Segment and Related Information

7. Segment and Related Information

Our senior management evaluates, oversees and manages the financial performance of our Solid Waste operations through two operating segments. Our East Tier primarily consists of geographic areas located in the Eastern U.S., the Great Lakes region and substantially all of Canada. Our West Tier primarily includes geographic areas located in the Western U.S., including the upper Midwest region, and British Columbia, Canada. Each of our Solid Waste operating segments provides integrated environmental services, including collection, transfer, recycling, and disposal. The East and West Tiers are presented in this report and constitute our existing Solid Waste business.

The operating segments not evaluated and overseen through our East and West Tiers are presented herein as “Other” as these operating segments do not meet the criteria to be aggregated with other operating segments and do not meet the quantitative criteria to be separately reported and are not qualitatively significant at this time.

Summarized financial information concerning our reportable segments is shown in the following table (in millions):

(a)

Income from operations provided by our Solid Waste business is generally indicative of the margins provided by our collection, landfill, transfer and recycling lines of business and includes elements of profitability from our “Other” segment. From time to time, the operating results of our reportable segments are significantly affected by certain transactions or events that management believes are not indicative or representative of our results.

Income from operations in our Solid Waste business increased primarily due to revenue growth in our collection and disposal business driven by yield. These increases were partially offset by (i) inflationary cost pressures; (ii) labor cost increases from frontline employee wage adjustments and annual merit increases and (iii) reduced profitability in our recycling business from the decline in recycling commodity prices. In addition, fuel tax credits in 2022 were not recognized until August 2022 due to the timing of the Inflation Reduction Act of 2022 (“IRA”). This created a $26 million negative impact to income from operations for the three months ended September 30, 2023, but is broadly flat for the nine months ended September 30, 2023.

(b)

“Other” includes (i) elements of our Strategic Business Solutions (“WMSBS”) business that are not included in the operations of our reportable segments; (ii) elements of our sustainability business that includes landfill gas-to-energy operations managed by our WM Renewable Energy business, our Sustainability and Environmental Solutions business and recycling brokerage services and not included in the operations of our reportable segments; (iii) certain other expanded service offerings and solutions and (iv) the results of non-operating entities that provide financial assurance and self-insurance support for our Solid Waste business, net of intercompany activity.

The decrease in income from operations was due to (i) reduced profitability in our WM Renewable Energy business primarily driven by decreases in the value of energy prices and renewable fuel standard credits and (ii) the decline in recycling brokerage commodity prices affecting profitability in our recycling business.

(c)

“Corporate and Other” operating results reflect certain costs incurred for various support services that are not allocated to our reportable segments. These support services include, among other things, treasury, legal, digital, tax, insurance, centralized service center processes, other administrative functions and the maintenance of our closed landfills.

Income from operations for “Corporate and Other” also includes costs associated with our long-term incentive program.

The improvement in income from operations was primarily driven by (i) lower annual incentive compensation costs; (ii) lower professional fees in connection with investments in our digital program, as certain strategic projects have now been implemented and (iii) a charge during the first quarter of 2022 to adjust an indirect wholly-owned subsidiary’s estimated potential share of the liability for a proposed environmental remediation plan at a closed site. These lower costs were partially offset by annual merit increases and litigation costs.

(d)	Intercompany operating revenues reflect each segment’s total intercompany sales, including intercompany sales within a segment and between segments. Transactions within and between segments are generally made on a basis intended to reflect the market value of the service.

The mix of operating revenues from our major lines of business are as follows (in millions):

Total	$	5,198	$	5,075	$	15,209	$	14,763

(a)

The “Other” line of business includes (i) certain services provided by our WMSBS business; (ii) certain services within our sustainability business including our landfill gas-to-energy operations managed by our WM Renewable Energy business; (iii) certain other expanded service offerings and solutions and (iv) the results of non-operating entities that provide financial assurance and self-insurance support for our Solid Waste business, net of intercompany activity. Revenue attributable to collection, landfill, transfer and recycling services provided by our “Other” businesses has been reflected as a component of the relevant line of business for purposes of presentation in this table.

(b)	Intercompany revenues between lines of business are eliminated in the Condensed Consolidated Financial Statements included within this report.

Fluctuations in our operating results may be caused by many factors, including period-to-period changes in the relative contribution of revenue by each line of business, changes in commodity prices and general economic conditions. Our revenues and income from operations typically reflect seasonal patterns. Our operating revenues tend to be somewhat higher in summer months, primarily due to the higher construction and demolition waste volumes. The volumes of industrial and residential waste in certain regions where we operate also tend to increase during the summer months. Our second and third quarter revenues and results of operations typically reflect these seasonal trends.

Service or operational disruptions caused by severe storms, extended periods of inclement weather or climate events can significantly affect the operating results of the geographic areas affected. Extreme weather events may also lead to supply chain disruption and delayed project development, or disruption of our customers’ businesses, reducing the amount of waste generated by their operations.

Conversely, certain destructive weather and climate conditions, such as wildfires in the Western U.S. and hurricanes that most often impact our operations in the Southern and Eastern U.S. during the second half of the year, can increase our revenues in the geographic areas affected as a result of the waste volumes generated by these events. While weather-related and other event-driven special projects can boost revenues through additional work for a limited time, due to significant start-up costs and other factors, such revenue can generate earnings at comparatively lower margins.

Debt Classification

As of September 30, 2023, we had approximately $2.4 billion of debt maturing within the next 12 months, including (i) $489 million of short-term borrowings under our commercial paper program (net of related discount on issuance); (ii) $1.6 billion of tax-exempt bonds with term interest rate periods that expire within the next 12 months, which is prior to their scheduled maturities; (iii) $156 million of 3.5% senior notes that mature in May 2024 and (iv) $174 million of other debt with scheduled maturities within the next 12 months, including $60 million of tax-exempt bonds. As of September 30, 2023, we have classified $2.1 billion of debt maturing in the next 12 months as long-term because we have the intent and ability to refinance these borrowings on a long-term basis as supported by the forecasted available capacity under our $3.5 billion long-term U.S. and Canadian revolving credit facility (“$3.5 billion revolving credit facility”), as discussed below. The remaining $297 million of debt maturing in the next 12 months is classified as current obligations.

Access to and Utilization of Credit Facilities, Commercial Paper Program and Term Loan

$3.5 Billion Revolving Credit Facility — Our $3.5 billion revolving credit facility, maturing May 2027, provides us with credit capacity to be used for cash borrowings, to support letters of credit and to support our commercial paper program. The interest rates we pay on outstanding U.S. or Canadian loans are based on the Secured Overnight Financing Rate (“SOFR”) administered by the Federal Reserve Bank of New York or the Canadian Dollar Offered Rate (“CDOR”), respectively, plus a spread depending on WMI’s senior public debt rating assigned by Moody’s Investors Service, Inc. and Standard and Poor’s Global Ratings. As of September 30, 2023, we had no outstanding borrowings under this facility. We had $181 million of letters of credit issued and $489 million of outstanding borrowings (net of related discount on issuance) under our commercial paper program, both supported by the facility, leaving unused and available credit capacity of

$2.8 billion as of September 30, 2023. WM Holdings, a wholly-owned subsidiary of WMI, guarantees all the obligations under the $3.5 billion revolving credit facility.

Commercial Paper Program — We have a commercial paper program that enables us to borrow funds for up to 397 days at competitive interest rates. The rates we pay for outstanding borrowings are based on the term of the notes. The commercial paper program is fully supported by our $3.5 billion revolving credit facility. As of September 30, 2023, we had $489 million of outstanding borrowings (net of related discount on issuance) under our commercial paper program.

Term Loan — In May 2022, we entered into our $1.0 billion, two-year, U.S. term credit agreement maturing May 2024 (“Term Loan”) to support general corporate purposes. WM Holdings guaranteed all obligations under the Term Loan. The interest rate we paid on our Term Loan was generally based on SOFR, plus a spread depending on WMI’s senior public debt rating assigned by Moody’s Investors Service, Inc. and Standard and Poor’s Global Ratings. The Term Loan had a contractual maturity of May 2024, but we elected to repay all outstanding balances under the Term Loan in August 2023 with proceeds from our July 2023 senior notes issuance, which is discussed further below.

Other Letter of Credit Lines — As of September 30, 2023, we had utilized $801 million of other uncommitted letter of credit lines with terms maturing through December 2026.

Debt Borrowings and Repayments

Commercial Paper Program — During the nine months ended September 30, 2023, we made cash repayments of $15.3 billion, which were partially offset by $14.1 billion of cash borrowings (net of related discount on issuance). A portion of these borrowings were repaid with proceeds from senior note issuances as discussed below.

Senior Notes — In February 2023, WMI issued $750 million and $500 million of 4.625% senior notes due February 2030 and February 2033, respectively, the net proceeds of which were $1.24 billion. We used the net proceeds to reduce outstanding borrowings under our commercial paper program, repay $500 million of WMI’s 2.4% senior notes upon maturity in May 2023, and for general corporate purposes, including our sustainability capital investment program.

In July 2023, WMI issued $750 million and $1.25 billion of 4.875% senior notes due February 2029 and February 2034, respectively, the net proceeds of which were $1.97 billion. We used the net proceeds to reduce outstanding borrowings under our commercial paper program, repay $1.0 billion of outstanding borrowings under our Term Loan and for general corporate purposes.

Term Loan — In August 2023, we repaid $1.0 billion of outstanding borrowings under our Term Loan with proceeds from our July 2023 senior notes issuance discussed above and contemporaneously terminated the facility.

Tax-Exempt Bonds — We issued $50 million of tax-exempt bonds during the nine months ended September 30, 2023. The proceeds from the issuance of these bonds were deposited directly into a restricted trust fund to be used for the specific purpose for which the money was raised, which is generally to finance expenditures for solid waste disposal facility, material recovery facility and renewable natural gas facility construction and development. In 2023, we also repaid $65 million of our tax-exempt bonds with available cash at their scheduled maturities.

Financing Leases and Other — The decrease in our financing leases and other debt obligations during the nine months ended September 30, 2023 is due to $91 million of cash repayments of debt at maturity, partially offset by an increase of $78 million primarily related to non-cash financing leases.

Interest Rate Derivatives

During 2023, we entered into treasury rate locks with a total notional value of $800 million to secure underlying interest rates associated with our senior notes issuances discussed above. We designated our treasury rate locks as cash flow hedges. These treasury rate locks were terminated contemporaneously with the related issuances of senior notes and we received cash of $19 million to settle the related assets.

- Definition

The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.

Variable Interest Entities

Variable Interest Entities

13. Variable Interest Entities

The following is a description of our financial interests in unconsolidated and consolidated variable interest entities that we consider significant:

Low-Income Housing Properties

We do not consolidate our investments in entities established to manage low-income housing properties because we are not the primary beneficiary of these entities as we do not have the power to individually direct the activities of these entities. Accordingly, we account for these investments under the equity method of accounting. Our aggregate investment balance in these entities was $278 million and $321 million as of September 30, 2023 and December 31, 2022, respectively. The debt balance related to our investments in low-income housing properties was $243 million and $295 million as of September 30, 2023 and December 31, 2022, respectively. Additional information related to these investments is discussed in Note 4.

Trust Funds for Final Capping, Closure, Post-Closure or Environmental Remediation Obligations

Unconsolidated Variable Interest Entities — Trust funds that are established for both the benefit of the Company and the host community in which we operate are not consolidated because we are not the primary beneficiary of these entities as (i) we do not have the power to direct the significant activities of the trusts or (ii) power over the trusts’ significant activities is shared. Our interests in these trusts are accounted for as investments in unconsolidated entities and receivables. These amounts are recorded in other receivables, investments in unconsolidated entities and long-term other assets in our Condensed Consolidated Balance Sheets, as appropriate. We also reflect our share of the unrealized gains and losses on available-for-sale securities held by these trusts as a component of our accumulated other comprehensive (loss) income. Our investments and receivables related to these trusts had an aggregate carrying value of $94 million and $93 million as of September 30, 2023 and December 31, 2022, respectively.

Consolidated Variable Interest Entities — Trust funds for which we are the sole beneficiary are consolidated because we are the primary beneficiary. These trust funds are recorded in restricted funds in our Condensed Consolidated Balance Sheets. Unrealized gains and losses on available-for-sale securities held by these trusts are recorded as a component of accumulated other comprehensive income (loss). These trusts had a fair value of $116 million and $113 million as of September 30, 2023 and December 31, 2022, respectively.

Common Stock Repurchase Program

Common Stock Repurchase Program

11. Common Stock Repurchase Program

The Company repurchases shares of its common stock as part of capital allocation programs authorized by our Board of Directors.

In the first quarter of 2023, we entered into an accelerated share repurchase (“ASR”) agreement to repurchase $350 million of our common stock. At the beginning of the repurchase period, we delivered $350 million cash and received 1.9 million shares based on a stock price of $150.34. The ASR agreement completed in May 2023 and we received 0.4 million additional shares based on a final weighted average price of $153.90.

In the second quarter of 2023, we entered into an ASR agreement to repurchase $250 million of our common stock and received 1.5 million shares based on a final weighted average stock price of $163.62. Subsequent to the completion of the ASR, we repurchased 0.1 million shares of our common stock in open market transactions in compliance with Rule 10b5-1 and Rule 10b-18 of the Exchange Act for $22 million, inclusive of per-share commissions, at a weighted average price of $164.79, of which $2 million was paid in July 2023.

In the third quarter of 2023, we entered into an ASR agreement to repurchase $350 million of our common stock and received 2.2 million shares based on a final weighted average stock price of $156.87. Additionally, we repurchased 0.1 million shares of our common stock in open market transactions in compliance with Rule 10b5-1 and Rule 10b-18 of the Exchange Act for $19.5 million, inclusive of per-share commissions, at a weighted average price of $168.04, of which $1.5 million was paid in October 2023.

The Inflation Reduction Act of 2022 (“IRA”), which was enacted into law on August 16, 2022, imposed a nondeductible 1% excise tax on the net value of certain stock repurchases made after December 31, 2022. We reflected the applicable excise tax in treasury stock as part of the cost basis of the stock repurchased. The discussion of our common stock repurchase program above is exclusive of the 1% excise tax.

As of September 30, 2023, the Company has authorization for $508.5 million of future share repurchases, exclusive of the 1% excise tax discussed above. Any future share repurchases pursuant to this authorization of our Board of Directors will be made at the discretion of management and will depend on factors similar to those considered by the Board of Directors in making dividend declarations, including our net earnings, financial condition and cash required for future business plans, growth and acquisitions.

Commitments and Contingencies

6. Commitments and Contingencies

Financial Instruments — We have obtained letters of credit, surety bonds and insurance policies and have established trust funds and issued financial guarantees to support tax-exempt bonds, contracts, performance of landfill final capping, closure and post-closure requirements, environmental remediation and other obligations. Letters of credit generally are supported by our $3.5 billion revolving credit facility and other credit lines established for that purpose. These facilities are discussed further in Note 3. Surety bonds and insurance policies are supported by (i) a diverse group of third-party surety and insurance companies; (ii) an entity in which we have a noncontrolling financial interest or (iii) a wholly-owned insurance captive, the sole business of which is to issue surety bonds and/or insurance policies on our behalf.

Management does not expect that any claims against or draws on these instruments would have a material adverse effect on our financial condition, results of operations or cash flows. We have not experienced any unmanageable difficulty in obtaining the required financial assurance instruments for our current operations. In an ongoing effort to mitigate risks of future cost increases and reductions in available capacity, we continue to evaluate various options to access cost-effective sources of financial assurance.

Insurance — We carry insurance coverage for protection of our assets and operations from certain risks including general liability, automobile liability, workers’ compensation, real and personal property, directors’ and officers’ liability, pollution legal liability, cyber incident liability and other coverages we believe are customary to the industry. Our exposure to loss for insurance claims is generally limited to the per incident deductible under the related insurance policy and any amounts that exceed our insured limits. Our exposure could increase if our insurers are unable to meet their commitments on a timely basis.

We have retained a significant portion of the risks related to our health and welfare, general liability, automobile liability and workers’ compensation claims programs. “General liability” refers to the self-insured portion of specific third-party claims made against us that may be covered under our commercial general liability insurance policy. For our self-insured portions, the exposure for unpaid claims and associated expenses, including incurred but not reported losses, is based on an actuarial valuation or internal estimates. The accruals for these liabilities could be revised if future

occurrences or loss development significantly differ from such valuations and estimates. We use a wholly-owned insurance captive to insure the deductibles for our general liability, automobile liability and workers’ compensation claims programs.

We do not expect the impact of any known casualty, property, environmental or other contingency to have a material impact on our financial condition, results of operations or cash flows.

Guarantees — In the ordinary course of our business, WMI and WM Holdings enter into guarantee agreements associated with their subsidiaries’ operations. Additionally, WMI and WM Holdings have each guaranteed all of the senior debt of the other entity. No additional liabilities have been recorded for these intercompany guarantees because all of the underlying obligations are reflected in our Condensed Consolidated Balance Sheets.

As of September 30, 2023, we have guaranteed the obligations and certain performance requirements of third parties in connection with both consolidated and unconsolidated entities, including guarantees to cover the difference, if any, between the sale value and the guaranteed market or contractually-determined value of certain homeowner’s properties that are adjacent to or near 19 of our landfills. We have also agreed to indemnify certain third-party purchasers against liabilities associated with divested operations prior to such sale. We do not believe that the remaining contingent obligations will have a material adverse effect on the Company’s business, financial condition, results of operations or cash flows.

Environmental Matters — A significant portion of our operating costs and capital expenditures could be characterized as costs of environmental protection. The nature of our operations, particularly with respect to the construction, operation and maintenance of our landfills, subjects us to an array of laws and regulations relating to the protection of the environment. Under current laws and regulations, we may have liabilities for environmental damage caused by our operations, or for damage caused by conditions that existed before we acquired a site. In addition to remediation activity required by state or local authorities, such liabilities include potentially responsible party (“PRP”) investigations. The costs associated with these liabilities can include settlements, certain legal and consultant fees, as well as incremental internal and external costs directly associated with site investigation and clean-up.

Estimating our degree of responsibility for remediation is inherently difficult. We recognize and accrue for an estimated remediation liability when we determine that such liability is both probable and reasonably estimable. Determining the method and ultimate cost of remediation requires that a number of assumptions be made. There can sometimes be a range of reasonable estimates of the costs associated with the likely site remediation alternatives identified in the environmental impact investigation. In these cases, we use the amount within the range that is our best estimate. If no amount within a range appears to be a better estimate than any other, we use the amount that is the low end of such range. If we used the high ends of such ranges, our aggregate potential liability would be approximately $120 million higher than the $185 million recorded in the Condensed Consolidated Balance Sheet as of September 30, 2023. Our ultimate responsibility may differ materially from current estimates. It is possible that technological, regulatory or enforcement developments, the results of environmental studies, the inability to identify other PRPs, the inability of other PRPs to contribute to the settlements of such liabilities, or other factors could require us to record additional liabilities. Our ongoing review of our remediation liabilities, in light of relevant internal and external facts and circumstances, could result in revisions to our accruals that could cause upward or downward adjustments to our balance sheet and income from operations. These adjustments could be material in any given period.

As of September 30, 2023, we have been notified by the government that we are a PRP in connection with 73 locations listed on the Environmental Protection Agency’s (“EPA’s”) Superfund National Priorities List (“NPL”). Of the 73 sites at which claims have been made against us, 14 are sites we own. Each of the NPL sites we own was initially developed by others as a landfill disposal facility. At each of these facilities, we are working in conjunction with the government to characterize or remediate identified site problems, and we have either agreed with other legally liable parties on an arrangement for sharing the costs of remediation or are working toward a cost-sharing agreement. We generally expect to receive any amounts due from other participating parties at or near the time that we make the remedial expenditures. The

other 59 NPL sites, which we do not own, are at various procedural stages under the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended, known as CERCLA or Superfund.

The majority of proceedings involving NPL sites that we do not own are based on allegations that certain of our subsidiaries (or their predecessors) transported hazardous substances to the sites, often prior to our acquisition of these subsidiaries. CERCLA generally provides for liability for those parties owning, operating, transporting to or disposing at the sites. Proceedings arising under Superfund typically involve numerous waste generators and other waste transportation and disposal companies and seek to allocate or recover costs associated with site investigation and remediation, which costs could be substantial and could have a material adverse effect on our consolidated financial statements. At some of the sites at which we have been identified as a PRP, our liability is well defined as a consequence of a governmental decision and an agreement among liable parties as to the share each will pay for implementing that remedy. At other sites, where no remedy has been selected or the liable parties have been unable to agree on an appropriate allocation, our future costs are uncertain.

On October 11, 2017, the EPA issued its Record of Decision (“ROD”) with respect to the previously proposed remediation plan for the San Jacinto River Waste Pits Site in Harris County, Texas. McGinnes Industrial Maintenance Corporation (“MIMC”), a subsidiary of Waste Management of Texas, Inc., operated some of the waste pits from 1965 to 1966 and has been named as a site PRP. In 1998, WMI acquired the stock of the parent entity of MIMC. MIMC has been working with the EPA and other named PRPs as the process of addressing the site proceeds. On April 9, 2018, MIMC and International Paper Company entered into an Administrative Order on Consent agreement with the EPA to develop a remedial design for the EPA’s proposed remedy for the site, and we recorded a liability for MIMC’s estimated potential share of the EPA’s proposed remedy and related costs, although allocation of responsibility among the PRPs for the proposed remedy has not been established. MIMC and International Paper Company have continued to work on a remedial design to support the EPA’s proposed remedy; however, design investigations indicate that fundamental changes are required to the proposed remedy and MIMC maintains its prior position that the remedy set forth in the ROD is not the best solution to protect the environment and public health. Due to further increases in the estimated cost of the remedy set forth in the ROD, we recorded an additional liability of $17 million as of March 31, 2022 for MIMC’s estimated potential share of such costs. As of September 30, 2023 and December 31, 2022, the recorded liability for MIMC’s estimated potential share of the EPA’s proposed remedy was $68 million. MIMC’s ultimate liability could be materially different from current estimates and MIMC will continue to engage the EPA regarding its proposed remedy.

Item 103 of the SEC’s Regulation S-K requires disclosure of certain environmental matters when a governmental authority is a party to the proceedings, or such proceedings are known to be contemplated, unless we reasonably believe that the matter will result in no monetary sanctions, or in monetary sanctions, exclusive of interest and costs, below a stated threshold. In accordance with this SEC regulation, the Company uses a threshold of $1 million for purposes of determining whether disclosure of any such environmental proceedings is required. As of the date of this filing, we are not aware of any matters that are required to be disclosed pursuant to this standard.

From time to time, we are also named as defendants in personal injury and property damage lawsuits, including purported class actions, on the basis of having owned, operated or transported waste to a disposal facility that is alleged to have contaminated the environment or, in certain cases, on the basis of having conducted environmental remediation activities at sites. Some of the lawsuits may seek to have us pay the costs of monitoring of allegedly affected sites and health care examinations of allegedly affected persons for a substantial period of time even where no actual damage is proven. While we believe we have meritorious defenses to these lawsuits, the ultimate resolution is often substantially uncertain due to the difficulty of determining the cause, extent and impact of alleged contamination (which may have occurred over a long period of time), the potential for successive groups of complainants to emerge, the diversity of the individual plaintiffs’ circumstances, and the potential contribution or indemnification obligations of co-defendants or other third parties, among other factors. Additionally, we often enter into agreements with landowners imposing obligations on us to meet certain regulatory or contractual conditions upon site closure or upon termination of the agreements. Compliance with these agreements inherently involves subjective determinations and may result in disputes, including litigation.

Litigation — We are subject to various proceedings, lawsuits, disputes and claims arising in the ordinary course of our business. Many of these actions raise complex factual and legal issues and are subject to uncertainties. Actions that have been filed against us, and that may be filed against us in the future, include personal injury, property damage, commercial, customer, and employment-related claims, including purported state and national class action lawsuits related to: alleged environmental contamination, including releases of hazardous material and odors; sales and marketing practices, customer service agreements and prices and fees; and federal and state wage and hour and other laws. The plaintiffs in some actions seek unspecified damages or injunctive relief, or both. These actions are in various procedural stages, and some are covered, in part, by insurance. We currently do not believe that the eventual outcome of any such actions will have a material adverse effect on the Company’s business, financial condition, results of operations or cash flows.

In June 2022, we and certain of our officers were named as defendants in a complaint alleging violation of the federal securities laws and seeking certification as a class action in the U.S. District Court for the Southern District of New York. A lead plaintiff has been appointed and an amended complaint was filed in January 2023. The amended complaint seeks damages on behalf of a putative class of secondary market purchasers of our senior notes with a special mandatory redemption feature issued in May 2019, asserting claims under the Securities Exchange Act based on alleged misrepresentations and omissions concerning the time for completion of our acquisition of Advanced Disposal. Our motion to dismiss is pending. We will vigorously defend against this pending suit. We believe any potential recovery by the plaintiffs, in excess of applicable deductibles, will be covered by insurance, and we do not believe that the eventual outcome of this suit will have a material adverse effect on the Company’s business, financial condition, results of operations or cash flows.

WMI’s charter and bylaws provide that WMI shall indemnify against all liabilities and expenses, and upon request shall advance expenses to any person, who is subject to a pending or threatened proceeding because such person is or was a director or officer of the Company. Such indemnification is required to the maximum extent permitted under Delaware law. Accordingly, the director or officer must execute an undertaking to reimburse the Company for any fees advanced if it is later determined that the director or officer was not permitted to have such fees advanced under Delaware law. Additionally, the Company has direct contractual obligations to provide indemnification to each of the members of WMI’s Board of Directors and each of WMI’s executive officers. The Company may incur substantial expenses in connection with the fulfillment of its advancement of costs and indemnification obligations in connection with actions or proceedings that may be brought against its former or current officers, directors and employees.

Multiemployer Defined Benefit Pension Plans — About 20% of our workforce is covered by collective bargaining agreements with various local unions across the U.S. and Canada. As a result of some of these agreements, certain of our subsidiaries are participating employers in a number of trustee-managed multiemployer defined benefit pension plans (“Multiemployer Pension Plans”) for the covered employees. In connection with our ongoing renegotiation of various collective bargaining agreements, we may discuss and negotiate for the complete or partial withdrawal from one or more of these Multiemployer Pension Plans. A complete or partial withdrawal from a Multiemployer Pension Plan may also occur if employees covered by a collective bargaining agreement vote to decertify a union from continuing to represent them. Any other circumstance resulting in a decline in Company contributions to a Multiemployer Pension Plan through a reduction in the labor force, whether through attrition over time or through a business event (such as the discontinuation or nonrenewal of a customer contract, the decertification of a union, or relocation, reduction or discontinuance of certain operations) may also trigger a complete or partial withdrawal from one or more of these pension plans.

We do not believe that any future liability relating to our past or current participation in, or withdrawals from, the Multiemployer Pension Plans to which we contribute will have a material adverse effect on our business, financial condition or liquidity. However, liability for future withdrawals could have a material adverse effect on our results of operations or cash flows for a particular reporting period, depending on the number of employees withdrawn and the financial condition of the Multiemployer Pension Plan(s) at the time of such withdrawal(s).

Tax Matters — We participate in the IRS’s Compliance Assurance Process, which means we work with the IRS throughout the year towards resolving any material issues prior to the filing of our annual tax return. Any unresolved issues as of the tax return filing date are subject to routine examination procedures. In the fourth quarter of 2022, the Company received a notice of tax due for the 2017 tax year related to a remaining disagreement with the IRS. In response to the notice, the Company made a deposit of approximately $103 million with the IRS. The Company expects to seek a refund of the entire amount deposited with the IRS and litigate any denial of the claim for refund. As of September 30, 2023 and December 31, 2022, the IRS deposit, net of reserve for uncertain tax positions, is classified as a component of other long-term assets in the Company’s Condensed Consolidated Balance Sheets.

In addition, we are in the examination phase of IRS audits for the 2022 and 2023 tax years and expect the audits to be completed within the next 18 months. We are also currently undergoing audits by various state and local jurisdictions for tax years that date back to 2014. We maintain a liability for uncertain tax positions, the balance of which management believes is adequate. Results of audit assessments by taxing authorities are not currently expected to have a material adverse effect on our financial condition, results of operations or cash flows.

(a)

Mr. Carrasco’s stock trading plan provides that it shall remain in effect for as long as he is employed, unless affirmatively terminated sooner. The remaining stock trading plans will automatically terminate at the earlier of the applicable Plan Expiration Date set forth above or the completion of all of the contemplated transactions set forth therein.

(b)

Mr. Carrasco’s stock trading plan provides that, upon future vesting and payout of equity compensation awards granted to Mr. Carrasco by the Company or any affiliate, the Corporate Secretary shall cause to be sold the number of shares of common stock that, when added to tax withholding by the Company, will generate sufficient proceeds to cover the full anticipated personal federal tax obligations on account of such equity compensation award. The proceeds shall be remitted directly to the U.S. Internal Revenue Service. The number of shares of common stock to potentially be sold pursuant to this stock trading plan will depend on the terms of current unvested and future equity compensation awards granted to Mr. Carrasco and the Company’s achievement relative to applicable performance measures for such current unvested and future equity compensation awards.

(c)

Mr. Watson’s stock trading plan provides for the potential cashless exercise of 8,184 stock options, upon our common stock reaching a specified market price, pursuant to which shares of common stock will be sold to cover option costs, tax obligations, commissions and fees, and all net shares received after settlement will also be sold.

(d)

Mr. Watson’s stock trading plan also provides for the potential cashless exercise of 8,183 stock options, upon our common stock reaching a specified market price, pursuant to which shares of common stock will be sold to cover option costs, tax obligations, commissions and fees; Mr. Watson will then continue to hold all remaining shares of common stock resulting from the option exercise after the settlement.

(e)	Ms. Hemmer’s stock trading plan provides for a donation of 900 shares of our common stock upon our common stock reaching a specified market price.

(f)

Ms. Hemmer’s stock trading plan also provides for the sale of 25% of net after-tax shares of our common stock received upon the payout of performance share unit (“PSU”) equity compensation awards in 2024, for the performance period ending December 31, 2023, upon our common stock reaching each of three specified market prices, for an aggregate total sale of up to 75% of such net after-tax shares. Ms. Hemmer received a target grant of 11,930 PSU awards with a performance period ending December 31, 2023; the number of shares to be delivered to Ms. Hemmer on account of these PSU awards can range from zero to 200% of the initial target grant. As a result, the number of

shares of common stock to potentially be sold pursuant to this instruction will be determined based on the Company’s achievement relative to applicable performance measures for the underlying PSU awards.

(g)

Ms. Hemmer’s stock trading plan also provides for the potential cashless exercise of an aggregate of 27,005 stock options upon our common stock reaching specified market prices, pursuant to which shares of common stock will be sold to cover option costs, tax obligations, commissions and fees; Ms. Hemmer will then continue to hold all remaining shares of common stock resulting from the option exercise after settlement.

(h)

Mr. Morris’s stock trading plan provides for the sale of all net after-tax shares of our common stock received upon payout of PSU equity compensation awards in 2024, for the performance period ending December 31, 2023, upon our common stock reaching a specified market price. Mr. Morris received a target grant of 16,140 PSU awards with a performance period ending December 31, 2023; the number of shares to be delivered to Mr. Morris on account of these PSU awards can range from zero to 200% of the initial target grant. As a result, the number of shares of common stock to potentially be sold pursuant to this instruction will be determined based on the Company’s achievement relative to applicable performance measures for the underlying PSU awards.

(i)

Mr. Morris’s stock trading plan also provides for the potential cashless exercise of 17,778 stock options upon our common stock reaching a specified market price, pursuant to which shares of common stock will be sold to cover option costs, tax obligations, commissions and fees, and all net shares received after settlement will also be sold.

4. Income Taxes

Our effective income tax rate was 24.1% and 24.0% for the three and nine months ended September 30, 2023, respectively, compared with 22.8% and 23.5% for the three and nine months ended September 30, 2022, respectively.

The increase in our effective income tax rate when comparing the three and nine months ended September 30, 2023 and 2022 was primarily driven by (i) an unfavorable increase in permanent differences between taxable income and accounting income associated with our treatment of landfill closure and post-closure costs and (ii) a decrease in the excess tax benefits associated with equity-based compensation. The impacts of these items were partially offset by increased federal tax credits.

We evaluate our effective income tax rate at each interim period and adjust it as facts and circumstances warrant.

Permanent Differences — During the three and nine months ended September 30, 2023, we recognized additional income tax expense when compared to prior periods of $10 million and $16 million, respectively, related to permanent differences between taxable income and accounting income. This increase is largely due to an increase in taxable interest income associated with the Company’s election to deduct landfill closure and post-closure costs for income tax purposes when incurred and accrued. The increase in taxable interest income is due to the increase in the applicable federal rate published by the IRS.

Equity-Based Compensation – During the three and nine months ended September 30, 2023, we recognized a reduction in our income tax expense of $1 million and $11 million, respectively, for excess tax benefits related to the vesting or exercise of equity-based compensation awards compared with $5 million and $17 million, respectively, for the comparable prior year periods.

Investments Qualifying for Federal Tax Credits — We have significant financial interests in entities established to invest in and manage low-income housing properties. We support the operations of these entities in exchange for a pro-rata share of the tax credits they generate. The low-income housing investments qualify for federal tax credits that we expect to realize through 2033 under Section 42 or Section 45D of the Internal Revenue Code. We account for our investments in these entities using the equity method of accounting, recognizing our share of each entity’s results of operations and other reductions in the value of our investments in equity in net losses of unconsolidated entities, within our Condensed Consolidated Statements of Operations.

During the three and nine months ended September 30, 2023, we recognized $18 million and $43 million of net losses, respectively, and a reduction in our income tax expense of $28 million and $76 million, respectively, primarily due to federal tax credits realized from these investments as well as the tax benefits from the pre-tax losses realized. In addition, during the three and nine months ended September 30, 2023, we recognized interest expense of $3 million and $10 million, respectively, associated with our investments in low-income housing properties.

During the three and nine months ended September 30, 2022, we recognized $16 million and $47 million of net losses, respectively, and a reduction in our income tax expense of $26 million and $74 million, respectively, primarily due to federal tax credits realized from these investments as well as the tax benefits from the pre-tax losses realized. In addition, during the three and nine months ended September 30, 2022, we recognized interest expense of $5 million and $10 million,

respectively, associated with our investments in low-income housing properties. See Note 13 for additional information related to these unconsolidated variable interest entities.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Basis of Presentation
Basis of Presentation	The financial statements presented in this report represent the consolidation of Waste Management, Inc., a Delaware corporation; its wholly-owned and majority-owned subsidiaries; and certain variable interest entities for which Waste Management, Inc. or its subsidiaries are the primary beneficiaries as described in Note 13. Waste Management, Inc. is a holding company and all operations are conducted by its subsidiaries. When the terms “the Company,” “we,” “us” or “our” are used in this document, those terms refer to Waste Management, Inc., together with its consolidated subsidiaries and consolidated variable interest entities. When we use the term “WMI,” we are referring only to Waste Management, Inc., the parent holding company. We are North America’s leading provider of comprehensive environmental solutions, providing services throughout the United States (“U.S.”) and Canada. We partner with our customers and the communities we serve to manage and reduce waste at each stage from collection to disposal, while recovering valuable resources and creating clean, renewable energy. Our “Solid Waste” business is operated and managed locally by our subsidiaries that focus on distinct geographic areas and provide collection, transfer, disposal, and recycling and resource recovery services. Through our subsidiaries, including our Waste Management Renewable Energy (“WM Renewable Energy”) business, we are also a leading developer, operator and owner of landfill gas-to-energy facilities in the U.S. and Canada that produce renewable electricity and renewable natural gas, which is a significant source of fuel that we allocate to our natural gas fleet. Our senior management evaluates, oversees and manages the financial performance of our Solid Waste operations through two operating segments. Our East Tier primarily consists of geographic areas located in the Eastern U.S., the Great Lakes region and substantially all of Canada. Our West Tier primarily includes geographic areas located in the Western U.S., including the upper Midwest region, and British Columbia, Canada. Each of our Solid Waste operating segments provides integrated environmental services, including collection, transfer, recycling, and disposal. The East and West Tiers are presented in this report and constitute our existing Solid Waste business. We also provide additional services that are not managed through our Solid Waste business, which are presented in this report as “Other.” Additional information related to our segments is included in Note 7. The Condensed Consolidated Financial Statements as of September 30, 2023 and for the three and nine months ended September 30, 2023 and 2022 are unaudited. In the opinion of management, these financial statements include all adjustments, which, unless otherwise disclosed, are of a normal recurring nature, necessary for a fair presentation of the financial position, results of operations, comprehensive income, cash flows, and changes in equity for the periods presented. The results for interim periods are not necessarily indicative of results for the entire year. The financial statements presented herein should be read in conjunction with the financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2022. In preparing our financial statements, we make numerous estimates and assumptions that affect the accounting for and recognition and disclosure of assets, liabilities, equity, revenues and expenses. We must make these estimates and assumptions because certain information that we use is dependent on future events, cannot be calculated with precision from available data or simply cannot be calculated. In some cases, these estimates are difficult to determine, and we must exercise significant judgment. In preparing our financial statements, the most difficult, subjective and complex estimates and the assumptions that present the greatest amount of uncertainty relate to our accounting for landfills, environmental remediation liabilities, long-lived asset impairments, intangible asset impairments and the fair value of assets and liabilities acquired in business combinations. Actual results could differ materially from the estimates and assumptions that we use in the preparation of our financial statements.
Revenue Recognition	Revenue Recognition We generally recognize revenue as services are performed or products are delivered. For example, revenue typically is recognized as waste is collected, tons are received at our landfills or transfer stations, or recycling commodities are collected or delivered as product. We bill for certain services prior to performance. Such services include, among others, certain commercial and residential contracts, and equipment rentals. These advanced billings are included in deferred revenues and recognized as revenue in the period service is provided. Substantially all our deferred revenues during the reported periods are realized as revenues within one to three months, when the related services are performed. Contract Acquisition Costs Our incremental direct costs of obtaining a contract, which consist primarily of sales incentives, are generally deferred and amortized to selling, general and administrative expense over the estimated life of the relevant customer relationship, ranging from five to 13 years. Contract acquisition costs that are paid to the customer are deferred and amortized as a reduction in revenue over the contract life. Our contract acquisition costs are classified as current or noncurrent based on the timing of when we expect to recognize amortization and are included in other assets in our Condensed Consolidated Balance Sheets. As of September 30, 2023 and December 31, 2022, we had $207 million and $192 million, respectively, of deferred contract costs, of which $145 million and $137 million, respectively, was related to deferred sales incentives.
Leases	Leases Amounts for our operating lease right-of-use assets are recorded in long-term other assets and the current and long-term portion of our operating lease liabilities are reflected in accrued liabilities and other long-term liabilities, respectively, in our Condensed Consolidated Balance Sheets. Amounts for our financing leases are recorded in property and equipment, net of accumulated depreciation and depletion, and current or long-term debt in our Condensed Consolidated Balance Sheets, as appropriate.
Concentrations of Credit Risk	Concentrations of Credit Risk Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash and cash equivalents, investments held within restricted funds, and accounts receivable. We make efforts to control our exposure to credit risk associated with these instruments by (i) placing our assets and other financial interests with a diverse group of credit-worthy financial institutions; (ii) holding high-quality financial instruments while limiting investments in any one instrument and (iii) maintaining strict policies over credit extension that include credit evaluations, credit limits and monitoring procedures, although generally we do not have collateral requirements for credit extensions. We also control our exposure associated with trade receivables by discontinuing service, to the extent allowable, to non-paying customers.

Basis of Presentation

Basis of Presentation

1. Basis of Presentation

The financial statements presented in this report represent the consolidation of Waste Management, Inc., a Delaware corporation; its wholly-owned and majority-owned subsidiaries; and certain variable interest entities for which Waste Management, Inc. or its subsidiaries are the primary beneficiaries as described in Note 13. Waste Management, Inc. is a holding company and all operations are conducted by its subsidiaries. When the terms “the Company,” “we,” “us” or “our” are used in this document, those terms refer to Waste Management, Inc., together with its consolidated subsidiaries and consolidated variable interest entities. When we use the term “WMI,” we are referring only to Waste Management, Inc., the parent holding company.

We are North America’s leading provider of comprehensive environmental solutions, providing services throughout the United States (“U.S.”) and Canada. We partner with our customers and the communities we serve to manage and reduce waste at each stage from collection to disposal, while recovering valuable resources and creating clean, renewable energy. Our “Solid Waste” business is operated and managed locally by our subsidiaries that focus on distinct geographic areas and provide collection, transfer, disposal, and recycling and resource recovery services. Through our subsidiaries, including our Waste Management Renewable Energy (“WM Renewable Energy”) business, we are also a leading developer, operator and owner of landfill gas-to-energy facilities in the U.S. and Canada that produce renewable electricity and renewable natural gas, which is a significant source of fuel that we allocate to our natural gas fleet.

The Condensed Consolidated Financial Statements as of September 30, 2023 and for the three and nine months ended September 30, 2023 and 2022 are unaudited. In the opinion of management, these financial statements include all adjustments, which, unless otherwise disclosed, are of a normal recurring nature, necessary for a fair presentation of the financial position, results of operations, comprehensive income, cash flows, and changes in equity for the periods presented. The results for interim periods are not necessarily indicative of results for the entire year. The financial statements presented herein should be read in conjunction with the financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2022.

In preparing our financial statements, we make numerous estimates and assumptions that affect the accounting for and recognition and disclosure of assets, liabilities, equity, revenues and expenses. We must make these estimates and assumptions because certain information that we use is dependent on future events, cannot be calculated with precision from available data or simply cannot be calculated. In some cases, these estimates are difficult to determine, and we must exercise significant judgment. In preparing our financial statements, the most difficult, subjective and complex estimates and the assumptions that present the greatest amount of uncertainty relate to our accounting for landfills, environmental remediation liabilities, long-lived asset impairments, intangible asset impairments and the fair value of assets and liabilities acquired in business combinations. Actual results could differ materially from the estimates and assumptions that we use in the preparation of our financial statements.

Revenue Recognition

We generally recognize revenue as services are performed or products are delivered. For example, revenue typically is recognized as waste is collected, tons are received at our landfills or transfer stations, or recycling commodities are collected or delivered as product. We bill for certain services prior to performance. Such services include, among others, certain commercial and residential contracts, and equipment rentals. These advanced billings are included in deferred revenues and recognized as revenue in the period service is provided. Substantially all our deferred revenues during the reported periods are realized as revenues within one to three months, when the related services are performed.

Contract Acquisition Costs

Our incremental direct costs of obtaining a contract, which consist primarily of sales incentives, are generally deferred and amortized to selling, general and administrative expense over the estimated life of the relevant customer relationship, ranging from five to 13 years. Contract acquisition costs that are paid to the customer are deferred and amortized as a reduction in revenue over the contract life. Our contract acquisition costs are classified as current or noncurrent based on the timing of when we expect to recognize amortization and are included in other assets in our Condensed Consolidated Balance Sheets. As of September 30, 2023 and December 31, 2022, we had $207 million and $192 million, respectively, of deferred contract costs, of which $145 million and $137 million, respectively, was related to deferred sales incentives.

Leases

Amounts for our operating lease right-of-use assets are recorded in long-term other assets and the current and long-term portion of our operating lease liabilities are reflected in accrued liabilities and other long-term liabilities, respectively, in our Condensed Consolidated Balance Sheets. Amounts for our financing leases are recorded in property and equipment, net of accumulated depreciation and depletion, and current or long-term debt in our Condensed Consolidated Balance Sheets, as appropriate.

Concentrations of Credit Risk

Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash and cash equivalents, investments held within restricted funds, and accounts receivable. We make efforts to control our exposure to credit risk associated with these instruments by (i) placing our assets and other financial interests with a diverse group of credit-worthy financial institutions; (ii) holding high-quality financial instruments while limiting investments in any one instrument and (iii) maintaining strict policies over credit extension that include credit evaluations, credit limits and monitoring procedures, although generally we do not have collateral requirements for credit extensions. We also control our exposure associated with trade receivables by discontinuing service, to the extent allowable, to non-paying customers. However, our overall credit risk associated with trade receivables is limited due to the large number and diversity of customers we serve.

Fair Value of Debt

As of September 30, 2023 and December 31, 2022, the carrying value of our debt was $15.4 billion and $15.0 billion, respectively. The estimated fair value of our debt was approximately $13.8 billion as of September 30, 2023 and December 31, 2022.

Although we have determined the estimated fair value amounts using available market information and commonly accepted valuation methodologies, considerable judgment is required in interpreting market data to develop the estimates of fair value. Accordingly, our estimates are not necessarily indicative of the amounts that we, or holders of the instruments, could realize in a current market exchange. The use of different assumptions or estimation methodologies could have a material effect on the estimated fair values. The fair value estimates are based on Level 2 inputs of the fair value hierarchy available as of September 30, 2023 and December 31, 2022. These amounts have not been revalued since those dates, and current estimates of fair value could differ significantly from the amounts presented.

8. Acquisitions

During the nine months ended September 30, 2023, we completed solid waste and recycling acquisitions with total consideration of $138 million, which included $129 million in cash paid and $9 million of other consideration, specifically purchase price holdbacks. In addition, we paid $10 million of holdbacks, of which $6 million related to prior year acquisitions.

Total consideration for our 2023 acquisitions was allocated to $22 million of property and equipment, $46 million of other intangible assets, primarily customer relationships, and $76 million of goodwill with the remaining allocated to liabilities assumed from the ordinary course of business. We remain in the measurement period for most of our acquisitions, and adjustments to our preliminary purchase price allocation may occur. The goodwill was primarily a result of expected synergies from combining the acquired businesses with our existing operations and substantially all was tax deductible.
