SiteOne Landscape Supply, Inc. (SITE) Business

Item 1. Business

The following discussion of our business contains “forward-looking statements,” as discussed in “Special Note Regarding Forward-Looking Statements and Information” above. Our business, operations, and financial condition are subject to various risks as set forth in Part I, Item 1A., ‘‘Risk Factors’’ below. The following information should be read in conjunction with the Risk Factors, Management’s Discussion and Analysis of Financial Condition and Results of Operations, and the Financial Statements and Supplementary Data and related notes included elsewhere in this Annual Report on Form 10-K.

Company Overview

We are the largest and only national full product line wholesale distributor of landscape supplies in the United States and have an established presence in Canada. Our customers are primarily residential and commercial landscape professionals who specialize in the design, installation, and maintenance of lawns, gardens, golf courses, and other outdoor spaces. As of December 28, 2025, we had over 670 branch locations in 45 U.S. states and five Canadian provinces. Through our expansive North American network, we offer a comprehensive selection of approximately 180,000 stock keeping units (“SKUs”) including hardscapes (such as pavers, natural stone, and blocks), irrigation supplies, fertilizer and control products (e.g., herbicides), landscape accessories, nursery goods, outdoor lighting, and ice melt products. We also provide value-added consultative services to complement our product offerings and to help our customers operate and grow their businesses. Our consultative services include assistance with irrigation project take-offs, commercial project planning, generation of sales leads, business operations, and product support services, as well as a series of technical and business management seminars that we call SiteOne University.

Our typical customer is a private landscape contractor that operates in a single market. We interact regularly with our customers because of the recurring nature of landscape services and because most contractors buy products on an as-needed basis. We believe our high-touch customer service model strengthens relationships, builds loyalty, and drives repeat business. In addition, our broad product portfolio, convenient branch locations, and nationwide fleet of over 2,600 delivery vehicles position us well to meet the needs of our customers and ensure timely delivery of products. We source our products from approximately 6,000 suppliers, including the major irrigation equipment manufacturers, turf and ornamental fertilizer and chemical companies, and a variety of suppliers who specialize in nursery goods, outdoor lighting, hardscapes, and other landscape products.

We have a balanced mix of sales across product categories, construction sectors, and end markets. Approximately 60% of our 2025 Fiscal Year Net sales were derived from the residential construction sector, 32% from the commercial construction (including institutional) sector, and 8% from the recreational and other construction sector. By end market, we derived approximately 36% of our 2025 Fiscal Year Net sales from the sale of products relating to maintenance of existing residential, commercial, and recreational properties. The recurring nature of landscape maintenance demand helps to provide stability in our financial performance across economic cycles. The sale of products relating to new construction of homes, commercial buildings and facilities, and recreational spaces accounted for approximately 34% of our 2025 Fiscal Year Net sales. Approximately 30% of our 2025 Fiscal Year Net sales were derived from sales of products for the repair and upgrade of existing landscapes. These sales benefit from increases in existing home sales and rising consumer spending.

Net Sales for the 2025 Fiscal Year

Our History

Our company was established after Deere & Company (“Deere”) entered the wholesale landscape distribution market through the acquisitions of McGinnis Farms and Century Rain Aid in 2001, United Green Mark in 2005, and LESCO Inc. (“LESCO”) in 2007, each of which significantly expanded our geographic footprint and broadened our product portfolio. In December 2013, an affiliate of Clayton, Dubilier & Rice, LLC (“CD&R”) purchased a 60% interest in our company from Deere (“CD&R Acquisition”). On May 17, 2016, we completed the initial public offering of our common stock.

Our Industry

Based on management’s estimates, we believe that our addressable market in North America for the wholesale distribution of landscape supplies represented approximately $25 billion in revenue in the 2025 Fiscal Year. Growth in our industry is driven by a broad array of factors, including consumer spending, housing starts, existing home sales, home prices, mortgage interest rates, commercial, recreational, and residential construction, repair and remodeling spending, and demographic trends. Within the wholesale landscape supply industry, products sold for residential applications represent the largest construction sector, followed by the commercial, and recreational and other sectors. Based on management estimates, we believe that nursery products represent the largest product category in the industry, with sales accounting for more than one-third of industry sales, followed by landscape accessories with approximately one-fifth of industry sales, and each of hardscapes, irrigation supplies and outdoor lighting, control products, and fertilizer and other products accounting for approximately one-tenth of industry sales.

The wholesale landscape supply industry is highly fragmented, consisting primarily of regional private businesses that typically have a small geographic footprint, a limited product offering, and limited supplier relationships. Wholesale landscape supply distributors primarily sell to landscape service firms, ranging from sole proprietorships to national enterprises. Landscape service firms include general landscape contractors and specialty landscape firms, who provide services such as lawn care, tree and foliage maintenance, and landscape design and installation services. Over the past decade, professional landscape contractors have increasingly offered additional products and services to meet their customers’ needs. These firms historically needed to make numerous trips to branches in various locations to source their products. Consequently, landscape professionals have come to value distribution partners who offer a larger variety of product categories and services, particularly given the recurring nature of landscape maintenance services.

Our Strategies

Key elements of our strategy are as follows:

Build Upon Strong Customer and Supplier Relationships to Grow Organically

Our national footprint and broad supplier relationships, combined with our regular interaction with a large and diverse customer base, make us an important link in the supply chain for landscape products. Our suppliers benefit from access to our more than 440,000 customers, a single point of contact for improved production planning and efficiency, and our ability to bring new product launches quickly to market on a national scale. We intend to keep increasing our size and scale in customer, geographic, and product reach, which we believe will continue to benefit our supplier base. We will continue to work with new and existing suppliers to maintain the most comprehensive product offerings for our customers at competitive prices and enhance our role as a critical player in the supply chain.

Grow at the Local Level

The vast majority of our customers operate at a local level. We believe we can grow market share in our existing markets with limited capital investment by systematically executing local strategies to expand our customer base, increase the amount of our customers’ total spending with us, optimize our network of locations, coordinate multi-site deliveries, partner with strategic local suppliers, introduce new products and services, increase our share of underrepresented products in particular markets, and improve sales force performance. We currently only offer our full product line in approximately 30% of the metropolitan statistical areas (“MSAs”) in the U.S. where we have a branch, and therefore believe we have the capacity to offer significantly more product lines and services in our geographic markets.

Pursue Value-Enhancing Strategic Acquisitions

Through acquisitions, we have added new markets in the U.S. and Canada, new product lines, talented associates, and operational best practices. In addition, we increased our sales by introducing products from our existing portfolio to customers of newly acquired companies. We intend to continue pursuing strategic acquisitions to better serve our customers, grow our market share, and enhance our local market leadership positions by taking advantage of our scale, operational experience, and acquisition know-how. We currently have branches in approximately 50% of the 387 U.S. MSAs and are focused on identifying attractive new geographic markets for expansion through acquisitions. We will continue to apply a selective and disciplined acquisition strategy to maximize synergies obtained from enhanced sales and lower procurement and administrative costs.

Execute on Identified Operational Initiatives

We continue to undertake operational initiatives, utilizing our scale to improve our profitability, enhance supply chain efficiency, strengthen our category management capabilities, streamline and refine our marketing process, and invest in more sophisticated information technology systems and data analytics. Additionally, we have continued to advance our digital initiative, to include the enhancement of our website and business-to-business (“B2B”) e-Commerce platform. The enhancements have increased connectivity with our customers and have resulted in better customer service as well as contributed to improvement in our profitability. We remain focused on delivering additional enhancements to our digital offering and believe we will continue to benefit from these and other operational initiatives.

Be the Employer of Choice

We believe our associates are the key drivers of our success, and we aim to recruit, train, promote, and retain the most talented and success-driven personnel in the industry. Our size and scale enable us to offer structured training and career path opportunities for our associates. We have built a vibrant and entrepreneurial culture that rewards performance at the area and branch levels. We promote ongoing, open, and honest communication with our associates, including periodic engagement surveys, to ensure mutual trust, engagement, and performance improvement. We believe that high-performing local leaders coupled with creative, adaptable, and engaged associates are critical to our success and to maintaining our competitive position, and we are committed to being the employer of choice in our industry.

Our Products and Services

Our comprehensive portfolio of landscape products consists of approximately 180,000 SKUs from approximately 6,000 suppliers. Our product portfolio includes hardscapes, irrigation supplies, fertilizer and control products, landscape accessories, nursery goods, and outdoor lighting products. Our customers value our product breadth and geographic reach, as well as our on-site expertise and consultative services. While pricing is important to our customers, availability, convenience, and expertise are also important factors in their purchase decisions. In addition to other capabilities, our ability to offer the significant yard space and special equipment required for hardscapes and nursery goods for example, provide us with a competitive advantage over many competitors who offer a more limited selection of product categories.

Refer to “Note 2. Revenue from Contracts with Customers” to our audited financial statements for information regarding our Net sales of landscaping products (hardscapes, irrigation supplies, landscape accessories, nursery goods, and outdoor lighting) and agronomic and other products (fertilizer, control products, ice melt, equipment, and other products).

Hardscapes

Our hardscapes products include pavers, natural stone, blocks, and other durable materials. The “outdoor living” trend has been a driver of demand for these products.

Irrigation Supplies

Our irrigation supplies products include among other things, sprinkler heads, irrigation pipe and tubing, controllers, valves, fittings, and micro-irrigation or drip products. The market for irrigation supplies has historically provided stable growth and is driven primarily by new home and commercial construction as well as maintenance of existing irrigation systems.

Fertilizer and Other

Our fertilizer and other products include fertilizer, grass seed, combination products (pesticides on a fertilizer carrier), and ice melt products. Fertilizer products are sold to the maintenance end market and accordingly are relatively stable through economic cycles.

Landscape Accessories

Our landscape accessories products include mulches, soil amendments, drainage pipe, tools, and sod. Landscape accessories are typically sold in combination with other landscape supply products. As a result, sales of these accessories are often tied to sales of fertilizers and control products, as well as sales of hardscapes and nursery goods.

Nursery Goods

Our nursery goods products include deciduous and evergreen shrubs, ornamental, shade, and evergreen trees, both field-grown and container-grown nursery stock, roses, perennials, annuals, bulbs, and thousands of plant species and cultivars that are available in a number of container sizes, heights, forms, and bloom colors.

Control Products

Our control products are specialty products that include herbicides, fungicides, rodenticides, and other pesticides. Similar to fertilizer products, control products sales are strongly tied to the maintenance end market and accordingly are relatively stable through economic cycles.

Outdoor Lighting

Our outdoor lighting products include lighting fixtures (path, area, accent, up, down, well, hardscape, deck, underwater, bistro, and holiday), LED lamps, wire, transformers, and accessories. Similar to hardscapes products, interest in “outdoor living” is an important driver of sales of outdoor lighting products.

Proprietary Branded Products

In addition to distributing branded products of third parties, we offer products under our proprietary brands. Sales of our proprietary branded products accounted for approximately 15% of our 2025 Fiscal Year Net sales, the large majority of which is attributable to LESCO®.

LESCO®

LESCO® is a premium brand that maintains strong brand awareness with golf and professional landscape contractors. Under the LESCO® brand, we offer formulations of fertilizer (liquid and granular), combination products (pesticides on a fertilizer carrier), control products (liquid and granular pesticides), specialty chemicals, turf seed, application equipment (engine powered and walk behind or other non-engine powered), paint, and maintenance products like engine oil, ice melt, and soil tests. LESCO® products are sold through our branches and retail outlets.

Pro-Trade®

We offer full lines of professional-grade landscape lighting and synthetic turf along with irrigation and landscape supplies, under our Pro-Trade® brand. The Pro-Trade® line of products is sold exclusively through our branches and website. During the 2025 Fiscal Year, we added weed barrier fabrics and accessories, holiday lighting, and expanded our product offerings in irrigation, tools, and other landscape accessories. We plan to continue adding to our Pro-Trade® line of products in the 2026 Fiscal Year.

Solstice®

We launched a line of premium imported natural stone under our Solstice® brand in 2024. The Solstice® line is sold exclusively through our branches and website, and includes three collections of products designed for hardscape, pool deck, and vertical masonry projects. The mix of products includes coping, caps, steps, treads, pavers, and stone veneer in a variety of materials that range from high grade versions already present in the market to materials exclusive to SiteOne in our target markets. We plan to continue expanding our Solstice® line of products in the 2026 Fiscal Year.

SiteOne Green Tech®

We offer pre-packaged landscape and irrigation management solutions that are designed to help customers manage and conserve water under the SiteOne Green Tech® brand. The core SiteOne Green Tech® product lines include central irrigation control systems, solar assemblies, fertilizer injection systems, irrigation pumps, and hand-held remote control equipment.

Portfolio®

We offer a line of premium plant varieties under our Portfolio® brand. The Portfolio® line of products is sold exclusively through our branches and website, and currently includes products specialized for the market, exclusive to the brand, or are improvements to the current plant standards in the industry. There are currently over 250 unique items in the line, in various sizes, including shrubs, trees, perennials, annuals, and bulbs. We plan to continue expanding our Portfolio® line of products in the 2026 Fiscal Year.

Services

We offer a variety of complementary, value-added services to support the sale of our products. We believe these services are an important differentiator in establishing our value proposition to our customers.

Product Knowledge and Technical Expertise

Consultative services provided by our local staff, many of whom are former landscape contractors or golf course superintendents, include product selection and support, assistance with design and implementation of landscape projects, and potential sales leads for new business opportunities. Our SiteOne University program provides customers with access to training and informational seminars that directly support the growth of their businesses. The program includes technical training, licensing, certifications, and business management seminars. In addition, our product category experts provide technical knowledge on the features and benefits of our products as well as installation techniques.

Project Services

We partner with our customers by providing consultative services to help them save time, money, and effort in bidding for new projects and for new landscape installations. Our regionally based project services teams specialize in quoting, estimating, and completing sales for customers who compete in the commercial construction sector. Other services provided by our project services teams include assistance with specifications and irrigation project take-offs.

Partners Program

We offer a loyalty rewards program, our Partners Program, which had approximately 62,000 enrolled customers as of December 28, 2025 and provides business and personal rewards, access to business services at preferred rates, and technical training and support. Reward points may be utilized, for example, for on-account credits, trips and special events, gift cards to major retailers, and SiteOne University courses and educational events. Access is also provided to preferred rate business services and includes, for example, payroll and select human resource services, cell phone services, office supplies, and fuel rebates. For the 2025 Fiscal Year, Partners Program participants accounted for approximately 62% of our Net sales.

Operational Structure

Our operational philosophy is to create local area teams and branch networks specifically designed to best meet our customers’ needs at the local market level, while supporting these teams with the resources of a large company delivered through regional and divisional management, including company-wide support functions.

At the local market level, we organize our over 670 branches and approximately 630 outside sales representatives into 39 designated “areas” that each typically serve a defined geography, a large MSA, or a combination of MSAs in close proximity. Area Managers are responsible for the organization and talent planning, branch operations, sales and product delivery strategy, and financial performance of their respective areas. Area Managers are assisted by Area Business Managers and Area Sales Managers who are responsible for executing the local market and operating strategies as well as key initiatives to grow sales and profitability.

We support our area teams with regional and divisional management as well as company-wide support functions by providing: management of business performance, development and execution of local strategies, sharing of best practices, execution and integration of acquisitions, finance and accounting expertise (including financial planning and analysis, credit/collections, payables, and other shared services), category management and procurement, supply chain (including planners and buyers), pricing strategies, marketing, and information technology. Branches that have been integrated into our systems utilize a single technology platform, allowing us to leverage our full operational scale for procurement, inventory management, delivery, financial support, data analytics, and performance reporting.

Our outside sales force is organized by geographic area. Each area maintains a number of outside sales representatives who drive sales growth on behalf of several branches across a variety of accounts from landscape contractors to municipal agencies. We also maintain a sales force of agronomic sales representatives who are focused on growing sales with customers in the golf industry. Our agronomic sellers also focus on contractors in the lawn care operations, maintenance and development, and sports turf verticals.

We have a national account sales organization that leads sales strategy and execution for our largest national and regional customers. The national sales team is organized around nine different market verticals: facility management, golf, international, lawn care operators, maintenance and development, pest control, retail, sod, and tree service accounts. Each national account manager is responsible for a group of large accounts and coordinates our business with these customers both nationally and locally through our local sales representatives. National account managers negotiate national programs with our largest customers in order to increase our share of their business.

Distribution Network

We use two distribution models to offer a comprehensive selection of products and meet the needs of each local market.

Branches

Our branch network is the core of our operations and creates a valuable connection between our suppliers and our customers. Of our approximately 6,000 suppliers, few are set up to serve the shipping needs of our customers as their supply chains are typically focused on bulk quantity shipments. In contrast, many of our customers often require comparatively small quantities of products from numerous suppliers to complete a typical project, making it difficult to source directly from those suppliers. Our branch network provides significant value to our suppliers by maintaining local availability of core and complementary products in quantities our customers need.

8

Table of Contents

The majority of our branches carry multiple product categories, but do not carry all. Branches that carry our full product lines combine our regular branch facilities with large 5-to-30 acre yards suitable for nursery goods and hardscapes products. Yards are well-equipped to manage truckload-purchased hardscapes, landscape accessories, and nursery goods, and can maintain a diverse variety of greenhouse and nursery plants. Locations offering nursery goods have water distribution systems to maintain inventories, and many of these locations have access to municipal water supplies, wells, or ponds. Branches are strategically located near residential areas with convenient highway access. In-store merchandising displays are utilized to emphasize product features and seasonal promotions. We primarily lease 5,000 to 15,000 square foot facilities in both freestanding and multi-tenant buildings with secured outside storage yards averaging from 10,000 to 20,000 square feet.

Direct Distribution

Our direct distribution business provides point-to-point logistics for bulk quantities of landscape products between suppliers and customers, providing customers with sourcing and logistics support services for inventory management and delivery, and in many cases, these services are more economical than the producers might otherwise provide. We believe that producers view us not as competitors, but as providers of a valuable service, brokering these large orders through the use of our network. We typically do not maintain inventory for direct distribution, but rather use our existing supplier relationships, marketing expertise, and ordering and logistics infrastructure to serve this demand, requiring less working capital investment for these sales. Approximately 7% of our 2025 Fiscal Year Net sales were from direct distribution.

Direct distribution is preferred for contractors with large projects, typically designed by professional landscape architects. Contractors work hand-in-hand with our outside sales and inside sales teams, including project planning support with material take-offs, product sourcing, and bid preparation. Using our large supplier network, our associates arrange convenient direct shipments to jobs, which are coordinated and staged according to each phase of the construction. This distribution channel primarily handles bulk hardscapes, agronomics, landscape accessories, and nursery goods products.

Customers

Our customers are primarily residential and commercial landscape professionals who specialize in the design, installation, and maintenance of lawns, gardens, golf courses, and other outdoor spaces. Our customer base consists of more than 440,000 firms and individuals, with our top 10 customers collectively accounting for less than 4% of our 2025 Fiscal Year Net sales, with no single customer accounting for more than 2% of Net sales. Small customers, with annual purchases of up to $25,000, made up 23% of our 2025 Fiscal Year Net sales. Medium customers, with annual purchases from $25,000 up to $150,000, made up 29% of our 2025 Fiscal Year Net sales. Large customers, with annual purchases over $150,000, made up 48% of our 2025 Fiscal Year Net sales. Some of our largest customers include BrightView, Weed Man, Juniper Landscaping, Aptive Environmental, Sperber, Yellowstone Landscape, Heartland, and Davey Tree. Distribution of our LESCO® proprietary branded products on a wholesale basis to retailers represented less than 1% of our 2025 Fiscal Year Net sales.

Suppliers

We source our products from approximately 6,000 suppliers, including the major irrigation equipment manufacturers, turf and ornamental fertilizer and chemical companies, and a variety of suppliers who specialize in hardscapes, nursery goods, outdoor lighting, and other landscape products. Some of our largest suppliers include Hunter Industries, Rain Bird, Oldcastle, Cresline, Envu, Turf Care Supply, NDS, Toro, Spears Manufacturing, and Techo-Bloc. Purchases from our top 10 suppliers accounted for approximately 30% of total purchases for the 2025 Fiscal Year.

Table of Contents

We generally procure our products through purchase orders rather than under long-term contractual arrangements with firm commitments. We work to develop strong relationships with a select group of suppliers that we target based on a number of factors, including brand and market recognition, price, quality, product support, service levels, delivery terms, and their strategic positioning. We typically have annual supplier agreements, and while these agreements generally do not provide for specific product pricing, many include volume-based financial incentives that are earned by meeting or exceeding purchase volume targets. Our ability to earn these volume-based incentives is an important factor in our financial results. Additionally, in certain cases, we enter into supply contracts with terms that exceed one year for the manufacture of our LESCO® branded fertilizer as well as grass seed, outdoor lighting, and hardscapes products, which may require us to purchase products in the future.

Competition

The majority of our competition comes from other wholesale landscape supply distributors. Among them, we primarily compete against a small number of regional distributors, as well as many small, local, privately-owned distributors. Some of our competitors carry several product categories, while others mainly focus on one product category such as hardscapes, irrigation supplies, fertilizer and control products, or nursery goods. We are the only national wholesale distributor to carry a full product line of landscape supplies.

We believe our top nine largest competitors include Heritage Landscape Supply Group (a subsidiary of The Home Depot), Ewing, Target Specialty Products, Harrell’s, Horizon Distributors (a subsidiary of Pool Corporation), BWI, Outdoor Living Supply, Central Pro Supply, and W.S. Connelly.

We believe regional and local competitors comprise approximately 81% of the landscape supply industry based on 2025 Net sales. The principal competitive factors in our business include, but are not limited to, location, availability of materials and supplies, technical product knowledge and expertise, advisory or other service capabilities, delivery capabilities, pricing of products, and availability of credit.

Human Capital Management and Sustainability

At SiteOne, we believe our associates are our greatest asset and the safety, health, and wellness of our associates and their families is a top priority. The support we offer to our associates is an important part of our vision to be a great place to work and the employer of choice in the green industry.

As of December 28, 2025, we employed approximately 8,200 associates, none of whom were affiliated with labor unions. We periodically administer a company-wide associate engagement survey, the most recent of which occurred in November 2025, and we believe that we have good relations with our associates. Approximately 93% of our associates are employed on a full-time, year-round basis. Our associate count included approximately 450 seasonal associates, who were temporarily employed due to the weather-dependent nature of our business. An associate is anyone employed by the Company.

Safety

We are committed to being “Always Safe,” which means that we take personal responsibility for our own safety and for the safety of others. Our leadership team is focused on creating a culture of safety and evaluating ways to improve our operations that reduce the most common forms of on-the-job injuries. Our safety program includes:

•Our Environmental, Health, and Safety team, which further enhances our safety efforts by establishing and monitoring safe work practices to prevent customer and associate injuries. As a result, we invest in safety equipment and practices at all branches with the goal of eliminating workplace injuries.

•A designated Safety Champion in each of our branches. Our Safety Champions are high potential, well-respected associates who help demonstrate and influence our culture of safety. Our goal is a robust culture of safety with all associates committed to working safely, every task, every day, 100% of the time.

Benefits

We offer a competitive benefits package with the goal of enabling our associates to get the most out of work and life. Among our benefits, we offer a paid military leave benefit that provides additional resources to our full-time associates as they continue to serve our country. We also offer a paid parental leave benefit for our full-time associates to help parents during the early days of parenthood. The parental leave benefit provides time away from work within the first year of the birth or adoption of a child with 100% of base pay.

SiteOne CARES is a grant assistance program designed to help our associates cope with unexpected financial challenges arising from personal hardships. As of December 28, 2025, we reached over $350,000 in associate donations since the program inception in 2022 and have assisted 74 associates in need.

We offer a bonus program for our hourly associates. In the 2025 Fiscal Year, approximately 3,940 associates received the bonus with payments totaling approximately $3.1 million. We continue to evaluate our compensation and benefits program to ensure we offer a competitive total rewards package.

Training and Development

We believe the training provided through our development programs and our entrepreneurial, performance-based culture delivers significant benefits to our associates. Targeted skills training is designed around an associate’s development and career interests. We offer certification programs that include instructor-led training, online learning, in-field work, and exit exams. We also facilitate leadership training to develop an understanding of leadership style, our values, and key coaching techniques.

Engagement

We administer associate engagement surveys to determine how we are doing in our mission to be the employer of choice in the green industry. We review the survey results with all of our associates and seek their involvement in developing and executing action plans to continue our workplace improvements. We monitor associate satisfaction and aim to strengthen our pipeline of top talent by conducting talent reviews and succession planning for all critical roles in the organization. We identify, communicate, and utilize career development paths for key roles. This includes not only an upward path for associates, but exposure to parallel roles across the organization.

At SiteOne, we believe in the power of teamwork and in creating a great place to work for all our associates. We focus on creating an environment that is respectful and supportive of each of our associates and which places the team first. We have several Associate Resource Groups (“ARGs”), which are voluntary, associate-led groups open to all SiteOne associates. ARGs support business objectives, foster an inclusive culture, and offer an avenue of development for associates. Our ARGs include the following:

•BR1DGE – BR1DGE provides a network to support and develop our Black associates.

•INSP1RE – INSP1RE fosters an inclusive culture with a focus on our extended Asian community.

•UN1DOS – UN1DOS attracts and retains engaged associates while enhancing SiteOne’s understanding of and relationships with Hispanic communities and customers.

•VETS1 – VETS1 fosters an environment of engaged associates while developing SiteOne’s understanding of and relationships with veteran associates, customers, and communities.

•W1GG – “Women in the Green Growing” promotes an environment of engaged associates while advocating female growth within SiteOne and the green industry.

Sustainability

We believe it is important to provide our stockholders with important information about our sustainability-related performance. As part of this commitment, we published our annual corporate responsibility report (“IMPACT Update”) in October 2025, which details our progress across various sustainability topics and includes disclosure of certain metrics relevant to our business and industry. We also engaged a leading consultant to review our greenhouse gas (“GHG”) emissions inventory and oversee data collection and gap analysis. We have made several investments in technology and processes that allow us to better gather data and track certain metrics related to our delivery fleet as well as utility expense management.

Service Marks, Trademarks, and Trade Names

We hold various trademark registrations, including SiteOne®, LESCO®, Pro-Trade®, Solstice®, SiteOne Green Tech®, and Portfolio®, which we consider important to our marketing activities. Generally, trademark rights have a perpetual life, provided they are renewed on a timely basis and continue to be used properly as trademarks. We intend to maintain these trademark registrations and the other trademarks associated with our business so long as they remain valuable to our business. In addition, other than commercially available software licenses, we do not believe that any of our licenses for third-party intellectual property are material to our business, taken as a whole.

Weather Conditions and Seasonality

For a discussion regarding seasonality and weather, refer to Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Weather Conditions and Seasonality” of this Annual Report on Form 10-K.

Regulatory Compliance

Government Regulations

We are subject to various federal, state, provincial, and local laws and regulations, compliance with which increases our operating costs, limits or restricts the products and services we provide or the methods by which we offer and sell those products and services or conduct our business, and subjects us to the possibility of regulatory actions or proceedings. Noncompliance with these laws and regulations can subject us to fines or various forms of civil or criminal prosecution, any of which could have a material adverse effect on our reputation, business, financial position, results of operations, and cash flows.

These federal, state, provincial, and local laws and regulations include, but are not limited to, laws relating to consumer protection, wage and hour, deceptive trade practices, international trade, anti-bribery and anti-corruption, permitting and licensing, state contractor laws, workers’ safety, tax, healthcare reforms, collective bargaining and other labor matters, environmental, data privacy, cybersecurity, and employee benefits.

Environmental, Health, and Safety Matters

We are subject to numerous federal, state, provincial, and local environmental, health and safety laws and regulations, including laws that regulate the emission or discharge of materials into the environment, govern the use, handling, treatment, storage, disposal, and management of hazardous substances and wastes, protect the health and safety of our associates and users of our products, and impose liability for investigating and remediating, and damages resulting from, present and past releases of hazardous substances at sites we have ever owned, leased or operated, or used as a disposal site.

In the United States, we are regulated under many environmental, health and safety laws, including, but not limited to, the Comprehensive Environmental Response, Compensation and Liability Act, the Federal Environmental Pesticide Control Act, the Federal Insecticide, Fungicide and Rodenticide Act, the Clean Air Act, the Clean Water Act, the Occupational Safety and Health Act, and the Consumer Product Safety Act, each as amended. Certain laws, such as those requiring the registration of herbicides and pesticides, and regulating their use, also involve the oversight of regulatory authorities and public health agencies. Although we strive to comply with such laws and have processes in place designed to achieve compliance, we may be unable to prevent violations of these or other laws from occurring. We could also incur significant investigation and clean-up costs for contamination at any currently or formerly owned or operated facilities, including LESCO’s manufacturing and blending facilities. Refer to “Note 10. Commitments and Contingencies” to our audited consolidated financial statements for additional information.

We cannot predict the effect of possible future environmental, health, or safety laws on our operations. Changes in, or new interpretations of, existing laws, regulations or enforcement policies, the discovery of previously unknown contamination, or the imposition of other environmental liabilities or obligations in the future, including obligations with respect to any potential health hazards of our products, may lead to additional compliance or other costs.
