PART I

ITEM 1.BUSINESS

Overview

Republic Services is one of the largest providers of environmental services in North America, as measured by revenue. We operate across the United States and Canada through 377 collection operations, 255 transfer stations, 79 recycling centers, 207 active landfills, 2 treatment, recovery and disposal facilities, 24 treatment, storage and disposal facilities (TSDF), 5 salt water disposal wells, 15 deep injection wells, 9 industrial wastewater treatment facilities, and 2 polymer centers. We are engaged in 84 landfill gas-to-energy and other renewable energy projects and had post-closure responsibility for 124 closed landfills.

We believe the total addressable United States and Canada environmental services market in which we operate generates approximately $163 billion of annual revenue, which includes the $110 billion recycling and waste industry, $37 billion of the broader environmental solutions industry, and $16 billion in sustainability innovation (described below) and emerging waste and recycling technologies. Within our recycling and waste business, we prioritize investments in market verticals with above-average growth rates and higher return profiles. The environmental solutions market remains fragmented, which provides consolidation opportunities to drive scale. In our sustainability innovation businesses, we believe customer demand for products and services that respond to evolving environmental trends, including circularity and decarbonization, should support above average growth rates and attractive returns. We believe we can further expand our addressable market into other segments of the environmental services industry over time by leveraging our differentiated capabilities, including (1) customer zeal, (2) digital and (3) sustainability.

We operate throughout the United States and Canada, but the physical collection and recycling or disposal of material is largely a local business, and the dynamics and opportunities differ in each market we serve. By combining local operating management with standardized business practices, we drive greater overall operating efficiency across the Company while maintaining day-to-day operating decisions at the local level, closest to the customer.

Our purpose-driven vision is to partner with customers to create a more sustainable world. We believe that our products and services are valuable to our customers and essential for long-term sustainability.

We further believe our focus on and commitment to sustainability allows us to attract and retain the best talent, win more customers, increase customer loyalty and, ultimately, drive higher revenue and profits.

Foundational Elements

Our strategy is designed to generate profitable growth by sustainably managing our customers’ needs, and it is underpinned by three foundational elements – (1) our market position, (2) our operating model and (3) our people and talent focus.

Market Position

Our goal is to develop the best vertically integrated market position to enable us to build density and improve returns. We strive to have a leading market position in each of the markets we serve, or have a clear path toward how we will achieve a leading market position over time. In situations where we cannot establish a leading market position, or where operations are not generating acceptable returns, we may decide to divest certain assets and reallocate resources to other markets.

We have a robust market planning process to identify opportunities to grow internally through capital investments and infrastructure development and externally through acquisitions and public-private partnerships. Additionally, our market planning process allows us to analyze market conditions and proactively adjust to trends as they emerge, including the effects of legislation, demographic shifts and changes in the market and the competitive landscape.

Internal Growth

Several key drivers of internal growth are discussed below:

•Volume Growth - Volume growth through increases in our customer base and service offerings is the most capital efficient method to grow our business. We believe volumes are driven by population growth, household formation and new business formation. We seek to obtain long-term contracts for collecting recyclables, solid waste and industrial waste under residential collection contracts with municipalities, exclusive franchise agreements, small-container and large-container contracts and environmental solutions service contracts. We also look to enter into long-term recycling and disposal contracts with municipalities and other third parties. By obtaining such long-term agreements, we can grow our contracted revenue base at a rate consistent with the underlying economic growth in these markets. In

TableofContents

addition, by securing long-term agreements, we are better able to help ensure we earn an appropriate return on the capital deployed.

•Price Increases - We seek to secure price increases necessary to offset increased costs, improve our operating margins and earn an appropriate return on our substantial investments in vehicles, equipment, transfer stations, recycling centers, TSDFs, deep well injection facilities, landfills, and other post-collection infrastructure.

•Expansion of Recycling Capabilities-Based on the most recent United States Environmental Protection Agency (EPA) data, approximately 32% of municipal solid waste is recycled and/or composted. We expect that percentage to increase over the long-term as communities enhance and expand their recycling programs for their residents. As a key player in the circular economy, we are strategically focused on expanding recycling volume through innovative material handling processes and programs to help our customers achieve their goals related to sustainability and environmentally sound practices while also generating an appropriate return. In 2024, we commenced operations at our first Polymer Center in Las Vegas, Nevada. In 2025, we commenced operations at our second Polymer Center in Indianapolis, Indiana and construction began at our third Polymer Center in Allentown, Pennsylvania. Our Polymer Centers are part of a vertical integration that will advance circularity for plastics and help us manage the plastics stream from curbside collection to delivery of recycled content for consumer packaging. We believe our Polymer Centers will enable us to produce food-grade drop-in substitutes for virgin plastics, while allowing us to expand plastics circularity across North America. In 2023, we announced the development of Blue Polymers, a joint-venture with Ravago JV Holdings, LLC, creating vertical integration that will further advance circularity by acquiring all olefins produced by the Polymer Centers to further process and manufacture custom blended pellets for food-grade and non-food-grade packaging. In 2025, operations commenced at the first Blue Polymers facility in Indianapolis, Indiana, and a second Blue Polymers facility is currently being constructed in Buckeye, Arizona. We will continue to look for opportunities to expand or enhance our recycling capabilities in markets where customers are demanding these services, demonstrating a willingness to pay and where we can earn an appropriate return on our investment.

•Infrastructure Development - We seek to identify opportunities to further our position as a vertically integrated service provider in markets where we are not fully integrated. Our goal is to create market-specific, vertically integrated operations typically consisting of one or more collection operations, transfer stations, recycling centers, TSDFs, deep well injection facilities, and landfills. Where appropriate, we seek to obtain permits to build recycling centers, transfer stations, TSDFs, deep well injection facilities, and landfills that would vertically integrate our waste services or expand the service areas for our existing disposal sites. Additionally, we seek opportunities to expand and permit new airspace at our existing landfills in order to replace airspace consumed. Development projects, while generally less capital intensive than acquisitions, typically require extensive permitting efforts that can take years to complete with no assurance of success. We undertake development projects when we believe there is a reasonable probability of success and reasonably priced acquisition opportunities are not available. Through landfill and fleet innovation, recycling and circularity of key materials and renewable energy production, we are committed to continuous development of environmentally responsible operations that increase our efficiency as well as our ability to partner with customers to create a more sustainable world.

External Growth - Acquisitions and Public-Private Partnerships

•Our acquisition growth strategy focuses primarily on acquiring privately held environmental services businesses that complement our existing business platform. We believe our ability to successfully complete these acquisitions is enhanced by the challenges facing many privately-held companies, including increasing competition in the environmental services industry, increasing capital requirements due to changes in regulatory requirements and technology and the limited number of exit strategies for privately-held companies. We also evaluate stand-alone opportunities to acquire businesses and/or facilities that are being divested by other publicly-owned companies.

We expect to continue to invest in value-enhancing acquisitions in existing markets. Given our free cash flow, availability under our credit facilities and our ability to access the public capital markets, we have the financial flexibility to make additional acquisitions that will complement our existing business platform, including larger acquisitions if the right opportunities present themselves.

We also focus on growth through public-private partnerships, which include the recycling and waste operations and facilities of municipal and other local governments. We believe over time we have an opportunity to acquire operations and facilities from municipalities and other local governments as they seek to raise capital and/or reduce risk.

We realize synergies from consolidating businesses into our existing operations, whether through acquisitions or public-private partnerships, which allows us to reduce capital expenditures and expenses associated with truck routing, personnel, fleet maintenance, inventories and back-office administration.

Operating Model

Our operating model enables us to deliver consistent, high-quality service to all our customers through the Republic Way: One Way. Everywhere. Every Day. This approach of developing standardized processes with rigorous controls and tracking allows us to leverage our scale and deliver durable operational excellence. The Republic Way is the key to harnessing the best of what we do as operators and translating that across all facets of our business. Key elements of our operating model are our organizational structure, safety, fleet automation, fleet electrification and standardized maintenance.

Organizational Structure

A key enabler of the Republic Way operating model is our organizational structure that fosters a high performance culture by maintaining 360-degree accountability and full profit and loss responsibility with local management, supported by a functional structure to provide subject matter expertise. This structure allows us to take advantage of our scale by coordinating functionally across all of our markets, while empowering local management to respond to unique market dynamics.

Through this operating model, we have rolled out several productivity and cost control initiatives designed to deliver the best service possible to our customers in an efficient and environmentally sound way.

Our senior management evaluates, oversees and manages the financial performance of our operations through three field groups, referred to as Group 1, Group 2 and Group 3. Group 1 is our recycling and waste business operating primarily in geographic areas located in the western United States. Group 2 is our recycling and waste business operating primarily in geographic areas located in the southeastern and mid-western United States, the eastern seaboard of the United States and Canada. Group 3 is our environmental solutions business operating in geographic areas located across the United States and Canada. These groups each provide integrated environmental services, including but not limited to collection, transfer, recycling and disposal.

Safety

Republic is committed to the safety of our employees, customers and the communities we serve. We have a dedicated team of safety professionals at our corporate headquarters and within our field operations, led by our Vice President of Environmental Health and Safety who reports directly to our Chief Operating Officer. Due to the nature of our industry, safety is a top priority, and we recognize and reward employees for outstanding safety records. Over the past 10 years, our safety performance (based on OSHA recordable rates) has been 23% better than the industry average. Our Think, Choose, Live motto encapsulates our everyday safety messaging to our employees to: Think about what you are doing, Choose the safe answer and Live to go home to your family. With the phrase printed on numerous items, including hard hats and the equipment our employees use, there are constant reminders for employees to go home in the same condition in which they came to work. Our goal is to ensure every one of our employees returns home safely each night.

Through our Safety Amplified program, we are providing more tools and driving greater awareness to help our teams better execute our safety standards. Regular training, multifaceted programs and strategic partnerships are key components to this program. It is simple by design and comprised of actions and activities that ensure safety is embedded in all we do. The program includes six initiatives to help us achieve our goal to have zero employee fatalities and reduce our OSHA Total Recordable Incident Rate.

•Focus Together: This effort is the core of our safety program and is designed to help frontline employees eliminate the six most common types of serious incidents.

•Lead Together: We provide best-in-class communication channels and advanced training techniques for all frontline supervisors and managers to help them guide their teams.

•Partner Together: Staying safe requires involvement by employees at all levels. We’ve increased leadership visits with frontline employees and supervisors to support each divisions’ safety goals.

•Celebrate Together: We take pride in recognizing employees who demonstrate a relentless commitment to safety. Employees with the best driving records are eligible for the industry’s most prestigious award, the National Waste & Recycling Association’s Driver of the Year. Republic drivers have won 66% of the Driver of the Year awards issued for the large truck category since 2009. In addition, our best drivers are recognized and rewarded with competing in our National Road-EO competition.

•Analyze Together: We analyze real-time data to make short- and long-term decisions and identify opportunities for improvement. Examples include analysis of roadway awareness training, data mapping and other employee protection and preparedness insights.

•Innovate Together: We employ the latest technologies in our fleet, including driver-supported automation, rear cameras, in-cab backup alarms and event recording systems, and we take a data-driven approach to support our

employees. We also work with equipment manufacturers to incorporate safety elements such as seat belt alarms, blind spot awareness, lane departure alarms and other potentially lifesaving equipment in our fleet.

We believe our Safety Amplified program provides additional benefits for our Company and stakeholders including:

•further strengthening relationships within the communities we serve;

•enhancing customer trust;

•streamlining operational processes and increasing productivity;

•delivering a reputational advantage, including positioning our Company as an employer-of-choice;

•maintaining and sustaining a safety culture in all areas of our business; and

•contributing to employee engagement.

For more information regarding our safety performance, refer to our Sustainability Accounting Standards Board (SASB) report, which can be found at republicservices.com/sustainability. The information contained on our website shall not be deemed incorporated by reference in this Annual Report on Form 10-K or in any other filing we make under the Securities Exchange Act of 1934, as amended (Exchange Act).

Fleet Automation

Approximately 79% of our residential routes have been converted to automated single-driver trucks. By converting our residential routes to automated service, we reduce labor costs, improve driver productivity, decrease emissions and create a safer work environment for our employees. Additionally, communities using automated vehicles generally have higher participation rates in recycling programs, thereby complementing our initiative to expand our recycling capabilities.

Fleet Electrification

We believe we are taking a leadership position in electric technology innovation for our recycling and waste collection fleet. This is a critical step toward reducing our environmental impact through lower fleet emissions. We believe it will also improve our total cost of ownership through reduced operating costs and maintenance, while providing a competitive advantage in certain communities. We are partnering with multiple manufacturers to pilot electric-powered recycling and waste trucks. As electric-vehicle technology continues to develop, we expect to further deploy electrification within our fleet. As of December 31, 2025, we operated more than 180 electric-collection vehicles and had 32 commercial-scale electric charging facilities.

Standardized Maintenance

Based on an industry trade publication, we operate the third largest vocational truck fleet in the United States. As of December 31, 2025, our average fleet age for recycling and waste collection vehicles in years, by service line of business, was as follows:

Approximate Number of Vehicles Approximate Average Age

OneFleet, our standardized vehicle maintenance program, enables us to use best practices for fleet management, truck care and maintenance. Through standardization of core functions, we believe we can minimize variability in our maintenance processes, resulting in higher vehicle quality and a lower environmental footprint while extending the average service life of our fleet. Additionally, our focus on preventative maintenance is improving the reliability of our fleet and enabling us to provide superior service to our customers, differentiating us from our competition.

People and Talent Focus

Being human-centered is at the core of our robust people and talent agenda. We strive to maintain an environment that attracts and retains the best talent. Our approximately 42,000 full-time employees are a critical component in successfully executing our strategy and running our operations. We work hard to remain a company where the best people, with exceptional talents and diverse backgrounds, can thrive and foster a culture of caring where people feel respected, supported and encouraged to bring their best selves to work every day.

We are dedicated to driving our people and talent agenda, which includes (1) sustaining a safe, inclusive and diverse culture, (2) maintaining a highly engaged workforce, (3) developing our talent through learning and development experiences and (4) offering rewards that attract and retain the best workforce. We review key progress metrics such as engagement and turnover

5

TableofContents

and regularly report on these metrics to our Board of Directors. This level of reporting holds all of our leaders accountable for the continued growth and development of our people.

Inclusion and Diversity

We believe the composite strength of our employees’ ideas, built on their unique experiences and backgrounds, is essential to our ability to meet and anticipate our customers’ needs.We are proud of the diversity of our frontline workforce, as it closely represents the demographics of the communities we serve. Our commitment to inclusion and diversity starts at the top of our organization, as outlined in our Mission of Supporting an Inclusive Culture (MOSAIC), established in 2013 and supported by the MOSAIC Council. The MOSAIC Council consists of leaders from across the Company who serve as ambassadors and thought partners for inclusion and diversity. This enables us to continue to develop new strategies and activities that are tied to the needs of our employees, customers and business with the goal of creating an even more inclusive work environment and diverse workforce.

We support inclusion and connectivity through our Business Resource Groups (BRG) and focus on the involvement of our field locations in all of our BRGs, including Women of Republic, VALOR (Veterans, Advocacy, Learning, Outreach and Recruiting), UNIDOS, the Black Employee Network, AAPI (Asian American and Pacific Islander) and PRISM in support of the LGBTQ+ community.

Employee Engagement

We believe an engaged workforce is a key element of our success as engaged employees deliver better customer service and are more productive. We measure employee engagement through a third-party survey, assessing employee sentiment on a variety of topics such as pride for the Company, job satisfaction and intention to stay. Our data reinforces that business units with a highly engaged workforce experience less turnover. We also found that employees whose leaders are highly inclusive are more likely to speak up and share their perspective. Regularly hearing from our employees enables us to understand how to support and strengthen an exceptional employee experience. Our goal is to achieve and maintain employee engagement scores at or above 88 by 2030. Our average employee engagement score was 87 in 2025, which is above a national benchmark by eight points. Approximately 99% of our employees participated in the engagement survey process in March 2025 and 97% in September 2025, which are 24% and 22% higher than the national benchmark, respectively. Employee engagement is a core part of our business strategy, which is why we compensate our General Managers, in part, on their employee engagement scores. This reinforces our commitment for leaders to listen and take action on employee feedback and helps to ensure that our leaders are held accountable and rewarded for their efforts to drive a more engaged workforce.

Talent Development

We are committed to providing our employees with opportunities to develop throughout their careers. Our programs, including new hire onboarding and new leader assimilation, reinforce our Company values, expectations and business approach. We relaunched our successful Leadership Fundamentals program in 2022, targeting field leaders. With a goal of reaching all leaders through this program, more than 1,200 leaders completed this training in 2025, with approximately 650 additional leaders slated to participate in 2026. Targeted development experiences support the growth of people in key roles, including Driver Training, Technician Training, Supervisor Training, Sales Acceleration and General Manager Onboarding, among others. We believe these programs provide the fundamental skills necessary to be successful across roles. Additionally, to meet the specific needs of the business, we opened a comprehensive Technical Training Institute in April 2021 where we train and develop our technicians. We have had 398 participants in the course since its inception.

Our leadership programs are a critical part of growing our people. We remain focused on attracting, hiring and developing early career leaders. Our rotational training and development programs, including our General Manager Acceleration Program (GMAP) and Operations Manager Acceleration Program, help us attract, develop and advance a diverse and talented pool of individuals from across our organization. Our Executive Leadership team sponsors these programs, providing visibility and support for the career advancement of our high-potential talent across the organization. Since the beginning of these programs in 2017, 135 leaders have graduated into leadership positions. Additionally, our MBA intern program, with 60 participants since 2019, introduces strong talent to the organization and is a path of opportunity into the GMAP program. We have found that these programs and experiences help ensure that the next generation of leaders build the necessary skills and experiences to be successful in their roles today and in the future.

We continue to leverage innovative training methods using mixed mediums to deliver trainings and instruction to our employees across the country. We remain committed to expanding employee participation in learning programs that are relevant to our business strategy and contribute to career advancement for our employees.

Compensation and Benefits

We offer compensation and benefits that help improve our employees' overall financial, physical and emotional wellbeing, as well as recognize hard work with opportunities to grow. Our commitment to paying market competitive wages enables us to

6

TableofContents

attract and hire talent all across the country. Our approach to paying for performance supports our focus on pay equity. Our compensation packages are designed to provide employees with a stable and livable wage and growth potential. Our focus on wellness also provides our employees with a competitive paid time off plan, access to preventative care, advice on financial planning and support for mental health, contributing to our efforts to provide a total rewards package that improves and enhances the lives of our employees.

Differentiating Capabilities

To effectively execute our strategic plan, we prioritize the development and investment in capabilities that will differentiate us in the marketplace. These capabilities include – (1) customer zeal, (2) digital and (3) sustainability.

Customer Zeal

The goal of customer zeal is to drive customer loyalty by offering differentiated products and services specifically designed to meet our customers’ needs. We offer a broad set of environmental services across the United States and Canada and can thus serve as many of our customers' sole provider, which we believe sets us apart in the industry. Customers appreciate our track record of safe and environmentally compliant operations, with the expertise to manage complex waste streams. We believe our value proposition increases customer loyalty and willingness to pay for our differentiated offerings. Customer zeal is a cultural commitment to enable and empower our employees to own their role in the customer experience.

To help our sales team identify specific customer needs and configure the right offering, we use a Priority Based Selling (PBS) technique and our Capture pricing tool nationwide.

•PBS enables us to identify and segment customers’ buying priorities and attract customers that are willing to pay for enhanced offerings.

•Capture is a cloud-based pricing tool that creates a more professional sales experience, helps realize better pricing levels at the point of sale and provides enhanced controls over the price quoting process.

We continue to expand our offering of products and services to meet customer demand for a single provider for their environmental services needs. We have made progress on this front, including through our continued expansion of our environmental solutions segment. Our acquisitions of leading environmental solutions providers enable us to offer a complete set of products and services, including treatment, recycling and disposal of hazardous, non-hazardous and specialty waste. For services that we do not provide, we fulfill demand through our alliance partnerships while maintaining the customer-facing relationship.

To help ensure a consistent customer experience, we have invested in our customer service capabilities and our centralized Customer Experience function. This modern technology provides our customer service employees with the tools and capabilities they need to provide better levels of service through a variety of communication channels. The standardized approach enhances the customer experience and provides us a platform to reduce the cost to service our customers.

To help ensure our efforts are making an impact and building customer loyalty, we solicit feedback from our customers, including Net Promoter ScoreSM, so that every General Manager receives timely, relevant feedback that allows him or her the ability to reach out to customers directly and address issues immediately.

Digital

By prioritizing our digital capabilities, we seek to provide a consistent experience across our business. We believe investments in our digital platforms support improved processes for our employees that lead to enhanced employee engagement and enable our customers to do business with us through more channels and with better access to information, ultimately driving increased customer loyalty.

By increasing the ease of use and functionality of our web-based market presence, we believe we enhance customer satisfaction, interaction and connectivity while lowering our costs. These tools reinforce to our customers that they can rely on us to handle their recycling and waste services needs in a way that is easy and convenient for them.

•Our website and mobile app are online account management tools, allowing customers access to their accounts and our services.

•Our e-commerce sales channel allows customers to secure services on a real-time basis, provides capabilities to meet our customers' evolving buying preferences and provides a lower cost sales channel.

We are leveraging technology to digitally connect our customers, drivers, logistics analysts, supervisors and trucks via our "RISE" dispatch platform and in-cab technology. With the roll-out of this technology we have improved productivity through more real-time routing information and data visualization tools, increasing customer connectivity and enabling automated

TableofContents

service verification communications and enhancing the employee experience by providing better tools and technology designed around employee interaction.

We have installed advanced technology on recycling and waste collection vehicles that utilizes cameras to identify recycling contamination and overfilled containers. We expect this technology will reduce recycling contamination over time and drive incremental revenue.

In 2025, we advanced the deployment of our “MPower” enterprise asset management system to digitally connect our maintenance team to our collection fleet of vehicles. This technology is designed to streamline our fleet maintenance record keeping and parts management processes and allow improved technician efficiency and enhanced warranty recovery across our fleet.

Sustainability

The goal of our differentiating sustainability capabilities is to provide our customers with fully integrated sustainable solutions that support a cleaner, safer and healthier world. We have long been a leader in environmental services and sustainability. We introduced our Elements of Sustainability, the foundation of our sustainability platform, in 2014. Our elements, Safety, Talent, Climate Leadership and Communities, are deeply integrated into our business and anchor our ambitious 2030 sustainability goals.

Our Board of Directors’ Sustainability & Corporate Responsibility Committee has oversight responsibility with respect to our sustainability performance, our corporate responsibilities and our role as a socially responsible organization. The Committee meets at least quarterly to be updated on progress and conducts a formal comprehensive review of the Company’s performance in these areas on an annual basis.

Our 2030 Sustainability Goal

As we grow, so does our opportunity to make a meaningful, positive impact on the environment and society. Our ambitious 2030 goals are aligned with the UN Sustainable Development Goals(1) and our greenhouse gas reduction goal is aligned with the Paris Agreement. Each goal is aligned with one of the Company's elements of sustainability. Together they are designed to significantly benefit the environment and society, while enhancing the foundation and profitability of our business for the long-term.

•Safety Amplified: Achieve zero annual employee fatalities

•Incident Reduction: Reduce OSHA Total Recordable Incident Rate (TRIR) to 2.0 or less by 2030

•Engaged Workforce:Achieve and maintain employee engagement scores at or above 88 by 2030

•Emissions Reduction: Reduce absolute Scope 1 and 2 greenhouse gas emissions 35% by 2030(2), which was approved by SBTi(3, 4)

Cash Utilization Strategy

We take a consistent and balanced approach to capital allocation to drive long-term, sustainable value for our shareholders. The predictability of our free cash flows allows us to efficiently execute our capital allocation strategy, which includes investing in value-creating acquisitions and returning free cash flow to our shareholders through dividends and share repurchases. We are committed to an efficient capital structure and maintaining our investment grade credit ratings on our senior debt, which was rated A- by Standard & Poor’s Ratings Services, A- by Fitch Ratings, Inc. and A3 by Moody’s Investors Service, Inc. Such ratings have allowed us, and should continue to allow us, to readily access capital markets at competitive rates.

We manage our free cash flow by ensuring that capital expenditures and operating asset levels are appropriate in light of our existing business and growth opportunities and by closely managing our working capital.

Dividends

In July 2025, our Board of Directors approved an increase in the quarterly dividend to $0.625 per share, which represents an increase of approximately 8% over the prior year. This increase represented the 22nd consecutive year of a dividend increase. Over the last five years, our dividends have increased at a compounded annual growth rate of 6.3%. We expect to continue paying quarterly cash dividends and may consider additional dividend increases if we believe they will enhance shareholder value.

Share Repurchases

In October 2023, our Board of Directors approved a $3.0 billion share repurchase authorization effective starting January 1, 2024, and extending through December 31, 2026. Share repurchases under the current program may be made through open market purchases or privately negotiated transactions in accordance with applicable federal securities laws. While the Board of Directors has approved the program, the timing of any purchases, the prices and the number of shares of common stock to be purchased will be determined by our management, at its discretion, and will depend upon market conditions and other factors. The share repurchase program may be extended, suspended or discontinued at any time. On a quarterly basis, our Board of Directors reviews the parameters around which we repurchase our shares. Refer to Item 5. Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities for repurchase authority remaining as of December 31, 2025.

Shareholder Value

We are committed to creating long-term shareholder value by generating consistent earnings and cash flow growth while continually improving returns on invested capital. Our incentive compensation programs are aligned with these objectives at all levels of management. We have an active shareholder outreach program and routinely interact with shareholders on a number of matters, including environmental, social, governance, talent and executive compensation.

Comprehensive Environmental Services

We serve customers with a strong, vertically-integrated operating platform and offer a complete set of products and services, including the collection and processing of recyclable, solid waste and industrial waste materials; transportation and disposal of non-hazardous and hazardous waste streams; and other environmental solutions. We offer a wide array of products and services with a proven track record in safety, compliance and environmental stewardship.

Recycling & Waste Services

We have a strong, national, vertically-integrated operating platform that allows us to compete more effectively and efficiently in the local markets in which we operate. Where appropriate, we seek to achieve a high rate of internalization by managing material streams from the point of collection through recycling processing or disposal. During the year ended December 31, 2025, approximately 67% of the total solid waste volume we collected was disposed at landfills we own or operate (internalization). Our fully integrated markets generally have a lower cost of operations and more favorable cash flows than our markets that are not fully integrated. Through acquisitions, landfill operating agreements and other market development activities, we create market-specific, vertically-integrated operations typically consisting of one or more collection operations,

9

TableofContents

transfer stations and landfills. We also operate recycling centers in markets where diversion of waste is a priority, customers are willing to pay for the service and we can earn an appropriate return on our investment.

Collection Services

We provide residential, small-container and large-container collection services through 377 collection operations. In 2025, approximately 68% of our total revenue was derived from our collection business, of which approximately 18% of our total revenue related to residential services, approximately 30% related to small-container services, approximately 19% related to large-container services and approximately 1% related to other collection services.

Our residential collection business involves the curbside collection of material for transport to transfer stations, or directly to recycling centers, organics processing facilities, or landfills. We typically perform residential collection services under contracts with municipalities, which we generally secure through competitive bids, which give us exclusive rights to service all or a portion of the homes in the municipalities. These contracts usually range in duration from one to five years, although some of our exclusive franchises are for significantly longer periods. We also perform residential services on a subscription basis, in which individual households contract directly with us. The fees received for subscription residential collection are based primarily on the market, collection frequency, type of service, the distance to the disposal facility and the cost of processing or disposal. In general, subscription residential collection fees are paid quarterly in advance by the customers receiving the service.

In our small-container business, we supply our customers with recycling and waste containers of varying sizes. We typically perform small-container collection services under one- to three-year service agreements, and fees are determined based on a number of factors including the market, collection frequency, type of equipment furnished, type and volume or weight of the material collected, transportation costs and the cost of processing or disposal. Our small-container services are typically offered to small business complexes, multi-family housing and strip malls and include industries such as restaurants, retail, real-estate and professional and other services.

Our large-container collection business includes both recurring and temporary customer relationships. For the recurring portion, we supply our customers with recycling and waste containers of varying sizes and rent compactors to large generators of material. We typically perform the collection services under one- to three-year service agreements, and fees are determined based on a number of factors including the market, collection frequency, type of equipment furnished, type and volume or weight of the material collected, transportation costs and the cost of processing or disposal. Our recurring large-container services are typically offered to larger facilities, hotels and office buildings and include industries such as manufacturing, retail, hospitality, professional and other services.

For the temporary portion of our large-container collection business, the majority of the material relates to construction and demolition activities and is typically event-driven. We provide temporary collection services on a contractual basis with terms ranging from a single pickup to one-year or longer.

Transfer Services

We own or operate 255 transfer stations. Revenue at our transfer stations is primarily generated by charging tipping or disposal fees, which accounted for approximately 5% of our revenue during 2025. Our collection operations deposit material at these transfer stations, as do other private and municipal haulers, for compaction and transfer to disposal sites or recycling centers. Transfer stations provide collection operations with a cost-effective means to consolidate material and reduce transportation costs while providing our landfills with an additional mechanism to extend their geographic reach.

When our own collection operations use our transfer stations, this improves internalization by allowing us to retain fees we would otherwise pay to third-party disposal sites. It also allows us to manage costs associated with material disposal because: (1) transfer trucks have larger capacities than collection trucks, allowing us to deliver more material to the landfill or processing center in each trip; (2) material is accumulated and compacted at strategically located transfer stations to increase efficiency; and (3) we can retain volume by transporting the material to one of our own landfills or processing centers rather than to a competitor’s.

Recycling Processing Services

We own or operate 79 recycling centers. These centers generate revenue through the processing and sale of old corrugated containers (OCC), old newsprint (ONP), aluminum, glass and other materials, which accounted for approximately 3% of our total revenue during 2025. Approximately 83% of our total recycling center volume is fiber based and includes OCC, ONP and other mixed paper. During 2025, we processed and sold 2.2 million tons, excluding glass and organics, from our recycling centers. An additional 1.8 million tons were collected by us and delivered to third parties. We are investing in innovative recycling technology and have expanded our organics operations to help customers meet their diversion goals. We processed 1.1 million tons and sold 0.4 million tons of organic materials, respectively, through our organics infrastructure in 2025.

10

TableofContents

Changing market demand for recycled commodities causes volatility in commodity prices. At current volumes and mix of materials, we believe a $10 per ton change in the price of recycled commodities would change both annual revenue and operating income by approximately $13 million.

In certain instances, we issue recycling rebates to our municipal or large-container customers, which can be based on the price we receive upon the final sale of recycled commodities, a fixed contractual rate or other measures. We also receive rebates when we dispose of recycled commodities at third-party processing facilities.

We have met increased consumer demand for recycling services by integrating recycling components across our collection service offerings. Our goal is to provide a complete material stream management solution to our customers in a vertically integrated, environmentally sustainable way.

We continue to invest in proven technologies to control costs and to simplify and streamline recycling for our customers. For example, robotics and advanced sorting equipment, such as disk screens, magnets and optical sorters, identify and separate different kinds of paper, metals, plastics and other materials to increase efficiency and maximize our recycling efforts.

Landfill Services

We own or operate 207 active landfills. Our landfill tipping fees charged to third parties accounted for approximately 12% of our revenue during 2025. As of December 31, 2025, we had 41,158 estimated permitted acres and estimated total available disposal capacity of 5.0 billion in-place cubic yards. The in-place capacity of our landfills is subject to change based on engineering factors, requirements of regulatory authorities, our ability to continue to operate our landfills in compliance with applicable regulations and our ability to successfully renew operating permits and obtain expansion permits at our sites. Some of our landfills accept non-hazardous special waste, including utility ash, asbestos and contaminated soils.

Most of our active landfill sites have the potential for expanded disposal capacity beyond the currently permitted acreage. We monitor the availability of permitted disposal capacity at each of our landfills and evaluate whether to pursue an expansion at a given landfill based on estimated future waste volumes and prices, market needs, remaining capacity and the likelihood of obtaining an expansion. To satisfy future disposal demand, we are seeking to expand permitted capacity at certain landfills; however, all proposed or future expansions may not be permitted.

We also have responsibility for 124 closed landfills, for which we have associated closure and post-closure obligations.

Environmental Solutions

We have the capabilities to address the complex environmental and sustainability needs of our customers. Our environmental solutions offerings include collection, treatment, consolidation, disposal and recycling of hazardous and non-hazardous waste; field and industrial services; equipment rental; emergency response and standby services; and in-plant services. Environmental solutions volume is generated by the daily operations of industrial, petrochemical and refining facilities and oil and natural gas exploration and production sites, including maintenance, plant turnarounds and capital projects. Volume also is generated by private and government funded projects including site remediation, redevelopment or emergency spill response. In 2025, approximately 11% of our revenue was derived from environmental solutions.

Waste Treatment & Disposal

We own or operate 6 active hazardous waste landfills, 9 active energy waste landfills, 2 treatment, recovery and disposal facilities, 24 treatment, storage and disposal facilities, 5 salt water disposal wells, 15 deep injection wells, and 9 industrial wastewater treatment facilities. We recycle, treat and dispose of hazardous and non-hazardous industrial wastes. The waste streams handled include substances which are classified as “hazardous” because of their corrosive, ignitable, reactive or toxic properties and other wastes subject to federal, state and provincial environmental regulation. The waste we handle comes in solid, liquid and sludge form and can be received in a variety of containerized and bulk forms and transported to our facilities by truck and rail.

We also operate thermal desorption units that recover oil and metal bearing catalyst from refinery and other organic and oil-based waste. The recycled oil and recycled catalyst are sold to third parties.

Field Services

Our field services include a wide range of specialty and total waste management services provided to refineries, chemical plants, manufacturing plants, pharmaceutical manufacturers, technology companies, research laboratories and other government, commercial and industrial facilities either on-site or at our network of facilities. These services include industrial cleaning and maintenance, retail services, lab pack, site remediation, equipment cleaning and maintenance services, specialty equipment rental, transportation and emergency response.

11

TableofContents

As an integral part of our services, we employ highly trained staff and operate a network of service centers that characterize, package and collect hazardous and non-hazardous wastes from customers and transport such wastes to and between our facilities for treatment or bulking for shipment to final disposal locations.

Sustainability Innovation

We are uniquely positioned to offer products and services to address the complex sustainability needs of our customers, including offerings that allow for greater material circularity and support decarbonization. We believe demand for post-consumer content in consumer packaging and low carbon energy alternatives continues to increase. We are able to invest independently or through joint ventures to create solutions for the evolving marketplace.

Circularity

In 2025, we commenced operations at our second Polymer Center in Indianapolis, Indiana and began construction at our third Polymer Center in Allentown, Pennsylvania. Through its Polymer Centers, Republic is the first company to manage the plastics stream through an integrated process from curbside collection of recycled material to production and delivery of high-quality recycled content for consumer packaging. Rigid plastics – polyethylene terephthalate (PET), high-density polyethylene (HDPE) and polypropylene (PP) – collected from residential and commercial customers and sorted at local recycling facilities are delivered to the Polymer Center for secondary processing. Each facility is expected to produce more than 100 million pounds per year of recycled plastic, including 100% post-consumer PET flake delivered to the food-grade marketplace to enable bottle-to-bottle circularity. In addition, HDPE and PP packaging such as detergent jugs or butter tubs, which today are collected in multicolored bundles, can be separated by plastic type and color. We plan to commence operations at our Allentown, Pennsylvania Polymer Center in 2027.

In 2023, we announced the creation of Blue Polymers, LLC, a joint venture with Ravago, that will further advance circularity in the plastics industry. The Blue Polymers facilities will utilize the color-sorted recycled HDPE and PP from our Polymer Centers to create custom recycled resins for consumer packaging and other applications. The process is expected to convert recycled HDPE and PP into fully formulated products for use in both food-grade and non-food-grade sustainable applications. In 2025, operations commenced at the first Blue Polymers facility in Indianapolis, Indiana, and additional Blue Polymers facilities are planned to open over the coming years. Products are expected to include custom-blended and compounded materials for individual customers to help them achieve their sustainability goals and comply with federal, state or local requirements for recycled content.

Decarbonization

Our customers are increasingly looking for decarbonization solutions, and we are leveraging our network of landfills to meet that need. Republic is committed to harnessing landfill gas, a natural byproduct of decomposing waste, and converting it to energy. More than 89% of our landfill acreage is covered by gas collection systems. Collecting and converting landfill gas into renewable energy provides economic and environmental benefits, including reducing fugitive greenhouse gas emissions.

As of December 31, 2025, we were engaged in 77 landfill gas-to-energy projects at our landfills. The majority of these projects were developed and are owned and operated by a third party, where we earn a royalty from our supply of landfill gas to the renewable energy production facilities. We presently have more than 30 landfill gas-to-energy projects in development that are expected to begin operations in the coming years. Many of these projects produce or are expected to produce renewable natural gas, a low carbon, pipeline-quality fuel that’s fully interchangeable with fossil fuel-derived natural gas; it can be used as a transportation fuel in commercial fleets, including our own.

We also are producing renewable energy at our landfills through solar projects we host at seven sites, which generate clean electricity for local communities.

Other Services

Other revenue consists primarily of National Accounts revenue generated from nationwide or regional contracts in markets outside our operating areas where the associated material handling services are subcontracted to local operators. Consequently, substantially all of this revenue is offset with related subcontract costs, which are recorded in cost of operations.

Competition

We operate in a competitive industry. Competition in the environmental services industry comes from a few other large, national publicly-owned companies, several regional publicly- and privately-owned companies and thousands of small privately-owned companies. In any given market, competitors may have larger operations and greater resources. In addition, we

12

TableofContents

compete with municipalities that maintain material collection or disposal operations. These municipalities may have financial advantages due to the availability of tax revenue and greater opportunities for tax-exempt financing.

We compete for collection accounts primarily based on our product offering, quality of service and price. From time-to-time, our competitors reduce the price of their services in an effort to expand market share or to win a competitively bid municipal contract. Our ability to maintain and increase prices in certain markets may be impacted by our competitors’ pricing policies. This may have an effect on our future revenue and profitability.

Seasonality and Severe Weather

Our operating revenues tend to be somewhat higher in the summer months, primarily due to higher volumes of construction and demolition waste. The volumes of large-container and residential recycling and waste in certain regions of the country also tend to increase during the summer months. Our second and third quarter revenues and results of operations typically reflect this seasonality.

We provide essential environmental services in the communities we serve and our operations can be adversely affected by periods of inclement or severe weather and natural disasters, which could increase the volume of material collected under our existing contracts (without corresponding compensation), delay the collection and disposal of material, reduce the volume of material delivered to our disposal sites or delay the construction or expansion of our landfill sites and other facilities. These risks may increase with the physical impacts of climate change. The impacts from adverse weather and natural disasters have the potential to last several months and to affect several facilities. We have business continuity plans in place for severe weather, natural disasters and other emergencies—hurricanes, tornadoes, flooding, winter storms, earthquakes and wildfires, among others—to help limit disruptions in our operations andhelpensure the continuity of our services. Our operations can also be favorably affected by severe weather and natural disasters, which could increase the volume of material in situations where we are able to charge for our additional services. Refer to our TCFD Report for more information on climate impacts and our risk management strategies, available at republicservices.com/sustainability. The information contained on our website shall not be deemed incorporated by reference in this Annual Report on Form 10-K or in any other filing we make under the Exchange Act.

Regulation

Our facilities and operations are subject to a variety of federal, state, provincial and local requirements that regulate, among other things, the environment, public health, safety, zoning and land use. Operating and other permits, licenses and other approvals generally are required for landfills and transfer stations, recycling centers, certain waste collection vehicles, fuel storage tanks and other equipment and facilities that we own or operate. These permits are subject to denial, revocation, modification and renewal in certain circumstances. Any revocation, modification or denial of permits could have a material adverse effect on us. Federal, state, provincial and local laws and regulations vary, but generally govern wastewater or storm water discharges, air emissions, the handling, transportation, treatment, storage and disposal of hazardous and non-hazardous waste and the remediation of contamination associated with the release or threatened release of hazardous substances. These laws and regulations provide governmental authorities with strict powers of enforcement, which include the ability to revoke or decline to renew any of our operating permits, obtain injunctions, or impose fines or penalties in the event of violations, including criminal penalties. The United States EPA and various other federal, state, provincial and local authorities administer these regulations. Regulations with respect to hazardous waste are particularly relevant for our Group 3 reportable segment that provides treatment, recycling and disposal of hazardous waste.

In order to comply with these regulations, we must incur substantial capital expenditures relating to our vehicles, landfills, transfer stations, recycling centers and other assets, and in connection with our capping, closure, post-closure and environmental remediation activities. Compliance with existing and future legal and regulatory requirements, including changes relating to per- and polyfluoroalkyl substances (commonly referred to as PFAS) and other chemicals of emerging concern, and limitations or bans on disposal of certain types of wastes or on the transportation of waste, could increase our costs to operate or require additional capital expenditures.

A decrease in regulation may lower barriers to entry for our competitors. Further, we compete with counties and municipalities that operate their own collection and disposal facilities, and have the benefits of tax revenue and greater opportunities for tax-exempt financing.

We strive to conduct our operations in compliance with applicable laws, regulations and permits. However, from time to time we have been issued citations or notices from governmental authorities that have resulted in the need to expend funds for remedial work and related activities at various landfills and other facilities or in the need to expend funds for fines, penalties or settlements. Citations and notices may be issued in the future, notwithstanding our strong regulatory compliance efforts. We have established final capping, closure, post-closure and remediation reserves that we believe, based on currently available information, will be adequate to cover our current estimates of regulatory costs; however, actual costs may exceed our reserves.

13

TableofContents

Federal Regulation

The following summarizes the primary federal, environmental and occupational health and safety-related statutes that affect our facilities and operations:

•The Solid Waste Disposal Act, including the Resource Conservation and Recovery Act (RCRA). RCRA establishes a framework for regulating the handling, transportation, treatment, storage and disposal of hazardous and non-hazardous solid waste, and requires states to develop programs to ensure the safe disposal of solid waste in sanitary landfills.

Subtitle C of RCRA establishes a framework for regulating the disposal of hazardous waste, and Subtitle D of RCRA establishes a framework for regulating the disposal of municipal solid waste. Regulations under Subtitle C set requirements for hazardous waste generators, transporters and treatment, storage and disposal facilities. Regulations under Subtitle D currently include minimum comprehensive solid waste management criteria and guidelines, including location restrictions, facility design and operating criteria, final capping, closure and post-closure requirements, financial assurance standards, groundwater monitoring requirements and corrective action standards. The EPA may authorize states to implement certain hazardous waste requirements of Subtitle C, and if a state program does not exist, the EPA directly implements the hazardous waste requirements. Nearly all of the states in which we operate have implemented permit programs pursuant to RCRA and Subtitles C and D. These state permit programs may include landfill requirements that are more stringent than those of Subtitles C and D. Our failure to comply with any of these environmental requirements at any of our locations may lead to temporary or permanent loss of an operating permit, which would result in costs in connection with securing new permits, reduced revenue from lost operational time and increased third party disposal costs.

All of our planned landfill expansions and new landfill development projects have been engineered to meet or exceed Subtitles C and D requirements, as applicable. Operating and design criteria for existing operations have been modified to comply with these regulations. Compliance with Subtitles C and D regulations has resulted in increased capital expenditures and operating costs and may in the future require substantial additional expenditures in addition to other costs normally associated with our waste management activities.

•The Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA). CERCLA, among other things, provides for the cleanup of sites from which there is a release or threatened release of a hazardous substance into the environment. CERCLA may impose strict joint and several liability for the costs of cleanup and for damages to natural resources upon current owners and operators of a site, parties who were owners or operators of a site at the time the hazardous substances were disposed of, parties who transported the hazardous substances to a site and parties who arranged for the disposal of the hazardous substances at a site. Under the authority of CERCLA and its implementing regulations, detailed requirements apply to the manner and degree of investigation and remediation of facilities and sites where hazardous substances have been or are threatened to be released into the environment. Liability under CERCLA is not dependent on the existence or disposal of only hazardous wastes, but also can be based upon the existence of small quantities of more than 700 substances currently characterized by the EPA as hazardous, many of which are found in common household waste. The EPA may also designate additional substances as hazardous; in 2024, the EPA finalized a rule that designated two PFAS as hazardous substances. Among other things, CERCLA authorizes the federal government to investigate and remediate sites at which hazardous substances have been or are threatened to be released into the environment, or to order persons potentially liable for the cleanup of the hazardous substances to do so themselves. In addition, the EPA has established a National Priorities List of sites at which hazardous substances have been, or are threatened to be, released and which require investigation or cleanup.

CERCLA liability is strict liability. It can be founded upon the release or threatened release, even as a result of unintentional, non-negligent or lawful action, of hazardous substances, including very small quantities of such substances. Thus, even if we have never knowingly transported or received hazardous substances, it is possible that hazardous substances have been deposited or released at landfills or other facilities that we presently or historically have owned or operated, or at properties owned by third parties to which we have transported waste. Therefore, we could be liable under CERCLA for the cost of cleaning up, or protecting against the release of, such hazardous substances at such sites and for damages to natural resources, even if those substances were deposited at our facilities before we acquired or operated them. The costs of a CERCLA cleanup can be very expensive and can include the costs of disposing of hazardous substances at appropriately-licensed facilities. Given the difficulty of obtaining insurance for environmental impairment liability, any such liability could have a material effect on our business, financial condition, results of operations and cash flows.

•The Federal Water Pollution Control Act of 1972 (the Clean Water Act). This act regulates the discharge of pollutants from a variety of sources, including solid waste disposal sites, into streams, rivers and other waters of the United States. Runoff from our landfills and transfer stations that is discharged into surface waters through discrete conveyances must be covered by discharge permits that generally require us to conduct sampling and monitoring, and,

14

TableofContents

under certain circumstances, to reduce the quantity of pollutants in those discharges. Storm water discharge regulations under the Clean Water Act require a permit for certain construction activities and for runoff from industrial operations and facilities, which may affect our operations. If a landfill or transfer station discharges wastewater through a sewage system to a publicly-owned treatment works, the facility must comply with discharge limits imposed by that treatment works. In addition, states may adopt groundwater protection programs under the Clean Water Act or the Safe Drinking Water Act that could affect the manner in which our landfills monitor and control their waste management activities. Furthermore, if development at any of our facilities alters or affects wetlands, we may be required to secure permits before such development starts. In these situations, permitting agencies may require mitigation of wetland impacts.

•The Clean Air Act. The Clean Air Act imposes limitations on emissions from various sources, including landfills. In 1996, the EPA promulgated regulations that require large municipal solid waste landfills to install landfill gas monitoring systems along with landfill gas control systems unless emissions are below established thresholds. These regulations apply to landfills that commenced construction, reconstruction or modification on or after May 30, 1991, and, principally, to landfills that can accommodate 2.5 million cubic meters or more of municipal solid waste. The regulations apply whether the landfills are active or closed. The date by which each affected landfill must have a gas collection and control system installed and made operational varies depending on calculated emission rates at the landfill. In July 2016, the EPA issued final amendments to its regulations that require large landfills that commenced construction, reconstruction, or modification on or after July 17, 2014 to capture additional landfill gas to reduce emissions of methane and certain non-methane gases, which are recognized as greenhouse gases. In a separate rule finalized at the same time, the EPA issued updates to its 1996 Emission Guidelines to reduce emissions of landfill gas from existing active landfills. These and other efforts to curtail the emission of greenhouse gases and to ameliorate the effect of climate change may require our landfills to deploy more stringent emission controls and monitoring systems, with resulting capital or operating costs. Many state regulatory agencies also currently require monitoring systems for the collection and control of certain landfill gas. Certain of these state agencies are also implementing greenhouse gas control regulations that would also apply to landfill gas emissions. See Item 1A, Risk Factors – Regulation of greenhouse gas emissions and other governmental regulations could impose costs on our operations, the magnitude of which is difficult to estimate, in this Annual Report on Form 10-K.

In addition, our vehicle fleet may become subject to higher efficiency standards or other carbon-emission restrictions. Over the past decade, the EPA and the National Highway Traffic Safety Administration (NHTSA) have adopted regulations mandating the reduction of vehicle tail pipe emissions as a means of reducing greenhouse gas emissions. The regulations take the form of fuel economy standards. The EPA and the NHTSA have developed fuel economy standards in two vehicle categories: (1) passenger automobiles and light-duty trucks (collectively, light-duty vehicles); and (2) heavy-duty trucks, including solid waste collection vehicles and tractor trailers. The Trump Administration has proposed to repeal certain EPA vehicle emissions standards and decrease certain NHTSA fuel economy standards. We own and operate vehicles in both categories. EPA and NHTSA periodically issue rules covering additional model years, typically increasing the stringency of the relevant vehicle standards, and those rules are frequently challenged in court.

•The Occupational Safety and Health Act of 1970 (OSHA). This act authorizes the Occupational Safety and Health Administration of the United States Department of Labor to promulgate occupational safety and health standards. A number of these standards, including standards for notices of hazardous chemicals and the handling of asbestos, apply to our facilities and operations.

State and Local Regulation

Each state in which we operate has its own laws and regulations governing solid waste disposal, water and air pollution, and, in most cases, releases and cleanup of hazardous substances and liabilities for such matters. States also have adopted regulations governing the design, operation, maintenance and closure of landfills and transfer stations. Some counties, municipalities and other local governments have adopted similar laws and regulations. In addition, our operations may be affected by the trend in many states toward requiring solid waste reduction and recycling programs. For example, several states have enacted laws that require counties or municipalities to adopt comprehensive plans to reduce, through solid waste planning, composting, recycling or other programs, the volume of solid waste deposited in landfills. Additionally, laws and regulations restricting the disposal of certain waste in solid waste landfills, including yard waste, food waste, newspapers, beverage containers, unshredded tires, lead-acid batteries, electronic wastes and household appliances, have been adopted in several states and are being considered in others. Some jurisdictions have enacted or are considering enacting “extended producer responsibility” regulations, which are designed to obligate producers to fund the post-use life cycle of their products by providing recycling programs for their products. State and municipal governments also have enacted or may enact “organic diversion” regulations that require food waste to be managed separately from the other waste streams, similar to the rules recently enacted in California. Several states have also enacted or are considering “minimum recycled content” regulations mandating certain minimum post-consumer

15

TableofContents

recycled content in certain types of packaging, including California. Legislative and regulatory measures to mandate or encourage waste reduction and recycling also have been considered, or are under consideration by, the United States Congress and the EPA. These regulations may present new opportunities to offer sustainable environmental services to our customers but may require investment of time, effort and money to be able to offer these new solutions, may expose us to additional regulatory requirements and competition from others offering these services, and could involve loss of volume at our landfills.

To construct, operate and expand a landfill, we must obtain one or more construction or operating permits, as well as zoning and land use approvals. These permits and approvals may be burdensome to obtain and to comply with, are often opposed by neighboring landowners and citizens’ groups, may be subject to periodic renewal, and are subject to denial, modification, non-renewal and revocation by the issuing agency. Significant compliance disclosure obligations often accompany these processes. In connection with our acquisition of existing landfills, we may be required to spend considerable time, effort and money to bring the acquired facilities into compliance with applicable requirements and to obtain the permits and approvals necessary to increase their capacity.

Canadian Waste Regulation

Certain of our operations and facilities are subject to, among other regulations, Canadian hazardous and non-hazardous waste regulations. The Canadian federal government regulates issues within federal jurisdiction, including activities that cross provincial boundaries or affect Canada’s relations with other nations. The Canadian provinces and territories also have jurisdiction over environmental matters within their respective boundaries, including primary responsibility for regulation and management of hazardous and non-hazardous waste.

The main federal laws governing waste management are the Canadian Environmental Protection Act, 1999 (CEPA) and the Transportation of Dangerous Goods Act, 1992. Environment and Climate Change Canada (ECCC) is the federal agency with responsibility for environmental matters. CEPA charges ECCC and Health Canada with the protection of human health and the environment and seeks to control the production, importation and use of substances in Canada and their impact on the environment. The Cross-border Movement of Hazardous Waste and Hazardous Recyclable Material Regulations under CEPA control the transboundary movement of hazardous waste and hazardous recyclable materials. These regulations require that anyone proposing to export or import hazardous waste or hazardous recyclable materials or transport them through Canada notify ECCC and obtain a permit to do so.

Certain of our facilities are subject to the Québec Environment Quality Act, the Ontario Environmental Protection Act or the Alberta Environmental Protection and Enhancement Act and their respective regulations. These statutes and regulations regulate the generation, collection, characterization, documentation, transport, storage, treatment, recovery and disposal of hazardous and non-hazardous wastes, establish the requirements for waste management facilities and waste transportation systems and govern actual or potential releases of contaminants in the environment, such as air emissions and soil, groundwater and surface water contamination issues. Similarly, the federal Fisheries Act and provincial statutes such as the Ontario Water Resources Act also regulate releases of contaminants to bodies of water.

Hazardous waste transporters are required to hold permits to operate under the provincial statutes and regulations and are also subject to safety documentation and reporting requirements under provincial law and the federal Transportation of Dangerous Goods Act, 1992.

Maritime Regulations

Our Group 3 operations own and use 68 vessels registered under the United States flag. Accordingly, we are subject to various United States federal, state and local statutes and regulations governing the ownership, operation and maintenance of our vessels. Our United States-flag vessels are subject to the direct jurisdiction of the United States Coast Guard, the United States Customs and Border Protection and the United States Maritime Administration as well as other federal and state agencies. We are also subject to international laws and conventions and the laws of foreign jurisdictions when we operate outside of the United States.

A portion of the operations of our standby services business within Group 3 is conducted in the United States coastwise trade. This is a protected market that is subject to United States cabotage laws that impose certain restrictions on the ownership and operation of vessels in the United States coastwise trade. These laws are principally contained in 46 U.S.C. Chapters 121, 505 and 551 and the related regulations, which are commonly referred to collectively as the “Jones Act.” The Jones Act restricts transportation of merchandise by water or by land and water, either directly or via a foreign port, between points in the United States and certain of its island territories. Subject to limited exceptions, the Jones Act requires that vessels engaged in United States coastwise trade be owned and operated by United States citizens within the meaning of the Jones Act, be built in and registered under the laws of the United States and manned by predominantly United States citizen crews. We have compliance mechanisms in place designed to assist with monitoring and maintaining compliance with the ownership requirements of the Jones Act. Failure to maintain compliance with these ownership requirements could adversely impact our Group 3 operations.

All of our offshore vessels are subject to either United States or international safety and classification standards and sometimes both. United States-flag vessels, barges and crew boats are required to undergo periodic inspections pursuant to United States Coast Guard regulations.

We are also subject to a number of safety, security and environmental laws and regulations, including the Oil Pollution Act of 1990, CERCLA, the Clean Air Act, and the International Ship and Port Facility Security Code (ISPS Code), an amendment to the International Convention for the Safety of Life at Sea (SOLAS) as implemented in the Maritime Transportation and Security Act of 2002 to align United States regulations with those of SOLAS and the ISPS Code. The ISPS Code provides that owners or operators of certain vessels and facilities must provide security and security plans for their vessels and facilities and obtain appropriate certification of compliance. Under the ISPS Code, we perform worldwide security assessments, risk analyses and develop vessel and required port facility security plans to enhance safe and secure vessel and facility operations. Additionally, we have developed security annexes for those United States-flag vessels that transit or work in waters designated as high risk by the United States Coast Guard pursuant to the latest revision of the U.S. Coast Guard’s Maritime Security (MARSEC) Directive 104-6. We believe that additional security and environmental related regulations could be imposed on the maritime industry affecting our Group 3 operations.

Other Regulations

Some of our facilities and operations are subject to the Toxic Substances Control Act of 1976 (TSCA) and the Atomic Energy Act of 1954, as amended (AEA). TSCA regulates the treatment, storage and disposal of polychlorinated biphenyls and asbestos. The AEA assigns the United States Nuclear Regulatory Commission (USNRC) regulatory authority over receipt, possession, use and transfer of certain radioactive materials, including disposal. The USNRC has adopted regulations for licensing commercial low-level radioactive waste regulated under the AEA for disposal and has delegated regulatory authority to certain states, including states where one or more of our facilities are located. The USNRC and United States Department of Transportation regulate the transport of radioactive materials. Shippers must comply with both the general requirements for hazardous materials transportation and specific requirements for transporting radioactive materials.

Many of our facilities own and operate underground storage tanks that are generally used to store petroleum-based products. These tanks can be subject to federal, state and local laws and regulations that mandate their periodic testing, upgrading, closure and removal. In the event of leaks or releases from these tanks, these regulations require that polluted groundwater and soils be remediated. If underground storage tanks we own or operate leak, we could be liable for response costs and, if the leakage migrates onto the property of others, we could be liable for damages to third parties. We are unaware of facts indicating that issues of compliance with regulations related to underground storage tanks will have a material adverse effect on our consolidated financial condition, results of operations or cash flows.

With regard to our solid waste transportation operations, we are subject to the jurisdiction of the Surface Transportation Board and are regulated by the Federal Highway Administration, Office of Motor Carriers and by regulatory agencies in states that regulate such matters. Various state and local government authorities have adopted, or are considering adopting, laws and regulations that would restrict the transportation of solid waste across state, county, or other jurisdictional lines. In 1978, the United States Supreme Court ruled that a law that restricts the importation of out-of-state solid waste is unconstitutional; however, states have attempted to distinguish proposed laws from those involved in and implicated by that ruling. In 1994, the United States Supreme Court ruled that a flow control law, which attempted to restrict solid waste from leaving its place of generation, imposes an impermissible burden upon interstate commerce and is unconstitutional. In 2007, however, the United States Supreme Court upheld the right of a local government to direct the flow of solid waste to a publicly-owned and publicly-operated waste facility. A number of county and other local jurisdictions have enacted ordinances or other regulations restricting the free movement of solid waste across jurisdictional boundaries. Other governments may enact similar regulations in the future. These regulations may cause a decline in volumes of waste delivered to our landfills or transfer stations and may increase our costs of disposal, thereby adversely affecting our operations and our financial results.

We are engaged in 84 landfill gas-to-energy and other renewable energy projects. The production of renewable fuel through certain of these projects is incentivized by the federal Renewable Fuel Standard (RFS) program, which was authorized under the Energy Policy Act of 2005 and expanded through the Energy Independence and Security Act of 2007. Oil refiners and importers are required through the RFS program to blend specified volumes of renewable transportation fuels with gasoline or buy credits, known as renewable identification numbers (RINs), from renewable fuel producers. The amount of RIN credits generated by each gallon of renewable fuel depends on the process and feedstock used to create the specific renewable fuel. There is a market for RINs and, as we and/or our partners produce RFS-compliant renewable fuel, RINs are generated and sold to parties purchasing such RINs to achieve compliance with the RFS program.

Climate and Sustainability Trends

Certain jurisdictions have been updating climate policies toward the goal of reporting and reducing greenhouse gas (GHG) emissions through a broad range of sustainability initiatives. For example, in 2023, California became the first U.S. state to

17

TableofContents

require annual greenhouse gas emission disclosure, as well as biennial disclosure of information on climate-related financial risks. These laws are currently subject to legal challenge. Similar bills have been introduced in other U.S. states; to-date, none have been passed into law.

We believe reducing our impact on the planet and improving the quality of life of its inhabitants are the right things to do, and have committed to heightened emissions reduction goals. Taking into account the challenges associated with quantifying environmental services emissions precisely, we evaluate and offer strategic opportunities to provide our customers with sustainable solutions to reduce their GHG emissions as new regulatory and business developments related to concerns about climate change arise. As a provider of a highly regulated public service, we recognize the importance of broad stakeholder engagement in these endeavors, and we actively seek opportunities for discussion on more sustainable materials management practices. In addition, we cooperate with and support initiatives at the federal and state level that encourage sustainable practices including the production and use of renewable, low-carbon fuels and electricity and the processing of recyclables and organics.

We have long been a leader in sustainability as it relates to environmental services and strive to maintain this reputation. Our sustainability commitments, as well as our progress toward our current goals, are published in our Sustainability Report and accompanying reports and can be found at republicservices.com/sustainability. The information contained on our website shall not be deemed incorporated by reference in this Annual Report on Form 10-K or in any other filing we make under the Exchange Act.

Liabilities Established for Landfill and Environmental Costs

We have established reserves for landfill and environmental costs, which include landfill site final capping, closure and post-closure costs. We periodically reassess such costs based on various methods and assumptions regarding landfill airspace and the technical requirements of Subtitles C and D of RCRA, and we adjust our amortization rates used to expense final capping, closure and post-closure costs accordingly. Based on current information and regulatory requirements, we believe that our recorded reserves for such landfill and environmental expenditures are adequate; however, environmental laws may change, and our recorded reserves may not be adequate to cover requirements under existing or new environmental laws and regulations, future changes or interpretations of existing laws and regulations, or adverse environmental conditions previously unknown to us. Refer to the Material Cash Requirements and Intended Uses of Cash section of our Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in Part II, Item 7 of this Annual Report on Form 10-K and to Note 2, Summary of Significant Accounting Policies, to our audited consolidated financial statements in Part II, Item 8 of this Annual Report on Form 10-K for further information.

Liability Insurance and Bonding

The nature of our business exposes us to the possible risk of liabilities arising out of our operations, including damages to the environment, property, employees or the general public, or those resulting from cyber incidents. We focus on operating safely and prudently, but occasionally we receive claims, alleging damages, negligence or other wrongdoing in the planning or performance of work, which resulted in harm to the environment, property, employees or the general public. These liabilities can be significant. We also could be subject to fines and civil and criminal penalties in connection with alleged violations of regulatory requirements. We maintain various policies of insurance that, subject to limitations, exclusions, or deductibles, provide coverage for these types of claims. While we believe the amount of insurance is appropriate for our type of business, such insurance may not be adequate, in scope or amount, in the event of a major loss, and we may be exposed to uninsured liabilities that could have a material adverse effect on our consolidated financial condition, results of operations or cash flows. We may choose not to continue to maintain the insurance should market conditions in the insurance industry make such coverage cost prohibitive.

Accruals for deductibles are based on claims filed and actuarial estimates of claims development and claims incurred but not reported. Due to the variable condition of the insurance market, we have experienced, and may experience in the future, increased deductible retention levels and increased premiums or unavailability of insurance. As we assume more risk through higher retention levels, we may experience more variability in our insurance reserves and expense.

In the normal course of business, we also purchase surety bonds, insurance policies, letters of credit, or marketable securities deposits in connection with, among other things, municipal residential collection contracts, financial assurance for closure and post-closure of landfills, environmental remediation, environmental permits and business licenses and permits as a financial guarantee of our performance.

ITEM 1A. RISK FACTORS

Disclosure Regarding Forward-Looking Statements

This Annual Report on Form 10-K contains certain forward-looking information about us that is intended to be covered by the safe harbor for “forward-looking statements” provided by the Private Securities Litigation Reform Act of 1995. Forward-looking statements are statements that are not historical facts. Words such as “guidance,” “expect,” “will,” “may,” “anticipate,” “plan,” “estimate,” “project,” “intend,” “should,” “can,” “likely,” “could,” “outlook” and similar expressions are intended to identify forward-looking statements. Among other sections of this Form 10-K, the Business, Risk Factors and Management’s Discussion and Analysis of Financial Condition and Results of Operations include forward-looking statements. These statements include statements about our plans, strategies and prospects. Forward-looking statements are not guarantees of performance. These statements are based upon the current beliefs and expectations of our management and are subject to risks and uncertainties that could cause actual results to differ materially from those expressed in, or implied or projected by, the forward-looking information and statements. Although we believe that the expectations reflected in the forward-looking statements are reasonable, such expectations may not prove to be correct. Among the factors that could cause actual results to differ materially from the expectations expressed in the forward-looking statements are:

•general economic and market conditions, including inflation and changes in fuel costs, interest rates, tariffs and international trade restrictions, labor, health insurance and other variable costs that generally are not within our control, and our exposure to credit and counterparty risk;

•fluctuations in prices and demand for recycled commodities that we sell to customers;

•whether our estimates and assumptions concerning critical accounting issues are correct or appropriate, including estimates and assumptions concerning selected balance sheet accounts, income tax accounts, final capping, closure, post-closure and remediation costs, available airspace, projected costs and expenses related to our landfills and property and equipment, fair values of acquired assets and liabilities assumed in our acquisitions and labor, fuel rates and economic and inflationary trends;

•competition and demand for services in the environmental services industry;

•our ability to increase prices to our customers, which may not be adequate to offset the impact of increased costs, including labor, third-party disposal and fuel and may cause us to lose volume;

•our ability to manage growth and execute our growth strategy;

•our compliance with, and future changes in, environmental and flow control regulations and our ability to obtain approvals from regulatory agencies in connection with operating and expanding our landfills and other facilities;

•the impact on us of our substantial indebtedness, including on our ability to obtain financing on acceptable terms to finance our operations and growth strategy and to operate within the limitations imposed by financing arrangements;

•our ability to retain our investment grade ratings for our debt;

•our dependence on key personnel;

•our dependence on large, long-term collection, transfer and disposal contracts;

•the capital intensive nature of our business, which may consume cash in excess of cash flow from operations;

•exposure to liabilities or losses, to the extent not adequately covered by insurance, which could result in substantial expenses;

•risks associated with undisclosed liabilities of acquired businesses;

19

TableofContents

•risks associated with pending and future legal proceedings, including litigation, audits or investigations brought by or before any governmental body;

•severe weather conditions, including those brought about by climate change, which could impair our financial results by causing increased costs, loss of revenue, reduced operational efficiency or disruptions to our operations;

•compliance with existing and future legal and regulatory requirements, including changes relating to per- and polyfluoroalkyl substances (commonly referred to as PFAS) and other chemicals of emerging concern and limitations or bans on disposal of certain types of wastes or on the transportation of waste, which could limit our ability to conduct or grow our business, increase our costs to operate or require additional capital expenditures;

•our ability to achieve reduction in our greenhouse gas emissions and our other sustainability goals;

•safety and operational risks, including the risk of personal injury to our employees or third parties;

•potential increases in our costs if we are required to provide additional funding to any multiemployer pension plan to which we contribute or if a withdrawal event (including our voluntary withdrawal, which we consider from time to time, or the mass withdrawal of all contributing employers from any underfunded multiemployer pension plan) occurs with respect to any such plan;

•the negative impact on our operations of union organizing campaigns, work stoppages or labor shortages;

•the negative effect on our revenues that trends toward requiring recycling, waste reduction at the source and prohibiting the disposal of certain types of wastes could have on volumes of waste going to landfills;

•changes to generally accepted accounting principles or policies;

•the impact of United States and international tax laws and regulations on our business;

•risks related to interruptions and breaches of our information technology systems that could adversely affect, or temporarily disable, all or a portion of our operations or have a negative effect on our infrastructure;

•the negative impact that a significant cyber-security incident could have on our business and our relationships with our employees, customers and vendors; and

•acts of war, riots or terrorism, including the continuing war on terrorism, as well as actions taken or to be taken by the United States or other governments as a result of further acts or threats of terrorism and the impact of these acts on economic, financial and social conditions in the United States.

The risks identified in the bullet points above are not exhaustive. Refer to the Risk Factors below in this Item 1A for further discussion regarding our exposure to risks. Any forward-looking statement in this Annual Report on Form 10-K and the documents incorporated herein by reference or elsewhere, speaks only as of the date on which we make it. Additionally, new risk factors emerge from time to time and it is not possible for us to predict all such risk factors, or to assess the impact such risk factors might have on our business or the extent to which any factor or combination of factors may cause actual results to differ materially from those contained in any forward-looking statements. You should not place undue reliance on any forward-looking statement. Except to the extent required by applicable law or regulation, we undertake no obligation to update or publish revised forward-looking statements to reflect events or circumstances after the date of this Annual Report on Form 10-K and the documents incorporated by reference, as the case may be, or to reflect the occurrence of unanticipated events.

Risks Related to Our Business and Operations

The environmental services industry is highly competitive and includes competitors that may have greater financial and operational resources, flexibility to reduce prices or other competitive advantages that could make it difficult for us to compete effectively.

We principally compete with large national waste management companies, numerous municipalities and numerous regional and local companies. Competition for collection accounts is typically based on the quality of services, ease of doing business and/or price. Competition for disposal business is primarily based on geographic location, quality of operations and price. Certain competitors may have greater financial and operational resources than we do. Further, many counties and municipalities that operate their own collection and disposal facilities have the benefits of tax revenue and greater opportunities for tax-exempt financing. Our ability to obtain solid waste volume for our landfills also may be limited by the fact that some major collection operations also own or operate landfills to which they send their waste. In certain markets in which we do not own or operate a landfill, our collection operations may have difficulty competing effectively. We are also subject to risks associated with contracts awarded by municipalities and other entities through competitive bidding. For example, we may not be the successful bidder, we may need to lower our price in order to win or retain a contract, and our competitors may have lower financial expectations that permit them to reduce their prices in order to win a contract. If we were to lose market share or if we were to

20

TableofContents

lower prices to address competitive issues, it could negatively impact our consolidated financial condition, results of operations and cash flows.

Increases in the cost of fuel or petrochemicals increase our operating expenses, and we may not be able to recover such cost increases from our customers.

We depend on fuel purchased in the open market to operate our collection and transfer trucks and other equipment used for collection, transfer, disposal and other environmental services. Fuel prices are unpredictable and fluctuate significantly based on events beyond our control, including geopolitical developments, actions by the Organization of the Petroleum Exporting Countries and other oil and gas producers, changes in refinery operations, supply and demand for oil and gas, war, terrorism and unrest in oil-producing countries, adverse weather and regional production patterns. Due to contractual or market factors, we may not be able to offset increased fuel costs resulting from such volatility through fuel recovery fees. Our fuel costs were $466 million in 2025, or 2.8% of revenue, compared to $470 million in 2024, or 2.9% of revenue.

At current consumption levels, a twenty-cent per gallon change in the price of diesel fuel changes our fuel costs by approximately $26 million on an annual basis. Offsetting these changes in fuel expense would be changes in our fuel recovery fee charged to our customers. At current participation rates, we believe a twenty-cent per gallon change in the price of diesel fuel changes our fuel recovery fee by approximately $42 million. A substantial rise or drop in fuel costs could materially affect our revenue and cost of operations.

Over the last decade, regulations have been adopted mandating changes in the composition of fuels for motor vehicles. The renewable fuel standards that the EPA sets annually affect the type of fuel our motor vehicle fleet uses. It is difficult to predict the quantity of renewable fuel volumes that the EPA will mandate for future years. These regulations are one of many factors that may affect the cost of the fuel we use.

Part of our fleet of vehicles is powered by CNG and we also operate CNG fueling stations. We have invested significant upfront capital costs to purchase and support our CNG vehicles and fueling stations in order to reduce our overall fleet operating costs through lower fuel expenses and to create a competitive advantage in communities that focus on protecting the environment. CNG is not yet widely adopted in North America. As the CNG industry develops, new regulations, the availability of alternative fuel technologies, fluctuations in the price or availability of CNG or reductions in tax incentives for the use of CNG vehicles could substantially affect our revenue and costs of operations and reduce the benefits sought by investing in CNG vehicles and fueling stations.

Our operations also require the use of products (such as liners at our landfills) whose costs may vary with the price of petrochemicals. An increase in the price of petrochemicals could increase the cost of those products, which would increase our operating and capital costs. Petrochemical prices, and hence our operating and capital costs, may be further affected by regulatory efforts to reduce greenhouse gases from the industries that produce such petrochemicals. We are also susceptible to increases in fuel recovery fees from our vendors.

Fluctuations in prices and demand for recycled commodities that we sell to customers may adversely affect our consolidated financial condition, results of operations and cash flows.

We purchase or collect and process recyclable materials such as paper, cardboard, plastics, aluminum and other metals for sale to third parties. Our results of operations may be affected by changing prices or market requirements for recyclable materials. The resale and purchase prices of, and market demand for, recyclable materials are volatile due to changes in economic conditions and numerous other factors beyond our control. For instance, several states have passed legislation commonly referred to as Extended Producer Responsibility. These laws are intended to shift the cost of recycling from consumers to producers while also mandating increased supply, which could lead to lower commodity prices. Significant price fluctuations or increased operating costs may affect our consolidated financial condition, results of operations and cash flows.

At current volumes and mix of materials, we believe a $10 per ton change in the price of recycled commodities change both annual revenue and operating income by approximately $13 million. Accordingly, a substantial rise or drop in recycled commodity prices could materially affect our revenue and operating income. Although we have entered into hedging agreements to help offset volatility in recycled commodity prices in the past, we do not have any such hedging agreements currently, and we may not enter into these agreements in the future.

Acute and chronic weather events, including those brought about by climate change, may adversely impact our operations and increase the costs of collection, transfer, disposal and other environmental services we provide.

Our operations could be adversely impacted by extreme weather events, changing weather patterns and rising mean temperature and sea levels, some of which we are already experiencing. For example, we have operations in multiple states that are affected by hurricanes and/or wildfires, and we have seen the impact of storms and associated flooding or other damage in our day-to-day operations and to our infrastructure. Changing weather patterns and rising temperatures are expected to result in more

21

TableofContents

severe heat waves, fires, storms and other extreme weather events. Any of these factors could increase the volume of material collected or processed under our existing contracts (without corresponding compensation), impede our employees' and equipment's ability to operate, result in asset impairment, disrupt our supply chain, delay the development of landfill capacity, or reduce the volume of material generated by our customers. In addition, while we have business continuity plans in place for severe weather, natural disasters and other emergencies, these events may result in the temporary suspension of our operations, which can significantly affect our operating results in the affected regions during those periods.

The environmental services industry is capital-intensive and our capital expenditures may exceed current expectations, which could require us to obtain additional funding for our operations or impair our ability to grow our business.

Our ability to remain competitive and to grow our business largely depends on our cash flow from operations and access to capital. If our capital efficiency programs cannot offset the effect of inflation and business growth, it may be necessary to increase the amount we spend. Additionally, as we make acquisitions and further expand our operations, the amount we spend on capital, capping, closure, post-closure, environmental remediation and other items will increase. Our cash needs also will increase if the expenditures for capping, closure, post-closure and remediation activities increase above our current estimates, which may occur over a long period due to changes in federal, state, provincial, or local government requirements and other factors beyond our control. Increases in expenditures would negatively impact our cash flows.

We may be unable to obtain or maintain required permits or to expand existing permitted capacity of our facilities, which could decrease our revenue and increase our costs.

We cannot assure you that we will be able to obtain or maintain the permits required for our operations because permits to operate new landfills, transfer stations and other facilities, or to expand the permitted capacity of existing landfills, increase acceptable volume at transfer stations or otherwise increase the capabilities of our facilities, have become more difficult and expensive to obtain and maintain. Permits often take years to obtain as a result of numerous hearings and compliance requirements with regard to zoning, environmental and other regulations. Local communities and citizen groups, adjacent landowners, governmental agencies and others have in the past opposed and may in the future oppose the issuance of a permit or approval we may need, allege violations of the permits under which we currently operate or laws or regulations to which we are subject, or seek to impose liability on us for environmental damage. Such actions could also create risks related to our reputation, which may limit our ability to do business. Responding to these challenges has, at times, increased our costs and extended the time associated with establishing new landfills, transfer stations and other facilities and expanding existing facilities. In addition, failure to receive regulatory and zoning approval may prohibit us from establishing new landfills, transfer stations and other facilities, or expanding existing facilities. Our failure to obtain the required permits to operate our landfills, transfer stations and other facilities could have a material adverse effect on our consolidated financial condition, results of operations and cash flows. In addition, we may have to transport and dispose collected waste at facilities operated by our competitors or haul the waste long distances at a higher cost to one of our other facilities, either of which could significantly increase our waste transportation and disposal costs.

If we do not appropriately estimate landfill capping, closure, post-closure and remediation costs, our consolidated financial condition and results of operations may be adversely affected.

A landfill must be closed and capped, and post-closure maintenance commenced, once the landfill's permitted capacity is reached and additional capacity is not authorized. Further, we undertake remediation activities at some of our solid waste facilities. We have significant financial obligations relating to capping, closure, post-closure and remediation costs at our existing owned or operated landfills, and will have material financial obligations with respect to any future owned or operated landfills. We establish accruals for the estimated costs associated with capping, closure, post-closure and remediation obligations. We could underestimate such costs and our financial obligations for capping, closure, post-closure or remediation costs could exceed the amounts accrued or amounts otherwise receivable pursuant to trust funds established for this purpose. Additionally, if a landfill must be closed earlier than expected or its remaining airspace is reduced for any other reason, the accruals for capping, closure, post-closure and remediation could be required to be accelerated. If our capping, closure, post-closure or remediation costs exceed the amounts accrued, or if such accruals are required to be accelerated, this could have a material adverse effect on our consolidated financial condition, results of operations and cash flows.

Alternatives to landfill disposal, and increasing customer preferences for these alternatives, could reduce our disposal volumes and cause our revenues and operating results to decline.

Most of the states in which we operate landfills require counties and municipalities to formulate comprehensive plans to reduce the volume of solid waste deposited in landfills through waste planning, composting, recycling or other programs. Some state and local governments mandate waste reduction at the source and prohibit the disposal of certain types of wastes, such as yard waste, at landfills. Further, many of our customers voluntarily are diverting waste to alternatives to landfill disposal, such as recycling and composting, while also working to reduce the amount of waste they generate. Many of the largest companies in

22

TableofContents

the United States are setting zero-waste goals in which they strive to send no waste to landfills and some jurisdictions have enacted or are considering waste reduction regulations such as extended producer responsibility, organic diversion and minimum recycled content regulations. Although such actions help to protect our environment and reduce the impact of waste on climate change, they have reduced, and will in the future reduce, the volume of waste going to landfills and may affect the prices that we can charge for landfill disposal. Accordingly, we may not be able to operate our landfills at their current volumes or charge current prices for landfill disposal services due to possible decreases in demand for such services. If we cannot expand our service offerings and grow lines of business to service waste streams that do not go to landfills and to provide services for customers that wish to reduce waste entirely, this could have a negative effect on our consolidated financial condition, results of operations and cash flows. Further, even if we can develop such service offerings and lines of business, disposal alternatives nonetheless could negatively affect our consolidated financial condition, results of operations and cash flows.

We could incur charges to income, which could be material, if landfill and transfer station site development projects or expansion projects are not completed, or certain other events occur.

In accordance with the accounting principles generally accepted in the United States of America (U.S. GAAP), we capitalize certain expenditures relating to the development and expansion of landfills, transfer stations and other projects. If a facility or operation is permanently shut down or determined to be impaired, or a development, expansion or other project is not completed or is determined to be impaired, we will charge against earnings any unamortized capitalized expenditures relating to such facility or project that we are unable to recover through sale, transfer or otherwise. We also carry a significant amount of goodwill on our consolidated balance sheets, which we must assess for impairment annually, and more frequently in the case of certain triggering events. We may incur charges against earnings in accordance with this policy, or other events may cause impairments. Such charges could have a material adverse effect on our results of operations.

The business and assets we operate expose us to safety, operational and other risks, including the risk of personal injury to our employees or third parties.

The provision of environmental services, including the operation of our facilities, a substantial fleet of trucks and other environmental services-related assets, involves risks. These risks include, among others, the risk of truck accidents, equipment defects, malfunctions and failures, improper use of dangerous equipment, the release of hazardous substances, fire and explosion, any of which could result in environmental liability, personal injury, loss of life, business interruption or property damage or destruction. While we carry insurance to cover many contingencies, and seek to minimize our exposure to these risks through maintenance, training and compliance programs, any substantial losses could have a material adverse effect on our business, results of operations and financial condition.

We are periodically subject to work stoppages and other workforce effects, which increases our operating costs and disrupts our operations.

As of December 31, 2025, approximately 22% of our workforce was covered by collective bargaining agreements. We have experienced interrupted service when our union-represented employees have engaged in strikes and work stoppages in the past, including in 2025, and we would expect the same to occur as a result of any future strikes or work stoppages. When our union-represented employees engage in strikes, work stoppages or other slowdowns, we typically experience disruptions of our operations and increases in our operating costs, which may be significant, and which may have an adverse effect on our consolidated financial condition, results of operations and cash flows. Additional groups of employees may seek union representation in the future which could result in further increased operating costs. If a greater percentage of our workforce becomes union-represented, our consolidated financial condition, results of operations and cash flows could be adversely impacted due to the potential for increased operating costs.

We may not be able to achieve reduction of our greenhouse gas emissions and our other sustainability goals.

Climate change and other sustainability matters are embedded in our core value and vision. As part of our strategic long-term plans to address sustainability, among other sustainability goals, we are committed to reducing our absolute Scope 1 and Scope 2 greenhouse gas emissions 35% by 2030 relative to the 2017 baseline year. The execution of our plans and achievement of our goals are subject to risks and uncertainties, including our ability to develop, obtain, license or scale the innovations, technologies and modeling and measurement tools that may be necessary to achieve our plans and the availability, cost and benefits of materials and infrastructure associated with our sustainability projects, such as our CNG vehicles, fleet electrification, recycling, circularity of key materials, landfill gas-to-energy, solar and other renewable energy projects.

In addition, increasing governmental and societal attention to sustainability matters, including expanding mandatory and voluntary reporting in certain jurisdictions, diligence and disclosure on topics such as climate change, waste production, water usage, talent management and risk oversight, could expand the nature, scope and complexity of matters that we are required to control, assess and report. These and other rapidly changing laws, regulations, policies and related interpretations, as well as

TableofContents

increased enforcement actions by various governmental and regulatory agencies, create challenges for us. If we are unable to continue to meet these challenges and comply with all laws, regulations, policies and related interpretations, and meet the sustainability values, standards and metrics that we set for ourselves, it could negatively impact our reputation and our business results.

Risks Related to our Legal and Regulatory Environment

We are subject to costly environmental and flow-control regulations and requirements that may affect our operating margins, restrict our operations and subject us to additional liability.

Complying with laws and regulations governing the collection, treatment, storage, transfer and disposal of material, air quality and emissions of greenhouse gases, water quality and the remediation of contamination associated with the release of hazardous substances is costly. Laws and regulations often require us to, among other things, enhance or replace our equipment and to modify landfill operations or initiate final closure of a landfill. We may not be able to implement price increases sufficient to offset the costs of complying with these laws and regulations. In addition, environmental regulatory changes, including those relating to PFAS and other chemicals of emerging concern, could accelerate or increase expenditures for capping, closure, post-closure and environmental and remediation activities at our waste facilities and obligate us to spend sums in addition to those accrued for such purposes, which could have a negative effect on our consolidated financial position, results of operations and cash flows. For example, the EPA in 2024 listed two PFAS as hazardous substances under CERCLA, and has indicated it is considering listing additional PFAS as hazardous substances under CERCLA, which could trigger additional obligations or liabilities under CERCLA or other laws and regulations. Further, under certain municipal and other agreements, we are subject to landfill diversion requirements that if not met, subject us to liquidated damages and other costs and expenses, the result of which could adversely affect our business, reputation and operating margins.

Our environmental solutions operations and facilities also are subject to Canadian environmental laws and regulations, including federal and provincial regulations governing the management of hazardous waste, as well as various treaties, laws and regulations governing the ownership, operation and maintenance of maritime vessels used in the business.Our environmental solutions operations are also subject to federal statutes regulating the treatment, storage and disposal of certain radioactive materials.

Our business is and will continue to be affected by state, county, provincial, or local laws or regulations that restrict the transportation of solid waste across state, county, provincial, or other jurisdictional lines or that direct the flow of waste to a specified facility or facilities. Such laws and regulations could negatively affect our operations, resulting in declines in landfill volumes and increased costs of alternate disposal.

Regulation of greenhouse gas emissions and other governmental regulations could impose costs on our operations, the magnitude of which is difficult to estimate.

Efforts to curtail the emission of greenhouse gases and to ameliorate the effects of climate change continue to progress. Our landfill operations emit anthropogenic methane, identified as a greenhouse gas, and our vehicle fleet emits, among other things, carbon dioxide, which also is a greenhouse gas. While passage of comprehensive, federal climate change legislation appears unlikely in the near term, we expect any such legislation, if enacted, to impose costs on our operations, which could be material.

Absent comprehensive federal legislation to control greenhouse gas emissions, the EPA has taken certain actions administratively under its existing Clean Air Act authority. The EPA is compelled to issue rules by the United States Supreme Court's April 2007 Massachusetts v. EPA ruling that greenhouse gases are pollutants for purposes of the Clean Air Act and the EPA's December 2009 finding that continued emissions of greenhouse gases endanger human health and welfare. With respect to our light- and heavy-duty vehicle fleet, the EPA has issued regulations limiting greenhouse gas emissions and increasing fuel economy standards. The EPA and the NHTSA periodically issue additional regulations covering additional model years of vehicles, typically increasing the stringency of the relevant vehicle standards, and those rules are frequently challenged in court. For further discussion, see Item 1. Business – Regulation – Federal Regulation – The Clean Air Act, in this Annual Report on Form 10-K. These standards and further federal efforts to curtail greenhouse gas emissions and to increase the fuel efficiency of light-duty and heavy-duty vehicles could have a material adverse effect on our consolidated financial condition, results of operations and cash flows.

With regard to greenhouse gas emissions from our landfills, on July 14, 2016, the EPA issued amendments to its regulations that require large landfills that commenced construction, reconstruction or modification on or after July 17, 2014 to capture additional landfill gas to reduce emissions of methane and certain non-methane gases, which are recognized as greenhouse gases. In a separate action finalized that same day, the EPA issued updates to its 1996 Emission Guidelines to reduce emissions of landfill gas from existing active landfills. The EPA has taken further steps to implement these regulations. These regulations, or an amended version of them that eventually goes into effect, may require our landfills to deploy more stringent emission controls and monitoring systems, with resulting capital or operating costs. The application of these or other greenhouse gas

regulations to our landfills could have a material adverse effect on our landfill operations and on our consolidated financial condition, results of operations and cash flows. We cannot predict what other actions or regulations the current administration may undertake that would affect our industry.

At the U.S. state level, California has taken action to require greenhouse gas emission disclosure, as well as information on climate-related financial risks, some of which are subject to legal challenge. Similar bills have been introduced in other U.S. states; to-date, none have passed into law.

In Canada, the federal Greenhouse Gas Pollution Pricing Act imposes a carbon pricing system for industry in provinces and territories that have not implemented carbon pricing systems of their own or, in the opinion of the federal government, have implemented carbon pricing systems that do not align with the federal benchmark requirements. This federal system imposed a carbon levy to the sale of fuel (fuel charge) and sets out an output-based pricing system that applies to industrial emitters that meet certain criteria set out in the statute and its regulations, which creates a price incentive for industrial emitters to reduce greenhouse gas emissions by establishing a regulatory trading system for industry. In April 2025, the Canadian federal government effectively eliminated the fuel charge but the output-based pricing system remains. Additionally, the Canadian federal government finalized new Landfill Methane Regulations in December 2025, which are intended to reduce waste sector methane emissions by 42% below 2019 levels by 2030. Both direct and indirect costs associated with compliance with this and other greenhouse gas legislation could have a material adverse effect on our consolidated financial condition, results of operations and cash flows, including material increases to our capital or operating costs related to matters such as infrastructure upgrades or increased fuel costs.

We may incur losses from liabilities that are not covered by our insurance. Changes in insurance markets also may impact our financial results.

We may incur liabilities or suffer losses arising from our operations or properties that resulted in harm to the environment, property, employees or the general public. We maintain insurance for these liabilities and losses, including high deductibles for our environmental liability insurance coverage. If we were to incur substantial liability or loss in connection with these contingencies, our insurance coverage may be inadequate to cover such liability or loss. This could have a material adverse effect on our consolidated financial condition, results of operations and cash flows.

Also, due to the variable condition of the insurance market, we have experienced, and may experience in the future, increased insurance retention levels and increased premiums or unavailability of insurance. As we assume more risk for insurance through higher retention levels, we may experience more variability in our insurance reserves and expense.

Despite our efforts, we may incur additional liability under environmental laws in excess of amounts presently known and accrued.

We are a potentially responsible party at many sites under CERCLA, which provides for the remediation of contaminated facilities and imposes strict, joint and several liability for the cost of remediation on current owners and operators of a facility at which there has been a release or a threatened release of a hazardous substance. CERCLA liability also extends to parties who were site owners and operators at the time hazardous substances were disposed and to persons who arrange for the disposal of such substances at the facility (e.g., generators of the waste and transporters who selected the disposal site). Hundreds of substances are defined as hazardous under CERCLA and their presence, even in minute amounts, can result in substantial liability.

Notwithstanding our efforts to comply with applicable environmental laws, we may have additional liability under environmental laws in excess of our current reserves because, among other things, hazardous substances may be present in waste collected by us or disposed of in our landfills (or in waste collected, transported or disposed of in the past by businesses we have acquired), environmental laws or regulations may change, or there may be adverse environmental conditions that develop or were otherwise previously unknown to us. Environmental liabilities in excess of our current reserves could have a material adverse effect on our consolidated financial position, results of operations and cash flows.

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

We are and will continue to be involved in lawsuits, regulatory inquiries and governmental and other legal proceedings. Many of these matters raise complicated factual and legal issues and are subject to uncertainties. The timing of the final resolutions to lawsuits, regulatory inquiries and governmental and other legal proceedings is uncertain. Further, the possible outcomes or resolutions to these matters could include adverse judgments, fines or settlements, any of which could require substantial payments and adversely affect our consolidated financial condition, results of operations and cash flows.

25

TableofContents

For example, we incur costs to defend against litigation brought by government agencies and private parties who allege we are in violation of our permits and applicable environmental laws and regulations, or who assert claims alleging nuisance, environmental damage, personal injury or property damage. As a result, we have in the past been required and may in the future be required to pay fines or judgments or implement corrective measures, or we may have our permits and licenses modified or revoked. A significant judgment against us or settlement, the loss of a significant permit or license, or the imposition of a significant fine could have a material adverse effect on our consolidated financial condition, results of operations and cash flows. We establish accruals for our estimates of the costs associated with lawsuits, regulatory, governmental and other legal proceedings. We could underestimate such accruals. Such shortfalls could result in significant unanticipated charges to income.

Changesto federal renewable fuel policies could affect our financial performance in that sector as a renewable fuel producer and impact our projected future investments.

We are engaged in 84 landfill gas-to-energy and other renewable energy projects. The production of renewable fuel through certain of these projects is incentivized by the federal Renewable Fuel Standard (RFS) program. Oil refiners and importers are required through the RFS program to blend specified volumes of renewable transportation fuels with gasoline or buy RINs from renewable fuel producers. RIN prices generally respond to administrative actions, decisions and/or regulations from the EPA, including the issuance of an annual renewable volumetric obligation, as well as fluctuations in supply and demand. Changes in the RFS market, the structure of the RFS program or RIN prices and demand may impact the financial performance of the projects developed to capture and treat gas and could impact or alter our projected future investments.

Risks Related to Financial Strategy and Indebtedness

We have substantial indebtedness, which may limit our financial flexibility.

As of December 31, 2025, we had approximately $14 billion in principal value of debt and finance leases outstanding. This amount of indebtedness and our debt service requirements may limit our financial flexibility to access additional capital and make capital expenditures and other investments in our business, to withstand economic downturns and interest rate increases, to plan for or react to changes in our business and our industry and to comply with the financial and other covenants of our debt instruments. Further, our ability to comply with these financial and other covenants may be affected by changes in economic or business conditions or other events that are beyond our control. If we do not comply with these covenants, we may be required to take actions such as reducing or delaying capital expenditures, reducing or eliminating dividends or stock repurchases, selling assets, restructuring or refinancing all or part of our existing debt, or seeking additional equity capital.

We may be unable to maintain our credit ratings or execute our financial strategy.

Our ability to execute our financial strategy depends in part on our ability to maintain investment grade ratings on our debt. Our credit ratings depend on a number of factors, many of which are beyond our control, and we may not be able to maintain our investment grade ratings. If we are unable to do so, our interest expense would increase and our ability to obtain financing on favorable terms may be adversely affected.

Our financial strategy also depends on our ability to generate sufficient cash flow to reinvest in our existing business, fund internal growth, acquire other environmental services businesses, pay dividends, repurchase stock and take other actions to enhance shareholder value. We may not succeed in executing our broad-based pricing initiatives, and we may not generate sufficient cash flow to execute our financial strategy, pay cash dividends at our present rate, or increase them, or be able to continue our share repurchase program.

Weakness in the United States economy may expose us to credit risk for amounts due from governmental entities, large national accounts, industrial customers and others.

Weakness in the United States economy can reduce the amount of taxes collected by various governmental entities. We provide services to a number of these entities, including numerous municipalities. These governmental entities may suffer financial difficulties resulting from a decrease in tax revenue and may ultimately be unable or unwilling to pay amounts owed to us. In addition, weakness in the economy may cause other customers, including our large national accounts, or industrial or other environmental services clients, to suffer financial difficulties and ultimately to be unable or unwilling to pay amounts owed to us. This could negatively impact our consolidated financial condition, results of operations and cash flows.

Our consolidated financial statements are based on estimates and assumptions that may differ from actual results.The liabilities we record based on such estimates and assumptions may not be adequate to cover the costs we ultimately will face.

Our consolidated financial statements have been prepared in accordance with U.S. GAAP and necessarily include amounts based on management's estimates. Actual results may differ from these amounts. Significant items requiring management to make subjective or complex judgments that are inherently uncertain include the recoverability of long-lived assets, the depletion

and amortization of landfill development costs, accruals for final capping, closure and post-closure costs, valuation allowances for accounts receivable and deferred tax assets, liabilities for potential litigation, claims and assessments and liabilities for environmental remediation, multiemployer pension plans, employee benefit plans, deferred taxes, uncertain tax positions, insurance and our estimates of the fair values of assets acquired and liabilities assumed in any acquisition. The liabilities recorded for items such as these may not be adequate to cover the costs we ultimately will face.

Our obligation to fund multiemployer pension plans to which we contribute, or our withdrawal from such plans, may have an adverse effect on us.

We participate in multiemployer pension plans that generally provide retirement benefits to participants of contributing employers. We do not administer these plans and generally are not represented on the boards of trustees of these plans. The Pension Protection Act enacted in 2006 (the PPA) requires under-funded pension plans to improve their funding ratios. Based on the information available to us, we believe that some of the multiemployer plans to which we contribute are either critical or endangered as those terms are defined in the PPA. We cannot presently determine the amount of additional funding, if any, we may be required to make to these plans. However, plan assessments could have a material adverse effect on our results of operations or cash flows for a given period.

Further, under current law, upon the termination of a multiemployer pension plan, or in the event of a withdrawal by us (which we consider from time to time) or a mass withdrawal of contributing employers (each, a Withdrawal Event), we would be required to make payments to the plan for our proportionate share of the plan's unfunded vested liabilities. We cannot assure you that there will not be a Withdrawal Event with respect to any of the multiemployer pension plans to which we contribute or that, in the event of such a Withdrawal Event, the amounts we would be required to contribute would not have a material adverse effect on our consolidated financial condition, results of operations and cash flows.

For additional discussion and detail regarding multiemployer pension plans see Note 12, Employee Benefit Plans, of the notes to our audited consolidated financial statements in Part II, Item 8 of this Annual Report on Form 10-K.

Risks Related to Our Growth Strategy

We may be unable to manage our growth effectively.

Our growth strategy places significant demands on our financial, operational and management resources. To continue our growth, we may need to add administrative, managerial and other personnel, and may need to make additional investments in operations and systems. We may not be able to find and train qualified personnel, or do so on a timely basis, or to expand or otherwise modify our operations and systems to the extent, and in the time, required.

We may be unable to execute our acquisition growth strategy.

Our ability to execute our growth strategy depends in part on our ability to identify and acquire desirable acquisition candidates and on our ability to successfully integrate acquired operations into our business. The integration of our operations with those of acquired companies may present significant challenges to our management. In addition, competition for acquisition candidates may prevent us from acquiring certain acquisition candidates. Thus, we cannot assure you that:

•desirable acquisition candidates exist or will be identified;

•we will be able to acquire any of the candidates identified;

•we will effectively integrate and manage companies we acquire; or

•any acquisitions will be profitable or accretive to our earnings.

If any of these factors force us to alter our growth strategy, our growth prospects could be adversely affected.

Businesses we acquire may have undisclosed liabilities.

Our due diligence investigations of acquisition candidates may fail to discover certain undisclosed liabilities. If we acquire a company with undisclosed liabilities such as environmental, remediation or contractual liabilities, as a successor owner we may be responsible for such undisclosed liabilities. We try to minimize our exposure to such liabilities by conducting due diligence, by obtaining indemnification from each seller of the acquired companies, by deferring payment of a portion of the purchase price as security for the indemnification, by obtaining representations and warranties insurance and by acquiring only specified assets. However, we may not be able to obtain indemnification, insurance coverage or other security, and such indemnification, insurance coverage or other security obtained may not be enforceable, collectible or sufficient in amount, scope or duration to fully offset any undisclosed liabilities arising from our acquisitions.

Risks Related to Technology and Intellectual Property

Our strategy includes an increasing dependence on technology, including the use of artificial intelligence (AI), in our operations. If any of our key technology fails, our business could be adversely affected.

Our operations are increasingly dependent on technology, including AI and machine learning tools that we deploy or that are embedded in systems provided by third parties. Our information technology systems are critical to our ability to drive profitable growth through differentiation, continue the implementation of standardized processes and deliver a consistent customer experience. One of our three differentiating capabilities is to enable our customers to do business with us through more channels and with better access to information and, accordingly, we have made substantial investment in our e-commerce platform. Problems with the operation of the information or communication technology systems we use could adversely affect, or temporarily disable, all or a portion of our operations. Inabilities and delays in implementing new systems can also affect our ability to realize projected or expected revenue or cost savings. AI models and tools can produce inaccurate, biased, or inconsistent outputs and may rely on third-party content or training data for which we do not have sufficient rights. Further, any systems failures could impede our ability to timely collect and report financial results in accordance with applicable laws.

Emerging technologies, including those that are used to recycle and process waste as an alternative to disposal of waste in landfills, represent risks, as well as opportunities, to our current business model. The costs associated with developing or investing in emerging technologies, particularly data-intensive and compute-intensive AI applications, could require substantial capital and adversely affect our results of operations and cash flows. Delays in the development or implementation of such emerging technologies and difficulties in marketing new products or services based on emerging technologies could have similar negative impacts. Our financial results may suffer if we are not able to develop or license emerging technologies, or if a competitor obtains exclusive rights to an emerging technology that disrupts the current methods used in the environmental services industry.

A significant cybersecurity incident could negatively impact our business and our relationships with employees, customers and vendors and expose us to increased liability.
