EXHIBIT 99.1 UPS SEES VOLUME DIVERSION AFFIRMS 2ND QUARTER GUIDANCE ATLANTA (BUSINESS WIRE) July 10, 2002 United Parcel Service (NYSE: UPS - - News) today reported progress at the bargaining table with the International Brotherhood of Teamsters, but said it was seeing diversion of package volume to competitors. The company reaffirmed its previous earnings guidance for the second quarter of $0.50 to $0.55 per diluted share. UPS will release its second quarter earnings on July 23. According to Chief Financial Officer Scott Davis, UPS's business began to show the effects of the unresolved labor negotiations in June. U.S. domestic volume levels in April and May were running approximately 2% below prior-year levels, consistent with the economy's general weakness. In June, the volume decline was 4%. As a result, U.S. domestic volume for the second quarter declined 2.6%. "We are grateful for the loyalty and confidence demonstrated by our customers," said Davis. "But we've said all along the risk of volume being diverted would increase the closer we got to contract expiration, and diversion will accelerate if there's no agreement soon. It's even more important the company and the union conclude these negotiations in a timely manner." The company said the Teamsters and UPS had made good progress over the past 48 hours of negotiations.
