InfoVista Announces Preliminary Financial Results for the Fourth Quarter and Fiscal Year 2011

Regulatory News:

• Estimated revenue below objective
• Estimated operating margin in upper range of objective

InfoVista (Paris:IFV)(Euronext: IFV, ISIN: FR0004031649), a global leader of service performance assurance, today announced that it expects revenue for the fourth quarter and fiscal year 2011, to be approximately €11.4 million and €45.8 million, respectively, compared to its annual objective of €47 million. Therefore, total revenue growth was 7% for the fiscal year. Based on preliminary estimates, operating margin for fiscal year 2011 is expected to be approximately 9%, which is at the higher end of InfoVista’s 7% - 10% operating margin objective. As a result, operating income is expected to increase year-on-year by more than 65%.

Philippe Ozanian, InfoVista Chief Executive Officer, stated, "We ended our fiscal year slightly below our revenue objective and in the higher range of our operating margin objective. Over the past three years, we have significantly improved the productivity of our organization executing on our commitment to grow operating income. Our optimized sales organization targets high-value deals, which may result in lumpy quarters from time to time. This was evidenced in the fourth quarter where a few large deals did not come to closure. In fact one of these deals for approximately € 1 million was received in the first days of July and as of today we are finalizing its term and conditions to determine which portion of that deal could be recognizable in this September quarter. Despite the disappointment of not reaching our top line objective we remain confidence in our business particularly as our operating margin performance comforts us in our strategy to deliver strong financial results.”
