Following its Voluntary Delisting from NASDAQ in February 2007, InfoVista SA Announces its Deregistration from the SEC

InfoVista (Euronext: IFV, ISIN: FR0004031649), the leading service-centric performance management software company, today filed a Form 15F with the U.S. Securities and Exchange Commission (‘SEC’) to deregister its shares and terminate its reporting obligations under the U.S. Securities Exchange Act of 1934 (‘Exchange Act’). InfoVista’s obligations under the Exchange Act are suspended as from today. Under SEC rules, the deregistration will become effective 90 days after the filing unless there is an objection from the SEC. InfoVista plans to continue to post an English-language version of its annual report, financial statements and similar communications on its website, http://www.infovista.com.

InfoVista had previously voluntarily terminated its listing on the NASDAQ Global Market as of February 20, 2007. As announced on February 9, 2007, InfoVista’s decision to delist from NASDAQ and to deregister from the SEC is based on the low trading volume of its ADSs and the increasingly high cost of maintaining dual listings on NASDAQ and the Paris Euronext stock markets. The decision does not reflect any change in InfoVista’s commitment to its operations, customers or strategic development in the United States.
