Company Overview

We are the largest and only national wholesale distributor of landscape supplies in the United States and have a growing 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 February 20, 2018, we had 511 branch locations in 45 U.S. states and six Canadian provinces. Through our expansive North American network, we offer a comprehensive selection of more than 120,000 stock keeping units (“SKUs”) including irrigation supplies, fertilizer and control products (e.g., herbicides), landscape accessories, nursery goods, hardscapes (including paving, natural stone and blocks), 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 network design, commercial project planning, generation of sales leads, marketing services and product support, 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 1,400 delivery vehicles position us well to meet the needs of our customers and ensure timely delivery of products. We source our products from approximately 3,000 suppliers, including the major irrigation equipment manufacturers, turf and ornamental fertilizer/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. We derived approximately 55% of our 2017 Fiscal Year net sales from the residential construction sector, 31% from the commercial (including institutional) construction sector and 14% from the recreational and other construction sector. By end market, we derived approximately 41% of our 2017 Fiscal Year net sales from maintenance of residential, commercial and recreational properties. The recurring nature of landscape maintenance demand helps to provide stability in our financial performance across economic cycles. Fertilizer and control products are the primary products used in maintenance. The sale of products relating to new construction of homes, commercial buildings and recreational spaces accounted for approximately 40% of our 2017 Fiscal Year net sales. These products primarily include irrigation, nursery, hardscapes, outdoor lighting and landscape accessories. Approximately 19% of our 2017 Fiscal Year net sales were derived from sales of products for the repair and upgrade of existing landscapes. These sales benefit from increasing existing home sales, increasing home prices and rising consumer spending.

Net Sales for 2017 Fiscal Year

Our History

Our company was established in 2001 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 (the “CD&R Investor”) 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 (“IPO”) of our common stock in which Deere and the CD&R Investor were the sole sellers of our common stock to the public. On December 5, 2016, May 1, 2017 and July 26, 2017, we completed secondary offerings of our common stock in which Deere and CD&R Investor were the sole sellers.

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 $18 billion in revenue in 2017. Growth in our industry is driven by a broad array of factors, including consumer spending, housing starts, existing home sales, home prices, commercial construction, repair and remodeling spending, and demographic trends. Within the wholesale landscape supply distribution industry, products sold for residential applications represent the largest construction sector, followed by the commercial and recreational & 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 control products, hardscapes, irrigation products and outdoor lighting, and fertilizer & other accounting for approximately one-tenth of industry sales.

The wholesale landscape supply distribution 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, such as lawn care, tree and foliage maintenance firms. 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 “one-stop shop” with a larger variety of products 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 Expand 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 230,000 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 continue to increase 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 offering for our customers at competitive prices and enhance our role as a critical player in the supply chain.

4

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 offer our full product line in only 26% of the metropolitan statistical areas (“MSAs”) in the United States 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 recently completed acquisitions, we have added new markets in the United States 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 grow our market share and enhance our local market leadership positions by taking advantage of our scale, operational experience and acquisition know-how to pursue and integrate attractive targets. In addition, we currently have branches in 183 of the 381 U.S. MSAs and are focused on identifying and reviewing 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 corporate 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 pricing and category management capabilities, streamline and refine our marketing process and invest in more sophisticated information technology systems and data analytics.  Additionally, we have commenced our e-commerce initiative, to include the relaunch of our website and implementation of a business-to-business (B2B) e-commerce platform.  Although we are still in the early stages of these initiatives, they have already contributed to improvement in our profitability, and we believe we will continue to benefit from these and other operational improvements.

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, while at the area and branch level we have built a vibrant and entrepreneurial culture that rewards performance. We promote ongoing, open and honest communication with our associates 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 over 120,000 SKUs from approximately 3,000 suppliers. Our product portfolio includes irrigation, fertilizer & other, control products, landscape accessories, nursery goods, hardscapes 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 that items such as nursery goods and hardscapes require provides us with a competitive advantage over many competitors who offer a more limited selection of product categories.

See Note 12 to our audited financial statements for information on our net sales in the agronomic (fertilizer & other and control products), irrigation and outdoor lighting, landscape accessories and hardscapes and nursery goods categories.

Irrigation

Our irrigation products include controllers, valves, sprinkler heads and irrigation and drainage pipes. The market for irrigation products has historically provided stable growth and is driven primarily by new home construction and maintenance of existing irrigation systems.

Fertilizer & Other

Our fertilizer & other products include fertilizer, grass seed and ice melt products. Fertilizer products are sold to the maintenance end market and accordingly are relatively stable through economic cycles.

5

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.

Landscape Accessories

Our landscape accessories products include mulches, soil amendments, 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 nursery goods and hardscape products.

Nursery Goods

Our nursery goods include deciduous shrubs, evergreen shrubs and trees, ornamental trees, shade trees, both field grown and container-grown nursery stock and hundreds of plant species and cultivars available in a number of heights and bloom colors. 

Outdoor Lighting

Our outdoor lighting products include accent lights, dark lights, path lights, up lights, down lights, wall lights and pool and aquatic area lighting.

Hardscapes

Hardscapes include paving, natural stone, blocks and other durable materials.

Proprietary Branded Products

In addition to distributing branded products of third parties, we offer products under our proprietary brands. Sales of LESCO^®, Green Tech and Pro-Trade^® together accounted for approximately 14% of our 2017 Fiscal Year net sales, the large majority of which is attributable to LESCO^®.

LESCO

LESCO^® is a premium brand and 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, maintenance products like engine oil, windshield washer fluid, ice melt, trimmer line and soil tests. We also offer Basic Seed and Basic Nutrition, “sub-brands” of LESCO^®, under which we offer fertilizer and landscape accessories. LESCO^® products are sold through our branches and retail outlets such as The Home Depot, True Value and Ace Hardware.

Green Tech

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

Pro-Trade

In 2017, we launched a line of professional-grade LED lamps and lighting solutions under our Pro-Trade^® brand.  The Pro-Trade^® line of products is sold exclusively through our branches and currently includes lamps, brass and aluminum fixtures and transformers.

Services

We offer a variety of complementary, value-added services to support the sale of our products. We do not derive separate revenue for these services, but we believe they are an important differentiator in establishing our value proposition to our customers.

6

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 substantive 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 products we provide as well as on job 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 specifications assistance and irrigation design.

Partners Program

We offer a loyalty program, our Partners Program, which had approximately 17,000 enrolled customers as of December 31, 2017 and provides business and personal rewards, access to business services at preferred rates and technical training and support. Reward points may be spent, for example, on credit on account, trips and special events, gift cards to major retailers and SiteOne University courses and educational events. Access to preferred rate business services includes, for example, payroll and select human resources services, cell phone services, office supplies, auto and fleet insurance and fuel rebates. For the 2017 Fiscal Year, Partners Program participants accounted for approximately 54% 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 corporate functions.

At the local market level, we organize our 511 branches and approximately 350 outside sales representatives into 50 designated “areas” that each serve a defined geography, typically a large MSA or a combination of MSAs in close proximity. Area managers are responsible for organization and talent planning, branch operations, sales strategy and product delivery strategy. Area managers are supported by an area business manager responsible for executing the local market strategies and key initiatives to grow sales and profitability.

We support our 511 branches and 50 areas with regional management and company-wide corporate functions providing: management of business performance; development and execution of local strategies; sharing of best practices; execution and integration of acquisitions; finance and accounting expertise (credit/collections, payables); category management and procurement; supply chain (planners, buyers); pricing strategies; marketing; and information technology. Our branches are integrated on a single technology platform, allowing us to leverage our full operational scale for procurement, inventory management, 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 to the golf industry.

We have a national account sales organization which leads sales strategy and execution for our largest national and regional customers. The national sales team is organized around five different market verticals: landscape and grounds maintenance, golf, retail, international and environmental accounts. Each national account manager is responsible for a group of large accounts and coordinates our business with them 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.

7

Branches

Our branch network is the core of our operations and creates a valuable connection between our suppliers and our customers.  Of our approximately 3,000 suppliers, few are set up to serve the shipping needs of our customers as their supply chains are typically focused on bulk quantities shipped from only a few locations. In contrast, many of our customers often require comparatively small quantities of products from numerous suppliers to complete a typical project, making it unfeasible 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.

The majority of our branches carry multiple product categories but do not carry all of them. Branches that carry our full product lines combine our regular branch facilities with large 8-to-15 acre yards suitable for nursery goods and hardscape products. Yards are well-equipped to manage truckload-purchased landscape, nursery and hardscape products and can maintain a diverse variety of greenhouse and nursery plants. All locations offering nursery goods have water distribution systems to maintain inventories, and many of these locations have access to municipal water supply, wells or ponds.  Branches are strategically located near residential areas with good 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 in some branches.

Direct Distribution

Our direct distribution business provides point-to-point logistics for bulkquantities of landscape products between producers and customers. Our direct distribution business provides customers with sourcing and logistics support services for inventory management and delivery, in many cases more economically 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 producer relationships, marketing expertise and ordering and logistics infrastructure to serve this demand, requiring less working capital investment for these sales. Approximately 7% of our 2017 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 vendor network, our associates arrange convenient direct shipments to jobs, coordinated and staged according to each phase of construction. This distribution channel primarily handles bulk nursery, agronomic, landscape and hardscape 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 230,000 firms and individuals, with our top 10 customers collectively accounting for approximately 4% of our 2017 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 31% of our 2017 Fiscal Year net sales. Medium customers, with annual purchases between $25,000 and $150,000, made up 27% of our 2017 Fiscal Year net sales. Large customers, with annual purchases over $150,000, made up 42% of our 2017 Fiscal Year net sales. Some of our largest customers include BrightView, The Home Depot, Davey Tree Expert Company and TruGreen. Distribution of our LESCO proprietary branded products on a wholesale basis to retailers represented less than 1% of our 2017 Fiscal Year net sales.

Suppliers

We source our products from approximately 3,000 suppliers, including the major irrigation equipment manufacturers, turf and ornamental fertilizer/chemical companies, and a variety of suppliers who specialize in nursery goods, outdoor lighting, hardscapes and other landscape products. Some of our largest suppliers include Hunter, Rain Bird, Toro, Oldcastle, Bayer, Syngenta, BASF, Dow AgroSciences, Vista and NDS. Purchases from our top 10 suppliers accounted for approximately 39% of total purchases for our 2017 Fiscal Year.

We generally procure our products through purchase orders rather than under long-term contracts 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 and service, service levels, delivery terms and their strategic positioning. We generally have annual supplier agreements, and while they generally do not provide for specific product pricing, many include volume-based financial incentives that we earn by meeting or exceeding target purchase volumes. Our ability to earn these volume-based incentives is an important factor in our financial results. In limited cases, we have entered into supply contracts with terms that exceed one year for

8

the manufacture of our LESCO branded fertilizer and some nursery goods and grass seed, which may require us to purchase products in the future.

Competition

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

We believe our top nine largest competitors include Ewing, Harrell’s, Horizon Distributors (a subsidiary of Pool Corporation), Winfield Solutions, BWI, Target Specialty Products, Howard Fertilizer and Chemical, BFG Supply and Central Turf & Irrigation Supply.

We believe smaller, regional or local competitors still comprise approximately 90% of the landscape supply industry based on 2017 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.

Associates

As of February 20, 2018, we had approximately 3,800 associates, none of whom were affiliated with labor unions. We believe that we have good relations with our associates. Additionally, we believe that the training provided through our development programs and our entrepreneurial, performance-based culture provides significant benefits to our associates. Approximately 92.8% of our associates are employed on a full-time, year-round basis. Our associate count currently includes approximately 260 seasonal associates, who are temporarily employed due to the weather-dependent nature of our business. An associate is anyone employed by the Company.

Service Marks, Trademarks and Trade Names

We hold various trademark registrations, including SiteOne^® and LESCO^®, which we consider important to our marketing activities. Generally, trademark rights have a perpetual life, provided that 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, see 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 laws relating to consumer protection, wage and hour, deceptive trade practices, permitting and licensing, state contractor laws, workers’ safety, tax, healthcare reforms, collective bargaining and other labor matters, environmental 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

9

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 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 and the Occupational Safety and Health 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. See “Note 10. Commitments and Contingencies” to our audited consolidated financial statements included in this Annual Report on Form 10-K.

In addition, 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.

Item 1A. Risk Factors

You should carefully consider the factors described below, in addition to the other information set forth in this Annual Report on Form 10-K. These risk factors are important to understanding the contents of this Annual Report on Form 10-K and of other reports. Our reputation, business, financial position, results of operations and cash flows are subject to various risks. The risks and uncertainties described below are not the only ones relevant to us. Additional risks and uncertainties not currently known to us or that we currently believe are immaterial may also adversely impact our reputation, business, financial position, results of operations and cash flows.

Risks Related to Our Business and Our Industry

Cyclicality in our business could result in lower net sales and reduced cash flows and profitability. We have been, and in the future may be, adversely impacted by declines in the new residential and commercial construction sectors, as well as in spending on repair and upgrade activities.

We sell a significant portion of our products for landscaping activities associated with new residential and commercial construction sectors, which have experienced cyclical downturns, some of which have been severe. The strength of these markets depends on, among other things, housing starts, consumer spending, non-residential construction spending activity and business investment, which are a function of many factors beyond our control, including interest rates, employment levels, availability of credit, consumer confidence and capital spending. Weakness or downturns in residential and commercial construction markets could have a material adverse effect on our business, operating results or financial condition.

Sales of landscape supplies to contractors serving the residential construction sector represent a significant portion of our business, and demand for our products is highly correlated with new residential construction. Housing starts are dependent upon a number of factors, including housing demand, housing inventory levels, housing affordability, foreclosure rates, demographic changes, the availability of land, local zoning and permitting processes, the availability of construction financing and the health of the economy and mortgage markets. Unfavorable changes in any of these factors could adversely affect consumer spending, result in decreased demand for homes and adversely affect our business. Some analysts project that the demand for residential construction may be negatively impacted as the number of renting households has increased in recent years and as a shortage in the supply of affordable housing is expected to result in lower home ownership rates. The timing and extent of any recovery in homebuilding activity and the resulting impact on demand for landscape supplies are uncertain.

Our net sales also depend, in significant part, on commercial construction, which similarly recently experienced a severe downturn. Previously, downturns in the commercial construction market have typically lasted about two to three years, resulting in market declines of approximately 20% to 40%, while the most recent downturn in the commercial construction market lasted over four years, resulting in a market decline of approximately 60%. We cannot predict the duration of the current market conditions or the timing or strength of any future recovery of commercial construction activity in our markets.

We also rely, in part, on repair and upgrade of existing landscapes. High unemployment levels, high mortgage delinquency and foreclosure rates, lower home prices, limited availability of mortgage and home improvement financing, and significantly lower housing turnover, may restrict consumer spending, particularly on discretionary items such as landscape projects, and adversely affect consumer confidence levels and result in reduced spending on repair and upgrade activities.

Our business is affected by general business, financial market and economic conditions, which could adversely affect our financial position, results of operations and cash flows.

Our business and results of operations are significantly affected by general business, financial market and economic conditions. General business, financial market and economic conditions that could impact the level of activity in the wholesale landscape supply industry include the level of new home sales and construction activity, interest rate fluctuations, inflation, unemployment levels, tax rates, capital spending, bankruptcies, volatility in both the debt and equity capital markets, liquidity of the global financial markets, the availability and cost of credit, investor and consumer confidence, global economic growth, local, state and federal government regulation, and the strength of regional and local economies in which we operate. With respect to the residential construction sector in particular, spending on landscape projects is largely discretionary and lower levels of consumer spending or the decision by home-owners to perform landscape upgrades or maintenance themselves rather than outsource to contractors may adversely affect our business.

Seasonality affects the demand for our products and services and our results of operations and cash flows.

The demand for our products and services and our results of operations are affected by the seasonal nature of our irrigation, outdoor lighting, nursery, landscape accessories, fertilizers, turf protection products, grass seed, turf care equipment and golf course maintenance supplies. Such seasonality causes our results of operations to vary considerably from quarter to quarter. Typically, our net

11

sales and net income have been higher in the second and third quarters of each fiscal year due to favorable weather and longer daylight conditions during these quarters. Our net sales and net income, however, are significantly lower in the first and fourth quarters due to lower landscaping, irrigation and turf maintenance activities in these quarters. Accordingly, results for any quarter are not necessarily indicative of the results that may be achieved for the full fiscal year.

Our operations are substantially dependent on weather conditions.

We supply landscape, irrigation and turf maintenance products, the demand for each of which is affected by weather conditions, including, without limitation, potential impacts, if any, from climate change. In particular, droughts could cause shortage in the water supply, which may have an adverse effect on our business. For instance, our supply of plants could decrease, or prices could rise, due to such water shortages, and customer demand for certain types of plants may change in ways in which we are unable to predict. Such water shortages may also make irrigation or the maintenance of turf uneconomical. Governments may implement limitations on water usage that make effective irrigation or turf maintenance unsustainable, which could negatively impact the demand for our products. In California, for instance, mandatory water restrictions went into effect across the state in 2015. We have also recently seen an increased demand in California for products related to drought-tolerant landscaping, including hardscapes and plants that require low amounts of water. There is a risk that demand for landscaping products will decrease overall due to persistent drought conditions in some of the geographic markets we serve, or that demand will change in ways that we are unable to predict.

Furthermore, adverse weather conditions, such as droughts, severe storms, hurricanes and significant rain or snowfall, can adversely impact the demand for our products, timing of product delivery, or our ability to deliver products at all. For example, severe winter storms can cause hazardous road conditions, which may prevent personnel from traveling or delivering to service locations. In addition, unexpectedly severe weather conditions, such as excessive heat or cold, may result in certain applications in the maintenance product cycle being omitted for a season or damage to or loss of nursery goods, sod and other green products in our inventory, which could result in losses requiring writedowns.

Public perceptions that the products we use and the services we deliver are not environmentally friendly or safe may adversely impact the demand for our products or services.

We sell, among other things, fertilizers, herbicides, fungicides, pesticides, rodenticides and other chemicals. Public perception that the products we use and the services we deliver are not environmentally friendly or safe or are harmful to humans or animals, whether justified or not, or the improper application of these chemicals, could reduce demand for our products and services, increase regulation or government restrictions or actions, result in fines or penalties, impair our reputation, involve us in litigation, damage our brand names and otherwise have a material adverse impact on our business, financial position, results of operations and cash flows.

Our industry and the markets in which we operate are highly competitive and fragmented, and increased competitive pressures could reduce our share of the markets we serve and adversely affect our business, financial position, results of operations and cash flows.

We operate in markets with relatively few large competitors, but barriers to entry in the landscape supply industry are generally low, and we may have several competitors within a local market area. Competition varies depending on product line, type of customer and geographic area. Some local competitors may be able to offer higher levels of service or a broader selection of inventory than we can in particular local markets. As a result, we may not be able to continue to compete effectively with our competitors. Any of our competitors may foresee the course of market development more accurately than we do, provide superior service, sell or distribute superior products, have the ability to supply or deliver similar products and services at a lower cost, or on more favorable credit terms, develop stronger relationships with our customers and other consumers in the landscape supply industry, adapt more quickly to evolving customer requirements than we do, develop a superior network of distribution centers in our markets or access financing on more favorable terms than we can obtain. As a result, we may not be able to compete successfully with our competitors.

Competition can also reduce demand for our products and services, negatively affect our product sales and services or cause us to lower prices. Consolidation of professional landscape service firms may result in increased competition for their business. Certain product manufacturers that sell and distribute their products directly to landscapers may increase the volume of such direct sales. Our suppliers may also elect to enter into exclusive supplier arrangements with other distributors.

Former associates may start landscape supply businesses similar to ours, in competition with us. Our industry faces low barriers to entry, making the possibility of former associates starting similar businesses more likely. Increased competition from businesses started by former associates may reduce our market share and adversely affect our business, financial position, results of operations and cash flows.

Our customers consider the performance of the products we distribute, our customer service and price when deciding whether to use our services or purchase the products we distribute. Excess industry capacity for certain products in several geographic markets

12

could lead to increased price competition. We may be unable to maintain our operating costs or product prices at a level that is sufficiently low for us to compete effectively. If we are unable to compete effectively with our existing competitors or new competitors enter the markets in which we operate, our financial condition, operating results and cash flows may be adversely affected.

Product shortages, loss of key suppliers, failure to develop relationships with qualified suppliers or dependence on third-party suppliers and manufacturers could affect our financial health.

Our ability to offer a wide variety of products to our customers is dependent upon our ability to obtain adequate product supply from manufacturers and other suppliers. Any disruption in our sources of supply, particularly of the most commonly sold items, could result in a loss of revenues, reduced margins and damage to our relationships with customers. Supply shortages may occur as a result of unanticipated increases in demand or difficulties in production or delivery. When shortages occur, our suppliers often allocate products among distributors. The loss of, or a substantial decrease in the availability of, products from our suppliers or the loss of key supplier arrangements could adversely impact our financial condition, operating results, and cash flows.

Our ability to continue to identify and develop relationships with qualified suppliers who can satisfy our high standards for quality and our need to be supplied with products in a timely and efficient manner is a significant challenge. Our suppliers’ ability to provide us with products can also be adversely affected in the event they become financially unstable, particularly in light of continuing economic difficulties in various regions of the United States and the world, fail to comply with applicable laws, encounter supply disruptions, shipping interruptions or increased costs, or face other factors beyond our control.

Our agreements with suppliers are generally terminable by either party on limited notice, and in some cases we do not have written agreements with our suppliers. If market conditions change, suppliers may stop offering us favorable terms. Our suppliers may increase prices or reduce discounts on the products we distribute and we may be unable to pass on any cost increase to our customers, thereby resulting in reduced margins and profits. Failure by our suppliers to continue to supply us with products on favorable terms, commercially reasonable terms, or at all, could put pressure on our operating margins or have a material adverse effect on our financial condition, results of operations and cash flows.

The prices and costs of the products we purchase may be subject to large and significant price fluctuations. We might not be able to pass cost increases through to our customers, and we may experience losses in a rising price environment. In addition, we might have to lower our prices in a declining price environment, which could also lead to losses.

We purchase and sell a wide variety of products, the price and availability of which may fluctuate, and may be subject to large and significant price increases. Many of our contracts with suppliers include prices for commodities such as grass seed and chemicals used in fertilizer that are not fixed or are tied to an index, which allows our suppliers to change the prices of their products as the input prices fluctuate. Our business is exposed to these fluctuations, as well as to fluctuations in our costs for transportation and distribution. Changes in prices for the products that we purchase affect our net sales and cost of goods sold, as well as our working capital requirements, levels of debt and financing costs. We might not always be able to reflect increases in our costs in our own pricing. Any inability to pass cost increases on to customers may adversely affect our business, financial condition and results of operations. In addition, if market prices for the products that we sell decline, we may realize reduced profitability levels from selling such products and lower revenues from sales of existing inventory of such products.

We are subject to inventory management risks; insufficient inventory may result in lost sales opportunities or delayed revenue, while excess inventory may harm our gross margins.

We balance the need to maintain inventory levels that are sufficient to ensure competitive lead times against the risk of inventory obsolescence because of changing customer requirements, fluctuating commodity prices, or the life-cycle of nursery goods, sod and other green products. In order to successfully manage our inventories, including grass seed, chemicals used in fertilizers, and nursery goods, sod and other green products, we must estimate demand from our customers and purchase products that substantially correspond to that demand. If we overestimate demand and purchase too much of a particular product, we face a risk that the price of that product will fall, leaving us with inventory that we cannot sell profitably. In addition, we may have to write down such inventory if we are unable to sell it for its recorded value. Contracts with certain suppliers require us to take on additional inventory or pay a penalty, even in circumstances where we have excess inventory. By contrast, if we underestimate demand and purchase insufficient quantities of a product and the price of that product were to rise, we could be forced to purchase that product at a higher price and forego profitability in order to meet customer demand. Insufficient inventory levels may lead to shortages that result in delayed revenue or loss of sales opportunities altogether as potential end-customers turn to competitors’ products that are readily available. Our business, financial condition and results of operations could suffer a material adverse effect if either or both of these situations occur frequently or in large volumes.

13

Many factors, such as weather conditions, agricultural limitations and restrictions relating to the management of pests and disease, affect the supply of nursery goods, grass seed, sod and other green products. If the supply of these products available is limited, prices could rise, which could cause customer demand to be reduced and our revenues and gross margins to decline. For example, nursery goods, sod and grass seed are perishable and have a limited shelf life. Should we be unable to sell our inventory of nursery goods, grass seed, sod and other green products within a certain timeframe, we may face losses requiring write-downs. In contrast, we may not be able to obtain high-quality nursery goods and other green products in an amount sufficient to meet customer demand. Even if available, nursery goods from alternate sources may be of lesser quality or may be more expensive than those currently grown or purchased by us. If we are unable to effectively manage our inventory and that of our distribution partners, our results of operations could be adversely affected.

We may not successfully implement our business strategies, including achieving our growth objectives.

We may not be able to fully implement our business strategies or realize, in whole or in part within the expected time frames, the anticipated benefits of our various growth or other initiatives. Our various business strategies and initiatives, including our growth, operational and management initiatives, are subject to significant business, economic and competitive uncertainties and contingencies, many of which are beyond our control. The execution of our business strategy and our financial performance will continue to depend in significant part on our executive management team and other key management personnel, the smooth transition of new senior leadership and our executive management team’s ability to execute the new operational initiatives that they are undertaking. In addition, we may incur certain costs as we pursue our growth, operational and management initiatives, and we may not meet anticipated implementation timetables or stay within budgeted costs. As these initiatives are undertaken, we may not fully achieve our expected efficiency improvements or growth rates, or these initiatives could adversely impact our customer retention, supplier relationships or operations. Also, our business strategies may change from time to time in light of our ability to implement our business initiatives, competitive pressures, economic uncertainties or developments, or other factors.

We may be unable to successfully acquire and integrate other businesses.

Our historical growth has been driven in part by acquisitions, and future acquisitions are an important element of our business strategy. We may be unable to continue to grow our business through acquisitions. We may not be able to continue to identify suitable acquisition targets and may face increased competition for these acquisition targets. In addition, acquired businesses may not perform in accordance with expectations, and our business judgments concerning the value, strengths and weaknesses of acquired businesses may not prove to be correct. We may also be unable to achieve expected improvements or achievements in businesses that we acquire. At any given time, we may be evaluating or in discussions with one or more acquisition targets, including entering into non-binding letters of intent. Future acquisitions may result in the incurrence of debt and contingent liabilities, legal liabilities, goodwill impairments, increased interest expense and amortization expense and significant integration costs.

Acquisitions involve a number of special risks, including:

• our inability to manage acquired businesses or control integration costs and other costs relating to acquisitions;

• potential adverse short-term effects on operating results from increased costs or otherwise;

• diversion of management’s attention;

• failure to retain existing customers or key personnel of the acquired business and recruit qualified new associates at the location;

• failure to successfully implement infrastructure, logistics and systems integration;

• potential impairment of goodwill;

• risks associated with the internal controls of acquired companies;

• exposure to legal claims for activities of the acquired business prior to acquisition and inability to realize on any indemnification claims, including with respect to environmental and immigration claims;

• the risks inherent in the systems of the acquired business and risks associated with unanticipated events or liabilities; and

• our inability to obtain financing necessary to complete acquisitions on attractive terms or at all.

Our strategy could be impeded if we do not identify, or face increased competition for, suitable acquisition targets, and such increased competition could result in higher purchase price multiples we have to pay for acquisition targets or reduce the number of suitable targets. Our business, financial condition, results of operations and cash flows could be adversely affected if any of the foregoing factors were to occur.

Increases in operating costs could adversely impact our business, financial position, results of operations and cash flows.

Our financial performance is affected by the level of our operating expenses, such as occupancy costs associated with the leases for our branch locations and costs of fuel, vehicle maintenance, equipment, parts, wages and salaries, employee benefits, health care, self-insurance costs and other insurance premiums as well as various regulatory compliance costs, all of which may be subject to inflationary pressures. In particular, our financial performance is adversely affected by increases in these operating costs.

14

Most of our facilities are located in leased premises. Many of our current leases are non-cancelable and typically have terms ranging from three to five years, with options to renew for specified periods of time. We believe that leases we enter into in the future will likely be long-term and non-cancelable and have similar renewal options. However, we may be unable to renew our current or future leases on favorable terms or at all which could have an adverse effect on our operations and costs. In addition, if we close a location, we generally remain committed to perform our obligations under the applicable lease, which include, among other things, payment of the base rent for the balance of the lease term.

We deliver a substantial volume of products to our customers by truck. Petroleum prices have fluctuated significantly in recent years. Prices and availability of petroleum products are subject to political, economic and market factors that are outside our control. Political events in petroleum-producing regions as well as hurricanes and other weather-related events may cause the price of fuel to increase. Our operating profit will be adversely affected if we are unable to obtain the fuel we require or to fully offset the anticipated impact of higher fuel prices through increased prices or fuel surcharges to our customers. Besides passing fuel costs on to customers, we have not entered into any hedging arrangements that protect against fuel price increases and we do not have any long-term fuel purchase contracts. If shortages occur in the supply of necessary petroleum products and we are not able to pass along the full impact of increased petroleum prices to our customers, our results of operations would be adversely affected.

We cannot predict the extent to which we may experience future increases in costs of occupancy, fuel, vehicle maintenance, equipment, parts, wages and salaries, employee benefits, health care, self-insurance costs and other insurance premiums as well as various regulatory compliance costs and other operating costs. To the extent such costs increase, we may be prevented, in whole or in part, from passing these cost increases through to our existing and prospective customers, and the rates we pay to our suppliers may increase, any of which could have a material adverse impact on our business, financial position, results of operations and cash flows.

Risks associated with our large labor force could have a significant adverse effect on our business.

We have an employee base of approximately 3,800 associates. Various federal and state labor laws govern our relationships with our associates and affect our operating costs. These laws include employee classifications as exempt or non-exempt, minimum wage requirements, unemployment tax rates, workers’ compensation rates, overtime, family leave, anti-discrimination laws, safety standards, payroll taxes, citizenship requirements and other wage and benefit requirements for employees classified as non-exempt. As our associates may be paid at rates that relate to the applicable minimum wage, further increases in the minimum wage could increase our labor costs. Associates may make claims against us under federal or state laws, which could result in significant costs. Significant additional government regulations, including the Employee Free Choice Act, the Paycheck Fairness Act and the Arbitration Fairness Act, could materially affect our business, financial condition and results of operations. In addition, we compete with other companies for many of our associates in hourly positions, and we invest significant resources to train and motivate our associates to maintain a high level of job satisfaction. Our hourly employment positions have historically had high turnover rates, which can lead to increased spending on training and retention and, as a result, increased labor costs. If we are unable to effectively retain highly qualified associates in the future, it could adversely impact our business, financial position, results of operations and cash flows.

None of our associates are currently covered by collective bargaining or other similar labor agreements. However, if a larger number of our associates were to unionize, including in the wake of any future legislation that makes it easier for associates to unionize, our business could be negatively affected. Any inability by us to negotiate collective bargaining arrangements could cause strikes or other work stoppages, and new contracts could result in increased operating costs. If any such strikes or other work stoppages occur, or if other associates become represented by a union, we could experience a disruption of our operations and higher labor costs.

In addition, certain of our suppliers have unionized work forces and certain of our products are transported by unionized truckers. Strikes, work stoppages or slowdowns could result in slowdowns or closures of facilities where the products that we sell are manufactured or could affect the ability of our suppliers to deliver such products to us. Any interruption in the production or delivery of these products could delay or reduce availability of these products and increase our costs.

We depend on a limited number of key personnel. We may not be able to attract or retain key executives, which could adversely impact our business and inhibit our ability to operate and grow successfully.

We depend upon the ability and experience of a number of our executive management and other key personnel who have substantial experience with our operations and within our industry, including Doug Black, our Chief Executive Officer. The loss of the services of one or a combination of our senior executives or key employees could have a material adverse effect on our results of operations. Our business may also be negatively impacted if one of our senior executives or key employees is hired by a competitor. Our success also depends on our ability to continue to attract, manage and retain other qualified management personnel as we grow. We may not be able to continue to attract or retain such personnel in the future.

An impairment of goodwill and/or other intangible assets could reduce net income.

15

Acquisitions frequently result in the recording of goodwill and other intangible assets. As of December 31, 2017, goodwill represented approximately 12% of our total assets. Goodwill is not amortized for financial reporting purposes and is subject to impairment testing at least annually using a fair-value based approach. The identification and measurement of goodwill impairment involves the estimation of the fair value of our reporting units. Our accounting for impairment contains uncertainty because management must use its judgment in determining appropriate assumptions to be used in the measurement of fair value. We determine the fair values of our reporting units by using both a market and income approach.

We evaluate the recoverability of goodwill for impairment in between our annual tests when events or changes in circumstances indicate that the carrying amount of goodwill may not be recoverable. Any impairment of goodwill will reduce net income in the period in which the impairment is recognized.

Adverse credit and financial market events and conditions could, among other things, impede access to, or increase the cost of, financing or cause our customers to incur liquidity issues that could lead to some of our products not being purchased or being cancelled, or result in reduced operating revenue and net income, any of which could have an adverse impact on our business, financial position, results of operations and cash flows.

Disruptions in credit or financial markets could, among other things, lead to impairment charges, make it more difficult for us to obtain, or increase our cost of obtaining, financing for our operations or investments or to refinance our indebtedness, cause our lenders to depart from prior credit industry practice and not give technical or other waivers under the Credit Facilities (as defined under “-Risks Related to Our Substantial Indebtedness” below), to the extent we may seek them in the future, thereby causing us to be in default under one or more of the Credit Facilities. These disruptions could also cause our customers to encounter liquidity issues that could lead to a reduction in the amount of our products purchased or services used, could result in an increase in the time it takes our customers to pay us, or could lead to a decrease in pricing for our products, any of which could adversely affect our accounts receivable, among other things, and, in turn, increase our working capital needs. In addition, adverse developments at federal, state and local levels associated with budget deficits resulting from economic conditions could result in federal, state and local governments increasing taxes or other fees on businesses, including us, to generate more tax revenues, which could negatively impact spending by customers on our products.

The majority of our net sales are derived from credit sales, which are made primarily to customers whose ability to pay is dependent, in part, upon the economic strength of the geographic areas in which they operate, and the failure to collect monies owed from customers could adversely affect our working capital and financial condition.

The majority of our net sales in our 2017 Fiscal Year were derived from the extension of credit to our customers whose ability to pay is dependent, in part, upon the economic strength of the areas where they operate. We offer credit to customers, generally on a short-term basis, either through unsecured credit that is based solely upon the creditworthiness of the customer, or secured credit for materials sold for a specific project where we establish a security interest in the material used in the project. The type of credit we offer depends on the customer’s financial strength. If any of our customers are unable to repay credit that we have extended in a timely manner, or at all, our working capital, financial condition, operating results and cash flows would be adversely affected. Further, our collections efforts with respect to non-paying or slow-paying customers could negatively impact our customer relations going forward.

Because we depend on certain of our customers to repay extensions of credit, if the financial condition of our customers declines, our credit risk could increase as a result. Significant contraction in the residential and non-residential construction markets, coupled with limited credit availability and stricter financial institution underwriting standards, could adversely affect the operations and financial stability of certain of our customers. Should one or more of our larger customers declare bankruptcy, it could adversely affect the collectability of our accounts receivable, bad debt reserves and net income.

Because we operate our business through highly dispersed locations across the United States, our operations may be materially adversely affected by inconsistent practices and the operating results of individual branches may vary.

We operate our business through a network of highly dispersed locations throughout the United States, supported by corporate executives and services in our headquarters, with local branch management retaining responsibility for day-to-day operations and adherence to applicable local laws. Our operating structure could make it difficult for us to coordinate procedures across our operations in a timely manner or at all. We may have difficulty attracting and retaining local personnel. In addition, our branches may require significant oversight and coordination from headquarters to support their growth. Inconsistent implementation of corporate strategy and policies at the local level could materially and adversely affect our overall profitability, prospects, business, results of operations, financial condition and cash flows. In addition, the operating results of an individual branch may differ from that of another branch for a variety of reasons, including market size, management practices, competitive landscape, regulatory requirements and local economic conditions. As a result, certain of our branches may experience higher or lower levels of growth than other branches.

16

Compliance with, or liabilities under, environmental, health and safety laws and regulations, including laws and regulations pertaining to the use and application of fertilizers, herbicides, insecticides and fungicides, could result in significant costs that adversely impact our reputation, business, financial position, results of operations and cash flows.

We are subject to 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, packaging, labeling, transportation, handling, treatment, storage, disposal and management of chemicals and hazardous substances and waste, and protect the health and safety of our associates and users of our products. Such laws also impose liability for investigating and remediating, and damages resulting from, present and past releases of hazardous substances, including releases at sites we have ever owned, leased or operated or used as a disposal site. We could be subject to fines, penalties, civil or criminal sanctions, personal injury, property damage or other third-party claims as a result of violations of, or liabilities under, these laws and regulations. We could also incur significant investigation and cleanup costs for contamination at any currently or formerly owned or operated facilities, including LESCO’s manufacturing and blending facilities. In addition, 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 that could have a material adverse effect on our business, financial position, results of operations and cash flows.

In addition, in the United States, products containing herbicides and pesticides generally must be registered with the U.S. Environmental Protection Agency (“EPA”) and similar state agencies before they can be sold or applied. The failure to obtain or the cancellation of any such registration, or the withdrawal from the marketplace of such products, could have an adverse effect on our business, the severity of which would depend in part on the products involved, whether other products could be substituted and whether our competitors were similarly affected. The herbicides and pesticides we use are manufactured by independent third parties and are evaluated by the EPA as part of its ongoing exposure risk assessment. The EPA may decide that a herbicide or pesticide we use will be limited or will not be re-registered for use in the United States. We cannot predict the outcome or the severity of the effect of the EPA’s continuing evaluations.

In addition, the use of certain herbicide and pesticide products is regulated by various federal, state, provincial and local environmental and public health agencies. We may be unable to prevent violations of these or other regulations from occurring. Even if we are able to comply with all such regulations and obtain all necessary registrations and licenses, the herbicides and pesticides or other products we supply could be alleged to cause injury to the environment, to people or to animals, or such products could be banned in certain circumstances. The regulations may also apply to customers who may fail to comply with environmental, health and safety laws and subject us to liabilities. Costs to comply with environmental, health and safety laws, or to address liabilities or obligations thereunder, could have a material adverse impact on our reputation, business, financial position, results of operations and cash flows.

Our business exposes us to risks associated with hazardous materials and related activities, not all of which are covered by insurance.

Because our business includes the managing, handling, storing, selling and transporting and disposing of certain hazardous materials, such as fertilizers, herbicides, pesticides, fungicides and rodenticides, we are exposed to environmental, health, safety and other risks. We carry insurance to protect us against many accident-related risks involved in the conduct of our business and we maintain insurance coverage in accordance with our assessment of the risks involved, the ability to bear those risks and the cost and availability of insurance. Each of these insurance policies is subject to exclusions, deductibles and coverage limits. We do not insure against all risks and may not be able to insure adequately against certain risks and may not have insurance coverage that will pay any particular claim. We also may be unable to obtain at commercially reasonable rates in the future adequate insurance coverage for the risks we currently insure against, and certain risks are or could become completely uninsurable or eligible for coverage only to a reduced extent. Our business, financial condition and results of operations could be materially impaired by environmental, health, safety and other risks that reduce our revenues, increase our costs or subject us to other liabilities in excess of available insurance.

Laws and government regulations applicable to our business could increase our legal and regulatory expenses, and impact our business, financial position, results of operations and cash flows.

Our business is subject to significant federal, state, provincial and local laws and regulations. These laws and regulations include laws relating to consumer protection, wage and hour requirements, the employment of immigrants, labor relations, permitting and licensing, building code requirements, workers’ safety, the environment, employee benefits, marketing and advertising and the application and use of herbicides, pesticides and other chemicals. In particular, we anticipate that various federal, state, provincial and local governing bodies may propose additional legislation and regulation that may be detrimental to our business, may decrease demand for the products we supply or may substantially increase our operating costs, including proposed legislation, such as environmental regulations related to chemical or nutrient use, water use, climate change, equipment efficiency standards and other environmental matters; other consumer protection laws or regulations; or health care coverage. It is difficult to predict the future impact of the broad and expanding legislative and regulatory requirements affecting our businesses and changes to such requirements may adversely affect our business, financial

17

position, results of operations and cash flows. In addition, if we were to fail to comply with any applicable law or regulation, we could be subject to substantial fines or damages, be involved in litigation, suffer losses to our reputation or suffer the loss of licenses or incur penalties that may affect how our business is operated, which, in turn, could have a material adverse impact on our business, financial position, results of operations and cash flows.

The nature of our business exposes us to construction defect and product liability claims as well as other legal proceedings.

We rely on manufacturers and other suppliers to provide us with the products we sell and distribute. As we do not have direct control over the quality of the products manufactured or supplied by such third-party suppliers, we are exposed to risks relating to the quality of the products we distribute. It is possible that inventory from a manufacturer or supplier could be sold to our customers and later be alleged to have quality problems or to have caused personal injury, subjecting us to potential claims from customers or third parties. We have been subject to such claims in the past, which have been resolved without material financial impact.

We operate a large fleet of trucks and other vehicles. From time to time, the drivers of these vehicles are involved in accidents which could result in material personal injuries and property damage claims and in which goods carried by these drivers may be lost or damaged.

We cannot make assurances that we will be able to obtain insurance coverage to address a portion of these types of liabilities on acceptable terms in the future, if at all, or that any such insurance will provide adequate coverage against potential claims. Further, while we seek indemnification against potential liability for products liability claims from relevant parties, including but not limited to manufacturers and suppliers, we do not have written indemnification agreements from all of our suppliers and we may be unable to recover under such indemnification agreements that exist. An unsuccessful product liability defense could be highly costly and accordingly result in a decline in revenues and profitability. Finally, even if we are successful in defending any claim relating to the products we distribute, claims of this nature could negatively impact customer confidence in our products and our company.

From time to time, we may be involved in government inquiries and investigations, as well as employment, tort proceedings, including toxic tort actions, and other litigation. We cannot predict with certainty the outcomes of these legal proceedings and other contingencies, including environmental investigation, remediation and other proceedings commenced by government authorities. The outcome of some of these legal proceedings and other contingencies could require us to take, or refrain from taking, actions which could adversely affect our operations or could require us to pay substantial amounts of money. Additionally, defending against lawsuits and proceedings may involve significant expense and diversion of management’s attention and resources from other matters regardless of the ultimate outcome.

We rely on our computer and data processing systems, and a large-scale malfunction or failure in our information technology systems could disrupt our business, create potential liabilities for us or limit our ability to effectively monitor, operate and control our operations and adversely impact our reputation, business, financial position, results of operations and cash flows.

Our ability to keep our business operating effectively depends on the functional and efficient operation of our enterprise resource planning, telecommunications, inventory tracking, billing and other information systems. We rely on these systems to track transactions, billings, payments and inventory, as well as to make a variety of day-to-day business decisions. We may experience system malfunctions, interruptions or security breaches from time to time. Our systems also run older generations of software that may be unable to perform as efficiently as, and fail to communicate well with, newer systems. We are in the process of upgrading our management information technology systems. As we implement or develop new systems in the future, we may elect to modify, replace or discontinue certain technology initiatives, which could result in write-downs, and changes or modifications to our information technology systems could cause disruptions to our operations or cause challenges with respect to our compliance with laws, regulations or other applicable standards.

A significant or large-scale malfunction, interruption or security breach of our systems could adversely affect our ability to manage and keep our operations running efficiently and damage our reputation. A malfunction that results in a wider or sustained disruption to our business could have a material adverse effect on our business, financial condition and results of operations, as well as on the ability of management to align and optimize technology to implement business strategies. A security breach might also lead to violations of privacy laws, regulations, trade guidelines or practices related to our customers and associates and could result in potential claims from customers, associates, shareholders or regulatory agencies. If our disaster recovery plans do not work as anticipated, or if any third-party vendors to which we have outsourced certain information technology or other services fail to fulfill their obligations to us, our operations may be adversely impacted and any of these circumstances could adversely impact our reputation, business, financial position, results of operations and cash flows.

18

If we fail to protect the security of personal information about our customers, we could be subject to interruption of our business operations, private litigation, reputational damage and costly penalties.

We rely on, among other things, commercially available systems, software, tools and monitoring to provide security for collecting, processing, transmitting and storing confidential customer information, such as payment card and personally identifiable information. The systems we currently use for payment card transactions, and the technology utilized in payment cards themselves, all of which can put payment card data at risk, are central to meeting standards set by the payment card industry, or PCI. We continue to evaluate and modify our systems and protocols for PCI compliance purposes; however PCI data security standards may change from time to time. Activities by third parties, advances in computer and software capabilities and encryption technology, new tools and discoveries and other events or developments may facilitate or result in a compromise or breach of our systems. Any compromises, breaches or errors in application related to our systems or failures to comply with data security standards set by the PCI could cause damage to our reputation and interruptions in our operations, including our customers’ ability to pay for our products and services by credit card or their willingness to purchase our products and services, and could further result in a violation of applicable laws, regulations, orders, industry standards or agreements and subject us to costs, penalties, litigation and liabilities which could have a material adverse impact on our reputation, business, financial position, results of operations and cash flows.

We may not be able to adequately protect our intellectual property and other proprietary rights that are material to our business.

Our ability to compete effectively depends in part on our rights to service marks, trademarks, trade names and other intellectual property rights we own or license, particularly our registered trademarks SiteOne^® and LESCO^®. We have not sought to register or protect every one of our marks or brand names either in the United States or in every country in which they are or may be used. Furthermore, because of the differences in foreign trademark, patent and other intellectual property or proprietary rights laws, we may not receive the same protection in other countries as we would in the United States. If we are unable to protect our proprietary information and brand names, we could suffer a material adverse impact on our reputation, business, financial position, results of operations and cash flows. Litigation may be necessary to enforce our intellectual property rights and protect our proprietary information, or to defend against claims by third parties that our products, services or activities infringe their intellectual property rights.

The requirements of being a public company, including compliance with the reporting requirements of the Exchange Act and the requirements of the Sarbanes-Oxley Act and the NYSE, may strain our resources, increase our costs and distract management, and we may be unable to comply with these requirements in a timely or cost-effective manner.

As a public company, we face significant legal, accounting, compliance and other expenses that we did not incur as a private company. We are obligated to file annual and quarterly information and other reports with the SEC, as required by the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and applicable SEC rules. We are also subject to other reporting and corporate governance requirements, including certain requirements of the NYSE, which impose significant compliance obligations upon us and increase our operating costs.

In addition, the Sarbanes-Oxley Act of 2002 and the Dodd-Frank Wall Street Reform and Consumer Protection Act, as well as rules subsequently implemented by the SEC and the NYSE, have imposed increased regulation and disclosure obligations and have required enhanced corporate governance practices of public companies. Our efforts to comply with evolving laws, regulations and standards are likely to result in increased administrative expenses and a diversion of management’s time and attention from sales-generating activities. If we do not comply with such requirements, we might be subject to sanctions or investigation by regulatory authorities, such as the SEC or the NYSE. Any such action could harm our reputation and the confidence of investors and could materially adversely affect our business and cause our stock price to decline.

These requirements also place additional demands on our finance and accounting staff and on our financial accounting and information systems. Other expenses associated with being a public company include increases in auditing, accounting and legal fees and expenses, investor relations expenses, increased directors’ fees and director and officer liability insurance costs, registrar and transfer agent fees and listing fees, as well as other expenses.

Any deficiencies in our financial reporting or internal controls could adversely affect our business and the trading price of our common stock.

As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in such internal controls. Section 404 of the Sarbanes-Oxley Act requires that we evaluate and determine the effectiveness of our internal control over financial reporting. Beginning with this Annual Report on Form 10-K (our second annual report following our initial public offering), we are required to provide a management report on internal control over financial reporting, which must be attested to by our independent registered public accounting firm.

19

Our current controls and any new controls that we develop may become inadequate because of changes in conditions in our business. Further, weaknesses in our disclosure controls and internal control over financial reporting may be discovered in the future. Any failure to maintain or develop effective controls or any difficulties encountered in their implementation or improvement could harm our operating results or cause us to fail to meet our reporting obligations and may result in a restatement of our financial statements for prior periods. Any failure to maintain effective internal control over financial reporting also could adversely affect the results of periodic management evaluations and annual independent registered public accounting firm attestation reports regarding the effectiveness of our internal control over financial reporting. Ineffective disclosure controls and procedures and internal control over financial reporting could also cause investors to lose confidence in our reported financial and other information, which would likely have a negative effect on the trading price of our common stock.

If we have a material weakness in our internal control over financial reporting, we may not detect errors on a timely basis and our financial statements may be materially misstated. In addition, our internal control over financial reporting may not prevent or detect all errors and fraud. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud will be detected.

If there are material weaknesses or failures in our ability to meet any of the requirements related to the maintenance and reporting of our internal controls, investors may lose confidence in the accuracy and completeness of our financial reports, which in turn could cause the price of our common stock to decline. Moreover, effective internal controls are necessary to produce reliable financial reports and to prevent fraud. If we have deficiencies in our internal controls, it may negatively impact our business, results of operations and reputation. In addition, we could become subject to investigations by the NYSE, the SEC or other regulatory authorities, which could require additional management attention and which could adversely affect our business.

We may be subject to securities litigation, which is expensive and could divert management attention and resources from our business.

Our share price may be volatile and, in the past, companies that have experienced volatility in the market price of their stock have been subject to securities class action litigation. We may be the target of this type of litigation in the future. Litigation of this type could result in substantial costs and diversion of management’s attention and resources, which could adversely impact our business. Any adverse determination in litigation could also subject us to significant liabilities.

We may be subject to unanticipated changes in our tax provisions, including further changes to applicable U.S. tax laws.

In December 2017, the Tax Cuts and Jobs Act (the “2017 Tax Act”) was enacted. The 2017 Tax Act includes a number of changes to existing U.S. tax laws that impact us, most notably a reduction of the U.S. corporate income tax rate from 35% to 21%, which required us to re-measure certain deferred tax assets and liabilities in the reporting period in which the 2017 Tax Act was signed into law, a one-time transition tax on certain foreign earnings that were previously deferred, and immediate expensing for certain assets placed into service after September 27, 2017. We recognized the income tax effects of the 2017 Tax Act in our 2017 financial statements in accordance with Staff Accounting Bulletin No. 118, which provides SEC staff guidance for the application of Accounting Standards Codification (“ASC”) Topic 740, Income Taxes. At December 31, 2017, we have not completed the accounting for the tax effects of enactment of the 2017 Tax Act. In certain instances, however, we have made a reasonable estimate (provisional amount) of the effects on our existing deferred tax balances and one-time transition tax. In other cases, we have not been able to make a reasonable estimate and continue to account for those items based on our existing accounting under ASC Topic 740, and the provisions of the tax laws that were in effect prior to enactment. In all cases, we will continue to make and refine our calculations as additional analysis is completed, and our provisional estimates may also be affected as we gain a more thorough understanding of the 2017 Tax Act.

Risks Related to Our Indebtedness

We have substantial indebtedness and may incur substantial additional indebtedness, which could adversely affect our financial health and our ability to obtain financing in the future, react to changes in our business or satisfy our obligations.

As of December 31, 2017 we had $476.1 million aggregate principal amount of total long-term consolidated indebtedness outstanding and $11.7 million of capital leases.

SiteOne Landscape Supply Holding, LLC (“Landscape Holding”) and SiteOne Landscape Supply, LLC (“Landscape”) are parties to a credit agreement dated December 23, 2013, which has been amended pursuant to Amendment No. 1 dated June 13, 2014, Amendment No. 2 dated January 26, 2015, Amendment No. 3 dated February 13, 2015 and Amendment No. 4 dated October 20, 2015 (such agreement, as so amended, the “ABL Credit Agreement”), providing for an asset-based loan facility in the amount of up to $325.0 million, subject to availability under a borrowing base, with UBS AG, Stamford Branch, as administrative agent and collateral agent, and the other financial institutions and lenders from time to time party thereto (the “ABL Facility”).

20

Landscape Holding and Landscape are parties to an amended and restated credit agreement dated April 29, 2016, providing for a senior secured term loan facility with UBS AG, Stamford Branch, as administrative agent and collateral agent, and the other financial institutions and lenders from time to time party thereto (as amended by the First Amendment to Amended and Restated Credit Agreement, dated as of November 23, 2016, and the Second Amendment to Amended and Restated Credit Agreement, dated as of May 24, 2017, and as further amended, supplemented, waived or otherwise modified from time to time, the “Term Loan Facility” and, together with the ABL Facility, the “Credit Facilities”) with the maturity date of April 29, 2022. On December 12, 2017, the Term Loan Facility was amended to, among other things, (i) add an additional credit facility under the Term Loan Facility consisting of additional term loans (the “Tranche D Term Loans”) in an aggregate principal amount of $298.0 million and (ii) increase the aggregate principal amount of Tranche D Term Loans under the Term Loan Facility to $350.0 million. Proceeds of the Tranche D Term Loans were used to, among other things, repay approximately $50.7 million of borrowings outstanding under the ABL Facility. See Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations-Term Loan Facility Amendments.”

In addition, we are able to incur additional indebtedness in the future, subject to the limitations contained in the agreements governing our indebtedness. Our substantial indebtedness could have important consequences. Because of our substantial indebtedness:

• our ability to engage in acquisitions without raising additional equity or obtaining additional debt financing is limited;

• our ability to obtain additional financing for working capital, capital expenditures, acquisitions, debt service requirements or general corporate purposes and our ability to satisfy our obligations with respect to our indebtedness may be impaired in the future;

• a large portion of our cash flow from operations must be dedicated to the payment of principal and interest on our indebtedness, thereby reducing the funds available to us for other purposes;

• we are exposed to the risk of increased interest rates because borrowings under the Credit Facilities and certain floating rate operating and capital leases are at variable rates of interest;

• it may be more difficult for us to satisfy our obligations to our creditors, resulting in possible defaults on, and acceleration of, such indebtedness;

• we may be more vulnerable to general adverse economic and industry conditions;

• we may be at a competitive disadvantage compared to our competitors with proportionately less indebtedness or with comparable indebtedness on more favorable terms and, as a result, they may be better positioned to withstand economic downturns;

• our ability to refinance indebtedness may be limited or the associated costs may increase;

• our flexibility to adjust to changing market conditions and ability to withstand competitive pressures could be limited; and

• we may be prevented from carrying out capital spending and restructurings that are necessary or important to our growth strategy and efforts to improve operating margins of our businesses.

Increases in interest rates would increase the cost of servicing our indebtedness and could reduce our profitability.

Our indebtedness under the Credit Facilities bears interest at variable rates, and as a result, increases in interest rates would increase the cost of servicing our indebtedness and could materially reduce our profitability and cash flows. As of December 31, 2017 each one percentage point change in interest rates would result in an approximately $1.3 million change in the annual interest expense on the amount outstanding under the ABL Facility. As of December 31, 2017, each one percentage point change in interest rates would result in an approximately $3.5 million change in the annual interest expense on the Term Loan Facility. The impact of increases in interest rates could be more significant for us than it would be for some other companies because of our substantial indebtedness.

A lowering or withdrawal of the ratings, outlook or watch assigned to our debt securities by rating agencies may increase our future borrowing costs and reduce our access to capital.

The ratings, outlook or watch assigned to our indebtedness could be lowered or withdrawn entirely by a rating agency if, in that rating agency’s judgment, current or future circumstances relating to the basis of the rating, outlook, or watch such as adverse changes to our business, so warrant. Based on the financial performance of our businesses and the outlook for future years, our credit ratings, outlook or watch could be negatively impacted. Any lowering of our ratings, outlook or watch likely would make it more difficult or more expensive for us to obtain additional debt financing.

The agreements and instruments governing our indebtedness contain restrictions and limitations that could significantly impact our ability to operate our business.

Our Credit Facilities contain customary representations and warranties and customary affirmative and negative covenants that restrict some of our activities. The negative covenants limit the ability of Landscape Holding and Landscape to:

• incur additional indebtedness;

• pay dividends, redeem stock or make other distributions;

• repurchase, prepay or redeem subordinated indebtedness;

21

• make investments;

• create restrictions on the ability of Landscape Holding’s restricted subsidiaries to pay dividends or make other intercompany transfers;

• create liens;

• transfer or sell assets;

• make negative pledges;

• consolidate, merge, sell or otherwise dispose of all or substantially all of Landscape Holding’s assets;

• enter into certain transactions with affiliates; and

• designate subsidiaries as unrestricted subsidiaries.

In addition, the ABL Facility is subject to various covenants requiring minimum financial ratios, and our additional borrowings may be limited by these financial ratios. Our ability to comply with the covenants and restrictions contained in the Credit Facilities, may be affected by economic, financial and industry conditions beyond our control including credit or capital market disruptions. The breach of any of these covenants or restrictions could result in a default that would permit the applicable lenders to declare all amounts outstanding thereunder to be due and payable, together with accrued and unpaid interest. If we are unable to repay indebtedness, lenders having secured obligations, such as the lenders under the Credit Facilities, could proceed against the collateral securing the indebtedness. In any such case, we may be unable to borrow under the Credit Facilities and may not be able to repay the amounts due under such facilities. This could have serious consequences to our financial position and results of operations and could cause us to become bankrupt or insolvent.

Our ability to generate the significant amount of cash needed to pay interest and principal on our indebtedness and our ability to refinance all or a portion of our indebtedness or obtain additional financing depends on many factors beyond our control.

Our ability to make scheduled payments on, or to refinance our obligations under, our indebtedness depends on the financial and operating performance of our subsidiaries, which, in turn, depends on their results of operations, cash flows, cash requirements, financial position and general business conditions and any legal and regulatory restrictions on the payment of dividends to which they may be subject, many of which may be beyond our control.

We may be unable to maintain a level of cash flows from operating activities sufficient to permit us to pay the principal and interest on our indebtedness. If our cash flow and capital resources are insufficient to fund our debt service obligations, we may be forced to reduce or delay capital expenditures, sell assets, seek to obtain additional equity capital or restructure our indebtedness. In the future, our cash flow and capital resources may not be sufficient for payments of interest on and principal of our indebtedness, and such alternative measures may not be successful and may not permit us to meet our scheduled debt service obligations.

The final maturity date of the ABL Facility is October 20, 2020. The final maturity date of the Term Loan Facility is April 29, 2022. We may be unable to refinance any of our indebtedness or obtain additional financing, particularly because of our high levels of indebtedness. Market disruptions, such as those experienced in 2008 and 2009, as well as our significant indebtedness levels, may increase our cost of borrowing or adversely affect our ability to refinance our obligations as they become due. If we are unable to refinance our indebtedness or access additional credit, or if short-term or long-term borrowing costs dramatically increase, our ability to finance current operations and meet our short-term and long-term obligations could be adversely affected.

Risks Related to Our Common Stock

Holdings is a holding company with no operations of its own, and it depends on its subsidiaries for cash to fund all of its operations and expenses, including to make future dividend payments, if any.

Our operations are conducted entirely through our subsidiaries, and our ability to generate cash to fund operations and expenses, to pay dividends or to meet debt service obligations is highly dependent on the earnings and the receipt of funds from our subsidiaries through dividends or intercompany loans. Deterioration in the financial condition, earnings or cash flow of Landscape and its subsidiaries for any reason could limit or impair their ability to pay such distributions. Additionally, to the extent that Holdings needs funds, and its subsidiaries are restricted from making such distributions under applicable law or regulation or under the terms of our financing arrangements, or are otherwise unable to provide such funds, it could materially adversely affect our business, financial condition, results of operations and cash flows.

Further, the terms of the agreements governing the Credit Facilities restrict the ability of our subsidiaries to pay dividends, make loans or otherwise transfer assets to Holdings. Furthermore, our subsidiaries are permitted under the terms of the Credit Facilities and other indebtedness to incur additional indebtedness that may restrict or prohibit the making of distributions, the payment of dividends or the making of loans by such subsidiaries to us. In addition, Delaware law may impose requirements that may restrict our ability to pay dividends to holders of our common stock.

22

We do not currently expect to declare or pay dividends on our common stock for the foreseeable future. Payments of dividends, if any, will be at the sole discretion of our board of directors after taking into account various factors, including general and economic conditions, our financial condition and operating results, our available cash and current and anticipated cash needs, capital requirements, contractual, legal, tax and regulatory restrictions and implications of the payment of dividends by us to our stockholders or by our subsidiaries (including Landscape) to us, and such other factors as our board of directors may deem relevant. In addition, Delaware law may impose requirements that may restrict our ability to pay dividends to holders of our common stock. To the extent that we determine in the future to pay dividends on our common stock, none of our subsidiaries will be obligated to make funds available to us for the payment of dividends.

The market price of our common stock may be volatile.

The market price of our common stock may fluctuate significantly. Among the factors that could affect our stock price are:

• industry or general market conditions;

• domestic and international economic factors unrelated to our performance;

• changes in our customers’ or their end-users’ preferences;

• new regulatory pronouncements and changes in regulatory guidelines;

• lawsuits, enforcement actions and other claims by third parties or governmental authorities;

• actual or anticipated fluctuations in our quarterly operating results;

• changes in securities analysts’ estimates of our financial performance;

• action by institutional stockholders or other large stockholders, including future sales;

• failure to meet any guidance given by us or any change in any guidance given by us, or changes by us in our guidance practices;

• announcements by us of significant impairment charges;

• speculation in the press or investment community;

• investor perception of us and our industry;

• changes in market valuations or earnings of similar companies;

• announcements by us or our competitors of significant contracts, acquisitions, dispositions or strategic partnerships;

• war, terrorist acts and epidemic disease;

• any future sales of our common stock or other securities; and

• additions or departures of key personnel.

In particular, we cannot assure that you will be able to resell your shares at or above your purchase price. The stock markets have experienced extreme volatility in recent years that has been unrelated to the operating performance of particular companies. These broad market fluctuations may adversely affect the trading price of our common stock. In the past, following periods of volatility in the market price of a company’s securities, class action litigation has often been instituted against the affected company. Any litigation of this type brought against us could result in substantial costs and a diversion of our management’s attention and resources, which would harm our business, results of operations, financial condition and cash flows.

Future sales of shares by us or our existing stockholders could cause our stock price to decline.

Sales of substantial amounts of our common stock in the public market, or the perception that these sales could occur, could cause the market price of our common stock to decline. These sales, or the possibility that these sales may occur, also might make it more difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate.

In the future, we may issue additional shares of common stock or other equity or debt securities convertible into common stock in connection with a financing, acquisition, litigation settlement or associate arrangement or otherwise. Any of these issuances could result in dilution to our existing stockholders and could cause the trading price of our common stock to decline.

Future offerings of debt or equity securities may adversely affect the market price of our common stock.

If, in the future, we decide to issue debt or equity securities that rank senior to our common stock, it is likely that such securities will be governed by an indenture or other instrument containing covenants restricting our operating flexibility. Additionally, any convertible or exchangeable securities that we issue in the future may have rights, preferences and privileges more favorable than those of our common stock and may result in dilution to owners of our common stock. We and, indirectly, our stockholders, will bear the cost of issuing and servicing such securities. Because our decision to issue debt or equity securities in any future offering will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing or nature of our future offerings. Thus, holders of our common stock will bear the risk of our future offerings reducing the market price of our common stock and diluting the value of their stock holdings in us.

23

Anti-takeover provisions in our amended and restated certificate of incorporation and amended and restated by-laws could discourage, delay or prevent a change of control of our company and may affect the trading price of our common stock.

Our amended and restated certificate of incorporation and second amended and restated by-laws, or amended and restated by-laws, include a number of provisions that may discourage, delay or prevent a change in our management or control over us that stockholders may consider favorable. For example, our amended and restated certificate of incorporation and amended and restated by-laws collectively:

• authorize the issuance of “blank check” preferred stock that could be issued by our board of directors to thwart a takeover attempt;

• provide for a classified board of directors, which divides our board of directors into three classes, with members of each class serving staggered three-year terms, which prevents stockholders from electing an entirely new board of directors at an annual meeting;

• limit the ability of stockholders to remove directors;

• provide that vacancies on our board of directors, including vacancies resulting from an enlargement of our board of directors, may be filled only by a majority vote of directors then in office;

• prohibit stockholders from calling special meetings of stockholders;

• prohibit stockholder action by written consent, thereby requiring all actions to be taken at a meeting of the stockholders;

• establish advance notice requirements for nominations of candidates for election as directors or to bring other business before an annual meeting of our stockholders; and

• require the approval of holders of at least 66 2⁄3% of the outstanding shares of our common stock to amend our amended and restated by-laws and certain provisions of our amended and restated certificate of incorporation.

These provisions may prevent our stockholders from receiving the benefit from any premium to the market price of our common stock offered by a bidder in a takeover context. Even in the absence of a takeover attempt, the existence of these provisions may adversely affect the prevailing market price of our common stock if the provisions are viewed as discouraging takeover attempts in the future.

Our amended and restated certificate of incorporation and amended and restated by-laws may also make it difficult for stockholders to replace or remove our management. Furthermore, the existence of the foregoing provisions could limit the price that investors might be willing to pay in the future for shares of our common stock. These provisions may facilitate management entrenchment that may delay, deter, render more difficult or prevent a change in our control, which may not be in the best interests of our stockholders.

We do not intend to pay dividends on our common stock and, consequently, your ability to achieve a return on your investment will depend on appreciation in the price of our common stock.

We do not intend to declare and pay dividends on our common stock for the foreseeable future. We currently intend to invest our future earnings, if any, to service our debt, to fund our growth, to develop our business, for working capital needs and for general corporate purposes. Therefore, you are not likely to receive any dividends on your common stock for the foreseeable future and the success of an investment in shares of our common stock will depend upon any future appreciation in their value. There is no guarantee that shares of our common stock will appreciate in value or even maintain the price at which our stockholders have purchased their shares. In addition, Holdings’ operations are conducted entirely through our subsidiaries. As such, to the extent that we determine in the future to pay dividends on our common stock, none of our subsidiaries will be obligated to make funds available to Holdings for the payment of dividends. Further, the agreements governing the Credit Facilities significantly restrict the ability of our subsidiaries to pay dividends or otherwise transfer assets to us.

Our amended and restated certificate of incorporation designates the Court of Chancery of the State of Delaware as the exclusive forum for certain litigation that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us.

Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware is, to the fullest extent permitted by law, the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed to us or our stockholders by any of our directors, officers, other employees, agents or stockholders, (iii) any action asserting a claim arising out of or under the General Corporation Law of the State of Delaware (the “DGCL”), or as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware (including, without limitation, any action asserting a claim arising out of or pursuant to our amended and restated certificate of incorporation or our amended and restated by-laws) or (iv) any action asserting a claim that is governed by the internal affairs doctrine. By becoming a stockholder in our company, you will be deemed to have notice of and have consented to the provisions of our amended and restated certificate of incorporation related to choice of forum. The choice of forum provision in our amended and restated certificate of incorporation may limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or any of our directors, officers, other employees, agents or stockholders, which may discourage lawsuits with respect to such claims. Alternatively, if a court were to find the choice of forum provision contained in our amended and restated certificate of incorporation to be inapplicable or unenforceable in an action, we

may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business, results of operations and financial condition.

A terrorist attack or the threat of a terrorist attack could have a material adverse effect on our business.

Discretionary spending on landscape projects is generally adversely affected during times of economic or political uncertainty. The potential for terrorist attacks, the national and international responses to terrorist attacks, and other acts of war or hostility could create these types of uncertainties and negatively impact our business for the short or long term in ways that cannot presently be predicted.

Item 3. Legal Proceedings

We are not currently involved in any material litigation or arbitration. We anticipate that we will be subject to litigation and arbitration from time to time in the ordinary course of business. At this time, we do not expect any of these proceedings to have a material effect on our reputation, business, financial position, results of operations and cash flows. However, we can give no assurance that the results of any such proceedings will not materially affect our reputation, business, financial position, results of operations and cash flows.

PART II

Item 5. Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

Common Stock Market Prices

Shares of our common stock have traded on the NYSE under the symbol “SITE” since May 12, 2016. Prior to that date, there was no market for our common stock. The range of high and low sale prices of our common stock as reported by the NYSE is set forth in the table below:

	High Sales Price		Low Sales Price
Fiscal Year 2016:
Second quarter (beginning May 12, 2016)	$	35.17	$	21.00
Third quarter	$	40.56	$	34.78
Fourth quarter	$	36.85	$	29.82
Fiscal Year 2017:
First quarter	$	48.41	$	35.72
Second quarter	$	53.18	$	46.24
Third quarter	$	58.10	$	48.40
Fourth quarter	$	76.70	$	58.95

Holders

As of February 20, 2018, there were four registered holders of our common stock. The actual number of holders of our common stock is greater than this number of record holders, and includes stockholders who are beneficial owners, but whose shares are held in street name by brokers or other nominees.

Dividends

On May 2, 2016, a one-time special cash dividend of $176.0 million was paid to existing stockholders of the Company as of April 29, 2016. Of the $176.0 million special cash dividend, $112.4 million was paid to holders of the Redeemable Convertible Preferred Stock (as defined below) in accordance with its right to participate in all distributions to common stockholders on an as-converted basis.

We do not expect to declare or pay dividends on our common stock for the foreseeable future. Instead, we intend to retain future earnings, if any, to service our debt, finance the growth and development of our business and for working capital and general corporate purposes. Our ability to pay dividends to holders of our common stock in the future will be limited as a practical matter by the Credit Facilities, insofar as we may seek to pay dividends out of funds made available to us by Landscape or its subsidiaries, because Landscape’s debt instruments directly or indirectly restrict Landscape’s ability to pay dividends or make loans to us. Any future determination to pay dividends on our common stock is subject to the discretion of our board of directors and will depend upon various factors, including our results of operations, financial condition, liquidity requirements, capital requirements, level of indebtedness, contractual restrictions with respect to payment of dividends, restrictions imposed by applicable law, general business conditions and other factors that our board of directors may deem relevant. See Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations-Liquidity and Capital Resources-Limitations of Distributions and Dividends by Subsidiaries” for a description of the restrictions on our ability to pay dividends.

Securities Authorized for Issuance Under Equity Compensation Plans

Stock Performance Graph

This performance graph shall not be deemed “soliciting material” or to be “filed” with the SEC for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (Exchange Act), or otherwise subject to the liabilities under that Section, and shall not be deemed to be incorporated by reference into any of our filings under the Securities Act of 1933, as amended, or the Exchange Act.

The graph below presents the Company’s cumulative total shareholder returns relative to the performance of the NYSE Composite Index, Standard & Poor's MidCap 400 Index and Dow Jones US Industrial Supplier Index for the period commencing on May 12, 2016 (the Company’s initial day of trading) and ending on December 31, 2017, the end of our last fiscal year. All values assume a $100 initial investment at the opening price of the Company’s common stock on the NYSE and data for the NYSE Composite Index, Standard & Poor's MidCap 400 Index and Dow Jones US Industrial Supplier Index assumes all dividends were reinvested on the date paid. The points on the graph represent fiscal quarter-end values based on the last trading day of each fiscal quarter. The comparisons are based on historical data and are not indicative of, nor intended to forecast, the future performance of our common stock.

Recent Sales of Unregistered Securities

On May 16, 2016, we issued 25,303,164 shares of our common stock to CD&R Landscapes Holdings, L.P. in exchange for the Preferred Stock then held by CD&R Landscapes Holdings, L.P., in accordance with the terms of the Preferred Stock. Such issuance was deemed to be exempt from registration under the Securities Act in reliance upon Section 3(a)(9) of the Securities Act, as any security exchanged by the issuer with its existing security holders exclusively where no commission or other remuneration is paid or given directly or indirectly for soliciting such exchange. There were no underwriters employed in connection with such issuance.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following information should be read in conjunction with the “Selected Financial Data” and the accompanying consolidated financial statements and related notes included in this Annual Report on Form 10-K.

The following discussion may contain forward-looking statements that reflect our plans, estimates and beliefs. Our actual results could differ materially from those discussed in these forward-looking statements. Factors that could cause or contribute to these differences include those factors discussed below and elsewhere in this Annual Report on Form 10-K, particularly in “Special Note Regarding Forward-Looking Statements and Information” and “Risk Factors” included elsewhere in this Annual Report on Form 10-K.

Overview

SiteOne Landscape Supply, Inc. (collectively with all its subsidiaries referred to in this Annual Report on Form 10-K as “SiteOne,” the “Company,” “we,” “us” and “our”) indirectly owns 100% of the membership interest in SiteOne Landscape Supply Holding, LLC (“Landscape Holding”). Landscape Holding is the parent and sole owner of SiteOne Landscape Supply, LLC (“Landscape”).

We are the largest and only national wholesale distributor of landscape supplies in the United States and have a growing 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. Through our expansive North American network of 511 branch locations in 45 states and six provinces, we offer a comprehensive selection of more than 120,000 SKUs, including fertilizer and control products (e.g., herbicides), irrigation supplies, landscape accessories, nursery goods, hardscapes (including paving, natural stone and blocks) and outdoor lighting. We also provide complementary, value-added consultative services to support our product offerings and to help our customers operate and grow their businesses.

CD&R Acquisition

Holdings indirectly owns 100% of the membership interest in Landscape Holding. Landscape Holding is the parent and sole owner of Landscape. Prior to the CD&R Acquisition described below, Deere was the sole owner of Landscape Holding.

On December 23, 2013, the Company acquired 100% of the ownership interest in Landscape Holding from Deere in exchange for common shares of the Company initially representing 40% of the outstanding capital stock (on an as-converted basis) plus cash consideration of approximately $314 million, net of pre-closing and post-closing adjustments. In order to facilitate the transaction, the Company issued cumulative convertible participating redeemable preferred stock to CD&R for total consideration of $174 million initially representing 60% of the outstanding capital stock (on an as-converted basis). As part of the same transaction, Landscape Holding also acquired from LESCO, an affiliate of Deere. The Company continues to be the sole owner of Landscape Holding.

Initial Public Offering

On May 17, 2016, we completed the IPO at a price to the public of $21.00 per share. In connection with the IPO, the CD&R Investor and Deere together sold an aggregate of 11,500,000 shares of common stock. The CD&R Investor and Deere received all of the net proceeds and bore all commissions and discounts from the sale of our common stock. We did not receive any proceeds from the IPO. On the day prior to the closing of the IPO, all of our then-outstanding Preferred Stock converted into shares of common stock, resulting in the issuance by us of an additional 25,303,164 shares of our common stock. The conversion of Preferred Stock is accounted for from the date of conversion and is not retroactively adjusted in our financial statements and related notes included in this Annual Report on Form 10-K.

Secondary Public Offerings

On December 5, 2016, certain selling stockholders completed a public offering of 10,350,000 shares of our common stock at a price of $33.00 per share. We did not receive any of the proceeds from the shares of common stock sold by the selling stockholders.

On May 1, 2017, certain selling stockholders completed a public offering of 11,500,000 shares of our common stock at a price of $47.50 per share. We did not receive any of the proceeds from the shares of common stock sold by the selling stockholders.

On July 26, 2017, certain selling stockholders completed a public offering of 5,437,502 shares of our common stock at a price to the underwriter of $51.63 per share. We did not receive any proceeds from the shares of common stock sold by the selling stockholders.

33

Following consummation of the secondary offering on July 26, 2017, CD&R and Deere no longer have an ownership interest in the Company.

Presentation

Our financial statements included in this report have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”). We use a 52/53 week fiscal year with the fiscal year ending on the Sunday nearest to December 31 in each year. Our fiscal quarters end on the Sunday nearest to March 31, June 30 and September 30, respectively.

This discussion of our financial condition is presented for the 2017 Fiscal Year, which ended on December 31, 2017 and included 52 weeks and 252 Selling Days, the 2016 Fiscal Year, which ended on January 1, 2017 and included 52 weeks and 253 Selling Days, and the 2015 Fiscal Year, which ended on January 3, 2016 and included 53 weeks and 256 Selling Days. “Selling Days” are defined below within the Key Business and Performance Metrics section.

We manage our business as a single reportable segment. Within our organizational framework, the same operational resources support multiple geographic regions and performance is evaluated at a consolidated level. We also evaluate performance based on discrete financial information on a regional basis. Since all of our regions have similar operations and share similar economic characteristics, we aggregate regions into a single operating and reportable segment. These similarities include (1) long-term financial performance, (2) the nature of products and services, (3) the types of customers we sell to and (4) the distribution methods used.

Key Business and Performance Metrics

We focus on a variety of indicators and key operating and financial metrics to monitor the financial condition and performance of our business. These metrics include:

Net sales. We generate net sales primarily through the sale of landscape supplies, including irrigation systems, fertilizer & control products, landscape accessories, nursery goods, hardscapes and outdoor lighting to our customers who are primarily landscape contractors serving the residential and commercial construction sectors. Our net sales include billings for freight and handling charges, and commissions on the sale of control products that we sell as an agent. Net sales are presented net of any discounts, returns, customer rebates, and sales or other revenue-based tax.

Non-GAAP Organic Sales. In managing our business, we consider all growth, including the opening of new greenfield branches, to be organic growth unless it results from an acquisition. When we refer to Organic Sales growth, we include increases in growth from newly-opened greenfield branches and decreases in growth from closing existing branches but exclude increases in growth from acquired branches until they have been under our ownership for at least four full fiscal quarters at the start of the fiscal reporting period.

Non-GAAP Selling Days. Selling Days are defined as business days, excluding Saturdays, Sundays and holidays, that our branches are open during the year.  Depending upon the location and the season, our branches may be open on Saturdays and Sundays; however for consistency, those days have been excluded from the calculation of Selling Days.

Non-GAAP Organic Daily Sales. We define Organic Daily Sales as Organic Sales divided by the number of Selling Days in the relevant reporting period. We believe Organic Sales growth and Organic Daily Sales growth are useful measures for evaluating our performance as we may choose to open or close branches in any given market depending upon the needs of our customers or our strategic growth opportunities.

Cost of goods sold. Our cost of goods sold includes all inventory costs, such as purchase price paid to suppliers, net of any rebates received, as well as inbound freight and handling, and other costs associated with inventory. Our cost of goods sold excludes the cost to deliver the products to our customers through our branches, which is included in selling, general and administrative expenses. Cost of goods sold is recognized primarily using the first-in first-out method of accounting for the inventory sold.

Gross profit and gross margin. We believe that gross profit and gross margin are useful for evaluating our operating performance. We define gross profit as net sales less cost of goods sold, exclusive of depreciation. We define gross margin as gross profit divided by net sales.

Selling, general and administrative expenses (operating expenses). Our operating expenses are primarily comprised of selling, general and administrative costs, which include personnel expenses (salaries, wages, employee benefits, payroll taxes, stock compensation and bonuses), rent, fuel, vehicle maintenance costs, insurance, utilities, repairs and maintenance and professional fees. Operating expenses also include depreciation and amortization.

34

Non-GAAP Adjusted EBITDA. In addition to the metrics discussed above, we believe that Adjusted EBITDA is useful for evaluating our operating performance and efficiency of our business. EBITDA represents our net income (loss) plus the sum of income tax (benefit), depreciation and amortization and interest expense, net of interest income. Adjusted EBITDA represents EBITDA as further adjusted for items such as stock-based compensation expense, related party advisory fees, loss (gain) on sale of assets, other non-cash items, other non-recurring (income) and loss. See “-Results of Operations-Quarterly Results of Operations Data” for more information about how we calculate EBITDA and Adjusted EBITDA and the limitations of those metrics.

Key Factors Affecting Our Operating Results

In addition to the metrics described above, a number of other important factors may affect our results of operations in any given period.

Weather Conditions and Seasonality

In a typical year, our operating results are impacted by seasonality. Historically, our net sales and net income have been higher in the second and third quarters of each fiscal year due to favorable weather and longer daylight conditions during these quarters. Our net sales have been significantly lower in the first and fourth quarters due to lower landscaping, irrigation and turf maintenance activities in these quarters, and we have historically incurred net losses in these quarters. Seasonal variations in operating results may also be significantly impacted by inclement weather conditions, such as snow storms and hurricanes, which not only impact the demand for certain products like fertilizer and ice melt but also may delay construction projects where our products are used.

Industry and Key Economic Conditions

Our business depends on demand from customers for landscape products and services. The landscape supply industry includes a significant amount of landscape products, such as irrigation systems, outdoor lighting, lawn care supplies, nursery goods and landscape accessories, for use in the construction of newly built homes, commercial buildings and recreational spaces. The landscape distribution industry has historically grown in line with rates of growth in residential housing and commercial building. The industry is also affected by trends in home prices, home sales and consumer spending. As general economic conditions improve or deteriorate, consumption of these products and services also tends to fluctuate. The landscape distribution industry also includes a significant amount of landscape products such as fertilizer, herbicides and ice melt for use in maintaining existing landscapes or facilities. The use of these products is also tied to general economic activity, but levels of sales are not as closely correlated to construction markets.

Popular Consumer Trends

Preferences in housing, lifestyle and environmental awareness can also impact the overall level of demand and mix for the products we offer. Examples of current trends we believe are important to our business include a heightened interest in professional landscape services inspired by the popularity of home and garden television shows and magazines; the increasingly popular concept of “outdoor living,” which has been a key driver of sales growth for our hardscapes and outdoor lighting products; and the social focus on eco-friendly products that promote water conservation, energy efficiency and the adoption of “green” standards.

Acquisitions

In addition to our organic growth we continue to grow our business through acquisitions in an effort to better service our existing customers and to attract new customers. These acquisitions have allowed us to further broaden our product lines and extend our geographic reach and leadership positions in local markets. In accordance with GAAP, the results of the acquisitions we have completed are reflected in our financial statements from the date of acquisition forward. We incur transaction costs in connection with identifying and completing acquisitions and ongoing integration costs as we integrate acquired companies and seek to achieve synergies. As of December 31, 2017, we have invested over $250 million in 18 acquisitions since the start of 2015 Fiscal Year, with the largest being the Shemin Nurseries investment of $57.7 million. The following is a summary of the acquisitions completed during the 2017, 2016 and 2015 Fiscal Years:

We expect the execution of synergistic acquisitions to continue to be an integral part of our growth strategy, and we intend to continue expanding our product line, geographic reach, market share and operational capabilities through future acquisitions.

Volume-Based Pricing

We generally procure our products through purchase orders rather than under long-term contracts 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 generally have annual supplier agreements, and while they generally do not provide for specific product pricing, many include volume-based financial incentives that we earn by meeting or exceeding target purchase volumes. Our ability to earn these volume-based incentives is an important factor in our financial results. In limited cases, we have entered into supply contracts with terms that exceed one year for the manufacture of our LESCO branded fertilizer and some nursery stock and grass seed, which may require us to purchase products in the future.

Strategic Initiatives

We continue to undertake operational initiatives, utilizing our scale to improve our profitability, enhance supply chain efficiency, strengthen our pricing and category management capabilities, streamline and refine our marketing process and invest in more sophisticated information technology systems and data analytics. We are increasingly focusing on our procurement and supply chain management initiatives to reduce sourcing costs. We are also implementing new inventory planning and stocking systems and evaluating ways to further improve the freight and logistics processes in an effort to reduce costs as well as improve our reliability and level of service. In addition, we work closely with our local branches to improve sales, delivery and branch productivity. We believe we will continue to benefit from the following initiatives, among others:

Pricing initiatives, including the development of a centralized pricing and discounting strategy and the implementation of data analytics to aid special pricing and bidding, were initiated beginning in the second quarter of 2015 and are expected to continue through 2019.

Category management initiatives, including the implementation of organic growth strategies, the development of our private label product strategy, the expansion of product lines, and the reorganization of brands and products by preferred suppliers, were initiated beginning in the first quarter of 2015 and are expected to continue through 2019.

Supply chain initiatives, including the implementation of new inventory planning and stocking systems, the installation of new distribution centers, local hubs in large markets, and local fleet utilization and cost improvement, were initiated in the fourth quarter of 2016 and are expected to continue through 2019.

Sales force performance initiatives, including the implementation of new compensation plans, the restructuring of our sales force, and the formal sales and product training for sales force and management, were initiated beginning in the third quarter of 2015 and are expected to continue through 2019.

Marketing initiatives, including a relaunch of the Partners Program and implementation of a digital marketing strategy, were initiated beginning in the third quarter of 2015 and are expected to continue through 2020.

E-commerce initiatives, including the relaunch of our website and the implementation of a B2B e-commerce platform, which provides the convenience of an online sales channel, enhanced account management functionality and industry specific productivity tools for our customers, are expected to continue through 2020.

Working Capital

In addition to affecting our net sales, fluctuations in prices of supplies tend to result in changes in our reported inventories, trade receivables and trade payables, even when our sales volumes and our rate of turnover of these working capital items remain relatively constant. Our business is characterized by a relatively high level of reported working capital, the effects of which can be compounded by changes in prices. Our working capital needs are exposed to these price fluctuations, as well as to fluctuations in our cost for transportation

37

and distribution. We might not always be able to reflect these increases in our pricing. The strategic initiatives described above are designed to reduce our exposure to these fluctuations and maintain and improve our efficiency.

Results of Operations

In the following discussion of our results of operations, we make comparisons among the 2017 Fiscal Year, the 2016 Fiscal Year and the 2015 Fiscal Year.

Comparison of the 2017 Fiscal Year to the 2016 Fiscal Year

Net sales

Net sales for the 2017 Fiscal Year increased 13% to $1,861.7 million as compared to $1,648.2 million for the 2016 Fiscal Year. Organic Daily Sales growth for 2017 Fiscal Year was 5%. Organic Daily Sales growth was driven by growth in the irrigation, nursery, landscape accessories, hardscapes and outdoor lighting categories, which together grew over 7% as the Company continued to benefit from strength in the construction and the repair and upgrade end markets. Organic Daily Sales for agronomic products increased 2% reflecting steady economic growth and strong sales to golf end market. Acquisitions contributed 8% or $135.0 million to net sales growth.

Costs of goods sold

Cost of goods sold for the 2017 Fiscal Year increased 12% to $1,266.2 million from $1,132.5 million for the 2016 Fiscal Year. The increase in cost of goods sold was primarily driven by the increased net sales growth, including acquisitions, partially offset by lower material cost, including manufacturing incentives.

Gross profit and gross margin

Gross profit for the 2017 Fiscal Year increased 15% to $595.5 million as compared to $515.7 million for the 2016 Fiscal Year. Gross profit growth was driven by the net sales increase resulting from Organic Sales growth and acquisitions in addition to margin expansion resulting from our operational initiatives. Gross margin increased 70 basis points to 32.0% in the 2017 Fiscal Year as compared to 31.3% in the 2016 Fiscal Year. Operational improvement in category management was the primary contributor to the growth. Product mix did not have a significant impact on gross margins. Acquisitions did not contribute to the margin improvement.

Selling, general and administrative expenses (operating expenses)

Operating expenses for the 2017 Fiscal Year increased 12% to $502.2 million from $446.5 million for the 2016 Fiscal Year. The increase in operating expenses was primarily driven by our growth from acquisitions. Operating expenses expressed as a percentage of net sales decreased to 27.0% for the 2017 Fiscal Year compared to 27.1% for the 2016 Fiscal Year. The decrease in operating expenses as a percentage of sales reflects non-recurrence of IPO related costs which occurred in the 2016 Fiscal Year partially offset by increased

38

investment in marketing, e-commerce and the sales force. Depreciation and amortization increased $6.1 million to $43.1 million primarily as result of our acquisitions.

Interest expense and other non-operating (income) expense

Interest expense and other non-operating (income) expense increased $3.1 million to $25.2 million in the 2017 Fiscal Year from $22.1 million in the 2016 Fiscal Year. The increase in interest expense was principally driven by the higher debt levels resulting from the refinancing of the Term Loan Facility in the 2016 Fiscal Year and the acquisition investments in the 2017 Fiscal Year.

Income tax (benefit) expense

Income tax expense was $18.0 million during the 2017 Fiscal Year as compared to income tax expense of $21.3 million during the 2016 Fiscal Year. The effective tax rate was 24.8% during the 2017 Fiscal Year as compared to 41.0% for the 2016 Fiscal Year.  The decrease in the effective tax rate was due primarily to (i) the adoption of ASU 2016-09 in the first quarter of 2017, which resulted in the recognition of excess tax benefits as a reduction of Income tax expense in the Company’s Consolidated Statements of Operations, and (ii) the December 2017 enactment of the Tax Cuts and Jobs Act (the “2017 Tax Act”). The 2017 Tax Act includes a number of changes to existing U.S. tax laws, most notably a reduction of the U.S. corporate income tax rate from 35% to 21%, which required us to re-measure certain deferred tax assets and liabilities in the reporting period in which the 2017 Tax Act was signed into law, and a one-time transition tax on certain foreign earnings that were previously deferred.

Net income

Net income for the 2017 Fiscal Year increased 78% to $54.6 million as compared to $30.6 million for the 2016 Fiscal Year. The increase in net income was primarily attributable to our lower effective tax rate, growth in sales both organically and through acquisitions, and the expansion of gross margin resulting from operational improvements.

Comparison of the 2016 Fiscal Year to the 2015 Fiscal Year

Net sales

Net sales for the 2016 Fiscal Year increased 14% to $1,648.2 million as compared to $1,451.6 million for the 2015 Fiscal Year. Organic Sales growth contributed 3% to overall growth, and acquisitions contributed an additional 11%. Net sales growth for the 2016 Fiscal Year, adjusted for one less week in the 2016 Fiscal Year compared to the 2015 Fiscal Year, would have been approximately one percentage point greater, or total net sales growth of 15% and Organic Sales growth of 4%. Organic Sales growth was driven by growth in the irrigation, nursery, landscape accessories, hardscapes and outdoor lighting categories, which together grew over 6% as a result of continued growth in residential and commercial construction. Organic Sales for fertilizer and control products decreased 2% reflecting modest market demand, fewer Selling Days, and the negative impact of branch consolidations. Acquisitions contributed $157.0 million to net sales growth.

Costs of goods sold

Cost of goods sold for the 2016 Fiscal Year increased 11% to $1,132.5 million from $1,022.5 million for the 2015 Fiscal Year. The increase in cost of goods sold was primarily driven by the increased net sales growth, including acquisitions, partially offset by lower material cost, including manufacturing incentives.

Gross profit and gross margin

Gross profit for the 2016 Fiscal Year increased 20% to $515.7 million as compared to $429.1 million for the 2015 Fiscal Year. Gross profit growth was driven by the net sales increase resulting from Organic Sales growth and acquisitions in addition to margin expansion resulting from our operational initiatives. Gross margin increased 170 basis points to 31.3% in the 2016 Fiscal Year as compared to 29.6% in the 2015 Fiscal Year. Operational improvements in pricing and category management were the primary contributors, each accounting for approximately half of the increase. Product mix did not have a significant impact on gross margins. Acquisitions contributed approximately 20 basis points to the margin improvement.

Selling, general and administrative expenses (operating expenses)

Operating expenses for the 2016 Fiscal Year increased 20% to $446.5 million from $373.3 million for the 2015 Fiscal Year. The increase in operating expenses was primarily driven by our growth from acquisitions. In addition, we incurred approximately $12.1 million in transition expenses related to our stock offerings, debt refinancing and subsequent amendment, and the termination of our

39

consulting agreements with CD&R and Deere. Operating expenses expressed as a percentage of net sales increased to 27.1% for the 2016 Fiscal Year compared to 25.7% for the 2015 Fiscal Year. The increase was driven primarily by the transition expenses discussed above, in addition to acquisitions and higher personnel costs to support our growth. Depreciation and amortization increased $5.8 million to $37.0 million primarily as result of our acquisitions.

Interest expense and other non-operating (income) expense

Interest expense and other non-operating (income) expense increased $10.7 million to $22.1 million in the 2016 Fiscal Year from $11.4 million in the 2015 Fiscal Year. The increase in interest expense was principally driven by the higher debt levels, a higher blended interest rate on our debt, and the write-off of unamortized debt discounts and issuance costs in connection with the refinancing and subsequent amendment transaction.

Income tax (benefit) expense

Income tax expense was $21.3 million during the 2016 Fiscal Year as compared to income tax expense of $19.5 million during the 2015 Fiscal Year. The effective tax rate was 41.0% during the 2016 Fiscal Year as compared to 40.3% for the 2015 Fiscal Year.  The increase in the effective tax rate was due primarily to nondeductible transaction costs related to our 2016 stock offerings.

Net income

Net income for the 2016 Fiscal Year increased 6% to $30.6 million as compared to $28.9 million for the 2015 Fiscal Year. The increase in net income was primarily attributable to the growth in sales both organically and through acquisitions, and the expansion of gross margin resulting from operational improvements, partially offset by increased operating expenses to support our sales growth and initiatives.

_____________________________________

(1) In addition to our net income (loss) determined in accordance with GAAP, we present Adjusted EBITDA in this Annual Report on Form 10-K to evaluate the operating performance and efficiency of our business. EBITDA represents our net income (loss) plus the sum of income tax (benefit), depreciation and amortization and interest expense, net of interest income. Adjusted EBITDA is further adjusted for stock-based compensation expense, related party advisory fees, loss (gain) on sale of assets, other non-cash items, other non-recurring (income) and loss. We believe that Adjusted EBITDA is an important supplemental measure of operating performance because:

• Adjusted EBITDA is used to test compliance with certain covenants under our long-term debt agreements;

• we believe Adjusted EBITDA is frequently used by securities analysts, investors and other interested parties in their evaluation of companies, many of which present an Adjusted EBITDA measure when reporting their results;

41

• we believe Adjusted EBITDA is helpful in highlighting operating trends, because it excludes the results of decisions that are outside the control of operating management and that can differ significantly from company to company depending on long-term strategic decisions regarding capital structure, the tax jurisdictions in which companies operate, age and book depreciation of facilities and capital investments;

• we consider (gains) losses on the acquisition, disposal and impairment of assets as resulting from investing decisions rather than ongoing operations; and

• other significant non-recurring items, while periodically affecting our results, may vary significantly from period to period and have a disproportionate effect in a given period, which affects comparability of our results.

Adjusted EBITDA is not a measure of our liquidity or financial performance under GAAP and should not be considered as an alternative to net income, operating income or any other performance measures derived in accordance with GAAP, or as an alternative to cash flow from operating activities as a measure of our liquidity. The use of Adjusted EBITDA instead of net income has limitations as an analytical tool. For example, this measure:

• does not reflect changes in, or cash requirements for, our working capital needs;

• does not reflect our interest expense, or the cash requirements necessary to service interest or principal payments, on our debt;

• does not reflect our income tax (benefit) expense or the cash requirements to pay our income taxes;

• does not reflect historical cash expenditures or future requirements for capital expenditures or contractual commitments; and

• although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and does not reflect any cash requirements for such replacements.

Management compensates for these limitations by relying primarily on our GAAP results and by using Adjusted EBITDA only as a supplement to provide a more complete understanding of the factors and trends affecting the business than GAAP results alone. Because not all companies use identical calculations, our presentation of Adjusted EBITDA may not be comparable to other similarly titled measures of other companies limiting their usefulness as a comparative measure.

The following table presents a reconciliation of Adjusted EBITDA to Net income (loss):

(a) Represents net sales from acquired branches that have not been under our ownership for at least four full fiscal quarters at the start of the 2017 Fiscal Year.

Liquidity and Capital Resources

Our ongoing liquidity needs are expected to be funded by cash on hand, net cash provided by operating activities and, as required, borrowings under the ABL Facility. We expect that cash provided from operations and available capacity under the ABL Facility will provide sufficient funds to operate our business, make expected capital expenditures, and meet our liquidity requirements for the following 12 months, including payment of interest and principal on our debt.

Our borrowing base capacity under the ABL Facility was $162.0 million as of December 31, 2017, after giving effect to approximately $127.0 million of revolving credit loans under the ABL Facility, a $36.0 million increase from $91.0 million of revolving credit loans as of January 1, 2017. As of December 31, 2017, we had total cash and cash equivalents of $16.7 million, total debt (net of debt discounts and issuance costs) of $463.6 million and capital leases of $11.7 million.

Working capital was $396.1 million as of December 31, 2017, an increase of $91.6 million as compared to $304.5 million as of January 1, 2017. The increase in working capital is attributable to growth in the business primarily through acquisitions.

Capital expenditures were $14.5 million for the 2017 Fiscal Year and represent an average of 0.8% net sales over the year. Capital expenditures have averaged $11.3 million annually from the 2015 Fiscal Year to the 2017 Fiscal Year and represent an average of 0.7% net sales over this time period.

Information about our cash flows, by category, is presented in our statements of cash flows and is summarized below:

	For the year
	January 2, 2017 to December 31, 2017			January 4, 2016 to January 1, 2017			December 29, 2014 to January 3, 2016
	(in millions)
Net cash provided by (used in):
Operating activities	$	16.3		$	72.9		$	71.0
Investing activities	$	(98.6	)	$	(74.9	)	$	(111.0	)
Financing activities	$	82.5		$	(1.8	)	$	49.7

Cash flow from operating activities

Cash flow from operating activities for the 2017 Fiscal Year was $16.3 million compared to $72.9 million for the 2016 Fiscal Year. The decrease in operating cash flow reflects increased working capital resulting from growth in our operations and transition to our new supply chain strategy.

Cash flow from operating activities for the 2016 Fiscal Year was $72.9 million compared to $71.0 million for the 2015 Fiscal Year. Cash flow from operations in the 2016 Fiscal Year benefited from our improvement in EBITDA resulting from our sales growth and operational initiatives.

Cash flow used in investing activities

Cash used in investing activities for the 2017 Fiscal Year was $98.6 million compared to $74.9 million in the 2016 Fiscal Year. Acquisition investment increased to $82.9 million in the 2017 Fiscal Year compared to 66.4 million the 2016 Fiscal Year, reflecting an increase in the number of transactions. Capital expenditures of $14.5 million were $5.7 million higher in the 2017 Fiscal Year compared to the 2016 Fiscal Year, driven primarily by investments in information technology and supply chain related to company initiatives.

Cash used in investing activities for the 2016 Fiscal Year was $74.9 million compared to $111.0 million in the 2015 Fiscal Year. The decrease reflects a lower investment in acquisitions during the 2016 Fiscal Year compared to the 2015 Fiscal Year primarily because we did not have an acquisition as large as the $57.7 million invested in Shemin Nurseries during the 2015 Fiscal Year. Capital expenditures of $8.8 million were also $1.7 million lower in the 2016 Fiscal Year compared to the 2015 Fiscal Year, driven primarily by the timing of investments in certain company initiatives.

Cash flow provided by (used in) financing activities

Cash flow from financing activities was $82.5 million for the 2017 Fiscal Year compared to cash used by financing activities of $1.8 million in the 2016 Fiscal Year. The increase in cash from financing activities was primarily attributable to increased borrowings to support our acquisition strategy.

Cash used in financing activities was $1.8 million for the 2016 Fiscal Year compared to cash provided by financing activities of $49.7 million in the 2015 Fiscal Year. The decrease in cash from financing activities was primarily driven by the lower investment in acquisitions. Cash used in financing activities for dividend payments was $189.0 million for the 2016 Fiscal Year due to a one-time special cash dividend of $176.0 million and preferred stock dividends of $13.0 million. During the 2015 Fiscal Year, the preferred stock dividends were paid in-kind and no dividends were paid in cash. Net cash provided by borrowings of $197.7 million in the 2016 Fiscal Year was primarily used to pay the dividends.

External Financing

Term Loan Facility

Landscape Holding and Landscape (collectively, the “Term Loan Borrower”) are parties to the Amended and Restated Term Loan Credit Agreement (the “Amended and Restated Term Loan Credit Agreement”) dated April 29, 2016, as amended on November 23, 2016, May 24, 2017 and December 12, 2017, with UBS AG, Stamford Branch as administrative agent and collateral agent, and the other financial institutions and lenders from time to time party thereto providing for a senior secured term loan facility in an aggregate principal amount of approximately $350.0 million (the “Term Loan Facility”). Landscape Holding and Landscape are the borrowers under the Term Loan Facility.

The final maturity date of the Term Loan Facility is April 29, 2022. In addition, however, the Amended and Restated Term Loan Credit Agreement provides the right for individual lenders to extend the maturity date of their loans upon the request of Landscape Holding without the consent of any other lender.

Subject to certain conditions, without the consent of the then existing lenders (but subject to the receipt of commitments), the Term Loan Facility may be increased (or a new term loan facility, revolving credit facility or letter of credit facility added) by up to (i) $100.0 million plus (ii) an additional amount that will not cause the net secured leverage ratio after giving effect to the incurrence of such additional amount and any use of proceeds thereof to exceed 3.50 to 1.00.

The Term Loan Facility is subject to mandatory prepayment provisions, covenants and events of default. Failure to comply with these covenants and other provisions could result in an event of default under the Term Loan Facility. If an event of default occurs, the lenders could elect to declare all amounts outstanding under the Term Loan Facility to be immediately due and payable and enforce their interest in collateral pledged under the agreement.

Refinancing

On April 29, 2016, we refinanced our then-existing term loan facility, or the “Prior Term Loan Facility,” with the Term Loan Facility. We refer to this refinancing transaction in this Annual Report as the “Refinancing.” We used borrowings under the Term Loan Facility to repay all $60.3 million of borrowings outstanding under the Prior Term Loan Facility, repay $29.9 million of borrowings outstanding under the ABL Facility, pay a special cash dividend of $176.0 million, or the “Special Cash Dividend,” to holders of our common stock and Preferred Stock as of April 29, 2016 and pay fees and expenses associated with the Refinancing.

Term Loan Facility Amendments

On November 23, 2016, we amended the Term Loan Facility (the “First Amendment”) to, among other things, (i) add the Tranche B Term Loans under the Term Loan Facility in an aggregate principal amount of $273.6 million and (ii) increase the aggregate principal amount of Tranche B Term Loans under the Term Loan Facility to $298.6 million pursuant to an increase supplement. Proceeds of the Tranche B Term Loans were used to, among other things, (i) repay in full the term loans outstanding under the Term Loan Facility immediately prior to effectiveness of the Term Loan Facility Amendments (the “Existing Term Loans”) and (ii) repay $21.0 million of borrowings outstanding under the ABL Facility.

On May 24, 2017, we amended the Term Loan Facility (the “Second Amendment”) to, among other things, add an additional credit facility under the Term Loan Facility consisting of additional term loans (the “Tranche C Term Loans”) in an aggregate principal amount of $299.5 million. Proceeds of the Tranche C Term Loans were used to, among other things, repay in full the Tranche B Term Loans outstanding under the Term Loan Facility immediately prior to effectiveness of the Second Amendment and pay fees and expenses associated with the transaction.

On December 12, 2017, we amended the Term Loan Facility (the “Third Amendment”) to, among other things, (i) add an additional credit facility under the Term Loan Facility consisting of additional term loans (the “Tranche D Term Loans”) in an aggregate principal amount of $298.0 million and (ii) increase the aggregate principal amount of Tranche D Term Loans under the Term Loan Facility to $350.0 million. Proceeds of the Tranche D Term Loans were used to, among other things, (i) repay in full the Tranche C Term Loans and (ii) repay approximately $50.7 million of borrowings outstanding under the ABL Facility.

The Tranche D Term Loans bear interest, at Landscape Holding’s option, at either (i) an adjusted LIBOR rate plus an applicable margin equal to 2.75% or (ii) an alternative base rate plus an applicable margin equal to 1.75%. Voluntary prepayments of the Tranche D Term Loans are permitted at any time, in minimum principal amounts, without premium or penalty, subject to a 1.00% premium payable in connection with certain repricing transactions within the first six months after the date of the initial funding of the Tranche D Term

45

Loans. The other terms of the Tranche D Term Loans are generally the same as the terms applicable to the Existing Term Loans.The interest rate on the outstanding balance of the Term Loan Facility was 4.32% as of December 31, 2017.

The Term Loan Facility contains customary representations and warranties and customary affirmative and negative covenants. The negative covenants limit the ability of Landscape Holding and Landscape to:

• incur additional indebtedness;

• pay dividends, redeem stock or make other distributions;

• repurchase, prepay or redeem subordinated indebtedness;

• make investments;

• create restrictions on the ability of Landscape Holding’s restricted subsidiaries to pay dividends or make other intercompany transfers;

• create liens;

• transfer or sell assets;

• make negative pledges;

• consolidate, merge, sell or otherwise dispose of all or substantially all of Landscape Holding’s assets;

• conduct, transact, or otherwise engage in businesses or operations at Landscape Holding other than certain specified exceptions relating to its role as a holding company of Landscape and its subsidiaries;

• enter into certain transactions with affiliates; and

• designate subsidiaries as unrestricted subsidiaries.

ABL Facility

Landscape Holding and Landscape (collectively, the “ABL Borrower”) are parties to the Credit Agreement dated December 23, 2013, as amended by the First Amendment to the Credit Agreement, dated June 13, 2014, the Second Amendment to the Credit Agreement, dated January 26, 2015, the Third Amendment to the Credit Agreement, dated February 13, 2015 and the Fourth Amendment to the Credit Agreement, dated October 20, 2015, the “ABL Credit Agreement”) with UBS AG, Stamford Branch as administrative agent and collateral agent, and the other financial institutions and lenders from time to time party thereto, providing for an asset-based credit facility (the “ABL Facility”) of up to $325.0 million, subject to borrowing base availability. The ABL Facility is secured by a first lien on the inventory and receivables. The ABL Facility is guaranteed by Bidco. Availability is determined using borrowing base calculations of eligible inventory and receivable balances. The interest rate on the ABL Facility is LIBOR plus an applicable margin ranging from 1.25% to 2.00% or an alternate base rate for U.S. dollar-denominated borrowings plus an applicable margin ranging from 0.25% to 1.00%. The interest rates on outstanding balances range from 3.25% to 3.32% and 2.49% to 4.50% as of December 31, 2017 and January 1, 2017, respectively. Additionally, the ABL Borrower pays a 0.250% and 0.375% commitment fee on the unfunded amount of as of December 31, 2017 and January 1, 2017, respectively. As of December 31, 2017, the outstanding balance on the ABL Facility was $127.0 million. The ABL Facility matures on October 20, 2020.

The ABL Facility contains customary representations and warranties and customary affirmative and negative covenants. The negative covenants are limited to the following: limitations on indebtedness, dividends, distributions and other restricted payments, investments, acquisitions, prepayments or redemptions of indebtedness under the Term Loan Facility, amendments of the Term Loan Facility, transactions with affiliates, asset sales, mergers, consolidations and sales of all or substantially all assets, liens, negative pledge clauses, changes in fiscal periods, changes in line of business, and hedging transactions. The negative covenants are subject to customary exceptions and also permit the payment of dividends and distributions, investments, permitted acquisitions, payments or redemptions of indebtedness under the Term Loan Facility, asset sales and mergers, consolidations and sales of all or substantially all assets involving subsidiaries upon satisfaction of a “payment condition.” The payment condition is deemed satisfied upon 30-day specified excess availability and specified availability exceeding agreed upon thresholds and, in certain cases, the absence of specified events of default or known events of default and pro forma compliance with a consolidated fixed charge coverage ratio of 1.00 to 1.00.

Subject to certain conditions, without the consent of the then existing lenders (but subject to the receipt of commitments), the ABL Facility may be increased (or a new term loan facility added) by up to (i) $100.0 million plus (ii) an additional amount that will not cause the net secured leverage ratio after giving effect to the incurrence of such additional amount and any use of proceeds thereof to exceed 5.00 to 1.00.

There are no financial covenants included in the ABL Credit Agreement, other than a springing minimum consolidated fixed charge coverage ratio of at least 1.00 to 1.00, which is tested only when specified availability is less than 10.0% of the lesser of (x) the then applicable borrowing base and (y) the then aggregate effective commitments under the ABL Facility, and continuing until such time as specified availability has been in excess of such threshold for a period of 30 consecutive calendar days.

46

Failure to comply with the covenants and other provisions included in the ABL Credit Agreement could result in an event of default under the ABL Facility. If an event of default occurs, the lenders could elect to declare all amounts outstanding under the ABL Facility to be immediately due and payable, enforce their interest in collateral pledged under the agreement or restrict the borrowers’ ability to obtain additional borrowings thereunder.

Limitations on Distributions and Dividends by Subsidiaries

The ability of our subsidiaries to make distributions and dividends to us depends on their operating results, cash requirements and financial condition and general business conditions, as well as restrictions under the laws of our subsidiaries’ jurisdictions.

The agreements governing the Term Loan Facility and the ABL Facility restrict the ability of our subsidiaries to pay dividends, make loans or otherwise transfer assets to us. Further, our subsidiaries are permitted under the terms of the Term Loan Facility and the ABL Facility and other indebtedness to incur additional indebtedness that may restrict or prohibit the making of distributions, the payment of dividends or the making of loans to us.

Interest Rate Swaps

We utilize interest rate swap contracts to reduce our exposure to fluctuations in variable interest rates for future interest payments on our unsecured syndicated senior Term Loan Facility. In June 2017, we entered into two forward-starting interest rate swap contracts to convert the variable interest rate to a fixed interest rate on portions of the borrowings under the Term Loan Facility. The contracts become effective on March 11, 2019 and terminate on June 11, 2021.

We will recognize any differences between the variable interest rate payments and the fixed interest rate settlements from the swap counterparties as an adjustment to interest expense over the life of the swaps. We have designated these swaps as cash flow hedges and will record the changes in the estimated fair value of the swaps to Accumulated other comprehensive income(loss) on our Consolidated Balance Sheets. To the extent the interest rate swaps are determined to be ineffective, we will recognize the changes in the estimated fair value of the swaps in earnings.

Failure of the swap counterparties would result in the loss of any potential benefit to us under the swap agreements. In this case, we would still be obligated to pay the variable interest payments underlying the debt agreements. Additionally, failure of the swap counterparties would not eliminate our obligation to continue to make payments under the existing swap agreements if it continues to be in a net pay position.

(1) For additional information see “Note 7. Long-Term Debt” in the notes to the condensed consolidated financial statements. In addition, the table excludes the debt issuance costs and debt discounts of $12.5 million.

(2) The interest on long term debt includes payments for agent administration fees. Interest payments on debt are calculated for future periods using interest rates in effect as of December 31, 2017. Certain of these projected interest payments may differ in the future based on changes in floating interest rates or other factors and events, including our entry into the Term Loan Facility Amendments. The projected interest payments only pertain to obligations and agreements outstanding as of December 31, 2017. See “Note 7. Long-Term Debt” in the notes to the condensed consolidated financial statements for further information regarding our debt instruments.

47

(3) Capital leases consist primarily of leases for delivery vehicles.

(4) Purchase obligations include various commitments with vendors to purchase goods and services, primarily inventory as well as definitive agreements to acquire an entity or group of assets. These purchase obligations are generally cancelable, but we have no intent to cancel and incur a penalty for not meeting the minimum required purchases. In addition, this table excludes purchase obligations of acquisitions made since December 31, 2017.

Critical Accounting Policies and Estimates

Critical accounting policies are those that are both important to the accurate portrayal of a company’s consolidated financial statements and require subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain.

In order to prepare financial statements in accordance with GAAP, we make estimates and assumptions that affect the amounts reported in our financial statements and accompanying notes. Certain estimates are particularly sensitive due to their significance to the financial statements and the possibility that future events may be significantly different from our expectations.

We have identified the following accounting policies that require us to make the most subjective or complex judgments in order to fairly present our consolidated financial statements.

Revenue Recognition

We recognize revenue when the following four basic criteria are met: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services have been rendered; (3) the price to the buyer is fixed or determinable; and (4) collectability is reasonably assured.

Sales of products are recorded when the sales price is determinable and the risks and rewards of ownership are transferred to independent parties. This transfer occurs primarily when goods are picked up by a customer at the branch or when goods are delivered to a customer location. In all cases, when a sale is recorded by the Company, no significant uncertainty exists surrounding the purchaser’s obligation to pay.

Our net sales include billings for freight and handling charges and commissions on the sale of control products that we sell as an agent. Net sales are presented net of any discounts, returns, customer rebates and sales or other revenue-based tax. Provisions for returns are estimated and accrued at the time a sale is recognized. We make appropriate provisions based on experience for costs such as doubtful receivables and sales incentives. We also have entered into agency agreements with certain suppliers whereby we operate as a sales agent of those suppliers. The suppliers retain title to their merchandise until we sell it and determine the prices at which we can sell the suppliers’ merchandise. As such, we recognize these agency sales on a net basis and record only their product margin as commission revenue within net sales.

Sales Incentives

We offer certain customers rebates which are accrued based on sales volumes. In addition, we offer a points-based reward program whereby reward points can be redeemed for credit on account or merchandise (such as gift cards or vacation trips). We accrue a liability for this program based on sales volumes and an estimate of points that will be redeemed before expiration. Liabilities for these sales incentives are included in accrued liabilities.

Inventory Valuation

Product inventories represent one of our largest assets and are recorded at net realizable value. Our goal is to manage our inventory so that we minimize out of stock positions. To do this, we maintain an adequate inventory of more than 120,000 SKUs at each branch based on sales history. At the same time, we continuously strive to better manage our slower moving classes of inventory. We monitor our inventory levels by branch and record provisions for excess inventories based on slower moving inventory. We define potential excess inventory as the amount of inventory on hand in excess of the historical usage, excluding items purchased in the last three months. We then review our most recent history of sales and adjustments of such excess inventory and apply our judgment as to forecasted demand and other factors, including liquidation value, to determine the required adjustments to net realizable value. In addition, at the end of each year, we evaluate our inventory at each branch and write off and dispose of obsolete products. Our inventories are generally not susceptible to technological obsolescence.

48

During the year, we perform periodic cycle counts and write off excess or damaged inventory as needed. Prior to year-end, we take a physical inventory and record any necessary additional write-offs.

Acquisitions

From time to time we enter into strategic acquisitions in an effort to better service existing customers and to attain new customers. When we acquire a controlling financial interest in an entity or group of assets that are determined to meet the definition of a business, we apply the acquisition method described in ASC Topic 805, Business Combinations. In accordance with GAAP, the results of the acquisitions we have completed are reflected in our financial statements from the date of acquisition forward.

We allocate the purchase consideration paid to acquire the business to the assets and liabilities acquired based on estimated fair values at the acquisition date, with the excess of purchase price over the estimated fair value of the net assets acquired recorded as goodwill. If during the measurement period (a period not to exceed 12 months from the acquisition date) we receive additional information that existed as of the acquisition date but at the time of the original allocation described above was unknown to us, we make the appropriate adjustments to the purchase price allocation in the reporting period the amounts are determined.

Significant judgment is required to estimate the fair value of intangible assets and in assigning their respective useful lives. Accordingly, we typically engage third-party valuation specialists, who work under the direction of management, for more significant tangible and intangible assets. The fair value estimates are based on available historical information and on future expectations and assumptions deemed reasonable by management, but are inherently uncertain.

We typically use an income method to estimate the fair value of intangible assets, which is based on forecasts of the expected future cash flows attributable to the respective assets. Significant estimates and assumptions inherent in the valuations reflect a consideration of other marketplace participants, and include the amount and timing of future cash flows (including expected growth rates and profitability), a brand’s relative market position and the discount rate applied to the cash flows. Unanticipated market or macroeconomic events and circumstances may occur, which could affect the accuracy or validity of the estimates and assumptions.

Determining the useful life of an intangible asset also requires judgment. All of our acquired intangible assets (e.g., trademarks, customer relationships and non-compete arrangements) are expected to have finite useful lives. Our assessment as to whether trademarks have an indefinite life or a finite life is based on a number of factors including competitive environment, market share, brand history, underlying product life cycles, operating plans and the macroeconomic environment of the regions in which the brands are sold. Our estimates of the useful lives of finite-lived intangible assets are primarily based on these same factors.

The costs of finite-lived intangible assets are amortized to expense over their estimated lives. The value of residual goodwill is not amortized, but is tested at least annually for impairment as described in the following note.

Goodwill

Goodwill represents the acquired fair value of a business in excess of the fair values of tangible and identified intangible assets acquired and liabilities assumed. We test goodwill on an annual basis as of July fiscal month end and additionally if an event occurs or circumstances change that would indicate the carrying amount may be impaired.

The impairment test is a single-step process. The process requires the Company to estimate and compare the fair value of a reporting unit to its carrying amount, including goodwill. If the fair value exceeds the carrying amount, the goodwill is not considered impaired. To the extent a reporting unit’s carrying amount exceeds its fair value, the reporting unit’s goodwill is deemed impaired, and an impairment charge is recognized based on the excess of a reporting unit’s carrying amount over its fair value. Each of our reporting units’ fair value has substantially exceeded its carrying value at each test date.

Stock-Based Compensation

Stock compensation expense for common stock options is based on the estimated fair value on the grant date using the Black-Scholes option pricing model. With respect to the deferred stock units (“DSUs”) and restricted stock units (“RSUs”), grant date fair values are equal to the fair market value of the underlying stock on the date of grant. Stock compensation expense is recorded in selling, general and administrative expenses with a corresponding increase in stockholders’ equity and generally recognized straight-line over the vesting periods. We issue new shares of common stock upon exercise of stock options, vesting of RSUs and upon settlement of DSUs.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Quantitative and Qualitative Disclosures about Market Risk

The economy and its impact on discretionary consumer spending, labor wages, fuel, fertilizer and other material costs, home sales, unemployment rates, insurance costs, foreign exchange and medical costs could have a material adverse impact on future results of operations.

We are aware of the potentially unfavorable effects inflationary pressures may create through higher asset replacement costs and related depreciation, higher interest rates and higher material costs.

Commodity Risk

Our operating performance may be affected by price fluctuations in commodity-based products like grass seed, fertilizer and glyphosate that we purchase and sell. We are also exposed to fluctuations in fuel costs as we deliver a substantial portion of the products we sell by truck. We seek to minimize the effects of inflation and changing prices through economies of purchasing and inventory management resulting in cost reductions and productivity improvements as well as price increases to maintain gross margins.

Product Price Risk

Our business model is to buy and sell at current market prices, in quantities approximately equal to estimated customer demand. We do not take significant “long” or “short” positions in the products we sell in an attempt to speculate on changes in product prices. Because we maintain inventories in order to serve the needs of our customers, we are subject to the risk of reductions in market prices for the products we hold in inventory, but we actively manage this risk by adjusting prices and managing our inventory levels.

Interest Rate Risk

We are subject to interest rate risk associated with our debt. While changes in interest rates do not affect the fair value of our variable-rate debt, they do affect future earnings and cash flows through higher interest expense. Interest rate swaps are entered into with the objective of converting variable to fixed rate debt, thereby reducing volatility in borrowing costs.

• The ABL Facility bears interest (i) in the case of U.S. dollar-denominated loans, either at LIBOR or the Prime Rate, at our option, plus applicable borrowing margins and (ii) in the case of Canadian dollar denominated loans, either at the Bankers’ Acceptances Rate or the Canadian Prime Rate, at our option, plus applicable borrowing margins. The borrowing margins are defined by a pricing grid, as included in the ABL Facility agreement, based on average excess availability for the previous quarter.

• The Term Loan Facility bears interest at LIBOR (subject to a floor of 1.00%) plus a borrowing margin of 2.75% or the Prime Rate plus a borrowing margin of 1.75% at the borrower’s election.

A 1% increase in interest rates on our variable-rate debt would increase our annual forecasted interest expense by approximately $4.8 million.

Credit Risk

We have a credit policy in place and monitor exposure to credit risk on an ongoing basis. We perform credit evaluations on all customers requesting credit above a specified exposure level. In the normal course of business, we provide credit to our customers, perform ongoing credit evaluations of these customers and maintain reserves for potential credit losses. Our typical credit terms extend 30 days from the date of purchase, but terms of up to 60 days are not uncommon. We typically have limited risk from a concentration of credit risk as no individual customer represents greater than 10% of the outstanding accounts receivable balance. Bad debt reserves, which we use as a proxy for our bad debt exposure, were 2.1% of gross receivables as of December 31, 2017.

Investments, if any, are only in liquid securities and only with counterparties with appropriate credit ratings. Transactions involving derivative financial instruments are with counterparties with which we have a signed netting agreement and which have appropriate credit ratings. We do not expect any counterparty to fail to meet its obligations.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the stockholders and the Board of Directors of SiteOne Landscape Supply, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of SiteOne Landscape Supply, Inc. and subsidiaries (the "Company") as of December 31, 2017 and January 1, 2017, the related consolidated statements of operations, comprehensive income, equity, and cash flows, for each of the three years in the period ended December 31, 2017, and the related notes and the schedule listed in the Index at Item 15 (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and January 1, 2017, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2017, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated December 31, 2017, expressed an unqualified opinion on the Company's internal control over financial reporting.

Basis for Opinion

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

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Notes to Consolidated Financial Statements

Note 1. Nature of Business and Significant Accounting Policies

Nature of business:

SiteOne Landscape Supply, Inc. is a supplier of irrigation supplies, fertilizer and control products, landscape accessories, nursery goods, hardscapes and outdoor lighting to green industry professionals. The Company also provides value-added consultative services to complement its product offering and to help customers operate and grow their businesses. Substantially all of SiteOne Landscape Supply, Inc.’s sales are to customers located in the United States of America (“U.S.”), with less than two percent of sales and total assets in Canada and other countries. As of December 31, 2017, the Company had over 475 branches. Based on the nature of SiteOne Landscape Supply, Inc.’s products and customers’ business cycles, sales are significantly higher in the spring and summer months.

Common Stock Split

On April 29, 2016, the Company filed a Certificate of Amendment to amend and restate the Company’s Certificate of Incorporation in the State of Delaware, effecting an 11.6181 for 1 common stock split. Each stockholder’s percentage ownership and proportional voting power remained unchanged as a result of the stock split. All applicable share data, per share amounts and related information in the consolidated financial statements and notes thereto have been adjusted retroactively to give effect to the 11.6181 for 1 common stock split.

Refinancing and Amendments of Term Loan and Special Cash Dividend

On April 29, 2016, the Company refinanced the existing term loan facility (the “Prior Term Loan Facility”) with an amended and restated $275.0 million term loan facility maturing in April 2022 (the “Term Loan Facility”). On April 29, 2016, the proceeds from the Term Loan Facility were used to repay all $60.3 million of borrowings outstanding under the Prior Term Loan Facility, to repay $29.9 million of borrowings outstanding under the senior asset-based credit facility (the “ABL Facility”), and to pay fees and expenses associated with the refinancing transaction.

On May 2, 2016, a one-time special cash dividend of $176.0 million was paid to existing holders of the Company’s common stock and cumulative convertible participating redeemable preferred stock (“Redeemable Convertible Preferred Stock”) as of April 29, 2016 out of the proceeds from the Refinancing of the Term Loan Facility. Of the $176.0 million paid to stockholders, $112.4 million was paid to holders of the Redeemable Convertible Preferred Stock in accordance with their right to participate in all distributions to common stockholders on an as-converted basis. The Redeemable Convertible Preferred Stock converted to common stock in accordance with its terms on May 16, 2016 resulting in the issuance by the Company of an additional 25,303,164 shares of its common stock which common shares are included in the weighted average common shares outstanding from that date forward. Prior to May 16, 2016, the Company’s earnings (loss) per share calculation reflected the impact of the Redeemable Convertible Preferred Stock. Since the special cash dividend was paid prior to conversion of the Redeemable Convertible Preferred Stock, the $112.4 million is reported as a reduction of net income attributable to common shares for the year ended January 1, 2017. In conjunction with the payment of the special cash dividend, the Company reduced the exercise price of certain outstanding options and made a cash payment of $2.8 million to certain holders of options to offset the dilutive impact of the special cash dividend.

On November 23, 2016, the Company amended the Term Loan Facility to, among other things, (i) add an additional credit facility under the Term Loan Facility consisting of additional term loans (the “Tranche B Term Loans”) in an aggregate principal amount of $273.6 million and (ii) increase the aggregate principal amount of Tranche B Term Loans under the Term Loan Facility to $298.6 million pursuant to an increase supplement. Proceeds of the Tranche B Term Loans were used to, among other things, (i) repay in full the term loans outstanding under the Term Loan Facility immediately prior to effectiveness of the Term Loan Facility Amendments (the “Existing Term Loans”) and (ii) repay $21.0 million of borrowings outstanding under the ABL Facility.

On May 24, 2017, the Company amended the Term Loan Facility (the “Second Amendment”) to, among other things, add an additional credit facility under the Term Loan Facility consisting of additional term loans (the “Tranche C Term Loans”) in an aggregate principal amount of $299.5 million. Proceeds of the Tranche C Term Loans were used to, among other things, repay in full the Tranche B Term Loans outstanding under the Term Loan Facility immediately prior to effectiveness of the Second Amendment and pay fees and expenses associated with the transaction.

On December 12, 2017, the Company amended the Term Loan Facility (the “Third Amendment”) to, among other things, (i) add an additional credit facility under the Term Loan Facility consisting of additional term loans (the “Tranche D Term Loans”) in an aggregate principal amount of $298.0 million and (ii) increase the aggregate principal amount of Tranche D Term Loans under the Term Loan

59

Facility to $350.0 million. Proceeds of the Tranche D Term Loans were used to, among other things, (i) repay in full the Tranche C Term Loans and (ii) repay approximately $50.7 million of borrowings outstanding under the ABL Facility.

Basis of financial statement presentation:

SiteOne Landscape Supply, Inc. (hereinafter, collectively with all its consolidated subsidiaries, referred to as the “Company” or individually as “Holdings”) indirectly owns 100% of the membership interest in SiteOne Landscape Supply Holding, LLC (referred to herein as “Landscape Holding”). Landscape Holding is parent and sole owner of SiteOne Landscape Supply, LLC (referred to herein as “Landscape”). Prior to the transaction described below, Deere & Company (“Deere”) was the sole owner of SiteOne Landscape Supply Holding, LLC.

On December 23, 2013 (the “Closing Date”), the Company acquired 100% of the ownership interest in Landscape Holding from Deere in exchange for common shares of the Company initially representing 40% of the outstanding capital stock (on an as-converted basis) plus cash consideration of approximately $314 million, net of pre-closing and post-closing adjustments. In order to facilitate the transaction, the Company issued cumulative convertible participating redeemable preferred stock (“Redeemable Convertible Preferred Stock”) to Clayton, Dubilier & Rice, LLC (“CD&R”) for total consideration of $174 million initially representing 60% of the outstanding capital stock (on an as-converted basis). As part of the same transaction, Landscape Holding also acquired from Deere the affiliated company LESCO, Inc. (“LESCO”). The Company continues to be the sole owner of Landscape Holding. The aforementioned transactions described in this paragraph are referred to herein as the “CD&R Acquisition”.

Following consummation of the secondary offering on July 26, 2017, CD&R and Deere no longer have an ownership interest in the Company.

60

The Company’s chief operating decision maker (“CODM”) manages the business as a single reportable segment. Within the organizational framework, the same operational resources support multiple geographical regions and performance is evaluated primarily by the CODM at a consolidated level. The CODM also evaluates regional performance based on financial and operational measures and receives discrete financial information on a regional basis. Since all of the Company’s regions have similar operations and share similar economic characteristics, the Company aggregates regions into a single operating and reportable segment. These similarities include 1) long-term financial performance, 2) the nature of products and services, 3) the types of customers the Company sells to and 4) the distribution methods used. Further, all of the Company’s product categories have similar supply chain processes, classes of customers and economic characteristics.

The accompanying audited financial statements of the Company included herein have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”).

The Consolidated Statements of Operations, Comprehensive income (loss), Equity and Cash Flows for the Company are presented for the fiscal years ended December 31, 2017, January 1, 2017 and January 3, 2016. The consolidated financial statements for the Company include the assets and liabilities used in operating the Company’s business, including entities in which the Company owns or controls more than 50% of the voting shares. The Company owns 100% of all subsidiaries presented in these financial statements. All intercompany balances and transactions have been eliminated in consolidation.

Significant accounting policies:

Use of estimates in the preparation of financial statements: The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Fiscal year: The Company’s fiscal year is a 52- or 53-week period ending on the Sunday nearest to December 31. The year ended December 31, 2017 includes 52 weeks. The year ended January 1, 2017 includes 52 weeks. The year ended January 3, 2016 includes 53 weeks.

Cash and cash equivalents: Cash and cash equivalents include primarily cash on deposit with banks which, at times, may exceed federally insured limits. The Company has not experienced any losses in these accounts. Cash and cash equivalents also include unsettled credit card transactions.

Accounts receivable: The Company carries accounts receivable at the original invoice amount less any charge-offs and the allowance for credit losses and doubtful accounts. Allowances for credit losses and doubtful accounts are maintained in amounts considered to be appropriate in relation to the receivables outstanding based on collection experience, economic conditions and credit risk quality. Receivables are written-off to the allowance when an account is considered uncollectible.

Activity in the allowance for doubtful accounts for the periods was as follows (in millions):

	For the year January 2, 2017 to December 31, 2017			For the year January 4, 2016 to January 1, 2017			For the year December 29, 2014 to January 3, 2016
Beginning balance	$	4.3		$	3.6		$	3.0
Provision (reduction) for allowance	2.0			1.1			1.0
Write-offs, net of recoveries	(1.6		)	(0.4		)	(0.4		)
Ending balance	$	4.7		$	4.3		$	3.6

Inventory: The majority of the Company’s inventories are valued at the lower of cost or net realizable value, with cost determined by the first-in, first-out (“FIFO”) method. Inventory is primarily considered to be finished goods. The Company establishes a reserve for excess, slow-moving, and obsolete inventory that is equal to the difference between the cost and estimated net realizable value for that inventory. These reserves are based on a review of planned and historical sales. The reserve for obsolete and excess inventory was approximately $5.1 million and $4.8 million as of December 31, 2017 and January 1, 2017, respectively.

Property and equipment, net: Property and equipment is stated at cost less accumulated depreciation. Depreciation is computed on property and equipment using the straight-line method over the estimated useful lives of the assets, as noted below. Leasehold improvements are depreciated over the lesser of their estimated useful lives or the remaining lease terms. Depreciation on property and equipment under

61

capital lease is included in depreciation expense. Expenditures for replacement or major renewals of significant items are capitalized. Expenditures for maintenance, repairs and minor renewals are generally charged to expense as incurred.

Asset Class	Estimated Useful Life
Buildings and improvements	20 years
Branch equipment	2 to 12 years
Furniture and fixtures	2 to 12 years
Auto and truck	2 to 6 years

Acquisitions: When the Company acquires a controlling financial interest in an entity or group of assets that are determined to meet the definition of a business, the acquisition method described in ASC Topic 805, Business Combinations, is applied. The Company allocates the purchase consideration paid to acquire the business to the assets and liabilities acquired based on estimated fair values at the acquisition date, with the excess of purchase price over the estimated fair value of the net assets acquired recorded as goodwill. If during the measurement period (a period not to exceed 12 months from the acquisition date) the Company receives additional information that existed as of the acquisition date but at the time of the original allocation described above was unknown, the Company makes the appropriate adjustment to the purchase price allocation in the reporting period in which the adjustment is identified.

Goodwill impairment: Goodwill represents the acquired fair value of a business in excess of the fair values of tangible and identified intangible assets acquired and liabilities assumed. The Company tests goodwill on an annual basis as of July fiscal month end and additionally if an event occurs or circumstances change that would indicate the carrying amount may be impaired. Examples of such indicators include a significant change in the business climate, unexpected competition, loss of key personnel or a decline in the Company’s market capitalization below the Company’s net book value. The Company performs impairment assessments at the reporting unit level, which is defined as an operating segment or one level below an operating segment, also known as a component.

With the issuance of Accounting Standards Update 2017-04 Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (“ASU 2017-04”) in January 2017, and adopted by the Company in July 2017 with its annual goodwill impairment test, the impairment test is now a single-step process. The process requires the Company to estimate and compare the fair value of a reporting unit to its carrying amount, including goodwill. If the fair value exceeds the carrying amount, the goodwill is not considered impaired. To the extent a reporting unit’s carrying amount exceeds its fair value, the reporting unit’s goodwill is deemed impaired, and an impairment charge is recognized based on the excess of a reporting unit’s carrying amount over its fair value.No impairment occurred during the periods presented. See Note 4 for a more detailed description of goodwill.

Intangible assets, net: Intangible assets include customer relationships, and trademarks and other, acquired through acquisitions. Intangibles assets with finite useful lives are amortized on an accelerated method or a straight-line of amortization over their estimated useful lives. An accelerated amortization method reflecting the pattern in which the asset will be consumed is utilized if that pattern can be reliably determined. If that pattern cannot be reliably determined, a straight-line amortization method is used. The Company considers the period of expected cash flows and underlying data used to measure the fair value of the intangible assets when selecting a useful life. Refer to Note 4 for a more detailed description of intangible asset amortization.

Impairment of Long-lived assets: Long-lived assets, primarily property and equipment, finite-lived intangible assets and long-term contracts included in other assets, are evaluated for impairment whenever events or changes in circumstances indicate the carrying value of an asset group may not be recoverable. The recoverability of an asset group is measured by a comparison of the carrying amount of the asset group to its future undiscounted cash flows.

If the recoverability test indicates the asset group balances are not recoverable, the Company would recognize an impairment charge to reduce the long-lived asset balances based on the fair value of the asset group. The amount of such impairment would be charged to operations in the current period. There were no impairment charges recognized during the years ended December 31, 2017, January 1, 2017 and January 3, 2016.

Fair value measurement: Fair value is defined as an exit price, representing an amount that would be received to sell an asset or the amount paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The inputs used to measure fair value are prioritized into the following three-tiered value hierarchy:

• Level 1: Unadjusted quoted prices in active markets for identical assets or liabilities.

62

• Level 2: Unadjusted quoted prices in active markets for similar assets or liabilities, unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active or inputs, other than quoted prices in active markets, which are observable either directly or indirectly.

• Level 3: Unobservable inputs for which there is little or no market data.

The hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. The classification of fair value measurement within the hierarchy is based upon the lowest level of input that is significant to the measurement.

The Company’s financial instruments consist of cash and cash equivalents, accounts receivables, forward-starting interest rate swap contracts and long-term debt. The variable interest rate on the long-term debt is reflective of current market borrowing rates. As such, the Company has determined that the carrying value of these financial instruments approximates fair value.

Interest Rate Swaps:

The Company utilizes interest rate swap contracts to reduce its exposure to fluctuations in variable interest rates for future interest payments on its syndicated senior Term Loan Facility. For determining the fair value of the interest rate swap contracts, the Company uses significant observable market data or assumptions (Level 2 inputs) that market participants would use in pricing similar assets or liabilities, including assumptions about counterparty risk. The fair value estimates reflect an income approach based on the terms of the interest rate swap contracts and inputs corroborated by observable market data including interest rate curves. The Company has designated these swaps as cash flow hedges, for which the Company records the effective portions of changes in their fair value, net of tax, in other comprehensive income (loss). To the extent the interest rate swaps are determined to be ineffective, the Company recognizes the changes in the estimated fair value of the swaps in earnings.

Revenue recognition: The Company recognize revenue when the following four basic criteria are met: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services have been rendered; (3) the price to the buyer is fixed or determinable; and (4) collectability is reasonably assured.

Sales of products are recorded when the sales price is determinable and the risks and rewards of ownership are transferred to independent parties. This transfer occurs primarily when goods are picked up by a customer at the branch or when goods are delivered to a customer location. In all cases, when a sale is recorded by the Company, no significant uncertainty exists surrounding the purchaser’s obligation to pay. Returns are estimated and accrued at the time a sale is recognized. The Company makes appropriate provisions based on experience for costs such as doubtful receivables and sales incentives. The Company also has entered into agency agreements with certain of its suppliers whereby the Company operates as a sales agent of those suppliers. The suppliers retain title to their merchandise until it is sold by the Company and determine the prices at which the Company can sell the suppliers’ merchandise. As such, the Company recognizes these agency sales on a net basis and records only the product margin as commission revenue within Net sales.

Sales incentives: The Company offers certain customers rebates which are accrued based on sales volumes. In addition, the Company offers a points-based reward program whereby reward points can be redeemed for merchandise or credit on account (such as gift cards or vacation trips). The Company accrues a liability for this program based on sales volumes and an estimate of points that will be redeemed before expiration. Liabilities for these sales incentives are included in Accrued Liabilities.

Sales taxes: The Company collects and remits taxes assessed by different governmental authorities that are both imposed on and concurrent with revenue producing transactions between the Company and its customers. These taxes may include sales, use, value-added and some excise taxes. The Company reports the collection of these taxes on a net basis (excluded from sales).

Cost of goods sold: Cost of goods sold includes all inventory costs, such as purchase price from suppliers, net of any rebates received, as well as inbound freight and handling, and other costs associated with the inventory and is exclusive of the cost to deliver the products to customers.

Shipping and handling costs: Shipping and handling costs associated with inbound freight are included in Cost of goods sold.

Warranty Reserves: Provisions for estimated warranty costs for the return of nursery product are provided for in the same period the related sales are recorded. The Company offers product warranties on selected nursery items. The warranty reserve is based on historical and current trends. The warranty reserve included in Accrued liabilities was approximately $0.5 million and $0.4 million as of December 31, 2017 and January 1, 2017, respectively.

Leases:The Company leases the majority of its facilities and enters into various other operating lease agreements in conducting its business. At the inception of each lease, the Company evaluates the lease agreement to determine whether the lease is an operating or capital lease. Operating lease expenses are recognized in the statements of operations on a straight-line basis over the term of the related lease. Some of the Company’s lease agreements may contain renewal options, tenant improvement allowances, rent holidays or rent

63

escalation clauses. When such items are included in a lease agreement, the Company records a deferred rent asset or liability on the consolidated balance sheets equal to the difference between the rent expense and cash rent payments.

The cost of property and equipment acquired under capital lease arrangements represents the lesser of the present value of the minimum lease payments or the fair value of the leased asset as of the inception of the lease.

Advertising costs: Advertising costs are charged to expense as incurred and were approximately $2.1 million, $0.9 million, and $0.4 million, during the years ended December 31, 2017, January 1, 2017 and January 3, 2016, respectively.

Stock-based compensation: The Company applies the fair value method to recognize compensation expense for stock-based awards. Using this method, the estimated grant-date fair value of the award is recognized on a straight-line basis over the requisite service period based on the portion of the award that is expected to vest.

Stock-based compensation expense for restricted stock units is measured based on the fair value of the Company’s common stock on the grant date. The Company utilizes the Black-Scholes option pricing model to estimate the grant-date fair value of option awards. The exercise price of option awards is set to equal the estimated fair value of the common stock at the date of the grant. The following weighted-average assumptions are also used to calculate the estimated fair value of option awards:

• Expected volatility: The expected volatility of the Company’s shares is estimated using the historical stock price volatility over the most recent period commensurate with the estimated expected term of the awards.

• Expected term: For employee stock option awards, the Company determines the weighted average expected term equal to the weighted period between the vesting period and the contract life of all outstanding options.

• Dividend yield: The Company has not paid dividends and does not anticipate paying a cash dividend in the foreseeable future and, accordingly, uses an expected dividend yield of zero.

• Risk-free interest rate: The Company bases the risk-free interest rate on the implied yield available on a U.S. Treasury note with a term equal to the estimated expected term of the awards.

Refer to Note 6 for further details regarding stock-based compensation.

Other income: Other income consists primarily of financing charges and net gain/loss on sale of assets.

Income taxes: The Company files a consolidated federal income tax return and files both combined or unitary state income tax returns as well as separate state income tax returns in certain jurisdictions.

Deferred taxes are provided on an asset and liability method in which deferred tax assets are recognized for deductible temporary differences and operating loss and tax credit carry forwards, and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax basis. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment. Realization of deferred tax assets is dependent upon sufficient future taxable income.

The Company’s operations involve dealing with uncertainties and judgments in the application of complex tax regulations in a multitude of jurisdictions. The Company reports a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return based on its estimate of whether, and the extent to which, additional taxes will be due. The Company recognizes interest, if any, related to unrecognized tax benefits within the Interest and other non-operating expenses line item, and recognizes penalties in Selling, general and administrative expenses.

In December 2017, the Tax Cuts and Jobs Act (the “2017 Tax Act”) was enacted. The 2017 Tax Act includes a number of changes to existing U.S. tax laws that impact the Company, most notably a reduction of the U.S. corporate income tax rate from 35% to 21%, which required the Company to re-measure certain deferred tax assets and liabilities in the reporting period in which the 2017 Tax Act was signed into law, a one-time transition tax on certain foreign earnings that were previously deferred, and immediate expensing for certain assets placed into service after September 27, 2017. The Company recognized the income tax effects of the 2017 Tax Act in its 2017 financial statements in accordance with Staff Accounting Bulletin No. 118, which provides SEC staff guidance for the application of ASC Topic 740, Income Taxes. At December 31, 2017, the Company has not completed its accounting for the tax effects of enactment of the 2017 Tax Act. In certain instances, however, the Company has made a reasonable estimate (provisional amount) of the effects with respect to existing deferred tax balances and the one-time transition tax. In other cases, the Company has not been able to make a

64

reasonable estimate and continues to account for those items based on existing accounting under ASC Topic 740, and the provisions of the tax laws that were in effect prior to enactment. In all cases, the Company will continue to make and refine its calculations as additional analysis is completed, and provisional estimates may also be affected as the Company gains a more thorough understanding of the 2017 Tax Act. See Note 8 for further information pertaining to income taxes.

Foreign currency translation: The functional currency for the Company’s Canadian operations is the Canadian dollar, the local currency. The assets and liabilities of these operations are translated into U.S. dollars at the end of the period exchange rates. The revenues and expenses are translated at average exchange rates for the period. The gains or losses from these translations are recorded in other comprehensive income (loss). Gains or losses recognized on transactions denominated in a currency other than the functional currency are included in net income (loss).

Beneficial conversion features: The Company had issued Redeemable Convertible Preferred Stock with dividends that were paid-in-kind during the years ended January 3, 2016 and December 28, 2014. The Company recorded paid-in-kind dividends at carrying value on the issuance date. The paid-in-kind dividends in the form of Redeemable Convertible Preferred Stock contained the same conversion rate as the Redeemable Convertible Preferred Stock issued on the Closing Date. For certain Redeemable Convertible Preferred Stock issued as dividends paid-in-kind, the stated conversion price was determined to be less than the common stock price as of the dividend payment date resulting in the recognition of a beneficial conversion feature (“BCF”) in additional paid-in capital. Since the Redeemable Convertible Preferred Stock did not have a fixed or determinable redemption date and was readily convertible at any time, the Company immediately amortized any BCF recognized through retained earnings. The Redeemable Convertible Preferred Stock converted to common stock in accordance to its terms on May 16, 2016.

Recently Issued and Adopted Accounting Pronouncements

In September 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-16, Business Combinations, an update to the existing guidance under the Business Combinations topic. This update simplifies the accounting for measurement-period adjustments. The amendments in this update require that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. This update will be effective for all annual and interim periods beginning after December 15, 2015. The amendments in this update should be applied prospectively to adjustments to provisional amounts that occur after the effective date of this update with earlier application permitted for financial statements that have not been issued. The adoption of this update did not have a material impact on the Company’s consolidated financial statements.

In July 2015, the FASB issued ASU 2015-11, “Inventory (Topic 330): Simplifying the Measurement of Inventory” (“ASU 2015-11”), which requires entities to measure inventory at the lower of cost or net realizable value rather than at the lower of cost or market. Net realizable value is defined as the estimated selling price in the ordinary course of business less reasonably predictable costs of completion, disposal and transportation. The Company adopted ASU 2015-11 when it became effective in the first quarter of the 2017 Fiscal Year. The adoption of ASU 2015-11 did not have a material impact on the Company’s consolidated financial statements.

In March 2016, the FASB issued ASU 2016-09, “Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting” (“ASU 2016-09”), which simplifies several aspects of the accounting for employee share-based payment transactions for both public and nonpublic entities, including the accounting for income taxes, forfeitures and statutory tax withholding requirements, as well as classification in the statement of cash flows. The Company adopted ASU 2016-09 when it became effective in the first quarter of the 2017 Fiscal Year on a prospective basis and as such, the Company’s prior year presentation has not changed. The primary impact of the adoption was the recognition of excess tax benefits as a reduction of Income tax expense on the Company’s Consolidated Statements of Operations. As a result, excess tax benefits of $6.8 million were recognized as a reduction of Income tax expense for the year ended December 31, 2017. Historically, these amounts were recorded as Additional paid-in capital in Stockholders’ equity on the Company’s Consolidated Balance Sheets. The Company also elected to adopt the cash flow presentation of the excess tax benefits prospectively commencing in the first quarter of 2017. The Company now presents excess tax benefits or tax deficiencies within operating cash flows versus financing activities on the Consolidated Statements of Cash Flows. Another impact of the adoption is that the calculation of the effect of dilutive securities now excludes any derived excess tax benefits or deficiencies from assumed future proceeds, resulting in an increase in diluted weighted average shares outstanding. Additionally, the Company elected to account for forfeitures of share-based payments as they occur and there was no material financial impact as a result. None of the other provisions in ASU 2016-09 had a material impact on the Company’s consolidated financial statements.

In January 2017, the FASB issued ASU 2017-04, “Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment” (“ASU 2017-04”), which eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge (also known as Step 2 under the current guidance). Rather, the measurement of a goodwill impairment charge will be based on the excess of a reporting unit’s carrying value over its fair value (Step 1 under the current guidance). ASU 2017-04 will be effective for annual and interim goodwill impairment tests performed in periods beginning after December 15, 2019 and should be applied

65

prospectively. Early adoption is permitted for annual and interim goodwill impairment tests beginning after January 1, 2017. The Company adopted ASU 2017-04 in July 2017 with its annual goodwill impairment test. The adoption of ASU 2017-04 did not have a material impact on the Company’s consolidated financial statements and related disclosures.

In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities” (“ASU 2017-12”), which seeks to improve the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements. Additionally, ASU 2017-12 makes certain targeted improvements to simplify the application of the hedge accounting guidance in current GAAP based on the feedback received from preparers, auditors, users, and other stakeholders. ASU 2017-12 adds new disclosure requirements, amends existing ones and removes the requirement for entities to disclose amounts of hedge ineffectiveness. In addition, an entity must now provide tabular disclosures about: both (i) the total amounts reported in the statement of financial performance for each income and expense line item that is affected by fair value or cash flow hedging and (ii) the effects of hedging on those line items; and the carrying amounts and cumulative basis adjustments of items designated and qualifying as hedged items in fair value hedges. Early adoption is permitted in any interim period after issuance of ASU 2017-12. The Company adopted ASU 2017-12 in the third quarter of the 2017 Fiscal Year. The adoption of ASU 2017-12 did not have a material impact on the Company’s consolidated financial statements.

Accounting Pronouncements Issued But Not Yet Adopted

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”), which amends existing revenue recognition standards and establishes a new Accounting Standards Codification (“ASC”) Topic 606. The core principle of this amendment is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for these goods or services. The Company has concluded that it will have substantially similar performance obligations under the amended guidance as compared with deliverables and units of account currently being recognized. Additionally, the Company has made policy elections within the amended standard that are consistent with its current accounting. The Company has evaluated the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures and controls. Based on its assessment, the Company has determined that the adoption of ASU 2014-09 will result in additional revenue recognition disclosures, and will have an immaterial impact on the timing of revenue recognition related to its incentive programs. The Company also evaluated other considerations within the guidance and concluded that there are no additional changes required with adopting ASU 2014-09. The Company will adopt ASU 2014-09 in the first quarter of 2018 using the modified retrospective transition method.

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” (“ASU 2016-02”), which amends the guidance for recognition, measurement, presentation and disclosures of lease arrangements and establishes a new ASC Topic 842. The amended standard will require recognition on the balance sheet for all leases with terms longer than 12 months as a lease liability and as a right-of-use asset. The lease liability is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis, and the right-of-use asset is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. The new standard requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. ASU 2016-02 is effective for the Company commencing in the first quarter of fiscal year 2019. The Company is currently evaluating the amended guidance and the impact on its consolidated financial statements and related disclosures.

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326) - Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”), which changes the way companies evaluate credit losses for most financial assets and certain other instruments. For trade and other receivables, held-to-maturity debt securities, loans and other instruments, entities will be required to use a new forward-looking “expected loss” model to evaluate impairment, potentially resulting in earlier recognition of allowances for losses. The new standard also requires enhanced disclosures, including the requirement to disclose the information used to track credit quality by year of origination for most financing receivables. ASU 2016-13 will be effective for the Company commencing in the first quarter of fiscal year 2020. The guidance must be applied using a cumulative-effect transition method. The Company is currently evaluating the amended guidance and the impact on its consolidated financial statements and related disclosures.

In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”), to provide clarification on cash flow classification related to eight specific issues including debt prepayment or debt extinguishment costs and contingent consideration payments made after a business combination. The guidance in ASU 2016-15 should be applied using a retrospective transition method to each period presented. ASU 2016-15 becomes effective for the Company in the first quarter of fiscal year 2018. The Company is currently evaluating the amended guidance and the impact on its consolidated financial statements and related disclosures.

In October 2016, the FASB issued ASU 2016-16, “Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory”(“ASU 2016-16”), which amends existing guidance to require entities to recognize income tax consequences of an intra-entity transfer of an asset, other than inventory, when the transfer occurs. ASU 2016-16 will be effective for the Company commencing in the

66

first quarter of fiscal year 2018 using a modified retrospective method. The Company is currently evaluating the impact of this amended guidance; however, the provisions of ASU 2016-16 are not expected to have a significant impact on the Company’s consolidated financial statements and related disclosures.

In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash” (“ASU 2016-18”), which requires restricted cash and restricted cash equivalents to be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. Transfers between cash and cash equivalents and restricted cash or restricted cash equivalents are not reported as cash flow activities in the statement of cash flows. ASU 2016-18 will be effective for the Company in the first quarter of fiscal year 2018, using a retrospective transition method. The Company is currently evaluating the amended guidance and the impact on its consolidated financial statements and related disclosures.

In January 2017, the FASB issued ASU 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business” (“ASU 2017-01”), to clarify the definition of a business to assist entities with evaluating whether transactions should be accounted for as acquisitions of assets or businesses. ASU 2017-01 provides a screen to determine when an integrated set of assets and activities (collectively a “set”) is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. If the screen is not met, ASU 2017-01 requires that to be considered a business, a set must include an input and a substantive process that together significantly contribute to the ability to create output. ASU 2017-01 will be effective for the Company in the first quarter of fiscal year 2018, and should be applied prospectively. The Company is currently evaluating the amended guidance; however, the provisions of ASU 2017-01 are not expected to have a material impact on the Company's consolidated financial statements and related disclosures.

In May 2017, the FASB issued ASU 2017-09, “Compensation-Stock Compensation (Topic 718) - Scope of Modification” (“ASU 2017-09”), which provides clarity and reduces both diversity in practice and cost and complexity when applying the guidance in Topic 718 when there are changes to the terms or conditions of a share-based payment award. The amendments in ASU 2017-09 provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. ASU 2017-09 will be effective for the Company in the first quarter of fiscal year 2018 on a prospective basis. The Company is currently evaluating the amended guidance and the impact on its consolidated financial statements and related disclosures.

These transactions were accounted for by the acquisition method, and accordingly the results of operations were included in the Company’s consolidated financial statements from their respective acquisition dates.

Shemin Acquisition Accounting:

The Shemin transaction has been accounted for as a business combination using the acquisition method of accounting, whereby the purchase price was allocated to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values at the acquisition date, with the excess of purchase price over the estimated fair value of the net assets acquired recorded as goodwill. Transaction related costs incurred in connection with the Shemin acquisition were approximately $2.7 million. These level 3 fair value measurements have been determined based on assumptions that market participants would use in the pricing of the asset or liability. Independent third-party appraisers were engaged under the direction of management to perform valuation of certain tangible and intangible assets acquired and liabilities assumed.

The real and personal property was valued using the cost, market and income approaches. The income approach was utilized to estimate the fair value of the lease interests via the discounted cash flow methodology. Personal property was valued using the indirect method of the cost approach and the market approach. Using the indirect approach a reproduction cost of new personal property was determined from the historical cost.

Intangible assets separately valued in the transaction were customer relationships. Customer relationships were valued using the discounted cash flow method form of the income approach. After tax cash flow was discounted to present value using a 16.0% discount rate. Revenue growth was estimated based on long-term growth rates. Annual attrition was estimated at 10.0%.

The following table summarized the adjusted aggregate fair values of the assets acquired and liabilities assumed at the acquisition date of February 27, 2015 and subsequent adjustments. The estimate of the fair values of assets acquired and liabilities assumed is as follows (in millions):

Fair value of consideration transferred:
Cash consideration	$	57.8
Working capital adjustment	(0.1		)
Net consideration transferred	$	57.7
Assets acquired, at fair market value:
Cash and cash equivalents	$	2.3
Accounts receivable	5.7
Inventory	9.3
Deferred tax assets	3.5
Prepaid expenses and other current assets	2.2
Total current assets	23.0
Property and equipment	9.9
Intangible assets	27.2
Other assets	1.3
Total assets	$	61.4
Liabilities assumed, at fair market value:
Accounts payable	$	6.1
Accrued liabilities	6.7
Deferred tax liabilities	12.0
Total liabilities assumed	24.8
Identifiable net assets acquired	$	36.6
Goodwill	21.1
Net assets acquired	$	57.7

69

Goodwill is calculated as the excess of the purchase price over the estimated fair values of the assets acquired and the liabilities assumed in the acquisition, and represents the future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. The amount allocated to goodwill associated with the Shemin acquisition is primarily the result of anticipated synergies. None of the goodwill associated with this transaction will be deductible for income tax purposes.

On an unaudited pro forma basis, the following represents the consolidated results of the Company had the Company acquired Shemin as of December 29, 2014 (the first day of the Company’s fiscal year 2015):

Note 6. Employee Benefit and Stock Incentive Plans

The Company sponsors a defined contribution benefit plan for substantially all of its employees. Company contributions to the plan are based on a percentage of employee wages. The Company’s contributions to the plan were approximately $6.4 million, $5.7 million and $4.2 million for the years ended December 31, 2017, January 1, 2017 and January 3, 2016, respectively.

Prior to the adoption of the Omnibus Equity Incentive Plan (the “Omnibus Incentive Plan”), as described below, the Company offered to key employees the ability to purchase common shares of the Company under a stock incentive plan (“Stock Incentive Plan”), which commenced in May 2014 as approved by the stockholders. Common stock options (“options”) were granted with the purchased shares at a predetermined number of options per purchased share. Prior to a public offering these shares were not transferrable except upon the employee’s death, repurchase at the option of the Company, or with the Company’s consent. The Stock Incentive Plan provided for drag-along and tag-along rights if the stockholders sold more than 50.01% of their shares prior to a public offering. As of the date of IPO, 762,079 shares were purchased by employees and outstanding under the Stock Incentive Plan. For the years ended December 31, 2017 and January 1, 2017 respectively, 0 shares and 11,036 shares were repurchased from certain terminated employees by the Company. The Company’s policy was to retain these repurchased shares as treasury shares and not to retire them.

The Company adopted the Omnibus Incentive Plan on April 28, 2016 in connection with the IPO. Upon the adoption of the Omnibus Incentive Plan, the Stock Incentive Plan terminated and no additional awards were made thereunder. However, awards previously granted under the Stock Incentive Plan were unaffected by the termination of the Stock Incentive Plan. Awards under the Omnibus Incentive Plan may be made in the form of stock options, which may be either incentive stock options or non-qualified stock options; stock purchase rights; restricted stock; restricted stock units (“RSUs”); performance shares; performance units; stock appreciation rights (“SARs”); dividend equivalents; deferred stock units (“DSUs”); and other stock-based awards. Any shares covered by an award, or any portion thereof, granted under the Omnibus Incentive Plan or Stock Incentive Plan that terminates, is forfeited, is repurchased, expires or lapses for any reason will again be available for the grant of awards. Additionally, any shares tendered or withheld to satisfy the grant or exercise price or tax withholding obligations pursuant to any award under the Omnibus Incentive Plan will again be available for issuance.

The Company granted 400,415 options, 19,346 DSUs and 49,323 RSUs; in addition, 53,732 options and RSUs were forfeited during the year ended December 31, 2017; and, the Company granted 223,970 options, 26,020 DSUs and 18,973 RSUs; in addition, 17,427 options were forfeited during the year ended January 1, 2017 under the Omnibus Incentive Plan. The RSUs and options granted to employees vest over a four-year period at 25 percent per year. The DSUs granted to non-employee directors vest immediately. Options and RSUs expire ten years after the date of grant. The compensation cost for options and RSUs is recognized on a straight-line basis over the requisite vesting period. The aggregate number of shares which may be issued under the Omnibus Incentive Plan is 2,000,000 shares of which 1,334,749 remain as of December 31, 2017.

The estimated grant-date fair value of stock options was calculated using the Black-Scholes option-pricing model, based on the following weighted-average assumptions:

	December 31, 2017	January 1, 2017	January 3, 2016
Risk-free interest rate	2.11%	1.43%	1.87%
Expected dividends	—	—	—
Expected volatility	30%	30%	36%
Expected term (in years)	6.25	6.25	6.50

Prior to the Company’s IPO, determining the fair value of the shares of common stock underlying stock options was historically based upon a valuation provided by a third-party valuation specialist. The Company’s approach to valuation, which required making complex and subjective judgments, was based on a combination of a discounted cash flow method of income approach and market approaches. The discounted cash flow method used estimates of revenue, driven by assumed market growth rates, and estimated costs as well as appropriate discount rates. These estimates were consistent with the plans and estimates that were used to manage the business. There was inherent uncertainty in making these estimates. Subsequent to the completion of the IPO, the Company uses the market closing price of its common stock as reported on the New York Stock Exchange to determine the fair value of the shares of common stock underlying stock options.

The fair value of each option award was estimated on the date of grant using the Black-Scholes options pricing model. Expected volatilities are based on the historical equity volatility of comparable publicly-traded companies. The expected term of options granted is derived from the output of the option valuation model and represents the period of time that options granted are expected to be outstanding. The

73

risk-free rates utilized for periods throughout the contractual life of the options are based on the U.S. Treasury security yields at the time of grant. The DSUs and RSUs have grant date fair values equal to the fair market value of the underlying stock on the date of grant.

The following table summarizes the information about stock options as of and for the years ended December 31, 2017 and January 1, 2017:

	Number of Shares (in thousands)		Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (Years)	Aggregate Intrinsic Value (in millions)

The total stock option and DSU expense was $5.4 million for the year ended December 31, 2017 and $5.2 million for the year ended January 1, 2017. There were $9.4 million and $8.4 million of unrecognized compensation cost from stock options and DSUs granted under the plan at December 31, 2017 and January 1, 2017, respectively. The unrecognized option and DSU related compensation is expected to be recognized over a weighted-average period of approximately 2.39 years.

The following table summarizes the information about RSUs as of and for the years ended December 31, 2017 and January 1, 2017:

Interest Rate Swaps

The Company utilizes interest rate swap contracts to reduce its exposure to fluctuations in variable interest rates for future interest payments on its syndicated senior Term Loan Facility. In June 2017, the Company entered into two forward-starting interest rate swap contracts to convert the variable interest rate to a fixed interest rate on portions of the borrowings under the Term Loan Facility. The contracts are scheduled to become effective on March 11, 2019 and terminate on June 11, 2021. The following table provides additional details related to the swap contracts (in millions except fixed interest rate):

Derivatives accounted for as hedges	Inception Date	Notional Amount		Fixed Interest Rate		Type of Hedge	Balance Sheet Classification	December 31, 2017		January 1, 2017
Forward-starting interest rate swap 1	June 30, 2017	$	58.0	2.1345	%	Cash flow	Other assets	$	0.2	$	—
Forward-starting interest rate swap 2	June 30, 2017	$	116.0	2.1510	%	Cash flow	Other assets	$	0.4	$	—

The Company recognizes the unrealized gains or unrealized losses as either assets or liabilities at fair value on its Consolidated Balance Sheets. As of December 31, 2017, the fair value changes of the forward-starting interest rate swaps in the amount of $0.6 million was recorded in Other assets.

The Company will recognize any differences between the variable interest rate payments and the fixed interest rate settlements with the swap counterparties as an adjustment to interest expense over the life of the swaps. The Company has designated these swaps as cash flow hedges and records the changes in the estimated fair value of the swaps to Accumulated other comprehensive income (loss) on its Consolidated Balance Sheets. As of December 31, 2017, the fair value changes of the forward-starting interest rate swaps in the amount of $0.6 million was recorded in Accumulated other comprehensive income (loss) as a component of other comprehensive income (loss). To the extent the interest rate swaps are determined to be ineffective, the Company recognizes the changes in the estimated fair value of the swaps in earnings. For the year ended December 31, 2017, there was no ineffectiveness recognized in earnings. The net amount of unrealized gain or loss on derivative instruments included in Accumulated other comprehensive income (loss) related to the forward-starting interest rate swap contracts maturing and expected to be realized during the next twelve months was zero as of December 31, 2017.

Failure of the swap counterparties to make payments would result in the loss of any potential benefit to the Company under the swap agreements. In this case, the Company would still be obligated to pay the variable interest payments underlying the debt agreements. Additionally, failure of the swap counterparties would not eliminate the Company’s obligation to continue to make payments under the existing swap agreements if it continues to be in a net pay position.

Note 8. Income Taxes

In December 2017, the Tax Cuts and Jobs Act (the “2017 Tax Act”) was enacted. The 2017 Tax Act includes a number of changes to existing U.S. tax laws that impact the Company, most notably a reduction of the U.S. corporate income tax rate from 35% to 21%, effective as of January 1, 2018. The 2017 Tax Act also provides for a one-time transition tax on certain foreign earnings that were previously deferred, immediate expensing for certain assets placed into service after September 27, 2017, and a Global intangible low-taxed income (“GILTI”) provision which requires U.S. income inclusion of foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary’s tangible assets.

77

The Company recognized the income tax effects of the 2017 Tax Act in its 2017 financial statements in accordance with Staff Accounting Bulletin No. 118 (“SAB 118”), which provides SEC staff guidance for the application of ASC Topic 740, Income Taxes, in the reporting period in which the 2017 Tax Act was signed into law. At December 31, 2017, the Company has not completed its accounting for the tax effects of enactment of the 2017 Tax Act; however, in certain instances, as described below, the Company has made a reasonable estimate (provisional amount) of the effects on its existing deferred tax balances and one-time transition tax. In other cases, the Company has not been able to make a reasonable estimate and continues to account for those items based on the existing accounting under ASC Topic 740, and the provisions of the tax laws that were in effect prior to enactment. For the items which the Company was able to determine a reasonable estimate, a provisional benefit of $3.2 million was recognized, as described below, which is included as a component of income tax expense from continuing operations. In all cases, the Company will continue to make and refine its calculations as additional analysis is completed. Moreover, the Company’s provisional estimates may also be affected as it gains a more thorough understanding of the 2017 Tax Act. Finally, the Company is evaluating whether it will be subject to incremental U.S. tax on GILTI, beginning in 2018, due to expense allocations required under the U.S. foreign tax credit rules. The Company has provisionally elected to account for GILTI tax in the period in which it is incurred, and therefore, has not provided any provisional deferred tax impacts of GILTI in its consolidated financial statements for the year ended December 31, 2017.

Provisional amounts

Deferred tax assets and liabilities - the Company re-measured certain deferred tax assets and liabilities based on the rates at which these items are expected to reverse in the future, which is 21%. However, the Company is still analyzing certain aspects of the 2017 Tax Act and refining its calculations, which potentially could affect the measurement of these balances or potentially give rise to new deferred tax amounts. The provisional amount recorded related to the re-measurement of the Company’s deferred tax balance was a benefit of $4.5 million.

Foreign tax effects - the one-time transition tax is based on the Company’s total post-1986 earnings and profits (“E&P”) that were previously deferred from U.S. income taxes. The Company recorded a provisional amount for the one-time transition tax liability on E&P from its Canadian subsidiary, resulting in an increase in income tax expense of $1.3 million.  The Company has not yet completed its calculation of the total post-1986 E&P for the Canadian subsidiary. Further, the transition tax is based in part on the amount of those earnings held in cash and other specified assets. This amount may change when the Company finalizes its calculation of post-1986 foreign E&P previously deferred from U.S. federal taxation, and finalizes the amounts held in cash or other specified assets.

Components of net income before taxes were as follows (in millions):

The Company’s effective tax rate was 24.8%, 41.0%, and 40.3% for the years ended December 31, 2017, January 1, 2017, and January 3, 2016, respectively. The following table provides a reconciliation of income tax expense (benefit) at the statutory U.S. federal tax rate to actual income tax expense (benefit) for the periods presented (in millions):

Historically, U.S. income tax has not been recognized on the excess of the amount for financial reporting over the tax basis of the Company’s investment in its Canadian subsidiary caused by foreign earnings that are indefinitely reinvested outside the U.S.  At December 31, 2017, unremitted earnings of the Canadian subsidiary have been included in the computation of the transition tax associated with the 2017 Tax Act.  The Company remains indefinitely reinvested with respect to its initial investment and any associated potential withholding tax on earnings of its Canadian subsidiary subject to the transition tax, as well as with respect to future earnings that will primarily fund the operations of the subsidiary; however, the Company continues to evaluate its position under SAB 118.

Deferred income taxes reflect the expected future tax consequences of temporary differences between the financial statement carrying amount of the Company’s assets and liabilities, tax credits, and loss carry forwards. The significant components of deferred income taxes are as follows (in millions):

79

	December 31, 2017			January 1, 2017
Deferred tax assets:
Net operating losses	$	5.2		$	4.1

Net deferred tax liabilities	$	(8.4	)	$	(20.0	)

The Company evaluates its deferred tax assets to determine the need for a valuation allowance, and to conclude whether it is more likely than not that those deferred income tax assets will be realized. Management assesses the available positive and negative evidence to establish whether sufficient future taxable income will be generated to permit use of the existing deferred tax assets. On the basis of this evaluation, as of December 31, 2017 and January 1, 2017, a valuation allowance of $5.2 million and $4.1 million, respectively, has been recorded against deferred tax assets related primarily to state net operating loss carryforwards for separate returns the Company believes are more likely than not to expire unused. Activity within the tax valuation allowance for the periods was as follows (in millions):

	For the year January 2, 2017 to December 31, 2017		For the year January 4, 2016 to January 1, 2017			For the year December 29, 2014 to January 3, 2016
Beginning balance	$	4.1	$	4.2		$	4.6
Increase in valuation allowance	1.1		—			—
Decrease in valuation allowance	—		(0.1		)	(0.4		)
Ending balance	$	5.2	$	4.1		$	4.2

As of December 31, 2017, the Company had available tax-effected state NOL carryforwards of approximately $5.2 million that will expire at various dates from 2017 through 2028, if not utilized.

The Company recognizes the tax effects of uncertain tax positions only if such positions are more likely than not to be sustained based solely upon its technical merits at the reporting date. The Company refers to the difference between the tax benefit recognized in its financial statements and the tax benefit claimed in the income tax return as an unrecognized tax benefit. There was no expense or liability recorded for unrecognized tax benefits for each period presented. The Company does not expect that the unrecognized tax benefit will materially change over the next 12 months.

The Company’s policy for recording interest and penalties, if any, associated with uncertain tax positions is to recognize interest within the Interest and other non-operating expenses line item, and to recognize penalties in Selling, general and administrative expenses. For each period presented, the Company had no accrued interest or penalties related to uncertain tax positions.

80

The Company is subject to U.S. federal income tax, income tax in multiple state jurisdictions, and Canadian federal and provincial income tax with respect to its foreign subsidiary. With limited exceptions, years prior to 2009 are no longer open to federal, state and local examination by taxing authorities. As part of the Deere consolidated federal return audit, the Company is currently under audit for federal income tax years 2009 through 2013. The Company is also under audit by a number of state and local jurisdictions; however, no audit adjustments are anticipated that would result in a material change to the Company’s financial position.

Deere has indemnified the Company against any taxes, penalties or interest for tax periods prior to the CD&R Acquisition, accruing after the CD&R Acquisition date.

Note 9. Related Party Transactions

Following consummation of the secondary offering on July 26, 2017 (as described in Note 1), CD&R and Deere no longer have an ownership interest in the Company. Transactions with customers and entities that were under the common ownership of CD&R and Deere through July 26, 2017 are considered related-party transactions and are discussed below.

The Company offers a financing plan to its customers through John Deere Financial, f.s.b. (“John Deere Financial”) a wholly-owned subsidiary of Deere. The Company pays John Deere Financial a fee related to the financing offered, which was approximately $0.3 million, $0.5 million and $0.3 million for the period from January 2, 2017 through July 26, 2017 and for the years ended January 1, 2017, and January 3, 2016, respectively.

In connection with the CD&R Acquisition, the Company entered into consulting agreements (the “Consulting Agreements”) with each of CD&R and Deere. CD&R and Deere each provided consulting services under the Consulting Agreements at an annual fee of approximately $1.3 million and $0.7 million plus expense reimbursement for a 10 year term or earlier termination if CD&R’s or Deere’s ownership, respectively, of the Company was reduced below 10%. On May 17, 2016, the Company entered into termination agreements with CD&R and Deere pursuant to which the Company paid CD&R and Deere an aggregate fee of approximately $7.5 million to terminate the Consulting Agreements in connection with the consummation of the IPO. See “Note 11. Redeemable Convertible Preferred Stock” for a discussion of dividends paid to the CD&R investor.

TruGreen is a customer under common ownership of CD&R and therefore became a related party at the time of the CD&R Acquisition. As provided above, TruGreen is no longer a related party as a result of the consummation of the secondary offering on July 26, 2017. Net sales included in the Company’s Consolidated Statement of Operations with TruGreen were $4.3 million for the period from January 2, 2017 through July 26, 2017 and $3.9 million for the year ended January 1, 2017. Accounts receivable included in the Company’s consolidated balance sheets was $0.4 million as of January 1, 2017.

Note 10. Commitments and Contingencies

Litigation: From time to time, the Company is subject to certain claims and lawsuits that have been filed in the ordinary course of business. The Company believes the reasonably possible range of losses for these unresolved legal actions in addition to amounts accrued would not have a material effect on the Company’s assets and liabilities as of December 31, 2017 and January 1, 2017 and revenues, expenses, changes in equity, and cash flows for the years ended December 31, 2017, January 1, 2017, and January 3, 2016.

Environmental liability: As part of the sale of LESCO manufacturing assets in 2005, the Company retained the environmental liability associated with those assets. Remediation activities can vary substantially in duration and cost and it is difficult to develop precise estimates of future site remediation costs. The Company estimated in accrued liabilities the undiscounted cost of future remediation efforts to be approximately $3.8 million and $4.0 million as of December 31, 2017 and January 1, 2017, respectively. As part of the CD&R Acquisition, Deere agreed to pay the first $2.5 million of the liability and cap the Company exposure to approximately $2.4 million. The Company has an indemnification asset against the liability as a result of these actions of $1.4 million and $1.6 million as of December 31, 2017 and January 1, 2017, respectively.

Letter of credit: As of December 31, 2017 and January 1, 2017, outstanding letters of credit were $4.5 million and $2.9 million respectively. There were no amounts drawn on the letters of credit for either period presented.

Purchase commitments: The Company has entered into contracts with various farmers that obligate the Company to purchase certain nursery products and grass seeds. These contracts run through fiscal year 2021. The total future obligation was approximately $58.8 million as of December 31, 2017 with expected payments of approximately $33.1 million, $16.1 million, $8.9 million, $0.7 million and $0.0 million during the years ending December 2018, 2019, 2020, 2021 and 2022, respectively. The Company’s purchases were approximately $33.7 million, $28.1 million and $20.4 million for the years ended December 31, 2017, January 1, 2017 and January 3,

81

2016, respectively. In addition, the Company has entered into various service commitments and definitive agreements to acquire an entity or group of assets; of which, the maximum total future obligation was approximately $9.4 million as of December 31, 2017.

Operating leases: The Company leases buildings and equipment under certain non-cancelable operating leases that expire in various periods through December 2022. Rent expense under operating leases was approximately $48.2 million, $43.5 million and $37.3 million during the years ended December 31, 2017, January 1, 2017 and January 3, 2016, respectively. Certain leases have been subleased to third parties.

Approximate future minimum lease payments under non-cancelable operating leases, net of sublease income, are as follows (in millions):

	Gross lease payments		Sublease Income			Net lease payments
Fiscal year:
2018	$	46.1	$	(0.1	)	$	46.0
2019	38.9		(0.1		)	38.8
2020	30.2		—			30.2
2021	23.5		—			23.5
2022	16.1		—			16.1
Thereafter	72.5		—			72.5
Total minimum lease payments	$	227.3	$	(0.2	)	$	227.1

During the past several years the Company has closed locations under operating leases. The remaining lease payments are accrued and included in accrued liabilities and other long-term liabilities. The aggregate reserve liability was approximately $0.3 million and $0.0 million at December 31, 2017 and January 1, 2017, respectively.

Note 11. Redeemable Convertible Preferred Stock

The CD&R Equity Investment

In connection with the CD&R Acquisition, the Company issued Redeemable Convertible Preferred Stock to the CD&R Investor. On the day prior to the closing of the IPO, all of the then-outstanding Redeemable Convertible Preferred Stock converted into shares of common stock, resulting in the issuance by the Company of an additional 25,303,164 shares of common stock.

Accounting for the Redeemable Convertible Preferred Stock

In accordance with the SEC guidance within ASC Topic 480, Distinguishing Liabilities from Equity: Classification and Measurement of Redeemable Securities, the Company classified the Redeemable Convertible Preferred Stock as mezzanine equity because the Redeemable Convertible Preferred Stock contained a redemption feature which was contingent upon certain change of control events, the occurrence of which was not solely within the control of the Company. These contingent events were not considered probable of occurring and as such the Company did not accrete the mezzanine equity to its redemption value each period. The Company determined that none of the features included in the Redeemable Convertible Preferred Stock were required to be accounted for separately as a derivative under ASC Topic 815, Derivatives and Hedging.

The initial issuance of Redeemable Convertible Preferred Stock did not include a beneficial conversion feature (“BCF”) because the conversion price used to set the conversion ratio at the time of issuance was greater than the initial common stock price. The paid-in-kind dividends in the form of Redeemable Convertible Preferred Stock contained the same conversion price as the original issuance and in certain cases did include a BCF as of the dividend payment date. Since the Redeemable Convertible Preferred Stock did not have a fixed or determinable redemption date and was freely convertible at any time, the Company immediately amortized any BCF recognized through retained earnings. As disclosed in Note 1, on May 2, 2016, the Company paid a one-time special cash dividend to all existing stockholders as of April 29, 2016. CD&R Investor received $112.4 million in accordance with its right to participate in all distributions to common stock on an as-converted basis, in accordance with its right as a preferred stockholder. The Redeemable Convertible Preferred Stock converted to common stock in accordance with its terms on May 16, 2016. During the year ended January 1, 2017, the Company paid the cumulative dividends in cash; and accordingly, no BCF was recognized.

The below table summarizes the changes in the carrying value of the Redeemable Convertible Preferred Stock (in millions):

82

Balance as of January 3, 2016	$	216.8
Shares converted to Common Stock	(216.8		)
Balance as of January 1, 2017	—
Balance as of December 31, 2017	$	—

Note 12. Net Sales by Product

Net Sales from external customers by product category were as follows:

	For the year January 2, 2017 to December 31, 2017		For the year January 4, 2016 to January 1, 2017		For the year December 29, 2014 to January 3, 2016
Agronomic	$	596.3	$	567.9	$	525.1
Irrigation and Outdoor Lighting	621.4		605.9		512.4
Landscape and other	408.0		283.9		233.3
Nursery	236.0		190.5		180.8
	$	1,861.7	$	1,648.2	$	1,451.6

Agronomic Net sales include fertilizer and control product categories.

Note 13. Earnings (Loss) Per Share

Basic earnings (loss) per common share is computed by dividing net income (loss) attributable to common shares by the weighted average number of common shares outstanding for the period. The Redeemable Convertible Preferred Stock had the right to participate in all distributions declared and paid on the Company’s common stock on an as-converted basis, and was therefore considered a participating security. The Company calculates basic earnings per share using the “two-class” method, and for the years ended January 1, 2017 and January 3, 2016 did not allocate the loss available to common stockholders to the Redeemable Convertible Preferred Stock as those holders did not have a contractual obligation to share in net losses. In periods with income available to common stockholders, the Company would reduce income available to common stockholders to reflect the hypothetical distribution of undistributed earnings to the Redeemable Convertible Preferred Stock in accordance with its contractual rights. The Company reduced income available to common stockholders and increased loss attributable to common stockholders to reflect the cumulative dividend on the Company’s Redeemable Convertible Preferred Stock whether or not declared or paid during the period. Similarly, the Company reduced income available to common stockholders and increased loss attributable to common stockholders for any amortization of beneficial conversion features recorded during each period. See Note 11 for a detailed description of the terms of the Redeemable Convertible Preferred Stock.

As disclosed in Note 1, on May 2, 2016, a one-time special cash dividend of $176.0 million was paid to existing stockholders of the Company as of April 29, 2016. Of the $176.0 million special cash dividend, $112.4 million was paid to holders of the Redeemable Convertible Preferred Stock in accordance with its right to participate in all distributions to common stockholders on an as-converted basis. Prior to May 16, 2016, the earnings (loss) per share calculation reflected the impact of the Redeemable Convertible Preferred Stock. Since the special cash dividend was paid prior to conversion of the Redeemable Convertible Preferred Stock, the $112.4 million is reported as a reduction of net income attributable to common shares during the year ended January 1, 2017.

The Company’s computation of diluted earnings (loss) per common share includes the effect of potential common stock, if dilutive. For the years ended December 31, 2017, January 1, 2017 and January 3, 2016, the assumed exercises the Company’s employee stock options, RSUs and DSUs and the conversion of Redeemable Convertible Preferred Stock were anti-dilutive and, therefore, the following potential shares of common stock were not included in the diluted loss per common share calculation:

	December 31, 2017	January 1, 2017	January 3, 2016
Weighted average potential common shares excluded because anti-dilutive
Redeemable Convertible Preferred Stock	—	9,202,870	23,876,230
Employee Stock Options	13,798	3,160,457	2,836,919

83

Certain of the Company’s employee stock options, RSUs and DSUs were dilutive and resulted in additional potential common shares included in the Company’s calculation of diluted earnings per common share of 2,438,835, 0 and 0 for the years ended December 31, 2017, January 1, 2017 and January 3, 2016, respectively.

Note 14. Subsequent Events

On January 3, 2018, the Company acquired the assets and assumed the liabilities of Pete Rose, Inc. (“Pete Rose”) with one location in Richmond, Virginia. Pete Rose is a market leader in the distribution of natural stone and hardscape material to landscape professionals.

On February 12, 2018, the Company acquired the outstanding stock of Atlantic Irrigation Specialties, Inc. and the limited liability company interests of Atlantic Irrigation South, LLC (collectively, “Atlantic”) with 33 locations in 12 states within the Eastern U.S. and two provinces in Eastern Canada.  Atlantic is a leader in the distribution of irrigation, lighting, drainage, and landscaping equipment to green industry professionals.

The acquisitions are not material and not expected to have a significant impact on the consolidated financial statements.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

None.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as such term is defined in Rule 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 as amended) as of December 31, 2017. Based upon that evaluation, our Chief Executive Officer and our Chief Financial Officer concluded that as of December 31, 2017, our disclosure controls and procedures were designed at a reasonable assurance level and were effective to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission (SEC), and that such information is accumulated and communicated to our management, including our CEO and CFO, as appropriate, to allow timely decisions regarding required disclosure.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rule 13a-15(f) or 15d-15(f) promulgated under the Securities Exchange Act of 1934 as a process designed by, or under the supervision of, the company’s principal executive and principal financial officers, and effected by the Company’s board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:

• Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the company;

• Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and

• Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s assets that could have a material effect on the financial statements.

Our internal control system was designed to provide reasonable assurance to our management and Board of Directors regarding the preparation and fair presentation of published financial statements. All internal control systems, no matter how well designed, have inherent limitations which may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our management assessed the effectiveness of our internal controls over financial reporting as of December 31, 2017. In making this assessment, we used the criteria set forth in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (COSO). Based on our assessment, we believe that, as of December 31, 2017, our internal control over financial reporting was effective at a reasonable assurance level based on those criteria.

Under guidelines established by the SEC, companies are allowed to exclude an acquired business from management's report on internal control over financial reporting for the first year subsequent to the acquisition while integrating the acquired operations. Accordingly, management has excluded Evergreen, Marshall Stone and Harmony Gardens from its annual report on internal control over financial reporting as of December 31, 2017. Evergreen, Marshall Stone and Harmony Gardens collectively represented less than 2% and 1% of the Company's consolidated total assets and consolidated net sales, respectively, as of and for the year ended December 31, 2017.

Our Independent Registered Public Accounting Firm has issued a report on the Company’s internal control over financial reporting. This report appears below.

Report of Independent Registered Public Accounting Firm

To the stockholders and the Board of Directors of SiteOne Landscape Supply, Inc.

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of SiteOne Landscape Supply, Inc.  and subsidiaries (the “Company”) as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB),  the consolidated financial statements as of and for the year ended December 31, 2017, of the Company and our report dated February 28, 2018, expressed  an unqualified opinion on those financial statements.

As described in Management’s Report on Internal Control over Financial Reporting, management has excluded Evergreen, Marshall Stone and Harmony Gardens from its annual report on internal control over financial reporting as of December 31, 2017. Evergreen, Marshall Stone and Harmony Gardens collectively represented less than 2% and 1% of the Company's consolidated total assets and consolidated net sales, respectively, as of and for the year ended December 31, 2017. Accordingly, our audit did not include the internal control over financial reporting at Evergreen, Marshall Stone, and Harmony Gardens.

Basis for Opinion

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

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

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

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

Notes to Condensed Parent Company Only Financial Statements

Note 1. Description of SiteOne Landscape Supply, Inc.

SiteOne Landscape Supply, Inc. (“Holdings” or the “Parent”) indirectly owns 100% of the membership interest in SiteOne Landscape Supply Holding, LLC (“Landscape Holding” or “subsidiary”), which it acquired from Deere & Company on December 23, 2013 (the “Closing Date”) in exchange for its common stock initially representing 40% of the outstanding capital stock (on an as-converted basis). In addition, Holdings issued cumulative convertible participating redeemable preferred stock (“Redeemable Convertible Preferred Stock”) to Clayton, Dubilier & Rice, LLC (“CD&R”) initially representing 60% of its remaining outstanding capital stock (on an as-converted basis) (both events collectively referred to herein as the “CD&R Acquisition”). On May 2, 2016, Holdings paid a one-time special cash dividend to all existing stockholders as of April 29, 2016. CD&R received $112.4 million in accordance with its right to participate in all distributions to common stock on an as-converted basis, in accordance with its right as a preferred stockholder. On the day prior to the closing of the initial public offering, all of the then-outstanding Redeemable Convertible Preferred Stock converted into shares of common stock, resulting in the issuance by Holdings of an additional 25,303,164 shares of common stock. On December 5, 2016, May 1, 2017 and July 26, 2017, Holdings completed secondary offerings of its common stock in which Deere and CD&R were the sole sellers. Following consummation of the secondary offering on July 26, 2017 , CD&R and Deere no longer have an ownership interest in Holdings. Holdings has no significant operations or assets other than its indirect ownership of the equity of Landscape Holding. Accordingly, the Holdings is dependent upon distributions from Landscape Holding to fund its obligations. However, under the terms of Landscape Holding’s credit agreements governing Landscape Holding’s ABL Facility and Term Loan Facility, Landscape Holding’s ability to pay dividends or lend to Holdings is restricted. Landscape Holding has no obligation to pay dividends to Holdings except to pay specified amounts to Holdings in order to fund the payment of Holdings’ tax obligations.

Note 2. Basis of Presentation

The accompanying Condensed Parent Only Financial Statements include the amounts of Holdings and its investment in subsidiary since the Closing Date under the equity method, and do not present the financial statements of Holdings and its subsidiary on a consolidated basis. Under the equity method, investment in subsidiary is stated at cost plus contributions and equity in undistributed income (loss) of subsidiary less distributions received since the date of acquisition. These condensed Parent Company Only Financial Statements should be read in conjunction with SiteOne Landscape Supply, Inc. Consolidated Financial Statements and their accompanying Notes to Consolidated Financial Statements.

Note 3. Income Taxes

With respect to the CD&R Acquisition, $9.8 million of transaction expenses were recorded within the period ended December 29, 2013. Of the $9.8 million of transaction expenses, $3.7 million were not deductible for tax purposes, and the remaining $6.1 million ($2.2 million tax-effected) were capitalized for tax purposes as a deferred tax asset. During the years end December 31, 2017 and January 1, 2017, respectively, $0.4 million ($0.2 million tax-effected) and $0.4 million ($0.1 million tax-effected) has been amortized, which gives rise to a net operating loss and current tax benefit that offsets the deferred tax expense by the same amount.

In December 2017, the Tax Cuts and Jobs Act (the “2017 Tax Act”) was enacted. The 2017 Tax Act includes a number of changes to existing U.S. tax laws that impact the Company, most notably a reduction of the U.S. corporate income tax rate from 35% to 21%, effective as of January 1, 2018. As a result, the Company re-measured its deferred tax asset based on the rates at which this item is expected to reverse in the future, which is 21%. The Company recognized the income tax effects of the 2017 Tax Act in its 2017 financial statements in accordance with Staff Accounting Bulletin No. 118, which provides SEC staff guidance for the application of ASC Topic 740, Income Taxes, in the reporting period in which the 2017 Tax Act was signed into law. At December 31, 2017, the Company has not completed its accounting for the tax effects of enactment of the 2017 Tax Act; however, the Company has made a reasonable estimate (provisional amount) of the effect on its existing deferred tax asset. The Company is still analyzing certain aspects of the 2017 Tax Act and refining its calculations, which potentially could affect the measurement of this balance or potentially give rise to new deferred tax amounts. The provisional amount recorded related to the re-measurement of our deferred tax asset was an expense of $0.6 million. As of December 31, 2017, the deferred tax asset related to these transaction expenses has a balance of $1.0 million.

Based on the nature of SiteOne Landscape Supply, Inc.’s products and customers’ business cycles, sales are significantly higher in the spring and summer months.

Common Stock Split

On April 29, 2016, the Company filed a Certificate of Amendment to amend and restate the Company’s Certificate of Incorporation in the State of Delaware, effecting an 11.6181 for 1 common stock split. Each stockholder’s percentage ownership and proportional voting power remained unchanged as a result of the stock split. All applicable share data, per share amounts and related information in the consolidated financial statements and notes thereto have been adjusted retroactively to give effect to the 11.6181 for 1 common stock split.

Refinancing and Amendments of Term Loan and Special Cash Dividend

On April 29, 2016, the Company refinanced the existing term loan facility (the “Prior Term Loan Facility”) with an amended and restated $275.0 million term loan facility maturing in April 2022 (the “Term Loan Facility”). On April 29, 2016, the proceeds from the Term Loan Facility were used to repay all $60.3 million of borrowings outstanding under the Prior Term Loan Facility, to repay $29.9 million of borrowings outstanding under the senior asset-based credit facility (the “ABL Facility”), and to pay fees and expenses associated with the refinancing transaction.

On May 2, 2016, a one-time special cash dividend of $176.0 million was paid to existing holders of the Company’s common stock and cumulative convertible participating redeemable preferred stock (“Redeemable Convertible Preferred Stock”) as of April 29, 2016 out of the proceeds from the Refinancing of the Term Loan Facility. Of the $176.0 million paid to stockholders, $112.4 million was paid to holders of the Redeemable Convertible Preferred Stock in accordance with their right to participate in all distributions to common stockholders on an as-converted basis. The Redeemable Convertible Preferred Stock converted to common stock in accordance with its terms on May 16, 2016 resulting in the issuance by the Company of an additional 25,303,164 shares of its common stock which common shares are included in the weighted average common shares outstanding from that date forward. Prior to May 16, 2016, the Company’s earnings (loss) per share calculation reflected the impact of the Redeemable Convertible Preferred Stock. Since the special cash dividend was paid prior to conversion of the Redeemable Convertible Preferred Stock, the $112.4 million is reported as a reduction of net income attributable to common shares for the year ended January 1, 2017. In conjunction with the payment of the special cash dividend, the Company reduced the exercise price of certain outstanding options and made a cash payment of $2.8 million to certain holders of options to offset the dilutive impact of the special cash dividend.

On November 23, 2016, the Company amended the Term Loan Facility to, among other things, (i) add an additional credit facility under the Term Loan Facility consisting of additional term loans (the “Tranche B Term Loans”) in an aggregate principal amount of $273.6 million and (ii) increase the aggregate principal amount of Tranche B Term Loans under the Term Loan Facility to $298.6 million pursuant to an increase supplement. Proceeds of the Tranche B Term Loans were used to, among other things, (i) repay in full the term loans outstanding under the Term Loan Facility immediately prior to effectiveness of the Term Loan Facility Amendments (the “Existing Term Loans”) and (ii) repay $21.0 million of borrowings outstanding under the ABL Facility.

On May 24, 2017, the Company amended the Term Loan Facility (the “Second Amendment”) to, among other things, add an additional credit facility under the Term Loan Facility consisting of additional term loans (the “Tranche C Term Loans”) in an aggregate principal amount of $299.5 million. Proceeds of the Tranche C Term Loans were used to, among other things, repay in full the Tranche B Term Loans outstanding under the Term Loan Facility immediately prior to effectiveness of the Second Amendment and pay fees and expenses associated with the transaction.

On December 12, 2017, the Company amended the Term Loan Facility (the “Third Amendment”) to, among other things, (i) add an additional credit facility under the Term Loan Facility consisting of additional term loans (the “Tranche D Term Loans”) in an aggregate principal amount of $298.0 million and (ii) increase the aggregate principal amount of Tranche D Term Loans under the Term Loan Facility to $350.0 million. Proceeds of the Tranche D Term Loans were used to, among other things, (i) repay in full the Tranche C Term Loans and (ii) repay approximately $50.7 million of borrowings outstanding under the ABL Facility.

Basis of financial statement presentation:

SiteOne Landscape Supply, Inc. (hereinafter, collectively with all its consolidated subsidiaries, referred to as the “Company” or individually as “Holdings”) indirectly owns 100% of the membership interest in SiteOne Landscape Supply Holding, LLC (referred to herein as “Landscape Holding”). Landscape Holding is parent and sole owner of SiteOne Landscape Supply, LLC (referred to herein as “Landscape”). Prior to the transaction described below, Deere & Company (“Deere”) was the sole owner of SiteOne Landscape Supply Holding, LLC.

On December 23, 2013 (the “Closing Date”), the Company acquired 100% of the ownership interest in Landscape Holding from Deere in exchange for common shares of the Company initially representing 40% of the outstanding capital stock (on an as-converted basis) plus cash consideration of approximately $314 million, net of pre-closing and post-closing adjustments. In order to facilitate the transaction, the Company issued cumulative convertible participating redeemable preferred stock (“Redeemable Convertible Preferred Stock”) to Clayton, Dubilier & Rice, LLC (“CD&R”) for total consideration of $174 million initially representing 60% of the outstanding capital stock (on an as-converted basis). As part of the same transaction, Landscape Holding also acquired from Deere the affiliated company LESCO, Inc. (“LESCO”). The Company continues to be the sole owner of Landscape Holding. The aforementioned transactions described in this paragraph are referred to herein as the “CD&R Acquisition”.

Following consummation of the secondary offering on July 26, 2017, CD&R and Deere no longer have an ownership interest in the Company.

The Company’s chief operating decision maker (“CODM”) manages the business as a single reportable segment. Within the organizational framework, the same operational resources support multiple geographical regions and performance is evaluated primarily by the CODM at a consolidated level. The CODM also evaluates regional performance based on financial and operational measures and receives discrete financial information on a regional basis. Since all of the Company’s regions have similar operations and share similar economic characteristics, the Company aggregates regions into a single operating and reportable segment. These similarities include 1) long-term financial performance, 2) the nature of products and services, 3) the types of customers the Company sells to and 4) the distribution methods used. Further, all of the Company’s product categories have similar supply chain processes, classes of customers and economic characteristics.

The accompanying audited financial statements of the Company included herein have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”).

The Consolidated Statements of Operations, Comprehensive income (loss), Equity and Cash Flows for the Company are presented for the fiscal years ended December 31, 2017, January 1, 2017 and January 3, 2016. The consolidated financial statements for the Company include the assets and liabilities used in operating the Company’s business, including entities in which the Company owns or controls more than 50% of the voting shares. The Company owns 100% of all subsidiaries presented in these financial statements. All intercompany balances and transactions have been eliminated in consolidation.

Significant accounting policies:

Use of estimates in the preparation of financial statements: The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Fiscal year: The Company’s fiscal year is a 52- or 53-week period ending on the Sunday nearest to December 31. The year ended December 31, 2017 includes 52 weeks. The year ended January 1, 2017 includes 52 weeks. The year ended January 3, 2016 includes 53 weeks.

Cash and cash equivalents: Cash and cash equivalents include primarily cash on deposit with banks which, at times, may exceed federally insured limits. The Company has not experienced any losses in these accounts. Cash and cash equivalents also include unsettled credit card transactions.

Accounts receivable: The Company carries accounts receivable at the original invoice amount less any charge-offs and the allowance for credit losses and doubtful accounts. Allowances for credit losses and doubtful accounts are maintained in amounts considered to be appropriate in relation to the receivables outstanding based on collection experience, economic conditions and credit risk quality. Receivables are written-off to the allowance when an account is considered uncollectible.

Activity in the allowance for doubtful accounts for the periods was as follows (in millions):

	For the year January 2, 2017 to December 31, 2017			For the year January 4, 2016 to January 1, 2017			For the year December 29, 2014 to January 3, 2016
Beginning balance	$	4.3		$	3.6		$	3.0
Provision (reduction) for allowance	2.0			1.1			1.0
Write-offs, net of recoveries	(1.6		)	(0.4		)	(0.4		)
Ending balance	$	4.7		$	4.3		$	3.6

Inventory: The majority of the Company’s inventories are valued at the lower of cost or net realizable value, with cost determined by the first-in, first-out (“FIFO”) method. Inventory is primarily considered to be finished goods. The Company establishes a reserve for excess, slow-moving, and obsolete inventory that is equal to the difference between the cost and estimated net realizable value for that inventory. These reserves are based on a review of planned and historical sales. The reserve for obsolete and excess inventory was approximately $5.1 million and $4.8 million as of December 31, 2017 and January 1, 2017, respectively.

Property and equipment, net: Property and equipment is stated at cost less accumulated depreciation. Depreciation is computed on property and equipment using the straight-line method over the estimated useful lives of the assets, as noted below. Leasehold improvements are depreciated over the lesser of their estimated useful lives or the remaining lease terms. Depreciation on property and equipment under capital lease is included in depreciation expense. Expenditures for replacement or major renewals of significant items are capitalized. Expenditures for maintenance, repairs and minor renewals are generally charged to expense as incurred.

Asset Class	Estimated Useful Life
Buildings and improvements	20 years
Branch equipment	2 to 12 years
Furniture and fixtures	2 to 12 years
Auto and truck	2 to 6 years
Tooling	7 years
Leasehold improvements	Shorter of the estimated useful life or the term of the lease, considering renewal options expected to be exercised.

Acquisitions: When the Company acquires a controlling financial interest in an entity or group of assets that are determined to meet the definition of a business, the acquisition method described in ASC Topic 805, Business Combinations, is applied. The Company allocates the purchase consideration paid to acquire the business to the assets and liabilities acquired based on estimated fair values at the acquisition date, with the excess of purchase price over the estimated fair value of the net assets acquired recorded as goodwill. If during the measurement period (a period not to exceed 12 months from the acquisition date) the Company receives additional information that existed as of the acquisition date but at the time of the original allocation described above was unknown, the Company makes the appropriate adjustment to the purchase price allocation in the reporting period in which the adjustment is identified.

Goodwill impairment: Goodwill represents the acquired fair value of a business in excess of the fair values of tangible and identified intangible assets acquired and liabilities assumed. The Company tests goodwill on an annual basis as of July fiscal month end and additionally if an event occurs or circumstances change that would indicate the carrying amount may be impaired. Examples of such indicators include a significant change in the business climate, unexpected competition, loss of key personnel or a decline in the Company’s market capitalization below the Company’s net book value. The Company performs impairment assessments at the reporting unit level, which is defined as an operating segment or one level below an operating segment, also known as a component.

With the issuance of Accounting Standards Update 2017-04 Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (“ASU 2017-04”) in January 2017, and adopted by the Company in July 2017 with its annual goodwill impairment test, the impairment test is now a single-step process. The process requires the Company to estimate and compare the fair value of a reporting unit to its carrying amount, including goodwill. If the fair value exceeds the carrying amount, the goodwill is not considered impaired. To the extent a reporting unit’s carrying amount exceeds its fair value, the reporting unit’s goodwill is deemed impaired, and an impairment charge is recognized based on the excess of a reporting unit’s carrying amount over its fair value.No impairment occurred during the periods presented. See Note 4 for a more detailed description of goodwill.

Intangible assets, net: Intangible assets include customer relationships, and trademarks and other, acquired through acquisitions. Intangibles assets with finite useful lives are amortized on an accelerated method or a straight-line of amortization over their estimated useful lives. An accelerated amortization method reflecting the pattern in which the asset will be consumed is utilized if that pattern can be reliably determined. If that pattern cannot be reliably determined, a straight-line amortization method is used. The Company considers the period of expected cash flows and underlying data used to measure the fair value of the intangible assets when selecting a useful life. Refer to Note 4 for a more detailed description of intangible asset amortization.

Impairment of Long-lived assets: Long-lived assets, primarily property and equipment, finite-lived intangible assets and long-term contracts included in other assets, are evaluated for impairment whenever events or changes in circumstances indicate the carrying value of an asset group may not be recoverable. The recoverability of an asset group is measured by a comparison of the carrying amount of the asset group to its future undiscounted cash flows.

If the recoverability test indicates the asset group balances are not recoverable, the Company would recognize an impairment charge to reduce the long-lived asset balances based on the fair value of the asset group. The amount of such impairment would be charged to operations in the current period. There were no impairment charges recognized during the years ended December 31, 2017, January 1, 2017 and January 3, 2016.

Fair value measurement: Fair value is defined as an exit price, representing an amount that would be received to sell an asset or the amount paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The inputs used to measure fair value are prioritized into the following three-tiered value hierarchy:

• Level 1: Unadjusted quoted prices in active markets for identical assets or liabilities.

• Level 2: Unadjusted quoted prices in active markets for similar assets or liabilities, unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active or inputs, other than quoted prices in active markets, which are observable either directly or indirectly.

• Level 3: Unobservable inputs for which there is little or no market data.

The hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. The classification of fair value measurement within the hierarchy is based upon the lowest level of input that is significant to the measurement.

The Company’s financial instruments consist of cash and cash equivalents, accounts receivables, forward-starting interest rate swap contracts and long-term debt. The variable interest rate on the long-term debt is reflective of current market borrowing rates. As such, the Company has determined that the carrying value of these financial instruments approximates fair value.

Interest Rate Swaps:

The Company utilizes interest rate swap contracts to reduce its exposure to fluctuations in variable interest rates for future interest payments on its syndicated senior Term Loan Facility. For determining the fair value of the interest rate swap contracts, the Company uses significant observable market data or assumptions (Level 2 inputs) that market participants would use in pricing similar assets or liabilities, including assumptions about counterparty risk. The fair value estimates reflect an income approach based on the terms of the interest rate swap contracts and inputs corroborated by observable market data including interest rate curves. The Company has designated these swaps as cash flow hedges, for which the Company records the effective portions of changes in their fair value, net of tax, in other comprehensive income (loss). To the extent the interest rate swaps are determined to be ineffective, the Company recognizes the changes in the estimated fair value of the swaps in earnings.

Revenue recognition: The Company recognize revenue when the following four basic criteria are met: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services have been rendered; (3) the price to the buyer is fixed or determinable; and (4) collectability is reasonably assured.

Sales of products are recorded when the sales price is determinable and the risks and rewards of ownership are transferred to independent parties. This transfer occurs primarily when goods are picked up by a customer at the branch or when goods are delivered to a customer location. In all cases, when a sale is recorded by the Company, no significant uncertainty exists surrounding the purchaser’s obligation to pay. Returns are estimated and accrued at the time a sale is recognized. The Company makes appropriate provisions based on experience for costs such as doubtful receivables and sales incentives. The Company also has entered into agency agreements with certain of its suppliers whereby the Company operates as a sales agent of those suppliers. The suppliers retain title to their merchandise until it is sold by the Company and determine the prices at which the Company can sell the suppliers’ merchandise. As such, the Company recognizes these agency sales on a net basis and records only the product margin as commission revenue within Net sales.

Sales incentives: The Company offers certain customers rebates which are accrued based on sales volumes. In addition, the Company offers a points-based reward program whereby reward points can be redeemed for merchandise or credit on account (such as gift cards or vacation trips). The Company accrues a liability for this program based on sales volumes and an estimate of points that will be redeemed before expiration. Liabilities for these sales incentives are included in Accrued Liabilities.

Sales taxes: The Company collects and remits taxes assessed by different governmental authorities that are both imposed on and concurrent with revenue producing transactions between the Company and its customers. These taxes may include sales, use, value-added and some excise taxes. The Company reports the collection of these taxes on a net basis (excluded from sales).

Cost of goods sold: Cost of goods sold includes all inventory costs, such as purchase price from suppliers, net of any rebates received, as well as inbound freight and handling, and other costs associated with the inventory and is exclusive of the cost to deliver the products to customers.

Shipping and handling costs: Shipping and handling costs associated with inbound freight are included in Cost of goods sold.

Warranty Reserves: Provisions for estimated warranty costs for the return of nursery product are provided for in the same period the related sales are recorded. The Company offers product warranties on selected nursery items. The warranty reserve is based on historical and current trends. The warranty reserve included in Accrued liabilities was approximately $0.5 million and $0.4 million as of December 31, 2017 and January 1, 2017, respectively.

Leases:The Company leases the majority of its facilities and enters into various other operating lease agreements in conducting its business. At the inception of each lease, the Company evaluates the lease agreement to determine whether the lease is an operating or capital lease. Operating lease expenses are recognized in the statements of operations on a straight-line basis over the term of the related lease. Some of the Company’s lease agreements may contain renewal options, tenant improvement allowances, rent holidays or rent escalation clauses. When such items are included in a lease agreement, the Company records a deferred rent asset or liability on the consolidated balance sheets equal to the difference between the rent expense and cash rent payments.

The cost of property and equipment acquired under capital lease arrangements represents the lesser of the present value of the minimum lease payments or the fair value of the leased asset as of the inception of the lease.

Advertising costs: Advertising costs are charged to expense as incurred and were approximately $2.1 million, $0.9 million, and $0.4 million, during the years ended December 31, 2017, January 1, 2017 and January 3, 2016, respectively.

Stock-based compensation: The Company applies the fair value method to recognize compensation expense for stock-based awards. Using this method, the estimated grant-date fair value of the award is recognized on a straight-line basis over the requisite service period based on the portion of the award that is expected to vest.

Stock-based compensation expense for restricted stock units is measured based on the fair value of the Company’s common stock on the grant date. The Company utilizes the Black-Scholes option pricing model to estimate the grant-date fair value of option awards. The exercise price of option awards is set to equal the estimated fair value of the common stock at the date of the grant. The following weighted-average assumptions are also used to calculate the estimated fair value of option awards:

• Expected volatility: The expected volatility of the Company’s shares is estimated using the historical stock price volatility over the most recent period commensurate with the estimated expected term of the awards.

• Expected term: For employee stock option awards, the Company determines the weighted average expected term equal to the weighted period between the vesting period and the contract life of all outstanding options.

• Dividend yield: The Company has not paid dividends and does not anticipate paying a cash dividend in the foreseeable future and, accordingly, uses an expected dividend yield of zero.

• Risk-free interest rate: The Company bases the risk-free interest rate on the implied yield available on a U.S. Treasury note with a term equal to the estimated expected term of the awards.

Refer to Note 6 for further details regarding stock-based compensation.

Other income: Other income consists primarily of financing charges and net gain/loss on sale of assets.

Income taxes: The Company files a consolidated federal income tax return and files both combined or unitary state income tax returns as well as separate state income tax returns in certain jurisdictions.

Deferred taxes are provided on an asset and liability method in which deferred tax assets are recognized for deductible temporary differences and operating loss and tax credit carry forwards, and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax basis. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment. Realization of deferred tax assets is dependent upon sufficient future taxable income.

The Company’s operations involve dealing with uncertainties and judgments in the application of complex tax regulations in a multitude of jurisdictions. The Company reports a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return based on its estimate of whether, and the extent to which, additional taxes will be due. The Company recognizes interest, if any, related to unrecognized tax benefits within the Interest and other non-operating expenses line item, and recognizes penalties in Selling, general and administrative expenses.

In December 2017, the Tax Cuts and Jobs Act (the “2017 Tax Act”) was enacted. The 2017 Tax Act includes a number of changes to existing U.S. tax laws that impact the Company, most notably a reduction of the U.S. corporate income tax rate from 35% to 21%, which required the Company to re-measure certain deferred tax assets and liabilities in the reporting period in which the 2017 Tax Act was signed into law, a one-time transition tax on certain foreign earnings that were previously deferred, and immediate expensing for certain assets placed into service after September 27, 2017. The Company recognized the income tax effects of the 2017 Tax Act in its 2017 financial statements in accordance with Staff Accounting Bulletin No. 118, which provides SEC staff guidance for the application of ASC Topic 740, Income Taxes. At December 31, 2017, the Company has not completed its accounting for the tax effects of enactment of the 2017 Tax Act. In certain instances, however, the Company has made a reasonable estimate (provisional amount) of the effects with respect to existing deferred tax balances and the one-time transition tax. In other cases, the Company has not been able to make a reasonable estimate and continues to account for those items based on existing accounting under ASC Topic 740, and the provisions of the tax laws that were in effect prior to enactment. In all cases, the Company will continue to make and refine its calculations as additional analysis is completed, and provisional estimates may also be affected as the Company gains a more thorough understanding of the 2017 Tax Act. See Note 8 for further information pertaining to income taxes.

Foreign currency translation: The functional currency for the Company’s Canadian operations is the Canadian dollar, the local currency. The assets and liabilities of these operations are translated into U.S. dollars at the end of the period exchange rates. The revenues and expenses are translated at average exchange rates for the period. The gains or losses from these translations are recorded in other comprehensive income (loss). Gains or losses recognized on transactions denominated in a currency other than the functional currency are included in net income (loss).

Beneficial conversion features: The Company had issued Redeemable Convertible Preferred Stock with dividends that were paid-in-kind during the years ended January 3, 2016 and December 28, 2014. The Company recorded paid-in-kind dividends at carrying value on the issuance date. The paid-in-kind dividends in the form of Redeemable Convertible Preferred Stock contained the same conversion rate as the Redeemable Convertible Preferred Stock issued on the Closing Date. For certain Redeemable Convertible Preferred Stock issued as dividends paid-in-kind, the stated conversion price was determined to be less than the common stock price as of the dividend payment date resulting in the recognition of a beneficial conversion feature (“BCF”) in additional paid-in capital. Since the Redeemable Convertible Preferred Stock did not have a fixed or determinable redemption date and was readily convertible at any time, the Company immediately amortized any BCF recognized through retained earnings. The Redeemable Convertible Preferred Stock converted to common stock in accordance to its terms on May 16, 2016.

Recently Issued and Adopted Accounting Pronouncements

In September 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-16, Business Combinations, an update to the existing guidance under the Business Combinations topic. This update simplifies the accounting for measurement-period adjustments. The amendments in this update require that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. This update will be effective for all annual and interim periods beginning after December 15, 2015. The amendments in this update should be applied prospectively to adjustments to provisional amounts that occur after the effective date of this update with earlier application permitted for financial statements that have not been issued. The adoption of this update did not have a material impact on the Company’s consolidated financial statements.

In July 2015, the FASB issued ASU 2015-11, “Inventory (Topic 330): Simplifying the Measurement of Inventory” (“ASU 2015-11”), which requires entities to measure inventory at the lower of cost or net realizable value rather than at the lower of cost or market. Net realizable value is defined as the estimated selling price in the ordinary course of business less reasonably predictable costs of completion, disposal and transportation. The Company adopted ASU 2015-11 when it became effective in the first quarter of the 2017 Fiscal Year. The adoption of ASU 2015-11 did not have a material impact on the Company’s consolidated financial statements.

In March 2016, the FASB issued ASU 2016-09, “Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting” (“ASU 2016-09”), which simplifies several aspects of the accounting for employee share-based payment transactions for both public and nonpublic entities, including the accounting for income taxes, forfeitures and statutory tax withholding requirements, as well as classification in the statement of cash flows. The Company adopted ASU 2016-09 when it became effective in the first quarter of the 2017 Fiscal Year on a prospective basis and as such, the Company’s prior year presentation has not changed. The primary impact of the adoption was the recognition of excess tax benefits as a reduction of Income tax expense on the Company’s Consolidated Statements of Operations. As a result, excess tax benefits of $6.8 million were recognized as a reduction of Income tax expense for the year ended December 31, 2017. Historically, these amounts were recorded as Additional paid-in capital in Stockholders’ equity on the Company’s Consolidated Balance Sheets. The Company also elected to adopt the cash flow presentation of the excess tax benefits prospectively commencing in the first quarter of 2017. The Company now presents excess tax benefits or tax deficiencies within operating cash flows versus financing activities on the Consolidated Statements of Cash Flows. Another impact of the adoption is that the calculation of the effect of dilutive securities now excludes any derived excess tax benefits or deficiencies from assumed future proceeds, resulting in an increase in diluted weighted average shares outstanding. Additionally, the Company elected to account for forfeitures of share-based payments as they occur and there was no material financial impact as a result. None of the other provisions in ASU 2016-09 had a material impact on the Company’s consolidated financial statements.

In January 2017, the FASB issued ASU 2017-04, “Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment” (“ASU 2017-04”), which eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge (also known as Step 2 under the current guidance). Rather, the measurement of a goodwill impairment charge will be based on the excess of a reporting unit’s carrying value over its fair value (Step 1 under the current guidance). ASU 2017-04 will be effective for annual and interim goodwill impairment tests performed in periods beginning after December 15, 2019 and should be applied prospectively. Early adoption is permitted for annual and interim goodwill impairment tests beginning after January 1, 2017. The Company adopted ASU 2017-04 in July 2017 with its annual goodwill impairment test. The adoption of ASU 2017-04 did not have a material impact on the Company’s consolidated financial statements and related disclosures.

In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities” (“ASU 2017-12”), which seeks to improve the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements. Additionally, ASU 2017-12 makes certain targeted improvements to simplify the application of the hedge accounting guidance in current GAAP based on the feedback received from preparers, auditors, users, and other stakeholders. ASU 2017-12 adds new disclosure requirements, amends existing ones and removes the requirement for entities to disclose amounts of hedge ineffectiveness. In addition, an entity must now provide tabular disclosures about: both (i) the total amounts reported in the statement of financial performance for each income and expense line item that is affected by fair value or cash flow hedging and (ii) the effects of hedging on those line items; and the carrying amounts and cumulative basis adjustments of items designated and qualifying as hedged items in fair value hedges. Early adoption is permitted in any interim period after issuance of ASU 2017-12. The Company adopted ASU 2017-12 in the third quarter of the 2017 Fiscal Year. The adoption of ASU 2017-12 did not have a material impact on the Company’s consolidated financial statements.

Accounting Pronouncements Issued But Not Yet Adopted

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”), which amends existing revenue recognition standards and establishes a new Accounting Standards Codification (“ASC”) Topic 606. The core principle of this amendment is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for these goods or services. The Company has concluded that it will have substantially similar performance obligations under the amended guidance as compared with deliverables and units of account currently being recognized. Additionally, the Company has made policy elections within the amended standard that are consistent with its current accounting. The Company has evaluated the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures and controls. Based on its assessment, the Company has determined that the adoption of ASU 2014-09 will result in additional revenue recognition disclosures, and will have an immaterial impact on the timing of revenue recognition related to its incentive programs. The Company also evaluated other considerations within the guidance and concluded that there are no additional changes required with adopting ASU 2014-09. The Company will adopt ASU 2014-09 in the first quarter of 2018 using the modified retrospective transition method.

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” (“ASU 2016-02”), which amends the guidance for recognition, measurement, presentation and disclosures of lease arrangements and establishes a new ASC Topic 842. The amended standard will require recognition on the balance sheet for all leases with terms longer than 12 months as a lease liability and as a right-of-use asset. The lease liability is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis, and the right-of-use asset is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. The new standard requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. ASU 2016-02 is effective for the Company commencing in the first quarter of fiscal year 2019. The Company is currently evaluating the amended guidance and the impact on its consolidated financial statements and related disclosures.

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326) - Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”), which changes the way companies evaluate credit losses for most financial assets and certain other instruments. For trade and other receivables, held-to-maturity debt securities, loans and other instruments, entities will be required to use a new forward-looking “expected loss” model to evaluate impairment, potentially resulting in earlier recognition of allowances for losses. The new standard also requires enhanced disclosures, including the requirement to disclose the information used to track credit quality by year of origination for most financing receivables. ASU 2016-13 will be effective for the Company commencing in the first quarter of fiscal year 2020. The guidance must be applied using a cumulative-effect transition method. The Company is currently evaluating the amended guidance and the impact on its consolidated financial statements and related disclosures.

In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”), to provide clarification on cash flow classification related to eight specific issues including debt prepayment or debt extinguishment costs and contingent consideration payments made after a business combination. The guidance in ASU 2016-15 should be applied using a retrospective transition method to each period presented. ASU 2016-15 becomes effective for the Company in the first quarter of fiscal year 2018. The Company is currently evaluating the amended guidance and the impact on its consolidated financial statements and related disclosures.

In October 2016, the FASB issued ASU 2016-16, “Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory”(“ASU 2016-16”), which amends existing guidance to require entities to recognize income tax consequences of an intra-entity transfer of an asset, other than inventory, when the transfer occurs. ASU 2016-16 will be effective for the Company commencing in the first quarter of fiscal year 2018 using a modified retrospective method. The Company is currently evaluating the impact of this amended guidance; however, the provisions of ASU 2016-16 are not expected to have a significant impact on the Company’s consolidated financial statements and related disclosures.

In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash” (“ASU 2016-18”), which requires restricted cash and restricted cash equivalents to be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. Transfers between cash and cash equivalents and restricted cash or restricted cash equivalents are not reported as cash flow activities in the statement of cash flows. ASU 2016-18 will be effective for the Company in the first quarter of fiscal year 2018, using a retrospective transition method. The Company is currently evaluating the amended guidance and the impact on its consolidated financial statements and related disclosures.

In January 2017, the FASB issued ASU 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business” (“ASU 2017-01”), to clarify the definition of a business to assist entities with evaluating whether transactions should be accounted for as acquisitions of assets or businesses. ASU 2017-01 provides a screen to determine when an integrated set of assets and activities (collectively a “set”) is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. If the screen is not met, ASU 2017-01 requires that to be considered a business, a set must include an input and a substantive process that together significantly contribute to the ability to create output. ASU 2017-01 will be effective for the Company in the first quarter of fiscal year 2018, and should be applied prospectively. The Company is currently evaluating the amended guidance; however, the provisions of ASU 2017-01 are not expected to have a material impact on the Company's consolidated financial statements and related disclosures.

In May 2017, the FASB issued ASU 2017-09, “Compensation-Stock Compensation (Topic 718) - Scope of Modification” (“ASU 2017-09”), which provides clarity and reduces both diversity in practice and cost and complexity when applying the guidance in Topic 718 when there are changes to the terms or conditions of a share-based payment award. The amendments in ASU 2017-09 provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. ASU 2017-09 will be effective for the Company in the first quarter of fiscal year 2018 on a prospective basis. The Company is currently evaluating the amended guidance and the impact on its consolidated financial statements and related disclosures.

These transactions were accounted for by the acquisition method, and accordingly the results of operations were included in the Company’s consolidated financial statements from their respective acquisition dates.

Shemin Acquisition Accounting:

The Shemin transaction has been accounted for as a business combination using the acquisition method of accounting, whereby the purchase price was allocated to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values at the acquisition date, with the excess of purchase price over the estimated fair value of the net assets acquired recorded as goodwill. Transaction related costs incurred in connection with the Shemin acquisition were approximately $2.7 million. These level 3 fair value measurements have been determined based on assumptions that market participants would use in the pricing of the asset or liability. Independent third-party appraisers were engaged under the direction of management to perform valuation of certain tangible and intangible assets acquired and liabilities assumed.

The real and personal property was valued using the cost, market and income approaches. The income approach was utilized to estimate the fair value of the lease interests via the discounted cash flow methodology. Personal property was valued using the indirect method of the cost approach and the market approach. Using the indirect approach a reproduction cost of new personal property was determined from the historical cost.

Intangible assets separately valued in the transaction were customer relationships. Customer relationships were valued using the discounted cash flow method form of the income approach. After tax cash flow was discounted to present value using a 16.0% discount rate. Revenue growth was estimated based on long-term growth rates. Annual attrition was estimated at 10.0%.

The following table summarized the adjusted aggregate fair values of the assets acquired and liabilities assumed at the acquisition date of February 27, 2015 and subsequent adjustments. The estimate of the fair values of assets acquired and liabilities assumed is as follows (in millions):

Fair value of consideration transferred:
Cash consideration	$	57.8
Working capital adjustment	(0.1		)
Net consideration transferred	$	57.7
Assets acquired, at fair market value:
Cash and cash equivalents	$	2.3
Accounts receivable	5.7
Inventory	9.3
Deferred tax assets	3.5
Prepaid expenses and other current assets	2.2
Total current assets	23.0
Property and equipment	9.9
Intangible assets	27.2
Other assets	1.3
Total assets	$	61.4
Liabilities assumed, at fair market value:
Accounts payable	$	6.1
Accrued liabilities	6.7
Deferred tax liabilities	12.0
Total liabilities assumed	24.8
Identifiable net assets acquired	$	36.6
Goodwill	21.1
Net assets acquired	$	57.7

Goodwill is calculated as the excess of the purchase price over the estimated fair values of the assets acquired and the liabilities assumed in the acquisition, and represents the future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. The amount allocated to goodwill associated with the Shemin acquisition is primarily the result of anticipated synergies. None of the goodwill associated with this transaction will be deductible for income tax purposes.

On an unaudited pro forma basis, the following represents the consolidated results of the Company had the Company acquired Shemin as of December 29, 2014 (the first day of the Company’s fiscal year 2015):

(In millions, except for per share data)	January 3, 2016
Net sales	$	1,459.1
Net loss available to SiteOne common shareholders	$	(17.6	)
Net loss per share of common stock attributable to SiteOne - diluted	$	(1.24	)

The Company began consolidating the results of operations effective February 28, 2015. The acquisition added $130.6 million of net sales and $2.8 million of net income for the fiscal year ended January 1, 2017.

Employee Benefit and Stock Incentive Plans

Retirement Benefits [Abstract]

Employee Benefit and Stock Incentive Plans

Employee Benefit and Stock Incentive Plans

The Company sponsors a defined contribution benefit plan for substantially all of its employees. Company contributions to the plan are based on a percentage of employee wages. The Company’s contributions to the plan were approximately $6.4 million, $5.7 million and $4.2 million for the years ended December 31, 2017, January 1, 2017 and January 3, 2016, respectively.

Prior to the adoption of the Omnibus Equity Incentive Plan (the “Omnibus Incentive Plan”), as described below, the Company offered to key employees the ability to purchase common shares of the Company under a stock incentive plan (“Stock Incentive Plan”), which commenced in May 2014 as approved by the stockholders. Common stock options (“options”) were granted with the purchased shares at a predetermined number of options per purchased share. Prior to a public offering these shares were not transferrable except upon the employee’s death, repurchase at the option of the Company, or with the Company’s consent. The Stock Incentive Plan provided for drag-along and tag-along rights if the stockholders sold more than 50.01% of their shares prior to a public offering. As of the date of IPO, 762,079 shares were purchased by employees and outstanding under the Stock Incentive Plan. For the years ended December 31, 2017 and January 1, 2017 respectively, 0 shares and 11,036 shares were repurchased from certain terminated employees by the Company. The Company’s policy was to retain these repurchased shares as treasury shares and not to retire them.

The Company adopted the Omnibus Incentive Plan on April 28, 2016 in connection with the IPO. Upon the adoption of the Omnibus Incentive Plan, the Stock Incentive Plan terminated and no additional awards were made thereunder. However, awards previously granted under the Stock Incentive Plan were unaffected by the termination of the Stock Incentive Plan. Awards under the Omnibus Incentive Plan may be made in the form of stock options, which may be either incentive stock options or non-qualified stock options; stock purchase rights; restricted stock; restricted stock units (“RSUs”); performance shares; performance units; stock appreciation rights (“SARs”); dividend equivalents; deferred stock units (“DSUs”); and other stock-based awards. Any shares covered by an award, or any portion thereof, granted under the Omnibus Incentive Plan or Stock Incentive Plan that terminates, is forfeited, is repurchased, expires or lapses for any reason will again be available for the grant of awards. Additionally, any shares tendered or withheld to satisfy the grant or exercise price or tax withholding obligations pursuant to any award under the Omnibus Incentive Plan will again be available for issuance.

The Company granted 400,415 options, 19,346 DSUs and 49,323 RSUs; in addition, 53,732 options and RSUs were forfeited during the year ended December 31, 2017; and, the Company granted 223,970 options, 26,020 DSUs and 18,973 RSUs; in addition, 17,427 options were forfeited during the year ended January 1, 2017 under the Omnibus Incentive Plan. The RSUs and options granted to employees vest over a four-year period at 25 percent per year. The DSUs granted to non-employee directors vest immediately. Options and RSUs expire ten years after the date of grant. The compensation cost for options and RSUs is recognized on a straight-line basis over the requisite vesting period. The aggregate number of shares which may be issued under the Omnibus Incentive Plan is 2,000,000 shares of which 1,334,749 remain as of December 31, 2017.

The estimated grant-date fair value of stock options was calculated using the Black-Scholes option-pricing model, based on the following weighted-average assumptions:

	December 31, 2017	January 1, 2017	January 3, 2016
Risk-free interest rate	2.11%	1.43%	1.87%
Expected dividends	—	—	—
Expected volatility	30%	30%	36%
Expected term (in years)	6.25	6.25	6.50

Prior to the Company’s IPO, determining the fair value of the shares of common stock underlying stock options was historically based upon a valuation provided by a third-party valuation specialist. The Company’s approach to valuation, which required making complex and subjective judgments, was based on a combination of a discounted cash flow method of income approach and market approaches. The discounted cash flow method used estimates of revenue, driven by assumed market growth rates, and estimated costs as well as appropriate discount rates. These estimates were consistent with the plans and estimates that were used to manage the business. There was inherent uncertainty in making these estimates. Subsequent to the completion of the IPO, the Company uses the market closing price of its common stock as reported on the New York Stock Exchange to determine the fair value of the shares of common stock underlying stock options.

The fair value of each option award was estimated on the date of grant using the Black-Scholes options pricing model. Expected volatilities are based on the historical equity volatility of comparable publicly-traded companies. The expected term of options granted is derived from the output of the option valuation model and represents the period of time that options granted are expected to be outstanding. The risk-free rates utilized for periods throughout the contractual life of the options are based on the U.S. Treasury security yields at the time of grant.

ABL Facility:

SiteOne Landscape Supply Holding, LLC (“Landscape Holding”) and SiteOne Landscape Supply, LLC (“Landscape,” and together with Landscape Holding, the “Borrowers”), each an indirect wholly-owned subsidiary of the Company, entered into an amended credit agreement during 2015 (such agreement, as amended by the First Amendment to the Credit Agreement, dated June 13, 2014, the Second Amendment to the Credit Agreement, dated January 26, 2015, the Third Amendment to the Credit Agreement, dated February 13, 2015, and the Fourth Amendment to the Credit Agreement, dated October 20, 2015, the “ABL Credit Agreement”) providing for an asset-based credit facility (the “ABL Facility”) of up to $325.0 million, subject to borrowing base availability. The final maturity date of the ABL Facility is October 20, 2020. The ABL Facility is secured by a first lien on the inventory and receivables of the Borrowers. The ABL Facility is guaranteed by SiteOne Landscape Supply Bidco, Inc. (“Bidco”), an indirect wholly-owned subsidiary of the Company, and each direct and indirect wholly-owned U.S. restricted subsidiary of Landscape. The availability under the ABL Facility was $162.0 million and $164.5 million as of December 31, 2017 and January 1, 2017, respectively. Availability is determined using borrowing base calculations of eligible inventory and receivable balances less the current outstanding ABL Facility and letters of credit balances.

On May 24, 2017, the Company entered into the Omnibus Amendment (the “Omnibus Amendment”) which amends, among other things, the ABL Credit Agreement, in order to, among other things, update certain provisions relating to secured cash management and hedging obligations.

The interest rate on the ABL Facility is LIBOR plus an applicable margin ranging from 1.25% to 2.00% or an alternate base rate for U.S. denominated borrowings plus an applicable margin ranging from 0.25% to 1.00%. The interest rates on outstanding balances range from 3.25% to 3.32% and 2.49% to 4.50% as of December 31, 2017 and January 1, 2017, respectively. Additionally, the Borrowers pay a 0.250% and 0.375% commitment fee on the unfunded amount of as of December 31, 2017 and January 1, 2017, respectively.

The ABL Facility is subject to mandatory prepayments if the outstanding loans and letters of credit exceed either the aggregate revolving commitments of the current borrowing base, in an amount equal to such excess. Additionally, the credit facility is subject to various covenants requiring minimum financial ratios and additional borrowings may be limited by these financial ratios. Failure to meet any of these covenants could result in an event of default under these agreements. If an event of default occurs the lenders could elect to declare all amounts outstanding under these agreements to be immediately due and payable, enforce their interest in collateral pledged under the agreement, or restrict the Borrowers’ ability to obtain additional borrowings under these agreements.

The ABL Facility contains customary representations and warranties and customary affirmative and negative covenants which fully restrict retained earnings of the Borrowers. The negative covenants are limited to the following: fundamental changes, dividends and distributions, acquisitions, collateral, payments and modifications of restricted indebtedness, negative pledge clauses, changes in line of business, currency, commodity and other hedging transactions, transactions with affiliates, investments, limitations on indebtedness and liens. The negative covenants are subject to the customary exceptions and also permit the payment of dividends and distributions, investments, permitted acquisitions and payments or redemptions of junior indebtedness upon satisfaction of a payment condition. As of December 31, 2017, the Company is in compliance with all of the ABL Facility covenants.

Term Loan Facility:

The Borrowers entered into the Term Loan Facility dated April 29, 2016 in the amount of $275.0 million, and was amended on November 23, 2016 (see Term Loan Facility Amendments below). The Term Loan Facility is guaranteed by Bidco and each direct and indirect wholly-owned U.S. restricted subsidiary of Landscape. The Term Loan Facility has first lien on Property and equipment, Intangibles, and equity interests of Landscape, and second lien on ABL Facility assets. The final maturity date of the Term Loan Facility is April 29, 2022.

Refinancing:

On April 29, 2016, the Company refinanced its Prior Term Loan Facility with the Term Loan Facility. The proceeds under the Term Loan Facility were used to repay all $60.3 million of borrowings outstanding under the Prior Term Loan Facility, repay $29.9 million of borrowings outstanding under the ABL Facility, pay a special cash dividend of $176.0 million to existing holders of the Company’s common stock and Redeemable Convertible Preferred Stock (on an as-converted basis) as of April 29, 2016 and pay fees and expenses associated with the refinancing transaction.

Term Loan Facility Amendments:

On November 23, 2016, the Company amended the Term Loan Facility (the “First Amendment”) to, among other things, (i) add the Tranche B Term Loans under the Term Loan Facility in an aggregate principal amount of $273.6 million and (ii) increase the aggregate principal amount of Tranche B Term Loans under the Term Loan Facility to $298.6 million pursuant to an increase supplement. Proceeds of the Tranche B Term Loans were used to, among other things, (i) repay in full the term loans outstanding under the Existing Term Loans and (ii) repay $21.0 million of borrowings outstanding under the ABL Facility.

On May 24, 2017, the Company amended the Term Loan Facility (the “Second Amendment”) to, among other things, add an additional credit facility under the Term Loan Facility consisting of additional term loans (the “Tranche C Term Loans”) in an aggregate principal amount of $299.5 million. Proceeds of the Tranche C Term Loans were used to, among other things, repay in full the Tranche B Term Loans outstanding under the Term Loan Facility immediately prior to effectiveness of the Second Amendment and pay fees and expenses associated with the transaction.

On December 12, 2017, the Company amended the Term Loan Facility (the “Third Amendment”) to, among other things, (i) add an additional credit facility under the Term Loan Facility consisting of additional term loans (the “Tranche D Term Loans”) in an aggregate principal amount of $298.0 million and (ii) increase the aggregate principal amount of Tranche D Term Loans under the Term Loan Facility to $350.0 million. Proceeds of the Tranche D Term Loans were used to, among other things, (i) repay in full the Tranche C Term Loans and (ii) repay approximately $50.7 million of borrowings outstanding under the ABL Facility.

The Tranche D Term Loans bear interest, at Landscape Holding’s option, at either (i) an adjusted LIBOR rate plus an applicable margin equal to 2.75% or (ii) an alternative base rate plus an applicable margin equal to 1.75%. The other terms of the Tranche D Term Loans are generally the same as the terms applicable to the Existing Term Loans.The interest rate on the outstanding balance of the Term Loan Facility was 4.32% as of December 31, 2017.

The Term Loan Facility contains customary representations and warranties and customary affirmative and negative covenants, which fully restrict retained earnings of the Borrowers. The negative covenants are limited to the following: limitations on indebtedness, restricted payments, restrictive agreements, sales of assets and subsidiary stock, transactions with affiliates, liens, fundamental changes, amendments, lines of business and limitations on certain actions of the parent borrower. The negative covenants are subject to the customary exceptions.

The Term Loan Facility is subject to annual mandatory prepayments in an amount equal to 50% of excess cash flow, as defined in the Term Loan Credit Agreement, which information is hereby incorporated by reference, for the applicable fiscal year if the secured leverage ratio is greater than 3.00 to 1.00. As of December 31, 2017, the Company is in compliance with all of the Term Loan Facility covenants.

During the years ended December 31, 2017, January 1, 2017 and January 3, 2016, the Company incurred total interest expenses of $25.2 million, $22.1 million and $11.4 million, respectively, of which $21.8 million, $17.6 million and $6.9 million, respectively, related to interest on the ABL Facility and the Term Loan Facility. The debt issuance costs and discounts are amortized as interest expense over the life of the debt. As a result of the refinancing and amendments of the Term Loan Facility and ABL Facility, unamortized debt issuance costs and discounts in the amount of $0.1 million, $1.7 million and $1.2 million, were written off to expense, and new discounts and debt issuance costs of $2.2 million, $7.0 million and $1.0 million, were capitalized during the years ended December 31, 2017, January 1, 2017 and January 3, 2016, respectively. Amortization expense related to debt issuance costs and discounts was $3.0 million, $2.5 million and $3.0 million for the years ended December 31, 2017, January 1, 2017 and January 3, 2016, respectively. The remaining $0.3 million, $0.3 million and $0.3 million of interest is primarily related to capital leases, partially offset by purchase accounting adjustments for the years ended December 31, 2017, January 1, 2017 and January 3, 2016, respectively.

Interest Rate Swaps

The Company utilizes interest rate swap contracts to reduce its exposure to fluctuations in variable interest rates for future interest payments on its syndicated senior Term Loan Facility. In June 2017, the Company entered into two forward-starting interest rate swap contracts to convert the variable interest rate to a fixed interest rate on portions of the borrowings under the Term Loan Facility. The contracts are scheduled to become effective on March 11, 2019 and terminate on June 11, 2021. The following table provides additional details related to the swap contracts (in millions except fixed interest rate):

								Fair Value of Hedge Assets
Derivatives accounted for as hedges	Inception Date	Notional Amount		Fixed Interest Rate		Type of Hedge	Balance Sheet Classification	December 31, 2017		January 1, 2017
Forward-starting interest rate swap 1	June 30, 2017	$	58.0	2.1345	%	Cash flow	Other assets	$	0.2	$	—
Forward-starting interest rate swap 2	June 30, 2017	$	116.0	2.1510	%	Cash flow	Other assets	$	0.4	$	—

The Company recognizes the unrealized gains or unrealized losses as either assets or liabilities at fair value on its Consolidated Balance Sheets. As of December 31, 2017, the fair value changes of the forward-starting interest rate swaps in the amount of $0.6 million was recorded in Other assets.

The Company will recognize any differences between the variable interest rate payments and the fixed interest rate settlements with the swap counterparties as an adjustment to interest expense over the life of the swaps. The Company has designated these swaps as cash flow hedges and records the changes in the estimated fair value of the swaps to Accumulated other comprehensive income (loss) on its Consolidated Balance Sheets. As of December 31, 2017, the fair value changes of the forward-starting interest rate swaps in the amount of $0.6 million was recorded in Accumulated other comprehensive income (loss) as a component of other comprehensive income (loss). To the extent the interest rate swaps are determined to be ineffective, the Company recognizes the changes in the estimated fair value of the swaps in earnings. For the year ended December 31, 2017, there was no ineffectiveness recognized in earnings. The net amount of unrealized gain or loss on derivative instruments included in Accumulated other comprehensive income (loss) related to the forward-starting interest rate swap contracts maturing and expected to be realized during the next twelve months was zero as of December 31, 2017.

Failure of the swap counterparties to make payments would result in the loss of any potential benefit to the Company under the swap agreements. In this case, the Company would still be obligated to pay the variable interest payments underlying the debt agreements. Additionally, failure of the swap counterparties would not eliminate the Company’s obligation to continue to make payments under the existing swap agreements if it continues to be in a net pay position.

Income Taxes

Income Taxes

In December 2017, the Tax Cuts and Jobs Act (the “2017 Tax Act”) was enacted. The 2017 Tax Act includes a number of changes to existing U.S. tax laws that impact the Company, most notably a reduction of the U.S. corporate income tax rate from 35% to 21%, effective as of January 1, 2018. The 2017 Tax Act also provides for a one-time transition tax on certain foreign earnings that were previously deferred, immediate expensing for certain assets placed into service after September 27, 2017, and a Global intangible low-taxed income (“GILTI”) provision which requires U.S. income inclusion of foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary’s tangible assets.

The Company recognized the income tax effects of the 2017 Tax Act in its 2017 financial statements in accordance with Staff Accounting Bulletin No. 118 (“SAB 118”), which provides SEC staff guidance for the application of ASC Topic 740, Income Taxes, in the reporting period in which the 2017 Tax Act was signed into law. At December 31, 2017, the Company has not completed its accounting for the tax effects of enactment of the 2017 Tax Act; however, in certain instances, as described below, the Company has made a reasonable estimate (provisional amount) of the effects on its existing deferred tax balances and one-time transition tax. In other cases, the Company has not been able to make a reasonable estimate and continues to account for those items based on the existing accounting under ASC Topic 740, and the provisions of the tax laws that were in effect prior to enactment. For the items which the Company was able to determine a reasonable estimate, a provisional benefit of $3.2 million was recognized, as described below, which is included as a component of income tax expense from continuing operations. In all cases, the Company will continue to make and refine its calculations as additional analysis is completed. Moreover, the Company’s provisional estimates may also be affected as it gains a more thorough understanding of the 2017 Tax Act. Finally, the Company is evaluating whether it will be subject to incremental U.S. tax on GILTI, beginning in 2018, due to expense allocations required under the U.S. foreign tax credit rules. The Company has provisionally elected to account for GILTI tax in the period in which it is incurred, and therefore, has not provided any provisional deferred tax impacts of GILTI in its consolidated financial statements for the year ended December 31, 2017.

Provisional amounts

Deferred tax assets and liabilities - the Company re-measured certain deferred tax assets and liabilities based on the rates at which these items are expected to reverse in the future, which is 21%. However, the Company is still analyzing certain aspects of the 2017 Tax Act and refining its calculations, which potentially could affect the measurement of these balances or potentially give rise to new deferred tax amounts. The provisional amount recorded related to the re-measurement of the Company’s deferred tax balance was a benefit of $4.5 million.

Foreign tax effects - the one-time transition tax is based on the Company’s total post-1986 earnings and profits (“E&P”) that were previously deferred from U.S. income taxes. The Company recorded a provisional amount for the one-time transition tax liability on E&P from its Canadian subsidiary, resulting in an increase in income tax expense of $1.3 million.  The Company has not yet completed its calculation of the total post-1986 E&P for the Canadian subsidiary. Further, the transition tax is based in part on the amount of those earnings held in cash and other specified assets. This amount may change when the Company finalizes its calculation of post-1986 foreign E&P previously deferred from U.S. federal taxation, and finalizes the amounts held in cash or other specified assets.

Historically, U.S. income tax has not been recognized on the excess of the amount for financial reporting over the tax basis of the Company’s investment in its Canadian subsidiary caused by foreign earnings that are indefinitely reinvested outside the U.S.  At December 31, 2017, unremitted earnings of the Canadian subsidiary have been included in the computation of the transition tax associated with the 2017 Tax Act.  The Company remains indefinitely reinvested with respect to its initial investment and any associated potential withholding tax on earnings of its Canadian subsidiary subject to the transition tax, as well as with respect to future earnings that will primarily fund the operations of the subsidiary; however, the Company continues to evaluate its position under SAB 118.

Deferred income taxes reflect the expected future tax consequences of temporary differences between the financial statement carrying amount of the Company’s assets and liabilities, tax credits, and loss carry forwards. The significant components of deferred income taxes are as follows (in millions):

	December 31, 2017			January 1, 2017
Deferred tax assets:
Net operating losses	$	5.2		$	4.1

The Company evaluates its deferred tax assets to determine the need for a valuation allowance, and to conclude whether it is more likely than not that those deferred income tax assets will be realized. Management assesses the available positive and negative evidence to establish whether sufficient future taxable income will be generated to permit use of the existing deferred tax assets. On the basis of this evaluation, as of December 31, 2017 and January 1, 2017, a valuation allowance of $5.2 million and $4.1 million, respectively, has been recorded against deferred tax assets related primarily to state net operating loss carryforwards for separate returns the Company believes are more likely than not to expire unused. Activity within the tax valuation allowance for the periods was as follows (in millions):

	For the year January 2, 2017 to December 31, 2017		For the year January 4, 2016 to January 1, 2017			For the year December 29, 2014 to January 3, 2016

Increase in valuation allowance	1.1		—			—
Decrease in valuation allowance	—		(0.1		)	(0.4		)
Ending balance	$	5.2	$	4.1		$	4.2

As of December 31, 2017, the Company had available tax-effected state NOL carryforwards of approximately $5.2 million that will expire at various dates from 2017 through 2028, if not utilized.

The Company recognizes the tax effects of uncertain tax positions only if such positions are more likely than not to be sustained based solely upon its technical merits at the reporting date. The Company refers to the difference between the tax benefit recognized in its financial statements and the tax benefit claimed in the income tax return as an unrecognized tax benefit. There was no expense or liability recorded for unrecognized tax benefits for each period presented. The Company does not expect that the unrecognized tax benefit will materially change over the next 12 months.

The Company’s policy for recording interest and penalties, if any, associated with uncertain tax positions is to recognize interest within the Interest and other non-operating expenses line item, and to recognize penalties in Selling, general and administrative expenses. For each period presented, the Company had no accrued interest or penalties related to uncertain tax positions.

The Company is subject to U.S. federal income tax, income tax in multiple state jurisdictions, and Canadian federal and provincial income tax with respect to its foreign subsidiary. With limited exceptions, years prior to 2009 are no longer open to federal, state and local examination by taxing authorities. As part of the Deere consolidated federal return audit, the Company is currently under audit for federal income tax years 2009 through 2013. The Company is also under audit by a number of state and local jurisdictions; however, no audit adjustments are anticipated that would result in a material change to the Company’s financial position.

Deere has indemnified the Company against any taxes, penalties or interest for tax periods prior to the CD&R Acquisition, accruing after the CD&R Acquisition date.

Related Party Transactions

Following consummation of the secondary offering on July 26, 2017 (as described in Note 1), CD&R and Deere no longer have an ownership interest in the Company. Transactions with customers and entities that were under the common ownership of CD&R and Deere through July 26, 2017 are considered related-party transactions and are discussed below.

The Company offers a financing plan to its customers through John Deere Financial, f.s.b. (“John Deere Financial”) a wholly-owned subsidiary of Deere. The Company pays John Deere Financial a fee related to the financing offered, which was approximately $0.3 million, $0.5 million and $0.3 million for the period from January 2, 2017 through July 26, 2017 and for the years ended January 1, 2017, and January 3, 2016, respectively.

In connection with the CD&R Acquisition, the Company entered into consulting agreements (the “Consulting Agreements”) with each of CD&R and Deere. CD&R and Deere each provided consulting services under the Consulting Agreements at an annual fee of approximately $1.3 million and $0.7 million plus expense reimbursement for a 10 year term or earlier termination if CD&R’s or Deere’s ownership, respectively, of the Company was reduced below 10%. On May 17, 2016, the Company entered into termination agreements with CD&R and Deere pursuant to which the Company paid CD&R and Deere an aggregate fee of approximately $7.5 million to terminate the Consulting Agreements in connection with the consummation of the IPO. See “Note 11. Redeemable Convertible Preferred Stock” for a discussion of dividends paid to the CD&R investor.

TruGreen is a customer under common ownership of CD&R and therefore became a related party at the time of the CD&R Acquisition. As provided above, TruGreen is no longer a related party as a result of the consummation of the secondary offering on July 26, 2017. Net sales included in the Company’s Consolidated Statement of Operations with TruGreen were $4.3 million for the period from January 2, 2017 through July 26, 2017 and $3.9 million for the year ended January 1, 2017. Accounts receivable included in the Company’s consolidated balance sheets was $0.4 million as of January 1, 2017.

The Company believes the reasonably possible range of losses for these unresolved legal actions in addition to amounts accrued would not have a material effect on the Company’s assets and liabilities as of December 31, 2017 and January 1, 2017 and revenues, expenses, changes in equity, and cash flows for the years ended December 31, 2017, January 1, 2017, and January 3, 2016.

Environmental liability: As part of the sale of LESCO manufacturing assets in 2005, the Company retained the environmental liability associated with those assets. Remediation activities can vary substantially in duration and cost and it is difficult to develop precise estimates of future site remediation costs. The Company estimated in accrued liabilities the undiscounted cost of future remediation efforts to be approximately $3.8 million and $4.0 million as of December 31, 2017 and January 1, 2017, respectively. As part of the CD&R Acquisition, Deere agreed to pay the first $2.5 million of the liability and cap the Company exposure to approximately $2.4 million. The Company has an indemnification asset against the liability as a result of these actions of $1.4 million and $1.6 million as of December 31, 2017 and January 1, 2017, respectively.

Letter of credit: As of December 31, 2017 and January 1, 2017, outstanding letters of credit were $4.5 million and $2.9 million respectively. There were no amounts drawn on the letters of credit for either period presented.

Purchase commitments: The Company has entered into contracts with various farmers that obligate the Company to purchase certain nursery products and grass seeds. These contracts run through fiscal year 2021. The total future obligation was approximately $58.8 million as of December 31, 2017 with expected payments of approximately $33.1 million, $16.1 million, $8.9 million, $0.7 million and $0.0 million during the years ending December 2018, 2019, 2020, 2021 and 2022, respectively. The Company’s purchases were approximately $33.7 million, $28.1 million and $20.4 million for the years ended December 31, 2017, January 1, 2017 and January 3, 2016, respectively. In addition, the Company has entered into various service commitments and definitive agreements to acquire an entity or group of assets; of which, the maximum total future obligation was approximately $9.4 million as of December 31, 2017.

Operating leases: The Company leases buildings and equipment under certain non-cancelable operating leases that expire in various periods through December 2022. Rent expense under operating leases was approximately $48.2 million, $43.5 million and $37.3 million during the years ended December 31, 2017, January 1, 2017 and January 3, 2016, respectively. Certain leases have been subleased to third parties.

Approximate future minimum lease payments under non-cancelable operating leases, net of sublease income, are as follows (in millions):

	Gross lease payments		Sublease Income			Net lease payments
Fiscal year:
2018	$	46.1	$	(0.1	)	$	46.0
2019	38.9		(0.1		)	38.8
2020	30.2		—			30.2
2021	23.5		—			23.5
2022	16.1		—			16.1
Thereafter	72.5		—			72.5
Total minimum lease payments	$	227.3	$	(0.2	)	$	227.1

During the past several years the Company has closed locations under operating leases. The remaining lease payments are accrued and included in accrued liabilities and other long-term liabilities. The aggregate reserve liability was approximately $0.3 million and $0.0 million at December 31, 2017 and January 1, 2017, respectively.

Redeemable Convertible Preferred Stock

12 Months Ended

Dec. 31, 2017

Temporary Equity Disclosure [Abstract]

Redeemable Convertible Preferred Stock

Redeemable Convertible Preferred Stock

The CD&R Equity Investment

In connection with the CD&R Acquisition, the Company issued Redeemable Convertible Preferred Stock to the CD&R Investor. On the day prior to the closing of the IPO, all of the then-outstanding Redeemable Convertible Preferred Stock converted into shares of common stock, resulting in the issuance by the Company of an additional 25,303,164 shares of common stock.

Accounting for the Redeemable Convertible Preferred Stock

In accordance with the SEC guidance within ASC Topic 480, Distinguishing Liabilities from Equity: Classification and Measurement of Redeemable Securities, the Company classified the Redeemable Convertible Preferred Stock as mezzanine equity because the Redeemable Convertible Preferred Stock contained a redemption feature which was contingent upon certain change of control events, the occurrence of which was not solely within the control of the Company. These contingent events were not considered probable of occurring and as such the Company did not accrete the mezzanine equity to its redemption value each period. The Company determined that none of the features included in the Redeemable Convertible Preferred Stock were required to be accounted for separately as a derivative under ASC Topic 815, Derivatives and Hedging.

The initial issuance of Redeemable Convertible Preferred Stock did not include a beneficial conversion feature (“BCF”) because the conversion price used to set the conversion ratio at the time of issuance was greater than the initial common stock price. The paid-in-kind dividends in the form of Redeemable Convertible Preferred Stock contained the same conversion price as the original issuance and in certain cases did include a BCF as of the dividend payment date. Since the Redeemable Convertible Preferred Stock did not have a fixed or determinable redemption date and was freely convertible at any time, the Company immediately amortized any BCF recognized through retained earnings. As disclosed in Note 1, on May 2, 2016, the Company paid a one-time special cash dividend to all existing stockholders as of April 29, 2016. CD&R Investor received $112.4 million in accordance with its right to participate in all distributions to common stock on an as-converted basis, in accordance with its right as a preferred stockholder. The Redeemable Convertible Preferred Stock converted to common stock in accordance with its terms on May 16, 2016. During the year ended January 1, 2017, the Company paid the cumulative dividends in cash; and accordingly, no BCF was recognized.

The below table summarizes the changes in the carrying value of the Redeemable Convertible Preferred Stock (in millions):

Earnings (Loss) Per Share

12 Months Ended

Dec. 31, 2017

Earnings Per Share [Abstract]

Earnings (Loss) Per Share

Earnings (Loss) Per Share

Basic earnings (loss) per common share is computed by dividing net income (loss) attributable to common shares by the weighted average number of common shares outstanding for the period. The Redeemable Convertible Preferred Stock had the right to participate in all distributions declared and paid on the Company’s common stock on an as-converted basis, and was therefore considered a participating security. The Company calculates basic earnings per share using the “two-class” method, and for the years ended January 1, 2017 and January 3, 2016 did not allocate the loss available to common stockholders to the Redeemable Convertible Preferred Stock as those holders did not have a contractual obligation to share in net losses. In periods with income available to common stockholders, the Company would reduce income available to common stockholders to reflect the hypothetical distribution of undistributed earnings to the Redeemable Convertible Preferred Stock in accordance with its contractual rights. The Company reduced income available to common stockholders and increased loss attributable to common stockholders to reflect the cumulative dividend on the Company’s Redeemable Convertible Preferred Stock whether or not declared or paid during the period. Similarly, the Company reduced income available to common stockholders and increased loss attributable to common stockholders for any amortization of beneficial conversion features recorded during each period. See Note 11 for a detailed description of the terms of the Redeemable Convertible Preferred Stock.

As disclosed in Note 1, on May 2, 2016, a one-time special cash dividend of $176.0 million was paid to existing stockholders of the Company as of April 29, 2016. Of the $176.0 million special cash dividend, $112.4 million was paid to holders of the Redeemable Convertible Preferred Stock in accordance with its right to participate in all distributions to common stockholders on an as-converted basis. Prior to May 16, 2016, the earnings (loss) per share calculation reflected the impact of the Redeemable Convertible Preferred Stock. Since the special cash dividend was paid prior to conversion of the Redeemable Convertible Preferred Stock, the $112.4 million is reported as a reduction of net income attributable to common shares during the year ended January 1, 2017.

The Company’s computation of diluted earnings (loss) per common share includes the effect of potential common stock, if dilutive. For the years ended December 31, 2017, January 1, 2017 and January 3, 2016, the assumed exercises the Company’s employee stock options, RSUs and DSUs and the conversion of Redeemable Convertible Preferred Stock were anti-dilutive and, therefore, the following potential shares of common stock were not included in the diluted loss per common share calculation:

	December 31, 2017	January 1, 2017	January 3, 2016
Weighted average potential common shares excluded because anti-dilutive
Redeemable Convertible Preferred Stock	—	9,202,870	23,876,230
Employee Stock Options	13,798	3,160,457	2,836,919

Certain of the Company’s employee stock options, RSUs and DSUs were dilutive and resulted in additional potential common shares included in the Company’s calculation of diluted earnings per common share of 2,438,835, 0 and 0 for the years ended December 31, 2017, January 1, 2017 and January 3, 2016, respectively.

Notes to Condensed Parent Company Only Financial Statements

Note 1. Description of SiteOne Landscape Supply, Inc.

SiteOne Landscape Supply, Inc. (“Holdings” or the “Parent”) indirectly owns 100% of the membership interest in SiteOne Landscape Supply Holding, LLC (“Landscape Holding” or “subsidiary”), which it acquired from Deere & Company on December 23, 2013 (the “Closing Date”) in exchange for its common stock initially representing 40% of the outstanding capital stock (on an as-converted basis). In addition, Holdings issued cumulative convertible participating redeemable preferred stock (“Redeemable Convertible Preferred Stock”) to Clayton, Dubilier & Rice, LLC (“CD&R”) initially representing 60% of its remaining outstanding capital stock (on an as-converted basis) (both events collectively referred to herein as the “CD&R Acquisition”). On May 2, 2016, Holdings paid a one-time special cash dividend to all existing stockholders as of April 29, 2016. CD&R received $112.4 million in accordance with its right to participate in all distributions to common stock on an as-converted basis, in accordance with its right as a preferred stockholder. On the day prior to the closing of the initial public offering, all of the then-outstanding Redeemable Convertible Preferred Stock converted into shares of common stock, resulting in the issuance by Holdings of an additional 25,303,164 shares of common stock. On December 5, 2016, May 1, 2017 and July 26, 2017, Holdings completed secondary offerings of its common stock in which Deere and CD&R were the sole sellers. Following consummation of the secondary offering on July 26, 2017 , CD&R and Deere no longer have an ownership interest in Holdings. Holdings has no significant operations or assets other than its indirect ownership of the equity of Landscape Holding. Accordingly, the Holdings is dependent upon distributions from Landscape Holding to fund its obligations. However, under the terms of Landscape Holding’s credit agreements governing Landscape Holding’s ABL Facility and Term Loan Facility, Landscape Holding’s ability to pay dividends or lend to Holdings is restricted. Landscape Holding has no obligation to pay dividends to Holdings except to pay specified amounts to Holdings in order to fund the payment of Holdings’ tax obligations.

Note 2. Basis of Presentation

The accompanying Condensed Parent Only Financial Statements include the amounts of Holdings and its investment in subsidiary since the Closing Date under the equity method, and do not present the financial statements of Holdings and its subsidiary on a consolidated basis. Under the equity method, investment in subsidiary is stated at cost plus contributions and equity in undistributed income (loss) of subsidiary less distributions received since the date of acquisition. These condensed Parent Company Only Financial Statements should be read in conjunction with SiteOne Landscape Supply, Inc. Consolidated Financial Statements and their accompanying Notes to Consolidated Financial Statements.

Note 3. Income Taxes

With respect to the CD&R Acquisition, $9.8 million of transaction expenses were recorded within the period ended December 29, 2013. Of the $9.8 million of transaction expenses, $3.7 million were not deductible for tax purposes, and the remaining $6.1 million ($2.2 million tax-effected) were capitalized for tax purposes as a deferred tax asset. During the years end December 31, 2017 and January 1, 2017, respectively, $0.4 million ($0.2 million tax-effected) and $0.4 million ($0.1 million tax-effected) has been amortized, which gives rise to a net operating loss and current tax benefit that offsets the deferred tax expense by the same amount.

In December 2017, the Tax Cuts and Jobs Act (the “2017 Tax Act”) was enacted. The 2017 Tax Act includes a number of changes to existing U.S. tax laws that impact the Company, most notably a reduction of the U.S. corporate income tax rate from 35% to 21%, effective as of January 1, 2018. As a result, the Company re-measured its deferred tax asset based on the rates at which this item is expected to reverse in the future, which is 21%. The Company recognized the income tax effects of the 2017 Tax Act in its 2017 financial statements in accordance with Staff Accounting Bulletin No. 118, which provides SEC staff guidance for the application of ASC Topic 740, Income Taxes, in the reporting period in which the 2017 Tax Act was signed into law. At December 31, 2017, the Company has not completed its accounting for the tax effects of enactment of the 2017 Tax Act; however, the Company has made a reasonable estimate (provisional amount) of the effect on its existing deferred tax asset. The Company is still analyzing certain aspects of the 2017 Tax Act and refining its calculations, which potentially could affect the measurement of this balance or potentially give rise to new deferred tax amounts. The provisional amount recorded related to the re-measurement of our deferred tax asset was an expense of $0.6 million. As of December 31, 2017, the deferred tax asset related to these transaction expenses has a balance of $1.0 million.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of financial statement presentation

Basis of financial statement presentation:

SiteOne Landscape Supply, Inc. (hereinafter, collectively with all its consolidated subsidiaries, referred to as the “Company” or individually as “Holdings”) indirectly owns 100% of the membership interest in SiteOne Landscape Supply Holding, LLC (referred to herein as “Landscape Holding”). Landscape Holding is parent and sole owner of SiteOne Landscape Supply, LLC (referred to herein as “Landscape”). Prior to the transaction described below, Deere & Company (“Deere”) was the sole owner of SiteOne Landscape Supply Holding, LLC.

On December 23, 2013 (the “Closing Date”), the Company acquired 100% of the ownership interest in Landscape Holding from Deere in exchange for common shares of the Company initially representing 40% of the outstanding capital stock (on an as-converted basis) plus cash consideration of approximately $314 million, net of pre-closing and post-closing adjustments. In order to facilitate the transaction, the Company issued cumulative convertible participating redeemable preferred stock (“Redeemable Convertible Preferred Stock”) to Clayton, Dubilier & Rice, LLC (“CD&R”) for total consideration of $174 million initially representing 60% of the outstanding capital stock (on an as-converted basis). As part of the same transaction, Landscape Holding also acquired from Deere the affiliated company LESCO, Inc. (“LESCO”). The Company continues to be the sole owner of Landscape Holding. The aforementioned transactions described in this paragraph are referred to herein as the “CD&R Acquisition”.

Following consummation of the secondary offering on July 26, 2017, CD&R and Deere no longer have an ownership interest in the Company.

The Company’s chief operating decision maker (“CODM”) manages the business as a single reportable segment. Within the organizational framework, the same operational resources support multiple geographical regions and performance is evaluated primarily by the CODM at a consolidated level. The CODM also evaluates regional performance based on financial and operational measures and receives discrete financial information on a regional basis. Since all of the Company’s regions have similar operations and share similar economic characteristics, the Company aggregates regions into a single operating and reportable segment. These similarities include 1) long-term financial performance, 2) the nature of products and services, 3) the types of customers the Company sells to and 4) the distribution methods used. Further, all of the Company’s product categories have similar supply chain processes, classes of customers and economic characteristics.

The accompanying audited financial statements of the Company included herein have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”).

The Consolidated Statements of Operations, Comprehensive income (loss), Equity and Cash Flows for the Company are presented for the fiscal years ended December 31, 2017, January 1, 2017 and January 3, 2016. The consolidated financial statements for the Company include the assets and liabilities used in operating the Company’s business, including entities in which the Company owns or controls more than 50% of the voting shares. The Company owns 100% of all subsidiaries presented in these financial statements. All intercompany balances and transactions have been eliminated in consolidation.

Use of estimates in the preparation of financial statements

Use of estimates in the preparation of financial statements: The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Fiscal year

Fiscal year: The Company’s fiscal year is a 52- or 53-week period ending on the Sunday nearest to December 31. The year ended December 31, 2017 includes 52 weeks. The year ended January 1, 2017 includes 52 weeks. The year ended January 3, 2016 includes 53 weeks.

Cash and cash equivalents

Cash and cash equivalents: Cash and cash equivalents include primarily cash on deposit with banks which, at times, may exceed federally insured limits. The Company has not experienced any losses in these accounts. Cash and cash equivalents also include unsettled credit card transactions.

Accounts receivables

Accounts receivable: The Company carries accounts receivable at the original invoice amount less any charge-offs and the allowance for credit losses and doubtful accounts. Allowances for credit losses and doubtful accounts are maintained in amounts considered to be appropriate in relation to the receivables outstanding based on collection experience, economic conditions and credit risk quality. Receivables are written-off to the allowance when an account is considered uncollectible.

Inventory

Inventory: The majority of the Company’s inventories are valued at the lower of cost or net realizable value, with cost determined by the first-in, first-out (“FIFO”) method. Inventory is primarily considered to be finished goods. The Company establishes a reserve for excess, slow-moving, and obsolete inventory that is equal to the difference between the cost and estimated net realizable value for that inventory. These reserves are based on a review of planned and historical sales.

Property and equipment, net

Property and equipment, net: Property and equipment is stated at cost less accumulated depreciation. Depreciation is computed on property and equipment using the straight-line method over the estimated useful lives of the assets, as noted below. Leasehold improvements are depreciated over the lesser of their estimated useful lives or the remaining lease terms. Depreciation on property and equipment under capital lease is included in depreciation expense. Expenditures for replacement or major renewals of significant items are capitalized. Expenditures for maintenance, repairs and minor renewals are generally charged to expense as incurred.

Acquisitions

Acquisitions: When the Company acquires a controlling financial interest in an entity or group of assets that are determined to meet the definition of a business, the acquisition method described in ASC Topic 805, Business Combinations, is applied. The Company allocates the purchase consideration paid to acquire the business to the assets and liabilities acquired based on estimated fair values at the acquisition date, with the excess of purchase price over the estimated fair value of the net assets acquired recorded as goodwill. If during the measurement period (a period not to exceed 12 months from the acquisition date) the Company receives additional information that existed as of the acquisition date but at the time of the original allocation described above was unknown, the Company makes the appropriate adjustment to the purchase price allocation in the reporting period in which the adjustment is identified.

Goodwill impairment

Goodwill impairment: Goodwill represents the acquired fair value of a business in excess of the fair values of tangible and identified intangible assets acquired and liabilities assumed. The Company tests goodwill on an annual basis as of July fiscal month end and additionally if an event occurs or circumstances change that would indicate the carrying amount may be impaired. Examples of such indicators include a significant change in the business climate, unexpected competition, loss of key personnel or a decline in the Company’s market capitalization below the Company’s net book value. The Company performs impairment assessments at the reporting unit level, which is defined as an operating segment or one level below an operating segment, also known as a component.

Intangible assets, net

Intangible assets, net: Intangible assets include customer relationships, and trademarks and other, acquired through acquisitions. Intangibles assets with finite useful lives are amortized on an accelerated method or a straight-line of amortization over their estimated useful lives. An accelerated amortization method reflecting the pattern in which the asset will be consumed is utilized if that pattern can be reliably determined. If that pattern cannot be reliably determined, a straight-line amortization method is used. The Company considers the period of expected cash flows and underlying data used to measure the fair value of the intangible assets when selecting a useful life.

Fair value measurement

Fair value measurement: Fair value is defined as an exit price, representing an amount that would be received to sell an asset or the amount paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The inputs used to measure fair value are prioritized into the following three-tiered value hierarchy:

• Level 1: Unadjusted quoted prices in active markets for identical assets or liabilities.

• Level 2: Unadjusted quoted prices in active markets for similar assets or liabilities, unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active or inputs, other than quoted prices in active markets, which are observable either directly or indirectly.

• Level 3: Unobservable inputs for which there is little or no market data.

The hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. The classification of fair value measurement within the hierarchy is based upon the lowest level of input that is significant to the measurement.

The Company’s financial instruments consist of cash and cash equivalents, accounts receivables, forward-starting interest rate swap contracts and long-term debt. The variable interest rate on the long-term debt is reflective of current market borrowing rates. As such, the Company has determined that the carrying value of these financial instruments approximates fair value.

Revenue recognition

Revenue recognition: The Company recognize revenue when the following four basic criteria are met: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services have been rendered; (3) the price to the buyer is fixed or determinable; and (4) collectability is reasonably assured.

Sales of products are recorded when the sales price is determinable and the risks and rewards of ownership are transferred to independent parties. This transfer occurs primarily when goods are picked up by a customer at the branch or when goods are delivered to a customer location. In all cases, when a sale is recorded by the Company, no significant uncertainty exists surrounding the purchaser’s obligation to pay. Returns are estimated and accrued at the time a sale is recognized. The Company makes appropriate provisions based on experience for costs such as doubtful receivables and sales incentives. The Company also has entered into agency agreements with certain of its suppliers whereby the Company operates as a sales agent of those suppliers. The suppliers retain title to their merchandise until it is sold by the Company and determine the prices at which the Company can sell the suppliers’ merchandise. As such, the Company recognizes these agency sales on a net basis and records only the product margin as commission revenue within Net sales.

Sales incentives

Sales incentives: The Company offers certain customers rebates which are accrued based on sales volumes. In addition, the Company offers a points-based reward program whereby reward points can be redeemed for merchandise or credit on account (such as gift cards or vacation trips). The Company accrues a liability for this program based on sales volumes and an estimate of points that will be redeemed before expiration. Liabilities for these sales incentives are included in Accrued Liabilities.

Sales taxes

Sales taxes: The Company collects and remits taxes assessed by different governmental authorities that are both imposed on and concurrent with revenue producing transactions between the Company and its customers. These taxes may include sales, use, value-added and some excise taxes. The Company reports the collection of these taxes on a net basis (excluded from sales).

Cost of goods sold

Cost of goods sold: Cost of goods sold includes all inventory costs, such as purchase price from suppliers, net of any rebates received, as well as inbound freight and handling, and other costs associated with the inventory and is exclusive of the cost to deliver the products to customers.

Shipping and handling costs

Shipping and handling costs: Shipping and handling costs associated with inbound freight are included in Cost of goods sold.

Warranty reserves

Warranty Reserves: Provisions for estimated warranty costs for the return of nursery product are provided for in the same period the related sales are recorded. The Company offers product warranties on selected nursery items. The warranty reserve is based on historical and current trends.

Advertising costs

Advertising costs are charged to expense as incurred and were approximately $2.1 million, $0.9 million, and $0.4 million, during the years ended December 31, 2017, January 1, 2017 and January 3, 2016, respectively.

Stock-based compensation

Stock-based compensation: The Company applies the fair value method to recognize compensation expense for stock-based awards. Using this method, the estimated grant-date fair value of the award is recognized on a straight-line basis over the requisite service period based on the portion of the award that is expected to vest.

Stock-based compensation expense for restricted stock units is measured based on the fair value of the Company’s common stock on the grant date. The Company utilizes the Black-Scholes option pricing model to estimate the grant-date fair value of option awards. The exercise price of option awards is set to equal the estimated fair value of the common stock at the date of the grant. The following weighted-average assumptions are also used to calculate the estimated fair value of option awards:

• Expected volatility: The expected volatility of the Company’s shares is estimated using the historical stock price volatility over the most recent period commensurate with the estimated expected term of the awards.

• Expected term: For employee stock option awards, the Company determines the weighted average expected term equal to the weighted period between the vesting period and the contract life of all outstanding options.

• Dividend yield: The Company has not paid dividends and does not anticipate paying a cash dividend in the foreseeable future and, accordingly, uses an expected dividend yield of zero.

• Risk-free interest rate: The Company bases the risk-free interest rate on the implied yield available on a U.S. Treasury note with a term equal to the estimated expected term of the awards.

Other income

Other income: Other income consists primarily of financing charges and net gain/loss on sale of assets.

Income taxes

Income taxes: The Company files a consolidated federal income tax return and files both combined or unitary state income tax returns as well as separate state income tax returns in certain jurisdictions.

Deferred taxes are provided on an asset and liability method in which deferred tax assets are recognized for deductible temporary differences and operating loss and tax credit carry forwards, and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax basis. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment. Realization of deferred tax assets is dependent upon sufficient future taxable income.

The Company’s operations involve dealing with uncertainties and judgments in the application of complex tax regulations in a multitude of jurisdictions. The Company reports a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return based on its estimate of whether, and the extent to which, additional taxes will be due. The Company recognizes interest, if any, related to unrecognized tax benefits within the Interest and other non-operating expenses line item, and recognizes penalties in Selling, general and administrative expenses.

In December 2017, the Tax Cuts and Jobs Act (the “2017 Tax Act”) was enacted. The 2017 Tax Act includes a number of changes to existing U.S. tax laws that impact the Company, most notably a reduction of the U.S. corporate income tax rate from 35% to 21%, which required the Company to re-measure certain deferred tax assets and liabilities in the reporting period in which the 2017 Tax Act was signed into law, a one-time transition tax on certain foreign earnings that were previously deferred, and immediate expensing for certain assets placed into service after September 27, 2017. The Company recognized the income tax effects of the 2017 Tax Act in its 2017 financial statements in accordance with Staff Accounting Bulletin No. 118, which provides SEC staff guidance for the application of ASC Topic 740, Income Taxes. At December 31, 2017, the Company has not completed its accounting for the tax effects of enactment of the 2017 Tax Act. In certain instances, however, the Company has made a reasonable estimate (provisional amount) of the effects with respect to existing deferred tax balances and the one-time transition tax. In other cases, the Company has not been able to make a reasonable estimate and continues to account for those items based on existing accounting under ASC Topic 740, and the provisions of the tax laws that were in effect prior to enactment. In all cases, the Company will continue to make and refine its calculations as additional analysis is completed, and provisional estimates may also be affected as the Company gains a more thorough understanding of the 2017 Tax Act. See Note 8 for further information pertaining to income taxes.

Foreign currency translation

Foreign currency translation: The functional currency for the Company’s Canadian operations is the Canadian dollar, the local currency. The assets and liabilities of these operations are translated into U.S. dollars at the end of the period exchange rates. The revenues and expenses are translated at average exchange rates for the period. The gains or losses from these translations are recorded in other comprehensive income (loss). Gains or losses recognized on transactions denominated in a currency other than the functional currency are included in net income (loss).

Beneficial conversion features

Beneficial conversion features: The Company had issued Redeemable Convertible Preferred Stock with dividends that were paid-in-kind during the years ended January 3, 2016 and December 28, 2014. The Company recorded paid-in-kind dividends at carrying value on the issuance date. The paid-in-kind dividends in the form of Redeemable Convertible Preferred Stock contained the same conversion rate as the Redeemable Convertible Preferred Stock issued on the Closing Date. For certain Redeemable Convertible Preferred Stock issued as dividends paid-in-kind, the stated conversion price was determined to be less than the common stock price as of the dividend payment date resulting in the recognition of a beneficial conversion feature (“BCF”) in additional paid-in capital. Since the Redeemable Convertible Preferred Stock did not have a fixed or determinable redemption date and was readily convertible at any time, the Company immediately amortized any BCF recognized through retained earnings. The Redeemable Convertible Preferred Stock converted to common stock in accordance to its terms on May 16, 2016.

Recently Issued and Adopted Accounting Pronouncements and Accounting Pronouncements Issued But Not Yet Adopted

Recently Issued and Adopted Accounting Pronouncements

In September 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-16, Business Combinations, an update to the existing guidance under the Business Combinations topic. This update simplifies the accounting for measurement-period adjustments. The amendments in this update require that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. This update will be effective for all annual and interim periods beginning after December 15, 2015. The amendments in this update should be applied prospectively to adjustments to provisional amounts that occur after the effective date of this update with earlier application permitted for financial statements that have not been issued. The adoption of this update did not have a material impact on the Company’s consolidated financial statements.

In July 2015, the FASB issued ASU 2015-11, “Inventory (Topic 330): Simplifying the Measurement of Inventory” (“ASU 2015-11”), which requires entities to measure inventory at the lower of cost or net realizable value rather than at the lower of cost or market. Net realizable value is defined as the estimated selling price in the ordinary course of business less reasonably predictable costs of completion, disposal and transportation. The Company adopted ASU 2015-11 when it became effective in the first quarter of the 2017 Fiscal Year. The adoption of ASU 2015-11 did not have a material impact on the Company’s consolidated financial statements.

In March 2016, the FASB issued ASU 2016-09, “Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting” (“ASU 2016-09”), which simplifies several aspects of the accounting for employee share-based payment transactions for both public and nonpublic entities, including the accounting for income taxes, forfeitures and statutory tax withholding requirements, as well as classification in the statement of cash flows. The Company adopted ASU 2016-09 when it became effective in the first quarter of the 2017 Fiscal Year on a prospective basis and as such, the Company’s prior year presentation has not changed. The primary impact of the adoption was the recognition of excess tax benefits as a reduction of Income tax expense on the Company’s Consolidated Statements of Operations. As a result, excess tax benefits of $6.8 million were recognized as a reduction of Income tax expense for the year ended December 31, 2017. Historically, these amounts were recorded as Additional paid-in capital in Stockholders’ equity on the Company’s Consolidated Balance Sheets. The Company also elected to adopt the cash flow presentation of the excess tax benefits prospectively commencing in the first quarter of 2017. The Company now presents excess tax benefits or tax deficiencies within operating cash flows versus financing activities on the Consolidated Statements of Cash Flows. Another impact of the adoption is that the calculation of the effect of dilutive securities now excludes any derived excess tax benefits or deficiencies from assumed future proceeds, resulting in an increase in diluted weighted average shares outstanding. Additionally, the Company elected to account for forfeitures of share-based payments as they occur and there was no material financial impact as a result. None of the other provisions in ASU 2016-09 had a material impact on the Company’s consolidated financial statements.

In January 2017, the FASB issued ASU 2017-04, “Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment” (“ASU 2017-04”), which eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge (also known as Step 2 under the current guidance). Rather, the measurement of a goodwill impairment charge will be based on the excess of a reporting unit’s carrying value over its fair value (Step 1 under the current guidance). ASU 2017-04 will be effective for annual and interim goodwill impairment tests performed in periods beginning after December 15, 2019 and should be applied prospectively. Early adoption is permitted for annual and interim goodwill impairment tests beginning after January 1, 2017. The Company adopted ASU 2017-04 in July 2017 with its annual goodwill impairment test. The adoption of ASU 2017-04 did not have a material impact on the Company’s consolidated financial statements and related disclosures.

In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities” (“ASU 2017-12”), which seeks to improve the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements. Additionally, ASU 2017-12 makes certain targeted improvements to simplify the application of the hedge accounting guidance in current GAAP based on the feedback received from preparers, auditors, users, and other stakeholders. ASU 2017-12 adds new disclosure requirements, amends existing ones and removes the requirement for entities to disclose amounts of hedge ineffectiveness. In addition, an entity must now provide tabular disclosures about: both (i) the total amounts reported in the statement of financial performance for each income and expense line item that is affected by fair value or cash flow hedging and (ii) the effects of hedging on those line items; and the carrying amounts and cumulative basis adjustments of items designated and qualifying as hedged items in fair value hedges. Early adoption is permitted in any interim period after issuance of ASU 2017-12. The Company adopted ASU 2017-12 in the third quarter of the 2017 Fiscal Year. The adoption of ASU 2017-12 did not have a material impact on the Company’s consolidated financial statements.

Accounting Pronouncements Issued But Not Yet Adopted

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”), which amends existing revenue recognition standards and establishes a new Accounting Standards Codification (“ASC”) Topic 606. The core principle of this amendment is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for these goods or services. The Company has concluded that it will have substantially similar performance obligations under the amended guidance as compared with deliverables and units of account currently being recognized. Additionally, the Company has made policy elections within the amended standard that are consistent with its current accounting. The Company has evaluated the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures and controls. Based on its assessment, the Company has determined that the adoption of ASU 2014-09 will result in additional revenue recognition disclosures, and will have an immaterial impact on the timing of revenue recognition related to its incentive programs. The Company also evaluated other considerations within the guidance and concluded that there are no additional changes required with adopting ASU 2014-09. The Company will adopt ASU 2014-09 in the first quarter of 2018 using the modified retrospective transition method.

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” (“ASU 2016-02”), which amends the guidance for recognition, measurement, presentation and disclosures of lease arrangements and establishes a new ASC Topic 842. The amended standard will require recognition on the balance sheet for all leases with terms longer than 12 months as a lease liability and as a right-of-use asset. The lease liability is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis, and the right-of-use asset is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. The new standard requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. ASU 2016-02 is effective for the Company commencing in the first quarter of fiscal year 2019. The Company is currently evaluating the amended guidance and the impact on its consolidated financial statements and related disclosures.

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326) - Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”), which changes the way companies evaluate credit losses for most financial assets and certain other instruments. For trade and other receivables, held-to-maturity debt securities, loans and other instruments, entities will be required to use a new forward-looking “expected loss” model to evaluate impairment, potentially resulting in earlier recognition of allowances for losses. The new standard also requires enhanced disclosures, including the requirement to disclose the information used to track credit quality by year of origination for most financing receivables. ASU 2016-13 will be effective for the Company commencing in the first quarter of fiscal year 2020. The guidance must be applied using a cumulative-effect transition method. The Company is currently evaluating the amended guidance and the impact on its consolidated financial statements and related disclosures.

In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”), to provide clarification on cash flow classification related to eight specific issues including debt prepayment or debt extinguishment costs and contingent consideration payments made after a business combination. The guidance in ASU 2016-15 should be applied using a retrospective transition method to each period presented. ASU 2016-15 becomes effective for the Company in the first quarter of fiscal year 2018. The Company is currently evaluating the amended guidance and the impact on its consolidated financial statements and related disclosures.

In October 2016, the FASB issued ASU 2016-16, “Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory”(“ASU 2016-16”), which amends existing guidance to require entities to recognize income tax consequences of an intra-entity transfer of an asset, other than inventory, when the transfer occurs. ASU 2016-16 will be effective for the Company commencing in the first quarter of fiscal year 2018 using a modified retrospective method. The Company is currently evaluating the impact of this amended guidance; however, the provisions of ASU 2016-16 are not expected to have a significant impact on the Company’s consolidated financial statements and related disclosures.

In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash” (“ASU 2016-18”), which requires restricted cash and restricted cash equivalents to be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. Transfers between cash and cash equivalents and restricted cash or restricted cash equivalents are not reported as cash flow activities in the statement of cash flows. ASU 2016-18 will be effective for the Company in the first quarter of fiscal year 2018, using a retrospective transition method. The Company is currently evaluating the amended guidance and the impact on its consolidated financial statements and related disclosures.

In January 2017, the FASB issued ASU 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business” (“ASU 2017-01”), to clarify the definition of a business to assist entities with evaluating whether transactions should be accounted for as acquisitions of assets or businesses. ASU 2017-01 provides a screen to determine when an integrated set of assets and activities (collectively a “set”) is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. If the screen is not met, ASU 2017-01 requires that to be considered a business, a set must include an input and a substantive process that together significantly contribute to the ability to create output. ASU 2017-01 will be effective for the Company in the first quarter of fiscal year 2018, and should be applied prospectively. The Company is currently evaluating the amended guidance; however, the provisions of ASU 2017-01 are not expected to have a material impact on the Company's consolidated financial statements and related disclosures.

In May 2017, the FASB issued ASU 2017-09, “Compensation-Stock Compensation (Topic 718) - Scope of Modification” (“ASU 2017-09”), which provides clarity and reduces both diversity in practice and cost and complexity when applying the guidance in Topic 718 when there are changes to the terms or conditions of a share-based payment award. The amendments in ASU 2017-09 provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. ASU 2017-09 will be effective for the Company in the first quarter of fiscal year 2018 on a prospective basis. The Company is currently evaluating the amended guidance and the impact on its consolidated financial statements and related disclosures.
