This annual report on Form 10-K (this “report”) is a combined annual report being filed separately by two registrants: Summit Materials, Inc. and Summit Materials, LLC. Each registrant hereto is filing on its own behalf all of the information contained in this report that relates to such registrant. Each registrant hereto is not filing any information that does not relate to such registrant, and therefore makes no representation as to any such information. We believe that combining the annual reports on Form 10-K of Summit Materials, Inc. and Summit Materials, LLC into this single report eliminates duplicative and potentially confusing disclosure and provides a more streamlined presentation since a substantial amount of the disclosure applies to both registrants.
Unless stated otherwise or the context requires otherwise, references to “Summit Inc.” mean Summit Materials, Inc., a Delaware corporation, and references to “Summit LLC” mean Summit Materials, LLC, a Delaware limited liability company. The references to Summit Inc. and Summit LLC are used in cases where it is important to distinguish between them. We use the terms “we,” “our,” “Summit Materials” or “the Company” to refer to Summit Inc. and Summit LLC together with their respective subsidiaries, unless otherwise noted or the context otherwise requires.
Summit Inc. was formed on September 23, 2014 to be a holding company. As of January 2, 2021, its sole material asset was a 97.5% economic interest in Summit Materials Holdings L.P. (“Summit Holdings”). Summit Inc. has 100% of the voting rights of Summit Holdings, which is the indirect parent of Summit LLC. Summit LLC is a co-issuer of our 5 1/8% senior notes due 2025 (“2025 Notes”), our 6 1/2% senior notes due 2027 (“2027 Notes”) and our 5 1/4% senior notes due 2029 (“2029 Notes” and collectively with the 2025 Notes and 2027 Notes, the “Senior Notes”). Summit Inc.’s only revenue for the year ended January 2, 2021 is that generated by Summit LLC and its consolidated subsidiaries. Summit Inc. controls all of the business and affairs of Summit Holdings and, in turn, Summit LLC.

We are one of the fastest growing construction materials companies in the United States, with a 63% increase in revenue between the year ended January 2, 2016 (the year of our initial public offering) and the year ended January 2, 2021. Within our markets, we offer customers a single‑source provider for construction materials and related downstream products through our vertical integration. Our materials include aggregates, which we supply across the United States, and in British Columbia, Canada, and cement, which we supply to surrounding states along the Mississippi River from Minnesota to Louisiana. In addition to supplying aggregates to customers, we use a portion of our materials internally to produce ready‑mix concrete and asphalt paving mix, which may be sold externally or used in our paving and related services businesses. Our vertical integration creates opportunities to increase aggregates volumes, optimize margin at each stage of production and provide customers with efficiency gains, convenience and reliability, which we believe gives us a competitive advantage.
Since our inception in 2009, we have become a major participant in the U.S. construction materials industry. We believe that, by volume, we are a top 10 aggregates supplier, a top 15 cement producer and a major producer of ready‑mix concrete and asphalt paving mix. Our proven and probable aggregates reserves were 4.1 billion tons as of January 2, 2021. In the year ended January 2, 2021 we sold 59.1 million tons of aggregates, 2.3 million tons of cement, 5.7 million cubic yards of ready-mix concrete and 5.8 million tons of asphalt paving mix across our more than 400 sites and plants.
The rapid growth we have achieved over the years has been due in large part to our acquisitions, which we funded through equity issuances, debt financings and cash from operations. Over the past decade, the U.S. economy witnessed a cyclical decline followed by a gradual recovery in the private construction market and modest growth in public infrastructure spending. The U.S. private construction market has grown in recent years both nationally and in our markets. During 2020, although the overall U.S. economy experienced a decline related to the COVID-19 pandemic, we continued to see positive indicators for the construction market, including positive trends in housing starts and highway construction letting. We believe we are well positioned to capitalize on growth in the construction market to continue to expand our business.

Our revenue in 2020 was $2.3 billion with net income of $141.2 million. As of January 2, 2021, our total indebtedness outstanding was approximately $1.9 billion.
We anticipate continued growth in our primary end markets, public infrastructure and the private construction market. Public infrastructure, which includes spending by federal, state and local governments for roads, highways, bridges, airports and other public infrastructure projects, has been a relatively stable portion of government budgets providing consistent demand to our industry and is projected by the Portland Cement Association (“PCA”) to grow approximately 8% in the U.S. from 2021 to 2025. We believe states will continue to institute state and local level funding initiatives dedicated towards increased infrastructure spending. We believe that growth in infrastructure spending will not be consistent across the United States, but will vary across different geographies. Economic conditions in our markets do vary by state, and public infrastructure funding has been impacted by COVID -19, particularly in Kentucky and Vancouver, British Columbia. The public infrastructure market represented 39% of our revenue in 2020.
The private construction market includes residential and nonresidential new construction and the repair and remodel market. According to the PCA, the number of total housing starts in the United States, a leading indicator for our residential business, is expected to grow 8% from 2021 to 2025. In addition, the PCA projects that spending in private nonresidential construction will grow 3% over the same period. Growth in private construction spending is influenced by changes in population, employment and general economic activity, among other factors which vary by geography across the United States. Residential activity in our key markets remains strong, particularly in the Houston and Salt Lake City areas, two of the largest metro areas where we operate. We believe residential activity in our key markets will continue to be a driver for volumes in future periods. The private construction market represented 61% of our revenue in 2020.
In addition to anticipated demand growth in our end markets, we expect continued improvement in pricing, especially in our materials businesses. The United States Geological Survey ("USGS") reports that aggregates pricing has increased in 70 of the last 75 years. Accordingly, we believe that this trend will continue in the future. The PCA estimates that cement consumption will increase approximately 10% in the U.S. from 2021 to 2025, reflecting rising demand in the major end markets. We believe that the increased demand will drive higher cement pricing as production capacity in the United States tightens.

Historically, we have supplemented organic growth with acquisitions by strategically targeting attractive, new markets and expanding in existing markets. We consider population trends, employment rates, competitive landscape, private and public construction outlook, public funding and various other factors prior to entering a new market. In addition to considering macroeconomic data, we seek to establish, and believe that we have, a top three position in our local markets, which we believe supports improving profit margins and sustainable organic growth. This positioning provides local economies of scale and synergies, which benefits our profitability. In addition, we also focus on developing greenfield and brownfield sites in our existing markets.
We believe that significant opportunities remain for growth through acquisitions. We estimate that approximately 65% of the U.S. construction materials market is privately owned. Our management team maintains contact with hundreds of private companies. These long‑standing relationships, cultivated over decades, have been the primary source for our past acquisitions and, we believe, will continue to be an important source for future acquisitions. We believe we offer a compelling value proposition for private company sellers, including secure ongoing stewardship of their legacy businesses.

Our Business Segments
We operate in 21 U.S. states and in British Columbia, Canada and have assets in 23 U.S. states and in British Columbia, Canada through our platforms that make up our operating segments: West; East; and Cement. The 10 platform businesses in the West and East segments have their own management teams. The platform management teams are responsible for overseeing the operating platforms, implementing best practices, developing growth opportunities and integrating acquired businesses. We seek to enhance value through increased scale, efficiencies and cost savings within local markets.
West Segment:  Our West segment includes operations in Texas, Utah, Colorado, Idaho, Wyoming, Oklahoma, Nevada and British Columbia, Canada. We supply aggregates, ready‑mix concrete, asphalt paving mix and paving and related services in the West segment. As of January 2, 2021, the West segment controlled approximately 1.3 billion tons of proven and probable aggregates reserves and $602.6 million of net property, plant and equipment and inventories (“hard assets”). During the year ended January 2, 2021, approximately 54% of our revenue was generated in the West segment.

East Segment:  Our East segment serves markets extending across the Midwestern and Eastern United States, most notably in Kansas, Missouri, Virginia, Kentucky, North Carolina, South Carolina, Georgia, Arkansas and Nebraska where we supply aggregates, ready‑mix concrete, asphalt paving mix and paving and related services. As of January 2, 2021, the East segment controlled approximately 2.3 billion tons of proven and probable aggregates reserves and $745.5 million of hard assets. During the year ended January 2, 2021, approximately 34% of our revenue was generated in the East segment.

Cement Segment:  Our Cement segment consists of our Hannibal, Missouri and Davenport, Iowa cement plants and nine distribution terminals along the Mississippi River from Minnesota to Louisiana. Our highly efficient plants are complemented by our integrated distribution system that spans the Mississippi River. We process solid and liquid waste into fuel for the plants, which can reduce the plants’ fuel costs by up to 50%. The Hannibal, Missouri plant is one of very few cement facilities in the United States that can process both hazardous and non-hazardous solid and liquid waste into fuel. As of January 2, 2021, the Cement segment controlled approximately 0.5 billion tons of proven and probable aggregates reserves, which serve its cement business, and $584.7 million of hard assets. During the year ended January 2, 2021, approximately 12% of our revenue was generated in the Cement segment.

Our End Markets
Public Infrastructure.  Public infrastructure construction includes spending by federal, state and local governments for highways, bridges, airports, schools, public buildings and other public infrastructure projects. Public infrastructure spending has historically been more stable than private sector construction. We believe that public infrastructure spending is less sensitive to interest rate changes and economic cycles and often is supported by multi-year federal and state legislation and programs. A significant portion of our revenue is derived from public infrastructure projects. As a result, the supply of federal and state funding for public infrastructure highway construction significantly affects our public infrastructure end-use business.
In the past, public infrastructure sector funding was underpinned by a series of six‑year federal highway authorization bills. Federal funds are allocated to the states, which are required to match a portion of the federal funds they receive. Federal highway spending uses funds predominantly from the Federal Highway Trust Fund, which derives its revenue from taxes on diesel fuel, gasoline and other user fees. The dependability of federal funding allows the state departments of transportation to plan for their long-term highway construction and maintenance needs. The Fixing America’s Surface Transportation (“FAST”) Act was signed into law on December 4, 2015 and authorized $305 billion of funding from 2016 through 2020. Through a continuing resolution signed by the President in October 2020, funding for the existing federal transportation funding program now extends through September 2021. It provides funding for surface transportation infrastructure, including roads, bridges, transit systems, and the rail transportation network.
Residential Construction.  Residential construction includes single family homes and multi‑family units such as apartments and condominiums. Demand for residential construction is influenced primarily by employment prospects, new household formation and mortgage interest rates. In recent years, residential construction demand has been growing, although the rate of growth has varied across the U.S. As a result of the COVID-19 pandemic, migration trends towards rural and exurban U.S. markets has begun, including a notable influx in our Texas and Utah markets.
Nonresidential Construction.  Nonresidential construction encompasses all privately financed construction other than residential structures. Demand for nonresidential construction is driven primarily by population and economic growth, and activity tends to following residential activity by 12-24 months. Population growth spurs demand for stores, shopping centers and restaurants. Economic growth creates demand for projects such as hotels, office buildings, warehouses and factories,

although growth rates vary across the U.S. The supply of nonresidential construction projects is also affected by interest rates and the availability of credit to finance these projects.
Our Competitive Strengths
Leading market positions.  We believe each of our operating companies has a top three market share position in its local market area achieved through their respective, extensive operating histories, averaging over 30 years. We believe we are a top 10 supplier of aggregates, a top 15 producer of cement and a major producer of ready‑mix concrete and asphalt paving mix in the United States by volume. We focus on acquiring aggregate-based companies that have leading local market positions, which we seek to enhance by building scale through additional bolt-on acquisitions. The construction materials industry is highly local in nature due to transportation costs from the high weight‑to‑value ratio of the products. Given this dynamic, we believe achieving local market scale provides a competitive advantage that drives growth and profitability for our business. We believe that our ability to prudently acquire, rapidly integrate and improve multiple businesses has enabled, and will continue to enable, us to become market leaders.
Operations positioned to benefit from attractive industry fundamentals.  We believe the construction materials industry has attractive fundamentals, characterized by high barriers to entry and a stable competitive environment in the majority of markets. Barriers to entry are created by scarcity of raw material resources, limited efficient distribution range, asset intensity of equipment, land required for quarry operations and a time‑consuming and complex regulatory and permitting process. According to a January 2020 U.S. Geological Survey, aggregates pricing in the United States had increased in 70 of the previous 75 years, with growth accelerating since 2002 as continuing resource scarcity in the industry has led companies to focus increasingly on improved pricing strategies.
One contributing factor that supports pricing growth through the economic cycles is that aggregates and asphalt paving mix have significant exposure to public road construction, which has demonstrated growth over the past 30 years, even during times of broader economic weakness. The majority of public road construction spending is funded at the state level through the states’ respective departments of transportation. Texas, Utah, Kansas and Missouri, four of the states in which we have had our highest revenues, have funds with certain constitutional protections for revenue sources dedicated for transportation projects. These dedicated, earmarked funding sources limit the negative effect state deficits may have on public spending. As a result, we believe our business’ profitability is significantly more stable than most other building product subsectors.
Vertically‑integrated business model.  We generate revenue across a spectrum of related products and services. Approximately 21% of the aggregates used in our products and services are internally supplied. Our vertically‑integrated business model enables us to operate as a single source provider of materials and paving and related services, creating cost, convenience and reliability advantages for our customers, while at the same time creating significant cross‑marketing opportunities among our interrelated businesses. We believe this creates opportunities to increase aggregates volumes, optimize margin at each stage of production, foster more stable demand for aggregates through a captive demand outlet, create a competitive advantage through the efficiency gains, convenience and reliability provided to customers and enhance our acquisition strategy by providing a greater population of target companies.
Attractive diversity, scale and product portfolio.  We operate in dozens of metropolitan statistical areas across 23 U.S. states and in British Columbia, Canada. Between the year ended January 2, 2016 (the year of our initial public offering) and the year ended January 2, 2021, we grew our revenue by 63% and brought substantial additional scale and geographic diversity to our operations. In the year ended January 2, 2021, 59% of our operating income increase came from the West segment, 23% from East segment and 18% from the Cement segment, excluding corporate charges. As of January 2, 2021, we had approximately 4.1 billion tons of proven and probable aggregates reserves serving our aggregates and cement business. We estimate that the useful life of our proven and probable reserves serving our aggregates and cement businesses are approximately 74 years and 273 years, respectively, based on the average production rates in 2020 and 2019.
Our dry process cement plants in Hannibal, Missouri and Davenport, Iowa were commissioned in 2008 and 1981, respectively. These low-cost cement plants have efficient manufacturing capabilities and are strategically located on the Mississippi River and complemented by an extensive network of river and rail fed distribution terminals. Our terminal network can accept imported cement to supplement our internal production capacity as demand and market conditions dictate. Due to the location of our Hannibal and Davenport plants on the Mississippi River, in 2020, approximately 66% of cement distributed to our terminals was shipped by barge, which is generally more cost-effective than truck transport.
Proven ability to incorporate new acquisitions and grow businesses.  Since our inception, we have acquired dozens of businesses, successfully integrating them into three segments through the implementation of operational improvements, industry‑proven information technology systems, a comprehensive safety program and best in class management programs. A

typical acquisition and subsequent integration generally involves implementing common safety and financial back office systems, driving best practices in pricing and productivity. In addition, we seek to leverage scale while maintaining local branding and management decision-making and providing management support, strategic direction and financial capital for investment. These acquisitions have helped us achieve significant revenue growth, from $0.4 billion in 2010 to $2.3 billion in 2020.
Experienced and proven leadership driving organic growth and acquisition strategy. Our management team, including corporate and segment managers, corporate development, finance executives and other heavy side industry operators, has extensive experience in the industry. Our management team has successfully enhanced the operations of acquired companies, focusing on scale advantages, cost efficiencies and price optimization to improve profitability and cash flow.

Our Business Strategy
Utilize vertically‑integrated and strategically located operations for growth.  We believe that our vertical integration of construction materials, products and services is a significant competitive advantage that we will utilize to grow share in our existing markets and enter into new markets. A significant portion of materials used to produce our products and provide services to our customers is internally supplied, which enables us to operate as a single source provider of materials, products and paving and related services. This creates cost, convenience and reliability advantages for our customers and enables us to capture additional value throughout the supply chain, while at the same time creating significant cross‑marketing opportunities among our interrelated businesses.
Enhance margins and free cash flow generation through implementation of operational improvements.  Our management team includes individuals with decades of experience in our industry and proven success in integrating acquired businesses and organically growing operations. We have enhanced margins through proven profit optimization plans, managed working capital and achieved scale‑driven purchasing synergies and fixed overhead control and reduction. Our platform management teams, supported by our operations, development, risk management, information technology and finance teams, drive the implementation of detailed and thorough profit optimization plans for each acquisition post close. These integration and improvement plans typically include, among other things, implementation of a common pricing strategy, safety and financial systems, systematic commercial strategies, operational benefits, efficiency improvement plans and business-wide cost reduction techniques.
Expand local positions in the most attractive markets through targeted capital investments and bolt‑on acquisitions.  We seek to expand our business through organic growth and bolt‑on acquisitions in each of our local markets. In addition to our greenfield and brownfield project initiatives, our acquisition strategy involves acquiring platforms that serve as the foundation for continued incremental and complementary growth via locally situated bolt‑on acquisitions to these platforms. We believe that increased local market scale drives profitable growth through efficiencies. Our existing platform of operations is expected to enable us to continue our growth as we expand in our existing markets. In pursuing our growth strategy, we may also pursue larger acquisition transactions that may require us to raise additional equity capital and or debt from time to time. Consistent with this strategy, we regularly evaluate potential acquisition opportunities, including ones that would be significant to us.
Drive profitable growth through strategic acquisitions.  Based on aggregates sales, by volume, we believe that we are currently one of the ten largest producers in the United States. Our growth has been a result of the successful execution of our acquisition strategy and implementation of best practices to drive organic growth. We believe that the relative fragmentation of our industry creates an environment in which we can continue to acquire companies at attractive valuations and increase scale and diversity over time. We believe we have opportunity for further growth through strategic acquisitions in markets adjacent to our existing markets within the states where we currently operate, as well as into additional states as market and competitive conditions permit.
Capitalize on growth in the U.S. economy and construction markets.  Given the nation’s aging infrastructure and considering longstanding historical spending trends, we expect U.S. infrastructure investment to grow over time. We believe we are well positioned to capitalize on any such increase in investment.  The PCA forecasts total housing starts to accelerate to 1.48 million in the United States by 2025. The American Institute of Architects’ Consensus Construction Forecast projects nonresidential construction to shrink 4.8% in 2021. We believe nonresidential activity tends to follow residential activity after about 12 to 24 months. However, the COVID-19 pandemic may impact these trends in ways we cannot foresee. We believe that exposure to the public infrastructure, residential and nonresidential end markets across our markets will benefit us if the U.S. economy improves.

Our Industry
The U.S. construction materials industry is composed of four primary sectors: aggregates; cement; ready‑mix concrete; and asphalt paving mix. Each of these materials is widely used in most forms of construction activity. Participants in these sectors typically range from small, privately‑held companies focused on a single material, product or market to publicly traded multinational corporations that offer a wide array of construction materials and services. Competition is constrained in part by the distance materials can be transported efficiently, resulting in predominantly local or regional operations. Due to the lack of product differentiation, competition for all of our products is predominantly based on price and, to a lesser extent, quality of products and service. As a result, the prices we charge our customers are not likely to be materially different from the prices charged by other producers in the same markets. Accordingly, our profitability is generally dependent on the level of demand for our products and materials and our ability to control operating costs.
Transportation infrastructure projects, driven by both federal and state funding programs, represent a significant share of the U.S. construction materials market. Federal funds are allocated to the states, which are required to match a portion of the federal funds they receive. Federal highway spending uses funds predominantly from the Federal Highway Trust Fund, which derives its revenue from taxes on diesel fuel, gasoline and other user fees. The dependability of federal funding allows the state departments of transportation to plan for their long-term highway construction and maintenance needs. Funding for the existing federal transportation funding program extends through September 2021. With the nation’s infrastructure aging, there is increased demand by states and municipalities for long-term federal funding to support the construction of new roads, highways and bridges in addition to the maintenance of existing infrastructure.
In addition to federal funding, state, county and local agencies provide highway construction and maintenance funding. Our four largest states by revenue, Texas, Utah, Kansas and Missouri, represented approximately 25%, 14%, 13% and 9%, respectively, of our total revenue in 2020.
Our Industry and Operations
Demand for our materials and products is observed to have low elasticity in relation to prices. We believe this is partially explained by the absence of competitive replacement products. We do not believe that increases in our prices of materials or products are likely to affect the decision to undertake a construction project since these costs usually represent a small portion of total construction costs.
We operate our construction materials, products and paving and related services businesses through local management teams, which work closely with our end customers to deliver the materials, products and services that meet each customer’s specific needs for a project. We believe that this strong local presence gives us a competitive advantage by allowing us to obtain a unique understanding for the evolving needs of our customers.
We have operations in 23 U.S. states and in British Columbia, Canada. Our business in each region is vertically‑integrated. We supply aggregates internally for the production of cement, ready‑mix concrete and asphalt paving mix and a significant portion of our asphalt paving mix is used internally by our paving and related services businesses. In the year ended January 2, 2021, approximately 79% of our aggregates production was sold directly to outside customers with the remaining amount being further processed by us and sold as a downstream product. In addition, we operate a municipal waste landfill in our East segment, and have construction and demolition debris landfills and liquid asphalt terminal operations in our West and East segments.

Approximately 69% of our asphalt paving mix was installed by our paving and related services businesses in the year ended January 2, 2021. We charge a market price and competitive margin at each stage of the production process in order to optimize profitability across our operations. Our production value chain is illustrated as follows:

Table of Contents

Aggregates are key material components used in the production of cement, ready‑mix concrete and asphalt paving mixes for the public infrastructure, residential and nonresidential end markets and are also widely used for various applications and products, such as road and building foundations, railroad ballast, erosion control, filtration, roofing granules and in solutions for snow and ice control. Generally extracted from the earth using surface or underground mining methods, aggregates are produced from natural deposits of various materials such as limestone, sand and gravel, granite and trap rock. Aggregates are produced mainly from blasting hard rock from quarries and then crushing and screening it to various sizes to meet our customers’ needs. The production of aggregates also involves the extraction of sand and gravel, which requires less crushing, but still requires screening for different sizes. Aggregate production utilizes capital intensive heavy equipment which includes the use of loaders, large haul trucks, crushers, screens and other heavy equipment at quarries and sand and gravel pits. Once extracted, processed and/or crushed and graded on-site into crushed stone, concrete and masonry sand, specialized sand, pulverized lime or agricultural lime, they are supplied directly to their end use or incorporated for further processing into construction materials and products, such as cement, ready‑mix concrete and asphalt paving mix. The minerals are processed to meet customer specifications or to meet industry standard sizes. Crushed stone is used primarily in ready‑mix concrete, asphalt paving mix, and the construction of road base for highways.
We believe that the long‑term growth of the market for aggregates is predominantly driven by growth in population, employment and households, which in turn affects demand for transportation infrastructure, residential and nonresidential construction, including stores, shopping centers and restaurants. While short‑term demand for aggregates fluctuates with economic cycles, the declines have historically been followed by strong recovery, with each peak establishing a new historical high.
We mine limestone, gravel, and other natural resources from 132 crushed stone quarries and 116 sand and gravel deposits throughout the United States and in British Columbia, Canada. Our extensive network of quarries, plants and facilities, located throughout the regions in which we operate, enables us to have a nearby operation to meet the needs of customers in each of our markets. As of January 2, 2021, we had approximately 4.1 billion tons of proven and probable reserves of recoverable stone, and sand and gravel of suitable quality for economic extraction. Our estimate is based on drilling and studies by geologists and engineers, recognizing reasonable economic and operating restraints as to maximum depth of extraction and permit or other restrictions. Reported proven and probable reserves include only quantities that are owned or under lease, and for which all required zoning and permitting have been obtained. Of the 4.1 billion tons of proven and probable aggregates reserves, 2.4 billion, or 58%, are located on owned land and 1.7 billion are located on leased land.

According to the September 2020 U.S. Geological Survey, approximately 1.7 billion tons of crushed stone with a value of approximately $18.4 billion was produced in the United States in 2019, which was an increase from the 1.5 billion tons produced in 2018. Sand and gravel production was approximately 1.1 billion tons in 2019 and 2018, valued at approximately $9.0 billion in 2019. The U.S. aggregate industry is highly fragmented relative to other building product markets, with numerous participants operating in localized markets and the top ten players controlling approximately 35% of the national market in 2020. In February 2020, the U.S. Geological Survey reported that a total of 1,430 companies operating 3,440 quarries

Table of Contents
and 176 sales/distribution yards produced or sold crushed stone in 2019 in the United States. This fragmentation is a result of the cost of transporting aggregates, which typically limits producers to a market area within approximately 40 miles of their production facilities.
Transportation costs are a major variable in determining the marketing radius for our products. The cost of transporting aggregate products from the plant to the market often equates to or exceeds the sale price of the product at the plant. As a result of the high transportation costs and the large quantities of bulk material that have to be shipped, finished products are typically marketed locally. High transportation costs are responsible for the wide dispersion of production sites. Where possible, construction material producers maintain operations adjacent to highly populated areas to reduce transportation costs and enhance margins. However, more recently, rising land values combined with local environmental concerns have been forcing production sites to move further away from the end‑use locations.
Each of our aggregates operations is responsible for the sale and marketing of its aggregates products. Approximately 79% of our aggregates production is sold directly to outside customers and the remaining amount is further processed by us and sold as a downstream product. Even though aggregates are a commodity product, we work to optimize pricing depending on the site location, availability of a particular product, customer type, project type and haul cost. We sell aggregates to internal downstream operations at market prices.
A significant portion of annual demand for aggregates is derived from large public infrastructure and highway construction projects. According to the Montana Contractors’ Association, approximately 38,000 tons of aggregate are required to construct a one mile stretch of a typical four‑lane interstate highway. Highways located in markets with significant seasonal temperature variances are particularly vulnerable to freeze‑thaw conditions that exert excessive stress on pavement and lead to more rapid surface degradation. Surface maintenance repairs, as well as general highway construction, occur in the warmer months, resulting in a majority of aggregates production and sales in the period from April through November in most states.
Our competitors in aggregates supply include large vertically‑integrated companies, that have a combined estimated market share of approximately 30%, in addition to various local suppliers.
We believe we have a strong competitive advantage in aggregates through our well located reserves and assets in key markets, high quality reserves and our logistic networks. We further share and implement best practices relating to safety, strategy, sales and marketing, production, and environmental and land management. Our vertical integration and local market knowledge enable us to maintain a strong understanding of the needs of our aggregates customers. In addition, our companies have a reputation for responsible environmental stewardship and land restoration, which assists us in obtaining new permits and new reserves.
Portland cement, an industry term for the common cement in general use around the world, is made from a combination of limestone, shale, clay, silica and iron ore. It is a fundamental building material consumed in several stages throughout the construction cycle of public infrastructure, residential and nonresidential projects. It is a binding agent that, when mixed with sand or aggregates and water, produces either ready‑mix concrete or mortar and is an important component of other essential construction materials. Few construction projects can take place without utilizing cement somewhere in the design, making it a key ingredient used in the construction industry. The majority of all cement shipments are sent to ready‑mix concrete operators. Sales are made on the basis of competitive terms and prices in each market. Nearly two‑thirds of U.S. consumption occurs between May and November, coinciding with end‑market construction activity.
Cement production in the United States is distributed among over 90 production facilities located across a majority of the states and is a capital‑intensive business with variable costs dominated by raw materials and energy required to fuel the kiln. Most U.S. cement producers are owned by large foreign companies operating in multiple international markets. Our largest competitors include large vertically integrated companies. Construction of cement production facilities is highly capital intensive and requires long lead times to complete engineering design, obtain regulatory permits, acquire equipment and construct a plant.
As reported by the PCA, consumption is up from the industry trough of approximately 77.6 million tons in 2010, to approximately 112.6 million tons in 2019, consistent with an increase in U.S. construction activity. Cement sales are still below their peak, but we believe there will be additional growth in the cement industry. U.S. cement consumption has at times outpaced domestic production capacity with the shortfall being supplied with imports, primarily from Canada, Turkey, Greece, Mexico and China. The PCA reports that cement imports are above their trough of approximately 7.2 million tons in 2011 versus approximately 17.8 million tons in 2019.

Table of Contents
We operate a highly‑efficient, low-cost integrated cement manufacturing and distribution network through our cement plants in Hannibal, Missouri, and Davenport, Iowa and our nine terminals along the Mississippi River from Minnesota to Louisiana. The combined potential capacity at our Hannibal and Davenport cement plants is approximately 2.4 million short tons per annum. We also operate on‑site waste fuel processing facilities at the plants, which can reduce plant fuel costs by up to 50%. Our Hannibal plant is one of very few with hazardous waste fuel facilities permitted and operating out of over 90 cement plants in the United States. Competitive factors include price, reliability of deliveries, location, quality of cement and support services. With two cement plants, on‑site raw material supply, a network of cement terminals, and longstanding customer relationships, we believe we are well positioned to serve our customers.
Cement is a product that is costly to transport. Consequently, the radius within which a typical cement plant is competitive with truck transportation is typically limited to 150 miles from any shipping/distribution point. However, access to rail and barge can extend the distribution radius significantly. With both of our plants located on the Mississippi River, we are able to cost effectively distribute cement from both of our plants by truck, rail and barge directly to customers or to our nine storage and distribution terminals along the Mississippi River. Our Hannibal and Davenport plants are located on the Mississippi River and, consequently, in 2020, approximately 66% of cement distributed to our terminals was shipped by barge, which is significantly more cost‑effective than truck transport.
The majority of U.S. cement plants are subject to the Portland Cement – Maximum Achievable Control Technology (“PC‑MACT”). Our Hannibal and Davenport cement plants utilize alternative fuels, hazardous and non‑hazardous at Hannibal and non‑hazardous at Davenport, as well as coal, natural gas and petroleum coke and, as a result, are subject to the Hazardous Waste Combustor – Maximum Achievable Control Technology (“HWC-MACT”) and Commercial/Industrial Solid Waste Incinerators (“CISWI”) standards, respectively, rather than PC‑MACT standards.

Ready‑mix Concrete
Ready‑mix concrete is one of the most versatile and widely used materials in construction today. Its flexible recipe characteristics allow for an end product that can assume almost any color, shape, texture and strength to meet the many requirements of end users that range from bridges, foundations, skyscrapers, pavements, dams, houses, parking garages, water treatment facilities, airports, tunnels, power plants, hospitals and schools. The versatility of ready‑mix concrete gives engineers significant flexibility when designing these projects.
Cement, coarse aggregate, fine aggregate, water and admixtures are the primary ingredients in ready‑mix concrete. Other materials commonly used in the production of ready‑mix concrete include fly‑ash, a waste by‑product from coal burning power plants, silica fume, a waste by‑product generated from the manufacture of silicon and ferro‑silicon metals, and ground granulated blast furnace slag, a by‑product of the iron and steel manufacturing process. These materials are available directly from the producer or via specialist distributors who intermediate between the ready‑mix concrete producers and the users.
Competition among ready‑mix concrete suppliers is generally based on product characteristics, delivery times, customer service and price. Product characteristics such as tensile strength, resistance to pressure, durability, set times, ease of placing, aesthetics, workability under various weather and construction conditions as well as environmental effect are the main criteria that our customers consider for selecting their product. Our quality assurance program produces results in excess of design strengths while optimizing material costs. Additionally, we believe our strategic network of locations and superior customer service gives us a competitive advantage relative to other producers. Our ready‑mix concrete operations compete with CEMEX in Texas and Nevada and CRH plc in Utah and Colorado and various other privately owned competitors in other parts of the West and East segments.
Given the high weight‑to‑value ratio, delivery of ready‑mix concrete is typically limited to a one‑hour haul from a production plant and is further limited by a 90 minute window in which newly‑mixed concrete must be poured to maintain quality and performance. As a result of the transportation constraints, the ready‑mix concrete market is highly localized, with an estimated 5,500 ready‑mix concrete plants in the United States according to the NRMCA. According to the NRMCA, 371.2 million cubic yards of ready‑mix concrete were produced in 2019, which is a 4% increase from the 358.2 million cubic yards produced in 2018 but a 19% decrease from the industry peak of 458.3 million cubic yards in 2005.
We believe our West and East segments are leaders in the supply of ready‑mix concrete in their respective markets. The West segment has ready‑mix concrete operations in the Texas, Utah, Nevada, Idaho and Colorado markets. Our East segment supplies ready‑mix concrete in the Kansas, Missouri, Arkansas, North Carolina, South Carolina, Kentucky and Virginia markets and surrounding areas. We operated 69 ready-mix concrete plants and over 700 concrete delivery trucks in the West segment and 55 ready-mix concrete plants and almost 350 concrete delivery trucks in the East segment as of January 2,

Table of Contents
2021. Our aggregates business serves as the primary source of the raw materials for our concrete production, functioning essentially as a supplier to our ready‑mix concrete operations.

Asphalt Paving Mix
Asphalt paving mix is the most common roadway material used today. It is a versatile and essential building material that has been used to surface 94% of the more than 2.7 million miles of paved roadways in the United States, according to the National Asphalt Pavement Association (“NAPA”).
Typically, asphalt paving mix is placed in three distinct layers to create a flexible pavement structure. These layers consist of a base course, an intermediate or binder course, and a surface or wearing course. These layers vary in thicknesses of three to six inches for base mix, two to four inches for intermediate mix and one to two inches for surface mix.
Asphalt pavement is generally 100% recyclable and reusable and is the most reused and recycled pavement material in the United States. Reclaimed asphalt pavement can be incorporated into new pavement at replacement rates in excess of 30% depending upon the mix and the application of the product. We actively engage in the recycling of previously used asphalt pavement and concrete. This material is crushed and repurposed in the construction cycle. Approximately 89.2 million tons of used asphalt is recycled annually by the industry according to a September 2020 NAPA survey. As of January 2, 2021, we operated 26 and 23 asphalt paving mix plants in the West and East segments, respectively. Approximately 98% of our plants can utilize recycled asphalt pavement.
The use of warm mix asphalt (“WMA”) or “green” asphalt is gaining popularity. The immediate benefit to producing WMA is the reduction in energy consumption required by burning fuels to heat traditional hot mix asphalt (“HMA”) to temperatures in excess of 300°F at the production plant. These high production temperatures are needed to allow the asphalt binder to become viscous enough to completely coat the aggregate in the HMA, have good workability during laying and compaction, and durability during traffic exposure. According to the Federal Highway Administration, WMA can reduce the mixing temperature by 50°F to 70°F, resulting in lower emissions, fumes and odors generated at the plant and the paving site.
Approximately 69% of the asphalt paving mix we produce is installed by our own paving crews. The rest is sold on a per ton basis to road contractors, state departments of transportation and local agencies. Asphalt paving mix is used by our paving crews and by our customers primarily for the construction of roads, driveways and parking lots.
According to NAPA, there were approximately 3,500 asphalt paving mix plants in the United States in 2019 and an estimated 421.9 million tons of asphalt paving mix was produced in 2019 compared to 389.3 million tons produced in 2018. Our asphalt paving mix operations compete with CRH plc and other local suppliers. Based on availability of internal aggregate supply, quality, operating efficiencies, and location advantages, we believe we are well positioned vis‑à‑vis our competitors.
Asphalt paving mix is generally applied at high temperatures. Prolonged exposure to air causes the mix to lose temperature and harden. Therefore, delivery is typically within close proximity to the asphalt paving mix plant. Local market demand, proximity to competition, transportation costs and supply of aggregates and liquid asphalt vary widely from market to market. Most of our asphalt operations use a combination of company‑owned and hired haulers to deliver materials to job sites.
As part of our vertical integration strategy, we provide asphalt paving and related services to both the private and public infrastructure sectors as either a prime or sub‑contractor. These services complement our construction materials and products businesses by providing a reliable downstream outlet, in addition to our external distribution channels.

Our asphalt paving and related services businesses bid on both private construction and public infrastructure projects in their respective local markets. We only provide paving and related services operations as a complement to our aggregates operations, which we believe is a major competitive strength. Factors affecting competitiveness in this business segment include price, estimating abilities, knowledge of local markets and conditions, project management, financial strength, reputation for quality and the availability of machinery and equipment.
Contracts with our customers are primarily fixed price or fixed unit price. Under fixed unit price contracts, we provide materials or services at fixed unit prices (for example, dollars per ton of asphalt placed). While the fixed unit price contract shifts the risk of estimating the quantity of units required for a particular project to the customer, any increase in our unit cost over the bid amount, whether due to inflation, inefficiency, errors in our estimates or other factors, is borne by us unless otherwise provided in the contract. Most of our contracts contain adjustment provisions to account for changes in liquid asphalt prices.

Our business is not dependent on any single customer or a few customers. Therefore, the loss of any single or particular small number of customers would not have a material adverse effect on any individual respective market in which we operate or on us as a whole. No individual customer accounted for more than 10% of our 2020 revenue.
Use and consumption of our products fluctuate due to seasonality. Nearly all of the products used by us, and by our customers, in the private construction or public infrastructure industries are used outdoors. Our highway operations and production and distribution facilities are also located outdoors. Therefore, seasonal changes and other weather‑related conditions, in particular extended rainy and cold weather in the spring and fall and major weather events, such as hurricanes, tornadoes, tropical storms, heavy snows and flooding, can adversely affect our business and operations through a decline in both the use of our products and demand for our services. In addition, construction materials production and shipment levels follow activity in the construction industry, which typically occurs in the spring, summer and fall. Warmer and drier weather during the second and third quarters of our fiscal year typically result in higher activity and revenue levels during those quarters. The first quarter of our fiscal year typically has lower levels of activity due to weather conditions.
Our products are generally delivered upon receipt of orders or requests from customers, or shortly thereafter. Accordingly, the backlog associated with product sales is converted into revenue within a relatively short period of time. Inventory for products is generally maintained in sufficient quantities to meet rapid delivery requirements of customers. Therefore, a period over period increase or decrease of backlog does not necessarily result in an improvement or a deterioration of our business. Our backlog includes only those products and projects for which we have obtained a purchase order or a signed contract with the customer and does not include products purchased and sold or services awarded and provided within the period.
Subject to applicable contract terms, substantially all contracts in our backlog may be canceled or modified by our customers. Historically, we have not been materially adversely affected by significant contract cancellations or modifications.
Intellectual Property
We do not own or have a license or other rights under any patents that are material to our business.

Corporate Information
Summit Materials, Inc. and Summit Materials, LLC were formed under the laws of the State of Delaware on September 23, 2014 and September 24, 2008, respectively. Our principal executive office is located at 1550 Wynkoop Street, 3rd Floor, Denver, Colorado 80202. Through its predecessor, Summit Inc. commenced operations in 2009 when Summit Holdings was formed. Our telephone number is (303) 893-0012.
Human Capital Resources
As of January 2, 2021, we employed approximately 6,000 employees, of which approximately 5,700 were employed in the United States with the remainder being employed in Canada. Approximately 80% of our employees are hourly workers, with the remainder being salaried. Approximately 7% of our employees are union members, substantially all in our cement division and at our Canadian operations, with whom we believe we enjoy a satisfactory working relationship. Our collective bargaining agreements for employees who are union members generally expire between 2022 and 2026. Because of the seasonal nature of our industry, many of our hourly and certain of our salaried employees are subject to seasonal layoffs. The scope of layoffs varies greatly from season to season as they are predominantly a function of the type of projects in process and the weather during the late fall through early spring.

Health and Safety: We maintain a safety culture grounded on the premise of striving to eliminate workplace incidents, risks and hazards. We have created and implemented processes to help eliminate safety events by reducing their frequency and severity. We also review and monitor our performance closely. Our goal is to reduce Occupational Safety and Health Administration ("OSHA") recordable incidents each year. During fiscal 2020, our recordable incident rate declined 6% compared to fiscal 2019.

As a result of the COVID-19 pandemic, we have implemented safety protocols to protect our employees, contractors and customers. These protocols include complying with social distancing and other health and safety standards as required by federal, state and local government agencies, taking into consideration guidelines of the Centers for Disease Control and Prevention and other public health authorities. We continue to provide personal protective equipment and additional cleaning supplies. Many of our administrative and operational functions during this time have required modification, including some of our workforce working remotely. Our experienced employees adapted to the changes in our work environment and continued to successfully manage our business successfully during this challenging time.

Inclusion and Diversity: We embrace the diversity of our team members, customers, stakeholders and consumers, including their unique backgrounds, experiences, thoughts and talents. Everyone is valued and appreciated for their distinct contributions to the growth and sustainability of our business. We strive to cultivate a culture and vision that supports and enhances our ability to recruit, develop and retain diverse talent at every level. We have a goal to build a highly engaged team by increasing retention year over year.

Talent Development: We prioritize and invest in creating opportunities to help employees grow and build their careers, through various training and development programs. These include on-the-job learning formats as well as executive talent and succession planning paired with an individualized development approach.

Compensation and Benefits: We provide compensation and benefit programs to help meet the needs of our employees. In addition to base compensation, we offer incentive plans for both safety and operational results, stock awards, a 401(k) plan, healthcare and insurance benefits, health savings and flexible spending accounts, paid time off, family leave programs, employee assistance programs, among others. Our 401(k) plan covers all U.S. employees, and provides for matching contributions to the plan, including 100% of pre‑tax employee contributions, up to 4% of eligible compensation. Employer contributions vest immediately.
Legal Proceedings
We are party to certain legal actions arising from the ordinary course of business activities. While the ultimate results of claims and litigation cannot be predicted with certainty, management expects that the ultimate resolution of all current pending or threatened claims and litigation will not have a material effect on our consolidated financial condition, results of operations or liquidity.

In March 2018, we were notified of an investigation by the Canadian Competition Bureau (the “CCB”) into pricing practices by certain asphalt paving contractors in British Columbia, including Winvan Paving, Ltd. (“Winvan”). We believe the investigation is focused on time periods prior to our April 2017 acquisition of Winvan and we are cooperating with the CCB. Although we currently do not believe this matter will have a material adverse effect on our business, financial condition or results of operations, we are not able to predict the ultimate outcome or cost of the investigation at this time.
Environmental and Government Regulation
We are subject to federal, state, provincial and local laws and regulations relating to the environment and to health and safety, including noise, discharges to air and water, waste management including the management of hazardous waste used as a fuel substitute in our cement plants, remediation of contaminated sites, mine reclamation, operation and closure of landfills and dust control and zoning, land use and permitting. Our failure to comply with such laws and regulations can result in sanctions such as fines or the cessation of part or all of our operations. From time to time, we may also be required to conduct investigation or remediation activities. There also can be no assurance that our compliance costs or liabilities associated with such laws and regulations or activities will not be significant.
In addition, our operations require numerous governmental approvals and permits. Environmental operating permits are subject to modification, renewal and revocation and can require us to make capital, maintenance and operational expenditures to comply with the applicable requirements. Stricter laws and regulations, or more stringent interpretations of existing laws or regulations, may impose new liabilities on us, reduce operating hours, require additional investment by us in pollution control equipment or impede our opening new, expanding or maintaining existing plants or facilities. We regularly monitor and review our operations, procedures and policies for compliance with environmental laws and regulations, changes in interpretations of existing laws and enforcement policies, new laws that are adopted, and new requirements that we anticipate will be adopted that could affect our operations.
Multiple permits are required for our operations, including those required to operate our cement plants. Applicable permits may include conditional use permits to allow us to operate in certain areas absent zoning approval and operational permits governing, among other matters, air and water emissions, dust, particulate matter and storm water management and

control. In addition, we are often required to obtain bonding for future reclamation costs, most commonly specific to restorative grading and seeding of disturbed surface areas.

Like others in our industry, we expend substantial amounts to comply with applicable environmental laws and regulations and permit limitations, which include amounts for pollution control equipment required to monitor and regulate emissions into the environment. The Hannibal and Davenport cement plants are subject to HWC-MACT and CISWI standards, respectively, for which we do not expect any material incremental costs to maintain compliance. Since many environmental requirements are likely to be affected by future legislation or rule making by government agencies, and are therefore not quantifiable, it is not possible to accurately predict the aggregate future costs of compliance and their effect on our future financial condition, results of operations and liquidity.
At most of our quarries, we incur reclamation obligations as part of our mining activities. Reclamation methods and requirements can vary depending on the individual site and state regulations. Generally, we are required to grade the mined properties to a certain slope and seed the property to prevent erosion. We record a mining reclamation liability in our consolidated financial statements to reflect the estimated fair value of the cost to reclaim each property including active and closed sites.
Our operations in Kansas include one municipal waste landfill and four construction and demolition debris landfills, one of which has been closed and in Colorado, we have a construction and demolition debris landfill. In Vancouver, British Columbia, we operate a landfill site that accepts environmentally clean soil deposits. Among other environmental, health and safety requirements, we are subject to obligations to appropriately close those landfills at the end of their useful lives and provide for appropriate post‑closure care. Asset retirement obligations relating to these landfills are recorded in our consolidated financial statements.
Health and Safety
Our facilities and operations are subject to a variety of worker health and safety requirements, particularly those administered by the federal Occupational Safety and Health Administration (“OSHA”) and Mine Safety and Health Administration (“MSHA”). Throughout our organization, we strive for a zero‑incident safety culture and full compliance with safety regulations. Failure to comply with these requirements can result in sanctions such as fines and penalties and claims for personal injury and property damage. These requirements may also result in increased operating and capital costs in the future.
Worker safety and health matters are overseen by our corporate risk management and safety department as well as operating company level safety managers. We provide our operating company level safety managers leadership and support, comprehensive training, and other tools designed to accomplish health and safety goals, reduce risk, eliminate hazards, and ultimately make our work places safer.

Risks Related to Our Industry and Our Business

Industry Risks
Our business depends on activity within the construction industry and the strength of the local economies in which we operate.
We sell most of our construction materials and products and provide all of our paving and related services to the construction industry, so our results are significantly affected by the strength of the construction industry. Federal and state budget issues may negatively affect the amount of funding available for infrastructure spending, particularly highway construction, which constitutes a significant portion of our business. Demand for our products, particularly in the residential and nonresidential construction markets, could decline if companies and consumers cannot obtain funding for construction projects. In addition, a slow pace of economic activity typically results in delays or cancellations of capital projects.
Our earnings depend on the strength of the local economies in which we operate because of the high cost to transport our products relative to their price. Although some states in recent years, such as Texas, have increased their budgets for road construction, maintenance, rehabilitation and acquiring right of way for public roads, certain other states, such as Kentucky, have reduced their construction spending due to budget shortfalls from lower tax revenue and other factors. As a result, there has been a reduction in certain states’ investment in infrastructure spending. If economic and construction activity diminishes in one or more areas, particularly in our top revenue‑generating markets of Texas, Utah, Kansas and Missouri, our financial condition, results of operations and liquidity could be materially adversely affected.
Our business is cyclical and requires significant working capital to fund operations.
Our business is cyclical and requires that we maintain significant working capital to fund our operations. Our ability to generate sufficient cash flow depends on future performance, which will be subject to general economic conditions, industry cycles and financial, business and other factors affecting our operations, many of which are beyond our control. If we are unable to generate sufficient cash to operate our business and service our outstanding debt and other obligations, we may be required, among other things, to further reduce or delay planned capital or operating expenditures, sell assets or take other measures, including the restructuring of all or a portion of our debt, which may only be available, if at all, on unsatisfactory terms.
Weather can materially affect our business and we are subject to seasonality.
Nearly all of the products we sell and the services we provide are used or performed outdoors. Therefore, seasonal changes and other weather‑related conditions can adversely affect our business and operations through a decline in both the use and production of our products and demand for our services. Adverse weather conditions such as heavy or sustained rainy and cold weather in the spring and fall can reduce demand for our products and reduce sales, render our contracting operations less efficient or restrict our ability to ship our products. For example, unusually severe flooding conditions on the Mississippi River during the first half of 2019, negatively impacted our operations which affected our financial results. Major weather events such as hurricanes, tornadoes, tropical storms and heavy snows have adversely affected and could adversely affect sales in the near term and may be more severe due to climate change. In particular, our operations in the southeastern and Gulf Coast regions of the United States are at risk for hurricane activity, most notably in August, September and October. For example, in 2017, Hurricane Harvey adversely affected our operations not only during the days immediately before and after the storm, but also in the weeks and months after the storm as our customers recovered and reallocated resources in response to damage caused by the storm.
Construction materials production and shipment levels follow activity in the construction industry, which typically occurs in the spring, summer and fall. Warmer and drier weather during the second and third quarters of our fiscal year typically result in higher activity and revenue levels during those quarters. The first quarter of our fiscal year has typically lower levels of activity due to the weather conditions. Our second quarter varies greatly with spring rains and wide temperature variations. A cool wet spring increases drying time on projects, which can delay sales in the second quarter, while a warm dry spring may enable earlier project startup. Such adverse weather conditions can adversely affect our business, financial condition and results of operations if they occur with unusual intensity, during abnormal periods or last longer than usual in our major markets, especially during peak construction periods.


Table of Contents
Our industry is capital intensive and we have significant fixed and semi‑fixed costs. Therefore, our profitability is sensitive to changes in volume.
The property and machinery needed to produce our materials and products can be very expensive. Therefore, we need to spend a substantial amount of capital to purchase and maintain the equipment necessary to operate our business. Although we believe that our current cash balance, along with our projected internal cash flows and our available financing resources, will provide sufficient cash to support our currently anticipated operating and capital needs, if we are unable to generate sufficient cash to purchase and maintain the property and machinery necessary to operate our business, we may be required to reduce or delay planned capital expenditures or incur additional debt. In addition, given the level of fixed and semi‑fixed costs within our business, particularly at our cement production facilities, decreases in volumes could have a material adverse effect on our financial condition, results of operations and liquidity.
Within our local markets, we operate in a highly competitive industry.
The U.S. construction aggregates industry is highly fragmented with a large number of independent local producers in a number of our markets. Additionally, in most markets, we compete against large private and public infrastructure companies, some of which are also vertically‑integrated. Therefore, there is intense competition in a number of the markets in which we operate. This significant competition could lead to lower prices, lower sales volumes and higher costs in some markets, negatively affecting our financial condition, results of operations and liquidity.
Growth Risks
The success of our business depends in part on our ability to execute on our acquisition strategy.
A significant portion of our historical growth has occurred through acquisitions, and we will likely execute acquisition transactions in the future. We are presently evaluating, and we expect to continue to evaluate on an ongoing basis, possible acquisition transactions. We are presently engaged, and at any time in the future we may be engaged, in discussions or negotiations with respect to possible acquisitions, including larger transactions that would be significant to us. We regularly make, and we expect to continue to make, non‑binding acquisition proposals, and we may enter into letters of intent, in each case allowing us to conduct due diligence on a confidential basis. In addition, from time to time we may enter into dispositions or other transactions involving certain of our assets or businesses. We cannot predict the timing of any contemplated transactions. To successfully acquire a significant target, we may need to raise additional capital through additional equity issuances, additional indebtedness, or a combination of equity and debt issuances. There can be no assurance that we will enter into definitive agreements with respect to any contemplated transactions or that they will be completed. Our acquisition related growth has placed, and will continue to place, significant demands on our management and operational and financial resources. Acquisitions involve risks that, among other things, the businesses acquired will not perform as expected.
Our results of operations from these acquisitions could, in the future, result in impairment charges for any of our intangible assets, including goodwill, or other long‑lived assets, particularly if economic conditions worsen unexpectedly. As a result of these changes, our financial condition, results of operations and liquidity could be materially adversely affected. In addition, many of the businesses that we have acquired and will acquire have unaudited financial statements that have been prepared by the management of such companies and have not been independently reviewed or audited. We cannot assure you that the financial statements of companies we have acquired or will acquire would not be materially different if such statements were independently reviewed or audited. If such statements were to be materially different, the tangible and intangible assets we acquire may be more susceptible to impairment charges, which could have a material adverse effect on us.
The success of our business depends on our ability to successfully integrate acquisitions.
Acquisitions may require integration of the acquired companies’ sales and marketing, distribution, production, purchasing, information technology, finance and administrative organizations. We may not be able to integrate successfully any business we may acquire or have acquired into our existing business and any acquired businesses may not be profitable or as profitable as we had expected. Our inability to complete the integration of new businesses in a timely and orderly manner could increase costs and lower profits. Factors affecting the successful integration of acquired businesses include, but are not limited to, the following:
We may become liable for certain liabilities of any acquired business, whether or not known to us. These risks could include, among others, tax liabilities, product liabilities, environmental liabilities and liabilities for employment practices. These liabilities may be significant.


Table of Contents
Substantial attention from our senior management and the management of the acquired business may be required, which could decrease the time that they have to service and attract customers.

Capital equipment at acquired businesses may require additional maintenance or need to be replaced sooner than we expected.

The complete integration of acquired companies depends, to a certain extent, on the full implementation of our financial systems and policies.

We may actively pursue a number of opportunities simultaneously and we may encounter unforeseen expenses, complications and delays, including difficulties in employing sufficient staff and maintaining operational and management oversight.

The success of our business depends on our ability to retain key employees of our acquired businesses.
We cannot assure you we will be able to retain local managers and employees who are important to the operations of our acquired businesses. The loss of key employees may have an adverse effect on the acquired business and on our business as a whole.
Our long‑term success is dependent upon securing and permitting aggregate reserves in strategically located areas. The inability to secure and permit such reserves could negatively affect our earnings in the future.
Aggregates are bulky and heavy and therefore difficult to transport efficiently. Because of the nature of the products, the freight costs can quickly surpass production costs. Therefore, except for geographic regions that do not possess commercially viable deposits of aggregates and are served by rail, barge or ship, the markets for our products tend to be localized around our quarry sites and are served by truck. New quarry sites often take a number of years to develop. Our strategic planning and new site development must stay ahead of actual growth. Additionally, in a number of urban and suburban areas in which we operate, it is increasingly difficult to permit new sites or expand existing sites due to community resistance. Therefore, our future success is dependent, in part, on our ability to accurately forecast future areas of high growth in order to locate optimal facility sites and on our ability to either acquire existing quarries or secure operating and environmental permits to open new quarries. If we are unable to accurately forecast areas of future growth, acquire existing quarries or secure the necessary permits to open new quarries, our financial condition, results of operations and liquidity could be materially adversely affected.
Economic Risks

The ongoing outbreak of the novel coronavirus (COVID-19) has caused severe disruptions in the U.S. and global economy and is expected to continue to adversely impact the economy, at least for the near term. While the full scale and scope of the long-term effects of the COVID-19 outbreak are unknown at this time, the overall impact on our business, operating results, cash flows and/or financial condition could be material.

As of the date of this report, there is an ongoing outbreak of COVID-19, which has spread to over 200 countries and territories, including the United States, and to every state in the United States. The United States and other countries have reacted to the COVID-19 outbreak with unprecedented government intervention. The global impact of the outbreak has been rapidly evolving, and many countries have reacted by instituting, or strongly encouraging quarantines and restrictions on travel, closing financial markets and/or restricting trading, limiting operations of non-essential businesses, and taking other restrictive measures designed to help slow the spread of COVID-19. Such actions are disrupting global supply chains, increasing rates of unemployment and adversely impacting many industries. The outbreak has had an adverse impact on economic and market conditions. The outbreak of COVID-19 caused significant volatility on the market price of our Class A common stock and the extent of its impact on our future results of operations and overall financial performance remains uncertain.

The scale and scope of the COVID-19 pandemic may heighten the potential adverse effects on our business, operating results, cash flows and/or financial condition of the risks described in this report, including the impact of:

potentially unfavorable economic conditions for our clients and customers, particularly in the residential and non-residential sectors, and the construction industry generally;
delays or cancellation of projects and delays in collecting on certain of our accounts receivable from our customers;

Table of Contents
increased costs associated with compliance with new government regulations or restrictions, such as quarantines or social distancing mandates, which regulations or restrictions may curtail our normal operations in one or more of the markets in which we operate;
significant disruptions at one or more of our locations, which could disrupt our operations, raise costs and reduce revenue and earnings in the affected areas;
fluctuations in equity market prices (including that of our Class A common stock), interest rates and credit spreads limiting our ability to raise or deploy capital and affecting our overall liquidity: and
a sustained longer term reduction in cash flows may be an indication some or all of our goodwill may not be realizable.

In addition, the COVID-19 pandemic has to date and may further adversely impact our business and financial condition in other areas, including as a result of:

increased costs, including as a result of implementing health and safety protocols at our locations;
disruptions to our supply and distribution channels, including delivery trucks;
lower sales volumes due to reduced demand; and
reduced state and local transportation budgets, particularly if such are not augmented by federal funding or if the federal government fails to act on a highway infrastructure bill.

The fluidity of this situation precludes any prediction as to the ultimate adverse impact of COVID-19 on economic and market conditions, and, as a result, present material uncertainty and risk with respect to our business. The duration and extent of the impact from the COVID-19 pandemic depends on future developments that cannot be accurately predicted at this time, such as the extent and effectiveness of containment actions, the success of vaccination efforts and the impact of these and other factors on our employees, customers, suppliers and partners. It is also possible that negative consequences of the pandemic may continue once the pandemic is controlled.

The adverse impact on our business, financial condition, operating results or liquidity or future results from the COVID-19 pandemic, or any similar future crisis could be material. The inherent uncertainty surrounding COVID-19, and likewise any similar crisis, also makes it more challenging for our management to estimate the future performance of our business and develop strategies to generate growth or achieve our objectives for fiscal 2021.
A decline in public infrastructure construction and reductions in governmental funding could adversely affect our earnings in the future.
A significant portion of our revenue is generated from publicly‑funded construction projects. As a result, if publicly‑funded construction decreases due to reduced federal or state funding or otherwise, our financial condition, results of operations and liquidity could be materially adversely affected.
Under U.S. law, annual funding levels for highways is subject to yearly appropriation reviews. This annual review of funding increases the uncertainty of many state departments of transportation regarding funds for highway projects. This uncertainty could result in states being reluctant to undertake large multi‑year highway projects which could, in turn, negatively affect our sales. We cannot be assured of the existence, amount and timing of appropriations for spending on federal, state or local projects. Federal support for the cost of highway maintenance and construction is dependent on congressional action. In addition, each state funds its infrastructure spending from specially allocated amounts collected from various taxes, typically gasoline taxes and vehicle fees, along with voter‑approved bond programs. Shortages in state tax revenues can reduce the amounts spent on state infrastructure projects, even below amounts awarded under legislative bills. In recent years, certain states have experienced state‑level funding pressures caused by lower tax revenues and an inability to finance approved projects. Delays or cancellations of state infrastructure spending could have a material adverse effect on our financial condition, results of operations and liquidity.
Our business relies on private investment in infrastructure, and periods of economic stagnation or recession may adversely affect our earnings in the future.
A significant portion of our sales are for projects with non‑public owners whose construction spending is affected by developers’ ability to finance projects. Residential and nonresidential construction could decline if companies and consumers are unable to finance construction projects or in periods of economic stagnation or recession, which could result in delays or cancellations of capital projects. If housing starts and nonresidential projects stagnate or decline, sale of our construction materials, downstream products and paving and related services may decline and our financial condition, results of operations and liquidity could be materially adversely affected.

Table of Contents
Environmental, health and safety laws and regulations and any changes to, or liabilities or litigation arising under, such laws and regulations could have a material adverse effect on our financial condition, results of operations and liquidity.
We are subject to a variety of federal, state, provincial and local laws and regulations relating to, among other things: (i) the release or discharge of materials into the environment; (ii) the management, use, generation, treatment, processing, handling, storage, transport or disposal of hazardous materials, including the management of hazardous and non-hazardous waste used as a fuel substitute in our cement kiln in Hannibal, Missouri; (iii) the management, use, generation, treatment, processing, handling, storage, transport or disposal of non‑hazardous solid waste used as a fuel substitute in our cement kiln in Davenport, Iowa; and (iv) the protection of public and employee health and safety and the environment. These laws and regulations impose strict liability in some cases without regard to negligence or fault and expose us to liability for the environmental condition of our currently or formerly owned, leased or operated facilities or third‑party waste disposal sites, and may expose us to liability for the conduct of others or for our actions, even if such actions complied with all applicable laws at the time these actions were taken. In particular, we may incur remediation costs and other related expenses because our facilities were constructed and operated before the adoption of current environmental laws and the institution of compliance practices or because certain of our processes are regulated. These laws and regulations may also expose us to liability for claims of personal injury or property or natural resource damage related to alleged exposure to, or releases of, regulated or hazardous materials. The existence of contamination at properties we own, lease or operate could also result in increased operational costs or restrictions on our ability to use those properties as intended.
There is an inherent risk of liability in the operation of our business, and despite our compliance efforts, we may be in noncompliance with environmental, health and safety laws and regulations from time to time. These potential liabilities or events of noncompliance could have a material adverse effect on our operations and profitability. In many instances, we must have government approvals, certificates, permits or licenses in order to conduct our business, which could require us to make significant capital, operating and maintenance expenditures to comply with environmental, health and safety laws and regulations. Our failure to obtain and maintain required approvals, certificates, permits or licenses or to comply with applicable governmental requirements could result in sanctions, including substantial fines or possible revocation of our authority to conduct some or all of our operations. Governmental requirements that affect our operations also include those relating to air and water quality, waste management, asset reclamation, the operation and closure of municipal waste and construction and demolition debris landfills, remediation of contaminated sites and worker health and safety. These requirements are complex and subject to frequent change, often in connection with changes in the presidential administration. Stricter laws and regulations, more stringent interpretations of existing laws or regulations or the future discovery of environmental conditions may impose new liabilities on us, reduce operating hours, require additional investment by us in pollution control equipment or impede our opening new or expanding existing plants or facilities.
We have incurred, and may in the future incur, significant capital and operating expenditures to comply with such laws and regulations, and in some cases we have been or could be named as a defendant in litigation brought by governmental agencies or private parties. In addition, we have recorded liabilities in connection with our reclamation and landfill closure obligations, but there can be no assurances that the costs of our obligations will not exceed our estimates. The cost of complying with such laws and defending against any litigation could have a material adverse effect on our financial condition, results of operations and liquidity.

We may incur significant costs in connection with pending and future litigation.

We have seen increases in litigation as the scope of our business and operations has grown. We are, or may become, party to various lawsuits, claims, investigations, and proceedings, including but not limited to personal injury, environmental, property entitlements and land use, commercial, contract, product liability, health and safety, and employment matters. The outcome of pending or future lawsuits, claims, investigations, or proceedings is often difficult to predict and could be adverse and material in amount. Development in these proceedings can lead to changes in management’s estimates of liabilities associated with these proceedings including the judge’s rulings or judgments, jury verdicts, settlements, or changes in applicable law. Future adverse rulings, settlements, or unfavorable developments could result in charges that could have a material adverse effect on our results of operations and cash flows in a particular period. In addition, the defense of these lawsuits, claims, investigations, and proceedings may divert our management’s attention, and we may incur significant costs in defending these matters.

Shortages of, or increases in prices for, commodities, labor and other production and delivery inputs could restrict our ability to operate our business and could have significant impacts on our operating costs.


Table of Contents
Shortages of, or increases in prices for, production and delivery inputs, including commodities and labor, and other inputs related to the production and delivery of our products, could adversely affect our business. Our cost of revenue consists of production and delivery inputs, which primarily include labor, utilities, raw materials, fuel, transportation, royalties and other direct costs incurred in the production and delivery of our products and services. Increases in these costs, as a result of general economic conditions, inflationary pressures or otherwise, may reduce our operating margin and adversely affect our financial position if we are unable to hedge or otherwise offset such increases. Specifically, significant increases or fluctuations in the prices of certain energy commodities, including diesel fuel, liquid asphalt and other petroleum-based resources, which we consume significant amounts of in our production and distribution processes, could negatively affect the results of our business operations or cause our results to suffer. Additionally, labor is a meaningful component in our ability to operate our business and can have a significant impact on the cost of operating our business. Labor shortages could restrict our ability to operate our business or result in increased labor costs as a result of wage increases due to competition for qualified workers. Increased labor costs, whether due to labor shortages, changing demographics of the overall work force or otherwise may reduce our operating margin and adversely affect our financial position.

Availability of and pricing for raw materials and labor can be affected by various national, regional, local, economic and political factors. For example, recent government-imposed tariffs and trade regulations on imported raw materials could have significant impacts on our costs to operate our business.
Financial Risks
Difficult and volatile conditions in the credit markets could affect our financial condition, results of operations and liquidity.
Demand for our products is primarily dependent on the overall health of the economy, and federal, state and local public infrastructure funding levels. A stagnant or declining economy tends to produce less tax revenue for public infrastructure agencies, thereby decreasing a source of funds available for spending on public infrastructure improvements, which constitute a significant part of our business.
There is a likelihood that we will not be able to collect on certain of our accounts receivable from our customers. If our customers are unable to obtain credit or unable to obtain credit in a timely manner, they may be unable to pay us, which could have a material adverse effect on our financial condition, results of operations and liquidity.
If we are unable to accurately estimate the overall risks, requirements or costs when we bid on or negotiate contracts that are ultimately awarded to us, we may achieve lower than anticipated profits or incur contract losses.
Even though the majority of our government contracts contain raw material escalators to protect us from certain input material price increases, a portion or all of the contracts are often on a fixed cost basis. Pricing on a contract with a fixed unit price is based on approved quantities irrespective of our actual costs and contracts with a fixed total price require that the total amount of work be performed for a single price irrespective of our actual costs. We realize profit on our contracts only if our revenue exceeds actual costs, which requires that we successfully estimate our costs and then successfully control actual costs and avoid cost overruns. If our cost estimates for a contract are inadequate, or if we do not execute the contract within our cost estimates, then cost overruns may cause us to incur a loss or cause the contract not to be as profitable as we expected. The costs incurred and profit realized, if any, on our contracts can vary, sometimes substantially, from our original projections due to a variety of factors, including, but not limited to:
failure to include materials or work in a bid, or the failure to estimate properly the quantities or costs needed to complete a lump sum contract;

delays caused by weather conditions or otherwise failing to meet scheduled acceptance dates;

contract or project modifications or conditions creating unanticipated costs that are not covered by change orders;

changes in availability, proximity and costs of materials, including liquid asphalt, cement, aggregates and other construction materials (such as stone, gravel, sand and oil for asphalt paving), as well as fuel and lubricants for our equipment;

to the extent not covered by contractual cost escalators, variability and inability to predict the costs of purchasing diesel, liquid asphalt and cement;


Table of Contents
availability and skill level of workers;

failure by our suppliers, subcontractors, designers, engineers or customers to perform their obligations;

fraud, theft or other improper activities by our suppliers, subcontractors, designers, engineers, customers or our own personnel;

mechanical problems with our machinery or equipment;

citations issued by any governmental authority, including OSHA and MSHA;

difficulties in obtaining required governmental permits or approvals;

changes in applicable laws and regulations;

uninsured claims or demands from third parties for alleged damages arising from the design, construction or use and operation of a project of which our work is part; and

public infrastructure customers may seek to impose contractual risk‑shifting provisions more aggressively which may result in us facing increased risks.

These factors, as well as others, may cause us to incur losses, which could have a material adverse effect on our financial condition, results of operations and liquidity.
We could incur material costs and losses as a result of claims that our products do not meet regulatory requirements or contractual specifications.
We provide our customers with products designed to meet building code or other regulatory requirements and contractual specifications for measurements such as durability, compressive strength, weight‑bearing capacity and other characteristics. If we fail or are unable to provide products meeting these requirements and specifications, material claims may arise against us and our reputation could be damaged. Additionally, if a significant uninsured, non‑indemnified or product‑related claim is resolved against us in the future, that resolution could have a material adverse effect on our financial condition, results of operations and liquidity.
The cancellation of a significant number of contracts or our disqualification from bidding for new contracts could have a material adverse effect on our financial condition, results of operations and liquidity.
We could be prohibited from bidding on certain government contracts if we fail to maintain qualifications required by the relevant government entities. In addition, contracts with governmental entities can usually be canceled at any time by them with payment only for the work completed. A cancellation of an unfinished contract or our disqualification from the bidding process could result in lost revenue and cause our equipment to be idled for a significant period of time until other comparable work becomes available, which could have a material adverse effect on our financial condition, results of operations and liquidity.
Our operations are subject to special hazards that may cause personal injury or property damage, subjecting us to liabilities and possible losses which may not be covered by insurance.
Operating hazards inherent in our business, some of which may be outside our control, can cause personal injury and loss of life, damage to or destruction of property, plant and equipment and environmental damage. We maintain insurance coverage in amounts and against the risks we believe are consistent with industry practice, but this insurance may not be adequate or available to cover all losses or liabilities we may incur in our operations. Our insurance policies are subject to varying levels of deductibles. However, liabilities subject to insurance are difficult to estimate due to unknown factors, including the severity of an injury, the determination of our liability in proportion to other parties, the number of incidents not reported and the effectiveness of our safety programs. If we were to experience insurance claims or costs above our estimates, our financial condition, results of operations and liquidity could be materially adversely affected.
Unexpected factors affecting self‑insurance claims and reserve estimates could adversely affect our business.

Table of Contents
We use a combination of third‑party insurance and self‑insurance to provide for potential liabilities for workers’ compensation, general liability, vehicle accident, property and medical benefit claims. Although we seek to minimize our exposure on individual claims, for the benefit of costs savings we have accepted the risk of multiple independent material claims arising. We estimate the projected losses and liabilities associated with the risks retained by us, in part, by considering historical claims experience, demographic and severity factors and other actuarial assumptions which, by their nature, are subject to a high degree of variability. Among the causes of this variability are unpredictable external factors affecting future inflation rates, discount rates, litigation trends, legal interpretations, benefit level changes and claim settlement patterns. Any such matters could have a material adverse effect on our financial condition, results of operations and liquidity.

Our substantial leverage could adversely affect our financial condition, our ability to raise additional capital to fund our operations, our ability to operate our business, our ability to react to changes in the economy or our industry and our ability to pay our debts, which could divert our cash flow from operations to debt payments.
We are highly leveraged. As of January 2, 2021, our total debt was approximately $1.9 billion, which includes $1.3 billion of Senior Notes and $616.3 million of senior secured indebtedness under our senior secured credit facilities and we had an additional $329.1 million of unutilized capacity under our senior secured revolving credit facility (after giving effect to approximately $15.9 million of letters of credit outstanding).
Our high degree of leverage could have important consequences, including:
increasing our vulnerability to general economic and industry conditions;

requiring a substantial portion of cash flow from operations to be dedicated to the payment of principal and interest on our indebtedness, thereby reducing our ability to use our cash flow to fund our operations, capital expenditures and future business opportunities;

the deductibility of our interest expense is currently limited under existing law and would be further limited if proposed regulations are finalized in their current form;

subject us to the risk of increased interest rates as a portion of our borrowings under our senior secured credit facilities are exposed to variable rates of interest;

restricting us from making strategic acquisitions or causing us to make non-strategic divestitures;

limiting our ability to obtain additional financing for working capital, capital expenditures, debt service requirements, acquisitions and general corporate or other purposes;

limiting our ability to adjust to changing market conditions and placing us at a competitive disadvantage compared to our competitors who are less highly leveraged; and

making it more difficult for us to make payments on our debt.

Borrowings under our senior secured credit facilities are at variable rates of interest and expose us to interest rate risk. If interest rates increase, our debt service obligations on the variable rate indebtedness will increase even though the amount borrowed remained the same, and our net income and cash flows, including cash available for servicing our indebtedness, will correspondingly decrease. We historically have and may in the future enter into interest rate swaps that involve the exchange of floating for fixed rate interest payments in order to reduce interest rate volatility. However, we may not maintain interest rate swaps with respect to all of our variable rate indebtedness, and any interest rate swaps we enter into may not fully mitigate our interest rate risk. In addition, certain of our variable rate indebtedness uses London Inter-bank Offered Rate (“LIBOR”) as a benchmark for establishing the rate of interest. LIBOR has been the subject of national, international and other regulatory guidance and proposals for reform. The United Kingdom's Financial Conduct Authority, which regulates LIBOR, announced in 2017 that it intends to stop encouraging banks to submit LIBOR rates after 2021. However, the ICE Benchmark Administration, in its capacity as administrator of USD LIBOR, has announced that it intends to extend publication of USD LIBOR (other than one-week and two-month tenors) by 18 months to June 2023. Notwithstanding this possible extension, a joint statement by key regulatory authorities calls on banks to cease entering into new contracts that use USD LIBOR as a reference rate by no later than December 31, 2021. The consequences of these developments cannot be entirely predicted, but could include an increase in the cost of our variable rate indebtedness. If LIBOR ceases to exist or if the methods of calculating LIBOR change from their current form, we may also need to renegotiate our variable rate indebtedness that utilizes LIBOR as a factor in determining the interest rate to replace LIBOR with the new standard that is established. In addition, the

Table of Contents
indentures that govern the Senior Notes and the amended and restated credit agreement governing our senior secured credit facilities (“Credit Agreement”) contain restrictive covenants that limit our ability to engage in activities that may be in our long-term best interest. Our failure to comply with those covenants could result in an event of default which, if not cured or waived, could result in the acceleration of all our debt.
Despite our current level of indebtedness, we and our subsidiaries may still incur substantially more debt. This could reduce our ability to satisfy our current obligations and further exacerbate the risks to our financial condition described above.
We and our subsidiaries may incur significant additional indebtedness in the future to fund acquisitions as part of our growth strategy. Although the indentures governing the Senior Notes and the Credit Agreement contain restrictions on the incurrence of additional indebtedness, these restrictions are subject to a number of qualifications and exceptions, and we could incur substantial additional indebtedness in compliance with these restrictions.
Our senior secured credit facilities include an uncommitted incremental facility that allows us the option to increase the amount available under the term loan facility and/or the senior secured revolving credit facility by (i) $225.0 million plus (ii) an additional amount so long as we are in pro forma compliance with a consolidated first lien net leverage ratio. Availability of such incremental facilities will be subject to, among other conditions, the absence of an event of default and the receipt of commitments by existing or additional financial institutions.

We may not be able to generate sufficient cash to service all of our indebtedness and may be forced to take other actions to satisfy our obligations under our indebtedness, which may not be successful.
Our ability to make scheduled payments on our debt obligations, refinance our debt obligations and fund planned capital expenditures and other corporate expenses depends on our financial condition and operating performance, which is subject to prevailing economic and competitive conditions. We are also subject to certain financial, business, legislative, regulatory and legal restrictions on the payment of distributions and dividends. Many of these factors are beyond our control. We may not be able to maintain a level of cash flows from operating activities sufficient to permit us to pay the principal, premium, if any, and interest on our indebtedness, which would constitute an event of default if not cured. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources.” If our cash flows and capital resources are insufficient to fund our debt service obligations or our other needs, we may be forced to reduce or delay investments and capital expenditures, seek additional capital, restructure or refinance our indebtedness or sell assets. These alternative measures may not be successful and may not permit us to meet our scheduled debt service obligations or fund planned capital expenditures. Significant delays in our planned capital expenditures may materially and adversely affect our future revenue prospects. In addition, our ability to restructure or refinance our debt will depend on the capital markets and our financial condition at such time. Any refinancing of our debt could be at higher interest rates and may require us to comply with more onerous covenants, which could further restrict our business operations. The Credit Agreement and the indentures governing the Senior Notes restrict our ability to use the proceeds from asset sales. We may not be able to consummate those asset sales to raise capital or sell assets at prices that we believe are fair and proceeds that we do receive may not be adequate to meet any debt service obligations then due. In addition, any failure to make payments of interest and principal on our outstanding indebtedness on a timely basis would likely result in a reduction of our credit rating, which could harm our ability to incur additional indebtedness.
The indentures governing the Senior Notes and the Credit Agreement contain covenants and provisions that are restrictive.
The indentures governing the Senior Notes and Credit Agreement contain restrictive covenants that, among other things, limit our ability, and the ability of our restricted subsidiaries, to:
incur additional indebtedness, issue certain preferred shares or issue guarantees;

pay dividends, redeem our membership interests or make other restricted payments, including purchasing our Class A common stock;

make investments, loans or advances;

incur additional liens;

transfer or sell assets;

merge or engage in consolidations;

enter into certain transactions with our affiliates;

designate subsidiaries as unrestricted subsidiaries;

repay subordinated indebtedness; and

change our lines of business.

The senior secured credit facilities also require us to maintain a maximum first lien net leverage ratio. The Credit Agreement also contains certain customary representations and warranties, affirmative covenants and events of default (including, among others, an event of default upon a change of control). If an event of default occurs, the lenders under our senior secured credit facilities will be entitled to take various actions, including the acceleration of amounts due under our senior secured credit facilities and all actions permitted to be taken by a secured creditor. Our failure to comply with obligations under the indentures governing the Senior Notes and the Credit Agreement may result in an event of default under the indenture or the amended and restated Credit Agreement. A default, if not cured or waived, may permit acceleration of our indebtedness. If our indebtedness is accelerated, we may not have sufficient funds available to pay the accelerated indebtedness or the ability to refinance the accelerated indebtedness on terms favorable to us or at all.
Other Risks
Our success is dependent on our senior management team and our ability to retain and attract qualified personnel.
Our success depends on the continuing services of key members of our management team. We believe our senior management team possesses valuable knowledge and skills that are crucial to our success and would be difficult to replicate or replace.
Competition for senior management is intense, and we may not be able to retain our management team or attract additional qualified personnel. The unexpected loss of a member of senior management has in the past and could in the future require certain of our remaining senior officers to divert immediate attention, which can be substantial or require costly external resources in the short term. While we are developing plans for key management succession and have long-term compensation plans designed to retain our senior employees, if our retention and succession plans do not operate effectively, our business could be adversely affected. The inability to adequately fill vacancies in our senior executive positions on a timely basis could negatively affect our ability to implement our business strategy, which could have a material adverse effect on our results of operations, financial condition and liquidity.
We use large amounts of electricity, diesel fuel, liquid asphalt and other petroleum‑based resources that are subject to potential reliability issues, supply constraints and significant price fluctuation, which could have a material adverse effect on our financial condition, results of operations and liquidity.
In our production and distribution processes, we consume significant amounts of electricity, diesel fuel, liquid asphalt and other petroleum‑based resources. The availability and pricing of these resources are subject to market forces that are beyond our control. Furthermore, we are vulnerable to any reliability issues experienced by our suppliers, which also are beyond our control. Our suppliers contract separately for the purchase of such resources and our sources of supply could be interrupted should our suppliers not be able to obtain these materials due to higher demand or other factors that interrupt their availability. Variability in the supply and prices of these resources could have a material adverse effect on our financial condition, results of operations and liquidity.
Climate change and climate change legislation or regulations may adversely affect our business.
A number of governmental bodies have finalized, proposed or are contemplating legislative and regulatory changes in response to the potential effects of climate change, and Canada and the United States have agreed to the Paris Agreement, the successor to the Kyoto Protocol to the United Nations Framework Convention on Climate Change, which could lead to additional legislative and regulatory changes in those countries. In addition, in the United States, there may be additional legislative and regulatory changes in connection with the recent change in presidential administration. Such legislation or regulation has and potentially could include provisions for a “cap and trade” system of allowances and credits, among other provisions. The EPA promulgated a mandatory reporting rule covering greenhouse gas (“GHG”) emissions from sources considered to be large emitters. The EPA has also promulgated a GHG emissions permitting rule, referred to as the “Tailoring

Table of Contents
Rule” which sets forth criteria for determining which facilities are required to obtain permits for GHG emissions pursuant to the U.S. Clean Air Act’s Prevention of Significant Deterioration (“PSD”) and Title V operating permit programs. The U.S. Supreme Court ruled in June 2014 that the EPA exceeded its statutory authority in issuing the Tailoring Rule but upheld the Best Available Control Technology (“BACT”) requirements for GHGs emitted by sources already subject to PSD requirements for other pollutants. Our cement plants and one of our landfills hold Title V Permits. If future modifications to our facilities require PSD review for other pollutants, GHG BACT requirements may also be triggered, which could require significant additional costs.
Other potential effects of climate change include physical effects such as disruption in production and product distribution as a result of major storm events and shifts in regional weather patterns and intensities. There is also a potential for climate change legislation and regulation to adversely affect the cost of purchased energy and electricity.
The effects of climate change on our operations are highly uncertain and difficult to estimate. However, because a chemical reaction inherent to the manufacture of Portland cement releases carbon dioxide, a GHG, cement kiln operations may be disproportionately affected by future regulation of GHGs. Climate change and legislation and regulation concerning GHGs could have a material adverse effect on our financial condition, results of operations and liquidity.
Unexpected operational difficulties at our facilities could disrupt operations, raise costs, and reduce revenue and earnings in the affected locations.
The reliability and efficiency of certain of our facilities is dependent upon vital pieces of equipment, such as our cement manufacturing kilns in Hannibal, Missouri and Davenport, Iowa. Although we have scheduled outages to perform maintenance on certain of our facilities, vital equipment may periodically experience unanticipated disruptions due to accidents, mechanical failures or other unanticipated events such as fires, explosions, violent weather conditions or other unexpected operational difficulties. A substantial interruption of one of our facilities could require us to make significant capital expenditures to restore operations and could disrupt our operations, raise costs, and reduce revenue and earnings in the affected locations.
We are dependent on information technology. Our systems and infrastructure face certain risks, including cyber security risks and data leakage risks.
We are dependent on information technology systems and infrastructure to carry out important operational activities and to maintain our business records. In addition, we rely on the systems of third parties, such as third-party vendors. As part of our normal business activities, we collect and store certain personal identifying and confidential information relating to our customers, employees, vendors and suppliers, and maintain operational and financial information related to our business. We may share some of this confidential information with our vendors. We rely on our vendors and third-party service providers to maintain effective cybersecurity measures to keep our information secure. Any significant breakdown, invasion, destruction or interruption of our existing or future systems by employees, third parties, vendors, others with authorized access to our systems, or unauthorized persons could negatively affect operations. In addition, future systems upgrades or changes could be time consuming, costly and result in unexpected interruptions or other adverse effects on our business. There is also a risk that we could experience a business interruption, theft of information or reputational damage as a result of a cyber-attack, such as an infiltration of a data center, or data leakage of confidential information either internally or at our third‑party providers.

While we have invested in the protection of our data and information technology to reduce these risks and periodically test the security of our information systems network, there can be no assurance that our efforts will prevent breakdowns or breaches in our systems that could have a material adverse effect on our financial condition, results of operations and liquidity. Our or our vendors’ and third-party service providers’ failure to maintain the security of the data we are required to protect could result in damage to our reputation, financial obligations to third parties, fines, penalties, regulatory proceedings and private litigation with potentially large costs, and also in deterioration in customers’ confidence in us and other competitive disadvantages. While, to date, we have not had a significant cybersecurity breach or attack that has a material impact on our business or results of operations, there can be no assurance that our efforts to maintain the security and integrity of our information technology networks and related systems will be effective or that attempted security breaches or disruptions would not be successful or damaging.
Labor disputes, strikes, other forms of work stoppage or slowdown or other union activities could disrupt operations of our businesses.
As of January 2, 2021, labor unions represented approximately 7% of our total employees, substantially all in our cement division and at our Canadian operations. Our collective bargaining agreements for employees generally expire between

Table of Contents
2022 and 2026. Although we believe we have good relations with our employees and unions, disputes with our trade unions, union organizing activity, or the inability to renew our labor agreements or adverse labor relations at any of our locations, could lead to strikes, other forms of work stoppage, slowdowns or other actions that could disrupt our operations and, consequently, have a material adverse effect on our financial condition, results of operations and liquidity.
Organizational Structure Risks
Summit Inc.’s only material asset is its interest in Summit Holdings, and it is accordingly dependent upon distributions from Summit Holdings to pay taxes, make payments under the TRA and pay dividends.
Summit Inc. is a holding company and has no material assets other than its ownership of LP Units and has no independent means of generating revenue. Summit Inc. intends to cause Summit Holdings to make distributions to holders and former holders of LP Units in an amount sufficient to cover all applicable taxes at assumed tax rates, payments under the TRA and cash distributions, if any, declared by it.
