Exhibit 99.1 [INSIGHT LOGO] ================================================================================ NASDAQ: NSIT FOR IMMEDIATE RELEASE WEDNESDAY, JULY 17, 2002 INSIGHT ENTERPRISES, INC. ANNOUNCES ANTICIPATED SECOND QUARTER 2002 RESULTS TEMPE, ARIZONA - JULY 17, 2002 - INSIGHT ENTERPRISES, INC. (NASDAQ: NSIT) (the "Company") today announced that it expects net sales for the second quarter of 2002 to be approximately $737 million compared to $505 million in the second quarter of 2001. Second quarter diluted earnings per share are expected to be between $0.26 and $0.29, compared to $0.26 in the same period last year. The Company previously stated that it expected net sales and diluted earnings per share to be between $720 million and $760 million and $0.31 and $0.35, respectively. These results reflect three acquisitions made by the Company during Q4 2001 and Q2 2002. The Company is a holding company with two operating units, Insight Direct Worldwide, Inc. ("Insight") and Direct Alliance Corporation. The disappointing Q2 2002 results are due to the operating results experienced by Insight's United Kingdom operations, which had operating losses in Q2 2002 compared to operating earnings in Q1 2002. It was not until the consolidation process that it was determined that actual results were substantially lower than expected. According to Timothy A. Crown, Chief Executive Officer, "Net sales in the United Kingdom declined from $113 million in Q1 2002 to $89 million in Q2 2002, or 21%. The decline in net sales occurred primarily in the large enterprise sector. Additionally, due to strong competitive pressures and reduced demand, the gross profit percentage in the United Kingdom for Q2 2002 was lower than expected." Mr. Crown continued, "Effective today, both the president and chief operating officer of Insight's United Kingdom operations have resigned and we have replaced them with other executives from the Company who will operate the business until permanent replacements are found." Additional information will be provided when the Company reports its second quarter results on July 25, 2002.
