customers’ needs quickly in a cost-effective manner. We believe that decentralization provides a low-overhead, highly efficient operational structure that allows us to expand into geographically contiguous markets and operate in relatively small communities that larger competitors may not find attractive. We believe that this structure gives us a strategic competitive advantage, given the relatively rural nature of many of the markets in which we operate, and makes us an attractive buyer to many potential acquisition candidates.

We manage and evaluate our business on the basis of the operating segments’ geographic characteristics, interstate waste flow, revenue base, employee base, regulatory structure, and acquisition opportunities. Each operating segment has a regional vice president and a regional controller reporting directly to our corporate management. These regional officers are responsible for operations and accounting in their operating segments and supervise their regional staff. See Note 17 to the consolidated financial statements included in Item 8 of this Annual Report on Form 10-K for further information on our segment reporting of our operations.

Each operating location has a district or site manager who has a high degree of decision-making authority for his or her operations and is responsible for maintaining service quality, promoting safety, implementing marketing programs and overseeing day-to-day operations, including contract administration. Local managers also help identify acquisition candidates and are responsible for integrating acquired businesses into our operations and obtaining the permits and other governmental approvals required for us to operate.

Implement Operating Standards. We develop company-wide operating standards, which are tailored for each of our markets based on industry norms and local conditions. We implement cost controls and employee training and safety procedures and establish a sales and marketing plan for each market. By internalizing the waste stream of acquired operations, we can further increase operating efficiencies and improve capital utilization. We use a wide-area information system network, implement financial controls and consolidate certain accounting, personnel and customer service functions. While regional and district management operate with a high degree of autonomy, our executive officers monitor regional and district operations and require adherence to our accounting, purchasing, safety, marketing, legal and internal control policies, particularly with respect to financial matters. Our executive officers regularly review the performance of regional officers, district managers and operations. We believe we can improve the profitability of existing and newly acquired operations by establishing operating standards, closely monitoring performance and streamlining certain administrative functions.

Our Growth Strategy

We tailor the components of our growth strategy to the markets in which we operate and into which we hope to expand.

Obtain Additional Exclusive Arrangements. Our operations include market areas where we have exclusive arrangements, including franchise agreements, municipal contracts and governmental certificates, under which we are the exclusive service provider for a specified market. These exclusive rights and contractual arrangements create a barrier to entry that is usually obtained through the acquisition of a company with such exclusive rights or contractual arrangements or by winning a competitive bid.

We devote significant resources to securing additional franchise agreements and municipal contracts through competitive bidding and by acquiring other companies. In bidding for franchises and municipal contracts and evaluating acquisition candidates holding governmental certificates, our management team draws on its experience in the waste industry and knowledge of local service areas in existing and target markets. Our district management and sales and marketing personnel maintain relationships with local governmental officials within their service areas, maintain, renew and renegotiate existing franchise agreements and municipal contracts, and secure additional agreements and contracts while targeting acceptable financial returns. Our sales and marketing personnel also expand our presence into areas adjacent to or contiguous with our existing markets, and market additional services to existing customers. We believe our ability to offer comprehensive rail haul disposal services in the Pacific Northwest improves our competitive position in bidding for such contracts in that region.

Generate Internal Growth. To generate internal revenue growth, our district management and sales and marketing personnel focus on increasing market penetration in our current and adjacent markets, soliciting new customers in markets where such customers have the option to choose a particular waste collection service and marketing upgraded or additional services (such as compaction or automated collection) to existing customers. We also seek price increases necessary to offset increased costs, to improve operating margins and to obtain adequate returns on our deployed capital. Where possible, we intend to leverage our franchise-based platforms to expand our customer base beyond our exclusive market territories. As customers are added in existing markets, our revenue per routed truck increases, which generally increases our collection efficiencies and profitability. In markets in which we have exclusive contracts, franchises and governmental certificates, we expect internal volume growth generally to track population and business growth.

Expand Through Acquisitions. We intend to expand the scope of our operations by continuing to acquire waste businesses in new markets and in existing or adjacent markets that are combined with or “tucked-in” to our existing operations. We focus our acquisition efforts on markets that we believe provide significant growth opportunities for a well-capitalized market entrant and where we can compete efficiently with potential new competitors. This focus typically highlights markets in which we can:  (1) provide waste collection services under exclusive arrangements such as franchise agreements, municipal contracts and governmental certificates; (2) gain a leading market position and provide vertically integrated collection and disposal services; or (3) gain a leading market position in a niche market through the provision of treatment and disposal services. We believe that our experienced management, decentralized operating strategy, financial strength, size and public company status make us an attractive buyer to certain waste collection and disposal acquisition candidates. We have developed an acquisition discipline based on a set of financial, market and management criteria to evaluate opportunities. Once an acquisition is closed, we seek to integrate it while minimizing disruption to our ongoing operations and those of the acquired business.

In new markets, we often use an initial acquisition as an operating base and seek to strengthen the acquired operation’s presence in that market by providing additional services, adding new customers and making “tuck-in” acquisitions of other waste companies in that market or adjacent markets. We believe that many suitable “tuck-in” acquisition opportunities exist within our current and targeted market areas that may provide us with opportunities to increase our market share and route density.

The North America solid waste services industry has experienced continued consolidation over the past several years, most notably with the acquisition of Advanced Disposal Services, Inc. by Waste Management, Inc. in October 2020 and our acquisition of Progressive Waste (as defined below) in June 2016. In spite of this consolidation, the solid waste services industry remains regional in nature, with acquisition opportunities available in select markets. In some markets in both municipal solid waste, or MSW, and E&P waste, independent landfill, collection or service providers lack the capital resources, management skills and/or technical expertise necessary to comply with stringent environmental and other governmental regulations and to compete with larger, more efficient, integrated operators. In addition, many of the remaining independent operators may wish to sell their businesses to achieve liquidity in their personal finances or as part of their estate planning.

During the year ended December 31, 2021, we completed 30 acquisitions for consideration having a net fair value of $1.069 billion. During the year ended December 31, 2020, we completed 21 acquisitions for consideration having a net fair value of $481.6 million. During the year ended December 31, 2019, we completed 21 acquisitions for consideration having a net fair value of $837.7 million.

HUMAN CAPITAL

We believe that people are our greatest differentiator. We aim to be an employer of choice that attracts and retains high performing talent with the mindset, skillset and commitment to uphold our values of safety, integrity, customer service, being a great place to work and the premier solid waste services company in the U.S. and Canada. Our goal is to create an environment where self-directed, empowered employees strive to consistently fulfill our constituent commitments and seek to create positive impacts through interactions with customers, communities and fellow employees, always relying on our Operating Values as the foundation for our existence.  All employees are responsible for upholding the Waste Connections Vision and Values, and the Waste Connections Code of Conduct, which form the foundation of our policies and practices. Moreover, we are committed to an inclusive, supportive environment built on the principles of

Servant Leadership, valuing diversity and inspiring employee growth.  As such, developing our talent and maintaining our culture through employee engagement are integral to the growth and sustainability of our business.

Our Workforce

As of December 31, 2021, our employee population consisted of 19,998 active employees, 10,322 of whom are commercial truck drivers and 1,663 of whom are mechanics. There were 17,146 employees located in the United States and 2,852 employees located in Canada.  38.6% of those employees are ethnic minorities, 16.4% are women, and 8% are from the armed services.  

As of December 31, 2021, 2,934 employees, or approximately 15% of our workforce, were employed under collective bargaining agreements. The majority of our collective bargaining agreements are with the Teamsters Union in both the U.S. and Canada. These collective bargaining agreements are renegotiated periodically. In 2021, we did not experience any work stoppages or have any days idle as a result of labor issues.  We have 22 collective bargaining agreements covering 1,053 employees that have expired or are set to expire during 2022. We do not expect any significant disruption in our overall business in 2022 as a result of labor negotiations, employee strikes or organizational efforts by labor unions or their representatives.  

COVID-19-Related Employee Support

Since the onset of the pandemic of coronavirus disease 2019, or COVID-19, protecting the health, safety and welfare of our employees has been our top priority. In order to support and protect our employees, we established protocols and implemented operational changes focused on the health and safety of our frontline employees and accommodated transitions to remote work environments for customer service representatives and other support personnel. In addition, recognizing the potential for financial hardship and other challenges, we looked to provide a safety net for our employees on issues of income and family health.

To that end, since the onset of the pandemic and through the end of 2021, we have incurred over $40 million in incremental COVID-19-related costs, primarily supplemental pay for frontline employees.  This included bonus payments as well as supplemental wages, which were provided to all frontline employees, whether union or non-union, remote or on-site, as well as temporary workers. We provided full base wages for employees feeling ill, under quarantine, or caring for family members, and two-thirds of base wages for up to 12 weeks for those with childcare needs.  We also expanded our Employee Relief Fund for those experiencing financial hardship, launched the Waste Connections Scholarship Program to assist our employees’ children in pursuing their educational goals, covered COVID-19-related testing and medical costs, and expanded and extended access to medical benefits.

In addition to our COVID-19-related financial commitments, in 2020 we proactively raised our minimum hourly wage target to $15 per hour (CAD $16 per hour in Canada), exceeding many state, provincial and local wage requirements. Looking beyond our people, we also recognized the needs of the communities where we live and work, increasing the level of charitable contributions to assist food banks, families at risk, and organizations with a focus on addressing racial inequities at a local or national level, providing meals for healthcare workers and higher risk populations, and donating critical personal protective equipment. In 2021, we maintained the higher levels of community support as we continued to focus on the well-being of our employees and the communities we serve, encouraging vaccinations, providing test kits, and complying with federal, state, provincial and local laws that required vaccination tracking, case reporting and testing for all unvaccinated employees.    

Safety

Safety is our first operating value at Waste Connections.  We are committed to the safety of our employees, customers, and the communities we serve.  Our ultimate goal is to “Drive to ZERO”, that is, to achieve zero incidents and accidents. Our success in safety is driven by our self-directed and empowered employees taking personal ownership for their safety and the safety of those around them.  As servant leaders, we endeavor every day to protect our employees and the communities we are privileged to work in and around. We utilize on-board event recording technology to identify both risky behavior, which is coached, and best practices, which are reinforced and rewarded with safety bonuses.  We have

developed a risk-based scoring system for our drivers to improve their safe driving skills and hold our leaders responsible for the performance of the employees they are privileged to serve.

In 2021, this behavior-based approach to safety resulted in over 56% of our operating locations posting zero safety-related incidents or reduced incident frequency over the prior year.  We maintained the 12% reduction in our incident rate that we achieved in 2020, in spite of factors including: the reopening of the economy, driving greater mobility and heavier traffic; increased employee turnover; and an outsized year of acquisitions, which have typically operated with higher incident rates than our corporate average.  After adjusting for acquisitions completed during the year, we experienced continued improvement in our incident rate in 2021.

Safety training is an integral part of our culture of safety.  To reinforce safe driving skills and safe work practices throughout Waste Connections, we require both initial training for all new driver employees and reinforcement training each year.  Areas of focus in training include: “Target 4” defensive driving, Smith System driving fundamentals, Injury & Illness prevention, and Safe Work Practices training.  We further emphasize the importance of safety through regular tailgate safety meetings and rollout safety instructions for our drivers, and through the utilization of electronic safety communication boards, safety alerts, and other communications to heighten awareness and maintain focus every day on the importance of safety.  

While we attribute our successful safety record to our culture and behavior-based approach, we recognize that advances in fleet design and technology can be important tools in identifying risky behaviors and providing coaching opportunities to further our efforts to achieve our long-term aspirational target of a 25% reduction in incident rates as described in our 2021 Sustainability Report (www.wasteconnections.com/sustainability). To that end, in 2021, we continued implementation of a $10 million fleet-wide upgrade of our on-board event recording technology initiated in 2020, adding Machine Vision and Artificial Intelligence to identify at-risk behaviors, with completion of the rollout anticipated in 2022.  We also deployed additional Freightliner EconicSD trucks with an overhauled cab design that incorporates many of the safety features already standard in passenger vehicles, as well as an integrated collision mitigation system, enhanced visibility, and several ergonomic improvements.  

Culture/Servant Leadership

At Waste Connections, we maintain that our purposeful culture drives differentiated results; therefore, investing in our people is a priority as we employ an approach guided by Servant Leadership. This concept inverts the traditional management hierarchy, positioning leaders to serve their employees both professionally and personally. The philosophy empowers employees by prioritizing their needs, sharing responsibility and driving personal development.  As a result, a significant amount of management time and resources are dedicated to leadership training and development.

Training and Development

Our leadership development efforts focus on multi-day Servant Leadership training sessions, in which approximately 24% of our leadership team participated in 2021 in spite of the limitations on in-person training as a result of COVID-19-related travel restrictions.  These leadership training sessions, generally conducted in-person but also available online, are developed and administered by dedicated internal resources and also include participation by the senior leadership team.

In addition, the Company provides a broad range of other training and on-the-job learning opportunities, including district management training, varying leadership webinar topics, and other safety, sales, maintenance, operations and financial training courses engaging every level of employee throughout the Company.  In 2021, we added a retention-focused program called “Rethinking Retention” to our leadership training and development efforts with a focus on skills in key areas that influence employee tenure.

Through our Learning Management System (“LMS”), we track employee progress and can utilize the LMS to share new course topics and additional content.  We continued to expand training opportunities available to our employees and increased the number of sessions offered by over 18% in 2021 from the prior year, with approximately 63% of all employees participating in either a virtual or in-person training.

Employee Pay and Benefits

We strive to make Waste Connections a great place to work. Our approach to attracting safe, productive workers includes a focus on providing full time, stable, local jobs with competitive pay and benefits.  

Our pay and benefits strategy is designed to provide programs and services that help meet the varying needs of our employees, particularly during challenging periods like the COVID-19 pandemic, when we increased our targeted minimum wage to $15 per hour (CAD $16 per hour in Canada) and introduced the Waste Connections Scholarship Program, in addition to providing discretionary supplemental pay and benefits, including expanded access to our Employee Relief Fund. Our total rewards package for frontline employees includes market-competitive pay, bonus opportunities, affordable and comprehensive healthcare plans, market-leading retirement benefits, generous and flexible time off plans, and the opportunity to share in the Company’s success through an Employee Share Purchase Plan.  Our leaders also are eligible for incentive compensation programs consisting of an annual cash bonus, equity, or both, dependent on their contributions to improving safety, financial results, and key human capital measures like turnover, employee development and employee survey scores.  

Employee Engagement

Beyond compensation and benefits, we believe employee engagement includes increased investments in training and development of our leaders and frontline employees, and innovating new technology offerings to increase connectivity both inside and outside of the Company. We also recognize the importance of engagement in driving culture and increasing retention, which was magnified in 2020, when the COVID-19 pandemic necessitated the use of remote alternatives to in-person training and development and highlighted the importance of connectivity both inside and outside of the Company.  In response, we launched Workplace, our internal, mobile-friendly collaborative software platform that allows all employees, employee resource groups and leaders to share a steady stream of news and stories to connect, inform and further increase employee engagement.  

We conduct an annual Servant Leadership survey, which provides employees the opportunity to evaluate their managers on an anonymous basis and provide written feedback. We target continuous improvement in the scores as an element of the long-term aspirational goals included in our 2021 Sustainability Report.  In 2021, we experienced continued improvement in our managers’ Servant Leadership scores, with an employee response rate of over 85%.

Diversity and Inclusion

We are committed to building and developing diverse teams that function in an environment of mutual respect, where employees feel valued, empowered to contribute and positioned for success.  

In keeping with our efforts to support and encourage diversity and inclusion, we have undertaken several initiatives, including adopting in 2019 a formal Diversity Policy for our Board of Directors and Senior Management with aspirational targets for female Board representation, and additional disclosure on workforce composition.  Since that time, we’ve incorporated diversity and inclusion into Servant Leadership training, expanded our annual Servant Leadership assessments of our managers by employees to incorporate a diversity and inclusion score, and introduced a monthly educational program focused on diversity and inclusion that is available to all employees through our LMS with additional discussion tools provided to our leadership team.  We’ve also enhanced recruiting practices to ensure the broadest candidate pools, established financial commitments to organizations that focus on racial inequities and that support women and children at risk, and supported the development of resource groups including our Women’s Network and Veterans’ S.E.R.V.E. Network.  Waste Connections is a signatory to the CEO Action for Diversity & Inclusion, the largest CEO-driven business commitment to advance diversity and inclusion within the workplace.

Employee Recruiting

In 2021, we hired 5,806 employees through our network of internal recruiters operating on a divisional and regional basis. Our internal recruiting team endeavors to not only fill open positions, but to partner with hiring managers to continuously improve our efforts with respect to marketing, screening, interviewing, onboarding and employee retention.

Table of Contents

In addition to recruiting locally in the communities we serve, we use job fairs, open house events, employee referral programs, social media channels, local radio and television advertising, and school to work partnerships.  Our job opportunities are hosted on www.careers.wasteconnections.com, posted on www.indeed.com, www.linkedin.com, as well as state and provincial job boards, and syndicated to expand our reach to dozens of diversity-oriented and military-focused recruiting websites such as www.honorher.works, www.jobs.vetjobs.org, www.diversity.dejobs.org, www.enableamerica.dejobs.org and www.campuspride.jobs.

SUSTAINABILITY/ENVIRONMENTAL SOCIAL AND GOVERNANCE, OR ESG

Environmental, organizational and financial sustainability initiatives have been key components of our success since we were founded in 1997. We continuously monitor and evaluate new technologies and investments that can enhance our commitment to the environment, to our employees and to the communities we serve.  These investments align with our focus on value creation for all stakeholders and we remain committed to expanding these efforts as our industry and technology continue to evolve. To that end, in 2020 we made a $500 million commitment to the advancement of the long-term aspirational targets outlined in our 2021 Sustainability Report.  

These targets include reducing environmental impact through expanded resource recovery capacity, increased landfill gas recovery and development of new renewable natural gas facilities, and increased on-site leachate treatment at our landfills. In addition, they focus on enhancing employee safety and engagement through reducing safety incident rates, continuous improvement in voluntary turnover, and increased Servant Leadership scores. Moreover, in 2021, we incorporated these ESG targets into executive compensation metrics.

We recognize the importance of disclosure surrounding these initiatives and strive to become increasingly transparent through the continued use and adoption of new ESG frameworks, expansion of ESG-related data points, as well as participation at ESG-related industry events and other investor engagements.

WASTE SERVICES

Collection Services

We provide collection services to residential, commercial, municipal, industrial and E&P customers. Our services are generally provided under one of the following arrangements:  (1) governmental certificates; (2) exclusive franchise agreements; (3) exclusive municipal contracts; (4) residential subscriptions; (5) residential contracts; or (6) commercial, industrial and E&P service agreements.

Governmental certificates, exclusive franchise agreements and exclusive municipal contracts grant us rights to provide MSW services within specified areas at established rates and are long-term in nature. Governmental certificates, or G Certificates, are unique to the State of Washington and are awarded by the Washington Utilities and Transportation Commission, or WUTC, to solid waste collection service providers in unincorporated areas and electing municipalities. These certificates typically grant the holder the exclusive and perpetual right to provide specific residential, commercial and/or industrial waste services in a defined territory at specified rates, subject to divestiture and/or overlap or cancellation by the WUTC on specified, limited grounds. Franchise agreements typically provide an exclusive period of seven years or longer for a specified territory; they specify a broad range of services to be provided, establish rates for the services and can give the service provider a right of first refusal to extend the term of the agreement. Municipal contracts typically provide a shorter service period and a more limited scope of services than franchise agreements and generally require competitive bidding at the end of the contract term. In markets where exclusive arrangements are not available, we may enter into residential contracts with homeowners’ associations, apartment owners and mobile home park operators, or work on a subscription basis with individual households. In such markets, we may also provide commercial and industrial services under customer service agreements generally ranging from one to five years in duration. Finally, in certain E&P markets with “no pit” rules or other regulations that limit on-site storage or treatment of waste, we offer containers and collection services to provide a closed loop system for the collection of drilling wastes at customers’ well sites and subsequent transportation of the waste to our facilities for treatment and disposal.

Landfill Disposal Services

As of December 31, 2021, we owned or operated 71 MSW landfills, 12 E&P waste landfills, which only accept E&P waste and 14 non-MSW landfills, which only accept construction and demolition, industrial and other non-putrescible waste. Eight of our MSW landfills also received E&P waste during 2021. We generally own landfills to achieve vertical integration in markets where the economic and regulatory environments make landfill ownership attractive. We also own landfills in certain markets where it is not necessary to provide collection services because we believe that we are able to attract volume to our landfills, given our location or other market dynamics.

For landfills we operate but do not own, the owner of the property, generally a municipality, usually holds the permit and we operate the landfill pursuant to a landfill operating agreement for a contracted term, which may be the life of the landfill. Where the contracted term is not the life of the landfill, the property owner is generally responsible for final capping, closure and post-closure obligations. We are responsible for all final capping, closure and post-closure obligations at our operated landfills for which we have life-of-site agreements.

Based on remaining permitted capacity as of December 31, 2021, and projected annual disposal volumes, the average remaining landfill life for our owned and operated landfills and landfills operated, but not owned, under life-of-site agreements, is estimated to be approximately 29 years. Many of our existing landfills have the potential for expanded disposal capacity beyond the amount currently permitted. We regularly consider whether it is advisable, in light of changing market conditions and/or regulatory requirements, to seek to expand or change the permitted waste streams or to seek other permit modifications. We also monitor the available permitted in-place disposal capacity of our landfills on an ongoing basis and evaluate whether to seek capacity expansion using a variety of factors.

We are currently seeking to expand permitted capacity at 13 of our landfills, for which we consider expansions to be probable. Although we cannot be certain that all future expansions will be permitted as designed, the average remaining landfill life for our owned and operated landfills and landfills operated, but not owned, under life-of-site agreements is estimated to be approximately 33 years when considering remaining permitted capacity, probable expansion capacity and projected annual disposal volume.

The following table reflects estimated landfill capacity and airspace changes, as measured in tons, for owned and operated landfills and landfills operated, but not owned, under life-of-site agreements (in thousands):

The expiration dates for the five operated landfills range from 2022 to 2042.  We are seeking or intend to seek renewal of all five contracts prior to, or upon, their expiration.

Transfer Station Services

We own or operate MSW transfer stations and E&P waste transfer stations with marine access. Transfer stations receive, compact and/or load waste to be transported to landfills or treatment facilities via truck, rail or barge. They extend our direct-haul reach and link collection operations or waste generators with distant disposal or treatment facilities by concentrating the waste stream from a wider area and thus providing better utilization rates and operating efficiencies.

Recycling Services

We offer residential, commercial, industrial and municipal customers recycling services for a variety of recyclable materials, including compost, cardboard, mixed paper, plastic containers, glass bottles and ferrous and aluminum metals. We own and operate recycling operations and market collected recyclable materials to third parties for processing before resale. The majority of the recyclables we process for sale are paper products and are shipped to customers in the United States and Canada, as well as other markets, including Asia. Changes in end market demand as well as other factors can cause fluctuations in the prices for such commodities, which can affect revenue, operating income and cash flows. We believe that recycling will continue to be an important component of local and state solid waste management plans due to the public’s increasing environmental awareness and expanding regulations that mandate or encourage recycling. We also believe that the costs of processing recyclables, including the costs of contamination, which have historically been subsidized by the sale of recycled commodities, need to be fully recognized. To that end, we have increased the fees that we charge for the collection of recyclables and for processing at our recycling facilities to more fully reflect the processing costs associated with the separation of recyclables into marketable commodities. In some instances, we will look to pass the risk associated with the volatility of recycled commodity prices onto our customers.

Beneficial Reuse of Landfill Gas

We develop, own and operate projects for the beneficial reuse of landfill gas through our landfill network.  Over time, landfill gas is produced as waste decomposes at landfills, and the methane component is a readily available renewable energy source that can be gathered and converted into a valuable source of clean energy as recognized by the United States Environmental Protection Agency, or the EPA, in the same category as wind, solar, and geothermal resources. As of December 31, 2021 we have gas recovery systems at 53 of our landfills to collect methane, which can then be used to generate electricity for local households, fuel local industrial power plants or power alternative fueled vehicles. For 18 of these beneficial reuse projects, the processed gas is used to fuel electricity generators.  The electricity is then sold to public utilities.  For 9 of these projects, the landfill gas is processed to pipeline quality natural gas and sold to natural gas companies.  In some cases, landfill gas generated at our landfills qualifies as a renewable fuel for which renewable fuel credits may be available.  

E&P Waste Treatment, Recovery and Disposal Services

E&P waste is a broad term referring to the by-products resulting from oil and natural gas exploration and production activity. These generally include: waste created throughout the initial drilling and completion of an oil or natural gas well, such as drilling fluids, drill cuttings, completion fluids and flowback water; production wastes and produced water during a well’s operating life; contaminated soils that require treatment during site reclamation; and substances that require clean-up after a spill, reserve pit clean-up or pipeline rupture. E&P waste customers are oil and natural gas exploration and production companies operating in the areas that we serve. E&P waste revenue is therefore driven by vertical and horizontal drilling, hydraulic fracturing, production and clean-up activity; it is complemented by other services including closed loop collection systems and the sale of recovered products. E&P waste activity varies across market areas which are tied to the natural resource basins in which the drilling activity occurs and reflects the regulatory environment, pricing and disposal alternatives available in any given market.

We provide E&P waste treatment, recovery and/or disposal services from a network of E&P waste landfills, MSW landfills that also receive E&P waste, E&P liquid waste injection wells and E&P waste treatment and oil recovery facilities. Treatment processes vary by site and regulatory jurisdiction. At certain treatment facilities, loads of flowback and produced water and other drilling and production wastes delivered by our customers are sampled, assessed and tested by third parties according to state regulations. Solids contained in a waste load are deposited into a land treatment cell where liquids are removed from the solids and are sent through an oil recovery system before being injected into saltwater disposal injection wells or placed in evaporation cells that utilize specialized equipment to accelerate evaporation of liquids. In certain locations, fresh water is then added to the remaining solids in the cell to “wash” the solids several times to remove contaminants, including oil and grease, chlorides and other contaminants, to ensure the solids meet specific regulatory criteria that, in certain areas, are administered by third-party labs and submitted to the regulatory authorities.

COMPETITION

The North America MSW services industry is highly competitive and requires substantial labor and capital resources. Our competition includes: three publicly-held solid waste companies—Waste Management, Inc., Republic Services, Inc. and GFL Environmental, Inc.; several regional, publicly held and privately owned companies; and several thousand small, local, privately owned companies, including independent waste brokers, some of which we believe have accumulated substantial goodwill in their markets. We compete for collection, transfer and disposal volume based primarily on the price and, to a lesser extent, quality of our services. We also compete with operators of alternative disposal facilities, including incinerators, and with counties, municipalities and solid waste districts that maintain their own waste collection and disposal operations. Public sector operators may have financial and other advantages over us because of their access to user fees and similar charges, tax revenues, tax-exempt financing and the ability to flow-control waste streams to publicly owned disposal facilities.

From time to time, competitors may reduce the price of their services in an effort to expand their market shares or service areas or to win competitively bid municipal contracts. These practices may cause us to reduce the price of our services or, if we elect not to do so, to lose business. We provide a significant amount of our residential, commercial and industrial collection services under exclusive franchise and municipal contracts and G Certificates. Exclusive franchises and municipal contracts may be subject to periodic competitive bidding. Competition in the solid waste industry is also affected by the increasing national emphasis in the U.S. and Canada on recycling and other waste reduction programs, which may reduce the volume of waste we collect or deposit in our landfills.

The U.S. and Canadian MSW services industries have undergone significant consolidation, and we encounter competition in our efforts to acquire collection operations, transfer stations and landfills. We generally compete for acquisition candidates with publicly owned regional and national waste management companies. Accordingly, it may become uneconomical for us to make further acquisitions or we may be unable to locate or acquire suitable acquisition candidates at price levels and on terms and conditions that we consider appropriate, particularly in markets we do not already serve.

Competition for E&P waste comes primarily from smaller regional companies that utilize a variety of disposal methods and generally serve specific geographic markets. We also compete in certain markets with publicly held and privately owned companies such as Waste Management, Inc., Republic Services, Inc., Clean Harbors, Inc., US Ecology, Inc., Secure Energy Services Inc., Nuverra Environmental Solutions, Trinity Environmental Services, LLC, Ecoserv, Oilfield Water Logistics (OWL) and others. In addition, customers in many markets have the option of using internal disposal methods or outsourcing to another third-party disposal company.

REGULATION

Introduction

Our operations in the United States and Canada, including landfills, transfer stations, solid waste transportation, intermodal operations, vehicle maintenance shops, fueling facilities and oilfield waste treatment, recovery and disposal operations, are all subject to extensive and evolving federal, state, provincial and, in some instances, local environmental, health and safety laws and regulations, the enforcement of which has become increasingly stringent. These laws and regulations may, among other things, require securing permits or other authorizations (collectively, “permits”) for regulated activities; govern the amount and type of substances that may be discharged or emitted into the environment in connection with our operations; impose cleanup or corrective action responsibility for releases of regulated substances into the environment; restrict the way we handle, manage or dispose of wastes; limit or prohibit our activities in sensitive areas such as wetlands, wilderness areas or areas inhabited by endangered or threatened species; require investigatory and remedial actions to mitigate pollution conditions caused by our operations or attributable to former ownership or operations; and impose specific standards addressing worker protection and health. Compliance is often costly or difficult to achieve, and the violation of these laws and regulations may result in the denial or revocation of permits, issuance of corrective action orders, assessment of administrative and civil penalties and even potentially criminal prosecution.

In many instances in the United States, liability is often “strict,” meaning it is imposed without a requirement of intent or fault on the part of the regulated entity. The environmental regulations that affect us in the United States are generally administered by the Environmental Protection Agency, or the EPA, state environmental agencies, and other federal, state and local authorities having jurisdiction over our U.S. operations.

The environmental legislation affecting us in Canada is administered by federal and provincial regulatory agencies, which have jurisdiction over certain aspects of our Canadian operations. The relevant Canadian federal environmental legislation that affects our operations is administered by federal departments such as Environment and Climate Change Canada. Provincial and local agencies and departments administer their own environmental legislation, such as the Ontario Ministry of the Environment, Conservation and Parks. In most instances in Canada, liability for violations of environmental and health and safety laws is imposed without a requirement of intent on the part of the regulated entity, but is subject to a defense of due diligence.

Compliance with existing environmental regulatory requirements and permits requires significant capital and operating expenditures. It is possible that substantial costs for compliance or penalties for non-compliance may be incurred in the future. We believe that in recent years, environmental regulation of the industry has increased as have the number of enforcement actions brought by regulatory agencies. It is also possible that other developments, such as the adoption of additional or more stringent environmental laws, regulations and enforcement policies, could result in additional costs or liabilities that we cannot currently foresee or quantify. Moreover, changes in environmental laws or regulations could reduce the demand for our services and adversely impact our business. We also expend significant resources (both administrative and financial) directed toward development, expansion, acquisition, and permitting of landfills, transfer stations, and other facilities we operate. Regarding any permit issued by a regulatory agency necessary for our operations, there are no assurances that we will be able to obtain or maintain all necessary permits or that any such permit held may ultimately be renewed on the same or similar terms. Further, permits obtained impose various requirements and may restrict the size and location of disposal operations, impose limits on the types and amount of waste a facility may receive or manage, as well as a waste disposal facility’s overall capacity. Additional operational conditions or restrictions may be included in the renewal or amendment of a previously issued permit. As regulations change, our permit requirements could become more stringent and compliance may require material expenditures at our facilities, impose significant operational restraints, or require new or additional financial assurance related to our operations. Regarding any permit that has been issued, it remains subject to renewal, modification, suspension or revocation by the agency with jurisdiction.

Various laws impose cleanup or remediation liability on responsible parties, which are discussed in more detail below. Substances subject to cleanup liability have been or may have been disposed of or released on or under certain of our facility sites. At some of our facilities, we have conducted and continue to conduct monitoring or remediation of known soil and groundwater contamination and, as required, we will continue to perform such work. It is possible that monitoring or remediation could be required in the future at other facilities we own or operate, or previously owned or operated. These monitoring and remediation efforts are usually overseen by environmental regulatory agencies. Further, it is not uncommon for neighboring landowners or other third parties to file claims for personal injury or property damage allegedly caused by the release of regulated substances into the environment. In addition, from time to time, our intermodal services business undertakes the transport of hazardous materials. This transportation function is also regulated by various federal, state, provincial and potentially local agencies.

A number of major statutes and regulations apply to our operations, which are generally enforced by regulatory agencies. Typically, in the United States, federal statutes establish the general regulatory requirements governing our operations, but in many instances these programs are delegated to the states, which have independent and sometimes more strict regulation. In Canada, it is typically provincial statutes that establish the primary regulatory requirements governing our waste operations. Federal statutes in Canada govern certain aspects of waste management, including international and interprovincial transport of certain kinds of waste. Certain of these statutes in the United States and Canada contain provisions that authorize, under certain circumstances, lawsuits by private citizens to enforce certain statutory provisions. In addition to penalties, some of these statutes authorize an award of attorneys’ fees to parties that successfully bring such an action. Enforcement actions for a violation of these statutes and related rules, or for a violation of or failure to have a permit, which is required by certain of these statutes, may include administrative, civil and criminal/regulatory penalties, as well as injunctive relief in some instances. In our ordinary course of business, we incur significant costs complying with these statutes, regulations and applicable standards they impose.

12

Table of Contents

A brief description of certain of the primary statutes affecting our operations is discussed below.

Laws and Regulations

A.   Waste and Hazardous Substances

1.   The Resource Conservation and Recovery Act of 1976, or RCRA

In the United States, RCRA regulates the generation, treatment, storage, handling, transportation and disposal of hazardous and non-hazardous waste and requires states to develop programs to ensure the safe disposal of solid waste. Regulations promulgated under RCRA impose broad requirements on the waste management industry. In October 1991, the EPA adopted what are known as the Subtitle D Regulations, which govern solid non-hazardous waste landfills. The Subtitle D Regulations establish, among other things, location restrictions, minimum facility design and performance standards, operating criteria, closure and post-closure requirements, financial assurance requirements, groundwater monitoring requirements, groundwater remediation standards and corrective action requirements. These and other applicable requirements, including permitting, are typically implemented by the states, and in some instances, states have enacted more stringent requirements.

Waste related to oil and gas exploration and production, or E&P, is typically regulated differently than those wastes designated as “hazardous waste.” Regarding the management and disposal of E&P waste, although E&P wastes may contain hazardous constituents, most E&P waste is exempt from stringent RCRA regulation as a hazardous waste. We are required to obtain permits for the land treatment and disposal of E&P waste as part of our operations. The construction, operation and closure of E&P waste land treatment and disposal operations are generally regulated at the state level. These regulations vary widely from state to state. None of our oilfield waste recycling, treatment and disposal facilities are currently permitted to accept hazardous wastes. Some wastes handled by us that currently are exempt from regulation as hazardous wastes may in the future be designated as “hazardous wastes” under RCRA or other applicable statutes if changes in laws or regulations were to occur. If the RCRA E&P waste exemption is repealed or modified, we could become subject to more rigorous and costly operating and disposal requirements.

A breach of laws or regulations governing facilities we operate may result in suspension or revocation of necessary permits, civil liability, and imposition of fines and penalties. Moreover, if we experience a delay in obtaining, are unable to obtain, or suffer the revocation of required permits, we may be unable to serve our customers, our operations may be interrupted and our growth and revenue may be limited.

RCRA also regulates underground storage of petroleum and other materials it defines as “regulated substances.” RCRA requires tank registration, compliance with technical standards for tanks, release detection and reporting and corrective action, among other things. Certain of our facilities and operations are subject to these requirements, which are typically implemented at the state level and may be more stringent in certain states.

2.   The Comprehensive Environmental Response, Compensation and Liability Act of 1980, or CERCLA

CERCLA, which is also known as the “Superfund” law, established a program in the United States allowing federal authorities to provide for the investigation and cleanup of facilities where, or from which, a release of any hazardous substance into the environment has occurred or is threatened. CERCLA defines “hazardous substances” broadly. One of the primary ways that CERCLA addresses a release or threatened release of hazardous substances is by imposing strict, joint and several liability for cleanup on its broad categories of responsible parties. This means that responsible parties can bear liability without fault and that each responsible party potentially could bear liability for the entirety of cleanup costs, notwithstanding its individual contribution. Generally, responsible parties are current owners and/or operators of the contaminated site; former owners and operators of the site at the time when the hazardous substances were disposed; any person who arranged for treatment or disposal of the hazardous substances; and transporters who selected the disposal site. In addition to CERCLA’s liability framework, the EPA may issue orders directing responsible parties to respond to releases of hazardous substances. Further, the EPA and private parties, who have response liability to the EPA or who have incurred response costs, can bring suit against other responsible parties to seek to recover certain costs incurred in their response efforts. CERCLA also imposes liability for the cost of evaluating and remedying damage to natural resources. Various

13

Table of Contents

states have enacted laws analogous to and independent of CERCLA that also impose liability, which is typically strict and joint and several, for investigation, cleanup and other damages associated with the release of hazardous or other regulated substances. We may handle hazardous substances within the meaning of CERCLA, or hazardous and other substances regulated under similar state statutes, in the course of our ordinary operations. As a result, we may be jointly and severally liable under CERCLA or similar states statutes for all or part of the costs required to cleanup sites if and where these hazardous substances have been released into the environment. CERCLA and these analogous state laws and regulations may also expose us to liability for acts or conditions that were in compliance with applicable laws at a prior time. Under certain circumstances, our sales of residual crude oil collected as part of the saltwater injection process could result in liability to us if the residual crude contains hazardous substances or is covered by one of the state statutes and the entity to which the oil was transferred fails to manage and, as necessary, dispose of it or components thereof in accordance with applicable laws. Additionally, the EPA is considering the possible inclusion of certain additional contaminants to CERCLA’s list of hazardous substances. Among these substances are per- and polyfluoroalkyl substances, PFAS, and bisphenol A, or BPA. The inclusion of these substances in CERCLA’s definition of hazardous substances may alter or increase cleanup liabilities associated with ongoing cleanup activities, or potentially give rise to additional liability, including for acts or conditions that were in compliance with applicable laws when they occurred.

3.   Canadian Waste Legislation

The primary waste laws regulating our business in Canada are imposed by the provinces. These include provincial laws that regulate waste management, including requirements to obtain permits and approvals, and regulations with respect to the operation of transfer stations and landfilling sites. Each provincial jurisdiction in Canada has its own regulatory regime; however, the key requirements under these regimes are similar across Canada. For example, the Environmental Protection Act, or the EP Act, in Ontario and its underlying regulations regulate the generation, treatment, storage, handling, transportation and disposal of wastes in Ontario, among other things. The EP Act requires an approval or, in some cases, a registration, for the establishment, operation or alteration of a waste management system (which includes all facilities or equipment used in connection with waste) or a waste disposal site. The specific terms and conditions of an approval may impose emission limits, monitoring and reporting requirements, siting and operating criteria, financial assurance or insurance and decommissioning requirements. Certain landfilling sites are subject to more stringent regulatory requirements that can include detailed prescribed design standards, leachate collection systems, landfill gas management or collection systems and/or site closure plans including post-closure care requirements. The federal Canadian Environmental Protection Act, 1999 imposes requirements with respect to the interprovincial and international movement of hazardous wastes and hazardous recyclable material, which can affect the movement of wastes and recyclables to our Canadian facilities. The expansion or establishment of certain waste management projects, including waste treatment and landfilling sites, may also be subject to provincial or federal environmental assessment requirements.

A breach of laws or regulations governing our operations may result in suspension or revocation of necessary approvals and imposition of fines and penalties. Moreover, if we experience a delay in obtaining, are unable to obtain, or suffer the revocation of required approvals, we may be unable to serve our customers, our operations may be interrupted, and our growth and revenue may be limited.

4.   Canadian Contaminated Sites Legislation

There are provincial and federal laws in Canada that regulate spills and releases of substances into the environment and require the remediation of contaminated sites. Clean up of contaminated sites in connection with our business is primarily regulated by provincial environmental laws. Each province has its own regulatory regime; however, the key requirements under these regimes are similar across Canada. For example, the EP Act in Ontario authorizes the agency to issue orders to responsible persons to undertake remedial or other corrective actions to investigate, monitor, and remediate the discharge or presence of contaminants in the environment. These orders can generally be issued on a joint and several liability basis to categories of responsible persons, including persons who caused or permitted the discharge of a contaminant, persons who owned the discharged substance, as well as current and past owners of lands or the source of the contamination and persons who have or have had management or control over lands or the source of the contamination. Responsible parties can bear liability under an order without fault.  The costs to comply with an order can be very substantial. Some provincial jurisdictions provide a statutory right to compensation from the owner or person in control of a substance that is discharged into the environment to any person who suffers loss as a result. The federal government has

14

Table of Contents

also enacted laws that regulate the release of certain substances into the environment. We handle many contaminants and pollutants in the course of our ordinary operations and, as a result, may be liable under provincial and federal statutes for all or part of required cleanup costs if substances have been released into the environment. Under such laws, we could be required to remove previously disposed substances and wastes (including substances disposed of or released by prior owners or operators) or remediate contaminated property (including soil and groundwater contamination, whether from prior owners or operators or other historic activities or spills).

B.   Wastewater/Stormwater Discharge

1.   The Federal Water Pollution Control Act of 1972, or the Clean Water Act

The Clean Water Act regulates the discharge of pollutants from a variety of sources, including, without limitation, solid waste disposal facilities, transfer stations and oilfield waste facilities into Waters of the United States, or WOTUS, including surface and potentially ground waters. Under the Clean Water Act, sites or facilities that discharge pollutants to waters of the United States must have a permit authorizing that discharge. If certain materials such as run-off, collected leachate, or other contaminants from our owned or operated facilities, including landfills, transfer stations, or other facilities, are discharged into streams, rivers or other regulated waters, the Clean Water Act requires a discharge permit. These permits typically contain requirements to conduct monitoring and, under certain circumstances, to treat and reduce the quantity of pollutants in such discharge. Further, if a landfill or other facility discharges wastewater through a treatment works, it may be required to comply with additional permitting or treatment, and other specific requirements. Also, virtually all landfills are required to comply with the EPA’s storm water regulations, which are designed to prevent the introduction of contaminated storm water run-off into United States’ waters.

At this time, the ultimate regulatory test for defining WOTUS is unsettled, and the determination therefore will be based upon the outcome of regulatory promulgations and associated litigation, that are currently pending. The manner in which WOTUS is defined could affect our operations by potentially increasing or modifying regulatory requirements governing our discharges. In 2015, the Clean Water Rule was promulgated, which would expand federal control over many U.S. water resources by broadening the definition of WOTUS, thereby potentially classifying a larger range of water resource types as jurisdictional under the Clean Water Act. Since promulgation of the 2015 Clean Water Rule, the EPA and the Army Corps of Engineers, or the Corps, have sought to rescind it and to promulgate a revised definition of WOTUS that would establish federal jurisdiction more narrowly, thereby reducing the scope of Clean Water Act applicability. To that end, on December 11, 2018, the EPA and the Corps proposed a rule to redefine WOTUS. Eventually, in October 2019, the 2015 Clean Water Rule was repealed, effectively reverting to the pre-2015 regulatory definition as of December 23, 2019.  On April 21, 2020, the EPA published a new Navigable Waters Protection Rule, or NWPR, narrowing the scope of federal jurisdiction over waterways and wetlands. This rule went into effect on June 22, 2020. In 2021, the NWPR was vacated and remanded by two separate federal district courts.  In response to these decisions, the EPA halted implementation of the NWPR, stating that it would now be “interpreting [WOTUS] consistent with the pre-2015 regulatory regime until further notice.”  On December 7, 2021, the EPA and the Corps published a proposed rule restoring definitions used before the 2015 Rule, relying on case-by-case wetland and waterway determinations. As of the time of the proposed rule’s publication, there were approximately 14 pending cases challenging the 2015 Clean Water Rule, the 2019 rule repealing the Clean Water Rule, and the 2020 NWPR. If the December 2021 proposed rule is finalized, further litigation may be brought. As a result, the scope of the WOTUS definition will likely remain fluid until both rulemaking and pending litigation is finalized. If the proposed rule is finalized as published, and the EPA and Corps expand the scope of the jurisdiction under the Clean Water Act with respect to WOTUS, we could face increased costs and delays in obtaining permits under the Clean Water Act.  Further, this regulatory uncertainty may increase costs to our customers. As a result, an expansion of the scope of the WOTUS definition could adversely affect our business.

Additionally, the Clean Water Act’s spill prevention, control and countermeasure requirements require development of site-specific plans, and appropriate containment berms and similar structures to help contain and prevent the contamination of regulated waters in the event of a hydrocarbon storage tank release. The Clean Water Act also contains provisions that can prohibit development or require permitting before construction or expansion of a landfill may occur in areas designated as wetlands. Various states in which we operate or may operate in the future have been delegated authority to implement the Clean Water Act and its permitting requirements, and some of these states have adopted regulations that

15

Table of Contents

are more stringent than federal Clean Water Act requirements, including regulating discharges to state waters in addition to WOTUS.

2.   Safe Drinking Water Act, or SDWA

Our United States E&P underground injection operations are subject to, among other laws, the SDWA, as well as analogous state laws and regulations. Under the SDWA, the EPA established the underground injection control, or UIC, program, which includes requirements for permitting, testing, monitoring, record keeping and reporting of injection well activities, as well as a prohibition against the migration of fluid containing any contaminant into underground sources of drinking water. Certain state regulations require us to obtain permits from the applicable regulatory agencies to operate our underground injection wells. Leakage from the subsurface portions of injection wells could cause degradation of fresh groundwater resources, potentially resulting in suspension of our UIC permit, fines and penalties, the incurrence of expenditures for remediation of the affected resource and potential liability to third parties for property damages.

The EPA has been reviewing whether management and disposal of E&P wastes should be subject to additional regulation. In July 2018, the EPA partnered with New Mexico to assess alternatives to immediate disposal of E&P wastewater by reusing it and/or treating it for reintroduction into the hydrologic cycle, as well as potential regulations related thereto. Moreover, in May 2019, EPA issued its draft Study of Oil and Gas Extraction Wastewater Management Under the Clean Water Act regarding EPA’s examination of whether to alter its regulation of the treatment and discharge of E&P wastewater. The final report was released in May 2020. The EPA has yet to determine its next steps for managing E&P wastewater under the Clean Water Act.  If regulations requiring reuse or treatment are developed and implemented on a broad scale, it may increase our (or our customers’) compliance costs or reduce the volume of E&P wastes that may be disposed of via underground injection, which could have an adverse effect on our business.

3.   Canadian Water Protection Legislation

There is legislation in Canada at both the federal and provincial levels that protects water quality and regulates the discharge of substances into the aquatic environment. Federal water pollution control authority is derived primarily from the Fisheries Act, which contains provisions for the protection of water quality and fish habitat. This includes a general prohibition on the deposit of any deleterious substances into water that is frequented by fish, unless otherwise authorized. There is legislation in each provincial jurisdiction that also protects water sources and regulates water pollution, and generally requires an approval or permit for a discharge of any effluent, including in some cases stormwater, into a water body. For example, in Ontario, the Ontario Water Resources Act, or OWRA, prohibits the discharge of material of any kind into any water that may impair the quality of the water. The OWRA requires that an approval be obtained for the use and operation of certain sewage and stormwater works. Such approvals typically contain monitoring requirements and impose restrictions on effluent characteristics. Other provinces in Canada have similar regimes for the protection of water. If run-off or other contaminants from our landfills, transfer stations or other waste facilities are discharged or migrate into waters and cause impairment, we could face significant liability under provincial and federal laws.

C.   Air Emissions

1.   The Clean Air Act, or CAA

In the United States, the CAA generally regulates the emissions of air pollutants from a variety of sources, including certain landfills and oilfield waste facilities, based on factors such as the date of the construction and tons per year of emissions of regulated pollutants. Typically, federal requirements are delegated to the states and implemented at the state level. The CAA and analogous state laws require permits for and impose other restrictions on facilities and equipment that have the potential to emit pollutants into the atmosphere. Under the CAA, generally a facility deemed to be a major source must be authorized by a permit, known as a federal operating permit. Additional or more stringent regulations of our facilities may occur in the future, which could increase operating costs or impose additional compliance burdens.

In those situations where major source permitting is not required, typically state laws and rules will require permitting as a type of minor source. Larger landfills and landfills located in areas where the ambient air does not meet certain air quality standards called for by the CAA may be subject to even more extensive air pollution controls and emissions

16

Table of Contents

limitations. In addition to the potential air emissions permitting of landfill facilities, such permitting may be required for the construction of gas collection and flaring systems, composting and other operations giving rise to emissions. In some instances, major source federal operating permits, may be required depending on the nature and volume of air emissions.

In addition to permitting, the CAA imposes other regulatory obligations, including, in some instances, performance standards on operations and equipment. For example, in certain instances, major sources are subject to emissions limitations known as maximum achievable control technology, or MACT. The EPA has promulgated regulations requiring MACT on large MSW landfills. The MACT standards imposed on landfill emissions often require installation of landfill gas collection systems. The EPA has also issued what are known as new source performance standards, or NSPS, which detail requirements regarding control of landfill gases from new, modified, or reconstructed, among other things, MSW landfills. Regarding facilities that are not subject to the NSPS, the EPA has promulgated emissions guidelines, specifying standards of performance for existing MSW landfills. The emissions guidelines are implemented and enforced by states through State Implementation Plans, or SIPs, which contain the state-specific regulations and guidance directly applying the emissions guidelines to affected sources in the state through permitting, monitoring, and other means. If one or more states do not submit approvable SIPs by the emissions guideline’s prescribed deadline, the EPA is required to promulgate what is known as a Federal Implementation Plan, or FIP, for the emissions guideline, which then governs the operation of covered sources in states and territories without SIPs in place.

Applicability of NSPS, emissions guidelines, and implementation plans generally depends on whether the MSW landfill facility is a “new source” or an “existing source.” New sources, which are subject to NSPS requirements, generally are those MSW landfill facilities that were constructed, modified, or reconstructed after July 17, 2014. Existing sources, which are subject to the emissions guidelines and their associated state and federal implementation plans, are generally those landfills that commenced construction, modification, or reconstruction on or before July 17, 2014.

New sources are subject to NSPS under Title 40, Part 60, Subpart XXX of the Code of Federal Regulations (Subpart XXX), which were issued on August 29, 2016. Subpart XXX specifies standards for landfill gas control. The Subpart XXX NSPS reduces the threshold for non-methane organic compounds at which new, reconstructed, or modified MSW landfills must install emission controls. Subpart XXX also requires monitoring surface emissions of methane, monitoring of temperature and pressure at the wellhead of landfill gas collection systems and imposes other requirements.

Existing landfills, which are not subject to NSPS Subpart XXX, are indirectly governed by the emissions guidelines and the SIPs or FIPs implementing these requirements. The EPA promulgated what are known as the Subpart Cf emissions guidelines on August 29, 2016. These emissions guidelines triggered a requirement for states to submit SIPs implementing the emissions guidelines limits. In February 2020, the EPA found that 42 states and territories had failed to submit approvable SIPs by the deadline, which had been extended to 2019. The EPA published its proposed FIP in August 2019, and finalized it in May 2021 with an effective date of June 21, 2021. The FIP imposed compliance requirements consistent with Subpart Cf for existing sources in those states without an EPA-approved SIP. The FIP also replaced compliance obligations under certain legacy regulations.  Together, the Subpart XXX and Subpart Cf regulations lower the non-methane organic compounds applicability threshold at which both new and existing MSW landfills must install a gas collection and control system, and impose other regulatory requirements. As a result of this and other regulatory actions affecting air emissions from our facilities, it is possible that we could face greater operational burdens and costs, as well as other requirements could have a material effect on landfill operations, and adversely affect our business.

Additionally, in March 2020, the EPA finalized amendments to the most recent MSW Landfill NSPS and emission guidelines that would allow regulated entities to demonstrate compliance with landfill gas control, operating, monitoring, recordkeeping, and reporting requirements by following the corresponding requirements in the MSW Landfills National Emissions Standards for Hazardous Air Pollutant, or NESHAP, regulations at Subpart AAAA. These amendments were intended to improve compliance and implementation of the regulations. Compliance with these regulatory requirements could result in significant additional costs, which we will incur in our ordinary course of business. In addition, state air regulatory agencies may request delegation of authority to implement the FIP and state law requirements may impose additional restrictions beyond federal requirements, which could also result in compliance costs. For example, some state air programs uniquely regulate odor and the emission of certain specific toxic air pollutants.

17

Table of Contents

The EPA recently modified, or is in the process of modifying, other standards promulgated under the CAA in a manner that could increase our compliance costs. For example, the EPA has discussed modifying national ambient air quality standards, or NAAQS, applicable to carbon monoxide and oxides of sulfur and nitrogen, as well as other standards, to make them more stringent. The NAAQS standards for particulate matter, published December 18, 2020, retained the NAAQS levels from 2012, and the ozone NAAQS, published December 31, 2020, retained 2015 NAAQS levels. These standards must be reviewed every five years, and the current administration may propose more restrictive standards in the future. It is possible these additional regulations could result in, among other things, additional capital or operating expenditures. Further, our customers’ operations may be subject to existing and future CAA permitting and regulatory requirements that could have a material effect on their operations, which could have an adverse effect on our business, increase the operating costs, and otherwise financial condition and operating results.

Further, the EPA published a proposed rule in November 2021 aimed at reducing GHG emissions from the oil and natural gas sector by limiting methane and VOC emissions from new sources constructed or modified after November 2021, proposing an Emission Guideline for certain existing sources, and amending NSPS OOOOa to rescind changes made during the prior administration. While these changes should not directly affect our waste disposal operations, their applicability to our customers in the E&P industry may result in decreased development and, therefore, decreased waste production. If these rules are enacted as written, we may experience a decreased demand for E&P waste disposal services.

2.   Canadian Air Quality Legislation

In Canada, the primary laws regulating air emissions from our operations come from provincial laws. Provincial laws may require approvals for air emissions and may impose other restrictions on facilities and equipment that have the potential to emit pollutants into the atmosphere. Provincial laws may require the construction of landfill gas management systems, including gas collection and flaring systems, which are subject to approvals or other regulatory requirements. Failure to obtain an approval or comply with approval requirements could result in the imposition of substantial administrative or regulatory penalties.

D.   Occupational Health and Safety

1.   The Occupational Safety and Health Act of 1970, or the OSH Act

In the United States, the OSH Act is administered by the Occupational Safety and Health Administration, or OSHA, and many state agencies whose programs have been approved by OSHA. The OSH Act establishes employer responsibilities for worker health and safety, including the obligation to maintain a workplace free of recognized hazards likely to cause death or serious injury, comply with adopted worker protection standards, maintain certain records, provide workers with required disclosures, and implement certain health and safety training programs. Various OSHA standards may apply to our operations, including standards concerning notices of hazards, safety in excavation and demolition work, the handling of asbestos and asbestos-containing materials and worker training and emergency response programs. Moreover, the Department of Transportation, OSHA, and other agencies regulate and have jurisdiction concerning the transport, movement, and related safety of hazardous and other regulated materials. In some instances, state and local agencies also regulate the safe transport of such materials to the extent not preempted by federal law.

2.   Canadian Occupational Health and Safety Laws

In Canada, each province establishes and administers a provincial occupational health and safety regime. Similar to the United States, these regimes generally identify the rights and responsibilities of employers, supervisors and workers. Employers are required to implement all prescribed safety requirements and to exercise reasonable care to protect employees from workplace hazards, among other things. Various occupational health and safety standards may apply to our Canadian operations, including requirements relating to communication of and exposure to hazards, safety in excavation and demolition work, the handling of asbestos and asbestos-containing materials and worker training and emergency response programs. In addition to the provincial departments of transportation, Transport Canada has jurisdiction to regulate the transportation of dangerous goods, which can include wastes.

E.   Additional Regulatory Considerations

We also review regulatory developments that may affect our business, including, among others, those described below.

1.   State, Provincial and Local Regulation

In addition to the federal statutes regulating our operations, each state or province where we operate or may operate in the future has laws and regulations governing the management, generation, storage, treatment, handling, transportation, and disposal of solid waste, E&P waste, occupational safety and health, water and air pollution and, in most cases, the siting, design, operation, maintenance, corrective action, closure and post-closure maintenance of landfills and transfer stations. Further, many municipalities have enacted or could enact ordinances, local laws and regulations affecting our operations, including zoning and health measures that limit solid waste management activities to specified sites or activities. Other jurisdictions have enacted “fitness” rules focusing on companywide and overall corporate compliance history in making permitting decisions. In addition, certain jurisdictions have enacted flow control provisions that direct or restrict the delivery of solid wastes to specific facilities, laws that grant the right to establish franchises for collection services and bidding for such franchises and bans or other restrictions on the movement of solid wastes into a municipality. Specific state and local permits for our operations may be required and may be subject to periodic renewal, modification or revocation by the issuing agencies. There has also been an increasing trend at the state, provincial and local levels to mandate and encourage waste reduction at the source and recycling, and to prohibit or restrict landfill disposal of certain types of solid wastes, such as food waste, yard waste, leaves, tires, electronic equipment waste, painted wood and other construction and demolition debris. The enactment of laws or regulations reducing the volume and types of wastes available for transport to and disposal in landfills could prevent us from operating our facilities at their full capacity.

2.    Hydraulic Fracturing Regulation

We do not conduct hydraulic fracturing operations, but we do provide treatment, recovery, and disposal services in the United States for the fluids used and wastes generated by our customers in such operations Recently, there has been increased public concern regarding the alleged potential for hydraulic fracturing to adversely affect the environment, including drinking water supplies. Proposals have been made to enact separate federal, state or local legislation that would increase the regulatory burden imposed on hydraulic fracturing. Laws and regulations have been proposed and/or adopted at the federal, state and local levels that would regulate, restrict or prohibit hydraulic fracturing operations or require the reporting and public disclosure of chemicals used in the hydraulic fracturing process. Certain states and localities have placed moratoria or bans on hydraulic fracturing or the disposal of waste therefrom, or have considered the same.

In June 2016, the EPA promulgated a rule prohibiting discharges of wastewater pollutants from onshore unconventional oil and gas extraction facilities to publicly-owned treatment works, or POTWs. Further, the EPA’s promulgation and subsequent revision of methane and VOC rules between 2016 and 2020 caused regulatory uncertainty for oil and gas exploration and production facilities, including hydraulic fracturing operations.  In December 2021, the EPA again proposed rules to regulate methane and VOCs from the oil and gas industry sources. The proposed rule would enact a new NSPS, under Subpart OOOOb, which would include standards for emission sources not regulated previously under the 2016 NSPS OOOOa. Additionally, the proposed rules include the first oil and gas emissions guidelines for existing sources, known as Subpart OOOOc. If finalized, the emissions guidelines will require states to submit and implement SIPs to enforce the guidelines on existing oil and gas emissions sources.  These emissions guidelines will include fugitive leak detection surveys for smaller well site sources and regular leak detection surveys using optical gas imaging for larger sources well site sources, compressor stations, and pneumatic controllers. If leaks are detected at covered sources, equipment repair or replacement would be required within a certain time period.

If these rules are enacted as proposed, these rules may require oil and gas operators to expend material sums on compliance, including on equipment repair or replacement. The costs associated with OOOOc compliance may reduce our customers’ E&P activities and could have an adverse impact on our business. Additionally, several states have adopted or proposed laws and regulations analogous to or even more stringent than the federal rules that would remain in effect regardless of the outcome of any federal stay or litigation. Further, several states in which we conduct business require oil

and natural gas operators to disclose information concerning their operations, which could result in increased public scrutiny.

The EPA has contemplated additional rule making that could affect the exploration and production industry sector. In May 2014, the EPA issued an Advanced Notice of Proposed Rulemaking, or ANPR, under the Toxic Substances Control Act, or TSCA, seeking comment on whether and how the EPA should regulate the reporting or disclosure of the use of hydraulic fracturing chemical substances and mixtures and their constituents. Several states have implemented such requirements. Additionally, in December 2016, the EPA released a study on the environmental impacts of hydraulic fracturing on drinking water. In that study, the EPA found evidence that hydraulic fracturing activity can impact drinking water resources under some circumstances, but data gaps limited the EPA’s ability to fully assess the matter. The EPA also published in May 2018 a detailed study of centralized waste treatment, or CWT, facilities accepting oil and gas extraction wastewater. The study assessed the regulatory status of CWTs, characteristics of wastewaters discharged from them, available treatment technologies and associated costs. EPA has yet to implement regulations or guidelines based on this study. The impact of rules that the EPA is contemplating, has proposed or has recently promulgated will be uncertain until the rules are finalized and fully implemented.

If new federal, state or local laws, regulations or policies restricting hydraulic fracturing are adopted, such legal requirements could result in delays, eliminate certain drilling and injection activities and make it more difficult or costly for our customers to perform hydraulic fracturing. Any such regulations limiting, prohibiting or imposing operational requirements on hydraulic fracturing could reduce oil and natural gas E&P activities by our customers and, therefore, adversely affect our business. Such laws or regulations could also materially increase our costs of compliance.

3.   Disposal of Drilling Fluids

Certain of our facilities in the United States accept drilling fluids and other E&P wastes for disposal via underground injection.  The disposal of drilling fluids is generally regulated at the state level, and claims, including some regulatory actions, have been brought against some owners or operators of these types of facilities for nuisance, seismic disturbances and other claims in relation to the operation of underground injection facilities. To date, our facilities have not been subject to any such litigation, but could be in the future.

4.   Climate Change Laws and Regulations

Generally, the promulgation of climate change laws or regulations restricting or regulating greenhouse gas, or GHG, emissions from our operations could increase our costs to operate by increasing control technology requirements or changing regulatory obligations. In the United States, the EPA’s current and proposed regulation of GHG emissions may adversely impact our operations. Pursuant to the EPA’s rulemakings and interpretations, certain air permits issued on or after January 2, 2011 must address GHG emissions. As a result, new or modified emissions sources may be required to install Best Available Control Technology to limit GHG emissions, but future regulations may revise these requirements. Additionally, regulations in the Subpart OOO Federal Implementation Plan, the NSPS in Subpart ‎XXX require the reduction of GHG emissions from new ‎or modified landfills‎, as detailed above. In addition, the EPA’s Mandatory Greenhouse Gas Reporting Rule sets monitoring, recordkeeping and reporting requirements applicable to certain landfills and other entities.

In June 2018, the Canadian federal government enacted the Greenhouse Gas Pollution Pricing Act, or GGPPA, which established a national carbon-pricing regime starting in 2019 for provinces and territories in Canada where there is no provincial regime in place or where the provincial regime does not meet the federal benchmark. Often referred to as the federal backstop, the federal carbon-pricing regime consists of a carbon levy that is applied to certain fossil fuels and an output-based pricing system, or OBPS, that is applied to certain industrial facilities with reported emissions of 50,000 tonnes of carbon dioxide equivalent, or CO₂e, or more per year. The minimum national price on carbon established by the GGPPA is equivalent to CAD $40 per tonne of CO₂e in 2021, increasing to CAD $50 per tonne of CO₂e in 2022. In December 2020, the federal government released its plan to accelerate climate action in Canada, entitled "A Healthy Environment and a Healthy Economy".  This plan proposes an annual increase to the carbon price of CAD $15 per year starting in 2023, reaching CAD $170 per tonne of CO₂e by 2030.  The Canadian Net-Zero Emissions Accountability Act, which received royal assent on June 29, 2021, establishes Canada's federal framework for national GHG emissions

20

Table of Contents

reduction targets to attain net-zero emissions by 2050.  While this new Act does not impose direct emission reduction obligations on our operations in Canada, it signifies the Canadian federal government's commitment to achieve GHG emissions reductions.

Certain states and several Canadian provinces have promulgated legislation and regulations to limit GHG emissions through requirements of specific controls, carbon levies, cap and trade programs or other measures. Comprehensive GHG legislation or regulation, including carbon pricing, affects not only our business, but also that of our customers.

Heightened regulation of our customers’ operations could also adversely affect our business. The regulation of GHG emissions from oil and gas E&P operations may increase the costs to our customers of developing and producing hydrocarbons and, as a result, may have an indirect and adverse effect on the amount of E&P waste delivered to our facilities. As discussed above, recently proposed EPA air emission rules applicable to oil and gas production sources in the United States may require additional emissions controls and increased capital costs for our customers, which could reduce their E&P activities, and subsequently negatively impact our business operations. As discussed above, certain states have enacted rules analogous to or even more stringent than the federal rules.

These statutes and regulations increase our costs and our customers’ costs, and future climate change statutes and regulations may have an impact as well. If we are unable to pass such higher costs through to our customers, or if our customers’ costs of developing and producing hydrocarbons increase, our business, financial condition and operating results could be adversely affected. The impact of any potential rules affecting existing sources is uncertain.

5.   Flow Control, Interstate, and International Waste Restrictions

Certain permits and state and local regulations, known as flow control restrictions, may limit a landfill’s or transfer station’s ability to accept waste that originates from specified geographic areas, to import out-of-state waste or wastes originating outside the local jurisdictions or to otherwise accept non-local waste. While certain courts have deemed these laws to be unenforceable, other courts have not. Certain state and local jurisdictions may seek to enforce flow control restrictions contractually. These actions could limit or prohibit the importation of wastes originating outside of local jurisdictions or direct that wastes be handled at specified facilities. These restrictions could limit the volume of wastes we can manage in jurisdictions at issue and also result in higher disposal costs for our collection operations. If we are unable to pass such higher costs through to our customers, our business, financial condition and operating results could be adversely affected. Additionally, certain local jurisdictions have sought or may seek to impose extraterritorial obligations on our operations in an effort to affect flow control and may enforce tax and fee arrangements on behalf of such jurisdictions.

Changes to international waste importation and exportation laws may affect the price of recyclable scrap commodities.  Price fluctuations, in turn, may adversely affect our business. For example, the Chinese government banned the importation of all materials classified by China as solid waste and virtually all recyclables (except for certain metallic recyclables) as of January 1, 2021. Other international restrictions also limit the transportation of waste and recyclable scrap. The Basel Convention on the Control of Transboundary Movements of Hazardous ‎Wastes and their Disposal, or the Convention, is an international multilateral agreement ‎regulating the export and import of waste, including hazardous waste, for recovery and ‎disposal.‎ The Convention also prohibits the movement of waste between parties to the Convention ‎and non-parties‎ unless the waste is moved pursuant to a separate agreement. The Convention was amended, effective January 1, 2021, to restrict the movement of non-hazardous plastic scrap in certain circumstances. Canada is a party to the Convention and has implemented domestic legislation to implement Canada's commitment to the Convention and other similar international commitments. Federal waste regulations in Canada impose restrictions and permitting requirements with respect to transboundary movements of certain hazardous wastes and recyclable materials. The United States is not a party to the Convention; however, Canada and the United States have a separate agreement with respect to the transboundary movements of hazardous wastes.  Increased restriction of transboundary waste shipment could create additional burdens associated with recyclable commodity fluctuation.  These restrictions, in addition to circumstances caused by the COVID-19 pandemic, have caused and may continue to cause supply chain disruptions in the recycling industry.  Further legal restrictions to recyclable scrap shipments may increase the cost of doing business and/or cause disruptions in our operations.

6. Regulation of Per- and Polyfluoroalkyl Substances, or PFAS, and Other Emerging Contaminants

At this time, several substances are being reviewed by governmental authorities for potential heightened regulation, including PFAS. PFAS, a class of man-made chemicals, have been in use since the 1940s and are found in many consumer products including textiles, fire suppressants, cookware, packaging, and plastics. These types of products and materials can be found in wastes that our facilities accept and have accepted for management and disposal. PFAS are environmentally persistent and tend to bioaccumulate in exposed populations. PFAS contamination has been found in the air, soil, and water, including drinking water. This contamination has prompted action by Congress, the EPA, and several states.

The EPA has begun to examine the potential regulation of PFAS materials under the SWDA, ‎RCRA, CERCLA, and TSCA.  The EPA established lifetime health advisories for PFAS ‎materials in May 2016.  Further, in an October 26, 2021 letter to the Governor of New Mexico, the ‎Administrator of the EPA announced that the EPA would initiate a proposed rulemaking to list ‎four PFAS chemicals as “hazardous constituents” under RCRA. The Administrator also stated ‎that EPA would amend its regulations to clarify that “emerging contaminants such as PFAS” can ‎be addressed through the RCRA Corrective Action Program, which gives the EPA authority to ‎require investigation and cleanup for hazardous wastes.  The regulatory development process for listing two PFAS chemicals, perfluorooctanoic acid, or PFOA, and perfluorooctanesulfonic acid, or PFOS, as hazardous substances under CERCLA was initiated in 2019. Listing PFAS as a CERCLA hazardous substance would potentially expand the universe of substances giving rise to cleanup liability. EPA has published Action Plans to potentially address the risk of PFAS contamination. The most recent Action Plan, which was published in February 2020, included preliminary determinations to regulate PFOA and PFOS, as well as an analysis of tools available to regulate PFAS. The EPA also released a memorandum in November 2020 detailing an interim strategy for including PFAS in National Pollutant Discharge Elimination System, or NPDES, waste water discharge permits under the CWA.

The PFAS Act of 2019, as part of the National Defense Authorization Act for Fiscal Year 2020, ‎directed the EPA Administrator to take certain actions with regard to PFAS. Under the 2019 PFAS ‎Act, the EPA was directed to include PFAS substances in the SDWA monitoring program for ‎unregulated contaminants, to add PFAS to the Toxic Release Inventory, or TRI, reporting ‎requirements under the Emergency Planning and Community Right-To-Know Act, or EPCRA, ‎and to promulgate a rule requiring PFAS data submission under TSCA. In July 2021, the PFAS Action ‎Act of 2021 passed the U.S. House of Representatives. The 2021 PFAS Act, if enacted, would direct the EPA to ‎designate certain PFAS chemicals as hazardous substances under CERCLA, hazardous air ‎pollutants under the CAA, and pollutants under the CWA. Additionally, the EPA would be ‎required to issue a national primary drinking water regulation for PFAS. ‎

State governments are also beginning to regulate PFAS. Certain states have taken action to limit exposure to PFAS and require remediation of PFAS-related environmental contamination. Much of the state action has been directed at drinking water limits, but in some instances, bills and policies have included PFAS prohibitions in food packaging, consumer products, and firefighting products.

The EPA is also considering regulation of other contaminants of concern, including bisphenol A (BPA) and phthalates, which are common in PVC products. If the EPA moves forward with regulating these or other contaminants of concern, we may face higher compliance costs for, among other things, treatment of leachate and landfill gas.

PFAS chemicals are the subject of environmental and health reviews by the federal government in Canada. PFAS substances, including PFOS, PFOA, and certain long chain perfluorocarboxylic acids, or LC-PFCA, are listed as toxic substances under the Canadian Environmental Protection Act, 1999 and are subject to restrictions on their use in Canada.  Environmental screening values and standards, and drinking water guidelines, exist in some jurisdictions in Canada in relation to some PFAS substances. The Canadian federal government published a notice in 2021 of its intent to move forward with additional actions to address the broader class of PFAS, including research and monitoring of PFAS, reviewing PFAS as a class of chemicals and reviewing policy developments in other jurisdictions.  Given the increasing concern regarding PFAS in the environment, including PFAS in groundwater and in leachate at waste disposal sites, increased regulatory requirements may be imposed in Canada in the future.

Increased regulation of PFAS and other emerging contaminants could adversely affect our operations. Our already-substantial financial obligations associated with post-closure maintenance at our existing landfills may increase and accruals for these obligations may also need to be increased. Guidance calling for enhanced treatment of landfill leachate and landfill gas could potentially increase burdens for disposal of PFAS-containing materials generated by our facilities or accepted at our facilities, some of which may potentially need to be upgraded to accept PFAS-containing waste. Finally, regulation of PFAS as an air contaminant and/or waste water effluent pollutant could increase the cost to conduct our business, including, without limitation, potentially requiring greater capital expenditures to meet control requirements as well as operation and maintenance costs.

F.   Renewable and Low Carbon Fuel Standards

Pursuant to the Energy Independence and Security Act of 2007, the EPA promulgated the Renewable Fuel Standards, or RFS, which require refiners to either blend “renewable fuels,” such as ethanol and biodiesel, into their transportation fuels or to purchase renewable fuel credits, known as renewable identification numbers, or RINs, in lieu of blending. In some cases, landfill gas generated at our landfills in the United States and Canada qualifies as a renewable fuel for which RINs are available. Such RINs can be sold by the Company.

The price of RINs has been extremely volatile and the value of RINs is dependent upon a variety of factors, including the required volumes promulgated by the EPA. The EPA annually establishes the renewable fuel volumes required under the RFS for the following year. The 2020 renewable fuel and 2021 biomass-based diesel volume requirements were published on February 6, 2020, increasing required volumes from 2019 requirements. The regulation is being challenged judicially in the D.C. Circuit, but the challenge was held in abeyance and remains unresolved. On December 7, 2021, EPA announced a series of actions setting biofuel volumes for 2020, 2021, and 2022, and introducing other regulatory changes. EPA also proposed to add a 250-million-gallon “supplemental obligation” to the volumes proposed for 2022 and stated its intent to add another 250 million gallons in 2023 to address the outcome of prior litigation. These volume proposals may be met with opposition, consistent with action taken regarding prior regulations. If successful, efforts to cause reductions or limitations on the requirement to blend renewable fuel would likely reduce the volume of RINs purchased to meet the RFS blending requirements. Further, there have been proposals to revise, and in some instances limit, the RFS program in the United States. As recently as October 2019, House Energy and Commerce Committee members, Representatives Shimkus and Flores, introduced the 21st Century Transportation Fuels Act that aims to eliminate volume-based renewable fuels mandates and instead rely upon the transition to a national octane standard and automobile manufacturing standards to govern fuel composition. This bill was referred to the Subcommittee on Environment and Climate Change in October 2019, but no further action has been taken.  Various parties have also sought for the executive branch to revise the RFS. Limiting or eliminating the RFS could have the effect of reducing or eliminating the volume of RINs required to meet blending requirements, which could adversely affect the demand for RINs and accordingly the revenue stream we have historically derived from the sale of RINs. ‎Further, uncertainty associated with RFS regulatory requirements may increase volatility of RIN prices, which may adversely affect our business.

The Renewable Fuels Regulations under the Canadian Environmental Protection Act, 1999 impose obligations on producers and importers of certain liquid petroleum fuels to acquire renewable fuel compliance units in connection with the fuels they produce or import. Compliance Units can be generated through the blending of renewable fuel into liquid petroleum fuels. Certain provincial jurisdictions in Canada also impose obligations to incorporate renewable fuels into fuels that are distributed within the jurisdiction.  The Canadian federal government is expected to publish final Clean Fuel Regulations under the Canadian Environmental Protection Act, 1999 in the spring of 2022. The Clean Fuel Regulations, as currently drafted, would replace the current Renewable Fuel Regulations over time, and would impose lifecycle carbon intensity requirements on producers and importers of certain liquid petroleum fuels and establish rules relating to the trading of compliance credits.  Carbon intensity requirements under the Clean Fuel Regulations would become more stringent over time.  The Clean Fuel Regulations were originally expected to come into force in December 2022.  At this time, we do not know how the new Clean Fuel Regulations in Canada will impact demand for our renewable fuel in Canada.

G.   Regulation of Naturally Occurring Radioactive Metals, or NORM

Certain states have enacted laws and regulations regulating NORM. In the course of our E&P waste operations, some of our equipment involved in E&P waste management and disposal may be exposed to naturally occurring radiation associated with oil and gas deposits. Further, certain E&P wastes we handle could be NORM contaminated. NORM wastes exhibiting levels of naturally occurring radiation exceeding established state standards are typically subject to special handling and disposal requirements, and any storage vessels, piping, equipment and work area affected by NORM waste may be subject to remediation or restoration requirements. It is possible that we may incur significant costs or liabilities associated with inadvertently handling NORM contaminated waste or equipment that becomes NORM contaminated based on exposure or contact with elevated levels of NORM.

H.   Extended Producer Responsibility, or EPR, Regulations

EPR regulations place responsibility on product manufacturers or suppliers to assume certain waste management or recycling responsibility for their products after such products’ useful life or otherwise impose obligations on product manufacturers or suppliers to reduce the volume of waste associated with their products.

EPR regulations have yet to be promulgated at the federal level in the United States, but have been promulgated or considered in state and local jurisdictions in the United States. For example, both Maine and Oregon enacted EPR legislation in 2021. These statutes require brands to provide funding to improve recycling infrastructure statewide.  EPR regulations could have an adverse effect on our business if enacted at the federal level or if widely enacted by state or local governments.

Numerous provincial jurisdictions in Canada have promulgated EPR and related waste diversion legislation and other programs that mandate or encourage recycling and waste reduction and restrict the landfill disposal of certain types of waste. The enactment of new and more stringent regulations reducing the types or volumes of wastes available for disposal in landfills could impact our future operations.

I. Right to Repair

President Joe Biden issued Executive Order 14036 on July 9, 2021, directing the Federal Trade Commission, or FTC, in the United States to draft regulations that limit the ability of original equipment manufacturers, or OEMs, to restrict independent repairs of their products. This order aims to reduce the amount of waste produced by electronics and other goods by reducing the cost to repair or refurbish damaged items rather than discarding them.  Similar regulatory initiatives have been proposed in Canada at the federal level and in some provinces.  If such rules are issued or new regulatory requirements come into force, demand for electronic waste disposal could be reduced, potentially representing a reduction in demand for our services.

J.  State Public Utility Regulation

In some states, public authorities regulate the rates that landfill operators may charge. The adoption of rate regulation or the reduction of current rates in states in which we own or operate landfills could adversely affect our business, financial condition and operating results.

RISK MANAGEMENT, INSURANCE AND FINANCIAL SURETY BONDS

Risk Management

We maintain environmental and other risk management programs that we believe are appropriate for our business. Our environmental risk management program includes evaluating existing facilities and potential acquisitions for environmental law compliance. We do not presently expect environmental compliance costs to increase materially above current levels, but we cannot predict whether future acquisitions will cause such costs to increase. We also maintain a worker safety program that encourages safe practices in the workplace. Operating practices at our operations emphasize

24

Table of Contents

minimizing the possibility of environmental contamination and litigation. Our risk management programs are designed, we believe, to ensure that our facilities are in material compliance with applicable federal, state and provincial regulations.

Insurance

We maintain an insurance program for automobile liability, general liability, employer’s liability claims, environmental liability, cyber liability, employment practices liability and directors’ and officers’ liability as well as for employee group health insurance, property and workers’ compensation. Our loss exposure for insurance claims is generally limited to per incident deductibles or self-insured retentions. Losses in excess of deductible or self-insured retention levels are insured subject to policy limits.

Under our current Company-wide insurance program, we carry per incident deductibles or self-insured retentions ranging from $250,000 to $2 million for cyber liability and directors’ and officers’ liability claims. Additionally, we have umbrella policies with insurance companies for automobile liability, general liability and employer’s liability. Our property insurance limits are in accordance with the replacement values of the insured property.

Under our current insurance program for our U.S. operations, we carry per incident deductibles or self-insured retentions ranging from $350,000 to $20 million for automobile liability claims, workers’ compensation and employer’s liability claims, general liability claims, employee group health insurance and employment practices liability, environmental liability, and for most property claims, subject to certain additional terms and conditions. Since workers’ compensation is a statutory coverage limited by the various state jurisdictions, the umbrella coverage is not applicable. Our environmental protection insurance policy covers all owned or operated landfills, certain transfer stations and other facilities, subject to the policy terms and conditions. From time to time, actions filed against us include claims for punitive damages, which are generally excluded from coverage under our liability insurance policies. Our policy provides insurance for new pollution conditions that originate after the commencement of our coverage. Pollution conditions existing prior to the commencement of our coverage, if found, could be excluded from coverage.

Under our current insurance program for our Canadian operations, we carry per incident deductibles or self-insured retentions ranging from $350,000 to $5.0 million for automobile liability claims, property claims, employment practices liability and environmental liability. Since workers’ compensation is a provincial coverage limited by the various province jurisdictions, the umbrella coverage is not applicable. Employees are eligible to receive health coverage under Canada’s public health care system and, in addition, most employees of our Canadian operations are eligible to participate in group medical and drug coverage plans sponsored by us. Our environmental protection insurance policy covers all owned or operated landfills, certain transfer stations and other facilities, subject to the policy terms and conditions. Our policy provides insurance for new pollution conditions that originate after the commencement of our coverage. Pollution conditions existing prior to the commencement of our coverage, if found, could be excluded from coverage.

Financial Surety Bonds

We use financial surety bonds for a variety of corporate guarantees. The financial surety bonds are primarily used for guaranteeing municipal contract performance and providing financial assurances to meet asset closure and retirement requirements under certain environmental regulations. In addition to surety bonds, such guarantees and obligations may also be met through alternative financial assurance instruments, including insurance, letters of credit and restricted cash and investment deposits. At December 31, 2021 and 2020, we had provided customers and various regulatory authorities with surety bonds in the aggregate amount of approximately $744.0 million and $727.4 million, respectively, to secure our asset closure and retirement requirements and $556.6 million and $482.3 million, respectively, to secure performance under collection contracts and landfill operating agreements.

We source financial surety bonds from a variety of third-party insurance and surety companies, including a company in which we own a 9.9% interest that, among other activities, issues financial surety bonds to secure landfill final capping, closure and post-closure obligations for companies operating in the solid waste sector.

SEASONALITY

Based on historic trends, excluding any impact from the COVID-19 pandemic or an economic recession, we would expect our operating results to vary seasonally, with revenues typically lowest in the first quarter, higher in the second and third quarters and lower in the fourth quarter than in the second and third quarters. This seasonality reflects (a) the lower volume of solid waste generated during the late fall, winter and early spring because of decreased construction and demolition activities during winter months in Canada and the U.S., and (b) reduced E&P activity during harsh weather conditions, with expected fluctuation due to such seasonality between our highest and lowest quarters of approximately 10%. In addition, some of our operating costs may be higher in the winter months. Adverse winter weather conditions slow waste collection activities, resulting in higher labor and operational costs. Greater precipitation in the winter increases the weight of collected MSW, resulting in higher disposal costs, which are calculated on a per ton basis.

Our ability to access the capital markets may be severely restricted at a time when we would like, or need, to do so. While we expect we will be able to fund some of our acquisitions with our existing resources, additional financing to pursue additional acquisitions may be required. However, particularly if market conditions deteriorate, we may be unable to secure additional financing or any such additional financing may not be available to us on favorable terms, which could have an impact on our flexibility to pursue additional acquisition opportunities. In addition, disruptions in the capital and credit markets could adversely affect our ability to draw on our credit facility or raise other capital. Our access to funds under the credit facility is dependent on the ability of the banks that are parties to the facility to meet their funding commitments. Those banks may not be able to meet their funding commitments if they experience shortages of capital and liquidity or if they experience excessive volumes of borrowing requests within a short period.

We may lose contracts through competitive bidding, early termination or governmental action.

We derive a significant portion of our revenues from market areas where we have exclusive arrangements, including franchise agreements, municipal contracts and certificates issued by Washington State known as G Certificates. Many franchise agreements and municipal contracts are for a specified term and are, or will be, subject to competitive bidding in the future. For example, we have approximately 492 contracts, representing approximately 3.1% of our annual revenues, which were set for expiration or automatic renewal on or before December 31, 2022. Although we intend to bid on existing contracts subject to competitive bidding in the future and additional municipal contracts and franchise agreements, we may not be the successful bidder, or we may need to lower our price in order to retain the contract. In addition, some of our customers, including municipalities, have and others may terminate their contracts with us before the end of the terms of those contracts. Similar risks may affect our contracts to operate municipally-owned assets, such as landfills.

Governmental action may also affect our exclusive arrangements. Municipalities may annex unincorporated areas within counties where we provide collection services. As a result, our customers in annexed areas may be required to obtain services from competitors that have been previously franchised by the annexing municipalities to provide those services. In addition, municipalities in which we provide services on a competitive basis may elect to franchise those services to other service providers. Unless we are awarded franchises by these municipalities, we will lose customers. Municipalities may also decide to provide services to their residents themselves, on an optional or mandatory basis, causing us to lose customers. If we are not able to replace revenues from contracts lost through competitive bidding or early termination or from the renegotiation of existing contracts with other revenues within a reasonable time, our revenues could decline. Municipalities sometimes also promulgate “flow control” laws and regulations requiring us to deliver waste we collect within a particular jurisdiction to facilities not owned or controlled by us, which could increase our costs and reduce our revenues.

Our financial and operating performance may be affected by the inability to renew landfill operating permits, obtain new landfills and expand existing ones.

We currently own and/or operate 97 landfills throughout the United States and Canada. Our ability to meet our financial and operating objectives depends in part on our ability to acquire, lease, or renew landfill operating permits, expand existing landfills and develop new landfill sites. It has become increasingly difficult and expensive to obtain required permits and approvals to build, operate and expand solid waste management facilities, including landfills and transfer stations. Although the process generally takes less time, the process of obtaining permits and approvals for E&P landfills has similar uncertainties. Operating permits for landfills in states and provinces where we operate must generally be renewed every five to ten years, although some permits are required to be renewed more frequently. These operating permits often must be renewed several times during the permitted life of a landfill. The permit and approval process is often time consuming, requires numerous hearings and compliance with zoning, environmental and other requirements. States and municipalities are also increasingly adopting requirements for environmental justice reviews as part of certain permitting decisions. These policies generally require permitting agencies to give heightened attention to the potential for projects to disproportionately impact low-income and minority communities.  The permitting and approval process is frequently challenged by special interest and other groups, including those utilizing social media to further their objectives, and may result in the denial of a permit or renewal, the award of a permit or renewal for a shorter duration than we believed was otherwise required by law, or burdensome terms and conditions being imposed on our operations. For example, see the discussions regarding the Los Angeles County, California Landfill Expansion Litigation—A. Chiquita Canyon, LLC Lawsuit Against Los Angeles County in Note 13, “Commitments and Contingencies,” of our consolidated financial

statements included in Item 8 of this Annual Report on Form 10-K. This process may be further complicated by the COVID-19 pandemic, which has and may continue to impact the timeliness of the receipt of approvals and permits.  We may not be able to obtain new landfill sites or expand the permitted capacity of our existing landfills when necessary, and may ultimately be required to expense up to the carrying value of the landfill or expansion project, less the recoverable value of the property and other amounts recovered. Obtaining new landfill sites is important to our expansion into new, non-exclusive solid waste markets and in our E&P waste business. If we do not believe that we can obtain a landfill site in a non-exclusive market, we may choose not to enter that market. Expanding existing landfill sites is important in those markets where the remaining lives of our landfills are relatively short. We may choose to forego acquisitions and internal growth in these markets because increased volumes would further shorten the lives of these landfills. Any of these circumstances could adversely affect our operating results.

Increases in labor costs and limitations on labor availability could impact our financial results.

Labor is one of our highest costs and relatively small increases in labor costs per employee could materially affect our cost structure.  A shortage of qualified employees in our markets, including due to the COVID-19 pandemic, would require us to incur additional costs related to wages and benefits, including, for example, our targeted minimum wage increase to $15 per hour (CAD $16 per hour in Canada), to hire more expensive temporary employees or to contract for services with more expensive third-party vendors.  In addition, higher turnover can result in increased costs associated with recruiting and training; it can also impact operating costs, including maintenance and risk.  As a result of the COVID-19 pandemic and subsequent labor constraints, we have experienced increased competition with other businesses in our markets for qualified employees as a result of the labor supply being tight in our markets, which has driven higher turnover and increased the time it takes to fill job openings. Moreover, as an essential services provider, in March 2020 we implemented temporary emergency wages, supplemental pay and extended benefits programs for our frontline workforce and other employees directly or indirectly affected by the COVID-19 pandemic, which were partially offset by cost reductions in other areas.

Increases in capital expenditures could impact our financial results.

Increases in fleet, equipment and landfill construction costs due to cost pressures, acquisitions and new contracts could result in capital expenditures being higher than anticipated. In addition, supply chain disruptions and inflationary pressures, including those related to the COVID-19 pandemic, have and are expected to continue to result in higher costs, delays or lack of availability of fleet, equipment or supplies. This could impact our ability to generate free cash flow in line with our expectations or otherwise adversely affect our financial results.

The level of exploration, development and production activity of E&P companies will impact the demand for our E&P waste services.

The value of crude oil has impacted and may in the future impact the level of drilling activity in the basins where we operate; however, we cannot provide assurances that higher crude oil prices will result in increased capital spending and linear feet drilled by our customers in the basins where we operate.  The level of investment and the amount of linear feet drilled in the basins where we operate may impact the ability of E&P companies to access capital on economically advantageous terms or at all. In addition, E&P companies may elect to decrease investment in basins where the returns on investment are inadequate or uncertain due to lower crude oil prices or volatility in crude oil prices.  Energy transition, or a transformation of the global energy sector from fossil-based systems of energy production and consumption to renewable energy sources, could also affect investments by E&P companies in the basins where we operate. See the section Impairments of Property and Equipment and Finite-Lived Intangible Assets in Note 3, “Summary of Significant Accounting Policies,” of our consolidated financial statements included in Item 8 of this Annual Report on Form 10-K regarding the impairment charges recorded during the years ended December 31, 2021 and 2020 on property and equipment in our E&P waste operations.

A portion of our growth and future financial performance depends on our ability to integrate acquired businesses, and the performance of our acquisitions.

A component of our growth strategy involves achieving economies of scale and operating efficiencies by growing through acquisitions. We may not achieve these goals unless we effectively combine the operations of acquired businesses with our existing operations. Similar risks may affect contracts that we are awarded to operate municipally-owned assets, such as landfills. In addition, we are not always able to control the timing of our acquisitions. Our inability to complete acquisitions within the time frames that we expect may cause our operating results to be less favorable than expected, which could cause our share price to decline.  In addition, we may change our strategy with respect to a market or acquired businesses and decide to sell such operations at a loss, or keep those operations and recognize an impairment of goodwill and/or intangible assets. Similar risks may affect contracts that we are awarded to operate municipally-owned assets, such as landfills.

Some acquisitions may not fulfill our anticipated financial or strategic objectives in a given market due to factors that we cannot control, such as market conditions, including the price of crude oil, market position, competition, customer base, loss of key employees, third-party legal challenges or governmental actions. In addition, acquisitions may have liabilities or risks that we fail or are unable to discover, or that become more adverse to our business than we anticipated at the time of acquisition. As a successor owner, we may be legally responsible for those liabilities that arise from businesses that we acquire, whether we expressly assume them or not, including as a result of sellers not having sufficient funds to perform their obligations or liabilities being imposed on us under various regulatory schemes and other applicable laws. In addition, our insurance program may not cover such sites and will not cover liabilities associated with some environmental issues that may have existed prior to attachment of coverage. For example, see the discussions regarding the Lower Duwamish Waterway Superfund Site Allocation Process in Note 13, “Commitments and Contingencies,” of our consolidated financial statements included in Item 8 of this Annual Report on Form 10-K. A successful uninsured claim against us could harm our financial condition or operating results. Additionally, there may be other risks of which we are unaware that could have an adverse effect on businesses that we acquire or have acquired, such as foreign, state, provincial and local regulation and administrative risks. Another example of risk is interested parties that may bring actions against us in connection with operations that we acquire or have acquired. Furthermore, risks or liabilities we judge to be not material or remote at the time of acquisition may develop into more serious risks to our business. Any adverse outcome resulting from such risks or liabilities could harm our operations and financial results and create negative publicity, which could damage our reputation, competitive position and share price.

The seasonal nature of our business and “event-driven” waste projects cause our results to fluctuate.

Based on historic trends, excluding any impact from the COVID-19 pandemic or an economic recession, we would expect our operating results to vary seasonally, with revenues typically lowest in the first quarter, higher in the second and third quarters, and lower in the fourth quarter than in the second and third quarters. We expect the fluctuation in our revenues between our highest and lowest quarters to be approximately 10%. This seasonality reflects the lower volume of solid waste generated during the late fall, winter and early spring because of decreased construction and demolition activities during the winter months in Canada and the U.S., and reduced E&P activity during harsh weather conditions. Conversely, mild winter weather conditions may reduce demand for oil and natural gas, which may cause our customers to curtail their drilling programs, which could result in production of lower volumes of E&P waste.

Adverse winter weather conditions, including severe storms or extended periods of inclement weather, slow waste collection activities, resulting in higher labor and operational costs. Greater precipitation in the winter increases the weight of collected solid waste, resulting in higher disposal costs, which are calculated on a per ton basis. Certain weather conditions, including severe storms, may result in temporary suspension of our operations, which can significantly impact the operating results of the affected areas. Conversely, weather-related occurrences and other “event-driven” waste projects can boost revenues through heavier weight loads or additional work for a limited time. These factors impact period-to-period comparisons of financial results, and our share price may be negatively affected by these variations.

Our results will be affected by changes in recycled commodity prices and quantities.

We provide recycling services to some of our customers. The recyclables we process for sale include paper products and plastics that are shipped primarily to customers in the United States, as well as other markets, including Asia. The sale prices of and the demand for recyclable commodities are frequently volatile and when they decline, our revenues, operating results and cash flows will be affected. The value of recyclables may be impacted by factors including: changes to international waste importation and exportation laws; quality concerns; the volatility of crude oil prices, which impacts plastic; and, the demand for paper products, which impacts fiber, along with the extent to which manufacturers rely on recycled feedstock.

Singlestream recycling facilities process a wide range of commingled materials and tend to receive a higher percentage of non-recyclables, particularly in residential collection, which results in increased processing and residual disposal costs to achieve quality standards. As a result, we have increased the fees that we charge customers at our recycling facilities in order to recover the higher processing costs for recyclables.  This may result in lower recycled commodity volumes at our recycling facilities, as customers may elect to pursue cheaper alternatives for processing or disposal.  Any such reduction could impact revenues, operating results and cash flow.  Some of our recycling operations offer rebates to customers based on the market prices of commodities we buy to process for resale. Therefore, if we recognize increased revenues resulting from higher prices for recyclable commodities, the rebates we pay to suppliers will also increase, which also may impact our operating results.  To the extent that there is an economic slowdown, including the one associated with the COVID-19 pandemic, a resulting decline in demand for recycled commodities has and could in the future impact our revenues, operating results and cash flow.

Our results will be affected by changes in the value of renewable fuels.

Variations in the price of methane gas and other energy-related products that are marketed and sold by our landfill gas recovery operations affect our results. Pursuant to the Energy Independence and Security Act of 2007, the United States EPA has promulgated the Renewable Fuel Standards, or RFS, which require refiners to either blend "renewable fuels," such as ethanol and biodiesel, into their transportation fuels or to purchase renewable fuel credits, known as renewable identification numbers, or RINs, in lieu of blending. In some cases, landfill gas generated at our landfills in the United States and Canada qualifies as a renewable fuel for which RINs are available. The price of RINs has been extremely volatile and is dependent upon a variety of factors, including potential legislative changes, the availability of RINs for purchase, the demand for RINs, which is dependent on transportation fuel production levels, the mix of the petroleum business’ petroleum products and fuel blending performed at the refineries and downstream terminals, all of which can vary significantly from period to period. In addition, demand for RINs can be impacted by the ability of refineries to obtain small refinery exemptions, or SREs, through the EPA.  Any reductions or limitations on the requirement to blend renewable fuel and any related waivers including SREs, would likely reduce the demand for RINs, which could impact the value of RINs.  At this time, we do not know how the new Clean Fuel Regulations in Canada, as discussed above, will impact the demand for our renewable fuel in the future.

A significant reduction in the value of RINs in the United States or the price paid for our renewable fuel in Canada could adversely impact our reported results.  To manage a portion of this risk, we may enter into contractual agreements to sell RINs at a fixed price.  As of December 31, 2021 our existing agreements to sell RINs at a fixed price reached maturity and we currently have no contractual fixed price agreements in place.

Climate change, including adverse weather conditions, could adversely affect our operations and increase operational costs.

Our operations and assets are subject to risks associated with the effects of climate change and adverse weather conditions. Risks associated with climate change, such as increased frequency and/or intensity of weather events, flooding, wildfires, sea level rise, and other weather- and climate-related events could negatively impact our operations. For example, these events could disrupt or result in suspension of collection activities, disrupt landfill and transfer station operations, or hinder landfill development or expansion. It is also possible that these events could disrupt our customers’ businesses, thereby reducing the amount of waste generated by their operations. Additional laws and regulations related

35

to climate change could also be promulgated, which could result in increased operational costs or disruption to our clients’ business, thereby impacting our operational results and financial condition.

Increases in insurance costs and the amount that we self-insure for various risks or limitations of our insurance coverage could reduce our operating margins and reported earnings.

We maintain insurance policies for automobile, general, employer’s, environmental, cyber, employment practices and directors’ and officers’ liability as well as for employee group health insurance, property insurance and workers’ compensation. We carry umbrella policies for certain types of claims to provide excess coverage over the underlying policies and per incident deductibles or self-insured retentions. The amounts that we effectively self-insure could cause significant volatility in our operating margins and reported earnings based on the event and claim costs of incidents, accidents, injuries and adverse judgments. Our insurance accruals are based on claims filed and estimates of claims incurred but not reported and are developed by our management with assistance from our third-party actuary and our third-party claims administrator. To the extent these estimates are inaccurate, we may recognize substantial additional expenses in future periods that would reduce operating margins and reported earnings. Furthermore, while we maintain liability insurance, our insurance is subject to coverage limitations. If we were to incur substantial liability on a covered claim, our insurance coverage may be inadequate to cover the entirety of such liability. This could have a material adverse effect on our financial position, results of operations and cash flows. One form of coverage limitation concerns claims for punitive damages, which are generally excluded from coverage under all of our liability insurance policies. A punitive damage award could have an adverse effect on our reported earnings in the period in which it occurs. Significant increases in premiums on insurance that we retain, as well as higher deductibles or self-insured retentions, could reduce our margins.

Increases in the price of diesel or compressed natural gas fuel may adversely affect our collection business and reduce our operating margins.

The market price of diesel fuel is volatile. We generally purchase diesel fuel at market prices, and such prices have fluctuated significantly in recent years. A significant increase in market prices for fuel, as experienced recently, could adversely affect our waste collection business through a combination of higher fuel and disposal-related transportation costs and reduce our operating margins and reported earnings. To manage a portion of this risk, we have entered into fixed-price fuel purchase contracts. During periods of falling diesel fuel prices, it may become more expensive to purchase fuel under fixed-price fuel purchase contracts than at market prices as the prices under our fixed-price fuel purchase contracts may be above market prices.

We utilize compressed natural gas, or CNG, in a small percentage of our fleet and we may convert more of our fleet from diesel fuel to CNG over time. The market price of CNG is also volatile; a significant increase in such cost could adversely affect our operating margins and reported earnings.

Our accruals for our landfill site closure and post-closure costs may be inadequate.

We are required to pay capping, closure and post-closure maintenance costs for landfill sites that we own and operate as well as for landfills we operated under life-of-site agreements. Our obligations to pay closure or post-closure costs may exceed the amount we have accrued and reserved and other amounts available from funds or reserves established to pay such costs. In addition, the completion or closure of a landfill site does not end our environmental obligations. After completion or closure of a landfill site, there exists the potential for unforeseen environmental problems to occur that could result in substantial remediation costs or potential litigation. The potential increased regulation of per- and polyfluoroalkyl substances (“PFAS”), bisphenol A (“BPA”) phthalates, methane and other emerging contaminants could result in greater expenditures for closure and post-closure costs. It is also possible that accruals may need to be expanded and that costs incurred related to these activities could be accelerated. Paying additional amounts for closure or post-closure costs and/or for environmental remediation and/or for litigation could harm our financial condition, operating results, or cash flow.

Our financial results could be adversely affected by impairments of goodwill, indefinite-lived intangibles or property and equipment.

As a result of our acquisition strategy, we have a material amount of goodwill, indefinite-lived intangibles and property and equipment recorded in our financial statements. We do not amortize our existing goodwill or indefinite-lived intangibles and are required to test goodwill and indefinite-lived intangibles for impairment annually in the fourth quarter of the year and whenever events or changes in circumstances indicate that the carrying value of goodwill and/or indefinite-lived intangible assets may not be recoverable using the one-step process prescribed in the accounting guidance. The process screens for and measures the amount of the impairment, if any. The recoverability of property and equipment is tested for impairment whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. Application of the impairment test requires judgment. A significant deterioration in a key estimate or assumption or a less significant deterioration to a combination of assumptions could result in an additional impairment charge in the future, which could have a significant adverse impact on our reported results. See the sections Goodwill and Indefinite-Lived Intangible Assets and Impairments of Property and Equipment and Finite-Lived Intangible Assets in Note 3, “Summary of Significant Accounting Policies,” of our consolidated financial statements included in Item 8 of this Annual Report on Form 10-K regarding the impairment charges recorded during the years ended December 31, 2021 and 2020 on indefinite-lived intangible assets, definite-lived intangible assets and property and equipment in our E&P waste operations.  

Our indebtedness could adversely affect our financial condition and limit our financial flexibility.

As of December 31, 2021, we had approximately $5.102 billion of total indebtedness outstanding, and we may incur additional debt in the future. This amount of indebtedness could:

In addition, a portion of our indebtedness, including interest rate swaps, is at variable rates which are based on the London Interbank Offered Rate, or LIBOR, which is expected to no longer be published after June 2023. The FASB added the Secured Overnight Financing Rate, or SOFR, as an eligible benchmark interest rate in order to facilitate the LIBOR to SOFR transition and provide sufficient lead time for entities to prepare for changes to interest rate risk hedging strategies for both risk management and hedge accounting purposes. In December 2021, the Canadian Alternative Reference Rate, or CARR, working group has recommended to cease publication of all Canadian Dollar Offered Rate, or CDOR, tenors after June 2024. We are developing a plan to transition our indebtedness from LIBOR to SOFR, and, in some cases, have already modified agreements to provide for the expected transition to SOFR.

Our ability to execute our financial strategy and our ability to 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. 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.

Further, our outstanding indebtedness is subject to financial and other covenants, which may be affected by changes in economic or business conditions or other events that are beyond our control, including the impacts from the COVID-19

pandemic.  If we fail to comply with the covenants under any of our indebtedness, we may be in default under the indebtedness, which may entitle the lenders or holders of indebtedness to accelerate the debt obligations. A default under one of our loans or debt securities could result in cross-defaults under our other indebtedness. In order to avoid defaulting on our indebtedness, we may be required to take actions such as reducing or delaying capital expenditures, reducing or eliminating dividends or share repurchases, selling assets, restructuring or refinancing all or part of our existing debt, or seeking additional equity capital, any of which may not be available on terms that are favorable to us, if at all.

We may be unable to obtain performance or surety bonds, letters of credit or other financial assurances or to maintain adequate insurance coverage.

If we are unable to obtain performance or surety bonds, letters of credit or insurance, we may not be able to enter into additional solid waste or other collection contracts or retain necessary landfill operating permits. Collection contracts, municipal contracts, transfer station operations and landfill closure and post-closure obligations may require performance or surety bonds, letters of credit or other financial assurance to secure contractual performance or comply with federal, state, provincial or local environmental laws or regulations. We typically satisfy these requirements by posting bonds or letters of credit. As of December 31, 2021, we had $1.301 billion of such surety bonds in place and $125.8 million of letters of credit issued and outstanding. Closure bonds are difficult and costly to obtain. If we are unable to obtain performance or surety bonds or additional letters of credit in sufficient amounts or at acceptable rates, we could be precluded from entering into additional collection contracts or obtaining or retaining landfill operating permits. Any future difficulty in obtaining insurance also could impair our ability to secure future contracts that are conditional upon the contractor having adequate insurance coverage. Accordingly, our failure to obtain performance or surety bonds, letters of credit or other financial assurances or to maintain adequate insurance coverage could limit our operations or violate federal, state, provincial, or local requirements, which could have a materially adverse effect on our business, financial condition and results of operations.

Alternatives to landfill disposal may cause our revenues and operating results to decline.

Counties and municipalities in which we operate landfills may be required to formulate and implement comprehensive plans to reduce the volume of MSW deposited in landfills through waste planning, composting, recycling or other programs, while working to reduce the amount of waste they generate. Some state, provincial and local governments mandate diversion, recycling and waste reduction at the source and prohibit the disposal of certain types of wastes, such as yard waste, food waste and electronics, at landfills. Even where not prohibited by state, provincial or local law, some grocery stores and restaurants have chosen to divert their organic waste from landfills, while other companies have set zero-waste goals and communicated an intention to cease the disposal of any waste in landfills. Although such actions are useful to protect our environment, these actions, as well as the actions of our customers to reduce waste or seek disposal alternatives, have reduced and may in the future further reduce the volume of waste going to landfills in certain areas, which may affect our ability to operate our landfills at full capacity and could adversely affect our operating results.

Labor union activity could divert management attention and adversely affect our operating results.

From time to time, labor unions attempt to organize our employees, and these efforts are likely to continue in the future. Certain groups of our employees are represented by unions, and we have negotiated collective bargaining agreements with most of these unions. Additional groups of employees may seek union representation in the future. As a result of these activities, we may be subjected to unfair labor practice charges, grievances, complaints and other legal and administrative proceedings initiated against us by unions or federal, state or provincial labor boards, which could negatively impact our operating results. Negotiating collective bargaining agreements with these unions could divert our management’s attention, which could also adversely affect our operating results. If we are unable to negotiate acceptable collective bargaining agreements, we might have to wait through “cooling off” periods, which may be followed by work stoppages, including strikes or lock-outs. Depending on the type and duration of any such labor disruptions, our operating expenses could increase significantly, which could adversely affect our financial condition, results of operations and cash flows.

We could face significant withdrawal liability if we withdraw from participation in one or more multiemployer pension plans in which we participate and the accrued pension benefits are not fully funded.

We participate in 15 “multiemployer” pension plans administered by employee and union trustees. We make periodic contributions to these plans to fund pension benefits for our union employees pursuant to our various contractual obligations to do so. In the event that we withdraw from participation in or otherwise cease our contributions to one of these plans, then applicable law regarding withdrawal liability could require us to make additional contributions to the plan if the accrued benefits are not fully funded, and we would have to reflect that “withdrawal liability” as an expense in our consolidated statement of operations and as a liability on our consolidated balance sheet. Our withdrawal liability for any multiemployer plan would depend on the extent to which accrued benefits are funded. In the ordinary course of our renegotiation of collective bargaining agreements with labor unions that participate in these plans, we may decide to discontinue participation in a multiemployer plan, and in that event, we could face withdrawal liability. Some multiemployer plans in which we participate may from time to time have significant accrued benefits that are not funded. The size of our potential withdrawal liability may be affected by the level of unfunded accrued benefits, the actuarial assumptions used by the plan and the investment gains and losses experienced by the plan.

We have established long-term, aspirational targets associated with sustainability-related investments and projects which may or may not be achieved.

‎Stakeholder input, business considerations, and potential regulation have reinforced the ‎importance of developing and implementing ESG and sustainability initiatives. In 2020, we ‎adopted long-term, aspirational sustainability targets and committed over $500 million for investments and ‎projects to these efforts.  Our ability to achieve these targets will depend significantly on, among other ‎things, the success of these investments and projects and our ability to meet our financial and ‎operating objectives, which can be impacted by the numerous risks and uncertainties associated with ‎our business and the industry in which we operate.  There is a risk that some or all of the expected ‎benefits of these investments and projects may fail to materialize, may cost more to achieve or may ‎not occur within the anticipated time periods. In addition, there is a risk that the actions taken by us to ‎achieve these targets may have a negative impact on our existing business and increase capital ‎expenditures, which could adversely affect our operating results. Our failure to achieve these targets, ‎or a perception among key stakeholders that such targets are insufficient or unattainable, could ‎damage our reputation, competitive position and share price.‎

There is increasing interest in companies developing and implementing more robust ‎environmental, social, and governance policies and practices and disclosure around climate-related risk ‎identification and mitigation.  In addition, certain investors and lenders are incorporating ESG factors ‎into their investment or lending process, alongside traditional financial considerations. Developing and ‎implementing policies and practices, and developing additional disclosure in relation to climate change ‎and other environmental and social risk issues, can involve significant costs and require a significant ‎time commitment from our Board of Directors, management and employees.  In addition, our failure ‎to implement such policies, practices and disclosure could adversely affect our reputation, competitive ‎position and share price and our ability to raise capital, even if our operating results or prospects have ‎not changed.‎

Our Company published its 2021 Sustainability Report, available at ‎www.wasteconnections.com/sustainability, to communicate our efforts to our ‎investors and stakeholders. The 2021 Sustainability Report does not constitute part of, and is not incorporated by reference into, this Annual Report on Form 10-K or any other report we provide to the SEC or other securities regulators.

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

Providing environmental and waste management services, including constructing and operating landfills, involves risks such as truck accidents, equipment defects, malfunctions and failures.  We are also an essential services provider, and our frontline employees have continued to provide services during the COVID-19 pandemic amid related mandatory and voluntary closures, shelter-in-place orders, and similar government restrictions on or advisories with respect to travel, business operations and public gatherings, which could involve additional risks.  Additionally, we closely monitor and manage landfills to minimize the risk of waste mass instability and releases of hazardous materials or odors that could be

39

Table of Contents

triggered by weather or natural disasters.  There may also be risks presented by the potential for subsurface chemical reactions causing elevated landfill temperatures.

We also 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 involves additional risks of fire and explosion. Any of these risks could potentially result in injury or death of employees and others, a need to shut down or reduce operation of facilities, increased operating expense and exposure to liability for pollution and other environmental damage, and property damage or destruction.

While we seek to minimize our exposure to such risks through comprehensive training, compliance and response and recovery programs, as well as vehicle and equipment maintenance programs and the use of personal protective equipment, if we were to incur substantial liabilities in excess of any applicable insurance coverage, 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, 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 depend significantly on the services of the members of our senior and regional management team, and the departure of any of those persons could cause our operating results to suffer.

Our success depends significantly on the continued individual and collective contributions of our senior and regional management team. The loss of the services of any member of our senior and regional management, including as a result of the COVID-19 pandemic, or the inability to hire and retain experienced management personnel could harm our operating results.

Our decentralized decision-making structure could allow local managers to make decisions that may adversely affect our operating results.

We manage our operations on a decentralized basis. Local managers have the authority to make many decisions concerning their operations without obtaining prior approval from executive officers, subject to compliance with general company-wide policies. Poor decisions by local managers could result in the loss of customers or increases in costs, in either case adversely affecting operating results.

General Risk Factors

Our results are vulnerable to economic conditions.

Our business and results of operations may be adversely affected by changes in national or global economic conditions, including the price of crude oil.

In an economic slowdown, we may experience the negative effects of the following, any of which could negatively impact our operating income and cash flows: decreased waste generation, increased competitive pricing pressure, increased customer turnover, and reductions in customer service requirements.  In a recessionary environment, two of our business lines that could see a more immediate impact are construction and demolition debris and E&P waste disposal, as demand for new construction or energy exploration decreases.  Our commercial and industrial collection activity and the related demand for our landfill disposal and other services may also be impacted, depending on the drivers of the economic slowdown.  In addition, a weaker economy may result in declines in recycled commodity prices.  Worsening economic conditions or a prolonged or recurring economic recession could adversely affect our operating results and expected seasonal fluctuations.  Further, we cannot assure you that any improvement in economic conditions after such a slowdown will result in an immediate, if at all, positive improvement in our operating results or cash flows.

Public health crises and the effects of related governmental initiatives have adversely affected and may continue to adversely affect our business, financial condition and results of operations.

Public health crises, such as the COVID-19 pandemic, may impact our operations or our customers’ operations in ways that adversely affect our business, results of operations and financial condition.  The COVID-19 pandemic has resulted in adverse impacts to our business.  Fear of such events and their duration and spread might also alter consumer confidence, behavior and spending patterns, resulting in an economic slowdown that could continue to affect demand for our services.  Potential contributing factors include:

The ultimate extent of the impact of the COVID-19 pandemic on our business, results of operations, financial condition and cash flows will depend largely on future developments, including the duration and spread of the outbreak in the U.S. and Canada, its severity, the actions to contain the novel coronavirus or treat its impact, including the distribution, acceptance and effectiveness of vaccines, the severity of COVID-19 variants, and how quickly and to what extent normal economic and operating conditions can resume, all of which are uncertain and cannot be predicted at this time.

Our financial results are based upon estimates and assumptions that may differ from actual results.

In preparing our consolidated financial statements in accordance with U.S. generally accepted accounting principles, or GAAP, estimates and assumptions are made that affect the accounting for and recognition of assets, liabilities, revenues and expenses. These estimates and assumptions must be made because certain information that is used in the preparation of our financial statements is dependent on future events, cannot be calculated with a high degree of precision from data available or is not capable of being readily calculated based on generally accepted methodologies.  In some cases, including those resulting from the COVID-19 pandemic and associated impacts, these estimates are particularly difficult to determine and we must exercise significant judgment.  The most difficult, subjective and complex estimates and the assumptions that deal with the greatest amount of uncertainty are related to our accounting for landfills, self-insurance accruals, income taxes, allocation of acquisition purchase price, asset impairments and litigation, claims and assessments. Actual results for all estimates could differ materially from the estimates and assumptions that we use, which could have an adverse effect on our financial condition and results of operations.

Income taxes may be uncertain.

Our actual effective tax rate may vary from our expectation and that variance may be material. Tax interpretations, regulations and legislation in the various jurisdictions in which we and our affiliates operate are subject to measurement uncertainty and the interpretations can impact net income, income tax expense or recovery, and deferred income tax assets or liabilities. In addition, tax rules and regulations, including those relating to foreign jurisdictions, are subject to interpretation and require judgment by us that may be challenged by the taxation authorities upon audit.

Changes in our tax provision or an increase to our tax liabilities, whether due to legislation commonly referred to as the Tax Cut and Jobs Act (“Tax Act”) or interpretations of the Tax Act, such as through final regulations and the potential reversal of its provisions by a new federal administration, or a final determination of tax audits or otherwise, could have a material adverse effect on our financial position, results of operations, and cash flows.

Future changes to U.S., Canadian and foreign tax laws could materially adversely affect us.

We cannot give any assurance as to what our effective tax rate will be in the future, because of, among other things, uncertainty regarding the tax policies of the jurisdictions where we operate.

For example, the U.S. Congress, the Canadian government, the Organisation for Economic Co-operation and Development (“OECD”) and other government agencies in jurisdictions where we and our affiliates do business have had an extended focus on issues related to the taxation of multinational corporations. One example is in the area of base erosion and profit shifting (“BEPS”), where payments are made between affiliates from a jurisdiction with high tax rates to a jurisdiction with lower tax rates. In 2019, Canada ratified the Multilateral Convention to Implement Tax Treaty Related Measures to Prevent Base Erosion and Profit Shifting, or the MLI, as part of the OECD/G20 initiative to counter what was perceived as base erosion and profit shifting. The MLI entered into force in Canada on December 1, 2019 and entered into effect with respect to certain of Canada’s tax treaties on January 1, 2020 for withholding taxes and with respect to certain other taxes (including capital gains taxes) for tax years beginning on or after June 1, 2020 (which, for us and our affiliates, in general, was January 1, 2021). The MLI may enter into effect at a later date for certain of Canada’s tax treaties with countries that have not yet completed their domestic procedures to cause the MLI to come into effect. The MLI does not impact the tax treaty between Canada and the U.S.  In addition, in the 2021 Canadian federal budget, the Canadian government indicated it would introduce measures consistent with the OECD's recommendations in the area of hybrid mismatch arrangements.  The international tax environment continues to change as a result of these and related tax policy initiatives and reforms.  Although the timing and methods of implementation vary, numerous countries have responded to the BEPS project by implementing, or proposing to implement, changes to tax laws and tax treaties, at a rapid pace.  As a result of these and other changes, the tax laws in the United States, Canada, and other countries in which we and our affiliates do business could change on a prospective or retroactive basis, and any such changes could adversely affect us and our affiliates.  As a result of the rapidly changing and increasingly complex tax environment, our cost of tax compliance may increase and adversely affect our business, financial condition and results of operations.

Our operations in Canada expose us to exchange rate fluctuations that could adversely affect our financial performance and our reported results of operations.

Our operations in Canada are conducted primarily in Canadian dollars. Our consolidated financial statements are denominated in U.S. dollars, and to prepare those financial statements we must translate the amounts of the assets, liabilities, net sales, other revenues and expenses of our operations in Canada from Canadian dollars into U.S. dollars using exchange rates for the current period. Fluctuations in the exchange rates that are unfavorable to us, including those resulting from the impact of the COVID-19 pandemic, would have an adverse effect on our financial performance and reported results of operations.

Technology and Information Security Risks

We rely on computer systems to run our business and disruptions or privacy breaches in these systems could impact our ability to service our customers and adversely affect our financial results, damage our reputation, and expose us to litigation risk.

Our businesses rely on computer systems to provide customer information, process customer transactions and provide other general information necessary to manage our businesses. We also rely on a payment card industry-compliant third party to protect our customers’ credit card information. We have an active disaster recovery plan in place that we continuously review and test. However, our computer systems are subject to damage or interruption due to cybersecurity threats, system conversions, power outages, computer or telecommunication failures, catastrophic physical events such as fires, tornadoes and hurricanes and usage errors by our employees. Given the unpredictability of the timing, nature and scope of such disruptions, we could be potentially subject to operational delays and interruptions in our ability to provide services to our customers. Any disruption caused by the unavailability of our computer systems could adversely affect our revenues or could require significant investment to fix or replace them, and, therefore, could affect our operating results. In addition, cybersecurity attacks are evolving and include, but are not limited to, malicious software, attempts to gain unauthorized access to data and other electronic security breaches that could lead to disruptions in systems, unauthorized release of confidential or otherwise protected information and corruption of data. We are regularly the target of attempted cyber and other security threats and must continuously monitor and develop our information technology networks and infrastructure to prevent, detect, address and mitigate the risk of unauthorized access, misuse, computer viruses and other events that could have a security impact.

Further, as we pursue our acquisition growth strategy and pursue new initiatives that improve our operations and reduce our costs, we are also expanding and improving our information technologies, resulting in a larger technological presence and corresponding exposure to cybersecurity risk. If we fail to assess and identify cybersecurity risks associated with acquisitions and new initiatives, we may become increasingly vulnerable to such risks. Additionally, while we have implemented measures to prevent security breaches and cyber incidents, our preventative measures and incident response efforts may not be entirely effective. If our network of security controls, policy enforcement mechanisms or monitoring systems we use to address these threats to technology fail, the theft or compromise of confidential or otherwise protected company, customer or employee information, destruction or corruption of data, security breaches or other manipulation or improper use of our systems and networks could result in financial losses from remedial actions, business disruption, loss of business or potential liability, liabilities due to the violation of privacy laws and other legal actions, and damage to our reputation.

If we are not able to develop 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 may require that we develop or license, and protect, new technologies. We may experience difficulties or delays in the research, development, production and/or marketing of new products and services which may negatively impact our operating results and prevent us from recouping or realizing a return on the investments required to bring new products and services to market. Further, protecting our intellectual property rights and combating unlicensed copying and use of intellectual property is difficult, and any inability to obtain or protect new technologies could impact our services to customers and development of new revenue sources. Additionally, a competitor may develop or obtain exclusive rights to a “breakthrough technology” that claims to provide a revolutionary change in traditional waste management. If we have inferior intellectual property to our competitors, our financial results may suffer.

Legal, Regulatory and Compliance Risks

Extensive and evolving environmental, health and safety laws and regulations may restrict our operations and growth and increase our costs.

Existing environmental laws and regulations have become more stringently enforced in recent years. Further, with a new federal administration taking office in 2021 in the United States, it is possible that policies and initiatives of the prior

43

Table of Contents

administration could be reconsidered or even reversed, which could adversely affect our operating results. For example, a policy shift away from curtailment of regulation, narrowing Clean Water Act jurisdiction, or enabling oil and gas development on federal lands could adversely affect our business and our customers’ business. In addition, our industry is subject to regular enactment of new or amended federal, state, provincial and local environmental and health and safety statutes, regulations and ballot initiatives, as well as judicial decisions interpreting these requirements, which have become more stringent over time. Citizen suits brought pursuant to environmental laws as well as purported class actions based on public or private nuisance and negligence claims related to alleged landfill odor concerns have proliferated, along with the use of social media to drive such efforts. In addition, various state, provincial and local governments and the Canadian federal government have enacted, have the authority to enact or are considering enacting laws and regulations that restrict the movement or disposal within their jurisdictions of certain types of waste generated outside their jurisdictions. We expect these trends to continue, which could lead to material increases in our costs for future environmental, health and safety compliance. These requirements also impose substantial capital and operating costs and operational limitations on us and may adversely affect our business. In addition, federal, state, provincial and local governments may change the rights they grant to, the restrictions they impose on or the laws and regulations they enforce against, solid waste and E&P waste services companies. These changes could adversely affect our operations in various ways, including without limitation, by restricting the way in which we manage storm water runoff, comply with health and safety laws, treat and dispose of E&P or other waste or our ability to operate and expand our business.

Governmental authorities and various interest groups in the United States and Canada have implemented laws and regulations designed to limit greenhouse gas, or GHG, emissions in response to growing concerns regarding climate change. For example, the State of California, the Canadian federal government and several Canadian provinces have enacted climate change laws, and other states and provinces in which we operate are considering similar actions. The EPA made an endangerment finding in 2009 allowing certain GHGs to be regulated under the CAA. This finding allows the EPA to create regulations that will impact our operations – including imposing emission reporting, permitting, control technology installation and monitoring requirements, although the materiality of the impacts will not be known until all applicable regulations are promulgated and finalized. The Canadian federal government enacted the Greenhouse Gas Pollution Pricing Act in June 2018, which established a national carbon-pricing regime starting in 2019 for provinces and territories in Canada where there is no provincial regime in place or where the provincial regime does not meet the federal benchmark. The minimum national price on carbon in Canada is equivalent to CAD $50 per tonne CO2e in 2022.  The Canadian ‎federal government announced a plan to further increase the carbon price by CAD $15 per year starting in 2023, ‎reaching CAD $170 per tonne of CO2e by 2030. On November 19, 2020, the federal government introduced Bill C-12, the Canadian Net-Zero Emissions ‎Accountability Act, which establishes the framework for national GHG emissions reduction targets to attain net-zero ‎emissions by 2050. Several Canadian provinces have promulgated legislation and regulations to limit GHG emissions through requirements of specific controls, carbon levies, cap and trade programs or other measures. Comprehensive GHG legislation or regulation, including carbon pricing, affects not only our business, but also that of our customers.

Regulation of GHG emissions from oil and natural gas E&P operations may also increase the costs to our customers of developing and producing hydrocarbons, and as a result, may have an indirect and adverse effect on the amount of oilfield waste delivered to our facilities by our customers. These statutes and regulations increase the costs of our operations, and future climate change statutes and regulations may have an impact as well.

Further, governmental authorities have considered or have begun to implement increased regulation of PFAS and potentially other emerging contaminants, which could adversely affect our operations. The regulation of these substances could increase or accelerate our financial obligations associated with closure obligations, post-closure maintenance and other environmental remediation related to our solid waste facilities. Further, more stringent permitting obligations, including those relating to air and wastewater, as well as enhanced treatment of landfill leachate and landfill gas could adversely affect our operations in various ways, including without limitation, increased operational expenses as well as treatment and disposal costs, greater capital expenditures to meet control requirements, costs of compliance with permitting and health and safety requirements, and litigation risk.

44

Table of Contents

We may be subject in the normal course of business to judicial, administrative or other third-party proceedings that could interrupt or limit our operations, require expensive remediation, result in adverse judgments, settlements or fines and create negative publicity.

Governmental agencies may, among other things, impose fines or penalties on us relating to the conduct of our business, attempt to revoke or deny renewal of our operating permits, franchises or licenses for violations or alleged violations of environmental laws or regulations or as a result of third-party challenges, require us to install additional pollution control equipment or require us to remediate potential environmental problems relating to any real property that we or our predecessors ever owned, leased or operated or any waste that we or our predecessors ever collected, transported, disposed of or stored. Individuals, citizens groups, trade associations or environmental activists may also bring actions against us in connection with our operations that could interrupt or limit the scope of our business. Any adverse outcome in such proceedings could harm our operations and financial results and create negative publicity, which could damage our reputation, competitive position and share price.

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

We are, and from time to time become, involved in lawsuits, regulatory inquiries, and governmental and other legal proceedings arising out of the ordinary course of our business. Many of these matters raise complicated factual and legal issues and are subject to uncertainties and complexities, all of which make the matters costly to address. For example, in recent years, wage and employment laws have changed regularly and become increasingly complex, which has fostered litigation, including purported class actions. Similarly, purported class actions based on claims related to allegedly unlawful landfill odors and rates and fees charged under certain contracts for collection services have proliferated, as have citizen suits brought pursuant to environmental laws, such as those regulating the treatment of storm water runoff. The timing of the final resolutions to lawsuits, regulatory inquiries, and governmental and other legal proceedings is 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 consolidated financial condition, results of operations and cash flows. See discussion in Note 13, “Commitments and Contingencies,” of our consolidated financial statements included in Item 8 of this Annual Report on Form 10-K.

Extensive regulations that govern the design, operation, expansion and closure of landfills may restrict our landfill operations or increase our costs of operating landfills.

If we fail to comply with federal, state and provincial regulations, as applicable, governing the design, operation, expansion, closure and financial assurance of MSW, non-MSW and E&P waste landfills, we could be required to undertake investigatory or remedial activities, curtail operations or close such landfills temporarily or permanently. Future changes to these regulations, including an increased regulation of PFAS, may require us to modify, supplement or replace equipment or facilities at substantial costs.

If regulatory agencies fail to enforce these regulations vigorously or consistently, our competitors whose facilities are not forced to comply with the regulations may obtain an advantage over us. Our financial obligations arising from any failure to comply with these regulations could harm our business and operating results.

Liabilities for environmental damage may adversely affect our financial condition, business and earnings.

We may be liable for any environmental damage that our current or former operations cause, including damage to neighboring landowners or residents, particularly as a result of the contamination of soil, groundwater or surface water, and especially drinking water, or to natural resources. We may be liable for damage resulting from conditions existing before we acquired these operations. Even if we obtain legally enforceable representations, warranties and indemnities from the sellers of these operations, they may not cover the liabilities fully or the sellers may not have sufficient funds to perform their obligations.

We may also be liable for any on-site environmental contamination caused by pollutants or hazardous substances whose transportation, treatment or disposal we or our predecessors arranged or conducted. Some environmental laws and

45

Table of Contents

regulations may impose strict, joint and several liability in connection with releases of regulated substances into the environment. New or increased regulation of substances, such as PFAS or other emerging contaminants, could also lead to increased or previously unauthorized remediation costs or litigation risk.  Therefore, in some situations we could be exposed to liability as a result of our conduct that was lawful at the time it occurred or the conduct of, or conditions caused by, third parties, including our predecessors. If we were to incur liability for environmental damage, environmental clean-ups, corrective action or damage not covered by insurance or in excess of the amount of our coverage, our financial condition or operating results could be materially adversely affected. For example, see the discussion regarding the Lower Duwamish Waterway Superfund Site Allocation Process in Note 13, “Commitments and Contingencies,” of our consolidated financial statements included in Item 8 of this Annual Report on Form 10-K.

landfills that have complementary collection routes that can use company-owned disposal capacity. Controlling the point of transfer from haulers to landfills has become increasingly important as landfills continue to close and disposal capacity moves farther from the collection markets it serves.

Generally, the most profitable operators within the solid waste industry are those companies that are vertically integrated or enter into long-term collection contracts. A vertically integrated operator will benefit from:  (1) the internalization of waste, which is bringing waste to a company-owned landfill; (2) the ability to charge third-party haulers tipping fees either at landfills or at transfer stations; and (3) the efficiencies gained by being able to aggregate and process waste at a transfer station prior to landfilling.

The demand for our E&P waste services depends on the continued demand for, and production of, oil and natural gas. Crude oil and natural gas prices historically have been volatile. Macroeconomic and geopolitical conditions, including a significant decline in oil prices driven by both surplus production and supply, as well as the decrease in demand caused by factors including the COVID-19 pandemic, have resulted in decreased levels of oil and natural gas exploration and production activity and a corresponding decrease in demand for our E&P waste services.  Additionally, across the industry there is uncertainty regarding future demand for oil and related services, as noted by several energy companies, many of whom are customers of our E&P waste operations.  These companies have written down the values of their oil and gas assets in anticipation of the potential for the decarbonization of their energy product mix given an increased global focus on reducing greenhouse gases and addressing climate change.  Such uncertainty regarding global demand has had a significant impact on the investment and operating plans of our E&P waste customers in the basins where we operate.  If the prices of crude oil and natural gas substantially decline, it could lead to declines in the level of production activity and demand for our E&P waste services, which could result in the recognition of additional impairment charges on our intangible assets and property and equipment associated with our E&P waste operations.  See the section Impairments of Property and Equipment and Finite-Lived Intangible Assets in Note 3, “Summary of Significant Accounting Policies,” of our consolidated financial statements included in Item 8 of this Annual Report on Form 10-K for a discussion of the impairment charges recorded during the years ended December 31, 2021 and 2020.

Executive Overview

We are an integrated solid waste services company that provides non-hazardous waste collection, transfer and disposal services, along with resource recovery primarily through recycling and renewable fuels generation, in mostly exclusive and secondary markets across 43 states in the U.S. and six provinces in Canada. Waste Connections also provides E&P waste services in several basins across the U.S., as well as intermodal services for the movement of cargo and solid waste containers in the Pacific Northwest.

We generally seek to avoid highly competitive, large urban markets and instead target markets where we can attain high market share either through exclusive contracts, vertical integration or asset positioning. In markets where waste collection services are provided under exclusive arrangements, or where waste disposal is municipally owned or funded or available at multiple municipal sources, we believe that controlling the waste stream by providing collection services under exclusive arrangements is often more important to our growth and profitability than owning or operating landfills. We also target niche markets, like E&P waste treatment and disposal services.

The COVID-19 Pandemic’s impact on our Results of Operations

March 11, 2021 marked the one year anniversary of COVID-19 being declared a global pandemic by the World Health Organization. The related economic disruptions largely associated with closures or restrictions put into effect following the onset of the COVID-19 pandemic in the first quarter of 2020 resulted in declines in solid waste commercial collection, transfer station and landfill volumes, and roll off activity. Throughout the remaining fiscal year 2020, solid waste revenue and reported volumes largely reflected the pace and shape of the closures and subsequent reopening activity, with the timing and magnitude of recovery varying by market. Reported solid waste volumes in 2020 turned slightly negative in the first quarter, were most negative in the second quarter, and showed sequential improvement during the second half of the year, finishing the year at negative 3.1% in the fourth quarter. In the first quarter of 2021, the final period to include comparisons to pre-COVID-19 activity levels on a year over year basis, solid waste volumes were down 3.2%.  In the second quarter of 2021, solid waste volumes increased sequentially by 9.6% to up 6.5% on a year over year basis, with

50

positive volumes in all regions. In the second half of 2021, volumes remained positive in spite of increasingly difficult year over year comparisons as a result of reopening activity in 2020.

The COVID-19 pandemic also contributed to the decline in demand for and the value of crude oil, which impacted E&P drilling activity and resulted in lower E&P waste revenue, with the quarterly run rate decreasing from approximately $60 million in the first quarter of 2020 to approximately $25 million through the first quarter of 2021.  On increased drilling activity in several active shale basins, E&P waste revenue increased to a quarterly run rate of approximately $35 million in the second half of 2021.

Since the onset of the COVID-19 pandemic, protecting the health, welfare and safety of our employees has been our top priority. Recognizing the potential for financial hardship and other challenges, we have looked to provide a safety net for our employees on issues of income and family health. To that end, since the onset of the pandemic through year-end 2021, we have incurred over $40 million in incremental COVID-19-related costs, primarily supplemental pay for frontline employees. We continue to support our employees and their families, including with certain costs continuing in early 2022 due to surges in cases related to certain variants.  The impact of the COVID-19 pandemic on our business, results of operations, financial condition and cash flows in future periods will depend largely on future developments, including the duration and spread of the outbreak in the U.S. and Canada, the rate of vaccinations, the severity of COVID-19 variants, the actions to contain such coronavirus variants, and how quickly and to what extent normal economic and operating conditions can resume.

As a result of the COVID-19 pandemic and subsequent reopening activity in 2021, we have also experienced an impact to our operating costs as a result of factors including supply chain disruptions and labor constraints, as demand has recovered and competition has increased.  As a result, we have incurred incremental costs associated with higher wages, increased overtime as a result of higher turnover, and increased reliance on third party services.  

2021 Financial Performance

The functional currency of the Company, as the parent corporate entity, and its operating subsidiaries in the United States is the U.S. dollar. The functional currency of the Company’s Canadian operations is the Canadian dollar. The reporting currency of the Company is the U.S. dollar. The Company’s consolidated Canadian dollar financial position is translated to U.S. dollars by applying the foreign currency exchange rate in effect at the consolidated balance sheet date. The Company’s consolidated Canadian dollar results of operations and cash flows are translated to U.S. dollars by applying the average foreign currency exchange rate in effect during the reporting period. The resulting translation adjustments are included in other comprehensive income or loss. Gains and losses from foreign currency transactions are included in earnings for the period.

Operating Results

Revenues in 2021 increased 13.0% to $6.151 billion from $5.446 billion in 2020. Acquisitions closed during, or subsequent to, the prior year, net of divestitures, accounted for $215.4 million in incremental revenues in 2021.   Excluding the impact of such acquisitions, revenues increased 9.0% due predominantly to higher internal growth in solid waste.  Solid waste internal growth was positive 8.4%, due to higher price increases, higher surcharges and higher volumes, which turned positive following the anniversary of the onset of the COVID-19 pandemic in the first quarter. Pricing growth was 5.0%, with core pricing up 4.7%, plus materials and environmental surcharges of positive 0.3%. Volumes increased  by 1.6% on increases in landfill and hauling volumes beginning in the second quarter, which reflected the prior year comparisons due primarily to the impact of the COVID-19 pandemic and subsequent reopening activity. Increases in the value of recycled commodities resulted in a 1.8% increase to internal solid waste growth. Increases in the value of renewable fuels resulted in an increase of 0.6% to overall growth; and lower E&P waste activity resulted in a 0.3% decrease to overall growth.

Net income attributable to Waste Connections increased 202.0% to $618.0 million in 2021, from $204.7 million in 2020.  In 2021, adjusted earnings before interest, taxes, depreciation and amortization, or adjusted EBITDA, a non-GAAP financial measure (refer to page 73 of this Annual Report on Form 10-K for a definition and reconciliation to Net income attributable to Waste Connections), increased 15.5% to $1.919 billion, from $1.662 billion in 2020. As a percentage of

51

Table of Contents

revenue, adjusted EBITDA increased from 30.5% in 2020, to 31.2% in 2021. This 0.7 percentage point increase was due to price-led organic growth in solid waste and the benefit of higher commodity-driven revenue, partially offset by lower E&P waste activity.  Adjusted net income attributable to Waste Connections, a non-GAAP financial measure (refer to page 74 of this Annual Report on Form 10-K for a definition and reconciliation to Net income attributable to Waste Connections), in 2021 increased 21.7% to $846.6 million from $695.8 million in 2020.

Adjusted Free Cash Flow

Net cash provided by operating activities increased 20.6% to $1.698 billion in 2021, from $1.409 billion in 2020. Capital expenditures for property and equipment increased from $597.1 million in 2020 to $744.3 million in 2021, an increase of $147.2 million, or 24.7%. Adjusted free cash flow, a non-GAAP financial measure (refer to page 72 of this Annual Report on Form 10-K for a definition and reconciliation to Net cash provided by operating activities), increased by $167.7 million to $1.010 billion in 2021, from $841.9 million in 2020. Adjusted free cash flow as a percentage of revenues was 16.4% in 2021, as compared to 15.5% in 2020.

Return of Capital and Distributions to Shareholders

In 2021, we distributed $559.2 million to shareholders through a combination of cash dividends and share repurchases.  We paid $220.2 million to shareholders through cash dividends declared by our Board of Directors, which also increased the quarterly cash dividend by 12.2%, from $0.205 to $0.23 per common share in October 2021. Cash dividends increased $20.3 million, or 10.2%, from $199.9 million in 2020 due to a 10.8% increase in the quarterly cash dividend declared by our Board of Directors in October 2020, followed by the additional increase in October 2021. Our Board of Directors intends to review the quarterly dividend during the fourth quarter of each year, with a long-term objective of increasing the amount of the dividend. In 2021, we also repurchased 3.004 million common shares at an aggregate cost of $339.0 million.  We expect the amount of capital we return to shareholders through share repurchases to vary depending on our financial condition and results of operations, capital structure, the amount of cash we deploy on acquisitions, expectations regarding the timing and size of acquisitions, the market price of our common shares, and overall market conditions. We cannot assure you as to the amounts or timing of future share repurchases or dividends. We have the ability under our Credit Agreement to repurchase our common shares and pay dividends provided that we maintain specified financial ratios.

Capital Position

We target a Leverage Ratio, as defined in our Credit Agreement, of approximately 2.5x – 3.0x total debt to EBITDA. The Leverage Ratio is a non-GAAP ratio (refer to page 74 of this Annual Report on Form 10-K for more information on this ratio). Higher EBITDA in 2021 more than offset the impact of higher debt, resulting in a decrease in our Leverage Ratio from 2.68x at December 31, 2020 to 2.50x at December 31, 2021.  Cash balances decreased from $617.3 million at December 31, 2020 to $147.4 million at December 31, 2021, and we had $933.8 million of remaining borrowing capacity under our Credit Agreement, which matures in July 2026.

Critical Accounting Estimates and Assumptions

The preparation of financial statements in conformity with GAAP requires estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses and related disclosures of contingent assets and liabilities in the consolidated financial statements. As described by the SEC, critical accounting estimates and assumptions are those that may be material due to the levels of subjectivity and judgment necessary to account for highly uncertain matters or the susceptibility of such matters to change, and that have a material impact on the financial condition or operating performance of a company. Such critical accounting estimates and assumptions are applicable to our reportable segments. Based on this definition, we believe the following are our critical accounting estimates.

Insurance liabilities. We maintain insurance policies for automobile, general, employer’s, environmental, cyber, employment practices and directors’ and officers’ liability as well as for employee group health insurance, property insurance and workers’ compensation. We carry umbrella policies for certain types of claims to provide excess coverage over the underlying policies and per incident deductibles or self-insured retentions. Our insurance accruals are based on claims filed and estimates of claims incurred but not reported and are developed by our management with assistance from

52

Table of Contents

our third-party actuary and third-party claims administrator. The insurance accruals are influenced by our past claims experience factors and by published industry development factors. If we experience insurance claims or costs above or below our historically evaluated levels, our estimates could be materially affected. The frequency and amount of claims or incidents could vary significantly over time, which could materially affect our self-insurance liabilities. Additionally, the actual costs to settle the self-insurance liabilities could materially differ from the original estimates and cause us to incur additional costs in future periods associated with prior year claims.

Income taxes. Deferred income tax assets and liabilities are determined based on differences between the financial reporting and income tax bases of assets and liabilities and are measured using the enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse. If our judgment and estimates concerning assumptions made in calculating our expected future income tax rates are incorrect, our deferred income tax assets and liabilities would change. Based on our deferred income tax liability balance at December 31, 2021, each 0.1 percentage point change to our expected future income tax rates would change our deferred income tax liability balance and income tax expense by approximately $3.3 million.

Accounting for landfills. We recognize landfill depletion expense as airspace of a landfill is consumed. Our landfill depletion rates are based on the remaining disposal capacity at our landfills, considering both permitted and probable expansion airspace. We calculate the net present value of our final capping, closure and post-closure commitments by estimating the total obligation in current dollars, inflating the obligation based upon the expected date of the expenditure and discounting the inflated total to its present value using a credit-adjusted risk-free rate. Any changes in expectations that result in an upward revision to the estimated undiscounted cash flows are treated as a new liability and are inflated and discounted at rates reflecting current market conditions. Any changes in expectations that result in a downward revision (or no revision) to the estimated undiscounted cash flows result in a liability that is inflated and discounted at rates reflecting the market conditions at the time the cash flows were originally estimated. This policy results in our final capping, closure and post-closure liabilities being recorded in “layers.”  The resulting final capping, closure and post-closure obligations are recorded on the consolidated balance sheet along with an offsetting addition to site costs, which is amortized to depletion expense as the remaining landfill airspace is consumed. Interest is accreted on the recorded liability using the corresponding discount rate. The accounting methods discussed below require us to make certain estimates and assumptions. Changes to these estimates and assumptions, including as a result of inflation, could have a material effect on our financial condition and results of operations. Any changes to our estimates are applied prospectively.

Landfill development costs. Landfill development costs include the costs of acquisition, construction associated with excavation, liners, site berms, groundwater monitoring wells, gas recovery systems and leachate collection systems. We estimate the total costs associated with developing each landfill site to its final capacity. Total landfill costs include the development costs associated with expansion airspace. Expansion airspace is described below. Landfill development costs depend on future events and thus actual costs could vary significantly from our estimates. Material differences between estimated and actual development costs may affect our cash flows by increasing our capital expenditures and thus affect our results of operations by increasing our landfill depletion expense.

Final capping, closure and post-closure obligations. We accrue for estimated final capping, closure and post-closure maintenance obligations at the landfills we own, and the landfills that we operate, but do not own, under life-of-site agreements. We could have additional material financial obligations relating to final capping, closure and post-closure costs at other disposal facilities that we currently own or operate or that we may own or operate in the future. Our discount rate assumption for purposes of computing 2021 and 2020 “layers” for final capping, closure and post-closure obligations was 3.25% and 4.75%, which reflects our long-term credit adjusted risk free rate as of the end of 2020 and 2019. Our inflation rate assumption was 2.25% and 2.50% for the years ended December 31, 2021 and 2020, respectively. Significant reductions in our estimates of the remaining lives of our landfills or significant increases in our estimates of the landfill final capping, closure and post-closure maintenance costs could have a material adverse effect on our financial condition and results of operations. Additionally, changes in regulatory or legislative requirements could increase our costs related to our landfills, resulting in a material adverse effect on our financial condition and results of operations.

Disposal capacity. Our internal and third-party engineers perform surveys at least annually to estimate the remaining disposal capacity at our landfills. Our landfill depletion rates are based on the remaining disposal capacity, considering both permitted and probable expansion airspace, at the landfills that we own and at landfills that we operate, but do not

53

Table of Contents

own, under life-of-site agreements. Our landfill depletion rate is based on the term of the operating agreement at our operated landfill that has capitalized expenditures. Expansion airspace consists of additional disposal capacity being pursued through means of an expansion that has not yet been permitted. Expansion airspace that meets the following criteria is included in our estimate of total landfill airspace:

We may be unsuccessful in obtaining permits for expansion disposal capacity at our landfills. In such cases, we will charge the previously capitalized development costs to expense. This will adversely affect our operating results and cash flows and could result in greater landfill depletion expense being recognized on a prospective basis.

We periodically evaluate our landfill sites for potential impairment indicators. Our judgments regarding the existence of impairment indicators are based on regulatory factors, market conditions and operational performance of our landfills. Future events could cause us to conclude that impairment indicators exist and that our landfill carrying costs are impaired. Any resulting impairment loss could have a material adverse effect on our financial condition and results of operations.

Goodwill and indefinite-lived intangible assets testing. Goodwill and indefinite-lived intangible assets are tested for impairment on at least an annual basis in the fourth quarter of the year. In addition, we evaluate our reporting units for impairment if events or circumstances change between annual tests indicating a possible impairment. Examples of such events or circumstances include, but are not limited to, the following:

● a significant adverse change in legal factors or in the business climate;

● an adverse action or assessment by a regulator;

● a more likely than not expectation that a segment or a significant portion thereof will be sold;

● the testing for recoverability of a significant asset group within a segment; or

● current period or expected future operating cash flow losses.

As part of our goodwill impairment test, we estimate the fair value of each of our reporting units using discounted cash flow analyses.  At December 31, 2019, our reporting units consisted of our five geographic solid waste operating segments and our E&P segment.  As of July 1, 2020, we combined all operations of our E&P segment into the Southern segment, based on our determination that the two operating segments met the aggregation criteria, and eliminated the E&P segment.  We compare the fair value of each reporting unit with the carrying value of the net assets assigned to the reporting unit. If the fair value of a reporting unit is greater than the carrying value of the net assets, including goodwill, assigned to the reporting unit, then no impairment results. If the fair value is less than its carrying value, an impairment charge is recorded for the amount by which the carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. In testing indefinite-lived intangible assets for impairment, we compare the estimated fair value of each indefinite-lived intangible asset to its carrying value. If the fair value of the indefinite-lived intangible asset is less than its carrying value, an impairment charge would be recorded to earnings in our Consolidated Statements of Net Income.

Discounted cash flow analyses require significant assumptions and estimates about the future operations of each reporting unit and the future discrete cash flows related to each indefinite-lived intangible asset. Significant judgments inherent in these analyses include the determination of appropriate discount rates, the amount and timing of expected future cash flows, growth rates and income tax rates. In assessing the reasonableness of our determined fair values of our reporting units, we evaluate our results against our current market capitalization. For our impairment testing of our operating segments for the year ended December 31, 2021, we determined that the indicated fair value of our reporting units

54

Table of Contents

exceeded their carrying value by approximately 200% on average and, therefore, we did not record an impairment charge. The detailed results of our 2021, 2020 and 2019 impairment tests are described in Note 3 of our consolidated financial statements included in Item 8 of this Annual Report on Form 10-K.

Business Combination Accounting. We recognize, separately from goodwill, the identifiable assets acquired and liabilities assumed at their estimated acquisition date fair values. We measure and recognize goodwill as of the acquisition date as the excess of: (a) the aggregate of the fair value of consideration transferred, the fair value of the noncontrolling interest in the acquiree (if any) and the acquisition date fair value of our previously held equity interest in the acquiree (if any), over (b) the fair value of net assets acquired and liabilities assumed. At the acquisition date, we measure the fair values of all assets acquired and liabilities assumed that arise from contractual contingencies. We measure the fair values of all noncontractual contingencies if, as of the acquisition date, it is more likely than not that the contingency will give rise to an asset or liability.

General

Our revenues consist mainly of fees we charge customers for collection, transfer, recycling and disposal of non-hazardous solid waste and treatment, recovery and disposal of non-hazardous E&P waste.

Our solid waste collection business involves the collection of waste from residential, commercial and industrial customers for transport to transfer stations, or directly to landfills or recycling centers. Solid waste collection services include both recurring and temporary customer relationships. The services are performed under service agreements, municipal contracts or franchise agreements with governmental entities. Our existing franchise agreements and most of our existing municipal contracts give us the exclusive right to provide specified waste services in the specified territory during the contract term. These exclusive arrangements are awarded, at least initially, on a competitive bid basis and subsequently on a bid or negotiated basis. The standard customer service agreements generally range from one to three years in duration, although some exclusive franchises are for significantly longer periods. Residential collection services are also provided on a subscription basis with individual households.

The fees received for collection services are based primarily on the market, collection frequency and level of service, route density, type and volume, or weight of the waste collected, type of equipment and containers furnished, the distance to the disposal or processing facility, the cost of disposal or processing, and prices charged by competitors for similar services.

The terms of our contracts sometimes limit our ability to pass on price increases. Long-term solid waste collection contracts often contain a formula, generally based on a published price index, that automatically adjusts fees to cover increases in some, but not all, operating costs, or that limit increases to less than 100% of the increase in the applicable price index.

Revenue at landfills is primarily generated by charging tipping fees on a per ton and/or per yard basis to third parties based on the volume disposed and the nature of the waste.

Revenue at transfer stations is primarily generated by charging tipping or disposal fees on a per ton and/or per yard basis. The fees charged to third parties are based primarily on the market, type and volume or weight of the waste accepted, the distance to the disposal facility and the cost of disposal.

Many of our landfill and transfer station customers have entered into one to ten year disposal contracts with us, most of which provide for annual indexed price increases.

Our revenues from E&P waste services are primarily generated through the treatment, recovery and disposal of non-hazardous exploration and production waste from vertical and horizontal drilling, hydraulic fracturing, production and clean-up activity, as well as other services.

Our revenues from recycling services result from the sale of recycled commodities, which are generated by offering residential, commercial, industrial and municipal customers recycling services for a variety of recyclable materials,

55

Table of Contents

including compost, cardboard, mixed paper, plastic containers, glass bottles and ferrous and aluminum metals. We own and operate recycling operations and market collected recyclable materials to third parties for processing before resale. In some instances, we utilize a third party to market recycled materials.  In certain instances, we issue recycling rebates to municipal or commercial customers, which can be based on the price we receive upon the sale of recycled commodities, a fixed contractual rate or other measures. We also receive rebates when we dispose of recycled commodities at third-party facilities.

Other revenues consist primarily of the sale of methane gas and renewable energy credits generated from our MSW landfills and revenues from intermodal services. Intermodal revenue is primarily generated through providing intermodal services for the rail haul movement of cargo and solid waste containers in the Pacific Northwest through a network of intermodal facilities. The fees received for intermodal services are based on negotiated rates and vary depending on volume commitments by the shipper and destination.

No single contract or customer accounted for more than 10% of our total revenues at the consolidated or reportable segment level during the periods presented. The following table disaggregates our revenue by service line for the periods indicated (dollars in thousands of U.S. dollars).

​

Cost of operations includes labor and benefits, tipping fees paid to third-party disposal facilities, vehicle and equipment maintenance, workers’ compensation, vehicle and equipment insurance, insurance and employee group health claims expense, third-party transportation expense, fuel, the cost of materials we purchase for recycling, district and state taxes and host community fees and royalties. Our significant costs of operations in 2021 were labor, employee benefits, third-party disposal and transportation, vehicle, equipment and property maintenance, taxes and fees, insurance and fuel. We use a number of programs to reduce overall cost of operations, including increasing the use of automated routes to reduce labor and workers’ compensation exposure, utilizing comprehensive maintenance and health and safety programs, and increasing the use of transfer stations to further enhance internalization rates. We carry insurance for automobile liability, general liability, employer’s liability, environmental liability, cyber liability, employment practices liability and directors’ and officers’ liability as well as for employee group health claims, property and workers’ compensation. If we experience insurance claims or costs above or below our historically evaluated levels, our estimates could be materially affected.

Selling, general and administrative, or SG&A, expense includes management, sales force, clerical and administrative employee compensation and benefits, legal, accounting and other professional services, acquisition expenses, bad debt expense and lease cost for our administrative offices.

Depreciation expense includes depreciation of equipment and fixed assets over their estimated useful lives using the straight-line method. Depletion expense includes depletion of landfill site costs and total future development costs as remaining airspace of the landfill is consumed. Remaining airspace at our landfills includes both permitted and probable expansion airspace. Amortization expense includes the amortization of finite-lived intangible assets, consisting primarily of long-term franchise agreements and contracts, customer lists and non-competition agreements.  We use an accelerated or straight line basis for amortization, depending on the attributes of the related intangibles.  Goodwill and indefinite-lived

56

Table of Contents

intangible assets, consisting primarily of certain perpetual rights to provide solid waste collection and transportation services in specified territories, are not amortized.

We capitalize some third-party expenditures related to development projects, such as legal and engineering. We expense all third-party and indirect acquisition costs, including third-party legal and engineering expenses, executive and corporate overhead, public relations and other corporate services, as we incur them. We charge against net income any unamortized capitalized expenditures and advances (net of any portion that we believe we may recover, through sale or otherwise) that may become impaired, such as those that relate to any operation that is permanently shut down and any landfill development project that we believe will not be completed. We routinely evaluate all capitalized costs, and expense those related to projects that we believe are not likely to succeed. For example, if we are unsuccessful in our attempts to obtain or defend permits that we are seeking or have been awarded to operate or expand a landfill, we will no longer generate anticipated income from the landfill and we will be required to expense in a future period up to the carrying value of the landfill or expansion project, less the recoverable value of the property and other amounts recovered.

Presentation of Results of Operations, Segment Reporting, and Liquidity and Capital Resources

The following discussion and analysis of our Results of Operations, Segment Reporting, and Liquidity and Capital Resources includes a comparison for the year ended December 31, 2021 to the year ended December 31, 2020. A similar discussion and analysis that compares the year ended December 31, 2020 to the year ended December 31, 2019 can be found in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the year ended December 31, 2020.

Operations that were divested in 2021, and the full year impact of operations that were divested in 2020, decreased revenues by approximately $12.6 million for the year ended December 31, 2021.

During the year ended December 31, 2021, the net increase in prices charged to our customers at our existing operations was $257.2 million, consisting of $243.5 million of core price increases and surcharges of $13.7 million.

During the year ended December 31, 2021, volume increases in our existing business increased solid waste revenues by $85.0 million as many of our markets benefitted from increased business activity resulting from reductions in COVID-19-related restrictions.

E&P waste revenues at facilities owned during the years ended December 31, 2021 and 2020 decreased $18.9 million attributable to the first and second quarter results in 2021 (which had a combined decrease of $39.0 million) being adversely impacted by decreases in the demand for crude oil as a result of economic disruptions from the COVID-19 pandemic resulting in a drop in the value of crude oil, decreases in drilling and production activity levels and decreases in overall demand for our E&P waste services, with our third and fourth quarter results in 2021 (which had a combined increase of $20.1 million) benefitting from recoveries in the demand for crude oil and our E&P waste services.

An increase in the average Canadian dollar to U.S. dollar currency exchange rate resulted in an increase in revenues of $48.1 million for the year ended December 31, 2021. The average Canadian dollar to U.S. dollar exchange rates on our Canadian revenues were 0.7982 and 0.7472 for the years ended December 31, 2021 and 2020, respectively.

Revenues from sales of recyclable commodities at facilities owned during the years ended December 31, 2021 and 2020 increased $92.7 million due primarily to higher prices for old corrugated cardboard, aluminum, plastics and other paper products, higher volumes collected from residential recycling customers and the partial recovery of collected commercial recycling volumes which declined in the prior year period due to economic disruptions resulting from the COVID-19 pandemic.  

Other revenues increased $25.9 million during the year ended December 31, 2021, due primarily to a $24.4 million increase resulting from higher prices for renewable energy credits associated with the generation of landfill gas at our Canada segment, a $5.4 million increase in landfill gas sales at our U.S. segments and a $1.9 million increase in other non-core revenue sources, partially offset by a $5.8 million decrease in intermodal revenues due primarily to customer losses and shipping port logistical constraints resulting in a reduction in intermodal cargo volumes.

Cost of Operations.  Total cost of operations increased $377.3 million, or 11.5%, to $3.654 billion for the year ended December 31, 2021, from $3.277 billion for the year ended December 31, 2020. The increase was primarily the result of an increase in operating costs at our existing operations of $235.3 million, assuming foreign currency parity, $123.6 million of additional operating costs from acquisitions closed during, or subsequent to, the year ended December 31, 2020 and $26.5 million resulting from an increase in the average foreign currency exchange rate in effect during the comparable reporting periods, partially offset by a decrease in operating costs of $8.1 million at operations divested during or subsequent to the year ended December 31, 2020.

The increase in operating costs of $235.3 million, assuming foreign currency parity, at our existing operations for the year ended December 31, 2021, consisted of an increase in labor expenses at our solid waste operations of $80.6 million due primarily to employee pay increases and headcount additions to support solid waste volume increases, an increase in truck, container, equipment and facility maintenance and repair expenses of $35.8 million due primarily to increased collection routes and equipment operating hours and parts and service rate increases, an increase in diesel fuel expense of $29.7 million due to higher fuel prices, an increase in third-party disposal expenses of $28.7 million due primarily to increased solid waste collection volumes, an increase in third-party trucking and transportation expenses of $27.7 million due primarily to increased transfer station and landfill special waste volumes requiring trucking and transportation services to our landfills, an increase in taxes on revenues of $16.8 million due primarily to increased revenues in our solid waste markets, an increase in employee medical benefits expenses of $13.2 million due to an increase in medical visits, an increase in subcontracted hauling services at our solid waste operations of $10.8 million due to outsourcing the servicing of certain non-strategic contracts and commercial collection customers to third party haulers, an increase in 401(k) matching expenses of $10.8 million due to the prior year period reflecting less expenses as we suspended our 401(k) match

During the year ended December 31, 2020, we concluded that a triggering event occurred which required us to perform an impairment test of the property and equipment and intangible assets of our E&P waste operations as of June 30, 2020. As a result of the impairment test, we concluded that the carrying value of four E&P landfills exceeded their estimated fair value, resulting in an impairment charge of $417.4 million to property and equipment. The remaining net losses of $49.3 million recorded during the year ended December 31, 2020 consisted of $18.4 million to adjust the carrying value of contingent consideration liabilities, $13.3 million of charges to adjust the carrying values of certain long-lived assets acquired in the Progressive Waste acquisition, $6.9 million of losses on property and equipment that were disposed of through sales or as a result of being damaged in operations, $6.1 million of charges to terminate or write off the carrying cost of certain contracts that were not, or are not expected to be, renewed prior to their original estimated termination date, $3.6 million of losses on the disposal of certain non-strategic operating locations and $1.0 million of other net charges.

Our operating results for the year ended December 31, 2020 were adversely impacted by the aforementioned impairment charge at our E&P waste operations of $417.4 million. The remaining increase in our operating income for the year ended December 31, 2021 was due primarily to price increases for our solid waste services, increases in solid waste collection and disposal volumes, operating income contributions from increased sales of recyclable commodities and renewable energy credits associated with the generation of landfill gas, operating income generated from acquisitions closed during, or subsequent to, the year ended December 31, 2020 and an increase in the average Canadian dollar to U.S. dollar currency exchange rate.

Operating income as a percentage of revenues increased 9.3 percentage points to 16.9% for the year ended December 31, 2021, from 7.6% for the year ended December 31, 2020.  The increase as a percentage of revenues was comprised of an 8.0 percentage point decrease in impairments and other operating items, a 0.8 percentage point decrease in cost of operations, a 0.5 percentage point decrease in depreciation expense and a 0.1 percentage point decrease in amortization expense, partially offset by at 0.1 percentage point increase in SG&A expense.

The increase was primarily attributable to an increase of $11.2 million from the September 2021 issuance of our 2032 Senior Notes (as defined below) and our 2052 Senior Notes (as defined below), an increase of $4.3 million from higher net interest rates on borrowings outstanding under our Credit Agreement due primarily to $600 million in interest rate swap agreements commencing in October 2020 at higher interest rates than $575 million in interest rate swap agreements which expired between September 2020 and October 2020, an increase of $4.0 million from the full year impact of the January 2020 issuance of our 2030 Senior Notes (as defined below) and the March 2020 issuance of our 2050 Senior Notes (as defined below) and an increase of $0.5 million due to an increase in the average borrowings outstanding under our Credit Agreement, partially offset by a decrease of $18.9 million from the repayment of $1.75 billion of senior unsecured notes in 2021 and $0.7 million of other net decreases.

Interest Income.  Interest income decreased $2.4 million to $2.9 million for the year ended December 31, 2021, from $5.3 million for the year ended December 31, 2020. The decrease was primarily attributable to lower reinvestment rates and lower average cash balances in the current period.

Other Income (Expense), Net.  Other income (expense), net increased $7.7 million, to an income total of $6.3 million for the year ended December 31, 2021, from an expense total of $1.4 million for the year ended December 31, 2020.

Loss on Early Extinguishment of Debt.  Loss on early extinguishment of debt was $115.3 million for the year ended December 31, 2021 and consists of the payment of a make-whole premium and the write-off of remaining unamortized loan fees associated with the early repayment of the outstanding senior notes under our master note purchase agreements.

Income Tax Provision.  Income taxes increased $102.4 million, to $152.3 million for the year ended December 31, 2021, from $49.9 million for the year ended December 31, 2020.  Our effective tax rate for the year ended December 31, 2021 was 19.8%. Our effective tax rate for the year ended December 31, 2020 was 19.7%. 

The income tax provision for the year ended December 31, 2021 included a benefit of $2.1 million from share-based payment awards being recognized in the income statement when settled, as well as a portion of our internal financing being taxed at effective rates substantially lower than the U.S. federal statutory rate.

The income tax provision for the year ended December 31, 2020 included a $27.4 million expense associated with certain 2019 inter-entity payments no longer being deductible for tax purposes due to the finalization of tax regulations on April 7, 2020 under Internal Revenue Code Section 267A and a $4.1 million expense related to an increase in our deferred income tax liabilities resulting from the impairment of certain assets within our E&P waste operations, which impacted the geographical apportionment of our state income taxes.  Additionally, the income tax benefit for the year ended December 31, 2020 included a benefit of $5.4 million from share-based payment awards being recognized in the income statement when settled.

Our effective tax rate is dependent upon the proportion of pre-tax income among the jurisdictions where we do business. As such, our effective tax rate will be subject to some variability depending upon the proportional contribution of pre-tax income across jurisdictions in any period.

Segment Reporting

We manage our operations through the following five geographic solid waste operating segments: Eastern, Southern, Western, Central and Canada. Our five geographic solid waste operating segments comprise our reportable segments.  Our Chief Operating Decision Maker evaluates operating segment profitability and determines resource allocations based on several factors, of which the primary financial measure is segment EBITDA. We define segment EBITDA as earnings before interest, taxes, depreciation, amortization, impairments and other operating items, other income (expense) and loss on early extinguishment of debt. Segment EBITDA is not a measure of operating income, operating performance or liquidity under GAAP and may not be comparable to similarly titled measures reported by other companies. Our management uses segment EBITDA in the evaluation of segment operating performance as it is a profit measure that is

generally within the control of the operating segments.  Each operating segment is responsible for managing several vertically integrated operations, which are comprised of districts.

Summarized financial information for our reportable segments are shown in the following table in thousands of U.S. dollars and as a percentage of total segment revenue for the periods indicated:

A reconciliation of segment EBITDA to Income before income tax provision is included in Note 17 to the consolidated financial statements included in Item 8 of this Annual Report on Form 10-K.

Significant changes in revenue, EBITDA and depreciation, depletion and amortization for our reportable segments for the year ended December 31, 2021, compared to the year ended December 31, 2020, are discussed below.

Eastern

Revenue increased $185.4 million to $1.521 billion for 2021, from $1.336 billion for 2020, due to price increases, solid waste collection and disposal volume increases in the third and fourth quarters of 2021, contributions from acquisitions, higher prices for recyclable commodities and higher volumes collected from commercial recycling customers, partially offset by solid waste volume decreases occurring in the first two quarters of 2021 attributable primarily to COVID-19-related economic disruptions in our Northeastern markets.

EBITDA increased $61.1 million to $404.5 million, or a 26.6% EBITDA margin for 2021, from $343.4 million, or a 25.7% EBITDA margin for 2020. The increase in our EBITDA margin was due to price-led increases in revenue at locations owned in the comparable periods, a decrease in expenses for uncollectible accounts receivable and a decrease in supplemental bonuses and other cash incentive compensation to non-management personnel, partially offset by increased diesel fuel expenses, increased medical benefits expenses and increased 401(k) matching expenses.

63

Table of Contents

Depreciation, depletion and amortization for 2021 increased $16.2 million, to $239.1 million for 2021, from $222.9 million for 2020, due to assets acquired in acquisitions, higher depreciation from additions to our fleet and equipment and higher depletion from increased landfill volumes.

Southern

Revenue increased $77.1 million to $1.447 billion for 2021, from $1.370 billion for 2020, due to increased solid waste collection and disposal volumes, solid waste price increases, contributions from acquisitions and higher prices for recyclable commodities, partially offset by reduced E&P waste revenues attributable to decreases in drilling and production activity levels resulting in decreases in the demand for our E&P waste services and a decrease resulting from the divestiture of certain non-strategic operating locations.

EBITDA increased $25.6 million to $395.0 million, or a 27.3% EBITDA margin for 2021, from $369.4 million, or a 27.0% EBITDA margin for 2020. The increase in our EBITDA margin was due to price-led increases in solid waste revenue at locations owned in the comparable periods, a decrease in expenses for auto and workers’ compensation claims, a decrease in expenses for uncollectible accounts receivable and a decrease in supplemental bonuses and other cash incentive compensation to non-management personnel, partially offset by an increase in subcontracted hauling services at our solid waste operations, increased diesel fuel expenses, increased medical benefits expenses, increased legal expenses and increased 401(k) matching expenses.

Depreciation, depletion and amortization for 2021 decreased $0.7 million, to $189.0 million for 2021, from $189.7 million for 2020, due to a decrease from the divestiture of certain non-strategic operating locations and our E&P locations recognizing lower depreciation as a result of reductions in operating equipment and lower depletion due to reductions in customer disposal volumes, partially offset by higher depreciation from additions to fleet and equipment at our solid waste operations and higher depletion from increased solid waste landfill volumes.

Western

Revenue increased $130.4 million to $1.280 billion for 2021, from $1.150 billion for 2020, due to increased collection and disposal volumes, price increases, contributions from acquisitions, higher prices for recyclable commodities and higher volumes collected from residential recycling customers, partially offset by reduced intermodal revenue.

EBITDA increased $41.0 million to $405.8 million, or a 31.7% EBITDA margin for 2021, from $364.8 million, or a 31.7% EBITDA margin for 2020. Our EBITDA margin was unchanged due the favorable impacts of the increase in revenue at locations owned in the comparable periods resulting from the economic recovery, a decrease in expenses for processing recyclable commodities and a decrease in supplemental bonuses and other cash incentive compensation to non-management personnel being offset by the impact of acquisitions closed during, or subsequent to, the year ended December 31, 2020 having lower EBITDA margins than our segment average, increased diesel fuel expenses, increased medical benefits expenses and increased 401(k) matching expenses.

Depreciation, depletion and amortization for 2021 increased $14.8 million, to $130.0 million for 2021, from $115.2 million for 2020, due to assets acquired in acquisitions, higher depreciation from additions to our fleet and equipment and higher depletion from increased landfill volumes.

Central

Revenue increased $166.1 million to $1.046 billion for 2021, from $880.3 million for 2020, due to increased collection and disposal volumes, price increases, contributions from acquisitions and higher prices for recyclable commodities.

EBITDA increased $46.4 million to $359.4 million, or a 34.3% EBITDA margin for 2021, from $313.0 million, or a 35.6% EBITDA margin for 2020. The decrease in our EBITDA margin was due to the impact of acquisitions closed during, or subsequent to, the year ended December 31, 2020 having lower EBITDA margins than our segment average, increased labor expenses attributable to pay rate increases, increased vehicle and equipment maintenance and repair

expenses, increased medical benefits expenses, increased 401(k) matching expenses and increased expenses for uncollectible accounts receivable.

Depreciation, depletion and amortization for 2021 increased $21.1 million, to $134.1 million for 2021, from $113.0 million for 2020, due to assets acquired in acquisitions, higher depreciation from additions to our fleet and equipment and higher depletion from increased landfill volumes.

Canada

Revenue increased $146.2 million to $856.7 million for 2021, from $710.5 million for 2020, due to price increases, increased collection and disposal volumes, a higher average foreign currency exchange rate in effect during the comparable reporting periods, higher prices for renewable energy credits associated with the generation of landfill gas, higher prices for recyclable commodities and higher volumes collected from commercial recycling customers.

EBITDA increased $83.8 million to $339.9 million, or a 39.7% EBITDA margin for 2021, from $256.1 million, or a 36.0% EBITDA margin for 2020. The increase in our EBITDA margin was due to price-led increases in revenue at locations owned in the comparable periods, a decrease in expenses for uncollectible accounts receivable and a decrease in supplemental bonuses and other cash incentive compensation to non-management personnel, partially offset by increased diesel fuel expenses and increased cost of recyclable commodities expenses.

Depreciation, depletion and amortization for 2021 increased $8.2 million, to $111.5 million for 2021, from $103.3 million for 2020, due to a higher average foreign currency exchange rate, higher depreciation from additions to our fleet and equipment and higher depletion from increased landfill volumes, partially offset by lower amortization expense attributable to intangible assets becoming fully amortized during the current reporting period.

Corporate

EBITDA decreased $4.3 million, to a loss of $19.6 million for 2021, from a loss of $15.3 million for 2020. The decrease was due to increased equity-based compensation expenses, increased travel, meeting, training and community activity expenses, increased direct acquisition expenses, increased legal expenses, increased employee payroll and relocation expenses and increased deferred compensation expenses, partially offset by increased allocations of corporate overhead expenses to our segments.

Operating Activities Cash Flows

For the year ended December 31, 2021, net cash provided by operating activities was $1.698 billion. For the year ended December 31, 2020, net cash provided by operating activities was $1.409 billion. The $289.7 million increase was due primarily to the following:

As of December 31, 2021, we had a working capital deficit of $200.0 million, including cash and equivalents of $147.4 million.  Our working capital decreased $579.6 million from a working capital surplus of $379.6 million at December 31, 2020 including cash and equivalents of $617.3 million, due primarily to the impact of decreased cash balances, increased deferred revenue and increased current portion of contingent consideration being partially offset by increased accounts receivable. To date, we have experienced no loss or lack of access to our cash and equivalents; however,

Table of Contents

we can provide no assurances that access to our cash and equivalents will not be impacted by adverse conditions in the financial markets.  Our strategy in managing our working capital is generally to apply the cash generated from our operations that remains after satisfying our working capital and capital expenditure requirements, along with share repurchase and dividend programs, to reduce the unhedged portion of our indebtedness under our Credit Agreement and to minimize our cash balances.

Investing Activities Cash Flows

Net cash used in investing activities increased $647.4 million to $1.693 billion for the year ended December 31, 2021, from $1.046 billion for the year ended December 31, 2020. The significant components of the increase included the following:

Financing Activities Cash Flows

Net cash used in financing activities increased $421.3 million to $499.5 million for the year ended December 31, 2021, from $78.2 million for the year ended December 31, 2020. The significant components of the increase included the following:

Our business is capital intensive. Our capital requirements include acquisitions and capital expenditures for landfill cell construction, landfill development, landfill closure activities and intermodal facility construction in the future.

On July 27, 2021, our Board of Directors approved, subject to receipt of regulatory approvals, the annual renewal of our normal course issuer bid, or the NCIB, to purchase up to 13,025,895 of our common shares during the period of August 10, 2021 to August 9, 2022 or until such earlier time as the NCIB is completed or terminated at our option. Shareholders may obtain a copy of our TSX Form 12 – Notice of Intention to Make a Normal Course Issuer Bid, without charge, by request directed to our Executive Vice President and Chief Financial Officer at (832) 442-2200.  The timing and amounts of any repurchases pursuant to the NCIB will depend on many factors, including our capital structure, the market price of our common shares and overall market conditions. All common shares purchased under the NCIB will be immediately cancelled following their repurchase. Information regarding our NCIB plan can be found under the section

Normal Course Issuer Bid in Note 14, “Shareholders’ Equity,”  of our consolidated financial statements included in Item 8 of this Annual Report on Form 10-K and is incorporated herein by reference.

The Board of Directors of the Company authorized the initiation of a quarterly cash dividend in October 2010 and has increased it on an annual basis. In October 2021, our Board of Directors authorized an increase to our regular quarterly cash dividend of $0.025, from $0.205 to $0.230 per share. Cash dividends of $220.2 million and $199.9 million were paid during the years ended December 31, 2021 and 2020, respectively. We cannot assure you as to the amounts or timing of future dividends.

We made $744.3 million in capital expenditures for property and equipment during the year ended December 31, 2021, and we expect to make total capital expenditures for property and equipment of approximately $850 million in 2022.  We intend to fund our planned 2022 capital expenditures principally through cash on hand, internally generated funds and borrowings under our Credit Agreement. In addition, we may make substantial additional capital expenditures in acquiring land and solid waste businesses. If we acquire additional landfill disposal facilities, we may also have to make significant expenditures to bring them into compliance with applicable regulatory requirements, obtain permits or expand our available disposal capacity. We cannot currently determine the amount of these expenditures because they will depend on the number, nature, condition and permitted status of any acquired landfill disposal facilities. We believe that our cash and equivalents, Credit Agreement and the funds we expect to generate from operations will provide adequate cash to fund our working capital and other cash needs for the foreseeable future. However, disruptions in the capital and credit markets could adversely affect our ability to draw on our Credit Agreement or raise other capital. Our access to funds under the Credit Agreement is dependent on the ability of the banks that are parties to the agreement to meet their funding commitments. Those banks may not be able to meet their funding commitments if they experience shortages of capital and liquidity or if they experience excessive volumes of borrowing requests within a short period of time.

We have a revolving credit and term loan agreement (as amended, restated, amended and restated, supplemented or otherwise modified from time to time, the “Credit Agreement”) with Bank of America, N.A., acting through its Canada Branch, as the global agent, the swing line lender and a letter of credit issuer, Bank of America, N.A., as the U.S. Agent and a letter of credit issuer, the other lenders named therein (the “Lenders”) and any other financial institutions from time to time party thereto. There are no subsidiary guarantors under the Credit Agreement. The Credit Agreement has a scheduled maturity date of July 30, 2026, which may be extended further upon agreement by Lenders holding at least 50% of the commitments and credit extensions outstanding, with respect to their respective commitments and credit extensions outstanding.  Any Lender that does not agree to an extension of the maturity date shall not be so extended with respect to their commitments and credit extensions.

As of December 31, 2021, $650.0 million under the term loan and $803.9 million under the revolving credit facility were outstanding under the Credit Agreement, exclusive of outstanding standby letters of credit of $112.3 million. We also had $13.5 million of letters of credit issued and outstanding at December 31, 2021 under facilities other than the Credit Agreement.  We did not have any amounts outstanding under our master note purchase agreements.

Pursuant to the terms and conditions of a Master Note Purchase Agreement dated as of June 1, 2016 (as amended, restated, amended and restated, supplemented or otherwise modified from time to time, the “2016 NPA”) between us and certain accredited institutional investors, we issued senior unsecured notes (the “2016 Private Placement Notes”) consisting of (i) $150.0 million of senior notes due June 1, 2021 (the “June 2021 Private Placement Notes”), (ii) $200.0 million of senior notes due June 1, 2023, (iii) $150.0 million of senior notes due April 20, 2024, (iv) $400.0 million of senior notes due June 1, 2026 and (v) $250.0 million of senior notes due April 20, 2027.

Pursuant to the terms and conditions of a Master Note Purchase Agreement dated as of July 15, 2008 (as amended, restated, amended and restated, assumed, supplemented or otherwise modified from time to time, the “2008 NPA”) between us and certain accredited institutional investors, we issued senior unsecured notes (the “2008 Private Placement Notes” and together with the 2016 Private Placement Notes, the “Private Placement Notes”) consisting of (i) $100.0 million of senior notes due April 1, 2021 (the “April 2021 Private Placement Notes” and together with the June 2021 Private Placement Notes, the “2021 Private Placement Notes”), (ii) $125.0 million of senior notes due August 20, 2022 and (iii) $375.0 million of senior notes due August 20, 2025.

The following assumptions were made in calculating cash interest payments:

Contingent consideration payments include $94.3 million recorded as liabilities in our consolidated financial statements at December 31, 2021, and $18.5 million of future interest accretion on the recorded obligations.

We are party to operating lease agreements and finance leases as discussed in Note 7 to the consolidated financial statements included in Item 8 of this Annual Report on Form 10-K. These lease agreements are established in the ordinary course of our business and are designed to provide us with access to facilities and equipment at competitive, market-driven prices.

The estimated final capping, closure and post-closure expenditures presented above are in current dollars.

​

We have obtained standby letters of credit as discussed in Note 11 to the consolidated financial statements included in Item 8 of this Annual Report on Form 10-K and financial surety bonds as discussed in Note 13 to the consolidated financial statements included in Item 8 of this Annual Report on Form 10-K. These standby letters of credit and financial surety bonds are generally obtained to support our financial assurance needs and landfill and E&P waste operations. These arrangements have not materially affected our financial position, results of operations or liquidity during the year ended December 31, 2021, nor are they expected to have a material impact on our future financial position, results of operations or liquidity.

From time to time, we evaluate our existing operations and their strategic importance to us. If we determine that a given operating unit does not have future strategic importance, we may sell or otherwise dispose of those operations. Although we believe our reporting units would not be impaired by such dispositions, we could incur losses on them.

Non-GAAP Financial Measures

Adjusted Free Cash Flow

We present adjusted free cash flow, a non-GAAP financial measure, supplementally because it is widely used by investors as a valuation and liquidity measure in the solid waste industry. Management uses adjusted free cash flow as one of the principal measures to evaluate and monitor the ongoing financial performance of our operations. We define adjusted free cash flow as net cash provided by operating activities, plus or minus change in book overdraft, plus proceeds from disposal of assets, less capital expenditures for property and equipment and distributions to noncontrolling interests. We further adjust this calculation to exclude the effects of items management believes impact the ability to assess the operating performance of our business. This measure is not a substitute for, and should be used in conjunction with, GAAP liquidity or financial measures. Other companies may calculate adjusted free cash flow differently. Our adjusted free cash flow for the years ended December 31, 2021, 2020 and 2019, are calculated as follows (amounts in thousands of U.S. dollars):
