Exhibit 99.1 FOR IMMEDIATE RELEASE Contact: James P. Kelly Director, Investor Relations (617) 342-6244 jim_kelly@cabot-corp.com CABOT CORPORATION ANNOUNCES RESOLUTION OF CONTRACT DISPUTE WITH VISHAY INTERTECHNOLOGY BOSTON, MA - (June 6, 2002) - Cabot Corporation (NYSE: CBT) today announced that it has resolved the pending legal dispute regarding its long-term tantalum supply contracts with Vishay Intertechnology, Inc. (NYSE: VSH) and its subsidiaries. In connection with the resolution of the dispute, the parties have entered into amended supply agreements that confirm Vishay's obligation to purchase tantalum products at regular intervals throughout the terms of the contracts, beginning immediately. In addition, subject to certain conditions, prices (starting in 2003) and volumes have been reduced, and the term of one of the supply contracts has been extended for one year. "We are very pleased to have resolved this dispute without further legal proceedings," said Kennett F. Burnes, Chairman and CEO of Cabot Corporation. Mr. Burnes went on to say, "The amended contracts will continue to provide substantial value to the Company while normalizing our commercial relationship with a significant and valued customer. Under the revised agreements, we currently expect this year's results from our Performance Materials business to be in the same range as its 2001 results. We remain optimistic about the stability of Cabot's tantalum business and are well prepared to supply all our customers' needs as the electronics industry recovers. While there is still some uncertainty, assuming that the industry conditions remain the same or improve, the business should show significant improvement, perhaps as much as 50%, from this level in fiscal 2003, although likely not to the levels previously indicated." The Company's contract dispute with one other customer continues. CABOT CORPORATION IS A GLOBAL SPECIALTY CHEMICALS AND MATERIALS COMPANY AND IS HEADQUARTERED IN BOSTON, MASSACHUSETTS.
