Exhibit 99.1 Daisytek Predicts Significant Earnings Contribution from ISA ALLEN, Texas--June 24, 2002-- Management Provides FY03 and FY04 Guidance; 50% Revenue Growth, 20% Net Income Rise Expected in '03 Daisytek International Corporation (Nasdaq:DZTK) today provided initial guidance on future earnings following the successful takeover of ISA International plc (London AIM: ISA.L). Daisytek's offer for ISA's ordinary share capital was declared successful on June 14. Management will discuss corporate prospects in greater detail, including analysis by fiscal quarter, in a conference call Tuesday at 9:30 a.m. CST, 10:30 a.m. EST. "We are confirming revenue estimates for this year ending March 31, 2003. Daisytek's targeted consolidated revenue is in the range of $1.8 billion to $1.9 billion, a growth of at least 50% from last year," said Jim Powell, president and CEO of Daisytek International. Daisytek is a global distributor of computer supplies, office products and accessories with operations in the United States, Canada, Mexico, Australia, South America and seven European countries as a result of the ISA deal. ISA is a U.K.-based distributor of computer supplies with operations in the United Kingdom, Ireland, France, Germany, Norway, Sweden and Italy. "Largely as a result of earnings dilution from ISA for the first two quarters of this fiscal year, we expect earnings per share for this fiscal year to be in the range of $1.05 to $1.10, based on a diluted, weighted average share count of 19.8 million shares and before any non-recurring charges. Corresponding net income this year will be about $21 million to $22 million, which is an increase of about 20% over last year's pro-forma $17.8 million," Powell said. "Based upon our expectations for ISA's continued recovery, we are targeting significant earnings growth to Daisytek for several years. We expect accretion from ISA to commence in our third fiscal quarter ending Dec. 31, 2002, and continue thereafter, including all four quarters of FY04. As a result, our early guidance for earnings in FY04 is $1.40 to $1.50 per diluted share. "Revenue growth should remain strong, with organic growth rates projected to be in the range of 10% to 15% annually. We will target ISA's operating profits to continue to improve to levels consistent with Daisytek's own. Last quarter, Daisytek's operating margins were 3.2% of revenue, with plans for its existing businesses to go to 3.5% in the next 12 months. We expect ISA to achieve this same level of improvement over the next three years, and as a result we anticipate consolidated earnings to rise 30% next year and 20% to 25% in the following two years, outstripping top-line growth rates," continued Powell. "The path to reaching these profit levels does not require extraordinary actions at ISA, nor realization of merger synergies. ISA has suffered from a lack of cash for the past two years. We are now recapitalizing the company and providing it with much-needed working capital. The three major country operations -- United Kingdom, France and Germany -- are operating from their own, new distribution centers with no significant investment required to achieve the targeted growth metrics. Daisytek is now one of the largest purchasers of computer supplies in the world and we will use our position to achieve supply chain improvements for ourselves and our business partners around the world, both customers and manufacturers," said Powell. "ISA is not only a great strategic fit with a great management team already in place, but it represents a significant earnings growth opportunity for Daisytek shareholders. In addition, we continue to see many opportunities in our existing businesses where computer supplies demand remains strong and our full entry into office products as an integrated service offering is on track for later this year," Powell concluded.
