EXHIBIT 99.1 (WASTE MANAGEMENT LOGO) FOR IMMEDIATE RELEASE FOR FURTHER INFORMATION: WASTE MANAGEMENT, INC. ANALYSTS: CHERIE RICE 713.512.6548 MEDIA: SARAH SIMPSON 713.394.2154 WMI#03-16 WASTE MANAGEMENT ANNOUNCES SIGNIFICANT INCREASE IN DIVIDEND AND CHANGE TO A QUARTERLY PAYMENT SCHEDULE PER SHARE DIVIDEND TO INCREASE FROM $0.01 TO $0.75 PER YEAR QUARTERLY DIVIDEND PAYMENT OF $0.1875 TO BEGIN IN THE FIRST QUARTER 2004 HOUSTON - AUGUST 5, 2003 - The Board of Directors of Waste Management, Inc. (NYSE: WMI) today announced the approval of a quarterly dividend program, to begin in the first quarter 2004. "This company is first and foremost a big cash flow generator," said A. Maurice Myers, Chairman, President and Chief Executive Officer of Waste Management. "The Board of Directors and management of Waste Management consider the allocation of our cash flow, to the benefit of our shareholders, to be one of our most important duties. With the passage of the new tax law regarding dividends, we felt a change in the allocation of capital is now appropriate. "Accordingly, beginning in 2004 we are putting in place a capital allocation program designed to pay our shareholders a dividend of $0.75 per share annually, to be paid on a quarterly basis. Based on current share count, this equates to nearly $450 million. At the current share price of approximately $24.00, such a dividend produces a 3.1% annual yield. Our substantial cash flow will also provide for a continuation of our stock buy back program, at a level to be determined annually and for the acquisition of selected core, North American solid waste assets that meet our return criteria," Myers said. "This reallocation of the distribution of our free cash flow demonstrates our confidence in the strength and consistency of our cash flow and is a continuation of the Company's disciplined management of its capital with our shareholders' interests as our top priority, and balanced by our commitment to maintaining a strong balance sheet," added Myers. The Company noted that it intends to announce the record and payment dates for the first quarterly dividend in late January, with the expectation that payment of the dividend will occur in March. Waste Management, Inc. is its industry's leading provider of comprehensive waste management services. Based in Houston, the Company serves municipal, commercial, industrial, and residential customers throughout North America.
