Pioneer-Standard Announces Closing of Offer to Purchase Senior Notes

CLEVELAND, Ohio – March 28, 2003 – Pioneer-Standard Electronics, Inc. (Nasdaq: PIOS) today announced that its previously announced tender offer to purchase for cash any and all of its outstanding 9.5% Senior Notes, at a price of $1,047.50 per $1,000 principal amount, closed at 5 p.m. on March 25, 2003. Valid tenders have been received with respect to approximately $19 million of Senior Notes, representing nearly 13 percent of the Notes outstanding.

On March 18, 2003, the Company provided revised guidance for charges related to restructuring and discontinued operations in its fiscal fourth quarter ended March 31, 2003, in the range of $55 million to $65 million. The guidance anticipated that 100 percent of its 9.5% Senior Notes would be tendered and the estimate included the premium that would have been paid to purchase these Notes. With only 13 percent of the Notes tendered, the Company is now reducing its estimate for charges related to restructuring and discontinued operations to between $50 million and $60 million for its fiscal fourth quarter.
