#### PART I

#### Item 1. Business.

#### General
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.

WMI was incorporated in Oklahoma in 1987 under the name "USA Waste Services, Inc." and was reincorporated as a Delaware company in 1995. In a 1998 merger, the Illinois-based waste services company formerly known as Waste Management, Inc. became a wholly-owned subsidiary of WMI and changed its name to Waste Management Holdings, Inc. ("WM Holdings"). At the same time, our parent holding company changed its name from USA Waste Services to Waste Management, Inc. Like WMI, WM Holdings is a holding company and all operations are conducted by subsidiaries.

Our principal executive offices are located at 800 Capitol Street, Suite 3000, Houston, Texas 77002. Our telephone number is (713) 512-6200. Our website address is www.wm.com. Our annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K are all available, free of charge, on our website as soon as practicable after we file the reports with the SEC. Our stock is traded on the New York Stock Exchange under the symbol "WM."

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, recycling and resource recovery services. Through our Waste Management Renewable Energy ("Renewable Energy") segment, 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 ("RNG"), which is a significant source of fuel that we allocate to our natural gas fleet. Following our 2024 acquisition of Stericycle, Inc. ("Stericycle"), our Healthcare Solutions segment provides regulated waste and compliance services ("RWCS") and secure information destruction ("SID") services in the U.S., Canada and Western Europe that protect people and brands, promote health and well-being and safeguard the environment. Additionally, through our Recycling Processing and Sales segment, we are a leading recycler in the U.S. and Canada, handling materials that include paper, cardboard, glass, plastic and metal. During 2025, our largest customer represented less than 5% of annual revenues.

We own or operate 257 landfill sites, which is the largest network of landfills throughout the U.S. and Canada. In order to make disposal more practical for larger urban markets, where the distance to landfills is typically farther, we manage 342 transfer stations, excluding those acquired from Stericycle, that consolidate, compact and transport waste efficiently and economically. We also use waste to create energy, recovering the gas produced naturally as waste decomposes in landfills and using the gas in generators to make electricity. We are a leading recycler in the U.S. and Canada, handling materials that include cardboard, paper, glass, plastic and metal. We provide cost-efficient, environmentally sound recycling programs for municipalities, businesses and households across the U.S. and Canada as well as other services that supplement our solid waste business.

Our fundamental strategy has not changed; we remain dedicated to providing long-term value to our stockholders by successfully executing our core strategy of focused differentiation and continuous improvement. We have enabled a people-first, technology-led focus to drive our mission to maximize resource value, while minimizing environmental impact, and sustainability and environmental stewardship is embedded in all that we do. Our strategy leverages and sustains the strongest asset network in the industry to drive best-in-class customer experience and growth. Our strategic planning processes appropriately consider that the future of our business and the industry can be influenced by changes in economic conditions, the competitive landscape, the regulatory environment, asset and resource availability and technology. We believe that focused differentiation, which is driven by capitalizing on our unique and extensive network of assets, will deliver profitable growth and position us to leverage competitive advantages. Simultaneously, we believe that investing in

[**Table of Contents**](#TOC)

automation to improve processes and drive operational efficiency combined with a focus on the cost to serve our customers will yield an attractive profit margin and enhanced service quality. We are furthering our strategy of focused differentiation and continuous improvement beyond our traditional waste operations through our sustainability growth strategy that includes significant investments in our Renewable Energy and Recycling Processing and Sales segments, while increasing automation and reducing labor dependency. In addition, with our acquisition of Stericycle, we have advanced our growth strategy and built upon our sustainability initiatives. The acquisition provides a complementary business platform in medical waste, a sector with attractive near- and long-term growth dynamics, and in secure information destruction services to further our leading suite of comprehensive waste and environmental solutions. Furthermore, we continue to evaluate and plan to pursue emerging diversion technologies that may generate additional value.

Our Company's goals are targeted at putting our people first, positioning them to serve and care for our customers, the environment, the communities in which we work and our stockholders. Our brand promise is ALWAYS WORKING FOR A SUSTAINABLE TOMORROW<sup>®</sup>. We live this promise through our service offerings and sustainable solutions, our investments in innovation, our people and our commitment to the future. Through our longtime focus on finding sustainable solutions, we continue to evolve beyond being a traditional environmental waste services company. Increasingly, our industry-leading focus on environmental sustainability aligns with demand from our customers who want more of their waste materials recovered. Waste streams are becoming more complex, and our aim is to address current needs, while anticipating the expanding and evolving needs of our customers. We believe we are uniquely equipped to meet the challenges of the changing waste industry and our customers' waste management needs, both today and tomorrow as we work together to envision and create a more sustainable future.

We believe that execution of our strategy will deliver shareholder value and leadership in a dynamic industry and in any economic environment. In addition, we intend to continue to return value to our stockholders through dividend payments and share repurchases. In December 2025, we announced that our Board of Directors expects to increase the quarterly dividend from $0.825 to $0.945 per share for dividends declared in 2026, which is a 14.5% increase from the quarterly dividends we declared in 2025. This is an indication of our ability to generate strong and consistent cash flows and marks the 23rd consecutive year of dividend increases. All quarterly dividends will be declared at the discretion of our Board of Directors and depend on various factors, including our net earnings, financial condition, cash required for future business plans, growth and acquisitions and other factors the Board of Directors may deem relevant. Additionally, given the substantial progress already made on leverage reduction following the Stericycle acquisition, we resumed share repurchases in February 2026. Our Board of Directors approved up to $3.0 billion in future share repurchases, exclusive of fees, commissions and taxes. This new authorization supersedes and replaces the remaining authority under the prior Board of Directors' authorization for share repurchases announced in December 2023. Under this new authorization, we currently expect to repurchase approximately $2.0 billion of shares during 2026, while continuing to prioritize a return to our targeted leverage level during the year. The amount of future share repurchases executed under our Board of Directors' authorization is determined in management's discretion, based on various factors, including our leverage level, net earnings, financial condition and cash required for future business plans, growth and acquisitions.

#### Operations

#### General
Our senior management evaluates, oversees and manages the financial performance of our business through five reportable segments, referred to as (i) Collection and Disposal - East Tier ("East Tier"); (ii) Collection and Disposal - West Tier ("West Tier"); (iii) Recycling Processing and Sales; (iv) Renewable Energy and (v) Healthcare Solutions. Our East and West Tiers, along with certain ancillary services ("Other Ancillary") that are not managed through our Tier segments but that support our collection and disposal operations, form our "Collection and Disposal" businesses.

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, Southern and Central U.S., including the upper Midwest region, and British Columbia, Canada.

We also provide additional services not managed through our five reportable segments, which are presented as Corporate and Other. For further discussion refer to Note 19 of our Consolidated Financial Statements.

[**Table of Contents**](#TOC)

***Collection and Disposal***

Services provided through our Collection and Disposal businesses are described below:

*Collection.* Our commitment to customers begins with a vast waste collection network. Collection involves picking up and transporting waste and recyclable, construction and demolition, and organic materials from where it was generated to a transfer station, recycling facility or disposal site. We generally provide collection services under one of two types of arrangements:

● For commercial and industrial collection services, typically we have three-year service agreements. The fees under the agreements are influenced by factors such as collection frequency, type of collection equipment we furnish, type and volume or weight of the waste collected, distance to the disposal facility, labor costs, fuel costs, truck types, cost of disposal and general market factors. As part of the service, we provide steel containers to most customers to store their solid waste between pick-up dates. Containers vary in size and type according to the needs of our customers and the restrictions of their communities. Many are designed to be lifted mechanically and either emptied into a truck's compaction hopper or directly delivered to a disposal site. By using these containers, we can service most of our commercial and industrial customers with trucks operated by only one employee.

● For most residential collection services, we have a contract with, or a franchise granted by, a municipality, homeowners' association or some other regional authority that gives us the exclusive right to service all or a portion of the homes in an area. These contracts or franchises are typically for periods of three to ten years and typically mirror terms as allowed by statutes by state. We also provide services under individual monthly subscriptions directly to households. The fees for residential collection are either paid by the municipality or authority from their tax revenues or service charges, or are paid directly by the residents receiving the service. The Company is generally phasing out traditional manual systems and moving to further automate residential collection services. Benefits of automation include enhanced worker safety, containerization of waste, improved service delivery to the customer and an overall reduction in the cost to provide services.

*Landfill.* Landfills are the main depositories for solid waste in North America. As of December 31, 2025, we owned or operated 253 solid waste landfills and four hazardous waste landfills, which represents the largest network of landfills throughout the U.S. and Canada. As of December 31, 2025, we owned or controlled the management of 244 sites with remedial activities that are in closure or have received a certification of closure from the applicable regulatory agency. Solid waste landfills are constructed and operated on land with engineering safeguards that limit the possibility of water and air pollution and are operated under procedures prescribed by regulation. A landfill must meet federal, state and/or provincial and local regulations during its design, construction, operation and closure. The operation and closure activities of a solid waste landfill include excavation, construction of liners, continuous spreading and compacting of waste, covering of waste with earth or other acceptable material and constructing final capping of the landfill. These operations are carefully planned to maintain environmentally safe conditions and to maximize the use of the airspace.

All solid waste management companies must have access to a disposal facility, such as a solid waste landfill. The significant capital requirements of developing and operating a landfill serve as a barrier to landfill ownership and, thus, third-party haulers often dispose of waste at our landfills. It is usually preferable for our collection operations to use disposal facilities that we own or operate, a practice we refer to as internalization, rather than using third-party disposal facilities. Internalization generally allows us to realize higher consolidated margins and stronger operating cash flows. The fees charged at disposal facilities, which are referred to as tipping fees, are based on several factors, including our cost to construct, maintain and close the landfill, the distance to an alternative disposal facility, the type and weight or volume of solid waste deposited and competition.

Under environmental laws, the federal government (or states with delegated authority) must issue permits for all hazardous waste landfills. All of our hazardous waste landfills have obtained the required permits, although some can accept only certain types of hazardous waste. These landfills must also comply with specialized operating standards. Only hazardous waste in a stable, solid form, which meets regulatory requirements, can be deposited in our secure disposal cells. In some cases, hazardous waste can be treated before disposal. Generally, these treatments involve the separation or

[**Table of Contents**](#TOC)

removal of solid materials from liquids and chemical treatments that transform waste into inert materials that are no longer hazardous. Our hazardous waste landfills are sited, constructed and operated in a manner designed to provide long-term containment of waste. We also operate a hazardous waste facility at which we isolate treated hazardous waste in liquid form by injection into deep wells that have been drilled in certain acceptable geologic formations far below the base of fresh water to a point that is safely separated by other substantial geological confining layers.

Included within our Collection and Disposal businesses are landfills having (i) 19 third-party power generating facilities converting our landfill gas to fuel electricity generators; (ii) 17 third-party RNG facilities processing landfill gas to be sold to natural gas suppliers and (iii) nine third-party projects delivering our landfill gas by pipeline to industrial customers as a direct substitute for fossil fuels in industrial processes. In return for providing our landfill gas, we receive royalties from each facility, including the benefit of a 15% royalty from our Renewable Energy segment based on net operating revenue generated through the sale of RNG, renewable identification numbers ("RINs"), electricity and capacity, Renewable Energy Credits ("RECs") and related environmental attributes from the 86 landfill beneficial use renewable energy projects owned by Renewable Energy on our active landfills, which is eliminated in consolidation.

*Transfer.* As of December 31, 2025, we owned or operated 342 transfer stations in the U.S. and Canada. We deposit waste at these stations, as do other waste haulers. The solid waste is then consolidated and compacted to reduce the volume and increase the density of the waste and transported by transfer trucks, rail or barge to disposal sites.

Access to transfer stations is critical to haulers who collect waste in areas not in close proximity to disposal facilities. Fees charged to third parties at transfer stations are usually based on the type and volume or weight of the waste deposited at the transfer station, the distance to the disposal site, market rates for disposal costs and other general market factors.

The utilization of our transfer stations by our own collection operations improves internalization by allowing us to retain fees that we would otherwise pay to third parties for the disposal of the waste we collect. It enables us to manage costs associated with waste disposal because (i) transfer trucks, railcars, rail containers or barge containers have larger capacities than collection trucks, allowing us to deliver more waste to the disposal facility in each trip; (ii) waste is accumulated and compacted at transfer stations that are strategically located to increase the efficiency of our network of operations and (iii) we can retain the volume by managing the transfer of the waste to one of our own disposal sites.

The transfer stations that we operate but do not own generally are operated through lease agreements under which we lease property from third parties. There are some instances where transfer stations are operated under contract, generally for municipalities. In most cases, we own the permits and will be responsible for any regulatory requirements relating to the operation and closure of the transfer station.

*Other*. Other businesses providing collection and disposal services include the following:

*Strategic Business Solutions ("WMSBS")* — Although many waste management services such as collection and disposal are local services, our WMSBS business works with customers whose locations span the U.S. and Canada. Our strategic accounts program provides these customers with streamlined service, enhanced reporting, measurement tools aimed at meeting sustainability objectives and centralized billing and management of accounts.

*Sustainability and Environmental Solutions ("SES")* — Our SES business collaborates with our geographic areas and national accounts sales team to offer our customers end-to-end solutions that help businesses achieve their sustainability, recycling and waste diversion goals while meeting industry-specific compliance requirements and rising environmental demands. These solutions include (i) Sustainability Services, where our employees provide full-service waste management solutions and advisory services, working full-time onsite at our customers' facilities or through remote-managed programs (this service is managed through our SES business but reflected principally in our collection line of business); (ii) remediation and construction services; (iii) management and marketing of fly ash, which is residue generated from the combustion of coal to generate electricity and (iv) industrial waste services, which uses thermal and mechanical separation technologies to minimize waste volumes and recover commodities at the point of generation. The breadth of these service offerings, combined with our large and expanding network of technology-enabled infrastructure in recycling, organics and renewable energy give us the ability to help customers reduce the amount of waste they generate, identify recycling

[**Table of Contents**](#TOC)

opportunities and determine efficient and environmentally friendly means for waste collection and disposal. Through these services, we aim to help customers increase circularity and accelerate their decarbonization goals.

***Recycling Processing and Sales***

Recycling involves the separation of reusable materials from the waste stream for processing and resale or other disposition. We are North America's leading recycler of post-consumer materials. We not only collect materials from households and businesses across the U.S. and Canada, we also process and sell them to manufacturers to be recycled and sold generally within the North American market. Demand for recycled materials is generally growing. Several states have passed minimum-recycled-content mandates, and companies are responding to requirements for recycled content from their own customers and to meet sustainability targets. We are helping expand the availability of recycled materials by investing in infrastructure, increasing access to recycling services and educating customers through our Recycle Right<sup>®</sup> program.

Our recycling operations provide communities and businesses with an alternative to traditional landfill disposal and support our strategic goals to extract more value from the materials we manage. We were the first major solid waste company to focus on residential single-stream recycling, which allows customers to mix clean bottles, cans, paper, cups, tubs and cardboard in one bin. Residential single-stream programs have greatly increased recycling volumes. Single-stream recycling is possible through the use of various mechanized screens and optical sorting technologies. In addition to advancing our single stream recycling programs for commercial applications, we continue to invest in recycling technologies and businesses designed to offer services and solutions to support and grow our current operations. We are investing in enhanced recycling facility technology at new and existing facilities to benefit labor productivity, support increased recycling capacity and allow for dynamic adjustments to respond to evolving end-market demands. In 2025 and 2024, we opened eight and three new recycling facilities, respectively, within the U.S. and Canada equipped with advanced recycling technology. We continue to invest in recycling facility automation and new markets across the U.S. and Canada. Our Recycling Processing and Sales segment includes the following:

*Materials processing —* Through our collection operations and third-party customer base, we collect recyclable materials from residential, commercial and industrial customers and direct these materials to one of our recycling facilities for processing. As of December 31, 2025, we operated 113 recycling facilities, of which 51 are single stream, where cardboard, paper, glass, metals, plastics, construction and demolition materials and other recycling commodities are recovered for resale or redirected for other purposes.

*Recycling commodities —* We market and resell recycling commodities globally. We manage the marketing of recycling commodities that are processed in our facilities by continuously analyzing market prices, logistics, market demands and product quality through our dedicated recycling service centers and account managers.

*Recycling brokerage services* — We also provide recycling brokerage services, which involve managing the marketing of recyclable materials for third parties. Our experience in managing recycling commodities for our own operations gives us the expertise needed to effectively manage volumes for third parties. Utilizing the resources and capabilities of our recycling service centers and account managers, we can assist customers in marketing and selling their recycling commodities with minimal capital requirements.

*Organics processing and sales* — We collect recyclable food and yard waste from commercial, residential, and industrial customers, and process these materials through a network of mulching, composting, CORe®, and anaerobic digestion facilities. As of December 31, 2025, we operated 49 organics recycling facilities and also partner with third-party processors. Our network of facilities utilizes, markets and sells products including mulch, compost, soil amendments, and renewable energy.

The recyclable materials processed in our recycling facilities are received from various sources, including third parties and our own operations. In recent years, we have been focused on reducing dependency on market prices for recycled commodities by recovering our processing costs first. In our materials processing business, we have been transitioning our customer base over time from the traditional rebate model, where we paid suppliers for the inbound material, to a fee-for-service model that ensures the cost of processing the recyclable materials is covered along with an acceptable

[**Table of Contents**](#TOC)

margin. With our current fee-for-service model, the pricing for these recyclable materials can either be a charge or "tip fee" when commodity pricing does not cover our cost to process the recyclable materials or a "rebate" when commodity pricing is higher than our processing costs and we are able to share this benefit with the customers generating recyclable materials. In some cases, our pricing is based on fixed contractual rates or on defined minimum per-ton rates. Generally, this pricing also considers the price we receive for sales of processed goods, market conditions and transportation costs. As a result, changes in commodity prices for recycled materials also significantly affect the pricing to our suppliers. Depending on the key terms of the arrangement, these "rebates" are recorded as either operating expenses or a reduction in operating revenues within our Consolidated Statements of Operations. If the key terms result in a charge to the customer, the associated "tip fees" would be recorded as operating revenues within our Consolidated Statements of Operations.

***Renewable Energy***

We develop, operate and promote projects for the beneficial use of landfill gas through our Renewable Energy segment. Landfill gas is produced naturally as waste decomposes in a landfill. The methane component of the landfill gas is a readily available renewable energy source that can be gathered and used beneficially as an alternative to fossil fuel. The U.S. Environmental Protection Agency ("EPA") endorses landfill gas as a renewable energy resource, in the same category as wind, solar and geothermal resources. As of December 31, 2025, we had 103 landfill gas beneficial use projects producing commercial quantities of methane gas at owned or operated landfills. For 62 of these projects, the processed gas is used to fuel electricity generators. The electricity is then sold to public utilities, municipal utilities or power cooperatives. For 24 of these projects, the gas is used at the landfill or delivered by pipeline to industrial customers as a direct substitute for fossil fuels in industrial processes. For 17 of these projects, the landfill gas is processed to pipeline quality RNG and then sold to natural gas suppliers. Additionally, three of these projects are on third-party landfills. The revenues from both WM owned and third-party owned facilities are primarily generated through (i) the sale of captured and converted landfill methane gas; (ii) the sale of RINs under the Renewable Fuel Standard ("RFS") program implemented by the EPA; (iii) sale of Low Carbon Fuel credits designed to stimulate the use of low-carbon fuels and (iv) the sale of energy (electricity and capacity) and associated RECs. Renewable Energy is charged a 15% royalty on net operating revenue from these facilities residing on our active and closed landfills from our Collection and Disposal and Corporate and Other businesses, which is eliminated in consolidation. Additionally, Renewable Energy operates and maintains six third-party landfill beneficial gas use projects in return for service revenue. Our Collection and Disposal and Corporate and Other businesses benefit from these projects as well as 54 additional third-party landfill beneficial gas use projects in the form of royalties.

Renewable Energy converts landfill gas into several sources of renewable energy, which include RNG, electricity, heat and steam. Renewable Energy also generates RINs under the RFS program, other credits under a variety of state programs associated with the use of RNG in our compressed natural gas fleet and RECs associated with the production of electricity. Additionally, we generate and sell credits in Canadian and European markets through the Clean Fuels Regulations and the International Sustainability and Carbon Certification System, respectively. The RINs, RECs and other credits are sold to counterparties who are obligated under various regulatory programs and have a responsibility to procure RINs, RECs and other credits in order to offset their fossil fuel production and imports.

***Healthcare Solutions***

Our Healthcare Solutions segment, through our subsidiary Stericycle, is primarily a business-to-business company providing RWCS and SID services that protect people and brands, promote health and well-being and safeguard the environment. Healthcare Solutions serves customers in the U.S., Canada and Western Europe with solutions to safely manage materials that could otherwise spread disease, contaminate the environment or compromise one's identity. Services provided through our Healthcare Solutions segment includes the following:

*Regulated Waste and Compliance Services*

Healthcare Solutions includes compliance programs and collection, processing, and disposal of regulated and specialized waste, including medical, pharmaceutical and hazardous waste. RWCS are provided to customers in the U.S., Canada, Ireland and the United Kingdom ("U.K.").

[**Table of Contents**](#TOC)

Regulated waste can be defined as any material subject to government-imposed guidelines for handling the material for transportation or disposal. Examples include medical waste, pathological waste, sharps and pharmaceutical waste.

*Collection and Transportation* — The collection process for regulated waste streams begins at the customer location with waste segregation. To assure regulatory compliance, we educate our customers and will not accept material from customers unless it complies with our waste acceptance protocols and is properly stored or packaged in containers that we have either supplied or approved and is appropriately labeled.

Our team members then collect containers at the customer location via our fleet of vehicles. The majority of collected waste is then transported directly to one of our processing facilities or to one of our Healthcare Solutions transfer stations where waste is aggregated until it is transported to a processing facility.

*Processing and Disposal of Regulated Waste* — Upon arrival at a processing facility, containers or boxes of regulated waste undergo a quality control process to verify that they do not contain any unacceptable substances. Any container or box that is discovered to contain unacceptable waste goes through a corrective action process which could include redirecting the waste, returning the waste to the customer and/or notifying the appropriate regulatory authorities. From there, regulated waste is processed using one of several treatments or processing technologies, predominantly at one of our facilities:

● *Autoclaving* — Autoclaving is the primary method of regulated waste treatment. This process relies on steam at high temperature and pressure to kill pathogens and render materials non-infectious. As of December 31, 2025, we operated 42 autoclave facilities in the U.S. and Canada.

● *Alternative Technologies* — We use several different non-incineration alternatives to autoclaves, predominantly outside of the U.S. The processes used by these technologies are similar to autoclaving, as the regulated waste is heated to a specified temperature for a required time to kill the pathogens and render materials non-infectious. Depending on local requirements, the waste may be shredded before or after treatment to render it unrecognizable. As of December 31, 2025, we operated 9 alternative medical waste treatment facilities in the U.S., Ireland and the U.K.

● *Incineration* — While we strive to use alternative, non-incineration methods for treating medical waste, incineration remains a regulatory requirement and/or a best practice in certain geographies or for certain types of medical waste that need to be chemically destroyed. Incineration burns regulated waste at elevated temperatures and reduces it to ash. Incineration reduces the volume of waste, and it is the recommended treatment and disposal option for some types of regulated waste such as anatomical waste, residues from chemotherapy procedures and non-hazardous pharmaceutical waste. Air emissions from incinerators can contain certain byproducts that are subject to federal, state and in some cases, local regulation. In some circumstances, the ash byproduct of incineration may be regulated. As of December 31, 2025, we operated 17 medical waste incinerator facilities in the U.S., Canada and the U.K.

Upon completion of the treatment process, the resulting waste or incinerator ash is transported for disposal in a landfill owned by the Company or a third party. Additionally, in several of our incineration facilities, primarily in the U.K., we use different types of waste-to-energy solutions as part of our processes.

*Secure Information Destruction*

Healthcare Solutions also provides for the collection of personal and confidential information for secure destruction and recycling of sorted office paper. SID services are provided to customers in the U.S., Belgium, Canada, France, Germany, Ireland, Luxembourg, the Netherlands and the U.K.

We leverage a combination of off-site and on-site document destruction methods for one-time and recurring paper shredding. As of December 31, 2025, we operated 99 secure information destruction facilities in the U.S., Canada and Western Europe. Our service offerings leverage cross-cut shredding technology to enhance the security level of destruction and can provide secure chain-of-custody and proof of service. Shredded paper is then sold as sorted office paper.

[**Table of Contents**](#TOC)

***Corporate and Other***

We also provide additional services that are not managed through our operating segments, which are presented in this report as Corporate and Other as they do not meet the criteria to be aggregated with other operating segments and do not meet the quantitative criteria to be separately reported. This includes the activities of our corporate office, including costs associated with our long-term incentive program, expanded service offerings and solutions (such as our investments in businesses and technologies that are designed to offer services and solutions ancillary or supplementary to our current operations) as well as our closed sites.

Included within our Corporate and Other businesses' closed sites are (i) five third-party power generating facilities converting our landfill gas to fuel electricity generators; (ii) two third-party projects delivering our landfill gas by pipeline to industrial customers as a direct substitute for fossil fuels in industrial processes and (iii) two third-party RNG facilities processing landfill gas to be sold to natural gas suppliers in return for a royalty. Additionally, Corporate and Other benefits from a 15% royalty from our Renewable Energy segment based on net operating revenue generated through the sale of RNG, RINs, electricity and capacity, RECs and related environmental attributes from the 17 landfill beneficial use renewable energy projects owned by Renewable Energy on our closed sites, which is eliminated in consolidation.

We continue to invest in businesses and technologies that are designed to offer services and solutions ancillary or supplementary to our current operations. While most of these investments are in the form of minority equity stakes, they can also include joint ventures, joint development agreements or majority equity stakes. The solutions and services include (i) waste collection, processing and recycling; (ii) the development, operation and marketing of waste processing facilities and technologies; (iii) operation of RNG plants and (iv) the development and operation of organic recycling technologies. Furthermore, we continually scout, evaluate and run proof-of-concepts of innovative technologies within our core operations to improve safety, operational efficiencies and customer solutions.

#### Competition
We encounter intense competition from governmental, quasi-governmental and private sources in all aspects of our operations. We principally compete with large national waste management companies, counties and municipalities that maintain their own waste collection and disposal operations and regional and local companies of varying sizes and financial resources. The industry also includes companies that specialize in certain discrete areas of waste management, operators of alternative disposal facilities, companies that seek to use parts of the waste stream as feedstock for renewable energy and other by-products and waste brokers that rely upon haulers in local markets to address customer needs.

Operating costs, disposal costs and collection fees vary widely throughout the geographic areas in which we operate. The prices that we charge are determined locally, and typically vary by volume and weight, type of waste collected, treatment requirements, risk of handling or disposal, frequency of collections, distance to final disposal sites, the availability of airspace within the geographic region, labor costs and amount and type of equipment furnished to the customer. We face intense competition based on pricing and quality of service. We also compete for business based on breadth of service offerings. As companies, individuals and communities look for ways to be more sustainable, we are promoting our comprehensive services that go beyond our core business of collecting and disposing of waste in order to meet their needs.

#### Seasonal Trends
Our financial and operating results may fluctuate for many reasons, 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 operating revenues and volumes typically experience seasonal increases in the summer months that are reflected in second and third quarter revenues and results of operations.

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.

[**Table of Contents**](#TOC)

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.

#### Human Capital Resources

#### Employees
As of December 31, 2025, we had approximately 60,500 full-time employees across the U.S., Canada, Western Europe, and India. Approximately 53,600 employees were located within the U.S. and 6,900 employees were located outside of the U.S. Approximately 8,400 employees were employed in administrative and sales positions with the remainder in operations. Approximately 9,200 of our employees are covered by collective bargaining agreements. Additional information about our workforce can be found in our 2025 Sustainability Report at sustainability.wm.com. Our 2025 Sustainability Report does not constitute a part of, and is not incorporated by reference into, this report or any other report we file with (or furnish to) the SEC, whether made before or after the date of this Annual Report on Form 10-K.

***People First Commitment***

Our People First commitment means knowing that the daily contributions of our team members are what enable us to play a vital role in the communities we serve. Our success depends upon effective leadership, the contributions of each employee and our ability to give them the tools they need to safely execute their roles as well as to develop and excel in their careers. As our industry and workforce evolve, we are focused on our imperatives of keeping our employees safe, being an inclusive employer at all levels of our Company, managing employee turnover, increasing retention, succession planning and development, and supporting employee experience, ongoing cultural integration and knowledge transfer. We regularly focus on these objectives when managing our business.

We strive to be a workplace of choice through competitive pay, comprehensive benefits for long-term financial and personal health and opportunities for growth across our ranks. "We Are WM" is our Employer Value Proposition, grounded in our People First commitment and shared through a framework that enables us to demonstrate that we are (i) investing in our teams by providing comprehensive benefits; (ii) committed to the growth of our team by providing state-of-the-art trainings and our education benefit, Your Tomorrow, as further discussed under *Compensation and Benefits*; (iii) performing essential and meaningful work and (iv) working for a sustainable tomorrow by leaving the world a better place than we found it. Being an employer of choice is critical to our efforts to attract and retain a high-quality workforce, while motivating us to sharpen our focus on our values that help us empower and develop good employees. By promoting from within and offering training and experiential opportunities, we help employees maximize their effectiveness and grow in their careers.

#### Safety as a Core Value
At the Company, safety is a core value, with no compromise. A large number of our employee population work as drivers, heavy equipment operators, technicians and sorters, which are essential jobs that carry inherent risks. For nearly 20 years, we have engaged employees on safety to continually improve our culture and performance. As part of those efforts, in 2023 we developed and implemented a new safety vision for WM, which seeks to ensure that our employees make health and safety the foundation of their work, guiding each step they take. Our safety commitment is to value every voice, protect our communities, and work to enable everyone to get home safe, every day. Employees learn safety best practices through new-hire training, onboarding programs and ongoing training. To build upon lessons learned in training, we conduct structured observations of frontline employees that cover all aspects of our collection and post-collection operations, including driving, loading, unloading, lifting and lowering and arriving prepared for work. In 2022, the Company announced a safety goal focused on reduction of our Total Recordable Incident Rate ("TRIR"), targeting 2.0 annually by 2030, and continued focus on prevention of serious injuries. TRIR measures the number of OSHA recordable injuries occurring per 200,000 hours. Our TRIR as of December 31, 2025 was 3.14, approximately a 3% improvement from 2024. While our overall results in 2025 did not demonstrate significant progress toward the 2030 goal, we continue

[**Table of Contents**](#TOC)

to focus efforts on priority districts and integrating safety culture and reporting throughout operations, including through acquisition activity. We often find that the discipline and culture of the Company benefit acquired businesses. Accordingly, while acquisitions can impact metric performance related to our established goal, we are confident that our programs and processes will continue to reduce incident frequency and severity in our operations in the years ahead. The Company reduced overall TRIR (2.8%), OSHA recordable (5.1%), and Lost Time (4.9%) injuries in 2025 and remains focused on the prevention of serious injuries.

#### Cultivating Belonging
We embrace and cultivate respect, trust, open communications and diversity of thought and people. We are committed to fostering an environment where all team members feel welcomed, valued and seen. Our commitment to a culture of belonging is reflected in the diverse backgrounds of our Board of Directors and senior leadership team and in our overall workforce in the U.S., which is comprised of individuals of all ethnicities and genders. Additional information about our workforce can be found in our 2025 Sustainability Report at sustainability.wm.com. We are proud of what we have been able to achieve so far, and we will continue to strive to further embed a culture of belonging within the Company. To enable us to achieve a workplace where all feel welcomed and valued, we are committed to evaluating our policies, practices and procedures, recruitment and partnerships to ensure that our efforts are fair, sustainable and tied to our business strategy.

***Learning and Development***

We offer expansive learning and development solutions to meet the development needs of our people and support opportunities for growth and improvement. Our talent management strategy is designed to reach employees at all levels. Given the wide variety of employee roles and skill sets in our Company, our training and development programs are varied but generally fall into the following categories: (i) compliance, including Code of Conduct and cybersecurity training; (ii) safety; (iii) environmental excellence; (iv) professional development and leadership and (v) job-specific.

***Compensation and Benefits***

The objective of our compensation and benefit programs is to attract, engage, reward and incentivize valuable employees who will drive the successful execution of our strategy. We pay the full cost to provide employees with short- term disability benefits, long-term disability benefits, basic life insurance for the employee and their dependents, and employee and family assistance benefits. The costs for medical and dental coverage are shared with employees, with the Company paying for a majority of the premium expense. The Company offers other important benefits such as paid vacation and holidays, mental health services, legal services, flexible spending accounts, dependent care assistance, adoption assistance, employee discounts and student loan refinancing services. We also recognize the value of learning beyond the workplace. Our education benefit, Your Tomorrow, makes a contribution toward benefits-eligible employees' tuition for a broad range of four-year college degree programs, as well as programs such as high-school equivalency and other certificate programs and graduate degrees. We also provide plans to help employees save for their future for example, through our 401(k) retirement savings plan. Refer to Note 9 to the Consolidated Financial Statements for additional information on our employee benefit plans.

#### Financial Assurance and Insurance Obligations

#### Financial Assurance
Municipal and governmental waste service contracts generally require contracting parties to demonstrate financial responsibility for their obligations under the contract. Financial assurance is also a requirement for (i) obtaining or retaining disposal site or transfer station operating permits; (ii) supporting certain variable-rate tax-exempt debt and (iii) estimated final capping, closure, post-closure and environmental remedial obligations at many of our landfills. We establish financial assurance using surety bonds, letters of credit, insurance policies, trust and escrow agreements and financial guarantees. The type of assurance used is based on several factors, most importantly: the jurisdiction, contractual requirements, market factors and availability of credit capacity.

[**Table of Contents**](#TOC)

Surety bonds and insurance policies are supported by either (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. Letters of credit generally are supported by our long-term U.S. and Canadian revolving credit facility ("$3.5 billion revolving credit facility") and other credit lines established for that purpose.

#### Insurance
We carry a broad range of insurance coverages, including health and welfare, 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. 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. Our estimated insurance liabilities as of December 31, 2025 are summarized in Note 10 to the Consolidated Financial Statements.

#### Regulation
*Overview*

Our business is subject to extensive and evolving laws and regulations pertaining to environmental protection, health, safety, land use, zoning, transportation, ethical business conduct, data privacy and security, and other related and similar subjects. These laws and regulations are administered by the EPA, Environment and Climate Change Canada ("ECCC"), and various other agencies at the federal, state, provincial, regional and local level in the U.S., Canada and other international jurisdictions in which we operate. Many of these agencies regularly examine our operations to monitor compliance with applicable laws and regulations and have the power to enforce compliance, obtain injunctions or impose civil or criminal penalties in cases of violations.

Our business primarily involves the collection, transport, handling, treatment, destruction, and other processing and management of solid waste, medical waste, controlled substances waste, hazardous waste, organics, and recyclables in an environmentally sound manner. A significant amount of our capital expenditures is related, either directly or indirectly, to compliance with applicable laws and regulations, including environmental protection measures. Our November 2024 acquisition of Stericycle increased our exposure to international jurisdictions, primarily Western Europe, and we are subject to laws and regulations in the U.S. and internationally concerning transportation, management and disposal or destruction of medical waste streams, including regulations that govern the definition, generation, segregation, handling, packaging, transportation, treatment, storage and disposal or destruction of medical waste and controlled substances waste, along with extensive recordkeeping and documentation requirements. Additionally, our secure information destruction services are subject to laws and regulations regarding proper handling and protection of personal and confidential information.

There are costs associated with siting, design, permitting, construction, operating, monitoring, site maintenance, corrective actions, financial assurance and closure and post-closure obligations at our facilities. In connection with the acquisition, development or expansion of a waste management or disposal facility, recycling facility, compost facility, transfer station, processing facility, or landfill gas-to-energy facility, or the transport, handling, treatment and disposal or destruction of various waste streams, we must often spend considerable time, effort and money to obtain and maintain required permits and approvals. There are no assurances that we will be able to obtain or maintain permits or other required governmental approvals. Once obtained, permits are subject to renewal, modification, suspension or revocation by the issuing authority. Permit issuance or renewal may also be subject to public participation or other governmental reviews and may be subject to challenges and delays. Compliance with current regulations and future requirements could require us to make significant capital and operating expenditures. However, most of these expenditures are made in the normal course of business and do not place us at a competitive disadvantage.

[**Table of Contents**](#TOC)

The regulatory environment in which we operate is influenced by changes in governmental administrations and leadership. The current administration has called for, and undertaken, substantial changes to areas of foreign trade policy and is generally in favor of reducing regulation, including environmental regulation. The impact and timing of these shifts in regulatory policy impacting our industry and our Company remain uncertain, as many are subject to ongoing litigation and agency review. Further, state and municipal governments may impose additional regulatory duties in response to such shifts in federal policy, which could lead to a patchwork of regulatory obligations across the U.S. for our industry and our Company. Reduction of regulation may have a favorable impact on our operating costs, but the extensive environmental regulation applicable to our industry is also a barrier to rapid entry that benefits our Company. Moreover, the risk reduction provided by appropriate regulation is valuable to our customers and the communities we serve. Significant restrictions and tariffs on foreign trade could have a negative impact on our recycling export business and our cross-border commerce, particularly with Canada, and could increase the cost of certain equipment and other materials used in our operations that we procure from outside the U.S., including our trucks and certain equipment used to implement our sustainability growth strategy. It is likely that some policies adopted by the administration will benefit us and others will negatively affect us.

In 2024, the U.S. Supreme Court issued a number of decisions that will affect the future of federal regulation, including *Loper Bright Enterprises v. Raimondo*. The *Loper* decision overturned the *Chevron* doctrine, which had held that a court must give deference to a regulatory agency's reasonable interpretation of an ambiguous statute the agency implements. The full impact of that decision is not yet known, but at a minimum, our operations could face increased regulatory uncertainty in connection with legal challenges to agency actions and rulemakings impacting our industry.

#### Federal Regulation
Certain key U.S. federal statutes affecting our business are summarized below:

● The Resource Conservation and Recovery Act of 1976 ("RCRA"), as amended, regulates handling, transporting and disposing of hazardous and non-hazardous waste and delegates authority to states to develop programs to ensure the safe disposal of solid waste. Landfills are regulated under Subtitle D of RCRA, which sets forth minimum federal performance and design criteria for solid waste landfills, and Subtitle C of RCRA, which establishes a federal program to manage hazardous wastes from cradle to grave. These regulations are typically implemented by the states, although states can impose requirements that are more stringent than the federal standards. We incur costs in complying with these standards in the ordinary course of our operations.

● The Comprehensive Environmental Response, Compensation and Liability Act of 1980 ("CERCLA"), as amended, which is also known as Superfund, provides for federal authority to respond directly to releases or threatened releases of hazardous substances into the environment that have created actual or potential environmental hazards. CERCLA's primary means for addressing such releases is to impose strict liability for cleanup of disposal sites upon current and former site owners and operators, generators of the hazardous substances at the site and transporters who selected the disposal site and transported substances thereto. Liability under CERCLA is not dependent on the intentional release of hazardous substances; it can be based upon the release or threatened release of hazardous substances, even resulting from lawful, unintentional and attentive action, as the term is defined by CERCLA and other applicable statutes and regulations. The EPA may issue orders requiring responsible parties to perform response actions at sites, or the EPA may seek recovery of funds expended or to be expended in the future at sites. Liability may include contribution for cleanup costs incurred by a defendant in a CERCLA civil action or by an entity that has previously resolved its liability to federal or state regulators in an administrative or judicially-approved settlement. Liability under CERCLA could also include obligations to a potentially responsible party ("PRP") that voluntarily expends site clean-up costs. Further, liability for damage to publicly-owned natural resources may also be imposed. We are subject to potential liability under CERCLA as an owner or operator of facilities at which hazardous substances have been disposed and as a generator or transporter of hazardous substances disposed of at other locations.

● The Federal Water Pollution Control Act of 1972, as amended, known as the Clean Water Act, regulates the discharge of pollutants into streams, rivers, groundwater, or other surface waters from a variety of sources, including solid and hazardous waste disposal sites. If our operations discharge any pollutants into federally protected surface waters, the Clean Water Act requires us to apply for and obtain discharge permits, conduct sampling and monitoring, and, under certain circumstances, reduce the quantity of pollutants in those discharges. The EPA also requires landfills and other waste-handling facilities to obtain storm water discharge permits, and

[**Table of Contents**](#TOC)

if a landfill or other facility discharges wastewater through a sewage system to a publicly-owned treatment works, the facility must comply with discharge limits imposed by the treatment works. Further, before the development or expansion of a landfill can alter or affect certain "wetlands," a permit may have to be obtained providing for mitigation or replacement wetlands. The Clean Water Act provides for civil, criminal and administrative penalties for violations of its provisions.

● The Clean Air Act of 1970, as amended, provides for federal, state and local regulation of the emission of air pollutants. Many of our operations, including many municipal solid waste ("MSW") landfills and landfill gas-to-energy facilities, are subject to regulations implemented under the Clean Air Act, including new source performance standards, emission guidelines and national emission standards for hazardous air pollutants. These regulations impose performance standards to minimize air emissions from regulated MSW landfills, subject those landfills to certain operating permit requirements under Title V of the Clean Air Act and, in many instances, require installation of landfill gas collection and control systems to control emissions or to treat and utilize landfill gas on- or off-site. Our vehicle fleet also must adhere to regulations implemented under the Clean Air Act, which authorizes the EPA to mandate controls on air pollution from mobile sources.

● The Occupational Safety and Health Act of 1970, as amended, establishes certain employer responsibilities, including maintenance of a workplace free of recognized hazards likely to cause death or serious injury, compliance with standards promulgated by the Occupational Safety and Health Administration, and various reporting and record keeping obligations as well as disclosure and procedural requirements. Various standards for notices of hazards, personal protective equipment, safety in excavation and demolition work, exposure to bloodborne pathogens, and the handling of asbestos, may apply to our operations.

● The Department of Transportation and the Occupational Safety and Health Administration, along with other federal agencies, have jurisdiction over certain aspects of hazardous materials and hazardous waste, including safety, movement and disposal. Certain waste (including medical waste) is subject to roadside inspections that have a cumulative effect on our compliance history and require us to remain in good standing so as not to jeopardize certain permits. Various state and local agencies with jurisdiction over disposal of hazardous and medical waste may seek to regulate movement of such materials in areas not otherwise preempted by federal law.

● Our service offerings for the collection, treatment, disposal and destruction of controlled substances waste and medical waste, from both the healthcare industry and individual consumers, are subject to numerous laws and regulations issued by various regulatory agencies, including the U.S. Drug Enforcement Administration ("DEA"). These regulations typically require our facilities to obtain licenses or registrations, and meet certain other requirements in order to collect, transport, treat and dispose of controlled substances. These regulations include significant requirements for security, recordkeeping and reporting. Registrations and licenses must be kept current, or periodically renewed, and facilities may be subject to inspection or enforcement.

Our operations are primarily in the U.S.; however, Canada and other countries in which we operate have various environmental, safety, health, transportation and materials handling laws and regulations that we must comply with in the ordinary course of our business.

*State, Provincial, Regional and Local Regulations*

There are also various state, provincial, regional and local regulations, in the U.S. and internationally, that affect our operations and may require a specific operating plan. Many jurisdictions in which we operate have their own laws and regulations governing solid waste disposal, including for hazardous wastes, medical wastes and controlled substances wastes; water and air pollution; and, in most cases, releases and cleanup of hazardous substances and liabilities for such matters. Many governmental organizations have also adopted regulations governing the design, operation, maintenance and closure of landfills, transfer stations, incineration facilities and processing facilities, and laws governing where recyclable materials can be sold.

Our landfill operations are affected by the increasing preference for alternatives to landfill disposal. Many state and local governments mandate recycling and waste reduction at the source and prohibit the disposal of certain types of materials at landfills, such as recyclable materials (cardboard, bottles and cans), yard waste, food waste and electronics.

[**Table of Contents**](#TOC)

The number of governments with recycling and diversion requirements and disposal bans continues to grow, while the logistics and economics of recycling or processing many of these items remain challenging. In addition, regulations requiring the diversion of organic wastes away from landfills could have the effect of decreasing the amount of landfill gas produced over time in our landfills, negatively impacting our Renewable Energy segment.

Various states have enacted, or are considering enacting, laws that restrict or discourage the disposal of solid waste generated outside the state. While laws that overtly discriminate against out-of-state waste have been found to be unconstitutional, some laws that are less overtly discriminatory have been upheld in court. From time to time, the U.S. Congress has considered legislation authorizing states to adopt regulations, restrictions, or taxes on the importation of out-of-state or out-of-jurisdiction waste. Additionally, several state and local governments have enacted "flow control" regulations, which attempt to require that all waste generated within the state or local jurisdiction be deposited at specific sites, which has been upheld by the U.S. Supreme Court for waste directed to facilities owned by the local government. The U.S. Congress' adoption of legislation allowing restrictions on interstate transportation of out-of-state or out-of-jurisdiction waste or certain types of flow control, or courts' interpretations of interstate waste and flow control legislation, could adversely affect our solid waste, hazardous waste, medical waste and controlled substances management services.

Many governmental organizations have enacted "fitness" laws that allow the agencies that have jurisdiction over waste services contracts or permits to deny or revoke these contracts or permits based on the applicant's or permit holder's compliance history. Some governmental organizations also consider the compliance history of the parent, subsidiaries or affiliated companies, in addition to the applicant or permit holder. These laws authorize the agencies to make determinations of an applicant's or permit holder's fitness to be awarded a contract to operate, and to deny or revoke a contract or permit because of unfitness, unless there is a showing that the applicant or permit holder has been rehabilitated through the adoption of various operating policies and procedures put in place to assure future compliance with applicable laws and regulations. While fitness laws can present potential increased costs and barriers to entry into market areas, these laws have not, and are not expected to have a material adverse impact on our business as a whole.

The EPA does not regulate medical waste at the federal level, with some limited exceptions, resulting in a lack of uniformity of applicable laws and regulations. States have adopted their own regulations related to the handling, treatment and storage of medical waste, with many states following requirements similar to the Medical Waste Tracking Act of 1988, a U.S. federal law concerning disposal of biological material that expired in 1991. Other states have placed medical waste regulations within solid waste regulations. Further, while the Canadian Council of Ministers of the Environment has promulgated the *Guidelines for the Management of Biomedical Waste in Canada*, these are not enforceable unless adopted by provincial legislation or municipal by-laws, and local by-laws may be more stringent than such guidelines.

*Recent Developments and Focus Areas in Policy and Regulation*

*Climate and Sustainability*

Certain jurisdictions are taking action to reduce greenhouse gas ("GHG") emissions through a broad range of climate policies. Landfills are one of the focal points for advancing climate-related goals, and we are actively working with policymakers to promote recognition of the significant reductions in GHG emissions that our industry already has achieved and the work being done to further measure and reduce emissions, the challenges associated with quantifying landfill emissions precisely, and the role of our sector in providing an essential, and highly regulated, public service.

We are closely monitoring the evolving capabilities of ground, aerial and satellite-based methane detection and monitoring systems and conducting our own research at several landfills to assess accuracy and reliability of various methane measurement technologies for applicability to our operations. We also continue to expand our work with various private and government entities employing such technologies at our sites, and we are actively engaged with the EPA, the ECCC, state agencies, nongovernmental organizations and environmental stakeholders on the implications of the changing landscape for the waste industry and potential future regulation. Continued dialogue, engagement and collaboration with these regulatory agencies will be important, as the EPA, the ECCC and several states, including California and Colorado, are evaluating landfill emissions standards that may require the application of various emerging methane measurement technologies and plan to develop methods and standards for such measurement technologies. While we cannot predict

[**Table of Contents**](#TOC)

what regulations will result from these initiatives, these developments could result in increased compliance costs and adversely affect our operations. Specifically, these various regulatory actions could result in changes to how we have historically reported GHG emissions and may result in increases in such emissions reported for our operations. For example, in August 2024, the EPA released revised emission factors for the reporting of methane emissions from landfills that would, amongst other matters, result in increased reported emissions from flares and other equipment and processes. Industry groups have filed legal challenges to the EPA's updated emission factors, and the EPA granted the industry's petition for reconsideration. In September 2025, the EPA announced a proposed rule to significantly revise the Greenhouse Gas Reporting Program. The proposal would eliminate reporting requirements for numerous source categories, including landfills. This uncertainty regarding the status of the federal reporting program could result in increased state-level GHG reporting requirements.

In light of customer demand, we have identified strategic business opportunities to provide our public and private sector customers with sustainability-related solutions intended to have the potential to reduce GHG emissions across their respective businesses. We assess customer demand for and opportunities to develop waste services with potential to avoid lifecycle emissions, such as waste reduction, increased recycling, composting and conversion of landfill gas and discarded materials into renewable energy. Demand and willingness to pay premium prices for recycled materials or enhanced sustainability solutions can fluctuate based on economic conditions, consumer preferences and trends. We use estimated lifecycle emissions assessments in evaluating potential new services and in establishing the value proposition that makes us attractive as an environmental service provider. We are active in support of public policies that encourage development and use of lower carbon energy and waste services that can lower lifecycle carbon footprints. We understand the importance of broad stakeholder engagement in these endeavors and actively seek opportunities for public policy discussion on how materials management practices can be more sustainable. In addition, we work with stakeholders at the federal, state, and provincial level in support of legislation that encourages production and use of renewable, lower-carbon fuels and electricity.

The nature, scope, and complexity of matters that our Company must assess, quantify and disclose are expanding due to current, proposed, and recently enacted governmental reporting requirements pertaining to sustainability and climate-related risks and other topics. Such topics include water usage, waste production, labor, human capital, cybersecurity, privacy and risk oversight. For example, in September 2024, the California Governor signed into law amendments to the 2023 California Climate Corporate Data Accountability Act and the Climate-Related Financial Risk Act, which among other things, requires the disclosure of Scope 1, 2, and 3 GHG emissions and other climate-related financial risks consistent with the framework established by the Task Force on Climate-Related Financial Disclosures. We potentially will be required to begin making disclosures of our Scope 1 and 2 GHG emissions in compliance with certain of these requirements in 2026, and Scope 3 GHG emissions disclosures will be required beginning in 2027. Additional U.S. states are in various stages of considering adoption of similar climate-related disclosure requirements. While the SEC voluntarily stayed implementation of its climate related disclosure rules indefinitely, and voted to end its defense of those rules in March 2025, the state-level and other similar laws and regulations could result in increased compliance costs and affect the results of our operations and financial position. Such laws and regulations could also increase our litigation risks or may increase risks related to our reputation or goodwill, as we cannot predict how disclosures under these laws may be perceived or interpreted by our customers and stakeholders. Methodology and timelines for mandatory reporting requirements may be inconsistent with requirements enacted by other governmental entities, including with respect to measuring emissions and requiring a determination of "materiality" that may differ from traditional disclosure requirements under U.S. federal securities laws. Such inconsistency could further increase costs and divert management time and attention.

Our industry faces challenges to implement these rapidly developing disclosure requirements, as well as the risk of enforcement actions by governmental and regulatory agencies for noncompliance. Significant expenditures and commitment of time by management, employees and consultants is involved in developing, implementing and overseeing policies, practices, additional disclosures and internal controls related to environmental and sustainability risk and performance. Public statements with respect to sustainability matters are subject to heightened scrutiny related to the risk of potential "greenwashing," *i.e.*, allegations of misleading information or false claims overstating potential sustainability benefits made by governmental authorities, non-governmental organizations and other private actors.

Consistent with our Company's long-standing commitment to sustainability and environmental stewardship, we have published our 2025 Sustainability Report, providing details on our sustainability-related performance and outlining

[**Table of Contents**](#TOC)

progress towards our 2030 sustainability goals. The annual Sustainability Report conveys the strong linkage between the Company's sustainability goals and our growth strategy, inclusive of the expansion of the Company's Recycling Processing and Sales and Renewable Energy segments. The information in this report can be found at sustainability.wm.com but it does not constitute a part of, and is not incorporated by reference into, this Annual Report on Form 10-K. The Company also participates in a number of voluntary reporting programs and frameworks that provide further transparency on our commitment to sustainability.

*PFAS*

Federal and state governments have increased their focus on efforts to safeguard communities from the potentially harmful effects associated with per- and polyfluoroalkyl substances ("PFAS"). PFAS are a large group of chemicals that have been used in industrial and consumer products since the 1940s, including in products as diverse as carpets, paints and stains, water-resistant clothing and fabrics, nonstick cookware, food packaging, and firefighting chemicals. Possible human health effects of exposure to certain PFAS compounds may include low infant birth weights, immune system impacts, or cancer.

There are a number of risks related to PFAS that could impact our business, and the EPA has prioritized PFAS-related issues in recent years. For example, in 2021, the EPA released its PFAS Strategic Roadmap, providing a high-level overview of activities that the agency intends to take to safeguard public health, protect the environment and hold polluters accountable. These actions include establishing drinking water standards, evaluating landfill discharges of PFAS in leachate, finalizing new risk assessments and test procedures and updating guidance on PFAS disposal and destruction options. In April 2024, the EPA finalized the designation of two PFAS compounds (perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS)) as hazardous substances under CERCLA. We are actively working with both Congress and the EPA to provide landfills and other essential public services with relief from CERCLA liability and instead hold accountable manufacturers and heavy users of these compounds. Without such relief, we may face increased exposure to remediation and litigation costs associated with properties that the EPA may designate as CERCLA sites due to the presence of PFAS. Additionally, the EPA is pursuing legally enforceable maximum contaminant levels, as well as non-enforceable maximum contaminant level goals, for PFAS compounds in drinking water. We expect that there could be continued efforts to regulate or impose liability with respect to PFAS at the federal level. At the state level, an increasing number of jurisdictions have enacted new drinking water, surface water and/or groundwater limits for various PFAS compounds, which has led to a patchwork of PFAS standards across the U.S. Compliance with new and future state and federal PFAS standards is anticipated to result in additional expense to the Company, but such standards are also anticipated to present potential business opportunities in the area of PFAS management, treatment and disposal.

*Recycling; Foreign Import and Export Regulations and Material Restrictions*

Regulations affecting, and in some cases restricting, the international flow of certain recyclables have led to a reduction in export activity for such recyclables, as well as higher quality requirements, and higher processing costs. We do not ship plastics collected on our residential recycling routes and processed at our single stream recycling facilities to locations outside of North America, except in very limited circumstances when no other commercially viable domestic markets are available; however, current and developing international regulations may limit our ability to export other commodities, including certain plastics. Additionally, the current U.S. presidential administration has called for, and undertaken, substantial changes to foreign trade policy. Significant restrictions and tariffs on foreign trade have a negative impact on our recycling export business, including decreasing paper mills' demand for recycled corrugated cardboard used in packaging, which can constrict availability of counterparties and negatively impact commodity prices, and increase the cost of certain equipment and other materials used in our operations that we procure from outside the U.S., including certain equipment used to implement our sustainability growth strategy.

Prices and demand for recyclables fluctuate. We have discussed our sustainability growth strategy that includes significant investments in our recycling business to increase automation and reduce labor dependency. Such investments are also targeted at addressing increases in regulatory- and customer-driven quality requirements for commodities. These investments increase our exposure to commodity price fluctuations. We mitigate some of the effects of price fluctuation through the contract terms pursuant to which we sell commodities, such as floor pricing. Additionally, regulation, tariffs, international trade policies or other initiatives, including extended producer responsibility regulations, minimum recycled

[**Table of Contents**](#TOC)

content laws, container deposit laws, or regulations addressing climate change or GHG emissions, may impact supply and demand of material, or increase operating costs, which could impact the profitability of our recycling operations.

With a heightened awareness of the global problems caused by plastic waste in the environment, and actual or perceived risks for human health, many governments have passed ordinances banning certain types of plastics from sale or use. The most common materials banned include plastic bags and straws, polystyrene plastic and some types of single use packaging. These bans have resulted in increased pressure by manufacturers for our recycling facilities to accept a broader array of materials in curbside recycling and composting programs to alleviate public pressures to ban the sale of those materials. However, with no or limited viable end markets for many of these materials, we and other recyclers are working to educate and remind customers of the need for end market demand and economic viability to support the inclusion of certain materials in recycling programs.

*Extended Producer Responsibility*

Regulations establishing extended producer responsibility ("EPR") are being considered or implemented in many places around the world, including in certain states in the U.S. and provinces and territories in Canada. EPR regulations are designed to place either partial or total responsibility on producers of consumer-packaged goods and other products to fund the post-use life cycle of the products and packaging they create. Along with the funding responsibility, producers may be required to undertake additional responsibilities, such as taking over management of local recycling programs by taking back their products from end users or managing the collection operations and recycling processing and marketing infrastructure. During periods of economic difficulty, governmental entities have increased their interest in implementing EPR regulations to reduce municipal spending on recycling programs. There is no federal law establishing EPR in the U.S. or Canada; however, governments could take, and in some cases have taken, steps to implement EPR regulations for packaging, including traditional recyclables such as cardboard, bottles and cans. If wide-ranging EPR regulations or other recycling-related regulations like container deposit laws are widely adopted, they could significantly impact the waste, recycling and other streams we manage, including with respect to quality and volume, how we operate our business, including contract terms and pricing, and the profitability of our recycling facilities. At the same time, concerns regarding price and affordability have led some jurisdictions to scale back previously enacted EPR requirements, creating uncertainty for long-term planning. Lawsuits have been filed in certain jurisdictions, contesting the constitutionality of certain programs, and the U.S. Department of Justice has indicated that state EPR laws may be among those subject to constitutional review. Deregulatory rulings or changes in program requirements in jurisdictions where we have adapted to meet customer demand may impact our operations, financial condition or result of operations.

EPR implementation also involves new operational requirements and information-sharing obligations that affect how recycling programs are managed. Compliance with EPR laws often requires us to provide detailed operational data to state agencies, producer responsibility organizations and their consultants in connection with needs assessments and tracking of material recyclability. This includes sharing information that is typically considered competitively sensitive. Where feasible, we enter into non-disclosure agreements to safeguard such information.

*Tax Legislation*

On July 4, 2025, President Trump signed the One Big Beautiful Bill Act ("OBBBA") into law. We have evaluated the business tax provisions in the legislation, none of which had a material impact on our effective tax rate. However, we had a beneficial impact to cash taxes related to bonus depreciation.

The OBBBA also reaffirmed and extended various tax-related provisions included in the Inflation Reduction Act of 2022 (the "IRA") of relevance to the company, including with respect to tax incentives for investments in renewable energy production, carbon capture and other climate actions. Given the complexity and uncertainty around the administration's implementation of certain tax credits, we continue to analyze this area to identify and quantify potential opportunities and applicable benefits included in the legislation. We believe that the production tax credit incentives for investments in renewable energy and carbon capture, as reaffirmed and expanded by the OBBBA, may result in an incremental benefit to the Company, although at this time, the anticipated amount of such benefit has not been quantified due, in part, to the lack of regulatory guidance.

[**Table of Contents**](#TOC)

*Investment in Natural Gas Vehicles and Infrastructure*

We operate a large fleet of natural gas vehicles, and we plan to continue to invest in these assets for our collection fleet. Natural gas fueling infrastructure is not yet broadly available in the U.S. and Canada; as a result, we have constructed and operate natural gas fueling stations, some of which also serve the public or pre-approved third parties. There is increasing pressure to reduce the use of fossil fuel in the heavy-duty truck industry, and some regulatory bodies are pursuing requirements for using alternative engine technology, such as electric powered vehicles, rather than natural gas or diesel vehicles. This is resulting in regulatory actions to advance the adoption of zero-emission vehicles and a shift away from tax incentives and grants for natural gas trucks and RNG infrastructure. For example, in April 2024, the EPA established new GHG emissions standards applicable to heavy-duty vehicles that rely on increased deployment of electric vehicles to meet declining emissions targets; however, the current administration has signaled its intent to withdraw these regulations. California also has been active in pursuing policies promoting vehicle electrification, despite U.S. Congressional and presidential administration efforts to push back on the state's electrification agenda. The full impact of these standards and regulations is uncertain, as several of the specific regulations are the subject of legal challenge and could impact our long-term vehicle fleet strategies.

Current options for heavy-duty electric powered vehicles lack sufficient range, recharging infrastructure and efficiency and proven experience for our operations, but we are proactively engaging in pilots of electric powered heavy-duty vehicles and anticipate that we could redirect future planned capital investments in our fleet toward these assets when the vehicles prove economically and operationally viable. We also are actively working with policymakers to help them understand the challenges involving the electrification of heavy-duty collection vehicles. If regulation requires widespread adoption of electric powered vehicles before the technology improves, we may suffer operational inefficiencies and incur higher operating costs. Regulation mandating an accelerated transition to electric powered vehicles would increase our cost to acquire vehicles needed to service our customers, and capital investment required to establish sufficient charging infrastructure could be significant. Additionally, the investments we have made in an industry-leading natural gas fleet and infrastructure could be impaired. Tax incentives and grants that advance the adoption of zero-emissions vehicles and lead to a shift away from natural gas trucks and RNG infrastructure would likely also negatively impact our investments in RNG production facilities.

*Renewable Energy*

In recent years, we have discussed our sustainability growth strategy that includes significant planned and ongoing investments in our Renewable Energy segment. We have invested, and continue to invest, in facilities to capture methane produced from the Company's landfills and process it into RNG and electricity. RNG produced from our landfills constitutes a significant source of fuel allocated to our natural gas collection vehicles. The primary drivers of renewable fuel development at our landfills are tax policies, such as federal tax credits for investments in RNG production under the IRA and OBBBA, and federal and state incentive programs, such as the federal RFS program, California Low Carbon Fuel Standard and similar state programs that promote the production and use of renewable transportation fuels. At the federal level, oil refiners and importers are required through the RFS program to blend specified volumes of various categories of renewable transportation fuels with gasoline or buy credits, referred to as RINs, from renewable fuel producers. Many of our facilities are EPA-registered producers of transportation fuel making compressed and liquefied RNG from landfill biogas, which qualifies as a cellulosic biofuel under the RFS program. The Company has invested, and continues to invest, in facilities that capture and process landfill gas into RNG so that we can participate in the RFS program, and the Company has grown and stated its intention to continue to grow its asset base to increase its RNG production.

RINs prices generally respond to regulations enacted by the EPA, as well as fluctuations in supply and demand. The value of the RINs is set through a market established by the RFS program, which market has historically been volatile. Prior to 2022, the EPA had promulgated rules on an annual basis establishing refiners' obligations to purchase RNG and other cellulosic biofuels under the RFS program, which introduced a level of uncertainty into the renewable fuels and RINs market. However, in 2023, the EPA issued a rule establishing biofuel blending volumes under the RFS program for compliance years 2023 through 2025. The rule reflected the outsized role of biogas under the program, delivered on many reforms that benefit the solid waste sector, and recognized the continued growth of the market for RNG in vehicle applications. The current U.S. presidential administration, meanwhile, revisited and retroactively lowered the 2024 blending volumes, has proposed to revisit and lower the 2025 standards, has proposed low volumes for compliance years

[**Table of Contents**](#TOC)

2026 and 2027 and departed from the previous administration in granting small refinery exemptions from RFS program requirements. We do not yet know how these changes may impact the demand for renewable fuels and the value of RINs. In an effort to mitigate against such risk and stabilize our RNG portfolio, we are pursuing long-term RNG sales transactions in the voluntary market. We continue to advocate for policies that could reduce the potential for volatility in the RINs market and ensure long-term stability for renewable transportation fuels, as changes in the RINs market or the structure of the RFS program can and has impacted the financial performance of our facilities. We are closely working with state policymakers and non-governmental stakeholders to understand the role of RNG as a renewable energy resource and in delivering GHG reductions.

The Company's sustainability growth strategy also is informed by the increased adoption of state and Canadian clean fuel standard programs, utility policies, and voluntary market demand for RNG in transportation and industrial applications. Clean fuel standard programs, originally developed in California and subsequently adopted in Oregon, Washington, and New Mexico, establish annual carbon intensity benchmarks for transportation fuels that decrease over time. A similar program has been adopted in Canada under the Clean Fuel Regulations. These programs operate similar to the RFS program in that certain regulated parties purchase credits from fuel producers, including RNG producers, to meet their carbon intensity obligations. Like RINs, clean fuel standard program credit values can fluctuate with policy and market dynamics. As such, we are advocating for existing programs to adopt measures to promote stability in credit pricing and for other states to adopt similar programs that incentivize the growth in RNG. We also are working closely with stakeholders to encourage the voluntary market for RNG demand, including utility RNG procurement programs, and sustainability protocols, as companies and other customers increasingly look to reduce their GHG emissions profiles. However, these state and voluntary programs may be altered, paused, or otherwise revoked by the applicable governmental authorities or as result of legal challenges.

*Community Engagement – Environmental Justice*

Certain governmental bodies are in various stages of adopting or considering the adoption of requirements for environmental justice reviews as part of certain permitting decisions. These policies generally require permitting agencies to give heightened attention to a project's potential to disproportionately impact low-income and minority communities and to proactively plan for community engagement. Environmental justice and community consultation considerations are also being increasingly adopted beyond permitting actions; for example, in rulemaking and enforcement priorities. Our Company supports policies seeking to advance high standards of environmental performance and the fair treatment of people of all races, cultures, and incomes, and we continue to proactively engage with local communities. We are actively monitoring regulatory developments in this area, particularly with respect to permitting, as additional conditions imposed on permitting decisions could increase the time and cost involved to pursue and maintain necessary authorizations.

*Privacy and Information Security Regulation*

Various U.S. and international laws and regulations related to data privacy, the protection of confidential information and secure information destruction services apply to our business. Applicable laws require businesses to provide notice under certain circumstances to individuals and/or regulators where personal information has been disclosed in a data breach. Regulatory enforcement action concerning privacy and security is generally increasing, including significant fines imposed by regulators. Secure handling and disposal of waste that may contain sensitive information may be subject to heightened privacy requirements, and in the event of a breach, could result in regulatory penalties or wider enforcement action, reputational harm, and financial liabilities.

**Item 1A. *Risk Factors.*** 

Our business, financial condition and results of operations are subject to numerous risks and uncertainties, some of which are not presently known or not currently believed to be material. You should carefully consider the following risk factors in conjunction with Item 7. *Management's Discussion and Analysis of Financial Condition and Results of Operations* and Item 8. *Financial Statements and Supplementary Data*.

**Strategy and Operational Risks**

***If we fail to implement our business strategy, our financial performance and our growth could be materially and adversely affected.***

Our future financial performance and success are dependent in large part upon our ability to implement our business strategy successfully. Implementation of our strategy will require effective management of our operational, financial and human resources and will place significant demands on those resources. See Item 1. *Business* for more information on our business strategy. There are risks involved in pursuing our strategy, including the following:

● Our employees, customers or investors may not embrace and support our strategy.

● A key element of our strategy is yield management through focus on price leadership, which has presented challenges to keep existing business and win new business at reasonable returns. Our unwillingness to pursue lower margin volumes may negatively affect our cash flows or results of operations.

● We may be unsuccessful in implementing our technology-led automation and optimization strategy and other improvements to operational efficiency and such efforts may not yield the intended result.

● We may not be able to maintain cost savings achieved, including through our automation and optimization or acquisition integration efforts, due to inflationary cost pressures or otherwise.

● Execution of our growth strategy, including acquisitions and expansion of operations, has caused, and may in the future cause, us to incur substantial additional indebtedness, which may divert capital away from our traditional business operations and other financial plans.

● Expansion of our Recycling Processing and Sales and Renewable Energy segments may introduce additional compliance and regulatory risks and additional volatility to our financial performance.

● Our ability to make strategic acquisitions depends on our ability to identify desirable acquisition targets, negotiate advantageous transactions despite competition for such opportunities, fund such acquisitions on favorable terms, obtain regulatory approvals and realize the benefits we expect from those transactions.

● Acquisitions, investments and/or new service offerings or lines of business may not increase our earnings to the extent or in the timeframe anticipated, or at all, due to complexities or difficulties operating in new markets or providing new service offerings or lines of business, failure of technologies to perform as expected, failure to achieve targeted revenue growth or market expansion, inability to manage costs within budget, integration issues, or regulatory issues and compliance costs, among others, and we may experience issues successfully integrating acquisitions into our internal controls, operations, and/or accounting systems.

● Integration of acquisitions and/or new services offerings or lines of business, such as our Healthcare Solutions segment, and additional expansion outside of North America, results in our business being subject to new regulations, greater exposure to risk of inadvertent noncompliance and additional compliance costs.

● Liabilities associated with acquisitions, including ones that may exist only because of past operations of an acquired business, may prove to be more difficult or costly to address than anticipated, and businesses or assets we acquire may have undisclosed liabilities, despite our efforts to minimize exposure to such risks through due diligence and other measures.

In addition to the risks set forth above, implementation of our business strategy could be affected by other factors beyond our control, such as increased competition, legal developments, government regulation, global geopolitical instability, general economic conditions, increased operating costs and changes in industry trends. Implementation of our strategy may not improve our operating results to the extent we anticipate, or at all.

[**Table of Contents**](#TOC)

***We may not realize the strategic benefits, revenue and earnings growth, or cost synergies anticipated from the Stericycle acquisition.***

The acquired Stericycle business, which is now presented as our Healthcare Solutions segment, is subject to numerous risks and uncertainties such as decreases in the volume of medical waste and controlled substances wastes or personal and confidential information collected from customers; disruptions resulting from deployment of operational or technological systems, including with respect to Healthcare Solution's enterprise resource planning ("ERP") system and related billing and collection issues and delays; customer loss resulting from frustration due to billing or service issues; delayed revenue growth from planned pricing increases due to factors including customer retention, stabilization of customer data engagement systems and processes, and more prolonged development of market and customer-specific insights than initially planned; changing market conditions in the healthcare industry; competition and demand for services for the medical waste, controlled substances waste and secure information destruction industries; commodity price volatility; changes in regulation of the collection, transportation, treatment and disposal or destruction of medical waste and controlled substances waste or the proper handling and protection of personal and confidential information; the level of government enforcement of regulations governing medical waste and controlled substances waste collection and treatment or the proper handling and protection of personal and confidential information; and the outcome of pending, future or settled litigation or investigations. If we are unsuccessful in achieving financial and operational targets and implementing the Healthcare Solutions business strategy, it could negatively impact our realization of benefits from the acquisition, as well as our stock price and our future business and financial results.

The benefits that are expected to result from our acquisition of Stericycle also depend, in part, on our ability to realize anticipated cost synergies. Our success in realizing these benefits and cost synergies, and the timing of this realization, depends on the successful integration of the Stericycle business. The acquisition of Stericycle may not result in realization of the benefits and cost synergies that we currently expect, and we cannot guarantee that these benefits and cost synergies will be achieved within anticipated time frames. Additionally, we have, and may continue to, incur substantial expenses in connection with the integration of the Stericycle business, which may exceed expectations and offset certain benefits.

***Our operations must comply with extensive existing regulations, and changes in regulations, including with respect to emerging contaminants and extended producer responsibility, can restrict or alter our operations, increase our operating costs, increase our tax liabilities, reduce revenues, or require us to make additional capital expenditures.***

Stringent government regulations at the federal, state, provincial and local level in the U.S. and Canada, as well as other international jurisdictions where we operate, have a substantial impact on our operations, and compliance with such regulations is costly. See Item 1. *Business – Regulation* for additional information. Many complex laws, rules, orders and interpretations govern environmental protection, health, safety, land use, zoning, transportation, ethical business conduct, data privacy and security, and other related and similar subjects. Among other things, governmental regulations and enforcement actions restrict our operations at times and may adversely affect our financial condition, results of operations and cash flows by imposing limitations or other conditions on constructing or expanding facilities; collection and disposal pricing and volume; transportation of out-of-state waste and management and processing of certain waste streams.

Regulations affecting the siting, design and closure of landfills require us, at times, to undertake investigatory or remedial activities, curtail operations or close landfills temporarily or permanently. We have significant financial obligations relating to final capping, closure, post-closure and environmental remediation at our existing landfills and we establish accruals for these estimated costs. Expenditures could be accelerated or materially exceed our accruals due to earlier than expected closure of landfills; the types of waste collected and manner in which it is transported and disposed of, including actions taken in the past by companies we have acquired or third-party landfill operators; environmental regulatory changes; new information about waste types previously collected, or other emerging contaminants. Similar issues can also result in a significant increase in operating costs; for example, developments in recent years related to management of per- and polyfluoroalkyl substances ("PFAS") have increased our landfill operating costs. See Item 1. *Business – Regulation – Recent Developments and Focus Areas in Policy and Regulation – PFAS* for additional information. We may face increased exposure to testing, remediation and litigation costs as a result of new and emerging PFAS regulations and requirements.

Regulations establishing extended producer responsibility ("EPR") are being considered or implemented in many places around the world, including in certain states in the U.S. and provinces and territories in Canada. EPR regulations are designed to place either partial or total responsibility on producers of consumer-packaged goods and other products to fund the post-use life cycle of the products and packaging they create. At the same time, concerns over price and

[**Table of Contents**](#TOC)

affordability have led some jurisdictions to scale back previously enacted EPR requirements, and certain programs have faced lawsuits and potential constitutional review, creating uncertainty for long-term planning. For additional information, See Item 1. *Business – Regulation – Recent Developments and Focus Areas in Policy and Regulation – Extended Producer Responsibility*. A significant reduction in the waste, recycling and other streams we manage, including with respect to quality and volume, could have a material adverse effect on our financial condition, results of operations and cash flows. Conversely, changes in program requirements or deregulatory rulings in jurisdictions where we have adapted to meet customer demand could affect our operations, financial condition or results of operations.

We are also subject to additional laws and regulations in the U.S. and internationally concerning transportation, management and disposal or destruction of medical waste streams, including regulations that govern the definition, generation, segregation, handling, packaging, transportation, treatment, storage and disposal or destruction of medical waste and controlled substances waste, along with extensive recordkeeping and documentation requirements. Our secure information destruction services are subject to additional laws and regulations regarding proper handling and protection of personal and confidential information. Relaxation of enforcement, government shutdowns, or other changes in governmental regulation of medical waste and controlled substances waste and personal and confidential information could increase the number of competitors we face or reduce or delay the need for these services.

The current U.S. presidential administration has implemented substantial changes to foreign trade policy and is generally in favor of reducing regulation, including environmental regulation. The impact and timing of these shifts in regulatory policy impacting our industry and our Company remain uncertain, as many are subject to ongoing litigation and agency review. Reduction of regulation may have a favorable impact on our operating costs, but the extensive environmental regulation applicable to our industry is also a barrier to rapid entry that benefits our Company. It is likely that some policies adopted by this administration will benefit us and others will negatively affect us.

It is our policy to comply with all applicable anti-bribery laws, such as the U.S. Foreign Corrupt Practices Act ("FCPA"), and with applicable local laws of the foreign countries in which we operate, and we monitor our local partners' compliance with such laws as well. Our reputation may be adversely affected if we were reported to be associated with corrupt practices or if we or our local partners failed to comply with such laws. Additionally, violations of such laws could subject us to significant fines and penalties.

If we encounter regulatory compliance issues in the course of operating our business, we may experience adverse publicity, which may intensify if such noncompliance results in legal liability. Any legal liability or adverse publicity from such noncompliance may harm our reputation and result in difficulties in attracting new customers, or retaining existing customers, which would negatively impact our results of operations and financial condition.

***Our business is subject to operational and safety risks, including the risk of injury to employees and others.***

Providing environmental and waste management services, including constructing and operating landfills, transfer stations, processing facilities, recycling facilities and other disposal or destruction facilities, and landfill gas-to-energy facilities, involves risks such as truck accidents, equipment defects, malfunctions and failures, and improper use of dangerous equipment. Additionally, we closely monitor and manage landfills to minimize the risk of waste mass instability, releases of hazardous materials, and odors that are sometimes triggered by weather or natural disasters. There are also risks presented by the potential for subsurface heat reactions causing elevated landfill temperatures and increased production of leachate, landfill gas and odors, and we have proactively incurred increased costs to manage leachate in response to this risk. We build and operate natural gas fueling stations, some of which also serve the public or third parties. Operation of fueling stations and landfill gas collection and control systems, as well as operation of heavy machinery and management of flammable materials at our recycling facilities and transfer stations, involves additional risks of fire and explosion. The Healthcare Solutions business requires handling of medical waste and controlled substances waste and operates incineration facilities. Incidents such as truck accidents, damaged or leaking containers, improper storage of medical waste and controlled substances waste, placement of prohibited materials into the waste stream, or malfunctioning plant or incineration equipment could result in exposure to contaminated or infectious waste or other hazardous materials.

Any of these risks could potentially result in injury, illness or death of employees and others. These risks could also result in a need to shut down or reduce operation of facilities, increased operating costs and exposure to liability for pollution, public nuisance, and other environmental damage, and property damage or destruction. If we were to incur substantial liabilities in excess of any applicable insurance, our business, results of operations and financial condition could be adversely affected. Any such incidents could also tarnish our reputation and reduce the value of our brand. Additionally,

[**Table of Contents**](#TOC)

a major operational failure, even if suffered by a competitor, may bring enhanced scrutiny and regulation of our industry, with a corresponding increase in operating expense.

***We may be unable to obtain or maintain required permits for our operations or expand existing permitted capacity at our landfills, due to land scarcity, public opposition or otherwise, which can require us to identify disposal alternatives, resulting in decreased revenue and increased costs.***

Our ability to meet our financial and operating objectives depends in part on our ability to obtain and maintain the permits, authorizations, approvals, certificates, and other governmental permissions necessary to operate landfill sites, recycling facilities, compost facilities, processing facilities, landfill gas-to-energy facilities, incineration facilities and transfer stations in the various jurisdictions in which we operate. Changes in applicable laws and regulations could require us to obtain new permits or to change the way in which we operate our business. Even where permits are obtained, they may contain conditions or restrictions that limit our ability to operate efficiently. Permits to build, operate and expand solid waste management facilities, including landfills and transfer stations, have become more difficult and expensive to obtain and maintain. Permits often take years to obtain as a result of numerous hearings and compliance requirements with regard to zoning, environmental and other regulations. These permits are also often subject to resistance from citizen or other groups and other political pressures. Local communities and citizen groups, adjacent landowners or governmental agencies may oppose the issuance of a permit or approval we may need, allege violations of the permits under which we currently operate or laws or regulations to which we are subjected, or seek to impose liability on us for alleged environmental damage. Such actions could also impact our ability to do business by causing reputational harm. Our ability to receive permits is also impacted by land scarcity, particularly in densely populated areas. Diminishing disposal capacity, typically in proximity to major metropolitan areas, sometimes requires us to transport waste by rail or find alternative disposal solutions in affected areas, increasing our operating costs. Certain governmental bodies are in various stages of adopting or considering the adoption of requirements for environmental justice reviews as part of certain permitting decisions. These policies generally require permitting agencies to give heightened attention to a project's potential to disproportionately impact low-income and minority communities and to proactively plan for community engagement. Responding to permit challenges has, at times, increased our costs and extended the time associated with establishing new facilities and expanding existing facilities. Our failure to obtain the required permits and necessary capacity expansion to operate our business, including our landfills, could have a material adverse impact on our financial condition, results of operations and cash flows.

***If we are unable to attract, hire, develop and retain key team members and a high-quality workforce, and comply with applicable employment regulations, it could result in business and strategic disruption and increased costs, negatively impacting our results of operations.***

Our operations require us to attract, hire, develop and retain a high-quality workforce; this includes key individuals in leadership and specialty roles, as well as a very large number of skilled drivers, technicians and other front-line and back-office team members necessary to provide our environmental services. We experience significant competition to hire and retain certain front-line positions, such as commercial truck drivers. Additionally, the market for employees that serve on our digital team and support our investments in our technology-led automation and optimization strategy is highly competitive. We also compete to attract skilled business leaders, and our own key team members are sought after by our competitors and other companies. Labor shortages, as we have experienced in the past, could result in increased costs due to wage adjustments, overtime hours, training costs and inability to service customers. As an employer of over 60,000 individuals throughout the U.S. and Canada, as well as Western Europe and India, we are subject to numerous employment related regulations, including federal and state wage and hour laws and rapidly changing laws related to employment eligibility. If we are not able to attract, hire, develop and retain a high-quality workforce with the necessary skills and expertise, if we experience significant employee turnover, or if we fail to comply with applicable employment regulations, it can result in business and strategic disruption, increased costs, and loss of institutional knowledge, which could negatively impact our results of operations.

***Increases in our labor costs as a result of unions organizing, Multiemployer Pension Plan withdrawals, changes in regulations related to labor unions or increases in minimum wages, could adversely affect our future results.***

Labor unions continually attempt to organize our employees, and these efforts will likely continue in the future. Certain groups of our employees are currently represented by unions, and we have negotiated collective bargaining agreements with these unions. Additional groups of employees may seek union representation in the future, and, if successful, would enhance organized labor's leverage to obtain higher than expected wage and benefits costs and resist

[**Table of Contents**](#TOC)

the introduction of new technology and other initiatives, which can result in increased operating expenses and lower net income. If we are unable to negotiate acceptable collective bargaining agreements, our operating expenses could increase significantly as a result of work stoppages, including strikes. We are a participating employer in a number of trustee-managed multiemployer defined benefit pension plans ("Multiemployer Pension Plans") for employees who are covered by collective bargaining agreements. In the event of our withdrawal from a Multiemployer Pension Plan, we may incur significant expenses associated with our obligations for unfunded vested benefits at the time of the withdrawal that could have a material adverse effect on results of operations or cash flows.

Additionally, a large portion of our workforce are hourly personnel, and many of these individuals, particularly in our recycling business, are paid at rates related to federal and state minimum wages. Increases in minimum wage rates, or the enactment of new wage-related legislation, may significantly increase our labor costs. Any of these matters could adversely affect our financial condition, results of operations and cash flows.

***The seasonal nature of our business, severe weather events resulting from climate change and event driven projects cause our results to fluctuate, and prior performance may not be indicative of our future results.***

Our financial and operating results may fluctuate for many reasons. Our operating revenues and volumes typically experience seasonal increases in the summer months, that are reflected in second and third quarter revenues and results of operations. 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. Margins on weather-related and other event-driven projects may not be consistent with our ordinary course business. For these and other reasons, operating results in any period may not be indicative of operating results for any other period. Our stock price may be negatively impacted by interim variations in our results.

***We have made significant investments in an extensive natural gas truck fleet, which makes us partially dependent on the availability of natural gas and fueling infrastructure and vulnerable to natural gas prices, and requirements to transition away from our current vehicle fleet to electric powered vehicles could impair our investments and result in cost increases and significant additional capital investment.***

We operate a large fleet of natural gas vehicles, and we plan to continue to invest in these assets for our collection fleet. However, natural gas fueling infrastructure is not yet broadly available in the U.S. and Canada; as a result, we have constructed and operate natural gas fueling stations, some of which also serve the public or pre-approved third parties. It will remain necessary for us to invest capital in fueling infrastructure to power our natural gas fleet. Fluctuations in the price and supply of natural gas or diesel fuel could substantially increase our operating expenses; a reduction in the existing cost differential between natural gas and diesel fuel could materially reduce the benefits we anticipate from our investment in natural gas vehicles.

There is increasing pressure to reduce the use of fossil fuel in the heavy-duty truck industry, and some regulatory bodies are pursuing requirements for using alternative engine technology, such as electric powered vehicles, rather than natural gas or diesel vehicles. This is resulting in regulatory actions to advance the adoption of zero-emission vehicles and a shift away from tax incentives and grants for natural gas trucks and RNG infrastructure. See Item 1. *Business – Regulation – Investment in Natural Gas Vehicles and Infrastructure* for additional information. Regulation mandating an accelerated transition to electric powered vehicles would increase our cost to acquire vehicles needed to service our customers, and capital investment required to establish sufficient charging infrastructure could be significant. Additionally, the investments we have made in an industry-leading natural gas fleet and infrastructure could be impaired. Tax incentives and grants that advance the adoption of zero-emissions vehicles and lead to a shift away from natural gas trucks and RNG infrastructure would likely also negatively impact our investments in landfill gas-to-energy facilities.

***We may not be able to achieve our sustainability-related goals, including reduction of our greenhouse gas ("GHG") emissions, or achieve the results and benefits anticipated from our sustainability-related investments and initiatives within planned timelines or anticipated budget.***

We have set goals to reduce our GHG emissions and announced other sustainability-related goals and initiatives. We may not be able to meet such goals or implement such initiatives in the manner or on timelines contemplated due to

[**Table of Contents**](#TOC)

challenges including, but not limited to, unforeseen costs or delays, changes in how GHG emissions are calculated or otherwise reported, supply chain disruptions, regulatory impacts, integration of acquired assets or businesses, technology limitations or technical difficulties associated with achieving such goals. Changes to our business or asset base that were not contemplated when we set our sustainability-related goals could adversely impact our progress towards these goals and require us to adjust them. These changes could negatively impact public perception of our Company and stakeholders may view these changes unfavorably. Also, despite voluntarily announcing such sustainability goals, we may receive pressure from investors or other groups to adopt more aggressive sustainability-related goals that may not be technically, operationally, or financially feasible.

In addition, we have made significant investments in our Recycling Processing and Sales and Renewable Energy segments. Timing and achievement of the results and benefits anticipated from these investments may be impacted by the numerous risks and uncertainties including financial and operating performance; availability of technology and financing; compliance with regulations; inability to develop, obtain or scale necessary equipment; technology and innovations; challenges arising from the availability or cost of materials and infrastructure; difficulty obtaining regulatory approvals or permits; commodity price fluctuation and general economic conditions. (Also see Item 1A. *Risk Factors* — *Our revenues, earnings and cash flows fluctuate based on changes in commodity prices and demand and may fluctuate substantially without notice in the future* and *— Changes to federal and state renewable fuel policies could affect the financial performance of our Renewable Energy segment*). Favorable expectations regarding potential investment tax credits or other benefits stemming from the IRA and the OBBBA may not materialize or could fail to meet expectations. See Item 1. *Business – Regulation – Recent Developments and Focus Areas in Policy and Regulation – Tax Legislation* for additional information.

We have also forecasted or projected certain operational and financial information with respect to our sustainability investments and initiatives. For example, the amount of gas produced over time at landfills can vary depending on many factors, including weather and the composition of the inbound waste stream. Gas curves are inherently uncertain, and if we have less gas than predicted at a site where we have invested in RNG infrastructure, it may take longer to achieve our return on investment. Relatedly, the quality of the gathered gas is subject to the composition of the waste deposited at our landfills, and the prevalence of certain chemical compounds may adversely affect the usability of such gas and require further investment in the treatment and management of such compounds. Regulations requiring diversion of organic waste away from landfills could have the effect of decreasing the amount of landfill gas produced over time in our landfills.

***Focus on, and regulation of, sustainability performance and disclosure can result in increased costs, risk of noncompliance, damage to our reputation and related adverse effects.***

The nature, scope, and complexity of matters that our Company must assess, quantify and disclose are expanding due to current, proposed, and recently enacted governmental reporting requirements pertaining to sustainability and climate-related risks and other topics, such as water usage, waste production, labor, human capital, environmental justice, cybersecurity, privacy, and risk oversight. See Item 1. *Business – Regulation – Recent Developments and Focus Areas in Policy and Regulation – Climate and Sustainability* for more information. Methodology and timelines for mandatory reporting requirements may be inconsistent with requirements enacted by other governmental entities, including with respect to measuring emissions and requiring a determination of "materiality" that may differ from traditional disclosure requirements under U.S. federal securities laws.

Our industry faces challenges to implement these rapidly developing disclosure requirements, as well as the risk of enforcement actions by governmental and regulatory agencies for noncompliance. Significant expenditures and commitment of time by management, employees and consultants is involved in developing, implementing and overseeing policies, practices, additional disclosures and internal controls related to environmental and sustainability risk and performance. Public statements with respect to sustainability matters are subject to heightened scrutiny related to the risk of potential "greenwashing," *i.e.*, allegations of misleading information or false claims overstating potential sustainability benefits made by governmental authorities, non-governmental organizations and other private actors. An inability to implement such policies, practices, and internal controls and maintain compliance with laws and regulations, or a perception among stakeholders that our sustainability disclosures and goals are insufficient or our goals are unattainable, could harm our reputation and competitive position and negatively impact our stock price and business performance.

**External and Industry Risks**

***Market disruption, including labor shortages, external strikes, supply chain constraints and major external events, and macroeconomic pressures, including inflation, have recently had, and may in the future have, an adverse impact on our business and results of operations.***

Market disruption resulting from labor shortages, external labor disputes and strikes, supply chain and transportation constraints, major external events, including pandemic conditions, and macroeconomic pressures have recently had, and may in the future have, an adverse impact on our results and can create risk and uncertainty in financial outlook. Inflation can and has increased costs for the goods and services we purchase, particularly for labor, repair and maintenance, and subcontractor costs. Aspects of our business rely on third-party transportation providers, and such services have become more limited and expensive. Significant restrictions and tariffs on foreign trade have a negative impact on our recycling export business and our cross-border commerce, particularly with Canada, decrease paper mills' demand for recycled corrugated cardboard used in packaging and increase the cost of certain equipment and other materials used in our operations that we procure from outside the U.S., including our trucks and certain equipment used to implement our sustainability growth strategy. Geopolitical conflicts and the resulting international responses may also exacerbate market disruption, leading to volatility in commodity prices, impacts on the availability and cost of energy, increased cyberattacks, and vendor and supplier disruptions across the global supply chain. Major external events, like pandemics or widespread social restrictions, could also have an adverse impact on our volumes, costs and operations. The extent and duration of the impact of these challenges are subject to numerous external factors beyond our control. If such impacts are prolonged and substantial, they could have a material negative effect on our results of operations.

Accelerated and pronounced economic pressures, such as rising interest rates and inflationary cost pressures, have in the past and may in the future impact our cost structure and capital expenditures. Significant components of our operating expenses vary directly as we experience changes in revenue due to volume and inflation, and we may not be able to dynamically manage our cost structure in response to such changes. A significant portion of our revenue is tied to a price escalation index with a lookback provision, resulting in a timing lag in our ability to recover increased costs under those contracts during periods of rapid inflation. Separately, for many of our customers we provide services under multi-year contracts that can restrict our ability to increase prices and the timing of such increases. The inability to adequately increase prices to offset increased costs and inflationary pressures, or otherwise mitigate the impact of these conditions on our business, will increase our costs of doing business and reduce our margins.

***The environmental services industry is highly competitive, and if we cannot successfully compete in the marketplace, our business, financial condition and operating results may be materially adversely affected.***

We encounter intense competition from governmental, quasi-governmental and private sources in all aspects of our operations and when expanding to new lines of business or new markets. We principally compete with large national waste management companies, counties and municipalities that maintain their own waste collection and disposal or recycling operations and regional and local companies of varying sizes and financial resources. The industry also includes companies that specialize in certain discrete areas of waste management, operators of alternative disposal facilities, companies that seek to use parts of the waste stream as feedstock for renewable energy and other by-products, and waste brokers that rely upon haulers in local markets to address customer needs. In recent years, the industry has seen some additional consolidation, though the industry remains intensely competitive. Counties and municipalities may have financial competitive advantages because tax revenues are available to them and tax-exempt financing is more readily available to them. Also, such governmental units may attempt to impose flow control or other restrictions that would give them a competitive advantage. In addition, some of our competitors may have lower financial expectations, allowing them to reduce their prices to expand sales volume or to win competitively-bid contracts, including large national accounts and exclusive franchise arrangements with municipalities. When this happens, we may lose customers and be unable to execute our pricing strategy, resulting in a negative impact to our revenue growth from yield on base business.

***Our revenues, earnings and cash flows fluctuate based on changes in commodity prices and demand and may fluctuate substantially without notice in the future.***

Prices and demand for recyclables fluctuate and are particularly susceptible to volatility based on macroeconomic conditions and regulations. The fluctuations in the market prices or demand for these commodities can affect our operating income and cash flows negatively, as we experienced in 2025, or positively, as we experienced in 2024. The decline in market prices in 2025 for recyclable commodities resulted in a year-over-year decrease in revenue of $166 million, and

[**Table of Contents**](#TOC)

the increase in market prices in 2024 for recyclable commodities resulted in a year-over-year increase in revenue of $245 million.

Regulations affecting, and in some cases restricting, the international flow of certain recyclables have led, and could in the future lead, to a reduction in export activity for such recyclables, as well as higher quality requirements and higher processing costs. We have made significant investments in our recycling business to increase automation and reduce labor dependency and address increases in regulatory- and customer-driven quality requirements for commodities. These investments increase our exposure to commodity price fluctuations. Future regulation, tariffs, international trade policies or other initiatives, including regulations addressing climate change or GHG emissions, may impact supply and demand of material and availability of counterparties, or increase operating costs, which could impact the profitability of our recycling operations. If we do not effectively manage changes in demand and commodity prices for recyclable materials, or if we do not successfully execute our sustainability growth strategy, our investments in recycling infrastructure and technology may not yield the results anticipated.

Fluctuation in energy-related prices also affects our business, including recycling of plastics manufactured from petroleum products. Our Renewable Energy segment generates and sells credits referred to as RINs. RINs prices generally respond to regulations enacted by the EPA, as well as fluctuations in supply and demand, and have historically been very volatile. Additionally, significant variations in the price of biogas, electricity and other energy-related products that are marketed and sold by our landfill gas recovery operations can result in a corresponding impact to our revenue from yield from such operations. Recent expansion of our Renewable Energy segment may introduce additional risks and volatility to our financial performance.

***Increasing customer preference for alternatives to landfill disposal and bans on certain types of waste could reduce our landfill volumes and cause our revenues and operating results to decline.***

Our customers are increasingly diverting waste to alternatives to landfill disposal, such as recycling and composting, while also working to reduce the amount of waste they generate. In addition, many state and local governments mandate diversion, recycling and waste reduction at the source and prohibit the disposal of certain types of materials at landfills, such as recyclables (cardboard, bottles and cans), yard waste, food waste and electronics. Where organic waste is not banned from disposal in landfills, some large customers such as grocery stores and restaurants are choosing to divert their organic waste from landfills. Zero-waste goals (sending no waste to the landfill) have been set by many large North American and global companies and government agencies. This increased focus on minimizing climate impacts may require the Company to invest in higher-cost technologies. These developments reduce the volume of waste going to our landfills, which may affect the prices that we can charge for landfill disposal. Our landfills currently provide our highest income from operations margins. Reducing landfilled organic waste also reduces the amount of landfill gas produced from our landfills, adversely impacting our landfill gas-to-energy facilities. If we are not successful in expanding our service offerings, growing lines of businesses to service waste streams that do not go to landfills, and providing alternative services for customers that wish to reduce waste entirely, then our revenues and operating results may decline. Additionally, despite the development of new service offerings and lines of business, it is possible that our revenues and our income from operations margins could be negatively affected due to disposal alternatives.

With a heightened awareness of the global problems caused by plastic waste in the environment, and actual or perceived risks for human health, many governments have passed ordinances banning certain types of plastics from sale or use. The most common materials banned include plastic bags and straws, polystyrene plastic and some types of single use packaging. These bans have increased pressure by manufacturers on our recycling facilities to accept a broader array of materials in curbside recycling and composting programs to alleviate public pressures to ban the sale of those materials. However, there are currently no or limited viable end markets for recycling many of these materials, and inclusion of such materials in our recycling stream increases contamination and operating costs that can negatively affect the results of our recycling operations.

***General economic conditions and consumer trends can directly and adversely affect revenues for our services, our income from operations margins and our overall financial results.***

Our business is directly affected by changes in consumer trends and economic factors that are outside of our control, including consumer preferences and priorities, consumer confidence, inflation, interest rates and access to capital markets. A weak economy generally results in decreased consumer spending and decreases in volumes of waste generated, which negatively impacts the ability to grow through new business or service upgrades, and may result in customer turnover and reduction in customers' waste service needs. Consumer uncertainty and the loss of consumer confidence may also reduce

[**Table of Contents**](#TOC)

the number and variety of services requested by customers. Additionally, a weak market for consumer goods, or reduction in international trade due to tariffs or other factors, can significantly decrease demand by paper mills for recycled corrugated cardboard used in packaging, which can constrict availability of counterparties and negatively impact commodity prices and our operating income and cash flows. While sustainability remains a priority for many customers, we have observed a shift in prioritization by some companies with respect to sustainability objectives, including a decreased willingness to pay premium prices for recycled materials or enhanced sustainability solutions, which impacts demand for, and viability of, some of our offerings.

A decrease in waste volumes generated results in an increase in competitive pricing pressure; such economic conditions may also interfere with our ability to implement our pricing strategy. Many of our contracts have price adjustment provisions that are tied to an index such as the Consumer Price Index. Our costs may increase more than the increase, if any, in the Consumer Price Index, partially due to our relatively high fixed-cost structure. We may not be able to dynamically manage our cost structure in response to shifting volume levels and vendor costs, and our cost structure may not correlate with the Consumer Price Index or the waste industry. An economic recession or other economic weakness is likely to negatively impact our revenues and margins.

We provide service to a number of governmental entities, municipalities, and large national accounts. During periods of economic weakness, governmental entities and municipalities can suffer significant financial difficulties, due in part to reduced tax revenue and/or high-cost structures. During these periods, such entities, and our non-governmental customers, could be unable to pay amounts owed to us or renew contracts with us at previous or increased rates. In addition, the financial difficulties of municipalities could reduce investor demand for municipal bonds and cause a correlating increase in interest rates. As of December 31, 2025, we had $1.8 billion of tax-exempt bonds with term interest rate periods that expire within the next 12 months, which is prior to their scheduled maturities. If market dynamics resulted in repricing of our tax-exempt bonds at significantly higher interest rates, we would incur increased interest expenses that may negatively affect our operating results and cash flows.

***Reduction in volumes of medical waste, controlled substances wastes, and personal and confidential information, and changing conditions in the healthcare industry could adversely affect our financial results.***

Through our Healthcare Solutions segment, we provide compliance-based services that rely on the generation of medical waste, controlled substances waste and personal and confidential information by our customers. The volume of such material may be impacted by macroeconomic trends associated with manufacturing and industrial markets, healthcare market dynamics, and trends associated with an increase in work-from-home arrangements and electronic and digital record keeping. Long-term trends resulting from these factors could reduce the demand for these services.

In addition, in the U.S. and elsewhere, the healthcare industry is evolving to meet competing demands for increased healthcare coverage of a growing and aging population and economic pressures to reduce healthcare costs. As a result of these dynamics, hospital networks are consolidating physician practices into their networks, independent practices are consolidating, and healthcare providers are focused on cutting costs within their businesses. These changes and consolidation of the customer base increase the competitive nature of the healthcare waste industry and exert downward pricing pressure, which could adversely affect our financial results.

***Changes to applicable tax laws and regulation or interpretation thereof or the imposition of new or increased taxes may increase our tax liabilities and could adversely affect our operating results and cash flows***.

We are subject to various complex and evolving U.S. federal, state, local and non-U.S. tax laws. Existing tax laws, policies, statutes, rules, regulations or ordinances, including those related to any non-U.S. tax jurisdictions in which we operate, could be interpreted, changed, modified or applied adversely to us, in each case, possibly with retroactive effect. Any significant variance in our interpretation of current tax laws or a successful challenge of one or more of our tax positions by the U.S. Internal Revenue Service or other tax authorities could increase our future tax liabilities and adversely affect our operating results and cash flows.

***Shortages in diesel fuel supply or increases in diesel fuel prices will increase our operating expenses.***

The price and supply of diesel fuel can fluctuate significantly based on international, political and economic circumstances, as well as other factors outside our control, such as actions by oil and gas producers, regional production patterns, weather conditions and environmental concerns. We need diesel fuel to run a notable portion of our collection and transfer trucks and our equipment used in our landfill operations. Fuel supply shortages and price increases could substantially increase our operating expenses. Regardless of any offsetting surcharge programs, increased operating costs

[**Table of Contents**](#TOC)

due to higher diesel fuel prices will decrease our income from operations margins.

**Technology, Intellectual Property and Information Security Risks**

***If we are not able to develop new service offerings and protect intellectual property, or if a competitor develops or obtains exclusive rights to a breakthrough technology, our financial results may suffer.***

Our existing and proposed service offerings to customers require that we invest in, develop, license, and protect new technologies. Our Company is continuing our multi-year commitment to strategic investments in technology that automate and innovate our operations, improve the customer experience, provide alternatives to traditional disposal and maximize the resource value of waste. Research, development and implementation of enhanced technology often requires significant spending that may divert capital investment away from our traditional business operations. We may experience difficulties or delays in the research, development, production and/or marketing of new products and services or implementation of technologies in which we have invested or acquired, which may negatively impact our operating results and prevent us from recouping or realizing a return on these investments and acquisitions. Further, protecting our intellectual property rights and combating unlicensed copying and use of intellectual property is difficult and expensive, and an inability to obtain or protect new technologies could impact our services to customers and the development of new revenue sources. We rely on a combination of patents and trade secrets to protect our intellectual property, as well as confidentiality and non-disclosure agreements with employees, contractors, and other third parties. We cannot guarantee that these measures will fully prevent unauthorized access or use. Furthermore, there is no assurance that current or future applications will result in issued patents or, if issued, will provide adequate protection against competitors or other third parties. If a competitor or other third party develops or obtains exclusive rights to a "breakthrough technology" that provides a revolutionary change in our industry, or if we have inferior intellectual property to our competitors, our financial results may suffer.

We believe we have developed a reputation for high-quality service, reliability and social and environmental responsibility, and we believe our brand symbolizes these attributes. Intellectual property including the WM brand name, trademarks and logos are powerful sales and marketing tools, and we devote significant resources to promoting and protecting them.

***We are increasingly dependent on technology, and if our technology fails, our business would be adversely affected.***

Our Company, our customers, and the economy in general are increasingly dependent on continuous information technology systems and digital tools to conduct operations. This dependence spans nearly all areas of our business, from overseeing and controlling critical infrastructure to processing and securing proprietary and sensitive information. The information technology systems and networks that we, our customers, suppliers, and other third parties rely on can be vulnerable to disruptions from cyberattacks, power failures, telecommunications outages, major events like natural disasters, acts of war or terrorism, employee errors, and other unexpected or uncontrollable occurrences. Systems that increase our utilization of, and dependency on, third-party cloud computing services and digital platforms also increase various technology risks, including potential exposure to cyber incidents, loss of data, fraud, internal control challenges and other disruptions. Challenges in implementing new systems can affect our ability to comply with laws and regulations and realize projected cost savings or other benefits. Should our systems be compromised or cease to function effectively, we may face substantial costs to repair or replace them, as well as potential liability, loss of crucial data, reputational harm and interruptions to our services or operations.

***Inability to adapt to and manage the benefits and risks of artificial intelligence could expose us to liability or put us at a disadvantage.***

Artificial intelligence could disrupt certain aspects of our business and change use of technology in ways that are not yet known. Artificial intelligence technologies are subject to a variety of laws and compliance risk, including intellectual property, data protection and privacy, cybersecurity, consumer protection, competition, and equal opportunity laws, and are expected to be subject to increased regulation and new laws or new applications of existing laws. The use of artificial intelligence may also result in litigation, ethical concerns, and other legal and business risks. If we are not able to adapt and effectively incorporate potential advantages of artificial intelligence in our business, it may negatively impact our ability to compete. If we are not able to effectively govern the use and manage the risks of artificial intelligence, we may suffer harm to our results of operations and reputation.

[**Table of Contents**](#TOC)

***Significant cybersecurity incidents may negatively impact our business and our relationships with customers, vendors and employees and expose us to increased liability.***

Substantially all aspects of our business operations rely on digital technology. We use computers, mobile devices, social networking and other online platforms to connect with our employees, customers, vendors, as well as other individuals and third parties. These uses give rise to cybersecurity risks, including security breach, ransomware, espionage, system disruption, theft and/or inadvertent, accidental, unlawful, unauthorized access, loss, alteration, destruction and/or disclosure or release of information. Our business necessitates the processing, collection, use, storage and transmission of numerous classes of sensitive and/or confidential information and intellectual property, including individuals' personal information, private and sensitive employment-related personal data, and financial and strategic information about the Company and other businesses. In addition to our own safeguarding efforts, we also rely on third parties to process, collect and store sensitive data, including a Payment Card Industry compliant third-party to protect our customers' credit card information. We are regularly the target of attempted cyber intrusions, have experienced cyber intrusions, and anticipate continuing to be subject to such attempts as cyber intrusions become increasingly sophisticated and more difficult to predict and protect against. Technological advancements, including the progression of the capabilities of artificial intelligence, also increase the risk, likelihood and precision of cyber incidents. As such, we must commit substantial resources to continuously monitor and further enhance our networks and infrastructure to prevent, detect, and address the risk of unauthorized access, misuse, computer malware and other events. These protections and other systems designed to mitigate cybersecurity risks may not fully defend against an attack or future cybersecurity incident, which can be unpredictable in nature. Data security measures that our third-party service providers have implemented may not be effective against all current or future security threats. We also cannot guarantee that the systems, networks, equipment or software used by us or our third-party service providers have not been breached or otherwise compromised.

Although we believe that the probability of occurrence of a significant cybersecurity incident is less than likely, if such an incident were to occur, the impact on the Company could be substantial. The magnitude of future cyber intrusions that result in a theft, destruction, loss, misappropriation, or release of sensitive and/or confidential information (belonging to us or third parties) or intellectual property, or material interference with our information technology systems or the technology systems of third parties on which we rely cannot be predicted, such incidents could result in material business disruption, direct financial loss, remediation costs, reputational harm, brand damage, alleged violation of privacy laws, loss of customers, potential regulatory investigations and enforcement or private litigation liability and competitive disadvantage. To mitigate these risks, we maintain a cybersecurity insurance policy; however, due to policy terms, limits and exclusions, such insurance may not apply in all cases, and it may not be adequate to cover all liabilities incurred. Regulatory enforcement action concerning privacy infringement and security incidents is generally increasing, including significant fines recently imposed by U.K. and European regulators. Our Healthcare Solutions operations in Western Europe may subject us to short notification deadlines in international jurisdictions in the event of a significant cybersecurity incident that impacts us globally; it may not be possible for us to comply with such notification deadlines due to the time required to conduct investigations and assess the impact of such incident. Failure to comply with applicable laws and regulatory deadlines could attract enforcement action, penalties, litigation, investigations, proceedings, reputational harm and brand damage.

The Company is also expanding and improving its information technologies, resulting in a larger technological presence, utilization of cloud computing services, and corresponding exposure to cybersecurity risk. Certain new technologies, such as the use of autonomous vehicles, remote-controlled equipment, virtual reality, automation and artificial intelligence, present new and significant cybersecurity safety risks that must be analyzed and addressed before implementation. If we fail to assess and identify cybersecurity risks associated with acquisitions and new initiatives, we may become increasingly vulnerable to such risks.

***Increasing regulatory focus on privacy and data protection issues and expanding laws could negatively impact our business, subject us to criticism and expose us to increased liability.***

The legislative and regulatory framework for security, privacy and data protection issues worldwide is rapidly evolving and is likely to remain uncertain for the foreseeable future. We collect, use, share, retain, delete and otherwise process certain personal data and other sensitive information in connection with our operations and are subject to increasingly demanding U.S. and international laws and regulations related to data protection and privacy and the protection of confidential information. These laws and regulations are inconsistent across jurisdictions and are subject to evolving interpretations. Government officials, regulators, customers, privacy advocates and class action attorneys are increasingly scrutinizing how companies collect, process, use, store, share, transmit and destroy personal data. The

[**Table of Contents**](#TOC)

continued emphasis on personal privacy and information security may result in customers requesting that we implement additional safeguards or controls. One recent focus area involves the use of phone, text and email information for sales, marketing and other business purposes. We must continually monitor the development and adoption of, and commit substantial time and resources to comply with, new and emerging laws and regulations and/or expanded or novel interpretations of existing laws. Additionally, customers and regulators may seek to hold us responsible for the actions of third parties we work with, such as sub-processors, vendors or developers.

Increased state, federal and international laws and regulations related to cybersecurity protections and disclosures will require additional resources for compliance, and any inability, or perceived inability, to adequately address new requirements could subject us to regulatory enforcement, private litigation, public criticism, disrupt our operations, cause us to lose customers, result in additional costs and legal liability, damage our reputation, and otherwise harm our business.

Any inability, or perceived inability, to adequately address privacy and data protection concerns, even if unfounded, or to comply with laws, regulations, policies, industry standards, contractual obligations, or other legal obligations, including through acquired companies or third parties, could subject us to regulatory enforcement, private litigation, public criticism, business disruption, loss of customers, additional costs and legal liability, reputational damage and other harm.

**Legal, Regulatory and Compliance Risks**

***Our operations are subject to environmental, health and safety laws and regulations, as well as contractual obligations that may result in significant liabilities.***

There is risk of incurring significant environmental liabilities in the use, treatment, storage, transfer, processing and disposal or destruction of waste materials. Under applicable environmental laws and regulations, we could be liable if it is alleged that our operations cause environmental damage to our properties or to the property of other landowners, particularly as a result of the contamination of air, drinking water or soil. Under current law, we could also be held liable for damage caused by conditions that existed before we acquired the assets or operations involved and for conditions resulting from waste types or compounds previously considered non-hazardous but later determined to present possible threat to public health or the environment. The risks of successor liability and emerging contaminants are of particular concern as we execute our growth strategy, partially through acquisitions, because we may be unsuccessful in identifying and assessing potential liabilities during our due diligence investigations. Further, the counterparties in such transactions may be unable to perform their indemnification obligations owed to us. Any substantial liability for environmental damage could have a material adverse effect on our financial condition, results of operations and cash flows.

In the ordinary course of our business, we have in the past, we are currently, and we may in the future, become involved in legal and administrative proceedings relating to land use and environmental laws and regulations. These include proceedings in which governmental entities, private groups or individuals seek to impose liability on us for alleged environmental damage, violation of statutes, failure to meet contractual remediation conditions or desire to revoke or deny permits required for our operations. We generally seek to work with the authorities or other persons involved in these proceedings to resolve any issues raised. If we are not successful, the adverse outcome of one or more of these proceedings could result in, among other things, material increases in our costs or liabilities as well as material charges for asset impairments.

***Changes to federal and state renewable fuel policies could affect the financial performance of our Renewable Energy segment.***

The primary drivers of value for renewable fuel produced at our landfills are tax policies, such as the federal tax credits for investments in RNG production under the IRA and OBBBA, and federal and state incentive programs, such as the federal RFS program, the California Low Carbon Fuel Standard and similar state programs that promote the production and use of renewable transportation fuels, which are all subject to change. At the federal level, oil refiners and importers are required through the RFS program to blend specified volumes of renewable transportation fuels with gasoline or buy RINs from renewable fuel producers. The Company has made significant investments in facilities that capture and process landfill gas into RNG so that we can participate in the RFS program. RINs prices generally respond to regulations enacted by the EPA, as well as fluctuations in supply and demand. The value of the RINs is set through a market established by the RFS program, which market has historically been volatile. While the previous rules under the RFS program reflected the outsized role of biogas under the program and delivered reforms benefiting the solid waste sector, the current administration has retroactively lowered 2024 blending volumes, proposed reductions for 2025, set low targets for 2026–2027 and begun to grant small refinery exemptions from RFS program requirements. See Item 1. *Business – Regulation –* 

[**Table of Contents**](#TOC)

*Recent Developments and Focus Areas in Policy and Regulation – Renewable Energy* for additional information. Changes and volatility in the RINs market, or changes in the structure of the RFS program or other clean fuel standard programs, can and has impacted the financial performance of our facilities. Further changes could impact future growth investments in our Renewable Energy segment.

***The impact of climate change, and the adoption of climate change legislation or regulations restricting emissions of GHGs, could increase our costs to operate.***

We continue to assess the physical risks, such as sea-level rise, catastrophic storms and other extreme weather conditions and long-term shifts in climate patterns, and transition risks, such as regulatory, market, policy, and technology changes, to our operations from the effects of climate change. These risks are expected to be unpredictable and widespread. Damage to our facilities or disruption of service caused by more frequent or more severe storms associated with climate extremes could negatively impact operating results. We have also identified risk to our assets and our employees associated with drought or water scarcity, flooding, extreme heat and rain events, and fire conditions associated with climate change. For example, wildfires influenced by climate change can damage landfill infrastructure such as gas collection systems, and extreme rain events and flooding in low-lying areas enhanced by sea level rise can result in greater maintenance expenses at our facilities, service disruption, erosion of the protective vegetative caps on our landfills and increased volumes of leachate to manage. We have incurred and will incur costs to develop and implement protocols to address these conditions, but these protocols may not be effective in offsetting these risks. Additionally, the actions of others in response to climate change effects, such as rolling power blackouts, can result in service disruptions and increase our costs to operate.

Landfill operations emit methane, identified as a GHG. Existing technology presents challenges to quantify landfill emissions precisely. Ongoing review by government agencies of emerging methane measurement technologies and related regulatory developments could result in changes to how we have historically reported GHG emissions and may result in increases in such emissions reported for our operations. Such regulatory developments could also result in increased compliance costs and adversely affect our operations. See Item 1. *Business – Regulation – Recent Developments and Focus Areas in Policy and Regulation – Climate and Sustainability* for additional information.

Meanwhile, a number of legislative and regulatory efforts at the state, provincial, regional and federal levels and internationally aim to cap and/or curtail the emission of GHGs to ameliorate the effect of climate change, and otherwise to promote adaptation to climate change, support the transition to a low-carbon economy, and require disclosure of climate-related matters. We continue to monitor these efforts and the potential impacts to our operations. Should comprehensive federal climate change legislation be enacted, we expect it could impose operational and compliance costs that might not be offset by the revenue increases associated with our lower-carbon service options. Climate change laws and regulations could also result in increased operational costs or disruption to the business of our customers, potentially impacting our operations and financial condition. We could experience damage to our reputation and brand, including as a result of a failure or perceived failure to respond responsibly and effectively to changes in legal and regulatory measures adopted to address climate change.

***Failure to maintain an effective system of internal control over financial reporting, due to technology issues, difficulties integrating Stericycle's operations and systems, or otherwise, could adversely affect our ability to provide accurate and timely financial statements, which may harm our business and reputation.***

It is critical that we maintain an effective system of internal control over financial reporting. Establishing, testing and maintaining an effective system of internal control over financial reporting requires significant resources and time commitments on the part of our management and our finance staff, and the time and expenditures needed may exceed our expectations. If we encounter issues with technology systems, including issues related to Stericycle's ERP system or difficulties integrating Stericycle's operations and systems into our system of internal control over financial reporting, and if we are unable to correct any issues encountered in a timely manner, our ability to record, process, summarize, and report financial data may be adversely affected, which may impact the accuracy, quality and completeness of our financial statements. Such failure could materially and adversely impact our business and subject us to potential investigations, liability, and penalties. Additionally, if we are unable to conclude that our internal control over financial reporting is effective in any future period (or if our auditors are unable to express an opinion on the effectiveness of our internal controls or conclude that our internal controls are ineffective), we could lose investor confidence and suffer an adverse effect on our stock price.

[**Table of Contents**](#TOC)

***Currently pending or future litigation or governmental proceedings could result in material adverse consequences, including judgments or settlements.***

As a large company with extensive operations, we are subject to various proceedings, lawsuits, disputes and claims arising in the ordinary course of our business, including governmental proceedings. 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 materials and odors;

● sales and marketing practices, customer service agreements, prices and fees; and

● federal and state wage and hour and other laws.

The timing of the final resolutions to these types of matters is often uncertain. Additionally, the possible outcomes or resolutions to these matters could include adverse judgments or settlements, either of which could require substantial payments, adversely affecting our liquidity.

At the time of our acquisition of Stericycle, it was, and had been, involved in certain government investigations, enforcement proceedings, lawsuits and other disputes alleging noncompliance with applicable regulations, including alleged noncompliance with the Controlled Substances Act and other statutes involving its now-divested Domestic Environmental Solutions business, which collected, transported and destroyed controlled substances from retail customers. Resolution of these matters may result in adverse consequences, including permit revocations or denials and civil, criminal and administrative penalties.

**Financial Risks**

***Our capital requirements and our business strategy could increase our expenses, cause us to change our growth and development plans, or result in an inability to maintain our desired credit profile.***

If economic conditions or other risks and uncertainties cause a significant reduction in our cash flows from operations, we may reduce or suspend capital expenditures, growth and acquisition activity, implementation of our business strategy, dividend declarations or share repurchases. We may choose to incur indebtedness to pay for these activities, although our access to capital markets is not assured, and we may not be able to incur indebtedness at a cost that is consistent with current borrowing rates. We also may need to incur indebtedness to refinance scheduled debt maturities, and it is possible that the cost of financing could increase significantly, thereby increasing our expenses and decreasing our net income. Further, our ability to execute our financial strategy, manage interest rate exposure and incur indebtedness is somewhat dependent upon our ability to maintain investment grade credit ratings on our senior debt. The credit rating process is contingent upon our credit profile and several other factors, many of which are beyond our control, including methodologies established and interpreted by third-party rating agencies. An important factor in our credit ratings is our leverage. If we do not achieve our projected reduction in leverage following our acquisition of Stericycle, it could negatively impact our credit ratings. If we were unable to maintain our investment grade credit ratings in the future, our interest expense would increase and our ability to obtain financing on favorable terms could be adversely affected. We have $2.9 billion of debt as of December 31, 2025 that is exposed to changes in market interest rates within the next 12 months, associated with our commercial paper borrowings and tax-exempt bonds. If interest rates increase, our interest expense would also increase, lowering our net income and decreasing our cash flow.

We may use our $3.5 billion long-term U.S. and Canadian revolving credit facility ("$3.5 billion revolving credit facility") to meet our cash needs, to the extent available, until maturity in May 2029. As of December 31, 2025, we had no outstanding borrowings under this facility. We had $1.1 billion of outstanding borrowings (net of related discount on issuance) under our commercial paper program and $227 million of letters of credit issued, both supported by this facility, leaving unused and available credit capacity of $2.2 billion as of December 31, 2025. In the event of a default under our $3.5 billion revolving credit facility we could be required to immediately repay all outstanding borrowings and make cash deposits as collateral for all obligations the facility supports, which we may not be able to do. Additionally, any such default could cause a default under many of our other credit agreements and debt instruments. Without waivers from lenders party to those agreements, any such default would have a material adverse effect on our ability to operate.

***Increases in the costs of obtaining adequate financial assurance, or the inadequacy of our insurance coverages, could negatively impact our liquidity and increase our liabilities.***

The amount of insurance we are required to maintain for environmental liability is governed by statutory requirements.

[**Table of Contents**](#TOC)

We also carry a broad range of other insurance coverages that are customary for a company our size. To the extent our obligations for claims are more than we estimated, our insurance coverage is inadequate to cover our obligations, or our insurers are unable to meet their obligations, the requirement that we pay such obligations could have a material adverse effect on our financial results.

In addition, to fulfill our financial assurance obligations with respect to variable-rate tax-exempt debt, and final capping, closure, post-closure and environmental remediation obligations, we generally obtain letters of credit or surety bonds, rely on insurance, including captive insurance, fund trust and escrow accounts or rely upon WMI financial guarantees. Our financial position, which can be negatively affected by asset impairments, our credit profile and general economic factors, may increase the cost of our current financial assurance instruments, and changes in regulations may impose stricter requirements on the types of financial assurance that will be accepted. In the event we are unable to obtain sufficient surety bonding, letters of credit or third-party insurance coverage at reasonable cost, or one or more states cease to view captive insurance as adequate coverage, we would need to rely on other forms of financial assurance. It is possible that we could be required to deposit cash to collateralize certain obligations, which could negatively impact our liquidity.

***We may record material charges against our earnings due to impairments to our assets.***

Events that have in the past and may in the future lead to an impairment include, but are not limited to, shutting down or divesting an underperforming or non-strategic asset or operation, abandoning a development project, project cost overruns or the denial of an expansion permit. Additionally, declining waste volumes and development of, and customer preference for, alternatives to traditional waste disposal could warrant asset impairments. If we determine an asset or expansion project is impaired, we will charge against earnings any unamortized capitalized expenditures and advances relating to such asset or project reduced by any portion of the capitalized costs that we estimate will be recoverable, through sale or otherwise. We also carry a significant amount of goodwill on our Consolidated Balance Sheets, which is required to be assessed for impairment annually, and more frequently in the case of certain triggering events. We have in the past and may in the future be required to incur charges against earnings if such impairment tests indicate that the fair value of a reporting unit is below its carrying amount. Any such charges could have a material adverse effect on our results of operations.

#### Item 1C. Cybersecurity.
**Strategy, Governance and Risk Management**

Our Technology Risk Program is designed to proactively identify, monitor, and mitigate technology-related risks across our digital operations and assess cybersecurity risks related to third-party vendors and suppliers. Our Cybersecurity Program and our Technology Risk Program are led by our Chief Information Security Officer ("CISO"), a Certified Information Systems Security Professional with two decades of cybersecurity leadership. The CISO and his team are responsible for leading enterprise-wide cybersecurity strategy, policy, standards, architecture and processes. The Technology Risk Oversight Committee chaired by our CISO, with members representing leadership throughout our Company, provides oversight and guidance to technology risks, including cybersecurity, and our policies and procedures related to our development, deployment and monitoring of artificial intelligence.

Our Company's Cybersecurity Program is designed to align with the National Institute of Standards and Technology ("NIST") Cybersecurity Framework and leading industry practices, and our Cybersecurity Program is integrated into our Company's Enterprise Risk Management framework. Internal and external experts regularly evaluate our Cybersecurity Program, and the results of those reviews are reported to senior management and our Company's Board of Directors. Our Incident Response Committee, which is comprised of leaders in the areas of information security, digital, legal, finance, privacy, compliance and ethics, corporate security and communications, is responsible for leading our Company's response to cyber incidents. Our Cybersecurity Incident Response Plan outlines the processes by which management is informed about and monitors detection and mediation of cyber incidents. We actively engage with key vendors, industry participants, and intelligence and law enforcement communities as part of our continuing efforts to evaluate and enhance the effectiveness of our information security policies and procedures. We have a Data Protection Office that works closely with, and assists, our enterprise Privacy Program, overseen by the Chief Privacy Officer, along with advisory support from appointed Data Protection Officers in Europe and Quebec.

While we have experienced cybersecurity threats and breaches targeting our information and operations technology systems and networks and those of our third-party providers, including within the last three years, these incidents have not had a material impact on our Company, including our business strategy, results of operations or financial condition. Risks from cybersecurity threats, including previous cybersecurity incidents encountered by the Company and known incidents encountered by third parties with a connection to the Company, are also not currently viewed as reasonably likely to materially impact our Company, including our business strategy, results of operations or financial condition. We are regularly the target of attempted cyber intrusions, have experienced cyber intrusions, and we anticipate continuing to be subject to such attempts as cyber intrusions become increasingly sophisticated and more difficult to predict and protect against. Geopolitical conflicts and developments and technological advancements, including the progression of the capabilities of artificial intelligence, also increase the risk, likelihood and precision of cyber incidents.

As such, we must commit substantial resources to continuously monitor and further develop our networks and infrastructure to prevent, detect, and address the risk of unauthorized access, misuse, computer malware and other events. Although we have implemented and maintain commercially reasonable security measures, safeguards, policies and procedures, including to protect against and identify potential threats, these protections and other systems designed to mitigate cybersecurity risks may not fully defend against an attack or future cybersecurity incident, which can be unpredictable in nature. Although we believe that the probability of occurrence of a significant cybersecurity incident is less than likely, if such an incident were to occur, the impact on the Company could be substantial. See Item 1A. *Risk Factors* — *Significant cybersecurity incidents may negatively impact our business and our relationships with customers, vendors and employees and expose us to increased liability* for additional discussion.

[**Table of Contents**](#TOC)

**Board Oversight**

Management has primary responsibility for risk management within our Company. The Company's Board of Directors, with the support of its committees, oversees risk management to ensure that the processes designed, implemented and maintained by our executives are functioning as intended and adapted when necessary to respond to changes in our Company's strategy as well as emerging risks. The Audit Committee of the Company's Board of Directors has responsibility for oversight of information and cybersecurity risks and assessment of cyber threats and defenses. The Audit Committee receives reports on these matters from our most senior executives in the digital organization, including our Chief Information Officer and CISO, and the Company's executive officers, at least twice a year. Topics historically covered in such reports, and for which our Board exercises oversight, include third-party evaluation of our technology infrastructure and information security against the NIST cybersecurity framework; management of emerging cyber threats such as merger and acquisition activity; use and governance of artificial intelligence, including oversight of our artificial intelligence policies and procedures; risk mitigation through the Company's enterprise-wide cybersecurity training, including our Board of Directors, conducted at least annually; regular simulated phishing tests and third-party penetration testing; review of the Company's cyber incident insurance coverage and external cyber incident resources; review of the Company's Cybersecurity Incident Response Plan; review of readouts from cyber incident table top exercises and consideration of applicable laws and regulations, including those related to privacy. The Company's Cybersecurity Incident Response Plan includes a section on Board escalation that specifies the process for notification of the Chair of the Audit Committee and the Chair of the Board of the Directors upon certain triggering events, and that group then determines the appropriate form and frequency of communication with the full Audit Committee or Board of Directors, depending on the unique characteristics of the incident.

#### Item 2. Properties.
Our principal executive offices are in Houston, Texas where we lease approximately 285,000 square feet under a lease expiring in 2035. We also have administrative offices in Arizona, Connecticut, Illinois, India and parts of Western Europe. We own or lease real property in most locations where we have operations or administrative functions. We have operations (i) in all 50 states; (ii) in the District of Columbia; (iii) parts of Canada and (iv) parts of Western Europe.

Our principal property and equipment consist of land (primarily landfills and other disposal facilities, transfer stations and bases for collection operations), buildings, vehicles and equipment. We believe that our operating properties, vehicles and equipment are adequately maintained and sufficient for our current operations. However, we expect to continue to make investments in additional property and equipment for expansion, for the replacement of aging assets and investment in assets that support our strategy of continuous improvement through efficiency and innovation. In addition, we continue to make progress on our investments to expand our Recycling Processing and Sales and Renewable Energy segments. For more information, see Item 7. *Management's Discussion and Analysis of Financial Condition and Results of Operations* included within this report.

The Company repurchases shares of its common stock as part of capital allocation programs authorized by our Board of Directors. Share repurchases are a part of our long-term strategy and incorporated into our overall capital allocation plan to enhance our Company's performance, in conjunction with our other uses of capital, and to return value to stockholders in a tax-efficient manner. There were no common stock repurchases during 2025. We announced in December 2025 that our Board of Directors has authorized up to $3.0 billion in future share repurchases, exclusive of fees, commissions and taxes. This new authorization supersedes and replaces remaining authority under the prior Board of Directors' authorization for share repurchases announced in December 2023. The amount of future share repurchases executed under our Board of Directors' authorization is determined in management's discretion, based on various factors, including our leverage level, net earnings, financial condition and cash required for future business plans, growth and acquisitions.

Additionally, in December 2025, we announced that our Board of Directors expects to increase the quarterly dividend from $0.825 to $0.945 per share for dividends declared in 2026. However, all future dividend declarations are at the discretion of the Board of Directors and depend on various factors, including our leverage level, net earnings, financial condition, cash required for future business plans, growth and acquisitions and other factors the Board of Directors may deem relevant.

#### Overview
We are North America's leading provider of comprehensive environmental solutions, primarily 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. We own or operate the largest network of landfills throughout the U.S. and Canada. In order to make disposal more practical for larger urban markets, where the distance to landfills is typically farther, we manage transfer stations that consolidate, compact and transport waste efficiently and economically. Our solid waste business is operated and managed locally by our subsidiaries that focus on distinct geographic areas and provide collection, transfer, disposal, recycling and resource recovery services. Through our Waste Management Renewable Energy ("Renewable Energy") segment, 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 ("RNG"), which is a significant source of fuel that we allocate to our natural gas fleet. Following our 2024 acquisition of Stericycle, Inc. ("Stericycle"), our Healthcare Solutions segment provides regulated waste and compliance services ("RWCS") and secure information destruction ("SID") services in the U.S., Canada and Western Europe that protect people and brands, promote health and well-being and safeguard the environment. Additionally, through our Recycling Processing and Sales segment, we are a leading recycler in the U.S. and Canada, handling materials that include paper, cardboard, glass, plastic and metal.

Our senior management evaluates, oversees and manages the financial performance of our business through five reportable segments, referred to as (i) Collection and Disposal - East Tier ("East Tier"); (ii) Collection and Disposal - West Tier ("West Tier"); (iii) Recycling Processing and Sales; (iv) Renewable Energy and (v) Healthcare Solutions. Our East and West Tiers, along with certain ancillary services ("Other Ancillary") that are not managed through our Tier segments but that support our collection and disposal operations, form our "Collection and Disposal" businesses. We also provide additional services not managed through our five reportable segments, which are presented as Corporate and Other.

***Stericycle Acquisition***

On November 4, 2024, we completed our acquisition of all outstanding shares of Stericycle for $62.00 per share in cash, pursuant to an Agreement and Plan of Merger dated June 3, 2024. Total enterprise value of the acquisition was $7.2 billion (net of cash acquired) when including the assumption of $0.5 billion of debt and the repayment of approximately $0.8 billion of net debt. The acquisition expanded our offerings in the U.S., Canada and parts of Western Europe. The post-closing operating results of Stericycle have been included in our Consolidated Financial Statements within our Healthcare Solutions segment.

[**Table of Contents**](#TOC)

For the year ended December 31, 2025, we incurred acquisition and integration related costs of $120 million, comprised of $89 million of selling, general and administrative costs and $31 million of restructuring costs. For the year ended December 31, 2024, we incurred acquisition and integration related costs of $160 million, which were primarily classified as selling, general and administrative expenses.Refer to Note 19 for more information on the performance of our Healthcare Solutions segment.

***Collection and Disposal***

Our Collection and Disposal businesses provide integrated environmental services, including collection, transfer and disposal. We evaluate our Collection and Disposal businesses primarily through two geographic segments, East Tier and West Tier. 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, Southern and Central U.S., including the upper Midwest region, and British Columbia, Canada. Additionally, we provide Other Ancillary services that are not managed through the Tier segments but that support our collection and disposal operations. Other Ancillary includes specialized services performed for customers that have differentiated needs. These specialized services are targeted at large industrial customers managed through our Sustainability and Environmental Solutions ("SES") business or geographically dispersed customers managed through our Strategic Business Solutions ("WMSBS") business. Also included within Other Ancillary are the results of non-operating entities that provide financial assurance and self-insurance support for our business, net of intercompany activity.

Our Collection and Disposal businesses' operating revenues are primarily generated from fees charged for our collection, transfer and disposal. Revenues from our collection operations are influenced by factors such as collection frequency, type of collection equipment furnished, type and volume or weight of the waste collected, distance to the disposal facility or recycling facility and our disposal costs. Revenues from our landfill operations consist of tipping fees, which are generally based on the type and weight or volume of waste deposited, considering our cost of loading, transporting and disposing of the solid waste at a disposal site. Fees charged at transfer stations are generally based on the weight or volume of waste deposited, considering our cost of loading, transporting and disposing of the solid waste at a disposal site. The fees we charge for our services generally include applicable fees, such as our energy surcharge, which are intended to pass through to customers for direct and indirect costs incurred.

Included within our Collection and Disposal businesses are landfills having (i) 19 third-party power generating facilities converting our landfill gas to fuel electricity generators; (ii) 17 third-party RNG facilities processing landfill gas to be sold to natural gas suppliers and (iii) nine third-party projects delivering our landfill gas by pipeline to industrial customers as a direct substitute for fossil fuels in industrial processes. In return for providing our landfill gas, we receive royalties from each facility, including the benefit of a 15% royalty from our Renewable Energy segment based on net operating revenue generated through the sale of RNG, renewable identification numbers ("RINs"), electricity and capacity, Renewable Energy Credits ("RECs") and related environmental attributes from the 86 landfill beneficial use renewable energy projects owned by Renewable Energy on our active landfills, which is eliminated in consolidation.

***Recycling Processing and Sales***

Our Recycling Processing and Sales segment includes the processing and sales of materials collected from residential, commercial and industrial customers. The materials are delivered to and processed at one of our many recycling facilities. Through our brokerage business, we also manage the marketing of recycling commodities that are processed in our facilities and by third parties by maintaining comprehensive service centers that continuously analyze market prices, logistics, market demands and product quality.

Recycling Processing and Sales revenues generally consist of tipping fees and the sale of recycling commodities to and/or on behalf of third parties. Our Recycling Processing and Sales segment excludes the collection of recycled materials from our residential, commercial, and industrial customers which is included within our Collection and Disposal businesses.

***Renewable Energy***

Our Renewable Energy segment develops, operates and promotes projects for the beneficial use of landfill gas. Landfill gas is produced naturally as waste decomposes in a landfill. The methane component of the landfill gas is a readily available, renewable energy source that can be gathered and used beneficially as an alternative to fossil fuel. Renewable Energy converts landfill gas into several sources of renewable energy which include RNG, electricity and capacity, heat and/or steam. Renewable Energy also generates (i) RINs under the Renewable Fuel Standard ("RFS") program; (ii) other credits under a variety of state programs associated with the use of RNG in our compressed natural gas fleet and (iii) RECs associated with the production of electricity. The RINs, RECs, and other credits are sold to counterparties who are obligated under the regulatory programs and have a responsibility to procure RINs, RECs, and other credits proportionate to their fossil fuel production and imports. RINs and RECs prices generally fluctuate in response to regulations enacted by the Environmental Protection Agency ("EPA") or other regulatory bodies, as well as changes in supply and demand.

As of December 31, 2025, we had 103 landfill gas beneficial use projects producing commercial quantities of methane gas at owned or operated landfills. For 62 of these projects, the processed gas is used to fuel electricity generators. The electricity is then sold to public utilities, municipal utilities or power cooperatives. For 24 of these projects, the gas is used at the landfill or delivered by pipeline to industrial customers as a direct substitute for fossil fuels in industrial processes. For 17 of these projects, the landfill gas is processed to pipeline quality RNG and then sold to natural gas suppliers. Additionally, three projects are on third-party landfills. The revenues from these facilities are primarily generated through (i) the sale of captured and converted landfill methane gas; (ii) the sale of RINs under the RFS program implemented by the EPA; (iii) sale of Low Carbon Fuel credits designed to stimulate the use of low-carbon fuels and (iv) the sale of energy (electricity and capacity) and associated RECs. Renewable Energy is charged a 15% royalty on net operating revenue from these facilities residing on our active and closed landfills from our Collection and Disposal and Corporate and Other businesses, which is eliminated in consolidation. Additionally, Renewable Energy operates and maintains six third-party landfill beneficial gas use projects in return for service revenue. Our Collection and Disposal and Corporate and Other businesses benefit from these projects as well as 54 additional third-party landfill beneficial gas use projects in the form of royalties.

***Healthcare Solutions***

Our Healthcare Solutions segment includes (i) RWCS which provide compliance programs and collection, processing, and disposal of regulated and specialized waste, including medical, pharmaceutical and hazardous waste and (ii) SID services, which provide for the collection of personal and confidential information for secure destruction and recycling of sorted office paper. While the Healthcare Solutions businesses manage large volumes of waste and other materials, the average volume per customer site is relatively small.

Our customers typically enter into a contract for the provision of services on a scheduled basis, including weekly, monthly or on an as-needed basis over the contract term. Under the contract terms, the Healthcare Solutions businesses receive fees based on a monthly, quarterly or annual rate and/or fees based on contractual rates depending upon measures including the type and volume or weight of waste. Operating revenues are invoiced based on the terms of the underlying contract either on a regular basis, or as services are performed and are generally due within a short period of time after invoicing based upon normal terms and conditions for our business type and the geography of the services performed.

As of December 31, 2025, our Healthcare Solutions segment operates out of approximately 307 leased and owned facilities worldwide with 51 autoclaves or other alternative medical waste treatment facilities, 17 medical waste incinerator facilities, 99 SID processing facilities and 140 transfer stations.

***Corporate and Other***

We also provide additional services that are not managed through our operating segments, which are presented in this report as Corporate and Other. This includes the activities of our corporate office, including costs associated with our long-term incentive program, expanded service offerings and solutions (such as our investments in businesses and technologies that are designed to offer services and solutions ancillary or supplementary to our current operations) as well as our closed sites. Also included within our Corporate and Other businesses closed sites are (i) five third-party power

[**Table of Contents**](#TOC)

generating facilities converting our landfill gas to fuel electricity generators; (ii) two third-party projects delivering our landfill gas by pipeline to industrial customers as a direct substitute for fossil fuels in industrial processes and (iii) two third-party RNG facilities processing landfill gas to be sold to natural gas suppliers in return for a royalty. Additionally, Corporate and Other benefits from a 15% royalty from our Renewable Energy segment based on net operating revenue generated through the sale of RNG, RINs, electricity and capacity, RECs and related environmental attributes from the 17 landfill beneficial use renewable energy projects owned by Renewable Energy on our closed sites, which is eliminated in consolidation.

***Business Environment***

The waste industry is a comparatively mature and stable industry. However, customers increasingly expect more of their waste materials to be recovered and those waste streams are becoming more complex. In addition, many state and local governments mandate diversion, recycling and waste reduction at the source and prohibit the disposal of certain types of waste at landfills. We monitor these developments to adapt our service offerings. As companies, individuals and communities look for ways to be more sustainable, we promote our comprehensive services that go beyond our core business of collecting and disposing of waste in order to meet their needs. This includes expanding traditional recycling services, increasing organics collection and processing, providing medical waste services and expanding our renewable energy projects to meet the evolving needs of our diverse customer base. As North America's leading provider of comprehensive environmental solutions, we are taking big, bold steps to catalyze positive change – change that will impact our Company as well as the communities we serve. Consistent with our Company's long-standing commitment to sustainability and environmental stewardship, we have published our 2025 Sustainability Report, providing details on our sustainability-related performance and outlining progress towards our 2030 sustainability goals. The Sustainability Report conveys the strong linkage between the Company's sustainability goals and our growth strategy, inclusive of the expansion of the Company's Recycling Processing and Sales and Renewable Energy segments. The information in this report can be found at sustainability.wm.com but it does not constitute a part of, and is not incorporated by reference into, this Annual Report on Form 10-K. For further discussion see Item 1. *Business – Regulation – Recent Developments and Focus Areas in Policy and Regulation*.

We encounter intense competition from governmental, quasi-governmental and private service providers based on pricing, and to a much lesser extent, the nature of service offerings, particularly in the residential line of business. Our industry is directly affected by changes in general economic factors, including increases and decreases in consumer spending, business expansions and construction activity. These factors generally correlate to volumes of waste generated and impact our revenue. Negative economic conditions and other macroeconomic trends can and have caused customers to reduce their service needs. Such negative economic conditions, in addition to competitor actions, can impact our strategy to negotiate, renew, or expand service contracts and grow our business. We also encounter competition for acquisitions and growth opportunities. General economic factors and the market for consumer goods, in addition to regulatory developments, can also significantly impact commodity prices for the recyclable materials we sell. Significant components of our operating expenses vary directly as we experience changes in revenue due to volume and inflation. Volume changes can fluctuate significantly by line of business and volume changes in higher margin businesses can impact key financial metrics. We must dynamically manage our cost structure in response to volume changes and cost inflation.

We believe the Company's industry-leading asset network and strategic focus on investing in our people and our digital platform will give the Company the necessary tools to address the evolving challenges impacting the Company and our industry. In line with our commitment to continuous improvement and a differentiated customer experience, we remain focused on our automation and optimization investments to enhance our operational efficiency and change the way we interact with our customers. Advancements made through these initiatives are intended to seamlessly and digitally connect all enterprise functions required to service customers and provide the best experience. We have made significant progress in executing this technology enablement strategy to automate and optimize certain elements of our service delivery model. The key benefits are reduced labor dependency on certain high-turnover jobs, particularly in customer experience, recycling and residential collection, while further elevating our customer self-service through digitalization and implementation of technologies to enhance the safety, reliability and efficiency within our collection operations.

We sometimes experience margin pressures and variability in earnings and margins from our commodity-driven businesses, specifically within our Recycling Processing and Sales and Renewable Energy segments. During 2025, we

[**Table of Contents**](#TOC)

experienced decreases in market prices for recycled commodities when compared to prior year caused by a number of factors, including the closure of domestic paper mills, a decrease in demand for recycled content by certain consumer goods producers, focused reduction in cardboard packaging and overall market conditions. While the combined impacts of commodity price fluctuations from the prior year had a modestly favorable impact on the Renewable Energy segment, we may experience more significant impacts from fluctuations in the prices of RINs and natural gas in the future. We continue to take proactive steps to adjust our business models to protect against the down-side risk of changes in commodity prices.

Variability in economic conditions, including inflation, interest rates, employment trends and supply chain reliability, can create risk and uncertainty in financial outlook. We take proactive steps to recover and mitigate inflationary cost pressures through our overall pricing efforts and by managing our costs through efficiency, labor productivity and investments in technology to automate certain aspects of our business. We remain committed to putting our people first to ensure that they are well positioned to execute our daily operations diligently and safely. We remain focused on delivering outstanding customer service, managing our variable costs with changing volumes and investing in technology that will enhance our customers' experience and provide operating efficiencies intended to reduce our cost to serve.

***Financial Results***

During 2025, we continued to focus on our priorities to advance our strategy – enhancing employee engagement, permanently reducing our cost to serve our customers through the use of technology and automation, investing in growth through our Recycling Processing and Sales and Renewable Energy segments and integrating the Stericycle business. We continue to invest in our people through paying a competitive market wage, investing in our digital platform and providing training for our team members. We remain committed to our investment in recycling automation, which reduces costs and increases throughput, positioning us to overcome commodity price headwinds and deliver a differentiated service. As part of the ongoing integration of Stericycle, which constitutes our Healthcare Solutions segment, we achieved synergies by reducing costs of duplicative business processes, established a performance management approach aimed at accountability and continued to improve customer engagement, billing and collection processes to deliver cash flow.

Key elements of our 2025 financial results include:

● Revenues of $25,204 million for 2025 compared with $22,063 million in 2024, an increase of $3,141 million, or 14.2%. The increase was primarily due to (i) our recent acquisitions, particularly Stericycle; (ii) higher yield in our Collection and Disposal businesses and (iii) higher volumes primarily in our landfill, renewable energy and recycling businesses. The increase was partially offset by lower residential collection volumes and a reduction in single-stream and brokerage recycled commodity prices;

● Operating expenses of $15,012 million in 2025, or 59.6% of revenues, compared with $13,383 million, or 60.7% of revenues, in 2024. The $1,629 million increase in operating expense compared to prior year related primarily to (i) our recent acquisitions, particularly Stericycle; (ii) incremental costs attributable to RNG facilities brought on line during 2025; (iii) increased landfill volumes and (iv) a decrease in the gains on sale of non-strategic assets. These increases were offset by (i) lower residential volumes; (ii) decreased costs of goods sold due to lower recycling commodity prices and (iii) continued efficiency and cost control in our Collection and Disposal business. Despite the increase in operating expenses, we significantly reduced our operating expenses as a percentage of revenue when compared to prior year through efficiency gains, improved employee turnover, momentum in truck deliveries, the benefit of customer price increases and higher margin special waste volumes;

● Selling, general and administrative expenses of $2,722 million in 2025, or 10.8% of revenues, compared with $2,264 million, or 10.3% of revenues, in 2024. The $458 million increase was primarily due to our recent acquisitions, particularly Stericycle, including consulting and technology costs incurred to support Stericycle's integration;

● Income from operations of $4,308 million, or 17.1% of revenues, in 2025 compared with $4,063 million, or 18.4% of revenues, in 2024. The $245 million increase in the current year earnings was primarily due to (i) growth in our Collection and Disposal businesses; (ii) non-recurring transaction costs incurred in the prior year in connection with our Stericycle acquisition and (iii) higher volumes in our Renewable Energy business due to the completion of projects that increase the beneficial use of landfill gas sold to third parties. This growth was

[**Table of Contents**](#TOC)

partially offset by an impairment charge in our Recycling Processing and Sales business and higher depreciation and amortization costs and integration related expenses arising from our Stericycle acquisition;

● Net income attributable to Waste Management, Inc. was $2,708 million, or $6.70 per diluted share, compared with $2,746 million, or $6.81 per diluted share, in 2024. The $38 million decrease is primarily due to an increase in interest expense related to the additional debt incurred to finance our Stericycle acquisition. This decline was partially offset by the increase in income from operations, discussed above;

● Net cash provided by operating activities was $6,043 million in 2025, compared with $5,390 million in 2024. The $653 million increase in net cash provided by operating activities was primarily due to (i) higher earnings in our Collection and Disposal businesses; (ii) contributions from our recent acquisitions and (iii) lower cash tax payments. This increase was partially offset by (i) higher cash interest payments primarily due to additional debt incurred to fund our acquisition of Stericycle; (ii) unfavorable changes in working capital, net of effects from acquisitions and divestitures and (iii) higher annual incentive compensation payments;

● Free cash flow was $2,937 million in 2025, compared with $2,317 million in 2024. The $620 million increase in free cash flow was primarily due to the increases in operating cash described above and planned reductions in capital investment in our sustainability growth projects as we move from peak construction of this portfolio into a period where we will harvest strong returns on these businesses. These increases were partially offset by increased capital expenditures to support the business as well as within our Healthcare Solutions segment and lower proceeds from the sale of certain non-strategic assets. Free cash flow is a non-GAAP measure of liquidity. Refer to Free Cash Flow below for our definition of free cash flow, additional information about our use of this measure, and a reconciliation to net cash provided by operating activities, which is the most comparable GAAP measure.

&nbsp;&nbsp;&nbsp;&nbsp;(a) Includes each segment's intercompany activity, including transactions 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.

&nbsp;&nbsp;&nbsp;&nbsp;(b) In the third quarter of 2025, as a result of continued integration efforts and to enhance transparency and accountability, the Company began reflecting intra-segment activity within our Healthcare Solutions segment. These charges were designed to measure profitability at more granular levels of the enterprise and to facilitate clearer financial accountability within operating units. Accordingly, adjustments to the years ended December 31, 2025 and 2024 activity were made to properly reflect intra-segment activity for both periods. Intra-segment operating revenues within Healthcare Solutions for the years ended December 31, 2025 and 2024 are $425 million and $58 million, respectively.

Our overall pricing efforts are focused on keeping pace with the increasing costs and capital intensity of our business. We continue to focus on yield growth in our landfill business. This growth was primarily driven by municipal solid waste, which achieved yield of 6.5% in 2025.

*Recycling Processing and Sales and Renewable Energy —* Recycling Processing and Sales revenues attributable to yield decreased $166 million in 2025 as compared to prior year. Average market prices for single-stream recycled commodities declined approximately 20% in 2025 as compared to the prior year. Revenues attributable to yield in our Renewable Energy segment increased $11 million in 2025 as compared to prior year primarily driven by increases in natural gas and electricity pricing partially offset by declines in RINs pricing. While there may be short-term fluctuations in our commodity-driven businesses as prices change, we believe that our business models and processes appropriately mitigate the downside risk of changes in commodity prices.

*Energy Surcharge and Mandated Fees —* These fees increased $44 million as compared to prior year. Mandated fees increased $33 million while fluctuations in energy surcharges drove an increase of $11 million as compared to prior year. The mandated fees are primarily related to fees and taxes assessed by various state, county and municipal government agencies at our landfills and transfer stations, particularly in our West Tier as a result of wildfire activity.

*Volume*

Our revenues from volume (excluding volumes from acquisitions and divestitures) increased $206 million, or 0.9%, in 2025 as compared to prior year. Volume growth during 2025 was led by our landfill business, with notable increases in special waste and municipal solid waste volumes in the West Tier, particularly driven by wildfire clean-up efforts. Contributions from growth projects also drove gains in our Renewable Energy and Recycling Processing and Sales segments, and volumes in our Strategic Business Solutions business continued to see growth due to our differentiated service model. These gains were partially offset by declines in residential collection volumes, reflecting our strategic exit from lower-margin contracts.

*Acquisitions and Divestitures*

Acquisitions and divestitures resulted in a net increase in revenues of $2,334 million, or 10.6%, in 2025 as compared to prior year. The increase was primarily due to our acquisition of Stericycle in November 2024. The remaining increase was primarily related to our ongoing investment in tuck-in acquisitions of collection and disposal businesses.

#### Operating Expenses
Our operating expenses are comprised of (i) labor and related benefits costs (excluding labor costs associated with maintenance and repairs discussed below), which include salaries and wages, bonuses, related payroll taxes, insurance and benefits costs and the costs associated with contract labor; (ii) transfer and disposal costs, which include tipping fees paid to third-party disposal facilities and transfer stations; (iii) maintenance and repairs costs relating to equipment, vehicles

[**Table of Contents**](#TOC)

and facilities and related labor costs; (iv) subcontractor costs, which include the costs of independent haulers who transport waste collected by us to disposal facilities and are affected by variables such as volumes, distance and fuel prices; (v) cost of goods sold, which includes the cost to purchase recycling materials for our Recycling Processing and Sales segment, including certain rebates paid to suppliers; (vi) fuel costs, net of tax credits for alternative fuel, which represent the costs of fuel to operate our truck fleet and landfill operating equipment; (vii) disposal and franchise fees and taxes, which include landfill taxes, municipal franchise fees, host community fees, contingent landfill lease payments and royalties; (viii) landfill operating costs, which include interest accretion on landfill liabilities, interest accretion on and discount rate adjustments to environmental remediation liabilities, leachate and methane collection and treatment, landfill remediation costs and other landfill site costs; (ix) risk management costs, which include general liability, automobile liability and workers' compensation claims programs costs and (x) other operating costs, which include gains and losses on sale of assets, telecommunications, equipment and facility lease expenses, property taxes, utilities and supplies. Variations in volumes year-over-year, as discussed above in *Operating Revenues*, in addition to cost inflation, affect the comparability of the components of our operating expenses.

The following table summarizes the major components of our operating expenses for the year ended December 31 (dollars in millions and as a percentage of revenues):

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | **2025** | **2025** | **2024** | **2024** |
| Labor and related benefits | $4476 | 17.8% | $3845 | 17.4% |

During 2025, efficiency gains, improved employee turnover, momentum in truck deliveries, the benefit of customer price increases and higher margin special waste volumes, positioned us to significantly reduce our operating expenses as a percentage of operating revenue. The increase in total operating expenses as compared to prior year related primarily to (i) our recent acquisitions, particularly Stericycle; (ii) incremental costs attributable to RNG facilities brought on line during 2025; (iii) increased landfill volumes and (iv) a decrease in gains on the sale of non-strategic assets in 2025. These increases were partially offset by (i) lower residential volumes; (ii) decreased cost of goods sold attributable to lower recycling commodity prices and (iii) continued operating efficiency and cost control initiatives in our Collection and Disposal businesses.

Significant items affecting the comparison of operating expenses between reported periods include:

*Labor and Related Benefits* — The increase in labor and related benefits costs was driven by the addition of employees as a result of our recent acquisitions and annual employee wage increases. These increases were offset in part, by (i) lower annual incentive compensation and employee benefit expenses; (ii) collection efficiency improvements; (iii) lower residential volumes attributable to intentional shedding of lower margin contracts and (iv) improved driver retention.

*Transfer and Disposal Costs* — The increase in transfer and disposal costs was primarily due to our recent acquisitions and inflationary cost pressures, which includes increased disposal fees at third-party sites and higher rates from our third-party haulers. These increases were offset, in part, by lower residential volumes attributable to intentional shedding of lower margin contracts.

*Maintenance and Repairs* — The increase in maintenance and repairs costs was primarily due to (i) additional costs incurred as part of our recent acquisitions; (ii) inflation in parts, supplies and third-party services; (iii) annual wage

[**Table of Contents**](#TOC)

increases and (iv) higher technician headcount. These increases were offset, in part, by an increase in new truck deliveries, which lowered the average fleet age and reduced demand for parts, supplies and third-party services.

*Subcontractor Costs* — The increase in subcontractor costs was primarily due to additional costs incurred as a part of our recent acquisitions and inflationary cost pressures, particularly labor costs from third-party haulers.

*Cost of Goods Sold —* The decrease in cost of goods sold was primarily due to a nearly 20% decrease in average market prices for single-stream recycling commodities. This decrease was partially offset by additional pipeline transportation costs attributable to new RNG facilities brought on line during 2025.

*Fuel —* The increase in fuel costs was primarily due to our recent acquisitions and the expiration of the federal alternative fuel tax credit on December 31, 2024. This increase was partially offset by a decrease of approximately 3% in average market prices for diesel fuel and reduced diesel consumption due to declines in residential collection volumes.

*Disposal and Franchise Fees and Taxes —* The increase in disposal and franchise fees and taxes was primarily due to an increase in landfill volumes and an overall rate increase in fees and taxes paid to municipalities on our disposal volumes.

*Landfill Operating Costs —* The increase in landfill operating costs was primarily due to an increase in volumes and higher leachate treatment costs in our West Tier.

*Risk Management* — The increase in risk management costs was primarily due to additional claims and premiums attributable to our recent acquisitions and higher insurance recoveries for property claims in the prior year as compared to 2025 offset, in part, by improved claims experience.

*Other* — The increase in other operating costs was primarily due to (i) additional expenses attributable to our recent acquisitions; (ii) gains on the sale of real estate in 2024 and, to a much lesser extent, (iii) increased utility costs and property taxes largely attributable to new RNG plants brought on line during 2025.

#### Selling, General and Administrative Expenses
Our selling, general and administrative expenses consist of (i) labor and related benefits costs, which include salaries, bonuses, related insurance and benefits, contract labor, payroll taxes and equity-based compensation; (ii) professional fees, which include fees for consulting, legal, audit and tax services; (iii) provision for bad debts, which includes allowances for uncollectible customer accounts and collection fees and (iv) other selling, general and administrative expenses, which include, among other costs, facility-related expenses, voice and data telecommunication, advertising, bank charges, computer costs, travel and entertainment, rentals, postage and printing. In addition, the financial impacts of litigation reserves generally are included in our "Other" selling, general and administrative expenses.

The following table summarizes the major components of our selling, general and administrative expenses for the year ended December 31 (dollars in millions and as a percentage of revenues):

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | **2025** | **2025** | **2024** | **2024** |
| Labor and related benefits | $1655 | 6.5% | $1400 | 6.4% |
| Professional fees | 398 | 1.6 | 358 | 1.6 |
| Provision for bad debts | 93 | 0.4 | 51 | 0.2 |
| Other | 576 | 2.3 | 455 | 2.1 |
|  | $2722 | 10.8% | $2264 | 10.3% |

---

Selling, general and administrative expenses increased from prior year primarily due to our recent acquisitions, particularly Stericycle.

[**Table of Contents**](#TOC)

Significant items affecting the comparison of our selling, general and administrative expenses between reported periods include:

*Labor and Related Benefits* — The increase in labor and related benefits costs was primarily due to (i) our recent acquisitions; (ii) higher long-term incentive compensation costs and (iii) annual employee wage increases. These increases were partially offset by lower annual incentive compensation and employee benefit expense.

*Professional Fees* — The increase in professional fees was primarily due to our acquisition and integration of Stericycle.

*Provision for Bad Debts* — The increase in the provision for bad debts was primarily attributable to our Healthcare Solutions segment, driven by data and system challenges, and an overall increase in revenue and increase in customer account write-offs.

*Other —* The increase in other expenses was primarily due to increased spend across multiple cost categories, including technology, risk management and advertising, largely driven by the acquisition and integration of Stericycle.

#### Depreciation, Depletion and Amortization Expenses
The following table summarizes the components of our depreciation, depletion and amortization expenses for the year ended December 31 (dollars in millions and as a percentage of revenues):

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | **2025** | **2025** | **2024** | **2024** |
| Depreciation of tangible property and equipment | $1544 | 6.1% | $1292 | 5.9% |
| Depletion of landfill airspace | 898 | 3.6 | 795 | 3.6 |
| Amortization of intangible assets | 421 | 1.7 | 180 | 0.8 |
|  | $2863 | 11.4% | $2267 | 10.3% |

---

The increase in depreciation of tangible property and equipment was primarily due to our recent acquisitions and increased investments in capital assets such as equipment, primarily within our sustainability businesses, and trucks. The increase in depletion of landfill airspace from prior year was primarily due to increased volumes at our landfills, particularly in our West Tier, and changes in amortization rates from revisions in landfill estimates. The increase in amortization of intangible assets from prior year was primarily due to the incremental amortization of customer relationships and other intangibles acquired as part of the Stericycle acquisition.

***Restructuring***

Restructuring charges for the year ended December 31, 2025 were primarily due to employee costs related to integration of our acquisition of Stericycle as well as employee retention and severance costs incurred to support automation at our recycling facilities and in certain back-office functions.

&nbsp;&nbsp;&nbsp;&nbsp;(Gain) Loss from Divestitures, Asset Impairments and Unusual Items, Net

| Asset impairments | 232 | 90 |
| Other, net | 16 | 18 |
|  | $248 | $82 |

---

During the year ended December 31, 2025, we recognized $248 million of net charges primarily consisting of (i) a $160 million impairment charge related to the decision to temporarily suspend the operations of a business engaged in

[**Table of Contents**](#TOC)

accelerating plastic film and wrap recycling capabilities within our Recycling Processing and Sales segment resulting from significant deterioration of market pricing and demand for post-consumer plastics; (ii) a $45 million impairment charge related to the decision to accelerate the closure of a landfill within our East Tier; (iii) a $16 million goodwill impairment charge related to a business engaged in oil recovery and sludge processing services reflected in Other Ancillary within our Collection and Disposal businesses and (iv) $11 million negotiated payment for early termination of a contract in our Renewable Energy segment.

During the year ended December 31, 2024, we recognized $82 million of net charges primarily consisting of (i) a $54 million charge required to increase the estimated fair value of a liability associated with the expected disposition of an investment the Company holds in a waste diversion technology business; (ii) a $14 million loss associated with the divestiture of a minority investment in a medical waste company within Corporate and Other, in connection with our acquisition of Stericycle and (iii) a $13 million charge pertaining to reserves for loss contingencies in our Corporate and Other segment to adjust an indirect wholly-owned subsidiary's estimated potential share of the liability for a proposed environmental remediation plan at a closed site.

See Note 2 to the Consolidated Financial Statements for additional information related to the accounting policy and analysis involved in identifying and calculating impairments.

| Percentage of revenues | 17.1% | 18.4% |  |  |

---

\* Percentage change does not provide a meaningful comparison.

Significant items affecting the comparison of income from operations for our segments between the reported periods include:

● *Collection and Disposal —* Income from operations in our Collection and Disposal businesses increased primarily due to (i) revenue growth from price increases, which translate into increased yield or average unit price; (ii) actions to improve the efficiency and operating costs incurred to serve our customers and (iii) elevated special waste volume in our West Tier, which was favorably impacted by the wildfire clean-up activities. These increases were partially offset by higher depreciation and depletion costs, as discussed in Depreciation, Depletion and Amortization Expenses above, as well as a decrease on the gains on the sale of non-strategic assets when compared to prior year.

● *Recycling Processing and Sales* — Income from operations in our Recycling Processing and Sales segment decreased primarily due to a $160 million impairment charge related to the decision to temporarily suspend the operations of a business engaged in accelerating plastic film and wrap recycling capabilities due to significant deterioration of market pricing and demand for post-consumer plastics and declining commodity prices compared

[**Table of Contents**](#TOC)

to prior year. This decrease was partially offset by increased volumes, which can be attributed to the improved throughput of our facilities, the addition of new market facilities and improved operating costs from the automation of our recycling facilities.

● *Renewable Energy* — Income from operations in our Renewable Energy segment increased primarily due to higher volumes resulting from the completion of projects that increase the beneficial use of landfill gas sold to third parties and higher electricity pricing.

● *Healthcare Solutions* — The positive earnings contributions from the Healthcare Solutions business were more than offset by depreciation and amortization expenses and integration related expenses, driving a loss in both periods.

● *Corporate and Other* — Income from operations in our Corporate and Other segment increased primarily due to (i) non-recurring transaction costs incurred in the prior year in connection with our Stericycle acquisition; (ii) lower annual incentive compensation, and (iii) a decline in risk management expenses. The increase was partially offset by (i) annual employee wage increases; (ii) higher long term incentive compensation and (iii) increases in consulting fees driven by integration and business optimization activities related to the acquisition of Stericycle.

#### Interest Expense, Net
Our interest expense, net was $912 million and $598 million in 2025 and 2024, respectively. The increase in interest expense, net was primarily related to an increase in our average debt balances and borrowing rates resulting from debt incurred to fund our acquisition of Stericycle. See Note 6 to the Consolidated Financial Statements for more information related to our debt balances.

#### Income Tax Expense
We recorded income tax expense of $717 million and $713 million in 2025 and 2024, respectively, resulting in effective income tax rates of 20.9% and 20.6% for the years ended December 31, 2025 and 2024, respectively. The comparability of our income tax expense for the reported periods has been primarily affected by the following:

● *Renewable Natural Gas —* Through our Renewable Energy segment, we have invested in building landfill gas-to-energy facilities in the U.S. and Canada that produce renewable electricity and RNG. We expect our new RNG facilities to qualify for federal tax credits and to realize those credits through 2027 under Section 48 of the Internal Revenue Code. We completed construction of seven RNG facilities in 2025 and five RNG facilities in 2024, resulting in a reduction to our income tax expense of $184 million and $137 million, respectively (additional information related to these tax credits is included below under the Tax Legislation section);

● *Low-Income Housing* — During the years ended December 31, 2025 and 2024, we recognized income tax expense of $96 million and $78 million, respectively, related to amortization under ASU 2023-02, and a reduction in our income tax expense of $137 million and $104 million, respectively, primarily due to federal tax credits realized from these investments. See Notes 2, 8, and 18 to the Consolidated Financial Statements for additional information related to these unconsolidated variable interest entities;

● *Tax Implications of Impairments* — During the year ended December 31, 2024, we recognized additional income tax expense of $14 million due to non-cash impairment charges that were not deductible for tax purposes in the year of impairment. See Note 11 to the Consolidated Financial Statements for more information related to our impairment charges; and

● *Tax Legislation* — On July 4, 2025, President Trump signed the One Big Beautiful Bill Act (the "OBBBA") into law. We have evaluated the business tax provisions in the legislation, none of which had a material impact on our effective tax rate. However, we had a beneficial impact to cash taxes related to bonus depreciation.

The Inflation Reduction Act of 2022 ("IRA") contains several tax-related provisions, including with respect to (i) alternative fuel tax credits; (ii) tax incentives for investments in renewable energy production, carbon capture,

[**Table of Contents**](#TOC)

and other climate actions and (iii) the overall measurement of corporate income taxes. Given the complexity and uncertainty around the applicability of the legislation to our specific facts and circumstances, we continue to analyze the IRA provisions to identify and quantify potential opportunities and applicable benefits included in the legislation. The provisions of the IRA related to alternative fuel tax credits secured approximately $60 million of annual pre-tax benefit (recorded as a reduction in our operating expense) from tax credits in 2024. The alternative fuel credit expired at the end of 2024 and will not provide any future benefit to the Company without further legislative action. With respect to the investment tax credit, we expect the cumulative benefit to be between $400 million and $425 million, the remainder of which we expect to recognize through 2027. The expected benefit from the investment tax credit is dependent on a number of estimates and assumptions, including the timing of project completion. Finally, we believe that the production tax credit incentives for investments in renewable energy and carbon capture, as expanded by the IRA, may result in an incremental benefit to the Company, although at this time, the anticipated amount of such benefit has not been quantified due, in part, to the lack of regulatory guidance.

See Note 8 to the Consolidated Financial Statements for more information related to income taxes.

#### Landfill and Environmental Remediation Discussion and Analysis
We owned or operated 253 solid waste landfills and four hazardous waste landfills as of December 31, 2025 and 257 solid waste landfills and five hazardous waste landfills as of December 31, 2024. For these landfills, the following table reflects changes in capacity, as measured in tons of waste, for the year ended December 31 and remaining airspace, measured in cubic yards of waste, as of December 31 (in millions):

---

| | | | | | | |
|:---|:---|:---|:---|:---|:---|:---|
|  | **2025** | **2025** | **2025** | **2024** | **2024** | **2024** |

| Balance as of end of year (in cubic yards) (d) | 4982 | 144 | 5126 | 5049 | 165 | 5214 |

---

&nbsp;&nbsp;&nbsp;&nbsp;(a) Amounts reflected here relate to the combined impacts of (i) new expansions pursued; (ii) increases or decreases in the airspace being pursued for ongoing expansion efforts; (iii) adjustments for differences between the airspace being pursued and airspace granted and (iv) decreases due to decisions to no longer pursue expansion permits, if any.

&nbsp;&nbsp;&nbsp;&nbsp;(b) We received expansion permits at 13 of our landfills during 2025 and 11 of our landfills during 2024, demonstrating our continued success in working with municipalities and regulatory agencies to expand the disposal airspace of our existing landfills.

&nbsp;&nbsp;&nbsp;&nbsp;(c) Changes in engineering estimates can result in changes to the estimated available remaining airspace of a landfill or changes in the utilization of such landfill airspace, affecting the number of tons that can be placed in the future. Estimates of the amount of waste that can be placed in the future are reviewed annually by our engineers and are based on a number of factors, including standard engineering techniques and site-specific factors such as current and projected mix of waste type; initial and projected waste density; estimated number of years of life remaining; depth of underlying waste; anticipated access to moisture through precipitation or recirculation of landfill leachate and operating practices. We continually focus on improving the utilization of airspace through efforts that may include recirculating landfill leachate where allowed by permit; optimizing the placement of daily cover materials and increasing initial compaction through improved landfill equipment, operations and training.

&nbsp;&nbsp;&nbsp;&nbsp;(d) See Note 2 to the Consolidated Financial Statements for discussion of converting remaining cubic yards of airspace to tons of capacity.

[**Table of Contents**](#TOC)

The depletable tons received at our landfills for the year ended December 31 are shown below (tons in thousands):

|  |  | 128819 |  |  | 125010 |  |

---

&nbsp;&nbsp;&nbsp;&nbsp;(a) As of December 31, 2025 and 2024, we had 16 and 15 landfills, respectively, which were not accepting waste.

As of December 31, 2025, we owned or managed 244 sites that are either in closure or post-closure, have received a certification post-closure, or are regulated under a remedial action plan.

Based on remaining permitted airspace as of December 31, 2025 and projected annual disposal volume, the weighted average remaining landfill life for all of our owned or operated landfills is approximately 38 years. Many of our landfills have the potential for expanded airspace beyond what is currently permitted. We monitor the availability of permitted airspace at each of our landfills and evaluate whether to pursue an expansion at a given landfill based on estimated future disposal volume, disposal prices, construction and operating costs, remaining airspace and likelihood of obtaining an expansion permit. We are seeking expansion permits at 15 of our landfills that meet the expansion criteria outlined in the *Critical Accounting Estimates and Assumptions — Landfills* section below. Although no assurances can be made that all future expansions will be permitted or permitted as designed, the weighted average remaining landfill life for all owned or operated landfills is approximately 39 years when considering remaining permitted airspace, expansion airspace and projected annual disposal volume.

The number of landfills owned or operated as of December 31, 2025, segregated by their estimated operating lives based on remaining permitted and expansion airspace and projected annual disposal volume, was as follows:

---

| | |
|:---|:---|
|  | **# of Landfills** |
| 0 to 5 years | 24 |
| 6 to 10 years | 23 |
| 11 to 20 years | 55 |
| 21 to 40 years | 61 |
| 41+ years | 94 |
| &nbsp;&nbsp;&nbsp;&nbsp;Total | 257<br> (a) |

---

&nbsp;&nbsp;&nbsp;&nbsp;(a) Of the 257 landfills, 219 are owned, 26 are operated under lease agreements and 12 are operated under other contractual agreements. For the landfills not owned, we are usually responsible for final capping, closure and post-closure obligations.

*Landfill Assets —* We capitalize various costs that we incur to prepare a landfill to accept waste. These costs generally include expenditures for land (including the landfill footprint and required landfill buffer property), permitting, excavation, liner material and installation, landfill leachate collection systems, landfill gas collection systems, environmental monitoring equipment for groundwater and landfill gas, directly related engineering, capitalized interest, and on-site road construction and other capital infrastructure costs. The cost basis of our landfill assets also includes estimates of future costs associated with landfill final capping, closure and post-closure activities, which are discussed further below.

[**Table of Contents**](#TOC)

The changes to the cost basis of our landfill assets and accumulated landfill airspace depletion for the year ended December 31, 2025 are reflected in the table below (in millions):

| December 31, 2025 | $21176 | $(12944) | $8232 |

---

As of December 31, 2025, we estimate that we will spend approximately $874 million in 2026, and approximately $1.8 billion in 2027 and 2028 combined, for the construction and development of our landfill assets. The specific timing of landfill capital spending is dependent on future events and spending estimates are subject to change due to fluctuations in landfill waste volumes, changes in environmental requirements and other factors impacting landfill operations.

*Landfill and Environmental Remediation Liabilities —* As we accept waste at our landfills, we incur significant asset retirement obligations, which include liabilities associated with landfill final capping, closure and post-closure activities. These liabilities are accounted for in accordance with authoritative guidance on accounting for asset retirement obligations and are discussed in Note 2 to the Consolidated Financial Statements. We also have liabilities for the remediation of properties that have incurred environmental damage, which generally was caused by operations or for damage caused by conditions that existed before we acquired operations or a site. We recognize environmental remediation liabilities when we determine that the liability is probable and the cost for the likely remedy can be reasonably estimated.

The changes to landfill and environmental remediation liabilities for the year ended December 31, 2025 are reflected in the table below (in millions):

---

| | | |

---

[**Table of Contents**](#TOC)

*Depletion of Landfill Airspace* — Depletion of landfill airspace, which is included as a component of depreciation, depletion and amortization expenses, includes the following:

● the depletion of landfill capital costs, including (i) costs that have been incurred and capitalized and (ii) estimated future costs for landfill development and construction required to develop our landfills to their remaining permitted and expansion airspace; and

● the depletion of asset retirement costs arising from landfill final capping, closure and post-closure obligations, including (i) costs that have been incurred and capitalized and (ii) projected asset retirement costs.

Depletion expense is recorded on a units-of-consumption basis, applying cost as a rate per ton. The rate per ton is calculated by dividing each component of the depletable basis of a landfill (net of accumulated depletion) by the number of tons needed to fill the corresponding asset's remaining permitted and expansion airspace. Landfill capital costs and closure and post-closure asset retirement costs are generally incurred to support the operation of the landfill over its entire operating life and are, therefore, depleted on a per-ton basis using a landfill's total permitted and expansion airspace. Final capping asset retirement costs are related to a specific final capping event and are, therefore, depleted on a per-ton basis using each discrete final capping event's estimated permitted and expansion airspace. Accordingly, each landfill has multiple per-ton depletion rates.

The following table presents our landfill airspace depletion expense on a per-ton basis for the year ended December 31:

---

| | | |
|:---|:---|:---|
|  | **2025** | **2024** |
| Depletion of landfill airspace (in millions) | $898 | $795 |
| Tons received, net of redirected waste (in millions) | 129 | 125 |
| Average landfill airspace depletion expense per ton | $6.96 | $6.36 |

---

Different per-ton depletion rates are applied at each of our 257 landfills, and per-ton depletion rates vary significantly from one landfill to another due to (i) inconsistencies that often exist in construction costs and provincial, state and local regulatory requirements for landfill development and landfill final capping, closure and post-closure activities and (ii) differences in the cost basis of landfills that we develop versus those that we acquire. Accordingly, our landfill airspace depletion expense measured on a per-ton basis can fluctuate due to changes in the mix of volumes we receive across the Company each year.

[**Table of Contents**](#TOC)

**Liquidity and Capital Resources** 

The Company consistently generates annual cash flow from operations that meets and exceeds our working capital needs, allows for payment of our dividends, investment in the business through capital expenditures and tuck-in acquisitions and funding of strategic sustainability growth investments. We continually monitor our actual and forecasted cash flows, our liquidity and our capital resources, enabling us to plan for our present needs and fund unbudgeted business requirements that may arise during the year. The Company believes that its investment grade credit ratings, diverse investor base, large value of unencumbered assets and modest leverage enable it to obtain adequate financing, and refinance upcoming maturities, as necessary to meet its ongoing capital, operating, strategic and other liquidity requirements. We also have the ability to manage liquidity during periods of significant financial market disruption through temporary modification of our capital expenditure and share repurchase plans.

***Summary of Contractual Obligations***

The following table summarizes our significant contractual obligations as of December 31, 2025 (other than recorded obligations related to liabilities associated with environmental remediation costs and non-cancelable operating lease obligations, which are discussed further in Notes 3 and 7 to the Consolidated Financial Statements, respectively) and the anticipated effect of these obligations on our liquidity in future years (in millions):

---

&nbsp;&nbsp;&nbsp;&nbsp;(a) Includes liabilities for final capping, closure and post-closure costs recorded in our Consolidated Balance Sheet as of December 31, 2025, without the impact of discounting and inflation. Our recorded liabilities for final capping, closure and post-closure costs will increase as we continue to place additional tons within the permitted airspace at our landfills.

&nbsp;&nbsp;&nbsp;&nbsp;(b) These amounts represent the scheduled principal payments based on their contractual maturities related to our long-term debt and financing leases, excluding interest. Refer to Note 6 to the Consolidated Financial Statements for additional information regarding our debt obligations.

&nbsp;&nbsp;&nbsp;&nbsp;(c) Interest on our fixed-rate debt was calculated based on contractual rates and interest on our variable-rate debt was calculated based on interest rates as of December 31, 2025. As of December 31, 2025, we had $233 million of accrued interest related to our debt obligations.

&nbsp;&nbsp;&nbsp;&nbsp;(d) Our obligations represent purchase commitments from which we expect to realize an economic benefit in future periods. We have also made certain guarantees that we do not expect to materially affect our current or future financial position, results of operations or liquidity. See Note 10 to the Consolidated Financial Statements for discussion of the nature and terms of our unconditional purchase obligations and guarantees.

&nbsp;&nbsp;&nbsp;&nbsp;(a) As of December 31, 2025 and 2024, $109 million and $100 million, respectively, of these account balances was included in other current assets in our Consolidated Balance Sheets.

*Debt* — We use long-term borrowings in addition to the cash we generate from operations as part of our overall financial strategy to support and grow our business. We primarily use senior notes and tax-exempt bonds to borrow on a long-term basis, but we also use other instruments and facilities, when appropriate. The components of our borrowings as of December 31, 2025 are described in Note 6 to the Consolidated Financial Statements.

As of December 31, 2025, we had approximately $3.7 billion of debt maturing within the next 12 months, including (i) $1.8 billion of tax-exempt bonds with term interest rate periods that expire within the next 12 months, which is prior to their scheduled maturities; (ii) $1.1 billion of short-term borrowings under our commercial paper program (net of related discount on issuance); (iii) $223 million of 7.1% senior notes that mature in August 2026; (iv) $364 million of 2.6% Canadian senior notes that mature in September 2026 and (v) $200 million of other debt with scheduled maturities within the next 12 months. As of December 31, 2025, we have classified $3.0 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"). The remaining $711 million of debt maturing in the next 12 months is classified as current obligations.

We have credit lines in place to support our liquidity and financial assurance needs. The following table summarizes our outstanding letters of credit, categorized by type of facility as of December 31 (in millions):

#### Summary of Cash Flow Activity
The following is a summary of our cash flows for the year ended December 31 (in millions):

---

| | | |
|:---|:---|:---|
|  | **2025** | **2024** |
| Net cash provided by operating activities | $6043 | $5390 |
| Net cash used in investing activities | $(3566) | $(10601) |
| Net cash provided by (used in) financing activities | $(2673) | $5155 |

---

*Net Cash Provided by Operating Activities —* Our operating cash flows increased $653 million in 2025 compared to 2024, primarily due to (i) higher earnings in our Collection and Disposal businesses; (ii) contributions from our recent acquisitions and (iii) lower cash tax payments. This increase was partially offset by (i) higher cash interest payments primarily due to additional debt incurred to fund our acquisition of Stericycle; (ii) higher annual incentive compensation payments and (iii) unfavorable changes in working capital, net of effects from acquisitions and divestitures. We continue to execute well in optimizing working capital, particularly in the reduction of days sales outstanding for our Healthcare Solutions business and alignment of our days-to-pay measure with contract terms, though overall working capital changes have been pressured by the Stericycle acquisition.

*Net Cash Used in Investing Activities —* The most significant items affecting the comparison of our investing cash flows for the periods presented are summarized below:

● *Acquisitions —* Our spending on acquisitions was $404 million and $7,503 million in 2025 and 2024, respectively, of which $395 million and $7,488 million, respectively, are considered cash used in investing activities. The remaining spend is cash used in financing activity related to the timing of contingent consideration paid. Excluding our acquisition of Stericycle in 2024, substantially all of the remaining acquisitions are related to our solid waste and recycling businesses.

● *Capital Expenditures —* We used $3,227 million and $3,231 million for capital expenditures in 2025 and 2024, respectively. The decrease in capital spending in 2025 compared to 2024 is primarily due to planned reductions in capital investment in our sustainability growth projects as we move from peak construction of this portfolio into a period where we will harvest strong returns on these businesses . The decrease in capital spending was mostly offset by increased capital expenditures to support the business and incremental spend within our Healthcare Solutions segment driven by the timing of the acquisition in late 2024.

[**Table of Contents**](#TOC)

● *Divestitures —* Proceeds from divestitures of businesses and other assets, net of cash divested, were $121 million and $158 million in 2025 and 2024, respectively. Proceeds in 2025 primarily related to the sale of our Healthcare Solutions segment's Spain and Portugal subsidiaries. The remaining 2025 and 2024 proceeds were from the sale of certain non-strategic assets.

● *Other, Net —* Our spending within other, net was $65 million and $40 million in 2025 and 2024, respectively. During 2025 and 2024, we used $56 million and $4 million, respectively, of cash from restricted cash and cash equivalents to invest in available-for-sale securities. During 2024, we used $33 million to make initial cash payments associated with a low-income housing investment.

*Net Cash Provided by (Used in) Financing Activities —* The most significant items affecting the comparison of our financing cash flows for the periods presented are summarized below:

● *Debt Borrowings (Repayments) —* The following summarizes our cash borrowings and repayments of debt for the year ended December 31 (in millions):

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) In October 2024, we drew $5.2 billion of borrowings under a term credit agreement that were applied to funding our acquisition of Stericycle. In November 2024, we repaid all outstanding borrowings and contemporaneously terminated the term credit agreement.

Refer to Note 6 to the Consolidated Financial Statements for additional information related to our debt borrowings and repayments.

● *Common Stock Repurchase Program —* For the periods presented, all share repurchases have been made in accordance with financial plans approved by our Board of Directors. No share repurchases were made in 2025. During 2024, we allocated $262 million of available cash to common stock repurchases. See Note 13 to the Consolidated Financial Statements for additional information about our share repurchase activity.

We announced in December 2025 that our Board of Directors has authorized up to $3.0 billion in future share repurchases, exclusive of fees, commissions and taxes. This new authorization supersedes and replaces remaining authority under the prior Board of Directors' authorization for share repurchases announced in December 2023. The amount of future share repurchases executed under our Board of Directors' authorization is determined in management's discretion, based on various factors, including our leverage level, net earnings, financial condition and cash required for future business plans, growth and acquisitions.

● *Cash Dividends —* For the periods presented, all dividends have been declared by our Board of Directors. Cash dividends declared and paid were $1.3 billion in 2025, or $3.30 per common share and $1.2 billion in 2024, or $3.00 per common share.

In December 2025, we announced that our Board of Directors expects to increase the quarterly dividend from $0.825 to $0.945 per share for dividends declared in 2026. However, all future dividend declarations are at the

[**Table of Contents**](#TOC)

discretion of the Board of Directors and depend on various factors, including our leverage level, net earnings, financial condition, cash required for future business plans, growth and acquisitions and other factors the Board of Directors may deem relevant.

● *Exercise of Common Stock Options —* The exercise of common stock options generated financing cash inflows of $61 million and $53 million from the exercise of 676,000 and 693,000 of employee stock options during 2025 and 2024, respectively.

● *Other, Net —* During 2024, we acquired the remaining minority interests in a business engaged in accelerating film and plastic wrap recycling capabilities for $41 million.

#### Free Cash Flow
We are presenting free cash flow, which is a non-GAAP measure of liquidity, in our disclosures because we use this measure in the evaluation and management of our business. We define 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. We believe it is indicative of our ability to pay our quarterly dividends, repurchase common stock, fund acquisitions and other investments and, in the absence of refinancings, to repay our debt obligations. Free cash flow is not intended to replace net cash provided by operating activities, which is the most comparable GAAP measure. We believe free cash flow gives investors useful insight into how we view our 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 we have committed to, such as declared dividend payments and debt service requirements.

Our calculation of free cash flow and reconciliation to net cash provided by operating activities is shown in the table below for the year ended December 31 (in millions), and may not be calculated the same as similarly-titled measures presented by other companies:

---

| | | |
|:---|:---|:---|
|  | **2025** | **2024** |
| Net cash provided by operating activities  | $6043 | $5390 |
| &nbsp;&nbsp;Capital expenditures to support the business | (2594) | (2281) |
| &nbsp;&nbsp;Capital expenditures - sustainability growth investments (a) | (633) | (950) |
| Total capital expenditures | (3227) | (3231) |
| Proceeds from divestitures of businesses and other assets, net of cash divested | 121 | 158 |
| &nbsp;&nbsp;Free cash flow | $2937 | $2317 |

---

&nbsp;&nbsp;&nbsp;&nbsp;(a) These growth investments are intended to further our sustainability leadership position by increasing recycling volumes and growing RNG generation and we expect they will deliver circular solutions for our customers and drive environmental value to the communities we serve.

**Critical Accounting Estimates and Assumptions** 

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. Each of these items is discussed in additional detail below and in Note 2 to the Consolidated Financial Statements. Actual results could differ materially from the estimates and assumptions that we use in the preparation of our financial statements.

[**Table of Contents**](#TOC)

***Landfills***

Accounting for landfills requires that significant estimates and assumptions be made regarding (i) the cost to construct and develop each landfill asset; (ii) the estimated fair value of final capping, closure and post-closure asset retirement obligations, which must consider both the expected cost and timing of these activities and (iii) the determination of each landfill's remaining permitted and expansion airspace.

*Landfill Costs —* We estimate the total cost to develop each of our landfill sites to its remaining permitted and expansion airspace. This estimate includes such costs as landfill liner material and installation, excavation for airspace, landfill leachate collection systems, landfill gas collection systems, environmental monitoring equipment for groundwater and landfill gas, directly related engineering, capitalized interest, on-site road construction and other capital infrastructure costs. Additionally, landfill development includes all land purchases for the landfill footprint and landfill buffer property. The projection of these landfill costs is dependent, in part, on future events. The remaining depletable basis of each landfill includes costs to develop a site to its remaining permitted and expansion airspace and includes amounts previously expended and capitalized, net of accumulated airspace depletion, and projections of future purchase and development costs.

*Final Capping Costs —* We estimate the cost for each final capping event based on the area to be capped and the capping materials and activities required. The estimates also consider when these costs are anticipated to be paid and factor in inflation and discount rates. Our engineering personnel allocate landfill final capping costs to specific final capping events and the capping costs are depleted as waste is disposed of at the landfill. We review these costs annually, or more often if significant facts change. Changes in estimates, such as timing or cost of construction, for final capping events immediately impact the required liability and the corresponding asset. When the change in estimate relates to a fully consumed landfill, the adjustment to the asset must be depleted immediately through expense. When the change in estimate relates to a final capping event at a landfill with remaining airspace, the adjustment to the asset is recognized in income prospectively as a component of landfill airspace depletion.

*Closure and Post-Closure Costs —* We base our estimates for closure and post-closure costs on our interpretations of permit and regulatory requirements for closure and post-closure monitoring and maintenance. The estimates for landfill closure and post-closure costs also consider when the costs are anticipated to be paid and factor in inflation and discount rates. The possibility of changing legal and regulatory requirements and the forward-looking nature of these types of costs make any estimation or assumption less certain. Changes in estimates for closure and post-closure events immediately impact the required liability and the corresponding asset. When the change in estimate relates to a fully consumed landfill, the adjustment to the asset must be depleted immediately through expense. When the change in estimate relates to a landfill with remaining airspace, the adjustment to the asset is recognized in income prospectively as a component of landfill airspace depletion.

*Remaining Permitted Airspace —* Our engineers, in consultation with third-party engineering consultants and surveyors, are responsible for determining remaining permitted airspace at our landfills. The remaining permitted airspace is determined by an annual survey, which is used to compare the existing landfill topography to the expected final landfill topography.

*Expansion Airspace —* We also include currently unpermitted expansion airspace in our estimate of remaining permitted and expansion airspace in certain circumstances. First, for unpermitted airspace to be initially included in our estimate of remaining permitted and expansion airspace, we must believe that obtaining the expansion permit is likely. Second, we must generally expect the initial expansion permit application to be submitted within one year and the final expansion permit to be received within five years, in addition to meeting the following criteria:

● Personnel are actively working on the expansion of an existing landfill, including efforts to obtain land use and local, state or provincial approvals;

● We have a legal right to use or obtain land to be included in the expansion plan;

● There are no significant known technical, legal, community, business, or political restrictions or similar issues that could negatively affect the success of such expansion; and

[**Table of Contents**](#TOC)

● Financial analysis has been completed based on conceptual design, and the results demonstrate that the expansion meets Company criteria for investment.

These criteria are evaluated by our field-based engineers, accountants, managers and others to identify potential obstacles to obtaining the permits. Once the unpermitted airspace is included, our policy provides that airspace may continue to be included in remaining permitted and expansion airspace even if certain of these criteria are no longer met as long as we continue to believe we will ultimately obtain the permit, based on the facts and circumstances of a specific landfill. In these circumstances, continued inclusion must be approved through a landfill-specific review process that includes approval by our Chief Financial Officer on a quarterly basis.

When we include the expansion airspace in our calculations of remaining permitted and expansion airspace, we also include the projected costs for development, as well as the projected asset retirement costs related to final capping, closure and post-closure of the expansion in the depletable basis of the landfill.

Once the remaining permitted and expansion airspace is determined in cubic yards, an airspace utilization factor ("AUF") is established to calculate the remaining permitted and expansion capacity in tons. The AUF is established using the measured density obtained from previous annual surveys and is then adjusted to account for future settlement. The amount of settlement that is forecasted will consider several site-specific factors including current and projected mix of waste type, initial and projected waste density, estimated number of years of life remaining, depth of underlying waste, anticipated access to moisture through precipitation or recirculation of landfill leachate and operating practices. In addition, the initial selection of the AUF is subject to a subsequent multi-level review by our engineering group and the AUF used is reviewed on a periodic basis and revised as necessary. Our historical experience generally indicates that the impact of settlement at a landfill is greater later in the life of the landfill when the waste placed at the landfill approaches its highest point under the permit requirements.

After determining the costs and remaining permitted and expansion capacity at each of our landfills, we determine the per ton rates that will be expensed as waste is received and deposited at the landfill by dividing the costs by the corresponding number of tons. We calculate per ton depletion rates for each landfill for assets associated with each final capping event, for assets related to closure and post-closure activities and for all other costs capitalized or to be capitalized in the future. These rates per ton are updated annually, or more often, as significant facts change.

It is possible that actual results, including the amount of costs incurred, the timing of final capping, closure and post-closure activities, our airspace utilization or the success of our expansion efforts could ultimately turn out to be significantly different from our estimates and assumptions. To the extent that such estimates, or related assumptions, prove to be significantly different than actual results, lower earnings may be experienced due to higher depletion rates or higher expenses; or higher earnings may result if the opposite occurs. Most significantly, if it is determined that expansion capacity should no longer be considered in calculating the recoverability of a landfill asset, we may be required to recognize an asset impairment or incur significantly higher depletion expense. If at any time management makes the decision to abandon the expansion effort, the capitalized costs related to the expansion effort are expensed immediately.

***Environmental Remediation Liabilities***

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.

Where it is probable that a liability has been incurred, we estimate costs required to remediate sites based on site-specific facts and circumstances. We routinely review and evaluate sites that require remediation and determine our estimated cost for the likely remedy based on a number of estimates and assumptions. Next, we review the same type of

[**Table of Contents**](#TOC)

information with respect to other named and unnamed PRPs. Estimates of the costs for the likely remedy are then either developed using our internal resources or by third-party environmental engineers or other service providers. Internally developed estimates are based on:

● Management's judgment and experience in remediating our own and unrelated parties' sites;

● Information available from regulatory agencies as to costs of remediation;

● The number, financial resources and relative degree of responsibility of other PRPs who may be liable for remediation of a specific site; and

● The typical allocation of costs among PRPs, unless the actual allocation has been determined.

Refer to Note 10 to the Consolidated Financial Statements for additional information on our environmental liabilities.

***Fair Value of Nonfinancial Assets and Liabilities***

Significant estimates are made in determining the fair value of long-lived tangible and intangible assets (i.e., property and equipment, intangible assets and goodwill) during the impairment evaluation process. In addition, the majority of assets acquired and liabilities assumed in a business combination are required to be recognized at fair value under the relevant accounting guidance.

Fair value is computed using several factors, including projected future operating results, economic projections, anticipated future cash flows, comparable marketplace data and the cost of capital. There are inherent uncertainties related to these factors and to our judgment in applying them in our analysis. However, we believe our methodology for estimating the fair value of our reporting units is reasonable.

*Property and Equipment, Including Landfills and Definite-Lived Intangible Assets —* We monitor the carrying value of our long-lived assets for potential impairment on an ongoing basis and test the recoverability of such assets generally using significant unobservable ("Level 3") inputs whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. These events or changes in circumstances, including management decisions pertaining to such assets, are referred to as impairment indicators. If an impairment indicator occurs, we perform a test of recoverability by comparing the carrying value of the asset or asset group to its undiscounted expected future cash flows. If cash flows cannot be separately and independently identified for a single asset, we will determine whether an impairment has occurred for the group of assets for which we can identify the projected cash flows. If the carrying values are in excess of undiscounted expected future cash flows, we measure any impairment by comparing the fair value of the asset or asset group to its carrying value and the difference is recorded in the period that the impairment indicator occurs. Fair value is generally determined by considering (i) internally developed discounted projected cash flow analysis of the asset or asset group; (ii) third-party valuations and/or (iii) information available regarding the current market for similar assets. Estimating future cash flows requires significant judgment and projections may vary from the cash flows eventually realized, which could impact our ability to accurately assess whether an asset has been impaired.

The assessment of impairment indicators and the recoverability of our capitalized costs associated with landfills and related expansion projects require significant judgment due to the unique nature of the waste industry, the highly regulated permitting process and the sensitive estimates involved. During the review of a landfill expansion application, a regulator may initially deny the expansion application although the expansion permit is ultimately granted. In addition, management may periodically divert waste from one landfill to another to conserve remaining permitted landfill airspace, or a landfill may be required to cease accepting waste, prior to receipt of the expansion permit. However, such events occur in the ordinary course of business in the waste industry and do not necessarily result in impairment of our landfill assets because, after consideration of all facts, such events may not affect our belief that we will ultimately obtain the expansion permit. As a result, our tests of recoverability, which generally make use of a probability-weighted cash flow estimation approach, may indicate that no impairment loss should be recorded.

[**Table of Contents**](#TOC)

*Indefinite-Lived Intangible Assets, Including Goodwill —* At least annually using a measurement date of October 1, and more frequently if warranted, we assess the indefinite-lived intangible assets including the goodwill of our reporting units for impairment using Level 3 inputs.

We may perform either a qualitative or quantitative assessment; however, if a qualitative assessment is performed and we determine that the fair value of a reporting unit is more likely than not to be less than its carrying amount, a quantitative assessment is performed. The quantitative assessment compares the estimated fair value of a reporting unit to its carrying amount, including goodwill. An impairment charge is recognized if the reporting unit's estimated fair value was less than its carrying amount. Fair value is typically estimated using an income approach using Level 3 inputs. However, when appropriate, we may also use a market approach. The income approach is based on the long-term projected future cash flows of the reporting units. We discount the estimated cash flows to present value using a weighted average cost of capital that considers factors such as market assumptions, the timing of the cash flows and the risks inherent in those cash flows. We believe that this approach is appropriate because it provides a fair value estimate based upon the reporting units' expected long-term performance considering the economic and market conditions that generally affect our business. The market approach estimates fair value by measuring the aggregate market value of publicly-traded companies with similar characteristics to our business as a multiple of their reported earnings. We then apply that multiple to the reporting units' earnings to estimate their fair values. We believe that this approach may also be appropriate in certain circumstances because it provides a fair value estimate using valuation inputs from entities with operations and economic characteristics comparable to our reporting units.

Reporting units within our Healthcare Solutions segment are more sensitive than others to changes in estimated fair values, specifically changes driven by revenue growth, cost and discount rate assumptions, as compared to our other reporting units due to the fact that the Stericycle business comprising these reporting units was recently acquired. As such, the reporting units within our Healthcare Solutions segment have a greater risk of impairment should their operations or market conditions experience a significant downturn.

*Acquisitions* — In accordance with the acquisition method of accounting, the purchase price paid for an acquisition is allocated to the assets and liabilities acquired based upon their estimated fair values as of the acquisition date, with the excess of the purchase price over the net assets acquired recorded as goodwill. When we are in the process of valuing all of the assets and liabilities acquired in an acquisition, there can be subsequent adjustments to our estimates of fair value and resulting preliminary purchase price allocation. Generally, the valuation of our acquired assets and liabilities rely on complex estimates and assumptions.

Acquisition-date fair value estimates are revised as necessary if, and when, additional information regarding these contingencies becomes available to further define and quantify assets acquired and liabilities assumed. Subsequent to finalization of purchase accounting, these revisions are accounted for as adjustments to income from operations. All acquisition-related transaction costs are expensed as incurred. See Note 17 to the Consolidated Financial Statements for additional information related to our acquisitions.

See Item 7. *Management's Discussion and Analysis of Financial Condition and Results of Operations* — *(Gain) Loss from Divestitures, Asset Impairments and Unusual Items, Net*. See Note 11 to the Consolidated Financial Statements for additional information related to Asset Impairments and Unusual Items.

#### Inflation
Variability in economic conditions, including inflation, interest rates, employment trends, and supply chain reliability, can create risk and uncertainty in financial outlook. We take proactive steps to recover and mitigate inflationary cost pressures through our overall pricing efforts and by managing our costs through efficiency, labor productivity, and investments in technology to automate certain aspects of our business. These efforts may not be successful for various reasons including the pace of inflation, operating cost inefficiencies, market responses, and contractual limitations, such as the timing lag in our ability to recover increased costs under certain contracts that are tied to a price escalation index with a lookback provision.

Refer to Item 1A. *Risk Factors* for further discussion.

[**Table of Contents**](#TOC)

#### Item 7A. Quantitative and Qualitative Disclosures about Market Risk.
In the normal course of business, we are exposed to market risks, including changes in interest rates, certain commodity prices and currency rates. From time to time, we use derivatives to manage some portion of these risks. As of December 31, 2025 our outstanding derivatives were immaterial.

*Interest Rate Exposure —* Our exposure to market risk for changes in interest rates relates primarily to our financing activities. As of December 31, 2025 and 2024, we had $22.9 billion and $24.1 billion, respectively, of long-term debt, excluding the impacts of accounting for debt issuance costs, discounts and fair value adjustments attributable to terminated interest rate derivatives. As of December 31, 2025, we have $2.9 billion of debt that is exposed to changes in market interest rates within the next 12 months, compared to $2.7 million as of December 31, 2024, comprised primarily of (i) $1.1 billion of short-term borrowings under our commercial paper program and (ii) $1.8 billion of tax-exempt bonds with term interest rate periods that expire within the next 12 months. We currently estimate that a 100-basis point increase in the interest rates of our outstanding variable-rate debt obligations would increase our 2025 interest expense by $35 million.

Our remaining outstanding debt obligations have fixed interest rates through either the scheduled maturity of the debt or, for certain of our fixed-rate tax-exempt bonds, through the end of a term interest rate period that exceeds 12 months. The fair value of our fixed-rate debt obligations can increase or decrease significantly if market interest rates change.

We performed a sensitivity analysis to determine how market rate changes might affect the fair value of our market risk-sensitive debt instruments. This analysis is inherently limited because it reflects a singular, hypothetical set of assumptions. Actual market movements may vary significantly from our assumptions. An instantaneous, 100-basis point increase in interest rates across all maturities attributable to these instruments would have decreased the fair value of our debt by approximately $0.8 billion as of December 31, 2025.

We are also exposed to interest rate market risk from our cash and cash equivalent balances, as well as assets held in restricted trust fund accounts. These assets are generally invested in high-quality, liquid instruments including money market funds that invest in U.S. government obligations with original maturities of three months or less. We believe that our exposure to changes in fair value of these assets due to interest rate fluctuations is insignificant as the fair value generally approximates our cost basis. We also invest a portion of our restricted trust fund account balances in available-for-sale securities, including U.S. Treasury securities, U.S. agency securities, municipal securities, mortgage- and asset-backed securities, which generally mature over the next ten years, as well as equity securities.

*Commodity Price Exposure —* In the normal course of our business, we are subject to operating agreements that expose us to market risks arising from changes in the prices for commodities such as diesel fuel, natural gas, electricity (and related renewable energy credits) and recycled materials, including old corrugated cardboard and plastics. We work to manage these risks through operational strategies that focus on capturing our costs in the prices we charge our customers for the services provided. Accordingly, as the market prices for these commodities increase or decrease, our revenues, operating costs and margins may also increase or decrease. Recycling revenues attributable to yield decreased $166 million and increased $245 million in 2025 and 2024, respectively, as compared to prior year periods. During 2025, we experienced decreases in market prices for recycled commodities when compared to prior year caused by a number of factors, including the closure of domestic paper mills, a decrease in demand for recycled content by certain consumer goods producers, focused reduction in cardboard packaging and overall market conditions. Average market prices for single-stream recycled commodities were down 20% and up 50% in 2025 and 2024, respectively, as compared to prior year periods. Variability in commodity prices can also impact the margins of our business as certain components of our revenue are structured as a pass through of costs, including recycling brokerage and fuel surcharges.

In recent years, we have discussed our sustainability growth strategy that includes significant planned and ongoing investments in our Renewable Energy segment. We have invested, and continue to invest, in facilities to capture methane produced from the Company's landfills and process it into RNG and electricity. RNG produced from our landfills constitutes a significant source of fuel allocated to our natural gas collection vehicles. The primary drivers of renewable fuel development at our landfills are tax policies, such as federal tax credits for investments in RNG under the IRA and OBBBA, and federal and state incentive programs, such as the federal RFS program, California's Low Carbon Fuel

[**Table of Contents**](#TOC)

Standard and similar state programs that promote the production and use of renewable transportation fuels. At the federal level, oil refiners and importers are required through the RFS program to blend specified volumes of various categories of renewable transportation fuels with gasoline or buy credits, referred to as RINs, from renewable fuel producers. Many of our facilities are EPA-registered producers of transportation fuel making compressed and liquefied RNG from landfill biogas, which qualifies as a cellulosic biofuel under the RFS program. The Company has invested, and continues to invest, in facilities that capture and process landfill gas into RNG so that we can participate in the RFS program, and the Company has grown and stated its intention to continue to grow its asset base to increase its RNG production.

RINs prices generally respond to regulations enacted by the EPA, as well as fluctuations in supply and demand. The value of the RINs is set through a market established by the RFS program, which market has historically been volatile. Prior to 2022, the EPA had promulgated rules on an annual basis establishing refiners' obligations to purchase RNG and other cellulosic biofuels under the RFS program, which introduced a level of uncertainty into the renewable fuels and RINs market. However, in 2023, the EPA issued a highly anticipated rule establishing biofuel blending volumes under the RFS program for compliance years 2023 through 2025. The rule reflected the outsized role of biogas under the program, delivered on many reforms that benefit the solid waste sector, and recognized the continued growth of the market for RNG in vehicle applications. The current U.S. presidential administration, meanwhile, revisited and retroactively lowered the 2024 blending volumes, has proposed to revisit and lower the 2025 standards, has proposed low volumes for compliance years 2026 and 2027 and departed from the previous administration in granting small refinery exemptions from RFS program requirements. We do not yet know how these changes may impact the demand for renewable fuels and the value of RINs. In an effort to mitigate against such risk and stabilize our RNG portfolio, we are pursuing long-term sales transactions in the voluntary market. We continue to advocate for policies that could reduce the potential for volatility in the RINs market and ensure long-term stability for renewable transportation fuels, as changes in the RINs market or the structure of the RFS program can and has impacted the financial performance of our facilities. Such changes could impact or alter our projected future investments, and such investments may not yield the results anticipated. Revenue in our Renewable Energy segment attributable to yield increased $11 million and $26 million in 2025 and 2024, respectively, as compared to prior year periods, primarily driven by the fluctuations in energy and RIN market prices.

The Company's sustainability growth strategy also is informed by the increased adoption of state and Canadian clean fuel standard programs, utility policies, and voluntary market demand for RNG in transportation and industrial applications. Clean fuel standard programs, originally developed in California and subsequently adopted in Oregon, Washington, and New Mexico, establish annual carbon intensity benchmarks for transportation fuels that decrease over time. A similar program has been adopted in Canada under the Clean Fuel Regulations. These programs operate similar to the RFS program in that certain regulated parties purchase credits from fuel producers, including RNG producers, to meet their carbon intensity obligations. Like RINs, clean fuel standard program credit values can fluctuate with policy and market dynamics. As such, we are advocating for existing programs to adopt measures to promote stability in credit pricing and for other states to adopt similar programs that incentivize the growth in RNG. We also are working closely with stakeholders to encourage the voluntary market for RNG demand, including utility RNG procurement programs, and sustainability protocols, as companies and other customers increasingly look to reduce their GHG emissions profiles. However, these state and voluntary programs may be altered, paused, or otherwise revoked by the applicable governmental authorities or as result of legal challenges.

*Currency Rate Exposure —* Our operations are primarily in the U.S. but we also have significant operations in Canada and certain countries in Europe. Additionally, we have certain support functions in India. Where significant, we have quantified and described the impact of foreign currency translation on components of income, including operating revenues and operating expenses. However, the impact of foreign currency has not materially affected our results of operations.

**REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

To the Stockholders and the Board of Directors of Waste Management, Inc.

**Opinion on Internal Control Over Financial Reporting**

We have audited Waste Management, Inc.'s internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Waste Management, Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the 2025 consolidated financial statements of the Company, and our report dated February 9, 2026 expressed an unqualified opinion thereon.

**Basis for Opinion** 

The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management's Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

**Definition and Limitations of Internal Control Over Financial Reporting** 

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

**REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

To the Stockholders and the Board of Directors of Waste Management, Inc.

**Opinion on the Financial Statements**

We have audited the accompanying consolidated balance sheets of Waste Management, Inc. (the Company) as of December 31, 2025 and 2024, the related consolidated statements of operations, comprehensive income, cash flows and changes in equity for each of the three years in the period ended December 31, 2025, and the related notes (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated February 9, 2026 expressed an unqualified opinion thereon.

**Basis for Opinion**

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

|  | &nbsp;&nbsp;***Landfill Depletion Expense***<br>|
| &nbsp;&nbsp;*Description of the Matter* | &nbsp;&nbsp;At December 31, 2025, the Company's landfill assets, net of accumulated depletion, totaled $8.2 billion and the associated depletion expense for 2025 was $898 million. As discussed in Note 2 of the consolidated financial statements, the Company updates the estimates used to calculate individual landfill depletion rates at least annually, or more often if significant facts change. Landfill depletion rates are used in the computation of landfill depletion expense.<br>Auditing landfill depletion rates and related depletion expense is complex due to the highly judgmental nature of assumptions used in estimating the rates. Significant assumptions used in the calculation of the rates include: estimated future development costs associated with the construction and retirement of the landfill, estimated remaining permitted and expansion airspace, and airspace utilization factors.<br>|
| &nbsp;&nbsp;*How We Addressed the Matter in Our Audit* | &nbsp;&nbsp;We obtained an understanding, evaluated the design, and tested the operating effectiveness of the Company's controls over determining landfill depletion rates and calculating depletion expense. Our audit procedures included, among others, testing controls over: the Company's process for evaluating and updating the significant assumptions used in the development of the landfill depletion rates, management's review of those significant assumptions, and the mathematical accuracy of the calculation and recording of depletion expense. <br>To test the landfill depletion rates, our audit procedures included, among others, assessing methodologies used by the Company and testing the significant assumptions discussed above, inclusive of the underlying data used by the Company in its development of these assumptions. We compared the significant assumptions used by management to historical trends and, when available, to comparably sized landfills accepting a similar type of waste. Regarding expansion airspace, we evaluated the Company's criteria for inclusion of unpermitted expansions in remaining airspace and the application of that criteria to relevant facts. In addition, we considered the professional qualifications and objectivity of management's internal engineers responsible for developing the assumptions. We involved EY engineering specialists to assist with the evaluation of the Company's landfill future development cost and airspace assumptions. We also tested the completeness and accuracy of the historical data utilized in the development of the landfill depletion rates. |

|  | &nbsp;&nbsp;***Landfill – Final Capping, Closure and Post-Closure Costs*** |
| &nbsp;&nbsp;*Description of the Matter* | &nbsp;&nbsp;At December 31, 2025, the Company's landfill asset retirement obligations related to final capping, closure and post-closure costs totaled $3.3 billion. As discussed in Note 2 of the consolidated financial statements, the Company updates the estimates used to measure the asset retirement obligations annually, or more often if significant facts change.<br>Auditing the landfill asset retirement obligation is complex due to the highly judgmental nature of the assumptions used in the measurement process. Significant assumptions include: estimated future costs associated with the capping, closure and post-closure activities at each landfill, airspace consumed to date in relation to total estimated permitted and expansion airspace and the projected remaining landfill life.<br>|
| &nbsp;&nbsp;*How We Addressed the Matter in Our Audit* | &nbsp;&nbsp;We obtained an understanding, evaluated the design, and tested the operating effectiveness of the Company's controls over the calculation of landfill asset retirement obligations. Our audit procedures included, among others, testing the Company's controls over the landfill asset retirement obligation estimation process and management's review of the significant assumptions used in the estimation of the liability, including the amount and timing of retirement costs.<br>To test the landfill asset retirement obligation, we performed audit procedures that included, among others, assessing methodologies used by the Company, testing the completeness of activities included in the estimate (e.g., gas monitoring and extraction), and testing the significant assumptions discussed above, inclusive of the underlying data used by the Company in its development of these assumptions. We compared the significant assumptions used by management to historical trends and, when available, to comparably sized landfills accepting the same type of waste. In addition, we considered the professional qualifications and objectivity of management's internal engineers responsible for developing the assumptions. We involved EY engineering specialists to assist us in evaluating the reasons for significant changes in assumptions from the historical trend and determining whether the change from the historical trend was appropriate and identified timely. We also tested the completeness and accuracy of the historical data utilized in preparing the estimate.<br>|
|  | &nbsp;&nbsp;***Goodwill Impairment Assessment - Healthcare Solutions Segment*** |
| &nbsp;&nbsp;*Description of the Matter* | &nbsp;&nbsp;At December 31, 2025, the Company's goodwill related to the Healthcare Solutions segment totaled $3.8 billion. As discussed in Note 2 and Note 5 of the consolidated financial statements, goodwill is tested for impairment at least annually on October 1 at the reporting unit level, or more frequently if impairment indicators arise. The assessment of goodwill for impairment requires a comparison of the fair value of the reporting unit to its carrying amount, including goodwill. If the fair value of a reporting unit is less than its carrying amount, an impairment loss would be recognized. <br>Auditing the Company's annual goodwill impairment test for one Healthcare Solutions reporting unit was complex due to the significant estimation uncertainty in determining the fair value of the reporting unit. The significant estimation uncertainty was primarily due to the sensitivity of the fair value to underlying assumptions used in the income approach, including EBITDA margin and discount rate. These significant assumptions could be impacted by future economic and market conditions.<br>|
| &nbsp;&nbsp;*How We Addressed the Matter in Our Audit* | &nbsp;&nbsp;We obtained an understanding, evaluated the design, and tested the operating effectiveness of the Company's controls over the goodwill impairment process. We tested management's review controls over the significant assumptions described above. |

---

[**Table of Contents**](#TOC)

&nbsp;&nbsp;To test the estimated fair value of the Healthcare Solutions reporting unit, our audit procedures included, among others, evaluating the Company's selection of the valuation methodology, evaluating the significant assumptions described above used to develop the prospective financial information and testing the completeness and accuracy of the underlying data supporting the significant assumptions. We involved our valuation specialists to assist with evaluating the methodology and significant assumptions used by management to determine the fair value estimate. We compared the significant assumptions used by the Company to relevant industry reports, historical operating results and other guideline companies within the same industry. We also performed sensitivity analyses of the significant assumptions to evaluate the changes in the fair value of the reporting unit that would result from changes in the assumptions.<br>

#### WASTE MANAGEMENT, INC.

#### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
**Years Ended December 31, 2025, 2024 and 2023**

**1.&nbsp;&nbsp;&nbsp;&nbsp;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 18. 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, recycling and resource recovery services. Through our Waste Management Renewable Energy ("Renewable Energy") segment, 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 ("RNG"), which is a significant source of fuel that we allocate to our natural gas fleet. Following our 2024 acquisition of Stericycle, Inc. ("Stericycle"), our Healthcare Solutions segment provides regulated waste and compliance services ("RWCS") and secure information destruction ("SID") services in the U.S., Canada and Western Europe that protect people and brands, promote health and well-being and safeguard the environment. Additionally, through our Recycling Processing and Sales segment, we are a leading recycler in the U.S. and Canada, handling materials that include paper, cardboard, glass, plastic and metal.

Our senior management evaluates, oversees and manages the financial performance of our business through five reportable segments, referred to as (i) Collection and Disposal - East Tier ("East Tier"); (ii) Collection and Disposal - West Tier ("West Tier"); (iii) Recycling Processing and Sales; (iv) Renewable Energy and (v) Healthcare Solutions. Our East and West Tiers, along with certain ancillary services ("Other Ancillary") that are not managed through our Tier segments but that support our collection and disposal operations, form our "Collection and Disposal" businesses. We also provide additional services not managed through our five reportable segments, which are presented as Corporate and Other. Refer to Note 19 for further discussion.

#### Reclassifications
When necessary, reclassifications have been made to our prior period financial information to conform to the current year presentation and are not material to our consolidated financial statements.

2.&nbsp;&nbsp;&nbsp;&nbsp;Summary of Significant Accounting Policies

#### Principles of Consolidation
The accompanying Consolidated Financial Statements include the accounts of WMI, its wholly-owned and majority-owned subsidiaries and certain variable interest entities for which we have determined that we are the primary beneficiary. In the opinion of management, these Consolidated 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. All material intercompany balances and transactions have been eliminated. Investments in unconsolidated entities are accounted for under the appropriate method of accounting.

#### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

#### Estimates and Assumptions
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. Each of these items is discussed in additional detail below. Actual results could differ materially from the estimates and assumptions that we use in the preparation of our financial statements.

#### Cash and Cash Equivalents
Cash in excess of current operating requirements is invested in short-term interest-bearing instruments with maturities of three months or less at the date of purchase and is stated at cost, which approximates market value.

#### 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 and other receivables. 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. As of December 31, 2025 and 2024, no single customer represented greater than 5% of total accounts receivable.

#### Accounts and Other Receivables
Our receivables, which are recorded when billed, when services are performed or when cash is advanced, are claims against third parties that will generally be settled in cash. The carrying value of our receivables, net of the allowance for doubtful accounts, represents the estimated net realizable value. We estimate our allowance for doubtful accounts based on historical collection trends; type of customer, such as municipal or commercial; the age of outstanding receivables as well as existing and expected economic conditions. If events or changes in circumstances indicate that specific receivable balances may be impaired, further consideration is given to the collectability of those balances and the allowance is adjusted accordingly. Past-due receivable balances are written off when our collection efforts have been unsuccessful. Also, we recognize interest income on long-term interest-bearing notes receivable as the interest accrues under the terms of the notes. We no longer accrue interest once the notes are deemed uncollectible.

[**Table of Contents**](#TOC)

#### WASTE MANAGEMENT, INC.

#### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
The following table reflects the activity in our allowance for doubtful accounts of trade receivables for the year ended December 31 (in millions):

---

| | | |
|:---|:---|:---|
|  | **2025** | **2024** |
| Balance as of January 1 | $165 | $30 |
| &nbsp;&nbsp;Additions charged to expense | 85 | 65 |
| &nbsp;&nbsp;Accounts written-off, net of recoveries | (171) | (55) |
| &nbsp;&nbsp;Acquisitions, divestitures and other, net | 8 | 125 |
| Balance as of December 31 | $87 | $165 |

---

To determine the allowance for doubtful accounts for trade receivables, we rely upon, among other factors, historical payment and loss trends, the age of outstanding receivables, as well as existing and expected economic conditions. We believe that trade receivables across our Collection and Disposal, Recycling Processing and Sales, and Renewable Energy segments share similar risk characteristics. We monitor our credit exposure on an ongoing basis and assess whether trade receivables continue to display similar risk characteristics.

Generally, the risk characteristics of Healthcare Solutions customers are similar to customers of our other business segments, though complexities within the customer engagement systems and processes of the acquired business have caused billing and collection delays. As of the acquisition date, the Company determined that these issues contributed to a portion of the acquired Stericycle receivables having a more-than-insignificant deterioration in credit quality since origination. As a result, a gross allowance for doubtful accounts of trade receivables was established with our opening balance sheet for the acquired business in the amount of $144 million. Over the course of 2025, $88 million of acquired and reserved trade account receivable balances related to the Stericycle acquisition was written off.

Based on aging analysis as of December 31, 2025 and 2024, approximately 85% of our trade receivables were outstanding less than 60 days.

To determine the allowance for doubtful accounts for other receivables, as well as loans and other instruments, we rely primarily on credit ratings and associated default rates based on the maturity of the instrument. Other receivables, as of December 31, 2025 and 2024, include receivables related to income tax payments in excess of our current income tax obligations of $482 million and $255 million, respectively. Other receivables as of December 31, 2025 and 2024 also include a receivable of $25 million and $46 million, respectively, related to alternative fuel tax credits. Based on an aging analysis as of December 31, 2025 and 2024, approximately 70% and 65%, respectively, of our other receivables were due within 12 months or less.

#### Parts and Supplies
Parts and supplies consist primarily of spare parts, fuel, tires, lubricants and processed recycling materials. Our parts and supplies are stated at the lower of cost (using the average cost method) or market.

#### Landfill Accounting
*Cost Basis of Landfill Assets —* We capitalize various costs that we incur to make a landfill ready to accept waste. These costs generally include expenditures for land (including the landfill footprint and required landfill buffer property); permitting; excavation; liner material and installation; landfill leachate collection systems; landfill gas collection systems; environmental monitoring equipment for groundwater and landfill gas; and directly related engineering, capitalized interest, on-site road construction and other capital infrastructure costs. The cost basis of our landfill assets also includes asset retirement costs, which represent estimates of future costs associated with landfill final capping, closure and post-closure activities. These costs are discussed below.

[**Table of Contents**](#TOC)

#### WASTE MANAGEMENT, INC.

#### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
*Final Capping, Closure and Post-Closure Costs —* Following is a description of our asset retirement activities and our related accounting:

● *Final Capping —* Generally involves the installation of flexible membrane liners and geosynthetic clay liners, drainage and compacted soil layers and topsoil over areas of a landfill where total airspace has been consumed. Final capping asset retirement obligations are recorded on a units-of-consumption basis as airspace is consumed related to the specific final capping event with a corresponding increase in the landfill asset. Each final capping event is accounted for as a discrete obligation and recorded as an asset and a liability based on estimates of the discounted cash flows associated with each final capping event.

● *Closure —* Includes the construction of the final portion of methane gas collection systems (when required), demobilization and routine maintenance costs. These are costs incurred after the site ceases to accept waste, but before the landfill is certified as closed by the applicable regulatory agency. These costs are recorded as an asset retirement obligation as airspace is consumed over the life of the landfill with a corresponding increase in the landfill asset. Closure obligations are recorded over the life of the landfill based on estimates of the discounted cash flows associated with performing closure activities.

● *Post-Closure —* Involves the maintenance and monitoring of a landfill site that has been certified closed by the applicable regulatory agency. Generally, we are required to maintain and monitor landfill sites for a 30-year period. These maintenance and monitoring costs are recorded as an asset retirement obligation as airspace is consumed over the life of the landfill with a corresponding increase in the landfill asset. Post-closure obligations are recorded over the life of the landfill based on estimates of the discounted cash flows associated with performing post-closure activities.

We develop our estimates of these obligations using input from our operations personnel, engineers and accountants. Our estimates are based on our interpretation of current requirements and are intended to approximate fair value. Absent quoted market prices, the estimate of fair value is based on the best available information, including the results of present value techniques. In many cases, we contract with third parties to fulfill our obligations for final capping, closure and post-closure. We use historical experience, professional engineering judgment and quoted or actual prices paid for similar work to determine the fair value of these obligations. We are required to recognize these obligations at market prices whether we plan to contract with third parties or perform the work ourselves. In those instances where we perform the work with internal resources, the incremental profit margin realized is recognized as a component of operating income when the work is completed.

Once we have determined final capping, closure and post-closure costs, we inflate those costs to the expected time of payment and discount those expected future costs back to present value. As of December 31, 2025, 2024 and 2023, we inflated these costs in current dollars to the expected time of payment using an inflation rate of 2.50%, for each year. We discounted these costs to present value using the credit-adjusted, risk-free rate effective at the time an obligation is incurred, consistent with the expected cash flow approach. Any changes in expectations that result in an upward revision to the estimated cash flows are treated as a new liability and discounted at the current rate while downward revisions are discounted at the historical weighted average rate of the recorded obligation. As a result, the credit-adjusted, risk-free discount rate used to calculate the present value of an obligation is specific to each individual asset retirement obligation. The weighted average rate applicable to our long-term asset retirement obligations as of December 31, 2025 was approximately 4.9%.

We record the estimated fair value of final capping, closure and post-closure liabilities for our landfills based on the airspace consumed through the current period. The fair value of final capping obligations is developed based on our estimates of the airspace consumed to date for each final capping event and the expected timing of each final capping event. The fair value of closure and post-closure obligations is developed based on our estimates of the airspace consumed to date for the entire landfill and the expected timing of each closure and post-closure activity. Because these obligations

[**Table of Contents**](#TOC)

#### WASTE MANAGEMENT, INC.

#### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
are measured at estimated fair value using present value techniques, changes in the estimated cost or timing of future final capping, closure and post-closure activities could result in a material change in these liabilities, related assets and results of operations. We assess the appropriateness of the estimates used to develop our recorded balances annually, or more often if significant facts change.

Sustained changes in inflation rates or the estimated costs, timing or extent of future final capping, closure and post-closure activities typically result in both (i) a current adjustment to the recorded liability and landfill asset and (ii) a change in liability and asset amounts to be recorded prospectively over either the remaining permitted and expansion airspace (as defined below) of the related discrete final capping event or the remaining permitted and expansion airspace of the landfill, as appropriate. Any changes related to the capitalized and future cost of the landfill assets are then recognized in accordance with our landfill depletion policy, which would generally result in depletion expense being recognized prospectively over the remaining permitted and expansion airspace of the final capping event or the remaining permitted and expansion airspace of the landfill, as appropriate. Changes in such estimates associated with a fully consumed landfill result in an adjustment to the recorded liability and landfill assets with an immediate corresponding adjustment to landfill airspace depletion expense.

Interest accretion on final capping, closure and post-closure liabilities is recorded using the effective interest method and is recorded as landfill operating costs, which is included in operating expenses within our Consolidated Statements of Operations.

*Depletion of Landfill Assets —* The depletable basis of a landfill includes (i) amounts previously expended and capitalized, net of accumulated airspace depletion; (ii) capitalized landfill final capping, closure and post-closure costs, net of accumulated airspace depletion; (iii) projections of future purchase and development costs required to develop the landfill site to its remaining permitted and expansion airspace (as defined below) and (iv) projected asset retirement costs related to landfill final capping, closure and post-closure activities.

Depletion is recorded on a units-of-consumption basis, applying expense as a rate per ton. The rate per ton is calculated by dividing each component of the depletable basis of a landfill by the number of tons needed to fill the corresponding asset's airspace. For landfills that we do not own, but operate through lease or other contractual agreements, the rate per ton is calculated based on expected airspace to be utilized over the lesser of the contractual term of the underlying agreement or the life of the landfill.

We apply the following guidelines in determining a landfill's remaining permitted and expansion airspace:

● *Remaining Permitted Airspace —* Our engineers, in consultation with third-party engineering consultants and surveyors, are responsible for determining remaining permitted airspace at our landfills. The remaining permitted airspace is determined by an annual survey, which is used to compare the existing landfill topography to the expected final landfill topography.

● *Expansion Airspace —* We also include currently unpermitted expansion airspace in our estimate of remaining permitted and expansion airspace in certain circumstances. First, for unpermitted airspace to be initially included in our estimate of remaining permitted and expansion airspace, we must believe that obtaining the expansion permit is likely. Second, we must generally expect the initial expansion permit application to be submitted within one year and the final expansion permit to be received within five years, in addition to meeting the following criteria:

● Personnel are actively working on the expansion of an existing landfill, including efforts to obtain land use and local, state or provincial approvals;

● We have a legal right to use or obtain land to be included in the expansion plan;

[**Table of Contents**](#TOC)

#### WASTE MANAGEMENT, INC.

#### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
● There are no significant known technical, legal, community, business, or political restrictions or similar issues that could negatively affect the success of such expansion; and

● Financial analysis has been completed based on conceptual design, and the results demonstrate that the expansion meets Company criteria for investment.

These criteria are evaluated by our field-based engineers, accountants, managers and others to identify potential obstacles to obtaining the permits. Once the unpermitted airspace is included, our policy provides that airspace may continue to be included in remaining permitted and expansion airspace even if certain of these criteria are no longer met as long as we continue to believe we will ultimately obtain the permit, based on the facts and circumstances of a specific landfill. In these circumstances, continued inclusion must be approved through a landfill-specific review process that includes approval by our Chief Financial Officer on a quarterly basis. Of the 15 landfill sites with expansions included as of December 31, 2025, there were none that required approval by our Chief Financial Officer.

When we include the expansion airspace in our calculations of remaining permitted and expansion airspace, we also include the projected costs for development, as well as the projected asset retirement costs related to final capping, closure and post-closure of the expansion in the depletable basis of the landfill.

Once the remaining permitted and expansion airspace is determined in cubic yards, an airspace utilization factor ("AUF") is established to calculate the remaining permitted and expansion capacity in tons. The AUF is established using the measured density obtained from previous annual surveys and is then adjusted to account for future settlement. The amount of settlement that is forecasted will consider several site-specific factors including current and projected mix of waste type, initial and projected waste density, estimated number of years of life remaining, depth of underlying waste, anticipated access to moisture through precipitation or recirculation of landfill leachate and operating practices. In addition, the initial selection of the AUF is subject to a subsequent multi-level review by our engineering group and the AUF used is reviewed on a periodic basis and revised as necessary. Our historical experience generally indicates that the impact of settlement at a landfill is greater later in the life of the landfill when the waste placed at the landfill approaches its highest point under the permit requirements.

After determining the costs and remaining permitted and expansion capacity at each of our landfills, we determine the per ton rates that will be expensed as waste is received and deposited at the landfill by dividing the costs by the corresponding number of tons. We calculate per ton depletion rates for each landfill for assets associated with each final capping event, for assets related to closure and post-closure activities and for all other costs capitalized or to be capitalized in the future. These rates per ton are updated annually, or more often, as significant facts change.

It is possible that actual results, including the amount of costs incurred, the timing of final capping, closure and post-closure activities, our airspace utilization or the success of our expansion efforts could ultimately turn out to be significantly different from our estimates and assumptions. To the extent that such estimates, or related assumptions, prove to be significantly different than actual results, lower earnings may be experienced due to higher depletion rates or higher expenses; or higher earnings may result if the opposite occurs. Most significantly, if it is determined that expansion capacity should no longer be considered in calculating the recoverability of a landfill asset, we may be required to recognize an asset impairment or incur significantly higher depletion expense. If at any time management makes the decision to abandon the expansion effort, the capitalized costs related to the expansion effort are expensed immediately.

#### Environmental Remediation Liabilities
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

[**Table of Contents**](#TOC)

#### WASTE MANAGEMENT, INC.

#### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
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.

Where it is probable that a liability has been incurred, we estimate costs required to remediate sites based on site-specific facts and circumstances. We routinely review and evaluate sites that require remediation and determine our estimated cost for the likely remedy based on a number of estimates and assumptions. Next, we review the same type of information with respect to other named and unnamed PRPs. Estimates of the costs for the likely remedy are then developed using our internal resources, third-party environmental engineers or other service providers. Internally developed estimates are based on:

● Management's judgment and experience in remediating our own and unrelated parties' sites;

● Information available from regulatory agencies as to costs of remediation;

● The number, financial resources and relative degree of responsibility of other PRPs who may be liable for remediation of a specific site; and

● The typical allocation of costs among PRPs, unless the actual allocation has been determined.

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 (where estimable), our aggregate potential liability would be approximately $8 million higher than the $231 million recorded in the Consolidated Balance Sheet as of December 31, 2025. 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.

We record our obligations on an undiscounted basis unless we are aware of a material environmental liability where we believe that both the amount and timing of the payments are fixed or reliably determinable.

#### Property and Equipment (exclusive of landfills, discussed above)
We record property and equipment at cost. Expenditures for major additions and improvements are capitalized and maintenance activities are expensed as incurred. We depreciate property and equipment over the estimated useful life of the asset using the straight-line method. We generally assume no salvage value for our depreciable property and equipment. When property and equipment are retired, sold or otherwise disposed of, the cost and accumulated depreciation are removed from our accounts and any resulting gain or loss is included in results of operations as an offset or increase to operating expense for the period.

#### Leases
We lease property and equipment in the ordinary course of our business. Our operating lease activities primarily consist of leases for real estate, landfills, fleet vehicles and operating equipment. Our financing lease activities primarily consist of leases for operating equipment, railcars and landfill assets. Our leases have varying terms. Some may include renewal or purchase options, escalation clauses, restrictions, penalties or other obligations that we consider in determining minimum lease payments. The leases are classified as either operating leases or financing leases, as appropriate.

*Operating Leases (excluding landfill leases discussed below) —* The majority of our leases are operating leases. This classification generally can be attributed to either (i) relatively low fixed minimum lease payments as a result of real property lease obligations that vary based on the volume of waste we receive or process or (ii) minimum lease terms that are much shorter than the assets' economic useful lives. Management expects that in the normal course of business our operating leases will be renewed, replaced by other leases or replaced with fixed asset expenditures.

*Financing Leases (excluding landfill leases discussed below) —* Assets under financing leases are capitalized using interest rates determined at the commencement of each lease and are depreciated over either the useful life of the asset or the lease term, as appropriate, on a straight-line basis. The present value of the related lease payments is recorded as a debt obligation.

*Landfill Leases —* From an operating perspective, landfills that we lease are similar to landfills we own because generally we will operate the landfill for the life of the operating permit. The most significant portion of our rental obligations for landfill leases is contingent upon operating factors such as disposal volume and often there are no contractual minimum rental obligations. Contingent rental obligations are expensed as incurred. For landfill financing leases that provide for minimum contractual rental obligations, we record the present value of the minimum obligation as part of the landfill asset, which is depleted on a units-of-consumption basis over the shorter of the lease term or the life of the landfill.

For operating and financing leases, including landfill leases, our rent expense for each of the last three years and future minimum lease payments are disclosed in Note 7.

#### Acquisitions
We generally recognize assets acquired and liabilities assumed in business combinations, including contingent assets and liabilities, based on fair value estimates as of the date of acquisition.

*Contingent Consideration —* In certain acquisitions, we agree to pay additional amounts to sellers contingent upon achievement by the acquired businesses of certain negotiated goals, such as targeted revenue levels, targeted disposal volumes or the issuance of permits for expanded landfill airspace. We have recognized liabilities for these contingent

[**Table of Contents**](#TOC)

#### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
obligations based on their estimated fair value as of the date of acquisition with any differences between the acquisition date fair value, subsequent remeasurements and the ultimate settlement of the obligations being recognized as an adjustment to income from operations. Refer to Note 11 for adjustments recognized during the reported periods.

*Acquired Assets and Assumed Liabilities —* Assets and liabilities arising from contingencies such as pre-acquisition environmental matters and litigation are recognized at their acquisition-date fair value when their respective fair values can be determined. Acquired contingencies whose fair value is not determinable during the measurement period are recognized only if they are probable and reasonably estimable.

Acquisition-date fair value estimates are revised as necessary if, and when, additional information regarding these contingencies becomes available to further define and quantify assets acquired and liabilities assumed. Subsequent to finalization of purchase accounting, these revisions are accounted for as adjustments to income from operations. All acquisition-related transaction costs are generally expensed as incurred. See Note 17 for additional information related to our acquisitions.

#### Goodwill and Other Intangible Assets
Goodwill is the excess of our purchase cost over the fair value of the net assets of acquired businesses. As discussed in the *Long-Lived Asset Impairments* section below, we assess our goodwill for impairment at least annually.

Other intangible assets consist primarily of customer and supplier relationships, covenants not-to-compete, licenses, permits (other than landfill permits, which are combined with landfill tangible assets and depleted per our landfill depletion policy), trade names and other contracts. Other intangible assets are recorded at fair value on the acquisition date and are generally amortized using either a 150% declining balance approach or a straight-line basis as we determine appropriate. Customer and supplier relationships are typically amortized over terms of 10 to 15 years. Covenants not-to-compete are amortized over the term of the non-compete covenant, which is generally five years. Definite-lived intangibles are amortized over their useful lives on a straight-line basis while indefinite-lived intangibles are not amortized. Licenses, permits and other contracts are amortized over the definitive terms of the related agreements. If the underlying agreement does not contain definitive terms and the useful life is determined to be indefinite, the asset is not amortized.

#### Long-Lived Asset Impairments
We assess our long-lived assets for impairment as required under the applicable accounting standards. If necessary, impairments are recorded in (gain) loss from divestitures, asset impairments and unusual items, net in our Consolidated Statements of Operations.

*Property and Equipment, Including Landfills and Definite-Lived Intangible Assets* — We monitor the carrying value of our long-lived assets for potential impairment on an ongoing basis and test the recoverability of such assets generally using significant unobservable ("Level 3") inputs whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. These events or changes in circumstances, including management decisions pertaining to such assets, are referred to as impairment indicators. If an impairment indicator occurs, we perform a test of recoverability by comparing the carrying value of the asset or asset group to its undiscounted expected future cash flows. If cash flows cannot be separately and independently identified for a single asset, we will determine whether an impairment has occurred for the group of assets for which we can identify the projected cash flows. If the carrying values are in excess of undiscounted expected future cash flows, we measure any impairment by comparing the fair value of the asset or asset group to its carrying value and the difference is recorded in the period that the impairment indicator occurs. Fair value is generally determined by considering (i) internally developed discounted projected cash flow analysis of the asset or asset group; (ii) third-party valuations and/or (iii) information available regarding the current market for similar assets.

[**Table of Contents**](#TOC)

#### WASTE MANAGEMENT, INC.

#### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
Estimating future cash flows requires significant judgment and projections may vary from the cash flows eventually realized, which could impact our ability to accurately assess whether an asset has been impaired.

The assessment of impairment indicators and the recoverability of our capitalized costs associated with landfills and related expansion projects require significant judgment due to the unique nature of the waste industry, the highly regulated permitting process and the sensitive estimates involved. During the review of a landfill expansion application, a regulator may initially deny the expansion application although the expansion permit is ultimately granted. In addition, management may periodically divert waste from one landfill to another to conserve remaining permitted landfill airspace, or a landfill may be required to cease accepting waste, prior to receipt of the expansion permit. However, such events occur in the ordinary course of business in the waste industry and do not necessarily result in impairment of our landfill assets because, after consideration of all facts, such events may not affect our belief that we will ultimately obtain the expansion permit. As a result, our tests of recoverability, which generally make use of a probability-weighted cash flow estimation approach, may indicate that no impairment loss should be recorded.

*Indefinite-Lived Intangible Assets, Including Goodwill —* At least annually using a measurement date of October 1, and more frequently if warranted, we assess our indefinite-lived intangible assets, including the goodwill of our reporting units, for impairment.

We may perform either a qualitative or quantitative assessment; however, if a qualitative assessment is performed and we determine that the fair value of a reporting unit is more likely than not to be less than its carrying amount, a quantitative assessment is performed. The quantitative assessment compares the estimated fair value of a reporting unit to its carrying amount, including goodwill. An impairment charge is recognized if the reporting unit's estimated fair value is less than its carrying amount. Fair value is typically estimated using an income approach using Level 3 inputs. However, when appropriate, we may also use a market approach. The income approach is based on the long-term projected future cash flows of the reporting units. We discount the estimated cash flows to present value using a weighted average cost of capital that considers factors such as market assumptions, the timing of the cash flows and the risks inherent in those cash flows. We believe that this approach is appropriate because it provides a fair value estimate based upon the reporting units' expected long-term performance considering the economic and market conditions that generally affect our business. The market approach estimates fair value by measuring the aggregate market value of publicly-traded companies with similar characteristics to our business as a multiple of their reported earnings. We then apply that multiple to the reporting units' earnings to estimate their fair values. We believe that this approach may also be appropriate in certain circumstances because it provides a fair value estimate using valuation inputs from entities with operations and economic characteristics comparable to our reporting units.

Fair value is computed using several factors, including projected future operating results, economic projections, anticipated future cash flows, comparable marketplace data and the cost of capital. There are inherent uncertainties related to these factors and to our judgment in applying them in our analysis. However, we believe our methodology for estimating the fair value of our reporting units is reasonable.

As part of our 2025 annual assessment, we performed a quantitative review for a reporting unit within our Healthcare Solutions segment due its sensitivity to changes in estimates of fair value, specifically changes driven by revenue growth, cost and discount rate assumptions, given the recent acquisition of the business. Based on our assessment no impairment was recorded for the year ended December 31, 2025. Refer to Note 11 for information related to impairments recognized during the reported periods.

#### Insured and Self-Insured Claims
We have retained a significant portion of the risks related to our health and welfare, general liability, automobile liability and workers' compensation claims programs. For our self-insured portions, the exposure for unpaid claims and

[**Table of Contents**](#TOC)

#### WASTE MANAGEMENT, INC.

#### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
associated expenses, including incurred but not reported losses, is based on an actuarial valuation or internal estimates. The gross estimated liability associated with settling unpaid claims is included in accrued liabilities in our Consolidated Balance Sheets if expected to be settled within one year; otherwise, it is included in other long-term liabilities. Estimated insurance recoveries related to recorded liabilities are reflected as other current receivables or other long-term assets in our Consolidated Balance Sheets when we believe that the receipt of such amounts is probable.

We use a wholly-owned insurance captive to insure the deductibles for our general liability, automobile liability and workers' compensation claims programs. We continue to maintain conventional insurance policies with third-party insurers. WMI pays an annual premium to the insurance captive on behalf of WMI and its insured subsidiaries, typically in the first quarter of the year, for estimated losses based on an external actuarial analysis. These premiums are held in a restricted funds account to be used solely for paying insurance claims, resulting in a transfer of risk from our Company to the insurance captive, and are allocated between current and long-term assets depending on estimated timing of the use of funds.

#### Restricted Funds
Our restricted funds accounts primarily consist of funds deposited for purposes of funding insurance claims and settling landfill final capping, closure, post-closure and environmental remediation obligations. These funds are generally allocated between cash, money market funds, equity securities and available-for-sale debt securities depending on the estimated timing and purpose of the use of funds. We use a wholly-owned insurance captive to insure the deductibles for certain claims programs and the premiums paid are directly deposited into a restricted funds account to be used solely for paying insurance claims. At several of our landfills, we provide financial assurance by depositing cash into restricted trust funds for purposes of settling final capping, closure, post-closure and environmental remediation obligations. Balances maintained in these restricted funds accounts will fluctuate based on (i) changes in statutory requirements; (ii) future deposits made to comply with contractual arrangements; (iii) the ongoing use of funds; (iv) acquisitions or divestitures and (v) changes in the fair value of the financial instruments held in the restricted funds accounts.

See Notes 16 and 18 for additional discussion related to restricted funds accounts for final capping, closure, post-closure or environmental remediation obligations.

#### Investments in Unconsolidated Entities
As a result of adopting Accounting Standards Update ("ASU") 2023-02 in 2024, our investments in entities established to invest in and manage low-income housing properties are accounted for using the proportional amortization method. Under the proportional amortization method, the equity investment is amortized in proportion to the income tax credits and other income tax benefits received. Investments in unconsolidated entities over which the Company has significant influence are accounted for under the equity method of accounting. Equity investments in which the Company does not have the ability to exert significant influence over the investees' operating and financing activities are measured using a quantitative approach as these investments do not have readily determinable fair values. The quantitative approach, or measurement alternative, is equal to its cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. The following table summarizes our investments in unconsolidated entities as of December 31 (in millions):

---

| | | |
|:---|:---|:---|
|  | **2025** | **2024** |
| Equity method investments | $98 | $86 |
| Investments qualifying for proportional amortization method | 624 | 707 |
| Investments without readily determinable fair values | 57 | 53 |
| &nbsp;&nbsp;&nbsp;&nbsp;Investments in unconsolidated entities | $779 | $846 |

---

[**Table of Contents**](#TOC)

#### WASTE MANAGEMENT, INC.

#### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
We monitor and assess the carrying value of our investments throughout the year for potential impairment and write them down to their fair value when other-than-temporary declines exist. Fair value is generally based on (i) other third-party investors' recent or pending transactions in the securities; (ii) other information available regarding the current market for similar assets; (iii) a market or income approach, as deemed appropriate and/or (iv) a quantitative approach, or measurement alternative, as noted above. Impairments of our investments are recorded in (gain) loss from divestitures, asset impairments and unusual items, net in our Consolidated Statements of Operations in accordance with appropriate accounting guidance.

Refer to Note 11 for information related to impairments and other adjustments recognized during the reported periods.

#### Derivative Instruments
At times we use derivative instruments to manage risk. To qualify for hedge accounting, the hedged item must expose us to risk and the related derivative instrument must reduce the exposure to that risk and meet specific hedge documentation requirements related to designation dates, expectations for hedge effectiveness and the probability that hedged future transactions will occur as forecasted. We formally designate derivative instruments as hedges and document and assess their effectiveness at inception of the hedge and on a quarterly basis thereafter. Forecasted transactions are evaluated for the probability of occurrence.

We are required to recognize derivative instruments at fair value as either assets or liabilities on our Consolidated Balance Sheets unless such instruments meet certain normal purchase/normal sale criteria. For derivatives that qualify for hedge accounting, we designate them as cash flow hedges. The change in the fair value of a cash flow hedge is reported in accumulated other comprehensive income (loss) and is reclassified to earnings when the forecasted transaction affects earnings.

#### Foreign Currency
Our operations are primarily in the U.S. but we also have significant operations in Canada and certain countries in Western Europe. Additionally, we have certain support functions in India. Local currencies generally are considered the functional currencies of our operations and investments outside the U.S. The assets and liabilities of our foreign operations are translated to U.S. dollars using the exchange rate as of the balance sheet date. Revenues and expenses are translated to U.S. dollars using the average exchange rate during the period. The resulting translation difference is reflected as a component of other comprehensive income (loss), net of tax. Foreign currency translation adjustments have primarily been impacted by fluctuations in the U.S. dollar/Canadian dollar exchange rate and to a lesser extent, the U.S. dollar/Euro exchange rates and the U.S. dollar/British pound sterling exchange rate.

The U.S. dollar/Canadian dollar exchange rate was 1.3724 at December 31, 2025, 1.4384 at December 31, 2024 and 1.3243 at December 31, 2023. The U.S. dollar/Euro exchange rate was 0.8514 at December 31, 2025 and 0.9659 at December 31, 2024. The U.S. dollar/British pound sterling exchange rate was 0.7421 at December 31, 2025 and 0.7990 at December 31, 2024. Refer to Note 12 for information regarding the impacts of foreign currency on our comprehensive income and results of operations.

#### 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, transfer stations or processing facilities; or recycling and other commodities, such as RNG, electricity and capacity, Renewable Identification Numbers ("RINs") and Renewable Energy Credits ("RECs"), are sold. Compliance services revenues are recognized over the contractual service period. We also bill for certain services prior to performance. Such services include, among others, certain commercial

[**Table of Contents**](#TOC)

#### WASTE MANAGEMENT, INC.

#### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
and residential contracts, and equipment rentals. These advanced billings are included in deferred revenues and recognized as revenue in the period service is provided.

Our Collection and Disposal operating revenues are primarily generated from fees charged for our collection, transfer and disposal. Revenues from our collection operations are influenced by factors such as collection frequency, type of collection equipment furnished, type and volume or weight of the waste collected, distance to the disposal facility or recycling facility and our disposal costs. Revenues from our landfill operations consist of tipping fees, which are generally based on the type and weight or volume of waste being disposed of at our disposal facilities. Fees charged at transfer stations are generally based on the weight or volume of waste deposited, considering our cost of loading, transporting and disposing of the solid waste at a disposal site. The fees we charge for our services generally include applicable fees, such as our energy surcharge, which are intended to pass through to customers direct and indirect costs incurred.

Recycling Processing and Sales revenues generally consist of tipping fees and the sale of recycling commodities to and/or on behalf of third parties.

Our Renewable Energy revenue is primarily generated from (i) the sale of captured and converted landfill methane gas; (ii) the sale of RINs under the Renewable Fuel Standard ("RFS") program implemented by the U.S. Environmental Protection Agency ("EPA"); (iii) sale of Low Carbon Fuel credits designed to stimulate the use of low-carbon fuels and (iv) the sale of energy (electricity and capacity) and associated RECs.

Our Healthcare Solutions revenue is primarily generated from (i) RWCS, which provide collection, processing and disposal of regulated and specialized waste, including medical, pharmaceutical and hazardous waste, and compliance programs and (ii) SID services, which provide for the collection of personal and confidential information for secure destruction and recycling of sorted office paper. The customers typically enter into a contract for the provision of services on a weekly, monthly or as-needed basis over the contract term. We receive fees based on a monthly, quarterly or annual rate and/or fees based on contractual rates depending on measures including the volume, weight, and type of waste, as specified in applicable contracts.

See Note 19 for additional information related to revenue by reportable segment and major lines of business.

*Deferred Revenues*

We record deferred revenues when cash payments are received or due in advance of our performance and classify them as current since they are earned within a year and there are no significant financing components. 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 16 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 Consolidated Balance Sheets.

As of December 31, 2025 and 2024, we had $237 million and $218 million of deferred contract costs, respectively, of which $177 million and $154 million, respectively, were related to deferred sales incentives. During each of the years ended December 31, 2025, 2024 and 2023, we amortized $31 million, $28 million and $26 million, respectively, of sales incentives to selling, general and administrative expense.

[**Table of Contents**](#TOC)

#### WASTE MANAGEMENT, INC.

#### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
*Long-Term Contracts*

Approximately 30% of our total revenue is derived from contracts with a remaining term greater than one year. The consideration for these contracts is primarily variable in nature. The variable elements of these contracts primarily include the number of homes and businesses served, weight, number of containers served and annual rate changes based on consumer price index, fuel prices or other operating costs. Such contracts are generally within our collection, recycling and other lines of business and have a weighted average remaining contract life of approximately four years. We do not disclose the value of unsatisfied performance obligations for these contracts as our right to consideration corresponds directly to the value provided to the customer for services completed to date and all future variable consideration is allocated to wholly unsatisfied performance obligations.

*Environmental Credits* 

We generate environmental credits through our production and sale of renewable energy. Our operating costs are associated with the production of renewable energy. The environmental credits are a form of government incentive generated through our renewable energy production and not as a result of the physical attributes of our production. The environmental credits are able to be separated and sold independent of the renewable energy produced. Thus, no cost is allocated to the environmental credit when it is generated.

#### Capitalized Interest
We capitalize interest on certain projects under development, including landfill expansion projects, certain assets under construction, including operating landfills and landfill gas-to-energy projects and internal-use software. During 2025, 2024 and 2023, total interest costs were $1.0 billion, $728 million and $590 million, respectively, of which $82 million, $84 million and $63 million were capitalized in 2025, 2024 and 2023, respectively.

#### Income Taxes
The Company is subject to income tax in the U.S., Canada and within parts of Western Europe. Current tax obligations associated with our income tax expense are reflected in the accompanying Consolidated Balance Sheets as a component of accrued liabilities and our deferred tax obligations are reflected in deferred income taxes.

Deferred income taxes are based on the difference between the financial reporting and tax basis of assets and liabilities. Deferred income tax expense represents the change during the reporting period in the deferred tax assets and liabilities, net of the effect of acquisitions and dispositions. Deferred tax assets include tax loss and credit carry-forwards and are reduced by a valuation allowance if, based on available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. We establish reserves for uncertain tax positions when, despite our belief that our tax return positions are supportable, we believe that certain positions may be challenged and potentially disallowed. When facts and circumstances change, we adjust these reserves through our income tax expense.

Should interest and penalties be assessed by taxing authorities on any underpayment of income tax, such amounts would be accrued and classified as a component of our income tax expense in our Consolidated Statements of Operations.

See Note 8 for discussion of our income taxes.

#### Contingent Liabilities
We estimate the amount of potential exposure we may have with respect to claims, assessments and litigation in accordance with authoritative guidance on accounting for contingencies. We are party to pending or threatened legal

[**Table of Contents**](#TOC)

#### WASTE MANAGEMENT, INC.

#### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
proceedings covering a wide range of matters in various jurisdictions. It is difficult to predict the outcome of litigation, as it is subject to many uncertainties. Additionally, it is not always possible for management to make a meaningful estimate of the potential loss or range of loss associated with such contingencies. See Note 10 for discussion of our commitments and contingencies.

#### Supplemental Cash Flow Information
The following table shows supplemental cash flow information for the year ended December 31 (in millions):

---

| | | | |
|:---|:---|:---|:---|
|  | **2025** | **2024** | **2023** |

---

During 2025, 2024 and 2023, we had $238 million, $474 million and $276 million, respectively, of non-cash financing activities primarily from our low-income housing investments and new financing leases. These are discussed further in Notes 6 and 8. Additionally, we had approximately $41 million, $20 million and $25 million of non-cash investing activities related to non-cash consideration transferred as part of our acquisitions in 2025, 2024 and 2023, respectively. See Note 17 for further discussion of our acquisitions.

*Restructuring*

During the year ended December 31, 2025, we recognized $51 million of pre-tax restructuring charges, primarily related to employee costs associated with the integration of Stericycle as well as employee retention and severance costs incurred to support automation at our recycling facilities and in certain back-office functions.

#### Adoption of New Accounting Standards in 2025
*Improvements to Income Tax Disclosures*

In December 2023, the Financial Accounting Standards Board ("FASB") issued ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures" ("ASU 2023-09") which improves the transparency of income tax disclosures by requiring specific categories in the income tax rate reconciliation and additional information for reconciling items that meet a quantitative threshold. Further, ASU 2023-09 requires certain disclosures on income taxes paid disaggregated by jurisdiction. ASU 2023-09 was effective for public entities for fiscal years beginning after December 15, 2024. The Company adopted ASU 2023-09 for the year ended December 31, 2025 on a retrospective basis and accordingly, our income tax disclosures for years 2024 and 2023 have been retrospectively recast under this guidance. See Note 8 for additional information.

See Note 5 for information regarding amortization of our intangible assets.

5.&nbsp;&nbsp;&nbsp;&nbsp;Goodwill and Other Intangible Assets

Goodwill was $13.9 billion and $13.4 billion as of December 31, 2025 and 2024, respectively. As discussed in Note 2, we perform our annual impairment test of goodwill balances for our reporting units using a measurement date of October 1. We will also perform interim tests if an impairment indicator exists. The $442 million increase in goodwill during 2025 is primarily related to our solid waste and recycling acquisitions. This increase was offset by a $16 million goodwill impairment charge to a business engaged in oil recovery and sludge processing services. This charge is reflected in Other Ancillary within our Collection and Disposal businesses. There were no impairments of goodwill or other intangible assets for the year ended December 31, 2024. See Notes 11 and 17 for additional information.

Goodwill is included within each segment's total assets. For segment reporting purposes, our recycling facilities and recycling brokerage services are included within our Recycling Processing and Sales segment. In 2025, we finalized the determination of our reporting units related to the Stericycle acquisition and allocated the goodwill balance to two reporting units within our Healthcare Solutions segment using a relative fair value allocation method. The following table presents changes in goodwill during the reported periods (in millions):

Amortization expense for other intangible assets was $421 million, $180 million and $129 million for 2025, 2024 and 2023, respectively. Additional information related to other intangible assets acquired through business combinations is included in Note 17. As of December 31, 2025 and 2024, we had $956 million and $970 million, respectively, of indefinite lived trade names, licenses, permits and other intangible assets that are not subject to amortization because they do not have stated expirations or have routine, administrative renewal processes. As of December 31, 2025, we expect annual amortization expense related to other intangible assets to be $383 million in 2026, $307 million in 2027, $271 million in 2028, $223 million in 2029 and $189 million in 2030. See Note 17 for additional information related to intangibles acquired from our acquisitions.

#### Debt Classification
As of December 31, 2025, we had approximately $3.7 billion of debt maturing within the next 12 months, including (i) $1.8 billion of tax-exempt bonds with term interest rate periods that expire within the next 12 months, which is prior to

[**Table of Contents**](#TOC)

#### WASTE MANAGEMENT, INC.

#### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
their scheduled maturities; (ii) $1.1 billion of short-term borrowings under our commercial paper program (net of related discount on issuance); (iii) $223 million of 7.1% senior notes that mature in August 2026; (iv) $364 million of 2.6% Canadian senior notes that mature in September 2026 and (v) $200 million of other debt with scheduled maturities within the next 12 months. As of December 31, 2025, we have classified $3.0 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 $711 million of debt maturing in the next 12 months is classified as current obligations.

#### Access to and Utilization of Credit Facilities and Commercial Paper Program
*$3.5 Billion Revolving Credit Facility —* Our $3.5 billion revolving credit facility, maturing May 2029, 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 a secured overnight financing rate administered by the Federal Reserve Bank of New York ("SOFR") or the Canadian Overnight Repo Rate Average ("CORRA") administered by the Bank of Canada, respectively, plus a spread depending on our senior public debt rating assigned by Moody's Investors Service, Inc. and Standard and Poor's Global Ratings. The spread above SOFR or CORRA can range from 0.585% to 1.025% per annum, plus applicable credit adjustments. We also pay certain other fees set forth in the $3.5 billion revolving credit facility agreement, including a facility fee based on the aggregate commitment, regardless of usage. As of December 31, 2025, we had no outstanding borrowings under this facility. We had $1.1 billion of outstanding borrowings (net of related discount on issuance) under our commercial paper program and $227 million of letters of credit issued, both supported by the facility, leaving unused and available credit capacity of $2.2 billion as of December 31, 2025.

The agreement includes a $1.0 billion accordion feature that may be used to increase total capacity in future periods, and we have the option to request up to two one-year extensions. Waste Management of Canada Corporation and WM Quebec Inc., each an indirect wholly-owned subsidiary of WMI, are borrowers under the $3.5 billion revolving credit facility, and the agreement permits borrowing in Canadian dollars up to the U.S. dollar equivalent of $375 million, with such borrowings to be repaid in Canadian dollars. WM Holdings, Inc. ("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 December 31, 2025, we had $1.1 billion of outstanding borrowings (net of related discount on issuance) under our commercial paper program.

*Other Letter of Credit Lines —* As of December 31, 2025, we had utilized $920 million of other uncommitted letter of credit lines with terms extending through December 2029.

#### Debt Borrowings and Repayments
*Commercial Paper Program* — During the year ended December 31, 2025, we made cash repayments of $20.4 billion, which were partially offset by $20.2 billion of cash borrowings (net of related discount on issuance).

*Senior Notes* — We repaid $422 million of 3.125% senior notes in March 2025 and $500 million of 0.75% senior notes in November 2025, in both cases with available cash at their scheduled maturities.

*Senior Notes Exchange Offer* — On June 25, 2025, we completed an exchange offer pursuant to which we issued approximately $483 million of new notes (the "Registered Notes") registered under the Securities Act of 1933, as amended, in exchange for a like amount of our outstanding unregistered 3.875% Senior Notes due 2029 (the "Restricted Notes").

[**Table of Contents**](#TOC)

#### WASTE MANAGEMENT, INC.

#### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
This amount represents approximately 99% of the $485 million aggregate principal amount of Restricted Notes that were originally issued on November 8, 2024, in a private offer in exchange for notes of Stericycle. The terms of the Registered Notes are substantially identical in all material respects to the terms of the Restricted Notes, except that the Registered Notes are not subject to restrictions on transfer. The debt exchange is accounted for as a modification of debt, as the financial terms of the Registered Notes do not differ from the Restricted Notes, and there is no substantial difference between the present value of cash flows under each respective set of notes.

*Tax-Exempt Bonds —* We issued $252 million of tax-exempt bonds in 2025. 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 and recycling facility construction and development. We also repaid $298 million of tax-exempt bonds in 2025 at their respective scheduled maturities with available cash on hand.

*Financing Leases and Other —* The increase in our financing leases and other debt obligations in 2025 is due to an increase of $248 million, primarily related to non-cash financing leases, partially offset by $153 million of cash repayments of debt at maturity. 

#### Scheduled Debt Payments
Principal payments of our debt for the next five years and thereafter, based on scheduled maturities are as follows: $1.8 billion in 2026, $2.0 billion in 2027, $2.0 billion in 2028, $2.1 billion in 2029, $1.7 billion in 2030 and $13.5 billion thereafter. Our recorded debt and financing lease obligations include non-cash adjustments associated with debt issuance costs, discounts and fair value adjustments attributable to terminated interest rate derivatives, which have been excluded from these amounts because they will not result in cash payments. As discussed above, we have the intent and ability to refinance our commercial paper borrowings on a long-term basis. See Note 7 below for further discussion of our financing lease arrangements.

#### Secured Debt
Our debt balances are generally unsecured, except for financing lease obligations and the notes payable associated with our investments in low-income housing properties. See Notes 8 and 18 for additional information related to these investments.

#### Debt Covenants
The terms of certain of our financing arrangements require that we comply with financial and other covenants. Our most restrictive financial covenant is the one contained in our $3.5 billion revolving credit facility, which sets forth a maximum total debt to consolidated earnings before interest, taxes, depreciation, depletion and amortization ratio (the "Leverage Ratio"). This covenant requires that the Leverage Ratio for the preceding four fiscal quarters will not be more than 3.75 to 1, provided that if an acquisition permitted under our $3.5 billion revolving credit facility involving aggregate consideration in excess of $200 million occurs during the fiscal quarter, the Company shall have the right to increase the Leverage Ratio to 4.25 to 1 during such fiscal quarter and for the following three fiscal quarters (the "Elevated Leverage Ratio Period"). There shall be no more than two Elevated Leverage Ratio Periods during the term of our $3.5 billion revolving credit facility, and the Leverage Ratio must return to 3.75 to 1 for at least one fiscal quarter between Elevated Leverage Ratio Periods. The Company has not elected to increase the Leverage Ratio for an Elevated Leverage Ratio Period during the term of our $3.5 billion revolving credit facility. The calculation of all components used in the Leverage Ratio covenant are as defined in the $3.5 billion revolving credit facility. As of December 31, 2025 and 2024, we were in compliance with our Leverage Ratio covenant.

[**Table of Contents**](#TOC)

#### WASTE MANAGEMENT, INC.

#### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
Our $3.5 billion revolving credit facility, senior notes and other financing arrangements also contain certain restrictions on the ability of the Company's subsidiaries to incur additional indebtedness as well as restrictions on the ability of the Company and its subsidiaries to, among other things, incur liens, engage in sale-leaseback transactions and engage in mergers and consolidations. We monitor our compliance with these restrictions, but do not believe that they significantly impact our ability to enter into investing or financing arrangements typical for our business. As of December 31, 2025 and 2024, we were in compliance with all covenants and restrictions under our financing arrangements, in addition to our Leverage Ratio covenant, that may have a material effect on our Consolidated Financial Statements.

**7.&nbsp;&nbsp;&nbsp;&nbsp;Leases**

Our operating lease activities primarily consist of leases for real estate, landfills (as discussed further in Note 2), fleet vehicles and operating equipment. Our financing lease activities primarily consist of leases for operating equipment, railcars and landfill assets. Leases with an initial term of 12 months or less, which are not expected to be renewed beyond one year, are not recorded on the balance sheet and are recognized as lease expense on a straight-line basis over the lease term. Most leases include one or more options to renew, with renewal terms generally ranging from one to 10 years. The exercise of lease renewal options is generally at our sole discretion. We include the renewal term in the calculation of the right-of-use asset and related lease liability when such renewals are reasonably certain of being exercised. Certain leases also include options to purchase the leased property. The depreciable life of assets and leasehold improvements is limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise. Certain of our lease agreements include rental payments based on usage, and other lease agreements include rental payments adjusted periodically for inflation; these payments are treated as variable lease payments. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants.

When the implicit interest rate is not readily available for our leases, we discount future cash flows of the remaining lease payments using the current interest rate that would be paid to borrow on collateralized debt over a similar term, or incremental borrowing rate, at the commencement date.

Supplemental balance sheet information for our leases as of December 31 is as follows (in millions):

Cash paid during 2025 for our operating and financing leases was $214 million and $101 million, respectively. Cash paid during 2024 for our operating and financing leases was $103 million and $90 million, respectively. Increases in cash paid for operating leases was primarily driven by activity within our Healthcare Solutions segment. During 2025, right-of-use assets obtained in exchange for lease obligations for our operating and financing leases were $132 million and $184 million, respectively. During 2024, right-of-use assets obtained in exchange for lease obligations for our operating and financing leases were $74 million and $118 million, respectively.

As of December 31, 2025, the weighted average remaining lease terms of our operating and financing leases were approximately 12 years and 10 years, respectively. The weighted average discount rates used to determine the lease liabilities as of December 31, 2025 for our operating and financing leases were approximately 4.4% and 4.9%, respectively.

*Renewable Natural Gas —* Through our Renewable Energy segment, we have invested in building landfill gas-to-energy facilities in the U.S. and Canada that produce renewable electricity and RNG. We expect our new RNG facilities to qualify for federal tax credits and to realize those credits through 2027 under Section 48 of the Internal Revenue Code. We completed construction of seven RNG facilities in 2025, five RNG facilities in 2024 and one RNG facility in 2023, resulting in a reduction to our income tax expense of $184 million, $137 million and $8 million, respectively.

*Low-Income Housing —* 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 2036 under Section 42 and Section 45D of the Internal Revenue Code.

As a result of adopting ASU 2023-02 in 2024, we amortize our investments in these entities using the proportional amortization method. Under the proportional amortization method, the equity investment is amortized in proportion to the income tax credits and other income tax benefits received. The amortization expense and the income tax credits are required to be presented on a net basis in income tax expense on the Consolidated Statements of Operations. Prior to 2024, we accounted 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 income (loss) of unconsolidated entities, within our Consolidated Statements of Operations.

During the years ended December 31, 2025 and 2024, we recognized income tax expense of $96 million and $78 million, respectively, related to amortization under ASU 2023-02 and a reduction in our income tax expense of $137 million and $104 million, respectively, primarily due to federal tax credits realized from these investments. For the year ended December 31, 2023, we recognized net losses of $66 million and a reduction in our income tax expense of $108 million 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 years ended December 31, 2025, 2024 and 2023, we recognized interest expense of $33 million, $24 million and $15 million, respectively, associated with our investments in low-income housing properties. See Notes 2 and 18 for additional information related to these unconsolidated variable interest entities.

*Tax Implications of Impairments* — During the years ended December 31, 2024 and 2023, we recognized additional income tax expense of $14 million and $50 million, respectively, due to non-cash impairment charges that were not deductible for tax purposes in the year of impairment. The non-cash impairment charges recognized during 2025 were deductible for tax purposes. See Note 11 for more information related to our impairment charges.

*Tax Audits —* 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. In the fourth quarter of 2024, the Company filed a claim for refund of the entire amount deposited with the IRS. We expect to litigate any denial of the claim for refund. As of December 31, 2025 and 2024, the IRS deposit, net of reserve for uncertain tax positions, was classified as a component of other long-term assets in the Company's Consolidated Balance Sheets.

In addition, we are under IRS audits for the 2024 and 2025 tax years and expect the audits to be completed within the next 15 months. We are also currently undergoing audits by the Canada Revenue Agency for the 2021 tax year and various state and local jurisdictions for tax years that date back to 2018.

*Tax Legislation* — On July 4, 2025, President Trump signed the One Big Beautiful Bill Act into law. We have evaluated the business tax provisions in the legislation, none of which had a material impact on our effective tax rate. However, we had a beneficial impact to cash taxes related to bonus depreciation.

The components of net deferred tax liabilities as of December 31 are as follows (in millions):

---

| | | |
|:---|:---|:---|
|  | **2025** | **2024** |
| Deferred tax assets: |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;Net operating loss, capital loss and tax credit carry-forwards | $160 | $159 |
| &nbsp;&nbsp;&nbsp;&nbsp;Landfill and environmental remediation liabilities | 146 | 162 |
| &nbsp;&nbsp;&nbsp;&nbsp;Operating lease liabilities | 258 | 276 |
| &nbsp;&nbsp;&nbsp;&nbsp;Miscellaneous and other reserves, net | 176 | 258 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Total deferred tax assets | 740 | 855 |
| Valuation allowance | (180) | (199) |
| Deferred tax liabilities: |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;Property and equipment | (1614) | (1308) |
| &nbsp;&nbsp;&nbsp;&nbsp;Goodwill and other intangibles | (1844) | (1895) |
| &nbsp;&nbsp;&nbsp;&nbsp;Operating lease right-of-use assets | (245) | (263) |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Net deferred tax liabilities | $(3143) | $(2810) |

---

These net deferred tax liabilities are included as a component of other long-term assets, accrued liabilities and deferred income taxes in our Consolidated Balance Sheets. As of December 31, 2025, we had $114 million of international net operating loss carry-forwards with expiration dates through 2034 and $2.2 billion of state net operating loss carry-forwards with expiration dates through 2045. We also had $46 million of foreign interest expense carry-forwards that do not expire, $40 million of foreign tax credit carry-forwards with expiration dates through 2033 and $5 million of state tax credit carry-forwards with expiration dates through 2038.

We have established valuation allowances for uncertainties in realizing the benefit of certain tax loss and credit carry-forwards and other deferred tax assets. While we expect to realize the deferred tax assets, net of the valuation allowances, changes in estimates of future taxable income or in tax laws may alter this expectation.

#### Liabilities for Uncertain Tax Positions
A reconciliation of the beginning and ending amount of gross unrecognized tax benefits, including accrued interest, is as follows (in millions):

---

| | | | |
|:---|:---|:---|:---|
|  | **2025** | **2024** | **2023** |
| Balance as of January 1 | $43 | $66 | $64 |
| &nbsp;&nbsp;Additions based on tax positions related to the current year | 6 | 4 | 6 |
| &nbsp;&nbsp;Accrued interest | 2 | 2 | 2 |
| &nbsp;&nbsp;Acquisitions |  | 2 |  |
| &nbsp;&nbsp;Settlements |  | (21) |  |
| &nbsp;&nbsp;Lapse of statute of limitations | (8) | (10) | (6) |
| Balance as of December 31 | $43 | $43 | $66 |

---

These liabilities are included as a component of other long-term liabilities or as an offset to other long-term assets in our Consolidated Balance Sheets. As of December 31, 2025, we had $36 million of net unrecognized tax benefits that, if recognized in future periods, would impact our effective income tax rate.

We recognize interest expense related to unrecognized tax benefits in our income tax expense, which was not material for the reported periods. We did not have any material accrued liabilities or expense for penalties related to unrecognized tax benefits for the reported periods.

9. Employee Benefit Plans

*Defined Contribution Plans —* The Company sponsors a 401(k) retirement savings plan that covers employees, except those working subject to collective bargaining agreements that do not provide for coverage under the plan. U.S. employees who are not subject to such collective bargaining agreements are generally eligible to participate in the plan following a 90-day waiting period after hire and may contribute as much as 50% of their eligible annual compensation and 80% of their annual incentive plan bonus, subject to annual contribution limitations established by the IRS. Under the 401(k) retirement savings plan, for non-union employees, we match 100% of employee contributions on the first 3% of their eligible annual compensation and 50% of employee contributions on the next 3% of their eligible annual compensation, resulting in a maximum match of 4.5% of eligible annual compensation. Non-union employees are automatically enrolled in the plan at a 3% contribution rate upon eligibility. Both employee and Company contributions are in cash and vest immediately. In connection with our acquisition of Stericycle in November 2024, we acquired a domestic defined contribution plan with attributes similar to our existing Waste Management 401(k) retirement savings plan. In January 2026, the Stericycle 401(k) plan was merged into the Waste Management 401(k) retirement savings plan.

Certain U.S. employees who are subject to collective bargaining agreements may participate in the 401(k) retirement savings plan under terms specified in their collective bargaining agreement. Certain employees outside the U.S., including those in Canada and across Europe, participate in defined contribution plans maintained by the Company in compliance with laws of the appropriate jurisdiction. Charges to operating and selling, general and administrative expenses for our defined contribution plans totaled $157 million, $125 million and $118 million for the years ended December 31, 2025, 2024 and 2023, respectively.

*Defined Benefit Plans (other than multiemployer defined benefit pension plans discussed below) —* WM Holdings sponsors a defined benefit plan for certain employees who are subject to collective bargaining agreements that provide for participation in this plan. Further, certain of our Canadian subsidiaries sponsor defined benefit plans that are frozen to new participants. As of December 31, 2025, the combined benefit obligation of these pension plans was $118 million supported by $123 million of combined plan assets, resulting in a net plan asset for these plans of $5 million. As of December 31,

[**Table of Contents**](#TOC)

#### WASTE MANAGEMENT, INC.

#### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
2024, the combined benefit obligation of these pension plans was $115 million supported by $117 million of combined plan assets, resulting in a net plan asset for these plans of $2 million.

In addition, WM Holdings and certain of its subsidiaries provided post-retirement health care and other benefits to eligible retirees. In conjunction with our acquisition of WM Holdings in July 1998, we limited participation in these plans to participating retirees as of December 31, 1998. The unfunded benefit obligation for these plans was $6 million and $7 million as of December 31, 2025 and 2024, respectively.

Our assets and accrued benefit liabilities for our defined benefit pension and other post-retirement plans are included as components of other long-term assets, accrued liabilities and other long-term liabilities in our Consolidated Balance Sheets.

*Multiemployer Defined Benefit Pension Plans —* We are a participating employer in a number of trustee-managed multiemployer defined benefit pension plans ("Multiemployer Pension Plans") for employees who are covered by collective bargaining agreements. The risks of participating in these Multiemployer Pension Plans are different from single-employer plans in that (i) assets contributed to the Multiemployer Pension Plan by one employer may be used to provide benefits to employees or former employees of other participating employers; (ii) if a participating employer stops contributing to the plan, the unfunded obligations of the plan may be required to be assumed by the remaining participating employers and (iii) if we choose to stop participating in any of our Multiemployer Pension Plans, we may be required to pay those plans a withdrawal amount based on the underfunded status of the plan. The following table outlines our participation in Multiemployer Pension Plans considered to be individually significant (dollars in millions):

&nbsp;&nbsp;&nbsp;&nbsp;(a) Unless otherwise noted in the table above, the most recent Pension Protection Act zone status available in 2025 and 2024 is for the plan's year-end as of December 31, 2024 and 2023, respectively. The zone status is based on information that we received from the plan and is certified by the plan's actuary. As defined in the Pension Protection Act of 2006, among other factors, plans reported as critical are generally less than 65% funded and plans reported as endangered are generally less than 80% funded. Under the Multiemployer Pension Reform Act of 2014, a plan is

[**Table of Contents**](#TOC)

#### WASTE MANAGEMENT, INC.

#### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
generally in critical and declining status if it (i) is certified to be in critical status pursuant to the Pension Protection Act of 2006 and (ii) is projected to be insolvent within the next 15 years or, in certain circumstances, 20 years.

&nbsp;&nbsp;&nbsp;&nbsp;(b) The "FIP/RP Status" column indicates plans for which a Funding Improvement Plan ("FIP") or a Rehabilitation Plan ("RP") has been implemented.

&nbsp;&nbsp;&nbsp;&nbsp;(c) A Multiemployer Pension Plan that has been certified as endangered, seriously endangered or critical may begin to levy a statutory surcharge on contribution rates. Once authorized, the surcharge is at the rate of 5% for the first 12 months and 10% for any periods thereafter. Contributing employers, however, may eliminate the surcharge by entering into a collective bargaining agreement that meets the requirements of the applicable FIP or RP.

&nbsp;&nbsp;&nbsp;&nbsp;(d) Of the Multiemployer Pension Plans considered to be individually significant, the Company was listed in the Form 5500 of the Suburban Teamsters of Northern Illinois Pension Plan as providing more than 5% of the total contributions for plan years ending December 31, 2025 and 2024.

&nbsp;&nbsp;&nbsp;&nbsp;(e) Total contributions to Multiemployer Pension Plans exclude contributions related to withdrawal liabilities, if any.

Our portion of the projected benefit obligation, plan assets and unfunded liability for the Multiemployer Pension Plans is not material to our financial position. However, the failure of participating employers to remain solvent could affect our portion of the plans' unfunded liability. Specific benefit levels provided by union pension plans are not negotiated with or known by the employer contributors.

In connection with our ongoing renegotiations of various collective bargaining agreements, we may discuss and negotiate for the complete or partial withdrawal from one or more of these pension plans. Further, business events, such as the discontinuation or nonrenewal of a customer contract, the decertification of a union, or relocation, reduction or discontinuance of certain operations, which result in the decline of Company contributions to a Multiemployer Pension Plan could trigger a partial or complete withdrawal. In the event of a withdrawal, we may incur expenses associated with our obligations for unfunded vested benefits at the time of the withdrawal. Refer to Note 10 for additional information related to our obligations to Multiemployer Pension Plans.

*Multiemployer Plan Benefits Other Than Pensions —* During the years ended December 31, 2025, 2024 and 2023, the Company made contributions of $76 million, $62 million and $56 million, respectively, to multiemployer health and welfare plans that also provide other post-retirement employee benefits. Funding of benefit payments for plan participants are made at negotiated rates in the respective collective bargaining agreements as costs are incurred.

10. 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 6. 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.

[**Table of Contents**](#TOC)

#### WASTE MANAGEMENT, INC.

#### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
*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. Our receivable balance associated with insurance claims was $138 million and $111 million as of December 31, 2025 and 2024, respectively. The changes to our insurance reserves for the year ended December 31 are summarized below (in millions):

---

| | | |
|:---|:---|:---|
|  | **2025(a)** | **2024** |
| Balance as of January 1 | $798 | $712 |
| &nbsp;&nbsp;&nbsp;&nbsp;Self-insurance expense | 277 | 243 |
| &nbsp;&nbsp;&nbsp;&nbsp;Cash paid and other | (225) | (231) |
| &nbsp;&nbsp;&nbsp;&nbsp;Assumed liabilities from acquisitions |  | 74 |
| Balance as of December 31 | $850 | $798 |
| &nbsp;&nbsp;&nbsp;&nbsp;Current portion as of December 31 | $216 | $211 |
| &nbsp;&nbsp;&nbsp;&nbsp;Long-term portion as of December 31 | $634 | $587 |

---

&nbsp;&nbsp;&nbsp;&nbsp;(a) Based on current estimates, we anticipate that most of our insurance reserves will be settled in cash over the next six years .

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.

*Unconditional Purchase Obligations* — Our unconditional purchase obligations are generally established in the ordinary course of our business and are structured in a manner that provides us with access to important resources at competitive, market-driven rates and consist primarily of the following:

● *Disposal —* We have several agreements expiring at various dates through 2052 that require us to dispose of a minimum number of tons at third-party disposal facilities. Under these put-or-pay agreements, we are required to pay for the agreed upon minimum volumes regardless of the actual number of tons placed at the facilities. We generally fulfill our minimum contractual obligations by disposing of volumes collected in the ordinary course of business at these disposal facilities.

● *Other —* We are party to certain multi-year service agreements, including various contracts to support our Renewable Energy segment, such as interconnection agreements, expiring at various dates through 2046 requiring minimum annual payments.

As of December 31, 2025, our estimated minimum obligations associated with unconditional purchase obligations were $269 million in 2026, $234 million in 2027, $130 million in 2028, $78 million in 2029, $63 million in 2030 and $594 million thereafter. We may also establish unconditional purchase obligations in conjunction with acquisitions or divestitures. Our future minimum obligations under these outstanding purchase agreements are generally quantity driven

[**Table of Contents**](#TOC)

#### WASTE MANAGEMENT, INC.

#### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
and, as a result, our associated financial obligations are not fixed as of December 31, 2025. For contracts that require us to purchase minimum quantities of goods or services, we have estimated our future minimum obligations based on the current market values of the underlying products or services or contractually stated amounts. We currently expect the products and services provided by these agreements to continue to meet the needs of our ongoing operations. Therefore, we do not expect these established arrangements to materially impact our future financial condition, results of operations or cash flows.

*Other Commitments*

● *Royalties —* We have various arrangements that require us to make royalty payments to third parties including prior landowners, lessors or host communities where our operations are located. Our obligations generally are based on per ton rates for waste actually received at our transfer stations or landfills. Royalty agreements that are non-cancelable and require fixed or minimum payments are included in our financing leases and other debt obligations in our Consolidated Balance Sheets as disclosed in Note 6. Additionally, our Collection and Disposal and Corporate and Other businesses earn royalties from our Renewable Energy segment related to the transfer of landfill gas to our Renewable Energy segment from our active and closed landfills. All royalties between our Renewable Energy segment and Collection and Disposal and Corporate and Other businesses are eliminated in consolidation.

*Guarantees —* We have entered into the following guarantee agreements associated with our operations:

● As of December 31, 2025, WM Holdings has fully and unconditionally guaranteed all of WMI's senior indebtedness, including its senior notes which mature through 2054, $3.5 billion revolving credit facility and certain letter of credit lines. WMI has fully and unconditionally guaranteed the senior indebtedness of WM Holdings, which matures in 2026. Performance under these guarantee agreements would be required if either party defaulted on their respective obligations. No additional liabilities have been recorded for these intercompany guarantees because all of the underlying obligations are reflected in our Consolidated Balance Sheets.

● WMI and WM Holdings have guaranteed subsidiary debt obligations, including tax-exempt bonds, financing leases and other indebtedness. If a subsidiary fails to meet its obligations associated with its debt agreements as they come due, WMI or WM Holdings will be required to perform under the related guarantee agreement. No additional liabilities have been recorded for these intercompany guarantees because all of the underlying obligations are reflected in our Consolidated Balance Sheets. See Note 6 for information related to the balances and maturities of these debt obligations.

● Certain of our subsidiaries have guaranteed the market or contractually-determined value of certain homeowners' properties that are adjacent to or near certain of our landfills. These guarantee agreements extend over the life of the respective landfill. Under these agreements, we would be responsible for the difference, if any, between the sale value and the guaranteed market or contractually-determined value of the homeowners' properties. As of December 31, 2025, we have agreements guaranteeing certain market value losses for certain properties adjacent to or near 18 of our landfills. Any liability associated with the triggering of the home value guarantee has been reflected in our Consolidated Balance Sheets. 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.

● We have indemnified the purchasers of businesses or divested assets for the occurrence of specified events under certain of our divestiture agreements. Other than certain identified items that are currently recorded as obligations, we do not believe that it is possible to determine the contingent obligations associated with these indemnities. Additionally, under certain of our acquisition agreements, we have provided for additional consideration to be paid to the sellers if established financial targets or other market conditions are achieved post-closing and we have recognized liabilities for these contingent obligations based on an estimate of the fair value of these contingencies at the time of acquisition. We do not currently believe that contingent obligations to provide indemnification or pay additional post-closing consideration in connection with our divestitures or acquisitions

[**Table of Contents**](#TOC)

#### WASTE MANAGEMENT, INC.

#### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
will have a material adverse effect on the Company's business, financial condition, results of operations or cash flows.

● WMI and WM Holdings guarantee the service, lease, financial and general operating obligations of certain of their subsidiaries. If such a subsidiary fails to meet its contractual obligations as they come due, the guarantor has an unconditional obligation to perform on its behalf. No additional liability has been recorded for service, financial or general operating guarantees because the subsidiaries' obligations are properly accounted for as costs of operations as services are provided or general operating obligations as incurred. No additional liability has been recorded for the lease guarantees because the subsidiaries' obligations are properly accounted for as operating or financing leases, as appropriate.

*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 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.

As of December 31, 2025, we had been notified by the government that we are a PRP in connection with 75 locations listed on the EPA's Superfund National Priorities List ("NPL"). Of the 75 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 61 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.

In 2018, both of McGinnes Industrial Maintenance Corporation ("MIMC"), a subsidiary of Waste Management of Texas, Inc., and International Paper Company ("IPC") entered into an Administrative Order on Consent with the EPA as PRPs to develop a remedial design for the San Jacinto River Waste Pits Superfund Site in Harris County, Texas. 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. In November 2024, MIMC and IPC publicly issued a proposed revised full remedial design that was approved by the EPA in September 2025. It is expected that the EPA will issue a Unilateral Administrative Order for the site cleanup in the first quarter of 2026. The recorded liability as of December 31, 2025 and 2024, was approximately $100 million and $97 million, respectively.

[**Table of Contents**](#TOC)

#### WASTE MANAGEMENT, INC.

#### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
MIMC's ultimate liability could be materially different from current estimates, including potential increases resulting from MIMC's continued engagement with the EPA regarding a final remedial design for the site.

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. We are not aware of any matters as of year end 2025 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.

On November 4, 2024, the Company acquired Stericycle. At the time of the acquisition, Stericycle was subject to the following legal matter, which is now a legal matter of our wholly-owned subsidiary.

On February 11, 2020, Stericycle received an administrative subpoena from the U.S. Drug Enforcement Administration ("DEA"), which executed a search warrant at a facility in Rancho Cordova, California and an administrative inspection warrant at a facility in Indianapolis, Indiana for materials related to Stericycle's now-divested Domestic Environmental Solutions business of collecting, transporting, and destroying controlled substances from retail customers (the "ESOL Retail Controlled Substances Business"). On that same day, agents from the California Department of Toxic Substances Control executed a separate search warrant at the Rancho Cordova facility. Since that time, the U.S. Attorney's Office for the Eastern District of California ("USAO EDCA") has been overseeing criminal and civil investigations of the ESOL Retail Controlled Substances Business. The USAO EDCA informed Stericycle that the investigations relate to Stericycle's operation and sale of its ESOL Retail Controlled Substances Business that was divested in 2020 and has asserted that Stericycle and some of Stericycle's current or former employees may have civil and criminal liability under the Controlled Substances Act and other federal statutes related to that business. Stericycle has been cooperating with the ongoing investigations, which are limited to the period of Stericycle's historical operation and ownership of the ESOL Retail Controlled Substances Business from 2015 through

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2020. While the ultimate disposition of this matter remains uncertain, we do not currently believe that it 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 was appointed and an amended complaint was filed in January 2023. The amended complaint sought 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 of 1934, as amended, based on alleged misrepresentations and omissions concerning the anticipated time for completion of our acquisition of Advanced Disposal. On December 18, 2025, the court granted final approval of a settlement that will be covered by insurance. This settlement will not 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 15% of our workforce is covered by collective bargaining agreements with various local unions across the U.S. and Canada, and certain parts of Europe. As a result of some of these agreements, certain of our subsidiaries are participating employers in a number of Multiemployer Pension Plans for the covered employees. Refer to Note 9 for additional information about our participation in Multiemployer Pension Plans considered individually significant. 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 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. 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. In the fourth quarter of 2024, the Company filed a claim for refund of the entire amount deposited with the IRS. We

expect to litigate any denial of the claim for refund. As of December 31, 2025 and 2024, the IRS deposit, net of reserve for uncertain tax positions, was classified as a component of other long-term assets in the Company's Consolidated Balance Sheets.

Refer to Note 5 for further information.

During the year ended December 31, 2024, we recognized $82 million of net charges primarily consisting of (i) a $54 million charge required to increase the estimated fair value of a liability associated with the expected disposition of an investment the Company holds in a waste diversion technology business within Corporate and Other; (ii) a $14 million loss associated with the divestiture of a minority investment in a medical waste company within Corporate and Other, in connection with our acquisition of Stericycle and (iii) a $13 million charge pertaining to reserves for loss contingencies in our Corporate and Other to adjust an indirect wholly-owned subsidiary's estimated potential share of the liability for a proposed environmental remediation plan at a closed site.

During the year ended December 31, 2023, we recognized $243 million of net charges primarily consisting of (i) a $168 million goodwill impairment charge within our Recycling Processing and Sales segment related to a business engaged in accelerating film and plastic wrap recycling capabilities, with $22 million attributable to noncontrolling interests. This charge was partially offset by the recognition of $46 million of income related to the reversal of a liability for contingent consideration associated with our investment in such business; (ii) $107 million of impairment charges within Corporate and Other for certain investments in waste diversion technology businesses and (iii) a $17 million charge within Corporate and Other 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 financial statement impacts are largely related to our noncontrolling interests in entities established to invest in and manage low-income housing properties. In 2024, we adopted ASU 2023-02, and, as a result, beginning in 2024, the amortization of these investments is recognized as a component of income tax expense. We generate tax credits and other tax benefits from the losses incurred from these investments. The losses are more than offset by the tax benefits generated by these investments as further discussed in Note 8. Refer to Notes 8 and 18 for additional information related to these investments.

13. Capital Stock, Dividends and Common Stock Repurchase Program

#### Capital Stock
We have 1.5 billion shares of authorized common stock with a par value of $0.01 per common share. As of December 31, 2025, we had 402.9 million shares of common stock issued and outstanding. The Board of Directors is authorized to issue preferred stock in series, and with respect to each series, to fix its designation, relative rights (including voting, dividend, conversion, sinking fund, and redemption rights), preferences (including dividends and liquidation) and limitations. We have 10 million shares of authorized preferred stock, $0.01 par value, none of which is currently outstanding.

#### Dividends
Our quarterly dividends have been declared by our Board of Directors. Cash dividends declared and paid were $1.3 billion in 2025, or $3.30 per common share, $1.2 billion in 2024, or $3.00 per common share, and $1.1 billion in 2023, or $2.80 per common share.

In December 2025, we announced that our Board of Directors expects to increase the quarterly dividend from $0.825 to $0.945 per share for dividends declared in 2026. However, all future dividend declarations are at the discretion of our Board of Directors and depend on various factors, including our net earnings, financial condition, cash required for future business plans, growth and acquisitions and other factors the Board of Directors may deem relevant.

#### Common Stock Repurchase Program
The Company repurchases shares of its common stock as part of capital allocation programs authorized by our Board of Directors. Share repurchases are a part of our long-term strategy and incorporated into our overall capital allocation plan to enhance our Company's performance, in conjunction with our other uses of capital, and to return value to stockholders in a tax-efficient manner. Share repurchases during the reported periods were completed through accelerated share repurchase ("ASR") agreements and, to a lesser extent, open market transactions. The terms of these ASR agreements required that we deliver cash at the beginning of each ASR repurchase period. In exchange, we received a portion of the total shares expected to be repurchased based on the then-current market price of our common stock. The remaining shares repurchased over the course of each repurchase period are delivered to us once the repurchase period is complete. In the table below, shares repurchased are measured and reported based on the period shares are delivered to us, which can differ from the period cash is delivered to a repurchase agent for the value of such shares. The following is a summary of our share repurchases under our common stock repurchase program for the year ended December 31:

---

| | | | |
|:---|:---|:---|:---|
|  | **2025(a)** | **2024(b)** | **2023(c)** |
| Shares repurchased (in thousands) |  | 1494 | 7840 |
| Weighted average price per share  | $— | $196.95 | $158.47 |
| Total repurchases (in millions) | $— | $262 | $1242 |

---

&nbsp;&nbsp;&nbsp;&nbsp;(a) There were no common stock repurchases for the year ended December 31, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;(b) We executed and completed one ASR agreement during 2024 to repurchase $250 million of our common stock and received 1.2 million shares in connection with this ASR agreement. In February 2024, we also received 0.2 million shares pursuant to our October 2023 ASR agreement based on a final weighted average price of $175.29 .

We also repurchased an additional 0.1 million shares of our common stock in open market transactions in compliance with Rule 10b5-1 and Rule 10b 18 of the Securities Exchange Act of 1934 ("Exchange Act") for $12 million, inclusive of per-share commission.

[**Table of Contents**](#TOC)

#### WASTE MANAGEMENT, INC.

#### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
&nbsp;&nbsp;&nbsp;&nbsp;(c) We executed and completed three ASR agreements during 2023 to repurchase $950 million of our common stock and received 6.0 million shares in connection with these ASR agreements. Additionally, in October 2023, we executed an ASR agreement to repurchase $300 million of our common stock. At the beginning of the repurchase period, we delivered $300 million in cash and received 1.5 million shares based on a stock price of $161.38 . The ASR agreement completed in February 2024, at which time we received 0.2 million additional shares based on a final weighted average price of $175.29 .

We also repurchased an additional 0.3 million shares of our common stock in open market transactions in compliance with Rule 10b5-1 and Rule 10b 18 of the Securities Exchange Act of 1934 ("Exchange Act") for $52 million, inclusive of per-share commissions.

We announced in December 2025 that our Board of Directors has authorized up to $3.0 billion in future share repurchases, exclusive of fees, commissions and taxes. This new authorization supersedes and replaces remaining authority under the prior Board of Directors' authorization for share repurchases announced in December 2023. The amount of future share repurchases executed under our Board of Directors' authorization is determined in management's discretion, based on various factors, including our leverage level, net earnings, financial condition and cash required for future business plans, growth and acquisitions.

14. Equity-Based Compensation

#### Employee Stock Purchase Plan
We have an Employee Stock Purchase Plan ("ESPP") under which employees that have been employed for at least 30 days may purchase shares of our common stock at a discount. The plan provides for two offering periods for purchases: January through June and July through December. At the end of each offering period, enrolled employees purchase shares of our common stock at a price equal to 85% of the market value on the last day of the applicable offering period. The purchases are made at the end of an offering period with funds accumulated through payroll deductions over the course of the offering period. Subject to limitations set forth in the plan and under IRS regulations, eligible employees may elect to have up to 10% of their base pay deducted during the offering period. The total number of shares issued under the plan for the offering periods in 2025, 2024 and 2023 was approximately 438,000, 408,000 and 473,000, respectively. After the January 2026 issuance of shares associated with the July to December 2025 offering period, 0.9 million shares remain available for issuance under the ESPP.

Annual compensation expense resulting from our ESPP was $13 million, or $10 million net of tax expense, for 2025, $11 million, or $8 million net of tax expense, for 2024 and $14 million, or $11 million net of tax expense, for 2023.

#### Employee Stock Incentive Plans
In May 2023, our stockholders approved our 2023 Stock Incentive Plan (the "2023 Plan") to replace our 2014 Stock Incentive Plan (the "2014 Plan"). Upon approval of the 2023 Plan, no further awards could be granted under the 2014 Plan, and the 15.2 million shares of our common stock that were previously available for issuance under the 2014 Plan became available for issuance under the 2023 Plan, in addition to any shares of our common stock that were subject to outstanding awards under the 2014 Plan that subsequently cease to be subject to such awards as a result of the forfeiture, cancellation or termination. We did not request that our stockholders approve any shares in addition to the shares that roll over from the 2014 Plan for issuance pursuant to the 2023 Plan. As of December 31, 2025, approximately 12.9 million shares were available for future grants under the 2023 Plan. Our equity-based compensation awards described herein have been made pursuant to our 2023 Plan or our 2014 Plan (collectively, the "Incentive Plans"). We currently utilize treasury shares to meet the needs of our equity-based compensation programs.

[**Table of Contents**](#TOC)

#### WASTE MANAGEMENT, INC.

#### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
Pursuant to the 2023 Plan, we can issue cash awards, stock options, stock appreciation rights, phantom stock and stock awards, including restricted stock, restricted stock units ("RSUs") and performance share units ("PSUs"). The terms and conditions of equity awards granted under the Incentive Plans are determined by the Management Development and Compensation Committee of our Board of Directors.

The 2025 annual stock incentive plan awards granted to the Company's senior leadership team, which generally includes the Company's executive officers, included a combination of PSUs and stock options. Awards granted to other eligible employees under the Incentive Plans included a combination of PSUs, RSUs and stock options in 2025. The Company also periodically grants equity awards, primarily consisting of RSUs, to employees working on key initiatives, in connection with new hires and promotions and to field and corporate managers.

*Restricted Stock Units —* A summary of our RSUs is presented in the table below (units in thousands):

---

| | | |
|:---|:---|:---|
|  | <br>**Units** | **Weighted Average**<br>**Per Share**<br>**Fair Value** |
| Unvested as of January 1, 2025 | 472 | $179.25 |
| Granted | 189 | $230.51 |
| Vested | (220) | $174.62 |
| Forfeited | (21) | $210.84 |
| Unvested as of December 31, 2025 | 420 | $203.17 |

---

The total fair market value of RSUs that vested during the years ended December 31, 2025, 2024 and 2023 was $50 million, $25 million and $15 million, respectively. During the year ended December 31, 2025, we issued approximately 149,000 shares of common stock for these vested RSUs, net of approximately 71,000 units deferred or used for payment of associated taxes.

RSUs may not be voted or sold by award recipients until time-based vesting restrictions have lapsed. RSUs currently outstanding primarily provide for three-year cliff vesting and include dividend equivalents accumulated during the vesting period. Unvested units are subject to forfeiture in the event of voluntary or for-cause termination. RSUs are generally subject to pro-rata vesting upon an employee's involuntary termination other than for cause and generally payout at the end of the three-year vesting period and become immediately vested in the event of an employee's death or disability.

Compensation expense associated with RSUs is measured based on the grant-date fair value of our common stock and is recognized on a straight-line basis over the required employment period. RSUs generally continue to vest following a qualifying retirement as if the employee had remained employed until the end of the vesting period, and compensation expense for RSUs granted to retirement eligible employees is recognized over the longer of (i) the period between grant date and the date that the recipient becomes retirement-eligible or (ii) the defined service requirement of the award. Compensation expense is only recognized for those awards that we expect to vest, which we estimate based upon an assessment of expected forfeitures.

*Performance Share Units —* There are primarily two types of PSUs currently outstanding: (i) PSUs for which payout is dependent on total shareholder return relative to the S&P 500 Index ("TSR PSUs") and (ii) PSUs for which payout is dependent on the Company's performance against pre-established adjusted cash flow metrics ("Cash Flow PSUs"). Both types of PSUs are payable in shares of common stock after the end of a three-year performance period, when the Company's financial performance for the entire performance period is reported, typically in the first half of the first quarter of the succeeding year. At the end of the performance period, the number of shares awarded can range from 0% to

[**Table of Contents**](#TOC)

#### WASTE MANAGEMENT, INC.

#### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
200% of the targeted amount, depending on the performance against the pre-established targets. A summary of our PSUs, at 100% of the targeted amount, is presented in the table below (units in thousands):

---

| | | |
|:---|:---|:---|
|  | <br>**Units** | **Weighted Average**<br>**Per Share**<br>**Fair Value** |
| Unvested as of January 1, 2025 | 829 | $195.49 |
| Granted | 332 | $277.20 |
| Vested | (263) | $168.48 |
| Forfeited | (24) | $253.07 |
| Unvested as of December 31, 2025 | 874 | $233.05 |

---

The determination of achievement of performance results and corresponding vesting of PSUs for the three-year performance period ended December 31, 2025 was performed by the Management Development and Compensation Committee of our Board of Directors in January 2026. Accordingly, vesting information for such awards is not included in the table above as of December 31, 2025. The "vested" PSUs are for the three-year performance period ended December 31, 2024, as achievement of performance results and corresponding vesting was determined in January 2025. The performance of the Company's common stock for purposes of the TSR PSUs and the Cash Flow PSUs exceeded maximum performance criteria. Accordingly, recipients of the PSU awards received a payout of 167.22% of the vested TSR PSUs and 135.56% of the vested Cash Flow PSUs. In February 2025, approximately 398,000 PSUs vested and we issued approximately 261,000 shares of common stock for these vested PSUs, net of units deferred or used for payment of associated taxes. The shares of common stock that were issued or deferred during the years ended December 31, 2025, 2024 and 2023 for prior PSU award grants had a fair market value of $87 million, $121 million and $74 million, respectively.

PSUs have no voting rights. PSUs receive dividend equivalents that are paid out in cash based on the number of shares that vest at the end of the awards' performance period. Subject to attainment of the performance metrics described above, PSUs are payable to an employee (or applicable beneficiary) upon death or disability as if that employee had remained employed until the end of the performance period. PSUs are generally subject to pro-rata vesting upon an employee's involuntary termination other than for cause and are subject to forfeiture in the event of voluntary or for-cause termination. PSUs generally continue to vest following a qualifying retirement as if the employee had remained employed until the end of the performance period, and compensation expense for PSUs granted to retirement-eligible employees is accelerated over the period that the recipient becomes retirement-eligible plus a defined service requirement.

Compensation expense associated with our Cash Flow PSUs is based on the grant-date fair value of our common stock. Compensation expense is recognized ratably over the performance period based on our estimated achievement of the established performance criteria. Compensation expense is only recognized for those awards that we expect to vest, which we estimate based upon an assessment of both the probability that the performance criteria will be achieved and expected forfeitures. The grant-date fair value of our TSR PSUs is based on a Monte Carlo valuation and compensation expense is recognized on a straight-line basis over the vesting period. Compensation expense is recognized for all TSR PSUs whether or not the market conditions are achieved less expected forfeitures.

*Deferred Units —* Certain employees can elect to defer some or all of the vested RSU or PSU awards for payout six months after the employee leaves the Company. Deferred units are not invested, nor do they earn interest, but deferred amounts do receive dividend equivalents paid in cash during deferral at the same time and at the same rate as dividends on the Company's common stock. Deferred amounts are paid out in shares of common stock at the end of the deferral period. As of December 31, 2025, we had approximately 176,000 vested deferred units outstanding.

*Stock Options —* Stock option awards vest ratably in three annual increments, beginning on the first anniversary of the date of grant. The exercise price of the options is the average of the high and low market value of our common stock

on the date of grant, and the options have a term of 10 years. A summary of our stock options is presented in the table below (options in thousands):

---

| | | |
|:---|:---|:---|
|  | <br>**Options** | **Weighted Average**<br>**Per Share**<br>**Exercise Price** |
| Outstanding as of January 1, 2025 | 2375 | $129.15 |
| Granted | 137 | $231.20 |
| Exercised (a) | (676) | $111.69 |
| Forfeited or expired | (17) | $143.94 |
| Outstanding as of December 31, 2025 (b)  | 1819 | $143.20 |
| Exercisable as of December 31, 2025 (c)  | 1310 | $122.06 |

---

&nbsp;&nbsp;&nbsp;&nbsp;(a) Includes approximately 110,000 stock options exercised pursuant to written trading plans that provided for net share settlement, resulting in the Company withholding approximately 81,000 shares of our common stock to cover the associated stock option exercise price and taxes.

&nbsp;&nbsp;&nbsp;&nbsp;(b) Stock options outstanding as of December 31, 2025 have a weighted average remaining contractual term of 5.6 years and an aggregate intrinsic value of $141 million based on the market value of our common stock on December 31, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;(c) Stock options exercisable as of December 31, 2025 have an aggregate intrinsic value of $128 million based on the market value of our common stock on December 31, 2025.

During 2025, 2024 and 2023, we received cash proceeds of $61 million, $53 million and $44 million, respectively, from the exercise of 676,000, 693,000 and 597,000 of employee stock options. The aggregate intrinsic value of stock options exercised during 2025, 2024 and 2023 was $79 million, $75 million and $44 million, respectively.

Stock options exercisable as of December 31, 2025 were as follows (options in thousands):

---

| | | | |
|:---|:---|:---|:---|
| <br>**Range of Exercise Prices** | <br>**Options** | **Weighted Average**<br>**Per Share**<br>**Exercise Price** | <br>**Weighted Average**<br>**Remaining Years** |
| $56.24 - $98.90 | 436 | $81.95 | 1.9 |
| $98.91 - $145.67 | 593 | $128.34 | 5.2 |
| $145.68 - $231.20 | 281 | $171.05 | 7.6 |
| $56.24 - $231.20 | 1310 | $122.06 | 4.6 |

---

All unvested stock options shall become exercisable upon the award recipient's death or disability. In the event of a recipient's qualifying retirement, stock options shall continue to vest pursuant to the original schedule set forth in the award agreement. If the recipient is terminated by the Company without cause or voluntarily resigns, the recipient shall be entitled to exercise all stock options outstanding and exercisable within a specified time frame after such termination. All outstanding stock options, whether exercisable or not, are forfeited upon termination for cause.

We account for our employee stock options under the fair value method of accounting using a Black-Scholes valuation model to measure stock option expense at the date of grant. The weighted average grant-date fair value of stock options granted during the years ended December 31, 2025, 2024 and 2023 was $47.45, $43.00 and $32.82, respectively. The fair value of stock options at the date of grant is amortized to expense over the vesting period less expected forfeitures, except for stock options granted to retirement-eligible employees, for which expense is accelerated over the period that the

#### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
recipient becomes retirement-eligible. The following table presents the weighted average assumptions used to value employee stock options granted during the year ended December 31 under the Black-Scholes valuation model:

---

| | | | |
|:---|:---|:---|:---|
|  | **2025** | **2024** | **2023** |
| Expected option life | 4.5<br> years | 4.4<br> years | 4.6<br> years |
| Expected volatility | 19.2% | 20.7% | 22.3% |
| Expected dividend yield | 1.4% | 1.5% | 1.9% |
| Risk-free interest rate | 4.2% | 4.2% | 4.4% |

---

The Company bases its expected option life on the expected exercise and termination behavior of its optionees and an appropriate model of the Company's future stock price. The expected volatility assumption is derived from the historical volatility of the Company's common stock over the most recent period commensurate with the estimated expected life of the Company's stock options, combined with other relevant factors including implied volatility in market-traded options on the Company's stock. The expected dividend yield is the annual rate of dividends per share over the exercise price of the option as of the grant date.

For the years ended December 31, 2025, 2024 and 2023, we recognized $154 million, $99 million and $78 million, respectively, of compensation expense associated with RSU, PSU and stock option awards as a component of selling, general and administrative expenses in our Consolidated Statements of Operations. Our income tax expense for the years ended December 31, 2025, 2024 and 2023 includes related income tax benefits of $29 million, $18 million and $15 million, respectively. We have not capitalized any equity-based compensation costs during the reported periods.

As of December 31, 2025, we estimate that $66 million of currently unrecognized compensation expense will be recognized over a weighted average period of 1.5 years for our unvested RSU, PSU and stock option awards issued and outstanding.

#### Non-Employee Director Plan
Our non-employee directors receive annual grants of shares of our common stock under the Incentive Plans described above. Each non-employee director is required to hold all shares issued pursuant to a Company stock award, after the sale of shares necessary to cover applicable taxes, until retirement or other termination of service as a director of the Company.

16. Fair Value Measurements

#### Assets and Liabilities Accounted for at Fair Value
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 Company considers the principal or most advantageous market in which the Company 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 management's estimate of assumptions that market participants would use in pricing the asset or liability.

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. Our assets and liabilities that are measured at fair value on a recurring basis include the following as of December 31 (in millions):

---

| | | |
|:---|:---|:---|
|  | **2025** | **2024** |
| Quoted prices in active markets (Level 1): |  |  |
| &nbsp;&nbsp;Cash equivalents and money market funds | $91 | $56 |
| &nbsp;&nbsp;Equity securities | 88 | 70 |
| Significant other observable inputs (Level 2): |  |  |
| &nbsp;&nbsp;Available-for-sale securities | 528 | 445 |
| &nbsp;&nbsp;&nbsp;&nbsp;Total assets measured at fair value | $707 | $571 |

---

*Cash Equivalents and Money Market Funds*

Cash equivalents primarily include short-term interest-bearing instruments with maturities of three months or less. We invest portions of our restricted trust funds in money market funds and we measure the fair value of these investments using quoted prices in active markets for identical assets. The fair value of our cash equivalents and money market funds approximates our cost basis in these instruments.

*Equity Securities*

We invest portions of our restricted trust funds in equity securities and we measure the fair value of these securities using quoted prices in active markets for identical assets. Any changes in fair value of these securities related to unrealized gains and losses have been appropriately reflected as a component of other, net in our Consolidated Statements of Operations.

[**Table of Contents**](#TOC)

#### WASTE MANAGEMENT, INC.

#### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
*Available-for-Sale Securities*

Our available-for-sale securities include restricted trust funds and investments in unconsolidated entities as discussed in Note 18. We invest primarily in debt securities, including U.S. Treasury securities, U.S. agency securities, municipal securities and mortgage- and asset-backed securities, which generally mature over the next ten years. We measure the fair value of these securities using quoted prices for identical or similar assets in inactive markets. Any changes in fair value of these trusts related to unrealized gains and losses have been appropriately reflected as a component of accumulated other comprehensive income (loss).

#### Fair Value of Debt
As of December 31, 2025 and 2024, the carrying value of our debt was $22.9 billion and $23.9 billion, respectively. The estimated fair value of our debt was approximately $22.5 billion and $22.9 billion as of December 31, 2025 and 2024, respectively.

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 December 31, 2025 and 2024. These amounts have not been revalued since those dates, and current estimates of fair value could differ significantly from the amounts presented.

See Note 11 for information related to our nonrecurring fair value measurements. See Note 17 for information related to the nonrecurring fair value measurement of assets and liabilities acquired in connection with our acquisition of Stericycle.

17. Acquisitions and Divestitures

***Acquisitions***

*2025 Acquisitions* 

During the year ended December 31, 2025, we completed solid waste and recycling acquisitions primarily in Virginia, Maryland and Washington D.C. for total consideration of $440 million. Total consideration included $399 million in net cash paid and $41 million in non-cash consideration, primarily related to purchase price holdbacks. In addition, we paid $9 million of holdbacks, of which $8 million related to prior year acquisitions.

Total consideration for our 2025 acquisitions was primarily allocated to $92 million of property and equipment, $45 million of other intangible assets, primarily customer relationships, and $315 million of goodwill. Other intangible assets included $39 million of customer relationships and $6 million of covenants not-to-compete.

The goodwill related to our 2025 acquisitions was primarily a result of expected synergies from combining the acquired businesses with our existing operations and substantially all was tax deductible.

[**Table of Contents**](#TOC)

#### WASTE MANAGEMENT, INC.

#### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
*2024 Acquisitions* 

In addition to the acquisition of Stericycle, during the year ended December 31, 2024, we completed solid waste and recycling acquisitions primarily in New York, Florida, North Carolina and Arizona for total consideration of $790 million. Total consideration included $783 million in net cash paid and $7 million in non-cash consideration, primarily related to purchase price holdbacks. In addition, we paid $23 million of holdbacks, of which $16 million related to prior year acquisitions.

Total consideration for our 2024 acquisitions, exclusive of Stericycle, was primarily allocated to $160 million of property and equipment, $79 million of other intangible assets and $588 million of goodwill. Other intangible assets included $63 million of customer relationships and $14 million of covenants not-to-compete.

The goodwill related to our other 2024 acquisitions was primarily a result of expected synergies from combining the acquired businesses with our existing operations, a significant portion of which was tax deductible.

In 2024, we paid $41 million to acquire the remaining minority interests in a business engaged in accelerating film and plastic wrap recycling capabilities that is included in our Recycling Processing and Sales segment.

*Stericycle Acquisition —* On June 3, 2024, we entered into an Agreement and Plan of Merger (the "Merger Agreement") to acquire all outstanding shares of Stericycle for $62.00 per share in cash, representing a total enterprise value of approximately $7.2 billion (net of cash acquired) when including the assumption of $0.5 billion of debt and the repayment of approximately $0.8 billion of net debt. The acquisition expands our offerings in the U.S., Canada and parts of Western Europe by providing RWCS and SID services that protect people and brands, promote health and well-being and safeguard the environment. The transaction closed on November 4, 2024 and was funded using $5.2 billion of borrowings under a term credit agreement, our commercial paper program and available cash on hand. Shortly thereafter, we repaid all outstanding borrowings under the term credit agreement with net proceeds from our November 2024 issuance of $5.2 billion of senior notes.

For the year ended December 31, 2025, we incurred acquisition and integration related costs of $120 million, comprised of $89 million of selling, general and administrative costs and $31 million of restructuring costs. For the year ended December 31, 2024, we incurred acquisition and integration related costs of $160 million, which were primarily classified as selling, general and administrative expenses. The post-closing operating results of Stericycle have been included in our consolidated financial statements within our Healthcare Solutions segment. Post-closing through December 31, 2024, Stericycle recognized $403 million, $244 million and $155 million of operating revenue, operating expenses and selling, general and administrative expenses, respectively, which are net of intercompany transactions and included in our Consolidated Statements of Operations.

Our consolidated financial statements have not been retroactively restated to include Stericycle's historical financial position or results of operations. The acquisition was accounted for as a business combination. In accordance with the acquisition method of accounting, the purchase price paid has been allocated to the assets and liabilities acquired based upon their estimated fair values as of the acquisition date, with the excess of the purchase price over the net assets acquired recorded as goodwill. The allocation of the purchase price was finalized in November 2025.

We used the following valuation techniques for the following significant accounts in which carrying value did not approximate fair value: (i) property and equipment were valued primarily using the cost approach with significant assumptions including replacement cost, trend indices, and normal useful lives; (ii) customer relationship assets were valued using the multi-period excess earnings method with significant assumptions including projected revenue, attrition rate, operating expense, selling and general administrative expenses, and discount rate; (iii) indefinite trade name assets were valued using the relief from royalty method with significant assumptions including revenue attributable to the trade names and royalty rates and (iv) permit assets were valued using the cost to recreate method with significant assumptions

[**Table of Contents**](#TOC)

#### WASTE MANAGEMENT, INC.

#### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
including costs required to obtain the permits and the opportunity costs if the permits were not in place on the acquisition date.

The fair values for property and equipment and intangibles were based on significant inputs that are not observable in the market and thus represent a Level 3 measurement in the fair value hierarchy. The Restricted Notes were valued using observable market prices which represent a Level 1 measurement in the fair value hierarchy.

Goodwill of $3.8 billion was calculated as the excess of the consideration paid over the net assets recognized and represents the future economic benefits expected to arise from other assets acquired that could not be individually identified and separately recognized and from synergies of the combination. Goodwill has been assigned to two reporting units within our Healthcare Solutions segment using a relative fair value allocation method. Substantially all of the goodwill is not deductible for income tax purposes.

The following table shows the purchase price allocation as of the date acquired and adjustments made through November 4, 2025 (in millions):

*2023 Acquisitions* 

During the year ended December 31, 2023, we acquired 12 businesses, primarily related to our Collection and Disposal businesses. Total consideration, net of cash acquired, for all acquisitions was $182 million, which included $157 million in net cash paid and $25 million in non-cash consideration, primarily related to purchase price holdbacks. In addition, we paid $13 million of holdbacks, of which $6 million related to prior year acquisitions.

Total consideration for our 2023 acquisitions was primarily allocated to $49 million of property and equipment, $44 million of other intangible assets and $88 million of goodwill. Other intangible assets included $34 million of customer relationships and $10 million of covenants not-to-compete.

The goodwill related to our 2023 acquisitions was primarily a result of expected synergies from combining the acquired businesses with our existing operations and substantially all was tax deductible.

#### Divestitures
Proceeds from divestitures of businesses and other assets, net of cash divested, were $121 million, $158 million and $78 million in 2025, 2024 and 2023, respectively. Proceeds in 2025 primarily related to the January 2025 sale of our Healthcare Solutions segment's Spain and Portugal subsidiaries. As the fair value of consideration transferred was equal to the carrying value of the divested subsidiaries, no gain or loss was recognized. The remaining 2025, 2024, and 2023 proceeds were from the sale of certain non-strategic assets.

18. 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

[**Table of Contents**](#TOC)

#### WASTE MANAGEMENT, INC.

#### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
entities. Our aggregate investment balance in these entities was $624 million and $707 million as of December 31, 2025 and 2024, respectively. The debt balance related to our investments in low-income housing properties was $616 million and $670 million as of December 31, 2025 and 2024, respectively. Additional information related to these investments is discussed in Note 8.

#### 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 other long-term assets in our 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 income (loss). Our investments and receivables related to these trusts had an aggregate carrying value of $127 million and $111 million as of December 31, 2025 and 2024, 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 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 $140 million and $128 million as of December 31, 2025 and 2024, respectively.

19. Segment and Related Information

Our senior management evaluates, oversees and manages the financial performance of our business through five reportable segments, referred to as (i) East Tier; (ii) West Tier; (iii) Recycling Processing and Sales; (iv) Renewable Energy and (v) Healthcare Solutions. Our East and West Tiers, along with Other Ancillary services, form our "Collection and Disposal" businesses. We also provide additional services not managed through our five reportable segments, which are presented as Corporate and Other.

From time to time, our operating results are significantly affected by certain transactions or events that management believes are not indicative or representative of our results. Refer to Note 11 for an explanation of certain transactions and events affecting our operating results. Reclassifications have been made to our prior period consolidated financial information to conform to the current year presentation.

***Collection and Disposal***

Our Collection and Disposal businesses provide integrated environmental services, including collection, transfer, disposal and resource recovery services. We evaluate our Collection and Disposal businesses primarily through two geographic segments, East Tier and West Tier. 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, Southern and Central U.S., including the upper Midwest region, and British Columbia, Canada. Additionally, we provide Other Ancillary services that are not managed through the Tier segments but that support our collection and disposal operations. Other Ancillary includes specialized services performed for customers that have differentiated needs. These specialized services are targeted at large industrial customers managed through our Sustainability and Environmental Solutions ("SES") business or geographically dispersed customers managed through our Strategic Business Solutions ("WMSBS") business. Also included within Other Ancillary are the results of non-operating entities that provide financial assurance and self-insurance support for our business, net of intercompany activity.

[**Table of Contents**](#TOC)

#### WASTE MANAGEMENT, INC.

#### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
Included within our Collection and Disposal businesses are landfills having (i) 19 third-party power generating facilities converting our landfill gas to fuel electricity generators; (ii) 17 third-party RNG facilities processing landfill gas to be sold to natural gas suppliers and (iii) nine third-party projects delivering our landfill gas by pipeline to industrial customers as a direct substitute for fossil fuels in industrial processes. In return for providing our landfill gas, we receive royalties from each facility, including the benefit of a 15% royalty from our Renewable Energy segment based on net operating revenue generated through the sale of RNG, RINs, electricity and capacity, RECs and related environmental attributes from the 86 landfill beneficial use renewable energy projects owned by Renewable Energy on our active landfills, which is eliminated in consolidation.

***Recycling Processing and Sales***

Our Recycling Processing and Sales segment includes the processing and sales of materials collected from residential, commercial and industrial customers. The materials are delivered to and processed at one of our many recycling facilities. Through our brokerage business, we also manage the marketing of recycling commodities that are processed in our facilities and by third parties by maintaining comprehensive service centers that continuously analyze market prices, logistics, market demands and product quality. Our Recycling Processing and Sales segment excludes the collection of recycled materials from our residential, commercial, and industrial customers which is included within our Collection and Disposal businesses.

***Renewable Energy***

Our Renewable Energy segment develops, operates and promotes projects for the beneficial use of landfill gas. Landfill gas is produced naturally as waste decomposes in a landfill. The methane component of the landfill gas is a readily available, renewable energy source that can be gathered and used beneficially as an alternative to fossil fuel. Renewable Energy converts landfill gas into several sources of renewable energy which include RNG, electricity and capacity, heat and/or steam. Renewable Energy also generates RINs under the RFS program, other credits under a variety of state programs associated with the use of RNG in our compressed natural gas fleet and RECs associated with the production of electricity. The RINs, RECs, and other credits are sold to counterparties who are obligated under the regulatory programs and have a responsibility to procure RINs, RECs and other credits proportionate to their fossil fuel production and imports. RINs and RECs prices generally fluctuate in response to regulations enacted by the EPA or other regulatory bodies, as well as changes in supply and demand.

As of December 31, 2025, we had 103 landfill gas beneficial use projects producing commercial quantities of methane gas at owned or operated landfills. For 62 of these projects, the processed gas is used to fuel electricity generators. The electricity is then sold to public utilities, municipal utilities or power cooperatives. For 24 of these projects, the gas is used at the landfill or delivered by pipeline to industrial customers as a direct substitute for fossil fuels in industrial processes. For 17 of these projects, the landfill gas is processed to pipeline quality RNG and then sold to natural gas suppliers. Additionally, three projects are on third-party landfills. The revenues from these facilities are primarily generated through the sale of RNG, RINs, electricity and capacity, heat and/or steam, RECs and related environmental attributes. Renewable Energy is charged a 15% royalty on net operating revenue from these facilities residing on our active and closed landfills from our Collection and Disposal and Corporate and Other businesses, which is eliminated in consolidation. Additionally, Renewable Energy operates and maintains six third-party landfill beneficial gas use projects in return for service revenue. Our Collection and Disposal and Corporate and Other businesses benefit from these projects as well as 54 additional third-party landfill beneficial gas use projects in the form of royalties.

***Healthcare Solutions***

Our Healthcare Solutions segment includes (i) RWCS, which provide compliance programs and collection, processing and disposal of regulated and specialized waste, including medical, pharmaceutical and hazardous waste and (ii) SID

[**Table of Contents**](#TOC)

#### WASTE MANAGEMENT, INC.

#### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
services, which provide for the collection of personal and confidential information for secure destruction and recycling of sorted office paper. RWCS are provided to customers in the U.S., Canada, Ireland and the United Kingdom ("U.K."). SID services are provided to customers in the U.S., Canada, Belgium, France, Germany, Ireland, Luxembourg, the Netherlands and the U.K.

Our Healthcare Solutions customers are primarily in the following industries: enterprise healthcare (i.e., hospitals, health systems and national and corporate healthcare), practices and care providers (i.e., physician offices, surgery centers, veterinary clinics, nursing and long-term care facilities, dental clinics, clinics and urgent care, dialysis centers and home health organizations), and pharmacy labs and research centers. Our Healthcare Solutions businesses also provide services to airports and seaports, education institutions, funeral homes and crematories, government and military, banks and professional services, and other businesses. While the Healthcare Solutions businesses manage large volumes of waste and other materials, the average volume per customer site is relatively small.

Our Healthcare Solutions customers typically enter into a contract for the provision of services on a scheduled basis including weekly, monthly or on an as-needed basis over the contract term. Under the contract terms, the Healthcare Solutions businesses receive fees based on a monthly, quarterly or annual rate and/or fees based on contractual rates depending upon measures including the type and volume or weight of waste. Operating revenues are invoiced based on the terms of the underlying contract either on a regular basis, or as services are performed and are generally due within a short period of time after invoicing based upon normal terms and conditions for our business type and the geography of the services performed.

As of December 31, 2025, our Healthcare Solutions segment operates out of approximately 307 leased and owned facilities worldwide with 51 autoclaves or other alternative medical waste treatment facilities, 17 medical waste incinerator facilities, 99 SID processing facilities, and 140 transfer stations.

***Corporate and Other***

We also provide additional services that are not managed through our operating segments, which are presented in this report as Corporate and Other as they do not meet the criteria to be aggregated with other operating segments and do not meet the quantitative criteria to be separately reported. This includes the activities of our corporate office, including costs associated with our long-term incentive program, expanded service offerings and solutions (such as our investments in businesses and technologies that are designed to offer services and solutions ancillary or supplementary to our current operations) as well as our closed sites. Also, included within our Corporate and Other businesses closed sites are (i) five third-party power generating facilities converting our landfill gas to fuel electricity generators; (ii) two third-party projects delivering our landfill gas by pipeline to industrial customers as a direct substitute for fossil fuels in industrial processes and (iii) two third-party RNG facilities processing landfill gas to be sold to natural gas suppliers in return for a royalty. Additionally, Corporate and Other benefits from a 15% royalty from our Renewable Energy segment based on net operating revenue generated through the sale of RNG, RINs, electricity and capacity, RECs and related environmental attributes from the 17 landfill beneficial use renewable energy projects owned by Renewable Energy on our closed sites, which is eliminated in consolidation.

Our chief operating decision maker ("CODM") is the chief executive officer. The CODM regularly reviews financial results, operating performance, and capital expenditures of our five reportable segments. Our CODM uses income from operations for each segment predominantly in the annual budget and forecasting process and considers budget-to-actual variances on a monthly basis when making decisions about the allocation of operating and capital resources to each segment. Our CODM also uses segment income from operations to assess the performance of each segment by comparing the results of each segment with one another. Summarized financial information concerning our reportable segments as of December 31 and for the year then ended is shown in the following table (in millions):

&nbsp;&nbsp;&nbsp;&nbsp;(c) For those items included in the determination of income from operations, the accounting policies of the segments are the same as those described in Note 2.

&nbsp;&nbsp;&nbsp;&nbsp;(d) Includes non-cash items. Additionally, our Corporate and Other business recognizes construction work in progress for fleet purchases during the period. Capital expenditures are reported in our reportable segments at the time they are recorded within the segments' property and equipment balances and, therefore, include timing differences for amounts accrued but not yet paid as well as amounts transferred from Corporate and Other for fleet placed in service.

&nbsp;&nbsp;&nbsp;&nbsp;(e) Certain fees related to the processing of recyclable material we collect are included within our Collection and Disposal businesses. The amounts in income from operations for the years ended December 31, 2025, 2024 and 2023 are $75 million, $100 million and $61 million, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;(f) Renewable Energy pays a 15% intercompany royalty to our Collection and Disposal and Corporate and Other businesses for landfill gas. The total amount of royalties in gross and intercompany operating revenues for the East Tier, West Tier, and Corporate and Other and in operating expenses for Renewable Energy for the years ended December 31, 2025, 2024 and 2023 are $72 million, $48 million and $41 million, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;(g) Our Collection and Disposal business records intercompany operating revenue for collection and disposal services provided to Healthcare Solutions. The total amount of intercompany operating revenues reflected in our Collection and Disposal businesses and in operating expenses for Healthcare Solutions for the years ended December 31, 2025 and 2024, are $55 million and $8 million, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;(h) In the third quarter of 2025, as a result of continued integration efforts and to enhance transparency and accountability, the Company began reflecting intra-segment activity within the Healthcare Solutions segment. These charges were designed to measure profitability at more granular levels of the enterprise and to facilitate clearer financial accountability within operating units. Accordingly, adjustments to the years ended December 31, 2025 and 2024 activity were made to properly reflect intra-segment activity for both periods. Intra-segment operating revenues and operating expenses within Healthcare Solutions for the years ended December 31, 2025 and 2024 are $425 million and $58 million, respectively.

Total assets by reportable segment as of December 31 are as follows (in millions):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Includes each segment's intercompany activity, including transactions 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.

Our financial and operating results may fluctuate for many reasons, 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 operating revenues and volumes typically experience seasonal increases in the summer months that are reflected in second and third quarter revenues and results of operations.

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.

Net operating revenues relating to operations for the year ended December 31 are as follows (in millions):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) 2025 and 2024 primarily relates to the impact of operations from the U.K., Ireland, Belgium, France, Germany, Luxembourg, and the Netherlands as a result of the November 2024 Stericycle acquisition.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) 2023 primarily relates to an acquired smaller recycling-related operations in the Netherlands .

#### Item 9.&nbsp;&nbsp;&nbsp;&nbsp; Changes in and Disagreements with Accountants on Accounting and Financial Disclosure.
None.

#### Item 9A.&nbsp;&nbsp;&nbsp;&nbsp; Controls and Procedures.

#### Effectiveness of Disclosure Controls and Procedures
Our management, with the participation of our principal executive and financial officers, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended) in ensuring that the information required to be disclosed in reports that we file or submit under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, including ensuring that such information is accumulated and communicated to management (including the principal executive and financial officers) as appropriate to allow timely decisions regarding required disclosure. Based on such evaluation, our principal executive and financial officers have concluded that such disclosure controls and procedures were effective as of December 31, 2025 (the end of the period covered by this Annual Report on Form 10-K) at a reasonable assurance level.

#### Management's Report on Internal Control Over Financial Reporting
Management of the Company, including the principal executive and financial officers, is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) of the Securities Exchange Act of 1934, as amended. Our management conducted an evaluation of the effectiveness of our internal control over financial reporting based on the 2013 framework in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Our internal controls are designed to provide reasonable assurance as to the reliability of our financial reporting and the preparation of the consolidated financial statements for external purposes in accordance with accounting principles generally accepted in the United States and includes those policies and procedures that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i. pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii. provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iii. provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management of the Company assessed the effectiveness of our internal control over financial reporting as of December 31, 2025 based on the 2013 framework in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Based on this assessment, management has concluded that our internal control over financial reporting was effective as of December 31, 2025.

The effectiveness of our internal control over financial reporting has been audited by Ernst & Young LLP, the independent registered public accounting firm that audited our consolidated financial statements, as stated in their report, which is included in Item 8 of this Annual Report on Form 10-K.

[**Table of Contents**](#TOC)

#### Changes in Internal Control over Financial Reporting
Management, together with our CEO and CFO, evaluated the changes in our internal control over financial reporting during the quarter ended December 31, 2025. During this period, we completed the integration of the internal control over financial reporting of Stericycle, which we acquired in November 2024 and is now referred to herein as our Healthcare Solutions business, with the Company's overall internal control over financial reporting process. Other than this integration, management determined that there were no changes in our internal control over financial reporting during the quarter ended December 31, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

\* Only these series of Senior Notes do not contain a Change of Control Offer covenant. Such covenant provides that, if a change of control triggering event occurs, each holder of the notes may require us to purchase all or a portion of such holder's notes at a price equal to 101% of the principal amount, plus accrued interest, if any, to the date of purchase.

\*\* On June 25, 2025, we completed an exchange offer pursuant to which we issued approximately $483 million in new notes (the "Registered Notes") registered under the Securities Act of 1933, as amended, in exchange for a like amount of our outstanding unregistered 3.875% Senior Notes due 2029 (the "Restricted Notes"). This amount represented approximately 99% of the $485 million aggregate principal amount of Restricted Notes that were originally issued on November 8, 2024, in a private offer in exchange for notes of Stericycle, Inc. The terms of the Registered Notes are substantially identical in all material respects to the terms of the Restricted Notes, except that the Registered Notes are not subject to restrictions on transfer. The portion of Restricted Notes not exchanged remains an outstanding obligation and is not a material debt obligation of Waste Management, Inc.

This schedule is provided in accordance with Instruction 2 to Regulation S-K Item 601, as each of the series of Senior Notes, other than the WM Notes, is governed by an instrument that differs only in the material respects set forth in the schedule above from the Officers' Certificate identified as Exhibit 4.8 to this Form 10-K. Each of the series of Senior Notes identified above is also guaranteed by Waste Management Holdings, Inc. in favor of The Bank of New York Mellon Trust Company, N.A., as Trustee for the holders of Waste Management, Inc.'s Senior Notes.

## Ex-95

**Exhibit 95**

**Mine Safety Disclosures** 

This exhibit contains certain specified disclosures regarding mine safety required by section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of Regulation S-K. Certain of our subsidiaries have permits for surface mining operations that are incidental to excavation work for landfill development.

During the year ended December 31, 2025, we did not receive any of the following: (a) a citation from the U.S. Mine Safety and Health Administration ("MSHA") for a violation of mandatory health or safety standards that could significantly and substantially contribute to the cause and effect of a coal or other mine safety or health hazard under section 104 of the Federal Mine Safety and Health Act of 1977 (the "Mine Safety Act"); (b) an order issued under section 104(b) of the Mine Safety Act; (c) a citation or order for unwarrantable failure of the mine operator to comply with mandatory health or safety standards under section 104(d) of the Mine Safety Act; (d) a flagrant violation under section 110(b)(2) of the Mine Safety Act; (e) an imminent danger order under section 107(a) of the Mine Safety Act or (f) a proposed assessment from the MSHA.

In addition, during the year ended December 31, 2025, we had no mining-related fatalities, we had no pending legal actions before the Federal Mine Safety and Health Review Commission involving a coal or other mine, and we did not receive any written notice from the MSHA involving a pattern of violations, or the potential to have such a pattern, of mandatory health or safety standards that are of such nature as could have significantly and substantially contributed to the cause and effect of coal or other mine health or safety hazards under section 104(e) of the Mine Safety Act.
