Report of Independent Registered Public Accounting Firm

To the Administrative Committee of the

Waste Management Retirement Savings Plan

Opinion on the Financial Statements

We have audited the accompanying statements of net assets available for benefits of the Waste Management Retirement Savings Plan (the Plan) as of December 31, 2023 and 2022, and the related statement of changes in net assets available for benefits for the year ended December 31, 2023, and the related notes and schedules (collectively referred to as the financial statements). In our opinion, the financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2023 and 2022, and the changes in net assets available for benefits for the year ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of Plan management. Our responsibility is to express an opinion on these financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Plan in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

The supplementary information is the responsibility of Plan management. Our audit procedures included determining whether the supplemental information reconciles to the financial statements or the underlying accounting and other records, as applicable and performing procedures to test the completeness and accuracy of the information presented in the supplemental information.

Waste Management Retirement Savings Plan

Notes to Financial Statements

December 31, 2023

1. Description of Plan

The following description of the Waste Management Retirement Savings Plan (the “Plan”) provides only general information. Participants should refer to the Summary Plan Description and the plan document for a more complete description of the Plan’s provisions.

General

The Plan is a defined contribution plan sponsored by Waste Management, Inc. (the “Company” or “WMI”), and eligible affiliates (as defined in the Plan) (collectively “Waste Management”) for the benefit of eligible employees and their beneficiaries. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”).

Administration

The Administrative Committee of the Waste Management Employee Benefit Plans (the “Administrative Committee”) has been named to serve as administrator and fiduciary of the Plan. Bank of America, N.A. (“Bank of America”) serves as trustee of the Plan pursuant to a Defined Contribution Plan Trust Agreement and also serves as the Plan’s third-party recordkeeper.

Eligibility

Employees (as defined by the Plan) are eligible to participate in the Plan following completion of a 90-day period of service (as defined by the Plan).

Individuals who are ineligible to participate in the Plan consist of (a) leased employees; (b) employees whose employment is governed by a collective bargaining agreement that does not provide for participation in the Plan for such individual; (c) individuals providing services to the Company and who are designated as independent contractors; (d) employees performing services on a seasonal or temporary basis; (e) any individual who is not regularly employed in, or a citizen of, the United States and (f) individuals who are participants in certain other pension, retirement, profit-sharing, stock bonus, thrift or savings plans maintained by Waste Management. Certain United States citizens employed by foreign affiliates of the Company may participate in the Plan under certain provisions specified by the Plan.

Contributions

Participants are permitted to contribute as much as 50% of their eligible annual compensation, as defined by the Plan, and 80% of their annual incentive plan bonus, subject to annual contribution limitations established by the Internal Revenue Service (“Employee Contribution”). In addition, participants that are age 50 or older are eligible to make pre-tax catch-up contributions not to exceed certain limits described in the Plan document. After-tax contributions are permitted by the Plan. Participants may also contribute amounts representing distributions from other qualified plans (“Rollover Contributions”).

With respect to each participant whose employment is not governed by a collective bargaining agreement, Waste Management matches 100% of each participant’s Employee Contribution up to 3% of the participant’s eligible annual compensation, as defined by the Plan, plus 50% of the participant’s Employee Contribution on the next 3% of the participant’s eligible annual compensation. Any such employee is automatically enrolled in the Plan at a contribution rate of 3% of eligible compensation, unless changed by the employee.

Table of Contents

With respect to each participant whose employment relationship is covered by a collective bargaining agreement, the amount of contributions by Waste Management, if any, is provided for in the applicable collective bargaining agreement.

Nonvested Forfeitures, Unclaimed Distributions and Other

As of December 31, 2023 and 2022, nonvested forfeitures, unclaimed distributions and other unallocated accounts, including settlements, totaled $1,070,817 and $1,283,558, respectively. These accounts will be used to reduce future Waste Management contributions and/or to pay Plan expenses. During 2023, $547,601 from these accounts was used to fund Waste Management’s required contributions and pay Plan expenses.

Investment Options

The Plan offers participants diversified investment options. As of December 31, 2023, the Plan offered (a) 14 common collective trust funds (including eight target retirement-date funds and a stable value fund); (b) three mutual funds; (c) a WMI common stock fund (which is an Employee Stock Ownership Plan) and (d) a self-directed brokerage account, which allows participants to select various securities sold on the New York Stock Exchange, NYSE American (formerly the American Stock Exchange) and NASDAQ. Participants direct investment of their accounts among the investment options offered under the Plan. A participant may make such an election on any business day. The Plan utilizes cash equivalents to temporarily hold monies pending settlement for transactions initiated by participants.

If a participant invests in the WMI common stock fund, the participant can elect to receive in cash any dividends paid on the common stock in the participant’s account. If a participant does not make such an election, dividends will automatically be reinvested in the WMI common stock fund. Each participant who has invested in the WMI common stock fund has the right to vote the shares of stock in his or her account with respect to any matter that comes before the shareholders for a vote.

With respect to the self-directed brokerage account, several restrictions apply and a minimum balance is required to participate. Additionally, if a participant invests in the self-directed brokerage account, the participant has the right to vote the shares of securities held in the participant’s account.

Vesting

Participants are immediately vested in their Employee Contributions, Rollover Contributions and Employer Contributions, plus earnings thereon.

Participant Accounts

Each participant’s account is credited with the participant’s Employee Contribution, Rollover Contribution and any Employer Contribution and an allocation of investment income and loss and expenses. Investment income and loss is allocated to a participant’s account based upon a participant’s proportionate share of the funds within the Plan.

Payment of Benefits

Upon retirement, disability or termination of employment, participants or, in the case of a participant’s death, their designated beneficiaries, may make withdrawals from their accounts as specified by the Plan. Prior to termination, participants who have reached age 59-1/2 may withdraw from their accounts. Distributions are made by a single lump-sum payment or direct rollover. Distributions of accounts invested in WMI common stock may be taken in whole shares of common stock or cash.

Participants may make withdrawals from their contributions, including certain earnings on those contributions, in the event of proven financial hardship of the participant.

Table of Contents

Notes Receivable from Participants

Notes receivable from participants represent participant loans that are recorded at their unpaid principal balance plus any accrued but unpaid interest. Interest income on notes receivable from participants is recorded when it is earned. No allowance for credit losses has been recorded as of December 31, 2023 and 2022. If a participant ceases to make loan repayments and the Plan administrator deems the participant loan to be a distribution, the participant loan balance is reduced and a benefit payment is recorded. Participants who are active employees may obtain loans of not less than $1,000 and a maximum of 50% of a participant’s vested accounts (excluding any amounts invested in the self-directed brokerage account) immediately preceding the loan grant date. In no event shall a loan exceed $50,000, reduced by the greater of (a) the highest outstanding balance of loans during the one-year period ending on the date before a new loan is made or modified or (b) the outstanding balance of loans on the date a new loan is made or modified. Not more than one loan shall be outstanding at any time, except for multiple loans which (a) result from a merger of another plan into this Plan or (b) result from a participant’s defaulting on a loan. Interest rates and repayment terms are established by the Administrative Committee. Such loans shall be repaid by payroll deduction or any other method approved by the Administrative Committee. The Administrative Committee requires that: (a) no more than one loan per year be taken by a participant; (b) repayments be made no less frequently than quarterly; (c) loans be repaid over a period not to exceed 54 months and (d) repayments, including interest, be made in equal periodic payments over the term of the loan and applied to principal using a level amortization over the repayment period. Prepayment of a participant’s total principal amount outstanding is allowed at any time.

Administrative Expenses

Administrative expenses of the Plan are generally allocated among participants. Loan administration fees and certain other expenses are charged directly to the account balance of the applicable participant. In 2023, Waste Management elected to pay certain audit and legal fees of the Plan.

2. Summary of Accounting Policies

Basis of Accounting

The accompanying financial statements of the Plan have been prepared using the accrual basis of accounting in accordance with accounting principles generally accepted in the United States (“GAAP”). Benefits are recorded when paid to participants.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires the Plan’s management to make estimates and assumptions that affect the reported amounts of net assets available for benefits as of the date of the financial statements and the changes in net assets available for benefits during the reporting period and, when applicable, disclosures of contingent assets and liabilities as of the date of the financial statements. Actual results could differ materially from the estimates and assumptions used in the preparation of the financial statements.

Investments

Corporate stocks, mutual funds and publicly-traded partnership interests held by the Plan are stated at fair value based on quoted market prices as of the financial statement date. The fair values of the common collective trust funds held by the Plan are generally based on net asset values established by the issuer of the common collective trust funds based on fair values of the underlying assets. Short-term investments (included in amounts reported as common collective trust funds herein) are stated at cost, which approximates fair value.

The Plan records purchases and sales of securities on a trade-date basis and dividends on the ex-dividend date. Interest income is recorded on the accrual basis.

Table of Contents

Contributions

Contributions from Plan participants and the matching contributions from the Company are recorded in the year in which the employee contributions are withheld from compensation.

Risks and Uncertainties

The Plan makes investments in securities. Investment securities are exposed to various risks, such as interest rate, macroeconomic, market and credit risks that impact the value of such securities. Risks include, but are not limited to, general economic conditions, political developments, international conflict and instability of markets and financial institutions. The impacts of any such risks cannot be predicted at this time, but it is possible that changes in values of investment securities could materially affect participant account balances and the amounts reported in the Statements of Net Assets Available for Benefits.

Reclassifications

When necessary, reclassifications are made to the prior year financial information to conform to the current year presentation.

3. Investment in Stable Value Fund

The Plan’s investment option for the stable value fund is managed by the John Hancock Stable Value Return Trust, a Collective Investment Trust offered by the John Hancock Trust Company and is included in investments at fair value in the Statement of Net Assets Available for Benefits as of December 31, 2023. The fund also invests in an uninsured separately managed account portfolio of short-term investments, the John Hancock Short Term Investment Fund (STIF) to provide daily liquidity for plan and participant level transactions.

Risks arise when entering into any investment contract due to the potential inability of the issuer to meet the terms of the contract. In addition, security‐backed investment contracts, also called stabilizing agreements or synthetic guaranteed investment contracts, have the risk of default or the lack of liquidity of the underlying portfolio assets. The credit risk of each issuer was evaluated and monitored through the portfolio manager’s credit analysis. The credit analysis included, but was not limited to, asset quality and liquidity, management quality, surplus adequacy, and profitability. John Hancock on behalf of the Plan, requires that the issuers of each contract have a minimum quality rating as of the contract effective date and that all underlying portfolio assets be rated investment grade at the time of purchase.

4. Fair Value Measurements

For purposes of the Plan’s financial reporting, fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When measuring assets and liabilities that are required to be recorded at fair value, the Plan considers the principal or most advantageous market in which the Plan would transact. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:

Level 1 — Quoted prices in active markets for identical assets or liabilities.

Level 2 — Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 — Inputs that are generally unobservable and typically reflect the Plan’s estimate of assumptions that market participants would use in pricing the asset or liability. The Plan had no Level 3 assets as of December 31, 2023 or 2022.

Table of Contents

We use valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. In measuring the fair value of our assets and liabilities, we use market data or assumptions that we believe market participants would use in pricing an asset or liability, including assumptions about risk when appropriate.

The following table provides by level, within the fair value hierarchy, a summary of investments of the Plan as of December 31 measured at fair value on a recurring basis:


	2023		2022
Quoted Prices in Active Markets (Level 1):
Mutual funds	$	263,940,693	$	230,650,520
WMI common stock		319,974,315		293,785,482
Self-directed brokerage accounts		90,947,526		70,807,791
Subtotal Level 1		674,862,534		595,243,793

Significant Other Observable Inputs (Level 2):
Self-directed brokerage accounts — FedFund		9,083,850		9,537,063
FedFund		1,106,888		1,190,207
Subtotal Level 2		10,190,738		10,727,270

Investments Measured at Net Asset Value (a):
Common collective trust funds		2,914,352,719		2,516,159,962
Subtotal Investments Measured at Net Asset Value		2,914,352,719		2,516,159,962
Total Investments at Fair Value	$	3,599,405,991	$	3,122,131,025

(a)

Certain investments that are measured at fair value using the net asset value per share (or its equivalent) practical expedient have not been categorized in the fair value hierarchy. The fair value amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the Statements of Net Assets Available for Benefits. As of December 31, 2023 and 2022, there were no redemption restrictions on the investments held at net asset value other than possible advance notice requirements.

5. Federal Income Taxes

The Plan has received a determination letter from the Internal Revenue Service (“IRS”) dated April 30, 2015, stating that the Plan, as amended and restated as of January 1, 2015, was in compliance with the applicable requirements of the Internal Revenue Code (the "Code"), which were timely adopted by the Plan sponsor subsequent to receipt of the determination letter. The Plan sponsor has adopted a further amendment and restatement of the Plan and subsequent amendments since receiving the determination letter. The Plan administrator and counsel believe that the Plan is currently designed and being operated in compliance with the applicable requirements of the Code. If an operational issue is discovered, the Plan sponsor has indicated that it will take any necessary steps to bring the Plan’s operations into compliance with the Code.

GAAP requires Plan management to evaluate uncertain tax positions taken by the Plan. The financial statement effects of a tax position are recognized when the position is more likely than not, based on the technical merits, to be sustained upon examination by the IRS. The Plan administrator has analyzed the tax positions taken by the Plan, and has concluded that as of December 31, 2023, there are no uncertain tax positions taken or expected to be taken. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress. The Plan administrator believes it is no longer subject to income tax examinations for years prior to 2020.

Amounts pending distribution to participants as of December 31, 2023		(81,465)
Net increase in assets available for benefits per the Form 5500	$	487,834,273

7. Plan Termination

Although it has not expressed any intention to do so, the Company has the right to discontinue its Plan contribution at any time and to terminate the Plan subject to the provisions of ERISA.

8. Related-Party Transactions

Bank of America serves as the trustee and third-party recordkeeper of the Plan. Merrill Lynch, Pierce, Fenner & Smith Incorporated, a Bank of America Company, provides securities brokerage services for the self-directed brokerage account. State Street Bank and Trust Company serves as the independent fiduciary for the WMI common stock fund. The Plan also holds notes receivable representing participant loans. These transactions qualify as party-in-interest transactions. Additionally, a portion of the Plan’s assets are invested in WMI common stock. As WMI is the Plan sponsor, transactions involving WMI common stock also qualify as party-in-interest transactions. The Plan sponsor believes that all of these transactions are exempt from the prohibited transactions rules.
