Company Generates Cash from Operations of $675 Million for Fourth

             Quarter and $2.54 Billion for Full Year 2006

HOUSTON--(BUSINESS WIRE)--Feb. 8, 2007--Waste Management, Inc. (NYSE:WMI) today announced financial results for its fourth quarter and for the year ended December 31, 2006. Revenues for the quarter were $3.28 billion compared with $3.37 billion in the year ago period. Net income for the quarter was $246 million, or $0.46 per diluted share, compared with $290 million, or $0.52 per diluted share, for the fourth quarter 2005.

For the full year 2006, the Company reported revenues of $13.36 billion compared with $13.07 billion in 2005. Net income for the year was $1.15 billion, or $2.10 per diluted share, compared with $1.18 billion, or $2.09 per diluted share for the year 2005.

The Company noted several items that impacted the results in the current and prior years' fourth quarters. Excluding these items, net income would have been $252 million, or $0.47 per diluted share, in the fourth quarter of 2006 compared with $255 million, or $0.46 per diluted share, in the prior year quarter. Income from operations as a percent of revenue, as adjusted for these items, increased 30 basis points to 15.4% in the current year's quarter compared with the prior year's quarter.(a) Results in the current quarter included:

    --  After tax charges of $24 million for asset impairments and
        unusual items due principally to a charge which resulted from
        the resolution of a buyer's claim regarding the value of
        assets sold in a year 2000 transaction and an asset impairment
        charge at a closed landfill; partially offset by gains from
        the divestiture of operations.

    --  An $18 million benefit in net income resulting primarily from
        favorable income tax audit settlements and an adjustment to
        deferred tax liabilities resulting from the reduction of our
        effective state tax rate.

    Results in the prior year quarter included:

    --  A $43 million reduction in income tax expense resulting
        primarily from favorable income tax audit settlements and an
        adjustment to deferred tax liabilities arising from the
        reduction in our effective state income tax rate.

    --  After-tax charges of $8 million related to asset impairments
        and unusual items due principally to an asset impairment
        charge at a landfill and the impairment of two software
        applications; partially offset by a gain from the divestiture
        of operations.

"Our solid performance in the fourth quarter completed an excellent year in which we exceeded our internal expectations for earnings growth, margin expansion, and free cash flow. In the fourth quarter, we again expanded our margins and generated higher net cash from operating activities," said David P. Steiner, Chief Executive Officer of Waste Management. "Our internal revenue growth from yield on base business increased 2.9% in the fourth quarter of this year, which indicates that our pricing excellence initiatives continue to positively impact our financial performance. We lowered our operating costs by $105 million, which contributed to the 140 basis point reduction in our operating costs as a percent of revenue.

"Our ability to generate strong free cash flow and return it to our shareholders remains a cornerstone of our financial objectives. We generated $675 million in net cash from operating activities and $212 million of free cash flow during the quarter. For the year, we produced over $2.5 billion in net cash from operating activities and over $1.4 billion of free cash flow. Our full year free cash flow exceeded the high end of our projection due mainly to strong operating earnings, improved working capital and lower than expected capital expenditures. In 2006, we returned to our shareholders over $1.5 billion in cash, which was comprised of share repurchases of $1.07 billion and cash dividends of $476 million."

Steiner continued, "Internal revenue growth due to volumes declined by 4.4% during the fourth quarter of 2006 due to the combination of lower hurricane clean-up volumes, 1.3 fewer workdays and lower non-core revenues in this year's quarter. Absent these three factors, internal revenue growth due to volumes fell by 1.5%. This volume loss occurred primarily in our collection lines of business, which was again driven by our strategy to price our services to achieve acceptable margins and returns on capital. This strategy continued to produce positive results during the fourth quarter as income from operations and margins increased in our commercial, industrial and residential collection lines of business."

    Key Highlights for the Fourth Quarter and the Full Year 2006

    --  Income from operations as a percent of revenue, adjusted for
        the divestitures, asset impairments and unusual items,
        restructuring and non-recurring charges noted in our quarterly
        earnings releases, was 15.5% for the full year 2006, a 130
        basis point improvement when compared with 2005 results on the
        same basis.

    --  Operating expenses declined by $105 million, or 4.7%, to $2.11
        billion in the fourth quarter of 2006. As a percent of
        revenue, operating expenses fell to 64.2% during the current
        year quarter, which is a 140 basis point improvement compared
        with the prior year quarter. For the full year 2006, operating
        expenses were 64.3% of revenue, which is a 170 basis point
        improvement when compared with 2005.

    --  Net cash provided by operating activities of $675 million in
        the quarter and $2.54 billion for the full year.

    --  Free cash flow of $212 million in the quarter and $1.45
        billion for the full year.

    --  Internal revenue growth on base business due to yield
        increased 2.9% for the fourth quarter of 2006. This excludes
        the impact of our fuel surcharge revenue, which declined 0.1%
        during the quarter. For the full year, internal revenue growth
        on base business due to yield increased 3.6%. This excludes
        the impact of our fuel surcharge revenue, which increased 0.9%
        for the full year 2006.

    --  Internal revenue growth from volumes decreased 4.4% for the
        fourth quarter of 2006. Fourth quarter 2005 revenue included
        approximately $50 million in hurricane clean-up work. This did
        not repeat in 2006 and caused 1.5% of the reduction in revenue
        due to volumes. The combination of 1.3 fewer workdays and
        lower non-core volumes contributed about $45 million, or 1.4%,
        to the decline. The remaining 1.5% decline in internal revenue
        growth from volumes was caused principally by lower volumes in
        all three collection lines of business, an expected result
        from our pricing excellence initiatives. For the full year
        2006, internal revenue growth from volumes decreased 1.4%.

    --  Divestitures net of acquisitions caused a 1.5% decline in
        revenues in the quarter. Through today, operations with over
        $325 million in annual revenue have been divested as part of
        the previously announced divestiture program.

    --  Capital expenditures of $547 million in the quarter and $1.37
        billion for the full year.

    --  $256 million returned to shareholders during the quarter,
        consisting of $138 million in common stock repurchases, or 3.5
        million shares, and $118 million in cash dividends. For the
        full year, repurchases of common stock totaled $1.07 billion,
        or nearly 31 million shares. Dividends paid totaled $476
        million for the full year. For the full year, we returned over
        $1.5 billion to shareholders.

    --  The effective tax rate in the quarter, adjusted for the
        non-recurring items noted above, was 29.6%.

Steiner continued, "We produced excellent financial results throughout 2006 and laid a foundation on which we will build during 2007. We remain committed to our financial goals of growing earnings, expanding our operating margins, increasing our return on invested capital, and generating strong free cash flow which we intend to return to our shareholders in the form of cash dividend payments and share repurchases. We will accomplish these objectives by leveraging the same operating strategies that we followed in 2006.

"We expect that our pricing excellence programs will continue to drive value across all of our lines of business and we are expanding our pricing initiatives at our landfills and transfer stations. We also expect our account profitability analysis to lead to improved pricing and cost management across the commercial segment of our collection business. We plan to continue to improve our performance in the areas of productivity, maintenance and safety, with a goal of lowering our operating costs as a percent of revenue. We have plans to deploy our new revenue management system, an investment that is expected to improve the long-term performance of the Company. We will also continue to divest underperforming or non-strategic businesses.

"We enter 2007 amidst an economic environment that is showing modest growth but at a slower pace than we saw in 2006. We expect economic growth to accelerate in the last half of 2007. And as we saw in 2006, we project that our internal revenue growth will be driven by our pricing excellence initiatives. Along with operational improvements and divestitures, we expect this will lead to a significant expansion in our income from operations as a percent of revenue during 2007. As a result, we expect to grow our full-year earnings per diluted share by approximately 8 to 10% during 2007, or within a range of $1.96 to $2.00, when compared to our full-year 2006 results of $1.81 per diluted share as adjusted for the non-recurring items noted in our press releases."

2007 Outlook

The Company also announced the following in regard to its financial outlook for 2007:

    --  Income from operations as a percent of revenue projected to
        increase over 100 basis points, with selling, general and
        administrative expenses increasing due to higher expenses
        related to the implementation of our new revenue management
        system, process improvement initiatives and our long-term
        incentive plan; offset by continued operating cost
        improvements and internal revenue growth from yield in excess
        of CPI.

    --  Free cash flow projected to be within a range of $1.3 to $1.4
        billion. Capital expenditures expected to be within a range of
        $1.25 to $1.35 billion.

    --  Expected payment of $0.96 per share in dividends over the
        course of the year, at an approximate cash cost of $510
        million. Projected share repurchases of up to $690 million.
        Due to our expected free cash flow in 2007 and strong year-end
        2006 cash balances and short-term investments, up to an
        additional $700 million may be allocated to the retirement of
        debt, acquisition or other business opportunities, or
        additional share repurchases.

(a) This earnings release contains net income, earnings per share, income from operations as a percentage of revenue and effective tax rate, each as adjusted to exclude the impact of certain unusual, non-recurring or otherwise non-operational items. These are non-GAAP measures as defined in Regulation G of the Securities Exchange Act of 1934, as amended, and are not intended to replace the most comparable GAAP measures that are also presented in this press release. The Company reports its financial results in compliance with GAAP, but believes that also providing non-GAAP measures provides investors additional, meaningful comparisons of current results to prior periods' results by excluding items that the Company does not believe reflect its fundamental business performance. The Company also discloses its free cash flow and free cash flow forecast, which are non-GAAP measures. The Company defines free cash flow as:

    -- Net cash provided by operating activities

    -- Less, capital expenditures

-- Plus, proceeds from divestitures of businesses, net of cash divested, and other sales of assets.

The Company's definition of free cash flow may not be comparable to similarly titled measures presented by other companies, and therefore not subject to comparison. The Company includes the non-GAAP financial measure of free cash flow in its disclosures because it uses that measure in the management of its business and because it believes that investors are interested in the cash produced by the Company from non-financing activities that is available for uses such as the Company's acquisitions, its share repurchase program, its scheduled debt reduction and the payment of dividends.

Quantitative reconciliations of each of the non-GAAP measures presented herein to the most comparable GAAP measures are included in the accompanying schedules. Investors are urged to take into account GAAP measures as well as non-GAAP measures in evaluating the Company.

The Company, from time to time, provides estimates of financial and other data, comments on expectations relating to future periods and makes statements of opinion, view or belief about current and future events. Statements relating to future events and performance are "forward-looking statements." The forward-looking statements that the Company makes are the Company's expectations, opinion, view or belief at the point in time of issuance but may change at some future point in time. By issuing estimates or making statements based on current expectations, opinions, views or beliefs, the Company has no obligation, and is not undertaking any obligation, to update such estimates or statements or to provide any other information relating to such estimates or statements. Outlined below are some of the risks that the Company faces and that could affect our financial statements for 2007 and beyond and that could cause actual results to be materially different from those that may be set forth in forward-looking statements made by the Company. However, they are not the only risks that the Company faces. There may be additional risks that we do not presently know or that we currently believe are immaterial which could also impair our business. We caution you not to place undue reliance on any forward-looking statements, which speak only as of their dates. The following are some of the risks that we face:

    --  competition may negatively affect our profitability or cash
        flows, our price increases may have negative effects on
        volumes and price roll-backs and lower than average pricing to
        retain and attract customers may negatively affect our yield
        on base business;

    --  we may be unable to maintain or expand margins if we are
        unable to control costs;

    --  we may not be able to successfully execute or continue our
        operational or other margin improvement plans and programs,
        including pricing increases, passing on increased costs to our
        customers, and divesting under-performing assets and
        purchasing accretive businesses, any of which could negatively
        affect our revenues and margins;

    --  weather conditions cause our quarter-to-quarter results to
        fluctuate, and extremely harsh weather or natural disasters
        may cause us to temporarily shut down operations;

    --  inflation and resulting higher interest rates as well as other
        general and local economic conditions may negatively affect
        the volumes of waste generated, our financing costs and other
        expenses;

    --  possible changes in our estimates of site remediation
        requirements, final capping, closure and post-closure
        obligations, compliance and regulatory developments may
        increase our expenses;

    --  regulations may negatively impact our business by, among other
        things, restricting our operations, increasing costs of
        operations or requiring additional capital expenditures;

    --  if we are unable to obtain and maintain permits needed to
        open, operate, and/or expand our facilities, our results of
        operations will be negatively impacted;

    --  limitations or bans on disposal or transportation of
        out-of-state or cross-border waste or certain categories of
        waste can increase our expenses and reduce our revenues;

    --  fuel price increases or fuel supply shortages may increase our
        expenses, including our tax expense if Section 45K credits are
        phased out due to continued high crude oil prices, or restrict
        our ability to operate;

    --  increased costs to obtain financial assurance or the
        inadequacy of our insurance coverages could negatively impact
        our liquidity and increase our liabilities;

    --  possible charges as a result of shut-down operations,
        uncompleted development or expansion projects or other events
        may negatively affect earnings;

    --  fluctuating commodity prices may have negative effects on our
        operating revenues and expenses;

    --  trends requiring recycling, waste reduction at the source and
        prohibiting the disposal of certain types of wastes could have
        negative effects on volumes of waste going to landfills and
        waste-to-energy facilities;

    --  efforts by labor unions to organize our employees may increase
        operating expenses and we may be unable to negotiate
        acceptable collective bargaining agreements with those who
        have been chosen to be represented by unions, which could lead
        to union-initiated work stoppages, including strikes, which
        could adversely affect our results of operations and cash
        flows;

    --  negative outcomes of litigation or threatened litigation or
        governmental proceedings may increase our costs, limit our
        ability to conduct or expand our operations, or limit our
        ability to execute our business plans and strategies;

    --  problems with the operation of our current information
        technology or the development and deployment of new
        information systems may decrease our efficiencies and increase
        our costs to operate;

    --  the adoption of new accounting standards or interpretations
        may cause fluctuations in reported quarterly results of
        operations or adversely impact our reported results of
        operations; and

    --  we may reduce or eliminate our dividend or share repurchase
        program or we may need to raise additional capital if cash
        flows are less than we expect or capital expenditures are more
        than we expect, and we may not be able to obtain any needed
        capital on acceptable terms.

Additional information regarding these and/or other factors that could materially affect results and the accuracy of the forward-looking statements contained herein may be found in Part I, Item 1 of the Company's Annual Report on Form 10-K for the year ended December 31, 2005.

(a)The quarters ended December 31, 2006, September 30, 2006, and
    December 31, 2005 include short-term investments available for use
    of $184 million, $332 million, and $300 million, respectively.

(b)The quarter ended December 31, 2006, as compared to the quarter
    ended September 30, 2006, reflects a reduction in amortization
    expense of $10.3 million due to seasonal reduction in landfill
    volumes. Additionally, there was a reduction of $6.4 million in
    amortization expense in the fourth quarter 2006, primarily due to
    changes in final capping estimates resulting from our annual
    landfill review process.

(c)Reflected in the December 31, 2005 results is a reduction in
    landfill amortization expense of $12.4 million. This reduction
    relates primarily to adjustments to our fully accrued landfill
    final capping obligations and are a result of fourth quarter
    event-driven changes as well as changes in certain estimates
    resulting from our annual landfill review process.
