Interim report January 1 – March 31, 2006

Continued strong growth – Pointsec sales increased by 56% in the first quarter

FIRST QUARTER 2006 • Net sales increased by 41% to SEK 90.1 M (63.7) • Revenues from Pointsec sales increased by 56% to SEK 77.5 M • Profit after net financial items amounted to SEK 17.3 M (13.5) • Profit after tax amounted to SEK 11.2 M (8.8) • Earnings per share increased by 24% to SEK 0.99 (0.80) CEO Thomas Bill’s comments: “Our significant investments in sales and marketing functions continued to show favorable results. We want to leverage the exceptionally strong market trend. The sales increase for our proprietary Pointsec software was 56 percent during the first quarter of 2006, and our assessment is that Pointsec will continue to take market shares. Although profit increased, it was restrained somewhat by continued sales and marketing investments. The US and Asia, particularly Japan, continued to show strong growth. The partnership announced with HitachiSoft will further strengthen our position in the Japanese market. Sales were also strong in the Nordic countries and the UK during the quarter. On the other hand, development of the German market was unsatisfactory, causing us to strengthen our efforts in that area. Overall, Protect Data is in a strong position to take advantage of the positive market trend that we foresee continuing through the rest of the year, meaning that both sales and profit are expected to increase, compared with 2005.”
