 2004. Diluted earnings per share were $0.26 per share even with $0.26 in the third quarter of 2004.

Non-GAAP Earnings
Net income on a non-GAAP basis was $13.1 million for the third quarter of 2005, or $0.27 per diluted share, compared to $11.8 million, or $0.26 per diluted share, in the comparable period last year. Non-GAAP EPS exclude expenses associated with the acquisition of Intranets.com, such as the effects of amortization of intangible assets, certain employee compensation and in-process research and development.

Cash
Cash and short-term investments at quarter end were approximately $194.8 million, after payment of $40 million cash (net of cash acquired) for the purchase of Intranets.com. Cash flow from operations was $17.6 million, partially offset by $4.4 million of capital expenditures, yielding a free cash flow of $13.2 million for the three months ended September 30, 2005. During the third quarter of 2005, WebEx spent approximately $7.9 million as part of its stock buyback program, repurchasing approximately 304,000 shares of common stock. Under the currently authorized stock buyback program of $40 million, WebEx has spent approximately $26 million to date, while approximately $14 million remains available for future stock repurchases.

“I am pleased to report that we had the strongest new order booking quarter in the history of WebEx. We believe this demonstrates that the named-user flat rate pricing option is generating increased demand for our collaborative web applications,” said Subrah Iyar chairman and chief executive officer of WebEx. “Within one month of the acquisition of Intranets.com, we also delivered new integrated products to the market and significantly expanded our application suite to extend our leadership in software as a service delivery.”

Guidance
The following contains forward-looking guidance regarding WebEx’s financial outlook. The following statements are based on current expectations.

For the fourth quarter of 2005, WebEx anticipates revenues in the range of $81.0 to $83.5 million and GAAP EPS in the range of $0.26 to $0.28 and Non-GAAP EPS in the range of $0.27 to $0.29. Non-GAAP EPS exclude expenses associated with the acquisition of Intranets.com, including the effects of amortization of intangible assets and certain employee compensation.

For fiscal year 2006, revenue is anticipated to be in the range of $370 to $385 million. For fiscal year 2006, anticipated GAAP EPS will be provided later due to change in accounting standards regarding expensing equity based compensation that becomes effective in 2006.

Non-GAAP Financial Measures
This press release includes financial measures for earnings per share and net income for our results for the third quarter of 2005 and guidance for the fourth quarter of 2005 that have not been calculated in accordance with generally accepted accounting principles (GAAP). These differ from GAAP in that they exclude expenses associated with the acquisition of Intranets.com, including the effects of amortization of intangible assets, certain employee compensation, and in-process research and development. WebEx believes that providing these non-GAAP financial measurements is useful to its investors because they provide a consistent basis for comparison of WebEx’s financial condition and results of operations between quarters, which comparison is not influenced by acquisition related expenses associated with the purchase of Intranets.com. The presentation of this additional information is not meant to be considered in isolation or as a substitute for earnings per share or net income calculated in accordance with GAAP. A reconciliation of these GAAP and non-GAAP financial measures is included in the attached tables.
