The Best Quarter Ever Yet

InfoVista’s two main regions, Europe and North America, produced record fourth quarter revenues resulting in strong top-line growth for both the quarter and the full fiscal year. Despite the weaker dollar, InfoVista’s American operations generated impressive year-on-year sales growth in euro terms, with large contracts won in a highly competitive environment.

• In the fourth quarter, North America, Europe and Asia contributed 50%, 42% and 8%, respectively, to total revenues. American and European operations achieved quarterly revenue growth of 30% and 14%, year-on-year respectively. The growth in Asia-Pacific revenues picked up pace in the quarter, with sales of €0.7 million. Two large deals totaling US$1.0 million were won in India with the two major local Service Providers, one of whom is Bharti Tele-Ventures Ltd. Revenue for these two deals is expected to be recognized in fiscal year 2006. • InfoVista made deep inroads into the Enterprise arena, with revenues significantly increasing to €4.1 million, and contributing 43% to total revenues for the quarter. The Company closed a deal of over €1 million with one of the world’s largest financial institutions. Service Provider revenues stood at €5.5 million, representing 57% of total revenues for the quarter with business from American, Spanish and Singaporean incumbents. New Service Provider customers included Jazz Telecom and Spirit Telecom. • Q4 repeat business from existing customers represented 72% of total revenues. Repeat customers during the quarter included MCI Worldcom in the US, Telefonica and France Télécom in Europe, and Optus in Australia. • Revenues from Software Licenses for the fourth quarter grew by 22% year-on-year and represent 58% of total revenues. Service Revenues increased by 15% to €4.0 million. • Revenues from indirect sales channels contributed 34% of total revenues for the fourth quarter, while direct sales channels, including revenues from referral partners, contributed the remaining 66% or €6.3 million.

Remarkable Year of Turnaround and Achievements

Mr. Tobaly said: “IP convergence of voice, data and video is driving tremendous opportunities and challenges for our customers. We are ideally positioned to capitalize on this exciting market transformation, helping our clients harness the power that these next-generation communication services can offer.”

During the fiscal year, the Company launched three major solutions:

• VistaInsight for IP Telephony allows customers to manage the complexity and reap the promised benefits of telephony services delivered over IP. The solution was launched in February 2005 and has been recognized by market experts as far surpassing competitive offerings. • VistaInsight for Networks empowers Service Providers to maximize the performance of their MPLS-based networks and offer highly differentiated web-based customer reporting. • VistaInsight for Server Management helps large customers better manage their system resources providing advanced performance and capacity planning capabilities.

The Company also announced major innovations of its technical platform, VistaFoundation, which dramatically reduces cost of ownership of the communications infrastructure especially in very large and distributed environments. All these technical breakthroughs accentuate InfoVista’s position as the leading provider of solutions for the management of next-generation communication services.

During the fiscal year, the Company cemented its leadership position in the Service Provider segment, becoming the performance management standard in the telecommunications industry. Additionally, InfoVista made great strides in the Enterprise segment, securing large wins particularly in the financial industry.

• Europe, North America and Asia contributed 48%, 44% and 8% of total fiscal year revenues, respectively. European revenues were up 20% over last year to €16.5 million. Revenues in North America amounted to €15.2 million, representing 26% year-on-year growth. • For the fiscal year, Enterprise revenues amounted to €9.7 million or 28% of total revenues, with Service Providers generating the remaining 72% of the year’s revenues. • Repeat business from existing customers represented 80% of the fiscal year’s total revenues. • Revenues from Software Licenses contributed 55% of the year’s revenues, up 18%. Service Revenues grew by 21%. • Revenues from indirect channels contributed 38% to total revenues for fiscal year 2005, while direct channels including revenues from referral partners contributed the remaining 62%.

Outlook

Looking ahead, Mr. Tobaly commented: “I am confident that the momentum will continue into the new fiscal year and we anticipate organic growth of approximately 20% for fiscal year 2006. For the first quarter, despite traditional unfavorable seasonality, particularly in Europe, we expect total revenues of between €8.7 million and €9.2 million, a revenue growth of about 20% over the same period last year.”

In accordance with SFAS (Statement of Financial Accounting Standards) 123(R), the Company will commence accounting for stock based compensation in its results of operations in fiscal year 2006. InfoVista anticipates a charge of approximately €1.1 million for stock compensation in fiscal year 2006 and approximately €310,000 for its first quarter. As such, InfoVista expects negative net results for the first quarter but positive net income for the entire fiscal year.
