(g) · Volumes in the Collection and Disposal business grew 0.2% as compared to the third quarter of 2024, driven by strong landfill volumes and growth in industrial collection volumes. This growth was partially offset by a decline in residential collection volumes due to the strategic exit of lower-margin contracts. · A revenue decline of $60 million in the Recycling Processing and Sales segment was driven by lower market prices for recycled commodities. The Company’s blended average price for single stream commodities declined nearly 35% from the prior year quarter. (h) · WM Healthcare Solutions revenue was slightly below expectations. The Company is taking a disciplined approach to customer engagement and prioritizing customer lifetime value, resulting in the deferral of some planned price increases.

(a) Cash Flow and Investments · Through the first nine months of the year, the Company generated $4.35 billion of net cash provided by operating activities, an increase of 12.0% from the prior year. This growth has been driven by strong operating EBITDA and a decline in cash taxes. These increases were partially offset by higher cash interest, which is due to the debt funding of the Stericycle acquisition. · Free cash flow in the first nine months of the year was $2.11 billion, a 13.5% year-over-year increase, driven by robust operating EBITDA growth and a planned reduction in capital investment in sustainability growth projects as the Company moves from peak construction of this portfolio into a period of harvesting strong returns on these businesses. These increases in free cash flow were partially offset by higher capital expenditures to support the business, which includes the addition of WM Healthcare Solutions. (a) · The Company’s leverage ratio continues to improve sequentially, driven by increased operating EBITDA and debt repayments. The Company remains on track to achieve its targeted leverage ratio of between 2.5 and 3.0 times by the middle of 2026. (i) Sustainability and WM Healthcare Solutions Update · The Company continues to progress its strategic investments in recycling and renewable natural gas facilities that drive economic and environmental value. During the quarter, four growth projects commenced operations, including new renewable natural gas facilities in Texas and California, a new recycling facility in Texas, and a recycling automation project in California. These additions bring total renewable natural gas projects completed to 10 out of the original 20 planned facilities and total recycling automation and new market projects completed to 31 out of the original 39 planned. · During the quarter, the Company progressed its integration of the people and operations of WM Healthcare Solutions into the management and operating structure of its 16 geographic areas, advancing process optimization and alignment across the business. 2025 Outlook The Company is confident in its ability to deliver upon its full-year outlook ranges for adjusted operating EBITDA and free cash flow. · The Company is affirming its adjusted operating EBITDA guidance of between $7.475 and $7.625 billion. (a) · Free cash flow guidance remains between $2.8 and $2.9 billion. (a) · Total Company revenue is now expected to be approximately $25.275 billion, which is at the low end of the Company’s prior guidance range. The decrease from prior expectations is primarily related to a further decline in recycled commodity pricing as well as modestly lower revenue expectations from WM Healthcare Solutions. (h) · Projected adjusted operating EBITDA margin guidance has increased to between 29.6% and 30.2% from between 29.6% and 29.9% . (a) Fish concluded, “We are pleased with our results in the first three quarters of the year across our business segments, which position us to deliver another year of double-digit adjusted operating EBITDA growth with record margin in our Collection and Disposal business and expanding free cash flow conversion. Looking ahead, 2026 is setting up to be a year of outsized free cash flow growth, with results expected to approach $3.8 billion next year. Our disciplined approach to capital allocation remains unchanged, and we are committed to translating this performance into strong shareholder returns.” (a) (a) The information labeled as adjusted in this press release, as well as free cash flow, are non-GAAP measures. Please see “Non-GAAP Financial Measures” below and the reconciliations in the accompanying schedules for more information. (b) Management defines operating EBITDA as GAAP income from operations before depreciation, depletion and amortization; this measure may not be comparable to similarly titled measures reported by other companies. (c) For purposes of this press release, all references to “Net income” refer to the financial statement line item “Net income attributable to Waste Management, Inc.” (d) All dollar amounts, unless otherwise noted, are presented in millions and rounded to the nearest million. Percentages are calculated using rounded figures and shown to one decimal place. Accordingly, percentage totals and subtotals may not sum to 100% due to rounding. (e) Management defines WM Legacy Business as total Company GAAP results excluding the WM Healthcare Solutions segment. (f) WM Healthcare Solutions includes intra-segment activity, with operating revenues and expenses of $108 million for the three months ended September 30, 2025. Inter-segment activity includes operating revenues of $2 million and operating expenses of $16 million for the same period. (g) Core price is a performance metric used by management to evaluate the effectiveness of our pricing strategies; it is not derived from our financial statements and may not be comparable to measures presented by other companies. Core price is based on certain historical assumptions, which may differ from actual results, to allow for comparability between reporting periods and to reveal trends in results over time. (h) The Company’s blended average price received for single stream recycled commodities sold during the quarter was about $68 per ton compared to about $101 per ton in the prior year period. The Company now expects single stream commodity prices to average approximately $75 per ton in 2025, which is down from its prior expectation of $80 per ton. The average price received for Renewable Fuel Standard credits was $2.56 during the quarter compared to $3.08 in the prior year period. The average price received for natural gas was $2.46 per MMBtu during the quarter compared to $1.80 per MMBtu in the prior year period. The average price received for renewable electricity was about $73 per megawatt hour in the quarter compared to about $60 per megawatt hour in the prior year period. (i) Leverage ratio is calculated based on the defined terms for this financial covenant in the Company’s revolving credit agreement, which is Exhibit 10.9 to the Company’s Form 10-K filed Feb. 19, 2025.

Please also see the Company’s filings with the SEC, including Part I, Item 1A of the Company’s most recently filed Annual Report on Form 10-K, as updated by subsequent Quarterly Reports on Form 10-Q, for additional information regarding these and other risks and uncertainties applicable to its business. The Company assumes no obligation to update any forward-looking statement, including financial estimates and forecasts, whether as a result of future events, circumstances or developments or otherwise. Non-GAAP Financial Measures To supplement its financial information, the Company has presented, and/or may discuss on the conference call, adjusted measures including adjusted earnings per diluted share, adjusted net income, adjusted income from operations and margin, adjusted operating EBITDA and margin, adjusted operating expense and margin, and adjusted SG&A expenses and margin. All adjusted measures and free cash flow are non-GAAP financial measures, as defined in Regulation G of the Securities Exchange Act of 1934, as amended. The Company reports its financial results in compliance with GAAP but believes that also discussing non-GAAP measures provides investors with (i) financial measures the Company uses in the management of its business and (ii) additional, meaningful comparisons of current results to prior periods’ results by excluding items that the Company does not believe reflect its fundamental business performance and are not representative or indicative of its results of operations. In addition, the Company’s projected adjusted operating EBITDA and margin is anticipated to be adjusted to exclude the effects of other events or circumstances that are not representative or indicative of the Company’s results of operations. Such excluded items are not currently determinable, but may be significant, such as asset impairments and one-time items, charges, gains or losses from divestitures or litigation, and other items. Due to the uncertainty of the likelihood, amount and timing of any such items, the Company does not have information available to provide a quantitative reconciliation of such projection to the comparable GAAP measure. The Company discusses free cash flow and provides a projection of free cash flow because the Company believes that it is indicative of its ability to pay its quarterly dividends, repurchase common stock, fund acquisitions and other investments and, in the absence of refinancings, to repay its debt obligations. The Company believes free cash flow gives investors useful insight into how the Company views its liquidity, but the use of free cash flow as a liquidity measure has material limitations because it excludes certain expenditures that are required or that the Company has committed to, such as declared dividend payments and debt service requirements. The Company defines free cash flow as net cash provided by operating activities, less capital expenditures, plus proceeds from divestitures of businesses and other assets (net of cash divested); this definition may not be comparable to similarly-titled measures reported by other companies. The quantitative reconciliations of non-GAAP measures to the most comparable GAAP measures are included in the accompanying schedules, with the exception of projected adjusted operating EBITDA and margin, and projected 2026 free cash flow. Non-GAAP measures should not be considered a substitute for financial measures presented in accordance with GAAP.

SUPPLEMENTAL INFORMATION PROVIDED FOR ILLUSTRATIVE PURPOSES ONLY (In Millions) (Unaudited) Diversity in the structure of recycling contracts results in different accounting treatment for commodity rebates. In accordance with revenue recognition guidance, our Company records gross recycling revenue and records rebates paid to customers as cost of goods sold. Other contract structures allow for netting of rebates against revenue. Additionally, there are differences in whether companies adjust for accretion expense in their calculation of EBITDA. Our Company does not adjust for landfill accretion expenses when calculating operating EBITDA, while other companies do adjust it for the calculation of their EBITDA measure. The table below illustrates the impact that differing contract structures and treatment of accretion expense has on the Company’s adjusted operating EBITDA margin results. This information has been provided to enhance comparability and is not intended to replace or adjust GAAP reported results.
