Item 7.01. Regulation FD Disclosure.
On December 2, 2008, David P. Steiner, Chief Executive Officer and Robert G. Simpson, Chief Financial Officer of Waste Management, Inc. (the “Company”), are scheduled to make a presentation at 1:35 p.m. Eastern Standard Time at the 2008 Friedman Billings Ramsey Capital Markets Fall Investor Conference in New York City.
On October 30, 2008, the Company issued a press release and held a conference call to announce and discuss its third quarter 2008 earnings results. In that release and on the conference call, the Company stated that due to the downturn in the recycling commodities markets, the Company believed that its fourth quarter 2008 earnings per diluted share could be negatively impacted by up to $0.03 per share.
As noted in the slide deck that will be used for management’s presentation at the conference, a copy of which is furnished herewith as Exhibit 99.1 and incorporated by reference herein, the Company now expects the negative impact on its fourth quarter 2008 earnings per diluted share to be between $0.04 and $0.08 per share. The increase in the expected negative impact is due to the continued deterioration in the recycling commodities markets through the month of November, which showed prices decreasing at an average of 30 to 60% as compared with the prior year period, as well as forecasts of continued weakness in the markets. However, the extent of the actual negative impact will depend primarily on whether prices for recycling commodities stabilize or continue to deteriorate during the month of December.
You can listen to a webcast of the presentation by going to the Investor Relations section of the Company’s website at www.wm.com beginning on December 2, 2008.
