Exhibit 99.1 FOR FURTHER INFORMATION: Media Relations Investor Relations Margaret Thomson Bill Henderson 859-815-3039 859-815-4494 mrthomson@ashland.com wehenderson@ashland.com FOR IMMEDIATE RELEASE AUGUST 29, 2003 ASHLAND COMPLETES SALE OF ELECTRONIC CHEMICALS BUSINESS GROUP Covington, Ky. - Ashland Inc. (NYSE:ASH) said today it has completed the sale of its Electronic Chemicals business group (ECD) to Air Products (NYSE:APD) in a cash transaction valued at approximately $300 million. The transaction is expected to produce net cash flow of roughly $260 million and an after-tax gain in the neighborhood of $80 million. The gain will be recorded in Ashland's fiscal fourth quarter, which ends September 30. "The sale is a reflection of our strategic repositioning," said Chairman and Chief Executive Officer James J. O'Brien. "In our ongoing review of assets, we concluded that we could not continue to compete effectively in electronic chemicals without making a major new investment. Yet electronic chemicals was not one of our core businesses. The best decision for our shareholders and for ECD was to sell this business group and put the assets to work elsewhere. In this case, we will use the proceeds to strengthen the balance sheet in pursuit of our goal to reduce debt to 35 percent of total capital."
